Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic system heating, and particularly relates to a heating device for a hydraulic system of a shearing machine. Background Art

[0002] At present, many shearing machines are equipped with a hydraulic system. The hydraulic oil plays roles such as energy transfer, anti-wear, system lubrication, anti-corrosion, rust prevention, and cooling in the hydraulic system. Each type of hydraulic oil has a certain range of use. Excessive or too low temperature has an adverse impact on the hydraulic oil. If the viscosity of the hydraulic oil is too low, the working efficiency of the hydraulic system will decrease. The current hydraulic system has a reduced ability to circulate and heat the hydraulic oil, and the heating is uneven. Therefore, we propose a heating device for a hydraulic system of a shearing machine. Summary of the Invention

[0003] The purpose of the invention is to provide a heating device for a hydraulic system of a shearing machine, which continuously generates friction through the movement of a hydraulic rod, and drives the friction between a friction block and a friction frame to generate heat when sucking and discharging oil, thus solving the existing problems.

[0004] To solve the above technical problems, the invention is realized through the following technical solutions: The invention is a heating device for a hydraulic system of a shearing machine, including a shearing machine, a feeding port, an opening and closing door, and legs. Legs are arranged at the four corners of the bottom of the shearing machine. The opening and closing door is hinged to the front of the shearing machine. Feeding ports are provided at the left and right centers of the shearing machine. The shearing machine includes a hydraulic rod, an oil discharging mechanism, a suction block, an oil storage tank, a straight rod, a pressing plate mechanism, a bottom plate, and a cutting knife. Bottom plates are fixedly connected to the left and right inner walls of the shearing machine. Hydraulic rods are fixedly connected to the upper and lower inner walls of the shearing machine. The oil storage tanks are communicated with the left and right of the two hydraulic rods. Cutting knives are fixedly connected to the mutually close ends of the two hydraulic rods. Straight rods are fixedly connected to the left and right ends of the cutting knife at the top of the two cutting knives. The pressing plate mechanisms are arranged at the bottoms of the two straight rods. The suction blocks are arranged inside the mutually far ends of the two hydraulic rods. The two suction blocks are fixedly connected to the outer surfaces of the output ends of the hydraulic rods. The oil discharging mechanisms are arranged at the mutually far ends of the two suction blocks. The work of the hydraulic rod drives the cutting knife to perform cutting work. When the material enters the inside of the shearing machine through the feeding port, the bottom plate will position and support the material. When the hydraulic rod works, the suction block will reciprocate inside the hydraulic rod to enhance the effect of oil suction and oil discharge inside the hydraulic rod.

[0005] Further, the pressing plate mechanism includes a vertical rod, a base frame, a movable block, a sliding hole, and an arc pressing rod. The top of the vertical rod is fixedly connected to the bottom of the straight rod. The base frame contacts the outer surface of the vertical rod. The vertical rod penetrates through the top of the base frame and extends into the interior of the base frame. The bottom of the vertical rod is fixedly connected to the movable block. Sliding holes are formed at both the left and right ends of the base frame. Both the left and right ends of the arc pressing rod contact the inner walls of the two sliding holes.

[0006] Further, the oil outlet mechanism includes elastic rods, movable rods, grooves, a stirring mechanism, an oil outlet pipe, a moving frame, a friction frame, friction blocks, a moving plate, and a connecting rod. There are two elastic rods. Both of the two elastic rods are fixedly connected to the bottom of the inner wall of the hydraulic rod. One end of both of the two elastic rods away from the hydraulic rod is fixedly connected to the moving plate. Oil outlet openings are formed at both the left and right ends of the moving plate. A moving frame is fixedly connected to the center of one end of the moving plate close to the two elastic rods. Grooves are formed at the bottom of the inner walls of the hydraulic rod. Movable rods are fixedly connected to the bottom of the inner walls of the grooves. The bottom of the movable rod is fixedly connected to the connecting rod. The connecting rod penetrates through the top of the moving frame and extends into the interior of the moving frame. A stirring mechanism is arranged at the top of the inner wall of the moving frame. Friction frames are fixedly connected to both the left and right inner walls of the moving frame. The left and right ends of the friction blocks contact the outer surfaces of the two friction frames. The top of the friction block is fixedly connected to the bottom of the connecting rod. The oil outlet pipe is communicated with the bottom of the hydraulic rod. When the hydraulic rod moves, the suction block inside will reciprocate with the output end of the hydraulic rod. The effect of oil suction and oil outlet is achieved through the suction and thrust of the suction block. The suction block can squeeze the moving plate, and the moving plate will reciprocate through the elastic rods. The reciprocating movement of the moving plate can make the connecting rod reciprocate inside the moving frame along with the moving plate.

