Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a transverse pinch roller device and a transverse pinch roller positioning mechanism thereof. Background Art

[0002] In metallurgical production lines, the pinch rolls in specific areas must have the function of horizontal transverse movement due to process layout requirements, so as to provide operating space for online maintenance and replacement of roll rings. In order to ensure that the pinch roll rings are aligned with the rolling line after transverse movement, a positioning mechanism is required to assist the main equipment in achieving accurate positioning.

[0003] Existing transverse pinch roller device such as Figure 1 As shown, the fixed rail 03 is fixed to the civil engineering foundation by anchor bolts, the main equipment 05 is installed on the mobile seat 02, and the main equipment 05 is driven to move horizontally on the fixed rail 03 by the hydraulic cylinder transverse movement assembly 01. The positioning block 04 is a rectangular square steel, welded on the fixed rail 03, and is positioned by the contact surface between the positioning block 04 and the mobile seat 02, so that the center line of the main roller ring 06 coincides with the rolling center line O, so as to meet the production needs.

[0004] Due to errors in equipment processing and installation, equipment positioning can only be performed during on-site assembly. Since the positioning block 04 is welded to the fixed guide rail 03, the thermal deformation of welding makes it difficult for the contact surface between the positioning block 04 and the movable seat 02 to be completely attached, thus affecting the accuracy of positioning. In addition, since the positioning block 04 is welded to the fixed guide rail 03, the weld is prone to cracking under multiple horizontal impacts of the hydraulic cylinder.

[0005] Therefore, it is necessary to propose a transverse pinch roller device and a transverse pinch roller positioning mechanism thereof to solve at least one of the above problems. Utility Model Content

[0059] The utility model provides a transverse pinch roller device and a transverse pinch roller positioning mechanism thereof, which can improve the positioning accuracy and ensure the reliability of the transverse pinch roller positioning mechanism when in use.

[0060] Please refer to Figure 2 , Figure 3 and Figure 4In the embodiment of the present application, a transverse pinch roller positioning mechanism is provided, which may include: a transverse driving mechanism 1, a movable seat 2, a fixed guide rail 3, an adjustable positioning block 8, a stopper 9 and an adjustment assembly 10, wherein the transverse driving mechanism 1 is used to drive the movable seat 2 to move transversely on the fixed guide rail 3; a first matching inclined surface 21 is provided at the end of the movable seat 2; the stopper 9 is connected to the fixed guide rail 3; the adjustable positioning block 8 is provided between the first matching inclined surface 21 and the stopper 9, and the adjustable The positioning block 8 includes a first part 81 for fixing on the fixed guide rail 3 and a second part 82 which is at a predetermined angle with the first part 81, the second part 82 is provided with a second mating bevel 822 which is mating with the first mating bevel 21, and the first mating bevel 21 and the second mating bevel 822 have the same angle with the horizontal plane; the second part 82 is also provided with abutting surface 823 for abutting against the stopper 9; the adjustment assembly 10 is detachably arranged between the fixed guide rail 3 and the first part 81.

[0061] In the implementation manner of the present application, the transverse pinch roller positioning mechanism mainly includes: a transverse driving mechanism 1, a movable seat 2, a fixed guide rail 3, an adjustable positioning block 8, a stopper 9 and an adjustment assembly 10 and other components.

[0062] In the embodiment of the present application, the movable seat 2 is positioned with the adjustable positioning block 8 via an inclined surface. When the transverse pinch roller positioning mechanism is positioned via the inclined surfaces of the movable seat 2 and the adjustable positioning block 8, the vertical downward force component can stabilize the movable seat 2 when the inclined surfaces are in contact.

[0063] Please refer to Figure 5 and Figure 6 Specifically, the adjustable positioning block 8 may include a first portion 81 for fixing on the fixed guide rail 3 and a second portion 82 which is at a predetermined angle to the first portion 81. The first portion 81 and the second portion 82 may be at an angle of 90°, and the adjustable positioning block 8 may be an L-shaped structure as a whole.

[0064] The first portion 81 is a rectangular block with a predetermined thickness, and the second portion 82 is a right-angled trapezoidal block with a predetermined thickness.

[0065] Specifically, the first part 81 is located on a horizontal plane and is fixed on the fixed guide rail 3. The second part 82 is located on a vertical plane and is provided with a vertical end face and an inclined surface on the left and right sides of the second part 82 along the horizontal direction, respectively. The inclined surface is used as the first matching inclined surface 21 of the movable seat 2, and the first matching inclined surface 21 matches with the second matching inclined surface 822. The angle between the second matching inclined surface 822 and the horizontal plane is θ1.

