Description

Technical Field

[0001] The present invention relates to the field of stamping technology, in particular to a metal manufacturing stamping machine for fire fighting. Background Art

[0002] Metal manufacturing punching machine is a kind of mechanical equipment widely used in the metal processing industry. It is mainly used to punch metal sheets into molds to form the required parts or shapes. The punching machine is mainly composed of a mechanical bed, a workbench, a slider, a connecting rod, a cam mechanism and a mold. During the working process, the metal sheet is first placed on the workbench and accurately positioned by the positioning system. Then, the control system starts to drive the slider and the connecting rod to reciprocate. When the slider moves downward, the mold exerts pressure on the metal sheet to deform it. Finally, the slider is lifted to complete a punching process.

[0003] A patent application with application number CN202222153704.5 discloses a stamping machine for metal manufacturing, which belongs to the field of metal manufacturing technology, and includes a stamping machine base, a hydraulic rod is fixedly installed on the top of the stamping machine base, and a stamping plate is fixedly installed at the movable end of the hydraulic rod at an internal position of the stamping machine base, a bottom plate is installed at the bottom end of the stamping plate inside the stamping machine base, and a multi-faceted protective mechanism is fixedly installed on one end face of the stamping plate.

[0004] In current industrial production, stamping machines are a common processing equipment. However, when the existing stamping machines are stamping plates, if the plates are not fixed stably, the plates cannot maintain a stable state under the strong pressure of stamping.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example 1: See Figure 1-Figure 4The present invention provides a technical solution: a metal manufacturing punching machine for fire fighting, comprising a bottom plate 1, a punching machine 2 is fixedly connected to the top of the bottom plate 1, a workbench 9 is fixedly connected to the inner wall of the middle end of the punching machine 2, a motor 3 is fixedly connected to the top of the punching machine 2, a telescopic rod 4 is fixedly connected to the output end of the motor 3, and a punching head 6 is fixedly connected to the bottom of the telescopic rod 4, which preferably includes: The pressing mechanism 5 includes a top plate 501, the inner wall of the top plate 501 is fixedly connected to the outer wall of the telescopic rod 4, two groups of rectangular blocks 502 are fixedly connected to the left side of the bottom of the top plate 501, the middle ends of the bottoms of the two groups of rectangular blocks 502 are fixedly connected to bent rods 503, the two groups of bent rods 503 respectively penetrate the sliding blocks 504 and are fixedly connected thereto, the two groups of sliding blocks 504 are fixedly connected to the sides close to each other with cross bars 505, the outer walls of the cross bars 505 are provided with two groups of first connecting rods 506, the inner walls of the two groups of first connecting rods 506 are fixedly connected with first springs 508, by providing the first springs 508, when the plate is stamped, the first springs 508 can absorb the impact force borne by the plate. In this way, during the stamping process, the plate will not be fixed too tightly, and the stamping force can be controlled in time and effectively. The tops of the two groups of first springs 508 are respectively fixedly connected with pressing rods 507, and the outer walls of the pressing rods 507 are fixedly connected with two groups of fixing rings 512, and the bottoms of the two groups of fixing rings 512 are fixedly connected with pressing blocks 509, and sliding rods 511 are arranged on the inner walls of the left and right sides of the pressing blocks 509, and the positive and negative ends of the two groups of sliding rods 511 are fixedly connected to the inner wall of the pressing block 509, and the outer walls of the two groups of sliding rods 511 are fixedly connected with clamps 510, and the pressing mechanism 5 is arranged so that the two groups are symmetrically arranged with the middle part of the workbench 9 as the center.

[0025] The working principle of this embodiment is as follows: when the staff needs to punch the sheet metal, first put the sheet metal onto the workbench 9, then start the motor 3, then the motor 3 drives the telescopic rod 4 to press down, and when the telescopic rod 4 is pressed down, it drives the top plate 501 to move down, and when the top plate 501 moves down, it drives the rectangular block 502 to move down, and when the rectangular block 502 moves down, it drives the bending rod 503 to move down synchronously, so that the bending rod 503 drives the sliding block 504 to move down, so that when the sliding block 504 slides downward, it drives the first connecting rod 506 to move down, and at this time, the first connecting rod 506 drives the pressing rod 507 to move downward. The pressing rod 507 moves downward synchronously, so that when the pressing rod 507 moves downward, it will drive the fixing ring 512 to move downward, so that when the fixing ring 512 moves downward, the pressing block 509 will fit with the top of the plate and press it to fix it. At this time, the punching head 6 will contact the plate and punch the plate. At this time, the plate will be subjected to impact force, which will be absorbed by the pressing block 509 and then transmitted to the pressing rod 507 through the fixing ring 512. The pressing rod 507 then transmits the impact force to the first spring 508, causing it to contract and then release to discharge the punching force.

