Description

Technical Field

[0001] This invention relates to the field of catheter flaring technology, specifically to an aluminum tube flaring limiting device. Background Technology

[0002] Venting is a crucial step in the manufacturing of flared catheters. Currently, flaring molds only serve to clamp and secure the catheter during flaring, failing to control the flaring length. This reliance on worker experience leads to inconsistent flaring results and severely impacts the overall quality of the flared catheters.

[0003] In the prior art, a catheter flaring clamp with a limiting function, disclosed in publication number "CN208662292U", is used in conjunction with a flaring device to flare the end of a catheter. The catheter flaring clamp includes a clamping base with a through hole A and a limiting device located between the clamping base and the flaring device. The end face of the clamping base near the limiting device is a reference surface. The limiting device includes a limiting plate, a fixing pin, and a support base. The limiting plate, which is hinged to the fixing pin at one end, rotates around the fixing pin as a pivot and crosses the opening of the through hole A to rest on the support base. At this time, the plane of the limiting plate facing the reference surface is the limiting surface. The distance between the reference surface and the limiting surface corresponds to the length of the catheter protruding during flaring. This solves the problem of poor consistency in catheter flaring processing in the prior art. It effectively limits the length of the catheter protruding from the clamping mold, ensuring the consistency of catheter flaring processing. It eliminates the need for workers to adjust the position of the catheter in the clamping mold based on experience, which can significantly improve production efficiency.

[0004] However, existing technologies still have significant drawbacks. For example, when limiting the catheter, the limiting plate needs to be manually flipped to block the catheter, and when flaring the catheter, the limiting plate needs to be manually flipped to move it away from the catheter. This means that workers need to manually control the position of the limiting plate, which is inefficient. In addition, dirt and debris inside the catheter and the temperature rise during catheter flaring can all adversely affect the flaring process. The aforementioned technologies lack corresponding mechanisms to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum tube flaring and limiting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An aluminum tube flaring and limiting device includes an aluminum tube clamp for holding the aluminum tube, a flaring device that approaches the aluminum tube clamp under the drive of a linear drive electric cylinder to flare the aluminum tube, a blower, and a limiting baffle located between the flaring device and the aluminum tube clamp and slidably arranged up and down. The flaring device is fixedly connected to a sliding guide rail that extends to the bottom of the limiting baffle and supports it. The end of the sliding guide rail extending toward the limiting baffle is inclined downward, and the sliding guide rail slides toward the limiting baffle to push the limiting baffle upward away from the aluminum tube.

[0008] The blower's blower end is connected to the air inlet end of a three-way valve via a blower pipe. The first and second air outlet ends of the three-way valve are respectively equipped with a first air outlet pipe and a second air outlet pipe. The end of the first air outlet pipe away from the three-way valve extends to the end of the aluminum tube near the limiting baffle, and the end of the second air outlet pipe away from the three-way valve extends to the outer wall of the limiting baffle. The limiting baffle has a blower channel with an air inlet opening and an air outlet opening at its two ends. When the limiting baffle blocks the aluminum tube, the air inlet opening of the blower channel is aligned and connected with the second air outlet pipe, and the air outlet opening is aligned and connected with the inner cavity of the aluminum tube. A touch switch is installed on the second air outlet pipe that is pressed and cooperates with the limiting baffle. When the touch switch is pressed by an external force, it switches the connection between the air inlet end and the first air outlet end to the connection between the air inlet end and the second air outlet end, and the limiting baffle moves upward to move away from the second air outlet pipe and the touch switch.

[0009] Preferably, the first air outlet pipe and the second air outlet pipe are both located below the end of the aluminum pipe near the limiting baffle, and the first air outlet pipe extends upward to the bottom of the aluminum pipe, and the second air outlet pipe extends to slide against the lower part of the outer side wall of the limiting baffle near the aluminum pipe clamp. The air inlet and air outlet of the blower channel are both located on the outer side wall of the limiting baffle near the aluminum pipe clamp, and the air inlet is located below the air outlet.

[0010] Preferably, the pressure switch and the three-way valve are electrically connected by a wire.

[0011] Preferably, an elastic collar is fixedly connected to the end of the second air outlet pipe away from the three-way valve.

[0012] Preferably, the limiting baffle has vertically arranged guide grooves on both sides, and guide blocks that slide into the guide grooves are fixedly arranged on both the left and right sides of the limiting baffle.

[0013] Preferably, a rolling pulley is installed at the lower end of the limiting baffle.

