Abstract

A cold-rolling pipe mill operating frame for rolling a hexagonal pipe comprises a cylindrical sleeve, rollers and a mandrel, wherein the rollers are arranged in the sleeve in a face-to-face manner. The rollers are provided with roller surfaces with appearance similar to that of two optional angle legs of the hexagonal pipe, a rolling channel for a hexagonal pipe billet is formed after the rollers are combined; a roller sliding mechanism is arranged on each roller and comprises a sliding way and a synchronous gear; linear roller ways respectively for each roller to axially slide are arranged on the sliding ways; one end of each sliding way is provided with a rack meshed with the corresponding synchronous gear; and a gear shaft is arranged between each synchronous gear and the corresponding roller. By the aid of a three-roller arrangement structure and the roller ways designed according to special linear design, the rolled hexagonal pipe has a regular body and an accurate size and further production efficiency is higher by ensuring uniformity of the rollers in pure rolling. In addition, the cold-rolling pipe mill operating frame has the advantages of simple structure and convenience in replacement.

Description

A kind of rolling mill of cold-rolling mill for pipes rolling of rolling six square tube materials

Technical field

The utility model relates to a kind of special-purpose rolling equipment, particularly a kind of rolling mill of cold-rolling mill for pipes rolling of rolling six square tube materials.

Background technology

Continuous propelling along with the research and development of rolling equipment design, more parts Jia Gong Lai big in batches, uniformity and low cost, for the comprehensive market competitiveness that promotes product plays a positive role, in recent years, six square tube materials are used widely with the high-strength structure of its hexagonal, research and develop the tubing of not only having the production efficiency height but also can guarantee six square tube quality and press equipment, to become people in the industry's common recognition.

The utility model content

The purpose of this utility model is to provide a kind of overall structure simple, rolls the rolling mill of cold-rolling mill for pipes rolling of the six square tube materials that prolong quality assurance.

The technical solution of the utility model is: a kind of rolling mill of cold-rolling mill for pipes rolling of rolling six square tube materials, comprise cylindrical sleeve, be arranged at the roll and the plug that are Chinese character pin-shaped layout in the sleeve, the roll surface of described roll is provided with and the close roll surface of any two arm of angle profiles of six square tube materials, at each roll and close the rolling passage that the back forms hexagonal pipe pipe, on each roll, be provided with the roll slide mechanism, described roll slide mechanism comprises slideway, synchromesh gear, wherein: on slideway, be provided with and supply the linear in axial sliding roller-way of each roll respectively, end at slideway is provided with the tooth bar that is meshed with synchromesh gear, and above-mentioned synchromesh gear and roll shop building are provided with gear shaft.

The utility model since the roll structure that has adopted three roller layouts in conjunction with by the roller-way of the specific linear design uniformity when guaranteeing that each roll is done pure rolling, not only body is regular not only to make six square tubes that roll out, size is accurate, and production efficiency is higher, in addition, the utility model also has simple in structure, changes advantage easily.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model schematic diagram of movements.

Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment

The utility model such as Fig. 1, shown in Figure 2, a kind of rolling mill of cold-rolling mill for pipes rolling of rolling six square tube materials, comprise cylindrical sleeve 1, be arranged at the roll 3 and the plug 5 that are Chinese character pin-shaped layout in the sleeve 1, the roll surface of described roll 3 is provided with and the close roll surface of any two arm of angle profiles of six square tube materials, at each roll 3 and close the rolling passage that the back forms hexagonal pipe pipe, on each roll, be provided with the roll slide mechanism, described roll slide mechanism comprises slideway 2, synchromesh gear 6, wherein: on slideway 2, be provided with and supply the linear in axial sliding roller-way of each roll respectively, end at slideway 2 is provided with the tooth bar that is meshed with synchromesh gear 6, and above-mentioned synchromesh gear 6 is provided with gear shaft 8 with roll shop building.

Each slideway 2 bottom in sleeve 1 also are equipped with and are adjusted wedge 7.Above-mentioned plug 5 cross sections are hexagon, are provided with at an end of plug 5 and can drive the rotating and swinging device that pipe 4 is done 60 ° of swings.

The rolling mill of cold-rolling mill for pipes rolling of rolling six square tube materials is main body sleeve 1 supports by circular heavy wall, in its inside major parts such as adjusting wedge 7, slideway 2, roll 3 and synchromesh gear 6 is installed successively.

Having three rolls 3 in work housing directly is supported on the set roller-way of the slideway made by the specificity line 2 with its roller and does pure rolling, end at each roll diameter of roller is equipped with synchromesh gear 6 simultaneously, end at slideway 2 is fixed with tooth bar, be meshing with each other by synchromesh gear 6 and tooth bar, guarantee the uniformity of three rolls 3 when doing pure rolling.Under the effect of external force, the roller of roll 3 directly with between the slideway 2 produces relative rolling, and roll 3 rolls forward along the surface of rolling pipe 4 simultaneously.Three rolls 3 are evenly distributed in the sleeve 1 of cylindrical heavy wall, form the hexagon pass.And be placed with hexagon plug 5 in the inside of rolling pipe 4, guaranteeing the interior hole shape of finished product in the operation of rolling, three rolls 3 roll forward synchronously and have just realized rolling to pipe 4.Along with work housing is done periodic reciprocating motion, just realized continuous rolling to pipe 4.When the pipe of rolling different size, roll 3, slideway 2 and the plug 5 that be mentioned above only needing to change get final product.Roll Pass is according to the design of the appearance and size of roll six square tubes, when the outside dimension that shuts out finished product is bigger than normal or less than normal, can move up and down by moving forward and backward adjustment wedge 7 driving slideways 2, so just can adjust, to guarantee to roll out high-precision hexagon production tube the dimensional tolerance of roll six square tubes.
