Description

Technical Field

[0001] This utility model relates to the field of automated riveting technology, specifically to a rivet transfer assembly, a riveting mechanism, and a triangular hanging rivet riveting machine. Background Technology

[0002] Many industries require the installation of hardware such as hooks on products, and riveting is often used to attach these hardware components to the products.

[0003] When performing automated design, two sets of feeding mechanisms are usually set up to feed hardware parts and rivets respectively. The hardware parts and rivets are riveted onto the product at the riveting station by the cooperation of the upper punch and the lower die.

[0004] Rivet feeding typically uses a vibratory feeder to arrange rivets in an orderly manner and transport them to the riveting station. A major challenge in automated design is achieving the sequential feeding of rivets from the vibratory feeder to the stamping station. Therefore, the purpose of this application is to provide a device for sequentially feeding rivets from a vibratory feeder to the stamping station. Utility Model Content

[0005] Based on the above description, this utility model provides a rivet transfer assembly, a riveting mechanism, and a triangular hanging rivet riveting machine to achieve the purpose of feeding rivets output by the vibratory feeder one by one to the stamping station.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] Firstly, this application provides a rivet transfer assembly, the technical solution of which is as follows:

[0008] A rivet transfer assembly, comprising:

[0009] A transfer base is provided with a temporary storage cavity, a feeding channel arranged along a first direction, and a discharging channel arranged along a second direction. The first direction and the second direction are perpendicular. The feeding channel and the discharging channel are both connected to the temporary storage cavity and the outside. The temporary storage cavity is used to temporarily store a single rivet. When there is a rivet in the temporary storage cavity, the rivet in the feeding channel is blocked from entering the temporary storage cavity by the rivet in the temporary storage cavity.

[0010] A feeding component connected to the transfer seat is used to push a single rivet in the temporary storage cavity out of the discharge channel.

[0011] Preferably, the transfer seat is provided with a guide groove along the second direction, the guide groove and the discharge barrel are located on opposite sides of the temporary storage cavity, the guide groove connects the temporary storage cavity to the outside, the feeding member is provided in the guide groove and can move along the second direction, and is suitable for pushing a single rivet in the temporary storage cavity out of the discharge channel by moving the feeding member along the second direction.

[0012] Preferably, a blocking member is connected to the transfer base. The blocking member can rotate relative to the transfer base about an axis perpendicular to both the first and second directions. The blocking member can rotate to a first position or a second position. In the first position, the blocking member is partially located in the discharge channel and in contact with the rivet located in the temporary storage cavity. In the second position, the blocking member is located outside the movement path and path extension line of the rivet when it is output from the discharge channel. When the blocking member rotates from the first position to the second position, it overcomes the elastic force of the first elastic member between the blocking member and the transfer base. It is suitable for driving the blocking member to rotate from the first position to the second position when the feeding member pushes a single rivet in the temporary storage cavity out of the discharge channel.

[0013] Preferably, in a direction perpendicular to both the first and second directions, the temporary storage cavity, the feeding channel, and the discharging channel are each divided into a head region and a rod region. The head regions of the feeding channel and the discharging channel are connected to the head region of the temporary storage cavity, and the rod regions of the feeding channel and the discharging channel are connected to the rod region of the temporary storage cavity.

[0014] Secondly, this application provides a riveting mechanism, comprising:

[0015] The rivet transfer assembly described above is used for mounting on a machine base, wherein both the first and second directions are horizontal, and the rivet is vertical with its head facing upward when it is located in the temporary storage cavity;

[0016] A riveting assembly for mounting on a machine base, comprising:

[0017] The punch and lower die are distributed vertically. The punch can move vertically, and the rivet is located directly above the lower die after being output from the discharge channel.

[0018] A receiving member is disposed between the punch and the lower die. The receiving member can move vertically relative to the machine platform and relative to the punch. The receiving member can descend from a third position to a fourth position relative to the machine platform. When the receiving member is in the third position, it connects with the transfer seat and receives the rivet output from the discharge channel. When the receiving member is in the fourth position, it is restricted from continuing to move downward relative to the machine platform. When the receiving member moves from the third position to the fourth position, it overcomes the elastic force of the second elastic member located between the receiving member and the machine platform.

[0019] Specifically, when the receiving part is in the third position and is receiving a rivet, the punch abuts against the rivet during its descent and drives the receiving part to descend through the rivet. When the receiving part descends to the fourth position, the punch continues to descend, causing the rivet to disengage from the receiving part.