[0014] Preferably, the linear drive electric cylinder is equipped with an electric cylinder base on its outer side, and the electric cylinder base includes a placement plate installed below the linear drive electric cylinder, a guide plate through which the output end of the linear drive electric cylinder passes, and a connecting side plate fixedly connected between the placement plate and the guide plate.

[0015] Preferably, a guide bearing is installed on the guide plate, and the output end of the linear drive electric cylinder slides through the guide bearing.

[0016] Preferably, the output end of the linear drive electric cylinder and the flaring device are fixedly connected by a flaring device connecting plate, and the end of the sliding guide rail near the linear drive electric cylinder is fixedly connected to the flaring device connecting plate, and there are two sliding guide rails that lift the limiting baffle and are symmetrically arranged about the flaring device.

[0017] Preferably, a mounting base plate is fixedly installed below the flaring device, and the aluminum tube clamp and the linear drive electric cylinder are both fixedly installed on the mounting base plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The aluminum tube flaring limiting device of the present invention, through the setting of a sliding guide rail, enables a limiting baffle to limit and block the aluminum tube before flaring, and causes the limiting baffle to move upward away from the aluminum tube during flaring to facilitate the flaring process. This automates the blocking or repositioning of the limiting baffle from the aluminum tube, eliminating the need for manual movement of the limiting baffle and significantly improving the efficiency of aluminum tube flaring. Through the coordinated arrangement of a three-way valve, a first air outlet pipe, and a second air outlet pipe, the second air outlet pipe blows air into the aluminum tube through a blower channel to remove dust and debris before flaring, and the first air outlet pipe blows air into the aluminum tube during flaring to enhance heat dissipation and cooling. This avoids the problems of dirt and debris inside the aluminum tube and temperature rise during flaring that adversely affect the flaring process. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides a technical solution:

[0028] Example 1

[0029] An aluminum tube flaring and limiting device includes an aluminum tube clamp 1 for clamping an aluminum tube 2 and a flaring device 3 that approaches the aluminum tube clamp 1 under the drive of a linear drive electric cylinder 4 to flare the aluminum tube 2. Both the aluminum tube clamp 1 and the flaring device 3 can be existing equipment, which will not be described in detail here. A limiting baffle 5 that is slidably arranged up and down is located between the flaring device 3 and the aluminum tube clamp 1. The flaring device 3 is fixedly connected to a sliding guide rail 6 that extends below the limiting baffle 5 and supports it. The end of the sliding guide rail 6 that extends toward the limiting baffle 5 is inclined downward.

[0030] Before flaring the aluminum tube 2, the flaring device 3 is driven away from the limiting baffle 5 by the linear drive electric cylinder 4. The flaring device 3 drives the sliding guide rail 6 away from the limiting baffle 5, so that the lowest end of the sliding guide rail 6 is located below the limiting baffle 5 and supports the limiting baffle 5. At this time, the limiting baffle 5 is horizontally aligned with the aluminum tube clamp 1. The aluminum tube 2 is passed through the aluminum tube clamp 1 in the direction close to the limiting baffle 5, and the end of the aluminum tube 2 close to the limiting baffle 5 is pressed against the limiting baffle 5, so that the limiting baffle 5 limits the aluminum tube 2, thereby limiting the extension length of the aluminum tube 2. Then the aluminum tube clamp 1 is tightened to clamp the aluminum tube 2.

[0031] When flaring the aluminum tube 2, the linear drive electric cylinder 4 drives the flaring device 3 to slide towards the aluminum tube clamp 1. The flaring device 3 also drives the sliding guide rail 6 to slide towards the aluminum tube clamp 1. This causes the sliding guide rail 6 to push up the limiting baffle 5 during the sliding process. The limiting baffle 5 moves upward away from the aluminum tube 2, and the flaring device 3 continues to slide towards the aluminum tube clamp 1 until the flaring part of the flaring device 3 is inserted into the aluminum tube 2. This flaring operation is performed on the aluminum tube 2. Compared with the existing technology, which requires... To allow manual rotation of the limiting plate to block or move away from the guide tube, this embodiment uses the cooperation of the sliding guide rail 6 and the limiting baffle 5 to automatically block the aluminum tube 2 before it is flared, thus limiting the aluminum tube 2. When the aluminum tube 2 is flared, the sliding guide rail 6 pushes the limiting baffle 5 upward away from the aluminum tube 2, making it easier for the flaring device 3 to insert into the aluminum tube 2 for flaring. This automates the blocking or moving of the limiting baffle 5 from the aluminum tube 2, greatly improving the efficiency of aluminum tube flaring.

