Quick-locking forming T-shaped cutter

Abstract

This utility model belongs to the field of cutting tool technology, and particularly relates to a T-blade with quick-locking forming. Addressing the problem of cumbersome disassembly and assembly in existing designs, the following solution is proposed: A blade holder with a blade protruding from its bottom end and a fastening mechanism externally mounted on the blade holder. The fastening mechanism has a sliding groove on the outside of the blade holder, and an insertion groove is formed below the external sliding groove. A limiting block is fixedly installed at one end of the blade that inserts into the blade holder. A sliding plate is slidably connected inside the sliding groove. After the blade is inserted into the blade holder through the insertion groove, it is engaged by the limiting block. Then, rotating the connecting ring causes the sliding plate, connected to the blade, to slide along the sliding groove via the locking groove and the locking block. This allows the pressure plate to press against the limiting block, and the insertion block to be inserted into the positioning hole for limiting, preventing loosening. This allows for quick assembly and locking of the blade holder and blade, facilitating the replacement of different blades or replacement after damage.

Description

Technical Field

[0001] This utility model relates to a forming T-blade, specifically a blade quick-lock forming T-blade, belonging to the field of forming tool technology. Background Technology

[0002] A forming T-cutting tool is a tool used to machine specific shapes. It is typically made of high-performance tool materials such as cemented carbide or high-speed steel. Carbide forming T-cutting tools have higher hardness, wear resistance, and heat resistance, making them suitable for machining high-hardness materials or applications requiring high machining precision. High-speed steel forming T-cutting tools, on the other hand, have better toughness and can withstand certain impact loads, often used for machining materials with relatively lower hardness.

[0003] In the prior art, such as the multi-blade spiral forming T-shaped cutter disclosed in announcement number CN217832022U, this utility model designs nine cutting edges, which reduces the machining resistance of the cutting edges and thus improves the service life of the tool. In addition, the two ends of the chip removal groove extend to the two end faces of the cutting part, which can smoothly divert the waste chips into the chip removal groove and quickly discharge them from the bottom of the cutting part, avoiding the excessive temperature and tool breakage caused by the accumulation of waste chips, and extending the service life of the tool.

[0004] However, in implementing the relevant technology, the following problems were found in the multi-blade spiral forming T-cutting tool designed above: In the prior art, the tool life is improved by the design of the cutting edge, but in the actual use process, since the tool is fixed before processing, it is more troublesome to disassemble and assemble when the blade needs to be changed to a different shape or when it is worn and needs to be replaced. In view of this, a blade quick-locking forming T-cutting tool is provided to overcome the above defects. Utility Model Content

[0005] This utility model provides a T-blade for quick-locking and forming of blades to solve the technical problem that processing is carried out after the above-mentioned cutting tools are fixed, and the disassembly and assembly are relatively troublesome when the blades need to be changed to different shapes or when they are worn and need to be replaced.

[0006] The present invention achieves the above objectives through the following technical solution: a blade quick-locking forming T-blade, including a blade bar, a blade protruding from the bottom end of the blade bar, and a fastening mechanism provided on the outside of the blade bar;

[0007] The fastening mechanism has a sliding groove on the outside of the tool holder, and a through groove is provided below the sliding groove on the outside of the tool holder. A limit block is fixedly installed at one end of the blade that passes through the tool holder. A sliding plate is slidably connected inside the sliding groove, and a pressure plate is fixedly installed on one side of the sliding plate. A connecting ring is slidably connected above the sliding groove on the outside of the tool holder.

[0008] As a further improvement of this utility model: a slot is provided inside the connecting ring, and a block is fixedly installed on the outer wall of the sliding plate at the position corresponding to the slot.

[0009] As a further improvement of this utility model: the connecting ring is threadedly connected to the tool bar, and the connecting ring forms a rotating structure between the slot and the block.

[0010] As a further improvement of this utility model: an insertion block is fixedly installed at the bottom end of the pressure plate, and a positioning hole is provided at the top end of the limiting block.

[0011] As a further improvement of this utility model: a limiting mechanism is provided on one side of the slide groove. The limiting mechanism includes a placement groove, which is opened on one side of the slide groove outside the tool holder. A positioning block is slidably connected inside the placement groove, and a fixing ring is fixedly installed on one side of the positioning block.

[0012] As a further improvement of this utility model: a mounting hole is provided on one side of the inside of the insertion groove, and a connecting rod is fixedly installed at the bottom of the slide plate corresponding to the mounting hole.

[0013] As a further improvement of this utility model: the fixing ring is welded to the sliding plate, and the fixing ring forms a sliding structure with the sliding groove through the positioning block.

