Pipe fitting notching die

Abstract

The invention discloses a pipe fitting notching die. The pipe fitting notching die comprises an upper die plate and a lower die plate; the lower die plate is provided with a sliding block seat; a sliding block is arranged in the sliding block seat; a spring is arranged between each end surface formed along the length direction of the sliding block and the inner lateral side of the sliding block seat; a cylindrical groove with two open ends is hollowed out along the width direction of the sliding block; a core rod is arranged in the cylindrical groove in an interference fit mode; one side of the sliding block seat is provided with a pipe fitting through hole and the other side of the sliding block seat is provided with a sliding groove; a guide mechanism is arranged in the sliding groove; the guide mechanism is fixedly connected with the sliding block; the inner side of the upper die plate is provided with a backing plate; an inclined wedge is fixedly arranged on the backing plate; the inclined wedge is formed by a first inclined wedge and a second inclined wedge; the inner side inclined surfaces of the first inclined wedge and the second inclined wedge are matched with the two end surfaces formed in the length direction of the sliding block respectively. According to the pipe fitting notching die, the structure is simple, the operation is convenient, two notches can be stamped and cut out at one time, and accordingly the stamping times are reduced under the condition that the concentricity of the two notches is ensured, the stamping cost is low, the product quality is high, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of cold stamping dies for notches of pipe fittings, in particular to a notching die for pipe fittings capable of cutting two notches at one time. Background technique [0002] Mold is a tool product with a large amount of use and a wide range of influence in the manufacturing industry. In modern mass production, without high-level molds, there will be no high-quality products. [0003] With the reform and opening up and the rapid development of the national economy, the new development of mold technology and mold industry has been promoted. The variety development of modern industrial products and the improvement of production efficiency depend to a large extent on the development of molds and the technical and economic level. Industry has become an important part of the high-tech industry. Modern molds are process-intensive industries under the background of high technology. The level of mold technology largely dete...

Problems solved by technology

[0004] In the existing technology, two stampings are generally used in the domestic pipe fittings cutting process. Since the positioning of the two stampings cannot be completely the same, the two stampings cannot be concentric, and the processing accuracy is low, which in turn affects Subsequent welding and other assembly effects of pipe fittings seriously affect the efficiency of production and product quality. Low, the pipe fitting notch mold that obtains high product quality is a technical problem to be solved urgently by those skilled in the art
