Description

Technical Field

[0001] The subject matter of the present invention relates to crimping tools, systems, and / or components associated with crimping tools, and methods involving crimping tools and related components. Background Art

[0002] Currently, many commercially available crimping tools have only a single output force, such as 32 kN, 24 kN, or 18 kN tools. In contrast, different sized fittings require different forces to produce sufficient deformation during crimping. For example, fittings under 1 inch require an output force of approximately 18 kN, 1 to 1 / 4 inch fittings require an output force of approximately 24 kN, and 2 inch fittings require an output force of approximately 32 kN.

[0003] If a single tool, such as a tool providing an output force of 32 kN, is used to crimp all sized fittings, a significant amount of energy will be wasted. This can be problematic, especially for battery-powered tools. Also, the high output force will require that all jaws, regardless of size, must have sufficient material properties and / or hardness. For example, a 32 kN tool can only use standard jaws that are relatively large and made of relatively strong materials. Thus, a 32 kN tool cannot use smaller, compact jaws that can be made of less strong materials.

[0004] Furthermore, market research shows that typical crimping tool purchasers prefer high-capacity crimping tools, such as 32 kN tools, which are most often used with 2 inch fittings. However, most crimping applications involve fittings sized 1 inch or smaller.

[0005] Accordingly, there is a need for a crimping tool or tool system that addresses these problems. Summary of the Invention

[0036] As pressing tools have evolved, they have become lighter and more compact in size. The only component in a pressing tool that has not changed significantly is the pressing clamp or clamp assembly. On the one hand, the subject matter of the present invention allows designers to optimize smaller pressing clamps suitable for the requirements of practical applications, for example, for use with a specific fitting size or range of fitting sizes. This will result in a significant reduction in the weight of the clamp, a reduction in the material requirements of the clamp, and / or a significant improvement in the cycle life of the clamp.

[0037] According to another aspect of the subject matter of the present invention, the pressing clamp and the pressing tool are provided with a communication device that enables information about the clamp to be used and engaged with the pressing tool to be transmitted or otherwise provided to the pressing tool. The pressing tool includes a communication device for receiving information from the clamp and may optionally also include an information processing device for analyzing and / or monitoring the information transmitted or provided by the clamp. In many embodiments, the pressing tool also includes means for restricting or controlling the force output of the pressing tool based on the clamp, more specifically based on the information transmitted or provided by the clamp.

[0038] In certain embodiments of the subject matter of the present invention, the user is able to receive an alert that a necessary service is due or that the clamp is approaching the end of its useful life. This enables the user to make the appropriate preparations and improve the uptime of the work site. These aspects can potentially be combined with the aspect of the tool being wirelessly connected. These and other aspects are described herein.

[0039] Figure 1An embodiment of a clamping tool with jaws in accordance with the subject matter of the present invention is shown. When the user pushes or otherwise actuates a trigger, an electric motor in the clamping tool powers a pump in the tool that pumps oil from a reservoir in the tool into a working cylinder also located in the tool. As the pressure in the working cylinder increases, a piston in the tool is pushed onto a plunger that can extend from the tool.

[0040] Specifically, Figure 1 A clamping tool 50 with a jaw set 10 engaged therewith is shown. The clamping tool 50 includes an electric motor, typically an electric motor 52 actuated by a displaceable trigger 54. The clamping tool 50 further includes a pump 56 for pumping a hydraulic fluid or hydraulic oil from a reservoir 58 into a working hydraulic cylinder 60. A piston 62 is movably disposed in the cylinder 60 and is capable of being displaced by the action of the hydraulic fluid in the cylinder to engage and correspondingly displace a plunger 64.

[0041] Further referring Figure 1 , at the working or front end of the clamping tool 50, the jaw set 10, a clamping jaw assembly or a pair of jaws is detachably connected to a jaw pin 70 as Figure 2 separately shown. The jaw set 10 includes two opposing jaw arms 12, each jaw arm having a clamping profile at one end and generally two cam profiles at the opposite end. The two jaw arms 12 are held or retained between two T-shaped side plates 14, 16 by two side plate pins 18. The T-shaped side plates 14, 16 define a hole 28 through which the jaw pin 70 passes to connect the clamping jaw assembly 10 to the clamping tool 50. By pulling out and removing the jaw pin 70 from the hole 28, the clamping jaws 10 can be removed from the clamping tool 50.

[0042] Figure 3 and Figure 4 Another embodiment of the jaw set 10 is shown, which includes a pair of jaw arm members 12 that are respectively mounted or held between the side plates 14 and 16 in the directions as Figure 3 and Figure 4 shown by corresponding pivot or bearing pins 18. Each of the jaw arm members 12 has a first side 20, a second side 22 and a pin opening 24 through which the corresponding pin 18 is passed to be received. The side plates 14 and 16 are generally T-shaped and respectively include laterally opposite sides 14a and 16a, and the opposite sides are respectively provided with aligned holes 26 for receiving the outer ends of the corresponding pins 18. The side plates 14 and 16 also respectively include rear ends 14b and 16b, and aligned openings 28 are provided through the rear ends, and the aligned openings are adapted to receive such as Figure 1The mounting pin or clamping pin of the clamping pin 70 shown, and the clamping group is mounted on a drive unit for, e.g., a pressing tool, in a well-known manner through the mounting pin or clamping pin. The clamping arm members 12 and the side plates 14, 16 are held in an assembled relationship by spring clips 30 at opposite ends of each of the pins 18.

[0043] Each of the clamping arm members 12 respectively has longitudinally opposite front ends 12a and rear ends 12b, and respectively has transverse outer edges 32 and inner edges 34, which are spaced apart from the opening 24 and extend in front of and behind the opening. The inner edge 34 of the clamping arm member 12 is provided with opposite clamping recesses or pressing profiles 36 that open transversely inwardly in front of the front end 12a and the side plates, and is provided with transversely inward cam surfaces 38 behind the rear end 12b and the rear ends 14b and 16b of the side plates. The transversely inward inner side 34 of the pin opening 24 houses and supports a hairpin-shaped spring 40, which biases the clamping arm members 12 in opposite directions around the pin 18 to bias the clamping recesses 36 transversely inwardly toward each other. Each of the clamping recesses 36 is integral with the corresponding clamping arm member 12, and the profile of the recess 36 is used to provide a working surface that engages cooperatively around a component part of a fitting, e.g., to be joined by compression.

