Description

A relay moving reed assembly device

technical field

The utility model relates to a riveting device, in particular to an assembling device for a moving reed of a relay.

Background technique

The relay is an electrical control device, which has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). Usually used in automatic control circuits, it is actually an "automatic switch" that uses small currents to control large current operations, so it plays the role of automatic adjustment, safety protection, and conversion circuits in the circuit.

At present, in the relay manufacturing industry, there are three main production methods for silver contacts and moving reeds, armature stamping parts and moving reeds:

1. Manual riveting and assembly, the disadvantages of manual riveting and assembly are many people, low work efficiency, many production links and difficult control of product quality;

2. After the armature stamping parts are assembled, they are riveted by special equipment. The disadvantage of this is that the automatic riveting of special equipment cannot be used universally, and can only be used for the production of a single product, and there are many production processes;

3. Automatic riveting of silver contacts with punching machines, automatic riveting of silver contacts with punching machines is used by domestic enterprises for actual production, but the disadvantage is that armatures cannot be assembled at the same time.

The above-mentioned technical problems have been the problems that the industry has been trying to solve, and it is committed to providing a device with high production efficiency, low cost, good product quality and various product types.

A relay movable reed assembly device, comprising: a punch; a set of stamping and layout upper template and a stamping and layout lower template arranged on the punch, and the stamping and layout template is punched under the action of the punch; the assembled materials There are at least two groups of feeders, which are sent to the feeder of the lower template of the stamping and nesting, and the feeders are placed around the punch press.

Further, there are two groups of feeders, and each group of feeders includes: a circular feeder, installed on the workbench; a straight feeder, one end of the straight feeder is connected to the circular feeder, and the straight feeder The other end is provided with a positioning plate, and the positioning plate is aligned with the lower template of the stamping layout template, which facilitates production and improves production efficiency.

Further, the positioning plate is provided with clamping points for accurately fixing the assembly materials on the feeder, so that the materials on the formwork and the assembly materials can be accurately connected together.

Further, the punch is provided with an upper template, a lower template, and a mold guide column cooperating with the upper and lower templates, and a concave template is installed on the lower template.

Further, the lower template for stamping and layout is provided on the concave template.

Further, the assembly materials include silver contacts and armature stamping parts, the silver contacts are located on one set of feeders, and the armature stamping parts are located on another set of feeders.

Further, the stamping layout lower template is provided with an armature pre-riveting station and a contact pre-riveting station that cooperate with the straight feeder, and the 28 stamping processes of the stamping layout upper and lower templates are After the first step, the moving reed of the relay is formed.

Through the above technical scheme, the beneficial effects are: the positioning accuracy and assembly accuracy are within plus or minus 0.025 mm, the high-speed working efficiency is above 120 strokes per minute, all the high-speed stamping equipment and stamping dies used are localized, and the production efficiency is high. low cost. Especially the new technology of this technology is currently in the domestic relay moving reed manufacturing industry, and its application in assembly technology is still the first. The production efficiency has been doubled, which has great economic value.
