[0024] Example 1

[0025] Reference Figure 1 to Figure 4 , which is the first embodiment of the utility model, and this embodiment provides an anti-eccentric load device for a punch cylinder die pad. The anti-eccentric load device for the punch cylinder die pad includes a main component 100 and an auxiliary component 200, and the cooperation of the two can improve the reliability and stability of the equipment.

[0026] The main assembly 100 includes a cylinder 101, a top plate 102, a support plate 103 and a support column 104. The top plate 102 is fixed to the top of the cylinder 101, the support plate 103 is located below the top plate 102, the support column 104 is plugged into one side of the support plate 103, and the support column 104 and the support plate 103 are movably connected.

[0027] The cylinder 101 is usually used to control the offset of the mold. The position of the mold is adjusted by the extension and retraction of the cylinder 101 to ensure the stability and accuracy of the mold during operation. The cylinder 101 can be adjusted as needed to meet the processing requirements of different workpieces. The top plate 102 is the mold pad. The top plate 102 is used to support and fix the important components of the mold. It is usually installed on the upper mold base of the punch press to support the upper mold. The main function of the top plate 102 is to withstand the pressure of the mold and maintain the stability of the mold. At the same time, it can reduce the vibration and noise of the punch press during operation. When the top plate 102 moves, it can drive the support column 104 to move. There are six support columns 104, all of which are located on one side of the support plate 103. The support column 104 moves on the support plate 103 to support the top plate 102 to prevent the top plate 102 from offset.

[0028] The auxiliary component 200 is disposed on the support column 104 , and includes a mounting member 201 and a fixing member 202 . The mounting member 201 is disposed on the support plate 103 , and the fixing member 202 is located on the support column 104 .

[0029] The auxiliary components 200 are divided into six groups, all of which are located on the support plate 103. The support column 104 can be protected by the setting of the mounting member 201, and the support column 104 can be quickly disassembled and assembled by the setting of the fixing member 202. When the support column 104 is damaged, the support column 104 can be quickly replaced, thereby improving the operation efficiency.

[0030] Example 2

[0031] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0032] Specifically, the mounting member 201 includes a protective sleeve 201a and a support ring 201b. The protective sleeve 201a is sleeved on the outside of the support column 104. The protective sleeve 201a and the support column 104 are movably connected. The support ring 201b is fixed to the top of the protective sleeve 201a.

[0033] The protective sleeve 201a is used to protect the support column 104 to prevent the support column 104 and the support plate 103 from being worn. The protective sleeve 201a can be fixed on the support plate 103 by the provision of the support ring 201b.

[0034] Specifically, the mounting member 201 further includes a clamping block 201c and a pressing block 201d. The clamping block 201c is fixed to the bottom of the protective sleeve 201a, and the pressing block 201d is arranged on one side of the clamping block 201c.

[0035] The bottom of the protective cover 201a can be fixed by the setting of the clamping block 201c to prevent the protective cover 201a from falling off the support plate 103 when the support column 104 moves upward. When the protective cover 201a needs to be removed from the support plate 103, the pressing block 201d is pressed, and the pressing block 201d drives the clamping block 201c to move and contract, thereby removing the protective cover 201a from the support plate 103.

[0036] Specifically, the mounting member 201 further includes a spring 201e and a support frame 201f. The spring 201e is plugged into one side of the pressing block 201d. The support frame 201f is sleeved on the outside of the clamping block 201c. The support frame 201f is movably connected to the clamping block 201c.

[0037] When the pressing block 201d is pressed, the pressing block 201d can apply a squeezing force to the spring 201e, and the pressing block 201d drives the clamping block 201c to move and shrink the clamping block 201c, so that the protective cover 201a can be removed from the support plate 103, and then the pressing block 201d is released. At this time, the rebound force of the spring 201e drives the pressing block 201d to return to its original position for the next use. The support frame 201f is fixed to the bottom of the support plate 103. The setting of the support frame 201f can support the pressing block 201d to prevent the pressing block 201d from shifting.

