Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] see figure 2 As shown, it is a structural schematic diagram of the guide die of the present invention. Such as figure 2 As shown, it includes a punch 26, a punch sleeve 21 sleeved at the root of the punch 26, a punch guide sleeve 24 sleeved at the end of the punch 26, wherein the punch sleeve 21 and the punch guide sleeve 24 are arranged There is an elastic member 23 . In this embodiment, the elastic component 23 is a buffer material for the mold, which may be a polyurethane elastomer. In other embodiments, the elastic component 23 can also be other cushioning materials with high elasticity and good flexibility, which should not damage the mold, be durable and easy to use.

[0018] read on figure 2 , which also includes a die 28 provided with a die cavity, and a forging blank 27 to be forged is placed in the die cavity. The side wall of th...

Abstract

The invention provides a guide die, which comprises a punch, a punch sleeve, a punch guide sleeve and an elastic component, wherein the punch sleeve is sheathed at the root part of the punch; the punch guide sleeve is sheathed at the tail end of the punch; the elastic component is located between the punch sleeve and the punch guide sleeve; the elastic component can generate elastic deformation in a pressure direction; after the tail end of the punch guide sleeve is under a contact force, pressure can be applied to the elastic component so as to enable the elastic component to elastically contract; after the contact force at the tail end of the punch guide sleeve is removed, the elastic component is restored to original length; and higher the degree of the elastic contraction of the elastic component is, the longer the dimension of the punch exposed out of the punch guide sleeve. According to the guide die provided by the invention, the punch guide sleeve vertically slides under the action of the elasticity of the elastic component, the punch guide sleeve clings to the punch during a forging process to perform die orifice guide with a female die orifice, and moreover, guide is performed by an outer punch guide sleeve and an outer female die guide sleeve, and therefore, the product precision is improved.

Description

technical field [0001] The invention relates to the field of metal precision forging, in particular to a guide die. Background technique [0002] A mold is a tool used to shape objects. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the processing of the product shape through the change of the physical state of the formed material, so that the product shape conforms to the mold , can complete the molding of complex shape products. [0003] The die for cold forging has the characteristics of high precision and convenient design. The conventional cold forging die can be divided into three major components: upper die, guide structure and lower die. Due to the irregular shape and high precision of some forgings, the ordinary guide structure can no longer meet the production requirements. Therefore, it is necessary to design a guide structure to complete the connection between the upper die (punch) and the lower die (d...
