Description

Technical Field

[0001] This application relates to the technical field of metal pipe processing, and particularly relates to a metal pipe forming and processing device. Background Art

[0002] When manufacturing various mechanical equipment, some equipment needs to drill holes in the already formed metal pipes, and use the drilled metal pipe fittings to connect each branch, or install components such as valves on the metal pipe fittings to control the connection of each branch.

[0003] Referring to the publication number CN116394339B, the theme name is a drilling device and its drilling process for processing a trolley case. The device limits the front and back of the pull rod on the correction component sliding cylinder by setting a fixed component sliding cylinder, reducing the offset of the pull rod during drilling. At the same time, through the setting of the correction component, it cooperates with the fixed component to limit the pull rod in the up and down directions, realizing multi-directional tightening of the pull rod and reducing the adjustment time caused by shaking during drilling.

[0004] For the above technical solution, when drilling holes in a metal pipe, it is necessary to first clamp the metal pipe and then drill holes in the metal pipe after clamping. Since the wall thickness of some metal pipes is relatively thin, when drilling holes on the surface of the metal pipe, the drilling position is prone to depression. At the same time, when drilling holes in a metal pipe with a relatively thick wall, due to the lack of internal support and the relatively large drilling force required, the drilling position of the metal pipe will also be depressed. At the same time, when drilling holes in the side wall of the metal pipe, the staff needs to manually clamp the metal pipe, and after drilling, manually drive the metal pipe to move. It is difficult to control the distance between two adjacent holes during the movement of the metal pipe. Summary of the Invention

[0005] In view of this, this application provides a metal pipe forming and processing device, aiming to solve the problem of depression at the drilling position when drilling holes in a metal pipe.

[0006] A metal pipe forming and processing device provided by this application adopts the following technical solution, including a mounting frame, a mounting plate fixedly connected to the mounting frame, and a drilling mechanism for drilling holes in the side wall of the metal pipe; a first gear is rotatably connected to the mounting frame, a first lead screw is fixedly connected to the first gear, and the first lead screw penetrates through the mounting plate. A placement groove is formed in the mounting plate, a first support block is detachably connected in the placement groove, and the first lead screw penetrates through the first support block. A second support block is rotatably connected to the first lead screw. Auxiliary air bags for abutting against the inner wall of the metal pipe are fixedly connected to both the first support block and the second support block. Liquid inlet ports for introducing liquid into the middle position between the first support block and the second support block are formed in both the mounting plate and the first support block.

[0007] Seal both ends of the metal tube with the first support block and the second support block, and fill the space between the first support block and the second support block with liquid through the liquid inlet.

[0011] By driving the first lead screw and the second lead screw to rotate synchronously, the second support block and the clamping mechanism can move synchronously. During the movement, holes are punched in the side wall of the metal tube, which can reduce the depression during punching caused by the relatively thin wall thickness of the metal tube. At the same time, through the extrusion of the liquid inside the metal tube by the second support block, a certain degree of support force can be provided inside the metal tube, reducing the deformation of the side wall of the metal tube caused by direct punching.

[0012] Optionally, air inlets for inflating the airbag are arranged on both the first support block and the second support block.

[0013] Optionally, a connecting rod is fixedly connected in the placement groove, and the connecting rod is used to prevent the second support block from rotating when moving upward.

[0014] Through the arrangement of the connecting rod, the rotation of the second support block during the rising process can be reduced, and at the same time, the winding of the air inlet pipe for ventilating the air inlet can be reduced, increasing the continuous operation efficiency of the cutting device.

[0015] Optionally, the punching mechanism includes a pushing cylinder fixedly connected to the clamping block. A connecting block is fixedly connected to the output shaft of the pushing cylinder. A hollow punching hole is fixedly connected to the connecting block. A pushing block is slidably connected in the connecting block. The pushing block is used to push the cutting material inside the hollow punching hole. A blocking spring is fixedly connected to the connection between the pushing block and the connecting block.

The pushing rod is used to push the pushing block to move closer to the hollow punching hole when the pushing cylinder retracts.

[0016] By discharging the cutting material generated during the punching process, the situation where the cutting material directly falls into the metal tube can be reduced. At the same time, the damage caused to the inside of the metal tube by the throwing of the cutting material can be reduced.

[0017] Optionally, a dropping groove for dropping the cutting material is provided on the connecting block.

