Straightening machine is also called straight wire machine, straightening broken wire machine, straightening cutting machine and cutting machine. It is a kind of straightening equipment. Straightening machine is one of the rebar processing machines. For straightening and cutting of steel bars with a diameter of 14 mm or less, the cut length can be customized according to customer requirements. Adjustable straight cut stainless steel wire, aluminum wire, cold drawn wire, plastic coated steel wire, etc., incision Qi, small error, good performance.

Straightening and cutting machine operating principle: The motor increases the speed through the belt drive, so that the straightening cylinder rotates at high speed, the steel bar passing through the straightening cylinder is straightened, and the straightening die removes the scale surface of the steel bar; the motor passes another pair of deceleration belts. Drive and gear reducer, on the one hand to drive two transmission roller, traction steel forward movement, on the other hand to drive the crank wheel, the hammer up and down movement. When the steel bar is adjusted to a predetermined length, the hammer strikes the upper blade holder, the steel bar is cut off, and the severed steel bar falls into the receiving frame. Due to the action of the spring, the blade table returns to its original position and completes a cycle. 1. Performance structure: Straightening mechanism - consists of straightening rollers, straightening press blocks, and bearing seats at both ends to complete straightening of the wire. Its power is installed in the lower part of the chassis of the motor, through the V-belt to drive the high-speed rotation of the straightening shaft. Feed mechanism - the pressure wheel part is composed of two synchronously operated pressure rollers. Through the triangle belt chain drive, a pair of gear pairs are driven, and a pair of coaxial pressure wheels are synchronously operated. During work, the metal wire runs forward through the slot of the outer circle of the pressure roller under the action of friction. Adjusting the spring of the pressure roller can change the feeding speed of the wire. The maximum value is equal to the outer circle speed of the pressure roller. During work, the pressure should be properly adjusted according to the diameter and rigidity of the processed wire to obtain the best straightening effect and production efficiency. Shut-off mechanism - The shut-off mechanism consists of an eccentric mechanism and a knife holder at one end of the straight thread path to complete the cutting action. The eccentric mechanism is composed of a main shaft, a slide block, an eccentric wheel, a rocker arm, and a punch. The power is driven by a cut-off motor through a V-belt drive to rotate the main shaft. Under the action of the eccentric mechanism, the punch head is reciprocated up and down. When working, when the wire in the straight wire channel reaches a fixed length, the wire is quickly pushed forward by the wire slot under the action of the friction force of the press wheel set. The punch on the back of the punch press block at the top of the cutter head It moves to the working stroke of the punch. At this time, the punch presses the knife head to cut the metal wire in fixed length. At the same time, when the punch block descends, the groove seals the twisted iron under the groove, so that the sealing wire rod rotates around the guide rod, and the disconnected wire material in the wire groove is automatically dropped into the wire barrel under the action of gravity. When the head is lifted, the cutter head also goes up. Under the action of the torsion spring, the sealing rod re-seals the wire trough. After the straight wire groove disappears from the wire, it resumes its initial state under the tension spring and enters the next cycle. Dropping mechanism——The receiving frame consists of cyclone, stopper, spindle, base, etc. The reel can be rotated around the mandrel. After placing the disc-shaped wire, the tornado can be continuously and automatically given by the feeding mechanism. material.
