Description

Technical Field

[0001] The utility model belongs to the technical field of steel plate production and processing, in particular to a water retaining device for roller steel plate production. Background Art

[0002] At present, the heat treatment production line of steel plants mainly produces normalizing plates and quenching plates, and the temperatures of the two are about 400 degrees Celsius and 80 degrees Celsius respectively. The main process of quenching plates is high-temperature austenitization in a quenching furnace, and then rapid cooling by pressurized water in a quenching machine. After quenching in the quenching machine, a large amount of water will remain on the surface of the steel plate. If it is not removed in time, the surface of the steel plate will oxidize and rust, affecting the surface quality of the steel plate and increasing the cost of rework. In order to solve this problem, the existing method is to place a wind knife device above the roller, fix the wind knife at a certain height from the roller surface, introduce compressed air, and then blow out through the gap of the wind knife to blow the water on the surface of the steel plate to the back of the steel plate to blow out the water on the upper surface of the steel plate.

[0003] Existing rollers are often open. When using an air knife device to remove water from the surface of the steel plate, water droplets are often blown back and splashed to the back of the steel plate, which can easily cause the equipment next to the roller to be corroded by water droplets and increase the maintenance cost of the equipment. Existing air knife blowing devices often need to open the air knife at a large flow rate to ensure that the water is blown dry due to the large amount of water on the surface of the steel plate, which inevitably causes excessive loss of compressed air energy. Utility Model Content

[0004] The purpose of the utility model is to provide a water retaining device for roller steel plate production to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] A water retaining device for roller steel plate production is provided, comprising a conveying roller, a water-blocking cover is provided on the conveying roller, a supporting frame is provided on one side of the water-blocking cover, the supporting frame is provided on one side of the conveying roller, a first cylinder mounting plate is provided on the supporting frame, a second cylinder mounting plate is provided on the side of the supporting frame away from the first cylinder mounting plate, a shaftless cylinder guide rod is provided between the first cylinder mounting plate and the second cylinder mounting plate, a cylinder movable block is movably connected below the shaftless cylinder guide rod, and a water retaining mechanism is fixedly connected below the cylinder movable block.

[0006] Furthermore, the water-blocking mechanism includes a first mounting plate, a second mounting plate, a guide mechanism, and a wiper. The first mounting plate is fixedly connected to the cylinder movable block, a wiper is arranged below the first mounting plate, a second mounting plate is fixedly connected to the side of the wiper away from the first mounting plate, a first guide mechanism and a second guide mechanism are respectively arranged on the first mounting plate and the second mounting plate, and the first guide mechanism and the second guide mechanism are slidably connected to the support frame.

[0009] Furthermore, a wiper plate is detachably connected between the first mounting plate and the second mounting plate.

[0010] Furthermore, a rubber layer is provided on the wiper blade.

[0011] Furthermore, a relief groove is provided on the water-proof cover.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] A water-blocking cover is installed on the quenched steel plate transported above the conveyor roller to cooperate with the conveyor roller to remove moisture from the surface of the steel plate, so that water will not leak to the equipment next to the roller;

[0014] In addition, a support frame is arranged inside the water retaining cover to drive the cylinder movable block to move through the shaftless cylinder guide rod between the first cylinder mounting plate and the second cylinder mounting plate. The production process drives the water retaining mechanism to move to just above the steel plate transported on the conveyor roller. Most of the moisture accumulated on the surface of the steel plate produced after quenching is scraped and swept, and a small part of the moisture is blown away by the subsequent wind knife device, which can effectively reduce the flow rate required for the compressed air of the wind knife and reduce the loss of compressed air energy.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 As shown, in the embodiment of the utility model, a water retaining device for roller steel plate production comprises a conveying roller 1, a water-blocking cover 2 is arranged on the conveying roller 1, a support frame 3 is arranged on one side of the water-blocking cover 2, the support frame 3 is arranged on one side of the conveying roller 1, one end of the support frame 3 extends to the inside of the water-blocking cover 2, a first cylinder mounting plate 4 is arranged on the support frame 3, a second cylinder mounting plate 5 is arranged on the side of the support frame 3 away from the first cylinder mounting plate 4, the installation position of the second cylinder mounting plate 5 is located inside the water-blocking cover 2, a shaftless cylinder guide rod 6 is arranged between the first cylinder mounting plate 4 and the second cylinder mounting plate 5, a cylinder movable block 7 is movably connected below the shaftless cylinder guide rod 6, and a water retaining mechanism 8 is fixedly connected below the cylinder movable block 7;

