[0002] Bending machines mainly refer to sheet metal bending machines, which are used to perform bending and forming operations on various plastic and metal sheets. They are mainly used in the sheet metal industry. Bending machines can be classified into different types according to different characteristics. Common bending machines include manual bending machines, numerical control bending machines, hydraulic bending machines, etc.

This technology discloses "including a bending machine body, a first T-shaped groove, and an adjusting block; a first T-shaped groove is provided at the front end of the bending machine body, and the bending machine body and the first T-shaped groove are of an integral structure; the adjusting block is arranged on the upper part of the first T-shaped groove, and the adjusting block is slidably connected to the first T-shaped groove in a clearance fit manner; the second T-shaped groove is located in the middle position of the upper part of the adjusting block, and the second T-shaped groove and the adjusting block are of an integral structure; the working panel is arranged at the front end of the adjusting block, and the working panel is fixedly connected to the adjusting block by bolts, etc. technical solutions. This application has the technical effects of accurate positioning of the workpiece feeding size, greatly improving the bending quality, high adjustment flexibility, and greatly improving its practical performance and practical value";

[0004] Regarding the above related technologies, the inventor believes that most bending machines cannot achieve an accurate positioning effect on the bending target while performing bending operations, and manual positioning is required. The bending target is prone to deviation, resulting in deviations in the bending position and bending angle. It is difficult to achieve accurate and unified positioning accuracy, which leads to the bending structure not meeting the bending standards, reducing the efficiency of the bending work and increasing the difficulty of the bending operation. Summary of the Utility Model

[0005] The purpose of this application is to provide a bending machine that improves the positioning effect to improve the problems of inaccurate positioning and unstable bending target.

[0006] The bending machine provided in this application for improving the positioning effect adopts the following technical solutions:

[0007] A bending machine for improving the positioning effect, including a machine body. A bending groove is provided on the outer surface of one end of the machine body. Two vertical plates are fixedly connected to the inner walls on both sides of the top of the machine body. Chute grooves are provided at one ends of the opposite surfaces of the two vertical plates. A first fixing plate is slidably connected between the two chute grooves. A pressing plate is fixedly connected to the bottom end of the first fixing plate. A pressing head is fixedly provided at the bottom end of the pressing plate. A fixing device is fixedly installed at the end of the machine body where the bending groove is provided. A positioning device is fixedly installed on the outer surface of one end of the machine body. The positioning device includes a bottom plate. A cylinder is fixedly connected to the bottom end of the bottom plate. And the output end of the cylinder penetrates through the bottom plate and is fixedly connected to a fixing block. Two fixing bolts are fixedly provided on the outer surface of one end of the bottom plate. Two support plates are fixedly provided on the upper part of one end of the bottom plate. A movable plate is rotatably provided between the two support plates. A first rotating shaft is inserted between the movable plate and the two support plates. A pushing plate is fixedly provided at one end of the movable plate. A roller is rotatably connected to the inner wall of the other end of the movable plate. Second rotating shafts are inserted through the outer surfaces of both ends of the movable plate. The second rotating shafts penetrate through the roller.

[0008] By adopting the above technical solution, start the cylinder. The cylinder pushes the fixing block to move upward, causing the roller connected to the movable plate to rotate and fit the inclined surface of the fixing block, so that the pushing plate connected to the movable plate moves horizontally towards the bending target through the first rotating shaft, thereby pushing the bending target to the bending point to achieve the positioning purpose.

[0009] Optionally, the fixing device includes a support frame. A first motor is fixedly installed at one end of the support frame. The output end of the first motor penetrates through the support frame and is fixedly connected to a bidirectional threaded rod. Clamping plates are sleeved on the parts of the outer surface of the bidirectional threaded rod with different thread directions. A limit block is fixedly provided at the end of the bidirectional threaded rod away from the first motor.

[0010] By adopting the above technical solution, start the first motor to drive the bidirectional threaded rod to rotate, thereby driving the two clamping plates to perform an opposite clamping movement along the threads of the bidirectional threaded rod to achieve the purpose of stably bending the target. The limit block prevents the clamping plates from rushing out of the bidirectional threaded rod.

