Description
Technical Field
[0001] The utility model relates to a cutting device for an oil pipe of a hydraulic station. Background Art
[0002] The hydraulic station is an electromechanical device that provides lubrication and power for the operation of large and medium-sized industrial machinery. It is mainly composed of a hydraulic pump, a drive motor, an oil tank, a directional valve, a throttle valve, a relief valve, etc. At the same time, multiple oil pipes are set between the components to establish connections, so that the oil in the oil tank can circulate between the components along the oil system. In order to ensure the strength and service life of the oil pipe, most of the current oil pipes are made of metal materials. At the same time, the oil pipe needs to be cut into specified lengths according to design requirements, and then bend, flare, and other processes. In order to ensure that the length of the oil pipe has a small error, It is also necessary to straighten the metal oil pipe before cutting. The existing cutting equipment does not have the straightening function. Therefore, if you want to straighten it, you must first complete the straightening of the metal oil pipe in the straightening equipment, and then send it to the cutting equipment for cutting. This requires the straightening and cutting steps to be performed separately, so the processing steps are more cumbersome and consume a lot of time. The connection between the cutting equipment and the straightening equipment is not smooth enough, which makes the processing process easily interrupted, thereby seriously affecting the processing efficiency. In addition, the straightening effect of the straightening equipment is also poor, and the straightening speed is also slow, which needs further improvement. Utility Model Content

[0032] Directions:
[0033] Pass one end of the metal oil pipe 7 to the right through the two second guide sleeves 3111 in a feed unit 31 on the left and pass between the two feed groove wheels 318 in a feed unit 31 on the left, then pass to the right through the guide hole 481 in a left end cover 48 in the straightening mechanism 4, then pass to the right through the through hole 464 and the straightening hole 471 in the straightening block 47 in each straightening module, then pass to the right through the guide hole 481 in a right end cover 48 in the straightening mechanism 4, then pass to the right through the two second guide sleeves 3111 in a feed unit 31 on the right and pass between the two feed groove wheels 318 in a feed unit 31 on the right, then pass to the right between the fixed pressure wheel 62 and the dynamic pressure wheel 65, and finally pass to the right through the first guide sleeve 516.
[0034] The feed motor 32 in the feed mechanism 3 is started to rotate its rotating shaft to drive the third pulley 317 in the two feed units 31 to rotate with the help of the first pulley 33, the second belt 34 and the two steering pulleys 36, thereby driving the feed shaft 316 in the fixed block 3112 in each feed unit 31 to rotate, thereby driving the feed shaft 316 in the movable block 314 to rotate with the help of two gears 315, thereby driving the two feed groove wheels 318 to rotate in opposite directions, thereby driving the metal oil pipe 7 to feed to the right; at the same time, the clamping motor 63 in the clamping mechanism 6 is started to rotate its rotating shaft, thereby clamping the metal oil pipe 7 with the help of the fixed clamping wheel 62 and relying on the mutual clamping cooperation of the movable clamping wheel 65 and driving it to feed to the right.
[0035] When one end of the metal oil pipe 7 is led out to a certain length, the cutting motor 52 in the cutting mechanism 5 is started to rotate its rotating shaft, and then the driving disk 56 is driven to rotate eccentrically in the limit ring 57 with the help of the cutting shaft 55, so that the traction bar 58 is driven to move back and forth between the two limit blocks 515 with the help of the transmission arm. When the knife seat 59 located at the front end of the traction bar 58 moves forward with the traction bar 58, the arc-shaped cutting groove 591 on the knife seat 59 clamps the metal oil pipe 7 forward and cuts it off by shear stress. After cutting, the knife seat 59 will move backward and reset with the traction bar 58, thereby forming a cycle.
[0036] During the feeding process of the metal oil pipe 7, it is also necessary to start the straightening motor 41 in the straightening mechanism 4 to rotate its rotating shaft, and then drive the straightening column 46 to rotate with the help of the second pulley 42, the third pulley 44 and the first belt 43, thereby driving each straightening module to rotate synchronously. During the rotation of each straightening module, the straightening hole 471 in the straightening block 47 will straighten the curved part of the metal oil pipe 7 during the rotation process, thereby ensuring that the metal oil pipe 7 is in a straight state before cutting; the radial position of the straightening block 47 in the rectangular through hole 461 can be adjusted by screwing the studs 48 in each straightening module in coordination with each other, so that the straightening hole 471 in the straightening block 47 is in a concentric position with the through hole 464; the straightening block 47 can be removed by removing any stud 48.
[0037] The utility model integrates the straightening function, so that the straightening and cutting steps of the metal oil pipe 7 can be carried out in the same device, thereby simplifying the processing steps to save a lot of time, and at the same time enabling the straightening step and the cutting step to be smoothly connected and coordinated, thereby ensuring that the processing process can be carried out continuously and uninterruptedly to effectively ensure the processing efficiency; in addition, it also greatly improves the straightening effect and speeds up the straightening speed.
