Abstract
The utility model relates to a centering mechanism of a forging press, which comprises a workbench. The centering mechanism is characterized in that two centering cylinders are respectively arranged on the left side and the right side of the workbench and are opposite to each other, a rod-less cavity of the left centering cylinder is connected with an oil inlet pipe, a rod-end cavity of the left centering cylinder is communicated with a rod-less cavity of the right centering cylinder through a pipeline, a rod-end cavity of the right centering cylinder is connected with an oil outlet pipe, and ends of piston rods of the two centering cylinders are connected with clamps. The centering mechanism has the advantages that during centering of cylindrical workpieces, hydraulic oil in the oil inlet pipe enters the rod-less cavity of the left centering cavity and pushes the piston rod of the left centering cylinder to move forwards, hydraulic oil in the rod-end cavity of the left centering cylinder is squeezed out by the piston rod, and enters the rod-less cavity of the right centering cavity through a pipeline, shifting distances of the left centering cylinder and the right centering cylinder are the same, and the clamps move synchronously, so that centering precision is guaranteed.
Description
Technical field
The utility model relates to a kind of forging press, particularly a kind of centering body of forging press.
Background technology
Forging press is hydraulic press or the punching machine that hot metal is forged.Traditional centering method has two kinds, and first kind is adopted range estimation, have human error; Perhaps adopt machinery back centering, it only has the direction can be right, and promptly left and right directions or fore-and-aft direction are difficult to entirely on the center.
Summary of the invention
The technical problem that the utility model will solve provides a kind of centering body of forging press simple in structure.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of centering body of forging press; Comprise workbench, its innovative point is: the and arranged on left and right sides of said workbench respectively is provided with a centering oil cylinder, and said left and right centering oil cylinder is provided with in opposite directions; The rodless cavity of left side centering oil cylinder is connected with oil inlet pipe, and its rod chamber is communicated with the rodless cavity of right side centering oil cylinder through pipeline, and the rod chamber of said right side centering oil cylinder is connected with flowline; The piston rod end of said centering oil cylinder all is connected with jig.
Further, said jig is a V-type, on two tops of jig roller is installed.
Further, be provided with isolation section between the piston rod of said jig and centering oil cylinder.
The advantage of the utility model is: when carrying out cylindrical work centering; Hydraulic oil in the oil inlet pipe gets in the rodless cavity of left centering oil cylinder, promote its piston rod reach, and the hydraulic oil in the rod chamber of left centering oil cylinder is extruded by piston rod; Get into the rodless cavity of right centering oil cylinder through pipeline; Make that the displacement of left and right centering oil cylinder is identical, the same moved further of jig has guaranteed accuracy of alignment.The end of jig is equipped with roller, if the position of workpiece has skew slightly, the end rollers of jig and workpiece are rolling friction, makes workpiece front and back centering, avoids jig and workpiece to scratch simultaneously.And be provided with isolation section between the piston rod of jig and centering oil cylinder, and avoid the high temperature workpiece that heat is passed to piston rod, improve the service life of centering oil cylinder.
Description of drawings
Fig. 1 is the centering body structural representation of the utility model forging press.
Fig. 2 is a jig vertical view in the utility model.
The specific embodiment
Like Fig. 1, shown in 2, comprise workbench 1, left centering oil cylinder 2, right centering oil cylinder 3, oil inlet pipe 4, pipeline 5, flowline 6, jig 7, roller 8, isolation section 9.
Above-mentioned workbench 1 each side be provided with a centering oil cylinder, this left side centering oil cylinder 2 is provided with right centering oil cylinder 3 in opposite directions.The rodless cavity of left side centering oil cylinder 2 is connected with oil inlet pipe 4, and its rod chamber is communicated with the rodless cavity of right centering oil cylinder 3 through pipeline 5, and the rod chamber of right centering oil cylinder 3 is connected with flowline 6.
The piston rod end of two centering oil cylinders all is connected with the jig 7 of clamping workpiece.This jig 7 is a V-type, on two tops of jig roller 8 is installed.Between the piston rod of jig 7 and centering oil cylinder, be provided with isolation section 9.
When carrying out cylindrical work centering; Hydraulic oil in the oil inlet pipe 4 gets in the rodless cavity of left centering oil cylinder 2, promote its piston rod reach, and the hydraulic oil in the rod chamber of left centering oil cylinder 2 is extruded by piston rod; Get into the rodless cavity of right centering oil cylinder 3 through pipeline 5; Make that the displacement of left and right centering oil cylinder is identical, two jigs 7 carry out the clamping centering of workpiece with moved further, have guaranteed accuracy of alignment.
Claims (3)
