[0026] Example 1

[0027] Reference Figure 1 to Figure 4, which is the first embodiment of the utility model, provides a punching die fixing device, which includes a main body component 100 and a fixing component 200, which can work together to fix the die when punching a metal plate.

[0028] The main assembly 100 includes a punch press 101 , a die plate 102 , a punching plate 103 and an operating table 104 . The die plate 102 is located on the top of the punch press 101 , the punching plate 103 is arranged above the die plate 102 , and the operating table 104 is fixed to one side of the punch press 101 .

[0029] The punch press 101 is a machine tool used for stamping processing. The metal sheet is formed by the die plate 102. The die plate 102 on the punch press 101 is used to support and fix the stamping die. During the stamping process, the stamping die needs to be accurately installed on the die plate 102 to ensure the stability and accuracy of the die during the stamping process. The stamping plate 103 is a tooling used to extrude the metal sheet so as to perform stamping processing on the metal sheet. The operating table 104 is a workbench used to operate the punch press 202 and perform production operations, and is usually used to control the operation of the punch press, safety protection and adjustment of production parameters.

The setting of the moving part 202 can drive the fixing part 201 to move so as to fix different positions of the mold plate 102. The volume of some mold plates 102 is relatively large. By fixing the larger mold plate 102, the fixing part 201 can be moved to the middle of the mold plate 102 so as to stabilize the fixation of the mold plate 102.

[0032] Example 2

[0033] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0034] Specifically, the fixing member 201 includes a push plate 201a, a fixing column 201b and a support bar 201c. The push plate 201a is arranged on one side of the mold plate 102, the fixing column 201b is fixed on one side of the push plate 201a, and the support bar 201c is plugged into one side of the fixing column 201b.

[0035] When the mold plate 102 needs to be fixed, the two push plates 201a are moved toward each other so that the push plates 201a are moved to contact the two sides of the mold plate 102, thereby pushing the two sides of the mold plate 102 to clamp the mold plate 102. The fixed column 201b is used to drive the push plate 201a to move, and the support bar 201c is fixed to the inner wall of the push plate 201a. The setting of the support bar 201c can support the fixed column 201b to prevent the fixed column 201b from shifting during movement.

[0036] Specifically, the fixing member 201 also includes a first threaded rod 201d, a second threaded rod 201e and a handle 201f. The first threaded rod 201d is rotatably connected to one end of the fixing column 201b through a bearing, the second threaded rod 201e is hinged to one end of the first threaded rod 201d, and the handle 201f is inserted into one side of the second threaded rod 201e.

[0037] When the fixed column 201b needs to be moved, the movement of the first threaded rod 201d can drive the fixed column 201b to move. The setting of the second threaded rod 201e can increase the moving length of the fixed column 201b. When the mold plate 102 does not need to be fixed, the second threaded rod 201e can be stored to save space. The setting of the handle 201f is convenient for the user to rotate the second threaded rod 201e. When the second threaded rod 201e rotates, it can drive the first threaded rod 201d to rotate. The rotation of the first threaded rod 201d can cause it to move.

[0038] Specifically, the fixing member 201 further includes a first threaded frame 201g and a second threaded frame 201h. The first threaded frame 201g is arranged at the top of the first threaded rod 201d, and the second threaded frame 201h is arranged at the bottom of the first threaded rod 201d. The first threaded frame 201g and the first threaded rod 201d are threadedly connected.

[0039] The second threaded frame 201h is threadedly connected to the first threaded rod 201d, and the two threaded frames are threadedly connected to the two threaded rods. The two threaded frames can be set so that the threaded rod can move when rotating, thereby driving the push plate 201a to move, so that the mold plate 102 can be clamped.

[0040] Specifically, the fixing member 201 further includes a pressing plate 201i and a fixing plate 201j. The pressing plate 201i is fixed to the top of the first threaded frame 201g, and the fixing plate 201j is fixed to the bottom of the second threaded frame 201h.

[0041] When it is necessary to make the push plate 201a quickly contact with the mold plate 102, the first threaded frame 201g is separated from the top of the first threaded rod 201d by pressing the pressure plate 201i. At this time, the first threaded rod 201d can be quickly moved to make the push plate 201a quickly contact with the mold plate 102, and then the pressure plate 201i is released to make the first threaded frame 201g contact with the threaded rod, and then the threaded rod is rotated, so that the mold plate 102 can be quickly fixed, saving time and improving work efficiency. The fixing plate 201j is used to support the second threaded frame 201h to prevent the second threaded frame 201h from shifting.

[0042] Specifically, the fixing member 201 further includes a positioning plate 201k, a rotating column 201l and a torsion spring 201m. The positioning plate 201k is fixed to the top of the fixing plate 201j, the rotating column 201l is fixed to one side of the pressure plate 201i, and the torsion spring 201m is sleeved on the outside of the rotating column 201l.

