[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figure 1-5 As shown, this utility model provides a technical solution: an intelligent three-station cold bending tester, including a support base 1 and an instrument body 2. The instrument body 2 is mounted on the top of the support base 1, and a control panel 3 is embedded in the front edge of the instrument body 2. Mounting supports 4 are fixedly connected to both sides of the top of the support base 1, and hydraulic cylinders 5 are fixedly embedded in the inner side of the mounting supports 4. A sliding groove 6 is opened on the inner side of the top of the support base 1, and a movable slider 7 is connected to the telescopic end of the hydraulic cylinder 5. The top side of the movable slider 7 is embedded in a connecting... The instrument body 2 is equipped with a pressure support roller 8. The telescopic end of the main hydraulic cylinder in the middle of the inner side of the instrument body 2 is connected to a hydraulic rod 17. The hydraulic cylinder 5 drives the moving slider 7 to slide along the sliding groove 6. The main hydraulic cylinder in the middle of the inner side of the instrument body 2 drives the hydraulic rod 17 to slide up and down. The position of the hydraulic rod 17 corresponds to the center position of the sliding groove 6, which facilitates the cold bending of the workpiece placed on the two pressure support rollers 8. The bottom end of the hydraulic rod 17 is detachably connected to a pressure roller seat 18. The bottom end of the pressure roller seat 18 is connected to a cold bending pressure roller 19. The support base 1 has a material discharge channel 9 at the sliding groove 6 inside, and the discharge end of the support base 1 corresponding to the material discharge channel 9 is connected to a feeding inclined channel 10. Connecting seats 11 are fixedly connected to the inner walls of both the front and rear sides of the material discharge channel 9. Rotating support plates 12 are rotatably connected to the inner side of the connecting seats 11. Flexible buffer pads 13 are adhered to the top surface of the rotating support plates 12. Support plates 14 are fixedly connected to the inner walls of the material discharge channel 9 and the inner sides of the rotating support plates 12. Several sets of inclined support springs 15 are equidistantly installed on the support plates 14. The rotating support plates 12 are rotatably connected to the inner side of the connecting seats 11 via a rotating shaft. The two rotating support plates 12 on the inner walls of the front and rear sides of the material discharge channel 9 form a 120-degree angle under the support of the inclined support springs 15. The two ends of the inclined support springs 15 are fixedly connected to the edges of the material discharge channel 9 and the rotating support plates 12, respectively. On the support plate 14, the rotating support plate 12 is easily connected to the rotation, and the rotating support plate 12 is easily elastically supported by the inclined support spring 15. Several sets of rotating rubber rollers 16 are equidistantly embedded and rotatably connected on the top inclined surface of the feeding inclined channel 10. The top inclined surface of the feeding inclined channel 10 is provided with a fitting groove. The rotating rubber rollers 16 are rotatably connected in the fitting groove through a movable shaft. The discharge end of the feeding inclined channel 10 extends to the outside of the support base 1, which facilitates the insertion and rotation of the rotating rubber rollers 16. The rotating rubber rollers 16 facilitate secondary pressure buffering of the workpiece when it falls for the second time. At the same time, the rotation of the rotating rubber rollers 16 facilitates the direct output of the workpiece to the outside of the instrument.

[0017] The bottom end of the hydraulic rod 17 is fixedly connected to the plug seat 20, and the top end of the pressure roller seat 18 is fixedly connected to the limit plate 21. The top end of the limit plate 21 is inserted into the plug seat 20 through the wedge block 22. An adsorption magnetic block 23 is provided on the inner top surface of the plug seat 20. Both the connector 20 and the mating block 22 have through-grooves 24. A mating pin 25 is embedded in the inner side of the through-grooves 24. The end of the mating pin 25 is detachably connected to the front edge of the connector 20 by a set bolt 26.

