Abstract
Description
Technical Field
[0001] The utility model relates to an installation structure for a reel sector plate slider of an unwinding machine, belonging to the technical field of cold rolling unwinding and unwinding machine equipment in the metallurgical industry. Background Art
[0002] The uncoiler is a commonly used uncoiler for cold rolling, skin-passing and other units. Its reel spindle adopts a tetrahedral pyramid structure with high rigidity and high bearing capacity. Its reel is composed of four fan-shaped plates, and the radial expansion and contraction of the reel is achieved through the T-type key plate installed on the spindle. Each fan-shaped plate is installed with a radial guide slider at one end close to the reduction box. When the reel expands or contracts, the four fan-shaped plates drive the four sliders to slide on the inner end surface of the hollow shaft flange. When the unit is in high-speed production, the reel is affected by the strip steel plate type, the strip roll ellipse, etc., and the radial runout is large. Under the reciprocating action of the alternating load, the fan-shaped plate slider exerts a large overturning moment on the hollow shaft flange. The traditional structure of the hollow shaft flange window is rectangular, and cracks are easily generated at the root and expand circumferentially, which eventually leads to the flange breaking. Utility Model Content
[0003] The purpose of the utility model is to provide a mounting structure for a fan-shaped plate slider of a uncoiler drum, which can reduce the force of the fan-shaped plate slider on the hollow shaft flange when the uncoiler drum expands or contracts, avoid cracks in the hollow shaft flange, increase the service life of the hollow shaft, and solve the problems existing in the background technology.
[0004] The technical solution of the utility model is:
[0005] A uncoiler drum sector plate slider installation structure includes a sector plate, fixing bolts, a connecting plate, connecting bolts, a slider, a hollow shaft and a hollow shaft flange. The connecting plate is fixed to the end face of the sector plate close to one end of the uncoiler drum reducer by fixing bolts. The slider is connected to the connecting plate by connecting bolts. The hollow shaft flange is circular. The hollow shaft flange and the hollow shaft form an integrated structure. The hollow shaft flange is located between the connecting plate and the slider.
[0006] The sliding block is a T-shaped structure matched with the hollow shaft flange.
[0007] The end surface of the sector plate close to one end of the uncoiler drum reducer is provided with a groove matched with the connecting plate.
[0008] The connecting plate is provided with a fixing bolt hole and a connecting bolt hole which match with the fixing bolt and the connecting bolt.
[0009] The fixing bolt hole is a stepped hole matched with the fixing bolt.
[0010] The utility model has the beneficial effects of reducing the force of the fan-shaped plate slider on the hollow shaft flange when the uncoiler reel expands and contracts, avoiding cracks in the hollow shaft flange and increasing the service life of the hollow shaft.

[0022] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0023] See attached Figure 1-10 A uncoiler drum sector plate slider installation structure includes a sector plate 1, a fixing bolt 2, a connecting plate 3, a connecting bolt 4, a slider 5, a hollow shaft 6 and a hollow shaft flange 7. The connecting plate 3 is fixed to the end face of the sector plate 1 close to one end of the uncoiler drum reducer by the fixing bolt 2. The slider 5 is connected to the connecting plate 3 by the connecting bolt 4. The hollow shaft flange 7 is circular. The hollow shaft flange 7 and the hollow shaft 6 are an integrated structure. The hollow shaft flange 7 is located between the connecting plate 3 and the slider 5.
[0024] In this embodiment, refer to the attached Figure 1 , 2 The main shaft 8 of the uncoiler adopts a quadrangular pyramid structure with high rigidity and high bearing capacity. The uncoiler drum is composed of four sector plates 1. Each sector plate 1 is equipped with a radial guide slider 5 at one end close to the reduction box, and a groove 11 is opened on the end surface of the sector plate 1 close to the reducer end of the uncoiler drum. Figure 8 shown.
[0025] See attached Figure 3 The connecting plate 3 is a rectangular plate, and four fixing bolt holes 9 and four connecting bolt holes 10 are opened on the connecting plate 3, wherein the four fixing bolt holes 9 are stepped holes. The connecting plate 3 is fixed in the groove 11 on the end face of the sector plate 1 by four fixing bolts, so that the nut end of the fixing bolt 2 is flush with the end face of the connecting plate 3.
[0026] See attached Fig. 9 , 10 , the hollow shaft flange 7 and the hollow shaft 6 are an integrated structure, and the hollow shaft flange 7 is circular.
[0027] See attached Figure 3 , 4 5. According to the hollow shaft flange 7, the slider 5 is designed into a T shape. When installed, the slider 5 is connected to the connecting plate 3 through four bolts 4, wherein the attached Figure 3 In the figure, C is the sliding surface between the T-shaped slider and the hollow shaft flange 7 of the circular structure.
[0028] When the uncoiler drum expands or contracts, the arc surface of the T-shaped slider and the circular hollow shaft flange 7 forms a sliding surface C. The T-shaped slider 5 can reduce the force on the circular hollow shaft flange 7, avoid cracks in the hollow shaft flange 7, and increase the service life of the hollow shaft.
