Description

Technical Field

[0001] This utility model belongs to the technical field of color steel tile processing equipment, specifically a cold rolling forming device for color steel sheets. Background Technology

[0002] Color-coated steel sheets are steel sheets with an organic coating, widely used in industries such as construction, home appliances, and transportation. In the construction field, they are particularly commonly used for roofs, walls, and doors of industrial and commercial buildings such as steel structure factories, airports, warehouses, office buildings, prefabricated houses, and cold storage facilities. They offer numerous advantages, including light weight, high strength, and quick installation.

[0003] Color-coated steel sheets are typically formed by cold rolling. For example, Chinese utility model patent CN219881433U discloses a color-coated steel sheet forming equipment, including a color-coated steel sheet forming machine and a lifting mechanism. The lifting mechanism includes a fixed plate, a fixed rod, a sliding block, a pin, a bearing, a rotating shaft, and pin holes. A base plate is installed at the bottom of the color-coated steel sheet forming machine, and a protective baffle is fixedly connected to the upper surface of the base plate. The lifting mechanism is provided on one side surface of the protective baffle, and a cutting mechanism is provided on the upper surface of the base plate. This color-coated steel sheet forming machine, through the arrangement of the fixed plate, fixed rod, sliding block, pin, bearing, rotating shaft, and pin holes, uses a protective baffle to limit the movement of the fixed plate. During operation, the sliding block is adjusted up and down to drive the rotating shaft to slide up and down, and the pin is inserted into the pin hole to fix the sliding block and the rotating shaft, thus allowing for better adjustments based on material changes.

[0004] In existing cold-rolled corrugated steel sheet forming equipment, during the discharge process, when the corrugated steel sheet is long, the end of the sheet being conveyed outward by the cold-rolled forming equipment droops under gravity and comes into direct contact with the upper surface of the stacked corrugated steel sheets below (e.g., ...). Figure 4 As shown in a), this leads to poor material discharge from the cold rolling forming equipment for color steel sheets; in addition, since the color steel sheets have been coated before cold rolling forming, during the discharge process, the color steel sheets being discharged are in direct contact with the color steel sheets below, which can easily scratch the coating on the surface of the color steel sheets. Utility Model Content

[0005] This utility model proposes a cold rolling forming device for color steel plates, which aims to solve the problems of poor material discharge and scratches on the coating of color steel plates in existing cold rolling forming equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cold rolling forming apparatus for color steel sheets includes a cold rolling forming machine body and a guiding device. The cold rolling forming machine body includes a base, a set of pressure rollers is installed on the upper part of the base, and a cutting component is provided at the discharge end of the upper part of the base.

[0007] Preferably, the lower part of the horizontal plate is provided with a guide groove, and the upper part of the bearing plate is provided with a guide rail. The guide groove is inserted into the outer wall of the guide rail and slides in cooperation with the guide rail.

[0008] Preferably, the top of the bearing plate is provided with an arc-shaped groove that fits the gap between the roller and the bearing plate.

[0009] Preferably, the roller is provided with a groove, and the groove is coupled to the crest structure of the color steel plate.

[0010] Preferably, the clamping assembly includes an inverted guide clamp, the inner wall of the upper part of the inverted guide clamp is a sloping structure, and the inverted guide clamp is provided with an elastic clamping piece.

[0011] Preferably, the base is provided with a guide device storage compartment, and a plurality of guide devices are placed in the guide device storage compartment. The lower end of the support plate is connected to a lifting device, and the support plate moves between the bottom of the guide device storage compartment and the upper surface of the base through the lifting device. The bottom of the guide device storage bin is sloping, and a downward-extending baffle is provided on the side of the bearing plate facing the discharge direction. The bottom of the guide device storage bin is provided with a slot to accommodate the up and down movement of the baffle.

