Description

Technical Field

[0001] The utility model relates to the technical field of shearing, in particular to a shearing device for insulating composite materials. Background Art

[0002] Shearing machine is a kind of machine tool. It adopts hydraulic drive, reliable safety performance, easy operation, and eight levels of shearing force from 63 tons to 400 tons, which can meet the needs of users of different sizes and requirements. It does not require foot screws for installation, and can be powered by diesel engines in places without power supply. Shearing machine is suitable for metal recycling processing plants, scrap car dismantling sites, smelting and casting industries. It can perform cold shearing, pressing and flanging of various shapes of steel and various metal materials, as well as pressing and forming powder products, plastics, fiberglass, insulation materials, and rubber.

[0003] In the prior art, there is a shearing device for insulating composite materials, such as the Chinese patent number CN210702794U, which includes a shearing table, a cutter seat, and a jack. The shearing table is provided with a first lower cutter, which is a flat-edge cutter. The cutter seat is vertically provided with a first upper cutter and a second upper cutter, which is a flat-edge cutter and the second upper cutter is a saw-edge cutter. An upper slider is slidably connected to the lower end of the cutter seat, and the upper slider can slide longitudinally. The first upper cutter and the second upper cutter are inserted in the upper slider. When the upper slider slides to an extreme position, the first upper cutter slides out, and when the upper slider slides to another extreme position, the second upper cutter slides out.

[0004] However, in the prior art, although the above patent has the above technical advantages, the disadvantage is that when the cutter is cutting the insulating composite material, the insulating composite material is not fixed, and the cutter is prone to displacement when cutting the material. If the cutting is performed after the displacement, it will affect the size of the standard insulating composite material. When cutting, the cutter is prone to produce debris and dust when cutting the material, which will accumulate for a long time and easily affect the cutting work. For example, the working surface is uneven due to dust accumulation, and the working surface needs to be manually cleaned after the work is completed, which is time-consuming and labor-intensive. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model adopts the following technical solution to solve the technical problems: a shearing device for insulating composite materials, comprising a frame, a base is fixedly connected to the lower surface of the frame, a hydraulic cylinder is fixedly connected to the inner surface of the frame, a hydraulic rod is slidably connected to the inner surface of the hydraulic cylinder, a cutter is fixedly connected to the lower surface of the hydraulic rod, a fixed rod is fixedly connected to the outer surface of the hydraulic rod, a nozzle is fixedly connected to the upper surface of the base, an air pipe is fixedly connected to the outer surface of the nozzle, a spring is fixedly connected to the inner surface of the frame, a compression rod is fixedly connected to the bottom end of the spring, and the up and down movement of the hydraulic cylinder is used to drive the operation of the equipment.

[0006] Preferably, the lower surface of the compression rod is in contact with the outer surface of the fixed rod, the outer surface of the compression rod is slidably connected to the inner surface of the frame, the inner surface of the frame is fixedly connected with an outer tube, the front end of the outer tube is fixedly connected to the top end of the air pipe, and the air moves from the frame to the outer tube through the connection between the air pipe and the outer tube.

[0007] Preferably, the inner surface of the outer tube is fixedly connected to the inner tube, the inner surface of the inner tube is slidably connected to an air plug, the outer surface of the air plug is fixedly connected to a resistance rod, the outer surface of the resistance rod is fixedly connected to the inner surface of the inner tube, the resistance rod blocks the flow of air, when the pressure in the tube is greater than the resistance of the resistance rod, the piston on the resistance rod moves to the rear of the hole on the surface of the inner tube, allowing the compressed air in the tube to enter the trachea.

[0008] Preferably, the outer surface of the frame is fixedly connected to a shell, the inner surface of the shell is slidably connected to a pressure block, the upper surface of the pressure block contacts the outer surface of the fixed rod, the lower surface of the pressure block is fixedly connected to a compression spring, the bottom end of the compression spring is fixedly connected to the inner surface of the shell, and the pressure block compresses the air in the shell.

[0009] Preferably, a connecting tube is fixedly connected to the lower surface of the shell, a top sheet is fixedly connected to the bottom end of the connecting tube, and a compression shell is fixedly connected to the outer surface of the top sheet. The top sheet not only fixes the tension spring but also does not hinder airflow.

