Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of multi-head wire drawing production, and in particular to an automatic wire changing system of a multi-head wire drawing machine. BACKGROUND

[0002] The wire drawing machine is mainly used for the production and processing of metal wire products, and through wire drawing and wire drawing processing, the diameter, roundness, internal metallographic structure, surface finish and straightness of the wire can all meet the specified standards. The wire feeding system is the source on which the production line works and is one of the most important components of the wire drawing production line. The wire feeding system usually adopts a basket type wire feeding, that is, the wire feeding guide wheel assembly is first fixed above the wire basket, and then the wire in the wire basket passes through the wire feeding guide wheel assembly and enters the wire drawing machine.

[0003] In order to optimize the wire changing in the wire feeding system, a kind of inductive automatic wire changing system for multi-head wire drawing machine is disclosed in Chinese patent CN 109692886B, which comprises a wire feeding basket and a movable wire feeding assembly. The movable wire feeding assembly comprises a horizontal guide rail fixed on a wire feeding support, and the guide direction of the horizontal guide rail is parallel to the arrangement direction of the two groups of wire feeding baskets below the horizontal guide rail. A movable hoist arm is arranged on the horizontal guide rail and cooperates with the horizontal guide rail to form a slider guide rail. A deflection wheel for changing the running direction of the wire in the wire feeding basket is arranged on the movable hoist arm. Through induction, automatic wire changing operation is performed.

[0004] For the above prior art, although automatic wire changing operation can be performed, the multi-head wire drawing machine is equipped with more than one wire feeding basket. Due to the different distances of the multiple wire feeding baskets, the number of replaceable wire feeding baskets in a single group is different. Under the superposition of the above factors, when the wires in the single wire feeding basket are consumed at different speeds, the order of the wire feeding baskets is different, which requires workers to observe the consumption of different wire feeding baskets in a time period, so as to supplement the replaced wire feeding baskets to prevent the new wire feeding baskets from being consumed before being replaced in time. However, the above operation still requires workers to monitor, and only when all the replaced wire feeding baskets are empty can the replacement be performed, so as not to cause additional waiting time. Therefore, how to synchronize the consumption of wires in the wire feeding baskets and replace the wires simultaneously is a technical problem to be solved in order to concentrate the wire supplement time, reduce the work burden of workers and reduce unnecessary working time loss.

[0037] The preferred embodiments of the present application will be described in detail below with reference to the drawings, wherein the drawings constitute a part of this application and illustrate the principles of the present application together with the embodiments thereof, but are not intended to limit the scope of the present application.

[0038] As Figures 1-2As shown, the present application provides an automatic wire changing system of a multi-head wire drawing machine, which comprises a driving mechanism 1, a driven gear 101 and a traction mechanism 2. A plurality of the driven gears 101 are sequentially engaged, the driving mechanism 1 is used to drive the rotation of the driven gear 101 at one end, and the driven gears 101 are sequentially driven and simultaneously rotated, the top of the driven gear 101 is provided with a disc body 3 with the same center, a plurality of wire baskets 4 are circumferentially arranged on one disc body 3, the wire basket 4 is used to internally place the wire, under the rotation of the driven gear 101, the disc body 3 is driven to rotate, the wire basket 4 thereon can be transposed, and all the wire baskets 4 on the same wire are synchronously transposed, the transmission structure is simple, the effect is obvious, and the transposition efficiency is high, and the fault is easy to detect. The traction mechanism 2 is arranged above the disc body 3, and a plurality of traction ends are arranged on the traction mechanism 2, the traction ends are respectively located directly above the disc body 3, and the area directly below the traction ends is a working position 201, the traction mechanism 2 is used to synchronously pull and consume the wire in the initial wire basket 4 in the working position 201, when the wire in the initial wire basket 4 is synchronously consumed, the wire in the subsequently replaced wire basket 4 is synchronously replaced, so that the wire is also synchronously consumed under the synchronous feeding speed. Therefore, the consumption time is the same each time, and the time of replacing the wire basket 4 is also the same each time under this condition.

