Description

Technical Field

[0001] This utility model belongs to the field of horizontal pressure roller technology, specifically an improved horizontal pressure roller device. Background Technology

[0002] Silicon steel is an essential soft magnetic alloy in the power, electronics, and military industries, and it is also the most widely used soft magnetic material. Normalizing and pickling lines play an irreplaceable role in the production of high-magnetic-induction oriented silicon steel and high-grade non-oriented silicon steel. To obtain non-oriented silicon steel with high magnetic induction and low iron loss, normalizing treatment is often applied in the production of lower grades. High-temperature normalizing pretreatment before rolling annealing can effectively improve the electromagnetic properties of the strip, while also descaling and softening the strip for subsequent cold rolling.

[0003] The normalizing mill mainly consists of an uncoiler, straightener, head cutter, welder, tension rollers, and an exit section coiler. The coiler is located on the exit side of the mill, with its drum axis perpendicular to the mill's centerline. Its base and transmission device are located on the transmission side foundation. The coiler's function is to establish appropriate coiling tension and coil the strip steel into a coil. The horizontal pressure roller is an important auxiliary device for assisting the coiler's coiling. Located on the mill's centerline behind the coiler, its function is to hold down the strip tail and assist the coiler in coiling the strip steel.

[0004] However, traditional horizontal pressure roller structures have the following technical bottlenecks: Existing pressure roller devices mostly use integral bearing housings, which present the following problems for supporting rubber rollers of 840mm and above: The integrally cast bearing housings cannot guarantee the coaxiality of the bearing cavities at both ends of the long rubber roller, resulting in radial runout of the rubber roller generally exceeding 0.1mm. This easily leads to vibration and displacement during high-speed operation. Furthermore, the traditional integrated protective cover has a fixed coverage area and cannot be dynamically adjusted according to working conditions, resulting in a high risk of exposure at the roller shaft end. When the radial runout of the rubber roller exceeds 0.1mm, under high-speed operation, the centrifugal force of the rubber roller will generate additional unbalanced forces due to the runout. These unbalanced forces cause vibration and displacement of the rubber roller during rotation, disrupting the stable contact between the rubber roller and the material being pressed. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes an improved horizontal pressure roller device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an improved horizontal pressure roller device, comprising a support, a base, a rubber roller and a second protective cover. The support is vertically fixed to the base by a bolt and a nut. The rubber roller is arranged laterally on the top of the support and is axially locked by a pressure cap, a second bolt and a washer.

[0007] Preferably, it also includes an upper bearing housing and a lower bearing housing, which are connected vertically by bolts four and five to form a bearing cavity. The upper bearing housing has a flange on its outer side, and the flange is fixed by bolt three and washer two.

[0008] Preferably, a connecting plate is fixed to the side of the base, and a protective cover is connected to the connecting plate by six bolts. The protective cover has an embedded bushing, and the bushing is coaxial with the rubber roller.

[0009] Preferably, the second protective cover is connected to the guide post by bolt seven and washer three, the guide post perpendicularly penetrates the second protective cover, and a stop is provided at its end.

[0010] Preferably, it also includes a bracket, which is hinged to the baffle by a pin and the baffle's unfolding angle is fixed by bolt eight and washer four.

[0011] Preferably, a cylinder is provided on the side of the base, the cylinder is connected to the connecting seat through a copper sleeve, and a stop is provided at the end of the cylinder piston to limit the movement of the second protective cover.

[0012] Preferably, the support side is provided with an oil cup, which is fixed through an independent mounting hole and communicates with the bearing cavity.

[0013] Preferably, the first protective cover and the second protective cover are separate structures. The first protective cover covers the axial end of the rubber roller, and the second protective cover has guide posts that move vertically to achieve dynamic protection.

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

[0015] (1) The upper and lower bearing seats of this utility model are combined with bolts to form a high-precision bearing cavity. With the standard flange interface, the radial runout of the rubber roller can be stably supported for the continuous operation of the 840mm long rubber roller. The vertical bolt fixing structure of the support and the base, combined with the lateral reinforcement design of the connecting plate, improves the overall torsional stiffness and effectively avoids the vibration and displacement of the equipment during high-speed operation.

