How to adjust the steel wire of steel bar threading machine

Abstract: How to adjust the size of steel bar threading machine? How long can the steel threading machine usually be sleeved? The threading machine can make the processing of pipe threads simpler and faster during pipeline installation, and reduce the labor intensity of pipeline installation workers. Then let's take a closer look at some problems in the use of the steel threading machine. How to adjust the size of the steel threading machine? How to adjust the wire? How long can the steel threading machine generally cover?

How to adjust the size of steel threading machine

1, according to the diameter of the processed steel bar, replace the steel wire roller suitable for the processing diameter.

2. After the steel wire roller is adapted to the machining diameter, insert the tool setting bar adapted to the steel bar into the center of the rolling head, adjust the steel wire roller to make it contact with the tool setting bar, pull out the tool setting bar, tighten the screw, and press down the gear ring to make it motionless.

3. According to the specifications of the processed steel bars, adjust the position of the rib stripping stroke stop to ensure that the rib stripping length reaches the required value.

4, according to the specifications of the processing steel bar, adjust the position of the press block, to ensure that the effective length of the wire rolling reaches the required value.

How to adjust the steel wire of steel bar threading machine

First, the preparation before processing

1. Connect the power cord and ground wire as required and turn on the power supply. The power supply is a three-phase 380V50Hz AC power supply. To ensure personal safety, please use the automatic switch with leakage protection function.

2. In the coolant tank, add enough soluble coolant (it is forbidden to replenish coolant).

Second, the empty test run

1, turn on the power. Check whether the cooling water pump works normally.

2. Operate the button to check whether the electrical control system works normally.

Third, the workpiece clamping

Install the steel bar to be processed on the centering jaw, and the protruding length should be aligned with the end face of the peeling blade of the rolling head at the initial position, and then pull the handle to clamp.

Fourth, the operation process

1. Turn on the power supply, open the cooling water valve, press the forward rotation start button, turn the feed handle, and feed in the direction of the workpiece to realize cutting. When the rib stripping length meets the requirements, the rib stripping knife will automatically open and rotate the handle to continue feeding, thus realizing wire rolling. When the wire roller contacts the steel bar, it must be stressed and make the spindle rotate once. When the axial feed with pitch length reaches a certain level, it can realize automatic feed until the whole rolling process is completed, and it can realize automatic stop and automatic tool withdrawal.

2. Rotate the feed handle clockwise after automatic tool withdrawal, and return the rolling head to the initial position. At this point, the rib stripper will automatically reset. Just unload the processed workpiece.

3. Check the thread length with ring gauge, and the error is qualified within the range; At the same time, check the size of the thread head with the thread stop gauge. If the gauge can be screwed in, if the stop gauge can't be screwed in or can't be screwed in completely, it is qualified.

4. When reversing rolling, first exchange any two positions of the rolling wheel in the rolling head;

5. When rolling the reverse thread, press the reverse start button, rotate the feed handle, and feed in the direction of the workpiece to realize cutting. When the rib stripping length meets the requirements, the rib stripping knife automatically opens, the rolling head rotates in the opposite direction, and the control handle continues to feed, so that the reverse thread can be rolled. When the wire roller contacts the steel bar, it needs to apply force to make the spindle rotate once, with a pitch length in the axial direction. When it is fed to a certain extent, it can realize automatic operation. Automatic tool withdrawal.

Five, tool regrinding and replacement

1. When the rib stripper cuts a certain number of steel bars, the blade will become dull. At this time, the stripping rib should be removed, and the front edge surface of the tool should be polished to 0.2-0.3mm (it is forbidden to polish the top surface of the blade), which can be reused after installation.

2. When the rib-stripped blade mouth is cracked and cannot be cut normally, a new blade can be replaced.

3. After the silk roller rolls out a certain number of silk heads, if the qualified silk heads cannot be rolled out due to wear and tooth profile damage, a new silk roller should be replaced in time.

How long can the steel threading machine usually be sleeved?

The processing range of 3-inch threading machine (Model 80) is: 1/2"-3 "(inch).

The processing range of 4-inch threading machine (model 100) is:1/2 "-4" (inch).

The processing range of 6-inch threading machine (model 150) is 2 1/2"-6 "(inch).
