Description

Technical Field

[0001] This utility model relates to the field of steel bar production lines, specifically a guide clamp fixing and cooling device. Background Technology

[0002] Rolling guides are key auxiliary devices installed before and after the rolls of a rolling mill. Their main function is to precisely guide the workpiece (such as billet or bar) into the roll pass and stably exit the roll after rolling. They also prevent the workpiece from deviating, twisting, or being scratched during the rolling process, ensuring that the workpiece passes through each rolling pass smoothly according to the preset shape and size, and ultimately guaranteeing product accuracy and the safety and continuity of the rolling process.

[0003] In steel rolling technology, guides are installed in the housing of fixed guide plates at the inlet and outlet of the rolling mill. When cooling the upper and lower pressure rolls used for rolling bars, external water pipes are required to cool the roll grooves. These external water pipes need to be independently fixed, and are prone to displacement due to vibration or guide adjustments, causing the cooling water spray position to deviate and fail to accurately cover the heated areas of the roll grooves. Uneven cooling can lead to excessively high local temperatures in the roll grooves, accelerating roll surface wear or deformation, and consequently causing quality problems such as dimensional deviations in the steel bars and surface scratches. Utility Model Content

[0004] The purpose of this invention is to provide a guide clamp fixing and cooling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a guide clamp fixing and cooling device is provided, comprising a fixed box body, an opening inside the fixed box body, and a sliding guide inside the opening. A fixing plate is fixed to the top of the fixed box body, and an upper water pipe connector is inserted through the fixing plate. A dovetail plate is provided at the bottom of the fixed box body, and a lower water pipe connector is inserted through the dovetail plate. The end of the lower water pipe connector corresponds to the lower roller, and the end of the upper water pipe connector corresponds to the upper roller.

[0006] Furthermore, two sets of fixing bolts are screwed onto the side wall of the fixed box, and the ends of the fixing bolts abut against the sliding guide. The sliding guide is limited and fixed inside the fixed box by the two sets of fixing bolts.

[0007] Furthermore, the fixing plate is provided with three sets of water inlet pipe joints, and the water inlet pipe joints are in the shape of an "L". The drain pipe joints are provided with two sets, and the tail ends of the two sets of drain pipe joints are distributed in a "V" shape.

[0008] Furthermore, the sliding guide is slidably installed on the inner surface of the receiving port via a sliding groove; the bottom sides of the dovetail plate are provided with limiting seats, and the dovetail plate is installed on the base; the base is provided with two sets of limiting tracks, and the base surface is provided with waist holes on both sides.

[0009] Furthermore, the size of the limiting track is adapted to that of the limiting seat, and the limiting seat is inserted into the inside of the limiting track.

[0010] Furthermore, the limiting seat has two sets of screw holes, and the screw holes are screwed with hexagonal socket bolts.

[0011] Furthermore, the limiting seat is fixed inside the limiting track by two sets of internal hexagon bolts, and the ends of the internal hexagon bolts pass through the threaded slots and abut against the limiting track.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution uses three jets of cooling water sprayed from three sets of upper water pipe joints, which are then sprayed into the pressure grooves on the upper roll for water cooling. Simultaneously, a dovetail plate at the bottom of the fixed housing has two sets of lower water pipe joints, from which two jets of cooling water are sprayed into the pressure grooves on the lower roll for water cooling. The lower and upper water pipe joints are integrated into the fixed housing, allowing the cooling water to be concentrated and sprayed onto the rolls, achieving uniform cooling and preventing uneven cooling. No additional support structures are needed, simplifying the equipment layout and avoiding cluttered piping. 2. This solution uses waist holes on both sides of the base surface to facilitate fine-tuning of the lateral installation position of the fixed box according to actual rolling requirements, thereby improving equipment adaptability. The limit seat is fixed by two sets of internal hexagonal bolts passing through the screw slot holes and contacting the limit track, thereby realizing the longitudinal position adjustment of the fixed box and reducing the difficulty of position adjustment and maintenance.

[0013] 3. The dovetail plate, slide, and fixing bolts in this design allow the guides and cooling water to be accurately adjusted to align with the roll grooves when rolling steel of different specifications. Attached Figure Description

Detailed Implementation

[0016] Please see Figure 1-5 This utility model provides a guide clamp fixing and cooling device, including a fixed box body 1, an opening 10 inside the fixed box body 1, and a sliding guide 14 inside the opening 10. A fixing plate 11 is fixed on the top of the fixed box body 1, and a water inlet pipe connector 111 is inserted through the fixing plate 11. A dovetail plate 12 is provided at the bottom of the fixed box body 1, and a water outlet pipe connector 121 is inserted through the dovetail plate 12. The end of the water outlet pipe connector 121 corresponds to the lower roller 3, and the end of the water outlet pipe connector 111 corresponds to the upper roller 2, for cooling the roller groove.

