Description

Technical Field

[0001] This utility model relates to the field of linear guide rail processing technology, specifically to an adaptive positioning stamping device for linear guide rail processing. Background Technology

[0002] Drawer slides are a type of linear guide rail, referring to hardware connection components fixed to the cabinet body of furniture to allow drawers or cabinet panels to move in and out. Drawer slides are suitable for connecting drawers in wooden and steel furniture such as cabinets, furniture, filing cabinets, and bathroom cabinets. Most drawer slides have multiple holes on the outside for easy installation and subsequent use.

[0003] U-shaped slide rails are one of the most common types of slide rails. They are mostly made of stainless steel or aluminum profiles with a thickness of 2-20mm. The holes on the outside of the U-shaped slide rail are mostly made by stamping equipment. The formed U-shaped slide rail is placed in the stamping equipment, and according to the design data of the U-shaped slide rail, holes are continuously drilled from one end of the outside until all the holes of the U-shaped slide rail are completed.

[0004] However, due to the limited overall thickness of the U-shaped slide rail and the lack of rapid adaptive positioning function of traditional stamping equipment, the U-shaped slide rail is prone to deformation due to the stamping force during the hole-opening process, which in turn has an adverse effect on the finished product quality of the U-shaped slide rail. To address this, we propose an adaptive positioning stamping device for linear guide rail processing. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adaptive positioning stamping device for linear guide rail processing, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an adaptive positioning stamping device for linear guide rail processing, comprising:

[0008] The control panel has a stamped part on its top and a collection box on its bottom.

[0009] A feeding and positioning mechanism is provided on the top of the operating plate. The feeding and positioning mechanism includes a stamping forming seat, which is fixedly connected to the top of the operating plate. A through groove is provided in the middle of the top of the operating plate. A bidirectional threaded rod is movably connected to the inner side of the through groove through a bearing. Two symmetrically distributed movable blocks are threadedly connected to the outer side of the bidirectional threaded rod. A frame is fixedly connected to the top of the movable blocks. Multiple movable auxiliary rollers are provided on the inner side of the frame. A limit component is provided on the outer side of the frame.

[0010] Furthermore, a limiting rod is fixedly connected to the inner side of the through groove, and two movable blocks are slidably connected to the outer side of the limiting rod. The left and right ends of the bidirectional threaded rod are configured with reverse threads.

[0011] Furthermore, a drive motor is fixedly connected to the outside of the operating panel, and the rear end of the bidirectional threaded rod passes through the rear side of the through slot and is fixedly connected to the output shaft of the drive motor through a coupling.

[0012] Furthermore, the limiting component includes a U-shaped frame, which is fixedly connected to the outside of the frame. A return spring is fixedly connected to the top of the U-shaped frame, and a limiting wheel is fixedly connected to the other end of the return spring. A vertical rod is fixedly connected to the top of the limiting wheel, and the other end of the vertical rod passes through the top of the U-shaped frame and is slidably connected to the top of the U-shaped frame.

[0013] Furthermore, a second reset spring is fixedly connected to the inner side of the U-shaped frame, and a drive wheel is fixedly connected to the other end of the outer side of the second reset spring. A servo motor is provided on the top of the drive wheel.

[0014] Furthermore, a crossbar is fixedly connected to the outside of the drive wheel, and the other end of the crossbar passes through the U-shaped frame and is slidably connected to the U-shaped frame.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] 1. Through the setting of the feeding and positioning mechanism, the two frames and the stamping forming seat can quickly support the U-shaped slide rail from the inside when punching the U-shaped slide rail, so that it maintains the overall shape stability when punching the stamped part and will not deform during the stamping process. In addition, the two frames can move in opposite directions, thereby adaptively positioning different models of U-shaped slide rails and ensuring the production quality of U-shaped slide rails.

[0017] 2. By setting a limiting component, this utility model allows the drive wheel to cooperate with the auxiliary roller inside the frame to move the position of the U-shaped slide rail during the punching operation of the U-shaped slide rail. This enables punching at different positions. In addition, the limiting wheel limits the U-shaped slide rail from the top above the stamping forming seat, preventing displacement of the U-shaped slide rail during the return forming of the stamped part, and further preventing deformation of the U-shaped slide rail during punching.

[0026] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1:

[0029] Reference Figure 1-5This is the first embodiment of the present invention, which discloses an adaptive positioning stamping device for linear guide rail processing, comprising:

[0030] The control panel 1 has a stamped part 4 on its top and a collection box 3 on its bottom.

[0031] The stamping part 4 includes a bracket, which is fixedly connected to the top of the operating plate 1. A cylinder is provided on the bracket, and a detachable punch head is provided at the telescopic end of the cylinder.

[0032] The bottom of the control panel 1 is fixedly connected to four support legs arranged in a rectangular pattern.

