Description

Screw squeegee set

The present invention relates to a dentition plate, and more particularly to a set of screw dies.

The screw squeegee set is mainly installed on a boring machine, and at least two correspondingly disposed squeegees are arranged on the boring machine, and a plurality of thread grooves are arranged on the squeegee to A workpiece is interposed between the two dental plates, and the second dental plate is moved in parallel in the opposite direction, so that the workpiece is pressed by the two dental plates, and a thread is formed on the surface of the workpiece, thereby completing the manufacture of a screw. .

Although the dies can easily form a thread on the workpiece, for the tail portion of the screw, limited to the design factor of the slab, usually only a conical shape can be formed, and if other shapes are formed, The shape must generally be divided into at least two stages of manufacturing, that is, the workpiece must be threaded through the jaws and then transferred to another molding machine or cutting machine to suppress the tail of the workpiece or Cutting out the required shape, so that a further process is required, in addition to lowering the production efficiency and increasing the cost; further, since the thread is formed before the tail body is formed, that is, when the tail is formed with the characteristics of the cutting edge If the cutting edge is to be screwed with the thread, since the cutting edge and the thread are formed in sections, it is very difficult to control the guiding edge and the thread phase when the guiding blade is formed. Connect The manufacturing efficiency of such screws is low, and the production yield is difficult to control.

Therefore, the object of the present invention is to provide a screw squeegee set which can quickly form a screw having two guiding edges and a connecting thread under the effect of ensuring the production quality and the production yield.

Therefore, the screw squeegee set of the present invention comprises two corresponding dentition plates, and each of the gingival plates has a dent surface, and a tail forming portion and a shaft body disposed on the dent surface a molding portion and a chip removing portion; wherein the shaft forming portion has a plurality of equally spaced and slanted thread grooves, and the tail forming portion has a plurality of equally spaced slots, and is respectively disposed in the two slots a buffering groove, wherein one end of the slit is in communication with the thread groove; therefore, the design can be such that two sides of the tail of the screw after the tooth decay are formed with two guiding edges, and one end of the guiding blade is connected to the thread, The quick and one-time dental caries can be formed with two guiding edges on both sides of the tail of the screw, and one end of the guiding blade is connected with the screw formed by the thread groove to effectively control the production quality and the yield.

Figure 3 is a perspective view of a screw made in accordance with a preferred embodiment of the present invention.

The foregoing and other technical content, features and effects of the present invention, The detailed description of the preferred embodiments with reference to the drawings will be clearly understood.

Referring to FIG. 1 and FIG. 2, a screw jaw group 3 of the present invention includes two corresponding jaw plates 31, and each of the jaw plates 31 has a tooth surface 311, and one of the jaws 311 is disposed on the 搓a tail forming portion 312, a shaft forming portion 313 and a chip discharging portion 314 on the tooth surface 311; wherein the shaft forming portion 313 has a plurality of equally spaced and inclined thread grooves 3131; and the tail forming portion 312 is provided Between the shaft forming portion 313 and the chip removing portion 314, the tail forming portion 312 has a plurality of slits 3121 disposed at equal intervals, and buffer grooves 3122 respectively disposed between the two slits 3121. One end of the slot 3121 is in communication with the thread slot 3131. In the embodiment, the buffer slot 3122 has a front section 3123 disposed adjacent to the shaft forming portion 313, and a tail end connecting the front section 3123. The segment area 3124, and the groove width 3123D of the front section area 3123 is larger than the groove width 3124D of the tail section area 3124, and the like.

Referring to FIG. 2 and FIG. 3, in the embodiment, when the screw set 3 is used, the mold board 31 is mainly mounted on a boring machine (not shown), and the dent is provided. The flank 311 of the plate 31 is correspondingly disposed, and the dies 31 are mainly used for mounting on a boring machine (not shown); therefore, when the dies 31 are intended to perform a workpiece 4 When the tooth is formed, the workpiece 4 can be input between the two jaw plates 31 such that both sides of the workpiece 4 are respectively held by the tooth surface 31, and when the two jaw plates 31 move in the reverse direction. , the workpiece 4 is rotated under the clamping of the tooth surface 311, and is designed through the thread groove 3131 during the rotation, and gradually A thread 42 is extruded from the shaft 41 of the member 4.

Continuing the foregoing, while the tail forming portion 312 is to clamp the end of the workpiece 4 to form a tail portion 43, by the design of the slit 3121 and the buffer groove 3122, the end of the shaft 41 can be formed during the molding process. The tail portion 43 can be formed with two guiding edges 431 on the cutting groove 3121, and the buffering groove 3122 will help the workpiece 4 to be subjected to the tooth decay process of the tooth plate 31. The guiding blade 431 has a rotation. The gap is effective to prevent the guiding blade 431 from being damaged during the movement of the clamping plate 31, so that the guiding blade 431 can be smoothly formed. Of course, the buffer groove 3122 is designed to have the guiding edge. When the 431 has a space for buffering rotation and the design of the front portion 3123 and the tail portion 3124 is increased, the tail portion 43 can be formed with two different diameter designs.

Finally, the slot 3121 is connected to the thread groove 3131. Therefore, during the forming process of the guiding blade 431, the guiding edge 431 and the end of the thread 42 will naturally be joined together, thereby rapidly forming. A screw having a guiding edge 431 and the guiding edge 431 is connected to the thread 42 is formed. Therefore, compared with the conventional two-stage manufacturing method, the present invention passes through the screw set 3 The design will not only increase the production efficiency, but also determine the screw formed by each of the cavities of the screw set 3, and the guiding edge 431 and the thread 42 will be connected to each other, thereby effectively improving the production quality. With production yield.

In the foregoing, the screw squeegee set of the present invention has a plurality of equally spaced slots formed by the tail body forming portion of the squeegee, and a buffer slot disposed in the two slots, wherein the slot The shaft forming portion is vertically disposed, and And one end of the slot is connected with the thread groove; so that, by the design, a two-lead edge can be formed on both sides of the tail portion quickly and disposablely, and one end of the guide blade is connected to the thread groove The threaded screws ensure the quality of production and increase production yield.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and the simple equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the invention are generally modified. All should remain within the scope of the invention patent.