[0010] Preferably, the outer surface of the top plate is fixedly connected with a tension spring, the bottom end of the tension spring is fixedly connected with a slider, the outer surface of the slider is slidably connected to the inner surface of the compression shell, the inner surface of the compression shell is rotatably connected with a lead screw, the outer surface of the lead screw is rotatably connected to the inner surface of the frame, and the tension spring resets the slider after movement.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model provides a pressure block. When the hydraulic rod performs shearing work on the insulating composite material, it drives the fixed rod to compress the pressure block, compresses the air in the shell, moves the air to the connecting pipe, and then moves to the inside of the compression shell through the connecting pipe. Under the pressure of the air, the slider is forced to move downward to fix the insulating composite material. A screw rod is provided inside the compression shell. By rotating the turntable above the screw rod, the height of the compression shell can be adjusted to adapt to insulating composite materials of different thicknesses. When the compressive force of the fixed rod on the pressure block disappears, the compression spring resets the pressure block, and the tension spring resets the slider, thereby releasing the fixation of the insulating composite material, thereby solving the problem of fixing the position of the insulating composite material during shearing work.

[0013] 2. The utility model provides an air plug. After the cutter completes shearing of the insulating composite material, it moves upward and drives the fixed rod to compress the compression rod, thereby compressing the air inside the frame. When the air pressure is greater than the resistance of the resistance rod, the air pressure pushes the air plug to move to the recess in the inner tube. The air pressure instantly moves from the inner tube to the outer tube, and moves to the blowing nozzle through the air pipe to blow away the dust on the surface of the base. When the cutter resumes shearing, the pressure of the fixed rod on the compression rod disappears, and the spring resets the compression rod. When the air pressure is less than the resistance of the resistance rod, the air plug resets. At the same time, a one-way valve is provided inside the frame to supplement the air blown out from the inside of the frame, thereby solving the problem of blowing dust on the working surface after shearing and reducing the problem of manual cleaning of the working surface.

[0024] Working principle:

[0025] When in use, the insulating composite material is placed on the surface of the base 2. At this time, the hydraulic cylinder 3 is turned on and operated. The hydraulic cylinder 3 drives the hydraulic rod 4 to move downward. A cutter 5 is fixed on the lower surface of the hydraulic rod 4. When the hydraulic rod 4 moves downward, a fixing rod 6 is provided on the outer surface of the hydraulic rod 4. When the fixing rod 6 moves to the upper surface of the pressing block 16, under the continuous pressure of the fixing rod 6 on the pressing block 16, the air in the outer shell 17 is pressed into the compression shell 11 through the connecting pipe 19. A slider 23 is provided inside the compression shell 11. When the air inside the compression shell 11 increases, the slider 23 is forced to move downward, so that the slider 23 presses the insulating composite material tightly against the surface of the base 2.

[0026] When the cutter 5 completes the shearing work on the insulating composite material, the cutter 5 moves upward. At this time, the pressure of the fixed rod 6 on the pressing block 16 disappears, and the compression spring 18 below the pressing block 16 forces the pressing block 16 to reset under the action of elastic force. In addition, the tension spring 22 above the slider 23 resets the slider 23 when the air is reduced. The top plate 21 above the tension spring 22 not only fixes the tension spring 22, but also has many holes on the surface of the top plate 21 to facilitate the air circulation between the connecting pipe 19 and the compression shell 11. A screw rod 20 is rotatably connected to the outer surface of the compression shell 11. By rotating the screw rod 20, the height of the compression shell 11 can be adjusted to adapt to insulating composite materials of different thicknesses.

[0027] When the hydraulic cylinder 3 retracts the hydraulic rod 4, it drives the fixed rod 6 to move upward. When it moves to the lower surface of the compression rod 10, the compression rod 10 is forced to move upward to compress the air inside the frame 1. When the air inside the frame 1 is compressed to a pressure greater than the resistance of the resistance rod 14, the air pressure pushes the air plug 15 on the surface of the resistance rod 14 to slide. When the air plug 15 slides to the groove of the inner tube 13, the air pressure moves to the outer tube 12 through the groove in the inner tube 13, and moves to the nozzle 7 through the air pipe 8. The compressed air flow is instantly released inside the frame 1, and the dust on the surface of the base 2 is blown away through the nozzle 7. When the cutter 5 starts shearing again, the compression rod 10 is reset under the elastic action of the spring 9, and the air plug 15 is reset under the resistance of the resistance rod 14. In addition, a one-way valve is provided inside the frame 1 to replenish the air inside the frame 1.
