Description

Technical Field

[0001] This utility model relates to the field of fastener forming technology, specifically to multi-line fastener forming equipment. Background Technology

[0002] Fastener forming equipment can process wire into parts such as screws and rivets. The fastener forming equipment first cuts the wire into bars, then transfers the bars to the mold, and forms the parts by stamping.

[0003] In related technologies, fastener forming equipment can only produce one specification of part at a time. Each time the production specification is changed, the machine needs to be stopped to change the mold, which increases the cost of small batch orders and is not conducive to meeting flexible and ever-changing production needs. Utility Model Content

[0004] In view of this, the present invention provides a multi-line fastener forming equipment to solve the problem of limited production specifications in fastener forming equipment.

[0005] In a first aspect, this utility model provides a multi-wire fastener forming device, including a frame, a shearing assembly, and a transfer assembly. The frame includes multiple feeding positions and multiple stamping positions, which are arranged sequentially at intervals in a first direction. Each feeding position has a feeding hole for feeding wire, and each stamping position has a main die. The shearing assembly is disposed on the frame and located on one side of the feeding hole in a second direction. The shearing assembly includes scissors that are movable in the second direction to cut the wire. The transfer assembly is disposed on the frame and located on the other side of the feeding hole in the second direction. The transfer assembly includes multiple grippers that are movable in the first direction to deliver the cut wire to each of the main dies.

[0006] Beneficial effects: The scissors move in the second direction, allowing multiple wires to be cut simultaneously without interference. This enables the grippers to deliver each wire to its corresponding main mold, allowing the multi-wire fastener forming equipment to produce multiple parts at the same time. When the specifications of each main mold are the same, the multi-wire fastener forming equipment can improve the production efficiency of parts and achieve rapid production. When the specifications of each main mold are different, the multi-wire fastener forming equipment can produce parts of multiple specifications at the same time, increasing production efficiency several times over. It can effectively solve the high cost problem of small-batch order production and can also meet the production needs of multiple specifications of parts while reducing the number of equipment.

[0007] In one optional embodiment, the frame further includes a main mold base, the main mold base having a first mounting hole, and the main mold being detachably disposed in the first mounting hole.

[0008] Beneficial effects: The use of a detachable main mold further enriches the specifications of parts that can be produced by the multi-line fastener forming equipment. The main mold is positioned and installed through the first mounting hole, which can be installed accurately and conveniently, thus improving installation efficiency.

[0009] In one optional embodiment, the main mold base is further provided with a second mounting hole, and the frame further includes a feeding nozzle, which is detachably disposed in the second mounting hole, and the feeding hole is located at the feeding nozzle.

[0010] Beneficial effects: For master molds of different specifications, the wire diameter required for producing parts may vary. By setting a detachable feed nozzle, the specifications of the feed hole can be flexibly adjusted according to the corresponding master mold to meet the production needs of parts of different specifications.

[0011] In one optional embodiment, the frame further includes an upper base and a mold base pad, the upper base having a mold base cavity, the main mold base being disposed within the mold base cavity, and the mold base pad being placed between the mold base cavity and the main mold base in a third-order orientation.

[0012] Beneficial effects: By adjusting the thickness of the mold base plate, the installation position of the main mold base on the upper machine base can be fine-tuned, thereby fine-tuning the production effect of the parts and improving the production quality of the parts.

[0013] In one alternative embodiment, the frame further includes a first feed hole, which is located on the same side of the feed hole as the transfer assembly in the second direction. The multi-wire fastener forming equipment further includes a feed assembly, which includes a first feed rod disposed within the first feed hole. The first feed rod is movable in the third direction to push the wire out of the scissors.

[0014] Beneficial effects: The scissors move in the second direction to cut the wire and continue to move to the position corresponding to the first feed hole. The first feed rod pushes out the wire, releasing the scissors from the wire so that the transfer assembly can transfer the cut wire without obstruction.

[0015] In one alternative embodiment, the frame further includes a second feed hole located at the stamping position, and the feed assembly includes a second feed rod disposed within the second feed hole. The second feed rod is capable of moving upward in the third direction to eject the wire from the main die.

