Description

Technical Field

[0001] This invention relates to the field of hot forging press technology, specifically a hot forging press with a pneumatic friction clutch. Background Technology

[0002] Hot forging presses are modern forging equipment used for precision metal forming, offering advantages such as high precision, high productivity, and automation compatibility. To enhance safety, hot forging presses are typically equipped with pneumatic friction clutches. The working principle of the pneumatic friction clutch-brake system in a hot forging press is as follows: under normal conditions, spring force separates the clutch friction disc and presses the brake friction disc; during operation, air pressure presses the clutch friction disc and disengages the brake, ensuring rapid response and safe braking. However, when the pneumatic friction clutch wears or sticks, or the control system malfunctions, the slide may move unexpectedly, potentially injuring operators. Because the equipment requires manual operation to remove the formed material during material forming, spray release agent onto the upper and lower dies, and then place new material into the lower die, this process inevitably requires operators to intervene between the upper and lower dies, creating certain safety hazards in the production process. To facilitate automatic material handling and mold release agent spraying, a hot forging press with a pneumatic friction clutch is provided. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting up a spraying mechanism, when the clamping seat moves out from above the lower mold, the rotating shaft rotates, driving the gear plate to rotate. The gear teeth contact the bevel gear, so that when the gear plate rotates, it drives the bevel gear to rotate one revolution. The rotation of the bevel gear drives the movable cylinder to make a circumferential displacement, thereby driving the displacement rod to swing once. The displacement plate moves back and forth along the inner wall of the guide frame once. During this process, the release agent in the liquid inlet pipe is delivered to the displacement plate and sprayed out through the nozzle, automatically spraying the release agent on the lower mold and the upper mold. This design can facilitate the automatic spraying of release agent on the lower mold and the upper mold.

[0016] 2. By setting up a moving mechanism, the clamping seat moves to the top of the lower mold, and then the rotating plate moves downward a certain distance. The two clamping plates approach each other to clamp the formed material. The rotating plate moves upward to move the formed material out of the lower mold. Then the rotating plate continues to rotate until the placement frame moves to the top of the lower mold. At this time, the bottom plate rotates and separates from the material, and the unprocessed material falls into the lower mold. Then the rotating plate continues to rotate, driving the clamping seat to move above the guide block for resetting. The clamping plates release the clamping of the formed material, and the material slides into the collection frame through the guide block for collection. This facilitates the automatic removal of the formed material and the automatic placement of the unprocessed material into the inner cavity of the lower mold. The material handling process is automated, eliminating the need for workers to intervene in dangerous operations between the upper and lower molds, improving work efficiency while ensuring production safety.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0029] Please see Figures 1 to 9 In this embodiment of the invention, a hot forging press with a pneumatic friction clutch includes a machine body 1, a pneumatic friction clutch 2 installed on one side of the machine body 1, a lower template 3 fixedly connected to the inner cavity of the machine body 1, an upper template 4 installed above the lower template 3 in the inner cavity of the machine body 1, a lower mold 5 fixedly connected to the outer wall of the lower template 3, an upper mold 6 fixedly connected to the outer wall of the upper template 4, the material is moved by a moving mechanism 7, and the release agent is sprayed by a spraying mechanism 8.

[0030] The spraying mechanism 8 includes a guide frame 801, which is symmetrically fixed to both ends of the body 1. The moving mechanism 7 includes an installation cylinder 701, which is located at one end of the body 1. A guide block 702 is provided on one side of the installation cylinder 701, and a collection frame 703 is provided on one side of the guide block 702. A first motor 704 is provided in the inner cavity of the installation cylinder 701. The output end of the first motor 704 is connected to a rotating seat 705. A rotating shaft 706 is fixedly connected to the top of the rotating seat 705. An electric push rod 707 is installed on the top of the rotating seat 705 on one side of the rotating shaft 706. A rotating plate 708 is connected to the output end of the electric push rod 707. The rotating plate 708 is slidably connected to the outer wall of the rotating shaft 706.

[0031] The moving mechanism 7 also includes a clamping seat 709, which is fixedly connected to one end of a rotating plate 708. A placement frame 714 is fixedly connected to the other end of the rotating plate 708. A clamping plate 710 is symmetrically slidably connected inside the clamping seat 709. A second motor 711 is installed on one side of the clamping seat 709. A threaded rod 712 is connected to the output end of the second motor 711. The threaded rod 712 passes through the clamping plate 710. A base plate 715 is rotatably connected to the bottom end of the placement frame 714. A spur gear 716 is fixedly connected to the top end of the base plate 715. The spur gear 716 is rotatably connected to the inside of the placement frame 714. A toothed plate 717 is slidably connected to the outer wall of the spur gear 716 inside the placement frame 714. A pressing plate 718 is fixedly connected to one end of the toothed plate 717. A first spring 719 is connected between the pressing plate 718 and the placement frame 714. A vertical rod 713 is fixedly connected to the bottom end of the guide frame 801.

