Punching die for fittings

Abstract

The invention relates to a punching die for fittings, which comprises a lower die and an upper die in opposite to the lower die; the lower die comprises a bottom plate and an annular placing table arranged at the upper part of the bottom plate and used for placing an object to be processed; a groove is arranged in the middle of the annular placing table, and the upper surface of the annular placing table is provided with a fixing device; the fixing device comprises a first fixing piece for preventing the object to be processed from vertically moving and a second fixing piece for preventing the object to be processed from horizontally moving, the first and the second fixing pieces are linearly distributed; a lower module is arranged in the groove and supported through a compression spring on the bottom plate; two guide pillars are arranged on the lower module, and arranged at both sides of the object to be processed; the upper die comprises a driving component and an upper module; the driving component drives the upper module to vertically move in relative to the lower die; the upper module can be pressed in the groove. The punching die for fittings has the beneficial effects of exactly positioning the work piece, and being long in service life and able to increase the production efficiency.

Description

technical field [0001] The invention relates to the field of auto parts manufacturing, in particular to a stamping die for parts. Background technique [0002] Mold refers to various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] With the rapid development of the national economy, automobiles have become the main means of transportation for people, followed by the vigorous development of the automobile industry. Due to the limitation of the use environment, auto parts need to have high manufacturing precision and assembly precision. Therefore, th...

Problems solved by technology

The defects of this processing method are that the processing efficiency is low, the operation is complicated, the amount of manual labor is large, and experienced workers are required for processing, and the labor cost is high; in addition, the existing molds are not accurate enough for the positioning of the workpiece to be processed. The proportion of processed parts that do not meet the requirements is relatively large; and when the mold is stamped, the force is relatively large, which makes the damage to the machine larger and the life of the machine is shorter