[0066] The end of the movable seat 2 is provided with an inclined surface, which is a first matching inclined surface 21 for matching with the inclined surface of the adjustable positioning block 8. The angle between the first matching inclined surface 21 and the horizontal plane is θ2, and θ1=θ2.

[0067] In a specific embodiment, the angles between the first mating bevel 21 and the second mating bevel 822 and the horizontal plane are both 45°. When the angles between the first mating bevel 21 and the second mating bevel 822 and the horizontal plane are 45°, the adjustment capability of the horizontal direction of the transverse pinch roller positioning mechanism is the same as the adjustment range in the vertical direction. For example, when the adjustment range of the adjustment component is 10 mm, the adjustment capability of the transverse pinch roller positioning mechanism in the horizontal direction is also 10 mm.

[0068] In this embodiment, the fixed guide rails 3 can be arranged in double rows and fixed on the civil engineering foundation by anchor bolts.

[0069] The movable seat 2 can be driven by the transverse driving mechanism 1 to move transversely on the fixed guide rail 3. The driving source of the transverse driving mechanism 1 can be in the form of hydraulic pressure. When the transverse driving mechanism 1 is in the form of hydraulic pressure, it can include a hydraulic cylinder transverse component.

[0070] Of course, the specific setting method of the transverse driving mechanism 1 can also be other methods and is not limited to the above description. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0071] In this embodiment, the stopper 9 is connected to the fixed guide rail 3, so as to stop one side of the adjustable positioning block 8. Specifically, the stopper 9 can abut against the abutting surface 823 of the second part 82 of the adjustable positioning block 8, so as to provide a stopping force to the abutting surface 823 along the horizontal direction.

[0072] Specifically, the stopper 9 can be connected to the fixed guide rail 3 in a detachable manner. The detachable manner can be different according to the specific form of the stopper 9. For example, the detachable manner can be a hole-shaft connection.

[0073] In a specific embodiment, the stop member 9 is a cylindrical pin, which includes a connecting portion extending into the fixed guide rail 3 and a stop portion extending out of the fixed guide rail 3 , the stop portion is formed with a stop plane 91 , and the abutment surface 823 is in contact with the stop plane 91 .

[0074] In this embodiment, the stopper 9 can be a cylindrical pin, and the corresponding fixed guide rail 3 is provided with a circular hole for installing the cylindrical pin. The cylindrical pin includes a connecting portion and a stopper, wherein the connecting portion is fixed in the circular hole of the fixed guide rail 3, and the stopper extending out of the fixed guide rail 3 has a part of the arc surface processed into a plane, which serves as the stopper plane 91 and the abutment surface 823 ( Figure 5 The horizontal impact force in the transverse pinch roller positioning mechanism is borne by the stopper 9 (e.g., a cylindrical pin), which can overcome the problem of weld cracking of the welding positioning block in the prior art. The stopper 9 is a low-cost and easy-to-replace component. After a period of use, it can be easily replaced at a low cost, thereby reducing the use and replacement costs of the transverse pinch roller positioning mechanism.

[0075] In this embodiment, the adjustment component 10 is detachably disposed between the fixed guide rail 3 and the first portion 81. When the adjustment component 10 is detachably disposed between the fixed guide rail 3 and the first portion 81 of the adjustable positioning block 8, the position of the center line of the main roller ring 6 can be adjusted by changing the thickness of the adjustment component 10, thereby solving the problem of poor accuracy of the welding positioning block.

[0076] Specifically, the detachable manner may be a threaded connection. Of course, the specific detachable setting manner may also be other manners, and is not limited to the above description. A person skilled in the art may make other changes under the inspiration of the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they shall be included in the protection scope of this application.

[0077] When the detachable manner is a threaded connection, the transverse pinch roller positioning mechanism may further include at least one bolt 7 , and the adjustment assembly 10 is connected between the fixed guide rail 3 and the first part 81 via the bolt 7 .

[0078] like Figure 7 As shown, in a specific embodiment, the adjustment assembly 10 may include a plurality of adjustment gaskets, and the adjustment gasket includes a plate body with a predetermined thickness, and the plate body is provided with an avoidance groove 101 that cooperates with the bolt 7.

[0079] In this embodiment, an adjusting gasket is provided between the adjustable positioning block 8 and the fixed guide rail 3 , and the adjustable positioning block 8 and the adjusting gasket are installed above the fixed guide rail 3 by means of bolts 7 .

[0080] Please refer to Figure 3 , Figure 5 and Figure 7The number of the bolts 7 is the same as the number of the avoidance grooves 101, or at least the number of the avoidance grooves 101 is not less than the number of the bolts 7, so as to ensure that the bolts 7 can pass through the avoidance grooves 101 and pass through the adjustment gasket and be pressed on the adjustment gasket. Specifically, the number of the bolts 7 and the avoidance grooves 101 are both two. When the number of the bolts 7 and the avoidance grooves 101 are both two, on the one hand, the reliability of the connection can be ensured, and on the other hand, when the two bolts 7 are arranged along the moving direction of the moving seat 2, it is sufficient to ensure the stability of the connection position.