[0044] Referring Figure 1 and Figure 3 , the plunger 64 of the pressing tool 50 holds a set of rollers 75, and the set of rollers acts on two opposite cam profiles 38 on the clamping arms 12. When the plunger and roller assembly extends outwardly and acts on the two opposite cam profiles 38, the plunger assembly separates the clamping arms 12. The clamping arms 12 rotate around the side plate pins 18 and the working front ends 12a are pushed toward the closed position with the pressing profiles 36.

[0045] Once the pressing clamping assembly 10 reaches the closed position and the tips 36a on the pressing profiles 36 contact each other, the pressure in the cylinder 60 of the pressing tool 50 rapidly increases. Generally, when the preset maximum pressure in the cylinder 60 is reached, the pressure relief valve in the hydraulic circuit opens. This maximum pressure corresponds to the maximum piston force generated and applied to the clamping arms, side plate pins, T-shaped side plates, and central clamping pins. Exemplarily, other details of the pressing tool, clamping assembly, and its operation are provided in U.S. Patent 7,421,871.

[0046] As noted, in use, the clamp set 10 is releasably engaged with a pressing tool, such as pressing tool 50, in a well-known manner by a pin, such as pin 70, which is attached to the pressing tool and received in the side plate opening 28. The ends 12b of the clamp arm members 12 are then manually shifted toward each other to pivot the arm members about the pin 18 against the bias of the spring 40 to open the clamp recess 36 to receive, for example, a pipe fitting and coupler to be compressed, and when the clamp arm members are released, the spring 40 closes the clamp recess 36 around the pipe fitting and coupler. The drive unit or pressing tool 50 is then actuated to axially advance the clamp set 10 thereon and simultaneously engage against the cam surface 38 to shift the clamp arm members 12 about the pin 18 to compress the pipe fitting and coupler together with the clamp recess 36. Thereafter, the drive unit 50 is actuated to withdraw the cam roller 75, and the clamp arm members 12 are again manually shifted against the bias of the spring 40 to open the clamp recess 36 to remove the clamp set 10 from the compressed pipe fitting and coupler.

[0047] Not all compression connections require the same maximum force to complete. For example, a common 1 / 2-inch compression fitting may require an axial ram force of approximately 15 kN to complete. This completion is typically indicated by the closing or contact between the clamp tips (e.g., tip 36a as shown in Figure 3 ). In contrast, a 2-inch copper fitting may require the tool to be able to generate a maximum force of 32 kN. However, since the tool is typically operated until the maximum pressure is reached, the compression clamp used for a smaller fitting (i.e., a smaller compression profile) will be subjected to the same force as the compression clamp configured for a larger fitting. Thus, even though the compression connection does not require such a high force, the load-bearing assembly of the smaller clamp needs to be configured to withstand the same load as the larger clamp assembly. As a result, due to the relatively large force required for the compression connection, these smaller clamps end up being heavier than otherwise required.

[0048] In some cases, the components of the compression clamp may be subjected to such high pressures that they suffer fatigue failure after prolonged use. Certain design measures are known to direct these failures to areas of the clamp where the failures are obvious to the user and make it safe such that no components break away from the assembly. Examples of such design measures are provided, for example, in U.S. Patent 7,260,975 or U.S. Patent 7,578,159. A typical failure of the clamp is a crack in the side plate that originates or forms from the side plate pin hole in the side plate. These cracks typically occur after about 10,000 load cycles.

[0049] The subject matter of the present invention enables the pliers to be optimized for the force actually required to complete the clamping connection, rather than designing each pair of pliers based on the maximum tool force and thus overdesigning the pliers for smaller clamping fittings. In one embodiment of the subject matter of the present invention, a passive electronic chip or similar component is embedded or otherwise incorporated into each pair of pliers or assembly to identify and / or provide information related to the pliers assembly. The chip can be an RFID chip or an NFC chip, or any other suitable passive device. The chip or similar component contains or includes information transmitted by the pliers or read or otherwise sensed by the clamping tool. Such information relates to the size, characteristics, force handling capacity, and / or other aspects of the pliers. Figures 1-4 A representative chip 86 incorporated in a pair of pliers 10 is shown. Although in many embodiments, passive chips are used, the subject matter of the present invention also includes the use of active chips.

[0050] Additionally, preferably, the clamping tool is enabled to end the clamping cycle at any pressure up to the maximum pressure that the tool can transmit. The termination of the clamping cycle is at least partially based on information from the pliers. To this end, the clamping tool can be controlled by a pressure sensor and a solenoid valve. For example, a clamping tool with a pressure sensor and a solenoid valve, both located in the hydraulic circuit of the clamping tool, can be used. To increase safety, the tool can also include a pressure relief valve that automatically limits the maximum system pressure. The pressure relief valve is also located in the hydraulic circuit of the clamping tool. Figure 1 A clamping tool 50 is shown, which includes: a pressure sensor 90, which is preferably configured to sense the pressure in the hydraulic circuit of the tool; a solenoid valve 92, which is preferably located in the hydraulic circuit of the tool. The clamping tool 50 can also optionally include a pressure relief valve 94, which is preferably located in the hydraulic circuit of the tool.

[0051] Additionally, in certain embodiments, the tool includes a receiver capable of communicating with and / or receiving information from the chip in the pliers. Before each clamping operation, the tool will "read" information from the chip embedded in the pliers, which may include one or more of the following information elements: the identification code of the clamping pliers, the identification of the clamping fitting, the force value required to complete the clamping connection, and / or a combination of these. Figure 1 A clamping tool 50 with a receiver or communication device 84 for receiving information associated with the pair of pliers assembly to be used with the tool, particularly information associated with a chip such as chip 86 in the pliers, is also shown.

