Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to a tracked high-speed gantry shearing machine. Background Technology

[0002] The tracked high-speed gantry shear is a heavy-duty equipment designed for the "mobile and efficient processing" of metal scrap. The tracked design allows the device to move flexibly and quickly to the scrap site to cut scrap steel, steel plates and other materials in batches. It is a core device in the scrap recycling and metallurgical industries.

[0003] Existing gantry shears typically place the waste material on the lower blades when shearing it, and then the upper cylinder drives the shear blades downwards to fit and compress the waste material. However, when the cylinder drives the blades downwards for cutting or upwards after cutting, the large volume of the cylinder results in a slow filling speed and a long time for the drive oil. Therefore, the up-and-down movement speed of the blades driven by the cylinder is relatively slow. If a large amount of waste material needs to be sheared, the slow up-and-down movement speed of the blades will result in low efficiency. Utility Model Content

[0004] This utility model proposes a tracked high-speed gantry shearing machine, which solves the problem in the prior art where the cutting tool moves up and down slowly due to the slow oil filling speed, thus affecting the subsequent cutting efficiency.

[0005] The technical solution of this utility model is as follows:

[0006] A tracked high-speed gantry shearing machine includes a shearing machine body, a processing box, a speed-up cylinder, a hydraulic cylinder, a filling valve, and a shearing blade. The processing box is fixedly installed on the shearing machine body, and an oil storage tank is fixedly installed on the side of the processing box. The speed-up cylinder is installed inside the processing box. There are two hydraulic cylinders, both of which are installed on the processing box. There are two filling valves, both of which are installed on the processing box. The shearing blade is installed on the output ends of the two hydraulic cylinders. The shearing blade is slidably installed on the inner side wall of the processing box via a slider, and the output end of the speed-up cylinder is connected to the top end of the shearing blade. Support assemblies are provided on both sides of the processing box to support the shearing blade when not shearing.

[0007] Furthermore, the support assembly includes a hydraulic cylinder, a support rod, and a connecting frame. The hydraulic cylinder is mounted on the side of the processing box, the support rod is slidably mounted through the side of the processing box, and the connecting frame is fixedly mounted between the support rod and the output end of the hydraulic cylinder.

[0008] Furthermore, a through hole is provided on the side of the slider, and the support rod is slidably installed through the through hole on the side of the slider.

[0009] Furthermore, the two inner sidewalls of the processing box are provided with trapezoidal grooves, and the two sliders are respectively slidably installed in the two trapezoidal grooves.

[0010] Furthermore, the bottom of the processing box is provided with a placement groove for placing the lower cutting tool, and a cover plate is bolted to the top of the placement groove.

[0011] Furthermore, the two cylinders are respectively connected to the two filling valves, and both filling valves are connected to the oil storage tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, when shearing waste board, the output ends of the two hydraulic cylinders drive the shearing blade to slide downwards within the processing box via a slider. At this time, the filling valve opens, filling the hydraulic cylinder with oil from the storage tank, thus powering it. When the shearing blade contacts the material, the filling valve closes, and the hydraulic cylinder drives the shearing blade to shear the waste board. After shearing, when it is necessary to rise, the filling valve is opened again, filling the storage tank with oil from the hydraulic cylinder. At this time, the speed-up cylinder drives the shearing blade and the output ends of the two hydraulic cylinders to move upwards rapidly, thereby achieving the effect of increasing speed.

[0014] Furthermore, when shearing is not required, the two sliders can be supported by the support components, which in turn supports the shearing blade, thereby reducing the "pressure" on the output end of the speed-up cylinder. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-6 As shown, this embodiment proposes a tracked high-speed gantry shearing machine, including a shearing machine body 1, a processing box 2, a speed-up cylinder 4, a hydraulic cylinder 5, a filling valve 12, and a shearing blade 10. The processing box 2 is fixedly installed on the shearing machine body 1, and an oil storage tank 3 is fixedly installed on the side of the processing box 2. The speed-up cylinder 4 is installed inside the processing box 2. There are two hydraulic cylinders 5, both of which are installed on the processing box 2. There are two filling valves 12, both of which are installed on the processing box 2. The shearing blade 10 is installed on the output ends of the two hydraulic cylinders 5. The shearing blade 10 is slidably installed on the inner side wall of the processing box 2 via a slider 11, and the output end of the speed-up cylinder 4 is connected to the top end of the shearing blade 10. Support components are provided on both sides of the processing box 2 to support the shearing blade 10 when not shearing.

[0025] like Figure 6 As shown, when shearing a workpiece, the shearing machine body 1 can move the device to a designated location via its track. Then, the waste material is placed inside the shearing machine body 1. It should be noted that the material feeding area of ​​the shearing machine body 1 is equipped with a box cover, which can be opened and closed by a hydraulic cylinder. When feeding, the material is placed inside the shearing machine body 1, and then the box cover is closed by the hydraulic cylinder. Subsequently, the waste material is pushed into the lower cutter by the pusher plate inside the shearing machine body 1 for subsequent shearing.

[0026] It should be added that a pushing cylinder is installed inside the shearing machine body 1. The pushing cylinder has a pushing stroke of 7 meters and is divided into three sections, which can push the material added into the shearing machine body 1 forward. A counting scale is placed side by side on the side of the pushing cylinder and the pushing plate. The counting scale is divided into segments of 10 centimeters, and a corresponding sensor is installed on the counting scale. Therefore, the pushing size can be controlled by the counting scale, and the material can be pushed forward to cut the corresponding length.

