Semi-automatic preparation equipment of short square tube boss for square tube frame of medical science popularization bulletin board

Abstract

The invention belongs to the technical field of science popularization bulletin board manufacturing equipment, and relates to semi-automatic preparation equipment of a short square tube boss for a square tube frame of a medical science popularization bulletin board. A servo motor drives the combination of a conveying clamp assembly and a square tube base material to be pushed forwards along the linear guide rail through a ball screw pair. Corner supporting blocks and side supporting blocks support the inner corners and the inner faces of the square tube base material. The first combination ofthe corner supporting blocks and the pistons, the second combination of the side supporting blocks and the pistons and a front bending movable cutter form a front bending die to complete front bending. Four rhombic square holes are punched by a punching hydraulic cylinder punching movable cutter, the front vertex and the rear vertex of each rhombic square hole are located on the edge of the squaretube base material and the other two vertexes are located on two planes adjacent to the edge respectively. A shearing and post-bending hydraulic cylinder is started and a shearing and post-bending movable cutter carries out cutting and post-bending in sequence. Manual manufacturing is changed into mechanical automatic manufacturing, the working efficiency is improved, the labor intensity is reduced, the labor safety is improved, the appearance quality is improved and the size accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing equipment for popular science bulletin boards, and relates to manufacturing equipment for components used in popular science bulletin boards for medical science. Background technique [0002] The main frame of the medical science popularization bulletin board is a square tube, including two upright square tubes and two horizontal square tubes. Welding, the middle part of the upright square tube is welded to the two ends of the second horizontal square tube respectively, the area surrounded by the two upright square tubes and the two horizontal square tubes is used to set the display board and the transparent glass door, and the display board is pasted to display medical treatment Popular science poster. Two to three short square tube bosses are often placed side by side on the upright square tube. It is 30 mm, and the wall thickness is very thin, generally no more than 0.6 mm. When the sh...