[0016] Beneficial effects: Compared with the prior art, the present invention can achieve at least the following technical effects: 1. This utility model, by setting a guiding device, connects the end of the color steel plate output from the cold rolling forming machine body with the guiding device when the cold rolling forming machine body is discharging. The rollers of the guiding device roll in contact with the upper surface of the color steel plate on the top of the color steel plate stack, avoiding direct contact between the end of the color steel plate being discharged and the upper surface of the color steel plate on the top of the color steel plate stack. The discharge process is smoother and avoids scratches on the coating of the color steel plate surface during the discharge process, thus improving processing efficiency and yield.

[0017] 2. This utility model is equipped with a guide device storage bin. Through the cooperation of the bearing plate and the lifting device, the guide devices in the guide device storage bin can be automatically transported to the discharge end on the base, which reduces the workload of manual transfer of guide devices and further improves processing efficiency.

[0023] The present invention will be further explained below with reference to specific implementation examples.

[0024] Please see Figure 1-4This utility model proposes a cold rolling forming device for color-coated steel sheets, including a cold rolling forming machine body and a guiding device. The cold rolling forming machine body is used to complete the cold rolling forming process of the color-coated steel sheets. Figure 1 As shown, the cold rolling forming machine body includes a base 1, which is welded from a steel structure. Its upper surface is machined to ensure the flatness of the mounting surface. A set of pressure rollers 2 are installed on the upper part of the base 1. The number of pressure rollers 2 is determined according to the forming requirements of the color steel sheet, typically including multiple roughing rollers and finishing rollers. Each pressure roller 2 is fixed to the base 1 via a bearing seat. The spacing of the pressure rollers 2 can be adjusted by an adjustment mechanism to accommodate color steel sheets of different thicknesses. A cutting assembly 3 is provided at the discharge end of the upper part of the base 1. The cutting assembly 3 includes a hydraulic drive system and cutting blades, used to cut the color steel sheet to a set length after forming. A guiding device is located on the upper part of the base 1 and on the side of the discharge direction of the cutting assembly 3. Figure 2 As shown, the guide device 4 includes a horizontal plate 401, which has a rectangular structure. Rollers 403 are rotatably mounted on its lower part via a wheel frame and axle connection assembly. There are two or more rollers 403, evenly distributed on the lower part of the horizontal plate 401. A clamping assembly is provided on the upper part of the horizontal plate 401 to fix the end of the color steel plate. A support plate 7 for supporting the guide device 4 is provided on the upper part of the base 1, with its upper surface flush with the upper surface of the base 1. An elastic baffle 8 is connected to the upper part of the support plate 7. The elastic baffle 8 can be made of spring steel sheet or a combination of hinge and torsion spring. Its upper end contacts the front of the horizontal plate 401. The elastic baffle 8 remains upright in its natural state, applying a certain resistance to the horizontal plate 401.

[0025] The color-coated steel sheet coil is fed from one side of the cold rolling forming machine body and undergoes a cold rolling forming process through a set of pressure rollers 2. The pressure rollers 2 use rotational pressure to form the desired corrugated structure of the color-coated steel sheet. The formed color-coated steel sheet 9 extends out from the cutting assembly 3, which can adjust the cutting interval according to production needs. After the color-coated steel sheet 9 extends, its end docks with the clamping assembly of the guide device 4. During the docking process, the end of the color-coated steel sheet 9 first contacts the clamping assembly. Due to the resistance of the elastic baffle 8, the guide device 4 remains stationary in the initial position, allowing the clamping assembly to reliably clamp the end of the color-coated steel sheet 9. After clamping, the color-coated steel sheet 9 continues to be conveyed forward, driving the guide device 4 to move together. After the color steel plate 9 is connected to the guiding device, the guiding device 4 moves forward together with the color steel plate 9. When the color steel plate 9 extends a certain length beyond the cutting component 3 (for example, more than 1m), the front end of the color steel plate 9 bends downward due to gravity. At this time, the roller 403 of the guiding device 4 contacts the upper surface of the top layer of color steel plate 9 in the stack (e.g., Figure 4(As shown in b). The roller 403 moves along with the color steel plate 9 during its discharge action by rolling, converting the sliding friction between the color steel plate 9 and the stack into rolling friction, thus reducing movement resistance. This contact method avoids the end of the color steel plate 9 directly scraping the stack surface, thereby preventing coating scratches and obstructed discharge.