[0026] Example 2: Please refer to Figure 5-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: a clamping mechanism 7, the clamping mechanism 7 includes two groups of fixed blocks 701, the bottoms of the two groups of fixed blocks 701 are fixedly connected to the top of the workbench 9, the sides of the two groups of fixed blocks 701 close to each other are respectively fixedly connected with curved rods 702, the curved rods 702 are rotatably connected with rotating blocks 704 through a rotating shaft, and two groups of second moving rods 705 are arranged on the inner wall of the rotating block 704, the two groups of second moving rods 705 are fixedly connected to the rotating block 704 on both sides, and the outer walls of the two groups of second moving rods 705 are fixedly connected with first moving blocks 706, and the sides of the rotating blocks 704 away from the second moving rods 705 are rotatably connected with clamping plates 708 through a rotating shaft, and the clamping plates 708 are arranged to fix the plates in the non-stamping area, and through the fixing effect of the clamping plates 708, when the plates are impacted, part of the impact force can be transmitted to the clamping plates 708. At the same time, the clamping plate 708 fixes the plate in both directions, which can effectively limit the position of the plate. The inner walls of the two groups of clamping plates 708 are fixedly connected with the first moving rod 703, the outer walls of the two groups of first moving rods 703 are fixedly connected with the second moving blocks 709, the tops of the two groups of second moving blocks 709 are fixedly connected with the second springs 707, and the sides of the two groups of second springs 707 away from the second moving blocks 709 are fixedly connected to the first moving blocks 706. The clamping mechanism 7 is set into two groups, and they are symmetrically arranged with the middle of the workbench 9 as the center.

[0027] The working principle of this embodiment is as follows: when the plate is placed on the workbench 9, the staff rotates the bending rod 702 to fit it against the plate. After the bending rod 702 completes the rotation, the rotating block 704 is rotated for the second time, causing the clamping plate 708 to fit with the top of the plate through the rotation of the rotating shaft. When the clamping plate 708 rotates, it will drive the first moving rod 703 to move, so that the first moving rod 703 drives the second moving block 709 to move, causing the second moving block 709 to move and compress the second spring 707. At this time, when the plate is subjected to the punching pressure, the clamping plate 708 will transmit it to the first moving rod 703 through the clamping plate 708, and then transmitted to the second moving block 709 by the first moving rod 703, so that the second spring 707 begins to absorb the punching pressure, thereby bending again, so that the punching pressure will be relieved.

[0028] Example 3: Please refer to Figure 8-Figure 9 On the basis of the first and second embodiments, the present invention provides a technical solution: a fixing mechanism 8, the fixing mechanism 8 comprises two groups of bending rods 801, the left sides of the two groups of bending rods 801 are fixedly connected with a base 802, the sides of the two groups of bases 802 away from the bending rods 801 are rotatably connected with a rotating plate 804 through a rotating shaft, and the sides of the two groups of rotating plates 804 away from the bending rods 801 are rotatably provided with a wrapping block 803, by setting the wrapping block 803, the wrapping block 803 can be used to adjust the angle of the second connecting rod 805, and at the same time, since the rotating plate 804 adopts a circular design, after the rotation is completed, the wrapping block 803 can move forward a certain distance, so that the fixed column 807 can limit the position of the rotating block 704, and the sides of the two groups of wrapping blocks 803 away from the rotating plate 804 are fixedly connected with the second connecting rod 805, the two sets of second connecting rods 805 are fixedly connected with arc blocks 806 on the side away from the rotating plate 804. By setting the arc blocks 806, the function is to limit the angle of the rotating block 704. When the fixing column 807 on the arc block 806 contacts the hole at the tail of the rotating block 704, the rotating block 704 is fixed by the bolt connection of the two sets of contact plates 808. In this way, the rotating block 704 will not rotate again after completing the rotation. The two sets of arc blocks 806 are fixedly connected with the contact plate 808 on the side away from the second connecting rod 805. The two sets of contact plates 808 are connected by bolts on the sides close to each other. The two sets of arc blocks 806 are fixedly connected with the fixing columns 807 on the side away from the second connecting rod 805. The fixing mechanism 8 is set in two groups, and they are symmetrically arranged with the middle of the workbench 9 as the center.

[0029] The working principle of this embodiment is as follows: after the staff rotates the rotating block 704, the staff will rotate the rotating plate 804, and then continue to rotate the wrapping block 803 to rotate the angle, so that the wrapping block 803 will drive the second connecting rod 805 to rotate, so that the second connecting rod 805 drives the arc block 806 to rotate, so that after the angle of the arc block 806 is adjusted, it will be pushed, and the fixing column 807 on the arc block 806 will be combined with the hole at the tail of the rotating block 704 to fix it, and the contact plates 808 on both sides will fit each other, and then fixed by bolts to complete the work.
