Description

Technical Field

[0001] The utility model relates to the technical field of forming boring cutters, in particular to a discarded forming cutter. Background Art

[0002] The forming boring tool is generally composed of a cutting head and a blade for installation. It is a type of hole processing tool. The most common occasion is to install it on an automated CNC lathe to perform inner hole processing, hole expansion, profiling, etc. on metal workpieces.

[0003] However, the working cutter head and the mounting cutter body of the current forming boring tool are integrated. When the cutter head is damaged, the entire boring tool can no longer be used for operation, which wastes the use cost of the boring tool.

[0004] Based on this, the utility model designs a discard type forming knife to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a disposable forming knife to solve the above technical problems.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disposable forming knife, comprising: a knife seat; a slot is provided at one end of the knife seat, a blade is inserted in the slot of the knife seat, a mounting screw is threadedly connected between the blade and the knife seat, two symmetrical auxiliary blocks are fixedly connected to the outer wall of the mounting thread, a threaded rod is threadedly connected to one end of the auxiliary block, an insertion rod is fixedly connected to one end of the threaded rod, a slot is provided on the outer wall of the blade, and one end of the insertion rod is inserted into the slot of the blade.

[0007] Preferably, one end of the threaded rod away from the insertion rod is fixedly connected with a screw plate.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the knife seat and the blade are split, the blade is inserted into the slot of the knife seat for installation, and the blade and the knife seat are fixed together by mounting screws. When the blade is damaged, the mounting screws can be removed, and only the blade needs to be replaced, which saves the use cost;

[0009] After the mounting screw is installed and used, the threaded rod can be rotated using a screw plate to insert the insertion rod at one end of the threaded rod into the slot provided by the blade, thereby reducing the risk of the mounting screw being rotated and loosened.

[0014] In the accompanying drawings, the components represented by the reference numerals are listed as follows:

[0015] 1. Knife holder; 2. Blade; 3. Mounting screws; 4. Auxiliary block; 5. Threaded rod; 6. Insert rod; 7. Tightening plate. DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: a disposable forming knife, comprising: a knife seat 1; a slot is provided at one end of the knife seat 1, a blade 2 is inserted into the slot of the knife seat 1, a mounting screw 3 is threadedly connected between the blade 2 and the knife seat 1, two symmetrical auxiliary blocks 4 are fixedly connected to the outer wall of the mounting thread, a threaded rod 5 is threadedly connected to one end of the auxiliary block 4, an insertion rod 6 is fixedly connected to one end of the threaded rod 5, a slot is provided on the outer wall of the blade 2, and one end of the insertion rod 6 is inserted into the slot of the blade 2;

[0018] The slot of the tool holder 1 and the blade 2 are of matching anisotropic shapes. They are not easy to rotate after being engaged with each other. They are fixed in use by the mounting screws 3. When the blade 2 is damaged, the mounting screws 3 can be removed to replace only the blade 2 of the tool holder 1, saving the cost of use. The threaded rods 5 of the two auxiliary blocks 4 control the insertion rod 6 to be inserted into the slot of the blade 2, to assist in limiting the mounting screws 3 and reduce the risk of its loosening.

[0019] Preferably, one end of the threaded rod 5 away from the insertion rod 6 is fixedly connected with a screw plate 7;

[0020] The screw plate 7 is used to conveniently control the rotation of the threaded rod 5 so that the inserting rod 6 at one end of the threaded rod 5 can be inserted into the slot of the blade 2 .

[0021] A specific application of this embodiment is: the knife seat 1 and the blade 2 are split, and the knife seat 1 is used to install the blade 2 through a slot opened at one end thereof. The blade 2 can be inserted into the slot of the knife seat 1, and then the blade 2 and the knife seat 1 are fixed together using the mounting screws 3. After the blade 2 is damaged, the mounting screws 3 can be removed, and only the blade 2 needs to be replaced, which saves the use cost. After the mounting screws 3 are installed and used, the threaded rod 5 can be rotated using the screw plate 7, and the insertion rod 6 at one end of the threaded rod 5 can be inserted into the slot opened in the blade 2, reducing the risk of the mounting screws 3 rotating and loosening.

[0022] In the description of the present invention, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "the other end", "upper", "one side", "top", "inside", "front", "center", "both ends" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
