Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to an automatic chamfering processing device for stainless steel pipes. Background Technology

[0002] Stainless steel pipe is a hollow long steel material made from stainless steel through extrusion, welding or seamless processes. After the pipe is cut, sharp edges or micro-cracks are easily formed at the inner hole edge, which leads to stress concentration. By chamfering, the sharp edges are transformed into rounded corners, reducing the stress peak and preventing the pipe from cracking under pressure or vibration.

[0003] A search revealed Chinese patent CN210789514U, which discloses a special pipe end chamfering device for stainless steel pipes. This device addresses the issue that stainless steel pipes require chamfering at their ends for ease of assembly and improved processing. However, existing chamfering devices are often inconvenient to adjust or fix to the pipe, reducing their practicality and usability. This new device, however, allows for adjustment of the chamfering head and fixation of the pipe, solving the problem of limited practicality in existing stainless steel pipe end chamfering devices. It possesses high practicality and is worthy of widespread adoption.

[0004] When the above-mentioned chamfering device is used, it is convenient to adjust and fix the chamfering device. However, in the existing technology, when stainless steel pipes are being chamfered, operators need to stand by and watch. After the stainless steel pipe is chamfered, it is taken out of the processing table. Frequent manual unloading of stainless steel pipes can easily increase the workload of operators and is not conducive to the continuity of large-scale stainless steel pipe chamfering processing, thus reducing the processing efficiency of stainless steel pipes. Utility Model Content

[0007] The discharge assembly includes a ramp block, which is fixedly connected to one side of the processing table. A mounting frame is fixedly connected to one side of the ramp block, and multiple limiting plates are fixedly connected to the upper surface of the mounting frame. A rubber pad is provided on the upper surface of the ramp block.

[0009] A stepper motor is fixedly installed on one side of the processing table, and a screw is fixedly connected to the output end of the stepper motor. A pusher is connected to the external thread of the screw.

[0010] As a further description of the above technical solution:

[0011] The mounting frame has multiple fixed rods inside, and two sliding sleeves are slidably connected to the outside of the fixed rods.

[0012] As a further description of the above technical solution:

[0013] A return spring is fixedly connected between two of the sliding sleeves. The return spring is sleeved outside the fixed rod. A rotating rod is hinged to the upper surface of the sliding sleeve. A collection frame is hinged to one end of the plurality of rotating rods.

[0014] As a further description of the above technical solution:

[0015] A clamping assembly is provided on one side of the mounting plate. The clamping assembly includes a hydraulic cylinder, which is fixedly mounted on one side of the mounting plate. A connecting frame is fixedly connected to the output end of the hydraulic cylinder.

Two clamping plates are threadedly connected to the external side of the bidirectional stud. The two clamping plates are slidably connected inside the fixed frame.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, through the setting of the discharge component, uses a pusher to easily push the stainless steel tube from the processing table, and guides it through the ramp block to roll it into the collection frame. The rubber pad increases the friction of the stainless steel tube during the guided rolling, thereby reducing the impact force of the stainless steel tube during rolling. At the same time, the collection frame is connected by a rotating rod and a return spring, so that when the collection frame generates elasticity, it can help to buffer the steel tube rolling onto the collection frame, thereby reducing the impact force of the stainless steel tube during discharge. In addition, the limiting plate helps to protect the stainless steel tube, which facilitates the automatic discharge of the stainless steel tube and improves the continuity of the processing.

[0022] 2. This utility model, through the setting of the clamping component, uses the close proximity of the clamping plates to facilitate the clamping and fixing of the stainless steel tube on the processing table, thereby reducing the displacement of the stainless steel tube during chamfering, which could lead to damage and reduced processing quality. Furthermore, through the connection of the hydraulic cylinder and the connecting frame, it is convenient to drive the clamping plate to rise when the stainless steel tube needs to be discharged after chamfering, thus facilitating the discharge of the stainless steel tube.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] As attached Figure 1-6As shown, one embodiment of this utility model is provided: an automatic chamfering processing device for stainless steel pipes, including a processing table 1, an mounting plate 2 fixedly connected to the upper surface of the processing table 1, a variable speed motor 3 fixedly installed on the inner wall of the mounting plate 2, a chamfering head 4 fixedly connected to the output end of the variable speed motor 3, and a discharge assembly provided on one side of the processing table 1.

[0033] The discharge assembly includes a ramp block 5, which is fixedly connected to one side of the processing table 1 to guide the stainless steel tube. A mounting frame 6 is fixedly connected to one side of the ramp block 5, and multiple limiting plates 7 are fixedly connected to the upper surface of the mounting frame 6 to limit the movement of the stainless steel tube. A rubber pad 8 is provided on the upper surface of the ramp block 5 to increase the resistance when the stainless steel tube moves.

