[0052] A specific embodiment of the present invention provides a forming machine for a large-diameter oil transmission rubber hose with a length of 100 meters, which includes a first driving device 1, a second driving device 9, and a support frame 10. The first driving device 1 and the second driving device 9 are respectively arranged on both sides of the support frame 10;

[0053] The support frame 10 is detachably spliced by a plurality of rectangular frames. A bracket is arranged above the support frame 10, and the bracket is used to support the tube core;

[0054] Such as Figure 1 And 2 As shown, the tube core is supported by the bracket on the support frame 10. The two ends of the tube core are clamped by the first driving device 1 and the second driving device 9, and the tube core is driven to rotate by the first driving motor 106 to solve the problem of twisting when the ultra-long rubber hose rotates. The support frame 10 adopts a modular design and is formed by splicing a plurality of rectangular frames, and the number of modules can be increased or decreased according to the length of the tube core.

[0055] The bracket includes a plurality of powered brackets 2 and a plurality of unpowered brackets 3;

[0056] The powered brackets 2 and the unpowered brackets 3 are alternately arranged on the rectangular frames of the support frame 10;

[0057] The powered bracket 2 includes a first bracket seat 21. The first bracket seat 21 is installed on the support frame 10. A first elevator 22 is installed at the lower end of the first bracket seat 21. The first elevator 22 is fixed to the lower end of the support frame 10. A second double-sided rack 23 is installed on the driving end of the first elevator 22. The front and rear ends of the second double-sided rack 23 are meshed and connected with second gears 24. The second gears 24 are rotatably installed in the first bracket seat 21. A first swing arm 25 is installed at the upper end of the second gear 24. A first roller 26 is rotatably installed at the end of the first swing arm 25 away from the second gear 24. First sprockets 27 are rotatably installed at the upper and lower ends of the side wall surface of the first swing arm 25. The upper first sprocket 27 is fixedly connected with the first roller 26. A first chain 28 is connected between the upper and lower corresponding first sprockets 27. A double-shaft motor 29 is installed at the front end of the first bracket seat 21. Second sprockets 30 are installed at both ends of the double-shaft motor 29. The second sprockets 30 are respectively connected with the lower first sprockets 27 through second chains 301;

[0058] The unpowered bracket 3 includes a second bracket seat 31. The second bracket seat 31 is installed on the support frame 10. A second elevator 32 is installed at the lower end of the second bracket seat 31. The second elevator 32 is fixed to the lower end of the support frame 10. A third double-sided rack 33 is installed on the driving end of the second elevator 32. The front and rear ends of the third double-sided rack 33 are meshed and connected with third gears 34.

[0059] As Figures 5 - 10 shown, the first elevator 22 can drive the second double-sided rack 23 to move up and down. When the second double-sided rack 23 moves up and down, it can drive the second gear 24 to rotate. When the second double-sided rack 23 rises, the first roller 26 rises; when the second double-sided rack 23 descends, the first roller 26 descends. When a pair of first rollers 26 descends, it can support a pipe diameter with a larger diameter. On the contrary, when a pair of first rollers 26 rises, it can support a pipe diameter with a smaller diameter. When the double-shaft motor 29 operates, it drives the second sprocket 30 to rotate. Under the action of the second chain 301, the second sprocket 30 drives the first sprocket 27 at the lower end to rotate. Under the action of the first chain 28, it drives the first sprocket 27 at the upper end to rotate, so that the first roller 26 rotates. The rotation speed of the first roller 26 is synchronized with the rotation of the rubber hose, solving the problem of rubber rolling by the bracket during molding; the second elevator 32 can drive the third double-sided rack 33 to move up and down. When the third double-sided rack 33 moves up and down, it can drive the third gear 34 to rotate. When the third double-sided rack 33 rises, the second roller 36 rises; when the third double-sided rack 33 descends, the second roller 36 descends. When a pair of second rollers 36 descends, it can support a pipe diameter with a larger diameter. On the contrary, when a pair of second rollers 36 rises, it can support a pipe diameter with a smaller diameter.