[0032] In this embodiment: the second motor 711 drives the threaded rod 712 to rotate, and the rotation of the threaded rod 712 drives the two clamping plates 710 to move in opposite directions. The movement of the two clamping plates 710 clamps or releases the material.

[0033] The first motor 704 drives the rotating seat 705 to rotate. The rotation of the rotating seat 705 drives the rotating plate 708 to rotate via the rotating shaft 706 and the electric push rod 707. The rotation of the rotating plate 708 drives the clamping seat 709 and the placement frame 714 to perform circumferential displacement. The operation of the electric push rod 707 drives the rotating plate 708 to perform upward or downward displacement operations.

[0034] The upper mold 6 moves downwards to contact the lower mold 5, performing pressure forming on the material inside the lower mold 5. Unprocessed material is placed in the placement frame 714. After completion, the electric push rod 707 rotates, causing the rotating plate 708 to move upwards a certain distance. The rotating plate 708 then rotates clockwise, moving the clamping seat 709 above the lower mold 5 (the lower mold 5 has an ejector device at the bottom of its forming cavity, which automatically ejects the formed material upwards a certain distance after pressure forming; this ejector device is a mature existing technology, and its structure and operating principle will not be described in detail here). The rotating plate 708 then moves downwards a certain distance, and the two clamping plates 710 come closer together to clamp the formed material. The rotating plate 708 moves upwards, removing the formed material from the lower mold 5. The rotating plate 708 then continues to rotate clockwise. The process continues until the placement frame 714 moves above the lower mold 5. At this point, the extrusion plate 718 contacts the vertical rod 713, pushing the extrusion plate 718 to move and compress the first spring 719. The displacement of the extrusion plate 718 causes the toothed plate 717 to move, which in turn causes the spur gear 716 to rotate. The rotation of the spur gear 716 causes the base plate 715 to rotate, separating it from the material. The unprocessed material falls into the lower mold 5 for easy processing in the next step. Afterward, the rotating plate 708 continues to rotate, causing the clamping seat 709 to move above the guide block 702 for resetting. The clamping plate 710 releases its grip on the formed material, and the material slides through the guide ramp of the guide block 702 into the collection frame 703 for collection. This facilitates the automatic removal of the formed material and the automatic placement of the unprocessed material into the inner cavity of the lower mold 5.

[0035] Please refer to this carefully. Figures 6 to 9 The spraying mechanism 8 also includes a displacement plate 802, which is slidably connected to the inner wall of the guide frame 801. The top and bottom ends of the displacement plate 802 are fixedly connected to a nozzle 803. One end of the displacement plate 802 is fixedly connected to a cylinder 809, and the other end of the displacement plate 802 is fixedly connected to an inlet pipe 804. One end of the body 1 is provided with a mounting bracket 805. The outer wall of the mounting bracket 805 is rotatably connected to a connecting shaft 806 and a rotating column 814. The connecting shaft 806 is located above the rotating column 814. One end of the connecting shaft 806 is rotatably connected to a displacement rod 807. The bottom end of the displacement rod 807 is fixedly connected to a displacement frame 808, and the cylinder 809 is slidably connected to the inner wall of the displacement frame 808.

[0036] The spraying mechanism 8 also includes a first connector 810, which is rotatably connected to the top of a guide frame 801. A telescopic rod 811 is fixedly connected to the top of the first connector 810. A second connector 812 is fixedly connected to one end of the telescopic rod 811. The second connector 812 is rotatably connected to the displacement frame 808. A second spring 813 is connected between the first connector 810 and the second connector 812 on the outer wall of the telescopic rod 811. A rotating frame 816 is fixedly connected to one end of the rotating column 814. A bevel gear 815 is fixedly connected to the outer wall of the rotating column 814. A gear disk 818 is fixedly connected to the top of the rotating shaft 706. Gear teeth 819 are provided on the outer wall of the gear disk 818. A movable cylinder 817 is rotatably connected to one end of the rotating frame 816. The movable cylinder 817 is slidably connected to the outer wall of the displacement rod 807.

