Compared with the prior art, the invention has the advantages of high production efficiency, guaranteed size and quality, greatly reduced probability of inferior products, smooth thread pressing, no depth distinction, and no concave-convex lumps generated by rotation in the original machining process and the like.
Description
Technical field
The present invention relates to auto-parts manufacturing technology field, especially relate to a kind of one-time-shaped mould of screw thread ring.
Background technology
At present, usually adopt the mode of punching press for the processing of screw thread ring, its decompressor generally includes a horizontal drift, and being shaped on bed die that screw thread agrees with mutually on this horizontal drift is thread, and matches with this bed die can once stamp out the mold of part screw thread on pipe.In use, at first, stamp out one section screw thread after how upper and lower mould closes with in the laterally inserted intermediate lateral drift of pipe, every up and down punching press once, pipe along screw thread rotation once, until screw thread is combined with the whole thread that encloses.There is following shortcoming in above-mentioned technology: at first, need the repeatedly punching press can global formation, production efficiency be low; Secondly, unstable product quality must be ensured the quality of products according to operating personnel's operational stability, and product quality is directly related with operating personnel's qualification; The 3rd, the screw thread punching press has to be had shallowly deeply, but also can produce concavo-convex pimple in rotary course, has some setbacks; At last, intensity of workers is big, and repeatedly the potential safety hazard brought of punching press increases.
Summary of the invention
Technical problem to be solved by this invention is the present situation at prior art, provides a kind of simple and reasonable, good product quality, one-tenth to produce efficient height, one-time-shaped mould of screw thread ring that labour intensity is low.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of one-time-shaped mould of screw thread ring, comprise mold and bed die, mold comprises cope match-plate pattern, bed die comprises lower bolster, the upper fixed of lower bolster is provided with the following fixedly trim ring with following hollow cavity, the place, upper edge of hollow cavity sets up the following movable forming slide of at least three rounded distributions, has following gap between the movable forming slide down, all be shaped on projection on the inwall of movable forming slide down, all combination of protrusions are the helical form press strips suitable with screw thread ring together, all be shaped on down compressive plane on the outer wall of movable forming slide down, compressive plane from top to bottom slopes inwardly gradually, be provided with lower spring between movable forming slide and the lower bolster down, the centre of following movable forming slide also is provided with the slide block fixed leg; The below of cope match-plate pattern is fixedly connected with the fixedly trim ring of going up with last hollow cavity, upward fixedly the bottom of trim ring bends inwards and forms the support portion, hang with the last movable forming slide of at least three rounded distributions on the support portion, go up between the movable forming slide and have last gap, upward all be shaped on groove on the outer wall of movable forming slide, all groove combination are the helical grooves suitable with screw thread ring together, the inwall of going up movable forming slide is combined and is made its inner space up big and down small and be provided with support column in this space, support column is fixedly connected on the cope match-plate pattern, the middle part of going up movable forming slide is shaped on the boss that is used to push down movable forming slide, goes up between movable forming slide and the cope match-plate pattern and is equipped with upper spring.
In order to obtain better technique effect, further technical measures also comprise:
The vertical section of above-mentioned following movable forming slide compressive plane up and down shows as straight line.
The upper edge of above-mentioned following fixedly trim ring is shaped on and the suitable lower support face of following compressive plane.
The inwall of going up movable forming slide on the vertical section of above-mentioned last movable forming slide shows as straight line.
The lower edge of above-mentioned support column is shaped on the upper support face suitable with the inwall of last movable forming slide.
Above-mentioned following movable forming slide is that the shape of movable forming slide is identical down for eight and each; Go up movable forming slide and be eight and on each the shape of movable forming slide identical.
Compared with prior art, mould of the present invention has the following advantages:
When 1, the mould upper and lower mould was synthetic, the following movable forming slide of rounded distribution pushed to the center, and it is one time punching molded that pipe is inserted the back, the production efficiency height;
2, the depth of thread can be regulated according to last downforce size, and size quality is guaranteed;
3, artificially rely on for a short time, need not in the punching course to adjust, its product quality depends on stabilization of equipment performance, and therefore, the probability that substandard products occur reduces greatly;
4, the screw thread of punching press is along sliding, and no depth difference does not have the concavo-convex pimple that produces because of rotation in the former process.
