Description

Technical Field

[0001] The invention relates to the field of metal processing, in particular to a trimming machine for processing a supporting skirt bottom end cap of a chemical container. Background Art

[0002] Nuclear reactor rods, also known as reactor fuel rods, are the source of nuclear fission materials in nuclear reactors. In nuclear reactors, the support skirt base provides stable support for the core and internal components. The main function of the support skirt base is to ensure the stability and safety of the nuclear reactor during operation. However, the support skirt bottom head and the support skirt base are important structural components in nuclear reactors or similar large-scale equipment. The relationship between them is mainly reflected in the three aspects of connection, support and sealing. The support skirt bottom head and the support skirt base are usually fixed together by welding or other high-strength connection methods. This connection method ensures a close connection between the two, thereby forming a stable and strong overall structure. However, the support skirt bottom head needs to go through the support skirt bottom head forming and trimming processes during the production process. In the process of trimming the support skirt bottom head, a special trimming machine is often required;

[0003] The trimming machine for processing the supporting skirt bottom head of chemical container is a kind of equipment specially used for metal processing. The supporting skirt bottom head is designed as a hemispherical shape. This shape can provide better stress distribution, reduce stress concentration, and thus improve the safety of the container. In addition, a cylindrical skirt is connected to one end of the head, and its upper end inner diameter is equal to the inner diameter of the connected tower shell head, which is used to support the entire container. The trimming machine for processing the supporting skirt bottom head of chemical container mainly cuts the part of the cylindrical skirt extension where the metal solution overflows during processing and the part of the metal solution dissolved during skirt welding;

[0004] The existing Chinese patent with publication number CN118218664A discloses a trimming machine for hardware production and processing, comprising: a driving component, a cutting component is fixedly installed inside the driving component, and an extrusion component is arranged inside the driving component and on the outer surface of the middle part of the cutting component; the cutting component is used to support the top cover of the hardware and drive the top cover of the hardware to rotate, and can perform trimming processing on the rotating top cover of the hardware; the extrusion component is used to transmit pressure inside the driving component so that the cutting structure inside the driving component supports operation; the present invention can perform continuous processing on the top cover of the hardware through the coordinated operation between the cutting component, the extrusion component and the driving component, improve the processing efficiency of the top cover of the hardware, and can automatically cut and remove the waste ring of the top cover of the hardware;

[0005] However, there are still the following defects:

[0006] The existing trimming machines do not have enough cutting precision and the cutting force is too great, so the edge of the head is prone to orange peel and bulging after trimming. The orange peel and bulging problems are caused by the one-time force applied during the stamping of the head. The excessive pressure on the plate causes the plate to become delaminated. In addition, due to inconsistent product sizes, traditional trimming methods may lead to too much or too little cutting area, which brings inconvenience to subsequent processes.

Since the arc cutter has been attached to the outer wall of the workpiece, the arc cutter is blocked, and the moving seat drives the top of the arc cutter to continue to move, so that the arc cutter can be tilted and rotated. When the Z-shaped slide bar moves downward to the maximum position, the arc cutter is tilted at 30 degrees, so that during the trimming process, the grinding surface provided on the inner side can be used to grind the position after trimming, so as to avoid the phenomenon of orange peel and bulging at the edge of the workpiece after trimming. At the same time, the arc cutter can be closely attached to the edge of the workpiece during the lateral movement, so as to achieve a better trimming effect.

[0025] Thirdly, the bottom fixed head support can also push the adjusting clamping plate to move according to the heads of different sizes to adjust the clamping force. When encountering a smaller head, push the adjusting clamping plate to the middle position of the head fixing bracket to strengthen the fixing effect of the clamping plate, so as to avoid the problem of head displacement due to incomplete fixation of the small head during the cutting process, thereby affecting the cutting accuracy. The adjusting clamping plate is distributed in a ring shape around the head fixing bracket, which can clamp the head in an all-round manner of 360 degrees, thereby strengthening the clamping effect of the head.

The first gear 304, the second gear 305 and the third gear 306 are driven by meshing. The first gear 304 and the second gear 305 drive the third gear 306 to rotate. The function of the two sets of transmission teeth is to improve the stability and accuracy of the transmission and effectively avoid tooth disengagement.

