Description

Technical Field

[0001] The invention relates to the technical field of chain production, in particular to an improved stamping device for conveyor chains. Background Art

[0002] Stamping machine, also known as punch press, has more and more uses than traditional machining because of its advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved through mechanical processing through various mold applications. Stamping production is mainly for sheet metal. Through molds, it can produce blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion parts, etc., which are widely used in various fields, such as the switches and sockets we use, cups, cupboards, plates, computer cases, and even missile aircraft... There are many accessories that can be produced by punching machines through molds.

[0003] In the process of optimizing and improving the flat top chain for conveying, the flattening area of ​​the chain links after stamping was increased. The existing solution is to first use the original mold for production and then perform a secondary stamping operation to flatten the flat top chain links. However, this method changes the original single stamping into two stampings, resulting in a direct reduction in work efficiency to half of the original, seriously damaging the economic benefits of the enterprise. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides an improved punching equipment for conveyor chains.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An improved stamping equipment for conveyor chains, comprising an improved die, a hydraulic mechanism, a punch and a base, wherein a punch is arranged above the improved die, the punch is installed at the bottom end of the hydraulic mechanism, and the base is arranged below the improved die; the highest points on the left and right sides of the improved die are respectively a left vertex and a right vertex, and the left vertex is 0.74-0.76mm lower than the right vertex; a groove is processed between the left vertex and the right vertex, the groove is symmetrical on both sides, and the left and right sides of the groove are respectively composed of a first fillet, a second fillet, a third fillet and an arc, which are tangent in sequence from high to low; the radius of the first fillet is 1.99-2.01mm; the radius of the second fillet is 6.14-6.16mm; the radius of the third fillet is 6.39-6.41mm; the radius of the arc is 410mm;

[0007] The improved die is welded and fixed with mounting plates on the left and right sides, and the mounting plates are fixed in the positioning holes by fixing bolts, and the positioning holes are opened on the upper end face of the sliding seat, and the lower end face of the sliding seat is slidably mounted on the slide groove, and the slide groove is opened on the upper end face of the base; the front end face of the sliding seat is bolted to be fixed with a detachable connecting piece, and a mounting column is provided on the left side of the sliding seat, and the mounting column is bolted to the upper end face of the base, and the detachable connecting piece can be detachably mounted on the mounting column; in this way, the improved die can be fixed in the stamping position by disassembling the detachable connecting piece and the mounting column. When the improved die needs to be replaced, it is only necessary to remove the detachable connecting piece to separate the sliding seat and the mounting column, and then the sliding seat can be slid to the right along the slide groove, and then the improved die on the sliding seat can be disassembled and replaced. This avoids the need to replace the mold under the punch, which is safer.

[0008] As a further solution of the present invention: the left vertex is 0.75 mm lower than the right vertex.

[0009] As a further solution of the present invention: the first fillet radius is 2 mm.

[0010] As a further solution of the present invention: the second fillet radius is 6.15 mm.

[0011] As a further solution of the present invention: the third fillet radius is 6.4 mm.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When the improved punch die is used to perform the punching operation of the blank, the flattening area of ​​the chain link after punching can be increased by one punching, which meets the needs of the chain link process improvement and greatly improves the production efficiency of the product. When the improved punch die is not needed for the punching operation, the detachable connector and the mounting column can be disassembled, the detachable connector can be removed to separate the sliding seat and the mounting column, and then the sliding seat can be slid to the right along the slide groove, and then the improved punch die on the sliding seat can be disassembled and replaced, thus avoiding the replacement of the mold under the punch, which is safer. The present invention has a simple structural principle and low cost, and can realize the replacement of different molds. At the same time, when the improved punch die is used to perform the punching operation of the blank, the flattening area of ​​the chain link after punching can be increased by one punching, which meets the needs of the chain link process improvement and greatly improves the production efficiency of the product.
