Embodiment 1

[0048] Such as Figure 1-Figure 11 As shown, the present embodiment provides a method for processing a nut casing, including a shape processing step, a cutting step and an inner hole processing step;

[0049] Wherein, in the shape processing step, use a grinder to grind the two end faces of the blank of the nut sleeve mold to the finished size, and grind the circumferential surface of the blank of the nut sleeve mold to a cylindrical surface or a conical surface. The shape of cylindrical and conical surfaces can be as figure 1 with figure 2 It should be noted that the ratio and taper of the dimensions in the figure are only schematic and do not mean that the blank still has the taper as shown in the figure under the corresponding dimensions. By grinding the end face of the blank of the nut sleeve die to the finished product size, and then wire-cutting into multiple sheet dies, the more accurate surface can be used as the positioning reference during the wire-cutting process...

Embodiment 2

[0072] Such as Figure 17As shown, the difference between this embodiment and Embodiment 1 is that Embodiment 1 uses a complete clamp cover and clamp seat to realize the clamping of the semi-finished nut sleeve mold. In fact, it is also possible to directly use the nut sleeve mold processing jig with processing seams to realize clamping nut sleeve mold. The fixture cover 20 has an inner hole, and a first processing slit is also provided on the fixture cover 20 , and the first processing slit extends from the inner surface of the internal control to the side of the fixture cover 20 .

[0073] By setting the first processing seam on the fixture cover 20, the cutting wire can only cut the nut cover mold 40 every time the nut cover mold 40 is processed, and will not cut the fixture cover 20, which reduces the cutting area of ​​wire cutting , thus improving the processing efficiency.

[0074] More specifically, the fixture seat 10 is provided with a second processing slit 21, the...

Embodiment 3

[0077] Such as Figure 10 As shown, a nut sleeve mold is made by the above-mentioned nut sleeve mold processing method, including a mold sleeve and a sheet mold 41, and the multi-sheet sheet molds 41 form a circular ring together, and the multi-sheet sheet molds 41 are embedded in the mold sleeve 50 in.

[0078] The nut sleeve mold processed by the above method has high machining accuracy, not only the dimension tolerance of the polygonal inner hole is low, but also the verticality between the inner hole and the end face of the nut sleeve mold is high, which is beneficial to process better quality nuts .

Abstract

The invention provides a nut combined die machining method and a nut combined die machine tool adopting the nut combined die machining method and relates to the technical field of manufacturing of machining dies of nuts. The nut combined die machining method comprises steps of appearance machining, cutting and inner hole machining. In the cutting step, a semi-finished nut combined die product obtained in the appearance machining step is fixed in a nut combined die machining jig, (N-1) piece dies are cut out in a linear cutting manner, N is the number of piece dies required for forming one nutcombined die, and the direction of cutting wires in linear cutting is parallel with the axis direction of the nut combined die machining jig. The technical problem of side angle errors of machined nutcombined dies in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing a processing mold for a nut, in particular to a method for processing a nut casing mold and a nut casing mold using the nut casing molding processing method. Background technique [0002] At present, in the production of special-shaped nuts in our country, tungsten steel 4-piece combined mold or 6-piece combined mold is basically used to improve the service life of the mold, and the piece mold is basically processed by grinding. Especially for sheet molds with a thickness of 0.5mm or less, the processing is difficult, the precision is low, and the preparation process is long. [0003] Its disadvantages include the following problems: 1. The processing is difficult, because the processing of the side of the sheet mold needs to adjust the angle, and the conditional angle is easy to cause errors and the shape is limited; 2. It takes time to prepare and process; 3. It is easy to grind Generate ...
