Description

Technical Field

[0001] This invention relates to the technical field of alloy profile bending equipment, specifically to a bending and shaping mechanism for aluminum alloy tubes. Background Technology

[0002] Alloy tubing is generally a straight cylindrical structure. In certain applications, it may be necessary to bend the tubing at a specific angle. Besides breaking the tubing and reassembling it to the desired angle, current technology typically uses a bending machine for mechanical bending to achieve this. This type of equipment is usually driven by hydraulic or electric power, using a guiding mechanism and clamps to deform and bend the profile around the guiding mechanism. However, this type of equipment still has the following problems in practical use:

[0003] When processing small and medium-sized profiles, in order to ensure processing efficiency, bending efficiency and bending speed are increased accordingly. However, the molecular structure of metal is more stable. During rapid bending, the relative movement between molecules on the deformed surface generates relatively high heat, resulting in a relatively high temperature at the bent part, which is inconvenient for workers to handle manually. Summary of the Invention

[0004] The purpose of this invention is to provide a bending and shaping mechanism for aluminum alloy tubes, in order to ensure processing efficiency when processing small and medium-sized profiles, the bending efficiency and bending speed are increased accordingly. However, the molecular structure of metal is more stable, and during rapid bending, the relative movement between molecules on the deformation surface generates relatively high heat, resulting in a relatively high temperature at the bending part, which makes it inconvenient for workers to handle manually.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bending and shaping mechanism for aluminum alloy tubes, comprising a machine body and a base plate disposed above the machine body. The base plate is used to install a clamp for pushing the deformation of the profile. A vertical rod fixed at the bottom end of the base plate passes through a sliding groove opened on the upper end face of the machine body and is fixed to a movable plate. The movable plate is threadedly connected to a screw installed inside the machine body and connected to the output end of a motor. Furthermore, a guide post is also installed on the upper end face of the machine body. The guide post is used to support the profile and to form the bent portion of the profile. The guide post has an hourglass-shaped structure, and its surface has an annular groove for fluid flow. The surface of the annular groove is covered with an elastic sheet for sealing the annular groove. Simultaneously, the fluid in the annular groove is supplied via a flow mechanism.

[0006] As a further step, the flow mechanism includes a connecting pipe and a delivery pump, the delivery pump being installed in the machine body and connected to the tail end of the connecting pipe, the top end of which is connected to an annular groove.

[0007] As a further step, the flow mechanism includes a connecting pipe and a housing, which is rotatably penetrated by the tail end of a screw, and a first impeller fixed to the tail end of the screw is disposed inside the housing. The output end of the housing is connected to the bottom end of the connecting pipe, while the top end of the connecting pipe is connected to an annular groove.

[0008] As a further step, two outer shells are provided inside the machine body. The two outer shells are respectively connected to the bottom ends of two connecting pipes, and the outer shells are connected to each other through a horizontal pipe. A second impeller is provided inside the outer shell located away from the screw, which is unidirectionally rotatable on the horizontal shaft. The first impeller is also unidirectionally rotatable on the screw. The outer end of the horizontal shaft is connected to the screw through a pulley mechanism. A one-way valve is provided in the elastic connecting pipe connected to the outer shell on which the second impeller is installed.

[0009] As a further step, a clamping block is installed on the inner walls of both the front and rear sides of the fixture, and a roller is rotatably embedded in the inner wall of the clamping block, and the spacing between the clamping blocks is greater than the cross-sectional width of the profile.

[0010] As a further step, the bottom end of the clamp is rotatably connected to the top end of the vertical shaft, and the bottom end of the vertical shaft is horizontally slidably mounted on the upper end surface of the base plate by a spring.

[0011] As a further step, the inside of the roller is a hollow structure, and the hollow structure is connected to air holes on the surface of the roller. The hollow structure is connected to an air supply device, which is used to supply air into the hollow structure and blow air out from the air holes to clean the surface of the profile.

[0012] As a further step, the air supply mechanism includes a cavity and an air pipe, with the cavity communicating with the top end of the air pipe and being opened inside the clamping block and the clamp, while the bottom end of the air pipe is connected to the air cylinder.

