Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pipe processing, and particularly relates to a pipe processing device. BACKGROUND

[0002] A common refrigeration and heating equipment, such as an air conditioner, generally has a heat dissipation mechanism, such as a heat radiator on the outdoor unit of the air conditioner, which is generally composed of a pipe. Specifically, the pipe is composed of a plurality of separate U-shaped pipes arranged side by side, and one or more U-shaped pipes form a pipe unit. Each pipe unit is connected with a connecting plate to be installed on the corresponding equipment. In actual application, a heat dissipation sheet is generally wrapped around the pipe to spread the heat from point to surface, thereby improving the heat dissipation effect. The heat dissipation sheet is generally manufactured in a flat sleeve structure, and the sleeve has a row of holes (similar to the sleeve holes in a business card holder). Each U-shaped pipe is sleeved in the hole of the row of holes to make the spacing between adjacent U-shaped pipes uniform, and the plurality of pipe units form an integral whole under the wrapping of the sleeve.

[0003] For the production process of the pipe, the U-shaped pipe is sleeved in the row of holes of the sleeve, and a connecting plate of a corresponding size is installed on the end of the U-shaped pipe. Then, according to the installation requirements of the equipment, the pipe wrapped by the sleeve is cut to divide the pipe into a plurality of pipe units, which are then installed on the corresponding equipment. Alternatively, the sleeve can not be completely cut, so that the adjacent pipe units remain connected, and the two connected pipe units are processed into a bent pipe by bending, thereby meeting the installation requirements of the equipment.

[0004] It can be seen that the current pipe processing operation is very complex. Not only is it necessary to accurately cut the pipe into pipe units of a corresponding size, but it is also necessary to accurately control the cutting depth according to the installation requirements, so that the adjacent pipe units remain connected after cutting to be processed into a bent pipe after bending. Therefore, in the prior art, manual positioning and cutting are generally used for processing, which results in low positioning accuracy, high processing cost, and difficulty in ensuring the uniformity of the processed pipe, and the quality of the finished product is poor. SUMMARY

[0005] The purpose of the embodiment of the application is to provide a pipe processing device, which is set according to the current processing requirements of the pipe to solve the technical problems of low positioning accuracy and low uniformity of the processed product in the prior art.

[0006] To achieve the above purpose, the technical solution adopted by the application is to provide a pipe processing device for cutting a pipe sleeved with a sleeve to divide the pipe into a plurality of pipe units, the pipe processing device comprising:

[0007] a workbench for placing the pipe;

[0008] An upper support is arranged above the workbench, and a guide rail is arranged on the upper support; the workbench is provided with a guide groove arranged in parallel with the guide rail;

[0009] A cutting mechanism is arranged on the upper support and connected with the guide rail; the cutting mechanism comprises a cutter for cutting the thin sleeve on the tube bundle; the cutting mechanism can be displaced above the workbench along the guide rail, so that the cutter passes through the guide groove of the workbench.

[0010] The tube bundle machining device has the following advantages: compared with the prior art, the tube bundle machining device is provided with a workbench on which the tube bundle can be horizontally placed; the cutting mechanism is arranged above the workbench through the upper support and can be displaced along the guide rail on the upper support, so that the cutter can be smoothly moved above the workbench to cut the thin sleeve on the tube bundle from above, so that the tube bundle can be divided into multiple tube bundle units. In this way, the tube bundle is efficiently cut by the automatic equipment to replace the traditional manual positioning and cutting operation, effectively reduces the processing cost, and can ensure the uniformity of the processing products, thereby improving the production efficiency. Since the cutter is moved from above the workbench to cut the tube bundle placed on the workbench, the cutting depth of the cutter can be adjusted by adjusting the height of the upper support to selectively completely cut the thin sleeve on the tube bundle to divide multiple tube bundle units, or incompletely cut to keep the adjacent tube bundle units connected for subsequent bending operation. This is conducive to adapting to different processing requirements and effectively improving the cutting precision of the cutter. In addition, since the cutter uses the guide groove on the workbench as the cutting line to divide the tube bundle, the cutting position of the tube bundle can be accurately positioned according to the guide groove as the reference line, thereby effectively improving the positioning accuracy.