[0026] In this embodiment, the lower part of the horizontal plate 401 is provided with a guide groove 404, and the upper part of the bearing plate 7 is provided with a guide rail 702. The guide groove 404 is inserted into the outer wall of the guide rail 702 and slides in cooperation with the guide rail 702.

[0027] The guide groove 404 is a rectangular groove located at the lower part of the horizontal plate 401. Its width is slightly larger than the width of the guide rail 702, forming a sliding pair. The guide rail 702 is a long strip of steel fixed to the upper part of the support plate 7, with its length direction aligned with the discharge direction. The clearance between the guide groove 404 and the guide rail 702 is controlled between 0.5 mm and 1 mm to ensure that the guide device 4 does not wobble excessively during movement. This structure allows the guide device 4 to move in a straight line when leaving the support plate 7, maintaining accurate alignment with the color steel plate 9.

[0028] In this embodiment, the top of the bearing plate 7 is provided with an arc-shaped groove 701 that fits with the roller 403 with a clearance.

[0029] The arc-shaped groove 701 is a semi-circular groove with the same radius of curvature as the roller 403. The groove depth is one-third to one-half the diameter of the roller 403. The arc-shaped groove 701 serves as a temporary positioning feature for the roller 403, preventing it from shifting when stationary. The clearance fit design allows the roller 403 to rotate freely within the groove without jamming. When the guide device 4 moves, the roller 403 can smoothly disengage from the arc-shaped groove 701 and transition onto the surface of the stacked color steel plates.

[0030] In this embodiment, the roller 403 is further configured to have a groove, which is coupled to the corrugated steel plate 9.

[0031] By setting grooves on roller 403, the guiding device moves along the crest structure of the color steel plate 9, preventing the color steel plate 9 from deviating during the discharge process. Specifically, the size of the groove is designed according to the crest shape of the color steel plate 9, forming a nested fit. This coupling allows the guiding device 4 to move along the crest structure of the color steel plate 9, preventing the color steel plate 9 from shifting laterally during the discharge process.

[0032] In this embodiment, the clamping assembly includes a chamfered guide clamp 402, the inner wall of the upper part of the chamfered guide clamp 402 is a sloping structure, and the chamfered guide clamp 402 is provided with an elastic clamping piece 405.

[0033] The bevel angle of the upper inner wall of the U-shaped guide clamp 402 is 15 to 30 degrees, facilitating the insertion of the end of the color steel plate 9. The elastic clamping piece 405 is a spring steel sheet, fixed to the inside of the guide clamp 402 by bolts, with its lower end forming a clamping opening with the inner wall of the guide clamp 402. The initial gap of the clamping opening can be adjusted by adjusting bolts to accommodate color steel plates of different thicknesses. When the end of the color steel plate 9 is inserted, the bevel guides it into the clamping opening, and the elastic clamping piece 405 deforms to provide clamping force.

[0034] When the color steel plate 9 is discharged, it first enters the C-shaped guide clamp 402. The inclined structure plays a guiding role, and then it is inserted into the gap between the lower end of the elastic clamp 405 and the C-shaped guide clamp 402 to complete the docking of the clamping component and the color steel plate 9.

[0035] In this embodiment, the base 1 is further configured to have a guide device storage compartment 5, and a plurality of guide devices 4 are placed in the guide device storage compartment 5. The lower end of the support plate 7 is connected to a lifting device 6, and the support plate 7 moves between the bottom of the guide device storage compartment 5 and the upper surface of the base 1 via the lifting device 6. The bottom of the guide device storage chamber 5 is a slope 501. A downwardly extending baffle 703 is provided on the side of the bearing plate 7 facing the discharge direction. The bottom of the guide device storage chamber 5 is provided with a slot 503 to accommodate the up and down movement of the baffle 703.

