Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 10The present invention preferably provides a hardware riveting mechanism, comprising: a frame 1; a mold base 2, which is movably mounted on the frame 1, and has riveting heads 3 and a plurality of guide plates 4 respectively at its lower end, wherein there are at least two riveting heads 3, and the plurality of guide plates 4 are arranged at intervals along the same horizontal direction between the two riveting heads 3, and a V-shaped guide groove 5 is recessed at the lower end of the guide plate 4; a cutting member 6, which is mounted on the mold base 2 and located on opposite sides of the two riveting heads 3, for cutting the wire; a driving member 7, which is mounted on the frame 1, for driving the riveting heads 3 to move up and down reciprocally; and an adjusting member 8, which is mounted on the mold base 2 and connected to one of the guide plates 4, for driving the corresponding guide plate 4 to adjust its displacement longitudinally.

[0017] Specifically, such as Figure 10 As shown, multiple metal sheets 101 are conveyed longitudinally to the riveting head of the mold base, and wires 102 pass through the multiple metal sheets laterally and are placed in the V-shaped guide grooves of several guide plates. According to the requirements, the position of the guide plates is adjusted by the adjusting component, so that the longitudinal displacement of one of the guide plates forces the wires located in its V-shaped guide groove to be pulled and displaced, thereby changing the length of the wires. Then, the driving component is activated to drive the mold base to move down, and the riveting head completes the riveting. At the same time, the cutting component cuts the wires, and the mold base moves up and resets, completing one work cycle.

[0018] Furthermore, the adjustment component 8 includes a depth micrometer 81 and an adjustment seat 82. The adjustment seat 82 is movably disposed on the mold base 2 along the longitudinal direction. The guide plate 4 is disposed on one side of the adjustment seat 82. The depth micrometer 81 is fixedly disposed on one side of the mold base 2 and its measuring axis is connected to the adjustment seat 82.

[0019] Specifically, the depth micrometer is a relatively mature existing technology, and its structural principle will not be described in detail here. It is equivalent to Chinese Patent Publication No. CN217303765U. By rotating the knob of the depth micrometer, its measuring axis pushes or pulls the adjustment seat to move along the longitudinal track of the mold base, and the adjustment seat drives the guide plate to move synchronously. The displacement of the guide plate is precisely controlled by the scale of the micrometer. After reaching the desired position, the micrometer is locked to complete the adjustment.

[0020] Furthermore, the lower end of the mold base 2 has a recessed groove 83, and one side of the mold base 2 is provided with a first movable groove 84 communicating with the groove 83. The adjusting seat 82 is movably disposed in the first movable groove 84. One side of the adjusting seat 82 is located in the recessed groove 83 with a second movable groove 85. The guide plate 4 is movably disposed in the second movable groove 85. One side of the guide plate 4 is provided with a fixed shaft 100. The lower end of the groove 83 is provided with a limiting block 87. The fixed shaft 100 is limited and abuts against the upper side of the limiting block 87. The upper end of the guide plate 4 in the groove 83 abuts against a first spring 88. Specifically, the guide plate is prevented from moving excessively downward by contacting the fixed shaft and the limiting block; when the adjusting seat moves, the guide plate moves longitudinally within the groove; when the mold base moves downward, the guide plate first contacts the base located on the outside for fixing the metal sheet, and the guide plate compresses the first spring upward. The elastic force of the first spring buffers the contact impact. At this time, the wire is located in the V-shaped guide groove of the guide plate. The wire is guided and aligned through the V-shaped guide groove, and the guide plate can pull the wire by adjusting the displacement of the adjusting component to achieve the purpose of adjusting the wire length between adjacent metal sheets. When the riveting is completed, when the mold base moves upward, the first spring resets and pushes the guide plate back to the initial position.

[0021] Furthermore, the lower end of the mold base 2 has a plurality of first vertical guide grooves 21 recessed therein. The riveting heads 3 are correspondingly and movably disposed within the first vertical guide grooves 21. A first connecting groove 22 communicating with the first vertical guide grooves 21 is opened through one side of the mold base 2. A first connecting block 98 is detachably connected to the first connecting groove 22. A first limiting groove 23 is recessed on one side of the riveting head 3, and one end of the first connecting block 98 is fitted into the first limiting groove 23. Specifically, during installation, the riveting head is placed into the first vertical guide groove, aligning the first limiting groove with the first connecting groove, and the first limiting block is inserted and fixed. During operation, the riveting head moves up and down within the groove, and the first limiting block acts as a guide and limit. During replacement, the riveting head can be removed by removing the first limiting block. The first limiting block is detachably fixed to the mold base by bolts.

