A step-by-step wire tapping device for earmarking plastic parts

Abstract

The invention discloses a stepping tapping device for an ear tag injection molded part. The stepping tapping device comprises a base plate, a motor, a rocker, a driving rod and a turntable frame; a limiting guide support is arranged at the corner of the base plate; a guide column is arranged on the limiting guide support; a pneumatic tapping machine is arranged in the middle of the edge of the base plate; the motor is connected to the lower end of the base plate through bolts; one end of the rocker is connected to an output shaft of the motor, and the other end of the rocker is hinged to the lower part of the drive rod; a long groove is formed in the driving rod and can slide under the limit of the guide column; and the turntable frame is connected to the base plate in a rotating mode. Thestepping tapping device has the advantages that the stepping tapping operation can be carried out after a male ear tag body is subjected to injection molding, the tapping efficiency is high, the thread consistency is good, and the adjustment of changing the thickness of a tag pole of the male ear tag body can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of processing equipment for injection molded parts, in particular, the invention relates to a step-by-step wire tapping device for ear tagging plastic parts. Background technique [0002] Now, in order to change the thickness of the rod on the standard rod of the animal ear tag with the growth cycle of the animal, it is necessary to tap the thread at the concentric position of the injection molded standard rod. The traditional method is to directly use the mold for injection molding, but there will be injection molding at the mold closing position. The generated burrs make the continuity of the thread very poor, and it is inconvenient to screw in and out of the tension column during use. Contents of the invention [0003] The invention provides a step-by-step tapping device for ear marking plastic parts, which realizes the step-by-step tapping operation after standard marking and molding, has high tapping ...
