Description

Technical Field

[0001] The invention relates to the technical field of automobile spring leaf stamping, in particular to an automatic stamping system for automobile brake system spring leaves. Background Art

[0002] Automobile spring leaf is a mechanical part that uses elasticity to work and is a spare part commonly used in automobile braking systems.

[0003] Currently, automobile spring leaves are mainly produced using stamping machines (also known as bending machines). During stamping, a metal strip is fed into a stamping die and formed by stamping. However, the stamping efficiency of existing stamping machines is not high. For automobile spring leaves with special structures, it is usually necessary to use multiple stamping machines to complete the production.

[0004] In addition, during stamping, due to the influence of the working environment, some metal debris will remain on the material. Currently, there is a lack of means to clean the metal belt during the loading process, which will inevitably affect the stamping effect of the spring leaf.

[0005] In summary, the above defects need to be improved. Summary of the Invention

[0088] S6: When the electromagnet is energized, the magnetic valve plate is repelled and the air outlet is opened. The driving plate is controlled to descend by the fourth return spring, and the gas in the driving chamber is squeezed into the air injection chamber. When the driving plate descends, the control nut and the screw cooperate to drive the cleaning body to rotate through the driving shaft to complete the cleaning of the metal strip.

[0089] S7: After step S6 is completed, return to step S1.

[0090] Preferably, the method further includes an impurity recovery method, wherein the impurity recovery method includes:

[0091] During steps S6-S7, the air jet hole generates an air flow toward the dust inlet when the air is ejected, and blows the impurities toward the dust inlet;

[0092] At the same time, the piston body moves, causing negative pressure to form in the first dust suction chamber and the second dust suction chamber, and sucking dust through the dust inlet hole to complete impurity recovery.

[0093] The present invention has at least the following beneficial effects:

[0094] 1. The punching device of the present invention can be used to punch metal strips at multiple angles. Therefore, when producing special-shaped automobile spring leaves, there is no need to replace multiple punching devices for punching. Therefore, the production can be completed after one round of punching, thereby improving production efficiency.

[0095] 2. The feeding device of the present invention can clean the surface of the metal strip during the feeding process, thereby ensuring that the metal strip is not affected by foreign matter on the surface of the metal strip during stamping, thereby ensuring the stamping effect;

[0096] 2.1 The feeding device of the present invention utilizes a clamping assembly to clean the metal strip without affecting the feeding efficiency. That is, when the clamping device is close to the stamping device, it drives the metal strip to move toward the stamping device, and when the clamping device moves away from the stamping device (the stamping device is performing stamping work), the metal strip is cleaned.

[0097] 3. When cleaning the metal strip, the feeding device of the present invention utilizes the pneumatic components and the airflow control components to cooperate to complete the cleaning, impurity recovery and self-cleaning of both sides of the metal strip;

[0098] 3.1 Before cleaning, the air flow control assembly sends air into the drive cavity of the clamping assembly. During cleaning, the clamping assembly moves closer to the air flow control assembly and discharges the air in the air supply cavity, thereby discharging the air in the drive cavity. The nut on the drive rod cooperates with the screw on the drive shaft to drive the cleaning body to rotate and clean the metal belt;

[0099] 3.2 During impurity recovery, based on the process in 3.1, the gas discharged from the air supply chamber and the drive chamber can transport the impurities generated by cleaning to the dust collection chamber, where they are sucked in, completing the impurity recovery. Furthermore, the present invention can also remove the filter structure and clean the impurities in the dust collection chamber. In addition, the dust collection chamber of the present invention can pre-feed air into the drive chamber of the clamping assembly when the clamping assembly drives the metal strip toward the stamping device, in preparation for process 3.1.

[0100] 3.3 During self-cleaning, that is, the process in which the dust suction chamber sends the airflow into the driving chamber of the clamping assembly (that is, the process in which the clamping device controls the loading of the metal strip), the cleaning body is controlled by the nut and the screw to rotate in the opposite direction to the process in 3.1, thereby completing the dust removal and self-cleaning. This process is carried out when the metal material is loaded, and is not at the same stage as the cleaning work of the metal strip, thereby making the cleaning and self-cleaning purposes independent of each other.

[0101] 4. In addition, the present invention is provided with a safety chamber. The safety chamber can be used to form a negative pressure in the safety chamber when the clamping assembly cleans the metal strip (that is, when the air supply chamber supplies air to the safety chamber). In this way, when an electromagnetic failure occurs, the airflow entering the exhaust chamber can also better lift the movable body, thereby separating the pressing body from the metal strip, thereby avoiding wear on the metal strip during the cleaning process (that is, the process of the clamping assembly moving away from the stamping device), thereby playing a safety role.