[0011] Optionally, a rolling groove is provided on the outer surface of one end of the first fixing plate. A bearing is rotatably connected to the inner wall of the rolling groove. A connecting plate is fixedly connected to one end of the bearing. A rotating disk is fixedly connected to the bottom end of the connecting plate. A second fixing plate is fixedly connected to the upper part of one end of the machine body. A second motor is fixedly connected to one end of the second fixing plate. And the output end of the second motor penetrates through the second fixing plate and is fixedly connected to the rotating disk.

[0012] By adopting the above technical solution, the output end of the second motor drives the rotating disc to rotate, thereby driving the connecting plate connected to the rotating disc to rotate, and then driving the bearing to rotate along the rolling groove. The bearing exerts a horizontal force on the first fixing plate. Since the first fixing plate can only slide up and down through the sliding groove, the horizontal force is converted into a vertical up and down force, resulting in the first fixing plate sliding up and down along the sliding groove. The pressing head connected to the pressing plate at the bottom end of the first fixing plate exerts a vertical force on the bending target downward. The pressing head bends the bending target through the bending groove, achieving repeated up and down bending operations.

[0013] Optionally, both the pressing head and the bending groove are in a "V" shape.

[0014] By adopting the above technical solution, the pressing head can be squeezed and fitted along the bending groove, facilitating the bending operation on the bending target.

[0015] Optionally, one outer surface of the fixed block is inclined, and the width of the movable plate is the same as that of the fixed block. The fixed block is used in cooperation with the roller.

[0016] By adopting the above technical solution, the outer surface of the roller is mutually attached to the inclined surface of the fixed block, facilitating the extension of the movable plate by the up and down movement of the fixed block.

[0017] Optionally, both the machine body and the two clamping plates are in an "L" shape, and the two clamping plates are mirror-symmetrically distributed.

[0018] By adopting the above technical solution, it is convenient for the two clamping plates to perform a stable clamping operation on the clamped target with relative movement.

[0019] Optionally, the length of the bidirectional threaded rod is the same as the length of the bending groove.

[0020] By adopting the above technical solution, the maximum clamping distance is not allowed to exceed the length of the bending groove.

[0021] Optionally, the two vertical plates are mirror-symmetrically distributed.

[0022] By adopting the above technical solution, the two sliding grooves of the two vertical plates slide horizontally and fit the fixing plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the positioning device in the present utility model, the bending target is pushed towards one side of the machine body by the lateral force generated by the cooperation of the pushing plate and the cylinder, so that the bending point of the bending target is accurately positioned at the bending groove, thereby realizing the accurate positioning of the bending target and achieving the effect of improving the positioning accuracy.

[0025] 2. The utility model realizes the operation of firmly clamping the bending target while positioning the bending target by setting a fixing device, so that the bending target is not easily offset or deformed during bending, achieving the effect of stably clamping the bending target. And by setting a chute and a rolling groove, the two interact to achieve the effect of automatically pressing and bending repeatedly. BRIEF DESCRIPTION OF THE DRAWINGS

A pressing plate 14 is fixedly connected to the bottom end of the first fixing plate 13. A pressing head 141 is fixedly provided at the bottom end of the pressing plate 14. A fixing device 2 is fixedly installed at the end of the body 1 where the bending groove 12 is opened. A positioning device 3 is fixedly installed on the outer surface of one end of the body 1. The positioning device 3 includes a bottom plate 32. A cylinder 31 is fixedly connected to the bottom end of the bottom plate 32. And the output end of the cylinder 31 penetrates through the bottom plate 32 and is fixedly connected to a fixing block 37. Two fixing bolts 30 are fixedly provided on the outer surface of one end of the bottom plate 32. Two support plates 34 are fixedly provided on the upper part of one end of the bottom plate 32. A movable plate 35 is rotatably arranged between the two support plates 34. A first rotating shaft 341 is inserted between the movable plate 35 and the two support plates 34. A pushing plate 351 is fixedly provided at one end of the movable plate 35. A roller 36 is rotatably connected to the inner wall of the other end of the movable plate 35. Second rotating shafts 350 are inserted through the outer surfaces of both ends of the movable plate 35. The second rotating shafts 350 penetrate through the roller 36. When the cylinder 31 is started, the cylinder 31 pushes the fixing block 37 to move upward, causing the roller 36 connected to the movable plate 35 to rotate and fit the inclined surface of the fixing block 37, so that the pushing plate 351 connected to the movable plate 35 moves horizontally towards the bending target through the first rotating shaft 341, thereby pushing the bending target to move to the bending point to achieve the positioning purpose.

