Thread rubbing machine is specialized in the production of screw machinery and equipment, there are many specifications of thread rubbing machine, such as: automatic thread rubbing machine, plate thread rubbing machine, semi-automatic thread rubbing machine, automatic thread rubbing machine, high-speed thread rubbing machine. The twisting machine is heavy, sensitive, efficient and has the advantages that other similar equipment can not be replaced. It prevents the limitations of lathe, drilling machine or manual tapping, saves time and effort, is not easy to break teeth, tap is not easy to break, etc. Thread rubbing machine is suitable for all machinery manufacturing industries, machine tool, mould (factory) machinery, plastic machinery, printing machinery, packaging machinery manufacturers, construction machinery, automobile and motorcycle parts, aviation engine, locomotive and rolling stock, tobacco machinery and general machinery and other industries. Choose what kind of rolling machine, according to the product specifications, material, strength, hardness and product accuracy and thread local size, the resolution to choose the type of machine. The thread rubbing machine is mainly composed of lower body machine, upper body machine, transmission mechanism, feeding mechanism, cooling pump, electrical box and so on. When working, the main motor drives the big belt wheel, the big belt wheel drives the spindle with the eccentric shaft disc, and the eccentric shaft drives the slider to reciprocate through the connecting rod. The following is a simple description of the adjustment steps of the thread rubbing machine:

(1) Local adjustment of transmission

The main motor of the screw rubbing machine has two stages: fast and slow. When the speed is required, the hand wheel is driven by the bevel gear pair to lift the screw, so that the screw is in a loose or tight state. When you want to adjust the position of the slider or the length of the connecting rod, loosen the two fastening nuts of the adjusting screw sleeve to adjust the length of the connecting rod.

(2) the adjustment of the feeding mechanism of the thread rubbing machine

The top part of the feeding mechanism is the hopper, the hopper is generally stable operation without adjustment. The billet is driven by the rolling wheel, so that the billet is uniformly arranged along the material channel and slides downward by gravity. When changing specifications, just adjust the width of the material channel according to different specifications.

(3) The device and adjustment of the thread rubbing board

Because of the high manufacturing precision standard, when the new equipment is purchased and just used, just put the rubbing wire plate in the fixed wire plate slot and the moving wire plate slot, and then the fine qualified products can be rubbed out after fastening. The bottom surface of the rubbing wire plate is not padded with any iron or paper thin material. Just adjust the gap between the upper end of the two wire plate, and then tighten the thread can start to work.

But many enterprises manufactured by the rubbing machine due to the existence of manufacturing error and assembly error, when the device after the rubbing plate, without adjustment may not be able to rub qualified products. The clearance of the upper end of the rubbing silk plate should be adjusted to the blank just into, but the clearance should not be too wide, otherwise the blank will fall down, but also can not be adjusted too tight, the blank into the silk plate will fall down. The adjustment of the upper and lower end clearance is accomplished by rotating the two set screws and the middle tension screw. The clearance near the end of the wire plate should be relatively small, but the product must be qualified.

(4) adjust the guide rail surface of the thread rubbing machine

When the rubbing machine is used for a long time, the guide rail surface of the machine will wear, and the two silk plates will be uneven up and down, which will present waste. In this situation, two methods can be adopted to deal with it. One is to shovel the machine and pad the metal gasket to deal with it. But the pad metal sheet is not a lasting measure, which will bring trouble to the adjustment, to be thoroughly treated must also be shoveled.

(5) adjustment of the smooth system of the thread rubbing machine

The smooth system of the thread rubbing machine is divided into two aspects: smooth transmission and smooth operation. The transmission system should be regularly cleaned and added gear oil, guide oil, hydraulic oil, etc., to ensure the smooth operation of the equipment and reduce the error of the process; The operation part generally uses special tapping oil to reduce the direct contact between the thread rubbing machine and the workpiece, so as to reduce the loss of the equipment and reduce the production cost of the enterprise.
