Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a one-time rolling molding mold. Background Art

[0002] A rolling forming die is a die used to bend a metal sheet into a circle. This die is usually composed of two upper and lower dies, the upper die and the lower die are connected together by a mechanical transmission or hydraulic system. During the rolling process, the lower die is fixed, while the upper die rotates around the lower die, and the metal sheet is rolled into the die at the same time. As the rolling process proceeds, the metal sheet gradually bends into a circle. The roll made by this processing method does not connect the two ends of the metal sheet tightly enough, and a subsequent process is required to extrude the two sides of the processed roll so that the two ends of the metal sheet are connected to form a roll, which increases the operation process, and the metal sheet is easily stuck on the lower die, making it difficult to demould, affecting the continuous progress of the work and affecting the work efficiency. Therefore, a rolling one-time forming die is designed to solve the above problems. Utility Model Content

[0023] Example:

[0024] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a one-time rolling forming mold, including: a base 1, a bottom mold 2, a guide column 3, a top plate 4, a hydraulic rod 5, a first lifting plate 6, a guide rod 7, a second lifting plate 8, a sleeve spring 9, a forming roller 10 and an upper mold 11, a bottom mold 2 is fixedly arranged at the center of the upper surface of the base 1, a bottom mold groove 201 is opened at the center of the upper surface of the bottom mold 2, and a limiting rod 202 is fixedly arranged on the left and right sides of the bottom mold groove 201, guide columns 3 are fixedly arranged on both sides of the base 1, and a top plate 4 is fixedly arranged on the top of the two guide columns 3. A hydraulic rod 5 is fixedly arranged at the center of the upper surface of 4, and a first lifting plate 6 is fixedly arranged at the output end of the hydraulic rod 5. Guide rods 7 are penetrated on both sides of the upper surface of the first lifting plate 6, and a second lifting plate 8 is fixedly arranged at the bottom of the guide rod 7. A sleeve spring 9 is fixedly arranged between the first lifting plate 6 and the second lifting plate 8, and the sleeve spring 9 is sleeved on the guide rod 7. A forming roller 10 is installed at the center of the right side of the second lifting plate 8. An upper mold 11 is fixedly arranged at the center of the right side surface of the first lifting plate 6, and an upper mold groove 1101 is opened at the center of the bottom of the upper mold 11.

[0025] During actual use, the workpiece to be rolled is placed between the two limit rods 202 on the bottom mold 2, and the hydraulic rod 5 is turned on. The hydraulic rod 5 is extended to drive the first lifting plate 6 and the second lifting plate 8 to move downward. The forming roller 10 on the second lifting plate 8 contacts the workpiece, presses the workpiece into the bottom mold groove 201, and presses the workpiece into a semicircular shape. The hydraulic rod 5 moves downward again, so that the first lifting plate 6 moves downward relative to the second lifting plate 8. The sleeve spring 9 is in a compressed state, the first lifting plate 6 drives the upper mold 11 to move downward, and the upper mold groove 1101 presses the workpiece into a ring shape, achieving the effect of one-time rolling. The operation is simple and convenient, and the work efficiency is increased.

[0026] The corresponding arcs of the bottom die groove 201 and the upper die groove 1101 are both equal to 180°, so that the bottom die groove 201 cooperates with the upper die groove 1101 to press the plate-shaped workpiece into a circular ring shape.
