Problems solved by technology

[0003] During the forging process of the precision forging machine, there are often gaps with indeterminate directions in each component. These gaps make the parts collide with each other continuously in the cycle of forging and stopping forging, which reduces the service life.
At the same time, the position of the hammer head during forging is inconsistent with the position of the hammer head during adjustment, which reduces the dimensional accuracy of the product

Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, the eccentric sleeve adjusts the reduction amount of the hammer head of the precision forging machine, which is to fix one end of the eccentric sleeve 4 on the rotation center O of the frame 1 of the precision forging machine 2 , the hammer head driven by the eccentric shaft is located at O ​​of the non-rotation center of the frame 1 place.

[0014] The slider 2 is fixedly connected to one end of the pull rod 3, and the other end of the pull rod 3 is fixed to the outside of the eccentric sleeve 4, and the motor drives the slider 2 to move, thereby driving the eccentric sleeve 4 to rotate, and adjusting the hammer head depression.

[0015] There are gaps between the eccentric sleeve 4 and the frame 1, and the slide block 2 to its driving motor. Since there is no restriction, the direction of these gaps is uncertain. When not forging, the gravity makes the eccentric sleeve 4 sink, and the gap between it and the frame 1 is at the...

Abstract

The invention relates to the technical field of precision forging machines and provides a buffering mechanism of a locking cylinder of the precision forging machine. The buffering mechanism comprises at least two locking cylinders, and is characterized in that one end of an eccentric sleeve is fixedly arranged at a rotary center O2 of a rack of the precision forging machine; a slide block is fixedly connected with the other end of the eccentric sleeve through a pull rod; the two locking cylinders are symmetrically arranged at the two sides of the eccentric sleeve; cylinder body ends of the locking cylinders are hinged and fixed with the rack; and cylinder rod ends are symmetrically fixed with the two sides of the eccentric sleeve through pin shafts. According to the buffering mechanism disclosed by the invention, a gap between the eccentric sleeve and the rack is located at one end of a hammer head at an inclined lower side; and meanwhile, the gap between each two parts is located at the position which is far away from a forging center all the time.

Description

technical field [0001] The invention relates to the technical field of precision forging machines, and relates to a locking cylinder buffer mechanism for precision forging machines. Background technique [0002] The precision forging machine is a forging machine that realizes the multi-hammer high-frequency precision radial synchronous forging method. During forging, each hammer head is required to move synchronously and high-frequency forging, and its frequency can reach 180~2000 times per minute. [0003] During the forging process of the precision forging machine, there are often gaps with indeterminate directions in each component. These gaps make the parts continuously collide with each other in the cycle of forging and stopping forging, which reduces the service life. At the same time, the position of the hammer during forging is also inconsistent with the position of the hammer during adjustment, which reduces the dimensional accuracy of the product.
