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] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] See also Figure 1-4 The utility model provides a cutting device for producing blanks with pliers, comprising an operating platform 1, a material receiving frame 2 is fixedly connected to one side of the operating platform 1, a first U-shaped door 4 and a second U-shaped door 9 are fixedly connected to the top of the operating platform 1, and an inclined surface is provided on the outer surface of one side of the material receiving frame 2 of the operating platform 1, a first electric cylinder 5 is fixedly connected to the bottom of the first U-shaped door 4, a cutting assembly 6 is fixedly connected to the bottom of the first electric cylinder 5, a cutting knife 7 is provided at the bottom of the cutting assembly 6, a groove is provided on the top of the operating platform 1, and a rotating block 3 for shifting materials is rotatably provided on one side of the groove of the operating platform 1, The interior of the groove is provided with a clamping mechanism that can be raised and lowered and is used to clamp the blank. When the blank needs to be processed, it can be placed in the interior of the groove from one side of the cutting knife 7, and the blank can be positioned and clamped by the clamping mechanism, so that the blank is clamped directly below the cutting knife 7, so that the first electric cylinder 5 can be extended and retracted to use the cutting knife 7 to cut the blank. After the cutting is completed, the clamping mechanism is lifted as a whole, and the rotating block 3 is rotated to move the blank to the inclined surface, and it slides through the inclined surface to the inside of the material receiving frame 2 for collection, thereby avoiding manual material picking and placing, and the material picking position overlaps with the cutting knife 7, thereby causing safety hazards.

[0024] It should be noted that in order to cool down during cutting, there is a position on the top of the operating platform 1 for installing a water flushing device, and the operating platform 1 can also be used to drill drainage holes. However, because it is not a problem that needs to be solved by this solution and it is a prior art, it is not mentioned in the article and it is not impossible to set it up.

[0025] The rotation of the rotating block 3 mentioned above can be achieved by opening the first motor 8 on the top of the supporting block 17 in the notch on the first U-shaped door 4, and using the rotation of the rotating shaft to drive the rotating block 3 to rotate, thereby realizing the rotating material shifting work of the rotating block 3.

[0026] Furthermore, in order to clamp and position the blank, the third motor 12 on one side of the lifting block 11 is turned on, and the bidirectional threaded rod 13 rotating inside the slide groove is used to drive the two clamping plates 16 to move toward each other under the condition that the two connecting blocks 14 are slidably set inside the slide groove, so as to clamp the blank. When the second electric cylinder 10 at the bottom of the second U-shaped door 9 contracts, the sliding plate 15, the two clamping plates 16, the three connecting blocks 14 and the lifting block 11 are all lifted, leaving the cut blank inside the groove, providing space for the rotating block 3 to rotate and select the material.

[0027] Furthermore, in order to ensure the stability of the sliding plate 15 when sliding on the two clamping plates 16, and the stability of the two clamping plates 16 themselves when sliding, a connecting block 14 is fixed to the bottom of the sliding plate 15 and the two clamping plates 16, and the three connecting blocks 14 are all slidably arranged inside the sliding groove.

[0028] In order to avoid being affected when the rotating block 3 rotates, the size of the rotating block 3 matches the size of the opening, and arc surfaces are provided at both ends of the rotating block 3. In order to ensure the stability of the lifting block 11 during lifting, the two sides of the lifting block 11 are respectively fitted with the two sides of the inner cavity of the operating platform 1, and the lifting block 11 is located directly above the inclined surface.

[0029] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0030] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0031] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
