Adjustable valve plate stamping die

Abstract

The invention discloses an adjustable valve plate stamping die which comprises a stamping loading power base and a base. A hydraulic body is arranged at the middle position of the side, close to the base, of the stamping loading power base. Detachable die seats are movably connected to the symmetrical positions of the inner surface of the side, close to the base, of a limiting die and the inner surface of the top of the base separately. Bayonet balls arranged on shaft rods are movably connected with embedding grooves, the position of the shaft rods can be temporarily fixed through cooperationof the bayonet balls and the embedding grooves, corresponding die tools and die tool matching blocks are installed in a replacement mode according to the type of valve plates needing to be stamped, and the die tools and the die tool matching blocks can be replaced independently so that great convenience is brought during maintenance; and the sides, on the close sides of limiting rods, of movable rods are each movably connected with a limiting clamping base through a reset spring, the valve plates are clamped through grooves of the limiting clamping bases, and therefore the position of the valve plates can be restrained, the situation that the die tools are blocked by the valve plates can be avoided, and under action of the reset springs, valve plates of different sizes can also be tightlyclamped so as not to block the die tools.

Description

technical field [0001] The invention relates to the field of stamping die equipment for valve plates. Background technique [0002] Since there are too many specifications and varieties of the suction and discharge valves of the existing refrigeration compressors, as many as thousands of types, each model needs a pair of stamping dies, and at the same time, each valve of each specification must be designed. Making a set of molds will greatly increase the production cost. If a mold knife is damaged, the whole mold needs to be replaced. It is inconvenient to maintain and wastes time. Moreover, when the mold knife is stamped and reset, the mold knife is easily stuck by the valve plate, and the valve plate The movement of the mold knife brings a lot of troubles to the collection of valve pieces, and improper operation during collection can easily cause the deformation of the valve pieces. Contents of the invention [0003] The main purpose of the present invention is to provi...
