Description

Technical Field

[0001] The present invention relates to the technical field of molybdenum disc cutting, and more specifically, to a surface cutting device for molybdenum disc processing. Background Art

[0002] Molybdenum is a metal element with high temperature resistance. Adding molybdenum to alloy steel can improve the elastic limit, corrosion resistance and permanent magnetism of the metal. The packaging of ultra-high power thyristors adopts the press-bonding process. The chips of high-voltage and high-current semiconductor devices are all equipped with alloy molybdenum discs and are packaged in ceramic tube shells using full press-bonding technology. Therefore, the molybdenum discs need to be processed in a series of ways before use, including cutting. According to the patent document with patent number CN106735592A, the molybdenum disc is fully cut by using ultra-high water flow cutting technology, so that the surface of the molybdenum disc after cutting is smoother. However, due to the high thermal conductivity of the molybdenum disc, the heat generated during the cutting process is not easy to dissipate, which can easily cause the workpiece to overheat, which not only affects the performance and life of the cutting tool, but also may affect the processing accuracy and surface quality. It is impossible to immerse the bottom of the molybdenum disc in the cutting process to cool it down, and cooperate with the spraying of cutting fluid to achieve the best cooling effect; In view of the above technical defects, a solution is now provided. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a surface cutting device for molybdenum disc processing.

[0004] To achieve the above object, the present invention provides the following technical solution: a surface cutting device for processing molybdenum discs, comprising a support frame, a cutting pool is fixedly connected to the top of the support frame, a cutting frame is slidably arranged in the cutting pool, and a gathering mechanism for gathering cutting debris and a cooling mechanism for cooling the molybdenum disc are respectively arranged on both sides of the cutting frame; The gathering mechanism includes two groups of stacking openings opened at the bottom of the cutting frame, a scraper is slidably arranged on the top of the cutting frame, and two gathering connecting plates are symmetrically arranged on the side wall of the scraper; The cooling mechanism comprises a transverse groove opened at the bottom of the cutting frame, the transverse groove is located in the middle of the material stacking opening, and an interception plate is slidably arranged inside the transverse groove.

[0005] Furthermore, the ends of the two gathering connection plates extend to the outside of the cutting frame and are commonly connected to a gathering pressing plate, and a plurality of thrust springs are arranged on the side walls of the gathering pressing plate opposite to the cutting frame, and a mesh frame is clamped at the bottom of the cutting frame.

[0006] Furthermore, two connecting plates 2 are fixedly provided on one side of the intercepting plate, the ends of the two connecting plates 2 are commonly connected to a pressing plate 2, and a plurality of thrust springs 2 are provided on the side of the pressing plate 2 opposite to the cutting frame.

[0007] Furthermore, two material discharge openings are provided on the outer wall of the intercepting plate, and the material discharge openings correspond to the material stacking openings.

[0008] Furthermore, a fixing frame is fixedly connected to the upper part of the interior of the cutting frame, and connecting plates three are fixedly provided at the corners around the fixing frame. A threaded rod one is threadedly connected to the connecting plate three, a fixing block is provided at one end of the threaded rod one, and a turning knob is provided at the other end of the threaded rod one.

[0009] Furthermore, the back of the cutting pool is fixedly connected with a side plate, the top of the side plate is fixedly connected with a top plate, and an upper moving part is arranged above the top plate.

[0010] Furthermore, a cylinder is connected below the upper moving member, an output end of the cylinder is fixedly connected to a cutting head via a transverse plate, and a spray head is provided on one side of the cutting head.

[0011] Furthermore, a drainage pipe is inserted into the bottom of the cutting pool, and the drainage pipe passes through the support frame and extends to the outside thereof.

[0012] Wherein, the working method of the surface cutting equipment for molybdenum disc processing comprises the following steps: Step 1: First, place the molybdenum disc on the cutting frame, and control the rotation to move the threaded rod, and limit and fix the molybdenum disc through the fixing block; Step 2: Then the upper surface of the molybdenum disc is cut by the cutting head. During the cutting process, the cutting fluid is continuously sprayed; and the cutting pool and the cylinder are continuously moved forward, backward, left and right. When the cutting frame in the cutting pool is discontinuously moved to one side, the gathering pressing plate discontinuously pushes the scraper to one side, and all the cutting debris in the cutting frame is pushed to the inside of the two stacking ports. As the molybdenum disc is continuously cut, the inside of the cutting frame is gradually filled with cutting fluid, so that the bottom of the molybdenum disc is immersed in the cutting fluid for cooling; Step 3: When the cutting frame moves back and forth intermittently to the other side, the pressing plate 2 is continuously squeezed, causing the intercepting plate to move intermittently to one side. When the unloading port on the intercepting plate is aligned with the stacking port, the cutting debris inside the stacking port enters the mesh frame, and the remaining cutting fluid is recovered by the cutting pool.

