Description

Technical Field

[0001] The invention relates to the technical field of shearing machines, and in particular to a shearing machine and a method for producing a high-low plate bin grid transport semitrailer. Background Art

[0002] The high-low plate-bar type transport semi-trailer is used to connect trucks and carry a large amount of cargo. It is welded and installed by a large number of metal plates or columnar structures. In the production process of the semi-trailer, a shearing machine is often needed to shear the metal to produce a metal plate of a suitable shape; the shearing machine is a forging machine, which is driven by hydraulic pressure. On the workbench, two sets of parallel knives are set, one set of knives is fixed and the other set is moving. The two sets of relatively moving knives are used to shear the metal plate. Due to the need to adjust the distance between the two sets of knives for metal plates of different thicknesses (hereinafter referred to as materials); in the prior art, the main The tools need to be fixed with bolts and coordinated with structures such as hydraulic rods so that a group of moving tools can be flexibly adjusted according to the thickness of the material. However, the use of hydraulic rods to push the tools to adjust the spacing is not accurate enough, and it is easy for the tool spacing to exceed the predetermined range (generally speaking, the tool spacing needs to be between 1 / 10 and 1 / 20 of the material thickness). The hydraulic rod is completely electrically controlled and cannot directly contact the material by physical means. This is because the thickness of the material cannot cross the large error gap of the analog signal, which ultimately leads to deviations in the tool spacing adjustment, affecting the subsequent shearing process.

[0007] Preferably, the axis of the connecting column is higher than the axis of the supporting column, and the axis of the supporting column is located on the lower right side of the axis of the connecting column. The outer surface of the connecting column is movably sleeved with a mounting tube, the telescopic end of the telescopic rod three is fixedly connected to the mounting tube, and the non-retractable end of the telescopic rod three is rotatably mounted on the outer surface of the support column.

[0008] Preferably, fixed cylinders are fixedly mounted on both the front and rear sides of the top of the slide seat, and the connecting rod is adapted to be inserted into the fixed cylinders.

[0009] Preferably, the clamping mechanism includes a telescopic rod 2, the telescopic rod 2 is fixedly mounted on the top of the inner wall of the movable frame, a fixed plate 1 is fixedly mounted on the telescopic end of the telescopic rod 2, a fixed plate 2 is fixedly mounted on the top of the slider, the fixed plate 1 and the fixed plate 2 are abutted against each other, guide cylinders are fixedly mounted on the left and right sides of the top of the fixed plate 1, a guide column and a spring 2 are movably sleeved inside the guide cylinder, the top of the guide column is fixedly connected to the bottom of the movable frame, and the two ends of the spring 2 are elastically connected to the guide column and the fixed plate 1 respectively.

[0010] Preferably, the fixing plate 1 and the fixing plate 2 are both made of asbestos-based friction material or semi-metallic friction material or composite fiber friction material, and the area of ​​the fixing plate 1 is larger than that of the fixing plate 2.

[0011] Preferably, when the telescopic rod 4 drives the positioning plate to move to the lowest point, the positioning plate is lower than the bottom of the movable tool.

[0012] Preferably, the sliding seat moves up and down along the axis of the connecting rod, and the sliding block moves left and right along the axis of the support.

