Description

Die for producing low-torque cutting self-tapping screw thread plate

Technical Field

The utility model relates to a screw processing production field, in particular to production low moment of torsion cutting self tapping screw dental lamina mould.

Background

The dental lamina mould, divide into two, a length is short, it has the thread to go up, a mould for to screw blank extrusion for finished product screw thread, the dental lamina mould is the most commonly used screw thread instrument when standard fastener trade processing screw and bolt, the dental lamina mould commonly used only has a thread, cause the phenomenon that the screw blank skidded in the course of working easily, make the off-the-shelf rejection rate of screw increase, machine-formed screw is too dull, the usage is also limited, can't change over into when meetting some harder materials, and also extracted very easily.

There is therefore a need for a die for producing a low torque cutting self-tapping screw die to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a production low moment of torsion cutting self tapping screw dental lamina mould for add man-hour screw blank and not skid, the finished product screw has the cutting function.

The technical proposal adopted by the utility model to solve the technical problem is that,

the utility model provides a production low moment of torsion cutting self tapping screw dental lamina mould, includes quiet dental lamina and moves the dental lamina, it can remove in quiet dental lamina top to move the dental lamina, quiet dental lamina all is equipped with lines of tooth, anti-skidding line and turns round the muscle line with moving the dental lamina upper surface, the groove that constitutes lines of tooth, anti-skidding line and turn round the muscle line is parallel to each other, anti-skidding line is connected with turning round the muscle line, still set up the cutting lines of tooth on the quiet dental lamina, the cutting lines of tooth are located the lines of tooth tail end.

Furthermore, the tooth lines, the anti-slip lines, the twisted rib lines and the cutting tooth lines form an included angle smaller than 10 degrees with the long edges of the static tooth plate and the movable tooth plate.

Furthermore, the long side of the movable tooth plate is larger than the long side of the static tooth plate, and the length of the short side of the movable tooth plate is consistent with that of the short side of the static tooth plate.

Further, dental lamina mould exit is equipped with the finished product screw, the finished product screw includes bottom, tooth and turns round the muscle, the tooth has the cutting tooth on, turn round the muscle and turn round the muscle line through the dental lamina mould and form, tooth passes through the tooth line and forms, the cutting tooth forms through cutting tooth line.

The utility model has the advantages that,

(1) the anti-slip lines are arranged on the static tooth plate and the movable tooth plate, so that the situation that unprocessed screws cannot be processed normally in the processing process can be prevented, and the rejection rate is reduced.

(2) The cutting lines are arranged at the tail ends of the tooth lines on the static tooth plate, cutting teeth can be formed on teeth of finished bolts, friction force of finished screws is increased in actual use, the finished screws can penetrate through special materials, the screws have cutting capacity, and practicability is greatly improved.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the drawings and the specific embodiments.

As shown in figure 1, the utility model provides a production low moment of torsion cutting self tapping screw dental lamina mould, include quiet dental lamina (1) and move dental lamina (2), it can remove in quiet dental lamina (1) top to move dental lamina (2), quiet dental lamina (1) all is equipped with lines (5), anti-skidding line (3) and turns round muscle line (4) with moving dental lamina (2) upper surface, the groove that constitutes lines (5), anti-skidding line (3) and turn round muscle line (4) is parallel to each other, anti-skidding line (3) are connected with turning round muscle line (4), still set up cutting lines (6) on quiet dental lamina (1), cutting lines (6) are located lines (5) tail end. The tooth lines (5), the anti-slip lines (3), the twisted rib lines (4) and the cutting tooth lines (6) form an included angle smaller than 10 degrees with the long edges of the static tooth plate (1) and the movable tooth plate (2). The long edge of the movable tooth plate (2) is larger than the long edge of the static tooth plate (1), and the length of the short edge of the movable tooth plate (2) is consistent with that of the short edge of the static tooth plate (1). Dental lamina mould exit is equipped with finished product screw (7), finished product screw (7) include bottom (71), tooth (73) and twist muscle (72), cutting tooth (74) have on tooth (73), twist muscle (72) and turn round muscle line (4) through the dental lamina mould and form, tooth (73) form through tooth line (5), cutting tooth (74) form through cutting tooth line (6).
