DETAILED DESCRIPTION

[0029] See attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of accelerating the falling of residues in the present application is:

[0030] A metal pressing device, comprising a base 20 with a screw rod 21 connected to the rear side for vertical rotation, a crossbeam 19 connected to the screw rod 21 for sliding contact with the rear side of the base 20, a rotating shaft 18 connected to the crossbeam 19 for horizontal rotation, threads with opposite rotation directions are provided on both sides of the rotating shaft 18, and clamping arms 15 are connected to both sides of the rotating shaft 18; the front end of the clamping arm 15 is rotatably connected to a rotating tube 03, the inner end of the rotating tube 03 is fixedly connected to a square tube 01, the inner end of the square tube 01 is fixedly connected to a clamping plate 02, and the outer end of the rotating tube 03 is fixedly connected to a gear ring A 04, the outer side of the clamping arm 15 is rotatably connected to a gear A16 meshing with the gear ring A04, the outer side of the rotating tube 03 is fixedly connected to a petal ring 06, the outer side of the clamping arm 15 is slidably connected to a slide bar 17 in contact with the petal ring 06, and a spring is fixedly connected between the slide bar 17 and the clamping arm 15; after the metal raw material is set up and a single pressing is performed, the rotating shaft 18 is driven to rotate by a motor, so that the rotating shaft 18 drives the two clamping arms 15 to approach each other, so that the two clamping plates 02 approach the metal raw material from the left and right ends and complete the clamping, and then through Another motor drives the screw rod 21 to rotate, so that the screw rod 21 drives the crossbeam 19 to rise, thereby raising the height of the clamped metal raw material, and then the motor drives the gear A16 to rotate, so that the gear A16 engages the gear ring A04 to drive the rotating tube 03 to rotate, so that the rotating tube 03 drives the clamping plate 02 to rotate, so as to achieve the effect of flipping the metal raw material. After the flipping is completed, the operation is reversed, and the metal raw material is placed back, and subsequent pressing can be carried out. Repeating the above operation can realize the flipping and pressing process of the metal raw material; and when flipping the metal raw material, the petal ring 06 can be made to continuously contact the end of the slide rod 17 when following the rotation of the rotating tube 03, so as to utilize the continuous collision and contact between the two to generate vibration, and transmit the vibration to the metal raw material, so that when the metal raw material vibrates, the residue generated on the surface due to pressing is vibrated off, so that the surface of the metal raw material is kept clean during pressing, and the residue during the pressing process is prevented from affecting the surface roughness and effect of the metal raw material after pressing.

[0031] See attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of scraping the residue of the present application is:

[0032] The base 20 is buckled with a pad 23, and a rear bar 27 is slidably connected to the rear side of the pad 23. A spring is fixedly connected between the rear bar 27 and the pad 23, and a scraper 26 is fixedly connected to the front end of the rear bar 27 and slides on the upper surface of the pad 23. The metal raw material is mounted on the pad 23, and the residue generated during the pressing process will fall on the pad 23. The rear bar 27 can be pushed forward to drive the scraper 26 to move forward on the pad 23, and the residue on the pad 23 can be pushed to the front until it falls from the front of the pad 23, thereby realizing the cleaning process of the pad 23, and avoiding the residue staying on the pad 23 to contact with the metal raw material and affect the pressing effect.

[0033] Furthermore, an inclined frame 28 is fixedly connected to the lower middle end of the cross beam 19, and the inclined surface of the inclined frame 28 contacts the rear end of the rear bar 27. When the cross beam 19 rises and the metal raw material is turned over, the inclined surface of the inclined frame 28 can push the rear bar 27 forward to complete the process of cleaning the pad 23. When the inclined frame 28 descends, the rear bar 27 can be reset by a spring.

The motor 24 can drive the circular plate 25 to rotate, and the upper surface of the circular plate 25 is flush with the upper surface of the pad 23. As the pressing proceeds, the circular plate 25 can be driven to rotate by the motor 24, so that the metal raw material placed on the circular plate 25 rotates with the circular plate 25, thereby realizing the direction adjustment of the metal raw material.

A transverse groove 30 is fixedly connected to the front end of the vertical plate 29, and a plurality of springs are fixedly connected to the inner wall of the rear end of the transverse groove 30. A scraper 31 is in sliding contact with the transverse groove 30, and the scraper 31 slides back and forth in the transverse groove 30. After the metal raw material is set up, the rear end of the metal raw material is in contact with the front end of the scraper 26, and the scraper 26 can be used to scrape the residue attached to the surface of the metal raw material when the metal raw material is turned over, thereby improving the cleaning ability and effect of the residue. The plurality of springs on the inner wall of the rear end of the transverse groove 30 can support the scraper 31, so that the front end of the scraper 31 is always in contact with the metal raw material, thereby ensuring the residue cleaning effect on the surface of the metal raw material.

[0040] Furthermore, a threaded tube 10 is rotatably connected to the middle part of the sliding frame 07, a threaded sleeve 11 is connected to the threaded tube 10, connecting rods 12 are rotatably connected to the front and rear ends of the threaded sleeve 11, the two connecting rods 12 are rotatably connected to the two auxiliary blocks 09 respectively, a toothed ring B13 is fixedly connected to the outer end of the threaded tube 10, and a gear B14 meshing with the toothed ring B13 is rotatably connected to the outer end of the sliding frame 07; the threaded tube 10 can be rotated by using a motor to drive the gear B14 to mesh with the toothed ring B13, so that the threaded sleeve 11 can move on the threaded tube 10, and the threaded sleeve 11 can drive the two connecting rods 12 to realize that the two connecting rods 12 drive the two auxiliary blocks 09 to move on the two side channels 08, thereby changing the spacing between the two auxiliary blocks 09, and the clamping range can be adjusted according to the size of the metal raw material, thereby improving the stabilization effect on the metal raw material.

[0041] See attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of improving the adaptability of the present application is:

[0042] The sliding frame 07 is in sliding contact with the square tube 01, and a spring is fixedly connected between the outer end of the sliding frame 07 and the rotating tube 03. The length of the inner end surface of the two auxiliary blocks 09 from the center of the cross beam 19 is less than the length of the inner end surface of the clamping plate 02 from the center of the cross beam 19; when clamping the metal raw material, the two auxiliary blocks 09 first contact the metal raw material, and then as the square tube 01 continues to move, the clamping plate 02 can continue to approach the metal raw material to achieve clamping, and the two auxiliary blocks 09 at this time will drive the sliding frame 07 to slide on the square tube 01, and the spring can support the sliding frame 07 so that the two auxiliary blocks 09 are always in contact with the metal raw material, and can move accordingly according to the height difference between the position of the metal raw material contacted by the clamping plate 02 and the position of the metal raw material contacted by the two auxiliary blocks 09, so as to achieve the metal raw material with irregular surface at the clamping position.

The cavity, square tube 01, rotating tube 03 and rotating port 05 are connected in sequence. By connecting the pipeline to the rotating port 05, cold water can be passed into the cavity, square tube 01 and rotating tube 03. The cold water is used to lower the overall temperature to avoid softening when in contact with high-temperature metal raw materials, thereby improving the deformation resistance.
