[0024] This specific implementation is a foolproof material bar double-end bending device, and its structural schematic diagram is as follows Figure 1-Figure 6 As shown, it includes a workbench 1, a mold base 2 is installed on the top of the workbench 1, a mounting plate 3 is installed on the top of the mold base 2, a mold 4 is arranged above the mounting plate 3, the mold 4 is installed on the top of the mold base 2, and a positioner 6 is installed on the mounting plate 3. There are two positioners 6 and they are respectively located on the left and right sides of the mold 4. A pulley 7 is installed on one side of the positioner 6. A mold groove 5 is opened on the top of the mold 4. A cylinder 8 is fixedly connected to the top of the workbench 1 near the left side, and the telescopic end of the cylinder 8 is movably connected to the top of the mounting plate 3. An anti-fool device 9 is installed on the top of the workbench 1, and the anti-fool device 9 is located on the right side of the mold groove 5. A vertical plate 10 is fixedly connected to the top of the workbench 1 near the right side, and a positioning and fixing mechanism is installed on the left side wall of the vertical plate 10.

[0025] The fool-proofing device 9 in the present technical solution is to ensure the accuracy of the processed accessories. The material rod must be placed in the mold groove 5, and one end of the material rod must be pushed to contact the feeler rod on the fool-proofing device 9. After contacting the feeler rod of the fool-proofing device 9, the position of the material rod is the optimal position, which can make the bending of the material rod more accurate.

[0026] like Figure 3-Figure 4As shown, the fixing mechanism includes a cross bar 11, a connecting plate 12 is movably connected to the front side wall of the cross bar 11, one side of the connecting plate 12 is fixedly connected to the vertical plate 10, a pressing plate 13 is fixedly connected to the bottom of the cross bar 11 near the right side, and the pressing plate 13 is L-shaped. A rectangular opening 16 is opened near the left side of the top of the cross bar 11, and a push rod 17 is movably connected between the front and rear inner walls of the rectangular opening 16. The top and bottom of the push rod 17 extend to the outside of the rectangular opening 16 respectively. A sliding tube 18 is sleeved on the side wall of the cross bar 11, and a U-shaped plate 20 is sleeved on the side wall of the sliding tube 18. The front and rear inner walls of the U-shaped plate 20 are movably connected to the outer wall of the sliding tube 18. An electric telescopic rod 21 is fixedly connected to the top of the U-shaped plate 20, and a fixing plate 22 is movably connected to the side wall of the electric telescopic rod 21 near the right side. One side of the fixing plate 22 is fixedly connected to the vertical plate 10, and the front and rear side walls of the U-shaped plate 20 are respectively movably connected with connecting rods 19, and the opposite sides of the two connecting rods 19 are respectively movably connected to the push rods 17.

[0027] The fixing mechanism can press the material rod and push it to slide to the right, so that the material rod contacts the touch rod on the anti-fool device 9, effectively achieving the purpose of not requiring the staff to manually press the material rod, thereby improving work efficiency and safety. The electric telescopic rod 21 is a relatively mature device in the prior art and is common knowledge, so it will not be introduced in detail in the technical solution.

[0028] Among them, a movable groove 14 is opened near the left side of the top of the pressing plate 13, and a groove wheel 15 is movably connected between the front and rear inner walls of the movable groove 14. Through the groove wheel 15, the push rod 17 can push the material rod to slide to the right while pressing the material rod.

[0029] In addition, a baffle 24 is fixedly connected to the top of the cross bar 11, a rectangular plate 23 is fixedly connected to the top of the slide tube 18, and a spring 25 is fixedly connected between the rectangular plate 23 and the baffle 24. The spring 25 can prevent the slide tube 18 from shifting first when the cross bar 11 descends. When the groove wheel 15 contacts the material rod and cannot continue to move downward, the slide tube 18 will push the spring 25 to compress, causing the push rod 17 to swing.

[0030] Among them, a rubber pad 26 is fixedly connected to the side of the push rod 17 opposite to the mold 4 near the bottom. The rubber pad 26 is arranged in an arc shape, and the rubber pad 26 can prevent the push rod 17 from damaging the material rod.

[0031] Among them, the bottom of the inner cavity of the mold groove 5 is set in a concave arc, and the groove wheel 15 matches the mold groove 5. Because the bottom of the inner cavity of the mold groove 5 is set in an arc shape, the groove on the groove wheel 15 is also set in an arc shape. The two are put together in a circular setting, which can better fit the material rod and prevent the material rod from being clamped.

[0032] Working principle: When using this technical solution, first connect the cylinder 8 to the air compressor, then place the material rod in the mold groove 5, and start the electric telescopic rod 21 by controlling the power supply. The electric telescopic rod 21 pushes the cross bar 11 to swing downward through the U-shaped plate 20 and the slide tube 18, so that the groove wheel 15 contacts the material rod. When the groove wheel 15 drops to the limit, the electric telescopic rod 21 will continue to push the slide tube 18 to move left to compress the spring 25, so that the connecting rod 19 pushes the push rod 17 to swing counterclockwise to achieve the effect of contacting the rubber pad 26 with the left end of the material rod. At this time, the electric telescopic rod 21 continues to push the slide tube 18 forward to compress the spring 25, so that the push rod 17 pushes the material rod to slide to the right and contact the anti-fool device 9. The contacts are in contact, which will trigger the control start to push the mounting plate 3 to rotate counterclockwise. The mounting plate 3 will simultaneously drive the positioner 6 and the pulley 7 to rotate counterclockwise, so that the pulley 7 contacts the material rod and bends it to complete the bending work. After completion, the electric telescopic rod 21 is retracted by controlling the power supply, and the cross bar 11 is pulled upward by the U-shaped plate 20. Synchronously, the sliding tube 18 is pushed to the right by the rebound force of the spring 25, so that the push rod 17 swings to the left and returns to the initial position. Next, as the electric telescopic rod 21 continues to pull the cross bar 11 up, the groove wheel 15 also rises and disengages from the processed accessories. The above operation can effectively solve the problem of safety hazards caused by pressing the accessories by hand during processing.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