[0013] The working method of the shearing machine for producing high and low silo grid transport semi-trailer includes the following steps: S1. Start the telescopic rod 1 and drive the fixed block to move upward, feed the material from the right side of the device, and move it to the bottom of the fixed block; S2. Start the telescopic rod 1 and drive the fixed block to move downward to press the material and complete the fixation; S3. Start the hydraulic cylinder and drive the movable frame, the slider, the fixed frame and the movable cutter to move downward, so that the movable cutter and the fixed cutter move relative to each other and shear the material, and the sheared material is discharged downward along the discharge chute; S4. When the thickness of the material increases, the material is pressed and fixed according to the above method, the hydraulic cylinder is controlled to move upward, the mobile tool moves to the highest point, the telescopic rod four is started, and the positioning plate is driven downward to a height lower than the mobile tool; S5. Start the telescopic rod 2 and drive the fixed plate 1 to move upward to release the clamping limit of the slider; S6. Start the hydraulic cylinder and drive the mobile frame, the slide block, the fixed frame and the mobile tool to move downward, so that the positioning plate contacts the surface of the material. As the material thickness increases, the height at which the material originally contacts the positioning plate increases, so that the positioning plate, under the limit of the material surface, drives the telescopic rod 4, the slide block and the telescopic rod 3 upward in the reverse direction, so that the fixed frame is forced to move to the left, thereby increasing the distance between the mobile tool and the fixed tool; S7. Then, start the telescopic rod 2 and drive the fixed plate 1 to move down again, press the slider so that the slider cannot slide along the surface of the pillar; S8. Start the telescopic rod 4 and drive the positioning plate to move up and reset; S9. Finally, the movable tool and the fixed tool complete the increase of the adjustment spacing; if the component needs to be reduced, a gap will be left between the positioning plate and the material surface. At this time, the compressed spring 1 will push the slider to the right, and the slider will drive the telescopic rod 3 to move right through the fixed frame. Under the limiting action of the connecting rod, the slide seat moves downward as a whole, and at the same time, the distance between the movable tool and the fixed tool is automatically reduced.

[0014] The working principle and beneficial effects of the present invention are: When the movable frame is driven by the hydraulic cylinder to move downward, the telescopic rod four is extended downward and drives the positioning plate to move to the lowest point, so that the positioning plate abuts against the material placed on the surface of the workbench. The material has a plate thickness and pushes the positioning plate upward to the height of the plate thickness. At this time, the freely sliding slider is movably connected with the slide seat through the fixed frame and the telescopic rod three. Since the telescopic rod three is of a fixed length at this time, the positioning plate pushes the slide seat upward and moves vertically under the limiting action of the connecting rod. At this time, the telescopic rod three rotates counterclockwise and pushes the fixed frame and the slider to move left. At this time, the mobile tool is driven left by the fixed frame, so that the tool distance between the mobile tool and the fixed tool can be increased, thereby completing the automatic adjustment function of the tool distance. This design directly abuts against the material through physical means, which greatly improves the accuracy of tool distance adjustment.

[0015] 2. The device is also provided with a telescopic rod three that can be freely extended and retracted. The movement direction of the slider, the fixed frame and the movable tool is limited to the horizontal direction by a support, and the height of the fixed frame cannot be changed. The horizontal position of the slide seat and the support column is limited by a connecting rod, so that they can only move in the vertical direction and cannot change the horizontal position. According to the design requirements of the tool distance, the tool distance needs to be controlled between 1 / 10 and 1 / 20 of the material plate thickness. The fixed length of the telescopic rod three is changed by changing the extension degree of the telescopic rod three, so that the positioning plate can move the material plate thickness while driving the slider to move horizontally along the outer surface of the support through the telescopic rod three. The travel of 1 / 10 to 1 / 20 of the material plate thickness.

[0016] 3. The device is also designed with a clamping mechanism located on the inner wall of the mobile frame, so that the movement of the slider on the outer surface of the pillar is effectively restricted. By providing fixed plate 2 and fixed plate 1, the fixed plate 1 is driven by the telescopic rod 2 to press the fixed plate 2 downward and generate a huge friction force, thereby fixing the slider. When shearing operation is performed, the hydraulic cylinder drives the mobile frame and the mobile tool to move and is subjected to a vertical upward reaction force. This force has almost no offsetting effect on the friction force generated between the fixed plate 2 and the fixed plate 1, thereby effectively ensuring the stability of the mobile tool after it is fixed. When the mobile tool and the slider need to move and adjust the tool distance, the telescopic rod 2 drives the fixed plate 1 to break away from the abutment with the fixed plate 2, thereby realizing the free adjustment function of the slider.

DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 8 As shown, the embodiment of the present invention provides a shearing machine for producing a high-low plate silo type transport semi-trailer, including a workbench 1, a top seat 6 and a hydraulic cylinder 7. A material discharge trough 2 is opened on the top of the workbench 1, and a fixed tool 3 is installed on the inner wall of the material discharge trough 2. A fixing mechanism is provided on the top of the workbench 1. A mobile frame 8 is fixedly installed on the telescopic end of the hydraulic cylinder 7. A plurality of groups of pillars 11 are fixedly installed on the inner wall of the mobile frame 8. The right side of the bottom of the mobile frame 8 is fixedly connected with two front and rear groups of connecting rods 22. A slider 12 is slidably installed on the outer surface of the pillar 11, and a spring 13 located on the left side of the slider 12 is movably sleeved. The two ends of the spring 13 are elastically connected to the mobile frame 8 and the slider 12 respectively. Then, a clamping mechanism is provided at the top of the inner wall of the mobile frame 8, so that the movement of the slider 12 on the surface of the pillar 11 is restricted, a fixed frame 18 is fixedly installed at the bottom of the slider 12, a mobile tool 19 is fixedly installed at the bottom of the fixed frame 18, a connecting column 20 is fixedly installed on the right side of the fixed frame 18, a slide seat 23 is movably sleeved on the outer surface of the connecting rod 22, a support column 24 is fixedly installed on the top of the slide seat 23, a telescopic rod three 25 is movably connected between the connecting column 20 and the support column 24, a telescopic rod four 26 is fixedly installed in the middle of the slide seat 23, and a positioning plate 27 is fixedly connected to the telescopic end of the telescopic rod four 26, and the bottom of the positioning plate 27 is higher than the bottom of the mobile tool 19; The shearing machine has been redesigned so that it can automatically adjust the distance between the mobile tool 19 and the fixed tool 3 (hereinafter referred to as the tool distance) according to the thickness of the material. Figure 2As shown: first determine the tool distance zero point, that is, start the hydraulic cylinder 7 and drive the moving frame 8, the moving tool 19 and the slide 23 to move up to the highest point, start the telescopic rod 26 to extend downward to the maximum stroke, at this time the relative position between the positioning plate 27 and the bottom of the slide 23 is the largest, start the hydraulic cylinder 7 and drive the moving frame 8, the moving tool 19, the slide 23 and the positioning plate 27 to move downward until the bottom of the positioning plate 27 abuts against the surface of the workbench 1, at this time, the gap between the moving tool 19 and the fixed tool 3 is the smallest, and the slider 12 moves to the far right under the action of the spring 13 and is held by the outer surface of the support 11 The limit ring on it abuts against the limit, and when the thickness of the material plate located on the surface of the workbench 1 increases, the positioning plate 27 will drive the telescopic rod four 26, the slide seat 23, the support column 24 and the telescopic rod three 25 to move upward. At this time, the non-telescopic end of the telescopic rod three 25 will rotate counterclockwise around the axis of the support column 24, and since the telescopic rod three 25 is movably connected with the fixed frame 18 and the slide block 12 through the connecting column 20 and the mounting cylinder 21, the telescopic rod three 25 will synchronously push the fixed frame 18 and the slide block 12 to the left, that is, push the movable tool 19 to move to the left, thereby synchronously increasing the gap between the movable tool 19 and the fixed tool 3.

