During processing, the tool makes a simple linear feed motion relative to the workpiece, and the shaped surface can be cut out in one cutting stroke. It is simple to operate and has high production efficiency.

[0003] In existing technologies, such as the forming cutter disclosed in CN218395962U, when machining grooves on a workpiece using this new forming cutter, the cutting edge of the new forming cutter faces the machining surface of the workpiece and cuts the groove on the machining surface. Therefore, when machining grooves on a workpiece using this new forming cutter, the appropriate insert can be selected according to the width of the groove, making machining simple and convenient, effectively solving the problem of difficult machining of complex grooves; it can ensure the surface finish of the machining edge, improve machining accuracy and quality, and thus improve the surface quality and service life of the workpiece.

[0004] However, in implementing the relevant technology, the following problems were found in the above-mentioned forming knife design: In the prior art, the processing accuracy and quality can be improved by setting components such as blades. However, in actual use, the tool is directly connected and locked to the machine tool. When dealing with materials of different thicknesses or specifications, it is troublesome for the operator to adjust the processing depth, which affects work efficiency. Therefore, an adjustable depth forming knife is provided to overcome the above defects. Utility Model Content

[0005] This invention addresses the problem that when cutting tools are directly connected and locked to machine tools, it is inconvenient to disassemble and assemble them when adjusting the processing depth for materials of different thicknesses or specifications, which affects work efficiency. Therefore, this invention provides an adjustable-depth forming tool.

[0006] The present invention achieves the above objectives through the following technical solution: an adjustable depth forming knife, including a connecting sleeve, a through rod extending from the inside of the connecting sleeve, and an abutment block fixedly installed at the bottom end of the through rod, and a cutting head fixedly installed at the bottom end of the abutment block, and an adjustment mechanism provided on the outer wall of the connecting sleeve.

[0007] The adjustment mechanism includes a mounting groove, which is formed on the outer wall of the connecting sleeve. A rotating hole is formed inside the mounting groove, and a rotating rod extends through the rotating hole. A rotating plate is rotatably connected to the outer wall of one end of the rotating rod that extends through the rotating hole.

[0008] As a further improvement of this utility model: a limiting block is fixedly installed on the end of the rotating plate facing the protruding rod, and a corresponding hole is opened inside the lower part of the placement groove at the position of the limiting block.

[0009] As a further improvement of this utility model: a limiting hole is provided on the outer wall of the protruding rod, and a fixing collar is slidably connected to one side of the mounting groove on the outer wall of the connecting sleeve.

[0010] As a further embodiment of this utility model: a contacting mechanism is provided on one side of the fixed collar, the contacting mechanism includes a connecting ring, the connecting ring is fixedly installed at the bottom end of the fixed collar, and a bearing block is fixedly installed on the outer wall of the rotating plate.

[0011] As a further improvement of this utility model: a telescopic rod is fixedly installed on one side of the bottom end of the connecting ring, and a limit ring is fixedly installed below the telescopic rod.

[0012] As a further embodiment of this utility model: a fixing rod is fixedly installed on the other side of the bottom end of the connecting ring, and an adjusting sleeve is sleeved on the lower part of the outer wall of the fixing rod, and a locking block is fixedly installed at the bottom end of the adjusting sleeve.

[0013] As a further embodiment of this utility model: the adjusting sleeve is threadedly connected to the fixed rod, and the adjusting sleeve forms a rotating structure with the limiting ring through the locking block.

[0014] The beneficial effects of this utility model are as follows: First, the rotating plate is rotated in the placement groove through the rotating hole and rotating rod, which allows the through rod to lose its limit and adjust its position according to the depth. After the position is determined, the rotating plate is reset, and the limiting block is inserted into the limiting hole through the corresponding hole to limit it. It is also fitted and pressed against the outer wall of the rotating plate with the fixing ring that is threaded to the connecting sleeve. This can limit the rotating plate and prevent it from loosening. As a result, the depth of the forming knife can be quickly adjusted or the knife head can be replaced, which improves the processing efficiency and avoids the use process being too limited.

