Description

Technical Field

[0001] This utility model relates to the field of clamp technology, and in particular to a multi-specification bending device for clamps. Background Technology

[0002] The clamp tape is a key component of the clamping system. Its main function is to apply circumferential pressure directly to the connected components such as pipes and hoses through tightening via bolts, nuts, or other adjusting mechanisms, achieving a tight fixation. This mechanical fastening prevents loosening or displacement of the connection due to vibration or external forces. When tightened, the clamp tape compresses the sealing gasket (such as a rubber ring), causing it to adhere to the pipe surface and enhancing the sealing effect. Especially under medium pressure, the continuous pressure provided by the clamp tape maintains the compression deformation of the sealing ring, thereby improving sealing reliability.

[0003] In related technologies, to ensure the forming dimensions of the clamping tape, sheet metal bending is mainly used to form the tape. This ensures that the tape maintains the correct position during operation, ensuring that the tape compresses the sealing gasket (such as a rubber ring) when tightened, promoting its contact with the pipe surface and enhancing the sealing effect. Therefore, the dimensional accuracy of the clamping tape directly affects the performance and sealing of the clamp.

[0004] However, the bending and shaping of cassettes has always been done manually using simple tools. This method makes it difficult to guarantee the dimensions of the cassettes produced, with a pass rate of only 15%. With the increasing demand for clamps, the upgrading of product types, and the continuous improvement of product quality, there is a growing demand for high-quality and high-efficiency production of cassettes in clamps. Utility Model Content The purpose of this utility model is to provide a multi-specification bending device for cassette tapes in order to solve the technical problems in related technologies.

[0005] Technical solution: A multi-specification bending device for cassette tape includes a base and a rotating shaft. The upper surface of the base has a through-hole elongated groove. There are two rotating shafts and two handle mounting plates. The two handle mounting plates are respectively mounted on the two rotating shafts. The lower ends of both rotating shafts pass through the elongated groove and are connected one end to one of two positioning plates located in a rectangular horizontal groove at the bottom of the base. The other ends of the two positioning plates are connected to the end face of the base via fixed bent pins. Handles are mounted on the sides of both handle mounting plates. A left bending plate and a right bending plate are correspondingly provided on the two handle mounting plates. A gap is provided between the left and right bending plates and the upper shaft segment of the corresponding rotating shaft for the cassette tape to pass through. The base has a slide rail groove parallel to the elongated groove, located outside the elongated groove. A stop block is slidably disposed in the slide rail groove.

[0006] Furthermore, the base has two rows of evenly distributed circular holes near the slide rail groove. The circular holes are connected to the slide rail groove, and stop pins are installed in the circular holes to limit the stop.

[0007] Furthermore, the base has two rows of evenly distributed semi-circular vertical grooves near the slide rail groove end, which cooperate with the fixing pin to fix the positioning plate. Furthermore, the lower ends of both shafts pass through elongated oval slots and are connected one-to-one with one end of two positioning plates located in the rectangular horizontal slot at the bottom of the base, and are fixed with nuts.

[0008] Furthermore, the left curved plate is provided with round holes and countersunk holes for installing pins and screws to fix the left curved plate to the corresponding handle mounting plate.

[0009] Furthermore, the right-hand bend plate is provided with round holes and countersunk holes for installing pins and screws to fix the right-hand bend plate to the corresponding handle mounting plate.

[0010] Furthermore, the handle mounting plate is provided with threaded holes, which are connected to the external threads of the handle.

[0011] Beneficial effects This utility model discloses a multi-specification bending device for cassette tapes, which is used for bending and forming cassette tapes. Compared with the traditional manual bending process using simple tools, this forming equipment has the characteristics of convenient operation, high pass rate, high production efficiency, and strong stability. Especially for mass production, this device is the most effective and has the most considerable economic benefits. Attached Figure Description
