Abstract
Description
Technical Field
[0001] This application relates to the field of gantry shearing machine technology, and in particular to an adjustable guide rail device and a method for adjusting the guide rail gap. Background Technology
[0002] Gantry shears are used to process scrap metal and are suitable for shearing various shapes and types of mixed scrap steel, such as metal structural parts, automotive parts, and other recycled scrap steel. Existing gantry shears consist of moving blades and fixed blades. The moving blades are mounted on a moving blade holder to form a moving blade frame. Driven by a power source, the moving blade frame moves up and down in conjunction with the fixed blades to shear the material.
[0003] The moving blade holder moves up and down along the guide rail within the gantry frame. As the moving blade holder slides, wear occurs on the guide rail surface, increasing the gap between the moving blade holder and the guide rail. When the wear reaches a certain level, the gap needs to be adjusted to ensure the shearing effect. In existing gantry shearing machines, a wedge block is generally used to adjust the guide rail position to compensate for the gap between the moving blade holder and the guide rail. For example, the guide rail structure for the moving blade holder of a gantry shear disclosed in Chinese Patent CN202021435977.3, and the upper blade holder gap adjustment device for a gantry shearing machine disclosed in Chinese Patent CN202123014975.4, both use wedge blocks to adjust the guide rail position to adjust the gap between the moving blade holder and the guide rail.
[0004] However, in the existing guide rail clearance adjustment schemes described above, when adjusting the clearance between the moving tool holder and the guide rail using a wedge block, the direction of movement (force) of the wedge block is perpendicular to the vertical direction. Because the vertical length of the wedge block is relatively large, it is difficult to achieve uniform horizontal lateral translation over its entire vertical length. Specifically, due to the large vertical length of the wedge block, multiple adjusting bolts need to be spaced along its vertical length to adjust its position. However, when multiple adjusting bolts at different positions are used to adjust the wedge block's position, it is difficult to achieve uniform horizontal lateral translation over its entire vertical length.
[0005] In addition, existing guide rail clearance adjustment solutions often rely on bolts for fastening, requiring multiple bolts for adjustment, which is cumbersome and inconvenient. Summary of the Invention
[0006] The technical problem to be solved by this application is to provide an adjustable guide rail device and a method for adjusting the guide rail gap, in view of the above-mentioned shortcomings of the prior art.
[0007] An adjustable guide rail device is provided, which is arranged on the gantry frame of a gantry shearing machine; the adjustable guide rail device has a guide surface that extends vertically to guide the vertical movement of the moving blade holder, and the adjustable guide rail device includes:
[0008] The fastener is fixedly mounted on the gantry frame;
[0009] An adjusting component is located between the fixed component and the guide surface, and has an inclined surface that is inclined to the guide surface in the vertical direction; with the help of the inclined surface, the adjusting component can move up and down to change the gap between the guide surface and the moving tool holder.
[0010] A driving element is used to drive the adjusting component to move in the vertical direction to adjust the position of the guide surface.
[0011] Optionally, the driving element is used to drive the adjusting member to move a set stroke, so that the guide surface moves towards the moving tool holder by a corresponding adjustment amount.
[0012] Optionally, the adjustable guide rail device further includes a stroke adjustment component; the stroke adjustment component is used to block the adjusting member at the end position of the set stroke, so that the moving stroke of the adjusting member is equal to the set stroke.
[0013] Optionally, the stroke adjustment component includes:
[0014] A limiting block is fixedly mounted on the adjusting member;
[0015] The stroke adjuster is installed on the gantry or fixed component and is used to stop the adjuster from moving when it reaches the end position of the set stroke by blocking the limit block.
[0016] Optionally, the stroke adjustment component is a screw; the screw can be adjusted up and down by rotation so as to block the limit block at a predetermined height position, so that the movement stroke of the adjustment component is equal to the set stroke.
[0017] Optionally, the guide surface is arranged on the adjusting member, and the guide surface and the inclined surface are respectively located on both sides of the adjusting member;
[0018] The inclined surface of the adjusting component forms an inclined surface engagement with the fixing component on the gantry frame.
[0019] Optionally, the adjustable guide rail device further includes a sensor for detecting the travel of the adjusting member; when adjusting the gap between the guide surface and the moving tool holder, the driving element drives the adjusting member to move a set travel according to the sensor detection signal.
[0020] Optionally, the adjustable guide rail device further includes a gap detector for detecting the size of the gap between the guide surface and the moving tool holder;
[0021] When the gap value a detected by the gap detector exceeds the gap threshold a1, the controller generates the set stroke b of the adjusting component based on the gap value a and the predetermined gap standard value a2, and controls the drive element to drive the adjusting component to move the set stroke b; where the formula for calculating the set stroke b is: b=k(a–a2), where k is the displacement conversion coefficient.
