The thread is smooth and standard, the machine tool is easy to operate, the work is reliable, the rolling specification is adjustable, the cutting head has an automatic long knife and a take-up device, which is flexible and reliable, and can realize the automatic shutdown of the wire head length according to the specifications. The hand-clicked reversing button reverses away from the workpiece, and the time difference of the hand-to-hand reversing button is used to achieve a delay effect, and it can automatically stop when it is shaken to the 0 position.

The internal cutting lubricating fluid device is adopted, and the cooling and lubrication effect is better. Processing a specification of steel bar, only need to pick a machine tool, start a switch, can continuously process a large number of wire heads, the operation procedure is greatly simplified, overcome the general screw machine tool operation steps repetitive, cumbersome drawbacks, reduce labor intensity, greatly improve work efficiency. The machine tool is equipped with a leakage protector to effectively ensure personal safety.

The straight thread connection of steel bar rolling is a special rolling machine tool to roll the end of the steel bar, and the thread is formed at one time. The rebar is rolled into the thread, and the material at the bottom of the thread is not cut off, but is squeezed out, increasing the original diameter.

Accessories: thread thread head through stop ring gauge, length gauge, etc. The thread rolling machine is to use cutting and rolling threads to form at one time to noise the purpose of strengthening and threading the end of the steel bar, which solves the problem of pretreatment of the end of the steel bar before processing, and the problem that the same equipment needs to be rolled many times, so that the process processing and multiple steel bar handling are reduced on site, and the on-site production and processing efficiency is improved; The thread rolling machine can realize the rolling processing of a variety of specifications of steel bars by using a thread rolling head, which solves the situation that similar equipment needs one thread rolling head of each specification for processing straight threads at the end of steel bars. The thread rolling machine adopts internal coolant, which solves the problem of chip removal during rolling processing, has high automation strength, and automatically stops the feed and resets.

The steel bar stripping straight thread rolling machine is a special equipment for processing the straight thread head of the steel bar, the end of the steel bar is rounded through the rib stripping knife, and then the steel bar is rolled with three hollow thread rolling wheels, so as to meet the quality requirements of the straight thread forming of the steel bar. The ribbed steel bar straight thread connection joint meets the requirements of the A-level connection standard required by JGJI07-2003 "General Technical Regulations for Mechanical Connection of Steel Bars". The thread rolling machine is added with 16-40mm nine specifications of steel bars in GB1499-1998 "Hot Rolled Ribbed Steel Bars for Reinforced Concrete".

Steel bar straight thread rolling machine is a kind of steel bar processing machinery that has been widely used in the construction industry in recent years. It rolls the end of the steel bar quickly and directly at one time to produce cold hardening of the wire head, so that the strength is improved, and the steel bar head is the same as the base metal. It is composed of a frame, a clamping mechanism, a feed carriage, a reducer and a thread rolling head, a cooling system and an electrical system.

The straight thread stripping and rolling machine of the steel bar feeds the end of the steel bar into stripping and rolling at one time. It is easy to operate, reliable in quality, and can be shut down and reversed according to the adjusted diameter and length. This machine adopts an internal water outlet structure, which has better cooling and lubrication effect.

Processing a certain specification of steel bar can be continuously processed as long as the equipment is adjusted.

No, it's the equivalent of a lathe.
