[0017] Step one, limiting process: the mold workpiece is placed on the support plate a and the support plate b by the mechanical arm, and the movable plates on the two groups of support plates are driven to move to the edge of the cutting position by the electric telescopic rod b, the movable plates are driven to move downward by the electric telescopic rod c, the edges of the cutting position on both sides of the mold workpiece are pressed tightly, and the magnetic force of the electromagnetic plates is given by the energization of the multiple electromagnetic seats in the electromagnetic box to limit and fix the mold workpiece;

[0018] Step two, the front initial cutting process: the whole side frame b is pushed to the support b by the electric telescopic rod d, so that the sliding frame is above the support b; then the height of the sliding frame and the cutting equipment is adjusted by the cylinder a; the transverse position of the cutting equipment is adjusted by the motor c driving the roller to rotate on the guide rail, and the beam is driven to move by friction to adjust the transverse position of the cutting equipment; the longitudinal position of the cutting equipment is adjusted by the cylinder b; finally, the height of the cutting equipment is finely adjusted by the motor d driving the screw to rotate; the cutting head is rotated by the stepping motor to contact the mold workpiece downward, and the mold workpiece is initially cut by the moving assembly;

[0019] Step three, the lower bending process: after the front initial cutting is completed, the motor a is driven clockwise, the reduction gear set is reduced, and the rotating wheel and the belt are driven to drive the movable block and the support plate b to deflect slightly along the movable seat on the support plate a, and the electric telescopic rod a drives one end of the two groups of pull rods a to move downward to the bottom end of the support plate a, the hydraulic cylinder pulls the pull rod b to retract, the pulling force is applied to one end of the support plate b through the movable connection of the pull rod b and the pin column on the support plate b, so that the bending force of the support plate b is further increased, and the workpiece plate is limited by the upper limiting assembly and is bent downward along the front cutting position to form a v-shaped notch;

[0020] Step four, the front secondary cutting process: the rotating disc is rotated again by the stepping motor, the cleaning rod and the drop nozzle are respectively downward and contact the v-shaped notch formed by bending, the v-shaped notch groove of the mold workpiece is cleaned by the cleaning rod cooperating with the moving assembly, the v-shaped notch groove of the mold workpiece is drop coated with the transmittance agent by the drop nozzle cooperating with the moving assembly, and the front secondary cutting is preferably performed in the v-shaped notch by the cutting head;

[0021] Step five, the back initial cutting process: the side frame b is pulled away from the support b by the electric telescopic rod d, the sliding frame is away from the support b, then the sliding frame and the cutting equipment are lowered by the cylinder a, and the sliding frame is below the support b, the sliding frame is pushed to the support b below by the electric telescopic rod d again, and the back of the mold workpiece is initially cut by the cutting groove on the support plate a and the support plate b after adjustment and rotation;

[0022] Step six, the upper bending process: after the back initial cutting is completed, the motor a is driven counterclockwise, a series of speed reduction transmissions are performed, the support plate b is deflected slightly upward, and the electric telescopic rod a drives one end of the two groups of pull rods a to move upward to the top end of the support plate a, so that the hydraulic cylinder applies a pulling force to one end of the support plate b upward, and the workpiece plate is bent upward along the back cutting position to form a v-shaped notch;

The repeated bending of the front and back of the workpiece causes metal fatigue, thereby improving the cutting efficiency. At the same time, the plasma cutting head is facilitated to enter for cutting, and the antireflection agent is facilitated to be dropped and applied to the cutting opening, thereby greatly improving the cutting efficiency of the device and being suitable for cutting workpieces with relatively thick thickness.

[0027] (2) The present application realizes the reciprocating and accurate cutting of the mold workpiece by the multiple moving adjustment mechanisms in the cutting mechanism and the horizontal and vertical moving assemblies, and realizes the front and back cutting of the workpiece by the motor setting of the traction assembly and the rotating adjustment function head, and further improves the cutting effect by setting the cleaning, antireflection and cutting in one.

[0028] (3) The present application realizes the conduction of heat during the cutting of the workpiece by the contact of the heat-conducting square tube with the cutting part of the workpiece. The pump in the cooling liquid station provides low-temperature cooling liquid for the heat-conducting square tube through the liquid filling pipe to replace the high-temperature cooling liquid after heating. The high-temperature cooling liquid is returned to the cooling liquid station through the liquid outlet pipe, blocked by the multiple staggered distribution of the flow extension plate, and cooled by the contact of air and the heat dissipation of the air fan. The cooled cooling liquid is accumulated at the bottom of the cooling liquid station for circulation and utilization, so as to realize the efficient cooling of the cutting part of the workpiece and avoid the workpiece loss caused by the change of the molecular structure of the plate caused by high temperature.

[0074] Example 2: Figures 1-22 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0075] A cutting method for a plasma cutting device for fine blanking dies includes the following steps:

[0076] Step 1, Limiting Operation: The robotic arm places the mold workpiece on support plate a302 and support plate b303, and the electric telescopic rod b333 drives the movable plate 332 on the two sets of support plates to move to the edge of the cutting area. The electric telescopic rod c336 drives the movable plate 332 to move down and press the two sides of the cutting area of ​​the mold workpiece. The electromagnetic plate 339 is given magnetic force by the multiple sets of electromagnetic seats 338 in the electromagnetic box 337 to limit and fix the mold workpiece.

