Description

Technical Field

[0001] This utility model relates to the field of steel pipe bending processing technology, specifically a steel pipe bending processing device. Background Technology

[0002] Steel pipe bending processing equipment is a specialized device used to bend steel pipes into various shapes according to specific requirements. It is widely used in construction, machinery manufacturing, and the automotive industry. However, existing steel pipe bending processing equipment still has some shortcomings, such as:

[0003] The steel pipe bending processing device described in application number CN202122609410.4 is a tabletop structure. As a bending processing component, it not only depends on the site in actual use, but also does not have an angle adjustment component, which makes it impossible for the device to accurately control the bending. Utility Model Content

[0004] The purpose of this utility model is to provide a steel pipe bending processing device to solve the problem mentioned in the background art that the existing equipment on the market adopts a table-type structure as the bending processing component, which not only depends on the site in actual use, but also does not have an angle adjustment component, resulting in the equipment being unable to accurately control the bending.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe bending processing device, comprising a bending frame, a turntable, a bending roller, a rack and a control valve;

[0006] The bending frame is equipped with a hydraulic pedal and a control valve on its side;

[0007] A hydraulic head, a reversing gear, and a support frame are installed above the bending frame. A turntable, a bending roller, and a rack are provided on the side of the reversing gear, and a screw is provided on the side of the turntable.

[0008] As a preferred technical solution of this utility model, the bottom of the bending frame is a trapezoidal structure, and the bending frame is divided into two parts: the part on the left side of the center line of the bending frame is a hydraulic component, and the part on the right side of the center line is a support structure.

[0009] The above technical solution features a trapezoidal bottom structure for the bending frame. This design increases the overall stability of the device, ensuring stability even under significant external forces during steel pipe bending operations, preventing the device from swaying or tipping over. The bending frame is divided into two parts: a hydraulic assembly on the left side of the frame's centerline, providing power support, and a support structure on the right side, used to support and fix other components. This rational structural division helps improve the collaborative working efficiency of the various parts of the device.

[0010] As a preferred technical solution of this utility model, a hydraulic pedal is rotatably connected to the lower left side of the bending frame, a control valve is fixedly connected to the upper parallel position above the hydraulic pedal, the upper surface of the bending frame is slidably connected to the hydraulic head, and an annular groove is formed on the outer side of the hydraulic head.

[0011] Using the above technical solution, a hydraulic pedal is rotatably connected to the lower left side of the bending frame, allowing operators to easily control the hydraulic system by stepping on it. Operation is simple and convenient. A control valve is fixedly connected above the hydraulic pedal at a parallel position, enabling operators to quickly and accurately adjust the control valve while stepping on the pedal, achieving precise control of the hydraulic system's pressure and flow. The upper surface of the bending frame is slidably connected to the hydraulic head. This sliding connection allows the hydraulic head to move smoothly on the bending frame, ensuring uniform pressure application during bending. An annular groove is formed on the outer side of the hydraulic head, which can be used to install sealing elements, enhancing the sealing of the hydraulic system, preventing hydraulic oil leakage, and improving the device's operational reliability.

[0012] As a preferred embodiment of this utility model, the side of the bending frame is hinged to the support frame, and the support frame is composed of two connecting rods. The support frame is rotatably connected to the bending roller, and there are two symmetrically distributed support frames.

[0013] Using the above technical solution, the side of the bending frame is hinged to the support frame, and the support frame consists of two connecting rods. This structural design allows the support frame to rotate flexibly to adapt to the bending requirements of steel pipes of different diameters. The support frame is rotatably connected to the bending roller, which facilitates the smooth rotation of the bending roller during the bending process, reduces friction between the steel pipe and the bending roller, and improves the bending quality. There are two symmetrically distributed support frames. The symmetrical distribution design ensures that the steel pipe is subjected to uniform force during the bending process, thus guaranteeing bending accuracy.

[0014] As a preferred technical solution of this utility model, the bending frame is made of cast iron and covered with a high-strength paint coating.

[0015] Using the above technical solution, the bending frame is made of cast iron with a high-strength paint coating. Cast iron has good compressive strength and wear resistance, and can withstand the large pressure generated during the bending of steel pipes, thus extending the service life of the device. The high-strength paint coating not only serves an aesthetic purpose, but also effectively prevents the cast iron from rusting and corroding, further improving the durability of the device.