[0016] Beneficial effect: After stamping is completed, the second feed rod pushes the wire out of the main die so that the main die can receive new wire for the next round of stamping.

[0017] In one alternative embodiment, the cutting assembly includes a shear seat, the shears being detachably mounted on the shear seat, the shears including a shear hole whose size corresponds to the size of the wire.

[0018] Beneficial effects: During cutting, the shear hole and the feed hole are aligned first. The wire fed from the feed hole passes through the shear hole. Then the shear moves in the second direction to cut the wire. During cutting, the inner wall of the shear hole can provide uniform support to the outer circumference of the wire, making the cut smoother and more uniform, which meets the needs of producing high-quality parts.

[0019] In an optional embodiment, a feeding assembly is further included, the feeding assembly comprising a plurality of feeding wheels whose axes are along the first direction and arranged in pairs in the second direction, the outer periphery of the feeding wheels having a plurality of clamping grooves for passing through the wire, the feeding wheels being rotatable to feed the wire.

[0020] Beneficial effects: The wire clamping groove is used to feed wire into the feeding hole. Multiple wire clamping grooves are spaced apart in the first direction to meet the needs of feeding wire into multiple feeding holes.

[0021] In one alternative embodiment, a stamping assembly is further included, the stamping assembly comprising a plurality of dies arranged opposite to the main die in a third-party direction, the dies being movable in the third-party direction to stamp the wire.

[0022] Beneficial effect: The punch and the main die are close to each other, thereby stamping the wire into shape.

[0023] In one optional embodiment, the stamping assembly further includes a first slide, a second slide, and a die holder. The first slide is disposed on the frame and is movable in the third direction. The second slide is disposed on the first slide and is movable in the second direction. The die holder is disposed on the second slide, and a plurality of dies are disposed on the die holder along the second direction.

[0024] Beneficial effects: The first slide table presses the die against the main die, and the second slide table allows the die to switch positions in the second direction, thereby pressing against the main die in different states, realizing multiple stamping on a single main die, and meeting the needs of multi-stamping process in stamping.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] In related technologies, fastener forming equipment can produce parts of different specifications by changing molds. For small-batch orders, fastener forming equipment needs to be stopped frequently to change molds, which increases the proportion of downtime, thereby increasing the cost of small-batch orders. This is not conducive to meeting flexible and ever-changing production needs and also reduces the market competitiveness of the products.

[0039] The following is combined with Figures 1 to 6The following describes an embodiment of the present invention. In the figure, the first direction is the X direction, the second direction is the Z direction, and the third direction is the Y direction.

[0040] Reference Figure 1 , Figure 2 According to an embodiment of the present invention, a multi-wire fastener forming device is provided, including a frame 1, a shearing assembly 2, and a transfer assembly 3. The frame 1 includes a plurality of feeding positions 101 and a plurality of stamping positions 102, which are arranged sequentially at intervals in a first direction. The feeding positions 101 have feeding holes for feeding wires, and the stamping positions 102 have main molds (not shown in the figure). The shearing assembly 2 is disposed on the frame 1 and is located on one side of the feeding holes in a second direction. The shearing assembly 2 includes scissors 201, which can move in the second direction to cut the wires. The transfer assembly 3 is disposed on the frame 1 and is located on the other side of the feeding holes in the second direction. The transfer assembly 3 includes a plurality of grippers 301, which can move in the first direction to send the cut wires to the respective main molds.

[0041] The scissors 201 move in the second direction, thereby cutting multiple wires simultaneously without interference. The grippers 301 then deliver each wire to its corresponding main mold, enabling the multi-wire fastener forming equipment to produce multiple parts at the same time. When the specifications of each main mold are the same, the multi-wire fastener forming equipment can increase the production efficiency of parts several times, achieving rapid production. When the specifications of each main mold are different, the multi-wire fastener forming equipment can produce parts of multiple specifications at the same time. In addition to improving production efficiency, it can also effectively solve the high cost problem of small-batch order production, and can also meet the production needs of multiple specifications of parts while reducing the number of equipment.