[0014] The beneficial effects of this utility model are: after the blade is inserted into the blade bar through the insertion groove, it is locked by the limiting block. Then, the connecting ring is rotated, and the sliding plate connected by the rotating ring slides along the groove through the slot and the locking block, so that the pressure plate presses the limiting block and the insertion block is inserted into the positioning hole for limiting, thus avoiding loosening. It can quickly assemble and lock the blade bar and the blade, and facilitate the replacement of different blades or replacement after damage.

[0015] The stability of the slide plate is improved by inserting the connecting rod into the mounting hole to prevent loosening. At the same time, the fixing ring follows the movement of the slide plate, allowing the positioning block to slide along the mounting groove, further improving the stability of the slide plate and increasing the torque bearing capacity of the blade holder on the blade during blade rotation.

[0021] 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

[0022] like Figs. 1 to 4 As shown, a blade quick-locking forming T-blade includes a blade shank 1, with a blade 2 protruding from the bottom end of the blade shank 1, and a fastening mechanism 3 is provided on the outside of the blade shank 1;

[0023] The fastening mechanism 3 has a sliding groove 301 on the outside of the tool holder 1, and a through groove 302 is formed below the sliding groove 301 on the outside of the tool holder 1. A limit block 303 is fixedly installed at one end of the blade 2 that passes through the tool holder 1. A sliding plate 304 is slidably connected inside the sliding groove 301, and a pressure plate 305 is fixedly installed on one side of the sliding plate 304. A connecting ring 306 is slidably connected above the sliding groove 301 on the outside of the tool holder 1. A retaining groove 307 is formed inside the connecting ring 306. A retaining block 308 is fixedly installed on the outer wall of the sliding plate 304 at the position corresponding to the retaining groove 307. The connecting ring 306 is threadedly connected to the tool holder 1, and the connecting ring 306 is threadedly connected to the tool holder 1. The connecting ring 306 forms a rotating structure with the locking block 308 through the locking groove 307. The bottom end of the pressure plate 305 is fixedly installed with the insertion block 4, and the top end of the limiting block 303 is provided with the positioning hole 5. After the blade 2 is inserted into the blade rod 1 through the insertion groove 302, it is locked by the limiting block 303. Then, the connecting ring 306 is rotated, and the sliding plate 304 connected by the rotating ring slides along the sliding groove 301 through the locking groove 307 and the locking block 308, so that the pressure plate 305 presses the limiting block 303 and the insertion block 4 passes through the positioning hole 5 for limiting, so as to prevent loosening. It can quickly assemble and lock the blade rod 1 and the blade 2, which is convenient for replacing different blades 2 or replacing them after damage. Example 2

[0024] In addition to all the technical features included in Embodiment 1, this embodiment also includes: a limiting mechanism 6 is provided on one side of the slide groove 301, the limiting mechanism 6 includes a placement groove 601, the placement groove 601 is opened on one side of the external slide groove 301 of the tool holder 1, and a positioning block 602 is slidably connected inside the placement groove 601, a fixing ring 603 is fixedly installed on one side of the positioning block 602, and a placement hole 604 is opened on one side of the inside of the insertion groove 302, the bottom end of the slide plate 304 corresponding to the placement hole 604. A connecting rod 605 is fixedly installed in a position. The fixing ring 603 is welded to the slide plate 304, and the fixing ring 603 forms a sliding structure with the slide groove 301 through the positioning block 602. The connecting rod 605 is inserted into the mounting hole 604 to improve the stability of the slide plate 304 and prevent it from loosening. At the same time, the fixing ring 603 follows the movement of the slide plate 304, allowing the positioning block 602 to slide along the mounting groove 601, further improving the stability of the slide plate 304 and increasing the torque bearing capacity of the blade shank 1 on the blade 2 during the rotation of the blade 2.

[0025] Working principle: The blade 2 and the limiting block 303 are integrated and pass through the insertion groove 302 into the blade bar 1. Then, the connecting ring 306, which is threaded to the blade bar 1, is rotated and connected to the locking block 308 through the locking groove 307. This causes the sliding plate 304 to slide along the sliding groove 301, allowing the pressure plate 305 to press against the limiting block 303. The insertion block 4 is inserted into the positioning hole 5 to prevent the blade 2 and the limiting block 303 from rotating during the rotation process. At the same time, the connecting rod 605 passes through the placement hole 604 to further improve the stability after fixing. This allows the blade 2 and the blade bar 1 to be quickly assembled and locked. The sliding plate 304 is fixed to the fixing ring 603. As the fixing ring 603 moves with the sliding plate 304, it slides along the placement groove 601 through the positioning block 602, allowing the sliding plate 304 to slide stably and improving the stability of the sliding plate 304 driving the pressure plate 305 to press against the limiting block 303.
