[0001] The present application relates to the technical field of die production, and more particularly to a laser cutting equipment for stamping die production. BACKGROUND

[0002] The stamping die is a special equipment for machining, and is an equipment for processing materials into parts in cold stamping. Stamping is a pressure processing method for separating and plastic deformation of materials at room temperature by using a die installed on a press.

[0003] In the process of producing and manufacturing the stamping die, the laser cutting method is used. When the stamping die is processed and formed, the die plate of the stamping die is usually thick. In order to reduce the heat affected zone and avoid cutting deformation and ensure the stability of cutting, the extrusion die to be cut is usually preheated when laser cutting is performed. However, in the prior art, when the die material preheated is laser cut, the laser cutting time is long due to the thickness of the die material, which leads to the problem that the die is prone to heat loss, and the change of temperature also affects the quality of laser cutting. SUMMARY

Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0039] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0040] Example: A laser cutting device for stamping die production, see attached document. Figure 1 -Appendix Figure 5 The system includes a flat plate 1, a support plate 26, a transfer mechanism 3, a heating ring, and a laser cutting head. The flat plate 1 is a circular plate with a vertical axis. Multiple circular tubes 2 are vertically inserted through the flat plate 1, with their axes vertically aligned. These tubes 2 are evenly arranged around the axis of the flat plate 1 and are respectively configured as a loading tube 21, a first preheating tube 22, a second preheating tube 23, and a cutting tube 24 in a clockwise or counterclockwise direction. Each of the loading tube 21, the first preheating tube 22, the second preheating tube 23, and the cutting tube 24 contains a support plate 26. Plate 26 is used to support the mold material; the transfer mechanism 3 is used to drive the mold material to move sequentially within the filling tube 21, the first preheating tube 22, the second preheating tube 23, the cutting tube 24, and the filling tube 21; an annular groove is provided on the inner wall of the cutting tube 24, the heating ring is embedded in the annular groove and fixedly connected to the cutting tube 24, and the height of the heating ring is higher than the height of the support plate 26 inside the cutting tube 24; the laser cutting head is located above the cutting tube 24, and the laser cutting head moves horizontally to complete the cutting of the mold material inside the cutting tube 24.

[0041] The temperature of the second preheating tube 23 is equal to the temperature required to preheat the mold material. The temperature inside the first preheating tube 22 is lower than the temperature inside the second preheating tube 23. Both the first preheating tube 22 and the second preheating tube 23 are equipped with electric heating elements for heating the mold material. The temperature inside the cutting tube 24 is equal to the temperature inside the second preheating tube 23.

[0042] The operator loads the mold material onto the transfer mechanism 3 at the loading tube 21. The transfer mechanism 3 moves the mold material to stay in the first preheating tube 22, the second preheating tube 23 and the cutting tube 24 in sequence. The mold material reaches the preheating temperature through the preheating in the first preheating tube 22 and the second preheating tube 23. Then the mold material is cut in the cutting tube 24 by the laser cutting head above the cutting tube 24. After the cutting is completed, it is transferred to the loading tube 21 by the transfer mechanism 3. The operator takes out the mold material that has been cut in the loading tube 21 and fills it with the mold material to be cut, repeating the above steps.

[0043] Specifically, the laser cutting head above the cutting tube 24 can move in any direction in the horizontal plane to cut the mold material.

[0044] Specifically, the transfer mechanism 3 includes a rotating shaft 31 and clamping components 32. The rotating shaft 31 passes vertically through the plate 1 and is coaxial with the plate 1. The rotating shaft 31 can rotate around its own axis. A connecting component is provided outside the rotating shaft 31, and four connecting components are provided. Four clamping components 32 are provided and are respectively connected to four connecting components. The clamping components 32 are used to clamp the mold material. The mold material clamped by the four clamping components 32 is located in the filling tube 21, the first preheating tube 22, the second preheating tube 23 and the cutting tube 24 respectively, and moves sequentially in the filling tube 21, the first preheating tube 22, the second preheating tube 23 and the cutting tube 24 under the rotation of the rotating shaft 31.

[0045] The clamping assembly 32 clamps and fixes the mold material, and then the rotation of the rotating shaft 31 drives the clamping assembly 32 to move sequentially in the filling tube 21, the first preheating tube 22, the second preheating tube 23 and the cutting tube 24.

