However, with the continuous improvement of machining accuracy and the diversification of machining materials, the requirements for composite forming knives are becoming increasingly stringent. Traditional composite forming knives usually have a fixed cutter head angle, which limits their machining range and flexibility to a certain extent. At present, although there are many types of composite forming knives on the market, the cutter head angle of most knives is fixed and cannot adapt to the changes of different materials and different machining requirements. When the machining angle needs to be changed, the entire tool often needs to be replaced, which not only increases the machining cost, but also reduces the machining efficiency. Because we proposed an adjustable composite forming knife.

DETAILED DESCRIPTION

[0024] 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 in 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.

[0025] See also Figure 1-4 The utility model provides a technical solution: a composite forming knife for CNC machining, comprising a handle 1, a disassembly and assembly mechanism is connected to one side of the handle 1, a block 2 is corresponding to one side of the disassembly and assembly mechanism, two horizontal plates 21 are connected to one side of the block 2, a rotating mechanism is arranged inside the two horizontal plates 21, a fixing mechanism is connected to the top of the rotating mechanism, and a cutter head 4 is connected to one side of the rotating mechanism; when the staff is ready to use the tool, the handle 1 and the block 2 are first installed by the disassembly and assembly mechanism, and then the fixing mechanism is opened, the angle of the cutter head 4 can be adjusted by the rotating mechanism, and then it is fixed by the fixing mechanism. By providing a rotating mechanism, the staff can adjust the angle of the cutter head 4 according to the processing requirements, which improves the flexibility and adaptability of the tool. By providing a fixing mechanism, the tool can be fixed after the angle is adjusted, ensuring stability during work and improving the safety of the tool. By providing a disassembly and assembly mechanism, the tool can be quickly disassembled and assembled, which is convenient for the staff to replace and improves work efficiency.

[0026] The disassembly and assembly mechanism comprises a round rod 11, and the round rod 11 and the handle 1 are connected in rotation. One end of the round rod 11 is connected with a rotating block 12, and the round rod 11, the rotating block 12 and the block 2 correspond to each other; when the staff is ready to disassemble the tool, first rotate the rotating block 12, and the rotating block 12 will move upward and break away from the restriction of the block 2, and then the staff will move the round rod 11 to one side, because the round rod 11 and the handle 1 are connected in rotation, the staff can move the round rod 11 from the vertical direction to the horizontal direction, so that the block 2 is not restricted and can be easily taken down. When installing, the block 2 is placed in the corresponding position, and then the round rod 11 is changed from horizontal to vertical, and then the rotating block 12 is twisted to make the rotating block 12 enter the inside of the block 2 to complete the fixation. By providing the disassembly and assembly mechanism, the device can be easily disassembled, retaining the part of the handle 1, saving costs.

[0027] One end of the round rod 11 is provided with a thread, and the round rod 11 and the rotating block 12 are threadedly connected; because the round rod 11 and the rotating block 12 are threadedly connected, that is, the head is threadedly connected, so by twisting the rotating block 12, the rotating block 12 can be upward or downward under the relationship of the thread, and the direction of rotation can be controlled.

[0028] The block 2 has through grooves 25 on both sides, the round rod 11 is inside the through grooves 25, and a circular groove 26 is formed on one side of the through grooves 25, and the circular grooves 26 correspond to the rotating block 12; when the round rod 11 is in the vertical direction, it is just inside the through grooves 25, and the through grooves 25 are equivalent to a containing space. When the round rod 11 is in a fixed state, the rotating block 12 is partially screwed into the circular grooves 26 when it is twisted, so that the circular grooves 26 block the rotating block 12 and limit the movement of the round rod 11. When it needs to be disassembled, the rotating block 12 can be screwed out of the circular grooves 26.

[0029] The rotating mechanism includes a vertical rod 3, which passes through two horizontal plates 21 and is slidably connected to the two horizontal plates 21. Two single tooth blocks 23 are sleeved on the outer side of the vertical rod 3. The single tooth blocks 23 are fixedly connected to the horizontal plates 21. The outer side of the vertical rod 3 is connected with a double tooth block 24. The single tooth block 23 corresponds to the double tooth block 24. The double tooth block 24 is fixedly connected to the cutter head 4. The vertical rod 3 is connected to the fixing mechanism. A spring 22 is fixedly connected in the middle of the two horizontal plates 21. When the staff needs to adjust the angle of the cutter head 4, the fixing mechanism is first opened, that is, the fixing mechanism does not restrict the two horizontal plates 21. When it is originally fixed, the middle of the two horizontal plates 21 The spring 22 is in a compressed state. Now that there is no restriction, the rebound force of the spring 22 pushes the two horizontal plates 21 outward. The two horizontal plates 21 and the block 2 are connected by rotation. When the spring 22 pushes outward, both ends have force, so that the two horizontal plates 21 are in an open state, and the originally meshed double tooth block 24 and the single tooth block 23 are separated. The two single tooth blocks 23 are away from the double tooth block 24, so that the middle double tooth block 24 can rotate freely, so that the angle of the cutter head 4 can be adjusted. After the adjustment is completed, the two horizontal plates 21 are pressed down by the fixing mechanism, so that the single tooth block 23 and the double tooth block 24 can bite together again. By providing a rotating mechanism, the angle of the cutter head 4 is easy to adjust, which can adapt to different work requirements and improve the flexibility of work.

[0030] The two single tooth blocks 23 are in opposite directions, and a round block is fixedly connected to the bottom of the vertical rod 3, which is located on the outside of the horizontal plate 21. The double tooth block 24 and the vertical rod 3 are connected in a sliding manner. The two single tooth blocks 23 must be engaged with the double tooth block 24, so that the double-sided engagement is more stable, so they are in opposite positions. The round block at the bottom prevents the horizontal plate 21 from sliding out of the vertical rod 3. The double tooth block 24 and the vertical rod 3 are connected in a sliding manner, and the double tooth block 24 can rotate around the vertical rod 3. In this way, when the horizontal plate 21 is opened, the vertical rod 3 will slide inside the double tooth block 24, and when adjusting the angle, the double tooth block 24 can rotate again.

[0031] The fixing mechanism includes a short rod 32, and the short rod 32 and the vertical rod 3 are connected in rotation. Two circular blocks 31 are fixedly connected to the outside of the short rod 32, and a push plate 33 is fixedly connected to the outside of the two circular blocks 31. As can be seen from the figure, the short rod 32 is in an eccentric position of the circular block 31. Such a circular block 31 is equivalent to a cam. When the staff pushes the push plate 33 downward, the circular block 31 rotates, and a large area of ​​the circular block 31 moves downward, that is, the right side part moves downward, and the horizontal plate 21 is pressed downward. The lower horizontal plate 21 is against the circular block, so that the two tooth blocks are engaged. By providing a fixing mechanism, the tool can be fixed after the angle is adjusted, ensuring safety during operation.

[0032] The internal thread of the push plate 33 is connected with a bolt 34, and a circular hole 27 is opened inside the cross plate 21, and the bolt 34 corresponds to the circular hole 27; when the push plate 33 is pressed to the bottom, the bolt 34 is just opposite to the circular hole 27, and the bolt 34 is screwed into the interior of the circular hole 27 to complete the fixation.

[0033] The inside of the circular hole 27 is provided with a thread, and the circular hole 27 and the bolt 34 are threadedly connected; by utilizing the threaded connection between them, the bolt 34 and the circular hole 27 can be tightly fixed, and they can be separated by twisting the bolt 34.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
