Description

Technical Field

[0001] This utility model relates to the field of supporting steel roller technology, specifically a supporting steel roller with a multi-layer fastening installation mechanism. Background Technology

[0002] Support rolls play a crucial role in rolling mills. They support the work rolls or intermediate rolls to prevent deflection and deformation during rolling, which could affect the shape and quality of the sheet metal. These rolls ensure the work roll's accuracy and the product's dimensional accuracy by increasing its rigidity and directly or indirectly bearing the rolling load. Common materials for support rolls include 9Cr2Mo, 70Cr3Mo series, 50Cr4MoV, and 45Cr5MoV, chosen for their excellent comprehensive mechanical properties and thermal shock resistance. With technological advancements, the 70Cr3Mo series has become the preferred material for support rolls. During rolling, support rolls endure significant contact stress, impact, and thermal cycling stress, thus requiring stringent requirements for their comprehensive mechanical properties and thermal shock resistance. The quality of the support rolls directly affects the output and quality of the rolled sheet. As rolling mill design requirements increase and rolling conditions change, support roll materials are continuously improved to accommodate deeper hardened layers and enhance wear resistance and fatigue resistance. In the manufacturing process of support rolls, heat treatment is particularly critical, including quenching and tempering, which enable the rolls to obtain the required hardness and wear resistance. Overall, support rolls are an indispensable component in the rolling process, and their material and heat treatment processes have a decisive influence on their performance. Moreover, with technological advancements, the materials and designs of support rolls are constantly being optimized to meet higher industrial production requirements.

[0003] According to publication number CN220277871U, the stainless steel support includes a roller body and a base. The roller body is equipped with a cooling channel and is connected to the base. A cleaning component is installed on the roller body and is sleeved on the roller body. The cleaning component includes an electric slide, a cleaning sleeve, and a motor. The motor rotation realizes the linear displacement of the slider on the electric slide, and the slider drives the cleaning sleeve to move, thereby cleaning and cooling the surface of the roller body.

[0004] The above technology utilizes a base and cleaning components to clean and cool the surface of the steel roller. However, the steel roller cannot be easily installed during use, nor can the connection structure of the steel roller itself be kept stable during use.

[0005] Therefore, in view of this, we have studied and improved the existing shortcomings and proposed a support steel roller with a multi-layer fastening installation mechanism. Utility Model Content

[0006] The purpose of this invention is to provide a support steel roller with a multi-layer fastening installation mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a support steel roller with a multi-layer fastening installation mechanism, comprising: a roller body, receiving shafts on both sides of the roller body, umbrella-shaped pieces arranged in a ring at both ends of the outer side of the roller body, a first connecting piece arranged at the bottom end of the inner side of the umbrella-shaped pieces, a second connecting piece rotatably connected to one end of the first connecting piece, and a pressing block arranged at the top end of the second connecting piece;

[0008] An auxiliary structure is provided in a ring on the outer surface of the receiving shaft.

[0009] Furthermore, the first connecting piece and the second connecting piece are of the same length, which facilitates the installation of the first connecting piece and the second connecting piece.

[0010] Furthermore, a small rotating shaft is provided laterally through the connection between the first connecting piece and the second connecting piece to facilitate rotational movement between the first connecting piece and the second connecting piece.

[0011] Furthermore, the umbrella pack piece is L-shaped, and the area of ​​the upper surface of the pressure block is smaller than the area of ​​the bottom surface of the pressure block, which facilitates the installation of the umbrella pack piece and makes it easier for the pressure block to be placed at the bottom of the umbrella pack piece.

[0012] Furthermore, the auxiliary structure includes a stop block, a push rod, a rotating plate, a slitting plate, a pull rod, and a toothed block. A stop block is arranged in a ring around the outer side of the receiving shaft. The lower end of the outer surface of the stop block is provided with a long strip-shaped groove. A toothed block is provided inside the groove at the lower end of the outer surface of the stop block. Multiple sawtooth-shaped protrusions are provided at the bottom end of the toothed block. A pull rod is provided at the upper end of the front side of the toothed block. A slitting plate is provided at the front end of the pull rod. Push rods are provided at the lower ends of both ends of the slitting plate. A rotating plate is rotatably provided at the upper ends of both ends of the slitting plate. The rotating plate is composed of a long fixed strip and a rotating shaft, which allows the rotating shaft part of the rotating plate to drive the slitting plate to rotate slightly.

[0013] Furthermore, the connecting part where the push rod and the pull rod overlap is provided with a pivot shaft running horizontally through it, so that the parts connecting the push rod and the pull rod can use the same pivot shaft, allowing the push rod and the pull rod to rotate simultaneously.

[0014] Furthermore, the elongated portion of the rotating plate is fixedly connected to the abutment block, which facilitates fixing the position of the rotating plate.

