Large valve body forming die and vertical four-way forming process thereof

Abstract

The invention discloses a large valve body forming die and a vertical four-way forming process thereof. The large valve body forming die comprises a combined die, an upper die body and a lower die body; an upper die plate is fixedly connected to the outer surface of the upper end of the upper die body; an upper punch is arranged in the middle of the upper die body; an anti-skid protective sleeve is fixedly connected to the lower end of the upper die body; a clamping groove and a positioning clamping groove are arranged in the combined die; a forging valve body is arranged in the positioning clamping groove; a No.1 positioning pressing head is arranged on one side of the middle of the combined die; and a No.2 positioning pressing head is arranged on the other side of the middle of the combined die. According to the large valve body forming die and the vertical four-way forming process thereof provided by the invention, integral forging can be completed at a time, the allowance of each part of a product is uniform, redundant flash materials are not needed, the utilization rate of the materials is increased, the machining period of the product is shortened, the forging qualification rate of the product is increased, the mechanical performance of the product is improved, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of valve body forming, in particular to a large valve body forming mold and a vertical four-way forming process thereof. Background technique [0002] The valve body molding die is a supporting device for valve body molding. The valve body is mainly used on wellhead devices and Christmas tree equipment. It is equipped with an operating gate at a 90° angle to the through hole, which is used to close the valve assembly. When the valve body is made, it needs to be completed with the help of molds. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of valve body forming molds. [0003] There are certain disadvantages in the use of the existing valve body molding dies. First, the product processing is more troublesome, and it cannot be forged well in one line. The long processing cycle of the product has brought some adverse effects on people...

Problems solved by technology

[0003] There are certain disadvantages in the use of the existing valve body molding dies. First, the product processing is more troublesome, and it cannot be forged well in one line. The product processing cycle is long, which brings certain adverse effects to people's use process. Therefore, we propose a large-scale valve body forming mold and its vertical four-way forming process.
