Description

Technical Field

[0001] The utility model relates to the technical field of brake drum production, in particular to a punching device used for the production of bimetallic brake drums. Background Art

[0002] A bimetallic brake drum drilling device is a type of equipment designed specifically for bimetallic materials. Its primary function is to precisely drill holes in brake drums. The device typically includes a stable base to support and secure the brake drum, ensuring stability and accuracy during the drilling process.

[0003] For example, the bimetallic brake drum punching device with publication number CN220838043U specifically discloses a base and end plates A and B arranged on both sides of the top of the base, a fixed plate is provided on the lower inner side of the end plate A, a servo motor is installed at the bottom of the fixed plate, the output shaft of the servo motor is connected to a screw rod, a screw block is sleeved on the screw rod, and one side of the screw block is connected to a horizontal support plate; a driving motor is installed at one end of the top of the horizontal support plate, and the output shaft sleeve of the driving motor is provided with a vertical bevel gear, and the other end of the horizontal support plate is provided with a rotating shaft through a bearing sleeve, and the top end of the rotating shaft is sleeved with a horizontal bevel gear, and the bottom end of the rotating shaft is connected to a sliding groove through a connecting sleeve, and the sliding groove is arranged horizontally; a sliding block is slidably connected in the sliding groove, and the bottom end of the sliding block is fixed to the punching motor through a fixed seat.

[0004] The drilling process for bimetallic brake drums requires drilling holes at various locations on the drum. However, existing drilling devices for bimetallic brake drums cannot adjust the drill bit position according to the drilling requirements. This makes it impossible to drill holes at various locations on the drum. Furthermore, the inability to precisely adjust the drill bit position can cause the holes to deviate from the preset point, reducing the drum's machining accuracy. This reduced accuracy can lead to problems during subsequent assembly or use of the drum. Therefore, we propose a drilling device for bimetallic brake drum production. Utility Model Content

[0021] A punching device for the production of bimetallic brake drums includes a base 1, a support 2 is provided at the upper end of the base 1, the support 2 is annular, and the cross-section of the support 2 is L-shaped. A plurality of columns 3 are fixedly installed at the bottom of the support 2, and a disc 4 is fixedly installed at the lower end of the column 3. The disc 4 is connected to the base 1 by screws. A top seat 5 is provided at the upper end of the support 2, and two electric telescopic rods 6 arranged at intervals are fixedly installed on the top seat 5, and the output ends of the electric telescopic rods 6 are fixedly connected to the top seat 5; an inner plate 7 is rotatably installed in the top seat 5, and a plurality of outer shafts 8 distributed in a circular array are rotatably installed at the bottom of the inner plate 7, and external gears 9 are fixedly installed on the outer shafts 8, and a drill bit 10 is fixedly installed at the lower end of the outer shaft 8, a central shaft 11 is rotatably installed on the inner plate 7, and a central wheel 12 is fixedly installed on the central shaft 11, and the central wheel 12 is in a meshing state with the plurality of external gears 9, and a motor 13 is fixedly installed on the inner plate 7, and the output shaft of the motor 13 is fixedly connected to the central shaft 11. The workpiece is placed in the support 2, and the air in the conducting tube 19 is sucked by the negative pressure pump 18, so that negative pressure is generated at the negative pressure hole 17, thereby generating attraction to the workpiece and fixing the workpiece in the support 2. The central shaft 11 is driven to rotate by the motor 13, and the central wheel 12 rotates and drives multiple external gears 9 to rotate, so that the outer shaft 8 and the drill bit 10 can rotate and drill holes. At the same time, the electric telescopic rod 6 drives the top seat 5 to move downward, which can provide drilling force for the drill bit 10.

[0022] The motor 13 is equipped with a protective cover, and the surface of the drill bit 10 is spray-coated with a rust-resistant coating. Multiple brackets 14 are fixedly mounted on the top base 5, each of which is penetrated by a limit rod 15. The top of the inner plate 7 is provided with multiple limit holes 16, into which the lower ends of the limit rods 15 can be inserted.

[0023] Among them, such as Figure 3 and Figure 4 As shown, the support 2 is provided with a plurality of negative pressure holes 17 distributed in a circumferential array, a negative pressure pump 18 is fixedly mounted on the support 2, and a conducting pipe 19 is fixedly mounted on the support 2.

[0024] The working principle of this utility model is as follows: a workpiece is placed within the support 2. A negative pressure pump 18 draws air from the conduit 19, creating negative pressure at the negative pressure hole 17, thereby attracting the workpiece and securing it within the support 2. A motor 13 drives the central shaft 11 to rotate, which in turn drives the central wheel 12 and multiple external gears 9, causing the external shaft 8 and drill bit 10 to rotate and drill a hole. Simultaneously, an electric telescopic rod 6 moves the top base 5 downward, providing drilling force for the drill bit 10. The positions of the multiple drill bits 10 are adjusted by rotating the inner plate 7, and the position of the drill bits 10 is fixed by inserting the limit rod 15 into the limit hole 16. By adjusting the position of the drill bits 10, holes can be drilled at different locations on the brake drum. Precisely adjusting the drill bit position ensures that holes of the correct size and position are drilled on the bimetallic brake drum, thereby improving brake drum manufacturing accuracy. The resulting debris is then diverted through the diversion groove 20 into the storage tank 21.
