Sponge slicing method and sponge slicing fixing device for automobile cushion

Abstract

The invention discloses a sponge slicing method for an automobile cushion. The sponge slicing method comprises a longitudinal cutting step and a transversal cutting step, wherein during longitudinal cutting, sponge is longitudinally flattened, and then the longitudinal cutting is carried out on the sponge in the flattened state by virtue of a cutting device; and during transversal cutting, the sponge is inflated by virtue of an inflator, and the transversal cutting is carried out on the sponge by virtue of a cutting device. According to the sponge slicing method disclosed by the invention, during the longitudinal cutting, a piston is pressed by a hydraulic cylinder to flatten the sponge to be cut in a compression barrel, and then the cutting is carried out, so that the displacement and the deformation of the sponge generated during the cutting process can be avoided; during the transversal cutting, a rubber film is arranged on the sponge to be cut in a sleeving manner by virtue of an elastic band, a connection valve is opened, the inflator inflates the sponge, at this moment, the sponge has a certain hardness due to inflation inside and cannot generate large-amplitude deformation during the cutting, and a fixing plate is extruded by a spring to be abutted against the sponge to further realizing fixing; and the two manners improve the cutting accuracy of the sponge.

Description

technical field [0001] The invention relates to the field of raw material processing, in particular to a method for cutting sponges for automobile seat cushions and a cutting and fixing device. Background technique [0002] As the most important means of transportation, with the continuous development of technology, the comfort level of automobiles is also increasing. The most important thing is the cushion sponge, but the raw material of the cushion sponge is a whole piece of sponge, which needs to be cut into suitable It is made into the shape of a cushion, but because of its softness and easy-to-deform physical properties, the sponge is prone to displacement and deformation during cutting with a cutter, resulting in large processing errors. [0003] In the patent specification with the publication number CN103568065B, a sponge cutting machine is disclosed based on servo motor detection and fine-tuning of the control method of the parallelism of the guide rails, using the ...

AI Technical Summary

Problems solved by technology

Not only the structure is complicated, but also the sponge to be cut cannot be fixed, which will still cause large errors
