[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other. Figure 1-Figure 7 The utility model is described in detail in conjunction with the embodiments.

[0030] A cutting device for engineering material testing includes a workbench 1. A small groove 16 is provided on the tabletop of the workbench 1, which can play a positioning role for a steel bar body 6. The bottom of the steel bar body 6 is just above the small groove 16, and then moves along the direction of the small groove 16. A conveying platform 13 is provided next to the workbench 1, which can convey the steel bar body 6 to the workbench 1. The conveying platform 13 is inclined, and is preferably an intermittent conveying system, and its inclined lower end is arranged above the small groove 16, which is convenient for intermittent feeding of the conveying platform 13. The steel bar body 6 falls intermittently on the tabletop of the workbench 1 below along the conveying platform 13 in sequence, realizing automatic feeding.

[0031] Two sets of push rod assemblies 2 are perpendicularly arranged at both ends of the workbench 1, and a cutting assembly 3 and a fixing assembly 4 are arranged in sequence between the two sets of push rod assemblies 2. The two sets of push rod assemblies 2 each include a vertical plate 14 and a second electric telescopic rod 15. The vertical plate 14 is fixedly arranged on the outer wall of the workbench 1, and the second electric telescopic rod 15 is fixedly arranged on the inner wall of the vertical plate 14. When in use, the second electric telescopic rod 15 is started to realize automatic telescopic extension, thereby playing the role of pushing the steel bar body 6 to move.

[0032] A limit block 17 is fixedly arranged at the outer end of the second electric telescopic rod 15 near the conveying platform 13. The limit block 17 includes a bottom plate 18. The lower end of the bottom plate 18 can slide inside the small groove 16. The upper end of the bottom plate 18 is provided with a circular ring pressure block 19, which can limit and fix the upper half of the steel bar body 6. After the steel bar body 6 falls into the small groove 16 from the conveying platform 13, the second electric telescopic rod 15 is started to drive the limit block 17 to push the steel bar body 6 to move to the left until the inner end of the steel bar body 6 contacts the fixed plate 10 and abuts against each other. The bottom plate 18 is close to the side of the steel bar body 6, and the circular ring pressure block 19 is close to the surface of the upper half of the steel bar body 6, which plays a role in fixing and limiting the outer end of the steel bar body 6.

[0033] Two sections of pipes 5 are arranged on the tabletop of the workbench 1, which can accommodate the passage of the steel bar body 6. The small groove 16 is arranged inside the two sections of pipes 5. One section of the pipe 5 away from the conveying platform 13 is arranged between the cutting component 3 and the fixing component 4, and the length is preferably between 500mm-550mm, which is a length that is more suitable for the steel bar inspection sample. The other section of the pipe 5 is arranged between the cutting component 3 and the limit block 17. The steel bar body 6 enters the pipe 5 under the pushing action of the limit block 17 and moves along the direction of the pipe 5. The pipe 5 can play a fixed limit role on the steel bar body 6 when cutting to prevent it from sliding.

[0034] The fixing assembly 4 includes a fixing plate 10, and a circular pressure block 19 is arranged on the inner wall of the fixing plate 10, which can limit and fix the upper half of the steel bar body 6. The bottom end of the fixing plate 10 is contactably connected with the workbench 1 through an elastic member 11. A cam 12 is rotatably arranged on the top end of the fixing plate 10. The rotation of the cam 12 can make the bottom end of the fixing plate 10 intermittently contact with the workbench 1.

[0035] A group of large grooves 27 and a group of side panels 28 are symmetrically arranged on the tabletop of the workbench 1. A group of slide grooves 29 are symmetrically arranged on the inner wall of the side panels 28. The bottom end of the elastic member 11 is fixedly arranged on the bottom wall of the large groove 27. The elastic member 11 is preferably a plurality of groups of springs. A fixed plate 10 is fixedly arranged on the top of the elastic member 11. Both sides of the fixed plate 10 can slide up and down inside the slide groove 29. A cross bar 30 is fixedly arranged between a group of side panels 28. A movable groove 31 is arranged on the top of the fixed plate 10. The cross bar 30 is provided with a second drive motor 32 through a mounting frame. The cam 12 is arranged at the output end of the second drive motor 32.

[0036] When the inner end of the steel bar body 6 reaches the right side of the fixed plate 10, the time is preset at this time, the cam 12 just rotates to contact with the movable groove 31, the fixed plate 10 is in a stressed state and pressed downward, and the downward pressure makes the elastic member 11 in a compressed state. At this time, the bottom end of the fixed plate 10 is in contact with the table top of the workbench 1, and the inner end of the steel bar body 6, under the push of the second electric telescopic rod 15, applies force to the right side surface of the fixed plate 10 and resists each other. Since the inner wall of the fixed plate 10 is provided with a circular ring pressure block 19, the circular ring pressure block 19 can fix the upper surface of the inner end of the steel bar body 6.

[0037] At this time, the cutting assembly 3 is started to cut the steel bar body 6 to intercept the test sample. The cutting assembly 3 includes a U-shaped frame 7, which is fixedly arranged on the tabletop of the workbench 1, and the two side walls of the U-shaped frame 7 are provided with limit grooves 23, and the top wall of the U-shaped frame 7 is fixedly provided with a first electric telescopic rod 8, and the bottom end of the first electric telescopic rod 8 is provided with a connecting plate 24, and a rotating shaft 25 is provided through the connecting plate 24, and one end of the rotating shaft 25 is provided at the output end of the first driving motor 26, and the other end is fixedly provided with a cutting knife 9, and the two ends of the connecting plate 24 can slide up and down inside the limit groove 23.

[0038] During cutting, the first electric telescopic rod 8 is turned on to drive the connecting plate 24 to move downward along the direction of the limiting groove 23. At the same time, the first driving motor 26 is started to drive the cutting knife 9 to rotate and cut the steel bar body 6. The limiting groove 23 enhances the stability during cutting and makes the incision smooth.

[0039] After the test sample is cut, when the cam 12 just rotates away from the movable groove 31, the fixed plate 10 is not subjected to force, and the elastic member 11 rebounds to a normal state. At this time, the fixed plate 10 moves upward until the gap between the bottom end of the fixed plate 10 and the table top of the workbench 1 can accommodate the steel bar body 6. The test sample of the cut steel bar body 6 and the waste are pushed to the left along the direction of the small groove 16 by the limit block 17 and the second electric telescopic rod 15.

[0040] Since a sample frame 21 and a waste frame 22 are placed beside the workbench 1, a push plate 20 is fixedly arranged at the outer end of another second electric telescopic rod 15, which can push the cut steel bar body 6 into the sample frame 21. The leftmost push rod assembly 2 pushes the test sample into the sample frame 21, and the waste continues to move to the left along the small groove 16 until it falls into the waste frame 22.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
