Definitions

• the present application relates to a punch die device, in particular a CNC punch die upper die device.
• the purpose of the present application is to provide a numerical control punching die upper mold device, and to increase the adjustment state maintaining mechanism while maintaining various adjustment functions of the Chinese patent Z L200520065714. 7, so that the adjustment operation is simple and convenient.
• the upper punching device of the numerical control punching die comprises a guiding sleeve assembly, the guiding sleeve assembly is provided with a locking ring, the locking ring is sleeved on the outer side of the upper part of the guiding sleeve, and the locking ring is provided with two a symmetrical annular groove, wherein two ends of the pin are fixed on the guide sleeve and the other end is inserted into the annular groove of the lock ring; the outer cylindrical surface of the upper part of the guide sleeve is provided with two symmetrical annular grooves in the annular concave
• the groove is provided with a compression spring, and one end of the spring of the two annular grooves which are respectively fixed at one end to the lock ring and the other end of which is inserted into the guide sleeve.
• a pressing locking mechanism is disposed between the guiding sleeve and the locking ring, the mechanism is provided with a hook pin and a spring; the hook pin is provided with a locking hook, and the guiding sleeve is provided with a cylindrical hole, and the hole slides with the hook pin
• the spring is disposed in the cylindrical hole; the lower end surface of the lock ring is provided with a hook for the hook pin to be unable to rotate
• the flat groove, the inner end surface of the flat groove is provided with a groove matching the locking hook on the hook pin.
• the front portion of the hook pin described above may be oblate, wherein the lower portion is provided with a toothed lock hook, and the tail portion is cylindrical.
• the working principle of the application is as follows: When the length of the punch extension needs to be adjusted, the lock ring is rotated clockwise, and the flat groove of the lock ring slides along the hook pin of the flattened head, when the groove of the flat groove end face of the lock ring touches When the upper hook pin of the upper hook pin is hooked, the toothed hook is pushed into the groove by the push of the tail spring, so that the lock ring cannot rotate, and the mechanism is in an adjusted state.
• Figure 1 is a schematic view showing the structure of the present application
• Figure 2 is a cross-sectional view taken along line A-A of Figure 1 (in the working state);
• Figure 3 is a cross-sectional view along A-A in Figure 1 (when adjusting state);
• Figure 4 is a cross-sectional view taken along line B-B of Figure 1 (in the working state);
• Figure 5 is a cross-sectional view taken along line B-B of Figure 1 (when the state is adjusted);
• Figure 6 is a perspective view of the hook pin of the present application.
• Figure 7 is a perspective view of the lock ring (bottom up) of the present application.
• the present application includes a striking head assembly 24 and a guide sleeve assembly. 25.
• the core 11 and the stripper 13 are provided.
• the striking head assembly 24 is formed by the die head 1, the two half piece retaining ring 2, the return spring 4, the die guiding rod 5, the guiding pin 6, and the outer cylindrical surface, and is circumferentially equally divided into 12 closed grooves 23.
• the ring 1, the O-ring 19 mounted on the upper surface of the two half-piece retaining rings 1 in the inner groove of the die 1 and the decorative rubber sleeve 3 are composed.
• the return spring 4 is mounted on the die guide 5 between the inner tapered surface of the lower end of the retaining ring 1 and the two half-piece retaining rings 1.
• the die guide 5 is connected to the stop pin guide pin 6 to guide the die guide 5 to move up and down.
• the guide sleeve assembly 25 is composed of a guide sleeve 9, a dial pin 14, a stop pin 15, a compression spring 16, a lock ring 17, and a small steel ball 18.
• the lock ring 17 is movably fitted over the upper portion of the guide sleeve 9, on which two annular grooves 20 are formed.
• One end of the two stop pins 15 is fixedly mounted on the guide sleeve 9, and the other end is inserted into the annular groove 20 of the lock ring 17, and the lock ring 17 is supported so as not to cause axial sway with the guide sleeve 9, only along The two annular grooves 20 are rotated at a small angle.
• An O-ring seal 8 is mounted between the bottom end of the ring 7 and the inner groove of the upper portion of the guide sleeve 9.
• Two symmetrical annular grooves 21 are formed in the guide sleeve 9 between the lock ring 17 and the guide sleeve 9, and a compression spring 16 is mounted in the annular groove 21.
• Two latches 14 are also mounted on the lock ring 17, one end of which is fixedly mounted on the lock ring 17, and the other end of which is inserted into one end of the compression spring 16 in the annular recess 21 of the guide sleeve 9.
• the lock ring 17 is rotated clockwise, the lock ring 17 is rotated at an angle relative to the guide sleeve 9 within the range defined by the annular groove 21.
• the two compression springs 16 push the two dial pins 14 on the lock ring 17, thereby causing the lock ring 17 to rotate and reset.
• the guide sleeve 9 is machined with four small round holes with tapered holes at the inner end, and four small steel balls 18 are built therein.
• the small steel ball 18 falls into the closing recess 23 of the outer surface of the retaining ring 1 in the striking head assembly 24, and the outer surface of the retaining ring 7 is locked by the locking ring 17, so that the striking head assembly 24 is locked.
• the striker assembly 24 can be rotated or can be withdrawn from the guide sleeve assembly 25.
• a guide pin 10 is machined on the punch 11.
• the internal thread of the upper portion of the punch 11 is connected to the external thread of the lower end of the die guide 5.
