Description

Technical Field

[0001] This utility model relates to the field of hose production equipment technology, and more specifically, to a hose welding auxiliary device. Background Technology

[0002] In the production process of ultra-high pressure resin cleaning pipe, a tube core is required as a skeleton layer, and a rubber tube is formed by extrusion on the outside of it.

[0003] In actual production, many hoses have small inner diameters, requiring the use of tubing with a diameter of less than 10mm. Furthermore, most products require a length of over 40 meters. This necessitates the use of tubing in large quantities, and since it's not always possible to directly purchase tubing of the required length, tubing that doesn't meet the length requirement needs to be welded. Currently, workers place the tubing directly on the ground for butt welding. Because the tubing is thin (outer diameter less than 10mm), it's difficult to ensure complete coaxiality when butt-welding on the ground, leading to decreased welding quality. Moreover, the long alignment time required when welding two sets of tubing severely impacts production efficiency.

[0004] In summary, how to solve the problems of low coaxiality and low production efficiency in welding small-sized tubular tires is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a tubular tire welding auxiliary device, which enables rapid alignment of the tubular tire to be welded by setting at least two coaxial feeding channels in the base, ensuring coaxiality after welding, and effectively improving welding efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tubular tire welding auxiliary device includes a base with at least two sets of feeding channels inside, wherein the center lines of the two sets of feeding channels are collinear, for making the axis of the tubular tire passing through the two sets of feeding channels collinear.

[0008] The base is provided with a through operating hole, which is located at the middle position of the two sets of feeding channels extending along their own length.

[0009] Preferably, the feeding channel is a long, straight strip groove, which is a V-shaped groove or an open groove with a semi-circular bottom.

[0010] Preferably, the strip groove is formed on the surface of the base, and one end of the strip groove is connected to the operating hole.

[0011] Preferably, at least two sets of structural blocks are provided on the surface of the base, the structural blocks do not obstruct the operating hole, and the strip groove is formed on the surface of the structural blocks.

[0012] Preferably, at least two sets of structural blocks are provided on the surface of the base, the structural blocks do not obstruct the operating hole, and the feeding channel is a long, straight cylindrical channel provided within the structural blocks.

[0013] Preferably, the operating hole is a square hole or a circular hole.

[0014] Preferably, the tubular tire welding auxiliary device further includes a baffle plate, which is arranged to move relative to the operating hole. When two tubular tires enter from the two sets of feeding channels respectively, they can abut against the corresponding positions on both sides of the baffle plate, and the thickness of the baffle plate is a preset thickness.

[0015] Preferably, one end of the baffle is rotatably hinged to the surface of the base, and a shielding part is provided inside the baffle;

[0016] When the baffle is rotated to the predetermined position, the blocking part is located in the middle position of the two sets of feeding channels extending along their own length direction, and the blocking part can overlap with the projection of the two sets of feeding channels along their own center line direction.

[0017] The tubular tire welding auxiliary device provided by this utility model has at least the following advantages compared with the prior art:

[0018] The system employs at least two sets of feeding channels within the base for feeding tubular tires, ensuring that the two tubular tires passing through the feeding channels can quickly become coaxial. This effectively shortens the alignment time of the two tubular tires, improves welding efficiency, and ensures the coaxiality of the tubular tires after welding, thereby improving welding quality.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The core of this utility model is to provide a tubular tire welding auxiliary device, which enables rapid alignment of the tubular tire to be welded by setting at least two coaxial feeding channels in the base, ensuring coaxiality after welding, and effectively improving welding efficiency.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 A tubular tire welding auxiliary device includes a base 1, which has at least two sets of feeding channels 2 inside, and the center lines of the two sets of feeding channels 2 are collinear, so as to make the axis of the tubular tire passing through the two sets of feeding channels 2 collinear.

[0036] The base 1 has a through-hole 3, which is located in the middle of the two sets of feeding channels 2 extending along their own length.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, at least two sets of feeding channels 2 are provided in the base 1, and the center lines of the two sets of feeding channels 2 are collinear. Therefore, when two tubular tubes enter from the two sets of feeding channels 2 respectively, the axes of the two tubular tubes can be automatically aligned, thereby shortening the time required to align the two tubular tubes, which helps to improve welding efficiency and reduce welding costs. At the same time, since the feeding channels 2 are used for guidance, the coaxiality of the tubular tubes after welding is effectively guaranteed, and the welding quality is improved.

