Description

Technical Field

[0001] The invention relates to the technical field of winding pipe production machinery, and in particular to a shaping device and a shaping and winding method for a steel wire reinforcement layer of a winding pipe. Background Art

[0002] Generally speaking, the cross section of the spiral tube is divided into three layers, which are the inner rubber layer, the reinforcement layer and the outer rubber layer from the inside to the outside. In the production field of high-pressure spiral tube, the reinforcement layer of the spiral tube is completed by the winding machine. The steel wire wound on the spiral tube must have a certain circle diameter and pitch. The circle diameter is the outer diameter of the wound tube, and the pitch is the pitch of the steel wire after the steel wire is spiraled, so as to prevent the tube from shrinking in the length direction during the vulcanization process and the wire from being fried during the stripping process of the spiral tube. When the two ends of the spiral tube are crimped, the outer rubber layer at the end is often peeled off, so that the steel wire of the reinforcement layer will be exposed. If the steel wire is not well shaped, the wire will be fried.

[0003] In the process of using the wire guide machine to put the wire on the wire wheel, it is necessary to perform plastic deformation processing on it so that the wire has a certain circle diameter and pitch, which is called pre-forming under the machine in the industry; forming requires a certain tension, and forming and wire wheel putting on the wire are completed in one link, causing the wire to suffer stress damage during the process of putting the wire on the wire wheel;

[0004] After the line is put on, the reel is installed on the turntable of the main machine. The steel wire on it must pass through the guide wheel and the front-end shaper to change its direction and then be wound onto the winding tube. In this way, the steel wire suffers secondary and tertiary stress damage. Finally, the pitch and circle diameter of the steel wire reinforcement layer after winding cannot meet the expected theoretical requirements, which reduces the compressive resistance of the winding tube and makes it impossible to control the deformation of the winding tube.

[0043] The forming ring assembly is fixedly connected to the rotating disk 2 via a forming ring connector 13 .

[0044] Specifically, through the cooperation of the wire wheel assembly and the forming ring assembly, the purpose of pre-forming the steel wire is achieved. The pitch and ring diameter of the steel wire reinforcement layer after final winding can meet the expected theoretical requirements, thereby ensuring the compressive resistance of the winding tube, controlling the deformation of the winding tube, and improving the product quality. At the same time, in the process of stripping the glue of the winding tube, the wire bursting phenomenon can be avoided, thereby ensuring the buckling quality of the winding tube.

[0045] In some embodiments, the wire wheel assembly comprises:

[0046] The wire wheel mounting block 8 is fixedly connected to one end of the wire wheel connecting rod 6, and the wire wheel 7 and the ring diameter forming wheel 9 are sequentially mounted on the wire wheel mounting block 8 for rotation along the direction of the wire 10, and the wire wheel 7 and the ring diameter forming wheel 9 are not coaxial.

[0047] Specifically, the wire wheel 7 and the ring diameter forming wheel 9 can be set at a position between the spindle 5 and the forming ring assembly by using the wire wheel connecting rod 6, so that the wire wheel 7 can play the role of a wire, that is, guiding the steel wire 10, making the steel wire 10 smoother during the wiring process, preventing the steel wire 10 from generating additional stress, and utilizing the cooperation between the ring diameter forming wheel 9 and the forming ring assembly to achieve the purpose of shaping the ring diameter of the steel wire 10; the wire wheel 7 and the ring diameter forming wheel 9 are not coaxial, which can facilitate the wire wheel 7 to guide the steel wire 10, and at the same time, the ring diameter forming wheel 9 and the forming ring assembly can better cooperate to achieve the purpose of shaping the ring diameter of the steel wire 10.

[0049] Specifically, Figure 2 As shown, the adapter ring 14 is a circular ring structure, and the other end of the wire wheel connecting rod 6 is fixedly connected to the adapter ring 14. The wire wheel connecting rod 6 mainly serves to connect the adapter ring 14 to the rotating disk 2. Therefore, the number of wire wheel connecting rods 6 is greater than or equal to two. Multiple wire wheel mounting blocks 8 can be evenly distributed on the circumference of the adapter ring 14, thereby achieving the purpose of guiding and shaping the ring diameter of multiple strands of steel wires 10. The wire wheel mounting blocks 8, the ring diameter forming wheel 9 and the wire wheel 7 correspond one by one to the bobbin 4 and the spindle 5.

