Description

Regular polygon blank cake edge knurling device
Technical field
The present invention relates generally to a kind of device that the base cake edge of coin and analog thereof is carried out rolling, especially a kind ofly the regular polygon blank cake edge is carried out roll extrusion make its device that forms a circle protuberance, the invention still further relates to the manufacture method of special-purpose template in this device simultaneously.Belong to coin and analog manufacturing technology field thereof.Regular polygon among the present invention is made broad understanding, comprises regular geometries such as quincunx.
Background technology
At present, circular coin and analog thereof (for example souvenir badge) form evenly full protuberance periphery for after final figure line impression processing, need carry out rolling processing before impression earlier.Make base cake periphery projection slightly.Like this, when final mold pressing, can form evenly full protuberance periphery smoothly.
Yet, for the polygon coin, also do not have to carry out the relevant device of rolling processing at present, and be difficult to form evenly full protuberance periphery without the direct impression of rolling processing, can't satisfy the product quality requirement.
Summary of the invention
The objective of the invention is to: propose a kind of regular polygon blank cake edge knurling device that can finish the processing of polygon blank cake edge knurling, have the technology difficult problem of grand limit structure coin and analog thereof thereby solve to make.
In order to reach above purpose, regular polygon blank cake edge knurling device of the present invention comprises rolling dish, the outer arcuate template that is fixed on rolling dish periphery, the arc template that is fixed on rolling dish one side and outer arcuate template formation raceway that can rotate around its center, the feed mechanism that is positioned at arc template feed end, its innovation part is, a described outer arcuate template side relative with the arc template be shaped on respectively with rolling after the curve that matches of regular polygon blank cake gabarit.
More than the curve of inside and outside arc formwork can obtain by analytical Calculation, also can obtain by generating motion.Rolling adds man-hour, and the rolling dish of this device rotates under motor-driven, drives the rotation of outer arcuate template, jointly the regular polygon blank cake that feed mechanism is sent into raceway is carried out rubbing roll extrusion with the hands with fixed arc template, makes base cake periphery projection slightly.In this process, regular polygon blank cake is when making revolution motion, also make spinning motion, owing to be shaped on the curve that matches with polygon coin gabarit on the inside and outside arc formwork, therefore regular polygon blank cake is as pure rolling, and not only by smooth, and peripheral each point is stressed evenly, can roll out satisfactory dimpling periphery, thereby have laid a good foundation for finally impressing.

The specific embodiment
Embodiment one
The regular polygon blank cake edge knurling device of present embodiment as shown in Figure 1, mainly by the rolling dish 1 that can rotate, fixed interval around its center in the outer arcuate template 2 of rolling dish 1 periphery, be fixed on that rolling dish 1 one sides and outer arcuate template 2 form the arc template 5 of raceway, the feed mechanism that is positioned at arc template 5 feed ends is formed.
Wherein outer arcuate template 2 and arc template 5 relative sides are shaped on vee-cut (referring to Fig. 3 A, 3B), the profile of vee-cut bottom for rolling after the curve (referring to Fig. 4 A, 4B) that matches of regular polygon blank cake gabarit, have a breach (referring to Fig. 5) at arc template 5 one ends.1), make the gabarit shape moulding rolling consistent with regular polygon blank cake and advise (referring to Fig. 6 A, B) this curve gains enlightenment from the principle of the extruding that is shaped, and manufacturing process is:; 2), utilize the moulding rolling rule inside and outside arc formwork vee-cut to annealed condition on rolling device harden to carry out roll extrusion, make the vee-cut bottom form corresponding contour curve; 3), quenching makes inside and outside arc formwork reach required hardness.
The feed mechanism of present embodiment (referring to Fig. 2) is by the locating piece 4 that is fixed on arc template 5 feed ends (locating piece 4 one ends with arc template 5 one the end breach is equal be connected), and the feeding push pedal 8 that elasticity presses tongue 6, be installed in the electromagnetic viscosimeter funnel 7 of top, the arc template 5 feed ends outside, be installed under the electromagnetic viscosimeter funnel 7 constitutes.Because the radius difference of regular polygon blank cake edge each point, in the time of in entering edge knurling mould, the base cake must have phase place accurately, accurately locatees at rolling starting point place in order to guarantee the base cake, and the interior hole shape and the regular polygon blank cake of electromagnetic viscosimeter funnel 7 match.
During the positive hendecagon base of roll extrusion cake (other base cake can be analogized), after base cake (3) enters electromagnetic viscosimeter funnel (7), adjusted phase place by the endoporus of electromagnetic viscosimeter funnel (7), base cake behind the location is advanced by the feeding push pedal (8) that level moves back and forth, the base cake is by arc template (5) one end breach, send into base cake locating piece (4) top, bossing by locating piece (4) top carries out pre-determined bit to base cake (3), simultaneously elasticity presses tongue (6) that base cake (3) is pressed into locating piece (4) bottom, can guarantee that the base cake accurately sent into the raceway original position.
As seen from Figure 1, positive hendecagon base cake (3) is tangent with fixing arc template (5) starting point N in original position.When outer arcuate template (2) is rotated with rolling dish (1), when arriving another point of contact M of base cake (3), base cake (3) rolls with simultaneously tangent beginning of two templates.In this process, when base cake (3) revolves round the sun along with rolling dish (1), also around its geometric center rotation.Base cake (3) is when rolling moves, and the track of each point motion is rerun a movie on the outer arcuate template (2) of rotation and fixing arc template (5), illustrates M when base cake (3) arrives 1O 1N 1During the discharging position, just finished whole rolling process.
Facts have proved, after adopting the device of present embodiment, can thoroughly solve a technology difficult problem of making regular polygon coin and analog thereof with grand limit structure, guarantee both quality and quantity to realize the rolling processing to the regular polygon blank cake edge, the protuberance periphery of guaranteeing to impress the back regular polygon is even, full, attractive in appearance.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
