Description

Technical Field

[0001] This utility model relates to the field of rolling mill equipment technology, specifically to a steel transfer device for a transverse rolling mill. Background Technology

[0002] In a tandem rolling mill, the rolls are arranged along the width of the production line, meaning the roll axes are perpendicular to the direction of material movement. This arrangement allows material to be rolled in the width direction, making it suitable for producing wider plates or strips. It is commonly used in hot rolling processes and can handle larger raw materials. Tandem rolling mills can achieve multi-pass continuous rolling, controlling the thickness and width of the product by adjusting the spacing between different rolls. This layout improves production efficiency and product quality consistency.

[0003] Currently, the main products produced by the transverse three-roll mill are round bars and square bars of various specifications. Each specification has a corresponding pass system. The billets before rolling are mostly large square billets. The mill is mainly used to squeeze and deform the billets to finally produce finished products of specific specifications. During rolling, the workpieces are put into the passes in descending order on the transverse mill. The traditional method is for rolling workers to manually pull and move the materials using tools. This method not only affects the efficiency of the operation, but also increases the labor intensity and safety risks of the employees.

[0004] In view of the above, it is necessary to propose a steel transfer device for a transverse rolling mill to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects existing in the prior art and provide a steel transfer device for a transverse rolling mill.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A steel transfer device for a transverse rolling mill includes multiple material conveying channels of the rolling mill, and a steel transfer device is provided between two adjacent material conveying channels. The material conveying channels include an upper rolling channel and a lower rolling channel. The steel transfer device includes a steel transfer platform disposed between two rolling channels. A steel pusher head is provided on the steel transfer platform, which moves back and forth or circulates between the two rolling channels. The steel pusher head includes a block-shaped protrusion protruding from the flat surface of the steel transfer platform.

[0007] The upper rolling channel is equipped with a feeding device, which transports the billet on the upper rolling channel to the steel transfer platform. At this time, the steel pusher head is located on the side of the billet away from the lower rolling channel. The steel pusher head presses against the side of the billet and pushes the billet to move towards the lower rolling channel.

[0008] Furthermore, the feeding device includes a feeding ramp, and the upper rolling channel is positioned above the upper surface of the steel transfer platform, so that the billet slides onto the steel transfer platform via the feeding ramp.

[0009] Furthermore, the high point side of the feeding ramp is connected to the horizontal plane of the upper rolling channel, and the low point side extends to the upper plane of the steel transfer platform; the feeding device also includes a steel tilting bracket, which has a horizontal state and a tilted state.

[0010] When the steel-turning support is in a horizontal state, it forms a plane parallel to the horizontal plane of the upper rolling channel, and the upper plane of the steel-turning support does not exceed the horizontal plane of the upper rolling channel;

[0011] When the steel-turning support is in the tilted state, it forms an upward-extending inclined surface at the high point of the feeding slope, making the steel-turning support a continuation of the feeding slope. At this time, the steel-turning support protrudes from the horizontal surface of the upper rolling channel.

[0012] Furthermore, the feeding device also includes a steel-tilting cylinder, which drives the steel-tilting bracket to switch between a horizontal state and a tilted state.

[0013] Furthermore, the steel transfer device also includes a steel transfer chain installed inside the steel transfer platform, wherein the conveying direction of the steel transfer chain is parallel to the line connecting the upper rolling channel and the lower rolling channel.

[0014] Furthermore, the steel-moving platform is equipped with a rotating transmission sprocket inside, and a steel-moving chain is wound around the transmission sprockets at both ends of the steel-moving platform. A steel-pushing head is fixedly connected to the steel-moving chain. It also includes a steel-moving motor, which drives the steel-moving chain to rotate.

[0015] Furthermore, the moving steel chain is provided with at least one pushing head.

[0016] Furthermore, the upper surface of the feeding ramp and / or the steel-turning bracket is provided with rollers, and the rollers are arranged in several groups at intervals along the sliding direction of the feeding ramp.

[0017] The advantages and beneficial effects of this utility model are as follows: The steel transfer device for a transverse rolling mill uses a steel-turning bracket to flip and lift the steel billet moved to its upper side, allowing the billet to slide down the feeding ramp onto the steel transfer platform. A pusher head then pushes the billet into the next rolling channel, facilitating the next round of rolling. This device is easily installed at bends in the rolling channel, effectively reducing the space occupied in the length of the plant and allowing the rolling channel to expand in width, thus facilitating efficient use of the plant space. Furthermore, it avoids the need for manual traction of the billet between rolling channels, effectively reducing the workload and risks for employees. Attached Figure Description

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0023] Example 1:

[0024] A steel transfer device for a transverse rolling mill, such as Figure 1-3 As shown, the mill includes multiple material conveying channels, including an upper rolling channel 2 and a lower rolling channel 14. A steel transfer device 1 is provided between two adjacent material conveying channels, such as... Figure 1 As shown, the two conveying channels can be parallel to each other. The steel transfer device 1 is set at the end of the conveying channel, so that the channel for conveying billets turns around at that point, avoiding the design of a straight conveying channel, reducing the length of the plant and improving the utilization of the plant width. In addition, this device can automatically transfer the billet between the two conveying channels, avoiding manual transfer, reducing the intensity of manual labor, and effectively ensuring safety.

