Description

Technical Field

[0001] The utility model provides a PCD contour forming cutter, which relates to the technical field of cutters. Background Art

[0002] As the manufacturing precision of various parts becomes higher and higher, and the shapes become more and more complex, the application of forming knives is becoming more and more extensive. PCD forming knives can be defined as non-standard complex contour knives. PCD contour forming knives are mainly suitable for automobile, electronics, aerospace and other industries.

[0003] The existing PCD contour cutter can ensure that there are no horizontal lines on the processed surface, and the surface finish is brighter. At the same time, compared with tungsten steel cutters, PCD cutters have stronger wear resistance and impact resistance. After using PCD contour cutters for drilling, it is generally necessary to chamfer the holes to prevent the edges of the holes from being too sharp and residual burrs from scratching people. However, the existing PCD contour cutters generally only have drilling functions, and another tool needs to be used for additional chamfering after drilling, which is more troublesome.

[0004] Therefore, it is necessary to provide a PCD contour forming tool with chamfering function. Utility Model Content

[0005] In order to overcome the disadvantage of the existing PCD contour cutter that another tool needs to be used for chamfering after drilling, which is relatively troublesome, the utility model provides a PCD contour forming cutter with a chamfering function.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solutions: a PCD contour forming tool, including a main rod, a mounting block, a connecting column, a scraper column and a blade, the main rod is equipped with a mounting block, the mounting block is equipped with a connecting column, the connecting column is equipped with a scraper column, and a plurality of blades are equipped on the scraper column. It also includes a chamfering table and a protrusion, a plurality of protrusions are fixed on the chamfering table, a plurality of sliding grooves are provided on the connecting column, the chamfering table slides in the sliding groove of the connecting column through the protrusion, and a plurality of forming grooves are provided on the chamfering table.

[0007] In one embodiment, a plurality of through holes are formed on the chamfering platform.

[0008] In one embodiment, a plurality of first chip removal grooves are formed on the connecting column.

[0009] In one embodiment, a plurality of second chip removal grooves are formed on the scraper column.

[0010] In one embodiment, the first chip removal groove and the second chip removal groove are both inclined.

[0011] In one embodiment, a pointed cone head is mounted on the scraper column.

[0012] Compared with the prior art, the PCD contour forming knife provided by the embodiment of the utility model has the following advantages:

[0013] 1. Drill the workpiece with the blade on the scraper column, and then chamfer the edge of the drilled hole through the forming groove of the chamfering table. The workpiece debris scraped off by chamfering is discharged backward through the through hole to achieve the effect of chamfering the edge of the workpiece hole.

[0014] 2. Use a pointed cone head to pre-drill a hole for the workpiece to avoid displacement of the tool or workpiece during drilling.

[0015] 3. The chips are guided out from the formed holes through the second chip groove and the first chip groove to achieve the chip removal effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0022] Example 1: A PCD contour forming tool, see Figure 1-Figure 4 As shown, it includes a main rod 1, a mounting block 2, a connecting column 3, a scraper column 4 and a blade 5. The mounting block 2 is installed on the top of the main rod 1 by welding, the connecting column 3 is installed on the mounting block 2 by welding, the scraper column 4 is installed on the connecting column 3 by welding, and four blades 5 for opening holes in the workpiece are installed on the side of the scraper column 4 by welding. It also includes a chamfering platform 6 and a protrusion 601. Four protrusions 601 are fixedly connected to the middle of the chamfering platform 6 by welding. Four sliding grooves 602 are circumferentially opened on the connecting column 3. The chamfering platform 6 slides in the sliding groove 602 of the connecting column 3 through the protrusion 601, and the chamfering platform 6 is opened with eight forming grooves 603 for chamfering.

[0023] When drilling, the main rod 1 drives the connecting column 3 to rotate through the mounting block 2, and then the connecting column 3 drives the scraper column 4 to rotate, and the main rod 1 is lowered, so that the blade 5 on the scraper column 4 drills the workpiece. After the drilling is completed, the main rod 1 continues to descend, and the edge of the drilled hole is chamfered through the forming groove 603 of the chamfering table 6, and the workpiece debris scraped off by the chamfering is discharged backwards through the through hole 604.

[0024] Example 2: Based on Example 1, refer to Figure 2-Figure 4 As shown, the connecting column 3 is circumferentially provided with four first chip grooves 301, and the scraper column 4 is circumferentially provided with four second chip grooves 401. Both the first chip grooves 301 and the second chip grooves 401 are inclined to facilitate pushing the chips out of the first chip grooves 301 and the second chip grooves 401 when the tool rotates. Eight through holes 604 are provided on the chamfering table 6, and a pointed cone head 7 is installed on the top of the scraper column 4 by welding.

[0025] When drilling a workpiece, the pointed cone head 7 can pre-drill a hole for the workpiece and avoid displacement of the tool or the workpiece during drilling. The chips scraped off by the blade 5 are pushed toward the side of the connecting column 3 through the second chip groove 401 on the scraper column 4, and then pushed toward the side of the main rod 1 through the first chip groove 301 on the connecting column 3, so that the chips are pushed out of the formed hole.
