A double-wire palm-joint steel bar straightening mechanism and a double-wire palm-close steel 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-wire palm-closed steel bar straightening mechanism and a double-wire palm-closed steel bar straightening machine adopting the double-wire palm-closed steel bar straightening mechanism. Background technique [0002] At present, the steel bars used in construction projects are usually first cut by straightening and cutting the disc-shaped steel bars produced by the steel factory, and then bent into the required shape before they can be used. The current common straightening methods are: 1), use horizontal and vertical pressure rollers to straighten the steel bars, this method cannot effectively straighten the universally 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", and the rollers in the rotating frame can be used to effecti...

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.
