Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate stamping, in particular to a stamping machine for producing aluminum single plates. Background Art

[0002] Aluminum veneer refers to a building decoration material that is processed by chroming and other treatments and then fluorocarbon spraying technology. The stamping process saves materials and energy compared to traditional mechanical processing, has high efficiency, does not require high technical skills of operators, and can produce products that cannot be achieved by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive. The stamping machine drives the flywheel through an electric motor, which ultimately drives the stamping head to move up and down, and cooperates with the mold to stamp the aluminum plate.

[0003] The stamping of some aluminum plates requires the use of a deeper mold. The aluminum plate after stamping is relatively thin, which is not conducive to using the ejection structure to push it out of the mold. Otherwise, it is easy to damage the aluminum part under the single point of resistance. Therefore, we propose a stamping machine for the production of aluminum veneer. Utility Model Content

[0004] The purpose of the utility model is to provide a punching machine for the production of aluminum veneers. After the mold is installed and fixed in the middle position of the support, the screw in the end of the connecting rod is screwed into the screw groove at the bottom of the iron plate to connect with it. After the aluminum plate is punched and formed by the punch and the mold, the punch is raised to a height and the iron plate is adsorbed through the aluminum plate by an electromagnet. The aluminum part is pushed out by the support of the iron plate. The contact area between the punch and the aluminum part is large, and the aluminum part will not be damaged by the single-point resistance effect, thereby solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a punching machine for the production of aluminum veneers, comprising a support, a punching machine and a mold, the punching machine is installed and fixed on the rear end of the surface of the support, a punch is installed at the bottom of the punching assembly of the punching machine, and a plurality of electromagnets are evenly embedded and fixed at the lower position inside the punch; the mold is installed and fixed on the surface of the support directly below the punch, an iron plate is slidably arranged inside the mold laterally, the bottom of the iron plate abuts against the surface of the support, and a screw groove is provided in the middle position of the bottom of the iron plate; a connecting rod is vertically slidably penetrated through the surface of the support directly below the screw groove, a butt plate is welded and fixed on the top of the connecting rod, the butt plate is placed in a support groove provided in the middle position of the support surface, a screw is vertically fixed at the middle position of the butt plate surface, the screw is screwed into the screw groove at the bottom of the iron plate, a pull ball is welded and fixed to the bottom end of the connecting rod, and a spring is provided on the outer ring sleeve of the connecting rod between the pull ball and the support.

[0006] By adopting the above technical solution, after the mold is installed in place, the screw at the top of the connecting rod is connected to the bottom of the iron plate, and the punch is used to cooperate with the mold and the iron plate inside it to stamp the aluminum plate. When the punch is raised, the electromagnet is energized to adsorb the iron plate to raise the height, and the aluminum part is pushed out to the outside. Due to the elastic force of the spring, the iron plate can no longer be adsorbed by the electromagnet, and is thus pulled back to the bottom of the mold by the spring and abuts against the surface of the support, and then the stamping work of the aluminum plate can continue.

[0007] Optionally, Hall sensors are installed on the surfaces of the support platforms on both sides of the support groove, and the Hall sensors are installed in the groove bodies opened on the surfaces of the support platforms and placed under the iron plate.

[0008] By adopting the above technical solution, when the iron plate is pulled back by the spring, the Hall sensor can detect the reset state of the iron plate, thereby preventing the iron plate from being stuck inside the mold without being discovered.

[0009] Optionally, four corners of the bottom of the support platform are vertically supported and fixed with supporting feet, and a plurality of supporting feet are provided.

[0010] By adopting the above technical solution, the support platform is supported to a certain height and stably supported by utilizing the support feet at the four corners of the bottom of the support platform.

[0011] Optionally, rubber pads are fitted and fixed to both side surfaces of the bottom of the iron plate, and both sides of the bottom of the iron plate are in contact with the surface of the support through the rubber pads.

[0012] By adopting the above technical solution, when the iron plate is pulled down by the spring and reset, the iron plate contacts the surface of the support platform when the spring provides a buffering effect.

[0013] Optionally, a penetrating rod hole is provided on the surface of the support platform at the connecting rod, and the connecting rod vertically penetrates the support platform through the rod hole.

[0014] By adopting the above technical solution, the connecting rod can slide through the top and bottom of the support platform through the rod hole.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The technical solution of the present application is to install and fix the mold in the middle position of the support, and then screw the screw in the end of the connecting rod into the screw groove at the bottom of the iron plate to connect with it. After the aluminum plate is stamped into shape by using the punch and the mold, the punch is raised and the iron plate is adsorbed through the aluminum plate by the electromagnet, and the aluminum part is pushed out by the support of the iron plate. The contact area between the punch and the aluminum part is large, which will not cause the aluminum part to be damaged by single-point resistance, and there is no need to set up an additional driving structure.

[0017] 2. The technical solution of the present application is to install a Hall sensor in the groove on the surface of the support inside the mold. When the iron plate is pulled by the spring to reset to the bottom of the mold, the Hall sensor can detect its reset effect and issue a reminder when the iron plate is not pulled to reset.

