According to an embodiment of the present invention, a production equipment for welding steel wires of soft air ducts, as shown in Figures 1-7, at least includes: a wire supply assembly, including a turntable 810 and a limit frame 820 disposed on the turntable 810; a wire output assembly , including a wire feeding assembly and a driving assembly, the driving assembly drives the wire feeding assembly to pull the wire on the limit frame 820 to unwind; the rubber strip conveying assembly includes a rotating member 840 and a pressing wheel 850, the pressing wheel 850 is used for The rubber strip unrolled on the rotating member 840 is pressed down to the upper side of the steel wire; the soft air duct conveying mechanism includes a vertical frame, a diameter adjustment assembly and a transmission assembly. The adjusting assembly includes a first tensioning assembly, a second tensioning assembly and a third tensioning assembly that can slide along the inclined hole 510, and the transmission assembly is used to drive the first tensioning assembly, the second tensioning assembly, and the second tensioning assembly. The tensioning assembly and the third tensioning assembly rotate in the circumferential direction; the welding gun 900 is used for spirally welding the steel wire sent from the wire discharging assembly between the rubber strip and the soft air duct.

The implementation of the above technical solution is basically as follows: the soft air duct is limited by the diameter adjustment component to keep the surface of the soft air duct in a stretched state, that is, there are basically no wrinkles on the surface of the soft air duct, which helps to improve processing positioning, wire supply components and wire output. The assembly transfers the steel wire to the surface of the soft air duct, and at the same time the rubber strip is transferred to the upper side of the steel wire by the pressure roller 850, and then the welding gun 900 melts the welding wire between the tape and the surface of the soft air duct, so that the steel wire can be fixed on the surface of the soft air duct , as the soft air duct is continuously rotated by the drive component, and finally a steel wire fixed on the surface of the soft air duct in a spiral shape is obtained. The overall strength of the soft air duct is improved. Compared with the prior art, which manually attaches steel wires to the soft air duct one by one, the technical solution of the present application can improve the degree of automation and production efficiency.

The embodiments of the present application include embodiments in which the first tensioning assembly, the second tensioning assembly and the third tensioning assembly are all adjustable. In order to simplify the structure, in the embodiments shown in FIGS. 1-6 , the The second tensioning assembly and the third tensioning assembly are respectively disposed on two sides of the first tensioning assembly, and the second tensioning assembly and the third tensioning assembly respond to the second air cylinder and the third air cylinder respectively Drive and slide along the inclined hole 510, the first tensioning assembly, the second tensioning assembly and the third tensioning assembly can be adjusted by adjusting the distance between the second tensioning assembly and the third tensioning assembly relative to the first tensioning assembly The size of the soft air duct that can be stretched by the three components and the degree of tension on the soft air duct.

The soft air duct in the technical solution is driven by the rotating component to continuously rotate along its own circumferential direction, and the movement on the axis of the soft air duct enables the wire to be spirally welded on the surface of the soft air duct, and the soft air duct can be manually pulled by pulling the soft air duct. The translational movement may be achieved by the translational movement of the welding torch 900 . In the embodiment shown in FIGS. 1-3 , the present application also includes a guide wheel for crimping outside the soft air duct and a limit head 830 for guiding the wire toward the welding torch 900 , the guide wheel is opposite to the soft air duct. The force exerted by the pipe has a tangential force toward one side, which promotes the translation of the soft air duct, and the limit head 830 is mainly used to limit the direction of the steel wire, and promote the steel wire to pass into the gap between the rubber strip and the soft air duct. so as to facilitate the subsequent welding and fixing work, and the position selection of the limit head 830 also has a limiting effect on the pitch of the helical steel wire. The distance between the limit head 830 and the welding torch 900 indirectly limits the occurrence of the steel wire on the soft air duct. The tightness of the spiral.

The first tensioning assembly, the second tensioning assembly and the third tensioning assembly described in the technical solution can be either integrally formed components or separate assemblies. In terms of the structure of the tensioning assembly and the third tensioning assembly, the present application includes at least two embodiments: First, the first tensioning assembly, the second tensioning assembly and the third tensioning assembly are all integrated, and only the It is necessary to sleeve the soft air duct on the first tensioning assembly, the second tensioning assembly and the third tensioning assembly, and then carry out the subsequent operations; secondly, the first tensioning assembly, the second tensioning assembly and the third tensioning assembly The three tensioning components are all separated. When processing, it is only necessary to install the soft air duct from the gap between the second tensioning component and the third tensioning component to one side. In this embodiment, the external processing components are set At a position outside the gap, the soft air duct arranged in the gap during processing can be processed, so that the processed part and the unprocessed part of the soft air duct can be well distinguished.