[0018] By introducing liquid into the metal tube, the damage to the metal tube caused by excessive cutting temperature during punching can be reduced. At the same time, the liquid can be used to cool the hollow punching hole, enhancing the continuous operation duration of the device.

[0019] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0020] 1. The two ends of the metal tube are blocked by the first support block and the second support block, and liquid is filled by introducing it into the space between the first support block and the second support block through the liquid inlet.

Detailed Description of the Invention

[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the Figures 1 - 8 of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art shall fall within the scope of protection of the present application.

[0034] As Figure 1As shown in the figure, this embodiment provides a metal pipe forming and processing device, which includes: a transmission mechanism, a clamping mechanism 5, a support mechanism, and a punching mechanism 2. The outer sidewall of the metal pipe to be processed is clamped by the clamping mechanism 5, and after clamping, the inner sidewall of the metal pipe to be processed is supported by the support mechanism to reduce the depression during cutting. The transmission mechanism drives the clamping mechanism 5 and the support mechanism to move, and during this process, drives the support mechanism and the clamping mechanism 5 to move synchronously. The punching mechanism 2 is arranged on the clamping mechanism 5, and during the movement of the clamping mechanism 5, the punching mechanism 2 punches the sidewall of the metal pipe to be processed. By supporting the inner sidewall of the metal pipe to be processed by the support mechanism, the depression when the punching mechanism 2 punches the outer sidewall of the metal pipe to be processed is reduced. At the same time, through the setting of the synchronization mechanism, the distance between two adjacent holes during punching is more fixed.

[0035] As Figure 1 and Figure 4 shown, the mounting frame 1 is placed on a horizontal plane, and the mounting plate 11 is fixedly connected to the sidewall of the mounting frame 1 on the side away from the horizontal plane. A storage groove 32 is formed on the mounting plate 11. The storage groove 32 is circularly arranged and is set according to the diameter of the outer sidewall of the metal pipe.

[0036] As Figure 2 and Figure 4 shown, the transmission mechanism includes: a rotating motor 4, a first gear 3, a second gear 41, a third gear 43, a first lead screw 31, and a second lead screw 42. The rotating motor 4 is fixedly connected to the side of the mounting plate 11 close to the horizontal plane. A second gear 41 is fixedly connected to the output shaft of the rotating motor 4. The first gear 3 and the third gear 43 are rotatably connected to the side of the mounting plate 11 close to the horizontal plane, and the first gear 3 and the third gear 43 can be meshed with the second gear 41. The first lead screw 31 is fixedly connected to the first gear 3 and penetrates through the mounting frame 1 and the mounting plate 11. The second lead screw 42 is fixedly connected to the third gear 43 and penetrates through the mounting frame 1. The clamping mechanism 5 is arranged on the second lead screw 42. By rotating the rotating motor 4, the second gear 41 is driven to rotate. The second gear 41 transmits the torsional force to the first gear 3 and the third gear 43. The first gear 3 and the third gear 43 rotate, driving the first lead screw 31 and the second lead screw 42 to rotate synchronously. During this process, the second lead screw 42 drives the clamping mechanism 5 to move up and down to adapt to the punching of different positions by the punching mechanism 2.

[0037] As Figure 1 , Figure 4 , Figure 6 and Figure 7As shown in the figure, the support mechanism includes: a first support block 33, a second support block 34, and an auxiliary airbag 35. The first support block 33 is detachably connected to the storage groove 32. The second support block 34 is rotatably connected to the first lead screw 31. There are two auxiliary airbags 35, and the two auxiliary airbags 35 are respectively fixedly connected to the first support block 33 and the second support block 34. The diameter of the auxiliary airbag 35 after inflation is the same as the inner diameter of the metal tube. Air inlets 6 for ventilating the auxiliary airbag 35 are provided on both the first support block 33 and the second support block 34. Liquid inlets 36 are provided on the first support block 33 and the mounting plate 11, and the liquid inlets 36 communicate to the middle position between the first support block 33 and the second support block 34. A connecting rod 61 is fixedly connected in the storage groove 32. The connecting rod 61 is used to block the rotation of the second support block 34 when it moves upward. The first lead screw 31 and the second support block 34 move away from the first support block 33, and liquid is introduced into the liquid inlet 36. When the second support block 34 and the liquid move to the end of the metal tube away from the first support block 33, gas is introduced into the auxiliary airbag 35 to make the auxiliary airbag 35 expand, store the liquid, and support the inner wall of the metal tube at the same time.

