Problems solved by technology

[0002] As we all know, one of the traditional thread processing methods is to select the material that has been stamped and formed to be processed, and then cut the required thread (ie tapping) by hand or machine tool, and finally form the product. Two operations, therefore, the production efficiency is not very high, coupled with the tapping operation alone, the strength of the cutting thread is difficult to be well guaranteed, and the cutting chips will also have a certain impact on environmental sanitation, so need to be improved

Embodiment Construction

[0010] The present invention is implemented according to the above-mentioned technical scheme. The strip material to be tapped is a metal strip material, generally small hole tapping, and the rack is fixed on the lower mold of the mold by the rack holder, and two pieces of polyurethane are used in the rack holder. The rack is clamped by grease rubber, which can play a good role in shock absorption and protection.

[0011] The present invention can add a plurality of transmission gears and transmission boxes, so that tapping can be performed on multiple positions at the same time.

[0012] The invention completes tapping simultaneously in the stamping process, which organically integrates traditional stamping and tapping technologies, effectively changes the traditional production method of "stamping first and then tapping", and greatly improves production efficiency. The production cost is reduced and the economic benefit is increased.

Abstract

The invention relates to a progressive mold and tapping device which is characterized in that a gear box assembled on the upper mold is connected with a transmission box via a transmission gear. The top of the transmission shaft in the transmission box is provided with a tap. A gear rack fixed on the lower mold is coordinated with the gear in the gear box. When the upper mold moves downward, the gear box changes the straight line motion of the punch to the rotating motion, and changes the direction and velocity for enabling the tap on the transmission shaft to rotate and simultaneously move downward to tap the preserved through hole on the belt material, thus the tapping is simultaneously completed during the punching process, thereby changing the traditional production mode of firstly punching and secondly tapping, enabling the production efficiency to be greatly increased, decreasing the cost and increasing the economical effect.

Description

technical field [0001] The invention belongs to a progressive die belt tapping device in a stamping die. Background technique [0002] As we all know, one of the traditional thread processing methods is to select the material that has been stamped and formed to be processed, and then cut the required thread (ie tapping) by hand or machine tool, and finally form the product. Two operations, therefore, the production efficiency is not very high, coupled with the tapping operation alone, the strength of the cutting thread is difficult to be well guaranteed, and the cutting chips will also have a certain impact on environmental sanitation, so needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a progressive die belt tapping device in which the progressive die can simultaneously tap on the metal strip in the stamping process. [0004] The present invention utilizes the linear motion of the punching machine to convert it ...
