Abstract

The invention discloses a casting and forging integrated device adopting a curved elbow connecting rod mode locking structure. The casting and forging integrated device adopting the curved elbow connecting rod mode locking structure comprises a lower mold plate, a vertical frame, a moving mold plate, an upper mold plate, a piston body, the curved elbow connecting rod mode locking structure, a cross head assembly, a forging bulge mold and a forging concave mold. One end of a vertical frame can be supported on the lower mold plate in a rotating mode; the moving mold plate sleeves the vertical frame and located above the lower mold plate, and can slide up and down along the vertical frame; the upper mold plate sleeves the other end of the vertical frame and is located above the moving mold plate, and can slide up and down along the vertical frame; the piston body is slidably arranged in the moving mold plate and can extend out of the moving mold plate; the curved elbow connecting rod modelocking structure is arranged between the moving mold plate and the upper mold plate; the cross head assembly is connected with the curved elbow connecting rod mode locking structure and can push thepiston body to move up and down; the forging bulge die is arranged under the piston body and can move up and down with the piston body; and the forging concave die is arranged on the lower mold plate. The curved elbow connecting rod mode locking structure is adopted, the force on the moving mold plate is good, the speed of mode opening and locking is stable, the mode locking force is stable, andreproducibility is good.

Description

technical field

[0001] The invention relates to an integrated casting and forging device, in particular to an integrated casting and forging device adopting a toggle link mold clamping structure. Background technique

[0002] Casting can form parts with complex shapes, but the structure density and mechanical properties of the parts are not high; the structure density and mechanical properties of forged parts are high, but the shape complexity of the parts is greatly limited. Therefore, for some structural parts with complex shapes and high mechanical properties, it is difficult for single casting and forging to play their advantages.

[0003] Casting and forging integrated forming technology is the combination of casting process and forging process. Firstly, the molten metal is injected into the mold by casting method, and then the metal is immediately forged in the same set of molds. The subsequent forging will eliminate the occurrence of the casting process. Shrinkage, p...

Embodiment Construction

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0054] Such as Figure 1-3 As shown, the integrated casting and forging device adopting the toggle link clamping structure provided by the present invention includes: a casting system 110 , a base 120 , a lower platen 130 , a movable platen 160 , an upper platen 170 and a toggle mold clamping system 200 .

[0055] The casting system 110 is a low-pressure automatic filling system, a low-pressure casting furnace, which is integrated under the integrated casting and forging device. When working, an air or inert gas pressure 0.01-0.05Mpa higher than atmospheric pressure is applied on the surface of the molten metal in the closed furnace body. The molten metal rises through the liquid riser dipped in the solution, and is pressed into the upper mold connected to the furnace through...
