Description

How to process the lead angle for the installation position of the water control valve on the faucet body

The present invention relates to a processing method of a faucet body, in particular to a method of processing a leading angle for the installation position of a water control valve. The technology of the present invention can prevent the water control valve from being scratched by burrs or sharp angles.

As shown in Figure 1, the faucet body is usually set up like a T-shaped pipe structure; the first end A provides the water inlet pipe (end) connection, the second end B provides the water outlet pipe (end) connection, and the third end C Then the water control valve D assembly is provided, and by controlling the water control valve D, the tap water flows from the water inlet pipe to the outlet pipe side. As shown in Figure 2, the water control valve D is used to close or open the first end A through a water-stop rubber E, thereby introducing tap water or stopping water.

As shown in Figure 3, since the faucet body is mostly made from casting or forging molds, the straight holes at the first end A and the second end B are mostly processed by machine tools, and the holes left after processing are If there are burrs F or sharp corners, you need to deburr or remove the sharp corners to prevent the burrs F or sharp corners from scratching the water-stop rubber E.

As shown in Figure 4 and Figure 5, the faucet body currently removes the third The burrs F or sharp corners of the straight holes at one end A and the second end B are removed (or trimmed) by using the CNC machine tool with the boring tool G (Figure 4) or the forming tool H cutting method (Figure 5). chamfering, rounding); however, the disadvantages of the above technology are:

1. As shown in Figure 4, there is an eccentricity problem when machining the faucet through CNC tool machining because the faucet body is made of blank material. It is easy to have incomplete removal of burrs or sharp corners on one side, which in turn causes the water-stop rubber E to be scratched by the burrs F.

2. If the technology in Figure 5 is used, special forming tools need to be customized, which increases the cost of the industry, and CNC tool machining costs are high. In addition, machining with CNC tools requires a long processing time, which virtually increases the industry’s costs. Manufacturing costs.

How to solve the inconvenience caused by conventional processing methods is an issue that relevant industry players are actively solving.

The main purpose of the present invention is to provide a method for processing the lead angle of the installation position of the water control valve of the faucet body. It mainly uses a punch to drive a processing punch to stamp the first end or the second end. The processing punch is provided with an opposite end. The rounded corners of the first or second end holes should be squeezed by the punching machine to smooth the surface of the water control valve installation position, so that the water control valve can rotate smoothly and prevent the water-stop rubber from being scratched by burrs or sharp angles. loss.

For this reason, the present invention is achieved through the following technologies:

Step 1: Place the blank of a faucet body in a fixture. The faucet body is a T-shaped tube, which includes a first end and a second end. The first end and the second end include each other. holes on the same axis, and the faucet body also has a third end arranged between the first end and the second end, and the third end is provided with a water control valve;

Step 2: A stamping machine is provided with a processing punch. The processing punch includes a connecting end and at least one forming end. The connecting end is connected to the punching machine. The forming end is arranged at the bottom of the connecting end and is connected to the connecting end. An annular shaped portion is provided at the connection, and the aforementioned shaped end can penetrate into the hole of the first end or the second end;

Step 3: The aforementioned punching machine drives the processing punch to advance toward the first end or the second end, and the forming part of the forming end is pressed against the periphery of the hole at the first end or the second end to remove the burrs on the hole. Squeeze to remove.

In an embodiment of the present invention, the shaped portion is a rounded corner.

In an embodiment of the present invention, the shaped portion is a leading angle.

In an embodiment of the present invention, the shaped end includes a first processing portion corresponding to the first end and a second end corresponding to The second processing part is provided with a first forming part at the connection between the first processing part and the connecting end, and a second forming part is provided at the connection between the second processing part and the connecting end. The punching machine drives the processing punch to face the The first end and the second end are advanced to remove the burrs of the holes at the first end and the second end.

Through the above description, the advantages of the processing method of the present invention are as follows:

1. The present invention improves the processing method of burrs or sharp angles of the holes at the first and second ends of the conventional faucet body, which not only speeds up the processing but also reduces costs.

2. The method of removing burrs in the present invention is through extrusion processing through the forming part of the forming end. Therefore, as long as the processing position of the processing punch is correct, the burrs or sharp angles on the holes can be removed and the holes on both sides can maintain consistent smoothness. The water-stop rubber on the water control valve is smooth to use and will not be scratched by burrs or sharp angles.
