Description

A high-precision cold rolling forming device for space frame structures Technical Field

[0001] This utility model relates to the field of cold rolling equipment technology, and in particular to a high-precision cold rolling forming device for space frame structures. Background Technology

[0002] Cold rolling is a processing technology that applies pressure to metal at room temperature using rolls to induce plastic deformation, thereby obtaining the desired shape and size. Compared with hot rolling, cold-rolled steel has higher dimensional accuracy, better surface quality, and higher strength. Cold rolling equipment typically consists of a roll system, drive system, control system, measurement system, lubrication system, etc.

[0003] The lubrication system plays several roles: 1. It can reduce the coefficient of friction and friction force on the contact arc surface of the deformation zone, thereby increasing the rolling speed and reducing the minimum rollable thickness; 2. It can reduce the wear of the rolls; 3. It can prevent metal from sticking (welding) to the rolls; 4. The lubricant can also act as a cooling medium and a detergent, so the lubrication system is crucial in rolling equipment.

[0004] However, the lubricants used in existing cold rolling equipment lubrication systems are usually water-oil mixtures or emulsions. Therefore, the lubricants need to be pretreated to ensure that the water and oil are fully mixed or in an emulsified state. As production time increases, the water and oil in the pretreated lubricant will gradually separate or exit the emulsified state, so it must be used within a specified time, which imposes certain limitations on production. Furthermore, since the lubricant also functions as a detergent during production, the lubrication system itself can be regarded as a cleaning system to clean the rolls. However, during production, due to liquid splashing and the lubricant's own tendency to attract dirt, dirt accumulates more easily in areas around the rolls that the lubrication system cannot directly rinse. However, due to structural limitations, the existing lubrication system cannot clean areas outside the rinsing range, resulting in a large amount of dirt around the rolls. Summary of the Invention

[0005] This invention solves the problems mentioned in the background art by having the lubricant be mixed twice in the premix box, and by having the spray head structure swing laterally back and forth while the atomizing head moves back and forth like a blooming flower during cleaning, constantly changing the position and range of the rinsing. Therefore, the atomizing head can clean the roll and all the surrounding areas of the roll without dead angles, so that the area around the roll can also be cleaned.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision steel cold rolling forming device for a space frame structure, comprising a frame, a feeding structure installed on one side of the top of the frame, a conveying structure installed on one side of the feeding structure, a cold rolling frame installed on one side of the conveying structure, a rolling mill structure installed inside the cold rolling frame, a sliding frame fixedly installed above the rolling mill structure, a supply structure slidably inserted into the sliding frame, a steering frame fixedly connected to the bottom end of the supply structure, a drive motor fixedly connected to the bottom end of the steering frame, a movable frame fixedly connected to the bottom end of the drive motor, a premixing structure fixedly connected to the bottom end of the movable frame, a spray head structure fixedly inserted into the bottom end of the premixing structure, and a recycling structure provided inside the frame.

[0007] Preferably, the supply structure includes a sliding block, the sliding block is hollow inside, a flexible connecting tube is fixedly inserted into the top of the sliding block, the top of the flexible connecting tube is fixedly inserted into the top of the cold rolling frame, and a supply body is fixedly inserted into the end of its top.

[0008] Preferably, the steering frame includes an upper rotating bar, the top end of which is fixedly connected to the bottom end of a sliding block, a lower rotating bar rotatably connected to one side of the bottom end of the upper rotating bar, a rotating handle fixedly installed on one side of the lower rotating bar, and the bottom end of the lower rotating bar fixedly connected to a drive motor.

[0009] Preferably, the movable frame includes a vertical gear rod, and a horizontal moving groove is sleeved on the outer side of the vertical gear rod through incomplete gear meshing. Two limiting rods are fixedly provided at the bottom end of the horizontal moving groove. A horizontal gear rod is connected to the bottom end of the vertical gear rod through bevel gear meshing. A vertical moving groove is sleeved at one end of the horizontal gear rod through incomplete gear meshing. One side of both the horizontal moving groove and the vertical moving groove 1004 is slidably connected to a sliding block. A lifting rod is fixedly connected to the bottom end of the vertical moving groove.

