Description

Technical Field

[0001] This utility model relates to the field of forming tool technology, specifically an integrated forming tool with a milling groove and chamfering composite cutting edge. Background Technology

[0002] Forming tools are special tools designed and manufactured according to the specific geometric shape and size requirements of the workpiece. The shape of their cutting edge is consistent with the contour or cross-sectional shape of the workpiece being machined. They can directly form a specific structure in one machining operation. During the machining process, the tool is mounted on the machine tool spindle through the tool holder. The spindle drives the tool to rotate at high speed. They are widely used in machining, mold manufacturing, aerospace and other fields.

[0003] An existing patent (publication number: CN215845940U) discloses an end mill with a chamfering function. The cutter body consists of a finish milling section, a chamfering section, a chip removal section, and a clearance section, arranged sequentially from the top. Chip removal grooves are provided in the finish milling section, chamfering section, and chip removal section, spiraling through the front end. These grooves intersect with the cutter body to form a finish milling cutting edge in the finish milling section and a chamfering cutting edge in the chamfering and chip removal sections. There are four chip removal grooves, which divide both the finish milling cutting edge and the chamfering cutting edge into four teeth.

[0004] In the field of forming tools, existing technologies use components such as milling sections and chamfering sections to enable tools to achieve multiple effects such as milling grooves and chamfering. However, in actual use, the depth of some milling grooves is not uniform, and the setting of the chamfering section is relatively fixed and cannot be adjusted according to the depth. Only tools of the corresponding length can be replaced, resulting in a limited overall effect and poor applicability. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technologies have limitations in their overall performance and applicability, the depth of some milling grooves is not uniform, and the setting of the chamfer section is relatively fixed and cannot be adjusted according to the depth. The only solution is to replace the tool with the corresponding length.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An integrated forming tool with a milling and chamfering composite cutting edge, characterized in that it comprises:

[0009] A tool holder, wherein a receiving rod is fixedly installed at the top end of the tool holder and a milling cutter is fixedly installed at the bottom end of the tool holder, and a limit groove is formed on the outer wall of the tool holder, and an adjustment mechanism is provided inside the limit groove;

[0010] The adjustment mechanism includes a sliding ring, which is slidably connected to the outer wall of the tool holder. A limit block is fixedly installed at the bottom end of the sliding ring, and a connecting block is fixedly installed at the bottom end of the limit block. A chamfer is fixedly installed at the bottom end of the connecting block.

[0011] As a further embodiment of this utility model: a retaining ring is fixedly installed on the outer wall of the sliding ring, and a rotating ring is sleeved on the outside of the retaining ring, and a retaining groove is opened on the inner wall of the rotating ring corresponding to the position of the retaining ring.

[0012] As a further improvement of this utility model: a reinforcing block is fixedly installed on the outer wall of the limiting block, and a sleeve hole is opened inside the connecting block.

[0013] As a further embodiment of this utility model: the sliding ring and the tool holder form a sliding structure, and the tool holder and the chamfered part form a sliding structure.

[0014] As a further improvement of this utility model: the limiting block extends through the interior of the limiting groove, and the limiting groove and the reinforcing block form a sliding structure.

[0015] As a further improvement of this utility model: the top end of the rotating ring is provided with a connecting hole, and a reinforcing mechanism is provided inside the connecting hole.

[0016] As a further embodiment of this utility model: the reinforcing mechanism includes a sliding block, the sliding block protruding from the interior of the connecting hole, and a connecting ring is fixedly installed on the outer wall of one end of the sliding block at the connecting hole.

[0017] As a further improvement of this utility model: an insertion hole is provided inside the connecting ring at the position corresponding to the sliding block, and a connecting groove is provided inside the connecting hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model, through the design of a sliding ring, a limiting block, a connecting block, a retaining ring, a rotating ring, and a reinforcing block, enables rapid position adjustment of the chamfered part. It can be adjusted according to the depth of the milling groove, improving the overall applicability of the tool. At the same time, the limiting block and the reinforcing block engage inside the limiting groove, which can improve the torque bearing capacity of the tool during rotation.

[0020] This invention, through the design of a sliding block, a connecting ring, an insertion hole, and a connecting groove, enables the sliding block to fill the interior of the limiting groove during the adjustment of the rotating ring, forming a locking effect and minimizing the presence of too many gaps in the limiting groove, thereby maintaining the strength of the cutting tool.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0030] Please see Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides an integrated forming tool with a milling groove and chamfering composite cutting edge, including: a tool bar 1, a receiving rod 2 fixedly installed at the top of the tool bar 1, a milling cutter part 3 fixedly installed at the bottom of the tool bar 1, a limiting groove 4 opened on the outer wall of the tool bar 1, and an adjustment mechanism 5 provided inside the limiting groove 4;

[0031] The adjusting mechanism 5 includes a sliding ring 501, which is slidably connected to the outer wall of the tool bar 1. A limit block 502 is fixedly installed at the bottom end of the sliding ring 501, and a connecting block 503 is fixedly installed at the bottom end of the limit block 502. A chamfered part 504 is fixedly installed at the bottom end of the connecting block 503.

[0032] Specifically, a retaining ring 505 is fixedly installed on the outer wall of the sliding ring 501, and a rotating ring 506 is sleeved on the outside of the retaining ring 505. A retaining groove 507 is opened on the inner wall of the rotating ring 506 corresponding to the position of the retaining ring 505.

