DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As mentioned in the background technology, in the prior art, the plate is generally placed on a forming die and then bent by pressing down with an extrusion die. However, due to manual placement, it is difficult to accurately place the plate each time, which causes the extrusion die to cause deviation in the position of the plate. The utility model provides a bending machine for machining mechanical parts. Example

[0024] Reference Figures 1 to 3 , a bending machine for machining mechanical parts, comprising a base 1, a forming die 2 is arranged on the top of the base 1;

[0025] A guide frame 3 is provided on the base 1, and a mounting plate 4 is slidably connected to the guide frame 3. The mounting plate 4 is connected to the piston rod of the cylinder 5, and the cylinder 5 is provided on the guide frame 3. An extrusion die 6 is provided on the mounting plate 4. The sheet is placed on the forming die 2, and the extrusion die 6 is moved downward to extrude the sheet into the forming die 2, and bending can be performed;

[0026] A fixing plate 7 is provided on the right side of the base 1, and a slide rail 8 is provided on the fixing plate 7, and an abutting plate 9 is slidably connected to the slide rail 8, and the bottom of the left end of the abutting plate 9 is in contact with the top of the forming die 2. The abutting plate 9 is guided by the slide rail 8 to move laterally, so that when the plate is placed on the forming die 2, it can move to the right and abut on the abutting plate 9, thereby positioning the placement position of the plate, so as to accurately place the plate, thereby avoiding the extrusion die 6 from causing deviation in the position of the plate extrusion;

[0027] The fixed plate 7 is provided with a moving assembly connected to the abutting plate 9;

[0028] A protection component is provided at the left end of the abutment plate 9 .

[0029] The moving assembly includes a driven shaft 10 connected to the fixed plate 7 through a bearing. The driven shaft 10 is provided with a thread, and the driven shaft 10 is screwed to the abutment plate 9 through the thread. When the driven shaft 10 rotates, the thread drives the abutment plate 9 to move laterally to adjust the position.

[0030] The worker stands on the left side of the base 1 to operate. Since the abutment plate 9 is far away from the worker, in order to adjust the position of the abutment plate 9, a driving shaft 11 located on the front side of the driven shaft 10 is rotatably connected to the fixed plate 7 through a bearing, so that the driving shaft 11 is located on the right hand side of the worker for easy rotation. Pulleys 12 are provided at the right end of the driving shaft 11 and the right end of the driven shaft 10, and belts 13 are connected between the pulleys 12 on both sides. The left end of the driving shaft 11 passes through the base 1 and is connected to a handwheel 14. The worker turns the handwheel 14 with his right hand, so that the driving shaft 11 drives the driven shaft 10 to rotate through the pulleys 12 and the belt 13.

[0031] The protective assembly includes a groove 15 arranged at the left end of the abutment plate 9, an electric telescopic rod 16 is arranged in the groove 15, the electric telescopic rod 16 is powered by the existing technology, a mounting block 17 is arranged at the left end of the electric telescopic rod 16, a protective block 18 is slidably connected to the outer side of the mounting block 17, and a spring 19 connected to the mounting block 17 is arranged on the protective block 18, and the spring 19 is used to cushion the impact received by the protective block 18.

[0032] The outer diameter of the protection block 18 is smaller than the inner diameter of the groove 15 , so that the protection block 18 can be retracted into the groove 15 .

[0033] When the plate is placed directly on the forming die 2 and pushed to the right to contact the abutment plate 9, it is easy to cause damage to the plate and the abutment plate 9 due to the excessive speed. Therefore, the protective block 18 is driven by the electric telescopic rod 16 to extend to the left side of the abutment plate 9, so that when the plate is pushed, the plate can be quickly hit against the protective block 18, and the impact of the plate is buffered by the spring 19 on the protective block 18, thereby avoiding direct impact on the abutment plate 9, and the plate can be quickly approached to the abutment plate 9, and then the protective block 18 is driven by the electric telescopic rod 16 to be retracted into the groove 15, and the plate can continue to be moved to contact the abutment plate 9, so that the plate can be quickly moved to contact the abutment plate 9, and serious damage to the plate and the abutment plate 9 can be avoided. Example

[0034] Reference Figures 1 to 3 A control button 20 electrically connected to the electric telescopic rod 16 is provided on the left side of the base 1, so that workers can control the extension and retraction of the electric telescopic rod 16.

[0035] The rest of the structure is the same as that of Example 1.
