Pneumatic trimming equipment for automobile interior trim part

Abstract

The invention discloses pneumatic trimming equipment for an automobile interior trim part. The pneumatic trimming equipment is formed by a trimming clamp and a plurality of trimming cutters. The trimming clamp is composed of a locating mechanism and a supporting frame. Each trimming cutter is composed of pneumatic shears and a shear type trimming cutter bit. The trimming cutters are arranged on the locating mechanism fixed to the supporting frame. The locating mechanism can be moved and adjusted horizontally and vertically on the supporting frame. Each pair of the pneumatic shears are composed of the shear type trimming cutter bit, a cutter body, a piston, a piston reset spring and a cutter bit reset spring. The cutter bodies are provided with piston cylinders. The pistons are arranged in the piston cylinders. V-shaped grooves are formed in the middle of the pistons. The shear type trimming cutter bits are hinged to the exteriors of the cutter bodies. Cutter handles of the shear type trimming cutter bits are arranged in the V-shaped grooves of the pistons. The piston reset springs are arranged on the peripheries of the cutter handles. The cutter bit reset springs abut against the inner sides of the two cutter handles. The top ends of the pistons abut against the lower ends of the piston reset springs. The cutter bodies are provided with through holes communicated with compressed air through air taps. The pneumatic trimming equipment is high in trimming speed and trimming quality, and suitable for operation in narrow space of the automobile instrument board center control trimming position.

Description

technical field [0001] The invention relates to a pneumatic trimming device for an automobile interior trim. Background technique [0002] The trimming methods of the leftover material of automotive interior parts include milling, punching and wallpaper knife trimming. [0003] 1. Milling: The operation intensity is small, but the equipment cost is high, the production cycle is long, the trimming time is long, and the trimming process is easy to produce burrs. [0004] 2. Punching: It has advantages in terms of operating strength, trimming quality, and working hours, but because it requires a large operating space, it has greater limitations in use. [0005] 3. Wallpaper knife trimming: low equipment cost and short production cycle, but its trimming quality is not easy to control, and it is difficult to meet the quality requirements when trimming special shapes. [0006] Because of the narrow space and unique trimming position of the center console of the car instrument pa...

AI Technical Summary

Problems solved by technology

[0003] 1. Milling: The operation intensity is small, but the equipment cost is high, the production cycle is long, the trimming time is long, and the trimming process is easy to produce burrs

[0004] 2. Punching: It has advantages in terms of operating strength, trimming quality, and working hours, but because it requires a large operating space, it has greater limitations in use

[0005] 3. Wallpaper knife trimming: low equipment cost and short production cycle, but its trimming quality is not easy to control, and it is difficult to meet the quality requirements when trimming special shapes

[0006] Due to the narrow space and unique trimming position of the instrument panel, the above three solutions are not ideal options.
