[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0026] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] The existing manual coating method not only reduces production efficiency, but also lacks coating uniformity and safety because the internal cavity of the mold needs to be coated. Therefore, in order to solve the above problems, this case proposes the following technical solutions:

[0028] Reference Figure 1 to Figure 4 As shown, a metal plate punching machine for processing lamp housings comprises: a base 5, a control panel 6 and a main unit 7 are respectively installed on the sides of the base 5, the control panel 6 and the main unit 7 are electrically connected, a bottom plate 1 is arranged on the upper surface of the base 5, a top plate 3 is installed on the top of the bottom plate 1, a slide bar of the top plate 3 is vertically fixed to the upper surface of the bottom plate 1, the slide bar surface of the top plate 3 also cooperates with the slide groove penetrating the upper template 2, a push rod 4 passes through the center hole of the top plate 3 and is connected to the surface of the upper template 2, the bottom plate 1 comprises a plate body 11, the plate body 11 cooperates with the slide bar of the top plate 3, a bottom mold 12 is installed in the middle of the plate body 11, and a groove is opened on the adjacent surface of the bottom mold 12, a sprayer 13 rotating along the movable axis of a driver 14 is arranged in the groove, and the sprayer 13 is connected to the base 5 through a feed pipe 15.

[0029] The main structure of the device includes a base 5, on the sides of which are respectively installed a control panel 6 for starting and a main machine 7 for controlling the push rod 4 to press down, and a stamping part is formed on the upper surface of the base 5 by a bottom plate 1, an upper template 2 and a top plate 3.

[0030] During stamping, the push rod 4 is pressed down. Specifically, the push rod 4 can adopt a hydraulic cylinder structure. The middle rod of the push rod 4 pushes the upper template 2, driving the mold on the surface of the upper template 2 to fit the mold on the surface of the bottom plate 1 to complete the stamping work.

[0031] In most existing processes, it is necessary to paint the bottom die 12 installed on the surface of the plate body 11 during stamping. However, the bottom die 12 is located in the middle of the stamping part, and the arm needs to be inserted into the machine during painting, which is highly dangerous in operation. In addition, it is also necessary to paint the upper die, that is, the die installed on the bottom surface of the upper die plate 2, and the coverage of the stamping oil is also relatively uneven. This application provides improvements to this.

[0032] A groove and a sprayer 13 are arranged on the surface of the plate 11 to accommodate the sprayer 13, so as to prevent the sprayer 13 from being squeezed and deformed when the upper template 2 is pressed down. The sprayer 13 is driven by a driver 14. Specifically, the driver 14 adopts a stepping motor, and the host 7 can better control its swing angle and swing speed to achieve better uniformity of spraying.

[0033] A driving shaft 132 cooperating with the driver 14 is installed on one side of the arm body 131, and the other side extends through the through hole of the plate body 11. The feed pipe 15 is connected to the inner tube 135 through the inner cavity of the arm body 131, and then the nozzle 133 is connected through the driver 14 to perform feed spraying. Specifically, the nozzle 133 uses high-pressure airflow to form the hydraulic oil into oil mist and spray it evenly into the molds of the bottom mold 12 and the upper mold 2.

[0034] The nozzle 133 is installed in the inner cavity of the arm body 131 through the adapter 134. The adapter 134 is a rotatable structure. When rotating, the nozzle 133 moves together, and the adapter 134 and the nozzle 133 are connected by threads, which is convenient for disassembly of the nozzle 133. During maintenance, it is only necessary to pull out the nozzle 133, and the nozzle 133 rotates around the adapter 134. Then, the nozzle 133 can be rotated to remove it and quickly replaced, which is more convenient in maintenance.

[0035] The specific working process of this device:

[0036] First, the driver 14 is started to work. The driver 14 drives the sprayer 13 to swing so that the nozzle 133 of the sprayer 13 is perpendicular to the surface of the plate 11. Then, the injector installed inside the base 5 is started. The injection structure drives the stamping oil to move by the high-pressure gas. The oil is transported to the inner tube 135 through the feed pipe 15, and then enters the outlet of the nozzle 133 connected to the adapter 134 through the inner tube 135. The flow rate of the hydraulic oil is adjusted by configuring the gas flow rate.

[0037] Then the push rod 4 slowly drives the upper template 2 to press down, moves to the vertical upper surface close to the sprayer 13 and stops, and the driver 14 drives the sprayer 13 to be in a swinging state, and sweeps and sprays the inner cavity of the mold through the upper and lower nozzles of the nozzle 133 respectively. When the spraying is completed, the driver 14 drives the sprayer 13 to reset and re-embed it into the inner groove of the plate body 11.

[0038] Finally, the metal plate is placed on the surface of the bottom mold 12, and the push rod 4 is controlled by the control panel 6 to fully press down.

[0039] The improved device drives the sprayer 13 through the driver 14 to oscillate and spray the stamping oil so that the surface of the bottom mold 12 can be evenly coated with a protective layer, and the sprayer 13 is located in the groove of the plate body 11 to avoid damage during the pressing process.

[0040] In order to make the maintenance of the sprayer 13 more convenient, the present application sets the nozzle 133 inside the sprayer 13 as a detachable structure. The nozzle 133 and the adapter 134 can be cleaned and replaced by rotating and disassembling, which improves the maintenance efficiency.

[0041] The above only describes the basic principles and preferred implementations of the present utility model. Those skilled in the art can make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of the present utility model.

[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
