Description

Technical Field

[0001] This utility model relates to pipe processing equipment, and more particularly to an integrated machine for bending, flattening and punching pipes. Background Technology

[0002] Pipe bending machines are mechanical devices used to process various pipes and pipe fittings, and are widely used in construction, power, petrochemical, aerospace and other fields. With the continuous advancement of domestic infrastructure construction, the acceleration of industrial upgrading and the continuous upgrading of technology, the processing efficiency and precision of pipe bending machines have been continuously improved, making them an indispensable piece of equipment in modern industrial production.

[0003] Currently available pipe bending machines can only bend pipes. If flattening, punching, and bending of pipes are required, additional flattening equipment and punching equipment are needed on top of the existing pipe bending machine. This results in several drawbacks: firstly, it requires space for three machines, leading to a large overall footprint; secondly, it increases equipment operating costs; and thirdly, it necessitates multiple clamping and positioning of the pipes, which is time-consuming and labor-intensive, and these repeated clamping and positioning can affect positioning accuracy, thus impacting the final pipe processing quality and failing to improve the pipe pass rate. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an integrated pipe bending, flattening and punching machine that integrates pipe bending, flattening and punching. The equipment has a simple and compact structure, occupies little space, has low operating costs, and only requires clamping the pipe once when performing the three processes of flattening, punching and bending, which saves time and effort and has high positioning accuracy.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: The integrated pipe bending, flattening, and punching machine has a base installed on the front side of the pipe output end of the original pipe bending machine. A movable frame is installed on the base via a front-to-back sliding structure, and the movable frame can move back and forth relative to the base via the front-to-back sliding structure, thereby moving away from or closer to the pipe output end of the pipe bending machine. A die holder is provided on the movable frame, and the die holder is installed on the movable frame via a left-to-right sliding structure, and the die holder can move left and right relative to the movable frame via the left-to-right sliding structure. A flattening assembly for flattening the pipe and a punching assembly for punching the pipe are provided on the die holder. The flattening assembly and the punching assembly can be commercially available flattening assemblies and punching assemblies.

[0006] To improve the overall structural compactness, this solution integrates the flattening assembly and the punching assembly onto the same main support base. The main support base is concave in shape, consisting of an upper support base, a lower support base, and a vertical support base. The top of the vertical support base is connected to the right end of the upper support base, and the bottom of the vertical support base is connected to the right end of the lower support base. The lower support base is fixedly mounted on the die base. The flattening assembly is located in the left half of the main support base, and the punching assembly is located in the right half of the main support base.

[0007] Furthermore, in the aforementioned pipe bending, flattening, and punching integrated machine, a blanking box is provided on the front side wall of the mold base. The finished pipes after bending, flattening, and punching are blanked into the blanking box, and the blanking blanks during the punching process are also blanked into the blanking box.

[0008] Furthermore, in the aforementioned integrated bending, flattening, and punching machine, the flattening assembly has the following structure: a flattening lower die is provided on the top surface of the lower support base; a through-hole is provided on the upper support base, extending vertically to the left; the through-hole is located above the flattening lower die; a flattening upper die receiving cavity is provided at the bottom end of the through-hole; a left movable rod is movably inserted into the through-hole, and its bottom extends beyond the bottom end of the through-hole and is fixedly connected to the flattening upper die; a first support plate is fixedly provided on the left movable rod extending beyond the top end of the through-hole; at least two first movable holes are provided on the first support plate, and a first support rod is movably inserted into each first movable hole; each first support rod... The axis of the first support rod is parallel to the axis of the left movable rod. Each first support rod has a protruding first top protrusion at its top. The bottom of each first support rod is fixedly connected to the upper support base. Each first support rod is fitted with a first spring. Under the elastic force of each first spring, the upper end of each first spring presses against the bottom surface of the first support plate, and the lower end of each first spring presses against the top surface of the upper support base. The first top protrusions on each first support rod press against the top surface of the first support plate, flattening the upper section of the upper mold into the flattening upper mold receiving cavity. A left drive assembly is provided on the mold base. The left drive assembly can drive the left movable rod to move downward against the elastic force of each first spring.

