Description

Technical Field

[0001] The utility model relates to the technical field of high-speed wire rod production, in particular to an improved device for reducing the surface indentation at the tail of hot-rolled wire rods. Background Technique

[0002] The high-speed wire rod production line is a production line specialized in producing wire rod coils. The final rolling speed can reach 110m / s. The billet with a 150*150 end face is rolled into a wire rod finished product with a specification of Φ5.5mm through rough rolling, intermediate rolling, pre-finishing rolling, rotary guide grooves and finishing mill units with alternating horizontal and vertical arrangements. After leaving the finishing mill unit and being cooled by the water tank, it is fed by the pinch roll device into the coiler, and the wire is coiled into a wire rod coil. The pinch roll device mainly consists of an inlet guide plate, an outlet guide plate and a roll ring. Its main function is to ensure that the head of the wire has enough speed to enter the coiler and reduce the excessive tail jitter, so as to complete the subsequent coiling of the wire into a wire rod coil.

[0003] After the tail of the wire rod breaks away from the finishing mill unit, the pinch roll device in front of the coiler feeds the wire rod. Since the tail of the wire rod is in a free state, the wire rod shakes violently in the guide groove, resulting in the wire rod not always being in the central rolling line position, and causing the surface indentation of the tail wire rod to exceed the tolerance when passing through the roll ring pinch.

[0004] Therefore, we propose an improved device for reducing the surface indentation at the tail of hot-rolled wire rods to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to provide an improved device for reducing the surface indentation at the tail of hot-rolled wire rods to solve the problem of surface indentation caused by excessive shaking of the tail of the wire rod in the inlet guide plate during the feeding process as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an improved device for reducing the surface indentation at the tail of hot-rolled wire rods, including a feeding structure. The feeding structure includes a feeding roll component and an adjustment component installed outside the feeding roll component. A lower stabilizing component is installed on the lower side of one end of the feeding roll component, and an upper stabilizing component is installed above the lower stabilizing component at one end of the feeding roll component;

A lubricating roller is movably installed inside the lower slotted groove, and an oil-absorbing sponge block is installed on one side of the lubricating roller inside the lower slotted groove.

[0010] Preferably, the lower stabilizing member includes lower side strips installed on the lower side of one end of the lower guide plate. There are two groups of lower side strips, and the two groups of lower side strips are installed on both sides of the square groove. A restraining roller A is movably installed between the two groups of lower side strips.

[0011] Preferably, the upper stabilizing member includes an inverted U-shaped sliding frame and a restraining roller B movably installed inside the inverted U-shaped sliding frame.

[0012] Preferably, a fixing strip is installed at one end of the upper guide plate, and the fixing strip is arranged above the square groove. Side strips are installed on both sides of the bottom end of the fixing strip, and the two fixing strips are arranged outside the square groove.

[0013] Preferably, a bolt body is threadedly connected to the middle end of the fixing strip, and the bottom end of the bolt body is movably installed at the top end of the inverted U-shaped sliding frame.

An upper guide plate 113 is provided above the lower guide plate 111, and a square groove 112 is also opened at the bottom end of the upper guide plate 113.

[0025] The adjustment member 12 includes a side empty strip 121 installed outside the lower guide plate 111. A cylinder 122 is installed inside the side empty strip 121. A top strip 124 is installed outside the upper guide plate 113. An inner sliding frame 123 is installed at the bottom end of the top strip 124. The moving end of the cylinder 122 is installed inside the inner sliding frame 123, and the inner sliding frame 123 matches the inner side of the side empty strip 121. When the cylinder 122 contracts, the upper guide plate 113 moves downward. After the square grooves 112 opened on the surfaces of the lower guide plate 111 and the upper guide plate 113 are aligned, a square with a width of 10 mm × 8 mm is formed to clamp the wire rod.

[0026] In this embodiment: The cylinder 122 contracts, and the inner sliding frame 123 moves into the side empty strip 121. When the bottom end of the top strip 124 contacts the top end of the side empty strip 121, the lower guide plate 111 contacts the upper guide plate 113. A square with a height of 10 mm × width of 8 mm is formed by the square groove 112 opened at the top end of the lower guide plate 111 and the square groove 112 opened at the bottom end of the upper guide plate 113, which restricts the wire with a Φ5.5 mm specification, effectively reducing the jitter of the wire inside it. When the wire passes through the roll ring pinch, it is at the central rolling line position, effectively avoiding the problem of excessive surface indentation at the tail of the wire and ensuring product quality and production safety.

[0027] Embodiment Two: Please refer to Figures 2-4 , on the outer surface of the lower guide plate 111 and at the bottom end of the square groove 112, a lower opening groove 114 is opened. A lubricating roller 115 is movably installed inside the lower opening groove 114. An oil-absorbing sponge block 116 is installed on one side of the lubricating roller 115 inside the lower opening groove 114. The oil-absorbing sponge block 116 lubricates the lubricating roller 115, and when the wire contacts the lubricating roller 115, it can be lubricated.

[0028] The lower stabilizing member 13 includes lower side strips 131 installed at one end of the lower guide plate 111, and there are two groups of the lower side strips 131. The two groups of the lower side strips 131 are installed on both sides of the square groove 112. A restraining roller A132 is movably installed between the two groups of the lower side strips 131, and the top end of the restraining roller A132 is flush with the bottom end of the square groove 112.

[0029] The upper stabilizing member 14 includes an inverted U-shaped sliding frame 143 and a restraining roller B144 movably installed inside the inverted U-shaped sliding frame 143, and the restraining roller B144 is above the square groove 112.

[0030] One end of the upper guide plate 113 is installed with a fixing strip 142, and the fixing strip 142 is arranged above the square groove 112. On both sides of the bottom end of the fixing strip 142, side strips 141 are installed, and the two fixing strips 142 are arranged outside the square groove 112. The inverted U-shaped sliding frame 143 is arranged between the two groups of side strips 141 to restrict the downward movement of the inverted U-shaped sliding frame 143.

[0031] The middle of the fixing strip 142 is threadedly connected with a bolt body 145, and the bottom end of the bolt body 145 is movably installed at the top end of the inverted U-shaped sliding frame 143. Rotating the bolt body 145 can control the positions of the inverted U-shaped sliding frame 143 and the restraining roller B144.

[0032] In this embodiment: Rotate the bolt body 145 to move the lower push-down U-shaped sliding frame 143 between the side strips 141, and make the restraint roller B144 approach the restraint roller A132. When pulling the wire, the restraint roller B144 and the restraint roller A132 can be used to clamp the wire in advance to restrict the wire and avoid excessive shaking of the wire. When the end of the wire passes through the lubricating roller 115, the lubricating oil on the surface of the lubricating roller 115 can be used to lubricate the end of the wire, reduce the friction between the end of the wire and the feeding roller member 11, and reduce the shaking. The rotating lubricating roller 115 contacts the oil-absorbing sponge block 116, which is convenient for the oil-absorbing sponge block 116 to lubricate the lubricating roller 115.

[0033] Working principle: The lower guide plate 111 contacts the upper guide plate 113. The square groove 112 opened at the top of the lower guide plate 111 and the square groove 112 opened at the bottom of the upper guide plate 113 form a square with a height of 10 mm and a width of 8 mm, which restricts the wire of Φ5.5 mm specification, and can effectively reduce the shaking of the wire inside it. When the wire passes through the roll ring feeding, it is in the central rolling line position, effectively avoiding the problem of excessive surface indentation at the tail of the wire, and ensuring the product quality and production safety.