[0032] As one implementation, a mounting base plate 15 is fixedly installed below the flaring device 3, and the aluminum tube clamp 1 and the linear drive cylinder 4 are both fixedly installed on the mounting base plate 15. Specifically, the linear drive cylinder 4 and the aluminum tube clamp 1 are installed on the upper surface of the mounting base plate 15 at left and right intervals. The limiting baffle 5 is located between the linear drive cylinder 4 and the aluminum tube clamp 1. The flaring device 3 is located between the linear drive cylinder 4 and the limiting baffle 5. The sliding guide rail 6 extends to the right and reaches the lower end of the limiting baffle 5 to support the limiting baffle 5. The output end of the linear drive cylinder 4 extends to the right and moves in a telescopic motion in the left and right direction. This allows the sliding guide rail 6 to slide to the right along with the flaring device 3 and lift the limiting baffle 5. The flaring device 3 continues to slide to the right to insert the aluminum tube 2 for flaring operation.

[0033] Furthermore, the right end of the output of the linear drive electric cylinder 4 and the flaring device 3 are fixedly connected by the flaring device connecting plate 18, and the end of the sliding guide rail 6 near the linear drive electric cylinder 4 is fixedly connected to the flaring device connecting plate 18. Two sliding guide rails 6 are provided to support the limit baffle 5 and are symmetrically arranged about the flaring device 3. By providing two sliding guide rails 6 to support the limit baffle 5, the stability of the process of the sliding guide rails 6 supporting the limit baffle 5 and lifting it upwards is improved. The limit baffle 5 is open on both sides. A vertically arranged guide groove 51 is provided, and guide blocks 14 are fixedly arranged on both the left and right sides of the limiting baffle 5 and are slidably inserted into the guide groove 51. The lower end of the guide block 14 is fixedly installed on the mounting base plate 15. The cooperation between the guide block 14 and the guide groove 51 guides the limiting baffle 5 and improves the stability of the limiting baffle 5 during the up and down sliding process. A rolling pulley 52 is installed at the lower end of the limiting baffle 5. The setting of the rolling pulley 52 improves the smoothness of the sliding guide rail 6 sliding through the limiting baffle 5.

[0034] Furthermore, a cylinder base 16 is installed on the outside of the linear drive electric cylinder 4, and the cylinder base 16 includes a placement plate 161 installed below the linear drive electric cylinder 4, a guide plate 162 through which the output end of the linear drive electric cylinder 4 passes, and a connecting side plate 163 fixedly connected between the placement plate 161 and the guide plate 162. The placement plate 161 is fixedly installed on the upper surface of the mounting base plate 15. The cooperation of the placement plate 161, the guide plate 162 and the connecting side plate 163 protects the linear drive electric cylinder 4 and improves the installation stability of the linear drive electric cylinder 4. A guide bearing 17 is installed on the guide plate 162, and the output end of the linear drive electric cylinder 4 slides through the guide bearing 17. The guide bearing 17 guides the output end of the linear drive electric cylinder 4 and improves the stability of the left and right extension and retraction process of the output end of the linear drive electric cylinder 4.

[0035] Example 2:

[0036] Example 2 adds a mechanism for cleaning and cooling the aluminum tube 2 based on Example 1. This mechanism includes a blower 7 connected to the air inlet of a three-way valve 9 via a blower pipe 8. A first air outlet pipe 10 and a second air outlet pipe 11 are respectively installed at the first and second air outlets of the three-way valve 9. The end of the first air outlet pipe 10 away from the three-way valve 9 extends to the end of the aluminum tube 2 near the limiting baffle 5, and the end of the second air outlet pipe 11 away from the three-way valve 9 extends to the outer wall of the limiting baffle 5. The limiting baffle 5 has a blower channel 12 with an air inlet and an air outlet at its two ends. The second air outlet pipe 11 is equipped with a mechanism connected to the limiting baffle. 5. A pressure-operated contact switch 13 is electrically connected to a three-way valve 9 via a wire. The contact switch 13 can be a TS-1101SP type contact-type surface-mount switch. When the contact switch 13 is not subjected to external pressure, the contact switch 13 does not output a signal to the three-way valve 9, and the air inlet and the first air outlet in the three-way valve 9 are connected, so that the blower pipe 8 and the first air outlet pipe 10 are connected. When the contact switch 13 is subjected to external pressure, the contact switch 13 outputs a signal to the three-way valve 9 via a wire, so that the air inlet and the second air outlet in the three-way valve 9 are connected, so that the blower pipe 8 and the second air outlet pipe 11 are connected.

