AI Technical Summary
In slitting machines, strip steel tends to sag during the cutting process, leading to dimensional deviations, especially when cutting strip steel with a thickness of 0.3mm or less.
Design a strip steel support device for longitudinal shearing disc shear, comprising a support plate and a felt. The support plate is fixed on the cutter shaft seat by a hanging beam, and the felt is in contact with the strip steel. The number and width of the support plates are determined according to the width and thickness of the strip steel, and are used to prevent the strip steel from sagging.
This effectively prevents the strip from sagging in the middle, improves cutting accuracy, and enhances product quality.

Abstract
Description
Technical Field
[0001] This utility model relates to a longitudinal shearing disc shear strip steel support device, belonging to the technical field of mechanical tools in the metallurgical industry. Background Technology
[0002] In slitting mills, disc shears can perform continuous longitudinal shearing of narrow and wide strip steel. They serve both as the longitudinal shearing source for cold-rolled strip steel and as a key piece of equipment in cold-rolled strip steel slitting and rewinding production lines. A disc shear includes a drive-side cutter shaft seat, an operating-side cutter shaft seat, upper and lower cutter shafts mounted between the drive-side and operating-side cutter shaft seats, and evenly distributed spacers on the upper and lower cutter shafts. During strip steel operation, there is a gap between the strip steel and the spacers on the lower cutter shaft. Especially when cutting strip steel with a thickness of 0.3mm or less, the strip steel's transverse stiffness is weak, and the middle of the strip steel is prone to sagging, causing dimensional deviations in the strip steel cut. Utility Model Content
[0003] The purpose of this invention is to provide a strip steel support device for longitudinal shearing discs, which can prevent the strip steel from sagging in the middle during cutting, thus avoiding dimensional deviations and solving the problems existing in the background art.
[0004] The technical solution of this utility model is:
[0005] A strip steel support device for a slitting disc shear includes an upper cutter shaft, a lower cutter shaft, spacers, a drive-side cutter shaft seat, and an operating-side cutter shaft seat. The upper and lower cutter shafts are rotatably connected at both ends to the drive-side and operating-side cutter shaft seats, respectively. Several spacers are provided on both the upper and lower cutter shafts. The device also includes felt, a support plate, and a hanging beam. Both ends of the hanging beam are fixed to the drive-side and operating-side cutter shaft seats, respectively. One side of the support plate is mounted on the hanging beam, and the other side overlaps the spacers on the lower cutter shaft. Felt that mates with the strip steel is provided on the support plate.
[0006] The pallet consists of multiple rectangular plates, each with a felt piece that matches the strip steel.
[0007] The width and number of the pallets are determined based on the width and thickness of the strip steel.
[0008] The support plate is installed on the hanging beam via a base plate and connecting bolts.
[0009] The support plate is located on the hanging beam, and the bottom plate is located below the hanging beam. The support plate and the bottom plate are connected together by connecting bolts.
[0010] The beneficial effects of this utility model are: when cutting strip steel, especially when cutting strip steel with a thickness of 0.3mm or less, it can prevent the strip steel from sagging in the middle, causing deviation in the cutting dimensions of the strip steel, and improving product quality.

[0015] The present invention will be further described below with reference to the accompanying drawings and examples.
[0016] See attached document Figure 1-3 A strip steel support device for a longitudinal slitting disc shear includes an upper cutter shaft 1, a lower cutter shaft 2, spacers 7, a transmission-side cutter shaft seat 8, and an operating-side cutter shaft seat 9. The upper cutter shaft 1 and the lower cutter shaft 2 are rotatably connected at both ends to the transmission-side cutter shaft seat 8 and the operating-side cutter shaft seat 9, respectively. Several spacers 7 are provided on both the upper cutter shaft 1 and the lower cutter shaft 2. The device also includes a felt 4, a support plate 5, and a hanging beam 10. The two ends of the hanging beam 10 are fixed to the transmission-side cutter shaft seat 8 and the operating-side cutter shaft seat 9, respectively. One side of the support plate 5 is installed on the hanging beam 10, and the other side of the support plate 5 overlaps the spacers 7 of the lower cutter shaft 2. The support plate 5 is provided with a felt 4 that cooperates with the strip steel.
[0017] In this embodiment, refer to the appendix Figure 1-3 The strip steel support device includes an upper cutter shaft 1, a lower cutter shaft 2, a strip steel 3, a felt 4, a support plate 5, a lock nut 6, a spacer 7, a transmission side cutter shaft seat 8, an operating side cutter shaft seat 9, a hanging beam 10, a base plate 11, and connecting bolts 12, wherein:
[0018] The pallet 5 is made of phenolic resin with fabric, which has low frictional resistance and low heat generation. There are multiple pallets 5, the number of which can be determined according to the width and thickness of the strip. They are distributed in the middle of the lower cutter shaft 2 to support the strip and prevent it from sagging laterally. Each rectangular plate is covered with felt 4 to support the strip and prevent it from being scratched.
[0019] The two ends of the hanging beam 10 are fixed on the transmission side cutter shaft seat 8 and the operation side cutter shaft seat 9, respectively.
