Abstract
The utility model discloses a combined double-alloy dental plate used for the processing of threads of tapping screws, comprising a group of dental plate dies. The right sides of the dental plate dies are provided with tapping screw forming threads; the front upper ends of the tapping screw forming threads on the right sides of the dental plate dies are provided with fixed slots; the fixed slots are internally provided with dental plate heads made of high-speed steel; the dental plate heads are rectangular in shapes and provided with fixed screw holes on the right sides; the tapping screws penetrate through the fixed slots of the dental plate dies to be directly screwed in the fixed screw holes; and the threads of dental plate heads are successively and correspondingly connected with the tapping screw forming threads. The utility model adopts antiwear high-speed steel and antiwear titanizing technology to manufacture the dental plate heads, and the dental plate heads can be replaced so that the dental plate dies can be reused to greatly reduce waste.
Description
Technical field:
The utility model relates to-kind of metal processing dental lamina; Relate in particular to a kind of processing dental lamina of self tapping tooth screw.
Background technology:
The existing dental lamina mould that is used to make processing self tapping tooth screw, the tooth line by dental lamina mould front end comes work earlier, and the damage great majority of tooth line all are the front ends at the dental lamina mould.When the tooth line of dental lamina mould front end has surpassed the tooth line after service life, front end tooth line damages, and other position of dental lamina mould is not but damaged.Because the tooth line of dental lamina mould front end damages monoblock dental lamina mould and just can not use, caused the waste of processing dental lamina, product amortization cost is many.
The utility model content:
For damaging, the front end tooth line that overcomes existing dental lamina mould makes the bad technical deficiency of monoblock dental lamina wear soon; The purpose of this utility model just provides a kind of high-speed steel titanizing dental lamina head combined type self tapping tooth screw pairing golden tooth plate that is provided with changeable type at tooth template front end tooth line, improve tooth silk service life, after the dental lamina head damaged, changing the dental lamina head just can be without monoblock dental lamina mould.
For realizing that the technical scheme that the utility model purpose is taked is:
The processing of a kind of screw thread of self tapping tooth screw comprises one group of dental lamina mould with combined type pairing golden tooth plate, and screw moulding tooth line is established in the front of dental lamina mould, it is characterized in that: the processing front end at the screw moulding tooth line in dental lamina mould front is provided with a holddown groove; Be fixed with a dental lamina head in holddown groove, the front of dental lamina head is provided with dental lamina head tooth line; Dental lamina head tooth line is identical with the structure and specification of the screw moulding tooth line of dental lamina mould, and the tooth line of both each bar correspondences connects continuously.
Described two dental lamina moulds to pressure are equipped with a dental lamina head at correspondence position.
Described dental lamina head is the square type, is located at the preceding upper corners position of processing of dental lamina mould, i.e. the preceding upper end of processing of screw moulding tooth line.
The dental lamina mould front end at described holddown groove rear portion is provided with dental lamina mould fixing hole, and the dental lamina head back side is provided with the fixed screw holes of dental lamina head, and dental lamina head and dental lamina mould are fixed through screw.
The dental lamina head tooth line of described dental lamina head and screw moulding tooth line are on a line on same plane.
The tooth line of self tapping tooth screw is tilting, and the utility model also is applicable to the processing of other screws.
The beneficial effects of the utility model are: the utility model adopts the front end of dental lamina mould that the dental lamina head of high-strength alloy is set, replace the tooth line position that dental lamina mould front end damages easily, the tooth card head that the dental lamina front end is provided with is after service failure, can change the dental lamina head, and the dental lamina mould need not be with changing, being connected of dental lamina head and dental lamina mould is to adopt screw directly to link to each other, and reduced the waste of screw processing dental lamina like this, improves the performance of enterprises.

The specific embodiment:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Among the embodiment as Fig. 1～shown in Figure 5, the utility model comprises one group of dental lamina mould 1, and screw moulding tooth line 11 is established in the front of dental lamina mould 1.Upper corners position before the processing in dental lamina mould 1 front, i.e. the preceding upper end of processing of screw moulding tooth line 11 is provided with a holddown groove 13.Establish dental lamina mould fixing hole 12 on the dental lamina mould 1 at holddown groove 13 rear portions.Be provided with the dental lamina head 2 of a high-speed steel material in holddown groove 13, dental lamina head 2 is the small rectangular block type.The front of dental lamina head 2 is provided with dental lamina head tooth line 21, and the rear portion of dental lamina head 2 is provided with dental lamina head fixed screw holes 22, and dental lamina head 2 and dental lamina mould 1 are fixed through screw.Screw passes dental lamina mould fixing hole 12 and is fixed in the fixed screw holes 22.Dental lamina head tooth line 21 is identical with screw moulding tooth line 11 structure and specifications, the in one plane seamless continuous connection of the tooth line 14 of both each bar correspondences.The tooth line 14 of self tapping tooth screw is tilting, and being suitable for processing needs.
As long as dental lamina head 2 damages, changing dental lamina head 2 just can be without monoblock dental lamina mould 1.
Dental lamina head material is the SKH-9 high-speed steel, and dental lamina mould material is SKD-11.Dental lamina head 2 adopts anti abrasive high-speed steel material and wear-resistant technology for plating titanium manufacturing to form.The dental lamina head then adopts the high-strength alloy different with dental lamina mould 1, has improved wearability 30%, uses to improve wearability behind the titanium alloy and can reach 50%.
As Fig. 6, Fig. 7, shown in Figure 8, self tapping tooth screw processing bar material is pushed down the beginning section between the dental lamina mould 1 of pressing at two in process, increases between two dental lamina moulds pressure, and offset in opposite directions, make tooth line 14 rub silking on the surface of self tapping tooth screw processing bar material to pressing.Obviously the beginning section of processing is stressed relatively big, and it is also fast to wear and tear.So dental lamina head 2 is set is proper solution.
The utility model also is applicable to the processing of other screws.
