Efficient brake for press machine

Abstract

The invention discloses an efficient brake for a press machine. The efficient brake comprises a load shaft, a brake wheel, a magnet installation ring, a permanent magnet, a sleeve, a baffle and a connecting bolt. The efficient brake is characterized in that the brake wheel is arranged on the load shaft, a first bearing and a second bearing are arranged between the brake wheel and the load shaft, the magnet installation ring is connected with the brake wheel through a connecting column, and the magnet installation ring is provided with an installation block and a connecting block; the permanent magnet is arranged on the magnet installation ring, the sleeve is connected with the installation block through a connecting column, and a guide column is arranged on the sleeve; and the baffle penetrates the guide column, and the connecting bolt penetrates the baffle to be connected with the sleeve. According to the efficient brake, a first spacer bush and a second spacer bush are arranged between the first bearing and the second bearing which are arranged between the brake wheel and the load shaft, the span between the first bearing and the second bearing is increased through the first spacer bush and the second spacer bush, the bearing capacity of the brake wheel and the rotation accuracy of the brake are improved, and the working efficiency of the brake is improved.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a high-efficiency brake for presses. Background technique [0002] With the development of forging technology and the requirements of stamping production, the working speed of the press is getting higher and higher. With the increase of the working speed of the press, the requirements for the brakes used in the press are also getting higher and higher. The existing brakes have low bearing capacity of the brake wheel, low rotation accuracy of the brake, and the vibration generated by the sudden braking of the press and other equipment is easy to cause damage to the brake, which reduces the quality and performance of the brake and shortens the service life of the brake. As a result, the working efficiency of the press is not high. Contents of the invention [0003] The purpose of the present invention is to provide a brake wheel with long service life and short service life for...