[0022] The device is provided with a movable frame 8 and a support 11 to slide and install a slide block 12, so that the slide block 12 drives the fixed frame 18 and the movable tool 19 to move freely in the horizontal direction, and the fixed frame 18 and the slide seat 23 are synchronously connected by the telescopic rod 3 25. When the hydraulic cylinder 7 drives the movable frame 8 to move downward, the telescopic rod 4 26 is extended downward and drives the positioning plate 27 to move to the lowest point, so that the positioning plate 27 is in contact with the material placed on the surface of the workbench 1. The material has a plate thickness, and the positioning plate 27 is pushed upward to the height of the plate thickness. At this time, the freely sliding slide The block 12 is movably connected with the slide 23 through the fixed frame 18 and the telescopic rod three 25. Since the telescopic rod three 25 is of fixed length at this time, the positioning plate 27 pushes the slide 23 upward and moves vertically under the limiting action of the connecting rod 22. At this time, the telescopic rod three 25 rotates counterclockwise and pushes the fixed frame 18 and the slide block 12 to move to the left. At this time, the mobile tool 19 is driven to the left by the fixed frame 18, which can increase the knife distance between it and the fixed tool 3, completing the automatic adjustment function of the knife distance. This design directly contacts the material through physical means, which greatly improves the accuracy of the knife distance adjustment.

[0023] The device is also provided with a telescopic rod 3 25 that can be freely extended and retracted. The movement direction of the slider 12, the fixed frame 18 and the movable tool 19 is limited to the horizontal direction by the support 11, and the height of the fixed frame 18 cannot be changed. The horizontal position of the slide 23 and the support column 24 is limited by the connecting rod 22, so that they can only move in the vertical direction and cannot change the horizontal position. According to the design requirements of the tool distance, the tool distance needs to be controlled between 1 / 10 and 1 / 20 of the material plate thickness. By changing the extension degree of the telescopic rod 3 25 and the fixed length of the telescopic rod 3 25, the positioning plate 27 can move the height of the material plate while driving the slider 12 to move horizontally along the outer surface of the support 11 through the telescopic rod 3 25. The travel of 1 / 10 to 1 / 20 of the material plate thickness.

[0024] Among them, the top seat 6 is fixedly installed on the top of the workbench 1, the hydraulic cylinder 7 is fixedly installed on the top of the top seat 6, the movable tool 19 and the fixed tool 3 are staggered left and right, and a gap is left, and the fixing mechanism is located on the right side of the fixed tool 3; The movable cutter 19 and the fixed cutter 3 are interlaced with each other and leave a gap, so that the material can be sheared. The fixing mechanism is composed of a telescopic rod 4 and a fixed block 5 to complete the pressing and fixing of the material.

[0025] The fixing mechanism includes a telescopic rod 4 and a fixing block 5. The telescopic rod 4 is provided in two groups and is respectively fixedly installed on the front and rear sides of the inner wall of the workbench 1. The fixing block 5 is fixedly installed on the telescopic end of the telescopic rod 4 and abuts against the top of the workbench 1. The fixing mechanism is arranged on the surface of the workbench 1, and is completely separated from the hydraulic cylinder 7 and the movable tool 19, so as to facilitate the control operation.

[0026] The axis of the connecting column 20 is higher than the axis of the supporting column 24, and the axis of the supporting column 24 is located at the lower right side of the axis of the connecting column 20. The outer surface of the connecting column 20 is movably sleeved with a mounting tube 21, and the telescopic end of the telescopic rod 3 25 is fixedly connected to the mounting tube 21, and the non-retractable end of the telescopic rod 3 25 is rotatably mounted on the outer surface of the supporting column 24. The positions of the fixed frame 18 and the slide 23 are set so that when the slide 23 moves upward, the slide block 12 is pushed to the left through the telescopic rod 3 25 movably connected between the two. This design increases the thickness of the material plate while the distance between the movable tool 19 and the fixed tool 3 can also be increased synchronously.

[0027] Among them, the front and rear sides of the top of the slide seat 23 are fixedly installed with a fixing cylinder 28, and the connecting rod 22 is adapted to be inserted into the fixing cylinder 28; When the slide 23 is moving downward, in order to prevent the slide 23 from being separated from the outer surface of the connecting rod 22 , a fixing cylinder 28 is installed to increase the maximum stroke of the downward movement of the slide 23 .

