Description

Technical Field

[0001] The invention relates to the technical field of bending equipment, and in particular to a forming equipment for processing a computer keyboard bracket. Background Art

[0002] A computer keyboard stand is an important mounting component that is usually located inside a laptop keyboard to support and secure the keys. Its main function is to ensure that each key is stable and has proper elastic feedback during use, thereby improving the user's typing experience and the durability of the keyboard.

[0003] When a traditional workpiece bending machine is bending a workpiece, the workpiece itself has a certain resilience due to its own material characteristics, which makes the actual bending angle often smaller than the target angle. For example, when the workpiece is required to be bent 90 degrees, the workpiece is generally bent to more than 80 degrees during the bending process, and then the workpiece rebounds to reach the required 90 degrees. The existing workpiece bending equipment has a combination structure of a three-quarter cylinder and a clamp. During the bending process of the workpiece, there is relative movement between the three-quarter cylinder and the clamp. As the processing continues, the long-term relative movement will inevitably cause wear on the accuracy of the entire equipment. The decline in equipment accuracy will directly affect the accuracy and consistency of the workpiece bending, resulting in unstable product quality and increased scrap rate. In addition, when bending different batches of workpieces, due to the possible differences in their degree of rebound, the operator needs to make repeated adjustments during bending to achieve the expected angle requirements. This frequent adjustment operation is not only cumbersome and time-consuming, but also greatly reduces production efficiency. Summary of the invention

[0023] like Figures 1 to 6 As shown, an embodiment of the present invention provides a forming device for processing a computer keyboard bracket, which includes a bracket 110, a rotating arc plate 150, a tightening block 210 and an adjustment component.

[0024] The support platform 120 is provided on the bracket 110. The support platform 120 has a horizontal upper end surface. The profile of the support platform 120 is slightly trapezoidal, and the workpiece can be placed on the support platform 120. The bracket 110 is provided with a mounting block 130. The mounting block 130 is arranged directly above the support platform 120. The bracket 110 is provided with a driving member, which is used to drive the mounting block 130 to approach or move away from the support platform 120. In the initial state, the mounting block 130 is in a state of moving away from the support platform 120. When the workpiece is bent, the driving member drives the mounting block 130 to approach the support platform 120. After the workpiece is bent, the driving member can drive the mounting block 130 away from the support platform 120. For example, the driving member is a driving cylinder 140, which is vertically arranged. The upper end of the driving cylinder 140 is fixedly connected to the bracket 110, and the lower end of the driving cylinder 140 is fixedly connected to the mounting block 130. The length change of the driving cylinder 140 can control the mounting block 130 to approach or move away from the support platform 120.

[0025] The axis of the rotating arc plate 150 is arranged horizontally. Specifically, the rotating arc plate 150 is a partially cylindrical sleeve-shaped structure. The outer side wall of the rotating arc plate 150 is rotatably connected to the mounting block 130, so that the rotating arc plate 150 is rotatably connected to the mounting block 130 around its own axis. A reset member is arranged between the rotating arc plate 150 and the mounting block 130, and the reset member is used to drive the rotating arc plate 150 to return to the initial state after the rotating arc plate 150 rotates. The rotating arc plate 150 is coaxially rotatably connected with the extrusion arc plate 160, and the extrusion arc plate 160 has resistance when rotating relative to the rotating arc plate 150. Specifically, the cross-sectional curvature of the extrusion arc plate 160 is the same as the cross-sectional curvature of the rotating arc plate 150, and the axis corresponding to the extrusion arc plate 160 is the same as the axis corresponding to the rotating arc plate 150. In the initial state, the extrusion arc plate 160 overlaps the rotating arc plate 150 by a first preset length.

