Straightening machine working program

TIME: 2021-09-10

This straightening machine has the characteristics of reasonable structure, convenient operation, safety and reliability, and is suitable for straightening chicken cages, rabbit cages, building mesh pieces, various welding wires, Shule board wire cutting and irregular mesh wires.
The structure of the machine is to adjust the angle of the straight wire mold by rotating the high-speed rotor to achieve the effect of straightening, and then feed the wire forward through the feeding wheel.
After reaching the required size, the thread touches the positioning key and pushes the runway forward by 5 millimeters. The upper punch presses the vertical wire cutter and immediately cuts it. The thread passes through the pressure plate on the vertical wire cutter and presses the open bearing. The thread automatically falls into the support frame. If you want to change the length, move it
Positioning key.
The motivation increases speed through belt transmission, causing the straightening cylinder to rotate at high speed. The steel bars passing through the straightening cylinder are straightened, and the straightening mold is used to remove rust on the surface of the steel bars;
The electric motor drives the hammer head up and down through another pair of reduction belts and a gear reducer, on one hand driving two conveying rollers to move the steel bars forward, and on the other hand driving the crank wheel. When the steel bars are adjusted to the predetermined length, the hammer and fork are placed on the knife holder, and the
Steel bar cutting: When the cut steel bar falls into the receiving frame, due to the action of the spring, the knife almost returns to its original position, completing a cycle.

Performance structure:
Straightening mechanism-
-Consisting of straightening rollers, straightening pressure blocks, and bearing seats at both ends, it completes the straightening work of the wire. Its power is the electric motor installed at the bottom of the frame, which drives the straightening shaft to rotate at high speed through a triangular belt.

Feed mechanism-
-The pressure wheel part is composed of two synchronously running pressure wheels, which are driven by a V-belt chain to drive a pair of gear pairs, and their coaxial pair of pressure wheels operate synchronously.
During work, the metal wire runs forward through the groove on the outer circle of the pressure roller under the action of friction, and adjusting the pressure roller spring can change the wire feed speed. Its maximum value is equal to the outer circular velocity of the pressure roller.
In work, the pressure excitation should be adjusted appropriately based on the diameter and rigidity of the processed wire to achieve the best straightening effect and production efficiency. The cutting mechanism is composed of an eccentric mechanism and a tool holder at one end of the straight thread to jointly complete the cutting action.

The eccentric mechanism is composed of a spindle, a slider, an eccentric wheel, a rocker arm, and a punch, which is assisted by a cutting motor and driven by a V-belt to rotate the spindle. Under the action of the eccentric mechanism, the punch moves back and forth.

When working, when the metal wire in the straight wire groove reaches a fixed length, the metal wire quickly pushes the straight wire groove forward under the frictional force of the pressing wheel group. The protrusion at the back of the punch block at the top of the cutting head moves to the working stroke of the punch, and at this time, it is punched through the punch block

Cut the head to cut the metal wire of a fixed length.

At the same time, when the punch block goes down, it presses down on the slot sealing torsion iron, causing the sealing rod to rotate around the guide rod, detaching the cut wire in the slot, and automatically falling into the wire bucket under action. When the punch block goes up, the blade also goes up. Under the action of the torsion spring, the sealing rod

Reseal the cable tray. After the wire thrust disappears, the straight wire groove returns to its initial state under the action of the tension spring and enters the next cycle.

Wire dropping mechanism-

The material support frame is composed of a cyclone, a material blocking rod, a spindle, a base, etc. The wire reel can rotate around the spindle. After placing the disc-shaped wire, the cyclone can continuously and automatically feed under the pull of the feed mechanism.
