Embodiment Construction

[0016] As shown in Fig. 1, Fig. 2 and Fig. 3, the seamless expansion and contraction reel with automatic clamping function of the present invention contains a main shaft 11, and a central hole is processed in the main shaft 11, and a moving shaft 12 is arranged in the central hole, and the center There is a sliding fit between the hole and the moving shaft 12. The cross section of one section of the front end of the main shaft 11 is a square, and three faces of the section are provided with an arc plate 13, and the main shaft 11 at the rear end of the arc plate 13 is fixed with a retaining sleeve 10 for blocking the arc plate 13. Axial grooves are processed on the four corners of the front section of the main shaft 11 in the longitudinal direction, and an axial tooth plate 15 is installed in each axial groove, and the axial tooth plate 15 and the axial groove are in a sliding fit. The front end of the axial gear plate 15 protrudes outside the front end of the main shaft 11 . ...

Abstract

The present invention discloses a seamless collapsible drum with automatic clamping function. It includes a mina shaft, a moving shaft, three curved plates and a retainer cover. On four corners of front part of said main shaft are respectively set axial recessed groove and axial toothed bar. The front end of said moving shaft is fit with seaming by means of cross shifting jaw. The curved plate is connected with said main shaft by means of spring and screw. The axial toothed bar and axial recessed groove are formed into slide fit between them. The outer side of said axial toothed bar is equipped with a radial toothed bar, they are slide-meshed together. On another face of said main shaft two narrow curved plates are set, said two narrow curved plates are connected with correspondent face of said main shaft by means of spring and screw. In the main shaft plane middle of inner side of two narrow curved plates a longitudinal slideway is set, in the longitudinal slideway interior an oblique wedge is set, the external surface of said oblique wedge is equipped with a caulking strip, and between them a slide fit is formed. The front end of said oblique wedge is connected with the front end of its moving bar by means of cross shifting jaw, guide bar and spring. The application of said collapsible drum can save labour and is safe for winding strip material, and between the main shaft and axial toothed bar they can not be locked.

Description

technical field [0001] The invention relates to a rolling mill matching equipment. Specifically, it is a seamless expansion and contraction reel with automatic clamping function used to wind up the strip when rolling the strip. Background technique [0002] It is known in the plate processing industry that after the rolling of the plate is completed with a rolling mill, the coiled plate needs to be taken off from the reel. Therefore, the diameter of the reel is required to have expansion and contraction functions. At present, the expandable and shrinkable reels used in rolling mills are all traditional reels. This traditional reel contains a main shaft with an axial center hole in the main shaft. There is a moving shaft in the center hole. There is a connecting plate at the front end of the moving shaft. The diameter of the plate is larger than that of the main shaft, which is connected to the front end of the axial tooth plate by means of screws. The section of the front...
