[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figure 1 As shown, the left side of the figure is the anvil original bar 100, which is a cylindrical bar, and the right side of the figure is the anvil blank 200. The anvil original bar 100 can be formed into the anvil blank 200 by wire cutting.

[0025] This embodiment provides a dowel pin blank cutting tool for limiting and fixing the dowel pin bar during the wire cutting process to facilitate wire cutting.

[0026] like Figure 2 As shown, a dowel seat blank cutting tool comprises a tool body 1, and a row of limit grooves 2 are provided on the surface of the tool body 1. In this embodiment, there are preferably 8 limit grooves. Each limit groove 2 is opened along the axial direction of the tool body 1 and is adapted to the size of the dowel seat original rod 100. An dowel seat original rod 100 can be placed in each limit groove 2. The provision of 8 limit grooves 2 can realize the synchronous wire cutting of 8 dowel seat original rods 100.

[0027] The tool body 1 is provided with a first fixed pressing plate 3 and a second fixed pressing plate 4 at both ends of the limiting groove 2. The anvil original bar 100 is pressed by the first fixed pressing plate 3 and the second fixed pressing plate 4 at both ends to be fixed.

[0028] The first fixed platen 3 is fixed to the tool body 1 via the first fixing bolt 6. Preferably, two first fixing bolts 6 are provided. In addition, the tool body 1 is also provided with a top-loosening spring (not shown in the figure). Preferably, there are two top-loosening springs. Both top-loosening springs are located between the tool body 1 and the first fixed platen 3 and are arranged in a direction perpendicular to the axial direction of the tool body 1. When the first fixing bolt 6 is loosened, the top-loosening spring automatically pushes the first fixed platen 3 open.

[0029] The second fixed pressing plate 4 is provided with a countersunk hole 8 , and the second fixed pressing plate 4 is fixed to the tool body 1 via a second fixing bolt 7 penetrating the countersunk hole 8 .

[0030] Moreover, the second fixed platen 4 can move axially along the tooling body 1. Among them, the countersunk hole 8 is open at one end away from the limiting groove 2, and the length of the countersunk hole 8 along the axial direction of the tooling body 1 is greater than the maximum outer diameter of the second fixing bolt 7, so that the axial movement of the first fixed platen 3 can be achieved by changing the fixed position of the second fixing bolt 7 in the countersunk hole 8. When fixing the original rod 100 of the anvil seat, move the second fixed platen 4 in the direction close to the original rod 100 of the anvil seat until it abuts against the end of the original rod, and then lock the second fixing bolt 7. At this time, the second fixed platen 4 cooperates with the first fixed platen 3 to fix the original rod 100 of the anvil seat; when the cutting is completed and the anvil seat blank 200 is obtained, loosen the second fixing bolt 7, move the second fixed platen 4 in the direction away from the original rod 100 of the anvil seat, loosen the anvil seat blank 200, and the material can be taken out, which is convenient to operate.

[0031] In addition, if Figure 3 As shown, the first fixed platen 3 and the second fixed platen 4 are respectively provided with a first notch 10 and a second notch 11 at one end facing the limiting groove 2, and the first notch 10 and the second notch 11 are used to position the two ends of the anvil original bar 100. Preferably, the heights of the first notch 10 and the second notch 11 are adapted to the size of the anvil original bar 100. When the first fixed platen 3 and the second fixed platen 4 fix the two ends of the anvil original bar 100, the two ends of the anvil original bar 100 enter the first notch 10 and the second notch 11 respectively, and the first notch 10 and the second notch 11 limit the up and down movement of the anvil original bar 100.

[0032] Furthermore, combined Figure 2-3 The tool body 1 is also provided with a third fixed platen 5, which is located in the middle of the first fixed platen 3 and the second fixed platen 4. The third fixed platen 5 is fixed to the tool body 1 by a third fixing bolt 9.

[0033] The original rod 100 of the anvil needs to be cut twice, the first cutting is from the middle of the original rod to both ends, and then the second cutting is done, the second cutting is done at both ends of the original rod. The third fixed pressing plate 5 is used to fix the original rod 100 of the anvil after the first cutting.

[0034] After the first wire cutting, two intermediate cutting surfaces are formed in the middle of the original bar, and a wire cutting space is formed between the two intermediate cutting surfaces. The third fixed pressing plate 5 passes through the wire cutting space to fix the original bar. Preferably, the thickness of the third fixed pressing plate 5 is not greater than the vertical height of the two intermediate cutting surfaces on the two anvil blanks 200 when they are placed facing each other.

[0035] Based on the fixation of the original bar material after the first wire cutting by the third fixed pressing plate 5, the stable operation of the second wire cutting can be guaranteed.

[0036] In order to fix the whole tool, one end of the tool body 1 facing away from the limit slot 2 extends downward to form a mounting plate 12, and a mounting hole is provided on the mounting plate 12. During installation, the whole tool is fixed on the working surface of the wire cutting machine by bolts passing through the mounting holes, and wire cutting can be performed.

[0037] The specific implementation principle of the utility model is:

[0038] First, fix the tool body 1 on the online cutting machine according to the site requirements;

[0039] Next, clamp the bar material: take 8 anvil base original bar materials 100, clamp them on the 8 limit slots 2 respectively, and fix the ends of each original bar material by the first fixed pressure plate 3 and the second fixed pressure plate 4. Figure 4 ;

[0040] Next, the original rod material 100 of the anvil is cut as required, completing the first wire cutting;

[0041] Afterwards, the third fixed pressing plate 5 is clamped to fix the bar after the first wire cutting;

[0042] After that, cut the original rod of the nail holder again according to the requirements 100, and complete the second wire cutting. Figure 5 ;

[0043] Finally, release the first fixed platen 3 and the second fixed platen 4, pull the second fixed platen 4 apart, remove the third fixed platen 5, take out the workpiece, and one cutting is completed, after which the bar can be clamped and processed.

[0044] The tooling of this embodiment can not only complete the cutting of 8 anvil seat original bars 100 at one time, but also produce two anvil seat blanks 200 for each bar.

[0045] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
