The operating principle of straightening and cutting machine

Aug 19, 2019

1. Performance structure: Straightening mechanism - consists of straightening roller, straightening press block, and bearing housings at both ends to complete the straightening of the wire. The power is the motor mounted on the lower part of the frame, and the straight shaft is rotated by the V-belt at a high speed. Feeding mechanism—The pressure roller part consists of two synchronously running pressure rollers. It is driven by a V-belt chain to drive a pair of gear pairs, and the coaxial pair of pressure rollers are synchronized. During operation, the metal wire runs forward through the wire groove of the outer circumference of the pressure roller under the action of frictional force, and the adjustment of the pressure roller spring can change the feed speed of the wire. Its maximum value is equal to the outer round speed of the pressure roller. In the 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 of the Ruihe straightening and cutting machine. 2. Cutting mechanism—The cutting mechanism is completed by an eccentric mechanism and a tool holder at one end of the straight wire path. The eccentric mechanism is composed of a main shaft, a slider, an eccentric wheel, a rocker arm, and a punch. The power is rotated by the cutting motor through the V-belt drive, and the punch reciprocates up and down under the action of the eccentric mechanism. During operation, when the wire in the straight wire channel reaches a fixed length, the wire quickly pushes the straight wire groove under the friction of the pressure roller group, and the boss at the back of the punch block at the top of the cutter head Move to the working stroke of the punch, at this time, the punching block is impacted by the punching block, thereby cutting the metal wire with a fixed length. At the same time, when the punch block descends, the slotted twisted iron is pressed underneath, and the sealing rod is rotated around the guide rod, and the wire cut in the wire slot is disengaged, and automatically falls into the wire bucket under the action of gravity. When the head is up, the cutter head also goes up. Under the action of the torsion spring, the sealing rod re-closes the trunking. After the linear wire thrust disappears, the initial state is restored by the tension spring and the next cycle is entered. The dropping mechanism—the receiving frame is composed of a cyclone, a blocking rod, a mandrel, a base, etc. The reel can be rotated around the mandrel. After the disc wire is placed, the cyclone can be continuously and automatically given by the feeding mechanism. material.
