Double-line palm closing type reinforcement bar straightening mechanism and double-line palm closing type reinforcement bar straightening machine

Abstract

The invention discloses a double-line palm closing type reinforcement bar straightening mechanism which comprises a fixed bracket consisting of four palm block sliding seats. Palm pressing blocks are arranged among the palm block sliding seats; each palm pressing block comprises a double-line connected fixed palm block, a double-line connected movable palm block and single-line movable palm blocks; separation check blocks are arranged on the upper surfaces of the double-line connected fixed palm blocks; two parallel reinforcement bars respectively pass through both sides of the separation check blocks of the double-line connected fixed palm block; each double-line connected movable palm block and the corresponding single-line movable palm block respectively encircle the reinforcement bars from the upper part and both left and right sides; palm pressing block driving devices for driving the double-line connected movable palm blocks and the single-line movable palm blocks to encircle and be separated are respectively arranged on the double-line connected movable palm blocks and the single-line movable palm blocks. The double-line palm closing type reinforcement bar straightening mechanism disclosed by the invention can extrude and strengthen two reinforcement bars in a time and the efficiency is doubled; meanwhile, due to adoption of an intermittent extruding mode for strengthening the reinforcement bars, the strengthening process is rapid and effective and no frictional loss exists. The invention also provides a novel double-line palm closing type reinforcement bar straightening machine adopting the double-line palm closing type reinforcement bar straightening mechanism.

Description

Technical field [0001] The invention relates to the field of steel bar processing, in particular to a double-line palm-fitting steel bar straightening mechanism, and a novel double-line palm-fitting steel bar straightening machine adopting the double-line palm-fitting steel bar straightening mechanism. Background technique [0002] At present, the steel bar components used in construction projects usually first cut the disc-shaped steel bars produced by the steel mill through straightening, and then bend them into the required shape before they can be applied. The current common straightening methods are: 1) Use horizontal and vertical pressing wheels to straighten the steel bars, this method cannot effectively straighten the universal twisted steel bars; 2) Use the rotating frame to set the rollers to straighten the steel bars This method is disclosed in the patent document "CN200520102272.9-Straightening Roller Device". The rollers in the rotating frame can be used to effective...

Problems solved by technology

However, the step-by-step palm pressure automatic steel bar straightening machine disclosed in this patent has defects in the step-by-step feeding method, and its overall structure and action are still not perfect, and there are many places to be improved.

In addition, the above-mentioned step-by-step automatic steel bar straightening machine can only press and straighten one steel bar at a time, and the efficiency needs to be improved.
