[0008] A fixing plate, which is fixedly connected inside the press frame below the pressing plate.

[0009] A rotating motor is fixedly connected inside a fixed plate;

[0010] A pressing and fixing table is fixedly connected to the top of the rotating motor, and the pressing and fixing table is fixedly connected to the output shaft of the rotating motor.

[0011] Preferably, the pressing connecting rod is movably connected inside the guide plate. Four guide posts are arranged on the top of the pressing plate, and all four guide posts are movably connected inside the guide plate. A limit card slot for restricting the metal blank is arranged on the top of the pressing and fixing table.

[0012] Preferably, an annular plate is fixedly connected to the top of the fixed plate. A barrier net is fixedly connected to the outer wall of the pressing and fixing table inside the annular plate. A fan blade plate is fixedly connected to the bottom of the barrier net.

[0013] Preferably, a notch is arranged at the annular plate. An inclined discharge plate is fixedly connected inside the notch arranged at the annular plate. Several raised blocks are arranged at the position corresponding to the inner wall of the annular plate near the top of the barrier net.

[0014] Preferably, a collection box is arranged at the position corresponding to the inclined discharge plate outside the inclined discharge plate, and ventilation holes are arranged on the front and back of the collection box.

[0015] Preferably, the removing mechanism includes a support frame. There are two support frames, and the two support frames are respectively fixedly connected to the left and right sides of the pressing plate. Pneumatic telescopic rods are fixedly connected inside both support frames. Removing heads are movably connected to the bottom of the pressing plate inside both pneumatic telescopic rods.

[0016] Preferably, springs are fixedly connected to the outer walls of the removing heads, and the springs are fixedly connected to the corresponding pneumatic telescopic rods.

[0017] Preferably, two cylinders are fixedly connected to the outer wall of the press frame. Pulling rods are fixedly connected to the bottoms of the two cylinders. The two pulling rods respectively penetrate through the press frame and are fixedly connected to both sides of the pressing plate. Connecting air pipes are fixedly connected to the bottoms of the two pulling rods. The two connecting air pipes respectively penetrate through the corresponding pulling rods and are fixedly connected to the corresponding pneumatic telescopic rods.

[0018] The present invention provides a pressing device for casting metal blanks. It has the following beneficial effects:

[0019] 1. The pressing equipment for the cast metal blank drives the pressing fixing table to rotate through a rotating motor, and the blank rotates along with it. Under the action of rotation, the metal scraps are affected by centrifugal force and move around, falling off the top of the rotating motor to the top of the blocking net. Under the action of centrifugal force, the metal scraps break away from the top of the blocking net and slide down along the inclined discharge plate into the collection box, so as to prevent the metal scraps from continuously accumulating in the processing area and improve the pressing processing speed.

[0020] 2. When the pressing plate rises in the pressing equipment for the cast metal blank, the pulling rod drives the air cylinder to rise and the air cylinder contracts. The air cylinder sends the gas back into the pneumatic telescopic rod through the connecting air pipe again, causing the pneumatic telescopic rod to extend. The pneumatic telescopic rod pushes the scraping head to scrape the bottom of the pressing plate. When the two scraping heads collide, they vibrate, promoting the falling off of the scraps at the bottom of the pressing plate, preventing the metal chips from adhering to the bottom of the pressing plate, and further preventing the metal scraps adhering to the bottom from affecting the quality of the metal blank forming, which can play a role in improving the processing speed.

[0021] 3. In the pressing equipment for the cast metal blank, the metal scraps adhered to the bottom of the pressing plate are shoveled off by the pneumatic telescopic rod through the scraping head and fall onto the metal blank. The metal blank is driven to rotate by the pressing fixing table, and the falling metal scraps are thrown onto the top of the blocking net and enter the collection box through the inclined discharge plate under the action of centrifugal force through the blocking net for collection, collecting the scraps shoveled off from the bottom of the pressing plate, reducing the processing steps for the scraps, and being able to improve the processing speed.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0033] Embodiment 1: Please refer to Figure 1-5 , the present invention provides a technical solution: a casting metal blank pressing device, including a press frame 1, a pressing motor 2 is fixedly connected to the top of the press frame 1, a runner 3 is fixedly connected to the front of the pressing motor 2, and the runner 3 is fixedly connected to the output shaft of the pressing motor 2. The front of the runner 3 is movably connected to a pressing connecting rod 4, the bottom of the pressing connecting rod 4 is fixedly connected to a pressing plate 5, a guide plate 6 is fixedly connected inside the press frame 1 at the top of the pressing plate 5, a collection mechanism 7 is fixedly connected inside the press frame 1 at the bottom of the pressing plate 5, and a shoveling mechanism 8 is fixedly connected to the outer wall of the pressing plate 5;