As shown in Figures 1-6, the latter embodiment in the previous paragraph is adopted, and the vertical frame is also set in a separate type, which specifically includes a finished side frame body 541 and a processing side frame body 542. Correspondingly, the finished side frame body 541 and the processing side frame body 542 are used. The side frame bodies 542 are provided with inclined holes 510 . Specifically, the first tensioning assembly, the second tensioning assembly and the third tensioning assembly can be separated in a manner that the first tensioning assembly includes a first support mounted on the processing side frame body 542 and the finished side frame body 541 respectively. The arm 611 and the second support arm 621, the second tension assembly includes the third support arm 641 and the fourth support arm 642 respectively installed on the processing side frame body 542 and the finished side frame body 541, and the third tension assembly includes respectively The fifth support arm 661 and the sixth support arm 662 mounted on the processing side frame body 542 and the finished product side frame body 541 . In order to facilitate the installation of the soft air duct, it is preferred in the present application that the finished side frame body 541 or the processing side frame body 542 be movable, such as sliding connection with the external frame body or the way of installing rollers, etc., before processing, so as to be the soft air duct Set in to give out the necessary space.

On the basis of the previous embodiment, in order to continuously and accurately process the soft air duct at the position that is translated to the outside of the gap, it is preferable that the ends of the first support arm 611 and the second support arm 621 are sleeved with each other, as shown in FIG. 1 . -4, on the one hand, it provides support for the processing of the soft air duct in the void part to avoid collapse and wrinkles due to the soft material of the soft air duct, which is convenient for processing and positioning. Tube is processed.

In addition, in some embodiments of the present invention, as shown in FIGS. 3 , 4 and 6 , the diameter adjustment assembly further includes a support block 680 mounted on the processing side frame body 542 , the first support arm 611 , the third support arm 641 and the The intersection lines of the fifth support arm 661 and the soft air duct are all located on the cylindrical surface of the same virtual cylinder.

It is used to strengthen the support for the soft air duct delivered to this part, which is convenient for processing and positioning.

Since the technical solution of the present application is suitable for the case where radial processing of the soft air duct is required, it can be used for processing to adjust the local strength of the soft air duct, winding steel wires on the soft air duct, and the like. When this processing requirement needs to be met, due to the addition of parts with greater strength or hardness to the finished side of the soft air duct, and the limited lengths of the first tensioning assembly, the second tensioning assembly and the third tensioning assembly, the capacity is limited. The fully extended length of the soft air duct takes up more space. Therefore, as the length of the soft air duct on the second arm 621, the fourth arm 642 and the sixth arm 662 increases, the length of the soft air duct will increase. Materials stacking occurs between them. Compared with stacking of a small amount of soft air ducts on the unmachined side, the additional strength or hardness of the machined parts makes it difficult to stack each other. Therefore, in order to save the space required for processing and to make the processed soft air ducts easy to stack, the extent to which the diameter adjustment components installed on the processing side frame 542 are adjusted to open the soft air ducts is greater than that installed on the finished product. The diameter of the side frame body 541 adjusts the extent to which the soft air ducts are opened, so as to leave a certain radial allowance for the processed soft air ducts, so as to facilitate the stacking of the processed soft air ducts. That is, the distance between the fourth arm 642 and the sixth arm 662 relative to the second arm 621 is smaller than the distance between the third arm 641 and the fifth arm 661 relative to the first arm 611 .

At the same time, since the first support arm 611 and the second support arm 621 are socketed, they can also be allowed to rotate relative to each other and have different rotational speeds.

Preferably, the rotational speed of the first servo motor 710 is smaller than the rotational speed of the second servo motor 720 on the premise that the opening degree of the processed part of the soft air duct is smaller than that of the unprocessed part of the soft air duct, thereby ensuring that the processed part of the soft air duct is The linear speed of the duct is the same as the linear speed of the unprocessed part of the soft air duct, avoiding the formation of wrinkles on the soft air duct due to the inconsistent linear speed on both sides, avoiding adverse effects on the accuracy of processing positioning, and taking into account the advantages of space saving and high precision.
