Abstract
A method for chamfering the installation position of a water control valve of a faucet body, mainly using a punching machine to drive a processing punch to punch a first end or second end, where the processing punch is provided with a fillet corresponding to the hole of the first end or second end, which squeezes the burrs through the driving of the punching machine, allowing the surface of installation position of the water control valve to be even and smooth, achieving smooth rotation of the water control valve, and preventing the water stop rubber to be scratched by the burrs or sharp corners.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0028] Referring to FIGS. 6 to 8, a method for chamfering the installation position of a water control valve of a faucet body of the present invention mainly includes the following steps: [0029] Step 1: as shown in FIG. 6, the blank of a faucet body 100 being placed in a fixture 200, where the faucet body 100 is a T-typed pipe, including a first end A and second end B including holes A1 and B1 on the same axis as each other, and a third end C between the first end A and second end B is further provided on the faucet body 100, where the third end C provides a water control valve D (as shown in FIGS. 1 and 2), since the water control valve D is not the focus of the improvement in the present invention, the detail thereof is omitted here, where the faucet body 100 is made of copper (brass, bronze, lead-free copper, free-cutting copper) belonging to soft metals in metal property and being easy to be processed; [0030] Step 2: as shown in FIG. 7, a punching machine 300 being provided with a processing punch 301 including a connecting end 302 and forming end 303, the connecting end 302 being connected with the punching machine 300, and the forming end 303 being configured on the bottom of the connecting end 302 and provided with an annular forming portion 304 on the connection of the forming end 303 with the connecting end 302, the forming end 303 can penetrate the hole A1 of the first end A or the hole B1 of the second end B, where the punching machine 300 may be a horizontal punching machine or a toggle-type punching machine, and mainly drives the processing punch 301 toward the first end A or the second end B side in a manner of driving in a plane direction; and [0031] Step 3: as shown in FIGS. 8 and 9, the punching machine 300 driving the processing punch 301 to move toward the first end A or second end B (the figures show a single direction as an illustration), and the forming portion 304 of the forming end 303 being pressed against the hole A1 of the first end A or the hole B1 of the second end B and the forming portion 304 being used to further squeeze and remove the burrs F on the hole A1 or B1 as FIG. 9 shows; since the faucet body 100 is made of soft metal, the burrs F or the sharp corners being capable squeezed and removed without the need for a punching machine 300 with an excessively large tonnage. It is worth to mentioned that the forming portion 304 can use chamfers or fillets to process the holes A1 and B1, so as to make the peripheries of the holes A1 and B1 even and smooth.
[0032] Referring to FIGS. 10 and 11, a processing punch 401 used in another preferred embodiment of the present invention is derived from the one shown in FIGS. 7 and 8, having a T-shaped structure. A forming end 403 includes a first processing portion 404 corresponding to the first end A and a second processing portion 405 corresponding to the second end B; a first forming portion 406 is provided on the connection of the first processing portion 404 with a connecting end 402, and a second forming portion 407 the connection of the second processing portion 405 with the connecting end 402. Whereby, a punching machine 400 drives the processing punch 401 to push against the first end A and the second end B to remove the burrs F on the hole A1 of the first end A and the hole B1 of the second end B, so that the burrs on the first end A and second end B can be processed in one punching operation.
[0033] Through the above description, the present invention has the following advantages compared to the prior arts: [0034] 1. the present invention improves the method for processing the burrs or sharp corners on the hole A1 of the first end A and the hole B1 of the second end B of the faucet body 100, which not only can speed the processing but reduce costs.
according to the present invention, the burrs F or sharp corners are removed by means of the squeeze of the forming portion 304 of the forming end 303, so that the burrs on the holes A1 and B1 can be removed as long as the processing position of the processing punch 301 is correct and the holes A1 and B1 at the two sides are allowed to be kept consistent smoothness, allowing the water stop rubber E on the water control valve to be used smoothly and not to be scratched by the burrs F.
