Description

Technical Field

[0001] The utility model relates to the field of wire winding machine equipment, in particular to a wire drawing power wheel frame of a wire winding machine. Background Art

[0002] Tungsten wire rope winding machine is a kind of mechanical equipment specially used for winding and producing tungsten wire rope. It winds tungsten wire into strands through the anti-wire winding machine frame structure to form the required tungsten wire rope. During the working process of the winding machine, due to the tension of the winding metal wire such as tungsten wire rope, the finished tungsten wire rope needs to be wound on the drawing wheel with annular grooves during the winding process. The metal wire is tightened and rotated and pulled by two sets of parallel drawing wheels to guide the finished tungsten wire rope to the winding position. However, the current winding machine fixes the drawing wheel on the axle by bolts, and multiple sets of bolts need to be set around the axle to achieve stable installation of the drawing wheel. Since the tungsten wire rope is supported by the burning of the metal wire, the winding groove of the drawing wheel is easy to wear after long-term use, and the drawing wheel as the traction power wheel needs to be replaced regularly. However, the current installation structure using bolts as fasteners is cumbersome to disassemble and assemble, and inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to provide a wire drawing power wheel frame for a wire winding machine in order to solve the above-mentioned problem. By arranging two groups of retaining frames that can extend outward in the middle of the wheel axle, the retaining frames are moved out to abut against the end face of the drawing wheel, thereby realizing rapid positioning of the drawing wheel and improving the convenience of disassembly and assembly of the drawing wheel; and arranging a synchronous frame to connect the two groups of wheel axles for transmission, ensuring that the two groups of wheel axles can rotate at the same speed through a synchronous belt, avoiding the tungsten wire rope from being damaged due to inconsistent rotation speeds of the two groups of drawing wheels, and making it safer to use. See the following description for details.

Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0028] See also Figure 1-Figure 7 As shown, the utility model provides a wire drawing power wheel frame of a wire winding machine, comprising a machine body 1 and two sets of wire drawing wheels 2, the two sets of wire drawing wheels 2 are arranged in parallel in front of the machine body 1, and two sets of wheel axles 3 supporting the rotation of the wire drawing wheels 2 are arranged in the middle of the machine body 1, a power component (not shown in the figure) driving the wheel axle 3 to rotate is built into the machine body 1, a retaining frame 4 is arranged in the middle of the wheel axle 3, and a positioning screw 5 extending to the front end surface of the wire drawing wheel 2 is threadedly matched with the front end of the wheel axle 3 to push the retaining frame 4;

[0029] A receiving groove 302 for accommodating the retaining frame 4 is vertically penetrated through the middle of the wheel axle 3. The retaining frame 4 includes a locking plate 401 that vertically slides and fits the receiving groove 302. The locking plate 401 extends into the receiving groove 302 and is fixed with a constraint plate 402 that extends outwardly and is inclined. The end of the positioning screw 5 is fixed with a conical head 501 that extends into the receiving groove 302 between two adjacent groups of retaining frames 4. The outer side of the conical head 501 is tightly pressed against the outer surface of the constraint plate 402 to ensure that the conical head 501 can push the two groups of retaining frames 4 to extend outward, thereby realizing the limit locking of the retaining frame 4 on the drawing wheel 2.

[0030] As an optional embodiment, a rotating seat 101 supporting the rotation of the wheel shaft 3 is fixed on the front side of the machine body 1, and a limiting ring 301 is coaxially fixed to the outside of the wheel shaft 3 in front of the rotating seat 101, and the front side of the limiting ring 301 abuts against the rear side of the drawing wheel 2, so as to use the limiting ring 301 to position the rear side of the drawing wheel 2;

[0031] A rotating ring 201 sleeved on the outside of the wheel axle 3 is coaxially fixed to the middle of the wire drawing wheel 2, and a locking groove 202 for receiving and inserting a locking plate 401 is vertically penetrated on the front side of the rotating ring 201, and then the locking plate 401 is used to cooperate with the locking groove 202 to realize the rotation transmission of the wire drawing wheel 2 and the wheel axle 3. An annular groove-shaped wire winding groove 203 is arranged on the outside of the wire drawing wheel 2, and a connecting piece 403 is fixed on the front side of the constraint plate 402. A limiting ear 304 is arranged at the outer opening of the receiving groove 302 corresponding to the connecting piece 403, and a support rod 404 vertically penetrating the limiting ear 304 is fixed on the outside of the connecting piece 403. The support rod 404 is matched with the limiting ear 304 to ensure that the retaining frame 4 as a whole can slide along the receiving groove 302 under the support of the limiting ear 304.

