Description

Technical Field

[0001] This application relates to the field of pipe cutting technology, and more particularly to a fully automatic pipe cutting device. Background Technology

[0002] Automatic pipe cutting machines are high-precision automated equipment used for cutting metal pipes. They are mainly used in mass production scenarios in industries such as petroleum, metallurgy, and automobile manufacturing, supporting fixed-length cutting of metal and some non-metal pipes. However, existing fully automatic pipe cutting equipment generally has low dimensional accuracy of the workpiece after cutting, requiring subsequent equipment to ensure the accuracy of the parts, resulting in longer production lines and relatively low material yield, which reduces the processing effect of the equipment. Furthermore, the equipment is exposed without protection, the working environment is poor, which reduces the aesthetics of the equipment. Moreover, the cutting tools are manually sharpened, which requires high technical skills from the workers. One worker can only manage a maximum of three machines, and the aging workforce is serious, with young people unwilling to do this job. Utility Model Content

The cutting tool holder 21 is installed at the top of the first saddle 2. When the outer circle is finished, the first saddle X-axis servo motor 3 and the first saddle Z-axis servo motor 4 on the first saddle 2 are started to rotate. The first saddle 2 is driven to move in the X-axis and Z-axis directions through the lead screw, so that the steel pipe material can be cut by the cutting tool holder 21.

A tail material receiving mechanism 17 is installed on the inner wall of the second saddle 15 located below the material receiving mechanism 16. When the second saddle X-axis servo motor 14 and the second saddle Z-axis servo motor 27 on the second saddle 15 are started, the second saddle 15 is driven to move in the X-axis and Z-axis directions through the lead screw, which facilitates the outer diameter machining tool holder 26 to perform chamfering and outer diameter machining on the steel pipe material. The receiving mechanism 16 includes a receiving mechanism mounting bracket 161, a receiving hopper 162, a baffle plate 163, a receiving needle 164, a receiving cylinder connecting plate 165, a guide rod 166, a cylinder mounting bracket 167, a receiving cylinder 168, and a guide sleeve 169. The receiving mechanism mounting bracket 161 is mounted on one side of the second saddle 15. The receiving hopper 162 is mounted on one side of the receiving mechanism mounting bracket 161. A cylinder mounting bracket 167 is fixed to the outer wall of the top of the receiving hopper 162. A baffle plate 163 is symmetrically fixed to one side of the cylinder mounting bracket 167 corresponding to the position of the receiving hopper 162. A receiving cylinder 168 is mounted on the cylinder mounting bracket 167. One end of the telescopic rod of the receiving cylinder 168 is fixed to the receiving cylinder connecting plate 165. One side of the receiving cylinder connecting plate 165... A receiving needle 164 is fixedly connected to the receiving cylinder connecting plate 165, and a guide rod 166 is fixedly connected to the other side. A guide sleeve 169 is fixedly connected to the cylinder mounting bracket 167 at the position corresponding to the guide rod 166. When the workpiece is about to be cut off, the receiving mechanism 16 starts to work. First, the receiving cylinder 168 is started to drive the receiving needle 164 on the receiving cylinder connecting plate 165 to move forward. The receiving needle 164 passes through the hole in the steel pipe material. When the receiving needle 164 catches the cut workpiece, the receiving cylinder 168 is started to retract, driving the workpiece to retract. When it moves to the position of the baffle plate 163, it is blocked by the baffle plate 163 and then falls onto the receiving hopper 162. Since the receiving hopper 162 is set with a certain slope, it is convenient to slide the workpiece directly into the subsequent receiving frame after it falls. The tail material receiving mechanism 17 includes a guide rail mounting bracket 171, a tail material receiving mounting bracket 172, a guide rail 173, a tail material hopper connecting plate 174, a tail material cylinder 175, and a tail material hopper 176. A guide rail mounting bracket 171 is installed at one bottom side of the second saddle 15. The tail material receiving mounting bracket 172 is fixedly connected to the top of the guide rail mounting bracket 171. A guide rail 173 is slidably connected to the inner wall of the top of the guide rail mounting bracket 171. The tail material hopper connecting plate 174 is fixedly connected to the bottom of the guide rail 173. A tail material hopper 176 is fixedly connected to one side of the tail material hopper connecting plate 174. A tail material cylinder 175 is installed on one side of the guide rail mounting bracket 171, and the tail material... One end of the telescopic rod of cylinder 175 is fixed to the outer wall of tail hopper 176. Tail box 18 is installed on the inner wall of the fully protective housing 1 below tail hopper 176. When the last part of the steel pipe material cannot be processed, the remaining part of the material is pushed out of front chuck 13 by the steel pipe material pusher. Before the front chuck 13 is pushed out, tail material receiving mechanism 17 starts to work, starts tail cylinder 175 to push forward, drives tail hopper 176 to a suitable position, and the remaining part of steel pipe is withdrawn and falls into tail hopper 176. Since tail hopper 176 is set with an inclination, it is convenient to slide the remaining part of steel pipe into the interior of tail box 18 through the inclination. A hydraulic station 19 is installed on one inner wall of the fully protective housing 1. The hydraulic station 19 can be used to perform hydraulic processing on the equipment to ensure that the equipment can operate normally. A chip conveyor 20 is installed on one side of the fully protective housing 1, and one side of the chip conveyor 20 extends to the outside of the fully protective housing 1. The chip conveyor 20 can collect the generated chips, and then the chips are cleaned up uniformly after the processing is completed.