[0011] The structure of the pipe machining device is improved, and the pipe machining device further comprises a lower support having a supporting plane for supporting the workbench, and the upper support is arranged on the supporting plane. For the case that small-size pipes cannot be cut through the bottom. On the one hand, the machining device adopts an upper cutting mode, that is, the cutter cuts the thin sleeve on the pipe from above. On the other hand, the lower support of the machining device has a supporting plane, which can not only be used for mounting and fixing the workbench and the upper support, but also form a supporting plane below the workbench. In this way, the width of the guide groove in the workbench is not limited, and multiple cutters can pass through. When machining small-size pipes, the pipe units in the middle of the pipe are cut and separated by the cutter, and the separated pipe units can be supported on the workbench or the supporting plane of the lower support, thereby avoiding damage caused by the direct falling of the separated pipe units to the ground, effectively ensuring the yield of the pipe units, and further improving the applicability of the machining device.

[0012] The structure of the cutting mechanism is improved, and the cutting mechanism further comprises a first driver and a tool holder for mounting the cutter. The first driver is connected with the tool holder and drives the tool holder to displace the cutter along the guide rail. The first driver and the tool holder can be connected through a driving shaft or a connecting belt, so that the tool holder can stably displace above the workbench, which is conducive to adjusting the cutting depth of the cutter by adjusting the height of the upper support or the tool holder, and effectively improving the cutting precision of the cutter.

[0013] Further, a plurality of mounting plates are arranged on the tool holder, the mounting plates extend downward, and the cutter is mounted on the extended end of the mounting plate. The number of the mounting plates is the same as that of the guide grooves on the workbench and the positions of the mounting plates correspond to those of the guide grooves. In this way, according to the machining requirements, a corresponding number of guide grooves can be selectively arranged on the workbench, and a corresponding number of cutters can be arranged for cutting operation. The machining device can complete the multiple cutting of the pipe in one cutting, so as to cut the pipe into multiple pipe units in batches, and effectively improve the production efficiency. In addition, the length of the downward extension of the mounting plate can be adjusted to adjust the cutting depth of the cutter and improve the cutting precision of the cutter.

[0014] The structure of the lower support is improved, and the supporting plane of the lower support further comprises a limiting mechanism for preventing the pipe from being displaced when being cut. The limiting mechanism comprises an abutting piece for abutting against the pipe, and the cutting mechanism displaces in the direction of the abutting piece during cutting. In this way, the abutting piece can abut against the pipe placed on the workbench in the moving direction of the cutter, effectively preventing the pipe from being displaced by the cutter during cutting, and further ensuring the cutting accuracy of the pipe.

[0015] Further, the limiting mechanism further comprises a fixing seat selectively connected with the abutting piece, the fixing seat and the abutting piece are both provided with mounting holes for fasteners to pass through, and the support plane of the lower support has a plurality of adjusting holes for adjusting the fixed positions of the fixing seat and / or the abutting piece. In order to improve the abutting strength, the fixing seat is selectively added on the support plane of the lower support and is connected with the abutting piece integrally to abut the pipe together, thereby effectively improving the support strength and the fixing effect on the pipe. The support plane of the lower support has a plurality of adjusting holes to cooperate with the mounting holes on the fixing seat and the abutting piece, and the fasteners pass through to adjust the fixed positions of the fixing seat and the abutting piece on the support plane, so as to adapt to the pipes of different sizes placed on the workbench and effectively improve the adaptability.

