[0006] Still include multiple cooling water pipes, multiple the cooling water pipe are respectively arranged at the top of two parallel section side guide plates and the top of two inclined section side guide plates;Every cooling water pipe bottom is fixed with multiple support rods;The cooling water pipe bottom is equipped with multiple water outlets;The cooling water pipe one end is connected with water inlet pipe.

[0007] Preferably, multiple the cooling water pipe are arranged at the top of parallel section side guide plate and the top of inclined section side guide plate close to first lining plate and second lining plate side.

[0008] Preferably, the second lining plate is connected to the inclined section side guide plate through a bolt near one end of the first lining plate; and a plurality of gaskets are sleeved on the bolt.

[0009] Compared with the prior art, the roll former front side guide plate anti-wear device has the following advantages:

[0010] (1) The cooling water is sprayed onto the parallel section side guide plate or the inclined section side guide plate through the cooling water pipes and the water outlets, and the cooling water flows on the surface of the first lining plate or the second lining plate, so that the temperature of the side guide plate and the lining plate is reduced, and the deformation and wear of the side guide plate and the lining plate are reduced.

[0011] (2) By installing a plurality of gaskets on the bolt, when the end of the second lining plate near the first lining plate protrudes, the maintenance personnel only need to reduce the number of gaskets, so that the end of the second lining plate near the first lining plate is close to the inclined section side guide plate, the maintenance is convenient, and the replacement frequency of the lining plate is reduced.

[0012] (3) The device is simple in design and easy to use. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 is a structural schematic view of the roll former front side guide plate anti-wear device;

[0014] Figure 2 is a structural schematic view of the bolt structure after the second lining plate is removed. DETAILED DESCRIPTION

[0015] The roll former front side guide plate anti-wear device will be further described below in combination with the drawings and specific embodiments.

[0016] Embodiment 1

[0017] As shown in the drawings, Figure 1 a roll former front side guide plate anti-wear device includes a plurality of cooling water pipes 3,

[0018] The side guide plate includes a parallel section side guide plate 1 and an inclined section side guide plate 2; the parallel section side guide plate 1 and the inclined section side guide plate 2 are installed with a first lining plate 11 and a second lining plate 21 on the side close to the roller; a plurality of cooling water pipes 3 are respectively arranged on the top of the two parallel section side guide plates 1 and the top of the two inclined section side guide plates 2, and a plurality of cooling water pipes 3 can be provided on the top of one parallel section side guide plate 1 or one inclined section side guide plate 2; a plurality of support rods 31 are fixed at the bottom of each cooling water pipe 3, and the support rods 31 are connected to the parallel section side guide plates 1 and the inclined section side guide plates 2. The section side guide plate 1 or the inclined section side guide plate 2 is fixed; a plurality of water outlet holes are opened at the bottom of the cooling water pipe 3, and the cooling water in the cooling water pipe 3 is sprayed onto the parallel section side guide plate 1 or the inclined section side guide plate 2 through the water outlet holes. The cooling water flows on the surface of the first lining plate 11 or the second lining plate 21, thereby reducing the temperature of the side guide plate and the lining plate, and reducing the deformation and wear of the side guide plate and the lining plate; one end of the cooling water pipe 3 is connected to a water inlet pipe 32, and the water inlet pipe 32 is connected to an external water source, and the cooling water is transported to the cooling water pipe 3 through the water inlet pipe 32.

[0019] In this embodiment, the plurality of cooling water pipes 3 are arranged on the top of the parallel section side guide plate 1 and the top of the inclined section side guide plate 2 close to the first lining plate 11 and the second lining plate 21 to facilitate the cooling water flow on the lining plate surface.

[0020] Example 2

[0021] During the production process, the parallel section side guide plate 1 and the inclined section side guide plate 2 push the strip at a high rhythm. After cooling through the cooling water pipe 3, the temperature of the side guide plate and the liner is reduced, and the deformation and wear of the side guide plate and the liner are reduced. However, the end of the second liner 21 close to the first liner 11 is the first part of the second liner 21 that contacts the strip. After a long period of heat deformation, it is unevenly worn with other parts. The end of the second liner 21 close to the first liner 11 is still deformed faster than other parts, and will protrude from the first liner 11 and bend toward the inside of the roller, damaging the strip. During maintenance, the entire liner needs to be removed and replaced, which requires a lot of maintenance work and wastes materials.

[0022] like Figure 2 As shown, the end of the second lining plate 21 close to the first lining plate 11 is connected to the inclined section side guide plate 2 by a bolt 4; a plurality of gaskets 41 are sleeved on the bolt 4, and the end of the second lining plate 21 close to the first lining plate 11 is thinner, so that the end of the second lining plate 21 close to the first lining plate 11 maintains a horizontal plane with the other end. When the end of the second lining plate 21 close to the first lining plate 11 protrudes, the maintenance personnel only need to reduce the number of gaskets 41 to make the end of the second lining plate 21 close to the first lining plate 11 close to the inclined section side guide plate 2, which is convenient for maintenance and reduces the number of lining plate replacements.
