Embodiment Construction

[0026] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0027] Such as figure 1 and 2 As shown: the present invention provides a necking mold device for workpiece processing, and the necking mold device for workpiece processing includes a base 1, and a first mold 5 and a second mold are respectively slidably arranged on the base 1 7. After the first mold 5 and the second mold 7 are docked, a processing hole with a large outside and a small inside is formed at the end, and the base 1 is also fixed with the first mold 5 and the second mold. The positioning plate 8 between the second mold 7, the positioning pin 9 is fixed on the positioning plate 8, the support 3 is also fixed on the first mold 5, the first cylinder 2...

Abstract

The invention discloses a necking die device for workpiece machining. The necking die device for workpiece machining comprises a base, a first die and a second die are slidably arranged on the base respectively, after the first die and the second die are in butt joint, a positioning plate located between the first die and the second die is further fixed to the base, a positioning pin is fixed to the positioning plate, a support is further fixed to the first die, a first air cylinder is further fixed to the base, a piston rod of the first air cylinder is connected with the support, and a conveying frame is fixed to the base; and at least a part of a pipe fitting is clamped on a conveying frame, so that the end part of the pipe fitting is positioned between the first die and the second die.The problems that in the operation process of an existing necking die, a port of the pipe fitting is likely to be broken, and meanwhile the forming precision of the die is low are solved.

Description

technical field [0001] The invention relates to mechanical processing, in particular to a necking die device for workpiece processing. Background technique [0002] The plastic processing of pipe fittings is a basic metal processing technology that makes the pipe plastically deformed under the action of external force to obtain the desired shape, size, structure and performance of the product. It mainly includes bending, bulging, flaring, shrinking , Flipping, etc. Among them, necking is a molding process in which the mouth of the pipe fitting is reduced through a necking die. The existing necking mold is easy to cause the rupture of the port of the pipe fitting during operation, and at the same time, the forming precision of the mold is low. Contents of the invention [0003] The object of the present invention is to provide a necking mold device for workpiece processing, which solves the problems that the existing necking mold is easy to cause the rupture of the pipe p...