[0042] Understandably, in related technologies, the scissors 201 generally move along the first direction to cut the wire. However, corresponding to multiple stamping positions 102 arranged at intervals in the first direction, the feeding positions 101 also need to be arranged at intervals in the first direction so that the grippers 301 can send each wire to the corresponding main mold. This results in the scissors 201 moving along the first direction being unable to cut multiple wires at the same time. This utility model meets the needs of multi-wire fastener forming equipment for simultaneously inputting, cutting, and stamping multiple wires by changing the movement mode of the scissors 201.

[0043] It should be noted that when multiple feeding holes and multiple different main dies are used at the same time, the multi-wire fastener forming equipment has the ability to produce parts of multiple specifications at the same time. However, it is not excluded that the multi-wire fastener forming equipment may only selectively use a portion of the feeding holes and main dies. For example, when there is only a small batch order of one specification, the wire can be fed out from only one feeding hole. This utility model does not limit this.

[0044] In some embodiments, refer to Figure 3 The frame 1 also includes a main mold base 103, which has a first mounting hole 1031. The main mold is detachably mounted in the first mounting hole 1031. When the current main mold does not match the part specifications required by the order, the production specifications of the multi-line fastener forming equipment can be changed by stopping the machine and replacing it with a new main mold, thereby further enriching the specifications of the parts that the multi-line fastener forming equipment can produce. The main mold is positioned and installed through the first mounting hole 1031, which can be accurately and conveniently installed in place, improving installation efficiency.

[0045] Furthermore, in some embodiments, the main mold base 103 also has a second mounting hole 1032, and the frame 1 also includes a feed nozzle (not shown in the figure), which is detachably disposed in the second mounting hole 1032, and the feed hole is located in the feed nozzle. For different specifications of main molds, the wire diameter required for producing parts may vary. By setting a detachable feed nozzle, the specifications of the feed hole can be flexibly adjusted according to the corresponding main mold to meet the production needs of parts of different specifications.

[0046] For example, refer to Figure 3 Next to the first mounting hole 1031, there is a countersunk hole 1033. The side of the countersunk hole 1033 is connected to the first mounting hole 1031. The main mold is fixed in the countersunk hole 1033 by screws and fasteners. The screws and fasteners are recessed into the countersunk hole 1033 to avoid being exposed and affecting the stamping. The feed nozzle is embedded in the second mounting hole 1032 and is fixed by the cooperation of the inner wall of the second mounting hole 1032.

[0047] In some embodiments, the frame 1 further includes an upper base 104 and a mold base pad. The upper base 104 has a mold base cavity, and the main mold base 103 is disposed within the mold base cavity. The mold base pad is placed between the mold base cavity and the main mold base in the third direction. The mold base cavity faces the third direction. By adjusting the thickness of the mold base pad, the mounting position of the main mold base 103 on the upper base 104 along the third direction can be fine-tuned, thereby fine-tuning the production effect of the parts and improving the production quality of the parts.

[0048] In some embodiments, the frame 1 further includes a first feed hole 1034, which is located on the same side of the feed hole as the transfer assembly 3 in a second direction. The multi-wire fastener forming equipment also includes a feed assembly 4, which includes a first feed rod 401 disposed in the first feed hole 1034. The first feed rod 401 is capable of moving upward in a third direction to push the wire out of the scissors 201.

[0049] For example, in Figure 3In the illustrated embodiment, since the feeding hole is located in the main mold base 103, the first material passage hole 1034 can also be provided in the main mold base 103. In other embodiments not shown, the feeding hole and the first material passage hole can also be provided in other parts of the frame 1. This utility model does not limit this.

[0050] Reference Figure 3 and Figure 4 The scissors 201 move in the second direction to cut the wire and continue moving to the position corresponding to the first feed hole 1034. The first feed rod 401 pushes out the wire, releasing the constraint of the scissors 201 on the wire, so that the transfer assembly 3 can transfer the cut wire without obstruction. In other words, during the production process, the cut wire first moves along the second direction and then moves along the first direction.

