Description

Technical Field

[0001] This utility model relates to the field of bending and forming equipment technology, specifically to a precision bending and forming equipment for electromagnetic valve bearing tubes. Background Technology

[0002] The solenoid valve bearing tube is the pipe used when using a solenoid valve. The solenoid valve bearing tube (also called the guide tube or valve core sleeve) is a key component of the solenoid valve, and its bending accuracy directly affects the smoothness of the valve core's movement and sealing performance.

[0003] Existing solenoid valve bearing tube bending equipment typically uses fixed molds or a single bending mechanism, which has the following problems: poor adaptability: existing equipment is usually only suitable for bearing tubes of a specific diameter. When it is necessary to bend pipes of different diameters, the mold must be changed or the mechanical structure adjusted, which is cumbersome and affects production efficiency. Low bending accuracy: due to the lack of an adaptive adjustment mechanism, when bending pipes of different diameters, uneven clamping force or bending radius deviation can easily lead to pipe deformation and excessive ovality, affecting the assembly and performance of the solenoid valve.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a precision bending and forming device for electromagnetic valve bearing tubes.

[0027] This utility model provides, for example Figure 1-4 The device shown is a precision bending and forming equipment for electromagnetic valve bearing tubes, including a machine tool 1. An L-shaped support seat 2 is fixedly connected to the side wall of the machine tool 1. A first support slide plate 3 and a second support slide plate 4 are fixedly connected to the top of the machine tool 1 and the L-shaped support seat 2 respectively through a moving mechanism. A rotary pneumatic chuck device 5 is fixedly connected to the top of the first support slide plate 3. A force-bearing baffle 6 is fixedly connected to the top of the second support slide plate 4. A multi-arc radius groove 7 is opened on the side wall of the force-bearing baffle 6.

[0028] A U-shaped positioning seat 8 is fixedly connected to the top of the other end of the L-shaped support seat 2. A support chamber 9 is fixedly connected to the top of the U-shaped positioning seat 8 via a drive positioning support mechanism. A support shaft 10 is rotatably connected inside the cavity of the support chamber 9. A motor 11 is fixedly connected to one end of the cavity of the support chamber 9. One end of the motor 11 is fixedly connected to the bottom of the support shaft 10. A multi-radius mold device 12 is fixedly connected to the top of the support shaft 10. A support arm 13 is fixedly connected to the rod wall of the support shaft 10. A first hydraulic cylinder 14 is fixedly connected to the side wall of the support arm 13. One end of 14 passes through the side wall of the support arm 13 and is fixedly connected to a multi-radius clamping plate 15. The multi-radius clamping plate 15 corresponds to the multi-radius mold device 12. Using the provided rotary pneumatic chuck device 5, the clamping force and range can be flexibly and precisely adjusted according to the diameter of the solenoid valve bearing pipe. The multi-arc radius groove 7 works in conjunction with the multi-radius mold device 12 to provide a precisely matched bending path and support for the pipe according to different bending radius requirements. During the bending process, it can effectively prevent the pipe from being damaged due to bending radius deviation. To prevent material deformation and excessive ovality, and to ensure pipe bending accuracy and improve product quality, the first hydraulic cylinder 14 pushes the multi-radius clamping plate 15 to tightly fit the multi-radius mold device 12. During pipe bending, pressure is applied evenly to the pipe, avoiding damage caused by uneven clamping force, maintaining the shape stability of the pipe during bending, reducing the risk of pipe deformation, and further ensuring bending accuracy. The moving mechanism can drive the first support slide plate 3 and the second support slide plate 4 to move flexibly, achieving precise adjustment of the pipe position. The set drive positioning support mechanism can accurately control the horizontal position of the support chamber 9, making it easy to adjust the grooves of different radii in the multi-radius mold device 12 and the multi-radius clamping plate 15 to be consistent with the current steel pipe level for bending work. This improves the overall accuracy and stability of pipe bending and forming, thereby solving the problem that existing electromagnetic valve bearing pipe bending equipment is not suitable for pipes of different thicknesses and is prone to pipe deformation and excessive ovality due to uneven clamping force or bending radius deviation, resulting in low bending accuracy.

[0029] In order to move the rotary pneumatic clamping device 5 and the force-baffle 6, such as Figure 1-3As shown, the moving mechanism includes a guide rail compartment 16, an electric push rod 17, and a sliding opening 18. One end of each guide rail compartment 16 is fixedly connected to an electric push rod 17, and the surface of each guide rail compartment 16 is provided with a sliding opening 18. The first support slide plate 3 and the second support slide plate 4 are slidably connected to the corresponding sliding openings 18 at both ends, and are fixedly connected to one end of the corresponding electric push rod 17. By using the moving mechanism composed of the guide rail compartment 16, the electric push rod 17, and the sliding opening 18, the electric push rod 17 at both ends pushes the corresponding first support slide plate 3 and the second support slide plate 4 to slide in the sliding opening 18, thereby driving the rotating pneumatic clamping device 5 and the force-baffle 6 on the top of the first support slide plate 3 and the second support slide plate 4 to move.

[0030] In order to allow the support chamber 9 and other structures to move vertically, such as...

The side walls of the two end positioning slide plates 20 are fixedly connected to the side walls of the support chamber 9. The second hydraulic cylinder 21 is fixedly connected in the bottom cavity of the U-shaped positioning seat 8. One end of the second hydraulic cylinder 21 is fixedly connected to the bottom of the support chamber 9. By using the drive positioning support mechanism composed of the limiting slide 19, the positioning slide plate 20, and the second hydraulic cylinder 21, the support chamber 9 and other structures can move up and down in coordination with the limiting slide 19 and the positioning slide plate 20 under the push of the second hydraulic cylinder 21, so as to adjust the position and make it easy to adjust the grooves of different radii in the multi-radius mold device 12 and the multi-radius clamping plate 15 to be consistent with the current steel pipe for bending work.

[0031] To facilitate bending of pipes of different diameters using the multi-radius clamping plate 15, such as... Figure 1 , 2 As shown in Figure 4, the multi-radius mold device 12 includes multiple mold plates 22. The outer walls of the multiple mold plates 22 are respectively provided with small radius grooves 23, medium radius grooves 24 and large radius grooves 25. By using multiple mold plates 22 with small radius grooves 23, medium radius grooves 24 and large radius grooves 25 respectively, it is convenient to cooperate with the multi-radius clamping plate 15 to bend pipes of different diameters.

[0032] To facilitate the bending of pipes of different diameters using the multi-radius mold device 12, such as... Figure 1 , 2As shown in Figure 4, the multi-radius clamping plate 15 includes a clamping plate 26. The side wall of the clamping plate 26 is provided with a small corresponding groove 27, a medium corresponding groove 28 and a large corresponding groove 29 from bottom to top. By using the clamping plate 26 and the small corresponding groove 27, medium corresponding groove 28 and large corresponding groove 29 on the side wall, it can be used in conjunction with the multi-radius mold device 12 to bend pipes of different diameters.

[0033] To reduce mutual wear, such as Figure 1-4 As shown, the surfaces of the force-bearing baffle 6, the multi-radius mold device 12, and the multi-radius clamping plate 15 are all provided with a rubber protective coating. The rubber protective coating is used to protect the force-bearing baffle 6, the multi-radius mold device 12, and the multi-radius clamping plate 15 when they come into contact with the steel pipe, thereby reducing mutual wear.
