Detailed Embodiment

[0018] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or positional relationship, it is only corresponding to the drawings of the present application for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation.

[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: an anchor rod sawing head and tail material positioning and removing device, including a first material rack 1 and a second material rack 3 arranged at intervals. The first material rack 1 and the second material rack 3 are on the same horizontal line and both have positioning grooves for accommodating anchor rods upward; between the first material rack 1 and the second material rack 3, there is a first positioning component 2 for positioning the anchor rod and a sawing component 5 for cutting the anchor rod. On the upper side of one side of the second material rack 3, there is a second positioning component 4 for positioning the anchor rod, and the second material rack 3 is also provided with a removing component 6 for removing the tail material of the anchor rod;

[0020] Specifically, both the first positioning component 2 and the second positioning component 4 include a first cylinder 14, and the telescopic end of the first cylinder 14 is connected with a baffle 11; the removing component 6 includes a second cylinder 10, and the telescopic end of the second cylinder 10 is connected with a pushing block 9. The second material rack 3 is provided with an opening adapted to the pushing block 9;

[0021] When the first positioning component 2 acts, its baffle 11 abuts against the end of the anchor rod. At this time, the distance between the sawing component 5 and the first positioning component 2 is the cutting length of the head material;

[0022] Similarly, when the second positioning component 4 acts, its baffle 11 abuts against the anchor rod from which the head material has been removed. At this time, the distance between the sawing component 5 and the second positioning component 4 is the length of the fixed-length anchor rod to be cut;

[0023] After cutting multiple fixed-length anchor rods, the tail material enters the second material rack 3, and then the tail material is ejected from the second material rack 3 through the action of the removing component 6;

[0024] In actual operation, taking a 9.3-meter-long anchor rod as an example, the head material length is 30 mm, the fixed-length anchor rod is 3 m, and the tail material length is 260 mm. The anchor rod sawing process is: a 30-mm head material, three 3-m finished products, and a 260-mm length tail material. After the tail material is ejected by the next anchor rod, the sum of the tail material length and the head material length is 290 mm. The head material and the tail material are equivalent to the length of the fixed-length anchor rod. Then, the head of the next anchor rod exceeds the saw blade length by about 30 mm, meeting the requirements of the direct sawing process. The removing component 6 ejects the tail material, and continuous sawing processing is carried out in this way;

[0025] Furthermore, the sawing component 5 includes a circular sawing machine 8, and the circular sawing machine 8 is driven by an electric cylinder 7 to cut the anchor rod radially. The electric rod 7 drives the circular sawing machine 8 to move and cut the anchor rod;

[0026] Furthermore, the baffle 11 is an L-shaped plate. The horizontal plate of the baffle 11 is provided with a long groove 13. The telescopic end of the first cylinder 14 passes through the long groove 13 and is locked and fixed by two locking nuts 12. That is, the position of the baffle 11 can be moved to adjust the positions of the first positioning component 2 and the second positioning component 4, and the head material positioning length can be appropriately adjusted as needed;

[0027] Furthermore, the pushing block 9 is a wedge-shaped block, which is convenient for the automatic falling of the pushed material; both the first material rack 1 and the second material rack 3 are angle steels;

[0028] In addition, a material head collection box is provided below between the first material rack 1 and the second material rack 3; a tail material collection box is provided below the second material rack 3 to centrally collect the head material and the tail material.