[0027] like Figure 2 and Figure 4 As shown, after the material is pushed, the speed-up cylinder 4 and the two oil cylinders 5 are started. Since the two oil cylinders 5 are connected to the two filling valves 12 respectively, and the two filling valves 12 are connected to the oil storage tank 3, the filling valves 12 are opened at this time. The output end of the oil cylinder 5 and the output end of the speed-up cylinder 4 drive the shearing blade 10 to move down. Since the two inner side walls of the processing box 2 are provided with trapezoidal grooves, and the two sliders 11 are slidably installed in the two trapezoidal grooves respectively, the two ends of the shearing blade 10 can slide smoothly inside the processing box 2 through the sliders 11. At this time, the filling valve 12 is opened, and the oil in the oil storage tank 3 is added into the oil cylinder 5. When the shearing blade 10 contacts the material, the filling valve 12 is closed. At this time, the oil cylinder 5 drives the shearing blade 10 to shear the waste material. After the shearing is completed, the filling valve 12 is opened again to backfill the oil in the oil cylinder 5 into the oil storage tank 3. Then, the speed-up cylinder 4 drives the output end of the oil cylinder 5 and the shearing blade 10 to move up, thereby achieving the effect of speed increase.

[0028] It should be added that a pressing cylinder is installed behind the two cylinders 5. The output end of the pressing cylinder is located inside the shearing machine body 1. When the material is pushed over, the output end of the pressing cylinder drives the pressing plate to move down to press the material, which facilitates subsequent shearing.

[0029] like Figure 3 As shown, when shearing is not required, the shearing blade 10 can be supported by a support assembly, which includes a hydraulic cylinder 6, a support rod 7, and a connecting frame 8. The hydraulic cylinder 6 is mounted on the side of the processing box 2, and the support rod 7 is slidably mounted through the side of the processing box 2. The connecting frame 8 is fixedly mounted between the support rod 7 and the output end of the hydraulic cylinder 6. Specifically, because the slider 11 has a through hole on its side, and the support rod 7 is slidably mounted through the through hole on the side of the slider 11, the output end of the hydraulic cylinder 6 can be driven to move the connecting frame 8 forward by activating the hydraulic cylinder 6. The connecting frame 8 then drives the support rod 7 through the side of the processing box 2 and into the through hole of the slider 11, thereby supporting the slider 11 and further supporting the bottom of the shearing blade 10. Thus, part of the downward pressure of the shearing blade 10 can be distributed to the processing box 2. It should be noted that the shearing machine body 1 can supply power to the hydraulic cylinder 6 through its own power supply.

[0030] It should be added that a large oil tank is installed at the rear end of the shearing machine body 1, and two oil pipes and six oil pipes are distributed on both sides of the shearing machine body 1 respectively. The two oil pipes on one side supply oil to the pressing cylinder through the oil pump. Of the six oil pipes on the other side, two oil pipes are connected to the speed-up cylinder 4 to supply oil to it, the other two oil pipes supply oil to the two cylinders 5 respectively, and the last two are connected to the hydraulic cylinder of the control box cover to supply oil to it.

[0031] like Figure 5 As shown, the bottom of the machining box 2 is provided with a groove for placing the lower tool, and a cover plate 9 is bolted to the top of the groove. Therefore, the cover plate 9 can be removed by unscrewing the bolts, so that the lower tool can be replaced and repaired.

[0032] The oil storage tank 3 of the shearing machine body 1 and the large oil tank at the rear end of the shearing machine body 1 are connected by an oil pipe. When the oil in the oil storage tank 3 is full, it can be sensed by the sensor, and then the oil in the oil storage tank 3 can be filled into the large oil tank through the oil pump and oil pipe.

[0033] Working principle: When shearing materials, the shearing machine body 1 is moved to a designated location by its track. Waste material is then placed inside the shearing machine body 1 and pushed to the shearing position in the processing box 2. After pushing, the speed-up cylinder 4 and two hydraulic cylinders 5 are activated. At this time, the filling valve 12 is opened, and the output ends of hydraulic cylinders 5 and speed-up cylinder 4 drive the shearing blade 10 downwards. Both ends of the shearing blade 10 can slide smoothly inside the processing box 2 via sliders 11. Because the filling valve 12 is open, oil from the oil storage tank 3 is added to the hydraulic cylinder 5. When the shearing blade 10 contacts the material, the filling valve 12 closes. The hydraulic cylinder 5 then drives the shearing blade 10 to shear the waste material. After shearing, the filling valve 12 reopens, backfilling the oil from the hydraulic cylinder 5 into the oil storage tank 3. Then, the speed-up cylinder 4 drives the output end of the hydraulic cylinder 5 and the shearing blade 10 upwards, thereby achieving a speed-up effect.

[0034] It should also be noted that all oil pipelines are made of high-pressure wear-resistant tubing, and the pipe joints adopt a compression fitting sealing structure to prevent oil leakage. One-way valves and flow sensors are installed on the oil pipelines between the oil storage tank 3 and the large oil tank. When the oil level in the oil storage tank 3 is higher than the preset value, the flow sensor sends a signal to start the oil pump to transport the excess oil back to the large oil tank. Furthermore, the shearing machine body 1 is equipped with a PLC control system, which can control the driving and stopping of the filling valve 12, the oil cylinder 5, and the speed-up cylinder 4.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