[0102] In addition, other advantages of the present invention will be demonstrated in the embodiment of the present invention, thereby making the beneficial effects of the present invention more significant. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0119] Example 1

[0120] like Figure 1-7 As shown, the present invention discloses an automated stamping system for automobile brake system spring leaves, comprising a stamping device 1, a loading device 2 and a unloading device 3.

[0132] Among them, the slide 111 is provided with a first mounting groove for the stamping die to be disassembled and connected, and a number of fixing studs 117 are provided in the first mounting groove, and each fixing stud 117 is equipped with a nut structure 118, that is, the stamping die is provided with a mounting hole for the fixing bolt 117 to pass through, so as to fix the stamping die on the slide.

[0133] In this embodiment, the driving assembly includes:

[0134] The driving cam 120 is rotatably disposed at the transmission area 110b;

[0135] The transmission wheel 121 (located on the back of the frame 10) is connected to the driving cam 120 through a rotating shaft;

[0136] The transmission belt 122 is connected between the transmission wheels 121;

[0137] Any transmission wheel 121 can be driven to rotate by the motor and control the driving cam 120 to rotate. When the driving cam 120 rotates, it cooperates with the return spring to control the slide 111 to reciprocate on the slide rail.

[0138] In this embodiment, the unloading device 3 is composed of a cylinder 30 and a unloading shaft 31 arranged on the back of the frame 10. The unloading shaft 31 is controlled by the cylinder 30, and the unloading shaft 31 passes through the frame 10. A chassis 32 for installing the cylinder 30 is provided on the back of the frame 10.

[0139] In this embodiment, the stamping die is composed of a first die 100a, a second die 100b, a third die 100c, a fourth die 100d and a fifth die 100e, wherein a detachable pressing die 100f is further provided on the frame 10, and the fifth die 100e is controlled to slide and is arranged on both sides of the pressing die 100f, and the pressing die 100f has a step surface 100g (that is, the pressing die is composed of a substrate 100h and a main body 100i installed on the substrate 100h, and the main body 100i and the substrate 100h have a height difference, which also forms the step surface 100g mentioned in this embodiment, and the step surface 100g is the end face of the substrate 100h away from the frame 10, and the fifth die 100e can slide on both sides of the main body 100i).

[0140] refer to Figure 1-7 , the stamping principle of this embodiment is:

[0141] During stamping, the drive assembly starts and controls the rotation of each drive cam through the transmission wheel (in other embodiments, the combination of the transmission wheel and the transmission belt of this embodiment can also be replaced by the transmission cooperation of a sprocket and a chain), and uses each drive cam to successively control each stamping die to approach the pressing die head to complete the stamping of the metal strip. In more detail:

[0142] refer to Figure 1-2 as well as Figure 6 First, this embodiment controls the third die head 100c and the fifth die head 100e to approach each other, and sends the metal strip between the pressing die head and the third die head in the feeding device, and is clamped by the pressing die head and the third die head. At the same time, the fifth die head descends and performs the first punching on the metal strip, which can complete the process of the metal strip from the first form to the second form. Subsequently, in the process of the pressing die head and the third die head clamping the metal strip, the first die head, the second die head and the fourth die head respectively punch the metal strip for the second time, completing the process of the metal strip from the second form to the third form, thereby completing the stamping.

[0143] After the stamping is completed, the fourth die head is used to cut the metal strip. After cutting, the third die head carrying the spring sheet descends, and the cylinder of the unloading device is used to control the movement of the unloading shaft to push the spring sheet on the third die head away, thereby completing the stamping.

[0144] refer to Figure 2 In this embodiment, the moving assembly controls the movement of the stamping die by relying on the cooperation of the return spring and the driving cam to realize the reciprocating movement of the moving assembly, that is, the cam controls the stamping die on the moving assembly to approach the metal strip and stamp, and the return spring controls the separation of the moving assembly. In this embodiment, the stamping die on the moving assembly can be replaced to match the production of spring sheets of different shapes, so there is no need to replace different stamping machines to produce spring sheets.