[0053] A transmission rod 307 is fixed to the top of the third gear 306, and the third gear 306 drives the transmission rod 307 to rotate. A head fixing bracket 311 is installed on the top of the transmission rod 307. The head is buckled on the top of the head fixing bracket 311, and the transmission rod 307 drives the head fixing bracket 311 on the top to rotate.

[0054] Among them, a fourth gear 308 is fixed at the top of the transmission rod 307 near the head fixing bracket 311, and a fifth gear 309 is installed on one side of the fourth gear 308. The fourth gear 308 at the top of the transmission rod 307 rotates counterclockwise to drive the fifth gear 309 to rotate clockwise.

In addition, the bottom fixed head support can also push the adjustment clamping plate 314 to move according to the different sizes of heads to adjust the clamping force. When encountering a smaller head, the adjustment clamping plate 314 is pushed to the middle position of the head fixing bracket 311 to strengthen the fixing effect of the clamping plate, so as to avoid the problem of head deviation due to incomplete fixation due to the small size of the head during the cutting process, thereby affecting the cutting accuracy. The adjustment clamping plate 314 is distributed in a ring shape around the head fixing bracket 311, which can clamp the head in an all-round way at 360 degrees, thereby strengthening the clamping effect of the head.

[0060] Working principle: first, place the end cap on the top of the end cap fixing bracket 311, then start the second motor 302 and the third motor 303 to drive the first gear 304 and the second gear 305 to rotate in the same direction, the first gear 304 and the second gear 305 drive the third gear 306 to rotate, the two sets of transmission teeth are used to improve the stability and accuracy of the transmission and effectively avoid tooth disengagement, then the third gear 306 drives the transmission rod 307 to rotate, the transmission rod 307 drives the end cap fixing bracket 311 at the top to rotate, when the end cap fixing bracket 311 rotates counterclockwise, it drives the adjusting clamp 314 to the middle of the end cap fixing bracket 311 The specific working principle is that the fourth gear 308 at the top of the transmission rod 307 rotates counterclockwise to drive the fifth gear 309 to rotate clockwise, and the fifth gear 309 drives the transmission gear ring 310 to rotate clockwise. When the transmission gear ring 310 rotates clockwise, it drives the adjustment clamping plate 314 to move along the trajectory of the guide groove 313, thereby driving the adjustment clamping plate 314 to clamp the head.

After the arc cutter 213 moves downward to the specified position, the drive motor 201 can be started, and the output end of the drive motor 201 drives the transmission rod 207 to drive the arc cutter 213 to rotate in a circle to trim the support skirt bottom end cap;

[0063] When the transmission rod 207 rotates, the double thread grooves arranged on the outer wall cooperate with the slider inside the movable slider 206, thereby driving the movable slider 206 to reciprocate up and down. When the movable slider 206 moves downward, the sliding ring 209 is pushed by the connecting sleeve 208 to drive the arc cutter 213 to move downward and squeeze the connecting spring 211. When the movable slider 206 moves upward to reset, the sliding ring 209 drives the arc cutter 213 to move upward to reset under the action of the connecting spring 211, so that the arc cutter 213 can float up and down, thereby effectively reducing the shaking caused by cutting, and more effectively cutting off the excess material on the edge of the workpiece, which helps to improve the cutting efficiency, shorten the processing time, and thus improve the overall practicality of the device;

[0064] The inner side of the arc cutter 213 can be provided with a grinding surface for grinding. When the sliding ring 209 drives the arc cutter 213 to move downward, the spherical rod 220 contacts the conical surface 214, and the movable seat 217 is pushed to move toward the workpiece under the action of the conical surface 214. Since the arc cutter 213 has been attached to the outer wall of the workpiece, the arc cutter 213 is blocked. The movable seat 217 drives the top of the arc cutter 213 to continue to move, so that the arc cutter 213 can be tilted and rotated. When the Z-shaped sliding rod 212 moves downward to the maximum position, the arc cutter 213 is inclined at thirty degrees. During the trimming process, the grinding surface provided on the inner side is used to grind the position after trimming, so as to avoid the phenomenon of orange peel and bulging at the edge of the workpiece after trimming. At the same time, the arc cutter 213 can be closely attached to the edge of the workpiece during the lateral movement, thereby achieving a better trimming effect.
