[0046] Reference Figures 1-5 The utility model provides a pipe end chamfer processing device, including the feeding slide 110 of unloading, set up on the support 100, the feeding slide 110 is used for pipe falling, the pipe in the feeding slide 110 is arranged in height direction in proper order;Fixed part 120 sets up on the support 100;First sliding part 210 is slidably arranged on the support 100, first sliding part 210 is close to or away from fixed part 120 after sliding, first sliding part 210 is close to fixed part 120 after, first sliding part 210 and fixed part 120 between the first clamping space 211 that constitutes, first clamping space 211 is used for clamping pipe, first sliding part 210 is away from fixed part 120 after, first sliding part 210 is located below the feeding slide 110 of unloading, and first sliding part 210 is used for the pipe that the feeding slide 110 of unloading slides down receives;Chamfer device 220 is slidably arranged on both sides of first clamping space 211, chamfer device 220 is close to or away from the both ends of pipe in first clamping space 211 after sliding.

[0047] In actual operation, the support 100 supports the entire device. The feeding chute 110 is mounted on the support 100, and the pipe to be processed is arranged in the feeding chute 110 in the height direction, and falls downward by gravity. When the first sliding member 210 is located away from the fixed member 120, the first sliding member 210 can receive a pipe falling from the feeding chute 110, and then push the pipe to be close to the fixed member 120. The space between the first sliding member 210 and the feeding chute 110 can only accommodate one pipe, and the remaining pipes are blocked in the feeding chute 110 and cannot fall down. When the first sliding member 210 slides away from below the feeding chute 110, the first sliding member 210 always has a part staying below the feeding chute 110, continuously blocking the pipe on the feeding chute 110 from falling down, until the part of the first sliding member 210 for receiving the pipe is located below the feeding chute 110 again, so as to realize the feeding of the pipes one by one. The fixed member 120 is fixed on the support 100 and does not move, and can play a positioning role. When the first sliding member 210 slides to be close to the fixed member 120, a first clamping space 211 is formed between the first sliding member 210 and the fixed member 120, for clamping the pipe. The chamfering device 220 can slide on both sides of the first clamping space 211. When chamfering is needed for the end of the pipe, the chamfering device 220 slides to be close to both ends of the pipe in the first clamping space 211. After chamfering is completed, the chamfering device 220 slides away from the pipe.

[0048] Firstly, the feeding chute 110 realizes automatic feeding of the pipe, improves the feeding efficiency, and reduces manual operation. Secondly, the sliding design of the first sliding member 210 can receive the pipe and clamp the pipe together with the fixed member 120, which ensures the stability of the pipe during processing. Furthermore, the sliding design of the chamfering device 220 facilitates chamfering operation on both ends of the pipe, improving the flexibility and efficiency of processing.

[0049] Further, the second sliding member 230 is slidably arranged on the support 100, and the second sliding member 230 slides to be close to or away from the first sliding member 210. The second sliding member 230 is located on the side of the first sliding member 210 close to the fixed member 120. After the second sliding member 230 is close to the first sliding member 210, the first sliding member 210 and the second sliding member 230 form a second clamping space 231. The discharge chute 300 is arranged on the support 100, and the discharge chute 300 is located between the feeding chute 110 and the fixed member 120. After the first sliding member 210 and the second sliding member 230 move away from each other, the pipe in the second clamping space 231 falls into the discharge chute 300.

[0050] In the actual operation, the second sliding member 230 can also slide on the support 100. When the second sliding member 230 slides close to the first sliding member 210, the second clamping space 231 is formed together with the first sliding member 210. After the pipe on the feeding lower chute 110 falls on the first sliding member 210, the second sliding member 230 slides close to the first sliding member 210 and forms the second clamping space 231 together with the first sliding member 210. The first sliding member 210 and the second sliding member 230 jointly clamp the pipe, and then the first sliding member 210 and the second sliding member 230 slide synchronously to make the pipe close to the fixed member 120, which can prevent the pipe from falling during the sliding of the first sliding member 210, thereby improving the stability of the pipe conveying. After the first sliding member 210 and the second sliding member 230 clamp the pipe and abut against the fixed member 120, the first sliding member 210 and the second sliding member 230 stop sliding. In this way, a pressure sensor can be added on the fixed member 120.

[0051] After the chamfering of the pipe in the first clamping space 211 is completed by the chamfering device 220, the first sliding member 210 slides away from the fixed member 120, and the second sliding member 230 remains stationary. After the first sliding member 210 moves away by a certain distance, the second sliding member 230 slides close to the first sliding member 210 to push the pipe to slide and fall to the discharging lower chute 300, thereby providing space for the next pipe to be chamfered.