[0020] Preferably, the receiving component includes a first state and a second state. In the first state, the receiving component can receive rivets output from the discharge channel and support the rivet head in the vertical direction. In the second state, the vertical projections of the punch and the rivet head on the receiving component do not intersect with the receiving component. When the receiving component descends from the third position to the fourth position, it maintains the first state. When the receiving component descends to the fourth position, the punch continues to descend, driving the receiving component to switch to the second state through the rivet head.

[0021] Preferably, the receiving component is connected to the machine tool through an elastic connector, and the receiving component overcomes the elastic force of the elastic connector when switching from the first state to the second state.

[0022] Preferably, the receiving member has a receiving groove on one side in the horizontal direction, the receiving groove is through at both ends in the vertical direction, the receiving groove is divided into a head section and a rod section distributed vertically, and the receiving member is connected to the outlet of the discharge channel when it is in the third position.

[0023] The receiving component includes two splicing components distributed in a horizontal direction, and each of the two splicing components is provided with a portion of the receiving groove. The two splicing components are respectively connected to the machine base through the elastic connector. When the two connectors move away from each other in the horizontal direction, they overcome the elastic force of the elastic connector. In the first state, the two splicing components are spliced ​​together to form a complete receiving groove. When the receiving component switches to the second state, the two connectors overcome the elastic force of the elastic connector and move away from each other. It is suitable that when the receiving component descends to the fourth position, the punch continues to descend and drives the two connectors to overcome the elastic force of the elastic connector and move away from each other through the rivet head.

[0024] Preferably, the bottom surface of the receiving groove head section is provided with a guide groove that communicates with the rod section, and the diameter of the guide groove gradually decreases from top to bottom.

[0025] Thirdly, this application provides a triangular hook rivet pressing machine, including the riveting mechanism described above.

[0026] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects:

[0027] 1. The rivet transfer assembly of this application is equipped with a transfer base, which includes a temporary storage cavity, a feeding channel, and a discharge channel. During actual installation, the feeding channel connects to the discharge port of the vibratory feeder, allowing rivets output one by one from the vibratory feeder to enter the feeding channel. Under the weight of subsequent rivets, they are pushed into the temporary storage cavity, where only a single rivet can exist at a time. Rivets from subsequent feeding channels are prevented from entering the temporary storage cavity. Then, a feeding component pushes the single rivet from the temporary storage cavity out of the discharge channel, thus achieving the output of a single rivet. After the feeding component resets, the rivets in the feeding channel are pushed back into the temporary storage cavity by the weight of subsequent rivets. Repeating this process achieves the sequential output of rivets, thereby enabling the vibratory feeder to deliver rivets one by one to the stamping station.

[0028] 2. The rivet transfer assembly of this application is equipped with a blocking member. When the feeding member is not in operation, the blocking member is partially kept in the discharge channel under the elastic force of the first elastic member, so as to prevent the rivets in the temporary storage cavity from being output from the discharge channel. This avoids the rivets in the temporary storage cavity being pushed into the discharge channel and output under the gravity of the rivets output by the vibratory plate during the stamping process, thus ensuring that the stamping work is carried out in an orderly and safe manner.

[0029] 3. The riveting mechanism of this application, by setting up a receiving component, is positioned in the third position under the elastic force of the second elastic element when the punch resets. This allows it to receive a single rivet output from the transfer seat. At this time, the rivet is directly above the lower die and directly below the punch. During the stamping action, the punch descends and abuts against the rivet. The rivet drives the receiving component to descend against the elastic force of the second elastic element. When the receiving component descends to the fourth position, it is prevented from continuing to descend. At this point, the punch continues to descend, causing the rivet to disengage from the receiving component and cooperate with the lower die to complete the riveting. After riveting is completed, the punch rises and resets, and the receiving component returns to the third position under the elastic force of the second elastic element. The rivet transfer assembly then outputs another rivet onto the receiving component. Repeating the above process achieves automatic riveting.

[0030] 4. The riveting mechanism of this application sets the receiving component to include a first state and a second state. When switching from the first state to the second state, it overcomes the elastic force. In the first state, the receiving component supports the rivet head, so that it can be driven down by the rivet and the punch before descending to the fourth position. During this process, the receiving component plays the role of supporting and positioning the rivet. When the receiving component reaches the fourth position, the pressure of the punch and the rivet overcomes the elastic force, causing the receiving component to switch to the second state. Until the second state is reached, the projections of the punch and the rivet head in the vertical direction do not intersect with the receiving component. At this time, the rivet can descend with the punch to detach from the receiving component, and with the cooperation of the lower die, the rivet is deformed to complete the riveting.