[0016] The structure of the pipe processing device is further improved, and the pipe processing device further comprises a bending mechanism for bending the pipe placed on the workbench, the bending mechanism comprises an upper pressing assembly and a lower pressing assembly, the upper pressing assembly is arranged on the upper support and can move downward to the pipe, and the lower pressing assembly is arranged on the lower support, the upper pressing assembly and the lower pressing assembly correspond in position and can clamp and bend the pipe from top to bottom. In this way, the processing device of the present application also integrates the bending mechanism for bending the pipe. The bending mechanism is composed of the upper pressing assembly and the lower pressing assembly, and the upper pressing assembly and the lower pressing assembly clamp and bend the pipe unit to be bent, so that the connected pipe units can form a bent pipe.

[0017] Further, the upper pressing assembly comprises a second driver, a pressing plate, a movable plate and a lifting mechanism, the pressing plate is connected with the lifting mechanism, the lifting mechanism can drive the pressing plate to move up and down, the movable plate is connected with the pressing plate through a rotating shaft, a linkage member is connected between the movable plate and the second driver, and the second driver can drive the movable plate to make a bending movement by abutting against the pipe from above. In this way, the lifting mechanism of the upper pressing assembly drives the pressing plate and the movable plate to move downward, so that the pressing plate is pressed on the pipe unit on the workbench, and the movable plate and the lower pressing assembly clamp the pipe unit outside the workbench; then, under the driving of the second driver, the movable plate and the lower pressing assembly bend the pipe unit together, so that the two connected pipe units form a bent pipe body.

[0018] Furthermore, the lower pressing assembly includes a third driver and a support plate. The supporting plane of the lower bracket is provided with a connecting seat and a through groove for the support plate to move. The support plate is located within the through groove and is connected to the connecting seat via a rotating shaft. The drive shaft of the third driver is connected to the support plate, driving the support plate to support the pipe arrangement from below in a bending motion. The support plate supports the pipe arrangement unit located outside the worktable after being cut and separated, and clamps the pipe arrangement unit with the movable plate in the upper pressing assembly. Driven by the third driver, the support plate and the movable plate of the upper pressing assembly move simultaneously to bend the pipe arrangement unit.

[0019] The bending function of the pipe-laying processing device is improved. The multiple sets of pipe-laying units are each connected to a connecting plate, and adjacent connecting plates have a connecting portion. The pipe-laying processing device also includes a stop mechanism that deforms the connecting portion between adjacent connecting plates. The stop mechanism includes a fourth driver and a movable component, with a pin on the movable component. The drive shaft of the fourth driver is connected to the movable component and drives the movable component to move onto the connecting plate, where the pin abuts against the connecting portion between adjacent connecting plates. This allows the connecting portion between adjacent connecting plates to deform when the upper and lower pressing components bend the pipe-laying unit, thereby reducing the force on the pipe-laying unit and enabling the connected pipe-laying units to be bent smoothly, effectively protecting the pipe-laying units and preventing damage during the bending process.

[0042] In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0043] Now the tube processing device provided by the embodiment of the present application will be described in detail. The tube processing device of the present application is mainly used for cutting the tube assembled by the thin sleeve to make the whole tube cut into multiple groups of corresponding specification tube units to meet the installation requirements of the equipment.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3 , the tube processing device includes a workbench 1 for placing the tube, an upper support 2 and a cutting mechanism 3.

[0045] The upper support 2 is supported above the workbench 1, and the upper support 2 is provided with a guide rail 21, and the workbench 1 is provided with a guide groove 11 arranged in parallel with the guide rail 21.

[0046] The cutting mechanism 3 is arranged on the upper support 2 and connected with the guide rail 21. The cutting mechanism 3 includes a cutter 31 for cutting the thin sleeve on the tube, and the cutting mechanism 3 can displace above the workbench 1 along the guide rail 21 to pass through the guide groove 11 of the workbench 1 to realize the cutting of the tube.

[0047] Compared with the prior art, the pipe processing device provided by the embodiment of the present application has a workbench 1 on which the pipe can be horizontally placed, and a cutting mechanism 3 is arranged above the workbench 1 through an upper support 2 and can displace along a guide rail 21 on the upper support 2, so that the cutter 31 can stably move above the workbench 1 to cut the thin sleeve on the pipe from above, so that the pipe can be divided into multiple pipe units. In this way, the pipe is efficiently cut by the automatic equipment to replace the traditional manual positioning and cutting operation, effectively reduces the processing cost, and can ensure the uniformity of the finished product, thereby improving the production efficiency.

