Stamping die capable of finely adjusting die punches

Abstract

The invention discloses a stamping die capable of finely adjusting die punches. The stamping die structurally comprises a base, a lower die block, telescopic arms, a top seat, a lower pressing arm andan upper die block, wherein a fixed block, punches, a fine adjustment device and a limiting device are arranged on the upper die block; the clamping device is formed by a clamping rod, a spring and aclamping plate; the spring is arranged at the side end of the clamping rod; the clamping plate is embedded into the middle of the clamping rod; the spring is movably matched with the clamping rod; and an inclined angle between the clamping plate in a normal state and the horizontal plane is 60 degrees. According to the stamping die, through rotation of a handle in the fine adjustment device, a rotating rod connected to the handle can drive a gear to rotate in more than ten clamping teeth which are transversely arranged; through a sliding fit of the punches and chutes in the fixed block, the punches can be finely adjusted in the fixed block; and when deviation occurs in a use process of the punches, the punches can be finely adjusted by the fine adjustment device without manual disassemblyof the die, so that the thickness and the width of machined parts are finer.

Description

technical field [0001] The invention relates to the field of dies, in particular to a stamping die capable of finely adjusting die punches. Background technique [0002] Stamping die refers to the equipment that uses a punch to stamp metal or non-metallic materials in cold stamping processing. At room temperature, the hydraulic arm is used to push the die to extrude the material, so that the processed parts are deformed to form parts; [0003] Based on the inventor's discovery above, the existing stamping dies that can finely adjust the die punches mainly have the following deficiencies, such as: during the production of parts, the size of the dies changes due to vibrations caused by long-term work, As a result, there is a deviation between the width and thickness of the produced parts and the expected size, especially the difference in the effect produced by the processing of relatively fine parts will be particularly obvious, so it is necessary to disassemble and adjust th...

[0003] Based on the inventor's discovery above, the existing stamping dies that can finely adjust the die punches mainly have the following deficiencies, such as: during the production of parts, the size of the dies changes due to vibrations caused by long-term work, As a result, there is a deviation between the width and thickness of the produced parts and the expected size, especially the difference in the effect produced by the processing of relatively fine parts will be particularly obvious, so it is necessary to disassemble and adjust the die punch, and the disassembly of the die punch is more difficult. Troublesome, so it is necessary to propose a stamping die that can fine-tune the die punch
