Flat suction machining method for circular PIN part

Abstract

The invention discloses a flat suction machining method for a circular PIN part. The flat suction machining method comprises the steps of selecting a suction magnetic table and placing the suction magnetic table on a magnetic table of a machine tool; fixing an ejector block and a first stop block on a suction magnetic table according to the machining length of the to-be-machined end of the circular PIN part; placing the to-be-machined end of the circular PIN part on the suction magnetic table, and making the top surface of the circular PIN part in contact with the block; placing a second stopblock on the opposite side of the first stop block, and making the first stop block and the second stop block clamp the length direction of the circular PIN part; placing a metal press block for pressing the circular PIN part on the first stop block and the second stop block; assembling a handle for rotating the circular PIN part at the unmachined end part of the circular PIN part, and then trimming a grinding wheel; and switching on the suction magnetic table, the magnetic table of the machine tool and a main shaft of the machine tool, and then rotating the circular PIN part to make contact with and be ground by the moving grinding wheel by using the handle until the to-be-machined end meets the design requirement of a drawing.

Description

technical field [0001] The invention relates to the processing technology of circular PIN needle parts, in particular to a flat suction processing method of circular PIN needle parts. Background technique [0002] In the processing of mold parts, round PIN needles are often processed, and round PIN needles are usually processed by punch formers (commonly known as: twisted circles). The chuck of the punch former clamps one end of the round PIN needle, and the other end is suspended Make the grinding wheel of the grinder touch the suspended part to achieve the shaping effect. However, after the circular PIN needle is suspended in the above processing method, there will be the following defects during processing: [0003] ①The clamping time is too long, and it needs to be leveled with a calibration table, which wastes auxiliary time. ②The concentricity of the front and rear ends of the processed circle will deviate, and the circle is prone to conical circles. ③ If the amount...

AI Technical Summary

Problems solved by technology

[0003] ①The clamping time is too long, and it needs to be leveled with a calibration table, which wastes auxiliary time

②The concentricity of the front and rear ends of the processed circle will deviate, and the circle is prone to conical circles

③ The amount of cutting knife is not uniform, there will be uneven heating, and the size is not easy to control

④The contact point is too small, and the machine tool is running at high speed, causing the circular PIN needle to jump easily when rotating (commonly known as: spring knife), and a flat section will appear on the circular PIN needle, which is scrapped

[0004] To sum up, the processing time of parts is too long, and the quality is not easy to control, resulting in high cost of parts processing