[0046] Specifically, the transfer mechanism 3 also includes a lifting plate 34, which is located below the flat plate 1. Multiple cylinders are fixedly connected to the bottom of the flat plate 1. The cylinder body is fixedly connected to the flat plate 1, and the piston rod of the cylinder is fixedly connected to the lifting plate 34. One end of the bottom of the rotating shaft 31 is rotatably connected to the lifting plate 34. A motor that drives the rotating shaft 31 to rotate is fixedly connected to the bottom of the lifting plate 34.

[0047] Specifically, the clamping assembly 32 includes a collar 321, clamping rods 322, an elastic element 323, a support plate 324, and a clamping plate 325. The collar 321 has a vertical axis and its inner diameter is larger than the diameter of the cutting tube 24. When the collar 321 rotates with the rotating shaft 31 to the cutting tube 24, the collar 321 is coaxial with the cutting tube 24. Four clamping rods 322 are provided and arranged around the axis of the collar 321. The length direction of the clamping rods 322 is along the radial direction of the collar 321. The clamping rod 322 is oriented so that it passes through the collar 321 along its own length and can slide on the collar 321 along its own length. Each clamping rod 322 corresponds to an elastic element 323. A horizontally arranged support plate 324 is fixedly connected to one end of each clamping rod 322 near the axis of the collar 321. The clamping plate 325 is fixedly connected to the top of the support plate 324. The elastic element 323 applies elastic force to the clamping rod 322 to push the clamping rod 322 to clamp the clamping plate 325 on the outside of the mold material.

[0048] The connecting assembly outside the rotating shaft 31 includes two crossbars 33, with the two ends of the crossbars 33 fixedly connected to the rotating shaft 31 and the collar 321, respectively.

[0049] Specifically, a clearance groove 3241 is provided at one end of the support plate 324 near the axis of the collar 321, which is vertically penetrating the support plate 324. Support rods 3242 are provided on both sides of the clearance groove 3241. Four grooves 25 are provided around the circular tube 2, which penetrate the circular tube 2 in the radial direction. The grooves 25 penetrate the circular tube 2 vertically upward. The four clamping rods 322 of the clamping assembly 32 can be inserted into the four grooves 25 from top to bottom respectively.

[0050] When the clamping assembly 32 moves to the top of any circular tube 2 under the action of the rotating shaft 31, the four clamping rods 322 of the clamping assembly 32 correspond to the four grooves 25 on the circular tube 2 respectively. Then the lifting plate 34 moves downward, thereby driving the four clamping rods 322 to be inserted into the four grooves 25 respectively, thus realizing the placement of the mold material in the circular tube 2. When the mold material is removed from the circular tube 2, the lifting plate 34 moves upward, driving the clamping rods 322 to move upward and disengage from the grooves 25, thereby driving the mold material to move upward and disengage from the circular tube 2. Then, through the rotation of the rotating shaft 31, the mold material can be moved between different circular tubes 2.

[0051] Specifically, the top of the support plate 26 is provided with several vertically arranged support rods 261, and gaps are provided between adjacent support rods 261; two guide blocks 251 are fixedly connected to the outside of the round tube 2 on both sides of the groove 25, and the side of the guide block 251 away from the round tube 2 is set as an inclined surface, and the end of the inclined surface near the top is inclined towards the direction close to the round tube 2; a guide rod 3221 with a horizontal length direction and perpendicular to the clamping rod 322 is fixedly connected to the clamping rod 322. When the clamping rod 322 is inserted into the groove 25, the guide rod 3221 contacts the inclined surface on the guide block 251 to drive the guide rod 3221 to slide, thereby driving the support rod 3242 to detach from the bottom of the mold material.

