Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a bending machine large-size processing anti-pressure deviation mechanism. Background Technology

[0002] A bending machine is a machine capable of bending thin plates. Its structure mainly includes a support, a worktable, and a clamping plate. The worktable is placed on the support and consists of a base and a pressure plate. The base is connected to the clamping plate via a hinge. The base consists of a housing, a coil, and a cover plate. The coil is placed in a recess in the housing, and the top of the recess is covered by the cover plate. During operation, the coil is energized by a wire, which generates an attractive force on the pressure plate, thereby clamping and bending the thin plate between the pressure plate and the base. However, when bending large plates, two operators usually simultaneously pick up the thin plate and place it into the bending machine. During the bending process, there is no limit or fixation for the plate, which can easily lead to positional shifts or instability in large plates, affecting bending accuracy and the quality of the bent plate. Furthermore, handling large plates is inconvenient, making the operation more difficult. Utility Model Content

[0013] The second movable block has its bottom slidably connected to the inside of the first sliding groove.

[0014] Furthermore, a rubber dust cover is bonded and fixed between the bearing shell and the bearing plate.

[0015] Furthermore, the limiting mechanism includes:

[0016] A connecting shell is disposed on the top of the bearing plate. Both ends of the connecting shell are screwed with multiple fixing bolts, and movable block one and movable block two are screwed with the corresponding fixing bolts respectively.

When the plate is bent, the pushing component causes the support plate to move up and deflect, and moves with the support plate.

It is more convenient to use, and the material support mechanism makes it easy to place and push large-sized boards, reducing the labor intensity of the workers. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] Please see Figure 1-6 In this embodiment of the utility model, a large-size processing anti-pressure deviation mechanism for a bending machine includes: a material support mechanism 200 and a limiting mechanism 300. The material support mechanism 200 includes a bearing shell 210, a bearing plate 220 is provided on the top of the bearing shell 210, and a pushing component is provided on the bottom of the bearing plate 220. A roller 223 is rotatably connected to the bearing plate 220. A first sliding groove 221 and a second sliding groove 222 are provided on the bearing plate 220, and an adjustment component is provided on the bearing plate 220. The limiting mechanism 300 is provided on the bearing plate 220 to prevent deviation during bending of large-size plates.

[0039] Specifically, by installing the anti-pressure deviation mechanism for large-size processing of the bending machine on one side of the bending machine body 100, the bearing plate 220 is brought close to the bending machine body 100. When the large-size sheet is placed on top of the bearing plate 220, multiple rollers 223 are used to facilitate the movement of the sheet. The position of the limiting mechanism 300 is adjusted using the adjusting component, and the limiting mechanism 300 is used to limit the sheet. When the bending machine body 100 bends the sheet, the pushing component pushes the bearing plate 220, the limiting mechanism 300, and the sheet to move, so that the material support mechanism 200 and the limiting mechanism 300 can move with the bending of the sheet to support and limit it, thereby preventing the large-size sheet from deviating during bending and ensuring the quality of the processed sheet.

[0040] like Figure 5-6 As shown, in this embodiment, the pushing component includes: electric cylinder 240 and electric cylinder 250. Electric cylinder 240 is fixedly connected to one end of the inner bottom surface of the bearing shell 210, and electric cylinder 250 is disposed at the other end inside the bearing shell 210. Rotating blocks 260 are fixedly connected to the output end and bottom of electric cylinder 250 and the output end of electric cylinder 240, respectively. Fixed seats 261 are rotatably connected to the outer sides of rotating blocks 260. The bottom of the bearing plate 220 and the inner bottom surface of the bearing shell 210 are respectively fixedly connected to the corresponding fixed seats 261. The adjusting component includes: stepper motor 270 and moving block 280. Stepper motor 270 is fixedly connected to one inner sidewall of slide groove 222. A screw 271 is fixedly connected to the output end of stepper motor 270, and a moving block 272 is screwed onto the outer side of the screw 271. The bottom of moving block 272 is slidably connected to the inside of slide groove 222, and the bottom of moving block 280 is slidably connected to slide groove 222. 1. The internal sliding connection and limiting mechanism 300 includes: a connecting shell 310, two moving plates 320, a bidirectional lead screw 340, and a second stepper motor 350. The connecting shell 310 is located on the top of the bearing plate 220. Both ends of the connecting shell 310 are screwed with multiple fixing bolts 311, and the first moving block 272 and the second moving block 280 are respectively screwed with the corresponding fixing bolts 311. Moving components are provided on both sides of the connecting shell 310. The tops of the two moving plates 320 are slidably connected to the inside of the connecting shell 310. A connecting notch is opened at the bottom of one side of the moving plate 320, and multiple rotating rods 321 are rotatably connected inside the connecting notch. The two moving plates 320 are opposite to each other. The bidirectional lead screw 340 is rotatably connected to the inside of the connecting shell 310. The second stepper motor 350 is fixedly connected to the connecting shell 310. The output end of the second stepper motor 350 passes through the side wall of the connecting shell 310 and is fixedly connected to one end of the bidirectional lead screw 340.

