Stamping lower die with adjustable angle

Abstract

The invention provides a stamping lower die with an adjustable angle and relates to the field of stamping equipment. The stamping lower die comprises a base horizontally arranged and further comprises a central support device, two lower dies which are symmetrical with each other and are in rotating connection with each other, and lifting devices, wherein arc-shaped clamping grooves are symmetrically distributed in the lower sides of the lower dies; the lifting devices are arranged between the base and the lower dies, the lifting devices comprise support parts and lifting rods which are sequentially connected, and the lifting rods are electrically controlled lifting rods; the tops of the support parts are semi-cylindrical, the cross sections of the support parts are semi-circular, the radian of the support parts is larger than that of the arc-shaped clamping grooves, and arc rotating type connection between the support parts and the lower sides of the lower dies is ensured; and the central support device is arranged below the rotating connection part of the two lower dies, the bottom of the central support device is fixed to the base, and a protection plate is further arranged between the central support device and the two lower dies. The problem that the bending degree of the traditional die cannot be adjusted is solved.

Description

technical field [0001] The invention relates to the field of stamping processing, in particular to a lower stamping mold with an adjustable angle. Background technique [0002] In stamping technology, the stamping die is usually divided into an upper die and a lower die. The lower die cannot be adjusted, and the bending angle of the corresponding workpiece cannot be adjusted, which limits the scope of production and processing. When the specifications of the workpiece to be stamped change, the die often needs to be adjusted. It is troublesome to replace the whole set, the cost is also high, and the efficiency is low, which is not conducive to mass production. In the prior art, a utility model patent with the patent number CN201521067632.6 discloses a solution: a stamping lower die, including a base and two lower dies; the base is arranged horizontally; the two lower dies The molds are symmetrically distributed and slidably connected with the base; the lower mold includes a ...

Problems solved by technology

[0003] Although the above solution solves the problem that the bending angle can be adjusted by the processing company, but every time it is used, it is necessary to manually replace the support block and adjust the distance between the two mold seats. Looseness occurs between the seat and the support block, which affects the machining accuracy of the mold
