Description

Technical Field

[0001] The present application relates to the technical field of metal tube processing, and in particular to a metal tube forming processing device. Background Art

[0002] When manufacturing various mechanical equipment, some equipment requires punching holes in the formed metal pipes, using the punched metal pipe fittings to connect the various branches, or installing valves and other components on the metal pipe fittings to control the connectivity of the various branches.

[0003] Referring to the announcement number CN116394339B, the subject name is a punching device for trolley case processing and its punching process. The device sets a fixed component sliding cylinder to limit the pull rod on the correction component sliding cylinder forward and backward, thereby reducing the displacement of the pull rod during drilling. At the same time, through the setting of the correction component, the fixed component is cooperated to limit the pull rod in the up and down directions, so as to achieve multi-directional tightening of the pull rod and reduce the adjustment time caused by shaking during drilling.

[0004] According to the above technical solution, when punching holes in a metal tube, the metal tube needs to be clamped first, and then the metal tube is punched after clamping. Since the wall of some metal tubes is thin, the punching position is prone to depression when the metal tube surface is punched. At the same time, when punching holes in a metal tube with a thick wall, due to the lack of internal support and the large punching force required, the punching position of the metal tube will also be depressed. At the same time, when punching holes in the side wall of the metal tube, the staff is required to manually clamp the metal tube and manually move the metal tube after punching. It is difficult to control the distance between two adjacent holes during the movement of the metal tube. Summary of the invention

[0005] In view of this, the present application provides a metal tube forming processing device, which aims to solve the problem of a concave punching position when punching a metal tube.

Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0026] like Figure 1As shown, this embodiment provides a metal tube forming processing device including: a transmission mechanism, a clamping mechanism 5, a support mechanism and a punching mechanism 2. The outer side wall of the metal tube is clamped by the clamping mechanism 5, and the inner side wall of the metal tube is supported by the support mechanism after clamping to reduce the depression during cutting. The clamping mechanism 5 and the support mechanism are driven to move by the transmission mechanism, and the support mechanism and the clamping mechanism 5 are driven to move synchronously in this process. The punching mechanism 2 is arranged on the clamping mechanism 5, and the punching mechanism 2 punches the side wall of the metal tube during the movement of the clamping mechanism 5. The inner side wall of the metal tube is supported by the support mechanism to reduce the depression when the punching mechanism 2 punches the outer side wall of the metal tube. At the same time, the distance between two adjacent holes during punching can be more fixed through the setting of the synchronization mechanism.

[0027] like Figure 1 and Figure 4 As shown, the mounting frame 1 is placed on a horizontal plane, and the mounting plate 11 is fixedly connected to the side wall of the mounting frame 1 away from the horizontal plane. A storage groove 32 is provided on the mounting plate 11. The storage groove 32 is circular and fits the diameter of the outer wall of the metal tube.

[0028] like Figure 2 and Figure 4 As shown, the transmission mechanism includes: a rotating motor 4, a first gear 3, a second gear 41, a third gear 43, a first screw rod 31 and a second screw rod 42. The rotating motor 4 is fixedly connected to the side of the mounting plate 11 close to the horizontal plane, and the 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 mesh with the second gear 41. The first screw rod 31 is fixedly connected to the first gear 3 and is arranged to penetrate the mounting frame 1 and the mounting plate 11. The second screw rod 42 is fixedly connected to the third gear 43 and is arranged to penetrate the mounting frame 1. The second screw rod 42 is provided with a clamping mechanism 5. The second gear 41 is driven to rotate by the rotation of the rotating motor 4, and 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 screw rod 31 and the second screw rod 42 to rotate synchronously. During this process, the second screw rod 42 drives the clamping mechanism 5 to move up and down to adapt to the punching mechanism 2 to punch holes in different positions.