[0022] Optionally, the controller performs statistical analysis on the frequency of gap adjustment within a predetermined time period to obtain the adjustment frequency f; when the adjustment frequency f exceeds the frequency threshold, the gap threshold a1 is gradually increased by an increment Δa within a predetermined range until the adjustment frequency f is reduced to within the frequency threshold.
[0023] On the other hand, this application also provides a guide rail gap adjustment method, which is applied to the above-mentioned adjustable guide rail device; the guide rail gap adjustment method includes the following steps:
[0024] Set the adjustment stroke of the adjustment component;
[0025] The driving element drives the adjusting component to move a set stroke, causing the guide to move towards the moving tool holder by the corresponding adjustment amount.
[0026] The technical solution provided in this application has the following technical effects:
[0027] First, in this application, since both the guide surface and the inclined surface extend vertically, the wedge block is also subjected to force in the vertical direction during adjustment. Usually, the vertical length is relatively long, the rigidity is also better, and it is not easy to deform. Therefore, the translation of the guide surface towards the moving tool holder is more uniform during adjustment, and it is also easier to control the adjustment accuracy of the guide rail gap.
[0028] Secondly, during adjustment, a drive element is used to move the adjusting component, making it more convenient and efficient to adjust the gap between the moving tool holder and the guide rail.

Detailed Implementation
[0037] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.
[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0039] In this embodiment, the adjustable guide rail device can be used to conveniently and efficiently adjust the gap between the moving tool holder and the guide rail. (Reference) Figures 3 to 6 An adjustable guide rail device 102 is arranged on the gantry frame 100 of the gantry shearing machine. The adjustable guide rail device 102 has a guide surface 21, which extends vertically to guide the moving blade holder 200 to move vertically.
[0040] Further, the adjustable guide rail device 102 includes a fixing member 10, an adjusting member 20, and a driving element 30, wherein the fixing member 10 is fixedly mounted on the gantry frame 100. The adjusting member 20 is located between the fixing member 10 and the guide surface 21, and has an inclined surface 22 arranged in a vertical direction inclined to the guide surface 21. With the help of the inclined surface 22, the adjusting member 20 can move vertically to change the gap between the guide surface 21 and the moving tool holder 200. The driving element 30 is used to drive the adjusting member 20 to move vertically to adjust the position of the guide surface 21. Further, the driving element 30 is used to drive the adjusting member 20 to move a set stroke, so that the guide surface 21 moves towards the moving tool holder 200 by a corresponding adjustment amount.
[0041] like Figure 5 and Figure 6As shown, multiple guide rails are arranged around the moving blade holder on the gantry frame to guide the moving blade holder 200 up and down, so that the moving blade holder 200 and the fixed blade holder 300 cooperate to cut materials. Specifically, guide rails 101 and adjustable guide rail devices 102 are arranged around the moving blade holder on the gantry frame.
[0042] Specifically, the fixing member 10 is fixedly mounted on the gantry frame 100 and remains stationary relative to the gantry frame 100. The adjusting member 20 is provided with an inclined surface 22 that is inclined in the vertical direction, and the inclined surface 22 is inclined in the vertical direction to the guide surface 21. Based on the inclined surface 22, the position of the guide surface 21 can be adjusted when the adjusting member 20 moves up and down. Here, the adjusting member 20 acts as a wedge block with an inclined surface 22 to adjust the front and rear position of the guide surface 21. The inclined surface 22 of the adjusting member 20 is inclined in the vertical direction and has a relatively long vertical length. When adjusting up and down, the adjusting member moves as a whole in the vertical direction, which has good rigidity and is not easy to deform. During adjustment, the translation of the guide surface towards the moving tool holder is more uniform, and it is easier to control the adjustment accuracy of the guide rail gap.
[0043] It should be understood that the adjusting component can be a single part or a combination of multiple parts.
[0044] refer to Figure 3 and Figure 4 In one embodiment, the guide surface 21 is arranged on the adjusting member 20, and the guide surface 21 and the inclined surface 22 are located on opposite sides of the adjusting member 20. Further, the inclined surface 22 of the adjusting member 20 forms an inclined engagement with the fixing member 10 on the gantry frame 100. Here, the inclined surface 22 of the adjusting member 20 directly engages with the fixing member 10 at an inclined angle, and the gap adjustment is achieved by the inclined engagement between the adjusting member 20 and the fixing member 10. No other intermediate structures are provided between the adjusting member 20 and the fixing member 10, resulting in fewer components and a simple and reliable structure. In another embodiment, the guide surface 21 is arranged on a separate guide rail, and the adjusting member is located between the fixing member and the guide rail. As the adjusting member is adjusted up and down, the guide rail moves closer to or further away from the fixing member, changing the gap between the guide surface 21 and the moving tool holder 200.
