Description

Technical Field

[0001] This utility model relates to the field of valve and pipeline castings and forgings, and in particular to a high-efficiency valve and pipeline mold steel casting and forging. Background Technology

[0002] In modern industrial production, valves and pipelines, as key components of fluid transport systems, are widely used in numerous fields such as petroleum, chemical, water conservancy, and energy. Their quality and performance directly affect the safe and stable operation of the entire system, and the production of valves and pipelines is inseparable from the precision machining of mold steel castings and forgings. With the continuous improvement of industrial automation, increasingly higher demands are being placed on the production efficiency and adaptability of valve and pipeline mold steel castings and forgings. Highly efficient, stable processing equipment that can adapt to multi-specification production has become an urgent need for industry development.

[0003] Currently, existing equipment has several shortcomings in the stamping process of valve and pipe die steel castings and forgings. In the part removal stage, manual removal is still the primary method. However, stamped workpieces are often difficult to demold quickly due to their tight fit with the die, requiring workers to spend considerable time and effort on separation. This not only increases labor intensity but also slows down the overall production pace due to the slow demolding process, severely hindering production efficiency. Furthermore, some auxiliary demolding structures lack effective limiting guidance, making them prone to component misalignment during long-term use. This leads to unstable demolding results and may even cause damage to the workpiece or die due to improper force, increasing the risk of malfunctions. Regarding die clamping, existing equipment has poor flexibility in adjusting clamping dimensions, often only adapting to specific die specifications. When processing valve and pipe castings and forgings of different sizes, frequent changes to clamping components are necessary, extending production preparation time and reducing equipment versatility. In addition, traditional clamping structures rely solely on a single clamping force to fix the die, which is prone to loosening due to vibration or impact during stamping, affecting processing accuracy and production safety. In response to this technical problem, this application proposes a high-efficiency valve and pipeline mold steel casting and forging. Utility Model Content

Simultaneously, a bidirectional threaded rod drives the clamping plate to move, a sliding groove limits the movement to adapt to different molds, and a wedge-shaped locking block, limit rod, and spring form a double fixation, enhancing the stability of the device and improving its applicability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of a high-efficiency valve pipe mold steel casting and forging, including a processing table 1 and a support plate 5. A fixed plate 2 is fixedly connected to the top of the processing table 1. An electric push rod 11 is provided at the middle of the top of the fixed plate 2. A fixed rod 16 is fixedly connected to the bottom of the push block 17. A support frame 14 is fixedly connected to the bottom of the fixed rod 16. A rotating shaft passes through the inside of the support frame 14. A rotating wheel 13 is rotatably connected to the outer wall of the rotating shaft. An inclined block 12 is provided on the outer wall of the rotating wheel 13. The outer wall of the inclined block 12 is fixedly connected to the drive end of the electric push rod 11. A protective box 6 is provided at the middle of the top of the fixed plate 2. The bottom of the mold 4 is provided on the top outer wall of the protective box 6. A spring 15 is sleeved on the outside of the fixed rod 16. The fixed rod 16 passes through the top of the protective box 6.

[0024] Specifically, after the raw material of the valve fitting is stamped to form the valve pipe, the electric push rod 11 on the top of the fixed plate 2 is activated, and its drive end will drive the inclined block 12 to move horizontally. Since the inclined block 12 is set on the outer wall of the rotating wheel 13, and the rotating wheel 13 is rotatably connected to the inside of the support frame 14 through a rotating shaft, as the inclined block 12 moves, the rotating wheel 13 will roll along the outer wall of the inclined block 12, causing the support frame 14 to move upward. Since the top of the support frame 14 is fixedly connected to the fixed rod 16, and the top of the fixed rod 16 is connected to the push block 17, the fixed rod 16 will move upward with the support frame 14, thereby driving the push block 17 to move upward. Finally, the push block 17 pushes out the valve pipe placed on the mold 4 on the top of the protective box 6. The protective box 6 at the top center of the fixed plate 2 guides the fixed rod 16 to prevent it from shifting during movement. The bottom of the inclined block 12 is provided with a protrusion, and the top of the fixed plate 2 is provided with a strip groove. The protrusion moves in the strip groove to prevent the inclined block 12 from being misaligned during movement. The protective box 6 provides buffer protection through the fixed rod 16 and the spring 15. The two ends of the spring 15 are fixed to the inner top wall of the protective box 6 and the support frame 14 respectively to prevent the spring 15 from shaking and misaligning when compressed. The protective box 6 is a hollow box. The center of the mold 4 has a push block 17 hole to allow the push block 17 to pass through. Through the cooperation of the electric push rod 11, the inclined block 12, the rotating wheel 13 and other structures, the automatic and rapid ejection of the stamped valve and pipe finished product is realized, reducing manual operation time and improving production efficiency.

