AI Technical Summary
[0002]在滚切式双边剪剪切作业中,输入的板材通过磁力推床进行剪切位置的调整,由于在磁力推床在作业过程中直接和板材表面进行接触,瞬间的磁吸使磁力推床推头和板材之间产生冲击力,造程板材表面创伤;其次由于推头的长期使用表面形成粗糙纹理、毛刺高点或表面吸附的铁屑杂物都会在工作过程中造成板材表面的划伤或压痕;再次由于板材在调整过程中,磁力推床与钢板重心偏离,调整过程中板材与磁力推床推头之间会产生相对位移,也会造成钢板表面划伤
[0009]The beneficial effects of this utility model are: it can reduce the impact force and relative displacement between the pusher and the plate, avoid damage or scratches to the plate surface, and improve the quality of steel plate production.

Abstract
Description
Technical Field
[0001] This utility model relates to a magnetic pusher for improving the surface quality of steel plates, belonging to the technical field of double-sided shearing equipment in steel rolling finishing lines of the metallurgical industry. Background Technology
[0002] In double-sided shearing operations using a rolling cutter, the input sheet metal is positioned using a magnetic pusher. Because the magnetic pusher directly contacts the sheet metal surface during operation, the instantaneous magnetic attraction creates an impact force between the pusher head and the sheet metal, causing surface damage. Secondly, the long-term use of the pusher head can lead to rough textures, burrs, or adsorbed iron filings, all of which can scratch or indent the sheet metal surface during operation. Thirdly, during adjustment, the magnetic pusher and the sheet metal's center of gravity may shift, causing relative displacement between them, which can also result in surface scratches. To reduce surface quality issues caused by these problems during production and improve product quality, it is necessary to design a protective measure to enhance the surface quality of the sheet metal products. Utility Model Content
[0003] The purpose of this invention is to provide a magnetic pusher that improves the surface quality of steel plates, reducing the impact force and relative displacement between the pusher and the plate, avoiding damage or scratches to the plate surface, and solving the problems existing in the background art.
[0004] The technical solution of this utility model is: A magnetic pusher for improving the surface quality of steel plates includes an electromagnet, a magnetic pusher tray, a magnetic pusher tray buffer layer, fixing bolts, and stop washers. The magnetic pusher tray is welded to the electromagnet, and the magnetic pusher tray buffer layer is laid flat on the magnetic pusher tray. The magnetic pusher tray buffer layer and the magnetic pusher tray are fixedly connected together in the circumferential direction by multiple fixing bolts and stop washers.
[0005] The magnetic push head tray has bolt holes in the circumferential direction that cooperate with the fixing bolts. The center of the magnetic push head tray is aligned with the center of the electromagnet and welded together.
[0006] The outer diameter of the magnetic pusher tray is φ650mm, the working surface diameter is φ480mm, the working surface thickness is 25mm, and the outer diameter thickness is 10mm.
[0007] The magnetic pusher tray buffer layer is made by cutting and manufacturing the conveyor belt, and its size matches the size of the magnetic pusher tray.
[0008] The stop washer is a combination of a flat washer and a spring washer.
[0009] The beneficial effects of this utility model are: it can reduce the impact force and relative displacement between the pusher and the plate, avoid damage or scratches to the plate surface, and improve the quality of steel plate production. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and examples.
[0012] See attached document Figure 1-5 A magnetic pusher for improving the surface quality of steel plates includes an electromagnet 1, a magnetic pusher tray 2, a magnetic pusher tray buffer layer 3, fixing bolts 4, and stop washers 5. The magnetic pusher tray 2 is welded to the electromagnet 1. The magnetic pusher tray buffer layer 3 is laid flat on the magnetic pusher tray 2. The magnetic pusher tray buffer layer 3 and the magnetic pusher tray 2 are fixedly connected together in the circumferential direction by multiple fixing bolts 4 and stop washers 5.
[0013] In this embodiment, refer to the appendix Figure 1-5 The magnetic pusher includes an electromagnet 1, a magnetic pusher head tray 2, a magnetic pusher head tray buffer layer 3, fixing bolts 4, and a stop washer 5, wherein: Electromagnet 1 is a standard component purchased from outside.
[0014] The magnetic pusher tray 2 is a machined part with an outer diameter of φ650mm and a thickness of 10mm. The working surface is φ480mm and has a thickness of 10mm. There are 16 φ13mm fixing bolt holes evenly distributed on the φ620mm circumference. It is fixed by welding after being aligned with the center of the electromagnet 1.
[0015] The magnetic pusher tray buffer layer 3 is made from an EP300 1200*5 (6+3) conveyor belt.
[0016] The fixing bolt 4 is an 8.8 grade M12*40mm standard countersunk screw, and there are a total of 16 bolts in a single magnetic pusher.
[0017] The locking shim 5 uses a combination of a national standard M12 flat shim and a spring washer.
[0018] According to the appendix Figure 2 , 3 and attached Figure 4 , 5 Molds were made separately for the magnetic pusher tray 2 and the magnetic pusher tray buffer layer 3, using the attached... Figure 4 , 5 Cut out a sufficient number of magnetic push head tray buffer layers 3 from the medium mold.
[0019] After aligning the centers of the magnetic pusher tray 2 and the electromagnet 1, weld them together and fix them in place. Lay the cut magnetic pusher tray buffer layer 3 flat on the magnetic pusher tray 2, align the bolt holes, and install the fixing bolts 4 and the locking washer 5. The buffer layer 3 can be replaced periodically according to its wear level during use. In the non-working state of the pusher head, the height difference between the working surface of the pusher head and the working horizontal plane of the conveyor rollers is 70mm.