[0077] Step two, front initial cutting process: the whole side frame b401 is pushed to move towards the support b301 by the electric telescopic rod d413, so that the sliding frame 402 is above the support b301; then the height of the sliding frame 402 and the cutting equipment is adjusted by the air cylinder a421; the transverse position of the cutting equipment is adjusted by the motor c432 driving the roller 433 to rotate on the guide rail 434, and the cutting equipment is driven to move by friction; the longitudinal position of the cutting equipment is adjusted by the air cylinder b442, and finally the height of the cutting equipment is finely adjusted by the motor d443 driving the screw 444 to rotate; the cutting head 456 is rotated by the stepping motor 454 to make the cutting head 456 contact the mold workpiece downward, and the mold workpiece is initially cut by the moving assembly;

[0078] Step three, lower bending process: after the front initial cutting is completed, the movable block 307 and the support plate b303 are driven to deflect along the movable seat 308 on the support plate a302 by the clockwise driving of the motor a312, the reduction gear set 313, the transmission of the rotating wheel 315 and the belt 316, and the one end of the two groups of pull rods a324 is driven to move downward to the bottom end of the support plate a302 by the electric telescopic rod a329, the pull rod b325 is retracted by the hydraulic cylinder 327, the pulling force is applied to one end of the support plate b303 through the movable connection of the pull rod b325 and the pin column 326 on the support plate b303, so that the bending degree of the support plate b303 is further increased, and the workpiece plate is limited by the upper limiting assembly, and a small amplitude bending is formed along the front cutting to form a v-shaped notch;

[0079] Step four, front secondary cutting process: the cleaning rod 457 and the drop nozzle 458 are rotated again by the stepping motor 454, and are contacted with the v-shaped notch formed by bending downward, the v-shaped notch groove of the mold workpiece is cleaned by the cleaning rod 457 cooperating with the moving assembly, the v-shaped notch groove of the mold workpiece is drop coated with the transmittance agent by the drop nozzle 458 cooperating with the moving assembly, and the front secondary cutting is preferably performed in the v-shaped notch by the cutting head 456;

[0080] Step five, back initial cutting process: the whole side frame b401 is driven away from the support b301 by the electric telescopic rod d413, so that the sliding frame 402 is away from the support b301, then the sliding frame 402 and the cutting equipment are lowered and are below the support b301 by the air cylinder a421, the sliding frame 402 is pushed to the lower side of the support b301 by the electric telescopic rod d413 again, and the back of the mold workpiece is initially cut by the cutting groove 306 on the support plate a302 and the support plate b303 after adjustment and rotation;

[0081] Step Six, Upper Bending Process: After the initial cut on the back side is completed, the drive motor a312 rotates counterclockwise. After a series of reduction transmissions, it drives the support plate b303 to deflect slightly upward. At the same time, the electric telescopic rod a329 drives one end of the two sets of tie rods a324 to move upward to the top of the support plate a302. This causes the hydraulic cylinder 327 to apply a pulling force upward at one end of the support plate b303, causing the workpiece plate to bend slightly upward along the cut on the back side to form a V-shaped notch.

[0082] Step 7, Secondary Cutting Process on the Back Side: Similarly, using the cutting head 456, cleaning rod 457, and nozzle 458, clean, enhance the transparency, and cut the bent area on the back side. Repeating this process multiple times will cut through thicker mold workpieces.

[0083] Step 8, Cooling Process: The low-temperature coolant at the bottom of the coolant station 344 is drawn out by the circulating pump 345 and injected into the heat-conducting square tube 341 through the filling pipe 346. The heat-conducting square tube 341 and the multiple sets of heat-conducting fins 342 at the bottom contact the mold workpiece to cool the cut part of the workpiece. After heat exchange, the coolant with a higher temperature flows back to the coolant station 344 through the outlet pipe 347. The high-temperature coolant is cooled by the flow obstruction of multiple sets of staggered flow plates 351 and the air exchange of the upper fan 355. The cooled coolant will accumulate at the bottom of the coolant station 344 and be drawn out by the back circulating pump 345 for circulation cooling.

[0084] It should be noted that: In this embodiment, a thicker mold plate is cut by bending it up and down multiple times. The first cut creates a notch in the mold plate, and then the mold plate is bent (the angle should not be too large). The resulting notch is V-shaped. A penetration enhancer is applied to the V-shaped notch and the notch is cleaned. The cutting equipment then makes a second cut at the V-shaped notch. Cleaning and applying the penetration enhancer enhance the plasma laser cutting effect. Next, the cutting equipment is moved to cut the same position on the back of the workpiece. After cutting, the workpiece is bent, and penetration enhancer is applied and cleaned. The operation is repeated, gradually increasing the angle of the V-shaped notch and then gradually flipping the cut. Increasing the angle of the V-shaped notch facilitates the penetration enhancer to flow to the bottom of the notch and also makes it easier for the cutting equipment to insert into the V-shaped notch for another cut. This process is repeated multiple times until the thicker mold plate is cut off.

[0085] This embodiment allows for single-sided bending and cutting, reciprocating bending and cutting, and reciprocating breaking of thicker mold plates.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