[0029] like Figure 1 , Figure 4 , Figure 6 and Figure 7As shown, the support mechanism includes: a first support block 33, a second support block 34 and an auxiliary air bag 35. The first support block 33 is detachably connected to the storage slot 32, and the second support block 34 is rotatably connected to the first screw rod 31. Two auxiliary air bags 35 are provided, and the two auxiliary air bags 35 are respectively fixedly connected to the first support block 33 and the second support block 34. The diameter of the auxiliary air bag 35 after ventilation is the same as the diameter of the inner wall of the metal tube. The first support block 33 and the second support block 34 are both provided with an air inlet 6 for ventilating the auxiliary air bag 35. The first support block 33 and the mounting plate 11 are provided with a liquid inlet 36, and the liquid inlet 36 is connected to the middle position of the first support block 33 and the second support block 34. A connecting rod 61 is fixedly connected in the storage groove 32, and the connecting rod 61 is used to prevent the second support block 34 from rotating when it moves upward. The first screw rod 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 expand the auxiliary airbag 35 to store the liquid and support the inner wall of the metal tube at the same time.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the clamping mechanism 5 includes: a sliding plate 51, a clamping motor 52, a bidirectional screw 53 and a clamping block 54, the sliding plate 51 is slidably connected to the second screw 42, and the sliding plate 51 can move closer to and away from the mounting frame 1 when the second screw 42 rotates forward and reversely, the clamping motor 52 is fixedly connected to the sliding plate 51, the bidirectional screw 53 is fixedly connected to the output shaft of the clamping motor 52, and two clamping blocks 54 are provided, and both are rotatably connected to the bidirectional screw 53, and the rotation of the bidirectional screw 53 can drive the two clamping blocks 54 to approach and depart from each other, and the clamping block 54 is provided with a clamping groove 55 that can clamp the outer wall of the metal pipe. The bidirectional screw 53 is driven to rotate by the clamping motor 52, so that the two clamping blocks 54 are brought closer to each other, and the clamping groove 55 on the clamping block 54 clamps the metal pipe.

[0031] like Figure 5 and Figure 8As shown, 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, and when the output end of the pushing cylinder 21 is recovered, the pushing rod 26 can extend into the connecting block 22 and abut against the pushing block 24. The outer wall of the metal tube is punched by driving the hollow punch 23 through the pushing cylinder 21. The punched cutting material moves into the hollow punch 23 under the push of liquid pressure. When the pushing cylinder 21 is recovered, the pushing rod 26 pushes the pushing block 24 to move, and the pushing block 24 pushes the impurities in the hollow punch 23 to fall out.

[0032] like Figure 8 As shown, a drop groove 7 is provided on the connecting block 22 , and the drop groove 7 is used to receive the cutting material pushed out by the pushing block 24 in the hollow punching hole 23 .

[0033] When the present application is in use, it is necessary to first place the metal tube in the storage groove 32, and start the rotating motor 4, so that the rotating motor 4 drives the second gear 41 to rotate, and the rotation of the second gear 41 drives the first gear 3 and the third gear 43 to rotate, and the first screw rod 31 and the second screw rod 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, and in this process, gas is introduced into the auxiliary air bag 35 on the first support block 33 to expand the auxiliary air bag 35 and seal the connection between the metal tube and the storage groove 32, and at this time, liquid is introduced into the liquid inlet 36 to allow the liquid to flow into the first support block 3 3 and the second support block 34. When the second support block 34 and the sliding block move to the top 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, and in this process, the liquid is completely filled to the middle position of the first support block 33 and the second support block 34, and the clamping motor 52 is started, so that the bidirectional screw rod 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 groove 55 on the clamping block 54 clamps the outer wall of the metal tube.

[0034] After clamping, the rotating motor 4 is reversed, so that the rotating motor 4 drives the first screw rod 31 and the second screw rod 42 to reverse, and in this process, drives the sliding plate 51 and the second support block 34 to move downward, and in the process of the second support block 34 moving downward, the liquid located between the first support block 33 and the second support block 34 is further compacted.