[0052] In yet another embodiment, the look-up table can be programmed or otherwise stored in the tool controller or other storage component to determine the appropriate clamping force and / or tool pressure for the clamp to be installed on the tool. With this information, the tool can set the pressure limit to the correct pressure for the press connection, thus avoiding overloading the clamping jaws beyond the point of completing jaw tip closure. By loading only the load required for the clamping fitting onto the jaws and avoiding "overload" conditions, the load-bearing components can be designed with less material. On the other hand, by keeping the design of the load-bearing components unchanged, a longer fatigue life can be achieved. In fact, making a compromise between a longer life and a lighter weight may be the most desirable design goal. Figure 1 Also shown is a pressing tool 50 having a tool controller 80 and an electronic or digital memory 82.

[0053] In some embodiments, the pressing tool includes a magnetic switch that opens or closes a circuit in the pressing tool. In a particular embodiment, the magnetic switch operates (i.e., opens or closes) a hydraulic valve to release the pressure within the hydraulic circuit of the pressing tool. The magnetic switch can be configured to sense the position of the hydraulic plunger and / or roller of the pressing tool. Figure 1 Further shown is a pressing tool 50 that includes a switch, which is preferably in the form of a magnetic switch 96. Figure 5A and 5B An embodiment of a magnetic switch 96 used in a pressing tool such as the pressing tool 50 according to the subject matter of the present invention is shown. Figure 5B One or more output states of the switch 96 are shown. The switch 96 provides a "normally open" (NO) circuit through contacts 96a and 96b, and a "normally closed" (NC) circuit through contacts 96a and 96c. The switch opens or closes these circuits by actuating the sensing element 96d. The electromagnetic switch 96 can be used in the pressing tool 50 by operating one or more components in the pressing tool, especially by operating a hydraulic valve located in the hydraulic circuit of the pressing tool. Typically, based on the output state of the electromagnetic switch, such a hydraulic valve can be positioned between an open state and a closed state. For example, the magnetic switch 96 in the pressing tool 50 is configured to sense the position of the plunger 64 and / or roller 75. Once that position is reached, the sensing element 96d of the switch 96 is actuated, thereby opening or closing the circuit. One or more of the contacts 96a, 96b, and 96d are in electrical communication with the circuit. For example, the opening or closing of the circuit can in turn actuate a solenoid valve in the hydraulic circuit to release the pressure therein.

[0054] Figure 6is an embodiment of method 100 for showing a set of clamps or a clamp assembly for use with a pressing tool according to the subject matter of the present invention. Method 100 is performed using a clamp assembly including a passive or active electronic chip incorporated into the clamp assembly, the chip being used to identify and / or provide information related to the clamp assembly. Method 100 is also performed using a pressing tool including a communication device for providing information associated with the clamp assembly. When a clamp set such as clamp set 10 and a pressing tool are engaged, in operation 102, the user presses or otherwise actuates the trigger of the pressing tool to initiate the operation of the pressing tool 50. The pressing tool reads or otherwise receives information from the clamp set described herein. For example, the clamp tool can read the chip incorporated in the clamp set 10 and identify the clamp set and its characteristics. This is shown as operation 104. The pressing tool can also evaluate whether there is a clamp set, i.e., engagement with the tool in operation 106. If no engagement is detected or confirmed, an error message is provided by the tool in operation 108. Then, the tool uses the information received from operation 104 and / or 106 to determine a suitable set pressure target, thereby limiting the output force of the pressing tool. The set pressure target can be obtained from a look-up table or matrix stored in the tool memory, or can be calculated according to calculation criteria or algorithms in the tool circuit. It is also contemplated that the tool can request and receive set pressure target information from an external source. These operations are collectively referred to as 110 in Figure 6 . In operation 112, the motor of the pressing tool is started. This in turn operates the hydraulic pump to push the piston and plunger towards the clamp set. The pressure in the hydraulic cylinder or the pipeline in fluid communication therewith will increase accordingly. The pressure sensor monitors the pressure in operation 114 until the pressure target is reached. As understood, as Figure 6 shown, the motor continues to run until the pressure target is reached. Once the pressure sensor senses that the pressure in the hydraulic cylinder / pipeline has reached the pressure target, in operation 116 the tool control circuit opens the solenoid valve to release the pressure in the hydraulic circuit. In operation 118, the motor is stopped. In addition, method 100 can optionally include one or more data collection operations, collectively represented as operations 120 and 122, where a cycle counter can be incremented to count the total cycle, clamp operation cycle, or other operation parameters. Then the information or data from operation 120 can be stored in the digital memory in the tool and / or an external memory. Non-limiting examples of such information can include pressing cycle information, date, time, clamp identification code, and / or the pressure reached. In operation 124, the pressure target value is cleared or otherwise reset. Method 100 ends at 126.

[0055] If the chip is located in the clamp area where fatigue cracks are expected to occur, the chip will be damaged or destroyed when a crack appears. This prevents the clamp from being used even when the crack is not yet visible.

[0056] To simplify the clamp design, in a particular embodiment of the subject matter of the present invention, two or more and typically three or four "load levels" are defined. In addition to being able to set the tool pressure for each clamp separately, these clamps can also be grouped into these load levels. In this way, the load-bearing components of the clamps can be shared among the clamps within one load level.

