Description

Technical Field

[0001] The invention relates to the technical field of steel plate processing, and in particular to a trimming device for steel plate processing. Background Art

[0002] The nuclear reactor rod electrothermal simulation container is an experimental device used to simulate the heating process of nuclear reactor fuel rods. The electrothermal simulation container uses high thermal conductivity insulating materials to effectively conduct heat while maintaining electrical safety. The electrothermal simulation container uses built-in electric heating elements. The simulation container can simulate the thermal state in the nuclear reactor without an actual nuclear reaction. The simulation container is equipped with a precise temperature control system and monitoring equipment to ensure the accuracy and repeatability of the experimental conditions. The nuclear reactor rod electrothermal simulation container consists of an outer shell cylinder and a hanging basket arranged inside it. The outer shell cylinder is composed of inner and outer cylinders (including internal isolation and insulation layer + support skirt), top cover flange, top cover connecting high-strength studs, high-pressure pipe seals, sealing structures and flat top covers. When manufacturing the bottom head of the support skirt, the steel plate needs to be trimmed after forming.

[0003] The current conventional steel plate trimming device lacks inert gas protection. During the high-temperature cutting process, the steel plate is easily oxidized by the oxygen in the air to form an oxide layer. This will not only reduce the quality of the cut edge, causing oxidation and discoloration, but may also lead to a decrease in cutting accuracy. The heat generated by the oxidation reaction will further affect the cutting area, increase the heat-affected zone, and cause changes in material properties. The existing steel plate trimming device cannot adjust the cooling speed according to the heating of the tool. During the high-temperature cutting process, the temperature of the tool will rise rapidly. If the cooling speed cannot be adjusted in time according to the heating of the tool, the tool may accelerate wear due to overheating. This will not only shorten the service life of the tool, but may also cause interruptions in the cutting process and affect production efficiency; therefore, we propose a steel plate processing trimming device to solve this problem.

[0022] The beneficial effects of the present invention are:

[0023] 1. In the present invention, the described steel plate processing trimming device is arranged by placing the steel plate to be trimmed on the top of the mounting frame and adjusting the horizontal position of the steel plate to align the cutting knife, then pulling the handle to drive the pull rod and the positioning pin to move horizontally, so that the positioning pin is pulled out of the positioning slot, releasing the lock of the rotating disk and the bidirectional screw, and then rotating the knob to drive the bidirectional screw to rotate, the bidirectional screw drives the two horizontal plates away from each other through the threaded engagement with the two linkage plates and under the guidance of the crossbeam, the two horizontal plates drive the two clamping plates to move downward through the engagement with the corresponding arc-shaped connecting plates, and the steel plates are pressed and fixed by the clamping plates;

[0024] 2. In the present invention, the described steel plate processing trimming device drives the crankshaft and the rotating shaft to rotate synchronously by starting the rotating motor, and the rotating shaft drives the cutting knife to rotate while rotating, and the two screw rods are driven to rotate synchronously by starting the driving motor, and the screw rods drive the connecting frame and the mounting box to move forward and backward by cooperating with the threads of the driving plate, thereby driving the high-speed rotating cutting knife to move forward and backward, so as to realize automatic trimming of the steel plate;

[0025] 3. In the present invention, the trimming device for steel plate processing drives the piston plate to move up and down reciprocatingly through the cooperation of the crankshaft and the connecting plate. The piston plate cooperates with the first one-way valve and the second one-way valve so that when the piston plate moves upward, the cutting fluid pre-stored in the bottom frame can be extracted through the water inlet pipe and introduced into the atomizing nozzle through the water outlet pipe. The atomizing nozzle sprays the cutting fluid in atomization to achieve cooling of the cutting knife. The used cutting fluid flows down through the filter screen and flows back into the bottom frame through the water outlet to achieve recycling of the cutting fluid. The temperature of the used cutting fluid is detected by the thermistor. When the cutting knife generates a lot of heat, causing the temperature of the cutting fluid to rise significantly, the temperature of the thermistor rises accordingly, increasing its resistance, thereby reducing the operating power of the drive motor to reduce the speed of the cutting knife feeding forward and backward to avoid overheating of the cutting knife.

[0026] 4. In the present invention, the described steel plate processing trimming device drives the rotating ring to rotate synchronously through the rotating shaft, and the rotating ring drives multiple inclined rods to perform circular motion during rotation, so that the inclined rods move outward under the action of centrifugal force and move horizontally at the same time. The inclined rods drive the rotating drum to rotate and move horizontally at the same time by cooperating with the vertical rods. The rotating drum drives the cylinder to move horizontally by cooperating with the two limiting protrusions. The cylinder drives the sealing plate to move horizontally and realizes the extrusion of the compression spring. After the moving plate moves to a certain distance, the air inlet pipe is connected with the injection pipe, and the inert gas stored in the compression tank is sprayed toward the contact position between the cutting knife and the steel plate through the air inlet pipe and the injection pipe, thereby forming an inert gas protection at the contact position to prevent the cutting surface of the steel plate from being oxidized by high temperature and oxygen. The greater the rotation speed of the cutting knife, the greater the centrifugal force on the inclined rod, thereby making the sealing plate move a greater distance, and the larger the conduction cross-sectional area between the air inlet pipe and the injection pipe, thereby making the injection volume larger, so as to ensure the protection effect of the steel plate;

[0027] 5. In the present invention, the trimming device for steel plate processing can utilize the driving force of the cutting knife to spray the cutting fluid through the provided cooling mechanism, thereby realizing cooling of the cutting knife. This not only simplifies the driving mechanism and reduces the equipment cost, but also makes the spraying speed of the cutting fluid linearly related to the rotation speed of the cutting knife. The provided jet mechanism can spray inert gas during cutting to provide anti-oxidation protection for the steel plate, and the spraying amount of the inert gas can be linearly related to the rotation speed of the cutting knife, that is, the faster the rotation speed of the cutting knife, the greater the spraying amount of the cutting fluid and the inert gas, thereby ensuring the cooling and anti-oxidation effects. When the cutting knife generates a large amount of heat, the horizontal feed speed of the cutting knife can be reduced to avoid damage caused by overheating of the cutting knife, thereby extending the service life of the cutting knife.

The air pipe 608 is connected, and the inert gas stored in the compressed storage tank 9 is sprayed toward the contact position between the cutting knife 402 and the steel plate through the air inlet pipe 606 and the jet pipe 608, thereby forming an inert gas protection at the contact position to prevent the cut surface of the steel plate from oxidizing due to high temperature and oxygen. The greater the rotation speed of the cutting knife 402, the greater the centrifugal force on the inclined rod 607, and the greater the moving distance of the sealing plate 609, and the larger the conducting cross-sectional area between the air inlet pipe 606 and the jet pipe 608, so that the jet volume is larger, so as to ensure the protection effect of the steel plate.
