Two working modes and operation of large Thread rolling machine

We all know that large Thread rolling machine is a kind of multifunctional cold extrusion molding machine. Within the range of its rolling pressure, it can roll the workpiece in cold state for threading, straight thread, oblique rolling processing. When we change the working position of the selector switch, you can choose the automatic rolling and pedal mode rolling and manual mode, I'll introduce you to the two working modes of the large Thread rolling machine.

1, automatic cycle mode: start the hydraulic motor, the selector switch to the automatic position, according to the size of the hydraulic pressure to adjust the automatic rolling time and backstop time, respectively. At this time, the sliding seat is under the hydraulic pressure controlled by the forward time relay. , the sliding seat in the backstop time relay under the control of the backstop movement.

2, foot pedal cycle mode: insert the foot pedal line connector, the time relay stops working, step on the switch with your foot, the sliding seat moves forward under the hydraulic pressure, lift your foot after the work rolling is completed, the sliding seat will be retracted under the hydraulic pressure.

Let's take a look at the precautions when operating a large Thread rolling machine.

1, when installing large Thread rolling machine wire roller, should be wiped clean at the root of the roller bar. When loading and unloading the wire roller, first remove the wheel rod support seat respectively, install the wire roller on the wheel rod, and adjust the wire roller to the desired axial position with the adjustment washer. The end faces of the two wire rollers should be adjusted to the horizontal plane as far as possible. The bearings of the wire roller and the support block are combined with washers to prevent axial movement of the wire roller.

2、Support block is mounted on the support seat, and the top of the large wire roller is welded with carbide. Loosen the fastening bolts of the support block, add or subtract shims at the bottom of the support block to adjust the height of the support block, and then tighten the bolts. The height of the support block plays an important role in the rolling compression process.

3, the width of the support block should be subject to the rolling wheel will not collide with the support block. For workpieces with diameters below M10, the width should be close to the allowable width. For workpieces with diameters above M10, the large Thread rolling machine allows the width of the top of the support block to be larger, but it does not have to exceed 18mm.

Large Thread rolling machine is mainly used for upsetting ribbed steel bars in construction works, which is the key equipment for realizing steel bar connection. It is used for steel bar connection works to ensure the quality of connection. Its function is to extrude the head of the threaded steel bar for construction to the pier thickness, so as to increase the diameter of the head of the steel bar and increase the tensile strength. The machine is easy to operate, fast and with high processing quality. It is mainly used in major projects such as construction, roads and bridges, high-speed railroads, subways, tunnels and demanding power stations. Large Thread rolling machine has no pollution, no open flame characteristics, can be processed at any time and anywhere, shortening the construction period, urgent.

The above is my introduction to the two types of large Thread rolling machine operation and operation items. If you still do not understand, please contact us, we will provide you with more information.