[0034] The collection mechanism 7 includes:

[0035] A fixed plate 701, and the fixed plate 701 is fixedly connected inside the press frame 1 at the bottom of the pressing plate 5;

[0036] A rotating motor 702, and the rotating motor 702 is fixedly connected inside the fixed plate 701;

[0037] A pressing fixing table 703, and the pressing fixing table 703 is fixedly connected to the top of the rotating motor 702, and the pressing fixing table 703 is fixedly connected to the output shaft of the rotating motor 702.

[0038] The pressing connecting rod 4 is movably connected inside the guide plate 6. Four guide posts are provided on the top of the pressing plate 5, and all four guide posts are movably connected inside the guide plate 6. A limit card slot for restricting the metal blank is provided on the top of the pressing fixed table 703.

[0039] Place the press frame 1 on a plane, then place the cast metal blank heated to a suitable temperature in the limit card slot on the top of the pressing fixed table 703, and start the equipment. The pressing motor 2 will drive the runner 3 to rotate. The rotation of the runner 3 will drive the pressing plate 5 to move through the pressing connecting rod 4. Under the restriction of the guide plate 6, the pressing connecting rod 4 will make the pressing plate 5 move up and down repeatedly to continuously press the metal blank. When the fan blade plate 705 moves upward, start the rotating motor 702 to drive the pressing fixed table 703 to rotate. When the pressing fixed table 703 rotates, it will drive the workpiece to rotate together through the limit card slot. When the pressing plate 5 presses downward, stop the rotating motor 702. Pressing the metal blank will cause some metal scraps to fall off the surface of the metal blank. The rotation of the rotating motor 702 will act on the metal scraps, and the metal scraps will be affected by the centrifugal force under the action of rotation and move around, and fall off from the top of the rotating motor 702.

[0040] The top of the fixing plate 701 is fixedly connected with an annular plate 707. A blocking net 704 is fixedly connected to the outer wall of the pressing fixed table 703 inside the annular plate 707. The bottom of the blocking net 704 is fixedly connected with a fan blade plate 705.

[0041] When the pressing fixed table 703 rotates, it will synchronously drive the blocking net 704 and the fan blade plate 705 to rotate. The rotation of the fan blade plate 705 will push the air to generate a downward flowing air current, so that the metal scraps falling off from the top of the rotating motor 702 are adsorbed to the top of the blocking net 704 under the action of the air current.

[0042] There is a notch in the annular plate 707. An inclined discharge plate 708 is fixedly connected in the notch provided in the annular plate 707. Several raised blocks 706 are provided at the corresponding positions on the inner wall of the annular plate 707 near the top of the blocking net 704.

[0043] The scraps on the top of the blocking net 704 will be rotated together with the blocking net 704 on the top of the blocking net 704, and will approach the inner wall of the annular plate 707 under the action of the centrifugal force. When approaching the raised block 706, it will be pushed by the raised block 706 to perform a circular motion. When the raised block 706 pushes the scraps to move to the notch provided in the annular plate 707, they will break away from the top of the blocking net 704 under the action of the centrifugal force and slide down along the inclined discharge plate 708.

[0044] A collection box 709 is provided at the corresponding position outside the inclined discharge plate 708, and ventilation holes are provided on both the front and back of the collection box 709.

[0045] The slag falling from the inclined plate 708 will slide into the interior of the collection box 709. The airflow generated by the rotation of the fan blade plate 705 will blow onto the plane at the bottom of the fixed plate 701. Then, under the guiding action of the fixed plate 701, the airflow will flow to the front and rear sides. The airflow flowing backward will pass through the openings on the collection box 709 and pass through the collection box 709, which will blow the metal slag inside the collection box 709 backward, preventing the slag from accumulating excessively inside the collection box 709, making the slag stacked more evenly inside the collection box 709, and increasing the space utilization rate inside the collection box 709.