[0037] Before flaring the aluminum tube 2, the limiting baffle 5 is stabilized and abuts against the aluminum tube 2 under the support of the lowest end of the sliding guide rail 6. At this time, the air inlet end of the blower channel 12 is aligned and connected with the second air outlet pipe 11, and the air outlet end is aligned and connected with the inner cavity of the aluminum tube 2. The touch switch 13 abuts against the outer wall of the limiting baffle 5 together with the second air outlet pipe 11. The touch switch 13 is pressed by external force so that the air inlet end and the second air outlet end in the three-way valve 9 are connected. The air blown out by the blower 7 enters the blower channel 12 through the blower pipe 8, the three-way valve 9, and the second air outlet pipe 11. Finally, it enters the inner cavity of the aluminum tube 2 from the air outlet end of the blower channel 12. This blows air to clean the inner cavity of the aluminum tube 2, blowing away the dust and debris in the inner cavity of the aluminum tube 2, and avoiding the problem of adverse effects on the subsequent flaring device 3 flaring the aluminum tube 2.

[0038] When the aluminum tube 2 is flared, the sliding guide rail 6 pushes the limiting baffle 5 upward away from the aluminum tube 2. The limiting baffle 5 slides upward to move away from the second air outlet pipe 11 and the touch switch 13. The touch switch 13 is no longer subjected to external pressure and stops outputting signals to the three-way valve 9. The air inlet end and the first air outlet end in the three-way valve 9 are connected. The air blown by the blower 7 blows onto the aluminum tube 2 through the blower pipe 8, the three-way valve 9, and the first air outlet pipe 11, thereby enhancing the heat dissipation and cooling effect of the aluminum tube 2 and avoiding the problem of heat accumulating on the aluminum tube 2 when the flaring device 3 flares the aluminum tube 2, which would cause adverse effects.

[0039] In one embodiment, the first air outlet pipe 10 and the second air outlet pipe 11 are both located below the end of the aluminum pipe 2 near the limiting baffle 5. The first air outlet pipe 10 extends upward to below the end of the aluminum pipe 2 near the limiting baffle 5, and the second air outlet pipe 11 extends to slide against the lower part of the outer side wall of the limiting baffle 5 near the aluminum pipe clamp 1. The air inlet and outlet ends of the blower channel 12 are both located on the outer side wall of the limiting baffle 5 near the aluminum pipe clamp 1, and the air inlet end is located below the air outlet end. An elastic collar is fixedly connected to the end of the second air outlet pipe 11 away from the three-way valve 9. The setting of the elastic collar improves the sealing performance when the second air outlet pipe 11 and the air inlet end of the blower channel 12 are aligned and connected.

[0040] Working principle: Before flaring the aluminum tube 2, the flaring device 3 is driven away from the limiting baffle 5 by the linear drive electric cylinder 4. The flaring device 3 drives the sliding guide rail 6 away from the limiting baffle 5, so that the lowest end of the sliding guide rail 6 is located below the limiting baffle 5 and supports the limiting baffle 5. At this time, the limiting baffle 5 is horizontally aligned with the aluminum tube clamp 1 and limits the aluminum tube 2. The touch switch 13 is pressed by the limiting baffle 5 so that the air inlet end and the second air outlet end in the three-way valve 9 are connected. The air blown out by the blower 7 enters the blower channel 12 through the blower pipe 8, the three-way valve 9, and the second air outlet pipe 11. Finally, it enters the inner cavity of the aluminum tube 2 from the air outlet end of the blower channel 12, thereby blowing and cleaning the inner cavity of the aluminum tube 2 and blowing away the dust and debris in the inner cavity of the aluminum tube 2.

[0041] When flaring the aluminum tube 2, the linear drive electric cylinder 4 drives the flaring device 3 to slide towards the aluminum tube clamp 1. The flaring device 3 drives the sliding guide rail 6 to slide towards the aluminum tube clamp 1 together, so that the sliding guide rail 6 pushes up the limiting baffle 5 during the sliding process. The limiting baffle 5 moves upward away from the aluminum tube 2. The flaring device 3 continues to slide towards the aluminum tube clamp 1 until the flared part of the flaring device 3 is inserted into the aluminum tube 2. This is how the aluminum tube 2 is flared. The limiting baffle 5 slides upward to move away from the second air outlet pipe 11 and the pressure switch 13. The pressure switch 13 is no longer under external pressure and stops outputting a signal to the three-way valve 9. The air inlet end of the three-way valve 9 is connected to the first air outlet end. The air blown by the blower 7 blows onto the aluminum tube 2 through the blower pipe 8, the three-way valve 9, and the first air outlet pipe 11, thereby enhancing the heat dissipation and cooling effect of the aluminum tube 2.

[0042] 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.
