Description

Preliminary cold rolling mechanism for cold drawing cross steel

Technical Field

The utility model relates to a cross steel apparatus for producing, the cross steel cold drawing that is arranged in processing scaffold frame system cotter cross steel specifically says so is with preliminary cold rolling mechanism.

Background

The scaffold system is a working platform which is erected for ensuring that each construction process is smoothly carried out, and bayonet cross steel is arranged in the scaffold system. At present, the cross-shaped steel of the clamping pin in the scaffold system is produced into a cross-shaped steel blank in a hot rolling mode, namely a mode that round steel is produced into the cross-shaped steel blank through a hot rolling mill group. However, the hot rolling is a secondary finished product of a raw material of steel rolling, so that more raw materials are consumed, and the environment pollution generated in the hot rolling production process is serious, the surface quality of a product is poor, the dimensional precision is not high, and the strength is low.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a cross steel cold drawing is with preliminary cold rolling mechanism, adopt this mechanism production cross steel can save raw and other materials, do not have environmental pollution to produce, the surface quality of product is better, and size precision and intensity are higher.

In order to solve the problems, the following technical scheme is provided:

the utility model discloses a cross steel cold drawing processing is with preliminary cold rolling mechanism's characteristics are top roll and the bottom roll that sets up side by side including the parallel, the size of top roll and bottom roll, the shape is the same, from its one end to another end on the lateral wall of top roll and bottom roll set gradually not less two shaping annulars, thereby form between top roll and bottom roll and be no less than two shaping holes, the width of shaping annular diminishes gradually from the one end of top roll and bottom roll to another end, the section of that shaping annular that the width is the V-arrangement, the tank bottom of other shaping annulars all is circular-arcly, and equally divide of their lateral wall is two sections, the section of two sections lateral walls is the obtuse angle, the shaping hole shape that the shaping annular that the width is minimum corresponds is the same with the shape of cross steel blank.

The number of the forming ring grooves is four.

By adopting the scheme, the method has the following advantages:

because the utility model discloses a cross steel cold drawing processing is with preliminary cold rolling mechanism includes top roll and bottom roll, from its one end to another end on the lateral wall of top roll and bottom roll set gradually two not few shaping annulars, thereby form between top roll and bottom roll and be no less than two shaping holes, the width of shaping annular diminishes gradually from the one end of top roll and bottom roll to another end, the section of that shaping annular that the width is the V-arrangement, the tank bottom of other shaping annulars all is circular-arcly, and equally divide for two sections of their lateral wall, the section of two sections lateral walls is the obtuse angle, the shaping hole shape that shaping annular that the width is minimum corresponds is the same with the shape of cross steel blank. When the cross-shaped steel blank is in work, the raw material is sequentially rolled from the forming hole corresponding to the forming groove with the largest width to the forming hole corresponding to the forming groove with the smallest width under the normal temperature condition, and then the cross-shaped steel blank is obtained. The processing mode is cold rolling, compared with hot rolling, the processing mode has the advantages that the consumption of raw materials is less, the environment is not polluted, and the surface quality, the precision and the strength of the product are greatly improved.

Drawings

Fig. 1 is a schematic structural diagram of the preliminary cold rolling mechanism for cold drawing cross steel of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a cross steel cold drawing processing is with preliminary cold rolling mechanism including parallel top roll 2 and the bottom roll 1 that sets up side by side, the size of top roll 2 and bottom roll 1, the shape is the same, four shaping annular 3 have set gradually from its one end to the other end on the lateral wall of top roll 2 and bottom roll 1, thereby form between top roll 2 and bottom roll 1 and be no less than two shaping holes 4, the width of shaping annular 3 diminishes gradually from the one end of top roll 2 and bottom roll 1 to the other end, the section of the biggest shaping annular 3 of width is the V-arrangement, the tank bottom of other shaping annular 3 all is circular-arcly, and equally divide of their lateral wall into two sections, the section of two sections lateral walls is the obtuse angle, the shaping hole 4 shape that the smallest shaping annular 3 of width corresponds is the same with the shape of cross steel blank.

When the cross-shaped steel blank is in work, the raw material is sequentially rolled from the forming hole 4 corresponding to the forming groove with the largest width to the forming hole 4 corresponding to the forming groove with the smallest width under the normal temperature condition, and then the cross-shaped steel blank is obtained. The processing mode is cold rolling, pollution is avoided, the used raw materials are few, and the surface quality, the precision and the strength of the product are high.