[0013] As a further step, the air cylinder is installed in the machine body, and vertically distributed valve plates are horizontally slidably fitted inside the air cylinder. The valve plates are fixedly connected to the valve stem that is slidably sealed on the right side wall of the air cylinder. The outer end of the valve stem is fixed to the moving plate. At the same time, the air cylinder space on both sides of the valve plate is provided with a one-way input end and a one-way output end. The two output ends are respectively connected to the two forked ends of an air pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the bending and shaping mechanism of the aluminum alloy tube has been redesigned with a guide mechanism and a clamping mechanism, which can automatically realize the cooling operation at the bending point by utilizing the operation of the power mechanism during the bending process, and can realize the rapid separation of the profile by utilizing the backflow of liquid in the same equipment and water cooling mechanism, and can simultaneously and efficiently clean the profile surface to avoid damage to the profile surface caused by residual debris and squeezing contact with the profile surface.

[0015] 1. The structure of the elastic sheet and the annular groove allows the surface temperature of the profile at the bend to be dissipated quickly by the flow of water inside, avoiding the inconvenience of handling by workers due to high temperature caused by deformation.

[0016] Furthermore, the use of multiple housings and impeller structures can, on the one hand, drive the first impeller to rotate by rotating the screw clockwise, so that the liquid can circulate in the housing and annular groove to achieve liquid cooling effect; on the other hand, drive the second impeller to rotate by rotating the screw in the opposite direction, so that the liquid can accumulate in the annular groove and cause elastic sheet deformation, thereby enabling the profile to separate quickly.

[0017] 2. The structural design of the clamp and rollers can, on the one hand, utilize the rotatable setting of the clamp on the base plate to keep the clamp in contact with the profile, and on the other hand, enable the profile to vibrate and detach through the spring-loaded setting of the clamp as a whole.

[0018] Furthermore, the structural design of the valve plate, air pipe, and cavity allows the moving plate to consistently supply airflow into the cavity during movement, thereby enabling the rapid removal of debris from the profile surface. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-8 The present invention provides the following technical solution:

[0030] Example 1:

[0031] In order to solve the problems existing in the prior art, the following solution is disclosed in this embodiment, such as... Figure 1-3 As shown, the device includes a body 1 and a base plate 2 positioned above the body 1. The base plate 2 is used to mount a clamp 15 for pushing the deformation of the profile. A vertical rod 4 fixed at the bottom end of the base plate 2 passes through a groove 5 opened on the upper end face of the body 1 and is fixed to a movable plate 24. The movable plate 24 is threadedly connected to a screw 6 installed inside the body 1 and connected to the output end of a motor. A guide post 3 is also installed on the upper end face of the body 1. The guide post 3 is used to support the profile and to form the bending part of the profile. The guide post 3 has an hourglass shape and an annular groove 7 for fluid flow is opened on its surface. The surface of the annular groove 7 is covered with an elastic sheet 8 for sealing the annular groove 7. At the same time, the fluid in the annular groove 7 is supplied through a flow mechanism. The profile is initially placed in... In each clamp 15, the middle part fits into the concave surface of the guide post 3. Then, the motor can be started and the screw 6 can be driven to rotate. Under the action of the threaded transmission, the moving plate 24 drives the base plate 2 and the clamp 15 to move through the vertical rod 4. The middle part of the profile is blocked by the guide post 3, and the continuous movement of the clamp 15 causes the profile to bend and deform around the guide post 3, thereby achieving the bending effect. At the same time, the flow mechanism operates accordingly, which can drive the fluid to flow in the annular groove 7, thereby cooling the bent part of the profile and making it easier for the staff to handle later. The flow mechanism includes a connecting pipe 9 and a delivery pump. The delivery pump is installed in the machine body 1 and connected to the tail end of the connecting pipe 9. The top end of the connecting pipe 9 is connected to the annular groove 7.

[0032] Example 2:

[0033] In this embodiment, an alternative, more energy-efficient and environmentally friendly cooling mechanism is disclosed, specifically as follows: Figure 3-4 As shown, unlike the pump drive in Embodiment 1, the flow mechanism includes a connecting pipe 9 and a housing 10. The housing 10 is rotatably penetrated by the tail end of the screw 6, and a first impeller 11 fixed to the tail end of the screw 6 is disposed inside the housing 10. The output end of the housing 10 is connected to the bottom end of the connecting pipe 9, and the top end of the connecting pipe 9 is connected to the annular groove 7. In this embodiment, when the screw 6 is in a rotating state... Figure 4 The first impeller 11 shown will rotate synchronously and perform fluid transport. The fluid source can be any storage device. The liquid enters the connecting pipe 9 through the outer casing 10 and then enters... Figure 2 The annular groove 7 in the middle allows the fluid to generate a cooling effect directly without the need for other electrical equipment during the bending process, thus making it more energy-efficient and environmentally friendly.