[0025] like Figure 1 As shown, the steel transfer device 1 includes a steel transfer platform 3 disposed between two rolling channels. The steel transfer platform 3 is provided with a steel pusher head 4 that moves back and forth or circulates between the two rolling channels. The steel pusher head 4 includes a block-shaped protrusion protruding from the upper plane of the steel transfer platform 3. It can be understood that this embodiment does not set the structure of the surface of the steel transfer platform 3. It can be that the surface has a structure to support the rolling of the steel billet, thereby reducing the frictional resistance when the steel billet moves. The steel pusher head 4 can be disposed between the rolling structure supporting the steel billet to apply a pushing force to the steel billet.

[0026] Specifically, such as Figure 2As shown, the steel transfer device 1 also includes a steel transfer chain 9 disposed inside the steel transfer platform 3. The conveying direction of the steel transfer chain 9 is parallel to the line connecting the upper rolling channel 2 and the lower rolling channel 14. Since the conveying direction of the steel transfer chain 9 is parallel to the line connecting the two rolling channels, the pusher head 4 can be controlled to move along the direction of this line, thereby pushing the billet on the steel transfer platform 3 from the upper rolling channel 2 to the lower rolling channel 14.

[0027] Furthermore, the steel-moving platform 3 is internally equipped with a transmission sprocket 10 for rotation, such as... Figure 2 As shown, a steel-moving chain 9 is wound around the transmission sprockets 10 at both ends of the steel-moving platform 3. It can be understood that... Figure 2 The diagram only shows the structure of one steel moving chain 9, but several steel moving chains 9 can be arranged in parallel on the steel moving platform 3, and a steel pushing head 4 is fixedly connected to the steel moving chain 9; the steel pushing head 4 on each steel moving chain 9 is in the same position, so when the billet falls onto the steel moving platform 3, the operation of the steel moving chain 9 controls the movement of the steel pushing head 4, thereby pushing the billet to move;

[0028] It also includes a steel transfer motor 11, which drives the steel transfer chain 9 to operate. The steel transfer motor 11 serves as the driving mechanism for the steel transfer chain 9. It drives the transmission sprocket 10 at one end through the transmission chain 12, thereby enabling it to act as a drive sprocket to control the operation of the steel transfer chain 9. By controlling the forward and reverse rotation of the steel transfer motor 11, the steel pusher head 4 can be made to move back and forth or circulate between the two rolling channels. The back and forth movement can be understood as the steel pusher head 4 moving from the end of the upper rolling channel 2 to the end of the lower rolling channel 14, and then the steel transfer motor 11 rotating in the reverse direction to control the steel pusher head 4 to return to the end of the upper rolling channel 2 for the next billet push.

[0029] The cyclic movement can be understood as follows: the steel-moving motor 11 rotates in a fixed direction, and the direction of operation of the steel-moving chain 9 is also fixed. Preferably, the upper side of the steel-moving chain 9 is the pushing stroke, which moves from the upper rolling channel 2 to the lower rolling channel 14; the lower side of the steel-moving chain 9 is the return stroke, which moves from the lower rolling channel 14 to the upper rolling channel 2; thus forming a circular operation. At least one pushing head 4 is provided on the steel-moving chain 9, such as... Figure 2 , 3 As shown, two push heads 4 are set on the moving steel chain 9. During the movement of the moving steel chain 9, the two push heads 4 alternately push the billet to the next rolling channel 14.

[0030] The upper rolling channel 2 is equipped with a feeding device 5, which transports the billet on the upper rolling channel 2 to the steel transfer platform 3. At this time, the steel pusher 4 is located on the side of the billet away from the lower rolling channel 14. The steel pusher 4 presses against the side of the billet and pushes the billet to move towards the lower rolling channel 14.

[0031] Specifically, such as Figure 2 As shown, the feeding device 5 includes a feeding ramp 6. The upper rolling channel 2 is positioned higher than the upper surface of the steel transfer platform 3, allowing the billet to slide onto the steel transfer platform 3 via the feeding ramp 6. When the billet moves to the end of the upper rolling channel 2, moving the billet to the feeding ramp 6 allows it to fall onto the steel transfer platform 3 along the ramp, thus achieving the transfer of the billet.

[0032] The high point side of the feeding ramp 6 is connected to the horizontal plane of the upper rolling channel 2, and the low point side extends to the upper plane of the steel transfer platform 3; the feeding device 5 also includes a steel tilting bracket 7, which has a horizontal state and a tilted state; when the billet moves to the end of the upper rolling channel 2, the billet slides down along the steel tilting bracket 7 and the feeding ramp 6 by changing the state of the steel tilting bracket 7.

[0033] Specifically, such as Figure 2 As shown, when the steel-turning support 7 is in a horizontal state, it forms a plane parallel to the horizontal plane of the upper rolling channel 2, and the upper plane of the steel-turning support 7 does not exceed the horizontal plane of the upper rolling channel 2; as Figure 3 As shown, when the steel-turning support 7 is in the tilted state, it forms an upward-extending inclined surface at the high point of the feeding ramp 6, making the steel-turning support 7 a continuation of the feeding ramp 6. At this time, the steel-turning support 7 protrudes from the horizontal plane of the upper rolling channel 2. The feeding device 5 also includes a steel-turning cylinder 8, which drives the steel-turning support 7 to switch between the horizontal state and the tilted state.

[0034] like Figure 3 As shown, rollers 13 are provided on the upper surface of the feeding ramp 6 and / or the steel-turning bracket 7, and several sets of rollers 13 are spaced apart along the sliding direction of the feeding ramp 6. Providing rollers 13 on the surface allows the billet to move more smoothly and accelerates the billet transfer speed.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
