Full-automatic groove breaking necking machine

Abstract

The invention discloses a full-automatic groove breaking necking machine. The full-automatic groove breaking necking machine structurally comprises a groove breaking necking pressing cylinder, a beamshrinking groove, a carrying lifting table, an electromagnetic valve seat, a relay, an electric control box and a transmission case. According to the full-automatic groove breaking necking machine, the groove breaking necking pressing cylinder is matched with the beam shrinking groove, so that a rotary threaded groove cleaning effect is formed, and steel fragments splashed during stamping neckingform a surrounding collection guide effect; a frame connecting rod forms a gradient type combined winding brush effect, so that impurities penetrating through the surface can be conveniently cleaned in the equipment stamping process, and the size precision of a pipe opening assembled in the later period can be conveniently adjusted; then a pipe opening fine adjustment frame is used for forming anannular frame longitudinal alignment correction effect on the stamping pipe opening, so that the longitudinal line distance and a rotary sliding brush form a combined linkage multi-axis motion effectthrough a bevel gear supporting frame, the stress point of a knife rest during groove breaking is improved, and a rotary unloading machining effect is formed; and the groove breaking sliding inertia is assisted to be pushed, so that the quality of a scaffold steel pipe machined by the whole groove breaking locking opening is improved.

Description

technical field [0001] The invention is a fully automatic slotting and shrinking machine, which belongs to the field of automatic machinery. Background technique [0002] Fully automated mechanical equipment is an intelligent equipment that saves labor and forms a complete set of assembly line processing by independent programming. In the processing of steel pipes for scaffolding, it is necessary to use automated machinery to break grooves and insert and assemble pipes, and the shrinkage of pipes is also convenient for scaffolding. The key is to let the entire scaffolding process pipes form an automatic batch finishing effect. The shortcomings of the current technology to be optimized are: [0003] During the assembly process of the nozzle shrinkage and broken groove of the scaffold steel pipe, the cracks on the surface of the steel pipe will be aggravated due to the compressed groove of the debris steel sheet, which will cause the bracket crack to extend and break during th...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a fully automatic slotting and shrinking machine to solve the problem that the scrap steel sheet cushion compresses the slot during the assembly process of the nozzle shrinkage of the scaffold steel pipe. As a result, the cracks on the surface of the steel pipe will be aggravated, and the scaffolding pipe after shrinking will be extended and broken during the assembly process. As a result, due to the accumulation of impurities and the excessive punching density of the shrinking machine, the processed materials will be scrapped and affect the later stage. The construction is progressing, and the broken notch is in the secondary molding and cladding, steel fragments will be mixed in the nozzle end, causing the surface of the fitted pipe to be twisted, and the internal gap will be thickened, causing the pipe body of the scaffold to be inserted too tightly, and other pipes will be overturned. The edge of the mouth, causing the problem of pipe curling
