Semi-closed high-pressure chamber device of metal packing hydraulic press
Technical field
The present invention relates to a kind of parts of metal packing hydraulic press, particularly a kind of semi-closed high-pressure chamber device of metal packing hydraulic press.
Background technology
Existing metal packing hydraulic press hyperbaric chamber is made of jointly base, side arm, left and right side frame and cover.As shown in Figure 3, this conventional high-tension cell structure is provided with a retaining mechanism at side arm, weak point is: the expansive force when finally forming for overcoming enclosed mass, the retaining mechanism of installing in the side arm is after cover closes lid and puts in place, lock pin ejects its locking, and that lock pin bears cross force is bigger, has lock pin distortion and leakage of oil problem after long-term the use.
Summary of the invention
Technical problem to be solved by this invention provides a kind of semi-closed high-pressure chamber device of metal packing hydraulic press, can solve existing lock pin distortion and leakage of oil problem, makes the machine construction compactness, and prolongs the service life of machine.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of semi-closed high-pressure chamber device of metal packing hydraulic press, comprise main pressure head, side pressure head, and side arm, base, left frame and left side frame are welded to connect.
Put up inverted "L" shaped before described.
Be provided with push-pressure head in the described side arm.
Described push-pressure head is installed in the position relative with the side pressure head.
A kind of semi-closed high-pressure chamber device of metal packing hydraulic press provided by the invention, the side arm of base bogie side frame, left and right bogie side frame and inverted "L" shaped is welded together to form a semienclosed hyperbaric chamber, old metal forms enclosed mass under the extruding of side pressure head and main pressure head, release the hyperbaric chamber by push-pressure head then, this is simple and compact for structure, reliability and durability, solved the problem of lock pin distortion of existing hyperbaric chamber and leakage of oil.

The specific embodiment
A kind of semi-closed high-pressure chamber device of metal packing hydraulic press, in Fig. 1, it is the hyperbaric chamber that the side arm 1 of inverted "L" shaped, base 2, left frame 5 and left side frame 6 form a semienclosed high pressure packing district by welding, the push-pressure head 4 of tape guide plate is installed in the side arm, and push-pressure head 4 back are provided with a hydraulic cylinder.The side arm 1 of inverted "L" shaped has accounted for two faces in six faces in hyperbaric chamber, side pressure 3 is relative with a face of side arm 1, and it is relative with left frame 5 that main pressure head 7 is contained in left side frame 6 places.
In Fig. 2, the course of work of the present invention is as follows: side pressure 3 is clamp-oned this semienclosed hyperbaric chamber with old metal, pushed by main pressure head 7 and form enclosed mass, side pressure 3 and main pressure head 7 are backed out, and the enclosed mass of shaping is released the hyperbaric chamber by the Driven by Hydraulic Cylinder push-pressure head 4 that is installed in the side arm 1 with it.
