Description
Technical Field
[0001] The utility model relates to the technical field of bending machines, in particular to a numerical control hydraulic bending machine. Background Technique
[0002] A pipe bender is a machine used for bending pipes and can also be used as a jack. It is roughly divided into a numerical control pipe bender, a hydraulic pipe bender, etc., and is applied to pipeline laying and repair in aspects such as electric power construction, highway and railway construction, bridges, and ships. A pipe bender belongs to a type of bending machine.
[0003] During the processing of metal pipes, it is necessary to bend the pipes according to the requirements of the processing shape. Most of the existing pipe benders perform bending by twisting a disc during use. This kind of bending machine is not convenient for synchronously bending the two ends of the pipe, and the use effect is poor; and when the existing bending machine processes the pipe, it is not convenient to adjust the position according to the different bending positions of the pipe, and at the same time, the bending angle is not convenient to control, and the practicability is poor. Content of the Utility Model
[0004] The purpose of the utility model is to provide a numerical control hydraulic bending machine, which has the advantages of double-head synchronous bending, high efficiency, strong operability, and being convenient to adjust the bending position and angle according to the processing requirements, and solves the problems in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A numerical control hydraulic bending machine, including a steel pipe, a bracket, a bottom box, and a rear plate. Both ends inside the bottom box are slidably installed with sliding sleeves. A driving box is fixed in the middle inside the bottom box. A slide rail is provided in the middle of the upper end surface of the bottom box, and a hydraulic rod is slidably installed on the slide rail. The lower end of the hydraulic rod passes through the through groove of the slide rail and is fixed on the corresponding sliding sleeve. The top of the hydraulic rod is fixed on the bracket, and a load-bearing wheel is rotatably installed on the upper side of the bracket through a rotating shaft. Both ends of the steel pipe are respectively located above the two load-bearing wheels. The rear plate is fixed on the rear side of the upper end surface of the bottom box. An internal groove is opened at the top inside the rear plate, and both ends inside the internal groove are slidably installed with internal sleeves. An adjusting rod is fixed at the front end of the internal sleeve. A side groove is opened at the upper side of the front end surface of the rear plate. The front end of the adjusting rod is rotatably installed with a pressing wheel, and the pressing wheel is located outside the side groove.
[0006] When using the numerically controlled hydraulic bending machine in this technical solution, place the two ends of the steel pipe on the upper sides of two load-bearing wheels respectively. Start the motor in the built-in groove to drive the second threaded rod to rotate. The second threaded rod drives the displacement of the built-in sleeve through threading. The built-in sleeve drives two pressing wheels to adjust the distance through the adjusting rod, realizing the change of the processing position. Then start the motor in the drive box to drive the first threaded rod to rotate. The first threaded rod drives the sliding sleeve through threading to drive the bracket on the hydraulic rod to displace. The bracket drives the load-bearing wheel to displace so that its position matches that of the pressing wheel. Then start the hydraulic rod to drive the load-bearing wheel to rise. The load-bearing wheel drives the steel pipe to rise. When the upper side of the steel pipe is clamped inside the pressing wheel, the middle part of the steel pipe remains unchanged. The two ends of the steel pipe are deformed due to the extrusion of the load-bearing wheel and the limit of the pressing wheel. The bending angle is controlled according to the rising height of the hydraulic rod.
[0007] Preferably, foot pads are fixed on the outer side of the lower end surface of the bottom box. There are four foot pads in total, and the four foot pads are arranged in an array. Anti-slip pads are fixed at the lower ends of the foot pads. The bottom box is placed and supported through the foot pads, and the anti-slip pads increase the friction force to ensure the stability of the support.
[0008] Preferably, first threaded rods are rotatably installed between the two ends of the drive box and the inside of the bottom box, and the first threaded rods respectively penetrate through the corresponding sliding sleeves through threading. The motor in the drive box drives the first threaded rod to rotate, and the first threaded rod drives the sliding sleeve to displace through threading.
[0009] Preferably, second threaded rods are rotatably installed at the front and rear ends inside the built-in groove. Positive threads and reverse threads are respectively opened at both ends of the second threaded rod, and the positive and reverse threads respectively penetrate through the corresponding built-in sleeves through threading. The motor in the built-in groove drives the second threaded rod to rotate, and the positive and reverse threads on the second threaded rod drive the relative displacement of the two built-in sleeves.
[0010] Preferably, the front end of the adjusting rod passes through the side groove and is connected to the pressing wheel, and the position of the pressing wheel corresponds to that of the load-bearing wheel. The adjusting rod drives the pressing wheel to displace, changing the distance between the two pressing wheels.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: It is powered by an external power supply. The operator starts the device through an external control device, places the two ends of the steel pipe on the upper sides of two load-bearing wheels respectively, starts the motor in the built-in groove to drive the second threaded rod to rotate, and the second threaded rod drives the displacement of the built-in sleeve through threading. The built-in sleeve drives two pressing wheels to adjust the distance through the adjusting rod, realizing the change of the processing position. Then, start the motor in the drive box to drive the first threaded rod to rotate. The first threaded rod drives the sliding sleeve through threading to drive the bracket on the hydraulic rod to displace. The bracket drives the load-bearing wheel to displace to adapt to the position of the pressing wheel. Then, start the hydraulic rod to drive the load-bearing wheel to rise. The load-bearing wheel drives the steel pipe to rise. When the upper side of the steel pipe is clamped inside the pressing wheel, the middle part of the steel pipe remains unchanged. The two ends of the steel pipe are deformed due to the extrusion of the load-bearing wheel and the limitation of the pressing wheel. The bending angle is controlled according to the rising height of the hydraulic rod. The structure of this device is simple and the operation is convenient. Through the double-head synchronous bending design, the processing efficiency of the device is ensured. At the same time, the single-side hydraulic rod can also be started to realize single-head bending, and the operability is strong. Through the design of adjustable bending position and angle, the practicability of the device is improved. Brief Description of the Drawings
