Abstract
The utility model relates to a hydraulic clamp which is used in forging equipment to clamp workpieces. The hydraulic clamp is composed of clamp arms, a clamp yoke and a hydraulic cylinder; wherein, the ends of the clamp arms are provided with jaws; the clamp arms include a moving clamp arm and a fixed clamp arm; the root of the fixed clamp arm is firmly connected with the clamp yoke; the middle bent part of the moving clamp arm is connected with the clamp yoke through a hinge shaft; the hydraulic cylinder is fixed on the clamp yoke; the stroke direction of the hydraulic cylinder is parallel to the opening direction of the jaws; and the end of the piston rod of the hydraulic cylinder is connected with the root of the moving clamp arm through a hinge shaft. The hydraulic clamp, which has the advantages of simple structure and convenient fabrication, sufficiently utilizes the stroke distance of the hydraulic cylinder, so that the clamping range of the hydraulic clamp is widened, and since the hydraulic clamp utilizes labor-saving leverage in the process of hydraulic transmission, the power loss is little, thus greatly enhancing the clamping force of the hydraulic clamp.
Description
Technical field
The utility model relates to a kind of hydraulic clamp that forges in the process equipment in order to holding workpiece.
Background technology
At present in the forging industry with the matching used workpiece clamp of forging manipulator, by hydraulic cylinder or cylinder its stroke power is passed to tong arm by pull bar, to change into the clamping power of tong arm, the stroke directions of hydraulic cylinder or cylinder is vertical with the clamping direction of clamp, and what use is generally all to be the effort lever, big in the loss of transmission process medium power, therefore clamping force is not ideal enough, and the part that tong arm links to each other with the cylinder bar of hydraulic cylinder or cylinder can only be swayed in the inside of pincers yoke cavity, usually in 30 degree, the clamping range of clamp is very restricted corner.
The utility model content
The technical problems to be solved in the utility model is: be the shortcoming and the deficiency that overcome prior art, the utility model provides a kind of clamping range wide, the forging hydraulic clamp that chucking power is stronger.
The technical solution adopted in the utility model is: a kind of forging hydraulic clamp, form by tong arm, pincers yoke and hydraulic cylinder, the tong arm head end is provided with jaw, described tong arm comprises fixedly tong arm of a movable tong arm and, fixedly the arm roots of tong arm is fixedlyed connected with the pincers yoke, and the bending place, middle part of movable tong arm is connected by hinge axis with the pincers yoke; Hydraulic cylinder is fixedly installed on the pincers yoke, and the stroke directions of hydraulic cylinder is parallel with the folding direction of jaw, and the piston rod head end of hydraulic cylinder is connected by hinge axis with the arm roots of movable tong arm.
Say further, described fixedly tong arm and the structure that clamps yoke employing integral type, integral casting forming is made with convenient, strengthens structural strength.
The beneficial effects of the utility model are: this hydraulic clamp structure is simple, and it is convenient to make, and it has made full use of the stroke distances of hydraulic cylinder, strengthened the clamping range of clamp, utilize laborsaving lever transmission in the hydraulic drive process, power loss is little, has strengthened the power of holding that adds of clamp greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. clamp fixedly tong arm 3. hydraulic cylinders of yokes 21. movable tong arms 22. among the figure
The specific embodiment
A kind of forging hydraulic clamp as shown in Figure 1, form by tong arm, pincers yoke 1 and hydraulic cylinder 3, the tong arm head end is provided with jaw, described tong arm comprises fixedly tong arm 22 of a movable tong arm 21 and, fixedly the arm roots of tong arm 22 is fixedlyed connected with pincers yoke 1, the bending place, middle part of movable tong arm 21 with clamp yoke 1 and be connected by hinge axis; Hydraulic cylinder 3 is fixedly installed on the pincers yoke 1, and the stroke directions of hydraulic cylinder 3 is parallel with the folding direction of jaw, and the piston rod head end of hydraulic cylinder 3 is connected by hinge axis with the arm roots of movable tong arm 21.
Fixedly tong arm 22 adopts integral structure with pincers yoke 1, and integral casting forming is made with convenient, strengthens structural strength.
This hydraulic clamp structure is simple, and it is convenient to make, and the stroke distances that it has made full use of hydraulic cylinder has strengthened the clamping range of clamp, utilizes laborsaving lever transmission in the hydraulic drive process, and power loss is little, has strengthened the chucking power of clamp greatly.
