Description

Technical Field

[0001] This invention belongs to the field of automation equipment technology and relates to an automated capillary tube drawing device with high inner diameter precision. Background Technology

[0002] When winding capillary copper tubes containing mandrels, a winding cylinder is required. Existing capillary winding devices often result in a disordered winding pattern, requiring manual assistance to straighten and organize the coils. This process is labor-intensive and has a relatively low level of automation.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a multi-mold tube drawing machine [application number: 201620747211.6], which includes a rotating wheel, a tower wheel, and a platform. Multiple tube drawing dies are arranged in parallel on the platform. Each tube drawing die has a circular hole, and the inner diameter of the circular holes of the multiple tube drawing dies decreases sequentially for sequentially passing through a metal tube. The tower wheel has grooves corresponding to the multiple tube drawing dies, which are used to accommodate the metal tube. The metal tube passes sequentially through the rotating wheel, the grooves on the tower wheel, and the circular holes of the tube drawing dies corresponding to the grooves. Through the rotation of the rotating wheel, a microchannel metal tube is drawn. However, this solution still easily results in a messy situation when winding capillary tubes, requiring manual assistance to straighten and organize them. It suffers from high labor intensity and a relatively low degree of automation. Summary of the Invention

[0015] In the aforementioned high-inner-diameter precision capillary automatic tube drawing device, the chain-type buckle connector includes a connecting chain disposed on the capillary winding cylinder, a capillary buckle block disposed on the connecting chain, and a buckle screw disposed inside the capillary buckle block.

[0016] Compared with existing technologies, the advantages of this invention are:

[0017] 1. In the process of using this invention, the mandrel is placed inside the capillary copper tube, and the capillary copper tube is passed through the capillary copper tube alignment conveyor.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4As shown, an automated capillary tube drawing device with high inner diameter precision includes an operating host 1. The operating host 1 is equipped with a rotatable capillary winding cylinder 2. The capillary winding cylinder 2 is equipped with a chain-type buckle connector 3. The side of the operating host 1 is equipped with a capillary alignment conveyor 4, which corresponds to the position of the capillary winding cylinder 2. The capillary winding cylinder 2 is also equipped with a capillary winding and tidying component 5, which can reciprocate linearly along one end close to or away from the capillary winding cylinder 2. The capillary winding and tidying component 5 is slidably engaged with the capillary winding cylinder 2.

[0027] In this embodiment, during use, the mandrel is placed inside the capillary copper tube, and the capillary copper tube is passed through the capillary copper tube alignment conveyor 4. The capillary copper tube alignment conveyor 4 can ensure the accuracy of capillary copper tube conveying. The head of the capillary copper tube is locked and fixed by the chain-type buckle connector 3 to prevent the capillary copper tube from falling off during the winding process. The fixing effect is good. At this time, the capillary winding cylinder 2 is rotated to wind the capillary copper tube connected to the mandrel. At this time, the capillary winding and sorting component 5 can sort the capillary copper tube located on the capillary winding cylinder 2, so as to avoid the capillary copper tube being messy during the winding. The winding is neat and tidy, without the need for manual adjustment, reducing the labor intensity and achieving a high degree of automation.

[0028] Combination Figure 1-4 As shown, the capillary winding and sorting assembly 5 includes a capillary winding and sorting push cylinder 6 disposed on the capillary winding cylinder 2. The capillary winding and sorting push cylinder 6 is provided with a capillary abutment ring plate 7, which is slidably engaged with the capillary winding cylinder 2.

[0029] Specifically, when winding the capillary copper tube, the capillary winding and tidying pusher 6 is moved closer to the end of the capillary winding cylinder 2. The capillary abutment plate 7 winds and tidies the capillary copper tube located on the capillary winding cylinder 2, avoiding the capillary copper tube from being messy during winding. The winding is neat and tidy, without the need for manual adjustment, reducing the intensity of manual labor and achieving a high degree of automation.

[0030] The capillary winding cylinder 2 is provided with an anti-drop inner ring baffle 13, which is positioned opposite to the capillary abutment ring plate 7.

[0031] In this embodiment, when the capillary copper tube located on the capillary winding cylinder 2 is wound and arranged by the capillary abutment ring plate 7, the anti-fall-off inner ring baffle 13 can prevent the capillary copper tube from falling off from the back of the capillary winding cylinder 2, and the structure is reasonable and compact.

[0032] Combination Figure 2 , Figure 3As shown, the capillary winding and sorting pusher 6 is provided with an anti-deviation connecting sliding member 8, which extends into the capillary winding cylinder 2 and slides in cooperation with the capillary winding cylinder 2.

[0033] In this embodiment, during the movement of the capillary winding and sorting pusher 6, the sliding cooperation between the anti-deviation connecting slider 8 and the capillary winding cylinder 2 can prevent the capillary winding and sorting pusher 6 from shifting at an angle, resulting in a better sorting effect.