After the mating block 22 is fully inserted into the connector 20, the positions of the through-grooves 24 inside the connector 20 and the mating block 22 correspond. The cooperation of the through-grooves 24 and the mating pin 25 makes it easy to lock and limit the position of the connector 20 and the mating block 22. The set bolt 26 then limits the end of the mating pin 25.

[0018] The working principle and usage process of this utility model: In the actual application of this intelligent three-station cold bending tester, it is first necessary to select a suitable cold bending pressure roller 19 according to the actual cold bending test requirements. After selecting a suitable cold bending pressure roller 19, it is necessary to install it. By connecting the wedge block 22 at the bottom of the hydraulic rod 17, combined with the limiting plate 21 and the plug-in seat 20 at the top of the pressure roller seat 18, it is convenient to quickly plug and assemble the pressure roller seat 18 with the bottom of the hydraulic rod 17. The magnetic adsorption block 23 facilitates the initial magnetic adsorption and limiting of the top of the wedge block 22. Combined with the alignment slot 24 and the engagement pin 25, it is convenient to further lock and limit the position between the plug-in seat 20 and the engagement block 22. Combined with the set bolt 26 to limit the end of the engagement pin 25, it ensures the stability of the connection between the engagement pin 25 and the plug-in seat 20 and the engagement block 22. In this way, the cold bending roller 19 and the hydraulic rod 17 can be easily assembled through a quick plug-in assembly method. The operation is convenient and it is also convenient to select the appropriate cold bending roller 19 for easy replacement and installation according to the actual test needs. After the cold bending roller 19 is selected and assembled, the hydraulic cylinder 5 drives the moving slider 7 and the pressure support roller 8 to slide along the sliding groove 6, which facilitates the adjustment of the position of the two pressure support rollers 8. Then, the workpiece to be cold bent is placed on the two pressure support rollers 8. After the cold bending position is determined, the main hydraulic cylinder and hydraulic cylinder 5 are controlled by the control panel 3 to adjust the extension and retraction of the main hydraulic cylinder and hydraulic cylinder 5. The main hydraulic cylinder in the instrument body 2 drives the hydraulic rod 17, the pressure roller seat 18, and the cold bending roller 19 to rise and fall, so as to perform cold bending on the workpiece placed on the two pressure support rollers 8. After the workpiece is continuously pressed by the cold bending roller 19, the workpiece is transformed into a U-shape after cold bending. Combined with the reset of the moving slider 7 and the pressure support roller 8, the workpiece after the cold bending test can fall into the material dropping channel 9 at the bottom of the sliding groove 6 under its own gravity. Combined with the feeding tilt channel 10, it is convenient to automatically output the workpiece to the outside of the instrument, avoiding frequent manual operation and preventing safety hazards. When the workpiece falls into the discharge channel 9, the rotating support plate 12 is rotatably connected to the inner side of the connecting seat 11, and the inclined support spring 15 supports the rotating support plate 12. Combined with the flexible buffer pad 13 on the top of the rotating support plate 12, the flexible buffer pad 13 and the inclined support spring 15 can effectively buffer and dilute the impact force of the workpiece falling into the discharge channel 9, thereby avoiding impact damage when the workpiece falls. When the workpiece falls into the feeding inclined channel 10 through the two rotating support plates 12 from the dropping channel 9, several sets of rotating rubber rollers 16 connected to the top inclined surface of the feeding inclined channel 10, combined with the pressure bearing effect of the rotating rubber rollers 16 themselves, achieve secondary pressure bearing and buffering treatment on the workpiece when it falls. Combined with the rotational conveying effect of the rotating rubber rollers 16, it is convenient to output the workpiece stably. Finally, when it is necessary to disassemble and replace the cold bending roller 19 at the bottom of the hydraulic rod 17, first remove the set bolt 26, release the limit of the mating pin 25, and pull the mating pin 25 out of the alignment slot 24. This will release the limiting connection between the mating block 22 and the plug seat 20, making it easier to assemble the new cold bending roller 19 later.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
