[0030] When the coiler valve is in the raised position, it plays a downward guiding role to guide the head of the strip into the coiler; when in the lowered position, it plays a horizontal guiding role to guide the head of the strip into the next coiler.
[0031] For the tail coiler, since there is no coiler behind the tail coiler, the tail coiler valve always remains in the raised position and only plays a downward guiding role.
[0032] In the related art, the coiler valve relies on a hydraulic component. When the tail coiler valve is in the raised position, the tail coiler valve needs to maintain an appropriate clearance value with the upper pinch roll, usually the clearance value is 1 - 3 mm. In the related art, generally, the valve is limited by the stop blocks on both sides of the valve, and gaskets are added or reduced by welding or grinding on the stop blocks to adjust the clearance. The operating space for the cushion blocks is narrow and the adjustment efficiency is low.
[0033] In the related art, there is a technical problem of low adjustment efficiency in adjusting the clearance between the tail coiler valve and the upper pinch roll. The embodiment of the present application provides an adjustment mechanism applicable to the tail coiler valve, which can at least solve to a certain extent the technical problem of low adjustment efficiency in adjusting the clearance between the tail coiler valve and the upper pinch roll.
[0034] The present application will be described below with reference to the accompanying drawings and specific embodiments:
[0035] As Figure 1 shown, an adjustment mechanism 100 applicable to the tail coiler valve includes:
[0036] A frame 110;
[0037] An upper pinch roll 120 and a lower pinch roll 130, both the upper pinch roll 120 and the lower pinch roll 130 are rotatably connected to the frame 110;
[0038] A valve 140, rotatably connected to the frame 110;
[0039] A chain hoist 150, connected between the valve 140 and the frame 110, for adjusting the clearance between the valve 140 and the upper pinch roll 120.
[0040] Specifically, the hook 151 of the chain hoist 150 is connected to the frame 110, and the hook 152 of the chain hoist 150 is connected to the valve 140. Both the upper pinch roll 120 and the lower pinch roll 130 are rotatably connected to the frame 110. Under the action of the upper pinch roll 120 and the lower pinch roll 130, the strip is conveyed along the conveying direction. The specific structures of the upper pinch roll 120 and the lower pinch roll 130 are well known to those skilled in the art and will not be elaborated here.
[0041] The valve 140 is rotatably connected to the frame 110. When the valve 140 is in the raised position, it plays a downward guiding role to guide the head of the strip into the coiler; when in the lowered position, it plays a horizontal guiding role to guide the head of the strip into the next coiler.
[0042] In the related art, as Figure 2 shown, the valve 140 is usually driven by a hydraulic component 200 to make the valve 140 in the raised position or the lowered position. When the valve 140 is in the raised position, it is also necessary to precisely control the gap between the valve 140 and the upper pinch roll 120 by adding or removing shims. If the gap between the upper pinch roll 120 and the valve 140 is too large, the strip is likely to pass out from the gap, and production accidents are likely to occur. If the gap is too small, the upper pinch roll 120 will contact the coiler valve 140, resulting in wear and other situations.
[0043] The hydraulic component 200 includes a hydraulic cylinder 210 and a connecting rod 220. The hydraulic cylinder 210 is rotatably connected to the frame 110. One end of the connecting rod 220 is rotatably connected to the piston rod of the hydraulic cylinder 210, and the other end is rotatably connected to the valve 140. Controlling the action of the hydraulic cylinder 210 can control the rise or fall of the valve 140.
[0044] In the related art, the valve 140 of the tail coiler is also driven by a hydraulic cylinder. As described above, after such a design, the gap between the valve 140 and the upper pinch roll 120 still needs to be adjusted by adding or removing shims. In addition, since the valve 140 of the tail coiler is in the raised position for a long time, the hydraulic cylinder 210, the connecting rod 220, etc. of the hydraulic component 200 are kept in the same position and do not move for a long time, and the hydraulic component 200 often fails and needs to be repaired and replaced. In serious cases, the valve 140 will slip to the lowered position, causing safety accidents.