[0048] In the embodiment of the present application, the cutter 31 is moved from above the workbench 1 to cut the pipe placed on the workbench 1, so that the cutting depth of the cutter 31 can be adjusted by adjusting the height of the upper support 2 to selectively completely cut the thin sleeve on the pipe to divide multiple pipe units or incompletely cut the thin sleeve to keep the adjacent pipe units connected for subsequent bending operation. This is beneficial to adapt to different processing requirements and effectively improves the cutting precision of the cutter 31.

[0049] In addition, the cutter 31 uses the guide groove 11 on the workbench 1 as the cutting line to divide the pipe, so that the division position of the pipe can be accurately positioned according to the guide groove 11 as the reference line, and the positioning precision is effectively improved.

[0050] In actual application, for a pipe with a large volume or a standard specification, the workbench 1 is generally provided with guide grooves 11 corresponding to the number of cutters 31, so that the cutter 31 can pass through the corresponding guide groove 11 to complete the cutting operation. The pipe unit cut and separated will be supported on the workbench 1. However, for a pipe with a small volume, the specifications of the cutters 31 are uniform, but it is difficult to arrange guide grooves 11 corresponding to the number of cutters 31 on the workbench 1 to correspond to the cutting position of the pipe. Only one guide groove 11 through which multiple cutters 31 can pass can be arranged, so that a through groove structure located below the pipe is formed on the workbench 1. When multiple cutters 31 pass through the guide groove 11 and cut the thin sleeve on the pipe, the cut pipe unit is located in the through groove of the workbench 1 and is not supported, so that the cut pipe unit will directly fall off, causing damage to the pipe and reducing the yield.

[0051] Therefore, for the case that the small-size pipe cannot be cut through the bottom, in an embodiment of the present application, please refer to Figure 2 and Figure 3The pipe machining device further comprises a lower support 4, the lower support 4 is provided with a supporting plane 41 for supporting the workbench 1, and the upper support 2 is arranged on the supporting plane 41. On the one hand, the machining device adopts an upper cutting mode, that is, the cutter 31 cuts the thin sleeve on the pipe from above. On the other hand, the lower support 4 of the machining device is provided with the supporting plane 41, which can not only be used for mounting and fixing the workbench 1 and the upper support 2, but also can form a supporting plane below the workbench 1. In this way, the width of the guide groove 11 in the workbench 1 is not limited, and a plurality of cutters 31 can pass through. When machining a small-volume pipe, the pipe unit located in the middle of the pipe is cut and separated by the cutter 31, and the separated pipe unit can be supported on the workbench 1 or the supporting plane 41 of the lower support 4, so as to avoid the separated pipe unit from directly falling to the ground and being damaged, effectively ensure the yield of the pipe unit, and further improve the applicability of the machining device.

[0052] In the embodiments of the present application, please refer to Figure 2 、 Figure 3 and Figure 4 The cutting mechanism 3 further comprises a first driver 32 and a tool holder 33 for mounting the cutter 31, the first driver 32 is connected with the tool holder 33 and drives the tool holder 33 to displace the cutter 31 along the guide rail 21. The first driver 32 and the tool holder 33 can be connected through a driving shaft or a connecting belt, so that the tool holder 33 can stably displace above the workbench 1, which is beneficial to adjust the cutting depth of the cutter 31 by adjusting the height of the upper support 2 or the tool holder 33, and effectively improve the cutting precision of the cutter 31.