[0033] The feeding and positioning mechanism 2 is located on the top of the operating plate 1. The feeding and positioning mechanism 2 includes a stamping and forming seat 22, which is fixedly connected to the top of the operating plate 1. A through groove 23 is opened in the middle of the top of the operating plate 1. A bidirectional threaded rod 24 is movably connected to the inside of the through groove 23 through a bearing. Two symmetrically distributed moving blocks 26 are threadedly connected to the outside of the bidirectional threaded rod 24. A frame 29 is fixedly connected to the top of the moving blocks 26. Multiple movable auxiliary rollers 28 are arranged inside the frame 29, and a limit component 25 is arranged outside the frame 29.

[0034] The top center of the stamping forming base 22 has a through forming hole for discharging punching debris.

[0035] A roller shaft is fixedly connected to the inner side of the auxiliary roller 28. The roller shaft is movably connected to the inner side of the frame 29 through a bearing, so that the auxiliary roller 28 can rotate within the frame 29. It works with the drive wheel 257 to transport the U-shaped slide rail and perform continuous punching.

[0036] The outer side of the auxiliary roller 28 is roughened, and the outer surface has 0.05-0.1mm of concave and convex textures, which are used to drive the U-shaped slide rail to move during the stamping of the U-shaped slide rail.

[0037] Specifically, a limit rod 27 is fixedly connected to the inner side of the through groove 23, two moving blocks 26 are slidably connected to the outer side of the limit rod 27, the left and right ends of the bidirectional threaded rod 24 are set with reverse threads, a drive motor 21 is fixedly connected to the outer side of the operating plate 1, the rear end of the bidirectional threaded rod 24 passes through the rear side of the through groove 23 and is fixedly connected to the output shaft of the drive motor 21 through a coupling.

[0038] The limiting rod 27 limits the two moving blocks 26 to ensure that they can only move in opposite directions when the bidirectional threaded rod 24 rotates. The reverse thread setting can drive the two moving blocks 26 to move in opposite directions when it rotates. The drive motor 21 can drive the bidirectional threaded rod 24 to rotate through the output shaft, thereby providing power for the rotation of the bidirectional threaded rod 24.

[0039] Example 2:

[0040] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0041] The limiting component 25 includes a U-shaped frame 253, which is fixedly connected to the outside of the frame 29. A return spring 254 is fixedly connected to the top of the U-shaped frame 253. The other end of the return spring 254 is fixedly connected to a limiting wheel 255. A vertical rod 251 is fixedly connected to the top of the limiting wheel 255. The vertical rod 251 is rectangular. The other end of the vertical rod 251 passes through the top of the U-shaped frame 253 and is slidably connected to the top of the U-shaped frame 253.

[0042] The limiting wheel 255 and the return spring 254 limit the movement of the U-shaped slide rail from the top to prevent the punch head from displacing the U-shaped slide rail during the return stroke, thereby ensuring punching accuracy. The vertical rod 251 limits the movement trajectory of the limiting wheel 255 to ensure that it can only move in the up and down direction.

[0043] Specifically, a second return spring 258 is fixedly connected to the inner side of the U-shaped frame 253, and a drive wheel 257 is fixedly connected to the other end of the outer side of the second return spring 258. A servo motor 252 is provided on the top of the drive wheel 257, and a crossbar 256 is fixedly connected to the outer side of the drive wheel 257. The other end of the crossbar 256 passes through the U-shaped frame 253 and is slidably connected to the U-shaped frame 253.

[0044] The reset spring 258 and the drive wheel 257 can work with the auxiliary roller 28 to drive the U-shaped slide rail, so that it can move on the stamping forming seat 22, making it easier for the U-shaped slide rail to move to the next punching position, thereby performing continuous punching operation on the U-shaped slide rail, while avoiding displacement of the U-shaped slide rail during punching.

[0045] The remaining structure is the same as that in Example 1.

[0046] The workflow of this utility model is as follows:

[0047] One end of the U-shaped slide rail that needs to be punched is aligned with the stamping forming seat 22 and pushed in. The drive motor 21 drives the bidirectional threaded rod 24 to rotate through the output shaft, thereby driving the two frames 29 to move in opposite directions until the auxiliary roller 28 on the side of the two frames 29 that is far away from each other fits against the inner wall of the U-shaped slide rail, thus completing the adaptive positioning of the U-shaped slide rail.

[0048] The servo motor 252 drives the drive wheel 257 to rotate through the output shaft, and cooperates with the auxiliary rollers 28 on both sides to transport the U-shaped slide rail outside the stamping forming seat 22 until the first punching position of the U-shaped slide rail is below the punching head.

[0049] At this time, the cylinder extends and pushes the punch head downward to punch the outside of the U-shaped slide rail. The debris generated by punching enters the collection box 3 below through the through groove 23. When the punch head returns, the limiting wheel 255 limits it from the top of the U-shaped slide rail.

[0050] Drive wheel 257 continues to work, driving the U-shaped slide rail to move and punch the next hole until all holes are punched.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
