Detailed Description
See fig. 1. The bracelet ornament structure is a closed ring formed by bracelet materials, wherein the cross section profile of the bracelet materials along the axis direction of the bracelet is formed by two sections of smooth and excessive arcs, and the radius R1 of the outer arc is smaller than the radius R2 of the inner arc contacted with a human body. The contact area between the inner arc radius R2 and the arm of a wearer is large, the contact with the human body is more in accordance with human engineering, the wearing is comfortable, the atmosphere is more obvious with the same weight, and the exposed area is large.
See fig. 2-7. The processing method of the bracelet ornament comprises the following steps:
step one, processing and forming a bracelet material strip.
The processing and shaping bracelet material strip can be formed by one-step stretching on a broaching machine by adopting a stretching die.
And secondly, stamping characters or figures on the contact surface of the bracelet material strip and the human body according to the uniformly distributed distance by using a stamping die.
According to the diameter of the bracelet ornament, the stamping die stamps characters or figures on the contact surface of the bracelet material strip and the human body according to the uniformly distributed distance.
And thirdly, winding the hand ring material with the stamped characters or figures on the optical axis with the spiral strip with the same diameter.
After the characters or the figures are stamped, the diameter of the optical axis is determined according to the diameter of the bracelet ornament, and the bracelet material on the spiral strip winding optical axis is ensured to be cut, separated and welded to be the same as the diameter of the bracelet ornament.
And fourthly, cutting off the bracelet material wound on the optical axis by the diameter spiral strip along the axis of the optical axis to form the open bracelet ornament.
And fifthly, welding the open bracelet ornament into a closed ring shape.
And step six, using a pair roller with grooves corresponding to the shapes of the bracelet material strips to implement rolling shaping treatment on the closed annular bracelet ornament caused by deformation of the punched characters or figures and the welding of the bracelet ornament.
In the embodiment of the processing method of the invention, the stamping die used in the second step comprises the following steps: the hand ring material guiding die comprises a die seat 1, a hand ring material carcass 2, a hand ring material guiding die 3, a guiding die support 4, a stamping head 5 and a stamping head support 6.
The bracelet material tire body 2 is provided with a bracelet material limit groove 2-1 corresponding to the outline shape of the bracelet material, and the bracelet material tire body 2 is arranged in the tire body installation groove 1-1 of the mold seat 1;
the guide die 3 is provided with a bracelet material guide hole 3-1 corresponding to the end face of the bracelet material, the bracelet material guide die 3 is arranged in a mounting hole on the guide die support 4, and the guide die support 4 is fixed on the die seat 1;
one end of the stamping head 5 is provided with a male die 5-1 corresponding to stamping characters or figures, the stamping head 5 is fixedly arranged in a mounting hole of a stamping head support 6 through a fixing bolt 7, the stamping head support 6 is slidably guided and arranged in a mounting groove of the die seat 1, and a stamping head support reset spring 8 is arranged between the bottom of the stamping head support 6 and the die seat 1.
When the stamping die is used, the bracelet material 11 is fed by the stepping feeding mechanism 10, the bracelet material 11 is guided to enter the bracelet material limiting groove 2-1 on the bracelet material carcass 2 through the bracelet material guiding hole 3-1 on the guiding die 3, and the stamping head 5 falls along with the guiding stamping head support 6 under the action of external force (such as the stamping die is arranged on a workbench of a stamping machine), so that characters or figures are stamped on the bracelet material 11 by the male die 5-1. When the external force disappears, the punch head support 6 is reset under the action of the punch head support reset spring 8.
In the embodiment of the processing method of the invention, when the character or pattern punched by the bracelet material 11 is an arc surface, in order to prevent the character or pattern punched by the male die 5-1 from being clearer and prevent the bracelet material from being deformed outwards to generate burrs, the punching end surface of the male die 5-1 on the punching head 5 is an arc corresponding to the punching surface of the bracelet material, and the arc radius of the punching arc end surface of the male die 5-1 is smaller than the arc radius of the punching surface of the bracelet material. The stamping arc end face of the male die 5-1 extrudes and deforms the bracelet material 11 towards the center of the stamping arc end face of the male die 5-1, so that characters or figures are clearer, burrs are not generated at the edge of the bracelet material 11, and a deburring process is saved.
In the embodiment of the processing method, grooves in the pair of rollers used in the step six seal and wrap the bracelet material. Ensure the deformation and shaping of the bracelet material along the length direction.
According to the invention, the hand ring stamping characters or figures with different sizes can be processed by replacing the hand ring material matrix 2, the guide die 3 and the stamping head 5. Realizing the universalization of the stamping die. Greatly reduces the cost of the die.