[0045] In addition, such as Figure 3 and Figure 4 As shown in the schematic diagram, the guide surface 21 is located at the front of the adjusting member 20, facing the gantry side; the inclined surface 22 is located at the rear of the adjusting member 20, facing the fixing member 10.
[0046] The drive element 30 is mounted on the gantry 100 and is used to drive the adjusting member 20 to move up and down to change the position of the guide surface 21. Specifically, the drive element 30 can be an electric, pneumatic, or hydraulic element, such as a motor, electric cylinder, or hydraulic cylinder. Under the drive of the drive element 30, the adjusting member 20 can operate automatically and is easy to adjust. It should also be noted that the drive element 30 can directly drive the adjusting member 20, or other intermediate transmission components can be provided between the drive element 30 and the adjusting member 20. In one specific embodiment, in the upward extension direction, the inclined surface 22 is inclined away from the guide surface 21; the closer to the upper end, the further away the inclined surface 22 is from the guide surface 21. The drive element 30 is arranged on the upper end of the adjusting member 20 and is movably connected to the adjusting member 20, specifically, it can be hinged.
[0047] It should be understood that, Figure 3 and Figure 4 In the structure shown, both the guide surface 21 and the inclined surface 22 are arranged on the adjusting member 20. With only the adjusting member 20 and the fixing member 10, the structure is simpler. Furthermore, more components can be added to achieve adjustment. In summary, the technical solution of this application utilizes the inclined surface 22 to allow the adjusting member 20 to move the guide surface 21 closer to or further away from the fixing member 10 by adjusting its vertical position. Moreover, the inclined surface 22 of the adjusting member 20 is inclined vertically and has a relatively long vertical length. During vertical adjustment, the adjusting member moves as a whole in the vertical direction, resulting in good rigidity and resistance to deformation. The translation of the guide surface towards the moving tool holder is more uniform during adjustment, making it easier to control the adjustment accuracy of the guide rail gap.
[0048] In this embodiment, based on the inclined surface 22, when the adjusting member 20 moves up and down, the position of the guide surface 21 can be adjusted, thereby changing the gap between the moving tool holder and the guide surface 21. Furthermore, there is a corresponding relationship between the gap adjustment amount and the travel distance of the adjusting member 20. When it is necessary to reduce the gap between the guide surface 21 and the moving tool holder 200, the required travel distance of the adjusting member 20 can be calculated based on the required gap adjustment amount. Therefore, during adjustment, the driving element 30 can be used to drive the adjusting member 20 to move a set distance, which is calculated from the gap adjustment amount, thereby adjusting the gap between the guide surface 21 and the moving tool holder 200 according to the set adjustment amount. This adjustment method is convenient and efficient for adjusting the gap between the moving tool holder and the guide rail.
[0049] refer to Figure 2 In one embodiment, the adjustable guide rail device further includes a stroke adjustment component 103. The stroke adjustment component 103 is used to block the adjusting member 20 at the end position of the set stroke, so that the moving stroke of the adjusting member 20 is equal to the set stroke.
[0050] In one specific embodiment, the stroke adjustment assembly 103 includes a limit block 40 and a stroke adjustment member 50. The limit block 40 is fixedly mounted on the adjustment member 20, and the stroke adjustment member 50 is mounted on the gantry frame 100 or the fixing member 10. It is used to block the limit block 40 and stop the adjustment member 20 from moving when it reaches the end position of the set stroke. It should be understood that the blocking position of the stroke adjustment member 50 is adjustable and is set according to the end position of the set stroke reached by the adjustment member 20.
[0051] Furthermore, the stroke adjusting component 50 is a screw, which can be adjusted up and down by rotation to block the limiting block 40 at a predetermined height, so that the movement stroke of the adjusting component 20 is equal to the set stroke. In a specific example, the driving element 30 is a hydraulic cylinder. When it is necessary to adjust the gap between the guide surface 21 and the moving tool holder 200, the screw is first moved away from the limiting block 40 by a certain distance and then locked. This distance is calculated by the slope ratio to determine the amount of gap that needs to be adjusted. Then, the hydraulic cylinder pushes the adjusting component 20. When the pressure of the hydraulic system reaches a certain threshold, it is determined that the limiting block 40 has been limited by the screw. At this time, the gap is adjusted to the correct position.
[0052] In another embodiment of this application, the adjustable guide rail device further includes a sensor for detecting the travel distance of the adjusting member 20. When adjusting the gap between the guide surface 21 and the moving tool holder 200, the drive element 30 drives the adjusting member 20 to move a set travel distance according to the sensor detection signal. Here, the sensor can be of various types, capable of indirectly or directly measuring the travel distance of the adjusting member 20, such as an infrared sensor, a laser sensor, an ultrasonic sensor, or a limit switch.
