Abstract

The invention discloses a machine head component of a tubing thread forming machine. The machine head component comprises a support, forming moulds and transmission devices of the forming moulds. Each forming mould comprises a forming sleeve, and a support frame and a thread forming member which are sleeved on the forming sleeve, and the machine head component of the tubing thread forming machine is characterized that a plurality of forming moulds are arranged on the support; a block plate is arranged on the front end surface of the support frame; a hollow hole is arranged in the block plate corresponding to the inlet end of the forming sleeve; one or three radial sliding grooves are uniformly arranged on the circumference of the support frame; a wedge slider of which the top surface is high above the sliding grooves is arranged in the sliding grooves, and the wedge slider slides along the sliding grooves; the thread forming member is connected integrally with the slider; a rotary support sleeve is connected to the rear end of the support frame; and a movable jacket is arranged on the outer side of the rotary support sleeve. Compared with the machine head component of the conventional tubing thread forming machine, the machine head component provided by the invention is high in production efficiency and machining accuracy, and is variable in production product; and moreover, the problems that the stress of the tube is excessively concentrated and the tube is easy to fracture are solved.

Description

technical field [0001] The invention relates to a pipe thread forming machine, in particular to a head assembly of a pipe thread forming machine. Background technique [0002] The head assembly of the existing pipe thread forming machine generally includes a bracket, a molding die and a transmission device arranged on the bracket, so only one pipe production line is formed, and the production efficiency is low. The forming mold includes a forming sleeve, a support frame set on the forming sleeve, and a threaded part on the support frame. The threaded part defines conditions such as the pipe diameter and the depth of the thread on the pipe, so the structural form of the threaded pipe has limitations. Not suitable for diverse market demands. In addition, during processing, the pipe rotates, the forming die moves along the length of the pipe, and the stylus forms threads on the pipe wall. Such a processing method is unfavorable for cold-worked pipes. Under the same torsional ...
