Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to an adjusting mechanism. Background Art

[0002] In a drawing die, the gap at each position between the blank holder and the die directly affects the shrinkage state of the sheet metal, the drawing quality, and the service life of the drawing die; this gap is adjusted by adjusting the height of the pads at each position of the blank holder, and the optimal state of sheet metal drawing is achieved through the adjustment of the height of the pads.

[0003] The adjusting mechanisms in the prior art generally adjust the gap between the blank holder and the die by adding shims under the pads. The adjustment process requires workers to open the die, remove the pads, and add shims of different thicknesses. The operation process is complex and cumbersome, and has high requirements for the skills of the adjusters. In addition, the shim material is soft, resulting in a low overall bearing capacity of the main block. After long-term stamping deformation, the height of the pads will change, thus affecting the adjustment accuracy of the main block.

[0004] Therefore, the prior art has the disadvantages of cumbersome drawing gap adjustment process, low adjustment accuracy, high requirements for the skills of adjusters, and low efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an adjusting mechanism, which can solve the technical problems of cumbersome adjustment process, low adjustment accuracy, high requirements for the skills of adjusters, and low efficiency of the existing adjusting mechanism.

[0006] To achieve the above purpose, an adjusting mechanism designed by the utility model includes an upper shell, a main block, a slider, and an adjusting screw. The main block and the slider are sequentially arranged below the upper shell. The upper shell is provided with an installation hole in the vertical direction. The main block passes through the installation hole and extends upward out of the upper shell. The adjusting screw is arranged on the side of the upper shell, and the tail of the adjusting screw abuts against the slider.

[0007] As a preferred scheme, the bottom of the upper shell is provided with an installation groove communicated with the installation hole, and the main block and the slider are arranged in the installation groove.

[0008] Further, the head of the adjusting screw is provided with a scale, and the adjusting screw is rotatably connected to the side of the upper shell.

[0009] As a preferred scheme, a corrugated spring for retraction is arranged on the main block.

[0010] As a preferred scheme, a return spring for retraction is arranged on the slider.

[0011] As a preferred solution, the manual adjustment mechanism further includes a fixing block, which is arranged between the upper housing and the adjustment screw. The adjustment screw passes through the threaded hole of the fixing block and abuts against the side groove on the side of the slider.

[0012] As a preferred solution, the manual adjustment mechanism further includes a base, which is arranged at the bottom of the slider.

[0013] As a preferred solution, the manual adjustment mechanism further includes a motor drive assembly, which is arranged at the lower end of the base. The drive block of the motor drive assembly extends upward out of the base and abuts against the slider.

[0014] Further, the electric control drive assembly includes a drive block, a motor, and a lead screw assembly connecting the drive block and the motor. The motor is arranged at the lower end of the base. The drive block is arranged in the guide hole of the base. The drive block is located below the adjustment screw and extends upward out of the base to abut against the side of the slider.

[0015] Further, the abutting surface between the drive block and the slider is a mutually matching inclined surface, and the direction of the inclined surface is inclined downward along the extending direction of the slider.

[0016] Advantages of the present utility model:

[0017] The adjustment mechanism of the present utility model abuts against the slider through the tail of the adjustment screw. When the adjustment screw rotates, the slider drives the main body block to move up and down in the upper housing, so as to achieve the purpose of adjusting the height of the main body block. During the die debugging stage, manual adjustment is carried out through the adjustment screw, without the need to debug on a stamping device with an adjustment control system, which solves the limitation of the debugging device and reduces the debugging cost at the same time. During the formal production stage, an electric adjustment is carried out by using the motor drive assembly to improve production efficiency.

[0018] Therefore, the present utility model can solve the technical problems of the existing adjustment mechanism, such as cumbersome adjustment process, low adjustment accuracy, high skill requirements for adjusters, and low efficiency. Description of the drawings