[0053] Preferably, please refer to Figure 1 and Figure 4 The tool holder 33 is provided with a plurality of mounting plates 34, and the plurality of mounting plates 34 all extend downward. The cutter 31 is mounted on the extended end of the mounting plate 34. The number of the mounting plates 34 on the tool holder 33 is the same as the number of the guide grooves 11 on the workbench 1, and the positions are respectively corresponding. In this way, according to the machining requirement, a corresponding number of guide grooves 11 can be selectively arranged on the workbench 1, and a corresponding number of cutters 31 can be arranged for cutting operation. The machining device can complete the multi-group cutting of the pipe in one cutting, so as to cut the pipe into a plurality of pipe units in batches, and effectively improve the production efficiency. In addition, the length of the downward extension of the mounting plate 34 can be adjusted to adjust the cutting depth of the cutter 31 and improve the cutting precision of the cutter 31.

[0054] In actual application, the cutting mechanism 3 drives the cutter 31 to move on the workbench 1 to cut the tube bank placed on the workbench 1. During the cutting process, the cutter 31 is prone to push and displace the tube bank placed on the workbench 1, which causes the cutting position to change and the cutting precision to decrease. Therefore, in an embodiment of the present application, referring to Figure 1 and Figure 5 , the support plane 41 of the lower support 4 is further provided with a limiting mechanism 5 for preventing the tube bank from being displaced during cutting. The limiting mechanism 5 comprises an abutting piece 51 for abutting against the tube bank. During cutting, the cutting mechanism 3 is displaced towards the direction where the abutting piece 51 is located, so that the abutting piece 51 can abut against the tube bank placed on the workbench 1 in the moving direction of the cutter 31, effectively preventing the tube bank from being pushed and displaced by the cutter 31 during cutting, and further ensuring the cutting precision of the tube bank.

[0055] Preferably, referring to Figure 1 and Figure 5 , the limiting mechanism 5 further comprises a fixing seat 52 selectively connected with the abutting piece 51, which is selectively installed on the support plane 41 of the lower support 4. The fixing seat 52 is connected with the abutting piece 51 integrally to abut against the tube bank together, effectively improving the support strength and further improving the fixing effect of the tube bank.

[0056] Among them, referring to Figure 5 , the support plane 41 of the lower support 4 has a plurality of adjusting holes 42, and the fixing seat 52 and the abutting piece 51 are both provided with mounting holes 53 for fasteners to pass through to adjust the fixed position of the fixing seat 52 and the abutting piece 51 on the support plane 41, so as to adapt to different sizes of the tube bank placed on the workbench 1, effectively improving the adaptability.

[0057] In an embodiment of the present application, referring to Figure 3 , Figure 6 and Figure 7 , the tube bank processing device further comprises a bending mechanism for bending the tube bank placed on the workbench 1. The bending mechanism comprises an upper pressing assembly 6 and a lower pressing assembly 7. The upper pressing assembly 6 is arranged on the upper support 2 and can be lowered to be installed on the tube bank on the workbench 1. The lower pressing assembly 7 is arranged on the lower support 4. The upper pressing assembly 6 and the lower pressing assembly 7 are positionally corresponding and can clamp and bend the tube bank from top to bottom. It can be seen that the processing device of the present application also integrates the bending mechanism for bending the tube bank. The bending mechanism is composed of the upper pressing assembly 6 and the lower pressing assembly 7. The upper pressing assembly 6 and the lower pressing assembly 7 clamp and bend the tube bank unit that needs to be bent, so that the connected tube bank unit can form a bent tube bank piece. The bent tube bank piece can increase the heat dissipation area, which can not only improve the heat dissipation effect, but also reduce the occupied space, which is conducive to adapting to the installation requirements of the equipment.

[0058] Wherein, please refer to Figure 6 And Figure 7 The upper pressing assembly 6 comprises a second driver 61, a pressing plate 62, a movable plate 63 and a lifting mechanism 8, the pressing plate 62 is connected with the lifting mechanism 8, and the lifting mechanism 8 can drive the pressing plate 62 to move up and down. The movable plate 63 is connected with the pressing plate 62 through a rotating shaft, and a linkage member 614 is connected between the movable plate 63 and the second driver 61, and the second driver 61 can drive the movable plate 63 to make a bending movement from above to press against the pipe.

