Problems solved by technology

The rigidity of the three-beam four-column structure press is relatively poor, and the accuracy cannot be guaranteed
The powder metallurgy press modified by the general-purpose frame-type hydraulic press does not take into account the pressing characteristics of the powder parts. The pressing mode is the same as that of the ordinary hydraulic press, and the pressing action cannot be set according to the best pressing curve of various powders. It is difficult to achieve the best suppression effect
[0003] Whether the special powder metallurgy presses currently in use are imported or domestic, the structure is too complicated, the volume is huge, and the price is too high, which makes most powder metallurgy enterprises discouraged.

Embodiment Construction

[0014] The present invention is described below in conjunction with the accompanying drawings, but the scope of protection claimed by the present invention is not limited to the scope mentioned in this embodiment.

[0015] figure 1 As shown, the press includes the following parts: 1. Upper cylinder, 2. Frame, 3. Drive cylinder for die table, 4. Guide column, 5. Lower template, 6. Core rod template, 7. Core rod drive cylinder, 8. Lower template drive cylinder, 9. Mold platform, 10 upper beams, 11 upper formwork, 12 upper formwork drive cylinders, 13 top plate, 14 bottom plate. The mold base of this press adopts the upper two and lower three mold bases. Each layer of formwork and mold table is driven by two oil cylinders symmetrically arranged.

[0016] There are two upper templates 11, one is driven by two symmetrically arranged upper template driving cylinders 12, and the upper template driving cylinders 12 are suspended and installed on the upper part of the press; the othe...

Abstract

The invention discloses a kind of powder metallurgy press for driving side mould bracket integration. The press mainly includes top board, frame, oil cylinder driven by mould plat, the subjacent mould board, the subjacent template drives the oil cylinder, mould desk, a upper beam, a bottom board, a upper template and oil cylinder driven by template, the mould desk is set on the frame, one end is set on the bottom of the top board, the other end is connected with the upper template, one side of it is connected with the upper beam, there has an air gap between the other side and the inner wall of the frame; the oil cylinder driven by the subjacent board is set in the frame, one end is fixed on the top of the bottom board, the other end is connected with the template, there has an air gap between the cylinder and frame. The invention has a low cost.

Description

technical field [0001] The invention relates to a powder metallurgy press, in particular to a powder metallurgy press integrated with drive side formwork. Background technique [0002] At present, domestic powder metallurgy presses often adopt a three-beam and four-column structure, or use a general-purpose frame-type hydraulic press for modification. The rigidity of the three-beam four-column structural press is relatively poor, and the accuracy cannot be guaranteed. The powder metallurgy press modified by the general-purpose frame-type hydraulic press does not take into account the pressing characteristics of the powder parts. The pressing mode is the same as that of the ordinary hydraulic press, and the pressing action cannot be set according to the best pressing curve of various powders. It is difficult to achieve the best suppression effect. [0003] Whether the special powder metallurgy presses currently in use are imported or domestic, the structure is too complicat...