[0081] To ensure the normal operation of the production line, the center line of the main roller ring 6 must coincide with the rolling center line O. However, due to the accumulation of errors in manufacturing, assembly, on-site installation, etc., during actual on-site installation, when the first mating bevel 21 of the movable seat 2 and the second mating bevel 822 of the adjustable positioning block 8 coincide, the center line of the main roller ring 6 may not completely coincide with the rolling center line O. At this time, the adjustment gaskets can be added or subtracted as needed, and the thickness of the adjustment gaskets can be changed to make the center line of the main roller ring 6 completely coincide with the rolling center line O.

[0082] For example, in one scenario, if the thickness of the adjustment gasket needs to be increased to Figure 3 In the middle and high position H, the second matching inclined surface 822 of the adjustable positioning block 8 moves to the left, and the moving seat 2 drives the main roller ring 6 to move to the left together; in another scenario, if the thickness of the adjustment gasket needs to be reduced to h Figure 3 In the middle and low position L, the inclined surface of the adjustable positioning block 8 moves to the right, and the moving seat 2 drives the main roller ring 6 to move to the right together. Overall, the position of the main roller ring 6 can be adjusted by the first matching inclined surface 21 of the moving seat 2 and the second matching inclined surface 822 of the adjustable positioning block 8, so that the center line of the main roller ring 6 completely coincides with the rolling center line O.

[0083] The transverse shifting pinch roller positioning mechanism provided in the embodiment of the present application: when installing the equipment, first move the center line of the main roller ring 6 to a position that coincides with the rolling center line O and fix it, fit the first mating inclined surface 21 of the movable seat 2 with the second mating inclined surface 822 of the adjustable positioning block 8, and at the same time, fit the stop plane 91 of the stop member 9 with the abutment surface 823 of the adjustable positioning block 8, measure the distance h between the adjustable positioning block 8 and the fixed guide rail 3, insert an adjustment gasket of corresponding thickness, and then tighten and fix it with bolts 7. At this time, the abutment surface 823 of the adjustable positioning block 8 can accurately position the transverse shifting equipment.

[0084] When the main equipment 5 needs to be moved laterally for reasons such as maintenance, the hydraulic cylinder transverse movement assembly drives the main equipment 5 to move backward by pulling the moving seat 2. After the maintenance is completed, the hydraulic cylinder transverse movement assembly pushes the moving seat 2. When the first mating inclined surface 21 of the moving seat 2 is in contact with the second mating inclined surface 822 of the adjustable positioning block 8, the main roller ring 6 is in the accurate position, and the operation is simple and precise.

[0085] The transverse pinch roller positioning mechanism provided in the embodiment of the present application adopts an adjustable positioning mechanism, which adjusts the position of the center line of the main roller ring 6 by increasing or decreasing the thickness of the adjustment gasket, thereby solving the problem of poor accuracy of the welding positioning block.

[0086] The horizontal impact force of the transverse pinch roller positioning mechanism is borne by the detachable stopper 9, thereby solving the problem of cracking of the weld of the welding positioning block.

[0087] The transverse pinch roller positioning mechanism is positioned by the movable seat 2 and the inclined surface of the adjustable positioning block 8. When the inclined surfaces are in contact, the horizontal downward force has a stabilizing effect on the movable seat 2, and the overall reliability during operation is high.

[0088] like Figure 2 As shown, in the embodiment of the present application, a transverse pinch roller device is also provided, and the transverse pinch roller device mainly includes the transverse pinch roller positioning mechanism mentioned above. In addition, as Figure 2 As shown, the transverse pinch roller device may also include a main device 5 and a main roller ring 6. The transverse pinch roller device can achieve the technical effect achieved by the transverse pinch roller positioning mechanism implementation scheme by setting the transverse pinch roller positioning mechanism. For details, please refer to the specific description of the above implementation scheme, and this application will not repeat it here.

[0089] It should be noted that, in the description of this application, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0090] The above-mentioned various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0091] The above are only a few embodiments of the present invention. Although the embodiments disclosed by the present invention are as above, the contents are only embodiments adopted for facilitating the understanding of the present invention and are not used to limit the present invention. Any technician in the technical field to which the present invention belongs can make any modification and change in the form and details of the implementation without departing from the spirit and scope disclosed by the present invention, but the scope of patent protection of the present invention shall still be subject to the scope defined by the attached claims.
