Abstract

The utility model relates to a groove rolling characters device for coins or the like, which comprises a first rotary disc, wherein, a coin-dial device prolonging to the fringe is arranged above the first rotary disc, and a arch groove rolling characters mold arranged on the peripheral of the first rotary disc. Additionally, beside the first rotary disc, the utility model also comprises a second rotary disc, which is also arranged with an arch groove rolling characters mold arranged on the peripheral, with same rotary direction with the first rotary disc. A rolling gap is made between the two discs. With the adoption of the utility model, a much deeper groove can be obtained because the slab is acted by forces bilaterally during rolling, with stable quality, insignificant lapping defect between characters. The significant beneficial effects of the utility model are increasing the capability of anti-counterfeiting and beautifying the appearance of coins or the like.

Description

Coin and analog groove rolling characters device thereof

Technical field

The utility model relates to a kind of device that is used at coin and souvenir badge base cake edge roll extrusion groove and character, belongs to coin and souvenir badge manufacturing technology field.

Background technology

In the false proof structure in edge of coin and analog (for example souvenir badge) thereof, it is a newer anti-counterfeiting technology that groove rolls word.Understand according to the applicant, the groove of coin and analog thereof rolls the principle of the fixing arc template of outer arcuate template that word all adopts a rotation and another piece to stranding both at home and abroad at present, and character is only carved therein on the template.During roll extrusion, the base cake of coin and analog thereof is also made satellite motion with the outer arcuate template in rotation.

Adopt this technology to have following shortcoming: 1. monolateral stressed on the base cake diameter during roll extrusion, the more shallow and difficult control of depth of groove; 2. the end to end lapping defect of character is obvious.

The utility model content

The purpose of this utility model is: the shortcoming at above prior art exists, a kind of coin and analog groove rolling characters device thereof that the word degree of depth is convenient to control, help eliminating lapping defect that roll proposed, and roll the word quality thereby improve groove.

In order to reach above purpose, coin of the present utility model and analog groove rolling characters device thereof comprise first rotating disc, group coin device that extends to the edge is equipped with in described first rotating disc top, the groove that the described first rotating disc periphery is fixed with arc rolls character matrix plate, in addition, also comprise second rotating disc that is positioned at first rotating disc, one side, the groove that the described second rotating disc periphery also is fixed with arc rolls character matrix plate, the rotation direction of described second rotating disc is identical with first rotating disc, forms between two dishes and rolls word space.

During work, two adjacent rotating discs rotate in the same way.Under the base cake of coin, souvenir badge and so on is being dialled the effect of cake device, enter between two rotating discs roll word space the time, the grooves on two dishes roll character matrix plate to carry out producing groove and character to rubbing roll extrusion with the hands to the edge of base cake simultaneously.The base cake from turning around, can be finished the roll extrusion process in the operating position of rolling word space, forms satisfactory groove and character.After adopting the utility model and since during roll extrusion on the base cake diameter both sides stressed, therefore can obtain darker groove, and steady quality, the end to end lapping defect of character is not obvious.Its significant beneficial effect is the anti-counterfeiting performance and the aesthetic property that can improve coin and analog thereof.

The specific embodiment

Embodiment one

The coin of present embodiment and analog groove rolling characters device thereof comprise that mainly batch (-type) dials cake device 1, rotating

disc

2 and 6, groove and roll

character matrix plate

3 and 5 as depicted in figs. 1 and 2.Batch (-type) is dialled rotating disc 2 tops that cake device 1 is installed in the left side, extends to rotating disc 2 edges, can do intermittently to rotatablely move.Right side rotating disc 6 is adjacent with rotating disc 2, forms between two rotating

discs

2 and 6 and rolls word space.During work, two dishes are done the uniform speed rotation, and direction of rotation is identical.Groove rolls

character matrix plate

3 and 5 and is installed in rotating

disc

2 and 6 peripheries respectively.

Dialling cake device 1 when batch (-type) delivers to the base cake 4 of coin, souvenir badge or its analog when rolling the word station, batch (-type) is dialled cake device 1 and is stopped operating, groove rolls

character matrix plate

3 and 5 to carry out rubbing roll extrusion with the hands base cake 4 simultaneously, and base cake 4 is finished the roll extrusion of groove and character in the process that circles certainly.Then, batch (-type) is dialled cake device 1 and is begun to rotate, and base cake 4 is delivered to the discharging station.

As shown in Figure 3, be equipped with in the middle of first rotating disc 2 of dialling cake device 1 is installed in during actual the manufacturing, both sides are installed the second and the 3rd rotating disc 6,6 ' respectively, form between adjacent two dishes and roll word space.Each rotating disc periphery all is equipped with four uniform grooves and rolls character matrix plate 3 and 5.Middle first rotating disc, 2 tops are equipped with batch (-type) and are dialled the cake device, dial the cake pawls for total uniform eight.When coin, souvenir badge or its analog base cake on left and right both sides are dialled the cake device and are delivered to the roll extrusion station of the first rotating disc both sides respectively by batch (-type), roll extrusion simultaneously, whole process realizes that two station chargings, two stations are waited to roll, two station roll extrusion and two station dischargings, and work efficiency significantly improves.

The concrete structure that rolls character matrix plate with upper groove as shown in Figure 4, mainly form by top board 3-1, lower platen 3-2 and the roll extrusion template 3-3 fixed combination that is clipped in the middle, top board 3-1 and lower platen 3-2 apposition position form trapezoidal notch, middle roll extrusion template 3-3 stretches into trapezoidal notch, thereby needs the shape of roll extrusion to match with coin, souvenir badge or its analog base cake edge.The advantage of this structure is to reduce the template difficulty of processing, and it is easy to change impaired roll extrusion template, and depth of groove is easy to adjust.

Consider the both fluted shaping in base cake edge, have character to be shaped again,, groove can not accurately be shaped or the base cake skids if both synchronous processing extruding forces are excessive.Therefore, the roll extrusion template is according to earlier thick roll extrusion groove, and the processing sequence of smart again roll extrusion groove and character designs.The circular arc working face of roll extrusion template 3-3 is divided into three sections, and its effect has nothing in common with each other, and as shown in Figure 5, AB section circular arc is thick roll extrusion groove section, its center of circle O ₁Do not overlap with the rotating disc center, depth of groove is slowly deepened when guaranteeing roll extrusion, and its arc length equals half of institute's roll extrusion groove girth.BC section circular arc is smart roll extrusion groove and character field, and it and AB section circular arc are tangent at the B point, and its center of circle O overlaps with the rotating disc center, and its arc length equals half of groove girth of institute's roll extrusion.CD section circular arc is a unloading part, and this section circular arc and BC section circular arc are tangent at the C point, its center of circle O ₂Do not overlap with the rotating disc center.

In addition to the implementation, the utility model can have other embodiments.The technical scheme that all employings are equal to replacement or equivalent transformation formation all drops on the protection domain that the utility model requires.
