Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinet processing, in particular to a stamping device for distribution cabinet processing. Background Technique

[0002] During the production and processing of the distribution cabinet shell, a stamping device is required for the square shell sheet metal part with flanging. Its function is to form the metal sheet through a mold and pressure. Its main structures include a frame, a slider, a mold, a transmission mechanism and a hydraulic system. The frame, as the main part, supports and fixes other components to ensure the stability and rigidity of the equipment; the slider realizes reciprocating up and down movement through the transmission mechanism and is the main executing component of the stamping action; the mold is designed according to the requirements of the processed part to be able to complete the punching and flanging shapes. When the slider presses down, the mold applies pressure to the metal sheet to complete processing operations such as punching and flanging. At the present stage, after the stamping and flanging actions are completed on the square sheet material, the formed square shell sheet metal part stays in the lower stamping mold. Some lower molds are provided with an ejecting mechanism to separate the sheet metal part from the mold cavity, but the sheet metal part is still located in the lower mold. At this time, the staff needs to reach into the space between the lower mold and the upper mold and manually take it out from the lower mold. In the case of mass production, the formed sheet metal part is relatively heavy. Waiting for the staff to manually take out the sheet metal part will lead to an extended production cycle and affect the efficiency of the entire production line. Content of the Utility Model

[0003] The purpose of the utility model is to provide a stamping device for distribution cabinet processing. A Y-axis gear and rack moving mechanism is added between the main frame and the sub-frame. Two electromagnets are installed at the movable end of the Y-axis gear and rack moving mechanism. After the upper and lower molds are separated, the electromagnets move above the lower mold and magnetically attract the formed sheet metal part, so as to use the electromagnets and the Y-axis gear and rack moving mechanism to move out the formed workpiece, so as to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A stamping device for distribution cabinet processing, including a main frame and a sub-frame arranged on one side of the main frame.

Specific implementation manners

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A stamping device for processing power distribution cabinets, including a main frame 1 and a sub-frame 2 arranged on one side of the main frame 1. The top ends of the main frame 1 and the sub-frame 2 are fixed with a truss 3, and a hydraulic cylinder 5 is installed at the top end of the truss 3. The top end of the piston rod of the hydraulic cylinder 5 is fixed with an upper template 4. Both sides of the bottom end of the upper template 4 are installed with upper stamping dies 7. One end of the surface of the upper stamping die 7 is fixed with a return-shaped pressing edge plate 701. Lower stamping dies 6 are fixed at one ends inside the main frame 1 and the sub-frame 2. A stamping groove 603 for the upper stamping die 7 to enter is arranged at the top end of the lower stamping die 6. The hydraulic cylinder 5 drives the upper template 4 and the two upper stamping dies 7 to move downward synchronously. During the process that the upper stamping die 7 moves downward and is combined with the lower stamping die 6, the square sheet material sinks into the stamping groove 603, and the return-shaped pressing edge plate 701 makes a flanging at the edge position of the square sheet material. During this process, the hydraulic cylinder 5 continuously provides hydraulic downward pressure;

[0019] A Y-axis rack-and-pinion moving mechanism 11 is arranged between the relative outer walls between the main frame 1 and the auxiliary frame 2. Two symmetrical electromagnets 9 are installed at the movable end of the Y-axis rack-and-pinion moving mechanism 11. A PLC control panel 8 is installed on the outer wall on one side of the main frame 1. The output end of the PLC control panel 8 is electrically connected to the hydraulic cylinder 5, the Y-axis rack-and-pinion moving mechanism 11, and the input end of the electromagnet 9. The Y-axis rack-and-pinion moving mechanism 11 drives the electromagnet 9 to move in the Y-axis direction, that is, the electromagnet 9 generates magnetic force and adsorbs the square shell sheet metal, and the Y-axis rack-and-pinion moving mechanism 11 sends the adsorbed square shell sheet metal to the outside of the main frame 1 and the auxiliary frame 2.

[0020] A guide plate 101 is fixed on the outer wall of the main frame 1 and the auxiliary frame 2 on one side away from each other. One end of the electromagnet 9 extends to the inside of the guide plate 101 and slides with the guide plate 101. A rectangular slide groove for sliding the power supply magnet 9 is provided on the outer wall of one side of the guide plate 101. The cooperation between the rectangular slide groove and the electromagnet 9 can improve the stability of the electromagnet 9 during the sliding process and reduce the instability caused by swinging or offset.