[0026] The top tightening block 210 is connected to the mounting block 130 in a sliding manner up and down. In the initial state, the mounting block 130 is directly above the support platform 120. A plug-in rod is fixedly provided on the top tightening block 210, and a plug-in slot is provided on the mounting block 130. The plug-in rod is slidably connected to the plug-in slot, and the plug-in rod cannot be separated from the plug-in slot. In the initial state, the top tightening block 210 is in a state of not abutting the mounting block 130. A horizontal top tightening plate 220 is slidably provided on the top tightening block 210. Specifically, the top tightening block 210 is slidably connected to the top tightening plate 220. The top tightening plate 220 is always in a horizontal state. The lower end surface of the top tightening plate 220 and the lower end surface of the top tightening block 210 are at the same horizontal height. The top tightening plate 220 is slidably connected to the top tightening block 210, and the top tightening plate 220 always abuts against one of the edges of the rotating arc plate 150. In the process of the mounting block 130 approaching the support platform 120, the clamping block 210 and the clamping plate 220 gradually contact the side wall of the workpiece, and the extrusion arc plate 160 contacts the workpiece at the same time. As the mounting block 130 further approaches the support platform 120, the plug-in rod on the clamping block 210 slides in the plug-in groove. At the same time, the extrusion arc plate 160 squeezes the workpiece. There is a rotational resistance between the extrusion arc plate 160 and the rotating arc plate 150, and a small relative rotation occurs between the extrusion arc plate 160 and the rotating arc plate 150. When the rotating arc plate 150 rotates on the mounting block 130, the edge of the rotating arc plate 150 pushes the clamping plate 220, so that the clamping plate 220 slides horizontally on the clamping block 210.

[0027] The adjustment assembly is used to adjust the rotation resistance between the extrusion arc plate 160 and the rotation arc plate 150 . Specifically, when bending the first workpiece of the same batch, the workpiece to be bent is placed on the support table 120, and the driving member drives the mounting block 130 to approach the support table 120, and the clamping block 210 and the clamping plate 220 gradually contact the workpiece. When the clamping block 210 and the clamping plate 220 contact the workpiece, the extrusion arc plate 160 contacts the workpiece. In the initial state, there is a large resistance to relative rotation between the extrusion arc plate 160 and the rotating arc plate 150. As the mounting block 130 approaches the support table 120, the clamping block 210 slides on the mounting block 130, and the clamping plate 220 is pushed by the rotating arc plate 150 to slide on the clamping block 210. At the same time, the extrusion arc plate 160 and the rotating arc plate 150 undergo a small relative rotation. The first workpiece of the same batch is bent to the first target angle. When the workpiece is bent and rebounds, the adjustment component adjusts the rotational resistance between the extrusion arc plate 160 and the rotating arc plate 150. After the workpiece rebounds, the workpiece may not be able to fully reach the required angle. ; Subsequently, the second workpiece of the same batch is bent. At this time, the relative rotation amplitude of the extrusion arc plate 160 and the rotating arc plate 150 increases, and the second workpiece of the same batch is bent to the second target angle. When the workpiece is bent and rebounds, the adjustment component adjusts the rotational resistance between the extrusion arc plate 160 and the rotating arc plate 150 again. After the workpiece rebounds, the workpiece may not be able to fully reach the required angle; until the Nth workpiece of the same batch is bent. At this time, the relative rotation amplitude of the extrusion arc plate 160 and the rotating arc plate 150 is further increased, and the Nth workpiece of the same batch is bent to the Nth target angle. When the workpiece is bent and rebounds, the adjustment component cannot adjust the rotational resistance between the extrusion arc plate 160 and the rotating arc plate 150. In this state, after the workpiece rebounds, the workpiece can reach the required angle. When the workpieces of the same batch are continuously bent subsequently, the adjustment component no longer adjusts the rotational resistance between the extrusion arc plate 160 and the rotating arc plate 150. By setting the adjustment component to adjust the rotational resistance between the extrusion arc plate 160 and the rotating arc plate 150 when the workpiece rebounds, until the workpiece reaches the required angle after bending and rebounding, during this process, the clamping plate 220 will not cause wear between the rotating arc plate 150, thereby improving the service life of the clamping plate 220 and the rotating arc plate 150. At the same time, when bending different batches of workpieces, the rotational resistance between the extrusion arc plate 160 and the rotating arc plate 150 can be restored to the initial state by using the adjustment component without the need for cumbersome operations, thereby improving production efficiency.

