Automatic roll shearing device used for machining trapezoidal nail and machining method

Abstract

The invention provides an automatic roll shearing device used for machining a trapezoidal nail. The automatic roll shearing device comprises a tool platform of a high-low structure. A vertical plate of the perpendicular platform surface is fixedly connected to the outer side of the low end of the tool platform, and a motor and a reducer are installed on the platform surface of the high end of the tool platform from right to left in a spaced mode. The vertical plate is provided with an upper hole and a lower hole of which the axes are coaxial and parallel to the axis of the reducer. A first transmission shaft is installed in the upper hole. A second transmission shaft is installed in the lower hole. A first transmission gear is installed at the right end of the first transmission shaft through a key, and an upper roller is installed at the left end of the first transmission shaft through a key. A second transmission gear is installed at the right end of the second transmission shaft through a key, and a lower roller is installed at the left end of the second transmission shaft through a key. An output shaft of the motor is connected with the input end of the reducer through a first coupler. The output end of the reducer is connected with the right end of the first transmission shaft through a second coupler. A transmission mechanism is further installed in the position, corresponding to the back side of the tangent of the circumferential surface where the upper roller and the lower roller make contact with each other, of the vertical plate. The automatic roll shearing device used for machining the trapezoidal nail has the advantages of being simple in structure, high in automation degree and material utilization rate and low in production cost and labor intensity of workers.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and relates to a rolling shear device, in particular to an automatic rolling shear device and a processing method for processing trapezoidal nails. Background technique [0002] In modern stamping production, external forces are mainly applied to plates, strips, pipes and profiles by stamping machines and dies. In the whole production process, relying on workers to operate the stamping machine to complete the stamping work, there are often phenomena such as high labor intensity and low material utilization rate. In order to meet the continuous and rapid processing requirements of stamped products, it has become inevitable to develop devices that can realize automatic processing. the trend of. [0003] At this stage, the demand for trapezoidal nails in the project is very large, and the supply is often in short supply. At present, the processing of trapezoidal nails is ma...
