Description

Technical Field

[0001] This utility model relates to the field of fastener forming technology, specifically to a feeding assembly and fastener forming equipment. Background Technology

[0002] Fastener forming equipment can process wire into parts such as screws and rivets. Some fastener forming equipment has multiple production modes. When switching production modes, the wire feeding method must also be adjusted accordingly to ensure that the current feeding chute is aligned with the downstream wire inlet hole. If the feeding chute is not positioned accurately, the wire will be fed in at an angle, resulting in a decrease in part quality.

[0003] Therefore, the relevant technologies require the position of the feeding component to be calibrated every time the production mode is switched, which is a cumbersome operation and reduces the production efficiency of the fastener forming equipment. Utility Model Content

[0004] In view of this, the present invention provides a feeding component and a fastener forming equipment to solve the problem that the process of changing the feeding method of the feeding component is cumbersome.

[0005] In a first aspect, this utility model provides a feeding assembly, including a mounting base, multiple rotating shafts, and multiple feeding wheels. The multiple rotating shafts are arranged in pairs on the mounting base in a first direction. Each rotating shaft is rotatable along its own axis. Each rotating shaft includes a first positioning step. The multiple feeding wheels are detachably sleeved on the rotating shaft. Each feeding wheel includes a first feeding groove and a second feeding groove arranged circumferentially at intervals. Each feeding wheel includes a first positioning surface and a second positioning surface. The first positioning surface is located at one end of the feeding wheel in the axial direction, and the second positioning surface is located at the other end of the feeding wheel in the axial direction. The feeding wheel can abut against the first positioning step through the first positioning surface or the second positioning surface to switch the feeding mode of the feeding wheel.

[0006] Beneficial effects: The feeding assembly is used to feed wire. The wire is clamped between two pairs of feeding rollers and conveyed downstream by the rotation of the feeding rollers. The feeding rollers can be positioned and installed through the first positioning surface or the second positioning surface, thereby switching between two different feeding methods. When it is necessary to change the feeding method, it is only necessary to remove the feeding rollers, change the installation direction, and make the different positioning surfaces abut and position the first positioning step. There is no need to recalibrate the position. Therefore, the feeding assembly can simplify the operation steps, improve the efficiency of changing the feeding method, and help improve the production efficiency of fastener forming equipment.

[0007] In one alternative implementation, the diameter of the first feeding trough is greater than the diameter of the second feeding trough; and / or, the number of the first feeding troughs is greater than the number of the second feeding troughs.

[0008] Beneficial effects: The first and second feeding troughs are designed differently to meet the needs of the feeding assembly to switch between two different feeding methods.

[0009] In one alternative implementation, the feed roller and the rotating shaft are clearance-fitted.

[0010] Beneficial effects: The clearance fit installation method makes it easier to disassemble and assemble the feeding wheel, further improving the efficiency of changing the feeding method and helping to improve the production efficiency of fastener forming equipment.

[0011] In an alternative embodiment, a threaded fastener is further included, disposed at the end of the rotating shaft, the threaded fastener pressing the feed wheel against the first positioning step.

[0012] Beneficial effects: Threaded fasteners reliably press the feed wheel, thereby ensuring that the positioning effect of the feed wheel meets the requirements. At the same time, threaded fasteners are easy to install and remove, which can further improve the efficiency of changing the feeding method and help improve the production efficiency of fastener forming equipment.

[0013] In one optional embodiment, the rotating shaft includes a first keyway, the feeding wheel includes a second keyway, and the feeding assembly further includes a connecting key, which is disposed in the first keyway and the second keyway.

[0014] Beneficial effects: The feeding wheel and the shaft are connected by a key, which allows for smooth torque transmission even with a clearance fit, preventing slippage between the feeding wheel and the shaft and ensuring that the feeding wheel stably feeds out the wire.

[0015] In one alternative embodiment, two pairs of the rotating shafts form a group of the rotating shafts, and multiple groups of the rotating shafts are spaced apart in a second direction, which is perpendicular to the first direction.

[0016] Beneficial effects: By setting multiple sets of rotating shafts, the feeding assembly can use multiple sets of feeding wheels to feed simultaneously. The multiple sets of feeding wheels can calibrate the posture of the wire, so that the wire is conveyed straight along the second direction, thereby further improving the feeding quality of the feeding assembly and helping to improve the product quality of fastener forming equipment.

[0017] In one alternative embodiment, the system further includes a first gear and a second gear. The first gear is sleeved on the rotating shaft, and the first gears on the paired rotating shafts mesh with each other. The second gear is disposed on the mounting base and meshes with the first gears on two adjacent sets of rotating shafts.