[0057] As Figure 7 shown in the system shown, the tool can also incorporate data connectivity functions, for example, via Bluetooth, Wifi, or cellular connection. In some embodiments, the tool is configured to store information associated with each crimp, such as date, time, clamp identification, the actual pressure achieved, and combinations of these parameters with other information or data. For example, once the tool is connected, this information can be transmitted to a cloud server. The cloud server can track the number of cycles of each tool, the number of cycles of each clamp, the date and time of each crimp connection, the actual pressure of each crimp connection, and the size and type of the fittings that have been crimped. The cloud server can maintain a complete usage history of each tool and each clamp by combining the information received from different tools in the network. Using this information, the cloud server can provide warnings to the tool owner (or registered user) about upcoming necessary service events for the tool or about specific clamps that are approaching the end of their service life. The cloud server can also provide a complete history of the number of crimp operations, the size of the clamps, and the location of the crimp connections, for example, by using GPS tags created in or otherwise stored in the tool. For example, this information can be used to create a detailed job report.

[0058] The cloud server receives information and data, retains the information and data, manages access and usage permissions, and manages user access and usage of the tools registered in the system. In many embodiments of the subject matter of the present invention, the cloud server is provided by one or more computer servers or units that can be remotely located. As described herein, access to one or more cloud servers is typically through the Internet and can include cloud-based storage, processing, and / or communication. Cloud storage is a model of computer data storage where digital data is physically stored on multiple servers (sometimes in multiple locations), where the physical environment is typically owned and managed by a cloud storage provider, responsible for maintaining the availability and accessibility of the data, as well as the protection and operation of the physical environment.

[0059] The cloud server of the present invention's subject matter may include a database and a data storage device, in which user information is stored and securely retained. Non-limiting examples of the retained information include authorized user names; registrant names (if different from the authorized user names); company or organization names; contact information of users, registrants, and / or companies; the date of first registration of users and / or tools, as well as the dates of subsequent registrations or logins; passwords and other confidential information related to users, registrants, and / or companies; the names or statuses of users, registrants, and / or companies (such as industrial, contractor, builder, or home users); the locations of registered users and / or tools; preset or pre-specified tool parameters to be monitored and their related parameter limits; tool parameters based on actual usage for monitoring; warnings or indicators related to registered tools or users; the statuses of warnings or indicators; and other information and data including IP addresses used for registering smart tools or enabling each tool.

[0060] In selected embodiments, the cloud server may include an electronic communication system or device (wireless and / or cellular) for enabling the cloud server to exchange, transmit, or receive information (such as data collected during the operation of the aforementioned smart tools) from one or more mobile electronic devices, one or more tools, and / or one or more computers. In many embodiments of the present invention's subject matter, the cloud server includes an Internet communication device.

[0061] In many versions of the present invention's subject matter, the tool system and especially the cloud server use cloud-based storage systems and / or cloud-based data processing and storage systems that can be accessed and implemented in a distributed manner using remotely located servers or other computers. Generally, such servers, computers, and / or other devices are accessed via the Internet.

[0062] In conjunction with the present invention's subject matter, cloud-based storage and / or cloud-based processing refer to online storage and / or processing typically hosted by commercial Internet service providers, through which data is stored (virtually or physically) and / or processed across one or more servers. In an embodiment, the term "cloud-based computing" refers to one or more cloud-based data storage, cloud-based data processing, or cloud-based data communication components. Moreover, commercial Internet service providers may include data centers capable of virtualizing certain resources according to customer needs.

However, embodiments of local access to cloud-based storage are not limited to wireless communication, and thus hardwired communication can also be applied to the embodiments described herein.

[0068] Accordingly, the various electronic mobile devices of the subject matter of the present invention are configured to include an electronic communication device between at least one mobile device, one or more tools, and the cloud server. Generally, such electronic communication is transmitted and exchanged via the Internet and typically utilizes a cloud-based infrastructure.

In alternative embodiments of the subject matter of the present invention, the mobile device is configured to run or execute algorithms or "applications" known in the art that facilitate communication with a cloud server and / or intelligent tools.

The algorithm or application can also facilitate user access to, the use of one or more intelligent tools of interest, and / or provide the user with indications and / or warnings regarding the tools and / or the system.

[0071] The tools of the subject matter of the present invention, as well as typical pressing tools, may also include an interconnectivity means that enables the tool to communicate with one or more mobile devices, computers, and / or cloud servers according to the subject matter of the present invention, i.e., for data transfer and / or information exchange. Figure 1 A pressing tool 50 with such an interconnectivity means 85 is shown.

[0072] Figure 7FIG. 200 is an illustration of a system 200 according to the subject matter of the present invention. The system 200 includes one or more cloud servers 210; and one or more power-driven units or power tools such as clamping tools 50a and 50b; and one or more tool attachments such as clamp sets 10a, 10b, 10c, 10d, and 10e. The power tools include connectivity devices such as device 85 for communicating with the cloud server 210 and / or mobile devices. One or more of the tool attachments include chips such as the previously mentioned chip 86, and one or more of the tools include communication devices such as device 84 previously pointed out for receiving information from one or more chips. The system 200 may further include one or more mobile devices such as mobile devices 220a and 220b. The one or more mobile devices include communication devices for data transfer and / or information exchange with other components of the system 200. The mobile devices may additionally include other features described herein. The system 200 may further include one or more computers 230. The computer 230 may include communication devices for data transfer and / or information exchange with any of the cloud server 210, one or more tools 50a, 50b, and / or mobile devices 220a and 220b.

[0073] The subject matter of the present invention also provides a method for monitoring and / or managing tools and their attachments. Further referring Figure 7 , clamps such as clamps 10a, 10b, 10c, 10d, and 10e are divided into two groups, for example, a first group of clamps of 1 to 1 / 4 inches or less that require 24 kN, and a second group of clamps of 1 inch to 2 inches that require 32 kN. The subject matter of the present invention includes using single groups, three groups, four groups, and five groups or more of clamps. For many clamping tools, the default force of the clamping tool is a relatively high force such as 32 kN (53 Mpa). In certain embodiments, one or more clamping tools such as tools 50a and 50b include pressure sensors such as Figure 1 pressure sensor 90 in FIG. 7. In certain embodiments, one or more of the clamping tools such as tools 50a and 50b include magnetic switches to release the hydraulic valve. For example, one or more of tools 50a and 50b can include magnetic switches such as Figure 1 , 5A and magnetic switch 96 shown in FIGS. 5B. The magnetic switch can be configured to release the pressure in the hydraulic circuit of tools 50a and 50b by actuating the hydraulic valve (e.g., Figure 1 previously mentioned solenoid valve 92 shown in FIG. 7).