DETAILED DESCRIPTION

[0023] See also Figure 1-3 The utility model provides a technical solution: a punching machine for aluminum single plate production, including a support platform 1, a punching machine 2 and a mold 3. The four corners of the bottom of the support platform 1 are vertically supported and fixed with supporting legs 11. The supporting legs 11 are provided with multiple, and the lengths of the multiple supporting legs 11 are the same to achieve horizontal stable support for the support platform 1. The punching machine 2 is installed and fixed on the rear end of the surface of the support platform 1. A punch 21 is installed at the bottom of the punching assembly of the punching machine 2. When the punching machine 2 is working, it can drive the punch 21 to lower or raise its height.

[0024] The mold 3 is installed and fixed on the surface of the support 1 directly below the punch 21. An iron plate 31 is slidably placed inside the mold 3. The bottom of the iron plate 31 contacts the surface of the support 1. The aluminum plate is aligned and placed above the mold 3. When the punch 21 is lowered, it cooperates with the mold 3 and the iron plate 31 inside it to stamp the aluminum plate. The formed aluminum part is placed in the die groove of the mold 3. A plurality of electromagnets 211 are evenly embedded and fixed at the lower position inside the punch 21. Therefore, when the punch 21 is driven to rise, the electromagnet 211 is energized to generate magnetism and can absorb the iron plate 31 through the aluminum plate, so that the iron plate 31 is driven to rise in the mold 3, and then the aluminum part is supported and ejected from the mold 3 to the outside.

[0025] A screw groove 311 is provided at the middle position of the bottom of the iron plate 31, a support groove 121 is provided on the surface of the support platform 1 directly below the screw groove 311, a through rod hole 12 is vertically provided on the surface of the support platform 1 at the middle position of the support groove 121, a connecting rod 4 is vertically slidably penetrated through the support platform 1 through the rod hole 12, a support plate 43 is welded and fixed on the top of the connecting rod 4, and a screw rod 431 is vertically fixed at the middle position of the surface of the support plate 43, so that the screw rod 431 on the surface of the support plate 43 is screwed into the screw groove 311 to realize the connection between the connecting rod 4 and the iron plate 31, at this time, the support plate 43 is received in the support groove 121, and the connecting rod 4 A pulling ball 41 is welded and fixed at the bottom end, and a spring 42 is arranged on the outer ring of the connecting rod 4 between the pulling ball 41 and the support platform 1. When the iron plate 31 is adsorbed and raised upward, the spring 42 will be compressed and generate an elastic force acting downward. When the elastic force is too high, the iron plate 31 can no longer be adsorbed by the electromagnet 211 and is pulled down by the spring 42 to prevent the iron plate 31 from being pulled out of the mold 3. Rubber pads 32 are fixed to the two side surfaces of the bottom of the iron plate 31. When the iron plate 31 is pulled downward, it is finally supported by the rubber pads 32 against the surface of the support platform 1, thereby playing a buffering role.

[0026] Hall sensors 13 are installed on the surface of the support platform 1 on both sides of the support groove 121. The Hall sensors 13 are installed in the groove body opened on the surface of the support platform 1, and the Hall sensors 13 are located below the iron plate 31 on the inner side of the mold 3. When the iron plate 31 is pulled to reset, the Hall sensor 13 can detect whether the iron plate 31 is reset. The stamping work can be continued only after it is reset. Otherwise, it needs to be reset manually to avoid the situation where the iron plate 31 is stuck and not discovered when it is pulled to reset.

[0027] When in use, after the mold 3 is installed and fixed in the middle position of the surface of the support 1, the bottom screw groove 311 of the iron plate 31 is aligned with the middle position of the abutment plate 43 at the end of the connecting rod 4, and then the iron plate 31 is pressed down and the connecting rod 4 is pushed upward by pulling the ball 41 and driving it to rotate at the same time, so that the screw 431 is screwed into the screw groove 311 at the bottom of the iron plate 31, so as to realize the connection between the screw 431 and the iron plate 31, and at the same time, the Hall sensor 13 is located at the lower position of the iron plate 31, and the aluminum single plate is aligned and placed above the mold 3, and then the punching machine 2 is started to drive the punch 21 to lower the height, and the punch 21 cooperates with the iron plate 31 at the bottom of the mold 3 to stamp the aluminum single plate, and the formed aluminum part is placed in the mold 3, and when the punch 21 is driven to rise in height, the electromagnet 211 is energized and has magnetism, so that the iron plate 31 in the mold 3 can be adsorbed through the aluminum plate, and the iron plate 31 is pulled upward, and the iron plate 31 When it is pulled to a higher height, it can support and push the aluminum part out of the mold 3. When the iron plate 31 is pulled upward, it will also drive the connecting rod 4 to rise in height and use the pulling ball 41 to compress the spring 42. Until the punch 21 rises to a higher position, the elastic force generated by the compression of the spring 42 is larger, and the iron plate 31 is pulled downward so that the electromagnet 211 can no longer continue to absorb the iron plate 31, thereby preventing the iron plate 31 from being pulled out of the mold 3. The iron plate 31 is pulled to the bottom of the mold 3 under the resetting action of the spring 42 and is against the surface of the support 1. At this time, the aluminum part can be taken away, and the iron plate 31 has a buffering effect when it is pulled and reset by the spring 42 through the rubber pad 32 at its bottom. After the iron plate 31 is reset, the data can be detected by the Hall sensor 13, so that the stamping machine 2 can continue to perform the stamping work. Otherwise, it is judged that the iron plate 31 is in an unreset state, and it needs to be completely reset before the stamping process can continue.