[0046] Reference Figure 1As shown in the figure, this application provides a triangular hook rivet riveting machine, including a machine base 1, a stamping station on the machine base 1, a riveting assembly 2 in the stamping station, a rivet feeding vibratory feeder 3 on the machine base 1 for supplying rivets to the riveting assembly 2, and a rivet transfer assembly 4 located between the rivet feeding vibratory feeder 3 and the riveting assembly 2 on the machine base 1. The rivet transfer assembly 4 transfers the rivets output by the rivet feeding vibratory feeder 3 to the riveting assembly 2 one by one, so as to realize the purpose of feeding the rivets output by the rivet feeding vibratory feeder 3 to the stamping station one by one.

[0047] Reference Figure 1 As shown, the riveting assembly 2 and the rivet transfer assembly 4 constitute the riveting mechanism. A mounting frame 11 is provided on the machine base 1, and the riveting assembly 2, the rivet feeding vibratory plate 3 and the rivet transfer assembly 4 are all mounted on the mounting frame 11.

[0048] Reference Figure 2-3 As shown, the rivet transfer assembly 4 includes a transfer base 41 and a feeding component. The transfer base 41 is provided with a temporary storage cavity 411, a feeding channel 412 arranged along a first direction, and a discharge channel 413 arranged along a second direction. The first and second directions are perpendicular. Both the feeding channel 412 and the discharge channel 413 are connected to the temporary storage cavity 411 and the outside. The temporary storage cavity 411 is used to temporarily store a single rivet. When a rivet is present in the temporary storage cavity 411, the rivet in the feeding channel 412 is blocked from entering the temporary storage cavity 411. The feeding component is connected to the transfer base 41 and is used to push the single rivet in the temporary storage cavity 411 out of the discharge channel 413.

[0049] Reference Figure 2-3 As shown, in this embodiment, the transfer seat 41 is fixed on the mounting frame 11, and both the first and second directions are horizontal. The inlet of the feeding channel 412 is connected to the discharge track of the rivet feeding vibratory plate 3, so that the rivets output by the rivet feeding vibratory plate 3 directly enter the feeding channel 412 and are pushed into the temporary storage cavity 411 under the gravity of the subsequent rivets. Since only a single rivet can exist in the temporary storage cavity 411, the rivets in the subsequent feeding channel 412 are blocked from entering the temporary storage cavity 411 by the rivets in the temporary storage cavity 411.

[0050] Reference Figure 2-3As shown, in directions perpendicular to both the first and second directions, the temporary storage cavity 411, the feeding channel 412, and the discharging channel 413 are each divided into a head region and a rod region. The head regions of the feeding channel 412 and the discharging channel 413 are connected to the head region of the temporary storage cavity 411, and the rod regions of the feeding channel 412 and the discharging channel 413 are connected to the rod region of the temporary storage cavity 411. In this embodiment, the head region and the rod region are distributed vertically, respectively accommodating the head and rod of the rivet. The discharge track of the rivet feeding vibratory feeder 3 outputs the rivet in a head-up, rod-down posture and sends it into the feeding channel 412, maintaining this stable state during transport. This ensures that the rivet is stably transported to the stamping station in a head-up, rod-down posture, eliminating the need for further adjustment of the rivet's posture.

[0051] Reference Figure 2-3 As shown, to achieve the purpose of the feeding component pushing a single rivet from the temporary storage cavity 411 out of the discharge channel 413, the transfer seat 41 is provided with a guide groove 414 along the second direction. The guide groove 414 and the discharge bucket are located on opposite sides of the temporary storage cavity 411. The guide groove 414 connects the temporary storage cavity 411 to the outside. The feeding component is located in the guide groove 414 and can move along the second direction, which is suitable for pushing a single rivet from the temporary storage cavity 411 out of the discharge channel 413 by the feeding component moving along the second direction.

[0052] Reference Figure 2-3 As shown, specifically, the feeding component is a feeding plate 42, which extends along the second direction and is located in the guide groove 414. Specifically, one end of the feeding plate 42 away from the discharge channel 413 extends out of the guide groove 414, and a feeding cylinder 43 is installed on the transfer seat 41 to control the movement of the feeding plate 42. Correspondingly, the axis of the feeding cylinder 43 is parallel to the second direction, the cylinder body and the transfer seat 41 are fixed, and the piston rod is fixed to the feeding plate 42.

