Description
Technical Field
The utility model relates to a side guide plate body device of a coiling machine, in particular to an improved side guide plate body device of the coiling machine, and belongs to the field of hot-rolled strip steel.
Background
With the rise of Compact Strip Production (CSP), Endless Strip Production (ESP) and the mature development of hot coil box technology, the development of Strip steel with a trend of hot cooling instead of cold becomes more and more obvious, and meanwhile, the difficulties in controlling the shape of the head of thin Strip steel, successfully coiling the Strip steel and the challenges in ensuring the quality of the edge of the Strip steel are brought, and FIG. 5 is a schematic structural diagram of a side guide plate in the prior art. The pattern of coiling machine front side deflector welt that uses at present is mostly the design that straight board-like adds the below and has a plurality of circular arc structures, in order to avoid causing belted steel lower surface fish tail, guarantee rollgang's normal operating because of rollgang stalling, the circular arc height must be higher than more than the rollgang 10mm, especially equipment moves behind a period, because the stifled commentaries on classics of beating after the rollgang thermal deformation or the bearing wearing and tearing, the side deflector height of taking the circular arc this moment still needs to improve. FIG. 6 is a schematic view of the structure of the strip end in the forward direction. The end part of the strip steel belongs to an upwarping structure, the side guide plates are deviated under the action of traction force and centering clamping force when the strip steel advances, the trend of pressing roller ways of the side guide plates is obvious, and each manufacturer only can adopt to cushion the side guide plates to ensure that the height between the lowest position of the arc of the lining plates 35 of the side guide plates and the roller ways reaches 30mm to avoid the condition that the roller ways block and scratch the surface of the strip steel, and the other problem is that slight gaps 36 often exist between the lining plates 35 of the side guide plates and a mother plate 34 due to the influence of processing precision when the lining plates 35 of the side guide plates are installed. However, the head of the strip steel is mostly in the shape of an arc after being sheared by the head shearing shears, and the head, particularly the edge of the strip steel, appears in a sharp and thin arc after being rolled by the finishing mill, so that strong impact force exists under the high-speed guidance of a conveying roller way, and the edge of the strip steel is very easy to insert into a gap between the side guide plate lining plate 34 and the mother plate 35 to cause steel piling. When the plate shape of the head of incoming strip steel is a plate shape with serious lateral bending or wedge shape of a sickle bay, the head of the strip steel is easy to prick into the arc of a roller way to form steel pile.
The patent with application number 200920352159.4 in the prior art applies for a guide device of a strip steel coiler, and the scheme discloses a guide device for the inlet side of a coiler in a hot-rolled strip steel production line, which comprises guide plates arranged on two sides of the guide device and guide roller assemblies arranged on two sides of the guide device, wherein the guide roller assemblies are provided with a scheme of guiding by using vertical rollers, but the scheme is that the vertical rollers are mostly arranged into special structures so as to reduce the abrasion on the surfaces of the vertical rollers. However, the strip steel is developed towards high strengthening, the pressure of the side guide plate is increased, and the guide roller device is easy to deform to form steel pile, so that the guide roller device cannot be effectively popularized.
Fig. 7 is a schematic view of a width adjustment slide assembly provided with side guide body assemblies. The roller way 33 is formed by arranging a plurality of rollers, the rollers are driven to rotate by the roller driving device on the roller way 33, width adjusting sliding devices 30 of the side guide plate body device are arranged on two sides of the roller way 33 according to the width requirement of the produced strip steel, and each width adjusting sliding device 30 comprises an adjusting bracket 31 and a sliding device driver 32 for changing the width of the adjusting bracket 30.
When silicon steel and stainless steel are rolled by conventional hot continuous rolling, the high-speed movement of strip steel and the relative movement of the lining plates of the side guide plates are combined with the strong clamping force of the side guide plates, the contact surfaces of the strip steel and the side guide plates generate a frictional heating phenomenon, powder at the edge of the strip steel which is easy to scratch is adhered to the lining plates of the side guide plates to form a slip, the influence on the edge of the strip steel is large, particularly, the edge of the strip steel is cracked and aggravated in the production of the silicon steel, the side guide plates are required to be replaced in order to avoid the scratch of the edge of the strip steel, the replacement of the side guide plates is completely impossible in production, and most manufacturers adopt water above the side guide plates to reduce the high-temperature adhesive slip generated by the relative movement of the lining plates of the side guide plates and the strip steel. However, the measure effect is not obvious, edge cracking aggravation phenomenon caused by cold exposure can occur at the edge of the strip steel, in order to change the situation, many manufacturers adopt new technologies such as ceramic type, laser melting and adhering, laser spraying and the like in two years, the using effect is not substantially changed at present, many manufacturers can only adopt a side guide plate replacing method to avoid the problem of wasting a large amount of manpower and material resources, the cost of the wear-resistant lining plate commonly used in China at present is more than 0.5 yuan/ton, some wear-resistant lining plates are as high as 1 yuan/ton, single plates are heavy, online quick replacement cannot be achieved, a large amount of spare parts are needed, and the like.
The technical improvement is carried out aiming at the defects of the prior patent 202022394395.1 in practical application, however, the defects of tooth jumping, poor linkage precision and the like exist during chain linkage, the diameter of a disc is smaller than that of a roller way, so that the contact surface of the disc and strip steel is small, the abrasion resistance is affected, the design diameter of a disc type lining plate is smaller than that of the roller way, the upwarp height of the head of the general strip steel is less than 150mm, when the head of the strip steel is in a head warping and duck head shape, the upwarp height of the head of the strip steel is the same as the height of an arc clearance on the disc lining plate, and the strip steel is easily inserted into a gap along with the rotation of the disc lining plate to stack steel.
How to overcome the disadvantages of the above patents is a problem which always puzzles the technicians in this field.
