Description

A hydraulic pressure pressfitting machine for production of protective shoes Technical Field The invention relates to the technical field of shoe production equipment, in particular to a hydraulic pressing machine for producing protective shoes. Background In the production of protective shoes (such as safety shoes and labor shoes), the bonding of uppers and soles through adhesives is a key process for determining the peeling strength and safety performance of finished products, and currently, hydraulic bonding machines are commonly adopted in the industry to perform the process, and the main flow structure of the hydraulic bonding machines generally comprises a vertically downward pressing gantry type bonding machine or a lateral pressing machine for directly pressing from the lateral direction. However, the prior art press-fit method has significant drawbacks in that the bonding surface (particularly the transition region between the sole edge and the upper sidewall) is often provided with gaps or uneven glue layers after the adhesive-coated sole and upper are initially aligned during the press-fit process. The traditional vertical or unidirectional lateral pressing is single in force application direction and fixed, pressure directly acts on one direction of the vamp or the sole, the adhesive at the edge of the sole is difficult to effectively spread and drive towards the central area, the adhesive cannot be uniformly extruded and spread, the local area can be too thick or too thin in the adhesive layer, air bubbles are easy to remain in the seam between the arc-shaped curved surface of the sole and the upper, the final adhesive strength of the sole and the upper is finally caused to be not up to standard, the durability and the safety of the protective shoe are seriously influenced, and the quality problems of glue opening, bottom falling and the like can occur under severe working environment. Therefore, there is a need for a novel hydraulic press-fit device capable of dynamically adjusting the force application angle and direction during the press-fit process, actively flattening the adhesive from the edge to the center, and ensuring complete fit between the upper and the curved surface of the sole, so as to fundamentally improve the press-fit quality and production efficiency of the protective shoes Disclosure of Invention The invention aims to provide a hydraulic pressing machine for producing protective shoes, which solves the problems in the prior art.