[0053] Reference Figure 3 As shown, the feeding channel 412, the temporary storage cavity 411, the discharge channel 413 and the guide groove 414 are all opened on the top surface of the transfer seat 41, and a cover plate 44 is installed on the top surface of the transfer seat 41 to cover the feeding channel 412, the temporary storage cavity 411, the discharge channel 413 and the guide groove 414.

[0054] Reference Figure 2-3As shown, further, in order to prevent the rivets in the temporary storage cavity 411 from being pushed into the discharge channel 413 by the gravity of the rivets on the discharge track of the feed channel 412 and the rivet feeding vibratory plate 3, a blocking member is connected to the transfer seat 41. The blocking member can rotate relative to the transfer seat 41 about an axis that is perpendicular to both the first and second directions. The blocking member can rotate to the first position or the second position. In the first position, the blocking member is partially located in the discharge channel 413 and in contact with the rivets located in the temporary storage cavity 411. In the second position, the blocking member is located outside the movement path and path extension line of the rivets when they are output from the discharge channel 413. When the blocking member rotates from the first position to the second position, it overcomes the elastic force of the first elastic member between the blocking member and the transfer seat 41. It is suitable for driving the blocking member to rotate from the first position to the second position when the feeding member pushes a single rivet in the temporary storage cavity 411 out of the discharge channel 413.

[0055] Reference Figure 2-4 As shown, specifically, a receiving groove 415 is provided on the transfer base 41, which is connected to the discharge channel 413. In the second direction, the end of the receiving groove 415 away from the guide groove 414 is through. The blocking member includes a blocking block 45, which is accommodated in the receiving groove 415. The blocking block 45 can rotate around the vertical axis. In this embodiment, an installation groove 416 communicating with the receiving groove 415 is also provided on the side wall of the transfer base 41. An installation block 46 is provided in the installation groove 416. The installation block 46 is rotatably connected to the transfer base 41 via a vertical rotating shaft 29. The blocking block 45 is fixed to the installation block 46, so that the position switching is achieved by rotating the installation block 46 to drive the blocking block 45 to rotate.

[0056] In this embodiment, the first elastic element is a torsion spring (not shown in the figure). The torsion spring is coaxially sleeved on the rotating shaft 29 and its two ends are respectively connected to the mounting block 46 and the material transfer seat 41, so that the blocking block 45 is kept in the first position without being subjected to other forces by the elastic force provided by the torsion spring.

[0057] Reference Figure 5 As shown, the riveting assembly 2 includes a punch 21, a lower die 22, and a receiving member 23. The punch 21 and the lower die 22 are arranged vertically. The punch 21 can move vertically, and the rivet is located directly above the lower die 22 after being output from the discharge channel 413. The receiving member 23 is located between the punch 21 and the lower die 22. The receiving member 23 can move vertically relative to the machine base 1 and relative to the punch 21. The receiving member 23 can descend from a third position to a fourth position relative to the machine base 1. When the receiving member 23 is in the third position, it connects with the transfer seat 41 and receives the rivet output from the discharge channel 413. When the receiving member 23 is in the fourth position, it is restricted from continuing to move downward relative to the machine base 1, and when the receiving member 23 moves from the third position to the fourth position, it overcomes the elastic force of the second elastic member 29 located between the receiving member 23 and the machine base 1.

[0058] When the receiving part 23 is in the third position and is receiving a rivet, the punch 21 resists the rivet during its descent and drives the receiving part 23 to descend through the rivet. When the receiving part 23 descends to the fourth position, the punch 21 continues to descend, causing the rivet to disengage from the receiving part 23.

[0059] Reference Figure 5 As shown, specifically, the mounting bracket 11 has a vertically arranged guide rail, on which two vertically distributed slides are connected. A punch 21 seat is mounted on the upper slide, and the punch 21 is connected to the punch 21 seat. The receiving part 23 is connected to the lower slide. The cooperation of the guide rail and the slides guides and limits the vertical movement of the punch 21 and the receiving part 23, improving stability. The mechanism for driving the punch 21 to rise and fall is a conventional technical means and will not be described in detail here.