[0145] Example 2 is different from Example 1 in that:

[0146] like Figure 8 As shown, in this embodiment: the feeding device 2 includes:

[0147] Clamping assembly 20;

[0148] An airflow control assembly 21 is provided on any side of the clamping assembly 20;

[0149] A reciprocating drive assembly, used to control the reciprocating motion of the clamping assembly 20;

[0150] The clamping assembly 20 and the airflow control assembly 21 form a feeding channel for the metal strip to move;

[0151] When the reciprocating drive assembly controls the clamping assembly 20 to move away from the punching device 1 , the clamping assembly 20 releases the metal strip 101 and wipes the metal strip 101 ;

[0152] When the reciprocating drive assembly controls the clamping assembly 20 to move toward the punching device 1 , the clamping assembly 20 fixes the metal strip 101 and drags the metal strip 101 toward the punching device 1 .

[0153] In this embodiment, the reciprocating assembly is a screw structure, which is composed of at least a screw 40, a screw bearing seat 41 and a screw motor 42. The clamping assembly 20 is connected to the screw bearing seat 41 and is slidably arranged on the mounting plate 43, and the mounting plate 43 is fixedly arranged on the frame 10.

[0154] In this embodiment, the clamping assembly 20 includes:

[0155] The clamping body 200 has a feeding channel 201 that passes through the clamping body 200 and allows the metal strip 101 to pass through;

[0156] The second mounting groove 202 is formed on the cavity walls on both sides of the feeding channel 201;

[0157] a pneumatic assembly mounted in the second mounting slot 202 and having a working end that can be controlled by the electromagnet 203 and / or the airflow control assembly 21;

[0158] When the electromagnet 203 is energized or the air flow control assembly 21 supplies air to the pneumatic assembly, the working end of the pneumatic assembly forms a wiping end and wipes the metal strip 101 when the clamping body 200 moves;

[0159] When the electromagnet 203 is powered off and the air flow control assembly 21 stops supplying air, the working end of the pneumatic assembly forms a clamping end and clamps the metal strip 101 to move when the clamping body 200 moves.

[0160] In this embodiment, the pneumatic assembly includes:

[0161] The pneumatic body 50 is installed in the second installation groove 202 and has a pneumatic cavity;

[0162] The movable body 51 is installed in the pneumatic body 50 (in the pneumatic cavity) via a third return spring 52 , and divides the pneumatic cavity into an exhaust cavity and a safety cavity 54 . The safety cavity 54 has an air flow opening 55 that passes through the pneumatic body 50 .

[0163] an air inlet 56 provided on the pneumatic body 50 and communicating with the exhaust chamber;

[0164] The cleaning body 57 is connected to the movable body 51 via a lifting shaft 57a;

[0165] The cleaning body 57 is provided with a plurality of exhaust pipes 58, one end of which can penetrate into the exhaust cavity. The electromagnet 203 is provided on the pneumatic body 50. When the electromagnet 203 is energized, the movable body 51 is attracted to move closer to the electromagnet 203 and the air inlet 56 is opened.

[0166] When the air flow control assembly 21 supplies air to the safety chamber 54 and the exhaust chamber through the air flow port 55 and the air inlet 56 respectively, negative pressure is formed in the safety chamber 54 and the air flow from the air inlet 56 into the exhaust chamber assists in lifting the movable body 51 .

[0167] In this embodiment, the air flow control components may be different air pumps for controlling air intake to the air inlet and the air flow outlet respectively.

[0168] refer to Figure 1 and Figure 8 , the principle of this embodiment is:

[0169] The movement of the clamping body of this embodiment is controlled by a screw structure. When the clamping body moves toward the punching device, the electromagnet is de-energized and the air pump stops supplying air to the air inlet and the air flow port. At this time, the metal strip in the feeding channel is clamped by the cleaning body and driven by the clamping body toward the punching device for feeding;

[0170] When the clamping body moves away from the stamping device, the electromagnet is energized and the air pump supplies air to the air inlet and the air flow port. The electromagnet is energized and attracts the movable body to move closer to the electromagnet. Therefore, the cleaning body is driven to no longer clamp the metal strip, but only contact the metal strip. Therefore, when the clamping body moves, the metal strip can be wiped and the airflow discharged from the exhaust chamber can be used to clean the metal strip.

[0171] It is worth noting that the airflow passing through the safety cavity can dissipate the heat of the electromagnet, and when the electromagnet fails, the airflow flowing in the safety cavity forms a negative pressure, so that the airflow entering the exhaust cavity from the air inlet can lift the movable body, thereby causing the cleaning body to lose its clamping force on the metal belt, thereby playing the role of insurance and heat dissipation.

In other words, the magnetism of the magnetic valve disc 86 is opposite to the magnetism generated by the electromagnet when it is energized. (In other embodiments, the magnetic valve disc can also be arranged to be attracted by the electromagnet. It is only necessary to change the position of the fifth return spring so that the fifth return spring is located between the magnetic valve disc and the electromagnet.)

