Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, a mold for rotary cutting a product is provided, which includes an upper mold and a lower mold, wherein the upper mold is disposed at an upper portion of the lower mold. The upper die comprises an upper die base 1, an upper die plate 2 and a cylinder, wherein the upper die plate 2 is arranged at the lower part of the upper die base 1 and connected with the upper die base 1. And a product placing cavity 3 is arranged at the position of the upper template 2 corresponding to the positioning column 9. The cylinder is connected with the upper die and drives the upper die to move up and down.

The lower die comprises a rotary cutting knife 4, a knife connecting plate 5, a rotary fixing plate 6, a movable connecting piece, a rotary cutting guide block 7, a rotary cutting track 8, a positioning column 9, a positioning plate 10, a lower die holder 11 and a lower die plate 12. The cutter connecting plate 5 is arranged between the rotary cutter 4 and the rotary fixing plate 6 and is used for connecting the rotary cutter 4 and the rotary fixing plate 6. The edge of the cutter connecting plate 5 is smaller than the edge of the rotary fixing plate 6. The arrangement of the cutter connecting plate 5 can enable the rotary cutter 4 to be higher than the top surface of the rotary cutting guide block 7, so that the rotary cutter 4 can conveniently perform rotary cutting.

The lower template 12 is located on the lower die base 11 and is connected with the lower die base 11. The movable connecting piece is positioned at the lower part of the rotary fixing plate 6 and is fixedly connected with the lower template 12. The movable connecting piece is a spring. The rotary cutting guide blocks 7 are positioned around the rotary fixing plate 6 and fixedly connected with the lower template 12. The rotary cutting guide block 7 is arranged in a ring shape. The rotary cutting rail 8 is located on the side wall of the rotary cutting guide block 7, that is, a groove is provided on the side wall of the rotary cutting guide block 7, and the rotary cutting rail 8 is also a groove.

The rotary cutting track 8 is arranged in an annular shape, the central axis of the rotary cutting track 8 and the horizontal plane form a certain angle, and the design of the angle is set according to the shape of a product. The edge of the rotary fixing plate 6 is inserted into the rotary cutting rail 8. When the rotary fixing plate 6 is subjected to a downward force, the rotary fixing plate 6 rotates in the rotary cutting track 8. The center positions of the cutter connecting plate 5 and the rotary fixing plate 6 are provided with holes, and the positioning column 9 penetrates through the cutter connecting plate 5 and the rotary fixing plate 6. The positioning columns 9 are inserted into the lower template 12 and fixed. The positioning plate 10 is arranged on the upper portion of the positioning column 9, a product can be placed on the upper portion of the positioning column 9, and the positioning plate 10 is attached to the side face of the product.

The rotary cutting machine comprises a rotary cutting knife 4, a knife connecting plate 5, a rotary fixing plate 6, a movable connecting piece, a rotary cutting guide block 7, a rotary cutting track 8, a positioning column 9, a positioning plate 10, a lower die holder 11 and a lower die plate 12

The working process of the die for rotary cutting the product comprises the following steps: the product 13 to be rotary-cut is placed on the positioning column 9, and the positioning plate 10 can fix and position the product to be rotary-cut, so that the product 13 to be rotary-cut is stably placed on the positioning column 9. The cylinder drives the upper die to move downwards, and a product 13 needing rotary cutting enters the product placing cavity 3 of the upper die. The upper die continues to move downwards, the upper die applies force to the rotary fixing plate 6, the rotary fixing plate 6 rotates along the rotary cutting rail 8 due to the fact that the central axis of the rotary cutting rail 8 forms a certain angle with the horizontal plane, meanwhile, the movable connecting piece is twisted and compressed to reach the position shown in fig. 2, and left punching can be completed. The upper die continues to descend, the rotary fixing plate 6 continues to rotate along the rotary cutting track 8 to reach the position shown in fig. 3, and forward punching can be completed. The upper die continues to descend, the rotary fixing plate 6 continues to rotate along the rotary cutting track 8 to reach the position shown in fig. 4, and then rightward punching can be completed. The upper die continues to descend, the rotary fixing plate 6 continues to rotate along the rotary cutting track 8 to reach the position shown in fig. 5, and backward punching can be completed. Thereby the rotary fixing plate 6 drives the rotary cutter 4 to rotate 360 degrees, and the whole rotary cutting process is completed. The cylinder drives the upper die to move upwards to a die opening state. And taking down the product. Because the movable connector is twisted and compressed, when the downward force of the upper die disappears, the movable connector enables the rotary fixing plate 6 to rotate 360 degrees in the opposite direction for restoration, and the original state is restored.

The utility model has the advantages that:

the die for rotary cutting the product is ingenious in structural design, low in cost and easy to manufacture, and can be used for producing a stretched product without a flange edge;

and secondly, the die for rotary cutting the product meets the condition of high tolerance requirement of the end face of the tensile member product, and is suitable for wide application in production.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
