Combined guide roller structure of perforating machine

Abstract

The invention belongs to the technical field of punchers, and discloses a combined guide roller structure of a perforating machine, wherein the combined guide roller structure comprises a base; a fixing frame is fixedly mounted at the top of the base, a guide roller body is movably mounted in the fixing frame, bearings are fixedly mounted on the two sides of the fixing frame, rotating shafts are fixedly mounted at the two ends of the guide roller body, and the other end of the rotating shaft sequentially penetrates through the fixing frame and the bearings, extends out of the bearings and is fixedly provided with a flange. By arranging limiting blocks, rigid springs and a limiting arc blocks, due to the fact that the rigid springs are in a compressed state, elastic force can be applied to sleeve blocks, at the moment, the inner sides of the four limiting blocks can be tightly attached to the outer surface of the guide roller body, and the guide roller body rotates more stably; and meanwhile, the limiting arc block is designed, and the limiting effect on the guide roller body is enhanced, and the rotating stability of the guide roller body is further improved.

Description

technical field [0001] The invention belongs to the technical field of piercing machines, in particular to a combined guide roller structure for piercing machines. Background technique [0002] EDM piercing machine refers to the EDM machine tool that uses the principle of EDM to process holes with a size less than five millimeters. It is used to process small and medium-sized dies. Its processing characteristics are not limited by the hardness of metal materials. The template can be quenched first and then used This machine processes the required pass to ensure the quality and improve the service life. [0003] At present, operators often need to use piercing machines when processing parts, and piercing machines are generally equipped with corresponding guide roller structures. However, the stability of the existing piercing machine guide rollers during long-term use Poor, it is easy to shake, which will affect the operation of the operator. At the same time, the guide roll...
