Description

Technical Field

[0001] This utility model relates to the field of forging technology, and in particular to a connecting device for a die forging hydraulic press that facilitates mold replacement. Background Technology

[0002] A die forging hydraulic press is a pressure processing device that uses the principle of hydraulic transmission to forge metal. It uses high-pressure fluid generated by the hydraulic system to push the piston in the hydraulic cylinder, thereby driving the slide (or moving beam) to move up and down, forming the metal billet placed in the mold.

[0003] Among them, the die forging hydraulic press includes high-pressure forming, which can generate extremely high pressure and is suitable for die forging large and complex-shaped metal parts. Through hydraulic and electrical control systems, pressure, speed and stroke can be precisely controlled to ensure forming quality. It can adapt to metal blanks of different materials and shapes, and can process a variety of parts by changing the mold. Die forging hydraulic presses usually have a high degree of automation and high production efficiency.

[0004] In existing die forging hydraulic presses, metal billets are placed in the lower die, and then hydraulic oil enters the main hydraulic cylinder, pushing the piston downward. The piston, connected to the slider, moves the upper die downward, applying pressure to the billet in the lower die. However, when producing different metal billets, heavy tools or considerable force are required to disassemble the die, increasing the risk of injury to operators. At the same time, due to the difficulty of operation, the die is easily damaged, requiring additional maintenance or replacement costs. Utility Model Content

[0031] Please see Figure 1-4 This utility model provides a technical solution: a connecting device for a forging hydraulic press that facilitates mold replacement, including a support base 1;

[0032] A limit device is provided on the support base 1;

[0033] The limiting device includes a lower mold 4, two rotating threaded rods 3, and four sliding rods 2. The four sliding rods 2 are arranged in pairs, and the two sets of sliding rods 2 are slidably connected to the outer walls of the upper two sides of the support base 1. The upper surface of the support base 1 has a placement groove 5. The lower outer wall of the lower mold 4 is slidably connected to the interior of the placement groove 5. The two rotating threaded rods 3 are threadedly connected to the outer walls of the support base 1 on both sides. The lower mold 4 has a first limiting plate groove 13 on both sides of the lower end. The inner walls of the placement groove 5 on both sides have a second limiting plate groove 17. The interiors of the two second limiting plate grooves 17 are slidably connected to limiting plates 18. The ends of the two limiting plates 18 near the first limiting plate grooves 13 slide into the interior of the placement groove 5 and contact the inner walls of the corresponding first limiting plate grooves 13. The ends of the two sets of sliding rods 2 near the limiting plates 18 slide into the interior of the second limiting plate grooves 17 and are fixedly connected to the ends of the corresponding limiting plates 18. The ends of the two rotating threaded rods 3 near the limiting plates 18 are threaded into the second limiting plates 17. The interior of the plate groove 17 is rotatably connected to one end of the corresponding limiting plate 18. The interior of the two protrusions on the upper surface of the support base 1 is slidably connected to the fixed limiting block 14. The interior of the two second limiting plate grooves 17 is correspondingly connected to the interior of the two protrusions on the upper surface of the support base 1. The upper surface of the two limiting plates 18 is provided with a fixed limiting block groove 15. The end of the two fixed limiting blocks 14 near the fixed limiting block groove 15 slides into the interior of the second limiting plate groove 17 and contacts the inner wall of the corresponding fixed limiting block groove 15. The upper end of the two protrusions on the upper surface of the support base 1 is slidably connected to the pull rod 9. The end of the two pull rods 9 near the fixed limiting block 14 slides into the interior of the two protrusions on the upper surface of the support base 1 and is fixedly connected to one end of the corresponding fixed limiting block 14. The outer wall of the two pull rods 9 is sleeved with a return spring 16. The two ends of the two return springs 16 are respectively fixedly connected to one end of the corresponding fixed limiting block 14 and the inner wall of the two protrusions on the upper surface of the support base 1.

[0034] The support base 1 has four support columns with a top plate 7 fixedly connected to the ends away from the support base 1. The upper surface of the top plate 7 has two sliding rods B6 slidably connected. The support base 1 has a mounting seat 8 with the four corners of the mounting seat 8 slidably connected to the outer walls of the four support columns on the support base 1. The ends of the two sliding rods B6 near the mounting seat 8 extend slidably to the outside of the top plate 7 and are fixedly connected to the upper surface of the mounting seat 8. The lower surface of the top plate 7 has a cylinder 10 fixedly connected. The output end of the cylinder 10 is fixedly connected to the upper surface of the mounting seat 8. The lower surface of the mounting seat 8 has two conical block grooves 11. The support base 1 has an upper mold 12 with the outer walls of the two conical blocks at the upper end of the upper mold 12 slidably connected to the interior of the corresponding conical block grooves 11. The fixing bolts threaded to one end of the two conical blocks on the upper mold 12 extend threadedly to the outside of the conical blocks near the conical block grooves 11 and are threadedly connected to the interior of the grooves at one end of the conical block grooves 11.

[0035] Furthermore, when using this device, it is started by connecting to an external power source. First, the metal blank is placed in the lower mold 4. Then, the output end of the cylinder 10 moves downward, causing the mounting base 8 to move downward, simultaneously moving the upper mold 12 downward. The upper mold 12 then applies pressure to the blank in the lower mold 4 to shape it. When it is necessary to remove the lower mold 4, the pull rod 9 is pulled upward, causing the fixed limit block 14 to move upward, simultaneously causing the return spring 16 to retract. Then, the fixed limit block 14 moves upward... To disengage the other end of the mold from the inside of the fixed limiting block groove 15, simultaneously rotate the threaded rod 3 to make it move in the opposite direction. This causes the limiting plate 18 to move in the opposite direction, causing the outer wall of its other end to disengage from the inside of the first limiting plate groove 13. Then, pull the lower mold 4 to remove it from the support base 1. When it is necessary to remove the upper mold 12, turn the fixing bolt at one end of the conical block on the upper mold 12 to rotate it so that the outer wall of its other end disengages from the groove in one end of the conical block groove 11. Then, pull the upper mold 12 to remove it from the mounting base 8.

[0036] By pulling the lever 9 upward in the limiting device, the fixed limiting block 14 is moved upward, which in turn causes the return spring 16 to retract. Then, by moving the fixed limiting block 14 upward, its other end is disengaged from the inside of the fixed limiting block groove 15. At the same time, the rotating threaded rod 3 is turned to rotate it in the opposite direction, which causes the limiting plate 18 to move in the opposite direction, so that its other outer wall is disengaged from the inside of the first limiting plate groove 13. Then, the lower mold 4 can be pulled to remove it from the support base 1. This method of disassembling the lower mold 4 is simple and quick, avoiding the need for operators to use heavy tools to disassemble the lower mold 4, thereby effectively reducing the workload of operators and improving the practicality and flexibility of the equipment.

[0041] Pull rod 9: Pull rod 9 is used for manual operation. By pulling it, it moves up and down, thereby driving the movement of the fixed limit block 14. It provides a means of manually controlling the movement of the fixed limit block 14, which facilitates the disassembly and installation of the lower mold 4.

[0042] Cylinder 10: Cylinder 10 is the power source that drives the mounting base 8 and the upper mold 12 to move up and down. Through air pressure drive, it realizes the rapid and stable up and down movement of the mounting base 8 and the upper mold 12.

[0043] Upper mold 12: The upper mold 12 is another key component that works with the lower mold 4 to form the metal blank. It works with the lower mold 4 to form the metal blank by applying pressure.
