Burnishing forming die for car seat headrest tube fitting

Abstract

The invention provides a burnishing forming die for a car seat headrest tube fitting, can solve the problem that tube surface collapse and tooth type perforation easily occur when the present ordinary tooth type forming die is adopted to process deep teeth, and can improve the processing efficiency effectively. The burnishing forming die comprises an upper die plate and a lower die plate which are guided to be closed through a sliding guide post component and is characterized by further comprising a burnishing forming die; the burnishing forming die comprises an upper die part and a lower die part; the upper die part is mounted on the upper die plate; the lower die part is mounted on the lower die plate; a burnishing forming male die is mounted in the lower die part; a deep tooth type burnishing forming male die is arranged on the burnishing forming male die and comprises three sequential tapered surface; the three sequential tapered plane comprises a tapered plane and conical surfaces at two ends of the tapered plane; and the conical surfaces at two ends of the tapered plane are connected with a deep teeth type burnishing forming male die plane through an inclined plane for transition.

Description

Technical field [0001] The invention relates to the technical field of forming and processing automobile seat pipe fittings, in particular to a tooth extrusion forming die for a car seat headrest pipe fitting. Background technique [0002] A car seat headrest tube, which is a U-shaped tube with continuous tooth openings on the inner side of one side of the tube wall, and one of the vertical tooth openings 33 has a tooth depth of 3.8 mm, and the thickness of the connecting part of the tube wall and the tooth plane It should not be less than 0.3mm. The deep tooth shape is processed by a common tooth forming mold. Because the pipe wall is thin and the material extension is not enough to meet the forming requirements of the pipe wall and the tooth plane, it is prone to collapse of the pipe surface and the pipe. The joint between the wall and the tooth plane is broken and perforated, which cannot meet the processing requirements; and the overall pressure of the tube after the tooth ex...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned problems, the present invention provides a tooth-extrusion forming die for the car seat headrest pipe fittings, which can solve the problems that the existing common tooth-shaped forming dies are easy to produce pipe surface collapse and tooth-shaped perforation when processing deep teeth, and can effectively improve Processing efficiency
