Production method of valve workpiece

Abstract

The invention discloses a production method of a valve workpiece. The production method comprises the following steps that (1), casting forming is conducted; (2), a charges handle is removed, specifically, the charges handle of a workpiece blank in the step (1) is subjected to workpiece cutting for burr removal through cutting equipment; (3), the workpiece is cleared; (4), tapping is conducted, specifically, the workpiece is subjected to automatic tapping operation through automatic tapping equipment, and outer threads are machined on two connecting columns of the workpiece are machined; (5),shot blasting is conducted, specifically, surface shot blasting treatment is conducted on the deburred workpiece through a shot blasting machine; and (6), acceptance check is conducted. According to the production method of the valve workpiece, full-automatic operation of valve body production is achieved, the work efficiency is high, the production speed of a valve body is high, and the supply and demand proportion is met; the qualification rate of an external thread of the workpiece is high, the condition of a defective product or a scrapped product is basically avoided, re-work of the product is reduced, and the production efficiency is improved to a great extent; and through a multi-step technique of burr removal, high-pressure air spraying for clearing, shot blasting and the like, theworkpiece is treated, and thus the overall aesthetic degree of the workpiece is high.

Description

technical field [0001] The invention belongs to the technical field of parts processing, and in particular relates to a production method of valve workpieces. Background technique [0002] Natural gas control valves, such as gas valves, etc., need to tap the left and right connecting columns of the valve body to form external threads. However, the existing external thread processing of the valve body is all manual operation. Workers use dies to manually tap the valve body. Not only is the efficiency low, but also the thread uniformity of the tapping is poor, which affects the quality of the product. Due to this limitation, it is impossible to use automated equipment to form a coherent production line during the production of the valve body. The manufacturing efficiency of the valve body is low, and it is difficult to meet the market demand. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a production method...

Problems solved by technology

However, the existing external thread processing of the valve body is all manual operation. Workers use dies to manually tap the valve body. Not only is the efficiency low, but the thread uniformity is poor, which affects the quality of the product.

Due to this restriction, the valve body cannot be produced using automated equipment to form a coherent production line, and the manufacturing efficiency of the valve body is low, making it difficult to meet market demand.