[0028] In one embodiment, a damping member is provided between the rotating arc plate 150 and the extruding arc plate 160, and the resistance of the damping member can be adjusted by an adjustment component. Specifically, the resistance of the damping member is set to a maximum resistance state in the initial state. When the first workpiece of the same batch is bent, the damping of the damping member is in a maximum resistance state, and the adjustment component can adjust the resistance of the damping member according to the rebound condition of the workpiece.

[0029] In one embodiment, the damping member includes a connecting frame 230, a damping cylinder 240 and a transmission mechanism. The connecting frame 230 is fixedly connected to the rotating arc plate 150. The damping cylinder 240 has a fixed section and a telescopic section 241. The telescopic section 241 is coaxially slidably connected with the fixed section. The telescopic section 241 has resistance when sliding relative to the fixed section. The transmission mechanism is used to transfer the rotation of the extrusion arc plate 160 relative to the rotating arc plate 150 to the sliding of the telescopic section 241 relative to the fixed section. In the initial state, the damping cylinder 240 is in a state of maximum resistance, and the relative rotation of the extrusion arc plate 160 and the rotating arc plate 150 is in a state of greatest difficulty. However, when the first workpiece of the same batch is bent, the extrusion arc plate 160 and the rotating arc plate 150 can still have a relatively small relative movement.

[0030] In one embodiment, the fixed section has a damping cavity inside, and the damping cavity is filled with damping fluid. The fixed section is fixedly connected to the connecting frame 230, and the telescopic section 241 is coaxially arranged with the fixed section, and one end of the telescopic section 241 is always in the damping cavity. The end of the telescopic section 241 in the damping cavity is provided with a first damping disc 250 and a second damping disc 260, and the first damping disc 250 is slidably arranged in the damping cavity, and the first damping disc 250 is provided with a first drainage hole 251. The second damping disc 260 is fixedly connected to the end of the telescopic section 241, and is rotatably connected to the first damping disc 250, and can rotate and slide in the damping chamber; the second damping disc 260 is provided with a plurality of second drainage holes, and initially set, the first drainage hole 251 on the first damping disc 250 is completely blocked by the second damping disc 260, and the plurality of second drainage holes on the second damping disc 260 are completely blocked by the first damping disc 250, at which time, the sliding resistance of the telescopic section 241 relative to the fixed section is in the maximum state. The adjustment component can adjust the rotation of the telescopic section 241 inside the fixed section, thereby changing the number of the plurality of second drainage holes blocked by the first damping disc 250. When the first workpiece of the same batch is bent, the damping fluid in the damping chamber can flow through the gap between the first damping disc 250, the second damping disc 260 and the inner wall of the fixed section, so that the extrusion arc plate 160 and the rotating arc plate 150 can still have a relatively small range of movement.

[0031] In one embodiment, the transmission mechanism includes a transmission roller 310 and a transmission bar 320; the transmission roller 310 is rotatably connected to the connecting frame 230, and the transmission roller 310 is always in contact with the extrusion arc plate 160. When the extrusion arc plate 160 rotates relative to the rotating arc plate 150, the transmission roller 310 can rotate. The transmission bar 320 is slidably connected to the connecting frame 230, the transmission bar 320 always abuts against the transmission roller 310, the transmission bar 320 is rotationally connected to the telescopic section 241, and when the transmission bar 320 slides relative to the connecting frame 230, it drives the telescopic section 241 to slide relative to the fixed section. Further, the transmission bar 320 is bent and slidably connected to the connecting frame 230. When the transmission roller 310 rotates, the transmission bar 320 slides on the connecting frame 230, and when the transmission bar 320 slides on the connecting frame 230, it drives the telescopic section 241 to slide relative to the fixed section, thereby realizing the transmission of the rotation of the extrusion arc plate 160 relative to the rotating arc plate 150 to the sliding of the telescopic section 241 relative to the fixed section.