[0007] Further, the stirring mechanism includes a threaded block, stirring rods, elastic sheets, a movable plate, and rolling balls. The threaded block is rotatably connected to the top of the inner wall of the moving frame through a bearing. The threaded block is threadedly connected to the outer surface of the connecting rod. Stirring rods are fixedly connected to both the left and right outer surfaces of the threaded block. Elastic sheets are fixedly connected to the inner walls of the ends of the two stirring rods away from each other. A movable plate is fixedly connected to one end of both of the two elastic sheets close to each other. Rolling balls are arranged inside both of the two stirring rods. When the stirring rods move, the rolling balls inside will move inside the stirring rods through centrifugal force, and the rolling balls will reciprocate back and forth through the elasticity of the elastic sheets.

[0008] Further, the friction block includes a thrust spring, a vertical rod, an inner groove, an impact block, a semi-circular rod, a sliding groove heat block, and a sliding groove block. An inner groove is formed inside the friction block. The left, right, upper, and lower inner walls of the inner groove are fixedly connected with sliding groove blocks. Sliding groove heat blocks are arranged inside the four sliding groove blocks. Vertical rods are fixedly connected to the upper and lower ends of the four sliding groove heat blocks close to each other. Thrust springs are fixedly connected to the ends of the two vertical rods away from each other. Semi-circular rods are fixedly connected to the ends of the two vertical rods close to each other. An impact block is arranged inside the inner groove.

[0009] Further, the top outer surfaces of the two bottom plates are perpendicular to the bottom of the arc-shaped pressing rod. Shearing cuts are provided at the ends of the two bottom plates close to each other.

[0010] Further, the top of the oil outlet pipe is communicated with the inside of the oil storage tank. The moving frame is adapted to the inside of the groove.

[0011] The present invention has the following beneficial effects: When the cutting knife moves downward for cutting in the present invention, the bottom frames at both ends of the cutting knife will contact the surface of the material. The vertical rod will push the movable block inside the bottom frame downward through the downward pressure of the cutting knife, and the movable block will squeeze the arc-shaped pressing rod to fix the material, preventing the material from curling under a large force during cutting.

[0012] In the present invention, since the movable block can move up and down inside the bottom frame, the arc-shaped bottom rod can slowly press the material through the movement of the cutting knife. If it directly contacts the material, continuous pressing by the cutting knife will damage the surface of the material.

[0013] In the present invention, when the moving plate is under the pressure of the suction block, the moving frame will contract into the inside of the groove following the movement of the moving plate. The contraction of the moving frame enables the moving plate to better fit tightly with the bottom of the inner wall of the hydraulic rod, allowing the moving plate to push the hydraulic oil inside the hydraulic rod into the oil storage tank through the oil outlet pipe, enhancing the oil outlet effect inside the hydraulic rod.

[0014] In the present invention, when the moving frame moves, the connecting rod will drive the friction block to perform a reciprocating friction movement inside the friction frame. The heat generated by the friction will be transmitted to the inside of the hydraulic oil through the stirring rod, preventing the working efficiency of the hydraulic rod from decreasing due to the increased viscosity of the hydraulic oil at a low temperature.

[0015] In the present invention, when the rolling ball moves inside the stirring rod, it will generate vibrations. While the stirring rod stirs the hydraulic oil inside, the vibrations will increase the activity of the hydraulic oil.

[0016] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. Brief Description of the Drawings

[0023] The pressing plate mechanism 15 includes a vertical rod 151, a bottom frame 152, a movable block 153, a sliding hole 154, and an arc pressing rod 155. The top of the vertical rod 151 is fixedly connected to the bottom of the straight rod 14. The bottom frame 152 is in contact with the outer surface of the vertical rod 151.

[0024] The oil outlet mechanism 11 includes elastic rods 110, movable rods 111, grooves 112, a stirring mechanism 113, an oil outlet pipe 114, a moving frame 115, a friction frame 116, friction blocks 117, a moving plate 118, and a connecting rod 119. There are two elastic rods 110, and both of the two elastic rods 110 are fixedly connected to the bottom of the inner wall of the hydraulic rod 10. One end of the two elastic rods 110 away from the hydraulic rod 10 is fixedly connected to a moving plate 118. Oil outlet openings are provided at the left and right ends of the moving plate 118. At the center of one end of the moving plate 118 close to the two elastic rods 110, a moving frame 115 is fixedly connected. Grooves 112 are provided at the bottom of the inner wall of the hydraulic rod 10, and movable rods 111 are fixedly connected to the bottom of the inner walls of the grooves 112. A connecting rod 119 is fixedly connected to the bottom of the movable rod 111. The connecting rod 119 penetrates through the top of the moving frame 115 and extends into the interior of the moving frame 115. A stirring mechanism 113 is provided on the top inner wall of the moving frame 115. Friction frames 116 are fixedly connected to the left and right inner walls of the moving frame 115. The left and right ends of the friction blocks 117 are in contact with the outer surfaces of the two friction frames 166, and the top of the friction block 117 is fixedly connected to the bottom of the connecting rod 119. The oil outlet pipe 114 is communicated with the bottom of the hydraulic rod 10. In the invention, when the moving plate 118 is subjected to the pressure of the suction block 12, the moving frame 115 will contract into the interior of the groove 112 following the movement of the moving plate 118. Through the contraction of the moving frame 115, the moving plate 118 can better tightly fit with the bottom of the inner wall of the hydraulic rod 10, so that the moving plate 118 can push the hydraulic oil inside the hydraulic rod into the interior of the storage tank 13 through the oil outlet pipe 114, enhancing the oil outlet effect inside the hydraulic rod 10.

