A leather carving hydraulic device and embossing method

Abstract

The invention relates to a leather carving hydraulic device and an embossing method. The device includes a frame, a hydraulic jack, an upper pressing plate and a lower pressing plate. A plurality of guide columns, the upper platen is set on the top of the frame and is located directly above the lower platen; the lower platen and the upper support plate are provided with a seal ring structure that cooperates with each other, and the seal ring structure makes the lower platen and the upper platen A closed cavity is formed between the working surfaces of the pressing plates, and the upper pressing plate or the lower pressing plate is provided with exhaust holes, and the exhaust holes are used to communicate with the negative pressure generating device through the air channel. The method is an embossing method in which the embossing operation is performed using the above-mentioned device.

Description

technical field [0001] The invention relates to the field of embossing mechanical equipment and leather carving and embossing technology, in particular to a leather carving hydraulic device and an embossing method. Background technique [0002] Leather products are daily necessities made of genuine leather or artificial and synthetic leather. Genuine leather is a fur product obtained from natural animal skin through different tanning processes. The surface color and luster of existing ordinary leather products can only stay within the framework of tradition, rigidity, mediocrity and similar styles, while leather printing technology only It can be completed with a full-page printing process in the tannery, which greatly affects the personalized expression and richness of the surface patterns and flower shapes of fur products, which is far from satisfying people in the modern market in terms of clothing and decoration. requirements.

Genuine leather is a fur product obtained from natural animal skin through different tanning processes. The surface color and luster of existing ordinary leather products can only stay within the framework of tradition, rigidity, mediocrity and similar styles, while leather printing technology only It can be completed with a full-page printing process in the tannery, which greatly affects the personalized expression and richness of the surface patterns and flower shapes of fur products, which is far from satisfying people in the modern market in terms of clothing and decoration. requirements

[0003] The leather carving hydraulic device in the prior art has a relatively simple structure, and the upper and lower pressing plates cannot be guaranteed to be even during the process of applying pressure, so the embossing force is uneven; when applying pressure, only by operating the hydraulic jack, and according to the operator's experience and manual It is unscientific and inaccurate to judge the internal strength, which will lead to a large difference in the specific effect of each embossing; after the embossing is completed, the leather block needs to be dried, and the embossing will produce rebound to a certain extent during the drying process. Shrinkage and other deformations affect the effect
