Problems solved by technology

Therefore, the deburring process needs to be processed in two strokes. Generally, the inner 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 with figure 2 , an inner flanging punch described in a preferred embodiment of the present invention includes a deburring core 10 and an inner flanging jacket 20 detachably connected to the deburring core 10 . One end of the deburring mold core 10 is a deburring end 11, and the other end is a connecting end 12. The deburring end 11 is tapered in diameter gradually narrowing toward the connecting end 12. The deburring mold core 10 is installed in the inner hole 21 of the inner flanging overcoat 20, one end of the inner flanging overcoat 20 is the inner flanging end 22, the other end is the mounting end 25, and the outer diameter of the mounting end 25...

Abstract

The invention relates to an inward flanging punch, comprising a deburring mold core, one end of which is a deburring end, and the other end is a connecting end, the deburring end is in the shape of a cone whose diameter gradually narrows toward the connecting end, so The outer wall of the connecting end is close to the deburring end and the outer wall of the deburring end is provided with a collecting tank with a semicircular cross-section; The deburring mold core is installed in the inner hole of the inner flanging jacket, one end of the inner flanging jacket is an inner flanging end, and there is a gap between the inner flanging end and the deburring end; wherein, the The inner hole is a stepped hole with a first hole section and a second hole section, the second hole section is tapered in diameter gradually narrowing toward the first hole section, and the inner diameter of the first hole section is smaller than the first hole section. The minimum inner diameter of the second hole section, the connecting end of the deburring core is installed in the first hole section through fasteners.

Description

technical field [0001] The invention relates to the field of pipe end forming molds, in particular to an inward 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 inner 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 carried out first, and then the deburring operation is performed. Because the...
