Description

Method for processing steel transverse rib of right-handed anchor rod

Technical Field

The invention relates to a right-handed screw processing technology, in particular to a processing method of a right-handed anchor rod steel transverse rib.

Background

The slitting rolling of steel products is that one large-size blank is rolled into two or more parallel rolled pieces with the same shape by using the function of a hole pattern in the rolling process, and then the rolled pieces are longitudinally slit into two or more single rolled pieces by using slitting equipment or a roll collar of a roll. The splitting rolling generally includes rough rolling, intermediate rolling, fine rolling and the like, and the stock is gradually rolled into parallel rolled pieces and then split. The splitting rolling technology is applied, but is used in the production of ribbed steel bar or angle steel, and the ribbed steel bar has required size and has no requirement on the alignment of transverse ribs. In order to ensure that the right-handed anchor rod steel bar can be smoothly sleeved with the nut in the using process, a single-line rolling method is adopted for production in the production process, and the single-line production capacity is influenced due to the influence of the equipment capacity.

In particular, the split-rolled right-hand bolts require the use of a roll with a plurality of grooves with transverse ribs. For a long time, the processing procedures of the bar and wire roller groove rolling and the transverse rib are as follows: and after the first rolling groove is milled, the cutter moves forwards and transversely to the adjacent second rolling groove for secondary processing. Because one milling cutter can mill 3-4 grooves at most, the milling cutter needs to carry out cutter changing operation after being worn, and different milling cutter heads have processing dimension errors, so that the contour dimension of the processed transverse rib has deviation; in addition, in the process of installing the cutter, the height and the low position of the cutter and the length and the short dimension of the cutter bar are changed, so that errors exist in the positioning of the milling initial position of the transverse rib. Therefore, in the prior art, transverse ribs machined in different grooves on the same roller are uneven, arranged differently and have poor precision. Therefore, it is difficult to install the right-handed bolt on the press machine to align the bolt up and down to roll the right-handed bolt.

Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-2, a method for processing a steel transverse rib of a right-handed bolt comprises a press roll for rolling a steel bar of the right-handed bolt, wherein the press roll is provided with rolling grooves 1 which are annularly arranged, the rolling grooves 1 are internally provided with transverse ribs 2 for rolling and forming convex ribs 3 of the right-handed bolt, a plurality of rolling grooves 1 are arranged on the same roll along the length direction, the transverse ribs 2 of all the rolling grooves 1 on the same roll are neatly arranged on the same horizontal position, the transverse ribs 2 are milled by a machine tool, the machine tool comprises a rotary workbench for arranging a roll to be processed and a milling mechanism provided with a milling cutter for milling and forming the transverse ribs 2, the roll to be processed is arranged on the rotary workbench, and the milling mechanism is matched with the milling and forming transverse ribs 2. The special feature is that the transverse ribs 2 of all the rolling grooves 1 on the same roll are arranged regularly at the same horizontal position, i.e. the transverse ribs of all the rolling grooves need to be consistent in position and shape to meet the requirement of multi-line rolling by partial pressure method.

The method is characterized in that a radial straight line is drawn on the roller body before the transverse rib 2 is milled in the machining process, and the straight line is used as a machining starting line 4 and is used as a tool setting reference. So as to obtain the requirement that the transverse ribs 2 of all the grooves 1 on the same roll are arranged in a same horizontal position in order.
