Detailed Description
The following detailed description of the present invention is provided with reference to the accompanying drawings, but it should be understood that the scope of the invention is not limited by the detailed description.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations such as "comprises" or "comprising", etc., will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
As shown in fig. 1 to 3, a bending apparatus according to an embodiment of the present invention is used for bending a product 4, and includes a first mold 1, a movable pressing member, and a second mold 3. The first mold 1 has a cavity 11 and a bending lug 17. The movable pressing assembly is disposed in the chamber 11 and moves within the chamber 11 at a limited position, and the movable pressing assembly includes a movable pressing block 2 for fixing the product 4. The second die 3 corresponds to the first die 1, and the second die 3 is provided with a product groove 31 for placing the product 4 and a bending groove 32 in bending fit with the bending lug 17.
When the first die 1 descends to the first position, the movable pressing assembly positions and fixes the product 4 in the product groove 31; when the first die 1 descends to the second position, the product 4 is bent through the matching of the bending convex block 17 and the bending groove 32.
As shown in fig. 1, a cavity 11 is disposed through a first mold 1, the first mold 1 is provided with a first stopper 12 protruding toward the inner side of the cavity 11, and two sets of first stoppers 12 are symmetrically disposed on the first stopper 12. The movable pressing block 2 is arranged in the cavity 11, and the movable pressing block 2 can protrude out of one end of the cavity 11 so that the movable pressing block 2 can press and fix the product 4 in the product groove 31. Move and press and have the setting to prevent the spacing second stopper 21 that excessively moves of first stopper 12 according to the protrusion on the briquetting 2 for second stopper 21 is spacing to moving according to briquetting 2. The other end of the first die 1 corresponding to the cavity 11 is provided with a sealing cover 13, one side of the sealing cover 13 close to the cavity 11 is provided with a first elastic limiting groove 14, and the movable pressing block 2 is provided with a second elastic groove corresponding to the first elastic groove. An elastic piece 23 is arranged between the first elastic limiting groove 14 and the second elastic groove. One end of the elastic piece 23 is abutted against the first elastic limiting groove 14, and the other end of the elastic piece 23 is abutted against the second elastic limiting groove 22, so that the movable pressing block 2 keeps a tensioning state under the elastic force of the elastic piece 23 and the abutting action of the first limiting block 12 and the second limiting block 21. The movable pressing block 2 has a pressing portion 24 which is in contact with and connected to the product groove 31. So that when the first mold 1 approaches the second mold 3, the pressing part 24 of the movable pressing block 2 first contacts the product 4 in the product groove 31 to apply pressure on the product 4, thereby fixing and positioning the product 4.