[0023] A water shield 2 is set on the quenched steel plate transported above the conveyor roller 1 to cooperate with the conveyor roller 1 to clear the moisture on the surface of the steel plate so that the water will not leak to the equipment next to the conveyor roller 1;

[0024] In addition, a support frame 3 is arranged inside the water shield 2, and the shaftless cylinder guide rod 6 between the first cylinder mounting plate 4 and the second cylinder mounting plate 5 drives the cylinder movable block 7 to move, and the water retaining mechanism 8 is driven to move to the top of the steel plate transported on the conveyor roller 1 during the production process, and most of the moisture accumulated on the surface of the steel plate produced after quenching is scraped and processed, while a small part of the moisture is blown away by the subsequent air knife device;

[0025] During the production of non-quenching plates, the shaftless cylinder guide rod 6 drives the cylinder movable block 7 to move again to move the entire water retaining mechanism 8 to the outside of the water-blocking cover 2, so as to prevent the high-temperature steel plates transported on the conveyor roller 1 from damaging the water retaining mechanism 8. Through the above-mentioned operation method, during the production of normalizing plates, the water retaining mechanism 8 and the water-blocking cover 2 will not affect the normal transportation of the conveyor roller 1, and during the production of quenching plates, the required flow rate of the compressed air of the air knife can be effectively reduced, thereby reducing the loss of compressed air energy.

[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the water retaining mechanism 8 includes a first mounting plate 81, a second mounting plate 82, a first guide mechanism 83, a second guide mechanism 84, and a wiper plate 85. The first mounting plate 81 is fixedly connected to the cylinder movable block 7, a wiper plate 85 is arranged below the first mounting plate 81, a second mounting plate 82 is fixedly connected to the wiper plate 85 on a side away from the first mounting plate 81, and the first mounting plate 81 and the second mounting plate 82 are respectively provided with a first guide mechanism 83 and a second guide mechanism 84 which are slidably connected to the support frame 3, and are used to For guidance, the shaftless cylinder guide rod 6 arranged between the first cylinder mounting plate 4 and the second cylinder mounting plate 5 provides support and stability, ensuring that the entire water retaining mechanism 8 will not shake or tilt during operation. A cylinder movable block 7 is slidably connected below the shaftless cylinder guide rod 6. The cylinder movable block 7 can move left and right on the support frame, driving the wiper plate 85 to move to the inside of the water-blocking cover 2 until the wiper plate 85 is located directly above the conveying steel plate on the conveyor roller 1, thereby scraping off most of the water on the upper surface of the quenched steel plate.

[0027] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the first guide mechanism 83 includes two first bearing seats 831, and the two first bearing seats 831 are symmetrically arranged on the first mounting plate 81. The first bearing seats 831 are rotatably connected to the first guide rollers 832, and the first guide rollers 832 are slidably connected to the support frame 3. When the first mounting plate 81 moves on the shaftless cylinder guide rod 6 through the cylinder movable block 7, the first guide rollers 832 move and slide along the support frame 3, which can ensure the stability of the wiper blade 85 during movement.

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the second guide mechanism 84 includes two second bearing seats 841, and the two second bearing seats 841 are symmetrically arranged on the second mounting plate 82. The second bearing seats 841 are rotatably connected to the second guide rollers 842, and the second guide rollers 842 are slidably connected to the support frame 3. Similarly, when the second mounting plate 82 moves on the shaftless cylinder guide rod 6 through the cylinder movable block 7, the second guide rollers 842 can also move and slide along the support frame 3, further ensuring the stability of the wiper blade 85 during movement.

[0029] In one embodiment, see Figure 1 and Figure 3 As shown, a wiper plate 85 is detachably connected between the first mounting plate 81 and the second mounting plate 82, so that the wiper plate 85 can be easily removed and replaced. When the wiper plate 85 needs to be cleaned or replaced, the operator can easily remove it from the connection between the first mounting plate 81 and the second mounting plate 82.

[0030] In one embodiment, see Figure 1 and Figure 3 As shown, a rubber layer 851 is provided on the wiper blade 85. The softness of the rubber material can effectively contact the surface of the steel plate and can adapt to the contour of the surface of the steel plate, thereby effectively scraping off moisture. In addition, the provision of the rubber layer 851 can also reduce the wear on the surface of the steel plate and ensure the quality and surface condition of the steel plate during the production process.

[0031] In one embodiment, see Figure 1 As shown, the water shield 2 is provided with a clearance groove 21 to make room for the entire water retaining mechanism 8 to move into the water shield 2 .

[0032] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