[0074] This system can be configured to monitor the use of clamps and clamping tools and provide services and / or usage alerts. For example, further referringFigure 7 The compression cycle of each clamp group in the statistical system is counted and the cumulative total is monitored. The total cycle of each clamp group and tool is tracked. Table 1 provides a representative data matrix for such monitoring and / or management:

[0075] Table 1: Representative Monitoring and Management of Clamps and Tools in the System

[0076]

[0077] For example, when evaluating the usage data in Table 1, the data management device of the system can issue a service alert, which can, for example, draw the user's attention to the fact that Tool 1 has been used for a total of 28,306 cycles and thus recommend a service inspection or maintenance. Another example can be based on the total usage cycles of one or more clamps. For example, Clamp 2 has been used for a total of 9,604 cycles and thus a service inspection or maintenance is recommended.

[0078] Specifically, and with further reference to Figure 7 , one or more tools such as Tools 50a and 50 are provided with controls, memory, and / or processing means, such as Figure 1 the controller 80 and memory 82 shown. One or more tool attachments such as clamp groups 10a, 10b, 10c, 10d, and / or 10e are provided with chips such as chip 86 for identifying and / or providing information related to the corresponding tool attachment. Tools such as 50a and 50b are also provided with communication means such as Figure 1 the device 84 shown in

[0079] for receiving information related to the corresponding tool attachment. At least one tool is configured to monitor and preferably count the usage cycles of the compression tool in the form of a compression operation. The tool is preferably also configured to monitor and count the usage cycles of each tool attachment used with it. For example, the tool is also configured to monitor and count the usage cycles of each of clamps 10a, 10b, 10c, 10d, and 10e. This data and information can be stored in the memory of the tool and / or transmitted to one or more other components such as cloud server 210, mobile devices 220a and / or 220b, and / or computer 230.

[0080] Figure 8It is a flowchart of an embodiment of another method according to the subject matter of the present invention. Specifically, a method 300 for a system for managing at least one tool and at least one tool attachment is provided. Method 300 includes one or more operations 302, wherein the usage cycle of the tool is counted and a cumulative total is provided. In operation 304, the tool cumulative total is compared with a tool usage warning value stored or otherwise provided at 306. In operation 308, if the tool cumulative total is greater than the tool usage warning value, a warning signal is issued in operation 320. Method 300 also includes one or more operations 310, wherein the usage cycle of the tool attachment is counted and a cumulative total is provided. In operation 312, the tool attachment cumulative total is compared with a tool attachment usage warning value stored or otherwise provided at 314. In operation 316, if the tool attachment cumulative total is greater than the tool attachment usage warning value, a warning signal is issued in operation 320.

[0081] Additional details regarding the use and incorporation of magnetic switches in the tool are as follows. Generally, one or more magnetic switches are placed along the cylinder of the clamping tool. The position of the magnetic switch is determined based on the stroke required for each clamp size. The controller inside the tool is capable of determining which magnetic switch (if multiple are installed) should be reached before shutting off the motor of the tool. In some embodiments, the magnetic switch is mechanically fixed to the cylinder at a position related to the stroke of the clamp. In a particular embodiment, multiple magnetic switches can be fixed to the cylinder at various positions related to the stroke of the clamp. The subject matter of the present invention includes a controller that is capable of reading the mechanical switch and stopping the advancement of the piston when the required distance of travel is reached. Also, the subject matter of the present invention includes a controller that is capable of reading an attachment such as a clamp using an electronic device and is capable of changing the required distance of travel based on the needs of the clamp.

[0082] Figure 9 is a schematic diagram of a hydraulic component 400 that can be used in a clamping tool 50. Component 400 includes a hydraulic cylinder 420 and a plunger 410 disposed within the cylinder 420. The plunger 410 includes one or more rollers 415. The hydraulic cylinder defines a first end 422 and a second end 424. The hydraulic component 400 also includes a plurality of magnetic switches, at Figure 9In the version shown, a plurality of magnetic switches includes three magnetic switches 496A, 496B, and 496C. Each of the magnetic switches is incorporated into the hydraulic cylinder 420, and particularly into the sidewall of the hydraulic cylinder 420. The magnetic switches 496A, 496B, and 496C are located between the ends 422, 424 of the hydraulic cylinder 420. When the plunger 410 is displaced relative to the hydraulic cylinder 420, one or more rollers 415 move relative to the magnetic switches 496A, 496B, and 496C. This movement and / or change in position of the rollers interacts with the magnetic switches and enables the clamping tool 50 and, for example, the controller 80 to directly sense or otherwise determine the position of the rollers 415, including the "initial" or closed position.

[0083] Figure 10 is a schematic hydraulic circuit of a hydraulic system 500 that uses the Figure 9 hydraulic assembly 400 shown in. The hydraulic system 500 includes a pump 510, a pressure sensor 520, a pressure relief valve 530, a tank or reservoir 540 that holds hydraulic fluid, a solenoid valve 550, and the previously mentioned hydraulic assembly 400.

[0084] Figure 11 is a schematic diagram of another hydraulic assembly 600 that can be used in the clamping tool 50. The assembly 600 includes a hydraulic cylinder 620 and a piston 610 disposed within the cylinder 620. The hydraulic cylinder defines a first end 622 and a second end 624. The hydraulic assembly 600 also includes a plurality of magnetic switches, and in Figure 11 the embodiment shown, the plurality of magnetic switches includes two magnetic switches 696A and 696B. Each of the magnetic switches is incorporated into the hydraulic cylinder 620, and particularly into the sidewall of the hydraulic cylinder 620. The magnetic switches 696A and 696B are positioned between the ends 622, 624 of the hydraulic cylinder 620. During displacement of the piston 610 relative to the hydraulic cylinder 620, the piston 610 moves relative to the magnetic switches 696A and 696B. This movement and / or change in position of the piston 610 interacts with the magnetic switches and enables the clamping tool 50 and, for example, the controller 80 to directly sense or otherwise determine the position of the piston 610 and / or the position of other components in the clamping tool 50 such as plungers and / or rollers.