[0036] like Figure 3 a, Figure 3 As shown in Figure b, the guide device storage compartment 5 is a rectangular compartment located inside the base 1. Its capacity can be designed according to production needs, typically storing 5 to 10 guide devices 4. The bottom slope 501 of the guide device storage compartment 5 has an inclination angle of 10 to 20 degrees, allowing the guide devices 4 to slide down onto the support plate 7 under gravity. The baffle 703 is a vertical steel plate fixed to one side of the support plate 7, and its height is greater than the depth of the guide device storage compartment 5. The slot 503 is an elongated hole, allowing the baffle 703 to pass through during lifting and lowering. When the support plate 7 descends, the baffle 703 moves down accordingly, and the guide devices 4 slide into the support plate 7 from the slope 501; when the support plate 7 rises, the baffle 703 blocks other guide devices 4 on the slope 501 to prevent interference.

[0037] After the guide device 4 docks with the color steel plate 9 and moves to the designated position, the support plate 7 begins to descend under the drive of the lifting device 6. The lifting device 6 (which can be a multi-stage cylinder or electric actuator) retracts smoothly according to a preset program, driving the support plate 7 vertically into the guide device storage chamber 5 inside the base 1 until the upper surface of the support plate 7 is flush with the lower end of the bottom slope 501 of the guide device storage chamber 5. When the output length of the color steel plate 9 reaches the preset design value (such as a standard length of 6 meters or 12 meters), the hydraulic system of the cutting component 3 drives the cutting blade to quickly complete the cutting operation (the feeding is paused during the cutting process). At this time, the operator can remove the guide device 4 from the cut end of the color steel plate 9. The recovered guide device 4 is placed into the guide device storage chamber 5 through the delivery port 502 on the side wall of the base 1. Since the bottom of the guide device storage chamber 5 is an angle-optimized slope 501 (the inclination angle is usually designed to be 15°-20°), the guide device 4 automatically slides along the slope to the position of the support plate 7 under the action of gravity. During this process, the width of the storage bin 5 of the guide device and the width of the horizontal plate 401 in the guide device 4 are designed with a clearance fit (approximately 1-2 mm clearance on one side), which ensures smooth sliding of the guide device 4 and prevents it from deflecting or jamming. When the guide device 4 slides above the support plate 7, the lifting device 6 receives the positioning signal and starts the lifting procedure. The support plate 7 rises smoothly under the lifting action of the lifting device 6, and the baffle 703 set on its edge moves upward accordingly. The baffle 703 can effectively prevent the other waiting guide devices 4 on the inclined surface 501 from sliding down, ensuring that only one device is taken at a time. When the support plate 7 rises to the point where its upper surface is flush with the working plane of the base 1, the lifting device 6 stops working. At this time, the guide device 4 accurately reaches the predetermined working position, completes the pre-positioning process, and prepares for the next work cycle. The entire recycling and pre-positioning process is automated through the cooperation of mechanical structures, effectively reducing the labor intensity of operators, while ensuring the continuity and stability of the production process.

[0038] In this embodiment, the lifting device 6 is further configured to be a multi-stage cylinder or a multi-stage electric actuator.

[0039] A multi-stage cylinder or multi-stage electric actuator is installed inside the base 1, with the top of its piston rod connected to the support plate 7. The multi-stage cylinder is driven by compressed air, and its stroke can be set according to the depth of the guide device storage compartment 5; the multi-stage electric actuator is driven by a motor, providing higher stroke accuracy. The control system of the lifting device 6 is linked with the cutting assembly 3 to achieve automatic lifting.

[0040] In this embodiment, the side wall of the storage compartment of the guide device is provided with a delivery port 502, and the base 1 is provided with an opening 101 at a position corresponding to the delivery port 502.

