Problems solved by technology

[0003] However, the existing handrails mainly use polyurethane foaming technology to achieve the soft touch effect, but it requires early equipment investment and the development of foaming molds. Not only is the research and development cycle long and expensive, but the entire production process takes a long time. Masking paper needs to be pasted to prevent material leakage, foaming, polishing and flashing, etc. The processing efficiency is low and the production cost is high

Embodiment 1

[0081] A production process for an automobile armrest, comprising the following processing steps:

[0082] Step A, choose and buy leather material and sponge; The thickness of described leather material is 2mm, and the thickness of sponge is 4mm;

[0083] Step B, cutting the leather and sponge according to the shape of the upper cover of the car armrest, so that the surface of the leather and sponge completely covers the surface of the upper cover of the car armrest, and the surface area of ​​the leather and sponge is greater than the surface area of ​​the upper cover of the car armrest;

[0084] Step C. Use a pneumatic spray gun to spray glue on one of the surfaces of the sponge. The air pressure of the pneumatic spray gun is 0.6mpa. After spraying glue, it is baked in a flat oven. The baking temperature is 55°C and the baking time is 60s. Then Paste the surface of the sponge sprayed with glue on the upper surface of the upper cover of the car armrest, so that the sponge is e...

Embodiment 2

[0093] A production process for an automobile armrest, comprising the following processing steps:

[0094] Step A, choose and buy leather material and sponge; The thickness of described leather material is 3mm, and the thickness of sponge is 5mm;

Abstract

The invention relates to the field of automobile part manufacturing technologies, in particular to an automobile handrail manufacturing technology. The technology comprising the following processing steps: (1) selectively purchasing a leather material and a sponge, (2) tailoring the leather material and the sponge according to the shape of an outer cover of an automobile handrail, (3) spraying glue on and baking one surface of the sponge so as to enable the sponge to wrap the surface of the upper cover of the automobile handrail smoothly, (4) prebaking the leather material, and then spraying glue and baking, for the second time, one surface of the material so as to enable the leather material to wrap the upper surface of the sponge smoothly, (5) stretching the leather material and the sponge along the edge of the leather material and the edge of the sponge so as to enable the leather material and the sponge to be smooth, using a staple gun to nail for fixation, and shearing off the surplus leather material and the surplus sponge, (6) assembling the upper cover, of the automobile handrail, processed in the last step to a handrail seat so as to obtain the automobile handrail. The automobile handrail manufacturing technology is simple and mature and has the advantages of being high in processing efficiency and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of production of automobile parts, in particular to a production process of an automobile handrail. Background technique [0002] With the rapid development of modern automobile technology, in order to improve the utilization rate of the limited space in the car, people usually set up a seat armrest between the two car seats for the driver or passenger to rest their hands on it, and put paper towels, fuel tickets, etc. Such sundries are stored in the storage space of the seat armrest to save space. In this way, the armrest of the seat armrest needs to be opened frequently. In order to improve the comfort of the seat armrest and effectively reduce the wear and tear of the armrest, it is usually necessary The upper surface is covered with a leather case to prolong the service life of the armrest and improve the comfort of the armrest. [0003] However, the existing handrails mainly use polyurethane foaming te...