[0010] Preferably, the premixing structure includes a premixing box, with two sides of the premixing box corresponding to the positions of two limiting rods respectively. An upper hollow tube is fixedly inserted into the top of the premixing box, and an air outlet is fixedly opened on one side of the upper hollow tube. Flexible gas delivery tubes and flexible liquid delivery tubes are fixedly inserted into the two sides of the premixing box respectively. The bottom end of a sliding block is fixedly inserted into the top of each of the flexible gas delivery tubes and flexible liquid delivery tubes. Two opposing stirring wheels are installed inside the premixing box, with one side of each stirring wheel corresponding to the inlet position of the flexible gas delivery tube and the flexible liquid delivery tube respectively.

[0011] Preferably, the spray head structure includes a lower hollow tube, the top end of which is fixedly inserted into the bottom end of the premix box, and a rubber sheet is fixedly connected to the bottom end of the lower hollow tube. Multiple atomizing heads are regularly installed on the bottom end of the rubber sheet, and the top ends of the atomizing heads are all fixedly inserted into the lower hollow tube through corresponding flexible connecting tubes that pass through the top end of the rubber sheet.

[0012] Preferably, the spray head structure further includes multiple annular plates, which are arranged from top to bottom in ascending order of size. The top annular plate is fixedly connected to the lower hollow tube, while the remaining annular plates are slidably connected to the lower hollow tube. The bottommost annular plate corresponds to the position of the lifting rod. The multiple annular plates correspond to the positions of multiple atomizing heads in a regular pattern, and the bottom ends of the multiple annular plates are fixedly connected to the rubber sheet at the top of the corresponding atomizing head via connecting lines.

[0013] Preferably, both sides of the cold rolling frame are fixedly installed with a shielding curtain, the shape of which corresponds to the shape of the cold rolling frame and is made of a hydrophobic material. The bottom of the cold rolling frame is provided with a corrugated guide plate, and the valley of the corrugated guide plate is connected to the recycling structure inside the frame.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when the equipment is in use, the air and lubricant in the premix box can be fully mixed by the stirring wheel, so that the water and oil in the lubricant are fully mixed or in an emulsified state, which extends the service life of the lubricant. Even when the steel stops cold rolling and the spray head structure is closed, the air supply pipe can still supply air normally. At this time, the air reaches the premix box and is discharged from the air outlet of the upper hollow tube. During this process, the corresponding stirring wheel can still be driven to rotate, so as to stir the lubricant remaining in the premix box evenly and keep the lubricant in a fully mixed or emulsified state, thereby solving the problem of water and oil separation in the lubricant caused by the extension of production time.

[0016] 2. In this utility model, when the equipment needs cleaning, the drive motor starts and drives the vertical gear rod to rotate. This, in turn, drives the horizontal moving trough to move back and forth rhythmically via the incomplete gear on the vertical gear rod. As the horizontal moving trough moves back and forth rhythmically, the two limit rods drive the premix box to swing laterally back and forth, causing the spray head structure below to swing laterally with the premix box. Simultaneously, the bevel gear on the vertical gear rod drives the horizontal gear rod to rotate, which in turn drives the vertical moving trough to move up and down via the incomplete gear on the horizontal gear rod. As the vertical moving trough moves up and down, the lifting rod drives multiple annular plates to move sequentially from bottom to top. These annular plates then pull corresponding rubber sheets via connecting lines, causing the corresponding atomizing heads to move back and forth like blooming flowers. Because the spray head structure swings laterally with the premix box while the atomizing heads move back and forth like blooming flowers, constantly changing the position and range of the rinsing, the atomizing heads can clean the rollers and their surrounding areas without any blind spots, ensuring that the area around the rollers is also thoroughly cleaned.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Referring to Figures 1-5: A high-precision steel cold rolling forming device for a space frame structure includes a frame 1. A feeding structure 2 is installed on one side of the top of the frame 1. A conveying structure 3 is installed on one side of the feeding structure 2. A cold rolling frame 4 is installed on one side of the conveying structure 3. A roller structure 5 is installed inside the cold rolling frame 4. A sliding frame 6 is fixedly installed above the roller structure 5. A supply structure 7 is slidably inserted into the sliding frame 6. An adjusting frame 8 is fixedly connected to the bottom end of the supply structure 7. A drive motor 9 is fixedly connected to the bottom end of the adjusting frame 8. A movable frame 10 is fixedly connected to the bottom end of the drive motor 9. A premixing structure 11 is fixedly connected to the bottom end of the movable frame 10. A spray head structure 12 is fixedly inserted into the bottom end of the premixing structure 11. A recycling structure is provided inside the frame 1.

