DETAILED DESCRIPTION
[0023] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0024] See also Figure 1-6 The utility model provides a double-bend high-speed pipe bending machine suitable for pipes, including a fuel tank base 1, a left fuel tank 3, a right fuel tank 2 and a material return mechanism 9 are respectively arranged on the upper side of the fuel tank base 1, and the material return mechanism 9 is arranged in the middle of the left fuel tank 3 and the right fuel tank 2. The left fuel tank 3 and the right fuel tank 2 are both slidably connected to the fuel tank base 1, and the inner side surfaces of the left fuel tank 3 and the right fuel tank 2 are connected to a connecting shaft 5, and the connecting shaft 5 is respectively connected to an auxiliary thrust seat 8 and a wheel mold 4, and the inner side of the auxiliary thrust seat 8 is provided with a wheel mold 4, and the auxiliary thrust seat 8 is fixedly connected to the connecting shaft 5, and the wheel mold 4 is rotatably connected to the connecting shaft 5, an auxiliary pushing die 7 is arranged on the inner side of the auxiliary pushing seat 8, and the auxiliary pushing die 7 is arranged above the wheel die 4, the right side of the left oil tank 3 and the left side of the right oil tank 2 are fixedly connected with a support seat 10, an upper clamping die 6 is arranged on the inner side of the support seat 10, and the upper clamping die 6 is located above the wheel die 4, the inner sides of the support seat 10 and the auxiliary pushing seat 8 are fixedly connected with a pushing die cylinder 13, and the pushing die cylinder 13 is fixedly connected to the auxiliary pushing die 7 and the upper clamping die 6 respectively, and the left oil tank 3 and the right oil tank 2 are connected with a driving mechanism 14 for driving the connecting shaft 5.
[0025] The driving mechanism 14 is provided with two groups, each including a pushing cylinder, an internal gear and a rack. The pushing cylinder is fixed on the left oil tank 3 and the right oil tank 2 respectively. The left oil tank 3 and the right oil tank 2 are both provided with internal gear teeth and racks inside. The rack is meshed with the internal gear through the gear teeth. The internal gear is sleeved and fixed on the connecting shaft 5. The telescopic rod on the pushing cylinder is fixedly connected to the rack.
[0026] During the use of the utility model, the wheel die 4 is a profiling mold cavity installed on the connecting shaft 5. Different from the conventional pipe bending equipment design, the wheel die 4 and the lower die of the clamping die are designed as a whole, and the mold cavity is designed as a double-track profiling. The shape of the wheel die 4 track can be designed in reverse according to the shape presented at the bend after the pipe is bent. In this way, after the pipe is bent, the bend can be wrinkled and the arc is full. Due to the double track, the processing of bends with different requirements can be allowed. The upper clamping die 6 is a clamping device formed under the clamping die integrated with the wheel die 4. When the pipe is ready to bend, the upper and lower parts are closed to press the pipe so that it does not move. The auxiliary push die 7 and the auxiliary push seat 8 are a combined device, and rely on the push die oil cylinder 13 on the clamping die at the same time. When the push die cylinder 13 is working, the auxiliary push die 7, the auxiliary push seat 8, and the upper clamping die 6 move downward together to press the pipe fittings. After keeping them fixed, the push oil tanks on the left oil tank 3 and the right oil tank 2 are operated to drive the rack to move up and down, thereby driving the internal gear to rotate, and then driving the connecting shaft 5, the auxiliary push seat 8 and the auxiliary push die 7 to rotate. The internal gear and the rack drive the auxiliary push seat 8 to rotate, pushing the auxiliary push die 7 to bend the pipe according to the angle required by the drawing. The tank base 1 is the power control center of the entire pipe bending machine. The pump in the tank is designed to be high-power and cooperate with the oil cylinder installed outside, and the program in the controller is optimized to achieve a qualitative improvement in the bending time. After adjustment, the bending time can be increased from the conventional 10-12s to 5-6s, greatly improving efficiency and saving time.
[0027] Before processing, adjust the horizontal screws at the lower side of the left oil tank 3 and the right oil tank 2 according to the requirements of the drawings, adjust the bolts at the inner connection of the left and right oil tanks 2 to adjust the roll angles of the oil tanks on both sides to match the drawings, and there are two contoured pipe fitting cavities 41 on the wheel mold 4. The wheel mold 4 cavity of the accessory to be processed can be selected according to the requirements of the drawings. After the preparation work is completed, start the start button, and the controller controls the equipment to start moving. At this time, the push mold cylinder 13 pushes the auxiliary push mold 7 and the clamping mold to move downward to press the pipe fitting. After keeping it fixed, the auxiliary push seat 8 is driven by the gears and racks in the oil tanks on both sides to rotate, and the auxiliary push mold 7 is pushed to bend the pipe according to the angle required by the drawings. Processing at multiple angles can be achieved at the same time. After the pipe bending is completed, the material return mechanism 9 starts to work, and the material return cylinder 93 pushes the ejection plate 92. The ejection plate 92 acts on the pipe fitting to eject it, completing the pipe bending.
[0028] like Figure 1As shown, a guide rail 11 is fixedly connected to the upper side of the fuel tank base 1, and two sliding seats 12 are slidably connected to the guide rail 11. The left fuel tank 3 and the right fuel tank 2 are respectively fixed on the two sliding seats 12, so that the left fuel tank 3 and the right fuel tank 2 can move left and right along the fuel tank base 1.
[0029] like Figure 1 As shown, the left fuel tank 3 and the right fuel tank 2 are a symmetrical component, and four bolt adjustment holes and horizontal screws are provided at the bottom of the left fuel tank 3 and the right fuel tank 2. The spacing between the two elbows can be adjusted by adjusting the horizontal screws forward and backward, and the in and out of the bolts on the four bolt positions can be adjusted to adjust the tilting angle of the fuel tanks on both sides, so as to bend out the third coordinate size required by the drawing.
[0030] like Figure 2-4 As shown, two groups of pipe cavities 41 are provided on the upper side of the wheel die 4, which allow the processing of elbows with different required sizes.
[0031] like Figure 1 As shown, the cross section of the support seat 10 is L-shaped, and the front end plate of the wheel mold 4 is arranged on the bottom of the support seat 10, so as to facilitate the limited support of the wheel mold 4.
[0032] like Figure 5 As shown, the material return mechanism 9 includes a fixed seat 91, a material return plate 92 and a material return cylinder 93. The fixed seat 91 is fixed on the oil tank base 1, and four groups of material return cylinders 93 are fixedly connected to the upper side of the fixed seat 91. The upper side of the material return cylinder 93 is connected to the material return plate 92. The upper side surface of the material return plate 92 is an inclined surface. The design of the inclined surface facilitates sliding return of the pipe fittings after bending. The material return cylinder 93 runs and drives the material return plate 92 to move upward, thereby driving the pipe fittings to move upward and separate from the wheel mold 4, thereby achieving the purpose of automatic material return.
[0033] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
