Machining stamping device with die convenient to replace

Abstract

The invention discloses a machining stamping device with a die convenient to replace. The machining stamping device comprises a table plate, wherein a plurality of supporting legs are fixedly connected to the bottom of the table plate, a lower mounting block is fixedly connected to the top of the table plate, a mounting groove is formed in the top of the lower mounting block, a lower die is arranged at the top of the lower mounting block, the lower die is matched with the mounting groove, two pressing plates are symmetrically arranged on the two sides of the lower mounting block, two matchingstrips are symmetrically and fixedly connected to the bottoms of the pressing plates, and matching grooves are formed in the outer walls of the matching strips in a penetrating mode. According to themachining stamping device, by arranging first hydraulic cylinders, the pressing plates, the matching grooves, wedge-shaped blocks, pressing blocks and the like, the wedge-shaped blocks are driven by the first hydraulic cylinders to move, the matching strips can be driven to move downwards through mutual matching of the wedge-shaped blocks and the matching grooves, the pressing blocks are driven bythe pressing plates to fix the lower die, the hydraulic cylinders are driven in the direction, and the pressing plates can be jacked up under the action of first springs, so that the lower die is convenient to disassemble.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a stamping device for mechanical processing which is convenient for mold replacement. Background technique [0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. Among the steel products in the world, 60-70% are plates, most of which are stamped into finished products. The body, chassis, fuel tank, radiator fins of the car, the steam drum of the boiler, the shell of the container, the iron core silicon steel sheet of the motor and electrical appliances, etc. are all stamped. There are also a...

Problems solved by technology

Stamping dies are very important in stamping. During the production of small batches of parts, stamping dies need to be replaced frequently. However, most of the dies of existing stamping devices are fixed by a large number of bolts. The installation and disassembly are time-consuming and laborious, and the disassembly efficiency is low.