[0043] There are two positioning plates 201k, which are fixed on both sides of the first threaded frame 201g respectively. The first threaded frame 201g can be supported by the setting of the positioning plates 201k to prevent the first threaded frame 201g from deflecting. The rotating column 201l is plugged into one side of the positioning plate 201k, and the rotating column 201l is movably connected to the positioning plate 201k. One end of the torsion spring 201m is fixed to one side of the positioning plate 201k, and the other end is fixed to one end of the rotating column 201l. When the pressure plate 201i is moved, the rotating column 201l can be driven to rotate. The rotating column 201l can apply a torsional force to the torsion spring 201m, and the pressure plate 201i moves to drive the first threaded frame 201g to separate from the top of the first threaded rod 201d. At this time, the first threaded rod 201d can be quickly moved to make the push plate 201a quickly contact with the mold plate 102, and then the pressure plate 201i is released. The rotation force of the torsion spring 201m can drive the first threaded frame 201g to contact the threaded rod again, and then the threaded rod is rotated, so that the mold plate 102 can be quickly fixed, saving time and improving work efficiency.

[0044] Specifically, the moving member 202 includes a positioning frame 202a and a slider 202b. The positioning frame 202a is fixed to one side of the punch press 101. A slide groove X is provided on the positioning frame 202a. The slider 202b slides in the slide groove X.

[0045] The slider 202b is fixed to the bottom of the fixed plate 201j. The movement of the slider 202b can drive the fixed plate 201j to move, so that different positions of the mold plate 102 can be fixed. The positioning frame 202a is used to support the slider 202b to prevent the slider 202b from shifting when moving.

[0046] Example 3

[0047] Reference Figure 2 and Figure 3 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0048] Specifically, the moving member 202 further includes a limit block 202c and a moving plate 202d. The limit block 202c is disposed on the top of the positioning frame 202a, and the moving plate 202d is fixed to the top of the limit block 202c.

[0049] The limit block 202c and the movable plate 202d are both arranged on the positioning frame 202a. After the slider 202b is moved to the specified position, in order to prevent the slider 202b from moving by itself, the limit block 202c is brought into contact with the frame of the positioning frame 202a, so that the slider 202b can be limited. The frame of the positioning frame 202a is provided with a friction strip, which can have a large friction force with the limit block 202c. When the limit block 202c is brought into contact with the frame of the positioning frame 202a, a stable limit can be applied to the slider 202b. When it is necessary to release the limit of the slider 202b, the movable plate 202d is squeezed. At this time, the movable plate 202d can drive the limit block 202c to separate from the frame of the positioning frame 202a, thereby releasing the limit of the slider 202b, so that the slider 202b can continue to slide on the slide groove X in the positioning frame 202a.

[0050] Specifically, the moving member 202 further includes a spring 202e and a positioning bar 202f. The spring 202e is fixed to one side of the moving plate 202d. The positioning bar 202f is plugged into one side of the moving plate 202d. The positioning bar 202f and the moving plate 202d are movably connected.

[0051] When the two movable plates 202d are squeezed, the two movable plates 202d move toward each other. The movement of the two movable plates 202d can drive the two limit blocks 202c to move toward each other. At this time, the limit blocks 202c will be separated from the frame of the positioning frame 202a to release the limit on the slider 202b. When the movable plate 202d is squeezed, a squeezing force can be applied to the spring 202e. When the slider 202b needs to be limited again, the movable plate 202d is released. At this time, the rebound force of the spring 202e can drive the limit blocks 202c to contact the frame of the positioning frame 202a, so that the slider 202b can be limited again. The positioning strip 202f is used to support the two movable plates 202d to prevent the movable plates 202d from deviating.

[0052] Specifically, the moving member 202 further includes a connecting plate 202g and a positioning plate 202h. The connecting plate 202g is fixed to one end of the positioning bar 202f, and the positioning plate 202h is sleeved on the outer side of the positioning bar 202f.

[0053] There are two connecting plates 202g, both of which are fixed on the top of the slider 202b. The setting of the connecting plate 202g can support the positioning bar 202f to prevent the positioning bar 202f from shifting. There are two positioning plates 202h, both of which are mounted on the outside of the positioning bar 202f. The setting of the positioning plate 202h can prevent the positioning bar 202f from falling off the connecting plate 202g.

[0054] When in use, when it is necessary to fix the mold plate 102, the mold plate 102 is first placed on the top of the punch press 101. At this time, the push plate 201a needs to be moved to the middle of the mold plate 102 and then clamped. By squeezing the two movable plates 202d, the spring 202e can be applied with a squeezing force when squeezing the two movable plates 202d. The movement of the two movable plates 202d can drive the two limit blocks 202c to move toward each other. At this time, the limit block 202c will be separated from the frame of the positioning frame 202a to release the limit on the slider 202b, and then the slider 202b is moved to make the push plate 201a move to a suitable position, and then the slider 202b is limited, and the movable plate 202d is released. At this time, the rebound force of the spring 202e can drive the limit block 202c to contact the frame of the positioning frame 202a, so that the slider 202b can be limited again.

[0055] After the push plate 201a is moved to a suitable position, the pressure plate 201i is moved. When the pressure plate 201i is moved, the rotating column 201l can be driven to rotate. At this time, the rotating column 201l can apply a torsional force to the torsion spring 201m. The movement of the pressure plate 201i drives the first threaded frame 201g to separate from the top of the first threaded rod 201d. At this time, the first threaded rod 201d can be quickly moved to make the push plate 201a quickly contact with the mold plate 102, and then the pressure plate 201i is released. The force of the rotation of the torsion spring 201m can drive the first threaded frame 201g to contact the threaded rod again, and then the threaded rod is rotated to make the threaded rod drive the fixed column 201b to move. The fixed column 201b can drive the push plate 201a to move by moving, so that the push plate 201a moves to contact one side of the mold plate 102, so that the mold plate 102 can be fixed.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