[0060] The first driving device 1 and the second driving device 9 are used to clamp the pipe core and drive the pipe core to rotate, and the pipe core is used for the rubber hose molding;

[0061] The first driving device 1 includes a frame 101. A guide rail 102 is arranged on the upper surface of the frame 101. A moving seat 103 is slidably arranged left and right on the guide rail 102. The moving seat 103 is connected to the frame 101 through an oil cylinder 104. A hydraulic chuck 105 is installed on the moving seat 103. A first driving motor 106 is installed at the upper end of the moving seat 103. The first driving motor 106 is connected to the hydraulic chuck 105 through a belt pulley 107. The hydraulic chuck 105 is clamped with the tube core. Between the upper surface of the frame 101 and the moving seat 103 is 108. A manual operation panel 109 is arranged on the upper wall surface of the frame 101. A positioning fixture 110 is arranged on the first driving device 1 of the main machine near the support frame 10. The positioning fixture 110 includes a positioning frame 1101 installed on the frame 101 near the support frame 10. A hydraulic cylinder 1102 is installed at the lower end of the positioning frame 1101. A first double-sided rack 1103 is installed at the driving end of the hydraulic cylinder 1102. The front and rear sides of the first double-sided rack 1103 are meshed and connected with a first gear 1104. The first gear 1104 is rotatably installed on a mounting seat 1105. The mounting seat 1105 is installed on the positioning frame 1101. A positioning arm 1106 is installed at the upper end of the first gear 1104. A positioning wheel 1107 is rotatably installed on the inner wall surface of the positioning arm 1106. The structure of the second driving device 9 is the same as that of the first driving device 1 and is symmetrically arranged left and right with respect to the support frame 10.

[0062] Such as Figure 3As shown in the figure, when loading the die, the die is lifted by the bracket so that the axis of the die is aligned with the center of the positioning fixture 110. The die is clamped by the positioning fixture 110 to support the end of the die, preventing the end of the die from drooping downward when the end of the die is clamped by the hydraulic chuck 105, which facilitates the hydraulic chuck 105 to fix both ends of the die. The moving seat 103 can slide left and right on the guide rail 102, and the power is provided by the oil cylinder 104 to drive the movement of the moving seat 103. In addition, the oil cylinder 104 of the present invention can also be replaced by other existing driving devices such as electric push rods, lead screws, and air cylinders. Any driving device that can achieve the movement of the moving seat of the present invention in the horizontal direction can be used in the present invention. The equivalent replacement methods of other existing driving devices are not described in detail here. When fixing the die, the moving seat 103 is driven to approach the die so that the die is located within the hydraulic chuck 105. The die is fixed by the hydraulic chuck 105, and the die is fixed by increasing the pressure within the hydraulic chuck 105. When the hydraulic chuck 105 is depressurized, the die can be released. By rotating the first driving motor 106, the hydraulic chuck 105 rotates accordingly under the action of the belt pulley 107, realizing the rotation of the die fixed by the hydraulic chuck 105. In addition, the cooperation of the first driving motor 106 and the belt pulley 107 to provide power for the rotation of the hydraulic chuck 105 can also be replaced by other existing devices such as a motor and a belt. Any driving device that can achieve the self-rotation of the hydraulic chuck 105 in the present invention can be used in the present invention. The equivalent replacement methods of other existing driving devices are not described in detail here. The wires of the first driving motor 106 and the hydraulic pipes of the hydraulic chuck 105 and other pipelines are placed in the drag chain 108. The first driving motor 106 is a variable-frequency motor and can be steplessly speed-regulated to meet the requirements of different specifications of hose forming processes.

[0063] As Figure 4 shown, the up-and-down movement of the piston end of the hydraulic cylinder 1102 can drive the up-and-down movement of the first double-sided rack 1103, thereby causing the first gear 1104 to rotate. When the first double-sided rack 1103 rises, the upper ends of a pair of positioning arms 1106 move away from each other. When the first double-sided rack 1103 descends, the upper ends of the pair of positioning arms 1106 move closer to each other. When the positioning arms 1106 move closer to each other, the die is clamped by the positioning wheels 1107 to fix the position of the die.

[0069] As Figure 16 shown, the thick steel wire is inserted through the upper steel wire inlet, and the steel wire passes through the fourth guide wheels 72 in sequence, causing the steel wire to form a certain degree of bending. One end of the steel wire is wound around the tube core to facilitate winding the steel wire onto the tube core. The tension of the steel wire can be adjusted by pressing down the steel wire with the upper steel wire tension control device 73. The thin steel wire passes through the fifth guide wheels 75 in sequence, and the steel wire is deformed by the fifth guide wheels 75 to facilitate winding.

[0070] The upper rope mechanism 7 includes an upper rope box 81. A partition 82 is arranged inside the upper rope box 81. Three V-grooved wheels 83 are rotatably arranged on the left side of the partition 82. A fourth gear 84 is arranged at the right end of the V-grooved wheel 83. The fourth gears 84 are meshed and connected in sequence, and the number of teeth decreases in sequence in the rope outlet direction. The fourth gears 84 are located at the right end of the partition 82. A pneumatic brake 85 is arranged at the right end of the partition 82. A fifth gear 86 is sleeved on the pneumatic brake 85, and the fifth gear 86 is meshed with the last fourth gear 84. The front end of the upper rope box 81 is the inlet.

