[0024] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Such as Figures 1 to 3As shown in the figure, a metal stamping and forming device according to an embodiment of the present utility model includes a stamping machine 1; a support frame 11 is fixedly connected to the top of the stamping machine 1; a cylinder 12 is fixedly connected to the top of the support frame 11; the output end of the cylinder 12 penetrates through the side wall of the support frame 11 and is fixedly connected to a punch 13; a mold groove 14 is formed in the top of the stamping machine 1; the mold groove 14 is arranged directly below the punch 13; a pair of grooves 15 are formed in the bottom of the mold groove 14; the grooves 15 are symmetrically arranged on the mold groove 14; a top spring 17 is fixedly connected to the bottom of the groove 15; the top end of the top spring 17 is fixedly connected to a top block 16; the top block 16 is located inside the groove 15 and is slidably connected to the groove 15. During operation, the metal part to be stamped and formed is placed above the mold groove 14, and then the control switch is turned on to drive the punch 13 to push downward by the cylinder 12, so that the punch 13 stamps the metal part into the mold groove 14 to form a pipe clamp part. At this time, under the stamping of the punch 13, the top block 16 located inside the mold groove 14 will slide downward and then enter the groove 15. When the metal part is stamped and formed, the punch 13 is controlled to reset upward. At this time, without the pressing of the punch 13, the top block 16 will move upward under the elastic action of the top spring 17, thereby pushing the formed pipe clamp that adheres to the inner side wall of the mold groove 14 upward due to stamping. When the punch 13 is reset, the formed pipe clamp will be separated from the mold groove 14 under the action of the top block 16 and be pushed out of the mold groove 14, facilitating the collection of the formed pipe clamp. By using the top block 16 to push the formed metal part out of the mold groove 14, the demolding is more convenient and fast, and the stamping processing speed is accelerated.

[0026] As Figures 1 to 4As shown in the figure, an electric push cylinder 2 is fixedly connected to the top of the stamping machine 1; a push block 21 is fixedly connected to the output end of the electric push cylinder 2; the push block 21 is arranged on the side of the mold groove 14; a blanking table 22 is opened at the top of the stamping machine 1; the blanking table 22 is inclined; a blanking groove 23 is opened at the bottom of the blanking table 22; a plurality of damping springs 24 are fixedly connected to the bottom of the blanking groove 23; an elastic plate 25 is fixedly connected to the top of the damping spring 24; the elastic plate 25 is located inside the blanking groove 23 and is slidably connected to the blanking groove 23. During operation, by providing a blanking groove 23 on the stamping machine 1, when the metal part is punched into a pipe clamp and is ejected from the inside of the mold groove 14 by the ejector block 16, by controlling the switch of the electric push cylinder 2, the electric push cylinder 2 drives the push block 21 to push forward, so that the push block 21 pushes the punched pipe clamp onto the blanking table 22, and the pipe clamp slides along the blanking table 22 onto the elastic plate 25. Under the elastic buffering of the elastic plate 25 and the damping spring 24, it falls smoothly onto the elastic plate 25, and then the pipe clamp that has fallen onto the elastic plate 25 is collected. By collecting the punched pipe clamp in the above manner, it can reduce the problem that the staff needs to reach into the stamping assembly to take out the forming assembly, reduce the occurrence of accidents such as bumps, and strengthen the protection of the safety of the working environment.

[0027] As Figures 2 to 5 shown, a pair of fixing plates 3 are fixedly connected to the inner side wall of the support frame 11; one end of the fixing plate 3 away from the support frame 11 is fixedly connected to the top of the stamping machine 1; the fixing plates 3 are symmetrically arranged on both sides of the mold groove 14; a guide rod 31 is slidably connected to the middle of the fixing plate 3; a clamping plate 32 is fixedly connected to the end of the guide rod 31 close to the mold groove 14; the top and bottom of the clamping plate 32 are respectively in contact with the side wall of the support frame 11 and the side wall of the stamping machine 1; a clamping spring 33 is fixedly connected between the side wall of the clamping plate 32 and the side wall of the fixing plate 3; the clamping spring 33 is sleeved on the guide rod 31. During operation, when punching a metal part, since the metal part needs to enter the mold groove 14 to change its shape, during the process of entering the mold groove 14, due to the impact of the punch 13, the metal part is likely to be misaligned, which reduces the punching quality. At this time, by providing a clamping plate 32 on the stamping machine 1, by placing the metal part to be punched above the mold groove 14, the clamping plates 32 on both sides of the mold groove 14 squeeze and fix both ends of the metal part. During the process of punching the metal part into the mold groove 14, a pair of clamping plates 32 are always squeezed and attached to both ends of the metal part under the elastic action of the clamping spring 33, making the movement of the metal part more stable, reducing the possibility of the metal part sliding on both sides during the process of entering the mold groove 14, improving the stability during the punching process of the metal part, and improving the production quality of the pipe clamp.

