[0013] Figure 1 This is a schematic diagram of the three-way ring forging top circle device described in this utility model. Detailed Implementation
[0014] The utility model will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0015] like Figure 1As shown, the three-way ring forging top circle device includes: a circular base 1 for placing a triangular ring forging 5 and three hydraulic cylinders 2. Abutment 3 is coaxially arranged at the center of the circular base 1. The three hydraulic cylinders 2 are arranged at 120-degree angles to each other around the abutment 3, with the tail ends of the three hydraulic cylinders abutting against the abutment 3. Each of the three hydraulic cylinders 2 has a top block 4 at the top of its piston rod. After the piston rods of the three hydraulic cylinders 2 extend, the top blocks 4 can respectively abut against the inner ring of the triangular ring forging 5 placed on the circular base 1. By adjusting the extension and retraction of the piston rods of the three hydraulic cylinders 2, the triangular ring forging 5 can be... The ring forging 5 has a top circle. A vertically arranged upright 6 is set at the center of the boss 3. A telescopic crossbar 7 is set next to the upright 6. The inner end of the crossbar 7 is hinged to the top of the upright 6, so that the crossbar 7 can rotate around the upright 6. A vertically arranged telescopic compass 8 is set next to the crossbar 7. The tail end of the telescopic compass 8 is fixed to the outer end of the crossbar 7. After the telescopic compass 8 rotates around the upright 6 via the crossbar 7, it can draw a circle on the upper surface of the triangular ring forging 5. Whether the ring forging is top circled can be confirmed by comparing it with the drawn circle.
[0016] In this embodiment, the abutment 3 is an equilateral triangular prism, and the tail ends of the three hydraulic cylinders 2 abut against the three side walls of the abutment 3 one-to-one.
[0017] A triangular positioning groove 9 is provided at the center of the circular base 1, and the abutment boss 3 can be positioned on the circular base 1 by inserting it into the triangular positioning groove 9. This design makes it easy to disassemble the abutment boss 3, thus facilitating storage.
[0018] Circular positioning grooves 10 are provided on the three side walls abutting the boss 3. The tail ends of the three hydraulic cylinders 2 are respectively inserted into one of the circular positioning grooves 10 for positioning. A retaining groove 11 is provided at the top of each of the three circular positioning grooves 10. Positioning studs 12 are threadedly connected to the top of the tail ends of the three hydraulic cylinders 2. When the tail ends of the three hydraulic cylinders 2 are inserted into the circular positioning grooves 10, they can be engaged in the retaining grooves 11 by the positioning studs 12 for circumferential positioning. This arrangement facilitates accurate positioning and installation of the three hydraulic cylinders 2.
[0019] Three pads 13 are also provided. The upper surface of each pad 13 is an arc-shaped surface that can fit against the side wall of the cylinder body of the hydraulic cylinder 2. One pad 13 is placed under each hydraulic cylinder 2. This arrangement makes the top circle of the hydraulic cylinder 2 more stable.
[0020] The top block 4 is threaded to the top of the piston rod of the hydraulic cylinder 2, and the end face of the top block 4 that contacts the inner ring of the triangular ring forging 5 is arc-shaped. This design facilitates the replacement of the top block 4. In addition, setting the end face of the top block 4 to be arc-shaped helps to make the top of the ring forging rounder and makes it less likely to scratch the ring forging.
[0021] The device also includes a first extension ring 14 and a second extension ring 15. An outer step is provided on the outer edge of the circular base 1. An inner step is provided on the inner ring of the first extension ring 14 to cooperate with and position it against the outer step. The first extension ring 14 can be fitted onto the outer side of the circular base 1 through the cooperation of the inner and outer steps. After the first extension ring 14 is fitted, its upper end face is flush with the upper end face of the circular base 1. The first extension ring 14 can also be used to support the triangular ring forging 5. Similarly, an outer step is provided on the outer edge of the first extension ring 14, and an inner step is provided on the inner ring of the second extension ring 15 to cooperate with and position it against the outer step. The second extension ring 15 can be fitted onto the outer side of the first extension ring 14 through the cooperation of the inner and outer steps. After the second extension ring 15 is fitted, its upper end face is flush with the upper end face of the first extension ring 14. The second extension ring 15 can also be used to support the triangular ring forging. With this configuration, when the inner diameter of the ring forging is larger than the outer diameter of the circular base 1, the support range of the circular base 1 can be expanded by installing the first extension ring 14 and the second extension ring 15.
