Mechanism for shearing steel bar straightening and shearing machine

Abstract

The invention discloses a shearing mechanism for a reinforcing steel adjusting cutter. The mechanism is provided with a dimensioning block and a positioning baffle plate which can limit a shearing pedestal. A reinforcing steel bar to be sheared is precisely cut at the required length each time by a shearing opening which is formed by a fixed cutter body and a movable cutter body in the shearing pedestal, so that the blanking length of the reinforcing steel bar is precise and errorless, and raw materials can be greatly saved; simultaneously, due to arrangement of offsetting pressure springs and lifting rods, the movable cutter body can be guaranteed to stably reset in time, so as to perform next shearing action, the consistency of the shearing motion is guaranteed. The shearing mechanism for the reinforcing steel adjusting cutter has low cost, and can guarantee high-efficiency and continuous operation of the machine; and the length of the sheared reinforcing steel bar is precise.

Description

Technical field: [0001] The invention relates to a shearing mechanism, in particular to a shearing mechanism in a steel bar straightening and cutting machine. Background technique: [0002] There are two types of shearing mechanisms for steel bar straightening and cutting machines currently on the market: one is the gear cutting type, and this mechanism is equipped with a shearing blade on two mutually meshing gears. When the blade is in the corresponding position, cut the straightened steel bar. Because the elimination of the movement consistency of the two shearing gears after cutting the steel bar is controlled by the wheel disc and the brake ring installed at the other end of the gear shaft, and the wheel disc brakes in the inner hole of the brake ring by the friction between the two circumferential surfaces. , after cutting the steel bar each time, the position where the shearing blade stops is not constant. Therefore, the unsolvable defect of this kind of shearing mec...

Problems solved by technology

Because the elimination of the movement consistency of the two shearing gears after cutting the steel bar is controlled by the wheel disc and the brake ring installed at the other end of the gear shaft, and the wheel disc brakes in the inner hole of the brake ring by the friction between the two circumferential surfaces. , after cutting the steel bar each time, the position where the shearing blade stops is not constant. Therefore, the unsolvable defect of this kind of shearing mechanism is that there is always an error of 20-30 (mm) in the cutting length, and the raw material is wasted.

The other is a hydraulic shearing shearing mechanism. The main defect of this mechanism is that it cannot cut steel bars with a length shorter than 500 (mm), and the mechanism will cost 2000-4000 yuan to add hydraulic oil once. Increased cost of use
