Casting-forging hydropress and method for casting and forging product thereof

Abstract

The invention discloses a casting-forging hydropress and a method for casting and forging a product thereof. The casting-forging hydropress comprises a worktable, a stand column, a die-assembling cylinder, a forging and pressing cylinder, a movable beam and a pressure casting device, wherein the stand column is arranged on the worktable, the die-assembling cylinder is arranged on the stand column, the movable beam is movably arranged on the stand column and connected with a piston rod of the die-assembling cylinder, the forging and pressing cylinder is arranged on the die-assembling cylinder, and the pressure casting device is arranged on the tabletop of the worktable. According to the invention, as the pressure casting device is arranged on the tabletop of the worktable, a die can be filled with metal liquid not just in the state of die opening, thereby facilitating the filling and pressure feeding of the metal liquid, and simplifying the operation process, so that the operating efficiency of the hydropress is effectively improved; meanwhile, as a cylinder body of the forging and pressing cylinder is formed by hollowing out the lower end of the piston rod of the die-assembling cylinder, the structure of the hydropress is simplified, and the hydropress has the advantages of high forging pressure and stable die-assembling pressure and the like, thereby effectively ensuring the forging performance of products.

Description

technical field [0001] The invention relates to a machine in the metal forming industry, in particular to a casting and forging hydraulic press integrated with metal side feeding pressure casting and forging and a method for casting and forging products thereof. Background technique [0002] As we all know, in order to obtain metal parts of a certain shape, size and mechanical properties, casting, forging, welding and various machining processes are usually used. For parts with complex shapes and low mechanical performance requirements, the general casting method can be used; for parts with high mechanical performance requirements but not very complicated shapes, forging and machining must be used; but for high performance requirements and shape And very complicated parts, will carry out a large amount of and complex mechanical processing after forging, and like this, not only consume a large amount of precious metal materials, but also consume a large amount of energy and p...

Problems solved by technology

The disadvantages of this die-casting forging machine are: 1. The die-casting device is arranged on the lower part of the workbench, and the die-casting forging machine must be in the state of opening the mold before pouring and charging the injection barrel through the fixed mold, which is very inconvenient to operate, thus As a result, the working efficiency of the equipment is low, and the high-speed filling process will cause splashing and air entrainment of the molten metal, so the product quality and yield are relatively low; 2. The forging function of the die-casting forging machine is realized by forging the transmission connecting rod , the forging pressure and forging deformation are relatively low, so the forging performance of the product is poor
