Description

Technical Field

[0001] This utility model relates to a rotary open-type upper mold device, belonging to the field of mold technology. Background Technology

[0002] Various types of square steel serve different functions in different parts of artillery, such as providing support and reinforcing ribs. For special applications, due to structural requirements and space constraints, standard square steel cannot be selected, necessitating the design of non-standard square steel. This type of square steel requires four pressing processes from sheet metal, with a straight weld joint left on one side before final welding. The stamping process for square steel presents challenges in mold design. To address these challenges, a rotary open structure is adopted, which is simple in structure, flexible in operation, and allows for the rapid stamping of non-standard square steel. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a rotary open forming upper die device, which can effectively realize the simple, convenient and efficient stamping of non-standard square steel.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a rotary open-type upper mold device, including an upper mold plate, an upper mold stop block, a sliding stop block, a fixed shaft, an upper mold and an upper mold connecting block. The upper mold stop block and the upper mold connecting block are respectively fixedly connected to both sides of the bottom of the upper mold plate. The upper mold connecting block is L-shaped. The end of the vertical part of the upper mold connecting block is fixedly connected to one side of the bottom of the upper mold plate, and the horizontal part of the upper mold connecting block faces the upper mold stop block.

[0005] A through hole is provided in the sliding block, and bolt I is threaded through the through hole on the sliding block and connected to the front side of the upper mold block; at a position diagonally below the through hole, a threaded hole is provided in the sliding block, and the end of bolt II is threaded into the threaded hole.

[0006] The fixed shaft is threaded to the front side of the upper die stop, and the fixed shaft is adjacent to the sliding stop. The upper die stop is a rectangular block with a protruding step on one side. A bushing is installed in the horizontal part of the upper die connecting block. The bushing can rotate and slide in the inner hole of the upper die connecting block, and is bolted to the bushing. An upper die is set below the horizontal part of the upper die connecting block. One end of the upper die is fixed to the lower part of the upper die connecting block by bolts, and the other end of the upper die is attached to the step of the upper die stop. Bolt II drives the sliding stop to rotate around bolt I to the lower end to fix this end of the upper die.

[0007] Furthermore, the diameter of the through hole in the sliding stop is larger than the diameter of bolt I.

[0008] The beneficial effects of this utility model are: This utility model can complete the stamping and forming of non-standard square steel in a simple, convenient and efficient manner. Through the upper mold device structure, it can press and form various non-standard square steel models. Only one gap needs to be welded, which reduces welding deformation, lowers welding costs, and reduces the cost of purchasing non-standard square steel. Attached Figure Description

[0022] like Figure 1As shown in Figure 11, a rotary open-type molding upper mold device includes an upper template 1, an upper mold stop 2, a sliding stop 3, a fixed shaft 4, an upper mold 5, and an upper mold connecting block 9. The upper mold stop 2 and the upper mold connecting block 9 are respectively fixedly connected to the two sides of the bottom of the upper template 1. The upper mold connecting block 9 is L-shaped, and the end of the vertical part of the upper mold connecting block 9 is fixedly connected to one side of the bottom of the upper template 1. The horizontal part of the upper mold connecting block 9 faces the upper mold stop 2.

[0023] A through hole is provided in the sliding block 3. Bolt I10 is threaded through the through hole in the sliding block 3 and connected to the front side of the upper mold block 2. The diameter of the through hole in the sliding block 3 is larger than the diameter of bolt I10. At a position diagonally below the through hole, a threaded hole is provided in the sliding block 3. The end of bolt II11 is threaded into the threaded hole.

[0024] The fixed shaft 4 is threaded to the front side of the upper mold stop 2, and the fixed shaft 4 is adjacent to the sliding stop 3. The upper mold stop 2 is a rectangular block, and a protruding step is provided on one side of the rectangular block. A bushing 8 is installed in the horizontal part of the upper mold connecting block 9. The bushing 8 can rotate and slide in the inner hole of the upper mold connecting block 9. The bolt 7 is connected to the bushing 8. An upper mold 5 is provided below the horizontal part of the upper mold connecting block 9. One end of the upper mold 5 is fixed to the lower part of the upper mold connecting block 9 by the bolt 7. The other end of the upper mold 5 is attached to the step part of the upper mold stop 2. The bolt II 11 drives the sliding stop 3 to rotate around the bolt I 10 and fix this end of the upper mold 5.

[0025] During use, the protruding step below the upper mold stop 2 can limit the upper mold 5. The diameter of the through hole in the sliding stop 3 is larger than the diameter of bolt I 10, ensuring that the sliding stop 3 can rotate around bolt 10 as the axis. The upper mold 5 can rotate around the bushing 8 below the upper mold connecting block 9 through bolt 7. When in use, the square steel parts are connected to the upper mold 5, the upper mold 5 is attached to the upper mold stop 2, and the sliding stop 3 rotates to the bottom to fix the upper mold 5. At this time, the upper mold device is in a closed state, and sheet metal can be pressed. After the non-standard square steel is pressed, the sliding stop 3 is rotated and moved away through bolt II 11, the upper mold 5 is pulled out, and the formed part 6 is taken out.
