Tungsten steel push rod and its processing method

Abstract

The invention discloses a tungsten steel push rod. The tungsten steel push rod comprises a cylindrical push rod body, wherein the push rod body comprises a first push rod part, a second push rod part and a third push rod part which are arranged coaxially from left to right; a groove is annularly formed around the axis of the push rod body outside the first push rod part; four first planes are uniformly distributed on the periphery of the second push rod part in an annular form; four second planes are uniformly distributed on the periphery of the third push rod part in an annular form; a first threaded hole is formed in the center, far away from the second push rod part, of the third push rod part, and extends into the first push rod part from the third push rod part, but does not penetrate through the first push rod part; a second threaded hole is formed in one of second arc surfaces along the axial direction which is perpendicular to the push rod body, and extends into the first threaded hole. The invention also discloses a machining method for the tungsten steel push rod. By the machining method, the size precision of the tungsten steel push rod is accurate, the production process is qualified at one time, and product obsolescence rate is low.

Description

technical field [0001] The invention relates to a tungsten steel push rod and a processing method thereof. Background technique [0002] Tungsten steel push rod, also known as tungsten steel thimble, is often used in plastic molds to separate the workpiece from the mold. At present, the method of processing tungsten steel push rods generally adopts traditional manual turning, milling and grinding. The processed tungsten steel push rods cannot meet the accuracy requirements of each size, making it impossible to assemble or use tungsten steel push rods, resulting in tungsten steel push rods. The rod needs to be processed twice or scrapped directly, which increases the cost and prolongs the production cycle. Contents of the invention [0003] The object of the present invention is to provide a tungsten steel push rod, which has high dimensional accuracy, and its dimensional accuracy is still within the required accuracy range after repeated use. [0004] Another object of t...

At present, the method of processing tungsten steel push rods generally adopts traditional manual turning, milling and grinding. The processed tungsten steel push rods cannot meet the accuracy requirements of each size, making it impossible to assemble or use tungsten steel push rods, resulting in tungsten steel push rods. The rod needs secondary processing or direct scrapping, which increases the cost and prolongs the production cycle