[0060] Reference Figure 1 and Figure 5 As shown, the lower mold 22 is fixed on the machine base 1, and an operating table 12 is provided on the machine base 1 above the lower mold 22. The operating table 12 has a horizontal surface and is used to support the product to be processed. Through holes for hardware parts and rivets are provided on the operating table 12 at the position of the lower mold 22.

[0061] Reference Figure 5 As shown, a mounting base 25 is installed on the slide below, and a receiving part 23 is connected to the mounting base 25. The mounting base 25 is provided with a through hole for the punch 21 to pass through.

[0062] Reference Figure 5 As shown, to restrict the movement of the receiving component 23, a limiting block 251 is also provided on the mounting base 25. The top and bottom surfaces of the limiting block 251 are both horizontal planes. A limiting seat 26 is provided on the mounting bracket 11. The limiting seat 26 is fixed on the mounting base 25, and the upper and lower ends of the limiting seat 26 extend horizontally to form limiting portions 261. The limiting block 251 is located between the two limiting portions 261. Each of the two limiting portions 261 is threaded with a vertically oriented limiting screw 27. The heads of the limiting screws 27 face the limiting block 251. When the limiting block 251 moves up and down with the mounting base 25, it abuts against the upper limiting screw 27 when it moves to the highest position, at which time the receiving component 23 is in the third position. When it moves to the lowest position, it abuts against the lower limiting screw 27, at which time the receiving component 23 is in the fourth position. In actual design, the height of the receiving part 23 when it is in the third position can be adjusted by adjusting the upper limit screw 27 according to the specific height of the transfer seat 41, so as to ensure that the rivets output in the transfer seat 41 are received by the receiving part 23.

[0063] The second elastic element 29 is a tension spring. A connecting rod is provided on the upper limiting part 261 and the limiting block 251 respectively. The two ends of the tension spring are fixed to the two connecting rods respectively, so as to provide the power for the receiving part 23 to reset to the third position through the tension spring.

[0064] The receiving component 23 includes a first state and a second state. In the first state, the receiving component 23 can receive the rivets output from the discharge channel 413 and support the rivet head in the vertical direction. In the second state, the projections of the rivet head on the punch 21 and the receiving component 23 in the vertical direction do not intersect with the receiving component 23. When the receiving component 23 descends from the third position to the fourth position, it maintains the first state. When the receiving component 23 descends to the fourth position, the punch 21 continues to descend and drives the receiving component 23 to switch to the second state through the rivet head.

[0065] Specifically, the receiving part 23 is connected to the machine base 1 through the elastic connector, and the receiving part 23 overcomes the elastic force of the elastic connector when switching from the first state to the second state.

[0066] Reference Figure 6-7 As shown, the receiving component 23 has a receiving groove 231 on one side in the horizontal direction. The receiving groove 231 is vertically connected at both ends and is divided into a head section 2311 and a rod section 2312 distributed vertically. When the receiving component 23 is in the third position, the receiving groove 231 connects with the outlet of the discharge channel 413. The receiving groove 231 is located on the side of the receiving component 23 near the transfer seat 41. The head section 2311 and the rod section 2312 are designed to stably receive the rivets output from the transfer seat 41 and keep the rivets in this position to achieve rivet positioning.

[0067] Reference Figure 6-7 As shown, the receiving component 23 includes two splicing components 232 distributed in the horizontal direction, and each of the two splicing components 232 is provided with a partial receiving groove 231. The two splicing components 232 are respectively connected to the machine base 1 through elastic connectors. When the two connectors move away from each other in the horizontal direction, they overcome the elastic force of the elastic connectors. In the first state, the two splicing components 232 are spliced ​​to form a complete receiving groove 231. When the receiving component 23 switches to the second state, the two connectors overcome the elastic force of the elastic connectors and move away from each other. It is suitable that when the receiving component 23 descends to the fourth position, the punch 21 continues to descend and drives the two connectors to overcome the elastic force of the elastic connectors and move away from each other through the rivet head.

[0068] Reference Figure 6-7As shown, specifically in this embodiment, two splicing components 232 are distributed in the first direction, and the elastic connector is an elastic connecting piece 28. The two ends of the elastic connecting piece 28 are respectively connected to the mounting base 25 and the splicing component 232. The elastic connecting piece 28 can elastically deform in the first direction, thereby causing the two splicing components 232 to move closer or further away from each other along the first direction.

