Description

Technical Field

[0001] This utility model relates to the field of strip steel cutting technology, specifically a strip steel cutting guide device. Background Technology

[0002] Strip steel is an indispensable key material in modern industry. It is a flat steel material with a certain width and a long length. In many stages of production, processing and application, strip steel often needs to be cut due to size adaptation, process requirements or scenario limitations. In order to solve the problems of deviation and skew that may occur in high-speed and continuous movement of strip steel, strip steel cutting guide devices are needed.

[0003] Current strip cutting guide devices generate sliding friction between the guide structure and the passing strip products, resulting in high frictional resistance and wear. Furthermore, the guide structure often requires manual application of lubricating oil by the user to achieve lubrication, making it difficult to maintain continuous lubrication between the guide structure and the strip products. Consequently, the products suffer significant losses and are prone to thermal deformation when passing through the guide structure. Based on these issues, we propose a novel strip cutting guide device. Utility Model Content

[0004] The purpose of this invention is to provide a strip cutting guide device to solve the problems of high friction loss and difficulty in continuous lubrication protection mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a strip steel cutting guide device, including a chassis, with bases slidably connected to both sides of the top of the chassis, a drive housing fixed to the bottom of the base, a motor installed at the bottom of the drive housing, a drive gear connected to the output end of the motor, driven gears evenly and movably connected inside the drive housings at both ends of the drive gear, a transmission belt wound between the driven gear and the drive gear, guide roller shafts connected to the driven gear and the drive gear sequentially installed inside the base, an oil storage box fixed on the chassis above the guide roller shaft, oil guide cylinders evenly arranged at the bottom of the oil storage box, oil distribution holes provided at the bottom of the oil guide cylinders, and oil distribution balls movably connected inside the oil distribution holes and in contact with the guide roller shaft.

[0006] As a further technical solution of this utility model, both ends of the chassis are provided with adjustment grooves, and the bottom of the base is fixed with an adjustment slider that is slidably connected to the adjustment grooves.

[0007] As a further technical solution of this utility model, the outer side wall of the adjusting slider and the inner side wall of the adjusting groove are both uniformly provided with anti-slip limiting teeth.

[0008] As a further technical solution of this utility model, telescopic cylinders are installed at the middle positions on both sides of the chassis, and the output end of the telescopic cylinder and the outer wall of the base are connected by screws to form a disassembly and installation structure.

[0009] As a further technical solution of this utility model, the top of the oil storage box is provided with a reserved oil filling port, and a sealing plug is threaded onto the reserved oil filling port.

[0010] As a further technical solution of this utility model, the outer wall of the guide roller shaft is provided with a silicon carbide wear-resistant layer, which improves the wear resistance of the outer wall of the guide roller shaft.

[0011] As a further technical solution of this utility model, the guide roller shaft is uniformly provided with weight-reducing cavities inside, which reduces the weight of the guide roller shaft and facilitates its rotational movement.

[0012] As a further technical solution of this utility model, the inside of the guide roller shaft is uniformly welded with reinforcing ribs, and both the reinforcing ribs and the guide roller shaft are made of stainless steel.

[0013] As a further technical solution of this utility model, the inner wall of the oil distribution hole is uniformly provided with rubber sealing valves that match the oil distribution ball.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By installing motors, the device optimizes its performance. When the motor starts, it drives the active gear inside the drive housing to rotate. Then, through the action of the transmission belt, it drives the driven gear to rotate, which in turn drives the five guide rollers on the base to rotate. This allows the strip steel products passing between the two symmetrically distributed bases to be subjected to forward transmission force through the movement of the guide rollers when passing through the gaps between the symmetrically arranged guide rollers. This is beneficial for the automated transmission of the strip steel products. Furthermore, the rolling friction between the guide rollers and the strip steel products reduces the impact of frictional resistance compared to the common static guide and limit structure and the sliding friction between the products, further optimizing the guiding and transmission effect.

[0016] By incorporating guide rollers, the top of the guide rollers, near the product, continuously rubs against the oil-distributing balls at the bottom of the oil-distributing cylinder during operation. This causes the oil-distributing balls to move, continuously impacting the rubber sealing valves inside the oil-distributing holes. Consequently, the lubricating oil inside the oil storage box seeps through the oil-distributing holes under gravity and is distributed to the top edge of the guide rollers via the oil-distributing balls. The lubricating oil then flows downwards to the outer surface as the guide rollers move, providing lubrication and protection for the contact surfaces between the guide rollers and the passing strip steel product. This reduces frictional losses during the strip steel cutting and guiding process, thus protecting both the strip steel product and the guide rollers.

[0017] By installing telescopic cylinders, the device optimizes its structure. Users can activate two telescopic cylinders according to the size and specifications of the strip steel products, causing the two bases to move closer or further apart. In conjunction with the sliding limit structure consisting of adjusting sliders and adjusting grooves installed between the bases and the chassis, the stability of the bases is improved. This facilitates flexible adjustment of the spacing of the symmetrically distributed guide rollers according to the products, enhancing applicability. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5 An embodiment of this utility model is provided: a strip steel cutting guide device, including a chassis 4, with bases 1 slidably connected to both sides of the top of the chassis 4, a drive housing 9 fixed to the bottom of the base 1, and a motor 10 installed at the bottom of the drive housing 9.

[0026] The output end of the motor 10 is connected to the drive gear 12. Driven gears 13 are uniformly and movably connected inside the drive housing 9 at both ends of the drive gear 12. A transmission belt 19 is wound between the driven gear 13 and the drive gear 12. Guide rollers 8 connected to the driven gear 13 and the drive gear 12 are installed in sequence inside the base 1.