[0050] In some embodiments, the ring diameter forming wheel 9 includes a mounting portion 901, and a plurality of ring diameter forming portions 902 that are coaxial with and integrally formed with the mounting portion 901, a baffle 903 is provided between the plurality of ring diameter forming portions 902, the diameters of the plurality of ring diameter forming portions 902 are not equal, and the mounting portion 901 is rotatably matched with the wire passing wheel mounting block 8.

[0051] Specifically, for steel wires 10 of different wire diameters, the degree of deformation difficulty is different, so the ring diameter forming wheel 9 is required to have ring diameter forming parts 902 of different diameters. The steel wire 10 passes through different ring diameter forming parts 902 and cooperates with the ring diameter forming wheel 9 and the wire passing wheel assembly to achieve the purpose of forming the steel wire 10 into different ring diameters; the mounting part 901 rotates with the wire passing wheel mounting block 8, and the ring diameter forming wheel 9 rotates with the steel wire 10, which can reduce the friction of the steel wire 10 as much as possible, thereby ensuring the quality of the winding tube 1; a baffle 903 is provided to enable the steel wire 10 to move in a given ring diameter forming part 902 to prevent it from entering the ring diameter forming part 902 of other diameters, thereby ensuring the forming quality of the steel wire 10.

[0052] In some embodiments, the forming ring assembly comprises:

[0053] A forming ring 11, wherein the forming ring 11 is fixedly connected to one end of the forming ring connector 13, and the inner ring of the forming ring 11 has a wire running space;

[0054] An adjusting ring 12, which is installed on the outer periphery of the forming ring connector 13 so as to be able to adjust the position axially;

[0055] The interior of the forming ring connector 13 is a space for the winding tube to travel.

[0056] Specifically, the adjusting ring 12 is installed on the outer periphery of the forming ring connector 13 so as to be able to adjust the position axially, that is, the adjusting ring 12 is fixedly installed on the outer periphery of the forming ring connector 13, and the adjusting ring 12 can be adjusted along the axial position. Specifically, the inner ring of the adjusting ring 12 and the outer periphery of the forming ring connector 13 can be matched by threads, or a screw connection plate can be used to adjust the axial position and achieve relative fixation after the position adjustment. In this embodiment, the inner ring of the adjusting ring 12 and the outer periphery of the forming ring connector 13 are matched by threads; please refer to Figure 1 and Figure 2 By adjusting the axial position of the adjusting ring 12, the horizontal relative position of the adjusting ring 12 and the circle diameter forming wheel 9 can be adjusted, so that the steel wire 10 will generate a large stress when passing through the circle diameter forming wheel 9 and the adjusting ring 12, thereby achieving the purpose of forming the diameter of the steel wire circle; at the same time, the cooperation of the adjusting ring 12 and the forming ring 11 will cause the corresponding pitch to be generated through the adjusting ring 12 and the forming ring 11, such as, when the adjusting ring 12 moves to the right, the circle diameter formed by the steel wire is small and the pitch is small, and when the adjusting ring moves to the left, the circle diameter formed by the steel wire is large and the pitch is large. Through the cooperation of the circle diameter forming wheel 9, the adjusting ring 12 and the forming ring 11, the purpose of matching winding of winding tubes with different diameters is achieved; in specific work, the traction machine is used to pull The winding tube 1 is guided to move axially along the winding tube walking space inside the forming ring connector 13, and the motor drives the rotating disk 2 to rotate, and then the spool 4 and spindle 5, multiple wire wheel assemblies and forming ring assemblies mounted on the hanging column 3 will rotate accordingly, and the steel wire 10 is wound on the winding tube. Due to the cooperation of the ring diameter forming wheel 9, the adjustment ring 12 and the forming ring 11, the steel wire 10 can be shaped in advance, and the pitch and ring diameter of the steel wire reinforcement layer after final winding can meet the expected theoretical requirements, thereby ensuring the compressive resistance of the winding tube, controlling the deformation of the winding tube, and improving the product quality; at the same time, in the process of stripping the glue of the winding tube, the wire frying phenomenon can be avoided, thereby ensuring the buckling quality of the winding tube.

[0057] In some embodiments, the contact surfaces of the forming ring 11 and the adjusting ring 12 with the steel wire 10 are arc surfaces.

[0058] Specifically, this can prevent the steel wire 10 from being scratched during the running process, thereby ensuring the winding quality of the winding tube.

[0059] In some embodiments, the molded ring connector 13 includes:

[0060] A bearing seat 1303, wherein the bearing seat 1303 is fixedly connected to the rotating disk 2;

[0061] The forming ring adapter 1301 is fixedly connected to one end of the bearing seat 1303 through a forming ring connecting rod 1302. The forming ring adapter 1301 has an external thread. The forming ring adapter 1301 and the adjusting ring 12 are threadedly matched through the external thread. The forming ring 11 is fixedly connected to the forming ring adapter 1301.