[0016] (2) The protective cover one and the protective cover two work together. The former fixes the end of the protective rubber roller through a coaxial bushing, while the latter moves vertically along the guide post to achieve dynamic coverage. The protection response time is shortened. The cylinder works with the guide post and the stop block limit mechanism to achieve stroke control accuracy and avoid the cumulative error problem of traditional mechanical limiters. It is suitable for high-precision pressing processes.

[0017] (3) In this utility model, the oil cup is directly connected to the bearing cavity through a special mounting hole, and lubrication can be completed without disassembling the protective cover. The maintenance time is shortened. The static protection of the first protective cover and the dynamic adjustment of the second protective cover form a three-dimensional protective net, reducing the risk of foreign object intrusion and the equipment failure rate.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] Please see Figure 1 - Figure 6 This application provides an improved horizontal pressure roller device, including a support 1, a base 2, a rubber roller 6 and a protective cover 27. The support 1 is vertically fixed to the base 2 by bolts 3 and nuts 4. The rubber roller 6 is arranged laterally on the top of the support 1 and is axially locked by a pressure cap 7, bolts 8 and washers 9.

[0028] It should be noted that the center distance of the rubber rollers 6 is 840mm.

[0029] More specifically, the support 1 is vertically fixed to the base 2 by the tight fit of bolt 3 and nut 4. This connection method is not only stable but also provides a solid foundation for the entire device, ensuring its stability and reliability during operation. The rubber roller 6 is cleverly positioned on top of the support 1 in a transverse arrangement. It is covered by the pressure cap 7 and locked axially by bolt 8 and washer 9. This installation structure ensures the firmness of the rubber roller 6 installation and facilitates subsequent disassembly and maintenance, laying a solid foundation for the normal operation and functionality of the rubber roller device.

[0030] In this embodiment, preferably, it also includes an upper bearing seat 14 and a lower bearing seat 15, which are connected vertically by bolts four 16 and five 17 to form a bearing cavity. A flange 11 is provided on the outer side of the upper bearing seat 14, and the flange 11 is fixed by bolt three 12 and washer two 13.

[0031] More specifically, the key components, upper bearing housing 14 and lower bearing housing 15, are tightly connected by bolts 16 and 17, forming a stable and precise bearing mounting cavity that provides an ideal spatial environment for smooth bearing operation. Simultaneously, an innovative flange 11 is provided on the outer side of the upper bearing housing 14, secured by bolts 12 and washers 13. This design ensures that the flange 11 is firmly connected to the upper bearing housing 14, providing a reliable interface for external transmission connections. This guarantees stable power transmission and effective coordination between the device and other components, enhancing the practicality and versatility of the entire rubber roller assembly.

[0032] In this embodiment, preferably, a connecting plate 5 is fixed to the side of the base 2, and a protective cover 26 is connected to the connecting plate 5 by bolts 23. The protective cover 26 is fitted with a bushing 18, and the bushing 18 is coaxial with the rubber roller 6.

[0033] More specifically, the structure of the connecting plate 5 fixed to the side of the base 2 provides a solid foundation for the installation of subsequent components through the stable connection between the connecting plate 5 and the base 2. The protective cover 26 is cleverly fixed to the connecting plate 5 by bolts 23, forming an integrated protective structure. It is also worth mentioning that the protective cover 26 has an embedded bushing 18, and the bushing 18 is precisely coaxial with the rubber roller 6. This design not only effectively protects the shaft end of the rubber roller 6 from external interference and damage, but also ensures the stability and smoothness of the rubber roller 6 during rotation, extending its service life and providing strong protection for the safety of operators.

[0034] During implementation, when the device is started, the rubber roller 6 rotates smoothly within the bearing cavity. The bearing cavity is rigidly supported by the upper bearing seat 14 and the lower bearing seat 15 connected by bolts. The oil cup 10 continuously supplies lubricating grease to the bearing cavity, reducing the coefficient of friction during operation. The protective cover 26, through the precise coaxial design of the bushing 18, protects the end of the rubber roller without affecting the rotational accuracy. After the flange 11 is connected to the external transmission system, power is efficiently transmitted through this interface.

[0035] Example 2

[0036] In this embodiment, preferably, the second protective cover 27 is connected to the guide post 19 by bolt seven and washer three. The guide post 19 penetrates the second protective cover 27 vertically and has a stop block 24 at its end.