[0015] Furthermore, the inner angle of the push rod is an obtuse angle, which makes it easy for the push rod to contact the surface of external equipment.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. When this utility model is installed through both ends of the roller body, the connecting part of the external adapter first squeezes the umbrella-shaped pieces on the outer side of both ends of the roller body. When the umbrella-shaped pieces are squeezed, they contract towards the outside of the roller body, and the pressing block on the inner side of the umbrella-shaped pieces deforms under pressure. At the same time, the second connecting piece and the first connecting piece are set to rotate in accordance with the changes of the umbrella-shaped pieces and the pressing block. In this way, when both ends of the roller body are completely locked by the external adapter, the reaction force of the pressing block pushes up the umbrella-shaped pieces, so that the umbrella-shaped pieces cannot fully contract downward. At this time, the umbrella-shaped pieces will press against the roller body and the external adapter, thereby increasing the tightness of the connection between the roller body and the external adapter.

[0018] 2. In this utility model, when the receiving shaft is connected to an external device, the surface of the external device first abuts against the push rod and rotates backward. The push rod drives the pull rod to rotate forward. At the same time, the rotating shaft of the sliding plate and the rotating plate rotate in coordination with the rotation of the pull rod. In this way, when the receiving shaft is connected to the external device, the push rod is forced to rotate the pull rod forward. The pull rod drives the toothed block to rotate out from the inside of the abutment block and abut against the receiving part of the external device, which increases the stability of the connection between the receiving shaft and the external device.

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

[0026] like Figures 1-5 As shown, a support steel roller with a multi-layer fastening installation mechanism includes: a roller body 1, receiving shafts 4 on both sides of the roller body 1, umbrella-shaped pieces 6 arranged in a ring at both ends of the outer side of the roller body 1, a first connecting piece 3 arranged at the bottom end of the inner side of the umbrella-shaped piece 6, a second connecting piece 5 rotatably connected to one end of the first connecting piece 3, and a pressing block 7 arranged at the top end of the second connecting piece 5.

[0027] An auxiliary structure 2 is provided in a ring on the outer surface of the receiving shaft 4.

[0028] The rest, since the umbrella sheet 6 is annularly arranged on the outer sides of both ends of the roller body 1, and the pressing block 7 is located at the bottom end of the umbrella sheet 6, when the umbrella sheet 6 is squeezed, the pressing block 7 deforms along with the compression of the umbrella sheet 6. At the same time, the first connecting piece 3 and the second connecting piece 5 rotate and adjust along with the pressing block 7. The first connecting piece 3 and the second connecting piece 5 are responsible for connecting the pressing block 7 and the umbrella sheet 6, thereby preventing the pressing block 7 from being dislodged from the inner side of the umbrella sheet 6 due to excessive force. The user can place the pressing block 7 at the bottom end of the umbrella sheet 6. Both sides are provided with a first connecting piece 3, a second connecting piece 5, and a pressing block 7, etc., to reduce the amplitude generated when the umbrella piece 6 is squeezed. The user can also change the shape of the pressing block 7. The pressing block 7 can be a flat structure or a circular structure, so that the pressing block 7 can better fit the bottom structure of the umbrella piece 6. The user can also reduce the volume of the umbrella piece 6 and other components, and increase the number of umbrella pieces 6, thereby improving the tightness when the roller body 1 is connected to the external equipment.

[0029] This has resulted in the following effects and novel technologies:

[0030] Its innovative structure enhances fastening stability and improves the connection stability between the roller body 1 and external equipment. The umbrella-shaped sheet 6 is annularly positioned on the outer sides of both ends of the roller body 1, and the pressure block 7 is located at the bottom of the umbrella-shaped sheet 6. When the umbrella-shaped sheet 6 is compressed, the pressure block 7 deforms, strengthening the fastening connection. The rotating connection design between the first connecting piece 3 and the second connecting piece 5 allows for adjustment when the pressure block 7 deforms, dispersing pressure and reducing localized stress. This design also prevents the pressure block 7 from detaching from the inner side of the umbrella-shaped sheet 6 due to excessive force, ensuring structural integrity and reliability. The first connecting piece 3, the second connecting piece 5, and the pressure block 7 set on both sides of the bottom end help to reduce the extrusion amplitude, reduce vibration, and improve the running stability of the roller body 1. Users can change the shape of the pressure block 7 as needed to improve the fastening effect. At the same time, the volume of the umbrella-shaped piece 6 can be reduced and its number increased to improve the tightness between the roller body 1 and external equipment. This support steel roller design enhances the stability and reliability of the roller body 1 through the innovation of the multi-layer fastening installation mechanism, increases the adaptability and personalization of the structure, and provides a new fastening solution for support rollers in rolling mills.