[0009] In this design, the number of first movable holes on the first support plate is preferably four. The four first movable holes are evenly spaced around the center line of the left movable rod and are arranged in a circular pattern on the first support plate. This arrangement allows the left movable rod to move up and down more smoothly without any deviation.

[0010] Furthermore, in the aforementioned integrated pipe bending, flattening, and punching machine, the structure of the punching assembly is as follows: a lower punching die is provided on the top surface of the lower support base; a through-hole is provided on the upper support base, extending vertically through the lower part, located above the lower punching die; a receiving cavity for the upper punching die is provided at the bottom end of the right through-hole; a right movable rod is movably inserted into the right through-hole, and its bottom extends beyond the bottom end of the right through-hole and is fixedly connected to the upper punching die; a second support plate is fixedly provided on the right movable rod extending beyond the top end of the right through-hole; at least two second movable holes are provided on the second support plate; and in each second movable hole... A second support rod is movably inserted into each hole. The axis of each second support rod is parallel to the axis of the right movable rod. A protruding second top protrusion is provided at the top of each second support rod. The bottom of each second support rod is fixedly connected to the upper support base. A second spring is fitted on each second support rod. Under the elastic force of each second spring, the upper end of each second spring abuts against the bottom surface of the second support plate, and the lower end of each second spring abuts against the top surface of the upper support base. The second top protrusions on each second support rod abut against the top surface of the second support plate. The upper section of the punching die enters the punching die receiving cavity.

[0011] A lower connecting plate, a cylindrical buffer pad, and an upper connecting plate are fixedly installed sequentially from bottom to top on the top of the right movable rod. A connecting hole communicating with the inner hole of the cylindrical buffer pad is opened on the lower connecting plate, and a through hole penetrating vertically is opened on the right movable rod. The through hole and the connecting hole are positioned vertically. The top of the connecting rod, which is inserted into the inner hole of the cylindrical buffer pad, is fixedly connected to the upper connecting plate. The lower part of the connecting rod passes through the connecting hole and extends into the through hole to connect with the punching tool. The elastic force of the buffer pad is greater than the total spring force applied to the second support plate by each of the second springs. A right drive assembly is provided on the mold base, which can drive the right movable rod to move downward against the elastic force of each of the second springs.

[0012] In this design, the number of second movable holes on the second support plate is preferably four. The four second movable holes are evenly spaced around the center line of the right movable rod on the second support plate. This arrangement allows the right movable rod to move up and down more smoothly without any deviation.

[0013] To improve the overall structural compactness and reduce manufacturing costs, this solution sets the left drive assembly and the right drive assembly as a single main drive assembly. The structure of this main drive assembly is as follows: a drive support frame is provided on the mold base, the cylinder body of the flattening and punching cylinder is mounted on the drive support frame, and the piston rod of the flattening and punching cylinder points downward.

[0014] When the die holder moves to the position of the flattening assembly below the piston rod of the flattening and punching cylinder via the left and right sliding structure, the flattening and punching cylinder is activated. The piston rod of the flattening and punching cylinder extends downward to contact the left movable rod and continues to extend downward, driving the left movable rod to overcome the elastic force of each first spring and move downward to flatten the tube located in the flattening assembly.

[0015] When the die holder moves to the position below the piston rod of the flattening die cylinder via the left and right sliding structure, the flattening die cylinder is activated. The piston rod of the flattening die cylinder extends downward to contact the upper connecting plate and continues to extend downward, driving the right movable rod to move downward against the elastic force of each second spring. After the upper die and lower die clamp the tube in the die assembly, the piston rod of the flattening die cylinder continues to extend downward, compressing the cylindrical buffer pad. The cylindrical buffer pad deforms into a drum shape, driving the connecting rod to drive the die cutting tool to perform the die cutting operation on the tube in the die assembly.

[0016] Furthermore, in the aforementioned pipe bending, flattening, and punching integrated machine, the front-to-back sliding structure is as follows: the movable frame is mounted on the base via a linear guide rail, the cylinder body of the pipe inlet cylinder is connected to the base, and the piston rod end of the pipe inlet cylinder is fixedly connected to the movable frame; when the piston rod of the pipe inlet cylinder extends outward or retracts inward, it drives the movable frame to move back and forth along the linear guide rail.