[0069] When the elastic connecting piece 28 is not deformed, the two splicing pieces 232 are attached to each other and spliced ​​to form a complete receiving groove 231. At this time, the receiving piece 23 is in the first state, which can stably support the rivet and be driven down by the rivet. When the receiving piece 23 reaches the fourth position, the limiting block 251 and the limiting screw 27 located below abut against each other. As the punch 21 continues to descend, it applies pressure to the rivet. The rivet head applies pressure to the two splicing pieces 232, causing the two splicing pieces 232 to overcome the elastic force of the elastic connecting piece 28 and move away from each other. The receiving groove 231 separates from the middle until the rivet can pass vertically downward through the receiving groove 231 and detach from the receiving piece 23. The punch 21 also passes through the receiving groove 231. The rivet passes through the riveting hole on the product on the lower operating table 12 and abuts against the lower die 22. The punch 21 and the lower die 22 cooperate to squeeze and deform the rivet, thereby riveting it to the product.

[0070] Reference Figure 7 As shown, in order to enable the two splicing parts 232 to move away from each other under the pressure of the rivet head, the bottom surface of the head section 2311 of the receiving groove 231 is provided with a guide groove 233 that connects to the rod section 2312. The diameter of the guide groove 233 gradually decreases from top to bottom. Specifically, in the design, the guide groove 233 is adapted to the rivet head. When the rivet head is in the receiving groove 231, it is embedded in the guide groove 233. The guide groove 233 makes the contact surface between the rivet head and the two splicing parts 232 inclined. Thus, under the pressure of the rivet head, the horizontal component force generated by the inclined surface causes the two splicing parts 232 to move away from each other, ensuring that the receiving part 23 can switch to the second state under the rivet pressure, and ensuring that the rivet can disengage from the receiving part 23 to complete the riveting.

[0071] Reference Figure 6-7 As shown, in this embodiment, the receiving component 23 is block-shaped, and a guide hole 234 is provided on the top surface of the receiving component 23. The guide hole 234 is connected to the head section 2311 of the receiving groove 231. When the receiving component 23 is in the first state, the guide hole 234 is a hole with the axis of the punch 21 coaxial and vertical. The punch 21 passes through the guide hole 234 so as to guide and limit the punch 21 through the guide hole 234.

[0072] Reference Figure 1 and Figure 8As shown, in some embodiments, a hardware feeding mechanism 5 can be provided on the machine base 1. The hardware feeding mechanism 5 feeds the hardware parts one by one to the stamping station, and the rivet is located directly above the hardware parts fed to the stamping station when it is output from the transfer seat 41, so that it passes through the riveting hole on the hardware parts when it descends and carries the hardware parts down to the product being processed to complete the riveting. Specifically, taking a triangular hook as an example, the feeding assembly includes a hardware feeding vibratory plate 51, a guide cylinder 52, a slider 53 and a rotating block 54 installed on the machine base 1.

[0073] Reference Figure 8 As shown, the guide cylinder 52 is set on the platform and used for dropping the triangular hooks. The output end of the hardware feeding vibratory plate 51 is connected to the top of the guide cylinder 52. The triangular hooks output by the hardware feeding vibratory plate 51 enter the guide cylinder 52 and are stacked in sequence.

[0074] Reference Figure 8 As shown, slider 53 is mounted on machine base 1 and located below guide cylinder 52. The lower end of guide cylinder 52 outputs hooks that fall onto slider 53. Slider 53 has grooves for accommodating hooks. Slider 53 moves horizontally relative to machine base 1 to transfer the hooks to the position where the feeding block 54 grips them.

[0075] Reference Figure 5 and Figure 8 As shown, the rotating block 54 is mounted on the machine base 1 and positioned between the slider 53 and the stamping station. There is a height difference between the rotating block 54 and the slider 53. The rotating block 54 can be a horizontally positioned strip with magnetic attachments at both ends to attract hooks from the grooves on the slider 53. The rotating block 54 rotates around its central vertical axis, transferring the attracted hooks between the punch 21 and the lower die 22. Therefore, the rotating block 54 can complete the feeding of one hook every half rotation, resulting in high efficiency.

[0076] Reference Figure 8 As shown, the movement direction of slider 53 is parallel to the second direction, and a guide rail and a slide table are provided on the machine base 1 to guide slider 53. Slider 53 is installed on the slide table. The movement of slider 53 is controlled by a cylinder, while the rotation of rotating block 54 is controlled by a motor.

[0077] This enables the step-by-step feeding of hardware components, coupled with the step-by-step feeding of rivets, automating the riveting process and significantly improving production efficiency. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