[0051] In some embodiments, the frame 1 further includes a second feed hole located at the stamping position 102. The feed assembly 4 includes a second feed rod 402 disposed within the second feed hole. The second feed rod 402 is capable of moving upward in the third direction to push the wire out of the main die.

[0052] After stamping is completed, the second feed rod 402 pushes out the wire in the main die so that the main die can receive new wire for the next round of stamping.

[0053] Continue to refer to Figure 4 In some embodiments, the shearing assembly 2 includes a shear seat 202, and shears 201 are detachably mounted on the shear seat 202. Shears 201 includes a shear hole 2011, the size of which corresponds to the size of the wire. During cutting, the shear hole 2011 is first aligned with the feed hole, and the wire fed from the feed hole passes through the shear hole 2011. Then, the shears 201 moves in a second direction to cut the wire. During cutting, the inner wall of the shear hole 2011 provides uniform support to the outer periphery of the wire, resulting in a smoother and more uniform cut, meeting the requirements for producing high-quality parts.

[0054] Reference Figure 5 In some embodiments, the multi-wire fastener forming equipment further includes a feeding assembly 5, which includes a plurality of feeding wheels 501. The axes of the feeding wheels 501 are along a first direction and arranged in pairs in a second direction. The outer periphery of the feeding wheels 501 is provided with a plurality of wire clamping grooves for passing through the wire. The feeding wheels 501 are rotatable to feed the wire. Specifically, the feeding assembly 5 also includes a mounting base 502, which is disposed on the frame 1, and the feeding wheels 501 are disposed on the mounting base 502.

[0055] The wire clamping groove is used to feed wire into the feeding hole. Multiple wire clamping grooves are spaced apart in the first direction to meet the need to feed wire into multiple feeding holes.

[0056] In some embodiments, the multi-wire fastener forming apparatus further includes a stamping assembly 6, which includes a plurality of dies (not shown) arranged opposite to a main die in a third-party direction. The dies are movable in the third-party direction to stamp the wire. The dies and the main die approach each other, thereby stamping the wire into shape.

[0057] In some embodiments, the stamping assembly 6 further includes a first slide 601, a second slide 602, and a die holder 603. The first slide 601 is disposed on the frame 1 and is movable in a third direction. The second slide 602 is disposed on the first slide 601 and is movable in a second direction. The die holder 603 is disposed on the second slide 602, and a plurality of dies are disposed on the die holder 603 along the second direction.

[0058] Understandably, stamping (hot or cold) in related technologies has various stamping processes such as one die two-stamping (using one main die and performing two stampings), two dies two-stamping, and two dies four-stamping. The first slide 601 presses the die against the main die, and the second slide 602 allows the die to switch positions in the second direction, thereby pressing against the main die in different states, realizing multiple stampings on one main die, so that the multi-line fastener forming equipment can meet the needs of one die multi-stamping process.

[0059] In addition, for a single-die multi-punch process, the gripper 301 only needs to transfer the wire from the scissors 201 to the main die. After the part is processed, it can leave the main die under the action of the feed assembly 4. For a multi-die multi-punch process, the transfer assembly 3 also needs to meet the requirement of transferring the wire between the main dies.

[0060] Exemplarily, in some embodiments, the gripper 301 may be further divided into a first gripper and a second gripper. The first gripper is used to transfer the wire from the scissors 201 to the first main mold, and the second gripper is used to transfer the wire between the upstream and downstream main molds. Of course, in addition to this example, the gripper 301 may also use other methods to transfer the wire between the main molds, and the present invention does not limit this.

[0061] In some embodiments, the multi-wire fastener forming equipment further includes a driver and a main shaft 7. The driver drives the main shaft 7 to rotate. The shears 201, grippers 301, first feed rod 401, second feed rod 402, feeding wheel 501, first slide 601, and second slide 602 are respectively connected to the main shaft 7 for transmission, so that the shears 201, grippers 301, first feed rod 401, second feed rod 402, feeding wheel 501, first slide 601, and second slide 602 can operate synchronously according to a set rhythm.

[0062] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