[0026] The supply structure 7 includes a sliding block 701, which is hollow inside. A flexible connecting tube 702 is fixedly inserted into the top of the sliding block 701. The top of the flexible connecting tube 702 is fixedly inserted into the top of the cold rolling frame 4, and the end of its top is fixedly inserted into the supply body 703.

[0027] The steering frame 8 includes an upper rotating bar 801, the top end of which is fixedly connected to the bottom end of a sliding block 701. A lower rotating bar 802 is rotatably connected to one side of the bottom end of the upper rotating bar 801. A handle 803 is fixedly installed on one side of the lower rotating bar 802. The bottom end of the lower rotating bar 802 is fixedly connected to a drive motor 9.

[0028] The premixing structure 11 includes a premixing box 1101. The two sides of the premixing box 1101 correspond to the positions of two limiting rods 1005 respectively. An upper hollow tube 1102 is fixedly inserted into the top of the premixing box 1101. The top of the upper hollow tube 1102 is rotatably connected to the bottom end of the vertical gear rod 1001. An air outlet is fixedly opened on the top of one side of the upper hollow tube 1102. Flexible gas delivery tubes 1103 and flexible liquid delivery tubes 1104 are fixedly inserted into the two sides of the premixing box 1101 respectively. The bottom end of the sliding block 701 is fixedly inserted into the top of both the flexible gas delivery tubes 1103 and the flexible liquid delivery tubes 1104. Two opposing stirring wheels 1105 are installed inside the premixing box 1101. One side of each stirring wheel 1105 corresponds to the inlet position of the flexible gas delivery tube 1103 and the flexible liquid delivery tube 1104 respectively.

[0029] In this embodiment, when the equipment is in use, the air and lubricant in the premix box 1101 can be fully mixed by the stirring wheel 1105, so that the water and oil in the lubricant are fully mixed or in an emulsified state, thus extending the service life of the lubricant. Even when the steel stops cold rolling and the spray head structure 12 is closed, the air supply pipe can still supply air normally. At this time, after the air reaches the premix box 1101, it is discharged from the air outlet of the upper hollow tube 1102. During this process, the corresponding stirring wheel 1105 can still be rotated to stir the lubricant remaining in the premix box 1101 evenly, keeping the lubricant in a fully mixed or emulsified state, thereby solving the problem of water and oil separation in the lubricant caused by the extension of production time.

[0030] This utility model allows the position of the spray system to be adjusted by sliding the position of the sliding block 701. By rotating the handle 803, the lower rotating bar 802 can be rotated, thereby changing the orientation of the spray head structure 12. That is, by adjusting the sliding block 701 and the handle 803, the spray head can better adapt to the rolling of steel of different sizes and shapes.

[0031] Example 2: As shown in Figures 3-5: The movable frame 10 includes a vertical gear rod 1001. A horizontal moving groove 1002 is sleeved on the outer side of the vertical gear rod 1001 via an incomplete gear engagement. Two limiting rods 1005 are fixedly provided at the bottom end of the horizontal moving groove 1002. A horizontal gear rod 1003 is connected to the bottom end of the vertical gear rod 1001 via a bevel gear engagement. A vertical moving groove 1004 is sleeved on one end of the horizontal gear rod 1003 via an incomplete gear engagement. One side of both the horizontal moving groove 1002 and the vertical moving groove 1004 is slidably connected to a sliding block 701. A lifting rod 1006 is fixedly connected to the bottom end of the vertical moving groove 1004.