[0035] When the sliding plate 51 moves to the position where a hole needs to be punched, the pushing cylinder 21 is started, so that the pushing cylinder 21 drives the connecting block 22 to move, and the hollow punching hole 23 fixedly connected to the connecting block 22 moves to the outer wall of the metal pipe, and the metal pipe is punched during the continuous movement. The cutting material after the punching moves to the hollow punching hole 23 under the push of liquid pressure and is stored in the hollow punching hole 23. The pushing cylinder 21 is recycled, driving the connecting block 22 to be recycled. The pushing rod 26 drives the pushing block 24 to move to the middle position of the hollow punching hole 23, and pushes out the cutting material in the hollow punching hole 23, and the cutting material falls into the drop groove 7. The rotating motor 4 is started again to drive the sliding plate 51 to continue to move to the next punching position for punching.

[0036] In this embodiment, the interior of the metal tube is filled so that the filler supports the thinner interior of the metal tube, thereby preventing the punching mechanism 2 from causing deformation or collapse of the side wall of the metal tube. At the same time, the filler can make the wall thickness of the metal tube more uniform, thereby obtaining a more accurate and uniform hole diameter when punching.

[0037] In this embodiment, liquid is used to fill the interior of the metal tube, which can discharge the cuttings generated during the punching process, reduce the direct entry of the cuttings into the interior of the metal tube, reduce the damage caused to the interior of the metal tube, and protect the interior of the metal tube.

[0038] In this embodiment, due to the synchronous movement of the second support block 34 and the clamping mechanism 5, the clamping mechanism 5 can support the inside of the metal tube when clamping the metal tube, thereby reducing deformation or collapse of the side wall of the metal tube due to clamping deviation.

[0039] In this embodiment, through the synchronous movement of the first screw rod 31 and the second screw rod 42, the second support block 34 and the punching mechanism 2 can be driven to move synchronously, so that the side wall of the metal tube can be evenly punched, thereby 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, thereby improving the processing quality.

[0040] The implementation principle of a metal tube forming processing device in the embodiment of the present application is as follows: the metal tube needs to be placed in the storage groove 32 first, and the rotating motor 4 is started, so that the rotating motor 4 drives the second gear 41 to rotate, and the rotation of the second gear 41 drives the first gear 3 and the third gear 43 to rotate, and the first screw rod 31 and the second screw rod 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, and in this process, gas is introduced into the auxiliary air bag 35 on the first support block 33 to expand the auxiliary air bag 35 and seal the connection between the metal tube and the storage groove 32, and at this time, liquid is introduced into the liquid inlet 36 to allow the liquid to flow When the second support block 34 and the sliding block move to the top 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, and in this process, the liquid is completely filled to the middle position of the first support block 33 and the second support block 34, and the clamping motor 52 is started, so that the bidirectional screw rod 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 groove 55 on the clamping block 54 clamps the outer wall of the metal tube.

[0041] After clamping, the rotating motor 4 is reversed, so that the rotating motor 4 drives the first screw rod 31 and the second screw rod 42 to reverse, and in this process, drives the sliding plate 51 and the second support block 34 to move downward, and in the process of the second support block 34 moving downward, the liquid located between the first support block 33 and the second support block 34 is further compacted.

[0042] When the sliding plate 51 moves to the position where a hole needs to be punched, the pushing cylinder 21 is started, so that the pushing cylinder 21 drives the connecting block 22 to move, and the hollow punching hole 23 fixedly connected to the connecting block 22 moves to the outer wall of the metal pipe, and the metal pipe is punched during the continuous movement. The cutting material after the punching moves to the hollow punching hole 23 under the push of liquid pressure and is stored in the hollow punching hole 23. The pushing cylinder 21 is recycled, driving the connecting block 22 to be recycled. The pushing rod 26 drives the pushing block 24 to move to the middle position of the hollow punching hole 23, and pushes out the cutting material in the hollow punching hole 23, and the cutting material falls into the drop groove 7. The rotating motor 4 is started again to drive the sliding plate 51 to continue to move to the next punching position for punching.

[0043] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