[0028] As Figure 5As shown, a graphite plate 4 is fixedly connected to the side wall of the fixed plate 3; the graphite plate 4 is sleeved on the guide rod 31; the graphite plate 4 and the guide rod 31 are in sliding fit. During operation, by sleeving the graphite plate 4 on the guide rod 31, when the guide rod 31 reciprocates, the graphite plate 4 and the surface of the guide rod 31 can be in frictional contact, so that the graphite plate 4 lubricates the guide rod 31, reducing the problem of jamming of the guide rod 31 after long-term use and improving the stability of the guide rod 31 during operation.

[0029] As Figure 5 and Figure 6 shown, a pair of limit plates 5 are symmetrically hinged to the side wall of the clamping plate 32; a return torsion spring is installed at the connection between the limit plate 5 and the clamping plate 32. During operation, by providing a pair of limit plates 5 on the clamping plate 32, when metal parts with different width dimensions are placed between the clamping plates 32, the limit plates 5 clamp the ends of the metal parts, and the torsion spring reduces the possibility of the metal parts sliding, increasing the stability during the stamping process of the metal parts.

[0030] As Figure 6 shown, a rubber pad 6 is fixedly connected to the side wall of the clamping plate 32; the rubber pad 6 is located on the side wall of the clamping plate 32 close to the mold groove 14. During operation, by providing the rubber pad 6 on the clamping plate 32, the friction force received when the metal part is fixed can be increased, improving the stability and safety during the processing of the metal part.

[0031] Working principle: Place the metal part to be stamped and formed above the mold groove 14, then turn on the control switch to drive the punch 13 to push downward by the cylinder 12, so that the punch 13 stamps the metal part into the mold groove 14 to form a pipe clamp. At this time, under the stamping of the punch 13, the top block 16 inside the mold groove 14 will slide downward and then enter the groove 15. When the metal part is stamped and formed, control the punch 13 to reset upward. At this time, without the pressing of the punch 13, the top block 16 will move upward under the elastic action of the ejecting spring 17, thereby pushing the formed pipe clamp that adheres to the inner side wall of the mold groove 14 upward due to stamping. When the punch 13 resets, the formed pipe clamp will be separated from the mold groove 14 under the action of the top block 16 and be pushed out of the mold groove 14, facilitating the collection of the formed pipe clamp. By making the top block 16 push the formed metal part out of the mold groove 14, the demolding is more convenient and fast, accelerating the stamping processing speed.

[0032] By providing a blanking groove 23 on the stamping machine 1, after the metal part is stamped into a pipe clamp and is ejected from the inside of the die groove 14 by the ejector block 16, by controlling the switch of the electric push cylinder 2, the electric push cylinder 2 drives the push block 21 to push forward, and then the push block 21 pushes the stamped pipe clamp onto the blanking table 22, so that the pipe clamp slides along the blanking table 22 onto the elastic plate 25. Under the elastic buffering of the elastic plate 25 and the damping spring 24, it drops smoothly onto the elastic plate 25, and then the pipe clamp that has dropped onto the elastic plate 25 is collected. By collecting the stamped pipe clamp in the above way, it can reduce the problem that the staff needs to reach into the inside of the stamping component to take out the forming component, reduce the occurrence of accidents such as bumps, and strengthen the protection of the safety of the working environment.

[0033] When stamping the metal part, since the metal part needs to enter the inside of the die groove 14 to change its shape, during the process of entering the inside of the die groove 14, due to the impact of the punch 13, the metal part is prone to dislocation, which in turn reduces the stamping quality. At this time, by providing clamping plates 32 on the stamping machine 1, by placing the metal part to be stamped above the die groove 14, the clamping plates 32 on both sides of the die groove 14 squeeze and fix both ends of the metal part. During the process of stamping the metal part into the inside of the die groove 14, a pair of clamping plates 32 are always squeezed and fitted against both ends of the metal part under the elastic action of the clamping springs 33, making the movement of the metal part more stable, reducing the possibility of the metal part sliding on both sides during the process of entering the inside of the die groove 14, improving the stability during the stamping process of the metal part, and improving the production quality of the pipe clamp.

[0034] By sleeving a graphite plate 4 on the guide rod 31, when the guide rod 31 reciprocates, the graphite plate 4 can be in frictional contact with the surface of the guide rod 31, and then the graphite plate 4 lubricates the guide rod 31, reducing the problem of jamming of the guide rod 31 during long-term use and improving the stability of the guide rod 31 during operation.

[0035] By providing a pair of limit plates 5 on the clamping plates 32, when placing metal parts of different width dimensions between the clamping plates 32, the limit plates 5 clamp the ends of the metal parts, reducing the possibility of the metal parts sliding under the action of the torsion springs and increasing the stability during the stamping process of the metal parts.

[0036] By providing rubber pads 6 on the clamping plates 32, the friction force received when the metal parts are fixed can be increased, improving the stability and safety during the processing of the metal parts.