[0037] More specifically, the protective cover 27 is connected to the guide post 19 via bolt 7 and washer 3. The guide post 19 vertically penetrates the protective cover 27 and has a stop 24 at its end. This structural design allows the protective cover 27 to move stably and vertically under the guidance of the guide post 19, while the stop 24 effectively limits the travel of the protective cover 27, preventing excessive movement that could damage the device or cause malfunction. This further enhances the reliability and safety of the rubber roller device during operation and also facilitates precise adjustment of the position of the protective cover 27 according to actual operational needs.

[0038] In this embodiment, preferably, a bracket 25 is also included. The bracket 25 is hinged to the baffle 31 by a pin 30, and the unfolding angle of the baffle 31 is fixed by bolts 32 and washers 33.

[0039] More specifically, the bracket 25 is hinged to the baffle 31 via a pin 30. This connection method gives the baffle 31 a certain range of motion, thus adapting to different operating scenarios and needs. Simultaneously, the baffle 31's unfolding angle is fixed by bolts 32 and washers 33, ensuring its stability after adjustment to a suitable position. This provides auxiliary support and limit protection for the normal operation of the rubber roller device, enhancing the overall stability and ease of operation of the device.

[0040] In this embodiment, preferably, a cylinder 20 is provided on the side of the base 2. The cylinder 20 is connected to the connecting seat 22 through a copper sleeve 21. A stop block 24 is provided at the piston end of the cylinder 20 to limit the movement of the protective cover 27.

[0041] More specifically, a cylinder 20 is provided on the side of the base 2, which is connected to the connecting seat 22 via a copper sleeve 21. This connection method not only ensures the stability of the cylinder 20 installation but also has certain shock absorption and wear resistance properties, extending the service life of the cylinder 20. A stop block 24 is provided at the end of the cylinder piston rod to limit the movement stroke of the protective cover 27, thereby achieving precise control of the position of the protective cover 27, ensuring that its movement under the drive of the cylinder 20 is safe and reliable, avoiding equipment failure caused by excessive stroke, and also improving the automation level and working efficiency of the rubber roller device.

[0042] It should be noted that cylinder 20 has a bore of 160mm and a stroke of 1000mm.

[0043] In this embodiment, preferably, the support 1 is provided with an oil cup 10 on its side. The oil cup 10 is fixed through an independent mounting hole and communicates with the bearing cavity.

[0044] More specifically, the oil cup 10 is fixed through an independent mounting hole, ensuring its stability and independence. It is also connected to the bearing cavity, which allows for convenient and quick supply of lubricating grease to the bearing assembly. This effectively reduces the friction coefficient of the bearing during operation, reduces wear, improves the operating efficiency and reliability of the bearing, lowers the maintenance cost and repair frequency of the equipment, and ensures the long-term stable operation of the rubber roller device.

[0045] In this embodiment, preferably, the first protective cover 26 and the second protective cover 27 are separate structures. The first protective cover 26 covers the axial end of the rubber roller 6, and the second protective cover 27 has a guide post 19 that moves vertically to achieve dynamic protection.

[0046] More specifically, the protective cover 26 and the protective cover 27 adopt a split structure. The protective cover 26 is mainly responsible for covering the axial end of the rubber roller 6, effectively protecting the key parts of the rubber roller 6 and preventing damage from external debris or interference. The protective cover 27 can move vertically along the guide post 19. This dynamic protection design allows the protective cover 27 to flexibly adjust its position according to actual operating needs and the working state of the rubber roller 6, thereby providing all-round protection for the rubber roller 6 and related components under different working conditions. This effectively improves the safety and adaptability of the rubber roller device, ensures its stable operation and efficient work in various complex environments, and further enhances the practicality and market competitiveness of the entire rubber roller device.

[0047] During implementation, when the protection range needs to be adjusted, cylinder 20 drives protective cover 27 to move vertically along guide post 19, and stop block 24 precisely controls the movement stroke; copper sleeve 21 provides wear-resistant guidance during the driving process, and baffle 31 is locked by bolt 32 after unfolding to a predetermined angle through hinge structure; the split structure keeps protective cover 26 fixed, while protective cover 27 can be dynamically adjusted to form a three-dimensional protection system.

[0048] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