[0038] Specifically, the fixing member 202 includes a fixing block 202a and a moving rod 202b. The fixing block 202a is located at one side of the supporting column 104, and the moving rod 202b is fixed to one side of the fixing block 202a.

[0039] A limiting groove is set on one side of the support column 104, and the fixing block 202a is engaged with the limiting groove. When the support column 104 needs to be fixed to the bottom of the top plate 102, the fixing block 202a is engaged with the limiting groove so that the support column 104 can be fixed to the bottom of the top plate 102. When the support column 104 needs to be quickly removed, the moving rod 202b is moved. The limiting groove is an inclined surface, and the fixing block 202a is an inclined surface. By moving the moving rod 202b with force, the fixing block 202a is separated from the limiting groove, so that the support column 104 can be quickly removed and replaced with a new support column 104.

[0040] Specifically, the fixing member 202 further includes a rotating disk 202c and a pressing plate 202d. The rotating disk 202c is fixed to one side of the moving rod 202b, and the pressing plate 202d is fixed to one side of the rotating disk 202c.

[0041] When the moving rod 202b needs to be moved, the moving rod 202b can be driven to move by the rotation of the rotating disk 202c. The arrangement of the pressing plate 202d facilitates the user to rotate the rotating disk 202c.

[0042] Specifically, the fixing member 202 further includes a fixing plate 202e and a rotating column 202f. The fixing plate 202e is located at one side of the rotating disk 202c. The fixing plate 202e and the rotating disk 202c are movably connected. The rotating column 202f is fixed to one side of the rotating disk 202c.

[0043] The fixed plate 202e is used to support the rotating disk 202c to prevent the rotating disk 202c from deflecting. The rotating column 202f is plugged into one side of the fixed plate 202e. The rotating column 202f is movably connected to the fixed plate 202e and can drive the rotating column 202f to rotate when the rotating disk 202c is rotated.

[0044] Example 3

[0045] Reference Figure 3 and Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0046] Specifically, the fixing member 202 further includes a torsion spring 202g, which is sleeved on the outside of the rotating column 202f, and the torsion spring 202g is also fixed to one side of the fixing plate 202e.

[0047] The torsion spring 202g is fixed to one end of the rotating column 202f. When the rotating column 202f rotates, a torsional force can be applied to the torsion spring 202g. The rotational force of the torsion spring 202g can drive the fixed block 202a to engage with the limiting groove, so that the support column 104 can be limited again to complete the installation of the support column 104.

[0048] During use, when it is necessary to remove the protective cover 201a and replace it with a new one, first raise the support column 104 to the highest position so that the bottom of the support column 104 is separated from the block 201c, and then the pressing block 201d can be pressed. When pressing the pressing block 201d, the pressing block 201d can apply a squeezing force to the spring 201e, and the pressing block 201d drives the block 201c to move and shrink the block 201c, so that the protective cover 201a can be removed from the support plate 103, and then the pressing block 201d is released. At this time, the spring 201e's rebound force drives the pressing block 201d to return to its original position for the next use.

[0049] When the support column 104 needs to be removed, the pressure plate 202d is first pressed. The pressure plate 202d drives the rotating disk 202c to rotate. When the rotating disk 202c is rotated, the rotating column 202f can be driven to rotate. When the rotating column 202f is rotated, a torsional force can be applied to the torsion spring 202g. The rotation of the rotating disk 202c can drive the moving rod 202b to move. By forcibly moving the moving rod 202b, the fixed block 202a is separated from the limiting groove, so that the support column 104 can be quickly removed, and then a new support column 104 can be installed. After the new support column 104 is installed, the pressure plate 202d is released. At this time, the rebound force of the spring 201e drives the pressure block 201d to return to its original position, so that the support column 104 can be limited again.

[0050] 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.