[0033] Furthermore, through the cooperation of the retaining ring 505 and the retaining groove 507, when the rotating ring 506 rotates, the sliding ring 501 remains stable under the limit of the limiting groove 4 and the limiting block 502, and does not rotate with the rotation of the rotating ring 506.

[0034] Specifically, a reinforcing block 508 is fixedly installed on the outer wall of the limiting block 502, and a sleeve hole 509 is opened inside the connecting block 503.

[0035] Furthermore, the reinforcing block 508 can increase the support of the limiting block 502 on the chamfered part 504, and the engagement of the reinforcing block 508 with the limiting groove 4 further improves the load-bearing capacity of the entire tool during torque rotation.

[0036] Specifically, the sliding ring 501 and the tool holder 1 form a sliding structure, and the tool holder 1 and the chamfered part 504 form a sliding structure.

[0037] Furthermore, by sliding the sliding ring 501, the chamfered part 504 can be adjusted via the limit block 502, and the position can be adjusted according to the depth of the milling cutter slot, thereby improving the overall applicability and flexibility.

[0038] Specifically, the limiting block 502 extends into the interior of the limiting groove 4, and the limiting groove 4 and the reinforcing block 508 form a sliding structure.

[0039] Furthermore, through the cooperation of the limiting block 502 and the reinforcing block 508, and the sliding engagement of the limiting groove 4 with the tool holder 1, the chamfered part 504 can be adjusted while maintaining the torque bearing capacity during the turning process.

[0040] In use, the tool holder 1, the receiving rod 2, and the milling cutter part 3 are integral and fixed by the receiving rod 2 and the machine tool fixture. The limiting block 502 fixed by the sliding ring 501 is slidably connected by passing through the limiting groove 4. The sliding ring 501 is rotatably connected to the groove 507 of the rotating ring 506 through the retaining ring 505. The rotating ring 506 is threadedly connected to the tool holder 1. Thus, the position of the sliding ring 501 is adjusted by adjusting the position of the rotating ring 506, so that the limiting block 502 drives the connecting block 503. The connecting block 503 and the chamfered part 504 are adjusted in position along the tool holder 1 and the milling cutter part 3 through the sleeve hole 509. The adjustment is made according to the depth of the milling cutter hole groove. The reinforcing block 508 is completely matched with the limiting groove 4 to avoid gaps that may cause loosening or shaking during the turning process.

[0041] In summary, by simply adjusting the rotation of the rotating ring 506, the position of the chamfered part 504 can be adjusted according to the depth of the milling cutter slot, making the entire tool a unified whole that can be adjusted. This makes it suitable for machining slots of different depths, improving overall applicability and flexibility. It avoids the inconvenience of having to change the corresponding tool when encountering slots of different depths. At the same time, the engagement of the limiting groove 4 with the limiting block 502 and the reinforcing block 508 can prevent the rotating ring 506 from loosening or disengaging during the turning process. Example 2

[0042] Please see Figure 1 , Figure 3 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for an integrated forming tool with a milling groove and chamfering composite cutting edge.

[0043] Specifically, the top of the rotating ring 506 is provided with a connecting hole 6, and a reinforcing mechanism 7 is provided inside the connecting hole 6.

[0044] Furthermore, the inner diameter of the connecting hole 6 matches the outer diameter of the tool holder 1, and they are connected by threads to each other, making it convenient to adjust the position of the rotating ring 506.

[0045] Specifically, the reinforcing mechanism 7 includes a sliding block 701, which extends through the interior of the connecting hole 6. A connecting ring 702 is fixedly installed on the outer wall of one end of the sliding block 701 in the connecting hole 6.

[0046] Furthermore, by inserting the sliding block 701 into the limiting groove 4, it can fill the relatively empty space inside the tool holder 1, thereby maintaining the overall load-bearing capacity of the tool holder 1.

[0047] Specifically, the connecting ring 702 has an insertion hole 703 at the position corresponding to the sliding block 701, and the connecting hole 6 has a connecting groove 704 inside.

[0048] Furthermore, the insertion hole 703 of the connecting ring 702 is on the same plane as the connection hole 6 without thread. The insertion hole 703 has no thread texture. When the connection hole 6 has thread texture, it protrudes from the connection hole 6 so that it can be threadedly connected with the tool holder 1. The upper part of the connecting groove 704 inside the connection hole 6 has no thread texture to avoid the thread texture from being limited by the sliding block 701, which would prevent the threaded connection with the tool holder 1 and affect the rotation adjustment.

[0049] In use, the connecting ring 702 is rotated through the connecting groove 704 inside the connecting hole 6. The sliding block 701 fixed by the connecting ring 702 passes into the limiting groove 4 and matches the size, which can improve the filling effect of the limiting groove 4 and improve the torque strength during the tool turning process. The connecting ring 702 is used to slide on the outside of the tool holder 1 through the insertion hole 703.

[0050] In summary, by having the sliding block 701 located inside the limiting groove 4, the limiting groove 4 is filled inside the tool holder 1. Since the depth of the milling hole itself is not significantly different, ranging from a few millimeters to a few centimeters, the torque bearing capacity of the tool during the turning process can be maintained, thus preventing the tool holder 1 from breaking due to stress in the through hole.