[0025] The stirring mechanism 113 includes a threaded block b1, a stirring rod b2, an elastic piece b3, a movable plate b4, and a rolling ball b5. The threaded block b1 is rotatably connected to the top inner wall of the moving frame 115 through a bearing. The threaded block b1 is threadedly connected to the outer surface of the connecting rod 119. Stirring rods b2 are fixedly connected to the left and right outer surfaces of the threaded block b1. Elastic pieces b3 are fixedly connected to the inner walls of the ends of the two stirring rods b2 away from each other. Movable plates b4 are fixedly connected to the ends of the two elastic pieces b3 close to each other. Rolling balls b5 are provided inside the two stirring rods b2. In the present invention, when the rolling balls b5 move inside the stirring rods b2, vibrations will be generated. While the stirring rods b2 stir in the hydraulic oil, the activity of the hydraulic oil is increased through the vibrations.

[0026] The friction block 117 includes a thrust spring c1, a vertical rod c2, an inner groove c3, an impact block c4, a semi-circular rod c5, a chute heat block c6, and a chute block c7. An inner groove c3 is formed inside the friction block 117. Chute blocks c7 are fixedly connected to the left, right, upper, and lower inner walls of the inner groove c3. Chute heat blocks c6 are arranged inside the four chute blocks c7. Vertical rods c2 are fixedly connected to the upper and lower ends of the four chute heat blocks c6 that are close to each other. Thrust springs c1 are fixedly connected to the ends of the two vertical rods c2 that are away from each other. Semi-circular rods c5 are fixedly connected to the ends of the two vertical rods c2 that are close to each other. An impact block c4 is arranged inside the inner groove c3. In the present invention, when the moving frame 115 moves, the connecting rod 119 drives the friction block 117 to perform reciprocating friction movement inside the friction frame 116. The heat generated by the friction is transmitted to the inside of the hydraulic oil through the stirring rod b2, preventing the working efficiency of the hydraulic rod 10 from decreasing due to the increased viscosity of the hydraulic oil at a low temperature.

[0027] The top outer surfaces of the two bottom plates 16 are perpendicular to the bottom of the arc pressing rod 155. Shearing cuts are provided at one ends of the two bottom plates 16 that are close to each other.

[0028] The top of the oil outlet pipe 114 communicates with the inside of the oil storage tank 13. The moving frame 115 is adapted to the inside of the groove 112.

[0029] A specific application of this embodiment is as follows: When the hydraulic rod 10 moves, the output end of the hydraulic rod 10 drives the cutting knife 17 to cut the material. When the cutting knife 17 contacts the bottom plate 16, the bottom frame 152 contacts the surface of the material. When the cutting knife 17 presses down, the vertical rod 151 presses down the arc pressing rod 155 through the movable block 153, and the material is squeezed and fixed by the arc pressing plate 155. When the hydraulic rod 10 works, it drives the suction block 12 to move inside the hydraulic rod 10. When the hydraulic rod 10 retracts, it squeezes the surface of the moving plate 118, and the internal hydraulic oil enters the inside of the moving plate 118 through the oil outlet. When the suction block 12 squeezes the surface of the moving plate 118, it blocks the oil outlet, enabling the moving plate 118 to push the hydraulic oil into the oil storage tank through the oil outlet pipe 114 by extrusion. When the moving plate 118 moves, the internal connecting rod 119 is pushed into the inside of the moving frame 115. When the connecting rod 119 moves, it drives the stirring rod b2 to rotate through the threaded block b1. The rolling ball b5 inside the stirring rod b2 moves inside the stirring rod b2 by the rotational force. When the connecting rod 119 is inside the moving frame 115, it drives the friction block 117 to perform friction inside the friction frame 116. The elastic rod 110 drives the moving plate 118 to push the connecting rod 119, causing the connecting rod 119 to drive the friction block 117 to perform reciprocating movement inside the friction frame 115.