[0027] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the motor 10 starts and drives the drive gear 12 inside the drive housing 9 to rotate. Then, through the action of the transmission belt 19, it drives the driven gear 13 to rotate, which in turn drives the five guide rollers 8 on the base 1 to rotate. This allows the strip steel products passing between the two symmetrically distributed bases 1 to be subjected to forward transmission force through the movement of the guide rollers 8 when passing through the gaps of the symmetrically arranged guide rollers 8. This is beneficial for the automated transmission of the strip steel products. Furthermore, through the rolling friction between the guide rollers 8 and the strip steel products, compared with the common static guide limiting structure and the sliding friction between the products, the impact of frictional resistance is reduced, and the guiding transmission effect is further optimized.

[0028] An oil storage box 2 is fixed on the base 4 above the guide roller shaft 8. Oil guide cylinders 6 are evenly arranged at the bottom of the oil storage box 2. Oil distribution holes 18 are provided at the bottom of the oil guide cylinders 6. Oil distribution balls 7 that are in contact with the guide roller shaft 8 are movably connected inside the oil distribution holes 18.

[0029] The inner wall of the oiling hole 18 is uniformly provided with rubber sealing valves that match the oiling ball 7;

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, when the guide roller shaft 8 rotates, its top position near the product will continuously rub against the oil distribution ball 7 at the bottom of the oil guide cylinder 6, causing the oil distribution ball 7 to move. This causes the oil distribution ball 7 to continuously impact the rubber sealing valve inside the oil distribution hole 18, thereby causing the lubricating oil inside the oil storage box 2 to continuously seep through the oil distribution hole 18 under the action of gravity. The lubricating oil is then applied to the top edge of the guide roller shaft 8 through the oil distribution ball 7. The lubricating oil then flows downward to the outer surface as the guide roller shaft 8 moves, thus achieving lubrication and protection for the contact surface between the guide roller shaft 8 and the passing strip steel product. This reduces the impact of frictional loss during the strip steel cutting and guiding process, which is beneficial for protecting the strip steel product and the guide roller shaft 8.

[0031] Both ends of the chassis 4 are provided with adjustment grooves 3, and the bottom of the base 1 is fixed with an adjustment slider 11 that is slidably connected to the adjustment grooves 3.

[0032] The outer side wall of the adjusting slider 11 and the inner side wall of the adjusting groove 3 are both uniformly provided with anti-slip limiting teeth.

[0033] Telescopic cylinders 5 are installed at the middle positions on both sides of the chassis 4. The output end of the telescopic cylinder 5 and the outer wall of the base 1 are connected by screws to form a disassembly and installation structure.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, the user can activate two telescopic cylinders 5 according to the size and specifications of the strip steel product, which will drive the two bases 1 to move closer to each other or further away from each other. In conjunction with the sliding limit structure formed by the adjusting slider 11 and the adjusting groove 3 installed between the base 1 and the chassis 4, the stability performance of the base 1 is improved, which makes it easier to flexibly adjust the spacing of the symmetrically distributed guide rollers 8 according to the product, thus enhancing the applicability.

[0035] The top of the oil storage box 2 is provided with a reserved oil filling port 17, and a sealing plug is threaded onto the reserved oil filling port 17;

[0036] The outer wall of the guide roller shaft 8 is provided with a silicon carbide wear-resistant layer 16, which improves the wear resistance of the outer wall of the guide roller shaft 8.

[0037] The guide roller shaft 8 has uniformly arranged weight-reducing cavities 15 inside, which reduces the weight of the guide roller shaft 8 and facilitates its rotational movement.

[0038] The inside of the guide roller shaft 8 is uniformly welded with reinforcing ribs 14, and both the reinforcing ribs 14 and the guide roller shaft 8 are made of stainless steel.

[0039] Working Principle: When in use, with an external power supply, the user first activates two telescopic cylinders 5 according to the size and specifications of the strip steel product. This causes the two bases 1 to move closer together or further apart. Combined with the sliding limit structure formed by the adjusting slider 11 and adjusting groove 3 installed between the base 1 and the chassis 4, the stability of the base 1 is improved. This facilitates flexible adjustment of the spacing of the symmetrically distributed guide rollers 8 according to the product, enhancing applicability. Simultaneously, the motor 10 starts, driving the drive gear 12 inside the drive housing 9 to rotate. Through the transmission belt 19, the driven gear 13 rotates accordingly, thereby driving the five guide rollers 8 on the base 1 to rotate. This allows the strip steel product passing between the two symmetrically distributed bases 1 to be subjected to forward transmission force through the gaps of the symmetrically arranged guide rollers 8, which is beneficial for assisting the production of the strip steel. The automated conveying of the product utilizes the rolling friction between the guide roller shaft 8 and the strip steel product. Compared to the common static guide and limiting structures and the sliding friction between the products, this reduces the impact of frictional resistance and further optimizes the guiding and conveying effect. In addition, when the guide roller shaft 8 rotates, its top position near the product continuously rubs against the oil distribution balls 7 at the bottom of the oil guide cylinder 6, causing the oil distribution balls 7 to move. This causes the oil distribution balls 7 to continuously impact the rubber sealing valve inside the oil distribution hole 18, thereby causing the lubricating oil inside the oil storage box 2 to continuously seep through the oil distribution hole 18 under the action of gravity. The lubricating oil is then applied to the top edge of the guide roller shaft 8 through the oil distribution balls 7. The lubricating oil then flows downward to the outer surface as the guide roller shaft 8 moves, achieving lubrication and protection for the contact surface between the guide roller shaft 8 and the passing strip steel product. This reduces the impact of frictional loss during the strip steel cutting and guiding process, which is beneficial for protecting the strip steel product and the guide roller shaft 8.