[0025] Reference Figure 1 , Figure 3 and Figure 4The top of the fixed plate 2 has a groove 26, and a fixed block 20 is fixedly connected to the middle of the groove 26. A bidirectional threaded rod 19 is rotatably connected inside the fixed block 20. A slider 21 is threadedly connected to the outer wall of the bidirectional threaded rod 19. A clamping plate 3 is fixedly connected to the top of the slider 21. A limit rod 24 is set inside the top of the clamping plate 3. A locking block 22 is set on the limit rod 24. The outer wall of the locking block 22 is fixedly connected to the outer wall of the mold 4. A spring 23 is sleeved on the outer wall of the limit rod 24. The bottom of the limit rod 24 is hemispherical. The design features a wedge-shaped locking block 22 with a hemispherical limiting groove at the top. A motor 18 is located at the left end of the bidirectional threaded rod 19. A dustproof strip is installed at the top of the slide groove 26. A support block 25 is fixedly connected to the top of the support plate 5. A hydraulic rod 7 passes through the support block 25. A guide post 10 is fixedly connected between the support block 25 and the fixed plate 2. A connecting plate 8 is fixedly connected to the drive end of the hydraulic rod 7. A pressure plate 9 is installed at the bottom of the connecting plate 8. The guide post 10 passes through the interior of the connecting plate 8.

[0026] Specifically, when using this device, the starter motor 18 drives the bidirectional threaded rod 19 to rotate, causing the slider 21 to move. Because the slider 21 is limited by the slide groove 26, the sliders 21 on both sides of the bidirectional threaded rod 19 cause the clamping plates 3 to move in opposite directions along the slide groove 26, thereby achieving clamping and fixing of molds 4 of different sizes. During clamping, the wedge-shaped locking block 22 on the outer wall of the mold 4 presses against the hemispherical bottom of the inner limiting rod 24 at the top of the clamping plate 3, causing the limiting rod 24 to move upward and compress the second spring 23. When the locking block 22 moves to the appropriate position, the second spring 23 resets and pushes the limiting rod 24 downward, causing the limiting rod 24 to engage in the hemispherical limiting groove at the top of the locking block 22, further enhancing the fixing effect of the mold 4. The dustproof strip at the top of the slide groove 26 prevents impurities from entering and affecting the movement of the slider 21. At this time, after the mold 4 is clamped, the raw material for stamping valve fittings is put into the mold 4. At this time, the hydraulic rod 7 on the support plate 5 is driven to move the connecting plate 8 up and down along the guide column 10, which drives the pressure plate 9 to process the raw material inside the mold 4. The guide column 10 can ensure that the connecting plate 8 moves smoothly. The clamping plate 3 is driven to move through the bidirectional threaded rod 19, which can flexibly adjust the clamping size to adapt to different specifications of mold 4 and improve the applicability of the device. Through the cooperative design of the locking block 22 and the limiting rod 24, the limiting is added on the basis of clamping by the clamping plate 3, which improves the stability of fixing the mold 4.

[0027] Working principle: When using this device, the starter motor 18 drives the bidirectional threaded rod 19 to rotate. Under the limiting action of the slide groove 26, the sliders 21 on both sides of the bidirectional threaded rod 19 drive the clamping plates 3 to move in opposite directions, achieving initial clamping of molds 4 of different sizes. During the clamping process, the wedge-shaped locking block 22 on the outer wall of the mold 4 presses the limiting rod 24 at the top of the clamping plate 3, causing it to move upward and compress the second spring 23. After the locking block 22 is in place, the second spring 23 resets and pushes the limiting rod 24 into the limiting groove at the top of the locking block 22, further fixing the mold 4. After the mold 4 is fixed, the raw material is put into it. Then, the hydraulic rod 7 on the support plate 5 is driven to make the connecting plate 8 move smoothly along the guide column 10, driving the pressure plate 9 to perform stamping processing on the raw material in the mold 4. After processing, the electric push rod 11 is activated to drive the inclined block 12 to move horizontally, causing the rotating wheel 13 to roll along the outer wall of the inclined block 12 and drive the support frame 14 to move upward. Then, the fixed rod 16 drives the push block 17 to move upward, pushing out the finished valve pipe on the mold 4. The protective box 6 guides the fixed rod 16, the spring 15 provides buffer protection, and the bottom protrusion of the inclined block 12 moves in the strip groove to avoid misalignment, so as to achieve flexible fixing of molds 4 of different specifications and automatic ejection of finished products, improving production efficiency and applicability.
