Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an adjustable positioning tooling for a die forging hydraulic press. Background Technology

[0002] Valve body forgings are widely used in key sectors of the national economy such as petroleum and nuclear power. During operation, the valve body is subjected to high pressure. In order to meet the increasingly demanding requirements, the use of die forging or extrusion to form valve bodies has become the current trend. Positioning fixtures are required during the die forging process of valve bodies.

[0003] The currently published patent, CN220515337U, discloses a valve body forging positioning fixture. After the valve blank is placed inside two steel strips, the drive motor can be started to drive the screw to rotate. At this time, under the thread transmission with the threaded plate, the slide can be moved forward. Then, the connecting rod can be moved forward through the support rod and the fixed rod. When the connecting rod moves, the two steel strips can be contracted through the two connecting pieces, so as to achieve stable clamping of the valve blank and achieve stable braking of the valve blank.

[0004] Based on the above search results, when this forging positioning fixture is in use, the two connecting plates can drive the two steel strips to retract, thereby achieving stable clamping of the valve blank and stable braking of the valve blank. The two steel strips clamp and fix the blank. However, after the two steel strips have fixed the blank, they cannot be adjusted to move the blank to adjust its position. Since the blank needs to be moved to forge different parts during forging, this affects the convenience of the operator to move the blank and reduces the forging efficiency of the blank. Utility Model Content

This tooling can solve the problem that after the two steel strips are fixed to the billet, it is impossible to adjust the position of the two steel strips and move the billet to adjust its position. Since the billet needs to be moved to forge different parts during forging, this affects the convenience of the operator to move the billet and reduces the forging efficiency of the billet.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable positioning die forging hydraulic press fixture, including a fixture frame and a forging workpiece moving device; the forging workpiece moving device includes a forging slide, two guide sliders, a connecting bridge plate and a hydraulic press, the forging slide is slidably installed on the top of the fixture frame, two guide grooves are opened on the top of the fixture frame, the two guide sliders are slidably connected inside the two guide grooves respectively, the two guide sliders are fixedly connected to the bottom of the forging slide, the connecting bridge plate is fixedly connected to the bottom of the two guide sliders, the connecting bridge plate is slidably installed inside the fixture frame, the hydraulic press is fixedly installed inside the fixture frame, the output end of the hydraulic press is fixedly installed on the left side of the connecting bridge plate, and two positioning clamps are slidably connected to the top of the forging slide.

[0025] Please see Figure 1-4 This utility model provides a technical solution: an adjustable positioning die forging hydraulic press fixture, including a fixture frame 1 and a forging workpiece moving device. The forging workpiece moving device includes a forging slide 2, two guide sliders 4, a connecting bridge plate 5, and a hydraulic press 6. The forging slide 2 is slidably mounted on the top of the fixture frame 1. Two guide grooves 3 are opened on the top of the fixture frame 1. The two guide sliders 4 are slidably connected inside the two guide grooves 3 respectively. The two guide sliders 4 are fixedly connected to the bottom of the forging slide 2 respectively. The connecting bridge plate 5 is fixedly connected to the bottom of the two guide sliders 4 and is slidably mounted inside the fixture frame 1. The hydraulic press 6 is fixedly mounted inside the fixture frame 1. The output end of the hydraulic press 6 is fixedly mounted on the left side of the connecting bridge plate 5. The top of the forging slide 2 is slidably connected to... There are two positioning clamps 7. Two mounting blocks 8 are fixedly connected to the right end of the forging slide 2. A drive motor 9 is fixedly installed inside the rear mounting block 8. Two movable plates 11 are slidably installed on the right end of the forging slide 2. The two movable plates 11 are fixedly connected to the right end of the two positioning clamps 7 respectively. The two movable plates 11 are threaded with a double-threaded rod 10 inside. The front and rear ends of the double-threaded rod 10 are threaded in opposite directions. The rear end of the double-threaded rod 10 is fixedly connected to the output end of the drive motor 9. Two protrusions 12 are fixedly connected to the left side of the forging slide 2. A guide slide rod 13 is fixedly connected inside the two protrusions 12. Two positioning sliders 14 are slidably sleeved on the surface of the guide slide rod 13. The two positioning sliders 14 are fixedly connected to the left end of the two positioning clamps 7 respectively.

[0026] After the worker places the billet inside the two positioning clamps 7, they start the drive motor 9. The output of the drive motor 9 rotates, which in turn rotates the bidirectional threaded rod 10. The rotation of the bidirectional threaded rod 10 causes the two movable plates 11 to slide relative to each other. The relative sliding of the two movable plates 11 causes the two positioning clamps 7 to slide relative to each other, clamping the billet at both ends. Thus, the billet is clamped and fixed by the two positioning clamps 7. The relative sliding of the two positioning clamps 7 also causes the two positioning sliders 14 to slide relative to each other on the surface of the guide slide rod 13. The guide slide rod 13 guides and positions the two positioning sliders 14 and the two positioning clamps 7, ensuring that the two positioning clamps 7 slide horizontally back and forth and ensuring the stability of the billet clamped by the two positioning clamps 7. Then, the worker can proceed with the process. The billet has been forged, and its bottom is supported by the forging slide 2 to ensure the stability of the forging process. When the operator needs to adjust the forging position of the billet, the operator can start the hydraulic press 6. The output end of the hydraulic press 6 can slide left and right, which will drive the connecting bridge plate 5 to slide left and right. The sliding of the connecting bridge plate 5 will drive the two guide sliders 4 and the top forging slide 2 to slide. The sliding of the forging slide 2 will drive the billet at the top to slide left and right to adjust the forging position. After the two positioning clamps 7 have fixed the billet, the operator can start the hydraulic press 6 to move the billet to adjust its position, which will facilitate the forging machine to forge different parts of the billet. Therefore, it improves the convenience of the operator to move the billet and increases the forging efficiency of the billet.

[0027] The positioning slider 14 has an annular groove 15 inside, and wear-resistant balls 16 are slidably connected inside the annular groove 15. The wear-resistant balls 16 are distributed in a circular and equidistant manner inside the annular groove 15. The wear-resistant balls 16 are in contact with the surface of the guide slide rod 13. The two positioning sliders 14 have the same structure inside.

[0028] When the positioning slider 14 slides left and right on the surface of the guide slide rod 13, the positioning slider 14 slides and drives the wear-resistant ball 16 to roll on the surface of the guide slide rod 13 through the annular groove 15. The rolling of the wear-resistant ball 16 on the surface of the guide slide rod 13 causes the positioning slider 14 to slide left and right, thereby reducing the resistance of the positioning slider 14 to slide left and right, improving the smoothness of the positioning slider 14 sliding on the surface of the guide slide rod 13, preventing the positioning slider 14 from getting stuck on the surface of the guide slide rod 13, and ensuring the stability of the two positioning sliders 14 sliding on the surface of the guide slide rod 13.
