[0002] In percutaneous hepatic biliary drainage kits, a puncture needle needs to be installed inside the drainage tube during use. The filament-supported P-shaped drainage tube is curved. To prevent the puncture needle from puncturing the drainage tube when it is inserted, a straightening tube is installed on the outside. Pushing the straightening tube forward straightens the drainage tube, allowing the puncture needle to pass through smoothly. To prevent the straightening tube from scratching the drainage tube, its edges are chamfered. This utility model relates to a chamfering machine for both ends of the straightening tube, used in the production process of percutaneous hepatic biliary drainage catheters to chamfer both ends of the straightening tube component.
[0003] In the chamfering process of straight pipes, both ends of each straight pipe need to be chamfered. The traditional processing method is for the operator to hold the straightened pipe by hand, place one end of the straightened pipe against a rotating chamfering knife, and complete the chamfering action of one end. Then, the other end is placed against the chamfering knife to complete the chamfering action of the other end. Holding the straightened pipe by hand for a long time is quite strenuous and has poor stability. Utility Model Content

A horizontal guide groove 17 is fixedly connected to the upper right side of the guide groove support plate 20. A feeding bin 16 is fixedly connected to the upper side of the horizontal guide groove 17. A vertical guide groove 19 is fixedly connected to the lower left side of the horizontal guide groove 17.
[0024] By placing a batch of straightened tube components into the feeding bin 16 and pressing the start button 21, the equipment starts running. The straightened tube components in the feeding bin 16 slide down naturally, with the bottommost one falling into the through groove of the feeding plate body 18. The feeding plate cylinder 12 pushes the feeding plate body 18 to move in the horizontal guide groove 17, which can push the straightened tube components in the through groove of the feeding plate body 18 to the top of the vertical guide groove 19. Then, the straightened tube components fall naturally down the vertical guide groove 19 onto the receiving plate body 9. At this time, the moving clamp cylinder 14 pushes the moving clamp body 7, and the moving clamp body 7 lifts the straightened tube components. The material is pushed onto the stationary clamping block 8 and clamped. During equipment operation, the chamfering motor 3 runs continuously. The chamfering push cylinder pushes the chamfering motor 3 towards the center. The chuck 4 on the chamfering motor 3 drives the chamfering cutter 5 to rotate. Then, the chamfering push cylinder 2 retracts. During the retraction process, when the chamfering cutter 5 passes the brush on the lint collection box 6, the lint on the chamfering cutter 5 is cleaned off. The receiving plate cylinder 15 retracts the receiving plate body 9. Then, the moving clamping block cylinder 14 retracts the moving clamping block body 7. The processed straightened tube material naturally falls into the receiving box 10, which plays the role of completing the chamfering work on both ends of the straightened tube.
[0025] Reference Figure 1 A button box 23 is fixedly connected to the upper right side of the base 1 of the machine. A start button 21 and an emergency stop button 22 are fixedly connected to the upper two sides of the button box 23, respectively. The feeding plate cylinder 12 drives the feeding plate body 18 to move. After the straightening tube part slides naturally from the feeding bin 16 into the groove of the feeding plate body 18, the straightening tube part is transported to the vertical guide groove 19 through the horizontal guide groove 17. The chamfering push cylinder 2 drives the chamfering motor 3 to move horizontally, and the chamfering blade 5 straightens the tube part. After the pipe is chamfered, the chamfering cutter 5 will rotate (controlled by the chamfering motor 3) and pass through the brush on the shavings collection box 6 to sweep away the shavings generated during processing and retain them in the shavings collection box 6. The shavings collection boxes 6 are fixedly connected to both sides of the upper part of the machine base 1, and the receiving box 10 is fixedly connected to the middle side of the upper part of the machine base 1. The feeding plate body 18 is slidably connected to the inside of the horizontal guide groove 17, and the horizontal guide groove 17 is connected to the vertical guide groove 19.
[0026] A button box 23 is fixedly connected to the upper right side of the base 1. A start button 21 and an emergency stop button 22 are fixedly connected to the upper sides of the button box 23, respectively, for controlling the device. The feeding plate cylinder 12 drives the feeding plate body 18 to move. After the straightening tube naturally slides from the discharge bin 16 into the slot of the feeding plate body 18, the straightening tube is transported through the horizontal guide groove 17 to the vertical guide groove 19, facilitating the conveying of the straightening tube. The chamfering propulsion cylinder 2 drives the chamfering motor 3 to move horizontally. After the chamfering blade 5 chamfers the straightening tube, the chamfering blade 5... During the retraction process, the shavings generated during processing are swept away and retained in the shavings collection box 6 by the brush on the shavings collection box 6 while rotating (controlled by the chamfering motor 3), which facilitates the processing of the straightened tube parts. The shavings collection boxes 6 are fixedly connected to both sides of the upper part of the machine base 1, and the receiving box 10 is fixedly connected to the middle side of the upper part of the machine base 1, which serves to collect waste shavings and straightened tube parts respectively. The feeding plate body 18 is slidably connected to the inside of the horizontal guide groove 17, and the horizontal guide groove 17 is connected to the vertical guide groove 19, which facilitates the conveying of the straightened tube parts.
[0027] Working Principle: When using this device, the chamfering operation of both ends of the straight tube is completed by "placing the straightened tube material → pressing the start button 21 → automatic chamfering in sequence → material removal". A batch of straightened tube materials is placed into the feeding bin 16, and the start button 21 is pressed. The equipment starts running, and the straightened tube materials in the feeding bin 16 slide down naturally. The bottommost tube falls into the through groove of the feeding plate body 18. The feeding plate cylinder 12 pushes the feeding plate body 18 to move in the horizontal guide groove 17, pushing the straightened tube material in the through groove of the feeding plate body 18 above the vertical guide groove 19. Then, the straightened tube material falls naturally down the vertical guide groove 19 onto the receiving plate body 9. At this time, the moving clamping block cylinder 14 pushes the moving clamping block body 7, which pushes the straightened tube material onto the stationary clamping block 8 for clamping. During operation, the chamfering motor 3 runs continuously. The chamfering push cylinder pushes the chamfering motor 3 towards the center, and the chuck 4 on the chamfering motor 3 drives the chamfering blade 5 to rotate, completing the chamfering action on both ends of the straightened tube. Afterwards, the chamfering push cylinder 2 retracts. During the retraction process, the chamfering blade 5 passes by the brush on the shavings collection box 6, and the shavings on the chamfering blade 5 are cleaned off. The receiving plate cylinder 15 retracts the receiving plate body 9, and then the moving clamping block cylinder 14 retracts the moving clamping block body 7. The processed straightened tube naturally falls into the receiving box 10, completing one set of actions. The equipment will automatically repeat the above actions to complete the chamfering of each straightened tube. In case of emergency, pressing the emergency stop button 22 enables the chamfering of both ends of the straight tube without manual intervention after startup, greatly saving manpower and improving production efficiency.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