[0039] It can be understood that the number of driven gears 101 is arranged according to the number of wire basket 4 groups required, as long as they are sequentially engaged, and the driven gear 101 at one end is driven to rotate.

[0040] Embodiment one

[0041] In order to arrange the wire basket 4 groups in a row, in this embodiment, referring to Figures 1-3 , the traction mechanism 2 comprises a strip-shaped plate 21 and a first traction wheel group 22, a plurality of the traction wheel groups 22 are sequentially arranged along the length direction of the strip-shaped plate 21 from right to left, used to pull the wire to the strip-shaped plate 21 and convey the wire along the strip-shaped plate 21 to the right, and the right side of the strip-shaped plate 21 is provided with a reversing roller 2101, used to reversely guide the wire downward, the wire is pulled upward from the wire basket 4, passes through the first traction wheel group 22, is pulled to the reversing roller 2101 and moves downward.

[0042] It can be understood that the first traction wheel group 22 has two functions, one is to convey the wire, and the other is to convert the vertically upward feeding wire into horizontal movement on the strip-shaped plate 21, so as to be reversely guided to downward convey at the reversing roller 2101.

[0043] Further, since the arrangement of the wire bobbins 4 is in a column, that is, once arranged from right to left along the length direction of the strip plate 21, when the wire bobbins 4 are in the feeding direction of the rightmost side, the nearest initial wire bobbin 4 is closest to the rightmost side, and the movement of the wire bobbin 4 to the rightmost side consumes the least amount of wire, and the other wire bobbins 4 are sequentially increased from right to left, therefore, the time for the initial wire bobbin 4 to be consumed is different, in order to offset the difference in initial consumption, the traction mechanism 2 further comprises an extension wire 23, the extension wire 23 is slidingly connected in the traction wheel set 22, and the bottom end thereof passes through the wire inlet end of the traction wheel set 22 and extends downward by the same length to the working position 201, for docking to the end of the wire in the initial wire bobbin 4, the other end of the extension wire 23 passes through the traction wheel set 22 and extends to the reversing roller 2101, the extension wire 23 balances the wire consumption of each initial wire bobbin 4, so that the wire consumed between the reversing rollers 2101 is consumed by the extension wire 23, and therefore the wire in the wire bobbin 4 itself is not consumed, thereby ensuring that the wire in the wire bobbin 4 can be consumed synchronously and simultaneously replaced.

[0044] It can be understood that the several wire bobbins 4 in the same group are connected in sequence according to the rotation and replacement of the wire, and when the replacement is performed, the connection can be smoothly connected.

[0045] Further, the first traction wheel set 22 comprises a first stress wheel 221, a first reversing wheel 222 and a second reversing wheel 223, the first stress wheel 221 and the first reversing wheel 222 are both vertically rotatably connected on one side of the strip plate 21, and the second reversing wheel 223 is horizontally rotatably connected on the top of the strip plate 21, the wire passes through the first stress wheel 221 in traction, is changed from vertical to horizontal by the first reversing wheel 222, and is changed to move to the right by the second reversing wheel 223.

[0046] Embodiment two

[0047] In order not to use the extension wire 23 directly for feeding, in this embodiment, referring to Figure 6The traction mechanism 2 includes a disc-shaped top plate 24 and a second traction wheel set 25 which is circumferentially arranged on the disc-shaped top plate 24, and a circular hole 2401 is arranged at the center of the disc-shaped top plate 24. The second traction wheel set 25 is used for directly upwardly drawing the wire and downwardly conveying the wire through the circular hole 2401. Since the second traction wheel set 25 is circumferentially arranged, the driven gears 101 are also circumferentially arranged. Under the driving of the driving mechanism 1, the driven gears 101 are also simultaneously rotated, the wire basket 4 can be transposed and the wire can be changed, and since the distance between each working position 201 and the circular hole 2401 is the same, the wire can be directly drawn, the consumption difference is small, the purpose of synchronous consumption can be basically achieved, and the automatic wire changing system is suitable for the case that the length direction space of the warehouse is small and the width direction space is sufficient, and the extended wire 23 does not need to be connected, and the use is more convenient.

