Description

Bending method for making nails

Technical field

The present invention relates to a kind of manufacture method of nail, the Binding Instrument that particularly a kind of operation is used belongs to technical field of medical instruments with the manufacture method of nail.

Background technology

The Binding Instrument of in the past making the operation use with the method for following closely is: at first select a stainless steel wire consistent with diameter or titanium silk for use, then use nipper plier its bending to be converted into the shape that needs of nail, cut off with scissors then, cut two inclined-planes following closely pin at last with the file file or with scissors.Select for use the system nail process of this method not only time-consuming but also require great effort, and, caused the fraction defective of the used nail of Binding Instrument very high because the size of nail is very little.And two inclined-planes of nail pin are difficult to make and are shaped, and can't satisfy the needs of clinical use.

Summary of the invention

Purpose of the present invention is exactly in order to solve the above-mentioned problems in the prior art, and a kind of bending method for making nails is provided.

Purpose of the present invention is achieved through the following technical solutions: bending method for making nails, to make the nail raw material is arranged on the mould, mould is spaced, form recess, recess and cutting knife cutter head form fit, when cutting knife during towards the mould punching press, the system nail stressed bending of raw material and blocked by cutting knife, the cross section is cut forms nail pin inclined-plane, makes a plurality of Binding Instruments with following closely.

Purpose of the present invention can also come further to realize by the following technical programs:

Above-mentioned bending method for making nails, wherein, described cutting knife is "T"-shaped, and the head of cutting knife is a drift, and the edge of a knife is positioned at the cutting knife end.

Further, above-mentioned bending method for making nails, wherein, the described edge of a knife and drift are one or two parts independently.

Bending method for making nails, wherein, it is wavy that system nail raw material is bent into concavo-convex continuous rectangle, three cutting knifes are " product " font and arrange, constitute the cutting knife group, and the trend of cutting knife group matches with system nail raw material shape, system nail raw material is blocked when forming nail pin inclined-plane also makes a plurality of Binding Instruments with following closely.

Further, above-mentioned bending method for making nails, wherein, wavy height of aforesaid rectangle and spacing evenly distribute.

Further, above-mentioned bending method for making nails, wherein, the trend of cutting knife group is staggered front to back interlock for level.

Again further, above-mentioned bending method for making nails, wherein, the trend of cutting knife group is staggered interlock about level.

The present invention produces Binding Instrument with nail by the method that adopts a kind of bending system nail, makes Binding Instrument realize mass production with nail.Two inclined-planes of nail pin produce in process of production naturally, and two inclined-planes of nail pin are evenly distributed, and the yields height satisfies medical clinical needs.Its manufacture process of production method of comparing is in the past simply talked about, and production cost also decreases, and has expanded the space for the technological progress of this area, and implementation result is good.

The specific embodiment

" embodiment one "

As shown in Figure 1: bending method for making nails, at first will make nail raw material 2 and closely be arranged on the mould 1, system nail raw material 2 normally one with Binding Instrument with following closely consistent stainless steel wire or the titanium silk of diameter.Mould 1 is for being spaced, between formed the recess of evenly arranging, its recess and cutting knife 3 cutter head form fit.By using cutting knife 3 to carry out punching press towards mould 1.

As shown in Figure 2: system nail raw material 2 is stressed to begin to produce deformation, blocks by bending and by cutting knife at last.As shown in Figure 3: because cutting knife 3 integral body are "T"-shaped, the head of cutting knife 3 is a drift, can better must be used to make the bending of nail raw material 2, and the edge of a knife 4 is positioned at the cutting knife end.And the edge of a knife 4 and drift can be one, also can be two parts independently.In the process of bending system nail, the cross section of system nail raw material 2 also forms nail pin inclined-plane 5 naturally when being cut, after whole process finishes, just make a plurality of complete, independently Binding Instrument is with nail 6.

" embodiment two "

As shown in Figure 4: bending method for making nails, at first will making nail raw material 2, to be bent into concavo-convex continuous rectangle wavy, and the wavy height of rectangle and spacing evenly distribute.Then, as shown in Figure 5: in system nail process, the F-SP of system nail raw material 2 can finely must cooperate the trend of cutting knife group and arranging of the edge of a knife.As can be seen from the figure, three cutting knifes are " product " font arranges, and constitutes the cutting knife group, promptly constitutes upper cutter 31a, lower cutter 31b, and their interval matches with the shape of system nail raw material 2, and the trend of cutting knife group is staggered front to back interlock for level.As shown in Figure 6: after system nail raw material 2 was blocked, the concavo-convex end up and down of rectangle wave had all formed complete, two independent parts respectively.And in this process, nail pin inclined-plane 5 forms naturally, has realized producing in batches the purpose of Binding Instrument with nail 6.

" embodiment three "

As shown in Figure 7: bending method for making nails, at first will making nail raw material 2, to be bent into concavo-convex continuous rectangle wavy, and the wavy height of rectangle and spacing evenly distribute.Concavo-convex continuous shape can be produced by coiling machine.Then, as shown in Figure 5: in system nail process, the F-SP of system nail raw material 2 can finely must cooperate the trend of cutting knife group and arranging of the edge of a knife.As can be seen from the figure, the cutting knife group comprises that at least 3 are upper cutter 31a, the lower cutter 31b that " product " font is arranged, and their interval matches with the shape of system nail raw material 2.Be that with the difference of " embodiment two " as shown in Figure 7: the recess at system nail raw material 2 is provided with tray 7, guarantees in upper cutter 31a, lower cutter 31b tangent line process, system nail raw material 2 does not come off easily.And the trend of cutting knife group is staggered interlock about level in the present embodiment.In implementation process, come system nail raw material is carried out tangent line by staggered interlock about the level of cutting knife group.Can be that upper cutter 31a, lower cutter 31b move staggered interlock simultaneously, also can have independent one group to realize motion.Its purpose all is to realize the wavy system nail of concavo-convex continuous rectangle raw material is separated up and down, cuts.Because the shape of cutting knife limits, that the concavo-convex end up and down of rectangle wave has all formed respectively is complete, two independent parts promptly follows closely 6.And in this process, nail pin inclined-plane 5 forms naturally, has realized producing in batches the purpose of Binding Instrument with nail 6.

Claims

1, bending method for making nails, it is characterized in that: will make the nail raw material and be arranged on the mould, mould is spaced, and forms recess, recess and cutting knife cutter head form fit, it is "T"-shaped that cutting knife is, and the head of cutting knife is a drift, and the cutting knife end is provided with the edge of a knife, when cutting knife during towards the mould punching press, system is followed closely the stressed bending of raw material and is blocked by cutting knife, and the cross section is cut forms nail pin inclined-plane, makes a plurality of Binding Instruments nail.