[0085] Figure 12 is a schematic hydraulic circuit of another hydraulic system 700 that uses the Figure 11 hydraulic assembly 600 shown in. The hydraulic system 700 includes a pump 710, a pressure sensor 720, a pressure relief valve 730, a tank or reservoir 740 that holds hydraulic fluid, a solenoid valve 750, and the previously mentioned hydraulic assembly 600. In Figure 12In the system shown, the solenoid valve 750 is a double (2)-position solenoid valve 750.

[0086] In certain embodiments, pliers less than 1 to 1 / 4 inches have unique features, such as distinct tabs or red areas preferably extending outwardly on the side plates. When mounted on a tool, the tab is capable of pushing or actuating a switch (such as a micro limit switch) on the tool to release hydraulic pressure through a valve when a specific hydraulic pressure (such as 40 Mpa (24 kN)) is reached. For example, in Figure 2 a representative tab 99 extending outwardly from the side plates 14 or 16 of the pliers is shown. It should be understood that the subject matter of the present invention is not limited to pliers having the dimensions mentioned, nor to the specific representative tab 99, and includes a variety of outwardly extending members having other shapes and / or configurations that can be located in other areas of the pliers 10

[0087] Figures 13 to 16 Another aspect of the subject matter of the present invention is shown, wherein a set of pliers is identified by providing a physical feature sensed or otherwise recognized by the pressing tool, thereby providing information about the set of pliers to the pressing tool. Specifically, Figure 13 an embodiment of pliers 810 used in a pressing tool described in more detail herein is shown. The set of pliers 810 includes two opposing plier arms 812, each plier arm having a pressing profile at one end and generally having two cam profiles at the opposite end. The two plier arms 812 are held or retained between two T-shaped side plates 814, 816 by two side plate pins 818. The T-shaped side plates 814, 816 define holes 828 through which a plier pin, such as the aforementioned plier pin 70, passes to connect the pressing plier assembly 810 to the pressing tool. The pressing pliers 810 can be removed from the pressing tool by pulling out and removing the plier pin 70 from the hole 828. Additional features of the plier assembly 810 are as described previously in connection with the plier assembly 10.

[0088] In this embodiment, at least one of the side plates 814, 816 includes a physical feature sensed or otherwise recognized by the pressing tool or an associated component, thereby communicating information to the pressing tool, such information generally being about the pliers 810, such as its size, capacity, and / or configuration. This information is used to control and / or manage the operation of the pressing tool (such as its motor). In Figures 13 to 16 the embodiment, the physical feature is in the form of a protrusion 830. In the referenced drawing, the protrusion 830 extends rearwardly, i.e., towards the pressing tool that engages the pliers 810.

[0089] Figure 14Illustrated is a clamp set 810 and a representative assembly 840 incorporated into a pressing tool that not only senses or identifies the engagement of the clamp set with the pressing tool but also senses or identifies the engagement of the clamp set 810 due to contact with a protrusion 830. The sensing assembly 840 includes a movable guide rod 842, a movable ring 850, a microswitch or sensor 860, and an optional spring 870 disposed between the guide rod 842 and the ring 850. The guide rod 842 defines a distal end 844 and an opposite proximal end 846. When the clamp assembly 810 engages the pressing tool having the sensing assembly 840, the guide rod 842, particularly the distal end 844 of the guide rod 842, contacts the protrusion 830 of the clamp assembly 810. This engagement of the clamp set 810 with the pressing tool and the resulting contact between the protrusion 830 and the guide rod 842 displaces the ring 850, thereby actuating the microswitch 860. The actuation of the switch 860 is used as a control signal for the pressing tool and can be used to manage the operation of the pressing tool motor.

[0090] Figure 15 and Figure 16 Illustrated is the engagement of the clamp assembly 810 with the working or front end of the pressing tool 50. Specifically, Figure 16 is a schematic front view of the portions of the clamp assembly 810 and the pressing tool 50. Figure 15 is Figure 16 a schematic cross-sectional view of the assembly shown in Figure 15 and Figure 16 Further illustrated is the sensing assembly 840 and related components such as the guide rod 842, spring 870, ring 850, and switch 860.

[0091] The subject matter of the present invention includes a variety of sensing assemblies and is not limited to the specific sensing assembly 840 described herein. For example, the sensing assembly can include additional components and / or utilize components different from the guide rod 842 and / or the ring 850. Additionally, sensors other than or different from the microswitch 860 can be used.

[0092] Figure 17Shows another embodiment of the clamp 910 associated with the sensing assembly 840. The clamp 910 includes side plates having physical features in the form of recesses such as recess 930. In the referenced drawing, the recess 930 can be accessed from the rear, i.e., from the direction in which the clamp 910 engages the pressing tool. The clamp assembly 910 includes two opposing clamp arms 912, each clamp arm having a pressing profile at one end and generally two cam profiles at the opposite end. The two clamp arms 912 are held or retained between two T-shaped side plates 914, 916 by two side plate pins 918. The T-shaped side plates 914, 916 define a hole 928 through which a clamp pin such as the aforementioned clamp pin 70 connects the pressing clamp assembly 910 to the pressing tool. By pulling out and removing the clamp pin 70 from the hole 928, the pressing clamp 910 can be removed from the pressing tool. Additional features of the clamp assembly 910 are as described previously in connection with clamp assembly 10.

[0093] In this embodiment, at least one of the side plates 914, 916 includes physical features sensed or otherwise identified by the pressing tool or associated components, thereby communicating information to the pressing tool, the information generally regarding the clamp 910, such as its size, capacity, and / or configuration. This information is used to control and / or manage the operation of the pressing tool (e.g., its motor). In Figure 17 the embodiment, the physical feature is in the form of the recess 930.