[0018] Beneficial effects: The first gear meshes with each other, thereby ensuring that the two paired shafts can rotate in opposite directions at the same speed, avoiding speed differences between the paired feed wheels. The second gear meshes with the first gear, thereby ensuring that the shaft connected to the second gear can rotate in the same direction at the same speed, avoiding speed differences between the feed wheels, so that the feeding assembly can transport wire more stably and reliably.

[0019] In one alternative embodiment, the mounting base includes a first base and a second base, the second base being mounted on the first base, the position of the second base being adjustable in the first direction, and one of the paired rotating shafts being disposed on the first base and the other of the paired rotating shafts being disposed on the second base.

[0020] Beneficial effect: By adjusting the position of the second seat in the first direction, the spacing between the paired feeding wheels can be adjusted, so that the paired feeding wheels can better clamp the conveyor wire.

[0021] In one alternative embodiment, the first seat has a positioning groove facing the first direction and passing through the first seat in the axial direction of the rotating shaft, and the second seat is embedded in the positioning groove.

[0022] Beneficial effects: Using the positioning slot for installation can position the second seat in the second direction, ensuring that the paired feeding wheels have an accurate relative position in the first direction, thus improving the feeding effect of the feeding wheels.

[0023] Secondly, this utility model also provides a fastener forming device, including the feeding component provided by this utility model.

[0024] Beneficial effects: The fastener forming equipment includes the feeding component provided by this utility model, and therefore has the corresponding beneficial effects brought by the feeding component, which will not be elaborated here. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0034] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this utility model, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "end," "length," "inner," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0036] Some fastener forming equipment has multiple production modes, capable of processing wires of different diameters or varying the quantity of wires processed simultaneously. When switching production modes, the feeding method must also be adjusted accordingly. In some related technologies, the wire position must be recalibrated after each adjustment, which is not only cumbersome but also slows down production efficiency.

[0037] The following is combined with Figures 1 to 4 The present invention describes embodiments thereof, wherein the first direction is indicated by Z, the second direction by X, and the third direction by Y.

[0038] Reference Figure 1 , Figure 2According to an embodiment of the present invention, a feeding assembly 1 is provided, including a mounting base 101, a plurality of rotating shafts 102 and a plurality of feeding wheels 103. The plurality of rotating shafts 102 are arranged in pairs on the mounting base 101 in a first direction. The rotating shafts 102 are rotatable along their own axes. The rotating shafts 102 include a first positioning step 1021. The plurality of feeding wheels 103 are detachably sleeved on the rotating shafts 102. The feeding wheels 103 include a first feeding groove 1031 and a second feeding groove 1032 that are spaced apart in the circumferential direction.

[0039] The feeding wheel 103 includes a first positioning surface and a second positioning surface. The first positioning surface is located at one end of the feeding wheel 103 in the axial direction, and the second positioning surface is located at the other end of the feeding wheel 103 in the axial direction. The feeding wheel 103 can abut against the first positioning step 1021 through the first positioning surface or the second positioning surface to switch the feeding mode of the feeding wheel 103.

[0040] The feeding assembly 1 is used to feed wire. The axis of the rotating shaft 102 is along the third direction. The wire is clamped between two pairs of feeding wheels 103. Under the rotation of the feeding wheels 103, it is conveyed downstream along the second direction. The feeding wheels 103 can feed in two ways.

[0041] Specifically, the feeding wheel 103 can be positioned and installed via the first positioning surface or the second positioning surface, thereby switching between two different feeding methods. When it is necessary to change the feeding method, it is only necessary to remove the feeding wheel 103, change the installation direction, and make the different positioning surfaces and the first positioning step 1021 abut and position it. There is no need to recalibrate the position. Therefore, the feeding assembly 1 can simplify the operation steps, improve the efficiency of changing the feeding method, and help improve the production efficiency of the fastener forming equipment.

[0042] The first feeding groove 1031 and the second feeding groove 1032 have different specifications, so that the feeding assembly 1 is in two different feeding modes under the two installation methods. The "different specifications" may be that the diameter of the first feeding groove 1031 is larger than the diameter of the second feeding groove 1032; and / or that the number of first feeding grooves 1031 is greater than the number of second feeding grooves 1032. This utility model does not limit this.

[0043] For example, refer to Figure 1 In some embodiments, the diameters of the first feeding groove 1031 and the second feeding groove 1032 are different, and the feeding wheel 103 has two first feeding grooves 1031 and two second feeding grooves 1032.