[0059] Correspondingly, the lower pressing assembly 7 comprises a third driver 71 and a supporting plate 72, and the supporting plane 41 of the lower support 4 is provided with a connecting seat 43 and a through slot 44 for the movement of the supporting plate 72. The supporting plate 72 is located in the through slot 44 and is connected with the connecting seat 43 through a rotating shaft. The driving shaft of the third driver 71 is connected with the supporting plate 72 and drives the supporting plate 72 to make a bending movement from below to support the pipe.

[0060] In actual application, the pipe unit to be bent is not completely cut off by the cutter 31 to obtain two pipe units connected with each other. Among the two pipe units connected with each other, one pipe unit is located on the workbench 1, and the other pipe unit is located outside the workbench 1 and is supported by the supporting plate 72 of the lower pressing assembly 7. In this way, the lifting mechanism 8 of the upper pressing assembly 6 drives the pressing plate 62 and the movable plate 63 to move downward, so that the pressing plate 62 is pressed on the pipe unit located on the workbench 1, and the movable plate 63 clamps the pipe unit located outside the workbench 1 with the supporting plate 72 of the lower pressing assembly 7. Then, the second driver 61 and the third driver 71 are synchronously driven, the second driver 61 drives the movable plate 63 to rotate downward, and the third driver 71 also drives the supporting plate 72 to rotate downward, so that the movable plate 63 and the supporting plate 72 bend the pipe unit from top to bottom to make the two pipe units connected with each other into a bent pipe body.

[0061] Wherein, please refer to Figure 7 The lifting mechanism 8 of the upper pressing assembly 6 comprises a fifth driver 81, a fixed frame 82 and a guide rod 83, the fixed frame 82 is arranged on the upper support 2, the fixed frame 82 is provided with a positioning hole 84, and the guide rod 83 is connected with the pressing plate 62 through the positioning hole 84. The fifth driver 81 is arranged on the fixed frame 82, the driving shaft of the fifth driver 81 is connected with the pressing plate 62 and drives the pressing plate 62 to move up and down along the guide rod 83. It can be seen that the lifting mechanism 8 is a screw lifting mechanism composed of the fifth driver 81, the fixed frame 82 and the guide rod 83, which effectively improves the lifting stability of the upper pressing assembly 6. The pressing plate 62 and the movable plate 63 can be accurately pressed on the corresponding pipe unit, and the machining precision is effectively improved.

[0062] In actual application, the end of each tube unit is connected with a connecting plate (not shown in the figure), and the connecting part between the adjacent connecting plates is provided to keep the adjacent tube units as a whole. However, since the connecting plate is generally a metal plate structure, and the connecting part between the adjacent connecting plates is a metal piece, the rigidity of the connecting part leads to the difficulty in bending during the bending operation. If the bending is forced, the force of the bending will be concentrated on the tube unit, which leads to the easy damage of the tube unit. Therefore, in one embodiment of the present application, please refer to Figure 3 and Figure 8 the tube processing device further comprises a abutting mechanism 9 for deforming the connecting part between the adjacent connecting plates, and the abutting mechanism 9 comprises a fourth driver 91 and a movable piece 92, and the movable piece 92 is provided with a needle 93. As shown in Figure 8 the driving shaft of the fourth driver 91 is connected with the movable piece 92, and the movable piece 92 is driven to move to the connecting plate (not shown in the figure) to make the needle 93 abut on the connecting part (not shown in the figure) between the adjacent connecting plates to press the connecting part. The connecting part between the adjacent connecting plates is deformed when the upper pressing assembly 6 and the lower pressing assembly 7 bend the tube unit, thereby reducing the stress of the tube unit, so that the connected tube units can be smoothly bent, and the tube unit is effectively protected.

[0063] In the tube processing device of the present application, the first driver 32, the second driver 61, the fifth driver 81, the third driver 71 and the fourth driver 91 can preferably adopt a driving motor or a driving cylinder to provide the output power.

[0064] The above only describes the preferred embodiments of the present application, and does not limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