[0052] It should be further explained that the first sliding member 210 cannot independently support the pipe falling from the feeding lower chute 110. The first sliding member 210 needs to jointly receive the pipe with the second sliding member 230, and then clamp the pipe. After the first sliding member 210 and the second sliding member 230 move away, the pipe can fall into the discharging lower chute 300 under the action of gravity.

[0053] Further, the first sliding member 210 has an abutting portion 212 and a blocking portion 213. The abutting portion 212 is arc-shaped and is used to receive the pipe falling from the feeding lower chute 110 and clamp the pipe with the fixed member 120 or the second sliding member 230. After the abutting portion 212 slides close to the fixed member 120, the blocking portion 213 is located at the bottom of the feeding lower chute 110 and is used to block the pipe in the feeding lower chute 110 from falling.

[0054] In this embodiment, the abutting portion 212 of the first sliding member 210 is arc-shaped. When the pipe material falls from the feeding downward chute 110, it will first fall on the arc-shaped abutting portion 212. The arc-shaped abutting portion 212 cannot support the pipe material alone. After the second sliding member 230 and the first sliding member 210 move away from each other, the pipe material can fall under the action of gravity. When the abutting portion 212 slides close to the fixed member 120, the blocking portion 213 will move to the bottom position of the feeding downward chute 110, thereby blocking the subsequent pipe material in the feeding downward chute 110 from falling down, and playing a role in controlling the unloading rhythm of the pipe material.

[0055] Firstly, the arc-shaped abutting portion 212 can better adapt to the shape of the pipe material, improving the stability of receiving and clamping. Secondly, the setting of the blocking portion 213 effectively avoids the interference of excess pipe material during processing, ensuring that only one pipe material is processed at a time, improving the accuracy and efficiency of processing. Furthermore, it is convenient for the first sliding member 210 and the second sliding member 230 to move away from each other, so that the pipe material can freely fall.

[0056] Further, the inclined chute 112 is arranged on the support 100, the feeding downward chute 110 is located below the low end of the inclined chute 112, and the inclined chute 112 is used for conveying the pipe material to the feeding downward chute 110; the first baffle 113 has two, which are arranged on both sides of the inclined chute 112 respectively, and the two first baffles 113 form a conveying space 114, which is used for the pipe material to pass through.

[0057] In this embodiment, the inclined chute 112 is installed on the support 100, and the position thereof is higher than that of the feeding downward chute 110. The pipe material is placed on the inclined chute 112. Due to the inclined design, the pipe material will slide to the low end under the action of gravity, and then fall into the feeding downward chute 110 located below.

[0058] The first baffle 113 is arranged on both sides of the inclined chute 112 respectively, and the two first baffles 113 jointly form a conveying space 114. The size of the conveying space 114 is just enough to allow the pipe material to pass through, thereby playing a certain guiding and limiting role in the sliding of the pipe material on the inclined chute 112, preventing the pipe material from falling from both sides of the inclined chute 112.

[0059] Further, the belt conveyor 310 is located below the support 100, and the belt conveyor 310 is used for receiving the pipe material falling from the unloading downward chute 300; the second baffle 320 has a plurality of baffles, which are distributed in the conveying direction of the belt conveyor 310 in sequence and at intervals, and each two adjacent second baffles 320 form a containing space 321, which is used for receiving the pipe material falling from the unloading downward chute 300.

[0060] In this embodiment, the belt conveyor 310 is arranged at a lower position of the support 100. When the pipe material falls from the pipe material falling down chute 300, it will fall onto the belt conveyor 310. The belt conveyor 310 is sequentially and spacedly provided with a plurality of second baffles 320 in the conveying direction. Each two adjacent second baffles 320 form a holding space 321. When the pipe material falls from the pipe material falling down chute 300, it will fall into the corresponding holding space 321 and be conveyed by the belt conveyor 310.

[0061] Firstly, the belt conveyor 310 can timely and orderly receive the pipe material falling from the pipe material falling down chute 300 and convey it, thereby improving the efficiency and continuity of the pipe material falling. Secondly, the holding space 321 formed by the second baffles 320 can position and separate the pipe material, thereby avoiding the pipe material from colliding and being disordered in the conveying process and ensuring the orderly arrangement and stability of the pipe material conveying.

[0062] Further, the fixing member 120 is semicircular at one end close to the first sliding member 210, and the fixing member 120 is detachably arranged on the support 100.