[0017] Furthermore, in the aforementioned pipe bending, flattening, and punching integrated machine, the left and right sliding structure is as follows: the mold base is movably mounted on the moving frame via a slide rail groove structure, the cylinder body of the mold changing cylinder is fixedly installed on the moving frame, and the piston rod end of the mold changing cylinder is fixedly connected to the mold base; when the piston rod of the mold changing cylinder extends outward or retracts inward, it drives the mold base to move left and right along the slide rail, thereby adjusting the left and right positions of the flattening assembly and the punching assembly. When it is necessary to flatten the pipe, the flattening assembly is moved to the front of the pipe output end of the pipe bending machine; when it is necessary to punch the pipe, the punching assembly is moved to the front of the pipe output end of the pipe bending machine.

[0018] The beneficial effects of this utility model are: the above-mentioned pipe bending, flattening and punching integrated machine integrates pipe bending, flattening and punching. Compared with the traditional separate pipe bending machine, punching equipment and flattening equipment, it greatly reduces the space occupied and the cost is also reduced. It saves time and effort and greatly improves the processing efficiency. In addition, the three processes of pipe bending, flattening and punching can be completed in one clamping, which greatly improves the processing accuracy and the product qualification rate.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example 1

[0029] The pipe bending, flattening, and punching integrated machine described in this embodiment is an improved design based on the existing pipe bending machine 1, such as... Figure 1 As shown, a base 2 is provided on the front side of the pipe output end of the existing pipe bending machine 1. A movable frame 3 is installed on the base 2 through a front-to-back sliding structure, and the movable frame 3 can move back and forth relative to the base 2 through the front-to-back sliding structure, thereby moving away from or closer to the pipe output end of the pipe bending machine 1. Figure 1 and Figure 2 As shown, the forward and backward sliding structure in this embodiment is as follows: the movable frame 3 is mounted on the base 2 via a linear guide rail; the cylinder body 31 of the inlet cylinder is connected to the base 2; and the end of the piston rod 32 of the inlet cylinder is fixedly connected to the movable frame 3. When the piston rod 32 of the inlet cylinder extends outward, it pushes the movable frame 3 forward along the linear guide rail; conversely, when the piston rod 32 of the inlet cylinder retracts inward, it pulls the movable frame 3 backward along the linear guide rail.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a mold base 4 is provided on the movable frame 3. The mold base 4 is installed on the movable frame 3 via a left-right sliding structure, and the mold base 4 can move left and right relative to the movable frame 3 via the left-right sliding structure. The left-right sliding structure in this embodiment is as follows: the mold base 4 is movably set on the movable frame 3 via a slide rail and groove structure, the cylinder body 41 of the mold changing cylinder is fixedly installed on the movable frame 3, and the end of the piston rod 42 of the mold changing cylinder is fixedly connected to the mold base 4. When the piston rod 42 of the mold changing cylinder extends outward, it pushes the mold base 4 to move to the left along the slide rail; conversely, when the piston rod 42 of the mold changing cylinder retracts inward, it pulls the mold base 4 to move to the right along the slide rail.

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, the die base 4 is provided with a flattening assembly 7 for flattening the pipe and a punching assembly 8 for punching the pipe. The flattening assembly 7 and the punching assembly 8 can be commercially available flattening assemblies and punching assemblies.