[0206] A first air pipe 91 is connected between the exhaust nozzle 7 d and the driving chamber 80 , and a one-way valve 215 is provided on the first air pipe 91 .

[0207] In this embodiment, a pressing body 93 is mounted at the bottom of the second rack 64. The pressing body 93 is formed with an air jet chamber 93a and an air jet hole 93b communicating with the air jet chamber 93a. The air jet chamber 93a is communicated with the air outlet 85 via a second air pipe 92 (in this embodiment, the air flow outlet at the exhaust end of the fuse chamber can also be communicated with the air jet chamber via an air pipe).

[0208] The inner wall of the pressing body 93 is formed with a guide surface for guiding impurities to flow toward the dust inlet 7c. The jet holes 93b jet toward the guide surface or the dust inlet, and when the jet holes 93b jet, an airflow flowing toward the dust inlet is formed on the guide surface.

[0209] In this embodiment, in order to realize the exhaust of the exhaust chamber 53 and omit the exhaust pipe, an air outlet chamber 94 is provided on the driving shaft and the rotating shaft (that is, the air outlet chamber 94 realizes the function of the exhaust pipe), and the air outlet chamber is communicated with the exhaust chamber 53, and a cleaning cotton 57b is provided on the cleaning body 57 (the cleaning cotton is bent, refer to Figure 14 ), an air nozzle 57c is provided on the cleaning body 57, and the air nozzle 57c is communicated with the air outlet cavity 94 and is used to blow air to the cleaning cotton 57b and blow impurities generated during the cleaning process of the cleaning cotton toward the drainage surface.

[0210] refer to Figure 9-14 , the principle of this embodiment is:

[0211] Feeding principle: reference Figure 9 、 Figure 11-12 During loading, when the screw structure controls the clamping body to move toward the stamping device, the clamping body moves and drives the piston plates in each air supply chamber to move, and forms a negative pressure in the air supply chamber, thereby causing each air supply to inhale. During this process, the electromagnet is powered off, and the clamping body is driven by the movable body and the third return spring to clamp the metal strip and drive the metal strip toward the stamping device, thereby completing the loading.

[0212] Cleaning principle: reference Figures 9-14 During cleaning, the screw structure controls the clamping body to move away from the punching device. During this process, the electromagnet is energized to generate magnetism and attract the movable body to rise. At the same time, the driving wheel cooperates with the first rack and the second rack respectively, so that the pressing body loses its pressure on the metal strip and the cleaning cotton on the cleaning body contacts the metal strip. During the movement of the clamping body, the cleaning cotton on the cleaning body is used to clean the metal strip, thereby completing the cleaning work.

[0213] Furthermore, during the metal strip feeding process, the exhaust nozzle of the dust suction chamber discharges gas and inflates the driving chamber, causing the driving plate to control the nut to rise. When the cleaning body contacts the metal strip and cleans it, the electromagnet is energized and controls the magnetic valve to open the air outlet. The gas in the driving chamber is discharged into the air jet chamber, and the driving plate is driven down by the fourth return spring, while controlling the nut to descend. Under the cooperation of the nut and the screw, the driving shaft is driven to rotate, and the cleaning body is driven to rotate by the rotating shaft. The cleaning body can improve the cleaning effect of the metal strip in a rotating posture.

[0214] Furthermore, during the process of the cleaning body rotating and cleaning the metal strip (which is also the process of the clamping body moving away from the stamping device), the gas in the air supply chamber is squeezed out and respectively sent into the safety chamber and exhaust chamber of different pneumatic components (that is, the first air supply chamber and the second air supply chamber above the feeding channel respectively correspond to the safety chamber and exhaust chamber of the pneumatic component above the feeding channel. Similarly, the same is true for the air supply chamber and the pneumatic component below the feeding channel). The airflow entering the safety chamber is sent into the air injection chamber after dissipating the heat for the electromagnet. The gas entering the exhaust chamber enters the air injection nozzle of the cleaning body through the air outlet chamber on the driving shaft and the rotating shaft. Figure 14 After the cleaning cotton on the cleaning body cleans the metal belt, the airflow ejected from the air nozzle can blow the impurities to the drainage surface, completing the cleaning of the metal belt;

[0215] Furthermore, when impurities enter the drainage surface, the airflow entering the jet cavity is ejected from each jet hole (refer to Figure 14 ), the airflow ejected from the air jet hole flows along the guide surface and blows the impurities toward the dust collection chamber. When the clamping body moves away from the punching device, the piston body in the dust collection chamber moves and forms a negative pressure in the dust collection chamber, and the impurities are sucked into the air intake area of ​​the dust collection chamber from the air inlet, completing the recovery of the impurities;

[0216] Furthermore, when impurities enter the dust suction chamber, the impurities in the dust suction chamber can be cleaned when the filter structure is disassembled. The filter structure of this embodiment can filter out the impurities entering the dust suction chamber when the dust suction chamber supplies air to the driving chamber, thereby concentrating the impurities in the air intake area.