[0038] As Figure 2 , Figure 3 and Figure 5 shown in the figure, the clamping mechanism 5 includes: a sliding plate 51, a clamping motor 52, a bidirectional lead screw 53, and clamping blocks 54. The sliding plate 51 is slidably connected to the second lead screw 42, and the sliding plate 51 can move closer to and away from the mounting frame 1 when the second lead screw 42 rotates forward and backward. The clamping motor 52 is fixedly connected to the sliding plate 51. The bidirectional lead screw 53 is fixedly connected to the output shaft of the clamping motor 52. There are two clamping blocks 54, and both are rotatably connected to the bidirectional lead screw 53. By rotating the bidirectional lead screw 53, the two clamping blocks 54 can be driven to move closer to and away from each other. Clamping grooves 55 for clamping the outer wall of the metal tube are provided on the clamping blocks 54. The clamping motor 52 drives the bidirectional lead screw 53 to rotate, so that the two clamping blocks 54 move closer to each other, and the clamping grooves 55 on the clamping blocks 54 clamp the metal tube.

[0039] As Figure 5 and Figure 8As shown in the figure, the punching mechanism 2 includes: a pushing cylinder 21, a connecting block 22, a hollow punching hole 23, a pushing block 24, a blocking spring 25 and a pushing rod 26. The pushing cylinder 21 is fixedly connected to the clamping block 54, the connecting block 22 is fixedly connected to the output shaft of the pushing cylinder 21, the hollow punching hole 23 is fixedly connected to the connecting block 22, the pushing block 24 is slidably connected in the connecting block 22, one end of the pushing block 24 is arranged in the hollow punching hole 23, the pushing block 24 can approach and move away from the hollow punching hole 23. A blocking spring 25 is fixedly connected to the connecting block 22, and one end of the blocking spring 25 is fixedly connected to the pushing block 24 and the other end is fixedly connected to the connecting block 22. A pushing rod 26 is fixedly connected to the pushing cylinder 21. When the output end of the pushing cylinder 21 retracts, the pushing rod 26 can extend into the connecting block 22 and abut against the pushing block 24. The pushing cylinder 21 drives the hollow punching hole 23 to punch the outer side wall of the metal pipe. The cuttings after punching move into the hollow punching hole 23 under the push of the liquid pressure. When the pushing cylinder 21 retracts, the pushing rod 26 pushes the pushing block 24 to move, and the pushing block 24 pushes the impurities in the hollow punching hole 23 to fall off.

[0040] As Figure 8 shown, a dropping groove 7 is formed in the connecting block 22. The dropping groove 7 is used to receive the cuttings pushed out by the pushing block 24 in the hollow punching hole 23.

[0041] When this application is in use, the metal pipe needs to be placed in the placing groove 32 first, and the rotating motor 4 is started to drive the second gear 41 to rotate. The rotation of the second gear 41 drives the first gear 3 and the third gear 43 to rotate. The first lead screw 31 and the second lead screw 42 fixedly connected to the first gear 3 and the third gear 43 rotate, driving the sliding plate 51 and the second support block 34 to move. During this process, gas is introduced into the auxiliary airbag 35 on the first support block 33 to expand the auxiliary airbag 35 and seal the connection between the metal pipe and the placing groove 32. At this time, liquid is introduced into the liquid inlet 36 to make the liquid flow into the position between the first support block 33 and the second support block 34. When the second support block 34 and the sliding block move to the top position of the metal pipe, the auxiliary airbag 35 on the second support block 34 is inflated through the air inlet 6, so that the auxiliary airbag 35 on the first support block 33 and the auxiliary airbag 35 on the second support block 34 store the liquid in the middle position. During this process, the liquid completely fills the middle position between the first support block 33 and the second support block 34. The clamping motor 52 is started to drive the two clamping blocks 54 to approach each other by the bidirectional lead screw 53 fixedly connected to the output shaft of the clamping motor 52, and the clamping groove 55 on the clamping block 54 clamps the outer side wall of the metal pipe.

[0042] After clamping, reverse the rotation motor 4 so that the rotation motor 4 drives the first lead screw 31 and the second lead screw 42 to rotate in reverse. During this process, the sliding plate 51 and the second support block 34 are driven to move downward. During the downward movement of the second support block 34, the liquid located between the first support block 33 and the second support block 34 is further compacted.