[0044] Specifically, the fastener forming equipment can produce one part at a time or two parts simultaneously. When the fastener forming equipment produces one part at a time, the feeding wheel 103 uses a first feeding trough 1031 or a second feeding trough 1032 located in the middle to convey a wire downstream. By switching the positioning and installation method of the feeding wheel 103, the positions of the first feeding trough 1031 and the second feeding trough 1032 can be changed, thereby changing the diameter of the wire conveyed downstream. When the fastener forming equipment produces two parts simultaneously, the feeding wheel 103 uses a first feeding trough 1031 and a second feeding trough 1032 near the outer side to convey two wires downstream simultaneously. By switching the positioning and installation method of the feeding wheel 103, the positions of the first feeding trough 1031 and the second feeding trough 1032 can be changed, thereby changing the diameter of the wire conveyed downstream.

[0045] For example, in some embodiments not shown, the number of first feed troughs 1031 and second feed troughs 1032 is different, and the feed wheel 103 has one first feed trough 1031 and two second feed troughs 1032.

[0046] Specifically, the fastener forming equipment can produce one part at a time or two parts simultaneously. When the fastener forming equipment produces one part at a time, the feeding wheel 103 uses the first feeding groove 1031 for feeding. When the fastener forming equipment produces two parts simultaneously, by switching the positioning and installation method of the feeding wheel 103, the feeding wheel 103 is changed to use the second feeding groove 1032 for feeding. At this time, the diameters of the two second feeding grooves 1032 can be the same or different.

[0047] To facilitate disassembly and assembly, in some embodiments, the feed roller 103 and the rotating shaft 102 are fitted with a clearance fit. This clearance fit installation method allows the feed roller 103 to be disassembled and assembled with less effort, further improving the efficiency of changing the feeding method and contributing to increased production efficiency of the fastener forming equipment.

[0048] Optionally, in some embodiments, the feeding assembly 1 further includes a threaded fastener (not shown in the figure), which is disposed at the end of the rotating shaft 102. The threaded fastener presses the feeding wheel 103 against the first positioning step 1021. The threaded fastener reliably presses the feeding wheel 103, thereby ensuring that the positioning effect of the feeding wheel 103 meets the requirements. At the same time, the threaded fastener is easy to install and remove, which can further improve the efficiency of changing the feeding method and help improve the production efficiency of the fastener forming equipment.

[0049] For example, refer to Figure 1 The end of the rotating shaft 102 is machined with a threaded hole, through which threaded fasteners are installed.

[0050] In some embodiments, refer to Figure 2 The rotating shaft 102 includes a first keyway 1022, the feeding wheel 103 includes a second keyway 1033, and the feeding assembly 1 also includes a connecting key (not shown in the figure), which is disposed in the first keyway 1022 and the second keyway 1033. The feeding wheel 103 and the rotating shaft 102 are connected by a key, so that torque can be smoothly transmitted even with a clearance fit, avoiding slippage between the feeding wheel 103 and the rotating shaft 102, and ensuring that the feeding wheel 103 stably feeds out the wire.

[0051] In some embodiments, two pairs of rotating shafts 102 constitute a group of rotating shafts 102, and multiple groups of rotating shafts 102 are spaced apart in a second direction, which is perpendicular to the first direction. By setting multiple groups of rotating shafts 102, the feeding assembly 1 can use multiple groups of feeding rollers 103 to feed simultaneously. The multiple groups of feeding rollers 103 can calibrate the posture of the wire, so that the wire is conveyed straight along the second direction, thereby further improving the feeding quality of the feeding assembly 1 and helping to improve the product quality of the fastener forming equipment.

[0052] To ensure synchronization of the gear sets, in some embodiments, the shafts 102 are meshed with each other via gears. For example, see [reference 1]. Figure 3 The feeding assembly 1 also includes a first gear 1041 and a second gear 1042. The first gear 1041 is sleeved on the rotating shaft 102, and the first gears 1041 of the paired rotating shafts 102 mesh with each other. The second gear 1042 is disposed on the mounting base 101, and the second gear 1042 meshes with the first gears 1041 on the two adjacent sets of rotating shafts 102 respectively.

[0053] The first gear 1041 meshes with each other, thereby ensuring that the two paired rotating shafts 102 can rotate in opposite directions at the same speed, avoiding speed differences between the paired feeding wheels 103. The second gear 1042 meshes with the first gear 1041, thereby ensuring that the rotating shaft 102 connected to the second gear 1042 can rotate in the same direction at the same speed, avoiding speed differences between the feeding wheels 103, so that the feeding assembly 1 can convey wire more stably and reliably.

[0054] In some embodiments, the mounting base 101 includes a first base 1011 and a second base 1012. The second base 1012 is mounted on the first base 1011, and its position in a first direction is adjustable. One of the paired rotating shafts 102 is disposed on the first base 1011, and the other of the paired rotating shafts 102 is disposed on the second base 1012. By adjusting the position of the second base 1012 in the first direction, the spacing between the paired feeding rollers 103 can be adjusted, allowing the paired feeding rollers 103 to better clamp the conveying wire.