[0053] In this embodiment, the adjustable guide rail device further includes a gap detector for detecting the gap between the guide surface 21 and the moving tool holder 200. When the gap value 'a' detected by the gap detector exceeds the gap threshold 'a1', the controller generates a set stroke 'b' for the adjusting member 20 based on the gap value 'a' and a predetermined gap standard value 'a2', and controls the drive element 30 to drive the adjusting member 20 to move the set stroke 'b'. The set stroke 'b' is calculated as: b = k(a – a2), where k is the displacement conversion coefficient.
[0054] When the gap value 'a' detected by the gap detector exceeds the gap threshold 'a1', it can be determined that the gap between the guide surface 21 and the moving tool holder 200 is too large, affecting the shearing function of the equipment. At this time, the required adjustment stroke is obtained by utilizing the correspondence between the moving stroke of the adjusting member 20 and the gap adjustment amount. During adjustment, the driving element 30 can be used to drive the adjusting member 20 to move a set stroke. The set stroke is calculated from the gap adjustment amount, thereby adjusting the gap between the guide surface 21 and the moving tool holder 200 according to the set adjustment amount. The calculation relationship between the gap value 'a' between the guide surface 21 and the moving tool holder 200 and the set stroke 'b' of the adjusting member 20 is b = k(a – a2), where a – a2 is the difference between the currently detected gap value 'a' and the standard gap value 'a2', that is, the gap adjustment amount required to adjust the gap from the currently detected gap value 'a' to the standard gap value 'a2'. After the driving element 30 drives the adjusting member 20 to move the set stroke 'b' based on the set stroke 'b' calculated by the displacement conversion coefficient k, the gap between the guide surface 21 and the moving tool holder 200 becomes the standard gap value 'a2'. This adjustment method is convenient and efficient for adjusting the gap between the moving tool holder and the guide rail. Here, the gap detector detects the size of the gap between the guide surface 21 and the moving tool holder 200. It can be various types of detection devices or sensors, and under the control of the controller, the drive element 30 adaptively adjusts the gap size without manual intervention.
[0055] Furthermore, the controller statistically analyzes the frequency of gap adjustment within a predetermined time period to obtain the adjustment frequency f. When the adjustment frequency f exceeds a frequency threshold, the gap threshold a1 is gradually increased by an increment Δa within a predetermined range until the adjustment frequency f decreases below the frequency threshold. Here, by controlling the gap threshold a1 through the adjustment frequency f, the adjustment frequency f is controlled in reverse, causing it to decrease below the frequency threshold. A higher adjustment frequency f results in more frequent adjustments; excessively frequent adjustments will accelerate the wear of related friction components and affect the normal operation of the equipment.
[0056] This application also provides a method for adjusting guide rail clearance, which is applied to the aforementioned adjustable guide rail device. (Reference) Figure 3 and Figure 4 The adjustable guide rail device includes a guide surface 21, an adjusting element 20, and a driving element 30. For example... Figure 1 As shown, the guide rail clearance adjustment method includes steps S101 and S102. The guide rail clearance adjustment method provided in this application is convenient and efficient for adjusting the clearance between the moving tool holder and the guide rail.
[0057] Step S101: Set the adjustment stroke of the adjustment component.
[0058] In step S102, the driving element drives the adjusting member 20 to move a set stroke, so that the guide surface 21 moves towards the moving tool holder by the corresponding adjustment amount.
[0059] In step S101, the stroke of the adjusting member is set to obtain the required set stroke. Specifically, during the operation of the gantry shear machine, as the moving blade holder moves up and down reciprocatingly, the wear of the guide surface causes the gap between the moving blade holder and the guide rail to increase. The adjustable guide rail device 102 can reduce the gap between itself and the moving blade holder by adjustment. When it is necessary to reduce the gap between the guide surface 21 and the moving blade holder 200, the required gap adjustment amount is first determined, and the required movement stroke of the adjusting member 20 is calculated based on the required gap adjustment amount. In step S102, during adjustment, the driving element 30 is used to drive the adjusting member 20 to move the set stroke. The set stroke is calculated from the gap adjustment amount, thereby realizing the adjustment of the gap between the guide surface 21 and the moving blade holder 200 according to the set adjustment amount. This adjustment method is convenient and efficient for adjusting the gap between the moving blade holder and the guide rail.
[0060] In one embodiment, the set stroke is determined manually, and the drive element drives the adjuster 20 to move according to the manually determined set stroke. In another embodiment, a gap detector can be used to detect the gap between the guide surface 21 and the moving tool holder 200. When the gap value a detected by the gap detector exceeds the gap threshold a1, the controller generates a set stroke b for the adjuster 20 based on the gap value a and a predetermined gap standard value a2, and controls the drive element 30 to drive the adjuster 20 to move the set stroke b.