[0052] The support rod 261 prevents the laser cutting head from damaging the support plate 26 when cutting the mold material. As the clamping assembly 32 moves downward from above the circular tube 2, the clamping rod 322 is inserted downward into the groove 25. Under the action of the guide rod 3221 and the inclined surface, the support rod 3242 moves away from the axis of the circular tube 2 at the bottom of the mold material. When the clamping rod 322 is inserted to the bottom of the groove 25, the height of the support rod 3242 is lower than the height of the bottom of the mold material and the support rod 3242 is disengaged from the bottom of the mold material. When the clamping assembly 32 moves upward from the circular tube 2, the clamping rod 322 moves upward in the groove 25. Under the elastic action of the elastic element 323, the support rod 3242 at the bottom of the mold material slides towards the axis of the circular tube 2. When the top height of the support rod 3242 is level with the bottom height of the mold material, the support rod 3242 contacts the bottom of the mold material. As the clamping rod 322 continues to move upward, the support rod 3242 continues to slide towards the axis of the circular tube 2 until the clamping plate 325 clamps the outside of the mold material.

[0053] Specifically, an arc-shaped baffle plate 326 is fixedly connected to the top of the support plate 324. When the clamping rod 322 moves to the bottom of the groove 25, the baffle plate 326 fits against the inner side of the round tube 2 to cover the groove 25. The clamping plate 325 is detachably connected to the two support rods 3242. Two fixing sleeves 3251 are fixedly connected to the bottom of the clamping plate 325. The two fixing sleeves 3251 are respectively sleeved on the two support rods 3242 along the length direction of the support rods 3242. Bolts are provided on the fixing sleeves 3251 to fix the fixing sleeves 3251 to the support rods 3242.

[0054] By setting up the baffle plate 326, the heat loss from the first preheating pipe 22, the second preheating pipe 23, and the cutting pipe 24 can be reduced.

[0055] Specifically, the elastic element 323 is configured as a spring and sleeved outside the clamping rod 322. One end of the elastic element 323 is fixedly connected to the outside of the collar 321, and the other end is fixedly connected to the end of the clamping rod 322 away from the support plate 324.

[0056] Specifically, the support plate 26 inside the cutting tube 24 is set as a flip support plate 26, and several support rods 261 are fixedly connected to the top and bottom of the flip support plate 26; a rotating rod 262 is fixedly connected to the flip plate along the radial direction of the flip plate, the rotating rod 262 is rotatably connected to the cutting tube 24, and the end of the rotating rod 262 near the rotating shaft 31 extends through the cutting tube 24 toward the rotating shaft 31; a bevel gear 5 is fixedly connected to the outside of the rotating shaft 31 and the end of the rotating rod 262 near the rotating shaft 31. When the lifting plate 34 moves upward and drives the clamping assembly 32 to disengage from the round tube 2, the bevel gear 5 on the rotating shaft 31 meshes with the bevel gear 5 outside the rotating rod 262. For every quarter turn of the rotating shaft 31, the rotating rod 262 rotates half a turn.

[0057] After the mold material is cut inside the cutting tube 24, waste material will remain on the support rod 261 at the top of the support plate 26. By setting the support plate 26 inside the cutting tube 24 as a flip support plate 26, and during the process of transferring the mold material by rotating the shaft 31 by a quarter turn, the bevel gear 5 drives the flip support plate 26 to rotate half a turn, or 180 degrees, to achieve the interchange of the top and bottom of the support plate 26. This allows the waste material on the support rod 261 to fall off the support rod 261 during the flipping process of the support plate 26.

[0058] Specifically, a cover plate 4 is provided on the top of the first preheating pipe 22 and the second preheating pipe 23. The cover plate 4 can move up and down to open and close the first preheating pipe 22 and the second preheating pipe 23.

[0059] Specifically, a vertically arranged lifting rod 41 is fixedly connected to the cover plate 4. The lifting rod 41 is fitted with a guide sleeve 42 fixedly connected to the outside of the circular plate. The lifting rod 41 slides up and down in the guide sleeve 42 to drive the cover plate 4 to slide up and down. A connecting plate 43 is fixedly connected to the bottom of the two lifting rods 41. The connecting plate 43 is fixedly connected to the lifting plate 34 through the connecting rod 44. When the lifting plate 34 moves upward and drives the clamping assembly 32 to disengage from the circular tube 2, the lifting plate 34 simultaneously drives the cover plate 4 to move upward so that the cover plate 4 will not obstruct the clamping assembly 32 from disengaging from the first preheating tube 22 and the second preheating tube 23.

[0060] Specifically, the bottom of the plate 1 is fixedly connected with multiple vertical rods 11 for supporting the plate 1.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
