Novel guiding column and guiding sleeve

Abstract

The invention discloses a novel guiding column and guiding sleeve which comprises a guiding column body and a guiding sleeve body in matched connection with the guiding column body. The guiding column body comprises a cylinder and an external cone arranged on the right side of the cylinder; and a first standard metric internal thread is arranged in the cylinder, an external conical face is arranged on the outer wall of the external cone, and a first screw locating position is arranged in the external cone. A concave cavity is formed in the guiding sleeve body, an internal conical face is arranged on the inner wall of the concave cavity, and a second standard metric internal thread is arranged on the right side of the concave cavity; and a second screw locking position is arranged in the concave cavity, the incremental ratio between the increment and the length of the diameter of the conical face of the external cone is 1:10 to 1:50, and the clearance between the external conical face and the internal conical face is 0.002mm. The guiding column and guiding sleeve is more convenient to install, disassemble and replace, automatic centering is achieved in an installing process of the guiding column and guiding sleeve, the guiding column and guiding sleeve does not need to be adjusted in use, and the combining concentricity is smaller than 0.006mm. The guiding column and guiding sleeve is high in combining accuracy, more excellent in interchangeability, simple to manufacture and convenient to use. In addition, the producing cost is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of mold accessories, in particular to a novel guide post and guide sleeve. Background technique [0002] At present, a mold is a tool used to shape an article, and it mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. The guide post is one of the important components of the mold guide parts, and the other component is the guide sleeve, which is used to ensure that the punch and die can accurately realize the design parameters during work. In order to improve the guiding accuracy and the life of the parts, the friction gap between the guide post and the guide sleeve should be small. The precision of the guide directly affects the forming quality of the workpiece. The currently used guide posts and guide sleeves are mainly driven into the preset through holes on the template by beating the guide posts and guide sleeves with copper rods....

AI Technical Summary

Problems solved by technology

The currently used guide posts and guide sleeves are mainly punched into the preset through holes on the template through copper rods. This processing method has the following disadvantages: 1. Although softer Copper rods are used to beat, but it will still cause some damage to the guide post and guide sleeve

2. The installation is difficult, and the installation is prone to deflection. Once an installation error occurs, it will cause damage to the formwork on the one hand, and damage to the guide post and guide sleeve on the other hand; when the holes on the formwork are blind holes , Disassembly may use special processing equipment such as electric sparks to destructively disassemble the guide post or guide sleeve