[0032] The spray head structure 12 includes a lower hollow tube 1201. The top end of the lower hollow tube 1201 is fixedly inserted into the bottom end of the premix box 1101. A rubber sheet 1202 is fixedly connected to the bottom end of the lower hollow tube 1201. Multiple atomizing heads 1203 are regularly installed on the bottom end of the rubber sheet 1202. The top end of each atomizing head 1203 is fixedly inserted into the lower hollow tube 1201 through a corresponding flexible connecting tube 702.

[0033] The spray head structure 12 also includes multiple annular plates 1204, which are arranged from top to bottom in ascending order of size. The top annular plate 1204 is fixedly connected to the lower hollow tube 1201, while the other annular plates 1204 are slidably connected to the lower hollow tube 1201. The bottommost annular plate 1204 corresponds to the position of the lifting rod 1006. The multiple annular plates 1204 correspond to the positions of multiple atomizing heads 1203 in a regular pattern, and the bottom ends of the multiple annular plates 1204 are fixedly connected to the rubber sheet 1202 at the top of the corresponding atomizing head 1203 via connecting lines.

[0034] Both sides of the cold rolling frame 4 are fixedly installed with a shielding curtain 101. The shape of the shielding curtain 101 corresponds to the shape of the cold rolling frame 4, and it is made of hydrophobic material. The bottom of the cold rolling frame 4 is provided with a wave-shaped guide plate 102. The valley of the wave-shaped guide plate 102 is connected to the recycling structure inside the frame 1.

[0035] In this embodiment, when the equipment needs cleaning, the drive motor 9 starts and drives the vertical gear rod 1001 to rotate. This, in turn, drives the transverse moving trough 1002 to move back and forth rhythmically via the incomplete gear on the vertical gear rod 1001. As the transverse moving trough 1002 moves back and forth rhythmically, the two limit rods 1005 drive the premix box 1101 to swing laterally back and forth, causing the lower spray head structure 12 to follow the lateral swing of the premix box 1101. Simultaneously, the bevel gear on the vertical gear rod 1001 drives the horizontal gear rod 1003 to rotate, which in turn drives the vertical moving trough 1004 to move up and down via the incomplete gear on the horizontal gear rod 1003. When the vertical moving groove 1004 moves up and down reciprocally, the lifting rod 1006 drives multiple annular plates 1204 to move sequentially from bottom to top. This causes the multiple annular plates 1204 to pull the corresponding rubber sheets 1202 through the connecting line, causing the corresponding atomizing heads 1203 to move back and forth like blooming flowers. As the spray head structure 12 swings laterally with the premix box 1101, the atomizing heads 1203 move back and forth like blooming flowers, constantly changing the position and range of the rinsing. Therefore, during rinsing, the atomizing heads 1203 can clean the roller and all the surrounding areas of the roller without dead angles, so that the area around the roller can also be cleaned.

[0036] Working principle: When the equipment is running, the steel enters from the feeding structure 2, passes through the conveying structure 3, and arrives at the rolling structure 5 inside the cold rolling frame 4, where it is cold rolled by the rolling structure 5. During the cold rolling process, the supply structure 7 inputs air and lubricant through the supply body 703. The air and lubricant go from the supply body 703 through the flexible connecting pipe 702 to the sliding block 701, and then through the flexible air supply pipe 1103 and the flexible liquid supply pipe 1104 to the premix box 1101. Since one side of the two stirring wheels 1105 corresponds to the inlet position of the flexible air supply pipe 1103 and the flexible liquid supply pipe 1104, the air and lubricant will drive the two stirring wheels 1105 to rotate relative to each other when they enter the premix box 1101, which will fully mix the air and lubricant. Then the air and lubricant are sprayed out from the atomizing head 1203 through the lower hollow pipe 1201 to lubricate and cool the steel.

[0037] By operating according to the above description, the use of a high-precision steel cold rolling forming device for space frame structures can be completed.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