[0055] For example, the mounting surface of the second seat 1012 on the first seat 1011 faces the first direction. During installation, by adding a spacer between the second seat 1012 and the first seat 1011, the position in the first direction can be finely adjusted.

[0056] To further position the second seat 1012, in some embodiments, refer to... Figure 2 The first seat 1011 has a positioning groove facing the first direction and passes through the first seat 1011 in the axial direction of the rotating shaft 102. The second seat 1012 is embedded in the positioning groove.

[0057] On the one hand, the positioning groove faces the first direction, and the second seat 1012 is placed at the bottom of the positioning groove. Thus, the position of the second seat 1012 in the first direction can be adjusted by adding a gap plate. On the other hand, the side of the positioning groove in the second direction contacts the second seat 1012, thereby positioning the positioning groove in the second direction and ensuring that the paired feeding wheels 103 have an accurate relative position in the first direction, thereby improving the feeding effect of the feeding wheels 103.

[0058] In some embodiments, the feeding assembly further includes a fixing member disposed on the first seat 1011, which presses down on and positions the second seat 1012 in a first direction.

[0059] In some embodiments, the feeding assembly further includes an elastic element disposed between the fixing member and the second seat 1012 for pressing the second seat 1012. The fixing member indirectly presses the second seat 1012 through the elastic element, so that the second seat 1012 has a certain degree of floating freedom in the first direction, and the force of the feeding wheel 103 clamping the conveying wire can be adjusted by changing the elastic force of the elastic element.

[0060] For example, the fastener can be a threaded fastener and the elastic element is a compression spring. The compression spring is sleeved on the threaded fastener, so that one end abuts against the threaded fastener and the other end abuts against the second seat 1012, pressing the second seat 1012 against the first seat 1011.

[0061] Understandably, besides Figure 2 In addition to the method shown in the embodiment, the second base 1012 can also be installed and positioned on the first base 1011 in other ways. Other positioning methods can be referred to the relevant prior art, which will not be described in detail here.

[0062] In some embodiments, the mounting base 101 includes a second positioning step, through which the rotating shaft 102 is positioned and installed, thereby achieving axial positioning.

[0063] Secondly, this utility model also provides a fastener forming device, including the feeding component 1 provided by this utility model.

[0064] Beneficial effects: The fastener forming equipment includes the feeding component 1 provided by this utility model, and therefore has the beneficial effects brought by the feeding component 1, which will not be elaborated here.

[0065] Figure 4 The main structure of an embodiment of a fastener forming device is illustrated by way of example, with reference to Figure 4 In some embodiments, the fastener forming equipment further includes a frame 2, and a feeding assembly 1 is disposed on the frame 2.

[0066] Furthermore, in some embodiments, the frame 2 is also provided with a die (not shown in the figure), a punching assembly 3, an ejector assembly 4, a transfer assembly 5, and a shearing assembly (not shown in the figure). The shearing assembly cuts the wire fed by the feeding assembly 1 to obtain a bar for cold heading. The transfer assembly 5 clamps the bar and transfers it between the punching assembly 3 and the die. The punching assembly 3 punches the wire, causing the wire to deform according to the shape of the die. The ejector assembly 4 pushes the punched wire out of the die from the other side of the die, completing the cold heading process.

[0067] For example, in Figure 4 In the fastener forming equipment shown, the frame 2 has two mold mounting areas. In one scenario, the feeding assembly 1 feeds a wire (using one of the first feeding grooves 1031 or one of the second feeding grooves 1032 located in the middle of the feeding wheel 103). The two mold mounting areas are equipped with different molds. The fastener forming equipment processes parts through a two-mold process (e.g., two-mold two-punch, two-mold four-punch, etc.). By changing the mounting direction of the feeding wheel 103, the currently used feeding groove can be changed, thereby changing the specifications of the input wire.

[0068] In another scenario, the feeding assembly 1 is switched to feeding two wires (using both the outer first feeding groove 1031 and the second feeding groove 1032). The two mold installation areas are equipped with the same or different molds. The fastener forming equipment processes two parts simultaneously through a single-mold process (e.g., one mold for one punch, one mold for two punches, etc.). By changing the installation direction of the feeding wheel 103, the feeding groove corresponding to the mold can be changed, thereby changing the specifications of the input wire.

[0069] Of course, in other embodiments not shown, the frame 2 may also have more mold mounting areas to meet the needs of processing technologies such as three-mold process and four-mold process, which will not be elaborated here.