[0045] Based on long-term work experience and research, the inventor of the present application found that for the tail coiler, if a chain block 150 is used to replace the hydraulic system and connect the valve 140 and the frame 110, not only can the position of the valve 140 be more precisely controlled without adjusting the gap by adding or removing shims, but also the structure of the tail coiler can be simplified and the production cost of the enterprise can be saved. Therefore, in the present application, the chain block 150 is used to connect the valve 140 and the frame 110, and the chain block 150 is used to adjust the gap between the valve 140 and the upper pinch roll 120.
[0046] After the present application is designed in this way, the operator can adjust the position of the valve 140 by controlling the manual chain of the hoist 150 until the gap between the valve 140 and the upper pinch roller 120 meets the required range. Under the action of the hoist 150, the valve 140 can stop at any position, so there is no need to adjust the gap by adding or reducing gaskets, which simplifies the gap adjustment operation process and improves the adjustment efficiency of the valve 140.
[0047] After the present application is designed in this way, there is no need to set up a hydraulic component 200 on the tail coiler to control the position of the valve 140. Instead, the position of the valve 140 is controlled by the hoist 150. Compared with the hydraulic component 200, the structure of the hoist 150 is simple and the installation of the hoist 150 is also relatively simple. Just hang the hook 151 of the hoist 150 on the frame 110 and the lifting hook 152 on the valve 140 to achieve the function of controlling the position of the valve 140. And compared with the hydraulic component 200, the failure rate of the method of controlling the position of the valve 140 by the hoist 150 is lower.
[0048] After the present application is designed in this way, since the valve 140 of the tail coiler is not controlled by the hydraulic component 200, the installation cost and maintenance cost of the hydraulic component 200 are saved, and thus the production cost of the enterprise is saved.
[0049] In some embodiments, the adjusting mechanism 100 applicable to the valve of the tail coiler further includes a lifting lug 160. The lifting lug 160 is fixedly connected to the upper side of the valve 140. The hook 151 of the hoist 150 is hung on the frame 110, and the lifting hook 152 of the hoist 150 is hung on the lifting lug 160.
[0050] After being designed in this way, the valve 140 and the hoist 150 are connected through the lifting lug 160. The lifting lug 160 has a lifting hole, and the hook 151 of the hoist 150 extends into the lifting hole to be hung on the lifting lug 160. The way of fixedly connecting the lifting lug 160 and the valve 140 is diverse, such as threaded connection, welding, etc., which are not limited in the present application.
[0051] In some embodiments, the lifting lug 160 is arranged on one side of the valve 140 away from the valve rotating shaft 141 of the valve 140.
[0052] The valve 140 is rotatably connected to the frame 110, and the valve rotating shaft 141 is the axis of rotation of the valve 140. The lifting lug 160 is arranged on one side of the valve 140 away from the valve rotating shaft 141 so that the hoist 150 can apply a relatively small pulling force to pull the valve 140 to rotate around the valve rotating shaft 141, which facilitates the use of the adjusting mechanism 100 applicable to the valve of the tail coiler in the present application.
[0053] In some embodiments, the frame 110 includes a cross beam 111, which is located directly above the valve rotating shaft 141, and the hook 151 is hung on the cross beam 111.
[0054] The cross beam 111 is located directly above the valve rotating shaft 141, the hook 151 is hung on the cross beam 111, and the lug 160 is installed on the side of the valve 140 away from the valve rotating shaft 141. After such a design, as Figure 1 shown, the hoisting chain of the chain block 150 is in an inclined state, and obliquely pulls the valve 140. Such a design helps to keep the whole chain block 150 away from the upper pinch roll 120, and to a certain extent, avoids the chain block 150 interfering with the operation of the upper pinch roll 120.
