Problems solved by technology

In order to ensure the reliability of hydraulic and pneumatic pipe joints, elbows, tees and fours are usually manufactured by die forging. Blanks are not only low in output but also high in energy consumption, which can neither meet production capacity requirements nor reduce product costs, and more importantly, increase environmental air pollution factors

Embodiment Construction

[0025] refer to Figure 1 to Figure 9 The invention discloses a group die forging manufacturing method for hydraulic and pneumatic pipe joint blanks. The group die forging manufacturing method manufactures pipe joint blanks based on the combined method of one die and multiple pieces, and the head or neck of the pipe joint blanks is absolutely symmetrical. , or cross-face symmetry, the form of each forging in the multi-piece mold is consistent, and the specific form includes: a combination of bends and bends, a combination of three-way and three-way, a combination of four-way and four-way;

[0026] The mold design of the group die forging manufacturing method is designed for the flow direction of the flash: the calculated value of the size of the flash flow LF is: LF=K(H+d1+d2) / 3; when d1=d2, LF=K( H+2d2) / 3; among them, the flash flow LF is the flash flow direction, H is the wrench size of the joint body, d1 is the diameter length of the blank head of the pipe joint, d2 is the ...

Abstract

The invention provides a hydraulic pneumatic pipe joint blank group die forging manufacturing method. The die forging manufacturing method is based on a combined method of one-die multi- forge piecesto make pipe joint blanks. The form of each forge piece is consistent in the combined method of the one-die multi- forge pieces. The specific forms comprise that elbow combines with elbow, three-way combines with three-way and four-way combines with four-way; the die design of group die forging manufacturing method for fly edge flow direction is that the dimension calculation value of the fly edgeflow LF is LF = K (H + D1 + D2) / 3; when D1 = D2, LF = K (H + 2d2) / 3; wherein, the fly edge flow LF is the fly edge flow direction, H refers to the size of a joint body wrench, D1 refers to the head diameter length of a tube joint blank, D2 refers to the neck diameter length of the tube joint blank, and K ranges from 0.8 to 0.9. According to the characteristics that the volume and weight of the hydraulic pneumatic pipe joint blanks are less, the production capacity can be effectively increased, the energy consumption and the production cost can be effectively reduced through the group dieforging manufacturing technology and the combined method of the one-die multi- forge pieces.

Description

【Technical field】 [0001] The invention relates to the technical field of pipe joint production, in particular to a group die forging manufacturing method for hydraulic and pneumatic pipe joint blanks. 【Background technique】 [0002] Hydraulic and pneumatic pipe joints have been widely used in the industrial automation field of modern manufacturing industry, with a large quantity and a wide range. In order to ensure the reliability of hydraulic and pneumatic pipe joints, elbows, tees and fours are usually manufactured by die forging. Blanks are not only low in output but also high in energy consumption, which can neither meet production capacity requirements nor reduce product costs. More importantly, it will increase environmental air pollution factors. A manufacturing method for group die forging of hydraulic and pneumatic pipe joint blanks is proposed. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and pr...