[0032] The pipe bending machine 1 typically consists of several main structural parts: a pipe bending mechanism assembly 11, a feeding trolley assembly 12, and a core-pulling assembly 13. The pipe, with the cooperation of the feeding trolley assembly 12 and the core-pulling assembly 13, enters the pipe bending mechanism assembly 11 and then extends forward beyond it. At this point, the front end of the pipe is located at the pipe output end of the pipe bending machine 1. The infeed cylinder is activated, and its piston rod 32 retracts inward, pulling the moving frame 3 backward along the linear guide rail to the designated position. Then, the die-changing cylinder is activated, and its piston rod 42 extends outward, pushing the die holder 4 to the left until the flattening assembly 7 moves to the front of the pipe output end of the pipe bending machine 1. Driven by the feeding trolley assembly 12, the pipe extends into the flattening assembly 7, where the end of the pipe is flattened. After the flattening operation is completed, the die-changing cylinder is activated. The piston rod 42 of the die-changing cylinder extends outward, pushing the die holder 4 to continue moving to the left until the punching assembly 8 moves to the front of the pipe output end of the pipe bending machine 1. At this time, the pipe end is transferred from the flattening assembly to the punching assembly 8, where the punching assembly 8 performs the punching operation on the pipe end. After the punching operation is completed, the pipe bending machine starts the pipe bending operation.

[0033] The aforementioned pipe bending, flattening, and punching integrated machine combines pipe bending, flattening, and punching into one unit. Compared with the traditional separate pipe bending machine, punching equipment, and flattening equipment, it greatly reduces the space occupied and the cost, saves time and labor, and greatly improves processing efficiency. In addition, using this equipment, the three processes of pipe bending, flattening, and punching can be completed in one clamping, which greatly improves the processing accuracy and the product qualification rate. Example 2

[0034] This embodiment is based on Embodiment 1, with a more compact design of the positions of the flattening assembly 7 and the punching assembly 8, so that the flattening assembly 7 and the punching assembly 8 share the same main support base 5, such as... Figure 4 As shown, the main support base 5 is concave in shape, consisting of an upper support base 51, a lower support base 53, and a vertical support base 52. The top of the vertical support base 52 is connected to the right end of the upper support base 51, and the bottom of the vertical support base 52 is connected to the right end of the lower support base 53. The lower support base 53 is fixedly installed on the mold base 4. The flattening assembly 7 is located in the left half of the main support base 5, and the punching assembly 8 is located in the right half of the main support base 5.

[0035] The preferred solution is to further provide a material drop box 41 on the front side wall of the mold base 4, based on the above structure. Figure 2 As shown, the finished pipes after bending, flattening and punching are placed in the blanking box 41, and the blanking blanks during the punching process are also placed in the blanking box 41.

[0036] like Figure 4 , Figure 5 and Figure 6 As shown, the structure of the flattening assembly 7 in this embodiment is as follows: a flattening lower mold 77 is provided on the top surface of the lower support 53, and a left through hole 511 is provided on the upper support 51, which is located above the flattening lower mold 77. A flattening upper mold receiving cavity 512 is provided inward at the bottom end of the left through hole 511. The left movable rod 71 is movably inserted into the left through hole 511. The bottom of the left movable rod 71 extends out of the bottom end of the left through hole 511 and is fixedly connected to the flattening upper mold 72. A first support plate 75 is fixedly installed on the left movable rod 71 extending out of the top end of the left through hole 511. At least two first movable holes are opened on the first support plate 75. A first support rod 73 is movably inserted into each first movable hole. The axis of each first support rod 73 is parallel to the axis of the left movable rod 71. A first top protrusion 76 is provided at the top of each first support rod 73. The bottom of each first support rod 73 is fixedly connected to the upper mold 72. On the upper support base 51, a first spring 74 is fitted on each first support rod 73. Under the elastic force of each first spring 74, the upper end of each first spring 74 presses against the bottom surface of the first support plate 75, and the lower end of each first spring 74 presses against the top surface of the upper support base 51. The first top protrusion 76 on each first support rod 73 presses against the top surface of the first support plate 75. The upper section of the flattened upper mold 72 enters the flattened upper mold receiving cavity 512. A left drive assembly is provided on the mold base 4. The left drive assembly can drive the left movable rod 73 to move downward against the elastic force of each first spring 74.

[0037] In this embodiment, a more preferred option is that the number of first movable holes on the first support plate 75 is preferably four. The four first movable holes are evenly spaced around the center line of the left movable rod 71 on the first support plate 75. This arrangement allows the left movable rod 71 to move up and down more smoothly without any deviation.

