Press moveable platform for elastic element unloading

Abstract

The invention discloses a moving worktable of the pressing machine of the elastic element unloading in the pressing machine field, which comprises a working plate, and a moving supporting bracket is arranged under the working plate. A leader is used to guide between the working plate and the moving supporting bracket, a pre-compressing elastic element is sleeved on the leader, and the upper and lower ends of the elastic element are respectively propped on the working plate and the moving supporting bracket. Rollers are arranged at two sides of the moving supporting bracket, and the rollers are supporting on the linear guide of the circular cross-section. Cylinders or hydraulic cylinders are respectively arranged at two sides of the moving supporting bracket, and the cylinder bodies of the cylinders or the hydraulic cylinders are fixed with the bed, and the piston extending end of the cylinder or the hydraulic cylinder is fixed with the moving supporting bracket. A padding plate is arranged under the working plate, and an obligated clearance is arranged between the two. When the worktable endures the function of the clamping force, the elastic element is compressed, and the working plate is pressed on the padding plate directly. The moving worktable of the pressing machine has the advantages of enabling the molds to move between two stations and locate automatically, supporting a certain clamping force, and satisfying the reinforcing reaction for injection forming of the long glass fiber of the automobile ornament.

Description

technical field [0001] The invention relates to a press, in particular to a workbench of the press. Background technique [0002] In the general pressure forming process, the workbench of the press has the following two forms: [0003] (1) The workbench of the press is fixed [0004] When this kind of press is working, the process equipment for forming is directly installed on the fixed workbench, and the clamping pressure during the forming process is directly transmitted to the press body through the mold, and there is no problem of movement or positioning of the workbench. [0005] (2) The worktable of the press can be moved [0006] This kind of press is mainly to meet the needs of the forming process. The workbench generally has two stations, and one station is used for various auxiliary operations, such as cleaning the mold, loading materials, and taking parts. [0007] In order to realize the movement and positioning of the workbench between the two stations, the w...

AI Technical Summary

Problems solved by technology

[0015] ① The overall structure is relatively complex, especially the lifting mechanism of the worktable used to withstand sufficient forming pressure or clamping force needs to be driven by four oil cylinders. The synchronization accuracy of the oil cylinders brings great pressure to the design and manufacture. The setting of oil pipes Also affects the appearance of the press;

[0016] ② There are many links in the guiding mechanism itself, and at the same time, it is limited by the guiding method, resulting in low guiding accuracy;

[0017] ③The lifting stroke of the worktable is relatively large, which affects the effective working stroke and application range of the press

[0023] Due to its inherent defects, the movable table of the existing press cannot meet the long glass fiber reinforced reaction injection molding process of automotive trim parts