[0094] As will be further appreciated with reference to Figure 17 it is understood that when the clamp 910 is engaged to a pressing tool including the sensing assembly 840, the distal end 844 of the guide rod 842 is received and engaged within the recess 930 of the clamp 910. The sensing assembly 840 is configured to distinguish or identify differences in the force applied to the switch 860 due to the guide rod 842 contacting the protrusion 830 of the clamp 810 or the recess 930 of the clamp 910. For example, a first set of clamps with typical or conventional side plates produces a specific force on the switch 860 when engaged in the pressure tool by the sensing assembly 840. If a second set of larger clamps is equipped with the aforementioned protrusion 830, a greater force can be produced on the switch 860. Additionally, another set of clamps having the previously described recess 930, i.e., a third set of clamps smaller than the first set of clamps, can produce a smaller force on the switch 860. The different forces applied to the switch 860 enable the sensing assembly 840 and / or associated electronics to identify a specific clamp set or characteristics of the clamp set.

[0095] The subject matter of the present invention includes various sets of jaws and the geometry and configuration of a sensing assembly and / or an electronic device for communicating information or characteristics of the set of jaws to a pressing tool. For example, a set of jaws can utilize a plurality of protrusions and / or recesses or indentation areas. The protrusions, recesses, and / or indentation areas can have different shapes and / or sizes. In such a version, the switch of the sensing assembly can include a plurality of switches or sensors to divide a range of potential sets of jaws into multiple groups. In such a version, a pressing tool utilizing such a sensing assembly can be configured to generate different and / or multiple forces.

[0096] Figure 18 Another set of jaws 1010 according to the subject matter of the present invention is shown. The set of jaws 1010 includes two opposing jaw arms 1012, each jaw arm having a pressing profile at one end and generally two cam profiles at the opposite ends. The two jaw arms 1012 are held or retained between two T-shaped side plates 1014, 1016 by two side plate pins 1018. The T-shaped side plates 1014, 1016 define a hole 1028 through which a jaw pin such as the previously described jaw pin 70 passes to connect the pressing jaw assembly 1010 to the pressing tool. By pulling out and removing the jaw pin 70 from the hole 1028, the pressing jaw 1010 can be removed from the pressing tool. Additional features of the jaw assembly 1010 are as previously described in connection with the jaw assembly 10.

[0097] In this embodiment, at least one of the side plates 1014, 1016 includes a plurality of physical features that are sensed or otherwise identified by the pressing tool or an associated component to communicate information to the pressing tool, the information generally regarding the jaws 1010, such as its size, capacity, and / or configuration. This information is used to control and / or manage the operation of the pressing tool (e.g., its motor). In Figure 18 the embodiment, the physical features are in the form of a first protrusion 1030, a second protrusion 1032, and a recess 1034 defined between the first protrusion 1030 and the second protrusion 1032. In the referenced drawings, the protrusions 1030, 1032 extend rearwardly, i.e., towards the pressing tool that engages the jaws 1010. And, as previously described, the recess 1034 is accessible from the rear.

[0098] As an alternative or supplement to switch 860 or its variants of sensing component 840, a wide variety of sensors can be used. For example, a position sensor can be used to determine if there is a target. For example, position sensor targets can include, but are not limited to: identifying the start position of clamping; identifying the final position of clamping; and / or identifying the cam position with an increased stress level. One or more strain sensors can be used to determine or measure the strain borne by the clamp arms and convert the measurement or evaluation result into one or more output signals. In addition, a position sensor can sense the position of the object to be measured and convert it into a sensor capable of outputting a signal. For example, there are two types of position sensors: contact type and proximity type. Regarding contact sensors, the contact of the contact sensor is actuated by the contact between two objects, such as a travel switch and a two-dimensional matrix position sensor. A proximity sensor or switch refers to a switch that can emit an "action" signal when an object approaches a set distance without direct contact with the object. There are many types of proximity switches, mainly electromagnetic, photoelectric, differential transformer, eddy current, capacitive, reed switch, Hall type, etc. A photoelectric sensor switch can be used. A distance sensor can be used. The distance sensor can evaluate the distance from the clamp set to the sensor. The distance sensor can use laser technology, ultrasonic technology, infrared technology, and / or Hall effect magnetic field technology. Suitable sensors can be obtained from many commercial suppliers, such as but not limited to such sensors obtained from Baumer Ltd., South Windsor, Connecticut, USA.

[0099] One or more switches and / or one or more sensors of the sensing component can be incorporated into and / or located at various different positions in the clamping tool. Figure 19 Another embodiment of clamp 1110 engaged with clamping tool 50 is shown. Clamp set 1110 includes two opposing clamp arms 1112, each clamp arm having a clamping profile at one end and generally two cam profiles at the opposite end. The two clamp arms 1112 are held or retained between two T-shaped side plates 1114, 1116 by two side plate pins 1118. The T-shaped side plates 1114, 1116 define holes 1128 through which a clamp pin, such as clamp pin 70 described above, passes to connect the clamping clamp assembly 1110 to the clamping tool. By pulling out and removing the clamp pin 70 from the hole 1128, the clamping clamp 1110 can be removed from the clamping tool 50. Other features of clamp assembly 1110 are as described previously in connection with clamp assembly 10.

[0100] The pressing tool 50 includes a sensing assembly 840 having a switch 860. The switch 860 is located within the cylinder head region of the pressing tool 50 so as to be relatively close to the side plate 1114 of the jaw set 1110. The protrusion 1130 of the side plate 1114 is used to directly contact the switch 860 and actuate the switch. This arrangement eliminates other components of the sensing assembly 840 such as the guide rod 842, the ring 850, and the spring 870.

