Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of drum spring seat, specifically the structure of a winding machine drum spring seat. Background Technology
[0002] A coiler is an auxiliary device in a steel rolling mill that coils hot-rolled or cold-rolled steel into a coil shape. On hot strip mills, cold strip mills, and wire rod mills, it is located after the finishing mill stand; on single-stand reversible cold strip mills, it is installed before or after the mill. In addition, it is also installed in various finishing units such as continuous pickling lines, slitting lines, annealing lines, and coating lines. The coil is an important component of the coiler, and its main parts include the main shaft, tie rod, sector plate, pyramidal sleeve, and expansion / contraction cylinder. The expansion / contraction cylinder drives the tie rod, which, through a key or spring seat, drives the pyramidal sleeve to move back and forth on the hollow shaft, thus achieving the expansion and contraction function of the coil.
[0003] The existing coiler drum spring seat structure has certain drawbacks in use. Because the upper part of the spring seat rod is designed vertically, if the spring seat rod and the jaw wedge of the pyramidal sleeve are not perpendicular during assembly, the jaw wedge can easily collide with the root of the spring seat rod when the drum shrinks during expansion and contraction. This can lead to the spring seat rod breaking, causing economic losses, reducing the effectiveness and lifespan of the coiler drum spring seat structure, and failing to meet user needs.

[0010] As a further embodiment of this utility model: the outer wall of the spring seat is provided with an annular groove, and the fixing groove is formed in the annular groove.
[0011] As a further embodiment of this utility model: the jaw wedge is provided with an assembly hole that matches the spring seat rod; the upper seat rod is disposed in the assembly hole; the connection between the upper seat rod and the lower seat rod is disposed on the outside of the assembly hole.
[0012] As a further embodiment of this utility model: the spring seat sleeve is provided with an axial through hole; the lower vertical section of the fixing groove is rectangular; the upper vertical section of the fixing groove is trapezoidal.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
