Pressing machine

Abstract

The invention discloses a pressing machine which comprises a welding machine body, wherein reinforcing plates are respectively welded on the two sides of a left wall plate and a right wall plate of the welding machine body; each reinforcing plate comprises a guide rail reinforcing part used for reinforcing the guide rail mounting area, a platform reinforcing part used for reinforcing the area below a working platform, and a middle reinforcing part used for reinforcing the wall plates between the guide rail and the working platform, and the three parts are integrally formed. With the adoption of the technical scheme, the welding body is light in weight, saves materials, and is low in cost, small in deformation if being in long-term heavy-load operation, and low in manufacturing cost.

Description

technical field [0001] The invention relates to a press, in particular to a reinforcement structure for a stress concentration area of ​​a mechanical press fuselage. Background technique [0002] The press is a general-purpose equipment widely used in industrial production such as forging. The press body can be divided into casting type and welding type. The casting type fuselage has good overall strength, but it is heavy and expensive. The welded fuselage is widely used because of its light weight, less material waste, and low cost. However, during stamping, due to the reaction force, the fuselage body is easily deformed, and even the welded parts are broken, which seriously affects the parts of the fuselage. The service life of parts and molds increases the production cost, and the accuracy of the product cannot be guaranteed. In order to make up for this defect, the manufacturing method of thicker materials is generally used, which in turn increases the consumables of th...

The overall strength of the cast fuselage is good, but it is heavy and expensive

The welded fuselage is widely used because of its light weight, less material waste, and low cost. However, during stamping, due to the reaction force, the fuselage body is easily deformed, and even the welded parts are broken, which seriously affects the parts of the fuselage. The service life of parts and molds increases the production cost, and the accuracy of the product cannot be guaranteed. In order to make up for this defect, the manufacturing method of thicker materials is generally used, which in turn increases the consumables of the fuselage, the weight of the whole machine, and the production cost. improve