[0034] As attached Figure 2 As shown, a stepper motor 9 is fixedly installed on one side of the processing table 1. A screw 10 is fixedly connected to the output end of the stepper motor 9. A pusher 11 is threadedly connected to the outside of the screw 10, which facilitates the movement of the pusher 11. The pusher 11 is slidably connected to the outside of the processing table 1, so that the processing table 1 limits the pusher 11.

[0035] As attached Figure 3 As shown, multiple fixing rods 12 are fixedly connected inside the mounting frame 6. Two sliding sleeves 13 are slidably connected to the outside of the fixing rods 12. The fixing rods 12 guide the sliding sleeves 13. A return spring 14 is fixedly connected between the two sliding sleeves 13. The return spring 14 is sleeved on the outside of the fixing rods 12. The fixing rods 12 limit the return spring 14. The return spring 14 pushes the sliding sleeves 13 back. A rotating rod 15 is hinged to the upper surface of the sliding sleeve 13. One end of the multiple rotating rods 15 is hinged to a collection frame 16, which makes the collection frame 16 generate elastic force, thereby generating a buffer force.

[0036] As attached Figure 1 As shown, a clamping assembly is provided on one side of the mounting plate 2. The clamping assembly includes a hydraulic cylinder 17, which is fixedly installed on one side of the mounting plate 2. A connecting frame 18 is fixedly connected to the output end of the hydraulic cylinder 17 for mounting and connecting a fixed frame 19. Two fixed sleeves 23 are fixedly connected to one side of the mounting plate 2. The connecting frame 18 is slidably connected to the outside of the fixed sleeves 23, which limits the movement of the connecting frame 18. A fixed frame 19 is fixedly connected to one end of the connecting frame 18. A stepper motor 20 is fixedly installed on one side of the fixed frame 19. A bidirectional stud 21 is fixedly connected to the output end of the stepper motor 20. The external threads of the bidirectional stud 21 are set in opposite directions. Two clamping plates 22 are connected to the external threads of the bidirectional stud 21 to facilitate clamping and fixing the steel pipe. The two clamping plates 22 are slidably connected inside the fixed frame 19, and the fixed frame 19 limits the movement of the clamping plates 22.

[0037] Working principle: In use, the stainless steel pipe is first placed on the surface of the processing table 1, and then the pipe end is inserted into the outside of the chamfering head 4. The stepper motor 20 is started by the controller, so that the output end of the stepper motor 20 drives the bidirectional stud 21 to rotate. Under the action of the opposite direction threads on the outside of the bidirectional stud 21, it is easy to drive the two clamping plates 22 to move closer to each other, so as to facilitate the clamping and fixing of the stainless steel pipe. Then the variable speed motor 3 is started, and its output end drives the chamfering head 4 to rotate, thereby chamfering the inner wall of the stainless steel pipe end. After the chamfering is completed, the reverse function of the stepper motor 20 is started, and the two clamping plates 22 are driven to move away from the stainless steel pipe. Then the hydraulic cylinder 17 is started, and its output end drives the connecting frame 18 to rise, so that the connecting frame 18 indirectly drives the two clamping plates 22 to rise, thereby facilitating the passage of the stainless steel pipe.

[0038] During discharge, the stepper motor 9 is started, and its output end drives the screw 10 to rotate. When the screw 10 drives the pusher 11 to slide on the surface of the processing table 1, it pushes the stainless steel tube, causing the stainless steel tube to roll. Guided by the ramp block 5, the stainless steel tube passes through the rubber pad 8. The rubber pad 8 increases the resistance of the stainless steel tube, reducing the rolling speed of the stainless steel tube, so that the stainless steel tube rolls to the collection frame 16. When the stainless steel tube rolls to the collection frame 16 and exerts an impact force on the collection frame 16, causing it to press down, the collection frame 16 will drive multiple rotating rods 15 to rotate. The rotating rods 15 push the sliding sleeve 13 to slide outside the fixed rod 12. When the sliding sleeves 13 on both sides approach each other, they will squeeze the return spring 14. The return spring 14 is compressed and deformed, generating a rebound force, which pushes the sliding sleeves 13 on both sides, causing the sliding sleeves 13 to return to their original position and slide. This buffers the impact force of the collection frame 16 on the stainless steel tube, helping to reduce the impact force when the stainless steel tube is discharged.

[0039] 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.