[0217] Self-cleaning principle: It is carried out simultaneously with the feeding principle, that is: during the feeding process, the dust suction chamber will send the airflow into the driving chamber, the electromagnet is powered off at this time, the movable body moves close to the cleaning body, and uses the driving gear and rack structure to control the cleaning body to rise and separate from the metal belt. Then the gas entering the driving chamber uses the driving plate to control the nut and screw structure to cooperate and drive the rotating shaft to reverse (reversal is the direction opposite to the rotation direction of the rotating shaft during the cleaning process), and throw away the impurities. The thrown impurities are located on the metal belt between the clamping body and the airflow control component. The metal belt in this interval will be cleaned during the cleaning process, so it does not affect the feeding.

[0218] It should be noted that:

[0219] In this embodiment, according to actual conditions, multiple groups of clamping components and airflow control components can be provided to enhance the cleaning of the metal strip.

[0220] To ensure the sealing effect, sealing rings may be provided at the connection positions between the components of this embodiment according to actual conditions.

[0221] Example 4

[0222] This embodiment provides a method for using a loading device, which uses the loading device as in Example 3, including a loading method, a metal strip cleaning method, and an impurity recovery method.

[0223] Among them, the loading method includes:

[0224] S1: In the electromagnet power-off mode, the pressing body on the second rack clamps the metal belt;

[0225] S2: Use the reciprocating drive assembly to control the clamping assembly to move toward the stamping device and pull the metal strip toward the stamping device;

[0226] Among them, when the clamping assembly moves toward the stamping device in step S2, negative pressure is formed in the air supply chamber and air is taken in. At the same time, the piston body moves and squeezes the gas in the first dust suction chamber and the second dust suction chamber into the driving chamber, and the cleaning body is reversed by controlling the nut and screw to remove dust.

[0227] Cleaning methods include:

[0228] S3: In the electromagnet power-on mode, the clamping body on the second rack is moved away from the metal belt, and the cleaning body on the lifting body is controlled to contact the metal belt through the driving gear;

[0229] S4: Using the reciprocating drive assembly to control the clamping assembly to move away from the stamping device, at this time, the gas in the gas supply chamber in step S2 is squeezed out and sent to the safety chamber and the exhaust chamber respectively;

[0230] S5: The airflow in the fuse chamber dissipates the heat of the electromagnet and then discharges it, forming a negative pressure in the fuse chamber; the gas entering the exhaust chamber is discharged through the exhaust pipe and flows from the center of the cleaning body to the edge of the cleaning body, carrying impurities to the drainage surface;

[0231] S6: When the electromagnet is energized, the magnetic valve plate is repelled and the air outlet is opened. The driving plate is controlled to descend by the fourth return spring, and the gas in the driving chamber is squeezed into the air injection chamber. When the driving plate descends, the control nut and the screw cooperate to drive the cleaning body to rotate through the driving shaft to complete the cleaning of the metal strip.

[0232] S7: After step S6 is completed, return to step S1.

[0233] Impurity recovery methods include:

[0234] During steps S6-S7, the air jet hole generates an air flow toward the dust inlet when the air is ejected, and blows the impurities toward the dust inlet;

[0235] At the same time, the piston body moves, causing negative pressure to form in the first dust suction chamber and the second dust suction chamber, and sucking dust through the dust inlet hole to complete impurity recovery.

[0236] When using this embodiment, please note that:

[0237] The suction process of the air supply chamber in the feeding method must precede the cleaning method, that is, the air supply chamber must be inflated before cleaning, so that the safety chamber can be used to protect the metal strip during the cleaning process.

[0238] This embodiment has the advantage of timely heat dissipation of the electromagnet, that is, during the loading process, the electromagnet is powered off, and the heat generated by the non-operating electromagnet is low, and at this time no gas is passed into the fuse cavity. During the cleaning process, the electromagnet is powered on and begins to generate heat. At this time, gas is passed into the fuse cavity, so timely heat dissipation can be achieved.

[0239] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