[0028] The main structural components of this application are as follows: A feeding saddle 25 is installed on the side of the fully protective housing 1. A feeding rear spindle 9 is installed on the top of the feeding saddle 25. A feeding shaft servo motor 8 is installed on one side of the feeding saddle 25. The output shaft of the feeding shaft servo motor 8 is fixedly connected to the outer wall of the feeding rear spindle 9 to drive its rotation. A feeding rear spindle clamping cylinder 22 is installed on the upper end of the feeding rear spindle 9. A rear chuck 10 is connected to its front end for clamping and feeding the steel pipe. A front spindle 12 is also installed on the feeding saddle 25. The front spindle 12 is located in front of the rear chuck 10. A front spindle clamping cylinder 24 is rotatably connected to the outer wall of the front spindle 12. One end of the telescopic rod of the cylinder 24 is connected to the front spindle 12 to realize the clamping action. A front chuck 13 is provided at the front end of the front spindle 12 for clamping the workpiece during processing. A main motor 5 is also installed on the feed saddle 25. A main motor pulley 6 is fixed to the output shaft of the main motor 5. The main motor pulley 6 is connected to the main spindle pulley 11 inside the front spindle 12 through the spindle belt 7 to realize spindle drive. A material head and tail sensor 23 is provided on the side of the feed saddle 25 for detecting the processing position and remaining length of the steel pipe.

[0029] The first saddle cutting mechanism of this application includes a first saddle 2, with a first saddle X-axis servo motor 3 and a first saddle Z-axis servo motor 4 respectively mounted on both sides of the first saddle 2, and a cutting tool holder 21 provided at the top of the first saddle 2. After machining the outer diameter, the first saddle X-axis servo motor 3 and Z-axis servo motor 4 are started to drive the lead screw to move, causing the first saddle 2 to move along the X-axis and Z-axis directions, thereby driving the cutting tool holder 21 to precisely cut the steel pipe.

[0030] The second saddle 15 of this application is equipped with a second saddle X-axis servo motor 14 on one side and a second saddle Z-axis servo motor 27 on the other side. An outer diameter machining tool holder 26 is installed at the top of the second saddle 15 for chamfering and outer diameter machining of steel pipes. The second saddle 15 can move along the X-axis and Z-axis directions through the drive of two sets of servo motors to achieve high-precision outer diameter machining operations. In order to realize automatic pick-up after workpiece cutting, a pick-up mechanism 16 is installed on one side of the second saddle 15, and a tail material receiving mechanism 17 is installed below it.

[0031] The receiving mechanism mounting bracket 161 of this application is fixed to one side of the second saddle 15. A receiving hopper 162 is provided on the bracket. A cylinder mounting bracket 167 is installed above the receiving hopper 162. A baffle plate 163 is provided at the corresponding position of the cylinder mounting bracket 167 to block the workpiece being received. A receiving cylinder 168 is installed on the cylinder mounting bracket 167. The telescopic rod of the cylinder 168 is connected to the receiving cylinder connecting plate 165. A receiving needle 164 is fixed on one side of the connecting plate 165, and a guide rod 166 is provided on the other side. The guide rod 166 is slidably engaged with the guide sleeve 169 to maintain stable movement. When the workpiece is about to be cut, the receiving mechanism 16 automatically starts: The receiving cylinder 168 pushes the receiving needle 164 forward to extend through the inner hole of the steel pipe to receive the cut workpiece. After the workpiece is caught, the receiving cylinder 168 retracts, causing the workpiece to move backward. After being blocked by the baffle plate 163, the workpiece falls into the receiving hopper 162. Because the receiving hopper 162 is set with a certain slope, the workpiece can slide smoothly into the subsequent receiving frame, realizing automatic collection.

[0032] The structure and working process of the tail material receiving mechanism of this application are as follows: The tail material receiving mechanism 17 includes a guide rail mounting bracket 171, a tail material receiving mounting bracket 172, a guide rail 173, a tail material hopper connecting plate 174, a tail material cylinder 175, and a tail material hopper 176. The guide rail mounting bracket 171 is fixed to the bottom of the second saddle 15, and the guide rail 173 is slidably mounted on it. The bottom end of the guide rail 173 is connected to the tail material hopper connecting plate 174, and the connecting plate 174 fixes the tail material hopper 176. The tail material cylinder 175 is installed on one side of the guide rail mounting bracket 171, and the telescopic rod of the cylinder 175 is fixed to the outer wall of the tail material hopper 176. When the remaining portion of the steel pipe can no longer be processed, the subsequent steel pipe will push the tail material away from the front chuck 13. Before this, the tail material receiving mechanism 17 is activated, and the tail material cylinder 175 pushes forward, moving the tail material hopper 176 to the designated position. The tail material is pushed out and falls into the tail material hopper 176. The tail material hopper 176 is inclined to facilitate the tail material sliding into the tail material box 18 below the fully protective housing 1, achieving automatic collection and separation.