[0046] Embodiment 2: Please refer to Figure 1-8 , based on Embodiment 1, the present invention provides a technical solution:

[0047] The scraping mechanism 8 includes a support frame 801. There are two support frames 801, and the two support frames 801 are respectively fixedly connected to the left and right sides of the pressing plate 5. Inside both support frames 801, a pneumatic telescopic rod 802 is fixedly connected. Inside the two pneumatic telescopic rods 802, a scraping head 803 is movably connected to the bottom of the pressing plate 5. The support frame 801 plays a role in positioning the pneumatic telescopic rod 802, making the scraping head 803 fit the bottom of the pressing plate 5.

[0048] When pressing the metal blank at the bottom of the pressing plate 5, there will be some metal slag sticking to the bottom of the pressing plate 5. When the pressing plate 5 is pressing, the slag sticking to the bottom of the pressing plate 5 will participate in the pressing, affecting the surface quality of the blank. The two pneumatic telescopic rods 802 can extend inward to push the corresponding scraping head 803 inward, so that the scraping head 803 shovels the bottom of the pressing plate 5, preventing metal slag from sticking to the bottom of the pressing plate 5.

[0049] The metal slag sticking to the bottom of the pressing plate 5 is shoveled off by the pneumatic telescopic rod 802 through the scraping head 803. These slag will fall onto the metal blank. The metal blank will be driven by the pressing and fixing table 703 to rotate, so that the falling metal slag is thrown onto the top of the barrier net 704 and, under the action of the barrier net 704 and the centrifugal force, enters the interior of the collection box 709 through the inclined plate 708 and is collected.

[0050] On the outer wall of the scraping head 803, a spring 804 is fixedly connected, and the spring 804 is fixedly connected to the corresponding pneumatic telescopic rod 802. The scraping head 803 can move relative to the pneumatic telescopic rod to make the spring 804 contract.

[0051] When the two pneumatic telescopic rods 802 extend inward, they will cause the two scraping heads 803 to collide with each other. When the scraping heads 803 collide with each other, the two springs 804 can be compressed, giving the scraping heads 803 room to move. This causes the two scraping heads 803 to vibrate within a certain space when they collide with each other, promoting the shedding of the debris at the bottom of the pressing plate 5.

[0052] Two cylinders 805 are fixedly connected to the outer wall of the press frame 1. At the bottom of each of the two cylinders 805, a pulling rod 806 is fixedly connected. The two pulling rods 806 each pass through the press frame 1 and are respectively fixedly connected to both sides of the pressing plate 5. At the bottom of each of the two pulling rods 806, a connecting air pipe 807 is fixedly connected. The two connecting air pipes 807 each pass through the corresponding pulling rod 806 and are fixedly connected to the corresponding pneumatic telescopic rod 802. The cylinder 805 can extract the air inside the pneumatic telescopic rod 802 and send air into the pneumatic telescopic rod 802 through the connecting air pipe 807.

[0053] When the pressing plate 5 moves downward for pressing, the pressing plate 5 will drive the cylinder 805 downward together through the pulling rod 806. When the cylinder 805 moves downward, the cylinder 805 will be stretched, expanding the volume of the cylinder 805. The cylinder 805 will extract the air inside the pneumatic telescopic rod 802 through the connecting air pipe 807, thereby causing the pneumatic telescopic rod 802 to contract, so that the scraping head 803 is pulled away from the bottom surface of the pressing plate 5. When the pressing plate 5 rises, the pulling rod 806 will drive the cylinder 805 to rise and the cylinder 805 will contract. The cylinder 805 will send the gas back into the pneumatic telescopic rod 802 again through the connecting air pipe 807, causing the pneumatic telescopic rod 802 to extend. The pneumatic telescopic rod 802 will push the scraping head 803 to scrape the bottom of the pressing plate 5, preventing metal debris from adhering to the bottom of the pressing plate 5.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
