Abstract
The utility model discloses a forming die for a spiral tooth-shaped clamp belt. The forming die comprises a lower die (1) and an upper die (2). The lower die (1) and the upper die (2) are provided with die grooves. A lower embedding block (3) is arranged in the die groove of the lower die (1). The upper end surface of the lower embedding block (3) is an arc surface (4). A forming worm is arranged on the arc surface (4). An upper embedding block (6) is arranged in the die groove of the upper die (2). Threaded teeth (7) corresponding to the forming worm (5) are arranged on the upper embedding block (6). The forming die is a dedicated die especially designed to extrude corrugate bow-shaped protruding straight teeth, and has the advantages of being simple in structure, convenient to use, easy to machine, low in production cost and long in service life. Extruded clamp belts are large in clamping force and not prone to releasing.
Description
Technical field
The utility model relates to a kind of mould of screw serrated form shell ring, belongs to pipeline securing member manufacturing technology field.
Background technology
At present screw serrated form clip commonly used mostly is the strip hole of going out on its shell ring, meshes the shell ring diameter that dwindles or enlarge looped-shaped bending by the thread on the worm screw in the case and the strip hole on the shell ring, to reach banding or to loosen the purpose of pipeline.Above-mentioned this screw serrated form clip, tightening force is less, if tightening force is large a little, with regard to being easy to the strip hole on the shell ring is drawn distortion, causes slide fastener, and service life is short.In order to solve the problems of the technologies described above, the applicant has designed a kind of screw serrated form clip, and the profile of tooth on the shell ring of this clip is the arc outstanding straight-tooth of corrugated, and tensile property is good, not yielding and slide fastener, long service life.But existing equipment can't squeeze out the arc outstanding straight-tooth of corrugated.
Summary of the invention
The purpose of this utility model is, a kind of mould of screw serrated form shell ring is provided.The profile of tooth that is specifically designed on the shell ring of extrusion spiral profile of tooth clip is the arc outstanding straight-tooth of corrugated.
The technical solution of the utility model
A kind of mould of screw serrated form shell ring comprises counterdie and patrix, and counterdie and patrix are provided with die cavity, is provided with down in the die cavity of counterdie and inserts, and lower upper surface of inserting is arc surface, and arc surface is provided with the moulding worm screw, is provided with in the die cavity of patrix and inserts; On insert and be provided with the thread corresponding with the moulding worm screw.
In the mould of said spiral profile of tooth shell ring, be provided with backstay in the die cavity of described counterdie, lower insert, on insert and be provided with locating hole.
In the mould of said spiral profile of tooth shell ring, described counterdie is provided with guide post, and patrix is provided with pilot hole.
Compared with prior art, existing mould can not squeeze the arc outstanding straight-tooth of corrugated.The utility model is special particular manufacturing craft for the arc outstanding straight-tooth design of extruding corrugated, has simple in structure, easy to use, handling ease, production cost is low and the characteristics of long service life.The shell ring tightening force that squeezes out is large, is difficult for threading off.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the face upwarding stereogram of Fig. 1.
Be labeled as among the figure: the 1-counterdie, insert under the 2-patrix, 3-, the 4-arc surface, 5-moulding worm screw is inserted on the 6-, 7-thread, 8-backstay, 9-locating hole, 10-guide post, 11-pilot hole.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.