[0016] As a preferred technical solution of this utility model, the bending frame is slidably connected to a rack on its side, the rack is meshed with a reversing gear, and the reversing gear is fixedly connected to a support frame;

Cast iron has good compressive strength and wear resistance, and can withstand the large pressure generated during the bending of steel pipes, thus extending the service life of the device. The high-strength paint coating not only serves an aesthetic purpose, but also effectively prevents the cast iron from rusting and corroding, further improving the durability of the device.

[0018] As a preferred embodiment of this utility model, the rack is threadedly connected to the screw at the bottom, a gear structure is fixed at the top of the screw, and the gear at the top of the screw meshes with a gear structure provided at the bottom of the turntable. The turntable is rotatably connected to the bending frame.

[0019] Using the above technical solution, the movement of the hydraulic head is controlled by the hydraulic pedal and control valve. The hydraulic head pushes the rack to move, the rack drives the reversing gear to rotate, and the reversing gear drives the support frame and bending roller to rotate, thus bending the steel pipe placed on the bending roller. At the same time, the operator can precisely adjust the bending angle of the bending roller by rotating the turntable and using the threaded connection between the screw and the rack to meet different processing requirements.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Improved bending efficiency: The application of the hydraulic system provides powerful force, making the steel pipe bending process faster and significantly shortening the processing time compared to the traditional manual bending method.

[0022] 2. It ensures bending accuracy. Through gear and rack transmission and adjustable bending angle design, it can accurately control the bending angle of steel pipes, meet various high-precision processing requirements, and reduce scrap rate.

[0023] 3. Simple and convenient operation: Operators only need to step on the hydraulic pedal and rotate the turntable to complete complex bending operations, which reduces the technical requirements for operators, improves production efficiency, and the overall size of the equipment is small and easy to carry.

[0024] 4. The device has good stability and durability. The use of trapezoidal bending frame and cast iron material, as well as reasonable component connection method, enables the device to remain stable during long-term use, reduce failures and lower maintenance costs. Attached Figure Description

This structural design increases the overall stability of the device. When bending steel pipes, even under large external forces, it can remain stable and prevent the device from shaking or tipping over. The bending frame 1 is divided into two parts: the part on the left side of the center line of the bending frame 1 is the hydraulic assembly, which is responsible for providing power support, and the part on the right side is the support structure, which is used to support and fix other components.

The upper surface of the bending frame 1 is slidably connected to the hydraulic head 5. This sliding connection allows the hydraulic head 5 to move smoothly on the bending frame 1, ensuring pressure application during bending. To improve uniformity, an annular groove is formed on the outer side of the hydraulic head 5. This groove allows for the installation of sealing elements, enhancing the sealing of the hydraulic system, preventing hydraulic oil leakage, and improving the reliability of the device.

The rack 4 is threadedly connected to the screw 8 at its lower end, with a gear structure fixed to the top of the screw 8. This gear meshes with a gear structure at the bottom of the turntable 2. The turntable 2 is rotatably connected to the bending frame 1. The movement of the hydraulic head 5 is controlled by the hydraulic pedal 9 and the control valve 10. The hydraulic head 5 pushes the rack 4, which in turn drives the reversing gear 6 to rotate. The reversing gear 6 drives the support frame 7 and the bending roller 3 to rotate, performing a bending operation on the steel pipe placed on the bending roller 3. Simultaneously, the operator can precisely adjust the bending angle of the bending roller 3 by rotating the turntable 2, utilizing the threaded connection between the screw 8 and the rack 4, to meet different processing requirements.

[0035] Working principle: When using a steel pipe bending processing device, first rotate the turntable 2, which drives the screw 8 to move and pull the rack 4 downward. During the downward movement of the rack 4, the support frame 7 is rotated upward under the drive of the reversing gear 6 until it reaches the appropriate position. The steel pipe to be processed is then passed between the support frame 7 and the hydraulic head 5. The hydraulic cylinder is started by using the hydraulic pedal 9 to continuously raise the hydraulic head 5 and begin the bending operation until the steel pipe reaches the appropriate angle. The pressure is released by the control valve 10, and the hydraulic head 5 is retracted to remove the steel pipe.