[0017] Working principle: During use, the sliding guide 14 is installed inside the fixed housing 1 and fixed with two sets of fixing bolts 13. At this time, the blank inserted inside the sliding guide 14 enters between the upper roller 2 and the lower roller 3, and the upper roller 2 and the lower roller 3 press the metal blank. During the pressing process of the upper roller 2 and the lower roller 3, the fixed plate 11 located at the top of the fixed housing 1 is equipped with three sets of water inlet pipe joints 111, and three streams of cooling water flow from the three sets of water inlet pipe joints 111. The water is sprayed out and sprayed into the pressure groove on the upper roll 2 for water cooling. At the same time, the dovetail plate 12 at the bottom of the fixed box 1 is equipped with two sets of water pipe joints 121. Two streams of cooling water are sprayed out from the two sets of water pipe joints 121 and sprayed into the pressure groove on the lower roll 3 for water cooling. The water pipe joints 121 and the upper water pipe joints 111 are integrated and installed on the fixed box 1, so that the cooling water can be concentrated and sprayed onto the roll, so as to achieve uniform cooling of the roll and avoid uneven cooling of the roll.

[0018] In a preferred embodiment, the sliding guide 14 is slidably installed on the inner surface of the receiving port 10 through a sliding groove. Two sets of fixing bolts 13 are screwed onto the side wall of the fixed box 1, and the ends of the fixing bolts 13 abut against the sliding guide 14. The sliding guide 14 is limited and fixed inside the fixed box 1 by the two sets of fixing bolts 13.

[0019] The fixed plate 11 is provided with three sets of water inlet pipe joints 111, and the water inlet pipe joints 111 are in the shape of "L". The drain pipe joints 121 are provided with two sets, and the tail ends of the two sets of drain pipe joints 121 are distributed in the shape of "V".

[0020] like Figure 1-4As shown: the lower water pipe connector 121 and the upper water pipe connector 111 are integrated and installed on the fixed box 1, which can keep the cooling water spray position fixed relative to the upper roll 2 and the lower roll 3, and will not shift due to rolling vibration or adjustment of the sliding guide 14. The cooling water can be sprayed into the pressure groove of the upper roll 2 and the lower roll 3 to ensure uniform cooling, reduce wear or deformation of the roll groove caused by local overheating, and thus ensure the dimensional accuracy and surface quality of the rolled blank. At the same time, there is no need to design additional support or other fixed structures, which simplifies the equipment layout and avoids messy pipelines. When disassembling and assembling the sliding guide 14 or changing rolls through the fixing bolts 13, there is no need to disconnect the water pipes, shortening the downtime.

[0021] As a preferred embodiment, the dovetail plate 12 is provided with limiting seats 1211 on both sides of its bottom, and the dovetail plate 12 is installed on the base 122; the base 122 is provided with two sets of limiting tracks 123, and waist holes are provided on both sides of its surface.

[0022] The size of the limiting track 123 is adapted to that of the limiting seat 1211, and the limiting seat 1211 is inserted into the inside of the limiting track 123.

[0023] The limiting seat 1211 has two sets of screw holes 125, and the screw holes 125 are screwed with hexagonal socket bolts 124.

[0024] The limiting seat 1211 is fixed inside the limiting rail 123 by two sets of internal hex bolts 124, and the ends of the internal hex bolts 124 pass through the screw slots 125 and abut against the limiting rail 123.

[0025] like Figure 2-5 As shown: The limiting seats 1211 on both sides of the bottom of the dovetail plate 12 are size-matched and plugged into the limiting rails 123 on the base 122, which can quickly position the installation direction of the dovetail plate 12 on the base 122 to avoid deviation during installation. At the same time, the limiting rails 123 can form a lateral constraint on the limiting seats 1211 to prevent the dovetail plate 12 from lateral displacement due to vibration during the rolling process, and ensure the stability of the fixed box 1 and the internal sliding guide 14.

[0026] The waist holes on both sides of the base 122 facilitate fine-tuning of the lateral installation position of the fixed box 1 according to actual rolling requirements, improving equipment adaptability. The limiting seat 1211 is fixed to the limiting track 123 by two sets of internal hexagon bolts 124 passing through the bolt slot holes 125. This not only ensures a stable connection between the limiting seat 1211 and the limiting track 123 through bolt tightening force, but also allows for easy disassembly of the internal hexagon bolts 124 when adjustment is needed, without the need to completely disassemble the base 122 or dovetail plate 12. This enables longitudinal position adjustment of the fixed box 1, reducing the difficulty of position adjustment and maintenance. At the same time, the concealed tightening method of the internal hexagon bolts 124 can reduce the corrosion of the bolts by iron oxide scale and oil in the rolling environment, extending their service life and further ensuring the long-term stability of the connection between the dovetail plate 12 and the base 122. This indirectly ensures the accuracy of the cooling of the lower roll 3 groove by the water pipe joint 121.