[0038] At the same time, such as Figure 1 and Figure 3 As shown, an operation hole 3 is also provided in the base 1. Moreover, the operation hole 3 is located in the middle of the two sets of feeding channels 2. Therefore, after the two tubes pass through the feeding channels 2, they can be connected at the position of the operation hole 3.

[0039] Users can operate the welding equipment to perform welding at the operation hole 3. Since the operation hole 3 penetrates the base 1, it is beneficial for slag removal during welding and reduces the impact of welding slag on the surface quality of the tubular material. At the same time, the operation hole 3 makes it easy for the welding equipment to approach the tubular material for welding, and it is also convenient to perform grinding operations on the welded position after welding.

[0040] In some embodiments, the feeding channel 2 is a long, straight strip groove, which is a V-shaped groove or an open groove with a semi-circular bottom.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the feeding channel 2 preferably has an open slot, which facilitates the placement and retrieval of the tubular tire. When designing the feeding channel 2, the bottom can be a semi-circular structure, which is the same as the outer circumference of the tubular tire. The radius of the bottom semi-circle is slightly larger than the radius of the tubular tire, specifically 0.5mm-1mm larger than the radius of the tubular tire. This reduces the movement allowance of the tubular tire in the feeding channel 2 and reduces the wear of the tubular tire in the feeding channel 2.

[0042] In some embodiments, the feeding channel 2 is selected as a V-shaped groove, which can adapt to the use of tubular tires of different diameters and has a good coaxiality maintenance capability.

[0043] In some embodiments, a strip groove is formed on the surface of the base 1, and one end of the strip groove is connected to the operation hole 3.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the strip groove, which serves as the feeding channel 2, is directly opened on the surface of the base 1 without the need for additional accessories. The structure is simple, easy to manufacture, and has strong stability. At the same time, since the strip groove is an open groove, the tubing can be loaded and unloaded directly from above the base 1, thereby avoiding large displacement of the tubing along its own axis within the feeding channel 2. This reduces wear on the outer wall of the tubing and helps to improve the extrusion precision of the rubber hose in the later stages.

[0045] In some embodiments, at least two sets of structural blocks 4 are provided on the surface of the base 1, the structural blocks 4 do not obstruct the operation hole 3, and the strip groove is formed on the surface of the structural block 4.

[0046] like Figure 6 and Figure 7 As shown, at least two sets of structural blocks 4 are provided on the base 1, and the strip groove serving as the feeding channel 2 is provided on the surface of the structural block 4. This allows for the replacement of structural blocks 4 to accommodate different specifications of tubular tires. Furthermore, the overall size of the structural block 4 is significantly smaller than that of the base 1, facilitating CNC machine tool processing, effectively improving processing quality and efficiency. Additionally, the welding auxiliary device can be repaired by replacing the structural block 4, thereby reducing the overall operating cost.

[0047] During the design process, a mutual locking and positioning mechanism should be provided between the base 1 and the structural block 4 to ensure a relatively stable positional relationship between the base 1 and the structural block 4, thereby ensuring that the positions of the tubular tubes in the two sets of structural blocks 4 are relatively fixed, and thus ensuring the coaxiality of the two tubular tubes.

[0048] In some embodiments, at least two sets of structural blocks 4 are provided on the surface of the base 1. The structural blocks 4 do not obstruct the operation hole 3, and the feeding channel 2 is a long straight cylindrical channel provided in the structural block 4.

[0049] like Figure 7 and Figure 8 As shown, the structural block 4 and the base 1 are designed to be detachable, and the feeding channel 2 is a long, straight cylindrical channel designed inside the structural block 4. The tubular tire can pass through the cylindrical channel. In the design, the inner diameter of the cylindrical channel should be greater than the outer diameter of the tubular tire. Specifically, the inner diameter of the cylindrical channel is equal to the outer diameter of the tubular tire plus 1mm-2mm. This ensures that the tubular tire and the base 1 have a high degree of coaxiality when the tubular tire is inside the cylindrical channel, and that there is less resistance and wear between the two when the tubular tire passes through the cylindrical channel, thus avoiding a decrease in the surface quality of the tubular tire.

