[0002] Stamping dies are a special type of machining equipment. Stamping dies are used to process materials into parts during cold stamping. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation and plastic deformation, thereby obtaining the required parts.

[0003] During the manufacturing process of stamping dies, laser cutting is used. During the processing and forming, since the template of the stamping die is usually relatively thick, when laser cutting is used, in order to reduce the heat affected area and avoid cutting deformation and ensure the stability of cutting, the extrusion die to be cut is generally preheated.

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 and then drive the support rod (3242) to detach from the bottom of the mold material.

7. The laser cutting equipment for stamping die production according to claim 6, characterized in that: The top of the support plate (324) is fixedly connected with an arc-shaped shielding plate (326), and when the clamping rod (322) moves to the bottom of the groove (25), the shielding plate (326) fits on the inner side of the circular tube (2) to shield 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); and bolts are provided on the fixing sleeves (3251) for fixing the fixing sleeves (3251) on the support rods (3242).

8. The laser cutting equipment for stamping die production according to claim 7, characterized in that: The support plate (26) in the cutting tube (24) is configured as a flip support plate (26), and a plurality of support rods (261) are fixedly connected to the top and bottom of the flip support plate (26); A rotating rod (262) arranged along the radial direction of the rotating plate is fixedly connected to the turning plate, the rotating rod (262) is rotatably connected to the cutting tube (24), and one end of the rotating rod (262) close to the rotating shaft (31) passes through the cutting tube (24) and extends toward the rotating shaft (31); A bevel gear (5) is fixedly connected to the outer side of the rotating shaft (31) and to one end of the rotating rod (262) close to the rotating shaft (31). When the lifting plate (34) moves upward and drives the clamping assembly (32) to be separated 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). When the rotating shaft (31) rotates a quarter of a turn, the rotating rod (262) rotates half a turn.

9. The laser cutting equipment for stamping die production according to claim 8, characterized in that: A cover plate (4) is provided on the top of the first preheating tube (22) and the second preheating tube (23), and the cover plate (4) moves up and down to realize the opening and closing of the first preheating tube (22) and the second preheating tube (23).

10. The laser cutting equipment for stamping die production according to claim 9, characterized in that: A vertically arranged lifting rod (41) is fixedly connected to the cover plate (4), and a guide sleeve (42) fixedly connected to the outer side of the circular plate is provided on the outer cover of the lifting rod (41). 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), and the connecting plate (43) is fixedly connected to the lifting plate (34) through a connecting rod (44). When the lifting plate (34) moves upward and drives the clamping assembly (32) to separate upward from the round tube (2), the lifting plate (34) simultaneously drives the cover plate (4) to move upward so that the cover plate (4) will not block the clamping assembly (32) from separating from the first preheating tube (22) and the second preheating tube (23).