[0028] Among them, the clamping mechanism includes a telescopic rod 29, which is fixedly installed on the top of the inner wall of the mobile frame 8, and a fixed plate 10 is fixedly installed on the telescopic end of the telescopic rod 29, and a fixed plate 2 14 is fixedly installed on the top of the slider 12, and the fixed plate 10 and the fixed plate 2 14 are abutted, and guide cylinders 16 are fixedly installed on the left and right sides of the top of the fixed plate 10, and the guide cylinder 16 is movably sleeved with a guide column 15 and a spring 2 17 inside, and the top of the guide column 15 is fixedly connected to the bottom of the mobile frame 8, and the two ends of the spring 2 17 are elastically connected to the guide column 15 and the fixed plate 10 respectively; The device is also designed with a clamping mechanism located on the inner wall of the mobile frame 8, so that the movement of the slider 12 on the outer surface of the pillar 11 is effectively restricted. By providing a fixed plate 2 14 and a fixed plate 10, the fixed plate 10 is driven by the telescopic rod 2 9 to press the fixed plate 2 14 downward and generate a huge friction force, thereby fixing the slider 12. When the shearing operation is performed, the hydraulic cylinder 7 drives the mobile frame 8 and the mobile tool 19 to move and is subjected to a vertical upward reaction force. This force has almost no offsetting effect on the friction force generated between the fixed plate 2 14 and the fixed plate 10, thereby effectively ensuring the stability of the mobile tool 19 after being fixed. When the mobile tool 19 and the slider 12 need to move and adjust the knife distance, the telescopic rod 2 9 drives the fixed plate 10 to disengage from the abutment with the fixed plate 2 14, thereby realizing the free adjustment function of the slider 12.

[0029] Wherein, the fixing plate 1 10 and the fixing plate 2 14 are both made of asbestos-based friction material or semi-metal friction material or composite fiber friction material, and the area of ​​the fixing plate 1 10 is larger than the area of ​​the fixing plate 2 14; The fixing plate 1 10 and the fixing plate 2 14 are made of the same material as the automobile clutch, and the friction force generated by the abutment is huge. They are not only easy to obtain and low in cost, but also have extremely high reliability.

[0030] When the telescopic rod 26 drives the positioning plate 27 to move to the lowest point, the positioning plate 27 is lower than the bottom of the moving tool 19; The positioning plate 27 moves downward to the lowest point relative to the slide 23, thereby assisting the slide 12 and the moving tool 19 to determine the tool distance zero point.

[0031] The slide 23 moves up and down along the axis of the connecting rod 22, and the slider 12 moves left and right along the axis of the support 11; The synchronous movement of the slide 23 and the slider 12 realizes the automatic adjustment of the knife distance, and the movement tracks of the connecting rod 22 and the slider 12 are strictly limited, so that their respective strokes are transformed into each other.