[0031] like Figures 1-5 As shown, a support steel roller with a multi-layer fastening installation mechanism includes an auxiliary structure 2 comprising a stop block 21, a push rod 22, a rotating plate 23, a slitting plate 24, a pull rod 25, and a toothed block 26. A stop block 21 is annularly arranged on the outer side of the receiving shaft 4. The lower end of the outer surface of the stop block 21 has a long, narrow groove. A toothed block 26 is arranged inside the groove at the lower end of the outer surface of the stop block 21. Multiple serrated protrusions are arranged at the bottom end of the toothed block 26. A pull rod 25 is arranged at the upper end of the front of the toothed block 26. A slitting plate 24 is arranged at the front end of the pull rod 25. Push rods 22 are arranged at the lower ends of both ends of the slitting plate 24. A rotating plate 23 is rotatably arranged at the upper ends of both ends of the slitting plate 24. The rotating plate 23 is composed of a long fixing strip and a rotating shaft.

[0032] As for the rest, when the receiving shaft 4 is connected to the receiving part of the external equipment, the push rod 22 is squeezed by the receiving part of the external equipment and rotates backward. The push rod 22 drives the pull rod 25 to rotate, and the rotating plate 23 and the sliding plate 24 cooperate with the push rod 22 and the pull rod 25 to rotate. The sliding plate 24 can also rotate slightly with the cooperation of the rotating shaft at the front end of the rotating plate 23. After the pull rod 25 rotates, it drives the toothed block 26 to move out from the inside of the abutment block 21. Thus, the toothed block 26 is stuck or abuts against the surface of the receiving part of the external equipment. The user can replace the toothed block 26 with a wedge-shaped object to adapt to the surface of the receiving part of the external equipment with different structures.

[0033] This has resulted in the following effects and novel technologies:

[0034] This design of the support steel roller, through the innovation of auxiliary structure 2, achieves rapid fastening and adaptability when connected to external equipment. When the push rod 22 in auxiliary structure 2 is squeezed by external equipment, it rotates, driving the pull rod 25 and the rotating plate 23 to rotate in conjunction with the slitting plate 24, achieving rapid fastening. The toothed block 26 can be moved out from the inside of the abutment block 21 and is locked or pressed against the surface of the external equipment receiving point, providing strong fixing force. It can also be replaced with a wedge structure as needed to adapt to the surface of the external equipment receiving point with different structures. The slitting plate 24 can rotate slightly with the cooperation of the rotating shaft at the front end of the rotating plate 23, increasing the structural flexibility and adaptability to different installation angles. The entire auxiliary structure 2 is simple and easy to operate. It only requires simple squeezing and releasing actions to achieve rapid connection and separation, improving installation efficiency and work efficiency. The slot design and sawtooth protrusion of the toothed block 26 enhance the connection safety and prevent accidental detachment under high pressure or vibration. This support steel roller design improves the speed and adaptability of connection with external equipment, enhances the ease of operation and installation safety, and provides a new fastening solution for support rollers in rolling mills.

[0035] Working principle: When using the support steel roller with a multi-layer fastening installation mechanism, first align the receiving shaft 4 with the receiving interface of the external equipment. When the push rod 22 touches the outside of the receiving interface of the external equipment, the push rod 22 rotates backward. The push rod 22 drives the pull rod 25 to rotate forward on the outside of the slitting plate 24, and the rotating plate 23 helps the slitting plate 24 to make a small-amplitude rotation adjustment. When the pull rod 25 rotates forward, the pull rod 25 drives the toothed block 26 to move out from the inside of the abutment block 21, and the toothed block 26 is locked or abutted at the receiving port of the external equipment. When the roller body 1 needs to be assembled with the external equipment, the umbrella-shaped plates 6 on both sides of the roller body 1 are the first to be affected by the external equipment. When the umbrella-shaped sheet 6 is compressed, the pressure block 7 deforms as the umbrella-shaped sheet 6 compresses downwards. At the same time, the first connecting piece 3 and the second connecting piece 5 at one end of the pressure block 7 help to connect the pressure block 7 with the umbrella-shaped sheet 6, preventing the pressure block 7 from being dislodged from the inside of the umbrella-shaped sheet 6 due to excessive force. When the umbrella-shaped sheets 6 at both ends of the roller body 1 shrink to a certain extent, the pressure block 7 on the inside of the umbrella-shaped sheet 6 no longer deforms. At this time, the external structure of the pressure block 7, which is deformed by compression, gives the umbrella-shaped sheet 6 a reaction force, and the umbrella-shaped sheet 6 will react on the connection surface of the external equipment. This is the working principle of the support steel roller with a multi-layer fastening installation mechanism.