[0015] By cooperating with the fixed collar and the connecting ring, the rotating plate is pressed against the bearing block at the same time, which further improves the stability after assembly. The adjusting sleeve is connected to the limiting ring through the locking block, thereby adjusting the length between the adjusting sleeve and the fixed rod, so that the limiting ring slides along the connecting sleeve, thereby improving the comprehensiveness of the limiting force, improving the limiting of the rotating plate, and avoiding loosening or shaking during processing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] like Figures 1 to 5As shown, an adjustable-depth forming cutter includes a connecting sleeve 1, with a protruding rod 2 extending from the inside of the connecting sleeve 1. A contact block 3 is fixedly installed at the bottom end of the protruding rod 2, and a cutter head 4 is fixedly installed at the bottom end of the contact block 3. An adjustment mechanism 5 is provided on the outer wall of the connecting sleeve 1. The adjustment mechanism 5 includes a mounting groove 501, which is located on the outer wall of the connecting sleeve 1. A rotating hole 502 is provided inside the mounting groove 501, and a rotating rod 503 extends through the rotating hole 502. A rotating plate 504 is rotatably connected to the outer wall of one end of the rotating rod 503 extending through the rotating hole 502. A limit block 505 is fixedly installed on the end of the rotating plate 504 facing the protruding rod 2. A corresponding hole 506 is provided at the lower part of the mounting groove 501 corresponding to the position of the limit block 505. A limiting hole 507 is provided on the outer wall of the through rod 2, and a fixing collar 508 is slidably connected to one side of the mounting groove 501 on the outer wall of the connecting sleeve 1. First, the rotating plate 504 is rotated in the mounting groove 501 through the rotating hole 502 and the rotating rod 503, which allows the through rod 2 to lose its limit and adjust its position according to the depth. After the position is determined, the rotating plate 504 is reset, and the limiting block 505 is inserted into the limiting hole 507 through the corresponding hole 506 for limiting. It is also fitted and pressed against the outer wall of the rotating plate 504 with the fixing collar 508 which is threaded to the connecting sleeve 1. This can limit the rotating plate 504 to prevent loosening, thereby enabling quick depth adjustment of the forming cutter or replacement of the cutter head 4, improving processing efficiency while avoiding excessive limitations in the use process. Example 2

[0024] In addition to all the technical features included in Embodiment 1, this embodiment also includes: a contact mechanism 6 is provided on one side of the fixed collar 508, the contact mechanism 6 includes a connecting ring 601, the connecting ring 601 is fixedly installed at the bottom end of the fixed collar 508, a bearing block 602 is fixedly installed on the outer wall of the rotating plate 504, a telescopic rod 603 is fixedly installed on one side of the bottom end of the connecting ring 601, a limit ring 604 is fixedly installed below the telescopic rod 603, a fixed rod 605 is fixedly installed on the other side of the bottom end of the connecting ring 601, an adjusting sleeve 606 is sleeved on the lower part of the outer wall of the fixing rod 605, a locking block 607 is fixedly installed at the bottom end of the adjusting sleeve 606, and the adjusting sleeve... The sleeve 606 is threadedly connected to the fixed rod 605. The adjusting sleeve 606 forms a rotating structure with the limiting ring 604 through the locking block 607. Through the cooperation of the fixed ring 508 and the connecting ring 601, when the rotating plate 504 is pressed, it simultaneously abuts against the bearing block 602, further improving the stability after assembly. The adjusting sleeve 606 is rotatably connected to the limiting ring 604 through the locking block 607, thereby adjusting the length between the adjusting sleeve 606 and the fixed rod 605, so that the limiting ring 604 slides along the connecting sleeve 1, thereby improving the comprehensiveness of the limiting force, improving the limiting of the rotating plate 504, and avoiding loosening or shaking during processing.

[0025] Working principle: The through rod 2, the contact block 3, and the cutter head 4 are integrated into one structure. The connecting sleeve 1 is used for installation and fixation with the machine tool or power end. To the required machining depth, the through rod 2 passes through the connecting sleeve 1, and then rotates through the rotating hole 502 and the rotating rod 503, causing the rotating plate 504 inside the mounting slot 501 to rotate. After the position of the through rod 2 is determined, the rotating plate 504 resets, allowing the limiting block 505 to be inserted through the corresponding hole 506 into the limiting hole 507 to limit the through rod 2. The fixing collar 508 is threadedly connected to the connecting sleeve 1 and the rotating plate 504, covering and fixing the rotating plate 504. This allows for quick assembly / disassembly or depth adjustment. The through rod 2 has a hexagonal cross-section, which can increase the torque force of the connecting sleeve 1 driving the through rod 2 to rotate. At the same time, turning the adjusting sleeve 606 is rotatably connected to the limiting ring 604 via the locking block 607, so that it can slide along the fixed rod 605 to adjust the position of the limiting ring 604 on the rotating plate 504. It also works with the telescopic rod 603 to keep the limiting ring 604 stable, improving the stability of limiting the rotating plate 504. With the engagement position formed by the connecting ring 601 and the fixed sleeve 508, when the fixed sleeve 508 covers the rotating plate 504, it can abut against the bearing block 602, further improving the stability after adjustment and preventing loosening.