[0034] Because metal profiles have high hardness, after bending deformation, the bent portion is prone to getting stuck in the guide structure of the bending machine due to deformation at the edges. Therefore, this embodiment discloses the following solution to address this problem, specifically as follows: Figure 4 As shown, two outer shells 10 are installed inside the body 1. Each outer shell 10 is connected to the bottom end of one of the two connecting pipes 9, and the outer shells 10 are connected by a horizontal pipe 12. A second impeller 14 is installed inside the outer shell 10 located away from the screw 6. It is unidirectionally mounted on the horizontal shaft 13, while the first impeller 11 is also unidirectionally mounted on the screw 6. The outer end of the horizontal shaft 13 is connected to the screw 6 via a pulley mechanism. A one-way valve is installed in the elastic connecting pipe 9 connected to the outer shell 10 with the second impeller 14. When the profile bending is complete and needs to be removed from the device, the screw 6 can rotate in the opposite direction. At this time, the first impeller 11 will not rotate, but the horizontal shaft 13 will drive the second impeller 14 to rotate under the pulley mechanism. Therefore, when the second impeller 14 rotates, the lower half of the one-way valve in the connecting pipe 9 connected to the outer shell 10 will be deformed, squeezing out the liquid inside that section of the connecting pipe 9 and transporting it to the other outer shell 10. Figure 4 As shown, the connecting pipe 9 on the left enters the annular groove 7. At this time, the elastic sheet 8 will expand accordingly and spring the profile away, thereby achieving the effect of the deformed profile automatically separating from the guide structure.

[0035] Example 3:

[0036] This embodiment discloses another mechanism for disengaging the auxiliary profile from the device. A clamping block 16 is installed on the inner walls of both the front and rear sides of the clamp 15. A roller 18 is rotatably embedded in the inner wall of the clamping block 16, and the spacing between the clamping blocks 16 is greater than the cross-sectional width of the profile. The bottom end of the clamp 15 is rotatably connected to the top end of the vertical shaft 17, and the bottom end of the vertical shaft 17 is horizontally slidably mounted on the upper surface of the base plate 2 via a spring. Specifically, as shown... Figure 5 As shown, when the clamp 15 pushes the profile to bend and deform, the vertical shaft 17 at the bottom of the clamp 15 will elastically slide above the base plate 2, and the entire clamp 15 will also rotate at the top of the vertical shaft 17, so that the inner wall of the clamping block 16 on the clamp 15, which is in direct contact with the surface of the profile, can maintain its fit with the profile. After the profile is bent, the base plate 2 drives the clamp 15 to move in the opposite direction. At this time, the clamp 15 springs back accordingly, and the return movement of the clamp 15 makes... Figure 5 The clamping block 16 on the other side shown can strike the other side surface of the profile, thereby achieving the effect of vibration release.

[0037] In this embodiment, in order to simultaneously clean the surface of the profile, the following solution is also disclosed, specifically as follows: Figure 6-8 As shown, the interior of the roller 18 is a hollow structure, and this hollow structure is connected to air holes on the surface of the roller 18. The hollow structure is connected to an air supply device, which supplies air into the hollow structure and blows the air out through the air holes to clean the surface of the profile. The air supply mechanism includes a cavity 19 and an air pipe 20. The cavity 19, which is connected to the top of the air pipe 20, is located inside the clamping block 16 and the clamp 15. The bottom end of the air pipe 20 is connected to the air cylinder 21, which is installed in the machine body 1. Vertically distributed valve plates 22 are horizontally slidably mounted inside the air cylinder 21. The valve plates 22 are fixedly connected to the valve stem 23, which is slidably sealed to the right side wall of the air cylinder 21. The outer end of the valve stem 23 is fixed to the moving plate 24. On the upper part, the air cylinder 21 spaces on both sides of the valve plate 22 are provided with a one-way input end and a one-way output end. The two output ends are respectively connected to the two forked ends of an air pipe 20. The movement of the moving plate 24 will drive the valve plate 22 to move back and forth in the air cylinder 21 through the valve rod 23. When the valve plate 22 moves to the left, the space on its right side will be in a suction state, and the gas in the space on the left side will enter the cavity 19 through the air pipe 20. When the valve plate 22 moves to the right, the left side will be suctioned and the right side will be discharged. Therefore, no matter which direction of movement, the surface of the roller 18 will blow out an airflow that acts on the surface of the profile, achieving a cleaning effect. Furthermore, since the clamp 15 moves on the surface of the profile as a whole, the airflow cleaning effect is even better.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
