Description

Technical Field

[0001] The invention relates to the field of socket copper piece processing, in particular to a cutting device for processing copper pieces for switch sockets. Background Art

[0002] Switch and socket copper parts mainly refer to the copper parts used to conduct current inside switches and sockets. The electrical contacts of the sockets are obtained by cutting the copper parts and then bending and forming the cut copper sheets.

[0003] From a functional perspective, in a socket, the copper part is the part that directly contacts the metal pins of the plug. Its function is to establish a safe, stable and efficient electrical connection so that the current can flow smoothly from the socket to the electrical equipment connected to the plug. For example, in common three-hole and five-hole sockets, the internal copper parts can fit tightly with the pins of the corresponding plug to achieve power transmission; in switches, the copper parts are responsible for conducting electricity during the on-off control of the circuit. When the switch is pressed or toggled, the contact state between the copper parts changes, thereby achieving the closure (power on) or disconnection (power off) of the circuit; from a physical structure point of view, the shape of the copper parts of the switch socket varies according to its function and position in the switch socket. The socket copper parts generally include parts such as the socket and the copper strip for connection. The socket is usually an elastic structure, which can ensure that the plug pins can be tightly wrapped when the plug is inserted to ensure good contact. The connecting copper strip is mainly used to connect each socket to the power line. The switch copper parts include moving contacts and stationary contacts. The moving contacts move during operation, contacting or separating with the stationary contacts, thereby controlling the on and off of the circuit.

[0004] After searching, Chinese patent number CN117283052B discloses a cutting device for processing copper parts for switches and sockets. Although it can remove the unevenness and concave-convex structure on the surface of the copper sheet and increase the quality of the copper sheet after cutting, it cannot adapt the size of the positioning device according to the size of the socket copper parts, and the cutting and transportation of the copper parts cannot be linked, which makes the coordination requirements of the transportation and cutting of the copper parts high, and the speed of the cutter cannot be automatically adjusted according to the transmission speed of the copper parts, which easily causes the cutter to idle or overheat.

In this process, the rotation of the cutter 31 is realized by the movement of the push plate 5, so that the cutting and conveying of the copper parts used in the production of switches and sockets can be linked, so that the conveying and cutting of the copper parts can be automatically coordinated without manual calculation and regulation, and the speed of the cutter 31 can be automatically adjusted according to the conveying speed of the copper parts, that is, the faster the copper parts used in the production of switches and sockets are conveyed, the faster the speed of the cutter 31 is, thereby accelerating the cutting of the copper parts and avoiding the copper parts squeezing the cutter 31 to increase internal friction.

[0034] The working principle and use process of the present invention are as follows: when it is necessary to cut the copper parts for the production of switches and sockets, the copper parts for the production of switches and sockets are placed on the base 1, and then the limit plates 11 on both sides of the base 1 are pushed so that the side walls of the limit plates 11 are in close contact with the copper parts for the production of switches and sockets, and the positioning blocks 12 are fixed to the base 1 by bolts, thereby fixing the limit plates 11, so that the transmission track of the copper parts for the production of switches and sockets is fixed, and it is convenient for the subsequent transmission of copper parts of the same model, and in the above process, the movement of the limit plates 11 will squeeze the top plate 10, so that the top plate 10 pushes the first telescopic rod 7 and the second telescopic rod 8 into the first slide groove 6, and compresses the spring 9, so that the top plate 10, the first telescopic rod 7, the second telescopic rod 8 and the push plate 5 are always located between the limit plate 11, so that the push plate 5, the first telescopic rod 7 and the second telescopic rod 8 can encompass the ends of the copper parts for the production of switches and sockets, so as to achieve the purpose of surrounding the copper parts for the production of switches and sockets, and at the same time, it does not affect the transmission of the copper parts for the production of switches and sockets. Under the premise of being transportable, the offset sliding during the cutting of the copper parts is fully avoided, and the cutting effect of the copper parts for the production of switches and sockets is improved. At the same time, the position of the limit plate 11 can be adaptively adjusted according to the size of the copper parts, so that the position of the top plate 10 can be adaptively adjusted, which can facilitate the cutting of copper parts for the production of switches and sockets of various models; After the copper parts for the production of switches and sockets are positioned, the motor 36 is started, so that the screw rod 35 on the motor 36 drives the sliding frame 27 to move, and the other end of the sliding frame 27 is limited and guided by the guide rod 34, so that the sliding frame 27 can only move in translation, so that the sliding frame 27 drives the cutter 31 to move in translation, so that the cutter 31 can reach the specified position, and then accurately cut the copper parts for the production of switches and sockets. During the movement of the above-mentioned sliding frame 27, the second connecting plate 26 on the sliding frame 27 will drive the acceleration gear 25 to move in translation, so that the acceleration gear 25 drives the third rotating shaft 23 to extend and retract in the second rotating shaft 21, and at the same time, the second rotating shaft 21 extends and retracts in the first rotating shaft 20, and the first rotating shaft 20 limits the relative rotation of the second rotating shaft 21 through the first clamping strip 22, so that the first rotating shaft 20 and the second rotating shaft 21 rotate synchronously.

In this process, the rotation of the cutter 31 is realized by the movement of the push plate 5, so that the cutting and conveying of the copper parts used in the production of switches and sockets can be linked, so that the conveying and cutting of the copper parts can be automatically coordinated without manual calculation and regulation, and the rotation speed of the cutter 31 can be automatically adjusted according to the conveying speed of the copper parts, that is, the faster the copper parts used in the production of switches and sockets are conveyed, the faster the rotation speed of the cutter 31 is, thereby accelerating the cutting of the copper parts and avoiding the copper parts squeezing the cutter 31 to increase the internal friction. On the contrary, the conveying speed of the copper parts used in the production of switches and sockets is reduced, and the rotation speed of the cutter 31 is reduced, thereby avoiding the cutter 31 from idling, increasing energy loss, and completing the operation.
