Description

Technical Field

[0001] The utility model relates to the technical field of punching devices for metal castings, in particular to a punching device for metal castings. Background Art

[0002] A punching device for metal castings is a special equipment for processing holes in metal castings, including a power system, a punching die, a guiding and positioning system, and a control system. In practical applications, the punching device for metal castings is widely used in fields such as automobile manufacturing, machining, and construction.

[0003] Most of the existing punching devices for metal castings only set up a set of power system, punching die, guiding and positioning system, and control system. Therefore, only one casting can be set at a time. For the processing of a large number of castings, the processing of castings one by one greatly reduces the punching efficiency of the castings. For example, in the field of automobile parts manufacturing, for each installation hole of the engine block, it is necessary to re-clamp, position, and punch operations, which not only consumes a lot of time but also increases the labor intensity of the operators and cannot meet the needs of large-scale production. Another example is that in the production of building steel structures, for a large number of steel beam connectors that need to be punched, the mode of processing each single casting one by one seriously slows down the production progress and affects the project delivery time. Therefore, it is necessary to design a punching device for metal castings to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a punching device for metal castings to solve the deficiencies existing in the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A punching device for metal castings includes an installation disk and a plurality of fixing frames. A rotating disk is rotatably connected to the side wall of the installation disk. A plurality of mounting frames are provided on the installation disk. A punching motor is installed on the mounting frame through a hydraulic cylinder. A positioning mechanism for positioning the casting is provided on the rotating disk. The positioning mechanism includes two positioning blocks arranged on the rotating disk. A positioning frame is arranged inside the two positioning blocks. Positioning bolts are arranged on multiple side walls of the positioning frame. An electric push rod is provided on the fixing frame. Two electromagnets are installed at the output end of the electric push rod through a moving frame. A guiding mechanism for guiding out debris is arranged on the side wall of the mounting frame.

[0007] Preferably, the guiding mechanism includes a guiding material shell fixedly connected to the side wall of the mounting frame. The lower end of the guiding material shell penetrates through the lower end of the installation disk.

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-4 , a metal casting punching device, including a mounting disc 1 and a plurality of fixing brackets 7. The side wall of the mounting disc 1 is rotatably connected with a rotating disc 4. A plurality of mounting brackets 2 are arranged on the mounting disc 1. A punching motor 3 is installed on the mounting bracket 2 through a hydraulic cylinder. A positioning mechanism for positioning the casting is arranged on the rotating disc 4. The positioning mechanism includes two positioning blocks 14 arranged on the rotating disc 4. A positioning frame 8 is arranged inside the two positioning blocks 14. Positioning bolts 9 are arranged on multiple side walls of the positioning frame 8. An electric push rod 6 is arranged on the fixing bracket 7. The output end of the electric push rod 6 is installed with two electromagnets through a moving bracket 5. The electromagnets are shown in the figure. The punching motor 3 (including the motor, drill bit, and drill bit mounting seat) is a prior art in the field of casting punching, so no more details will be described.

[0024] A guiding mechanism for guiding out debris is arranged on the side wall of the mounting bracket 2. The guiding mechanism includes a material guiding housing 10 fixedly connected to the side wall of the mounting bracket 2. The lower end of the material guiding housing 10 penetrates through the lower end of the mounting disc 1.

[0025] In the present invention, a driving motor 16 is arranged on one of the fixing brackets 7. The output shaft of the driving motor 16 is fixedly connected with a gear 17. A gear ring 18 is arranged on the inner wall of the rotating disc 4, so that the rotating disc 4 does not need to be rotated manually, thereby improving the practicability of the device.

[0026] In the present invention, two positioning blocks 14 are fixedly connected to the inner bottom of the mounting bracket 2. After the positioning frame 8 is pushed to the side wall of the positioning block 14, the center of the positioning frame 8 is directly below the center of the punching motor 3 to accurately position the positioning frame 8. A knob is fixedly connected to the side wall of the positioning bolt 9.

[0027] In the present invention, an air compressor 15 is fixedly connected to the lower end of the fixing bracket 7. The air outlet end of the air compressor 15 is communicated with an air jet gun 11. The air jet gun 11 includes an air outlet nozzle and a pipeline. The pipeline is a sufficiently long flexible hose, so that when cleaning the waste chips, it is not necessary to manually use tools such as brushes to sweep the waste chips into the material guiding housing 10.

[0028] In the present utility model, a placement rack 12 is provided on the side wall of the mounting rack 2. The placement rack 12 is made of metal, and a placement groove is formed at its upper end. The pipeline of the air jet gun 11 is placed into the placement groove, so that the placement rack 12 holds the air jet gun 11 in place, preventing it from being placed randomly. A plurality of mounting racks 2 are arranged at equal intervals.

[0029] During use, an operator is arranged on one side of the rotating disk 4 to load the casting. The rotating disk 4 is rotated to make the nearest positioning frame 8 rotate to the loading position, and the casting is placed into the positioning frame 8. A plurality of positioning bolts 9 position the casting. The rotating disk 4 is rotated to move the next positioning frame 8 to the loading position. When all the positioning frames 8 are filled with castings and rotated to the front of the adjacent mounting rack 2, as shown in the figure, a plurality of electric push rods 6 are activated. The moving frame 5 moves towards the adjacent positioning frame 8, the electromagnet is powered on to adsorb the positioning frame 8, and the positioning frame 8 is pushed under the punching motor 3 of the mounting rack 2. The hydraulic cylinder and the punching motor 3 are activated to punch the casting. After punching, the output end of the electric push rod 6 contracts, and the positioning frame 8 returns to the rotating disk 4 again. By rotating the rotating disk 4, the loading and unloading of the casting can be carried out.

[0030] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and practical concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
