Description

Technical Field

[0001] The utility model relates to the field of punching devices, in particular to a punching device for a hand-plate model. Background Art

[0002] A prototype model is one or more functional samples made based on the product appearance drawings or structural drawings before making a mold. They are used to check the rationality of the appearance or structure, such as mobile phone shells, tablet shells and other terminal prototype models. Usually, products that have just been developed or designed need to be prototyped. Prototypes are the most direct and effective way to find out the defects, deficiencies, and drawbacks of the designed products, so as to make targeted improvements to the defects. Usually, small-batch trial production is also required to find out the deficiencies in the batch and improve them.

[0003] During the punching process, the shell to be punched needs to be placed inside the mold, and then the shell is punched through the punch. However, when the traditional punching device is working, when the punching of other shells in the mold is completed, the inner shell needs to be taken out and then replaced with a new shell. The operation process is performed manually or by a robotic arm, which greatly affects the overall punching efficiency. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, a punching device for a hand-plate model comprises a conveying frame 1, two transmission rods 2 are movably installed on the inner side of the conveying frame 1, a first motor 3 is installed on the surface of the conveying frame 1, the first motor 3 is used to drive one of the transmission rods 2 to rotate, a plurality of conveyor belts 4 are arranged between the two transmission rods 2, the width of the conveyor belt 4 is relatively narrow, in this embodiment, there are two conveyor belts 4, a plurality of limit plates 5 are equidistantly arranged on the surfaces of the plurality of conveyor belts 4, the distance between two adjacent limit plates 5 is the width distance of the outer shell, a die 6 is installed inside the conveying frame 1 below the conveyor belt 4, the die 6 is located between the two conveyor belts 4 or on the outside, a movable punch 7 is arranged on the surface of the conveying frame 1 through a mounting frame, and the punch 7 is located directly above the die 6.

[0025] When in use, the outer shell that needs to be punched is placed between two limit plates 5, and the top and bottom of the outer shell are against the two sides inside the conveyor frame 1. When the conveyor belt 4 drives the outer shell to move to the position of the die 6, the punch 7 moves downward to punch. The process can be positioned by a position sensor to ensure the accuracy of the punching. The waste generated by the punching can be removed through external settings to facilitate the next punching. The entire process does not require repeated taking out and putting in of the outer shell, which greatly reduces the production time and improves the efficiency of punching.

[0026] A plurality of support plates 8 are fixedly installed inside the conveyor frame 1. The plurality of support plates 8 are equidistantly arranged. The support plates 8 are located on the lower surface of the upper layer of the conveyor belt 4. The support plates 8 provide support force for the conveyor belt 4 to prevent the collecting shell from bending the conveyor belt 4.

[0027] Transverse grooves 9 are provided on both sides of the interior of the conveying frame 1, and two rotating shafts 10 are movably installed inside the transverse grooves 9. The two rotating shafts 10 are connected by a belt 11. The transmission path length of the belt 11 is the same as the transmission path length of the conveyor belt 4. A second motor 12 is fixedly installed on the top of the conveying frame 1. The second motor 12 is used to drive the rotation of the rotating shaft 10. When the outer shell is directly stuck in the interior of the conveying frame 1, the end of the collecting shell may be worn due to friction. At this time, when the collecting shell is against the surface of the belt 11, it can move with the outer shell to reduce the loss caused by friction.

[0028] A support rod 13 is fixedly installed inside the transverse groove 9, and the two sides of the support rod 13 are against the two sides inside the belt 11. The support rod 13 ensures that the belt 11 has a certain extrusion force on the outer shell to prevent the collection shell from moving into the transverse groove 9 and avoid deviation caused by punching.

[0029] The support rod 13 includes two straight rods 14 and a concave rod 15. The two straight rods 14 are fixed at both ends of the concave rod 15. The concave rod 15 on one side of the conveying frame 1 is completely located inside the transverse groove 9, and the concave rod 15 on the other side of the conveying frame 1 protrudes from the inside of the transverse groove 9. The punching process is completed in the concave rod 15 section, and the two support rods 13 are in a parallel state.

[0030] Due to the limiting effect of the limiting plate 5, the outer shell needs to be placed from top to bottom. At this time, it is placed at the position of the straight rod 14. When the outer shell moves to the position of the concave rod 15, a part of the collection shell is located inside the transverse groove 9, and the other part is completely located outside the transverse groove 9. At this time, stamping can prevent the punch 7 from lifting the collection shell when it is disengaged. When the punching is completed, the outer shell moves to the position of another straight rod 14, and the outer shell can be easily taken away, or it can move to the terminal with the conveyor belt 4 and fall automatically for easy collection.

[0031] The straight rod 14 and the concave rod 15 are an integrally formed structure to ensure integrity and stability.

[0032] It should be noted that the utility model is a punching device of a hand-plate model. When in use, the outer shell is placed from top to bottom between the two limit plates 5, and the top and bottom of the outer shell are against the surface of the belt 11. At this time, it is placed in the position of the straight rod 14. When the outer shell moves to the position of the inner concave rod 15, a part of the collection shell is located inside the transverse groove 9, and the other part is completely located outside the transverse groove 9. When the conveyor belt 4 drives the outer shell to move to the position of the concave die 6, the punch 7 moves downward to punch. When the punching is completed, the outer shell moves to the position of another straight rod 14, and the outer shell can be easily taken away, or it can fall automatically as the conveyor belt 4 moves to the terminal for easy collection.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