[0032] The working method of the shearing machine for producing high and low silo grid transport semi-trailer includes the following steps: S1. Start the telescopic rod 4 and drive the fixed block 5 to move upward, feed the material from the right side of the device, and move it to the bottom of the fixed block 5; S2. Start the telescopic rod 4 and drive the fixed block 5 to move downward to press the material and complete the fixation; S3. Start the hydraulic cylinder 7, and drive the movable frame 8, the slider 12, the fixed frame 18 and the movable tool 19 to move downward, so that the movable tool 19 moves relative to the fixed tool 3, and the material is sheared, and the sheared material is discharged downward along the lower chute 2; S4. When the thickness of the material increases, the material is pressed and fixed according to the aforementioned method, the hydraulic cylinder 7 is controlled to move upward, the mobile tool 19 moves to the highest point, the telescopic rod 26 is started, and the positioning plate 27 is driven downward to a height lower than the mobile tool 19; S5. Start the telescopic rod 2 9 and drive the fixed plate 10 to move upward to release the clamping limit of the slider 12; S6. Start the hydraulic cylinder 7 and drive the movable frame 8, the slider 12, the fixed frame 18 and the movable tool 19 to move downward, so that the positioning plate 27 abuts against the surface of the material. As the thickness of the material increases, the height at which the material originally abuts against the positioning plate 27 increases, so that the positioning plate 27 is limited on the surface of the material, and drives the telescopic rod 4 26, the slide 23, and the telescopic rod 3 25 upward in the reverse direction, so that the fixed frame 18 is forced to move to the left, thereby increasing the distance between the movable tool 19 and the fixed tool 3; S7. Then, start the telescopic rod 9 and drive the fixed plate 10 to move down again, and tighten the slider 12 so that the slider 12 cannot slide along the surface of the support 11; S8. Start the telescopic rod 26 and drive the positioning plate 27 to move up and reset; S9. Finally, the movable tool 19 and the fixed tool 3 complete the increase of the adjustment spacing; if the component needs to be reduced, a gap will be left between the positioning plate 27 and the surface of the material. At this time, the compressed spring 13 will push the slider 12 to the right, and the slider 12 will drive the telescopic rod 3 25 to move right through the fixed frame 18. Under the limiting action of the connecting rod 22, the slide seat 23 moves downward as a whole, and at the same time, the spacing between the movable tool 19 and the fixed tool 3 is automatically reduced.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

10. The working method of the shearing machine for producing high-low plate silo type transport semi-trailer according to claim 9, characterized in that: The following steps are involved: S1. Start the telescopic rod (4) and drive the fixed block (5) to move upward, feed the material from the right side of the device, and move it to the bottom of the fixed block (5); S2. Start the telescopic rod (4) and drive the fixed block (5) to move downward to press the material and complete the fixation; S3. Start the hydraulic cylinder (7), and drive the movable frame (8), the slider (12), the fixed frame (18) and the movable tool (19) to move downward, so that the movable tool (19) and the fixed tool (3) move relative to each other, and the material is sheared off, and the sheared material is discharged downward along the discharge chute (2); S4. When the thickness of the material increases, the material is pressed and fixed according to the above method, the hydraulic cylinder (7) is controlled to move upward, so that the movable tool (19) moves to the highest point, the telescopic rod (26) is started, and the positioning plate (27) is driven downward to a height lower than the movable tool (19); S5. Start the telescopic rod 2 (9), and drive the fixed plate 1 (10) to move upward, releasing the clamping limit of the slider (12); S6. The hydraulic cylinder (7) is started, and the movable frame (8), the slide block (12), the fixed frame (18) and the movable cutter (19) are driven downward, so that the positioning plate (27) contacts the surface of the material. As the thickness of the material increases, the height at which the material originally contacts the positioning plate (27) increases, so that the positioning plate (27) is limited by the surface of the material, and drives the telescopic rod (26), the slide block (23) and the telescopic rod (25) upward in the reverse direction, so that the fixed frame (18) is forced to move to the left, thereby increasing the distance between the movable cutter (19) and the fixed cutter (3); S7. Then, the telescopic rod 2 (9) is started, and the fixed plate 1 (10) is moved down again, and the slider (12) is pressed so that the slider (12) cannot slide along the surface of the support (11); S8. Start the telescopic rod four (26), and drive the positioning plate (27) to move up and reset; S9. Finally, the movable cutter (19) and the fixed cutter (3) complete the increase of the adjustment spacing; if the assembly needs to be reduced, a gap will be left between the positioning plate (27) and the surface of the material. At this time, the compressed spring 1 (13) will push the slider (12) to the right, and the slider (12) will drive the telescopic rod 3 (25) to move to the right through the fixed frame (18). Under the limiting action of the connecting rod (22), the slide seat (23) moves downward as a whole, and at the same time, the spacing between the movable cutter (19) and the fixed cutter (3) is automatically reduced.