[0043] When the sliding plate 51 moves to the position where punching is required, start the pushing cylinder 21 so that the pushing cylinder 21 drives the connecting block 22 to move. The hollow punching hole 23 fixedly connected to the connecting block 22 moves to the outer side wall of the metal pipe and punches the metal pipe during the continuous movement. The cutting material after the punching process moves into the hollow punching hole 23 under the push of the liquid pressure and is stored in the hollow punching hole 23. The pushing cylinder 21 retracts, driving the connecting block 22 to retract. The push rod 26 pushes the pushing block 24 towards the middle position of the hollow punching hole 23 and pushes out the cutting material in the hollow punching hole 23. The cutting material falls into the dropping groove 7. Start the rotation motor 4 again to drive the sliding plate 51 to continue moving to the next punching position for punching.

[0044] In this embodiment, by filling the inside of the metal pipe, the filler supports the inside of the metal pipe with a relatively thin wall, avoiding the deformation or collapse of the side wall of the metal pipe caused by the drive of the punching mechanism 2. At the same time, the filler can make the wall thickness of the metal pipe more uniform, so as to obtain a more accurate and uniform hole diameter during punching.

[0045] In this embodiment, using liquid to fill the inside of the metal pipe can discharge the cutting material generated during the punching process, reduce the damage to the inside of the metal pipe caused by the cutting material directly entering the inside of the metal pipe, and protect the inside of the metal pipe.

[0046] In this embodiment, due to the synchronous movement of the second support block 34 and the clamping mechanism 5, when the clamping mechanism 5 clamps the metal pipe, there is support inside the metal pipe, reducing the deformation or collapse of the side wall of the metal pipe caused by the offset of the clamping.

[0047] In this embodiment, through the synchronous movement of the first lead screw 31 and the second lead screw 42, the synchronous movement of the second support block 34 and the punching mechanism 2 can be driven, enabling uniform punching of the side wall of the metal pipe, improving production efficiency. At the same time, the moving distance can be accurately controlled to ensure the uniform distribution of the hole positions on the cylindrical object and improve the processing quality.

[0048] In the embodiment of the present application, the implementation principle of a metal tube forming and processing device is as follows: First, the metal tube needs to be placed in the placement groove 32, and the rotation motor 4 is started to drive the second gear 41 to rotate. The rotation of the second gear 41 drives the first gear 3 and the third gear 43 to rotate. The first lead screw 31 and the second lead screw 42 fixedly connected to the first gear 3 and the third gear 43 rotate, driving the sliding plate 51 and the second support block 34 to move. During this process, gas is introduced into the auxiliary airbag 35 on the first support block 33 to expand the auxiliary airbag 35 and seal the connection between the metal tube and the placement groove 32. At this time, liquid is introduced into the liquid inlet 36, and the liquid flows into the position between the first support block 33 and the second support block 34. When the second support block 34 and the sliding block move to the top position of the metal tube, the auxiliary airbag 35 on the second support block 34 is inflated through the air inlet 6, so that the auxiliary airbag 35 on the first support block 33 and the auxiliary airbag 35 on the second support block 34 store the liquid in the middle position. During this process, the liquid completely fills the middle position between the first support block 33 and the second support block 34. Then, the clamping motor 52 is started, and the bidirectional lead screw 53 fixedly connected to the output shaft of the clamping motor 52 drives the two clamping blocks 54 to approach each other, and the clamping grooves 55 on the clamping blocks 54 clamp the outer wall of the metal tube.

[0049] After clamping, reverse the rotation motor 4 to drive the first lead screw 31 and the second lead screw 42 to reverse. During this process, the sliding plate 51 and the second support block 34 are driven to move downward. During the downward movement of the second support block 34, the liquid located between the first support block 33 and the second support block 34 is further compacted.

[0050] When the sliding plate 51 moves to the position where punching is required, the pushing cylinder 21 is started to drive the connecting block 22 to move. The hollow punching head 23 fixedly connected to the connecting block 22 moves to the outer wall of the metal tube and punches the metal tube during continuous movement. The cutting material after punching moves into the hollow punching head 23 under the push of the liquid pressure and is stored in the hollow punching head 23. The pushing cylinder 21 retracts, driving the connecting block 22 to retract. The push rod 26 pushes the pushing block 24 towards the middle position of the hollow punching head 23 and pushes out the cutting material in the hollow punching head 23. The cutting material falls into the dropping groove 7. Then, the rotation motor 4 is started again to drive the sliding plate 51 to continue moving to the next punching position for punching.

[0051] In addition, it should be noted that in the description of the present application, unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0052] The above are the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present application, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present application.
