[0028] Example 2
[0029] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.
[0030] Specifically, the driving member 104 includes a moving block 104a and a moving rod 104b. The moving block 104a is fixed to the top of the stamping plate 102, and the moving rod 104b is hinged to the top of the moving block 104a.
[0031] When the workpiece needs to be punched, the stamping plate 102 is moved by the movement of the moving block 104a. At this time, the workpiece can be punched by the movement of the stamping plate 102, and the moving rod 104b can drive the moving block 104a to move.
[0032] Specifically, the driving member 104 further includes a moving sleeve 104c and a rotating block 104d. The moving sleeve 104c is sleeved on the outside of the moving rod 104b. The moving sleeve 104c and the moving rod 104b are threadedly connected. The rotating block 104d is hinged to one side of the moving sleeve 104c.
[0033] The movement of the movable sleeve 104c can drive the movement of the movable rod 104b. When it is necessary to stamp workpieces of different heights, the movable sleeve 104c can be extended and retracted by rotating the movable rod 104b. The height of the stamping plate 102 can be adjusted by moving the movable rod 104b, so that workpieces of different heights can be stamped. The rotation of the movable rod 104b belongs to the prior art, so it will not be elaborated in detail. The rotation of the rotating block 104d can drive the movement of the movable sleeve 104c. The rotation of the rotating block 104d belongs to the prior art, so it will not be elaborated in detail.
[0034] Specifically, the punching member 201 includes a punching rod 201a and a spring 201b. A slide groove X is provided on the stamping plate 102. The punching rod 201a slides in the slide groove X. The spring 201b is located at the top of the punching rod 201a.
[0035] When the workpiece on the stamping plate 102 needs to be separated from the stamping plate 102, the workpiece can be removed from the stamping plate 102 by squeezing the top of the workpiece with the punching rod 201a. When the punching rod 201a squeezes the top of the workpiece, the spring 201b can apply a squeezing force. After the workpiece is removed, the rebound force of the spring 201b can drive the punching rod 201a to be separated from the stamping plate 102 for next use.
[0036] Specifically, the punching piece 201 also includes a first fixed block 201c, a second fixed block 201d and a support bar 201e. The first fixed block 201c is fixed to the top of the punching rod 201a, the second fixed block 201d is fixed to the top of the spring 201b, and the support bar 201e is fixed to one end of the second fixed block 201d.
[0037] The first fixed block 201c is fixed to the bottom of the spring 201b. The first fixed block 201c and the second fixed block 201d are arranged to support the spring 201b to prevent the spring 201b from being offset. The support bar 201e is fixed to one side of the stamping plate 102. The second fixed block 201d is supported by the arrangement of the support bar 201e to prevent the second fixed block 201d from being offset.
[0038] Specifically, the fixing member 202 includes a fixing rod 202a and a positioning block 202b. The positioning block 202b is fixed to one side of the punch press 101, and the fixing rod 202a is fixed to the bottom of the positioning block 202b.
[0039] When it is necessary to make the punching rod 201a squeeze the top of the workpiece, the stamping plate 102 is moved upward, and the stamping plate 102 moves to drive the punching rod 201a to move. When the punching rod 201a is moved to contact the bottom of the fixed rod 202a, the top of the punching rod 201a will be squeezed to make it move. When the punching rod 201a moves, the spring 201b can apply an squeezing force, and the punching rod 201a moves to contact the top of the workpiece and squeezes the top of the workpiece, so that the workpiece can be removed from the stamping plate 102. Then the stamping plate 102 is returned to its original position, and the punching rod 201a is moved to separate from the bottom of the fixed rod 202a. The rebound force of the spring 201b drives the punching rod 201a to return to its original position for the next use. The positioning block 202b is used to support the fixed rod 202a to prevent the fixed rod 202a from deviating.
[0040] During use, when it is necessary to stamp a workpiece, first fix the workpiece at the bottom of the stamping plate 102, then start the rotating block 104d to rotate the rotating block 104d, and the rotation of the rotating block 104d can drive the movable sleeve 104c to move, and the movement of the movable sleeve 104c drives the movable rod 104b to move, and the movement of the movable rod 104b can drive the movable block 104a to move, and the movement of the movable block 104a drives the stamping plate 102 to move. At this time, the stamping plate 102 moves to contact with the base 103, and the workpiece can be stamped.
[0041] After the punching of the workpiece is completed, the workpiece needs to be removed from the punching plate 102. The punching plate 102 is moved to separate from the base 103 and the punching plate 102 is moved upward. The movement of the punching plate 102 drives the punching rod 201a to move. When the punching rod 201a is moved to contact the bottom of the fixed rod 202a, the top of the punching rod 201a is squeezed to make it move. When the punching rod 201a moves, an squeezing force can be applied to the spring 201b. The punching rod 201a moves to contact the top of the workpiece and squeezes the top of the workpiece, so that the workpiece can be removed from the punching plate 102. Then the punching plate 102 is returned to its original position, and the punching rod 201a is moved to separate from the bottom of the fixed rod 202a. The rebound force of the spring 201b drives the punching rod 201a to return to its original position for next use.
