Problems solved by technology
However, the diameter increasing plate has two obvious disadvantages: 1. The increase of the outer diameter is limited, generally only 10-30mm; 2. The installation and disassembly are very complicated and take a long time
In actual application, it is found that the spring device of the internal power device of the elastic sleeve device cannot effectively expand and contract with the reel of the coiler every time, because the strip steel entering the jaw produces resistance

Embodiment Construction
[0023] In order to have a clearer understanding of the technical features, objectives and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0024] Such as Figure 1 to Figure 8 The embodiment of the present invention provides an elastic sleeve device for increasing the inner diameter of the reel with a jaw, which is used on the coil with a jaw, and includes three sector plates 1 with identical structures and a sector with jaws. Plate 2, the four fan-shaped plates are connected in a ring shape in turn, and become figure 1 As shown, the shape is similar to a reel. The internal ribs of the fan-shaped plate 1 and the fan-shaped plate 2 are grid-like structures, which can effectively ensure the structural strength of the device.
[0025] Such as Figure 1 to Figure 8 , A plurality of spring devices 4 are arranged between the two connected sector plates, and the spring devic...

The invention relates to an elastic sleeve device for increasing the inner diameter of a winding drum of a coiler with a jaw. The elastic sleeve device comprises four fan-shaped plates, wherein the four fan-shaped plates are connected in sequence to form a steel elastic sleeve; the jaw is formed in one of the fan-shaped plates; multiple spring devices are arranged between each two adjacent fan-shaped plates; each spring device comprises a guide rod, two compressing springs and two hexagon slotted nuts; the two hexagon slotted nuts are separately fixed at two ends of the guide rod; the two springs are arranged on the guide rod in a sleeving manner and are arranged at the insides of two connected fan-shaped plates respectively; an inner arc-shaped plate is arranged at the inner side of each fan-shaped plate; an outer arc-shaped plate is arranged at the outer side of each fan-shaped plate; each fan-shaped plate is provided with a synchronous expansion and contraction mechanism which comprises a tapping steel plate, a cylinder and screws. The elastic sleeve device is simple and reliable in structure, strong in practicality and simple to mount; meanwhile, the outer diameter specification of the sleeve of the coiler with the jaw can be effectively added.
Description
Technical field [0001] The invention relates to the field of cold rolling processing, and relates to an elastic sleeve device for increasing the inner diameter of a reel with a jaw coiler. Background technique [0002] At present, the general specifications of the drum diameter of the domestic cold-rolling processing line with jaw coiler are φ510 and φ610. The outer diameter of the drum for each particular coiler with jaws is fixed, and it can only be applied to steel coils with one inner diameter. [0003] Steel coils with large inner diameters are more suitable for the production of thick, hard, and heavy steel coils to reduce the deformation of the strip, protect the internal performance of the strip, and can effectively increase the yield of the strip and increase the production capacity of the unit; at the same time, it can be expanded. Raw material specifications, designing a reel diameter increasing device is of great application value. In view of this actual situation, th...
