Compression cracking prevention necking machine for shell head of clamping plate type male joint

Abstract

The invention discloses a compression cracking prevention necking machine for the shell head of a clamping plate type male joint shell. The necking machine structurally comprises a bottom control box,a top supporting plate, a necking box and a necking pressing pipe. The bottom end of the top supporting plate is welded to the upper surface of the bottom control box. When an object is guided in through a necking channel, an ejector head buckle angle can be jacked along the necking top plate, and the end head of the object is enabled to butt an outer sticking layer according to an outward push force; an external force is borne by an inner top arc opening in the outermost side, and the inner top arc opening is clamped between a middle supporting corner and the outer sticking layer, and an outer propping arc can uniformly distribute and slide the force of the outer layer, so that the external force can be better propped against the inside; when the pockets are stressed to swing, the stacked layer is compressed so that the object is clamped in the outer sticking layer in a better way, and the object is subjected to double-layer fixed necking so that the whole object performs extruding against a necking and expanding corner to come out smoothly. When the clamping plate type male joint is subjected to necking compression, the two layers of the clamping plate type male joint can be clamped and fixed and necked at the same time, so that the clamping plate type male joint is prevented from cracking due to stress on the upper layer.

Description

technical field [0001] The invention belongs to the field of necking machines, and more specifically relates to a splint type male shell head anti-compression cracking necking machine. Background technique [0002] The splint type male head is combined and pressed together by the two ends to form a surrounding body. The overall diameter of the inner hole is exactly the same before processing. It needs to be processed by a shrinking machine to make the required part Position apertures vary in size. [0003] Based on the discovery of the above-mentioned inventors, the existing splint-type male housing head necking machine mainly has the following deficiencies, such as: [0004] When the splint type male head is shrinking, when the outer layer of the male head is shrunk under force, the bending force will deform the outer layer and at the same time it will be easier to break the inner layer, resulting in cracking of the splint type male head , the desired shrinkage effect can...

Problems solved by technology

[0004] When the splint type male head is shrinking, when the outer layer of the male head is shrunk under force, the bending force will deform the outer layer and at the same time it will be easier to break the inner layer, resulting in cracking of the splint type male head , the desired shrinkage effect cannot be achieved