The diameters of the V-grooved pulleys 83 are 268 mm, 272 mm, and 276 mm successively from front to back, and the rotational speeds increase successively. The wire rope is clamped in the V-groove. As the linear velocity increases, the wire rope is gradually stretched. The more it is stretched, the closer it gets to the root of the groove. The closer it gets, the tighter the wire rope is clamped, and the greater the frictional force between the wire rope and the V-groove. The change in linear velocity between the grooved pulleys is achieved through gear meshing and wheel diameter change.

The first driving device 1 and the second driving device 9 move towards the tube core respectively. After arriving, the jaws of the hydraulic chuck 105 clamp the end of the core shaft. The second driving device 9 pulls the tube core backward to the set tension. The positioning fixture 110 opens, and the clamping is completed.

[0075] Step 2: Apply the release agent:

[0076] At the beginning of making the tube, support the tube core through the unpowered bracket 3. The first driving device 1 and the second driving device 9 rotate the tube core and apply the release agent to the tube core.

[0077] Raise the first roller 26 in the powered carriage 2 upward. The first roller 26 on the powered carriage 2 rises to support the core, causing the second roller 36 on the unpowered carriage 3 to move downward, so that the second roller 36 disengages from the core. Adjust the height of the first roller 26 to align the axis of the core with the center of the positioning fixture 110. After the positioning fixture 110 automatically clamps the core, the first drive device 1 and the second drive device 9 move towards the core. After reaching the position, the hydraulic chuck 105 clamps the core shaft head. The second drive device 9 pulls the core to move, pulling the core to reach the set tensile force. The positioning fixture 110 opens, and the loading is completed.

[0078] Step 3: Set parameters:

[0079] Set the parameters of each process according to the requirements of the process card.

[0080] Step 4: Wind the material:

[0082] Step 5: Wind the packaging film;

[0083] Step 6: Unbind the core;

[0084] Turn the bind / unbind knob on the operation panel to the unbind position. The stretching oil cylinder of the second drive device 9 is depressurized. The second drive device 9 moves forward until it stops. The positioning fixture 110 clamps the core. The jaws of the hydraulic chuck 105 open. The first drive device 1 and the second drive device 9 move in the opposite direction of the core to the final position and stop respectively.

[0087] The present invention is dedicated to processing large-diameter and long rubber hoses. Through the modular-designed support frame 10, the number of modules can be appropriately increased or decreased according to the length of the rubber hose to be produced. Stretch the pipe core through the driving devices on both sides of the support frame 10 to solve the problem of large jumping amplitude of the long pipe core during rotation. At the same time, there are a powered bracket 2 and an unpowered bracket 3 arranged on the support frame 10. Among them, the powered bracket 2 can adjust the height as the pipe-making materials are wound onto the pipe core to ensure that the axis of the pipe core is consistent with the axis of the hydraulic chuck 105.

Compared with single-layer feeding one by one, it saves time and has high pipe manufacturing efficiency. As the pipe manufacturing materials are wound onto the pipe core, the height of the powered bracket 2 will automatically adjust with the change of the pipe diameter to ensure that the axis of the pipe core is consistent with the center of the hydraulic chuck 105. Subsequently, wind the armored steel wire around the entire rubber hose. The armored steel wire plays a skeleton role and provides support and fixation for the rubber hose. Wind the fine steel wire around both ends of the rubber hose end to fix the rubber hose and the flange. Finally, wind the rope on the rubber hose to shape the rubber hose.

Adjust the walking speed of the vehicle body 41 by adjusting the rotation speed of the second driving motor 43, and adjust the walking speed of the vehicle body 41 by the winding pitch of the wound hose-making material. In the same way as above, according to the hose-making process, after the winding of the hose-making material is completed, wind the steel wire and the rope in sequence.

[0096] At present, the inner diameter of the rubber hose processed by the present invention can reach 150 - 254 mm, and the length can reach 50 m. For the equipment on the market, the inner diameter of the processed rubber hose is larger than that of the rubber hose produced by the present invention, but the length cannot reach 34 m. For those with a length greater than 34 m, the inner diameter cannot reach that of the rubber hose processed by the present invention. Moreover, the present invention can realize winding multiple hose-making materials onto the core at the same time, improving the processing efficiency compared with the traditional single feeding.

[0097] The present invention selects the support frame 10 with a modular design structure, which can support the long rubber hose. The two ends of the core are synchronously driven to rotate by the first driving motor 106 to avoid the problem of the rubber hose being distorted when rotating.