[0032] In one embodiment, a fixed tooth sleeve is provided on the transmission roller 310, and a fixed tooth groove is provided on the extrusion arc plate 160. The fixed tooth sleeve on the transmission roller 310 is always meshed with the fixed tooth groove on the extrusion arc plate 160; the transmission bar 320 is set as a rack, and the teeth on the transmission bar 320 are always meshed with the fixed tooth sleeve on the transmission roller 310. By setting the transmission between the transmission roller 310, the extrusion arc plate 160, and the transmission bar 320 as the meshing transmission between the tooth grooves, the linkage between the transmission roller 310, the extrusion arc plate 160, and the transmission bar 320 is ensured, and the situation that the transmission roller 310 rotates alone on the connecting frame 230 is avoided.

[0033] In one embodiment, the adjustment assembly includes an adjustment spring 330, an adjustment plate 340 and an adjustment roller 350; the adjustment spring 330 is arranged between the tightening plate 220 and the tightening block 210. In the initial state, the adjustment spring 330 is in the original length state, and the tightening plate 220 is in a state away from the tightening block 210; further, the tightening block 210 is provided with a mounting groove, the mounting groove is horizontally arranged, and the tightening plate 220 is provided with a horizontal connecting rod, the connecting rod is inserted into the mounting groove, and the adjustment spring 330 is sleeved on the connecting rod, one end of the adjustment spring 330 is connected to the tightening block 210, and the other end of the adjustment spring 330 is connected to the tightening plate 220. The adjustment plate 340 is slidably disposed on the connecting frame 230, and the adjustment roller 350 is fixedly connected to the telescopic section 241 of the damping cylinder 240. The adjustment roller 350 is always in contact with the adjustment plate 340. When the adjustment plate 340 slides on the connecting frame 230, the adjustment roller 350 can rotate to change the number of the second drainage holes blocked by the first damping disk 250. Furthermore, in the process of bending the workpiece, the rotating arc plate 150 rotates on the workpiece, and the rotating arc plate 150 squeezes and pushes the tightening plate 220, so that the adjustment spring 330 is gradually compressed. After the workpiece is bent, it rebounds. During the rebound process, the workpiece continues to push the extrusion arc plate 160. At this time, the extrusion arc plate 160 still rotates relative to the rotating arc plate 150. If the workpiece does not reach the required angle after rebounding, the workpiece no longer pushes the extrusion arc plate 160, and the rotating arc plate 150 no longer squeezes the tightening plate 220. The adjustment spring 330 quickly resets. The adjustment spring 330 pushes the tightening plate 220 to quickly reset. When the tightening plate 220 resets, it collides with the adjustment plate 340, so that the adjustment plate 340 slides on the connecting frame 230. When the adjustment plate 340 slides on the connecting frame 230, it drives the adjustment roller 350 to rotate. The adjustment roller 350 drives the telescopic section 241 to rotate synchronously, thereby changing the number of the second drainage holes blocked by the first damping disk 250, thereby reducing the resistance of the telescopic section 241 and the fixed section when sliding relative to each other.

[0034] In one embodiment, the reset member includes a reset torsion spring, which is arranged between the rotating arc plate 150 and the mounting block 130. In the initial state, the reset torsion spring is in the initial state. When there is relative rotation between the rotating arc plate 150 and the mounting block 130, the reset torsion spring gradually accumulates force. After the bending of a workpiece is completed, when the driving cylinder 140 drives the mounting block 130 away from the support platform 120, the reset torsion spring drives the rotating arc plate 150 to reset on the mounting block 130.

[0035] In one embodiment, an extrusion strip 161 is fixedly provided on the extrusion arc plate 160, and the extrusion strip 161 can abut against the workpiece. Specifically, the material of the extrusion strip 161 is different from the material of the extrusion arc plate 160, and the hardness of the extrusion strip 161 is greater than the hardness of the extrusion arc plate 160. By providing the extrusion strip 161, the curling phenomenon of the extrusion arc plate 160 is reduced.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
