DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example:

[0024] like Figures 1 to 6 As shown, the present embodiment provides a bending device for railway rigid material embedded parts, comprising a workbench 1, a limiting assembly 2, a pressing assembly 3 and a bending assembly 4. The limiting assembly 2, the pressing assembly 3 and the bending assembly 4 are arranged in sequence along the left-right center line of the top of the workbench 1. An anchor bolt 5 to be processed is placed along the left-right center line of the workbench 1. The bending part of the anchor bolt 5 is placed between the bending assembly 4 and the pressing assembly 3. The bending assembly 4 is pressed against the lower surface of the anchor bolt 5, and the pressing assembly 3 is pressed against the upper surface of the anchor bolt 5. The portion of the anchor bolt 5 that is not pressed by the pressing component 3 is bent, a heating element 6 is provided at the contact portion between the bending component 4 and the anchor bolt 5, the pressing element of the pressing component 3 can adjust the horizontal distance between the anchor bolt 5 and the bending component 4, the end of the anchor bolt 5 away from the bending portion is fixed by the limiting component 2, the limiting component 2 is provided with a limiting element A7 that moves in the vertical direction and a limiting element B8 that moves in the front and rear directions, the limiting component 2 limits the anchor bolt 5 to the center line of the workbench 1 by pressing from above by the limiting element A7 and clamping from the front and rear sides by the limiting element B8.

[0025] Through the adjustable pressing component 3 and the limiting component 2, the anchor bolts 5 of different thicknesses can obtain a better bending effect, and the application range is wide; when bending, the pressing component 3 presses on the left side of the anchor bolt 5 at the bending part, and the bending component 4 turns on the right side of the anchor bolt 5 at the bending part. The larger the cross-sectional diameter of the anchor bolt 5, the larger the distance between the bending part of its upper surface and the bending part of its lower surface. The pressing part of the pressing component 3 can adjust the distance between it and the bending component 4 according to the thickness of the anchor bolt 5. , let the pressing part and the bending component 4 align with the corresponding bending part on the anchor bolt 5 to prevent the bending part from deviating from the preset position. The limiting component 2 limits the remaining parts of the anchor bolt 5 to the center line of the workbench 1 to prevent the anchor bolt 5 from sliding and deviating during bending and affecting the bending effect. The limiting parts A7 and B8 on the limiting component 2 can adjust their positions according to the thickness of the anchor bolt 5, so that the limiting parts A7 and B8 are tightly against the outer wall of the anchor bolt 5, and the bending effect is guaranteed by improving the limiting effect. The bending component 4 heats the bending part of the anchor bolt 5 through the heating part 6, which reduces the difficulty of bending, reduces the probability of cracks at the bending part, and improves the bending effect.

[0026] Furthermore, the limit assembly 2 also includes a fixed frame A9, a screw A10, a bidirectional screw rod 11 and a turning handle 12. The workbench 1 is provided with a fixed frame A9, and the fixed frame A9 is threadedly connected with the screw A10 in the vertical direction and is rotatably connected with the bidirectional screw rod 11 in the front and rear directions. The outer ends of the screw A10 and the bidirectional screw rod 11 are respectively coaxially connected with the turning handle 12, and the bidirectional screw rod 11 is symmetrically provided with a limit member B8 in front and back, and the limit member B8 is threadedly connected to the bidirectional screw rod 11. The fixed frame A9 is provided with a slideway 13 parallel to the bidirectional screw rod 11, and the limit member B8 is provided with a slider 14 slidably connected to the slideway 13. The bottom end of the screw A10 is rotatably connected to the limit member A7, and the limit member B8 is provided with a through opening 15 in the vertical direction. The left and right ends of the limit member A7 are respectively slidably connected to the corresponding through opening 15.

[0027] When the user turns the handle 12, the screw A10 or the bidirectional screw 11 connected thereto is driven to rotate, and the screw A10 is threadedly connected to the fixing frame A9. The rotating screw A10 moves up and down along the screw hole of the fixing frame A9 into which it is screwed, thereby changing the height of the limiter A7 connected to the screw A10. The limiter B8 is restricted to move in the front and rear directions by the slider 14 and the slideway 13. The rotating bidirectional screw 11 can drive the two limiters B8 threaded thereto to move in the opposite direction synchronously, and the purpose of adjusting the positions of the limiters A7 and the limiters B8 according to the thickness of the anchor bolt 5 is achieved in two ways. The through opening 15 on the limiter B8 guides the left and right ends of the limiter A7, limiting the rotation ability of the limiter A7, and preventing the limiter A7 from rotating when it is tightly against the anchor bolt 5, thereby affecting its limiting effect.