[0050] In some embodiments, the operating hole 3 is a square hole or a circular hole.

[0051] like Figure 1 and Figure 5 As shown, the main function of the operating hole 3 is to suspend the welding position of the tubular tube, making it easier for the welding equipment to approach and for the welding slag to be removed. Therefore, there is no restriction on the shape of the operating hole 3. However, in actual use, the operating hole 3 is preferably a square hole of 10cm*10cm or a round hole with a diameter of 10cm-15cm, which facilitates the machining of the operating hole 3 and reduces the machining cost.

[0052] In some embodiments, the tubular tire welding auxiliary device further includes a baffle 5, which is arranged to move relative to the operating hole 3. When two tubular tires enter from the two sets of feeding channels 2 respectively, they can abut against the corresponding positions on both sides of the baffle 5 respectively, and the thickness of the baffle 5 is a preset thickness.

[0053] When welding two tubular tubes, a gap of 3.5mm-4mm must be maintained between the welding positions at the ends of the two tubular tubes, and a small welding machine with high current should be used to ensure the final welding quality.

[0054] In existing technologies, the gap between two tubular tubes is mostly adjusted manually, and its specific width is largely determined by human experience. This adjustment is time-consuming, and the gap width varies greatly, which is not conducive to ensuring the consistency of the welding effect.

[0055] Therefore, as Figure 10 and Figure 11 As shown, a movable baffle 5 is set inside the base 1. The thickness of the baffle 5 is set to the required width of the gap. When the tubular material is fed, the two tubular materials abut against the sides of the baffle 5 respectively. After the baffle 5 is removed, the gap between the two tubular materials is the thickness of the baffle 5, which is the required gap width for welding. Compared with manual adjustment, the time required is shortened and the dimensional accuracy is significantly improved, which effectively improves the welding efficiency and ensures the consistency of the welding effect.

[0056] In some embodiments, a scale is set on the base 1, and the tubular tube is adjusted manually by comparing with the scale. Although the gap size between the two tubular tubes can be made accurate, there are still problems such as long adjustment time and low welding efficiency.

[0057] In some embodiments, one end of the baffle 5 is rotatably hinged to the surface of the base 1, and a shielding part is provided inside the baffle 5;

[0058] When the baffle 5 is rotated to the predetermined position, the blocking part is located in the middle position of the two sets of feeding channels 2 extending along their own length direction, and the blocking part can overlap with the projection of the two sets of feeding channels 2 along their own center line direction.

[0059] like Figure 11 As shown, one end of the baffle 5 is rotatably hinged to the base 1. When the tubular tube is fed, the baffle 5 rotates to the first position. At this time, when the tubular tube is fixed in the feeding channel 2, its end can abut against the baffle 5 for positioning. After the tubular tube is fed, the baffle 5 is flipped to the second position to keep it away from the tubular tube, reducing interference with the welding operation of the welding equipment. Since the baffle 5 is rotatably hinged to the base 1, the baffle 5 can move to the same position each time the tubular tube is fed, that is, the welding position of the tubular tube can be positioned at the same position on the base 1 each time, which is convenient for the assembly of the welding production line and adapts to the mechanized welding of the welding robot arm.

[0060] At the same time, such as Figure 11 As shown, a blocking part is provided at the lower end of the baffle 5. When the baffle 5 is rotated to the first position, the blocking part is partially embedded in the operating hole 3 to ensure the contact area between the baffle 5 and the tubular tire, thereby ensuring the accurate positioning of the tubular tire.

[0061] In addition to the tubular tire welding auxiliary device disclosed in the above embodiments, this utility model also provides a tubular tire produced using the above-mentioned tubular tire welding auxiliary device. The tubular tire is made of several solid stainless steel columns coaxially welded together, which has better durability than existing stainless steel tube welding.

[0062] During welding, two stainless steel columns of the same diameter are placed into the two feeding channels 2 respectively, ensuring that the gap between the welding ends of the two stainless steel columns is 3.5mm-4mm. Then, the welding equipment is operated to weld the two stainless steel columns. Afterwards, the welded area is ground to obtain the tubular tube.

[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