[0062] Specifically, the bearing seat 1303 is provided to ensure the normal rotation of the rotating disk 2, and to ensure that the winding tube 1 can be pulled by the external traction machine at the axis of the rotating disk 2, and each action can be independent and coordinated; the present disclosure takes the forming ring adapter 1301 and the adjusting ring 12 as an embodiment through the external thread thread cooperation, so that the adjusting ring 12 is fixedly installed on the forming ring adapter 1301, and the purpose of axial movement of the adjusting ring 12 along the forming ring adapter 1301 can be realized.

[0063] In some embodiments, the molding ring assembly further includes an adjustment ring positioning device for preventing the adjustment ring 12 from axially moving, and the number of the adjustment ring positioning devices is greater than or equal to two and is evenly distributed around the circumference.

[0064] In some embodiments, the adjusting ring positioning device comprises:

[0065] A positioning seat 16, wherein the positioning seat 16 is fixedly connected to the forming ring adapter 1301;

[0066] The positioning screw 15 is threadably matched with the positioning seat 16 . When in operation, the end surface of the positioning screw 15 fits with the end surface of the adjusting ring 12 .

[0067] Specifically, the number of the adjustment ring positioning devices is greater than or equal to two and is evenly distributed around the circumference. This can prevent the adjustment ring 12 from axially moving and from tilting, thereby ultimately ensuring the quality of the pre-forming of the steel wire. This can be achieved by pressing the end face of the adjustment ring 12 with the positioning screw 15.

[0068] A shaping and winding method for a steel wire reinforcement layer of a winding tube:

[0069] The first step is to put a spool 4 with a strand of steel wire on the wire hanging column 3 of the rotating disk 2, wherein the number of strands of steel wire is greater than or equal to one, and then install a spindle 5 at the end of the wire hanging column 3;

[0070] The second step is to adjust the lateral position of the adjusting ring 12 relative to the ring diameter forming wheel 9, and use the positioning screw 15 to press the end surface of the adjusting ring 12 to achieve the purpose of limiting the axial movement of the adjusting ring 12;

[0071] The third step is to thread the steel wire 10, and pass the steel wire 10 on the spool 4 through the spindle 5, the wire wheel 7, the ring diameter forming wheel 9, the outer ring of the adjustment ring 12 and the wire running space of the forming ring 11 in turn, so as to achieve the purpose of shaping the steel wire reinforcement layer of the winding tube.

[0072] Specifically, the spool 4 is the spool for winding the steel wire during normal operation. The difference is that the spool of the present invention is wound with multiple steel wires, that is, the number of steel wires is greater than or equal to one, that is, the shaping and winding of the steel wire reinforcement layer of the present invention are applicable to both a single steel wire and multiple steel wires (one strand). More than two steel wires are combined into one steel wire, and then the winding tube is wound. The spindle 5 is the spindle with application number: CN201921851642.7, which plays a role in controlling the tension of the steel wire; after the adjustment ring 12 is adjusted, the positioning screw 15 is used to position the adjustment ring 12, and then the steel wire is threaded. The principle is as follows Figure 1 The steel wire orientation shown in the figure finally achieves the purpose of preforming the steel wire on the machine, that is, the purpose of shaping the steel wire reinforcement layer of the winding tube is achieved;

[0073] During the process of winding the high-pressure pipe, the middle reinforcement layer is completed by the winding machine. At present, the mainstream winding machine in China is used in the process of installing the reel wound with a single steel wire on the turntable of the main machine, and determining the number of reels according to the outer diameter of the winding pipe; due to the invariance of the principle of the winding balance angle of 54°44′ and the limitation on the number of spools 4 installed on the turntable of the winding machine main machine, the outer diameter of the hose wound by the main machine is subject to certain restrictions; since a single steel wire is wound on each spool 4, in order to produce a large-diameter winding pipe, the outer diameter of the turntable of the main machine can only be increased, thereby increasing the number of spools 4. In this way, the removal and installation of the spools 4 on the large disk require a lot of time and energy, which seriously affects the production efficiency of the product;

[0074] Therefore, the shaping and winding method of the steel wire reinforcement layer of the winding tube disclosed in the present invention uses a method of winding multiple steel wires at the same time. The number of hundreds of wire wheels on the original winding machine can be reduced by more than 4-6 times, which greatly improves the replacement speed of the wire wheels and improves work efficiency.
