A device for plastic spraying of torsion bar and its plastic spraying method

Abstract

The invention discloses a device for plastic spraying of a torsion bar and a plastic spraying method thereof. The device comprises a box, plastic powder spray heads, a pair of motors and a pair of clamping mechanisms for wrapping and clamping the spline portions at the ends of the torsion bar. The motors are fixed to the two opposite sides of the box respectively, the clamping mechanisms are fixed to rotary shafts of the motors, and the plastic powder spray heads are located above the position between of the clamping mechanisms. The plastic spraying method comprises the following steps that the spline portions at the two ends of the torsion bar are placed in clamps of the clamping mechanisms at the two sides respectively; air cylinders of the clamping mechanisms work, and the spline portions at the two ends of the torsion bar are wrapped and clamped; the motors work at the same time, the torsion bar is driven to rotate, and the plastic powder spray heads are started to carry out plastic spraying on the torsion bar. Automatic plastic spraying is carried out in the box, operation is easy and convenient, and production efficiency is high.

Description

Technical field [0001] The invention relates to the technical field of torsion bar production, in particular to a device for spraying plastic torsion bars and a spraying method thereof. Background technique [0002] Both ends of the torsion bar are splines, and the body of the torsion bar between the two ends of the splines needs to be sprayed with plastic powder, and it is required that no plastic powder is sprayed on the splines. [0003] When spraying plastics, most of the existing splines are covered by sheaths (such as paper sleeves, plastic sleeves, iron sleeves) at both ends of the torsion bar. The installation and removal of the sheath is cumbersome, the production efficiency is low, and the spline parts are prone to leaks. If the sleeve or the package is not in place, the spline part is sprayed with plastic powder; when spraying, the torsion bar body between the two ends of the spline needs to be positioned, and the positioning part is of poor quality; the existing manual ...

Problems solved by technology

[0003] When spraying plastic, most of the splines at both ends of the torsion bar are covered by sheaths (such as paper sleeves, plastic sleeves, and iron sleeves). The installation and removal of the sheaths is cumbersome, the production efficiency is low, and the splines are prone to leakage. If the cover or cover is not in place, the spline part is sprayed with plastic powder; when spraying, it is necessary to position the torsion bar body between the splines at both ends, and the quality of the positioning part is poor; the existing method is to manually hold the spray gun Manual plastic spraying, the working environment of workers is extremely poor, which affects the health of workers, artificial spraying is uneven, and the quality of spraying is poor