[0101] The subject matter of the present invention also includes a sensing assembly for use in combination with jaws and jaw sets that do not have side plates. For example, instead of using one or more physical features in a side plate, one or both jaws can include a particular one or more physical features that are used by a sensing assembly incorporated in the pressing tool to convey information about the jaw or jaw set. Figure 20 and 21 An embodiment of a jaw 1210 for use in the pressing tool described herein is shown. The jaw 1210 does not have a side plate. The jaw 1210 includes two opposing jaw arms 1212, each jaw arm having a pressing profile at one end and generally having two cam profiles at the opposite end. The pressing profile is shown as 1220. The cam profiles are shown as 1230. Each of the jaw arms 1212 defines a hole 1228 through which a jaw pin such as the previously described jaw pin 70 passes to connect the jaw assembly 1210 to the pressing tool.

[0102] In this embodiment, at least one of the jaw arms 1212 includes a physical feature that is sensed or otherwise recognized by the pressing tool or an associated component to convey information to the pressing tool, such information typically being about the jaw 1210, such as its size, capacity, and / or configuration. This information is used to control and / or manage the operation of the pressing tool (such as its motor). In Figures 20 to 21 the embodiment, the physical feature is in the form of a protrusion 1240. In the referenced drawings, the protrusion 1240 extends laterally outward from the face or side surface of the jaw arm 1212.

[0103] In the specific embodiments described herein and shown in Figure 20 and Figure 21 the protrusion 1240 is in the form of a circular or arcuate rib. The construction, shape, curvature, height, and / or position of the protrusion on the jaw arm can be used to transmit information to the sensing assembly. Generally, the sensing assembly will employ the same or similar components as the previously described sensing assembly 840. See Figure 17 , once the jaw 1210 is engaged in the pressing tool, contact will occur between the protrusion 1240 and the distal end 844 of the guide rod 842. In many versions, the contact occurs at the distal end 844 of the guide rod 842 or as Figure 19Between the shown microswitch 860 and the rearwardly oriented face 1242 of the projection 1240. It will be understood that the projection 1240 and / or its face 1242 can constitute a physical feature for communicating information to the sensing assembly. The subject matter of the present invention also includes versions of the clamp assembly or clamp set without side plates, wherein the physical feature is in the form of a projection such as a rearwardly extending protrusion, a recess, and combinations thereof. The recess can be accessed from the rear.

[0104] An alternative provided by the subject matter of the present invention is a tool that detects full clamp closure and, once full clamp closure is detected, terminates the pressing cycle. Although such a tool can help extend the life of the clamp or reduce the weight of the clamp, since it is not possible to collect data on specific clamps, the tool cannot track the usage history of individual clamps.

[0105] The pressing tool according to the subject matter of the present invention can include a variety of alternatives. The pressing tool can include a pressure sensor. The pressing tool can include an electronic circuit, one or more controllers, a memory, and associated components to record and / or store information about different sizes of fittings and a hydraulic requirement data matrix. The pressing tool can include an electromagnetic switch to release a hydraulic valve. The clamp can have unique features on a part (e.g., a side plate) to indicate a specific size or configuration. The unique features on the side plate can signal the pressing tool, for example, by turning on or off a plurality of microswitches. Signals from the switches or sensors can communicate with the electronic circuit, controller, memory, and associated components to notify a magnetic switch to release the hydraulic valve when a required hydraulic pressure, for example, 40 Mpa (which is equal to a required force of, for example, 24 kN), is reached. Various clamps can be classified into specific groups, for example, clamps below 1 to 1 / 4 inches that require 24 kN, and clamps from 1 inch to 2 inches that require 32 kN. The default force of the pressing tool can be a relatively high force, for example, 32 kN (53 Mpa). The pressing tool can include a pressure sensor. The pressing tool can include an electromagnetic switch to release a hydraulic valve. Clamps below 1 to 1 / 4 inches can have unique features, such as a dedicated tab or a red area on the side plate, and when installed on the tool, the dedicated tab can push a micro limit switch on the tool MCU to release the valve when a lower hydraulic pressure (e.g., 40 Mpa (24 kN)) is reached.

[0106] The tools and clamps provide the following various advantages and benefits. The clamps can be divided or classified into multiple groups, such as two or three groups. For example, clamps below 1 to 1 / 4 inches that require 24 kN, and clamps from 1 inch to 2 inches that require 32 kN. The default force of the pressing tool is a relatively high force, such as 32 kN (53 Mpa). The pressing tool can include a pressure sensor. The pressing tool can include an electromagnetic switch to release the hydraulic valve. Clamps below 1 to 1 / 4 inches can have unique features, such as a dedicated tab or a red area on the side plate. When installed on the tool, the dedicated tab can push the micro limit switch on the tool's electronic circuit, controller, memory, and related components to release the valve when a lower hydraulic pressure is reached (e.g., 40 Mpa (24 kN)).

[0107] The subject system of the present invention includes one or more tools that have electronic data storage devices such as memory 82, electronic control circuits such as controller 80, and communication devices such as device 84 and / or interconnectivity device 85. Generally, these tools are electric or at least include electronic controls. In many embodiments, the tool is a handheld tool, but the subject of the present invention includes other tools or tool systems such as fixed or non-mobile tool systems (e.g., floor-standing devices or movable or bench-top tools). One or more tools can be used with a cloud server and a mobile device. Non-limiting examples of the tool include pressing tools, crimping tools, inspection or remote observation systems, positioning devices, rotary power tools including drills, grinders, impact tools, electric wrenches, expansion tools, forming or shaping tools, table saws, circular saws, miter saws, etc. The subject of the present invention encompasses a wide variety of tools. And, although clamps, clamp groups, or clamp assemblies are used as examples of tool attachments, it should be understood that the subject of the present invention is not limited to clamps but includes a wide variety of other tool attachments.

[0108] The electronic data storage devices typically incorporated into the tools can take the form of known data storage formats including flash memory components. The data storage devices can also include or exist in the form of memory cards, disk or drive components, data cartridges, or components such as ROM or RAM memories, as well as peripheral data storage components.