[0038] like Figure 4 , Figure 5 and Figure 6As shown, the structure of the punching assembly 8 in this embodiment is as follows: a lower punching die 87 is provided on the top surface of the lower support 53; a through hole is provided on the upper support 51, extending vertically to the right; the through hole is located above the lower punching die 87; a receiving cavity for the upper punching die is provided at the bottom end of the through hole; a right movable rod is movably inserted into the through hole; the bottom of the right movable rod extends out of the bottom end of the through hole and is fixedly connected to the upper punching die 82; a second support plate 85 is fixedly provided on the right movable rod extending out of the top end of the through hole; at least two second movable holes are provided on the second support plate 85; and a second support rod 83 is movably inserted into each second movable hole. The axis of each second support rod 83 is parallel to the axis of the second movable rod. A second top protrusion 86 is provided on the top of each second support rod 83. The bottom of each second support rod 83 is fixedly connected to the upper support seat 51. A second spring 84 is fitted on each second support rod 83. Under the elastic force of each second spring 84, the upper end of each second spring 84 presses against the bottom surface of the second support plate 85, and the lower end of each second spring 84 presses against the top surface of the upper support seat 51. The second top protrusion 86 on each second support rod 83 presses against the top surface of the second support plate 85. The upper section of the upper punching die 82 enters the upper punching die receiving cavity.

[0039] In this embodiment, a more preferred option is that the number of second movable holes opened on the second support plate 85 is preferably four. The four second movable holes are evenly spaced around the center line of the right movable rod and are distributed on the second support plate 85. This arrangement allows the right movable rod to move up and down more smoothly without any deviation.

[0040] A lower connecting plate 91, a cylindrical buffer pad 92, and an upper connecting plate 93 are fixedly installed sequentially from bottom to top on the top of the right movable rod. A connecting hole communicating with the inner hole of the cylindrical buffer pad 92 is opened on the lower connecting plate 91. A through hole penetrating vertically is opened on the right movable rod, located below the connecting hole. The top of the connecting rod 9, which passes through the inner hole of the cylindrical buffer pad 92, is fixedly connected to the upper connecting plate 93. The lower part of the connecting rod 9 passes through the connecting hole and extends into the through hole to connect with the punching tool. The elastic force of the buffer pad 92 is greater than the total spring force exerted by each of the second springs 84 on the second support plate 85. A right drive assembly is provided on the mold base 4, which can drive the right movable rod to move downwards against the elastic force of each of the second springs 84.

[0041] In this embodiment, the left drive assembly and the right drive assembly are the same total drive assembly 6, and the structure of the total drive assembly 6 is as follows: Figure 3As shown, a drive support frame 63 is provided on the mold base 4, the cylinder body 61 of the flattening and punching oil cylinder is installed on the drive support frame 63, and the piston rod 62 of the flattening and punching oil cylinder points downward.

[0042] When the die holder 4 moves to a position below the piston rod 62 of the flattening and punching cylinder via the left-right sliding structure, the flattening and punching cylinder is activated. The piston rod 62 of the flattening and punching cylinder extends downwards until it contacts the left movable rod 61, and then continues to extend downwards, driving the left movable rod 61 to overcome the elastic force of each first spring 64 and move downwards, thus flattening the tube located in the flattening assembly 7. See [link to relevant documentation]. Figure 4 The diagram shown illustrates the state of the flattening assembly 7 when no flattening operation has been performed. (See attached diagram) Figure 5 The diagram shows the state of the flattening assembly 7 during the flattening operation.

[0043] When the die holder 4 moves to the position below the piston rod 62 of the flattening die cylinder via the left and right sliding structure, the flattening die cylinder is activated. The piston rod 62 of the flattening die cylinder extends downward to contact the upper connecting plate 93 and continues to extend downward, driving the right movable rod to move downward against the elastic force of each second spring 84. After the upper die 82 and the lower die 87 clamp the tube located in the punching assembly 8, the piston rod 62 of the flattening die cylinder continues to extend downward, compressing the cylindrical buffer pad 92. The cylindrical buffer pad 92 deforms, resembling a drum shape. (See [reference]). Figure 6 As shown, the drive connecting rod 9 drives the punching cutter to perform punching operations on the tube located in the punching assembly 8.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