[0041] The inlet 502 is a rectangular opening, slightly larger than the outline of the guide device 4, to facilitate the operator in placing or removing the guide device 4. The opening 101 is aligned with the inlet 502 to form a channel.

[0042] In this embodiment, the guide device 4's horizontal plate 401 is made of engineering plastic and has a hollow structure, while the roller 403 is made of polyurethane or nylon.

[0043] The guide device 4 requires strict weight control to ensure that it does not excessively pull down the color steel plate 9 during the discharge process. In this embodiment, the horizontal plate 401 of the guide device 4 is made of engineering plastic and designed as a hollow structure. The choice of engineering plastic is mainly based on its excellent comprehensive performance. This material has high mechanical strength and can withstand the traction force and a certain impact load generated when the color steel plate is discharged; at the same time, its low density and light weight, combined with the internal hollow structure design (such as using a box-shaped or honeycomb reinforcing rib structure), significantly reduce the overall weight of the guide device 4. This lightweight design ensures that during the discharge process, the guide device will not excessively pull down the color steel plate due to its own weight, or cause it to separate from the color steel plate prematurely, thereby ensuring the stability and reliability of the guiding process. In addition, engineering plastics (such as ABS, polycarbonate, etc.) also have good dimensional stability and corrosion resistance, and can adapt to the industrial production environment.

[0044] The roller 403 is made of either polyurethane or nylon. Polyurethane rollers offer excellent elasticity and wear resistance; their soft touch effectively prevents scratches on the coating of the color steel sheet while providing sufficient friction to ensure smooth rolling of the guide device. Nylon rollers are characterized by their high strength, excellent self-lubricating properties, low coefficient of friction, low running resistance, and excellent wear resistance. Both materials effectively meet the functional requirements of the rollers when rolling in contact with the stacked color steel sheet surface. The specific choice depends on a comprehensive consideration of the coating protection level, wear life, and cost budget in actual production. The precise coupling of the roller's groove structure with the crests of the color steel sheet further ensures the accuracy and stability of the guidance.

[0045] In this embodiment, the elastic baffle 8 is hinged to the bearing plate 7, and a torsion spring is provided between the bearing plate 7 and the baffle 8. When the torsion spring is in its natural state, the elastic baffle 8 is perpendicular to the top surface of the bearing plate 7.

[0046] The hinge connection point is located at the lower end of the elastic stop plate 8, and a torsion spring is sleeved on the hinge shaft to provide restoring torque. When the guide device 4 moves, the elastic stop plate 8 is pushed to rotate, and the torsion spring accumulates energy; when the guide device 4 moves away, the torsion spring returns the elastic stop plate 8 to its original position.

[0047] In summary, this utility model provides a cold rolling forming device for color steel sheets. Its main innovation lies in the integration of an automatically circulating guide device 4. At the discharge end, the guide device 4 reliably clamps the end of the formed color steel sheet 9 and moves it together. When the color steel sheet 9 extends a certain length and hangs down, the specially designed roller 403 at the bottom of the device contacts the upper surface of the stack below. The groove structure on the roller 403 couples with the crest of the color steel sheet 9, thereby achieving smooth rolling. This design not only eliminates the risk of scratches caused by hard contact but also significantly reduces discharge resistance, solving the technical problems of poor discharge of long materials and scratches on the surface coating.

[0048] Furthermore, the built-in automated supply and recycling system further enhances convenience. The coordinated operation of the guide device storage bin 5, lifting device 6, and support plate 7 enables automatic replenishment and recycling of the guide device 4. After completing one discharge task, the guide device 4 can be recycled to the guide device storage bin, and the next guide device 4 is precisely delivered to the work position via the lifting device 6, greatly reducing manual intervention and ensuring the continuity and efficiency of production. While effectively protecting the product coating and ensuring smooth discharge, it significantly improves the automation level and overall efficiency of the production line.
