Problems solved by technology

Therefore, the deburring process needs to be processed in two strokes. Generally, the flanging operation is performed first, and then the deburring operation is performed. Since the two processes cannot be carried out at the same time, and the above method has complicated procedures and low production efficiency

Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] see figure 1 and figure 2 , a flanging punch described in a preferred embodiment of the present invention includes a flanging core 10, and a deburring jacket 20 is detachably connected to the flanging core 10. One end of the flanging mold core 10 is the flanging end 11, and the other end is the connecting end 12, and the flanging edge end 11 is in the shape of a cone whose diameter gradually increases toward the connecting end 12; the flanging mold core 10 is installed on the deburring In the inner hole 21 of the sheath 20 , one end of the deburring sheath 20 is a deburring end 22 , and there is a gap between the deburring end 22 and the burring end 11 . Wherein...

Abstract

The invention relates to an external flanging puncher pin which comprises an external flanging mold core and a deburring outer sleeve. One end of the external flanging mold core is an external flanging end, and the other end of the external flanging mold core is a connecting end. The external flanging end is in the shape of a cone with the diameter gradually increasing towards the connecting end; a holding part sunken inwards is arranged in the middle of the connecting end; and a penetrating hole penetrating through the holding part and used for being connected with a wrench is formed in the holding part. The deburring outer sleeve is in detachable connection with the external flanging mold core and the external flanging mold core is mounted in an inner hole of the deburring outer sleeve; one end of the deburring outer sleeve is a deburring end; and a gap is arranged between the deburring end and the external flanging end. The inner hole is a step hole with a first hole section and a second hole section; the inner diameter of the first hole section is smaller than the inner diameter of the second hole section; the connecting end of the external flanging mold core is mounted in the first hole section through a fastener; the second hole section forms the deburrning end; and a chamfer is formed in the step portion of the second hole section.

Description

technical field [0001] The invention relates to the field of pipe end forming processing dies, in particular to a flanging punch. Background technique [0002] The quality of the copper pipe deburring nozzle has always been a bottleneck in the pipe end forming process. The quality of the processing directly affects the efficiency of the inner pipe and the upper quick connector. Since the current pipe end forming dies only have two types, the common flaring die and the shrinking die, there is no special deburring punch. [0003] In order to ensure the quality requirements of the upper quick connector and the inner piping, it is often necessary to deal with the burrs and the outer flanging problems at the same time to ensure the size requirements of the inner and outer diameters of the copper pipes. Therefore, the deburring process needs to be processed in two strokes. Generally, the flanging operation is performed first, and then the deburring operation is carried out. Becau...