[0033] The auxiliary mechanism of this application includes a hydraulic station 19 installed on the inner wall of one side of the fully protective housing 1, which provides hydraulic power to each clamping cylinder to ensure stable and reliable operation of the equipment. A chip conveyor 20 is provided on one side of the housing 1, which extends to the outside of the housing and is used to automatically collect and discharge the waste chips generated during the processing, keep the equipment clean and improve processing efficiency.

[0034] The workflow of this application is as follows: 1. The feeding shaft servo motor 8 drives the feeding spindle 9 to drive the steel pipe forward; 2. The front and rear chucks (10, 13) clamp the workpiece, and the main motor 5 starts to drive the spindle to rotate; 3. The second saddle 15 drives the outer diameter machining tool post 26 to chamfer and finish the outer diameter of the workpiece; 4. After processing is completed, the first saddle 2 drives the cutting tool holder 21 to cut off the workpiece; 5. The receiving mechanism 16 starts automatically to pick up the cut workpiece and slide it into the receiving hopper 162; When tail material is generated, the tail material receiving mechanism 17 automatically feeds the tail material into the tail material box 18; 6. After processing is completed, the chip conveyor 20 cleans up the cutting chips.

[0035] Through the above structure and process, the integrated functions of fully automated pipe cutting, outer diameter machining, automatic workpiece and tail material receiving and chip removal are realized, which significantly improves production efficiency and processing safety.

[0036] The implementation principle of a fully automatic pipe cutting device according to an embodiment of this application is as follows: Steel pipe material is fed to the position sensed by the head and tail sensor 23 via a feeding rack. At this time, the head and tail sensor 23 is activated to detect the position of the steel pipe. When the steel pipe is fed beyond the rear chuck 10 by a certain distance, the feeding rear shaft clamping cylinder 22 pushes the rear chuck 10 to clamp it. Then, the feeding shaft servo motor 8 starts feeding, driving the lead screw to move the feeding bed saddle 25 forward. When the steel pipe material exceeds the front chuck 13 by a certain distance, the front main shaft clamping cylinder 24 pushes the front chuck 13 to clamp it. At this time, the main motor 5 is activated, causing the main motor pulley 6 to rotate. This, through the main shaft belt 7, drives the main shaft pulley 11 on the front main shaft 12 to rotate. Both the chuck 13 and the rear chuck 10 clamp the steel pipe material, so the spindle 9 also rotates after feeding. At this time, the second saddle X-axis servo motor 14 and the second saddle Z-axis servo motor 27 on the second saddle 15 are started, driving the second saddle 15 to move in the X and Z directions via the lead screw. This drives the outer diameter machining tool holder 26 to perform chamfering and outer diameter machining on the steel pipe material. When the outer diameter machining is completed, the first saddle X-axis servo motor 3 and the first saddle Z-axis servo motor 4 on the first saddle 2 are started to rotate, driving the first saddle 2 to move in the X and Z directions via the lead screw. This cuts the steel pipe material through the cutting machining tool holder 21. When the workpiece is about to be cut off, the receiving mechanism 16 starts to work. First, the receiving cylinder 168 is started, driving the receiving cylinder... The receiving pin 164 on the connecting plate 165 moves forward, passing through the hole in the steel pipe material. When the receiving pin 164 catches the cut workpiece, the receiving cylinder 168 is activated to retract, causing the workpiece to move backward. When it moves to the position of the baffle plate 163, it is blocked by the baffle plate 163 and then falls onto the receiving hopper 162. Because the receiving hopper 162 is set with a certain inclination, the workpiece slides directly into the subsequent receiving frame after falling. At the same time, the number of workpieces that can be cut per feeding cycle can be set on the equipment. When one cycle is completed, the next cycle begins. When the last part of the steel pipe material cannot be processed, the remaining material is pushed out of the front chuck 13 by the subsequent steel pipe material pusher. Before being pushed out of the front chuck 13, the tail material receiving mechanism 1... 7. To begin operation, the tailing cylinder 175 is activated to push forward, moving the tailing hopper 176 to the appropriate position. The remaining steel pipe is ejected and falls into the tailing hopper 176. Due to the inclined design of the tailing hopper 176, the remaining steel pipe slides into the tailing box 18, improving the equipment's precision and workpiece accuracy. Simultaneously, it processes outer diameters and chamfers, reducing the need for subsequent equipment. Furthermore, it uses forming tools to cut parts, resulting in a narrower tool width, increasing material yield, improving tool change speed, and reducing labor intensity. The equipment also features a fully protective design, trapping iron filings and rust inside the protective enclosure, improving aesthetics. Simultaneously, it employs a fully automatic PLC control system, automatically handling the head and tail of the material and loading, significantly reducing the labor intensity of workers.One worker can manage 8-10 machines.