[0022] Furthermore, the length of the first limiting groove 23 is greater than the end width of the first connecting block 98, so that the riveting head 3 can move up and down relative to the first connecting block 98 along the first vertical guide groove 21. The mold base 2 is provided with a second horizontal groove 24 that communicates with the first vertical guide groove 21. A movable rod 25 is movably arranged in the second horizontal groove 24. The movable rod 25 is located at the upper end of the riveting head 3. A first plane 26 and a first inclined plane 27 that can abut against the upper end of the riveting head 3 are respectively provided on the lower side of the movable rod 25. One end of the movable rod 25 extends to the outside of the mold base 2 and is provided with a connecting seat 28. The connecting seat 28 is provided with a tightening screw (not shown in the figure) and a connecting screw (not shown in the figure). The connecting screw (not shown in the figure) passes through the connecting seat and is threadedly connected to the mold base 2. The tightening screw (not shown in the figure) is threadedly inserted into the connecting seat 28 and one end abuts against one side of the mold base 2.

[0023] Specifically, a connecting screw passes through the connecting seat and is threadedly connected to the mold base, so that the connecting screw is in a connected state of pressing the connecting seat. Then, a tightening screw is threadedly inserted into the connecting seat, with one end abutting against one side of the mold 2, so that a top-pull adjustment structure is formed between the connecting seat and the mold base. After loosening the screw, the connecting seat is moved, which drives the movable rod to move in the second transverse groove, so that the first plane or the first inclined surface contacts the upper end of the riveting head, and its initial height is adjusted, thereby adjusting the riveting pressing accuracy of the riveting head pressing against the metal sheet. After adjustment, the connecting screw and the tightening screw are tightened respectively to fix the movable rod. During riveting, the riveting head moves up and down along the groove to ensure stable movement.

[0024] Furthermore, a bending head 29 is also provided on the mold base 2 corresponding to one side of the riveting head 3, and the lower end of the bending head 29 is respectively provided with a second plane 30 and a second inclined surface 31. Specifically, as shown... Figure 10 As shown, when the mold base moves down, the bending head moves down accordingly. According to the processing requirements, the second inclined surface contacts the bending area 103 of the metal sheet 101 and applies force to bend it, or the second plane contacts the metal sheet to flatten and press it; when the mold base moves up, the bending head moves up and resets accordingly.

[0025] Furthermore, the lower end of the mold base 2 has a recessed second vertical guide groove 32, and the bending head 29 is movably disposed within the second vertical guide groove 32. A second connecting groove 33, communicating with the second vertical guide groove 32, is provided through one side of the mold base 2. A second limiting block 99 is detachably connected within the second connecting groove 33. A second limiting groove 34 is recessed on one side of the bending head 29, and one end of the second limiting block 99 is fitted into the second limiting groove 34. Specifically, during installation, the bending head is placed into the second vertical guide groove, aligned with the second limiting groove and the second connecting groove, and the second limiting block is inserted and fixed. During operation, the bending head moves along the groove, with the second limiting block acting as a guide. For replacement, the bending head can be removed by removing the second limiting block.

[0026] Furthermore, the length of the second limiting groove 34 is greater than the end width of the second limiting block 99, so that the bending head 29 can move up and down relative to the second limiting block 99 along the second vertical guide groove 32. A second spring 35 is located in the second vertical guide groove 32 at the upper end of the bending head 29. Specifically, when the mold base moves down, the bending head contacts the workpiece and compresses the second spring upward, and the spring force buffers the impact; when the mold base moves up, the second spring resets and pushes the bending head down to its initial position, and the second limiting block ensures the stability of its movement trajectory.

[0027] Furthermore, the cutting component 6 includes a cylinder 61 and a movable seat 62 mounted on the drive shaft of the cylinder 61. A cutting blade 53 is mounted on the movable seat 62, and the cutting blade 53 can move longitudinally relative to the mold base 2 along with the movable seat 62. Specifically, upon completion of riveting, the cylinder drive shaft extends, driving the movable seat and the cutting blade to move longitudinally, and the cutting blade cuts the wire; after cutting, the drive shaft retracts, causing the cutting blade to reset, awaiting the next action.

[0028] Furthermore, the driving component 7 includes a motor 71, a turntable 72, a rocker arm 73, and a connecting rod 74. The motor 71 is mounted on the frame 1. The turntable 72 is rotatably mounted on the frame 1 and connected to the drive shaft of the motor 71. The connecting rod 74 is vertically movable on the frame 1. The rocker arm 73 is hinged between the connecting rod 74 and the turntable 72, and the hinge point between the rocker arm 73 and the turntable 72 is offset relative to the center of the turntable 72. The mold base 2 is located at the lower end of the connecting rod 74. Specifically, after the motor starts, the turntable rotates, and the rocker arm, due to the eccentricity of the hinge point, drives the connecting rod to move up and down. The connecting rod drives the mold base to move synchronously, enabling the riveting head to complete periodic riveting actions and achieve continuous processing.