[0063] In this embodiment, the fixing member 120 is semicircular at one end close to the first sliding member 210. This shape can better match the shape of the pipe material, thereby improving the stability and adhesion during clamping. The fixing member 120 is detachably mounted on the support 100. This means that when the fixing member 120 is worn, damaged or needs to be replaced with different specifications to adapt to different pipe materials, it can be conveniently detached and replaced.

[0064] Firstly, the semicircular end design enhances the clamping effect and positioning accuracy of the pipe material, ensures that the pipe material will not displace during the chamfering process, and improves the machining precision. Secondly, the detachable mounting mode increases the flexibility and maintainability of the device, reduces the use cost and maintenance difficulty of the equipment. Furthermore, it is convenient to quickly replace the fixing member 120 according to different processing requirements, thereby improving the universality and adaptability of the equipment and meeting more diversified production requirements.

[0065] Further, the chamfering device 220 includes a fixed top member 221 arranged on the support 100, the fixed top member 221 being conical; a sliding top member 222 slidingly arranged on the fixed top member 221, the sliding top member 222 being conical, the sliding top member 222 sliding to be close to or away from the fixed top member 221, the fixed top member 221 and the sliding top member 222 being respectively located at two ends of the first clamping space 211, and a sliding direction of the sliding top member 222 being parallel to an axis of the pipe material; two chamfering knives 223 are respectively rotationally arranged relative to the fixed top member 221 and the sliding top member 222, and the chamfering knives 223 are used for chamfering the end of the pipe material.

[0066] In this embodiment, the fixed top piece 221 is installed on the support 100 and is conical in shape. The sliding top piece 222 is slidably arranged on the fixed top piece 221 and is also conical. The chamfering tool 223 is rotatably arranged on the fixed top piece 221 and the sliding top piece 222. When the pipe is clamped in the first clamping space 211, the sliding top piece 222 slides close to the fixed top piece 221 to complete the positioning of the axial direction of the pipe, and the chamfering tool 223 contacts the end of the pipe and rotates to chamfer the end of the pipe.

[0067] Firstly, the conical fixed top piece 221 and the sliding top piece 222 can adapt to pipes of different diameters, improving the versatility of the device. Secondly, the sliding design of the sliding top piece 222 can flexibly adjust the distance from the fixed top piece 221, ensuring effective chamfering of pipes of different lengths. Thirdly, the rotating chamfering tool 223 can more efficiently and uniformly chamfer, improving processing quality and efficiency.

[0068] It should be further noted that when the sliding top piece 222 moves away from the pipe, the second sliding piece 230 pushes the pipe to slide away from the fixed top piece 221 under the action of the conical fixed top piece 221, thereby separating from the fixed top piece 221.

[0069] Further, the first telescopic piece 224 is arranged on the support 100, and the chamfering tool 223 is rotatably arranged on the telescopic end of the first telescopic piece 224. The first elastic piece 225 is arranged at both ends of the telescopic end of the first telescopic piece 224 and the sliding top piece 222, respectively. The first telescopic piece 224 drives the sliding top piece 222 to slide through the first elastic piece 225, and the first elastic piece 225 provides the force for the sliding top piece 222 to move close to the fixed top piece 221.

[0070] In this embodiment, when the first telescopic piece 224 is telescoped, the force is transmitted to the sliding top piece 222 through the first elastic piece 225 to drive the sliding top piece 222 to slide. When the sliding top piece 222 abuts one end of the pipe, the first telescopic piece 224 continues to expand to continue pushing the pipe to slide towards the fixed top piece 221 through the sliding top piece 222 until the other end of the pipe abuts the fixed top piece 221. The first telescopic piece 224 continues to expand, and the first elastic piece 225 is compressed, so that the telescopic end of the first telescopic piece 224 can be closer to the end of the pipe, thereby making the chamfering tool 223 close to the workpiece to complete chamfering. The purpose of first positioning and clamping and then chamfering is achieved. A driving device can be added between the first telescopic piece 224 and the chamfering tool 223, so that the driving device drives the chamfering tool 223 to be rotatably arranged on the first telescopic piece 224, and the rotation axis of the chamfering tool 223 is collinear with the axis of the pipe.

[0071] Further, the first top block 226 is arranged at the telescopic end of the first telescopic member 224, and the first top block 226 abuts against the sliding top member 222 after the first elastic member 225 is compressed.

[0072] In the embodiment, the first top block 226 abuts against the sliding top member 222 when the first elastic member 225 is compressed, and the abutment can make the sliding top member 222 more stable, so that the chamfering cutter 223 can complete the chamfering of the pipe. After the first top block 226 abuts against the sliding top member 222, the chamfering cutter 223 completes the processing of the pipe, and the processing process becomes more controllable.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