[0055] In some embodiments, the cross section of the cross beam 111 is J-shaped, and the hook 151 is hung on the vertical wall of the cross beam 111. Specifically, as Figure 1 shown, the opening of the hook 151 faces downward, and the hook 151 is hung on the upper end of the vertical wall.
[0056] In some embodiments, the housing 153 of the chain block 150 is located on the side of the vertical wall away from the upper pinch roll 120.
[0057] Taking Figure 1 as an example, the housing 153 of the chain block 150 is located on the right side of the vertical wall. After such a design, after the chain block 150 is connected to the lug 160 and the vertical wall of the cross beam 111, the housing 153 of the chain block 150 can closely rely on the vertical wall, which helps to make the hook 151 hang on the vertical wall more firmly.
[0058] In some embodiments, the hook 151 of the chain block 150 is also fixedly connected to the vertical wall.
[0059] To ensure the reliability of the connection, the hook 151 of the chain block 150 is not only hung on the vertical wall, but also fixedly connected to the vertical wall to prevent the hook 151 from separating from the vertical wall when the coiler is running, resulting in the valve 140 slipping to the lowered position and causing a safety accident. The hook 151 of the chain block 150 can be fixedly connected to the vertical wall by welding, wire bundling and other methods.
[0060] In some embodiments, the adjusting mechanism 100 applicable to the valve of the tail coiler further includes a cooling header, which is fixed on the cross beam 111 and is used to spray coolant on the upper pinch roll 120. Specifically, a plurality of nozzles are arranged at intervals on the cooling header, and the cooling header is also communicated with a coolant storage container. The coolant is transmitted into the cooling header under the action of a pump and then sprayed out from the nozzles onto the upper pinch roll 120 to cool the upper pinch roll 120.
[0061] In some embodiments, the adjusting mechanism 100 applicable to the valve of the tail coiler includes two chain hoists 150. Along the direction of the valve rotating shaft 141 of the valve 140, the two chain hoists 150 are respectively located on both sides of the valve 140.
[0062] The two chain hoists 150 are respectively on both sides of the valve 140 to apply forces to both sides of the valve 140 simultaneously, so as to ensure that the valve 140 is uniformly stressed, so that the gaps between various parts of the valve 140 and the upper pinch roll 120 can meet the specified requirements.
[0063] The following introduces the working principle of the adjusting mechanism 100 applicable to the valve of the tail coiler in this application:
[0064] When the gap between the upper pinch roll 120 and the valve 140 needs to be adjusted, a limiting member with the same thickness as the gap value is prepared in advance (the limiting member can be a steel strip or a limiting plate with the same thickness as the gap value, etc.). For example, if the gap needs to be adjusted to 3 mm, a limiting member with a thickness of 3 mm is prepared in advance. Place the limiting member on the upper surface of the valve 140, and then lower the upper pinch roll 120 until the upper pinch roll 120 contacts the lower pinch roll 130 and generates a pressure of about 15 - 20 kN. Then the operator pulls the hand chain of the chain hoist 150 to raise the valve 140 until the valve 140 cannot be raised. At this time, the gap between the valve 140 and the upper pinch roll 120 is adjusted to 3 mm. Then raise the upper pinch roll 120 and remove the limiting member, and the adjustment is completed.
[0065] Based on the same inventive concept, the embodiment of this application also provides a strip coiling system, including the adjusting mechanism 100 applicable to the valve of the tail coiler in the above-mentioned application of this application.
[0066] Since the strip coiling system includes the adjusting mechanism 100 for the valve of the tail coiler in this application, it naturally has all the beneficial effects of the adjusting mechanism 100 for the valve of the tail coiler, which will not be elaborated here.
[0067] The strip coiling system usually includes a transmission device for transmitting the strip, and a plurality of coilers arranged in sequence for coiling the strip, etc. The structure of the strip coiling system is diverse and is not limited in this application.
