Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 and Figure 2 The illustrated die for punching oil holes in a disc-shaped workpiece includes an upper die base 1, a lower die base 2, and a workpiece base 3. The workpiece base 3 includes a connecting module 31 and a workpiece mounting module 32. The workpiece base 3 is fixedly mounted on the top of the lower die base 2 via the connecting module 31. A disc-shaped workpiece 6 is inserted into the workpiece mounting module 32. The disc-shaped workpiece 6 is inserted laterally, so that the opening on its outer wall is exposed and facing upwards. An auxiliary fixing mechanism 4 is installed on the side of the lower die base 2. The auxiliary fixing mechanism 4 can provide a lateral fixing effect for the inserted disc-shaped workpiece 6, so that the disc-shaped workpiece 6 can be stably mounted on the workpiece mounting module 32 to prevent workpiece displacement during punching. The upper die base 1 can move vertically up and down. The device is driven by a lifting power device, which is a common stamping power device and will not be described in detail here. A punching cutter 11 is installed on the bottom surface of the upper die base 1. Since the installation position of the disc-shaped workpiece 6 is fixed, the punching cutter 11 can form a punching effect on the outer wall of the disc-shaped workpiece 6 during the descent of the upper die base 1. Oil holes 61 can be punched on the outer wall of the disc-shaped workpiece 6. Each time the upper die base 1 descends, a set of oil holes 61 can be punched. After a set of oil holes 61 is punched, the worker adjusts the workpiece placement angle and continues to punch until all the oil holes 61 on the outer wall of the disc-shaped workpiece 6 are punched. This utility model has a simple structure and is easy to operate, and can well solve the production needs of punching oil holes 61 on the outer wall of the disc-shaped workpiece 6.

[0019] like Figure 2 As shown, the connecting module 31 has several bolt holes 312. The connecting module 31 is fixedly connected to the top of the lower mold base 2 by bolts. Under this design, the workpiece base 3 is detachably connected and installed. The workpiece base 3 can be replaced according to the shape characteristics of the disc-shaped workpiece 6.

[0020] like Figure 2 As shown, the connection module 31 has a calibration hole 311, such as Figure 1 As shown, a calibration shaft 12 is vertically connected to the bottom surface of the upper mold base 1. The calibration shaft 12 is sized to match the alignment hole 311. The cooperation between the two plays a guiding role in mold closing. During the descent of the upper mold base 1, the calibration shaft 12 can be inserted into the alignment hole 311 to ensure the accuracy of the punching position.

[0021] like Figure 2 As shown, the upper surface of the workpiece mounting module 32 is arc-shaped, and three evenly distributed positioning protrusions 321 are provided on the upper surface of the workpiece mounting module 32. The outer dimensions and spacing of the positioning protrusions 321 match the inner wall of the disc-shaped workpiece 6, so that the disc-shaped workpiece 6 can be positioned during insertion, and the disc-shaped workpiece 6 will not be able to rotate after installation. Figure 3As shown, the characteristic of this type of disc-shaped workpiece 6 is that the oil holes 61 are evenly distributed on the outer wall of the disc-shaped workpiece 6 in pairs. Therefore, this utility model has two cutting grooves 322 on the positioning protrusion 321 located in the center, and two punching cutters 11 are installed on the bottom surface of the upper die base 1. The two cutting grooves 322 are respectively set on the downward movement trajectory line of the two punching cutters 11. The cutting grooves 322 are to match the insertion of the punching cutter 11 so that the punching cutter 11 can punch out through holes. Each descent of the upper die base 1 can punch out two oil holes 61 on the outer wall of the disc-shaped workpiece 6.

[0022] like Figure 1 As shown, the auxiliary fixing mechanism 4 includes a bracket 41 and a push cylinder 42. The bracket 41 is fixedly connected to the lower mold base 2, and the push cylinder 42 is horizontally installed on the top of the bracket 41. The piston rod end of the push cylinder 42 is connected to a pressure plate 43. When the piston rod of the push cylinder 42 extends outward, it can drive the pressure plate 43 to move towards the workpiece mounting module 32. The pressure plate 43 presses against the disc-shaped workpiece 6 laterally, so that the disc-shaped workpiece 6 is fixed and cannot move or fall off on the workpiece mounting module 32. When adjusting the angle of the disc-shaped workpiece 6, the piston rod of the push cylinder 42 needs to be retracted first to release the pressing state.

[0023] After the punching operation is completed, waste material residue will adhere to the punching tool 11, which will affect the next punching operation. Therefore, if Figure 1 As shown, a blower assembly 5 is installed on the upper mold base 1. The blower assembly 5 includes an air inlet pipe 51, which is installed on the side wall of the upper mold base 1. A ventilation duct 52 is provided inside the upper mold base 1. The air inlet pipe 51 is connected to the ventilation duct 52 and provides airflow to the ventilation duct 52. The ventilation duct 52 is provided with two air outlets 53, which are respectively set to correspond to two punching knives 11. Air is blown out from the two air outlets 53 to form an airflow that blows onto the two punching knives 11. This can completely remove the waste residue on the punching knives 11 and keep the punching knives 11 clean.
