Description

[Technical field]

[0001] The utility model relates to the technical field of precious metal jewelry processing, in particular to a method for manufacturing threads by processing pure gold wire and the technical field of manufacturing jigs. [Background technology]

[0002] Precious metals are used as metals for jewelry. Casting or surface finishing are common processing methods in the jewelry industry. With the advancement of processing technology, there are many ways to process the surface, and multiple processes are superimposed on each other until a jewelry piece with exquisite decorative effects is obtained.

[0003] The most critical quality parameter of the pure gold products we buy daily and the pure gold jewelry we wear is the purity of gold. The higher the purity, the more valuable it is. Only when various products are processed based on pure gold can they be valuable and gain market recognition. However, due to the density of the material itself, pure gold has high purity but a soft texture, that is, the hardness of pure gold with high purity is not enough. Generally, common specifications and thicknesses can be deformed by human hands. Moreover, if machine processing is required, it is easy to cause process damage such as clamping deformation, compression and bending. Therefore, the most critical thing in the processing of pure gold is to consider the hardness of pure gold.

[0004] The existing industry needs to process spiral thread patterns on pure gold wires. Compared with other processed products, the demand for such processing is not particularly large, so gold wires / gold wires with a diameter of about 3 to 5 mm are processed manually, and then the spiral patterns are manually carved. The entire processing process: first, the gold wire is clamped at both ends with a clamping device with elastic clamping pads, and then the thread patterns are manually carved with a thread engraving knife. The efficiency is low, the scrap rate is high, and the consistency of the processed products is poor.

[0005] With the strong demand for processing, such production capacity and effect cannot meet the requirements of processing companies. It is necessary to design thread processing fixtures and processing methods that can automatically process and improve processing efficiency. [Summary of the invention]

[0006] The utility model relates to a method for processing and manufacturing pure gold wire threads, wherein a thread processing jig is proposed. The pure gold wire thread processing jig is equipped with a servo drive motor, which clamps the gold wire through a chuck and drives the gold wire to be screwed in / out in a processing cutter to process a thread pattern, thereby improving work efficiency, reducing scrap rate, and greatly improving the consistency of finished product processing products.

[0007] The pure gold wire thread processing jig is characterized in that the processing jig includes a servo motor, a clamping head, a slide rail, a sliding seat and a thread processing tool. The driving shaft of the servo motor is inserted into the clamping head to drive the clamping part of the clamping head to rotate. A slide rail and a sliding seat clamped on the slide rail are provided under the clamping head. A thread processing tool is provided on the sliding seat. The supporting center point of the thread processing tool is maintained on the same horizontal line as the clamping position of the clamping head.

[0008] A base plate is provided below the slide rail, a motor fixing seat is provided at one end of the base plate, and the servo motor is installed at the end of the base plate through the motor fixing seat.

[0009] The clamping head has a clamping hole groove, in which a clamping part for clamping the pure gold wire is arranged. The clamping part includes clamping claws evenly distributed around the circumference and a flexible clamping pad arranged on the inner wall of the clamping claw. The clamping claw contacts and clamps the pure gold wire with its flexible clamping pad.

[0010] The sliding seat is sleeved on the sliding rail, and a limiting member is provided at one end of the sliding rail away from the motor fixing seat, and the limiting member limits the farthest displacement of the sliding seat.

[0011] The limiting member is a limiting convex column.

[0012] The thread machining tool comprises a tool seat body and a rotary thread cutter head arranged in the tool seat body.

[0013] The tool seat body includes an integrally formed fixing portion and a locking portion. The fixing portion is fixed on the sliding seat by screws, and the locking portion is a tool head adjustable fixing structure. The aperture size of the locking portion is adjusted to adapt to different types of threaded tool heads.

[0014] The locking portion is in an incomplete circular ring shape and has a missing opening. Screws and screw fastening structures are provided on both sides of the missing opening. The internal aperture size of the locking portion is adjusted by screwing the screws in / out.

[0015] The rotary thread cutter head comprises a circular cutter body and three cutting edges arranged on the inner wall of the circular cutter body. The three cutting edges are evenly distributed around the circumference, and a chip removal hole is provided between two adjacent cutting edges.

[0016] A method for manufacturing the thread machining jig using the thread machining jig, characterized in that it comprises the following steps:

[0017] Step 1: insert one end of the pure gold wire into the clamping head, clamp the gold wire through the clamping part, and release the wire appropriately;

[0018] Step 2: Select the corresponding spiral thread cutter head according to the thickness of the gold wire;

[0019] Step 3: Insert the other end of the pure gold wire into the rotating thread cutter head of the thread processing tool;

[0020] Step 3: Turn on the servo motor to drive the wire to rotate. When the wire rotates forward, the rotary thread cutter head on the wire rotates in the direction of the servo motor through the sliding seat, and rotates out away from the servo motor when the wire rotates reversely.

[0021] Step 4: After the sliding seat drives the thread machining tool to process once, it will reverse / forward repeatedly two or three times to cut the thread and clean the thread groove debris to ensure that the machined surface is smooth and free of fine adhesion.

[0022] The pure gold wire thread processing involved in the utility model is equipped with a servo drive motor, and a chuck clamps the gold wire to drive the gold wire to rotate forward / reverse to process a thread pattern. In view of the characteristics of pure gold, which has a relatively soft texture, a flexible clamping pad is used to process it at a low speed to cope with the insufficient situation, thereby improving efficiency and strictly controlling the consistency of the product to obtain a better processing effect.

[0034] The clamping head 20 has a clamping hole 21, in which a clamping part 22 for clamping the pure gold wire is provided. The clamping part 22 includes clamping claws 221 evenly distributed around the circumference and a flexible clamping pad 222 provided on the inner wall of the clamping claw 221. The clamping claw 221 contacts and clamps the pure gold wire with its flexible clamping pad 222.

[0035] The sliding seat 40 is sleeved on the sliding rail 30 , and a stopper 41 is provided at one end of the sliding rail 30 away from the motor fixing seat 12 , and the stopper 41 limits the maximum displacement of the sliding seat 40 to prevent the sliding seat from slipping out.

[0036] The position-limiting member 41 is a position-limiting convex column. The convex column protruding from the position-limiting member is arranged on the upper surface of the slide rail 30, which supports the sliding seat 40 and limits the maximum distance that the sliding seat can move.