[0048] Further, the second traction wheel set 25 includes a second stress wheel 251, a third reversing wheel 252 and a fourth reversing wheel 253. The second stress wheel 251 and the third reversing wheel 252 are vertically rotatably connected to the outside of the disc-shaped top plate 24, and the fourth reversing wheel 253 is vertically rotatably connected to the inside of the circular hole 2401. In the wire drawing process, the wire is drawn upwardly by the second stress wheel 251, changed to be horizontal by the third reversing wheel 252, and changed to be downward by the fourth reversing wheel 253, and then fed downwardly through the circular hole 2401.

[0049] In any embodiment, referring to Figure 1 and Figure 6 , in order to support each component, the automatic wire changing system further includes a bottom plate 5, and the traction mechanism 2 is mounted on the bottom plate 5 through a support, so that the traction end is suspended directly above the wire basket 4, and the bottom plate 5 is further provided with a wire arranging roller 501 for horizontally arranging the wire output by the traction mechanism 2, and the wire re-conveyed downwardly by the traction mechanism 2 is arranged in a row and conveyed to the subsequent multi-wire drawing through the wire arranging roller 501.

[0051] In any embodiment, referring to Figure 1In order to have intelligent control effect, the automatic wire changing system further comprises a time switch 6, which is electrically connected to the driving mechanism 1 and is used to time the position changing of the wire feeding basket 4. Since the wire feeding baskets 4 in each group are exhausted synchronously in the working position 201, the time required for each exhaustion can be calculated according to the feeding speed of the multi-wire drawing and the wire length in each wire feeding basket 4. According to the time, the time switch 6 is simply set to control the driving mechanism 1 to be turned on at intervals and to drive the corresponding angle, so that the position changing effect of the wire feeding basket 4 can be achieved, and after each position changing, the wire feeding basket 4 in use is located in a good position for wire feeding, i.e. the working position 201. No additional sensor unit is required, the overall intelligent control structure is simple, the cost is low, and the maintenance and repair are easy.

[0052] In any embodiment, referring to Figure 1 In order to achieve the driving effect of the driven gear 101, the driving mechanism 1 comprises a driving motor 11 and a driving gear 12, the driving gear 12 is arranged on the output shaft of the driving motor 11, and the driving gear 12 is engaged with the driven gear 101 at one end. The driving motor 11 drives the driving gear 12 to rotate, and the driving gear 12 drives the driven gear 101 engaged therewith, thereby achieving the driving effect.

[0053] It can be understood that the driving motor 11 is fixed on the bottom plate 5 by a support, and the driving gear 12 and the driven gear 101 are also rotatably connected to the top of the bottom plate 5.

[0054] The specific working process of the present application is as follows: when the wire feeding baskets 4 are arranged in a row, the extended wire 23 is sequentially threaded through the first stress wheel 221, the first reversing wheel 222 and the second reversing wheel 223, and then is pulled to the reversing roller 2101 and then to the wire arranging roller 501, and finally the bottom end of the extended wire 23 is connected to the end of the wire in the initial wire feeding basket 4 in the working position 201; when the wire feeding baskets 4 are arranged in a circle, the wire is sequentially threaded through the second stress wheel 251, the third reversing wheel 252 and the fourth reversing wheel 253, and then is pulled to the wire arranging roller 501; when the wire in the wire feeding basket 4 is exhausted, the time switch 6 drives the driving motor 11 to drive the driving gear 12 to rotate, the driving gear 12 drives the driven gear 101 at one end to rotate, the multiple driven gears 101 rotate in turn, and then the disc body 3 rotates correspondingly, so that the wire feeding basket 4 is changed in position, and the wire feeding basket 4 in the working position 201 is replaced to a better position for wire feeding.
