Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention,

referring to fig. 1-5 of the drawings,

the wire cutting mechanism Z can be arranged between the upper winding device X and the lower winding device Y, the layout can save the space of the whole winding device, and the miniaturization development of the device is facilitated; because the wire cutting mechanism is arranged between the upper winding device and the lower winding device, the wire rod can pass through the wire cutting mechanism, and the wire cutting mechanism is provided with a plurality of wire feeding joints 7 for outputting the wire rod;

firstly, a wire rod is fed into a winding device through a wire feeding device through a wire cutting mechanism, then a coil is formed through processing of the winding device, when the wire winding device works, a guide rod 4 is driven to move along the direction of a guide groove 31 through a driving device 5, namely, a cutting assembly 2 is enabled to approach to the direction of a wire feeding joint 7, and the wire rod can be cut off after the wire rod reaches a certain position, so that the cutting assembly 2 is small in action and rapid, and the production efficiency can be effectively improved;

in order to make the action of the cutting assembly 2 smooth and stable, a sliding pair 6 is arranged between the mounting plate 3 and the cutting assembly 2.

In this embodiment, the guide groove 31 extends toward the first fixing seat 1, that is, the guide groove 31 extends downward, and the cutting assembly 2 cuts off the wire rod from top to bottom under the driving of the driving device 5.

In this embodiment, the driving device 5 includes the first cylinder 51 and the push block 52, so that the structure of the driving device 5 is extremely simplified, the first cylinder 51 is transversely installed on the mounting plate 3, and the position outside the cutting mechanism is not occupied, the space is saved, when the device works, the first cylinder 51 transversely pushes the push block 52 to act, but the guide groove 31 limits the transverse movement of the guide pillar, under the action of the guide hole 53 which is obliquely arranged, the guide pillar can also move downwards along the guide groove 31, the whole design is simplified through simple and ingenious design, and compared with the existing driving device 5, the device is smaller in size and higher in efficiency.

In yet another aspect, the cutting mechanism may block some parts due to the complicated structure of the winding machine, so the utility model adopts the vertical left and right action mode to avoid some parts to achieve the purpose of avoiding the position.

In the embodiment, the cutter 22 is designed in an L shape, and the position of the cutter 22 in a normal state does not correspond to the position of the wire feeding connector 7, but is positioned above a vacant position between the two wire feeding connectors 7, so that the cutter 22 can be prevented from interfering other parts, when cutting, the driving device 5 is used for descending the fixed seat two 21, namely, the cutter 22 is used for moving downwards and is positioned in the vacant position between the two wire feeding connectors 7, each cutter 22 corresponds to the wire feeding connector 7, then the air cylinder two 214 is used for pushing the connecting plate two 212 to move along the sliding pair two 213, namely, the cutter 22 is used for moving transversely to approach the wire feeding connector 7 to cut off the wire, and finally the air cylinder two 214 and the driving device 5 are used for resetting the cutter 22, and the cycle is repeated.

The wire is stretched and tightened during winding and processing, and the wire contracts after cutting, so that the wire feeding is difficult in subsequent production, a wire pressing device 8 is arranged on the fixed seat, and before the wire is cut, the wire is pressed tightly through the wire pressing device 8 to keep tension, so that the wire feeding in subsequent processing is facilitated;

more specifically, the wire is placed between the wire feeding connectors 7 and can pass through the wire placing groove 84 on the fixing frame 81, the pressing block 83 is pressed on the wire placing groove 84 through the pressing component 82, pressure is continuously applied to compress the wire, then the wire is cut through the cutter 22, and the wire is compressed at the moment and cannot shrink, so that subsequent wire feeding processing is facilitated.

Still need continue to carry the wire rod after the wire rod is compressed tightly, but still can not loosen the wire rod in transportation process, through setting up the vice three 85 of slip, make mount 81 and fixing base can carry out relative slip, still cooperate propelling movement subassembly 86 in addition, make mount 81 can follow the vice three 85 directions of slip and move, namely move to wire feeding joint 7 direction, the wire rod still is pushed down this moment, the wire rod alright follow wire feeding joint 7 and stretch out, is pressed from both sides tightly by winding device again, carries out coil processing.
