Abstract

The invention discloses the processing method of milling tooth groove in key, its manufacturing procedure includes opening key billet, processes tooth groove, it is characterized in that：Tooth groove uses punch process, it is special tartar mould using indispensable process equipment, after stamping out tooth groove on key plug using tartar mould, again the protrusion material on the key plug back side is removed with milling tool, tartar mould includes punch-pin and cavity plate, punch-pin and tooth groove on the key match, die hole is provided with cavity plate, die hole and punch-pin are engaged, because processing method of the invention can use A3 iron plates, the relatively inexpensive material such as stainless steel plate processes key, so being greatly lowered using the cost of the interior milling clavis spoon of hinge lock that the method for the present invention is processed.

Description

The processing method of milling tooth groove in key

Technical field

The present invention relates to one kind lock, in particular, it is related to the interior milling tooth groove of key in blade lock Processing method.

Background technology

At present, the hinge lock of interior milling clavis spoon, with the theftproof performance elegant in appearance and good of its key Increasingly liked by people, the interior milling clavis spoon is the processing method using carving milling in spoon base On spoon body centre, the half of about spoon body thickness carves out tooth groove, and the tooth groove for carving out is in ripple Shape wave, it is very good-looking, but this processing method have the shortcomings that it is very big：Carve the process tool one of milling As using alloy material make straight shank end mill, cutter is expensive and is not durable very much, and process equipment is adopted It is also expensive with engraving machine or numerical control milling-tapping machine and it is necessary to using the material of more crisp easy carving milling, Generally make spoon base material using 59 copper coins, 59 copper coin prices are somewhat expensive, although have extraordinary cutter And process equipment, but its processing efficiency is still very low, therefore production cost is very high；And for price phase To cheap, and the material with toughness, such as A3 iron plates, the material such as stainless steel plate uses carving milling Processing method is difficult processing, so the interior milling clavis spoon cost produced with carving milling method at present Compare high.

The content of the invention

In order to overcome the shortcoming of prior art, A3 iron plates, stainless iron can be used the invention provides one kind The relatively inexpensive material such as plate, stainless steel plate processes the processing of the interior milling tooth groove of key in blade lock Method.

The present invention adopts the following technical scheme that to realize：

The processing method of milling tooth groove in key, its manufacturing procedure includes opening key billet, processes tooth groove,

Tooth groove uses punch process, is special tartar mould using indispensable process equipment, uses After tartar mould stamps out tooth groove on key plug, then removed on the key plug back side with milling tool Protrusion material.

After protrusion material on the removal key plug back side, then punching press removes widening for the upper and lower both sides of key plug Material.

Tartar mould includes punch-pin and cavity plate, and punch-pin and tooth groove on the key match, set on cavity plate Die hole is equipped with, die hole and punch-pin are engaged.

Description of reference numerals：1st, key billet 2, key plug 3, tooth groove 4, the back side 5, Protrusion material 6, punch-pin 7, cavity plate 8, die hole 9, widen material

Specific embodiment

1st, cogging, first outputs key billet with forcing press or other machineries by A3 iron plates or stainless steel plate, As shown in Figure 1；

2nd, punching press tooth groove, the key of forcing press or other machineries in key billet is passed through with tartar mould Required tooth groove is stamped out with it, and principle is, using the method for punching plates, whole tooth groove to be worked as Into the hole not punched through, the punch-pin of tartar mould and tooth groove on the key fit like a glove, cavity plate then with it is convex Mould is engaged, during punching press, in the die hole that the material on key plug gets into cavity plate under the pressure of punch-pin Face, at this moment must control the depth of punch-pin active force, it is ensured that will not punch through, such as Fig. 2, Fig. 3, figure Shown in 4 and Fig. 5；

3rd, the protrusion material on the removal key plug back side, after stamping out tartar, the back side of key plug then can There is material down to protrude, as its shape is with the shape of tooth groove, protrude the height of material also and The depth of tooth groove is about the same, and the material for protruding need to be processed with Tool in Milling such as metal saws and gone Remove.

The present invention in punching press tooth groove, or occur tooth groove scrap (bridge) apart from H it is too small when (such as Fig. 2 It is shown), or cause key plug to deform, the scheme of solution is, in cogging, need to widen key plug Width D (as shown in figure 13), to widen scrap (bridge) apart from H, make not become during punching press tooth groove After shape, so the protrusion material on the key billet removal key plug back side, it is necessary to again plus an operation, key The necessary punching press removal of material is widened in lower both sides with spoon, the width D of key plug is met wanting for design drawing Ask.

At present, milling tooth groove is very popular in key, such as Chinese patent：2012205271241； 2014204610844；2013205020411；2013100406580；It is also a lot, so this hair Bright purposes is very wide.