[0032] A spring 405 is sleeved on the outside of the support rod 404 between the limiting ear 304 and the connecting piece 403. The compression stroke of the spring 405 is greater than the length of the support rod 404 extending out of the limiting ear 304. The connecting piece 403 is pushed by the spring 405. When the conical head 501 escapes from the receiving groove 302, the connecting piece 403 can be pushed by the spring 405 to receive the locking piece 401 into the receiving groove 302, so that the locking piece 401 automatically releases the supporting and limiting state of the wire drawing wheel 2. The outer end of the positioning screw 5 is fixed with a knob 502 that is pressed against the front end surface of the wheel shaft 3. The diameter of the knob 502 is greater than the outer diameter of the wheel shaft 3, and the front end of the wheel shaft 3 is provided with a regular polygonal transmission groove 303.

A rotating drum 603 is rotatably matched with the mounting ring 602 through a bearing. A transmission hole 604 is penetrated in the middle of the rotating drum 603 and is sleeved on the outside of the transmission groove 303. The transmission hole 604 is a regular polygonal through hole adapted to the shape of the transmission groove 303.

A pulley 605 is fixed to the rear end of the rotating drum 603. The outer sides of the two groups of pulleys 605 are connected with synchronous belts 606 for transmission. The two groups of rotating drums 603 and the two groups of wheel axles 3 are rotated synchronously through the synchronous belt 606, thereby ensuring that the rotation speeds of the two groups of drawing wheels 2 are consistent, and avoiding the tungsten wire rope being damaged due to the difference in rotation speeds of the two groups of drawing wheels 2.

[0034] With the above structure, when the drawing wheel 2 needs to be removed, the knob 502 corresponding to the position of the drawing wheel 2 is rotated to rotate the positioning screw 5 forward, thereby releasing the tightening effect of the conical head 501 at the rear end of the positioning screw 5 on the inclined state constraint plate 402, so that the spring 405 pushes the connecting piece 403 to drive the constraint plate 402 and the locking piece 401 to be received in the accommodating groove 302, thereby releasing the clamping support effect of the locking piece 401 and the locking groove 202, and at this time, the positioning screw 5 is rotated forward to disengage from the wheel The synchronous frame 6 and the wire drawing wheel 2 can be separated from the wheel axle 3 to realize the rapid disassembly of the wheel axle 3. The replaced wire drawing wheel 2 is subsequently sleeved on the outside of the wheel axle 3 and pressed against the limit ring 301 to reset the synchronous frame 6. Then the positioning screw 5 is rotated to extend into the receiving groove 302, and the two sets of retaining frames 4 in the receiving groove 302 are pushed out in the opposite direction by the conical head 501. The locking piece 401 is again inserted into the locking groove 202 to complete the positioning of the wire drawing wheel 2 and the transmission connection with the wheel axle 3.

[0035] By arranging two groups of retainers 4 that can extend outward in the middle of the wheel shaft 3, after the wire drawing wheel 2 is placed in place on the wheel shaft 3, the two groups of retainers 4 can be pushed outward by the positioning screw 5, so that the retainers 4 are moved out to abut against the end surface of the wire drawing wheel 2, thereby realizing the rapid positioning of the wire drawing wheel 2 and improving the convenience of disassembly and assembly of the wire drawing wheel 2;

[0036] A synchronous frame 6 is provided to connect the two sets of axles 3 for transmission, ensuring that the two sets of axles 3 can rotate at the same speed through the synchronous belt 606, avoiding the tungsten wire rope being damaged due to the inconsistent rotation speed of the two sets of drawing wheels 2, and making it safer to use.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
