A method and device for high-speed soft transmission and variable pitch handover of bar material

Abstract

The invention discloses a high-speed gentle conveying and variable-pitch transferring method and device for bars. The high-speed gentle conveying and variable-pitch transferring device comprises a first wheel body, a second wheel body, an axial conveying mechanism and a radial variable-pitch receiving mechanism. The axial conveying mechanism can convey one set of bars onto the radial variable-pitch receiving mechanism, the axial conveying mechanism comprises a conveying arm which is provided with a suction groove block, and the conveying arm can rotate at a preset angle. The radial variable-pitch receiving mechanism comprises movable suction groove swing arms, each set of movable suction groove swing arms comprises a plurality of movable suction grooves, and each movable suction groove swing arm rotates at the preset angle so that the movable suction grooves can receive the bars conveniently. A fixed radial disc cam and a fixed axial cylindrical cam are fixedly installed in the second wheel body. A fixed disc cam is fixedly installed in the first wheel body. The high-speed gentle conveying and variable-pitch transferring device can accurately complete smooth and gentle conveying and variable-pitch transferring of the bars under a high-speed working condition, and greatly reduce the empty-head rate and the external damage rate of the damageable bars.

Description

technical field [0001] The invention relates to a mechanism for changing the direction of bar material transmission during the processing and transmission of bar-shaped articles, and realizing the transfer of bar material with variable pitch between the upstream machine and the downstream machine, including a high-speed soft transmission of bar material and variable pitch A handover method and a device for realizing the method. Background technique [0002] In a typical bar axial-radial transfer and transfer device, the axial braking and radial acceleration of the bar transfer process occur successively. During the high-speed transfer process, the speed and direction of the bar movement change sharply. The material at the end is easy to be thrown out or the surface is scratched, which affects the quality of the product and limits the improvement of the processing efficiency of the vulnerable bar. [0003] There are mainly two types of existing bar high-speed flexible transf...
