Description

Technical Field

[0001] The utility model relates to the technical field of bending of relay contact pieces, and particularly relates to a hook device for relay contact pieces. Background Art

[0002] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirement, it is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit. It has an interactive relationship between a control system (also called an input circuit) and a controlled system (also called an output circuit). It is usually applied to an automatic control circuit. In fact, it is an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] At present, a traditional relay is composed of an electromagnet, a contact group, a housing and other components. Among them, the electromagnet is composed of an iron core, a coil, an armature and a contact piece. Since, as shown on the left side of the traditional contact piece, Figure 8 bending lug protrusions are fixedly connected to both sides thereof, and the bending lug protrusions are perpendicular to the contact piece. One end of the bending lug protrusion is closer to the coil. When the bending lug protrusion is at a low voltage in the later stage, it can be used for discharging. However, as the voltage in the coil is too high, at this time, the voltage in the coil easily flows into the contact piece through the bending lug protrusion, thereby forming a short circuit and causing the contact piece to be punctured.

When the material taking platform 310 moves to the parking platform 32, at this time, the relay to be bent is conveyed to the material taking platform 310 through the first conveyor belt 2. At this time, the material taking platform 310 moves to the auxiliary platform 33 under the action of the forward movement pneumatic rod 37. At this time, wait for the reciprocating feeding assembly 5 to convey the relay to be bent into the bending assembly 4.

[0038] Embodiment 3

[0039] As Figures 1 - 8 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0040] The reciprocating feeding assembly 5 includes a bent column 51. The bent column 51 is fixedly connected to the top surface of the bending table 41. A lifting pneumatic rod 52 is fixedly connected to the bottom surface of the bent column 51. The output end of the lifting pneumatic rod 52 is fixedly connected with a transverse track 53.

[0042] Working principle and usage process of the utility model:

[0043] In the working state:

[0044] During operation, first, start the forward moving pneumatic rod 37. As the forward moving pneumatic rod 37 works, it will drive the side plate 38, the extension plate 39, and the material taking table 39 to move forward. When the material taking table 39 moves to the parking table 32, at this time, the forward moving pneumatic rod 37 stops working. Then, the first conveyor belt 2 starts to work. When the first conveyor belt 2 works, it moves the unbent relay forward, thus transporting the relay to be processed onto the material taking table 310. When the relay to be processed is located on the material taking table 310, the forward moving pneumatic rod 37 will drive the unprocessed relay and the material taking table 310 to move to one side of the auxiliary table 33 and stop the work of the forward moving pneumatic rod 37. At this time, start the horizontal pneumatic rod 55 in the reciprocating feeding assembly 5. As the horizontal pneumatic rod 55 moves, it will drive the sliding frame 56 to move forward. When the sliding frame 56 moves above the relay to be processed, start the lifting pneumatic rod 52. As the lifting pneumatic rod 52 works, it will drive the sliding frame 56 to move downward, so that the unbent relay is located within the clamping opening 57. At this time, start the horizontal pneumatic rod 55 again. When the horizontal pneumatic rod 55 works, it can move the unbent relay from the material taking table 310 to the auxiliary slider 42, and the bent relay on the auxiliary slider 42 will be moved onto the second conveyor belt 6, which is convenient for transportation to the next process for processing;

[0045] When the unbent relay is located on one side of the first U-shaped positioning block 45, start the clamping pneumatic rod 462 at this time. As the clamping pneumatic rod 462 works, it will drive the clamping plate 463 and the second U-shaped positioning block 464 to move towards the relay. At this time, with the cooperation of the second U-shaped positioning block 464 and the first U-shaped positioning block 45, the unbent relay can be clamped;

[0046] When the second U-shaped positioning block 464 moves, it will drive the bending plate 465 to move. When the unbent relay is clamped, the L-shaped inclined blocks 468 will be located on both sides of the relay to be processed. At this time, start the bending pneumatic rod 466. As the bending pneumatic rod 466 moves, it will drive the bending rod 467 to move. As the bending rod 467 moves, it will drive the L-shaped inclined blocks 468 to move, thus starting to bend the contact piece through the L-shaped inclined blocks 468.
