Technical Field

The invention relates to the technical field of chain production, in particular to improved stamping equipment for a conveying chain.

Background

The punching machine, also called as a punch press, has the advantages of material and energy saving, high efficiency, low technical requirement on operators and capability of making products which cannot be achieved by mechanical processing through various die applications compared with the traditional mechanical processing, so that the punching process has wider and wider application. The stamping production mainly aims at plates, blanking, punching, forming, deep drawing, trimming, fine stamping, shaping, riveting, extruding and the like can be performed through a die, and the stamping production is widely applied to various fields, such as switch sockets, cups, cupboards, dishes, computer cases and even missile airplanes … … which have a plurality of accessories can be produced through the die by a punch press.

In the optimization and improvement process of the flat-top chain for conveying, the flattening area of the chain links after being punched is increased, the existing solution method firstly adopts the original mould to produce and then carries out secondary punching operation to flatten the chain links of the flat-top chain, but the method changes the original primary punching into the secondary punching, so that the working efficiency is directly reduced to half of the original efficiency, and the economic benefit of an enterprise is seriously damaged.

Disclosure of Invention

In order to solve the problems in the background art, the invention provides an improved punching device for a conveying chain.

In order to achieve the purpose, the invention provides the following technical scheme:

the improved punching equipment for the conveying chain comprises an improved punching die, a hydraulic mechanism, a punching head and a base, wherein the punching head is arranged above the improved punching die and is installed at the bottom end of the hydraulic mechanism, and the base is arranged below the improved punching die; the highest points of the left side and the right side of the improved punching die are respectively a left top point and a right top point, and the left top point is 0.74-0.76mm lower than the right top point; a groove is formed between the left vertex and the right vertex, the groove is symmetrical left and right, and the left side and the right side of the groove are respectively formed by sequentially tangency of a first fillet, a second fillet, a third fillet and an arc from high to low; the radius of the first round angle is 1.99-2.01 mm; the second fillet radius is 6.14-6.16 mm; the radius of the third fillet is 6.39-6.41 mm; the radius of the circular arc is 410 mm;

mounting plates are fixedly welded on the left side and the right side of the improved punching die, the mounting plates are fixed in positioning holes through fixing bolts, the positioning holes are formed in the upper end face of the sliding seat, the lower end face of the sliding seat is slidably mounted on a sliding groove, and the sliding groove is formed in the upper end face of the base; a detachable connecting piece is fixed on the front end face of the sliding seat through a bolt, an installation upright post is arranged on the left side of the sliding seat, the installation upright post is fixed on the upper end face of the base through a bolt, and the detachable connecting piece is detachably installed on the installation upright post; through the dismantlement of dismantling connecting piece and installation stand like this, can make the improved generation die fix in the punching press position, when needs change the improved generation die, only need lift the dismantled connecting piece off, make sliding seat and installation stand separation, then slide the sliding seat along the spout right side, again with on the sliding seat improved generation die dismantle change can, just so avoided changing the mould under the drift, it is safer.

As a further scheme of the invention: the left vertex is 0.75mm lower than the right vertex.

As a further scheme of the invention: the first fillet radius is 2 mm.

As a further scheme of the invention: the second fillet radius is 6.15 mm.

As a further scheme of the invention: the third fillet radius is 6.4 mm.

Compared with the prior art, the invention has the beneficial effects that:

when using improved generation die to carry out the punching press operation of stock, can once punch and just improve the area that flattens after the chain link punching press, satisfy chain link technology modified demand, the production efficiency of product has been improved greatly, when need not use improved generation die to carry out the punching press operation, still accessible detachable connecting piece and the dismantlement of installation stand, lift detachable connecting piece off, make sliding seat and installation stand separation, then slide the sliding seat along the spout right side, again with the improved generation die on the sliding seat dismantle change can, just so avoided changing the mould under the drift, it is safer. The chain link pressing die is simple in structure principle and low in manufacturing cost, can realize replacement of different dies, can improve the pressing area of the chain link after being pressed by one-time pressing when the improved punching die is used for pressing blanks, meets the requirement of chain link process improvement, and greatly improves the production efficiency of products.