[0034] The anti-deviation connecting sliding component 8 includes an anti-deviation connecting sliding rod 9 disposed on the capillary winding and straightening push cylinder 6. The capillary winding cylinder 2 is provided with an anti-deviation connecting hole 10. The anti-deviation connecting sliding rod 9 extends into the anti-deviation connecting hole 10 and slides in cooperation with the anti-deviation connecting hole 10.

[0035] In this embodiment, during the movement of the capillary winding and sorting pusher 6, the sliding cooperation between the anti-deviation connecting sliding rod 9 and the anti-deviation connecting hole 10 can prevent the capillary winding and sorting pusher 6 from shifting at an angle, resulting in a better sorting effect, while not affecting the rotation of the capillary winding cylinder 2.

[0036] Combination Figure 4 As shown, the capillary winding and sorting pusher 6 is provided with a detachable screw-on fixing seat 11 at one end away from the capillary winding cylinder 2. The detachable screw-on fixing seat 11 is provided with a linear driver 12, and the power shaft of the linear driver 12 is connected to the capillary winding and sorting pusher 6.

[0037] In this embodiment, the detachable screw-fixed base 11 is fixed to the operating host 1 by bolts. The detachable screw-fixed base 11 has an open structure and does not affect the winding of the capillary copper tube. When it is necessary to move the capillary tube winding and sorting push cylinder 6, the linear driver 12 can be started. The degree of automation is high. Those skilled in the art should understand that the linear driver 12 can be a cylinder, a hydraulic cylinder or a linear motor.

[0038] The capillary alignment conveyor 4 includes an alignment inlet frame 14 disposed on the side of the operating host 1. The alignment inlet frame 14 is provided with a tube-pulling inlet 15. The alignment inlet frame 14 is provided with a secondary alignment seat 16. The secondary alignment seat 16 is provided with a tube-pulling alignment groove 17. The tube-pulling alignment groove 17 and the tube-pulling inlet 15 are located on the same horizontal plane. The secondary alignment seat 16 is provided with an anti-deviation outer mold 18. The anti-deviation outer mold 18 is positioned corresponding to the tube-pulling alignment groove 17.

[0039] In this embodiment, during use, the mandrel is placed inside the capillary copper tube, the capillary copper tube is passed through the tube inlet 15, and then enters the tube alignment groove 17 in the secondary alignment seat 16. The capillary copper tube is positioned by the anti-deviation outer mold 18, which can ensure the accuracy of the capillary copper tube during delivery.

[0040] Combination Figure 1-2 As shown, the chain-type buckle connector 3 includes a connecting chain 19 disposed on the capillary winding cylinder 2, a capillary buckle block 20 disposed on the connecting chain 19, and a buckle screw 21 disposed inside the capillary buckle block 20.

[0041] In this embodiment, the capillary copper tube head passes through the capillary tube buckle block 20, and the capillary copper tube head is snapped and fixed to the capillary tube buckle block 20 by the buckle screw 21, so as to prevent the capillary copper tube from falling off during the winding process. The fixing effect is good, and the connecting chain 19 does not affect the rotation of the capillary tube winding cylinder 2.

[0042] The working principle of this invention is:

[0043] During use, the mandrel is placed inside the capillary copper tube, which is then passed through the tube inlet 15 and into the tube alignment groove 17 within the secondary alignment seat 16. The capillary copper tube is positioned using the anti-deviation outer mold 18, ensuring the accuracy of the capillary copper tube during transport. The head of the capillary copper tube passes through the capillary tube locking block 20, and the locking screw 21 secures the head of the capillary copper tube to the capillary tube locking block 20, preventing the capillary copper tube from falling off during winding. The fixing effect is good, and the connecting chain 19 is not affected. The capillary winding cylinder 2, driven by a servo motor, rotates to wind the capillary copper tube connected to the mandrel. During this winding process, the capillary winding and tidying pusher 6 moves towards one end of the capillary winding cylinder 2. The capillary abutment plate 7 then tidies up the winding of the capillary copper tube on the cylinder 2, preventing it from becoming haphazard and ensuring a neat winding without manual intervention. This reduces labor intensity and achieves a high degree of automation.

[0044] When the capillary copper tube located on the capillary winding cylinder 2 is wound and arranged through the capillary abutment ring plate 7, the anti-fall-off inner ring baffle 13 can prevent the capillary copper tube from falling off from the back of the capillary winding cylinder 2. The structure is reasonable and compact.

[0045] During the movement of the capillary winding and sorting pusher 6, the sliding engagement between the anti-deviation connecting sliding rod 9 and the anti-deviation connecting hole 10 prevents angular deviation of the capillary winding and sorting pusher 6, resulting in better sorting effect, while not affecting the rotation of the capillary winding cylinder 2.

[0046] The detachable screw-fixed base 11 is fixed to the operating host 1 by bolts. The detachable screw-fixed base 11 has an open structure and does not affect the winding of the capillary copper tube. When it is necessary to move the capillary tube winding and sorting push cylinder 6, the linear drive 12 can be started, which has a high degree of automation.
