Problems solved by technology

Due to the processing equipment, means and manufacturing process in the final overall processing of the reel, the reel can only be expanded to a true round state for finishing in the final processing of the reel.
However, it is impossible to obtain the helix for strip coiling in a simple way. Even if it can be processed into a helix, it can only be a pitch, which cannot meet the coiling needs of strips with different thicknesses.
At present, although some individual coiler reels have been improved, their shape is still based on a true circle, with only a part of the transition section, and the length is insufficient. Due to structural limitations, it cannot be used for larger tension coiling. It can only reduce the number of folds and alleviate the degree of folds, but it cannot be fundamentally solved. At the same time, the moment of inertia of the reel is large, and the cylindricity and roundness are poor, which affects the coiling quality of the strip and cannot meet the high-quality requirements. Strip curling requirements

Embodiment Construction

[0020] According to attached image 3 , 4 The present invention is further described as follows:

[0021] The hollow main shaft 12 is the main receiving body of the present invention, supporting the axial wedge 13 and the radial wedge 11 and the like. The axial wedge 13 is placed in the groove of the hollow main shaft 12, the radial wedge 11 is installed on the axial wedge 13; the multi-half sector block 8 is supported on the radial wedge 11, and is connected to the hollow main shaft through the spring body 7 12; the jaw plate 9 is installed in the radial wedge 11 through the elastic body 10; the mandrel 14 is installed in the hollow main shaft 12, one end of which is connected with the axial wedge 13 through the connecting body 17, and the other end is connected The sleeve 15 is connected with the expansion-contraction mechanism 16; the expansion-contraction mechanism 16 is installed on the hollow main shaft 12.

[0022] The expansion and contraction mechanism 16 pushes th...

Abstract

The invention belongs to the technical field of forming, and relates to a cold-rolled strip coiler reel. In the present invention, the axial oblique wedge is installed on the hollow main shaft, the radial oblique wedge is installed on the axial oblique wedge, and the two ends of the multi-half fan block are supported on the radial oblique wedge, and are connected to the hollow main shaft through a spring body; the core The shaft is installed in the hollow main shaft, one end is connected with the expansion and contraction mechanism through the connecting sleeve, and the other end is connected with the axial wedge through the connecting body. The invention is suitable for the requirements of thin strips and high-quality coiled strips, so as to adapt to different thicknesses of strips and reduce coiling rolls of strips. The reel can meet the requirements of centering movement of the edge of the coiled strip. The reel of the present invention adopts a simple and reliable connection method on the mechanism, and all its parts are easy to assemble and process, and all sides are fully processed, which not only ensures the cylindricity and uniformity of the reel, but also ensures the weight of the reel. Lightweight and strong dynamic compensation ability to meet the purpose of modern production.

Description

technical field [0001] The invention belongs to the technical field of forming, and relates to a cold-rolled strip coiler reel. Background technique [0002] In the production of strip cold rolling and cold rolling follow-up finishing line, various units need to be uncoiled and coiled, and the demand for corresponding coils is inseparable. In existing actual production, square pyramid shaft reels are often used for heavy loads with high tension, and wedge sleeve reels are often used for light loads with small tensions. However, the moment of inertia of this type of reel and the The structural defect that the bonding area cannot be completely closed makes the roundness and quality uniformity of this type of reel poor, and it is not suitable for the production line of thin strips. At the same time, the clamping of the jaws of the pyramid shaft reel cannot be driven by the expansion and contraction hydraulic pressure synchronously with the multi-half fan block, but an independ...
