Description

Technical Field

[0001] The utility model belongs to the technical field of punching processing of plate-shaped parts of wind power generation, and in particular relates to a precision punching die for plate-shaped parts of wind power generation. Background Art

[0002] During the punching operation of plate-like components for wind power generation using a punching die, burrs are easily generated on the edges of the punched holes. The burrs are easily drawn into the gap between the punch and the edge of the hole due to the upward dragging effect during the resetting process of the punch, causing the punch to be pulled on the punch and deformed, thereby reducing the quality and accuracy of the punching process. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a precision punching die for plate-like components of wind power generation. The rotating punch, which can stop and rotate, switches from a stopped state to a rotating state during the resetting process, so that the rotating punch removes burrs on the edge of the hole of the plate-like component, thereby improving the quality and accuracy of the punching process.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a precision punching die for a plate-shaped component of a wind power generation, comprising an upper die structure and a lower die structure, wherein the upper die structure is connected to a punching machine so that the punch of the upper die structure faces the lower die structure;

[0005] The punch is a rotary punch installed on an upper die structure, and the upper die structure also includes a punch rotation driving device and a punch stopping device. The rotary punch can switch between rotation and stopping states through the driving action of the punch rotation driving device and the stopping action of the punch stopping device.

[0006] Furthermore, when the rotary punch follows the upper die structure to move downward for punching, the rotary punch is in a stopped state due to the stopping action of the punch stopping device; when the rotary punch follows the upper die structure to move upward for resetting, the rotary punch is in a rotating state due to the driving action of the punch rotation driving device.

[0007] Furthermore, the rotary punch includes an integrally formed punch portion, a tooth portion and a shaft portion, and the rotary punch is rotatably mounted on the upper mold structure through the shaft portion; the punch rotation drive device includes a motor and a gear set, and the motor drives the rotary punch to rotate through the transmission of the gear set and the tooth portion; the punch stopping device includes a pair of brake shoes symmetrically distributed about the shaft portion, the pair of brake shoes include two states: an embraced state and a separated state, and the pair of brake shoes clamp the shaft portion in the embraced state to stop the rotary punch.

[0008] Furthermore, the brake shoe has a transverse support rod, and the transverse support rod slides through the vertical support plate on the upper mold structure.

[0009] Furthermore, the punch stopping device also includes a stopping cylinder corresponding to the brake shoe one by one, and the piston rod of the stopping cylinder is connected to the lateral support rod of the brake shoe.

[0010] Furthermore, a guide sleeve corresponding to the transverse support rod is embedded on the vertical support plate, and the transverse support rod axially slides through the guide sleeve.

[0011] Beneficial effect: The utility model switches the stoppable and rotatable rotary punch from a stop state to a rotation state during the resetting process, so that the rotary punch removes burrs on the edges of holes of plate-like parts. The removed burrs are not easily carried upward into the gap between the punch and the edge of the hole due to the rotating circumferential driving effect of the rotary punch, thereby avoiding the burrs entering the gap between the punch and the edge of the hole and causing the punch to be pulled and deformed by the resetting of the punch, thereby improving the punching processing quality and accuracy.

[0014] Attached Figure 3 It is a schematic diagram of the structure of a rotary punch and a punch rotation driving device. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] As attached Figure 1 As shown, a precision punching die for a plate-shaped component of a wind power generation system comprises an upper die structure 1 and a lower die structure 2. The upper die structure 1 is connected to a punching machine 3 so that the punch of the upper die structure 1 faces the lower die structure 2. Figure 1 and attached Figure 2As shown, the punch is a rotary punch 4 installed on the upper die structure 1, and the upper die structure 1 also includes a punch rotation driving device 7 and a punch stopping device 6. The rotary punch 4 can switch between the rotation state and the stopping state through the driving action of the punch rotation driving device 7 and the stopping action of the punch stopping device 6. More specifically, when the rotary punch 4 follows the upper die structure 1 to move downward to punch holes, the rotary punch 4 is in the stopping state through the stopping action of the punch stopping device 6; when the rotary punch 4 follows the upper die structure 1 to move upward to reset, the rotary punch 4 is in the rotating state through the driving action of the punch rotation driving device 7. The utility model switches the stopperable and rotatable rotary punch 4 from a stopperable state to a rotating state during the resetting process, so that the rotary punch removes burrs on the edge of the hole of the plate-like component. The removed burrs are not easily brought upward into the gap between the punch and the edge of the hole due to the rotating circumferential driving effect of the rotary punch, thereby avoiding the burrs entering the gap between the punch and the edge of the hole and causing the punch to be pulled and deformed by the resetting of the punch, thereby improving the punching processing quality and accuracy.

[0017] As attached Figure 2 and attached Figure 3 As shown, the rotary punch 4 includes an integrally formed punch head 41, a toothed portion 42 and a shaft body 43, and the rotary punch 4 is rotatably mounted on the upper die structure 1 through the shaft body 43; the punch rotation drive device 7 includes a motor 71 and a gear set 72, and the motor 71 drives the rotary punch 4 to rotate through the gear set 72 and the toothed portion 42; the punch stop device 6 includes a pair of brake shoes 62 symmetrically distributed about the shaft body 43, and the pair of brake shoes 62 includes two states of embracing and separation, and the pair of brake shoes 62 clamp the shaft body 43 in the embracing state to stop the rotary punch 4. In order to improve the stability of clamping the shaft body 43, uniform textures can be provided on the clamping concave surface of the brake shoe 62 to increase friction.

[0018] As attached Figure 2 As shown, the brake shoe 62 has a transverse support rod 64, and the transverse support rod 64 slides through the vertical support plate 63 on the upper mold structure 1. A guide sleeve 65 corresponding to the transverse support rod 64 is embedded on the vertical support plate 63, and the transverse support rod 64 axially slides through the guide sleeve 65. The transverse support rod 64 is responsible for providing support for the brake shoe 62 and also provides guidance for the displacement of the brake shoe 62. The punch stop device 6 also includes a stop cylinder 61 corresponding to the brake shoe 62, and the piston rod of the stop cylinder 61 is connected to the transverse support rod 64 of the brake shoe 62. The stop cylinder 61 is also installed on the upper mold structure 1 in a transverse posture.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