[0033] Refer to Figure 1 , both the pressing head 141 and the bending groove 12 are in a "V" shape.

[0034] Refer to Figure 3 , one outer surface of one end of the fixing block 37 is inclined, and the width of the movable plate 35 is the same as the width of the fixing block 37. The fixing block 37 and the roller 36 are used in cooperation.

[0035] Refer to Figure 1 , both the body 1 and the clamping plates 23 are in an "L" shape, and the two clamping plates 23 are mirror-symmetrically distributed.

[0036] Refer to Figure 1 , the length of the bidirectional threaded rod 24 is the same as the length of the bending groove 12.

[0037] Refer to Figure 1 , the two vertical plates 11 are mirror-symmetrically distributed.

[0038] The implementation principle of the embodiment of this application is: When the cylinder 31 is started, the cylinder 31 pushes the fixing block 37 to move upward, causing the roller 36 connected to the movable plate 35 to rotate and fit the inclined surface of the fixing block 37, so that the pushing plate 351 connected to the movable plate 35 moves horizontally towards the bending target through the first rotating shaft 341, thereby pushing the bending target to move to the bending point to achieve the positioning purpose.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 lies in that:

[0041] Referring to Figure 1 , the fixing device 2 includes a support frame 21. A first motor 22 is fixedly installed at one end of the support frame 21. The output end of the first motor 22 penetrates through the support frame 21 and is fixedly connected to a bidirectional threaded rod 24. Clamping plates 23 are sleeved on different threaded portions of the outer surface of the bidirectional threaded rod 24. A limiting block 25 is fixedly arranged at the end of the bidirectional threaded rod 24 away from the first motor 22. Starting the first motor 22 drives the bidirectional threaded rod 24 to rotate, thereby driving the two clamping plates 23 to move in opposite directions along the threads of the bidirectional threaded rod 24 to achieve the purpose of stable bending. The limiting block 25 prevents the clamping plates 23 from rushing out of the bidirectional threaded rod 24.

[0042] Referring to Figure 3 , a rolling groove 131 is formed on the outer surface of one end of the first fixing plate 13. A bearing 41 is rotatably connected to the inner wall of the rolling groove 131. One end of the bearing 41 is fixedly connected to a connecting plate 42. The bottom end of the connecting plate 42 is fixedly connected to a rotating disk 43. The upper part of one end of the machine body 1 is fixedly connected to a second fixing plate 44. One end of the second fixing plate 44 is fixedly connected to a second motor 45. The output end of the second motor 45 penetrates through the second fixing plate 44 and is fixedly connected to the rotating disk 43. When the second motor 45 is started, the output end of the second motor 45 drives the rotating disk 43 to rotate, thereby driving the connecting plate 42 connected to the rotating disk 43 to rotate, and then driving the bearing 41 to rotate along the rolling groove 131. The bearing 41 exerts a horizontal force on the first fixing plate 13. Since the first fixing plate 13 can only slide up and down through the sliding groove 111, the horizontal force is converted into a vertical up-and-down force, resulting in the first fixing plate 13 sliding up and down along the sliding groove 111. A vertical force is applied downward to the bending target through the pressing head 141 connected to the pressing plate 14 at the bottom end of the first fixing plate 13. The pressing head 141 bends the bending target through the bending groove 12 to achieve repeated up-and-down bending operations.

The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