[0037] In this embodiment: when the clamping seat 709 moves out from above the lower mold 5, the rotating shaft 706 rotates, causing the gear disk 818 to rotate. The gear teeth 819 contact the bevel gear 815, thus causing the bevel gear 815 to rotate one revolution when the gear disk 818 rotates. The rotation of the bevel gear 815 causes the rotating column 814 to rotate, which in turn causes the rotating frame 816 to rotate. The rotation of one end of the rotating frame 816 causes the movable cylinder 817 to perform circumferential displacement. The movable cylinder 817 slides on the outer wall of the displacement rod 807, thereby causing the displacement rod 807 to move once. The oscillating displacement rod 807 rotates, causing the displacement frame 808 to move. When the displacement frame 808 moves, the cylinder 809 slides on the inner wall of the displacement frame 808. The displacement of the cylinder 809 causes the displacement plate 802 to slide laterally within the guide frame 801, thereby causing the displacement plate 802 to move back and forth along the inner wall of the guide frame 801. During this process, the release agent in the liquid inlet pipe 804 is delivered to the displacement plate 802 and sprayed out through the nozzle 803, automatically spraying the release agent onto the lower mold 5 and the upper mold 6, which facilitates the automatic spraying of the release agent onto the lower mold 5 and the upper mold 6.

[0038] The second connector 812 is moved away from the first connector 810 by the elastic force of the second spring 813, so that the displacement frame 808 is located on the side away from the first connector 810 when it is not subjected to other forces, thereby keeping the displacement plate 802 at one end of the guide frame 801.

[0039] Please refer to this carefully. Figures 2 to 5 The outer wall of the clamping plate 710 fits against the inner wall of the clamping seat 709. The outer wall of the clamping plate 710 is provided with a threaded hole, and the outer wall of the threaded rod 712 is symmetrically provided with external threads, which match the threaded hole.

[0040] In this embodiment: the second motor 711 drives the threaded rod 712 to rotate, and the rotation of the threaded rod 712 drives the two clamping plates 710 to move in opposite directions.

[0041] Please refer to this carefully. Figures 2 to 5 One end of the extrusion plate 718 is provided with an inclined surface, and the outer wall of the toothed plate 717 is provided with a tooth groove, which matches the spur gear 716.

[0042] In this embodiment: the placement frame 714 moves above the lower mold 5. At this time, the extrusion plate 718 contacts the vertical rod 713, pushing the extrusion plate 718 to move and extruding the first spring 719. The displacement of the extrusion plate 718 causes the toothed plate 717 to move, and the displacement of the toothed plate 717 causes the spur gear 716 to rotate. The rotation of the spur gear 716 causes the base plate 715 to rotate.

[0043] Please refer to this carefully. Figures 6 to 9 The diameter of the toothed disc 818 is four times the diameter of the bevel gear 815. The gear teeth 819 mesh with the bevel gear 815 and occupy one-quarter of the circumference of the toothed disc 818.

[0044] In this embodiment: when the clamping seat 709 moves out from above the lower mold 5, the rotating shaft 706 rotates and drives the gear disk 818 to rotate. The gear teeth 819 come into contact with the bevel gear 815, so that when the gear disk 818 rotates, it drives the bevel gear 815 to rotate one revolution. The rotation of the bevel gear 815 drives the rotating column 814 to rotate.

[0045] Please refer to this carefully. Figures 6 to 9 The inner wall of the movable cylinder 817 is in contact with the outer wall of the displacement rod 807.

[0046] In this embodiment: the rotating column 814 rotates to drive the rotating frame 816 to rotate, and the rotating frame 816 rotates at one end to drive the movable cylinder 817 to perform circumferential displacement. The movable cylinder 817 slides on the outer wall of the displacement rod 807, thereby driving the displacement rod 807 to swing once.

[0047] Please refer to this carefully. Figures 6 to 9 The inner wall of the displacement frame 808 is in contact with the outer wall of the cylinder 809.

[0048] In this embodiment: the displacement rod 807 rotates to drive the displacement frame 808 to move, and the cylinder 809 slides on the inner wall of the displacement frame 808 when the displacement frame 808 moves.

[0049] Please refer to this carefully. Figures 6 to 9 The outer wall of the displacement plate 802 is in contact with the inner wall of the guide frame 801.

[0050] In this embodiment: when the displacement frame 808 is displaced, the cylinder 809 slides on the inner wall of the displacement frame 808, and the displacement of the cylinder 809 causes the displacement plate 802 to slide laterally within the guide frame 801.

[0051] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
