DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0023] Example:

[0024] like Figures 1 to 3 As shown, a cutting die for edge processing of waste materials is used for punching holes in die-casting parts, comprising: a support table 1, the support table 1 is connected to a stamping plate 2 through a plurality of guide pillars, the stamping plate 2 is fixedly connected to a lower pressure plate 3, and a buffer plate 4 is connected between the lower pressure plate 3 and the stamping plate 2 through a buffer assembly.

[0025] A cutting plate 5 is fixedly connected to the bottom of the stamping plate 2, and a plurality of cutting knives 6 are fixedly connected to the cutting plate 5. A contact plate 7 is provided directly below the cutting plate 5, and a bolt 8 is fixedly connected to the contact plate 7. The bolt 8 passes through the cutting plate 5 and the stamping plate 2 and contacts the buffer plate 4.

[0026] The buffer assembly includes: a plurality of connecting columns 9 arranged between the punching plate 2 and the lower pressing plate 3, and the connecting columns 9 are sleeved with a first spring 10 for driving the buffer plate 4 downward. When the punching plate 2 drives the buffer plate 4, the cutting plate 5, the cutting knife 6 and the abutting plate 7 downward, the abutting plate 7 first contacts with the die casting, and when the punching plate 2 continues to move downward, the abutting plate 7 drives the buffer plate 4 to compress the first spring 10 through the bolt 8, thereby achieving the buffering of the abutting plate 7.

[0027] The support table 1 is fixedly connected to a reset component that drives the stamping plate 2 upward, and the reset component includes: a positioning block 11 fixedly set on the support table 1, the positioning block 11 is matched with a telescopic rod, and the end of the telescopic rod is fixedly connected to a first wedge block 12, a second spring is provided between the first wedge block 12 and the positioning block 11, and a second wedge block 13 matched with the first wedge block 12 is fixedly connected to the lower surface of the stamping plate 2.

[0028] When the stamping plate 2 moves downward, the second wedge block 13 will be driven to cooperate with the first wedge block 12, driving the first wedge block 12 to compress the second spring. When the stamping plate 2 loses the downward driving force, the second spring will drive the first wedge block 12 to cooperate with the second wedge block 13, and drive the stamping plate 2 upward.

[0029] The support platform 1 is equipped with a material lifting assembly, which drives the waste materials after punching to move upward.

[0030] The material lifting assembly includes: a lifting plate 14, a plurality of buffer columns 15 are fixedly connected to the lower surface of the lifting plate 14, the buffer columns 15 extend to the lower surface of the support platform 1, a buffer spring 16 is arranged between the lifting plate 14 and the support platform 1, and a groove adapted to the waste is arranged on the upper surface of the lifting plate 14. A plurality of abutment columns 18 are fixedly connected to the lower surface of the cutting plate 5.

[0031] When the punching plate 2 moves downward, it drives the cutting knife 6 and the abutting column 18 downward. The cutting knife 6 cuts the inner side. The abutting column 18 drives the inner waste downward and cooperates with the lifting plate 14. The lifting plate 14 moves downward and compresses the buffer spring 16.

[0032] When the punching plate 2 moves upward, the buffer spring 16 drives the lifting plate 14 upward and drives the waste to be lifted, thereby reducing the phenomenon of waste being stuck in the edge cutting die, simplifying the process flow, and improving production efficiency and reducing labor costs.

[0033] When the punch is moving downward, in order to avoid damage to the die casting due to excessive punching, the support platform 1 is fixedly connected with a plurality of limit columns 19 , which limit the downward distance of the punch plate 2 .

[0034] The stamping plate 2 is matched with a guide sleeve 20, and the outer wall of the guide sleeve 20 is provided with an arc groove. The stamping plate 2 is matched with a plurality of L-shaped blocks 21 through screws. The screws drive the L-shaped blocks 21 to match with the arc grooves, and drive the guide sleeve 20 to be fixedly set on the stamping plate 2. The guide sleeve 20 is mainly matched with the guide column. There is friction between the guide column and the guide sleeve 20. In order to facilitate subsequent replacement, the guide sleeve 20 can be quickly replaced mainly by matching the L-shaped blocks 21 with the arc grooves, and the difficulty of replacement can be reduced.

[0035] The support platform 1 is provided with a material drop opening 17, which extends to the lower surface of the support platform 1. A plurality of support plates 22 are fixedly connected to the lower surface of the support platform 1, and the plurality of support plates 22 drive the lower surface of the support platform 1 to form a storage space. When the waste on the inner parting line is separated from the die casting, it can fall into the storage space through the material drop opening 17, and a storage drawer can be provided in the storage space to facilitate the collection of the waste.

[0036] like Figures 1 to 3As shown, during operation, when the stamping plate 2 drives the buffer plate 4, the cutting plate 5, the cutting knife 6 and the abutment plate 7 downward under the action of external force, the abutment plate 7 first contacts the die-casting. When the stamping plate 2 continues to move downward, the abutment plate 7 drives the buffer plate 4 through the bolt 8 to compress the first spring 10, thereby achieving buffering of the abutment plate 7.

[0037] When the stamping plate 2 moves downward, it drives the cutting knife 6 and the abutment column 18 downward. The cutting knife 6 cuts the scrap corners on the inner and outer parting lines. The abutment column 18 drives the inner scrap downward and cooperates with the lifting plate 14. The lifting plate 14 moves downward and compresses the buffer spring 16.

[0038] When the punching plate 2 moves upward, the buffer spring 16 drives the lifting plate 14 upward and drives the waste to be lifted, thereby reducing the phenomenon of waste being stuck in the edge cutting die, simplifying the process flow, and improving production efficiency and reducing labor costs.

[0039] When the stamping plate 2 moves downward, the second wedge block 13 will be driven to cooperate with the first wedge block 12, driving the first wedge block 12 to compress the second spring. When the stamping plate 2 loses its downward force, the second spring will drive the first wedge block 12 to cooperate with the second wedge block 13, and drive the stamping plate 2 upward.

[0040] Therefore, various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
