[0032] Embodiment

[0033] As Figure 1-7 shown, this embodiment provides a punching and bossing die for a clutch coil housing, including: an upper die 1 and a lower die 2. The upper die 1 includes: an upper die base 11 and a punch 12 provided at the bottom end of the upper die base 11; the lower die 2 includes: a lower die base 21 and a die cavity 22 provided above the lower die base 21. A clutch coil housing 3 is adaptively installed between the punch 12 and the die cavity 22. The punch 12 is provided with a bossing member 121 and a punching member 122. The bossing member 121 and the punching member 122 are used to perform bossing 33 and punching through-hole 32 operations on the clutch coil housing 3.

[0034] Among them, the clutch coil housing 3 is the workpiece to be processed, which is specifically annular with a hollow middle. The clutch coil housing 3 is provided with an inner groove 31 for installing a coil, and two through-holes 32 are provided in the inner groove 31. A boss 33 is provided adjacent to the through-hole 32, and the boss 33 is provided on the outer side surface of the clutch coil housing 3, that is, on the surface opposite to the inner groove 31. The bossing member 121 is used to punch the boss 33, and the punching member 122 is used to punch the through-hole 32. The through-hole 32 is used to install a crystal chip so that the clutch coil housing 3 can be connected to a power source. This die can perform bossing 33 and punching through-hole 32 operations simultaneously, that is, the boss 33 and the through-hole 32 are formed together without the need for step-by-step processing, which is convenient to use and has high working efficiency.

[0035] Meanwhile, the convex platform member 121 includes a height adjustment mechanism 1211 disposed within the punch 12 and a convex platform module 1212 disposed on the height adjustment mechanism 1211. The protruding height of the convex platform module 1212 is controlled by the height adjustment mechanism 1211, so that the convex platform module 1212 can punch convex platforms 33 with different heights to adapt to clutch coil housings 3 with different requirements, and the applicable range is wide.

[0036] In this embodiment, both the convex platform member 121 and the punching member 122 are preferably punch pin structures, because punch pins can achieve reliable connection at a relatively high frequency and speed, and the durability and stability of punch pins are relatively high, and they can withstand more insertion and extraction times and mechanical stresses. Moreover, the punch pin structure is easier to clean and maintain because there is no curved shape and space to accommodate impurities.

[0037] In this embodiment, the height adjustment mechanism 1211 includes an electric push rod 12111 disposed within the mounting hole 123 of the punch 12 and a connection block 12112 disposed between the electric push rod 12111 and the convex platform module 1212. The connection block 12112 can prevent the convex platform module 1212 from directly contacting the electric push rod 12111, which can reduce the wear of the electric push rod 12111 and thus extend the service life of the electric push rod 12111. The electric push rod 12111 drives the connection block 12112 to move reciprocally, so that there are multiple options for the height of the convex platform module 1212. Moreover, the electric push rod 12111 is convenient to control, can quickly move to the designated position, has a low use cost, and the height adjustment mechanism 1211 has a simple structure and is convenient for disassembly and assembly.

[0038] In this embodiment, a protruding portion 124 is formed at the bottom end of the punch 12. The protruding portion 124 is adapted to the inner groove 31, specifically, the protruding portion 124 is inserted into the inner groove 31 for positioning, to prevent the clutch coil housing 3 from being not installed in place and resulting in unprocessability. A plurality of limiting members 125 are uniformly distributed at the bottom end of the protruding portion 124. The limiting members 125 are used to position and limit the clutch coil housing 3 to prevent it from disengaging from the punch 12 or shifting during processing, ensuring the stability of the clutch coil housing 3 during processing.

[0039] In this embodiment, the punching member 122 and the convex platform punching member 121 are sequentially distributed circumferentially along the bottom surface of the protruding portion 124, and the specific numbers of the punching member 122 and the convex platform punching member 121 can be determined according to the numbers of the convex platforms 33 and through holes 32 required on the clutch coil housing 3. Preferably, two through holes 32 and one convex platform 33 are provided on the clutch coil housing 3. Correspondingly, preferably two punching members 122 and one convex platform punching member 121 are provided. The positions of the punching member 122 and the convex platform member on the punch 12 correspond to the positions of the convex platform 33 and the through hole 32 on the clutch coil housing 3, so that the convex platform 33 and the through hole 32 can be processed and formed at one time, with simple operation and convenient use.

[0040] In this embodiment, the protruding portion 124 is adaptively installed in the installation groove 222 at the bottom end of the female die 22, and the outer diameter of the protruding portion 124 should be smaller than the outer diameter of the installation groove 222, with a certain distance left between the two. This distance is used to install and accommodate the clutch coil housing 3 to be processed. That is, the thickness of the protruding portion 124 is the width of the inner groove 31, and the height of the protruding portion 124 is the depth of the inner groove 31.

[0041] In this embodiment, a frustum 221 is formed in the middle of the female die 22. The clutch coil housing 3 is inserted onto the frustum 221. The installation groove 222 is arranged on the outer circumference of the frustum 221. The outer diameter of the frustum 221 is smaller than the inner diameter of the protruding portion 124, and the outer diameter of the frustum 221 is equal to the inner diameter of the clutch coil housing 3. The installation groove 222 is used to install the clutch coil housing 3. When installed, the opening of the inner groove 31 faces upward. At this time, the inner and outer diameters of the installation groove 222 are the inner and outer diameters of the clutch coil housing 3.

[0042] In this embodiment, the frustum 221 is arranged opposite to the accommodation groove 126 in the protruding portion 124 to avoid dislocation, which may cause the situation that the clutch coil housing 3 is not installed in place, and further cause the problem of inability to process.

[0043] In this embodiment, a first groove 223 and a second groove 224 adapted to the punching member 122 and the convex platform punching member 121 are respectively arranged in the installation groove 222. The size of the first groove 223 is larger than the size of the through hole 32, so that the punching member 122 can completely punch and form the through hole 32. The size of the second groove 224 should be equal to the size of the convex platform 33 to ensure that the convex platform punching member 121 can punch and form the convex platform 33 and avoid incorrect processing.

[0044] Of course, a chip discharging groove 225 is provided on one side of the female die 22, and the chip discharging groove 225 is communicated with the installation groove 222. The chip discharging groove 225 is used to discharge the residual chips in the first groove 223 to ensure the cleanliness of the female die 22 and prevent it from affecting the next processing.

[0045] In addition, a plurality of ejector pins 226 are arranged in the installation groove 222. The ejector pins 226 are used to eject the processed clutch coil housing 3, which is convenient to take. The operation is simple and convenient, and there is no need to spend a lot of effort to take out the clutch coil housing 3.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