[0013] Technical effects and advantages of the present invention: 1. The present invention is that during the process of the cutting frame in the cutting pool reciprocating to one side, the gathering and pressing plate is continuously squeezed, so that the gathering and pressing plate pushes the scraper reciprocating to one side, and all the cutting debris on the upper part of the cutting frame are pushed to the inside of the two stockpiling ports, and as the molybdenum disc is continuously cut, the inside of the cutting frame is gradually filled with cutting fluid, so that the bottom of the molybdenum disc is immersed in the cutting fluid, and the best cooling effect is achieved with the spraying of the cutting fluid, so as to avoid the problem that the heat generated during the cutting process is not easy to dissipate due to the high thermal conductivity of the molybdenum disc, which easily leads to overheating of the workpiece, not only affecting the performance and life of the cutting tool, but also affecting the processing accuracy and surface quality.

[0014] 2. The present invention is that during the reciprocating movement of the cutting frame to the other side, the pressing plate 2 is continuously squeezed, causing the intercepting plate to intermittently move to one side. When the discharge port on the intercepting plate is aligned with the stacking port, the cutting debris inside the stacking port enters the mesh frame, and the remaining cutting fluid is recovered by the cutting pool. In the cutting process, the cutting fluid and cutting debris are directly classified and recovered, thereby improving the recovery efficiency of the waste cutting fluid. The interior of the cutting frame is intermittently filled with cutting fluid, so that the cutting fluid inside the cutting frame is always maintained at a relatively low temperature state, thereby ensuring the cooling effect.

[0025] According to the present invention, in combination with the first and second embodiments, the collection and pressing plate 61 is continuously squeezed during the continuous forward, backward, left and right movement of the cutting pool 2 and the cylinder 14, and the collection and pressing plate 61 pushes the scraper 64 to one side to push all the cutting debris on the upper part of the cutting frame 8 to the inside of the two stacking ports 65. As the molybdenum disc is continuously cut, the inside of the cutting frame 8 is gradually filled with cutting fluid, so that the bottom of the molybdenum disc is immersed in the cutting fluid, and the best cooling effect is achieved with the spraying of the cutting fluid. The pressing plate 2 71 is also continuously squeezed, causing the intercepting plate 74 to move intermittently to one side. When the discharge port 75 on the intercepting plate 74 is aligned with the stacking port 65, the cutting chips inside the stacking port 65 enter the mesh frame 66, and the remaining cutting fluid is recovered by the cutting pool 2, and the cutting fluid and cutting chips are directly classified and recovered during the cutting process.

During the cutting process, the cutting fluid is continuously sprayed to reduce the temperature of the surface of the molybdenum disc. At the same time, the cutting pool 2 and the cylinder 14 are continuously moved forward, backward, left and right. When the cutting frame 8 in the cutting pool 2 moves back and forth to one side, the gathering and pressing plate 61 is continuously squeezed, so that the gathering and pressing plate 61 pushes the scraper 64 back and forth to one side, and all the cutting debris on the upper part of the cutting frame 8 is pushed to the inside of the two stacking ports 65. As the molybdenum disc is continuously cut, the inside of the cutting frame 8 is gradually filled with cutting fluid, so that the bottom of the molybdenum disc is immersed in the cutting fluid. With the spraying of the cutting fluid, the best cooling effect is achieved to avoid the high thermal conductivity of the molybdenum disc, and the heat generated during the cutting process is not easy to dissipate, which easily leads to overheating of the workpiece, which not only affects the performance and life of the cutting tool, but also affects the processing accuracy and surface quality. Step 3: When the cutting frame 8 reciprocates to the other side, the pressing plate 2 71 is constantly squeezed, so that the intercepting plate 74 moves intermittently to one side. When the unloading port 75 on the intercepting plate 74 is aligned with the stacking port 65, the cutting debris inside the stacking port 65 enters the mesh frame 66, and the remaining cutting fluid is recovered by the cutting pool 2. In the cutting process, the cutting fluid and the cutting debris are directly classified and recovered, thereby improving the recovery efficiency of the waste cutting fluid; and the interior of the cutting frame 8 is intermittently filled with cutting fluid, so that the cutting fluid inside the cutting frame 8 is always kept at a relatively low temperature state, ensuring the cooling effect; Step 4: A control valve is provided on the outer wall of the drain pipe 9. When the control valve is opened, the cutting fluid in the cutting pool 2 is discharged through the control valve, thereby realizing the recovery and subsequent treatment of the cutting fluid.