[0041] In this embodiment, when the sheet metal is placed on multiple rollers 223 and the portion of the sheet metal to be bent moves between the upper and lower dies of the bending machine body 100, stepper motor 270 is started, driving screw 271 to rotate, thereby moving moving block 272, which in turn moves limiting mechanism 300. Once limiting mechanism 300 reaches the appropriate position, stepper motor 350 is started to rotate forward, driving bidirectional lead screw 340 to rotate, causing two moving plates 320 to move towards each other. This causes multiple rotating rods 321 to contact both sides of the sheet metal, limiting its movement. The rotating rods 321 do not affect... The sheet metal moves back and forth. When the sheet metal is bent, the electric cylinder 240 is activated to extend it, causing the support plate 220 to move upward a certain distance. The electric cylinder 250 is then activated to extend it. The extended electric cylinder 250 pushes the corresponding rotating block 260, the fixed seat 261, and the other end of the support plate 220, causing the support plate 220 to deflect. This causes the limiting mechanism 300 to move, and ensures that the multiple rollers 223 on the support plate 220 are always in contact with the bent sheet metal. The multiple rotating rods 321 always limit the two sides of the sheet metal, thus achieving support and limiting of large-sized sheet metal, preventing the large-sized sheet metal from shifting during bending, and ensuring the quality of the sheet metal after processing.

[0042] like Figure 2 As shown, in this embodiment, a rubber dust cover 230 is bonded and fixed between the carrier shell 210 and the carrier plate 220.

[0043] In practice, a rubber dust cover 230 is used to cover the gap between the bearing shell 210 and the bearing plate 220 to prevent dust and other foreign objects from falling between the bearing shell 210 and the bearing plate 220 and affecting the use of the material support mechanism 200.

[0044] Example 2

[0045] Based on Example 1, in order to improve the limiting effect of large-size plates.

[0046] like Figure 6As shown, in this embodiment, the moving component includes: a fixed housing 330, a connecting seat 360, an electric cylinder 370, and a protective housing 380. The fixed housing 330 is fixedly connected to the connecting housing 310. The connecting seat 360 is disposed inside the fixed housing 330. Two rubber rollers 361 are rotatably connected to the connecting seat 360, and one end of each rubber roller 361 passes through the side wall of the connecting seat 360 and is fitted with a synchronous pulley 362. The electric cylinder 370 is fixedly connected to the fixed housing 330, and the output end of the electric cylinder 370 passes through the fixed housing 310. The protective shell 380 is fixed to one end of the connecting seat 360 and the side wall of the protective shell 380. A stepper motor 381 is fixed inside the protective shell 380, and a connecting rod 382 is fixed to the output end of the stepper motor 381. Two synchronous pulleys 383 are sleeved and fixed on the outside of the connecting rod 382, ​​and the two synchronous pulleys 383 are respectively connected to the outer side of the corresponding synchronous pulley 362 by a synchronous belt 384. Multiple synchronous pulleys 362 are fixed between the top of the connecting seat 360 and the fixed shell 330.

[0047] In practice, the electric cylinder 370 is extended by starting, causing the connecting seat 360 and the rubber roller 361 to move. This allows the rubber roller 361 to contact the top of the board, thus limiting the top of the board and improving the limiting effect. This further prevents the large-sized board from shifting when bending. When the board needs to be unloaded or loaded, the stepper motor 381 is started, which drives the connecting rod 382 to rotate. This causes the two synchronous pulleys 383 to rotate, and the two synchronous belts 384 work in conjunction with the two synchronous pulleys 362 to rotate the two rubber rollers 361. The rotating rubber rollers 361 facilitate the movement of the board by rubbing it, assisting the operator in unloading or loading the board, making it more convenient to use.

[0048] In this invention, to facilitate operator control of the utility model, a PLC controller can be set up, and electric cylinder 240, electric cylinder 250, stepper motor 270, stepper motor 250, electric cylinder 370 and stepper motor 381 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
