Adjustment steps of wire rub machine

Wire rubbing machineIt is a mechanical equipment specializing in the production of screws. It has many specifications of wire rubbing machines, such as: automatic wire rubbing machines, flat wire rubbing machines, semi-automatic wire rubbing machines, fully automatic wire rubbing machines, high-speed wire rubbing machines, etc. The wire rubbing machines are bulky, sensitive, efficient, and have advantages that other similar equipment cannot replace. It prevents the limitations of lathes, drilling machines or manual taps, saves time and effort, is not easy to rot, and the tap is not easy to break. Wire rubbing machines are suitable for all mechanical manufacturing industries, machine tools, molds (factories) machinery, plastic machinery, printing machinery, packaging machinery manufacturing plants, engineering machinery, automobile and motorcycle parts Parts, aviation initiators, rolling stocks, tobacco machinery and general machinery industries. Which type of wire rolling machine to choose? You can choose the type of machine according to the specifications, materials, strength, hardness, product accuracy and local size of threads. The wire rolling machine is mainly composed of a lower body machine, an upper body machine, a transmission mechanism, a feeding mechanism, a cooling pump, an electrical box, etc. During work, the main motor drives the large pulley, and the large pulley drives the main shaft with an eccentric shaft, and the eccentric shaft drives the slider to reciprocate. The following briefly explains the adjustment steps of the wire rolling machine:

(1) Local adjustment of transmission

The main motor pulley of the wire rub machine has two levels of speed. When speed adjustment is required, you only need to turn the handwheel through the bevel gear pair to drive the lifting screw, so that the screw is in a loose or tight state. When you want to adjust the sliding position or the length of the connecting rod, loosen the two tightening nuts of the adjustment screw sleeve to adjust the length of the connecting rod.

(2) Adjustment of feeding mechanism of wire rub machine

The uppermost part of the feeding mechanism is a hopper. Generally, the hopper does not need to be adjusted when it is running smoothly. Driven by the rotation of the roller, the blank is arranged along the material path and slides downward in sequence by gravity. When changing the specifications, you only need to adjust the width of the material path according to different specifications.

(3) Device and adjustment of wire rubbing board

Due to the high manufacturing accuracy standards, when the new equipment is purchased, you only need to place the wire rubbing plate in the fixed wire rubbing groove and the moving wire rubbing groove. After tightening, you can rub fine and qualified products. There is no need to cushion any iron or paper thin objects on the bottom of the wire rubbing plate. Just adjust the gap between the upper ends of the two wire rubbing plates, and then tighten it to start the wire rubbing work.

However, due to manufacturing errors and assembly errors in the wire rubbing machines manufactured by many enterprises, when the wire rubbing plate is installed, it is not necessary to rub qualified products without adjustment. The gap at the upper end of the wire rubbing plate should be adjusted until the blank just enters, but the gap should not be too wide, otherwise the blank will fall off, but it cannot be adjusted too tightly, and the wire rubbing will fall off even if the blank cannot enter. Adjusting the gap between the upper and lower ends is done by rotating two tightening screws and the middle tensioning screw. The gap near the end of the wire rubbing must be relatively small, but the products rubbed must be qualified.

(4) Adjustment of the guide rail surface of the wire rub machine

When the wire rub machine is used for a long time, the surface of the machine guide rail will wear out, and the two wire plates will be uneven up and down, which will present waste. When this situation occurs, two methods can be taken to treat it. One is to scrape the machine and also put on a metal gasket to deal with it. However, padding the metal gasket is not a long-lasting solution, which will cause trouble for adjustment. If you want to deal with it thoroughly, you must scrape it.

(5) Adjustment of the smooth system of the wire rub machine

The smooth system of the wire rub machine is divided into two aspects: smooth transmission and smooth operation. The transmission system should be cleaned regularly and added gear oil, rail oil, hydraulic oil, etc. to ensure the smooth operation of the equipment and reduce process errors. The operation part generally uses special tapping oil to reduce the direct contact between the wire rub machine and the workpiece, thereby reducing equipment losses and reducing the production costs of the enterprise.