[0021] Rectangular sinking cavities 601 are provided on both sides of the top of the lower stamping die 6. A rectangular push plate 10 is slidably installed inside the rectangular sinking cavity 601. The top of the rectangular push plate 10 penetrates to the outside of the lower stamping die 6. A number of coil springs 602 are installed at equal intervals at the bottom of the rectangular sinking cavity 601. The top of the coil spring 602 is fixedly connected to the bottom of the rectangular push plate 10. After the upper stamping die 7 and the lower stamping die 6 are closed, the rectangular push plate 10 is completely sunk into the rectangular sinking cavity 601. When the stamping action is completed, the coil spring 602 gradually recovers from the compressed state to the initial state, that is, the rectangular push plate 10 supports the flange of the sheet metal and pushes the sheet metal upward, so that the bottom surface of the sheet metal is separated from the bottom wall of the stamping groove 603, so as to facilitate the subsequent magnetic attraction of the sheet metal.

[0022] The rectangular push plate 10 is made of a hard plastic material, and the rectangular push plate 10 made of hard plastic material will not be magnetically attracted by the electromagnet 9;

[0023] The Y-axis gear-rack moving mechanism 11 includes two supporting plates 1101 fixed between the opposite outer walls of the main frame 1 and the sub-frame 2, and a convex connecting arm 1102 slidably mounted at the top ends of the two supporting plates 1101. One end of the electromagnet 9 is fixedly connected to the outer wall of one side of the convex connecting arm 1102. A servo motor 1103 is installed on one side of the bottom end of one of the supporting plates 1101. The output end of the servo motor 1103 is installed with a driving gear 1105. An inclined rack 1104 is fixed on the outer wall of the convex connecting arm 1102 close to the servo motor 1103. The inclined rack 1104 and the driving gear 1105 are meshed with each other. When moving the workpiece out of the lower stamping die 6, the rotational power of the servo motor 1103 is transmitted to the driving gear 1105, and then the driving gear 1105 drives the inclined rack 1104 and the convex connecting arm 1102 to perform Y-direction sliding, that is, the electromagnet 9 moves together. At this time, the electromagnet 9 and the sheet metal part held by magnetic attraction are moved out of the lower stamping die 6 by the Y-axis gear-rack moving mechanism 11, so as to replace manual blanking operation;

[0024] Dovetail slide sleeves are fixed on both sides of the top end of the supporting plate 1101. A guide rail slidably matched with the dovetail slide sleeve is installed at the bottom end of the convex connecting arm 1102. The cooperation between the dovetail slide sleeve and the guide rail can improve the stability of the connecting components, make the connection between the supporting plate 1101 and the convex connecting arm 1102 more firm, and is not easy to loosen or swing.

[0025] When the embodiment of the present application is in use, first, the staff places the square sheet metal of the distribution cabinet to be stamped on the top of the lower stamping die 6 and adjusts the square sheet metal to the correct position. Subsequently, the staff starts the hydraulic cylinder 5 to work through the PLC control panel 8. Then, the hydraulic cylinder 5 drives the upper template 4 and the two upper stamping dies 7 to move downward synchronously. During the process that the upper stamping die 7 moves downward and closes with the lower stamping die 6, the square sheet metal sinks into the stamping groove 603, and the loop-shaped edge pressing plate 701 causes the edge position of the square sheet metal to form a flanging. During this process, the hydraulic cylinder 5 continuously provides hydraulic downward pressure. After the lower stamping die 6 and the upper stamping die 7 complete one stamping, the upper stamping die 7 and the upper template 4 are driven by the piston rod of the hydraulic cylinder 5 to move upward and separate from the metal sheet, preparing for the next stamping. At this time, the formed square shell sheet metal part with flanging is on the top of the lower stamping die 6. The staff starts the Y-axis rack and pinion moving mechanism 11 and the electromagnet 9 to work through the PLC control panel 8. At this time, the electromagnet 9 generates a magnetic force, which can attract the square shell sheet metal part. The Y-axis rack and pinion moving mechanism 11 drives the electromagnet 9 to move in the Y-axis direction, that is, the electromagnet 9 generates a magnetic force and adsorbs the square shell sheet metal part, and the Y-axis rack and pinion moving mechanism 11 sends the adsorbed square shell sheet metal part out of the main frame 1 and the sub-frame 2. At this time, the staff can connect the square shell sheet metal part behind the main frame 1 and the sub-frame 2, thereby completing the rapid blanking operation of the workpiece. After the stamping process of this stamping device is completed, the electromagnet 9 moves above the lower die and magnetically adsorbs the formed sheet metal part, and the Y-axis rack and pinion moving mechanism 11 is used to move the formed workpiece out, realizing automatic material discharging, reducing manual intervention, and at the same time reducing the safety risk of manual operation, and can effectively improve the production efficiency of the device.