[0028] Furthermore, the pressing assembly 3 includes a fixed frame B16, a screw B17, a turning handle 12, a lifting plate 18, a guide rod 19, a pressure block 20 and a fixing screw 21. A fixed frame B16 is provided on the workbench 1. The fixed frame B16 is threadedly connected with a screw B17 along the vertical direction. The top of the screw B17 is provided with a turning handle 12. The bottom of the screw B17 is rotatably connected with a lifting plate 18. The lifting plate 18 is provided with a guide rod 19 along the vertical direction. The fixed frame B16 is provided with a guide hole 22 for the guide rod 19 to pass through. The bottom of the lifting plate 18 is slidably connected with a pressure block 20. The pressure block 20 slides in the left and right directions. The lifting plate 18 is threadedly connected with a fixing screw 21, and the fixing screw 21 can be screwed down to tightly press against the top of the pressure block 20.

[0029] The user rotates the handle 12 to drive the connected screw B17 to rotate. The rotating screw B17 moves up and down along the screw hole of the fixing frame B16 into which it is screwed, thereby changing the height of the lifting plate 18 connected to the screw B17 and the pressing block 20 under the lifting plate 18. Due to the guiding effect of the guide rod 19 and the guide hole 22 on the lifting plate 18, the lifting plate 18 does not rotate with the rotation of the screw B17, so that the direction of the pressing block 20 is fixed, which is convenient for the user to judge the landing point of the pressing block 20. After the pressing block 20 slides to a suitable position under the lifting plate 18, the fixing screw 21 is tightened against the pressing block 20, and the position of the pressing block 20 is fixed by the friction between the fixing screw 21 and the pressing block 20.

[0030] Furthermore, the bending assembly 4 includes a rotating plate 23, a telescopic rod 24, a lifting rod 25, a support wheel 26 and a wheel track 27. The workbench 1 is provided with an installation opening 28 that is connected to each other from top to bottom on the right side of the pressing assembly 3. The rotating plate 23 is hinged on the left side of the installation opening 28. A wheel track 27 is provided at the bottom of the rotating plate 23. A telescopic rod 24 along the vertical direction is provided below the installation opening 28. A lifting rod 25 is provided at the top of the movable rod of the telescopic rod 24. The end of the lifting rod 25 is rotatably connected to a support wheel 26, and the support wheel 26 rolls along the wheel track 27. When the support wheel 26 is located at one end of the wheel track 27 close to the hinge of the rotating plate 23, the rotating plate 23 is flush with the top of the workbench 1. When the support wheel 26 is located at one end of the wheel track 27 away from the hinge of the rotating plate 23, the rotating plate 23 rotates up to be perpendicular to the top of the workbench 1.

[0031] The height of the support wheel 26 is adjusted by the telescopic rod 24, and the support wheel 26 squeezes the wheel track 27 to drive the rotating plate 23 to rotate. The rotating plate 23 that rotates upward can bend the part of the anchor bolt 5 that is abutted by the rotating plate 23 to complete the bending operation.

[0032] Furthermore, a heating element 6 is provided on the top of the workbench 1 on the left side of the installation opening 28, and the heating element 6 on the workbench 1 is adjacent to the heating element 6 on the bending assembly 4. The two heating elements 6 leaning against the bending part of the anchor bolt 5 improve the heating effect on the bending part of the anchor bolt 5.

[0033] Furthermore, the heating element 6 includes a heat conducting plate 29 and an electric heater 30. The heat conducting plate 29 is flush with the mounting surface thereof, the outer side of the heat conducting plate 29 abuts against the anchor bolt 5, and the electric heater 30 is arranged inside the heat conducting plate 29. The electric heater 30 generates heat inside, and the heat is transferred to the anchor bolt 5 abutted thereon through the heat conducting plate 29.

[0034] The working principle and use process of this utility model:

[0035] The user places the anchor bolt 5 along the center line of the workbench 1, aligns the bending part of the lower surface of the anchor bolt 5 with the bending component 4, adjusts the horizontal position of the pressing block 20 so that its landing point is aligned with the bending part of the upper surface of the anchor bolt 5, drops the pressing block 20 to press the anchor bolt 5, operates the limiting component 2 to limit the position of the anchor bolt 5 away from the bending part, and then operates the bending component 4 to bend the anchor bolt 5 upward, and finally resets the limiting component 2, the pressing component 3 and the bending component 4, and takes away the bent anchor bolt 5.

[0036] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
