Turntable-type multi-station pen point automatic processing machine tool with pipe contraction function

Abstract

The invention discloses a turntable-type multi-station pen point automatic processing machine tool with a pipe contraction function. An upper tool body, a lower tool body and a rotary workbench are arranged in a machine cover; a plurality of stations are an upper row of processing mechanisms and a lower row of processing mechanisms and are distributed above and below the rotary workbench; the processing mechanisms perpendicularly process a pen material; the rotary workbench can rotate the pen material to the next station; the processing mechanisms are arranged at the tail end of a power head; the processing mechanisms are provided with a transmission mechanism and power equipment which are used for driving the workbench to rotate and the power head to move, an oil spraying mechanism, an oil pump set, an oil tank, a control cabinet and a pipe contraction mechanism arranged on the power head; the oil spraying mechanism, the oil pump set and the oil tank are used for spraying oil towards the tool bodies; the pipe contraction mechanism comprises a ball seat and at least three balls; the balls are accommodated in the ball seat; the pipe contraction mechanism precisely compresses pipe materials through rotation and revolution of the balls; the surface of the contracted pipe is smooth; the pipe contraction mechanism is suitable to contract a needle pipe pen point; and therefore, the turntable-type multi-station pen point automatic processing machine tool can manufacture a bullet-type pen point and is applicable to pipe contraction of a needle pipe pen point.

Description

technical field [0001] The invention relates to a nib processing equipment, in particular to a turntable multi-station nib automatic processing machine tool with tube shrinking function. Background technique [0002] At present, the domestic production of ballpoint pen nibs generally uses multiple machine tools to complete turning, drilling, and testing in separate processes, and then perform beading and closing processes on several other machine tools. The processing accuracy is poor and the production efficiency is low. The use of space is wasteful; for these problems, there was once a linear chain type multi-station automatic processing machine tool, but the diameter of the ball ball of the processing pen head has limitations, low processing accuracy and poor reliability. [0003] At present, the machine tool with high processing precision is mainly the 24-station machine tool model of Swiss MIKRON (Mikron). This 24-station machine tool has 24 stations, a total of 48 pro...

Problems solved by technology

The traditional tube shrinking method of the needle pen tip is die extrusion, that is, a mold is set first, and then the tube material is squeezed at one end of the mold to achieve the purpose of shrinking the tube. This shrinking method of mold extrusion has the following defects: 1. 1. It is easy to cause the surface of the pipe material to be uneven, and it is easy to have burrs; 2. Pipe materials with different diameters require different molding dies, resulting in an increase in cost
