Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a bending machine for processing mechanical parts. Background Technology

[0002] A bending machine is an industrial device specifically designed for plastically forming metal sheets or profiles. By applying precise pressure and using molds, it bends materials into specific angles, arcs, or complex geometric shapes to meet the manufacturing needs of mechanical parts (such as brackets, housings, connectors, structural components, etc.).

[0003] To address the aforementioned issue of errors in steel extrusion by bending machines, Chinese Patent Publication No. CN222659740U discloses a bending machine for processing mechanical parts. The machine includes a base with a forming mold on its top. A guide frame is mounted on the base, and a mounting plate is slidably connected to the guide frame. The mounting plate is connected to the piston rod of a cylinder, which is mounted on the guide frame. An extrusion mold is mounted on the mounting plate. A fixing plate with a slide rail is located on the right side of the base. A moving assembly moves an abutment plate, allowing the sheet metal placed on the forming mold to move to the right and abut against the abutment plate, thus accurately positioning the sheet metal and preventing deviations caused by the extrusion mold. A handwheel for adjusting the position of the abutment plate is located on the left side of the base for easy worker operation.

[0004] In the above-mentioned solution, when the equipment is used in the field of precision mechanical parts manufacturing, due to the extremely high requirements for the dimensional accuracy, shape accuracy and surface quality of the parts, the bending machine often cannot guarantee the processing accuracy and surface quality due to the possible displacement or bounce of the steel during the processing. This not only affects the quality of product production, but also requires a high level of operator skill. In order to improve the bending accuracy of steel and reduce errors, designing a bending machine for mechanical parts processing has become an urgent problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0006] The present invention adopts the following technical solution: a bending machine for processing mechanical parts, comprising a support frame one, a cylinder and a forming mold fixed on the surface of the support frame one, an extrusion mold fixed on the surface of the cylinder, a clamping device two and a support frame three fixed on both sides of the forming mold, the clamping device two including a motor three, a threaded rod one fixed on the output end of the motor three, a clamping block two threadedly connected to the surface of the threaded rod one, a synchronous wheel one fixed to the surface of the threaded rod one, an abutment plate slidably connected to the surface of the support frame three, and the clamping device one slidably connected to the surface of the abutment plate.

[0007] Preferably, the clamping device includes a slide groove and a motor. A second reversible screw is fixed to the output end of the motor. A second support frame is threadedly connected to the surface of the second reversible screw. The second motor is fixed to the surface of the second support frame. The first reversible screw is fixed to the output end of the motor. A clamping block is threadedly connected to the surface of the first reversible screw. Here, through the cooperation of the various components of the clamping device, materials of different thicknesses requiring bending can be horizontally fixed, avoiding problems such as workpiece misalignment causing inconsistent bending angles.

[0008] Preferably, the surface of the first synchronous pulley is engaged with a synchronous belt, and the inside of the synchronous belt is engaged with a second synchronous pulley. Here, both sets of clamping blocks can be clamped simultaneously, reducing the need for synchronization operations.

[0009] Preferably, a guide rod and a motor four are fixed to the surface of the support frame one, and a threaded rod two is fixed to the output end of the motor four. Here, the motor four can control the sliding of the abutment plate on the support frame three, allowing for the processing of steel materials of different sizes.

[0010] Preferably, there are two sets of both clamping device one and clamping device two, symmetrically distributed on both sides of the abutment plate. This makes the clamping force on the steel more uniform, which is more conducive to processing the steel in a stable environment.

[0011] Preferably, the abutment plate has a telescopic rod one and a telescopic rod two fixed inside, and spring one and spring two are respectively sleeved on the surfaces of telescopic rod one and telescopic rod two. An abutment block is fixed on the surface of telescopic rod one. Here, through the cooperation of spring one and telescopic rod one, the steel can be effectively damped, reducing steel loss.

[0012] Preferably, a buffer pad is fixed to the surface of the abutment block, and the abutment block and the second telescopic rod are rotatably connected by a connecting block. Here, the buffer pad further dampens the steel, thereby reducing the risk of steel displacement caused by vibration.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the steel can be bent by the mutual accessories of the support frame, cylinder, forming mold, extrusion mold and other structures. The horizontal movement of the steel can be restricted by the cooperation of the slide groove, motor, support frame, motor, positive and negative screws and clamping block in clamping device one, so as to reduce the error during processing. The vertical movement of the steel can be restricted by the motor, synchronous wheel, threaded rod and clamping block in clamping device two, so as to fix and limit the steel of different thicknesses and sizes, thus meeting the manufacturing needs of precision mechanical parts with high bending accuracy of steel.

[0015] 2. In this utility model, the combination of buffer pad, abutment block, spring two and telescopic rod two can alleviate the vibration of steel during processing, disperse the force generated by vibration to a certain extent, and further reduce the risk of errors in bending angle caused by displacement of steel.

A clamping device 5 is slidably connected to the surface of the support plate 10. The clamping device 5 includes a slide groove 51 and a motor 52. A positive and negative screw 57 is fixed to the output end of the motor 52. A support frame 53 is threadedly connected to the surface of the positive and negative screw 57. A motor 54 is fixed to the surface of the support frame 53. A positive and negative screw 55 is fixed to the output end of the motor 54.

There are two sets of clamping devices 15 and 26. The two sets of clamping devices 15 and 26 are symmetrically distributed on both sides of the support plate 10, making the clamping force of the steel more uniform and more conducive to the processing of steel in a stable environment.

[0029] Example 2

[0030] Please see Figure 7 The inside of the abutment plate 10 is fixed with telescopic rod 13 and telescopic rod 15. The surfaces of telescopic rod 13 and telescopic rod 15 are respectively fitted with spring 14 and spring 16. The surface of telescopic rod 13 is fixed with abutment block 17.

[0031] Working principle: When using this equipment, the user first needs to adjust the position of the abutment plate 10 on the support frame 12 by starting motor 4 7 according to the actual size of the steel. Then, one end of the steel is brought into contact with the buffer pad 18 and pushed towards the abutment plate 10, so that the steel is horizontal and on the upper surface of the two sets of clamping blocks 64. Next, motor 3 61 is started, which controls the synchronous wheel 9 and synchronous wheel 62 to rotate synchronously, so that the clamping blocks 64 simultaneously tighten the steel, achieving vertical fixation. Then, motor 52 is started, which drives the support frame 53 on the surface of the positive and negative screws 57 to move synchronously. Together with motor 54, it can horizontally fix steel of different sizes and thicknesses, further reducing workpiece displacement and the problem of inaccurate bending angle. At the same time, the cooperation of structures such as telescopic rod 13 and spring 14 can reduce the vibration of the workpiece during processing, further reducing the risk of displacement.
