Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically to a metal can manufacturing tool. Background Technology

[0002] In the current technology for processing metal cans, a cutting machine is conventionally used to cut the sheet metal for can making to a certain size;

[0003] The cutting operation of existing cutting machines mainly relies on the cooperation between a circular saw blade and a motor. The circular saw blade is installed on the output shaft of the motor, and when the motor is turned on, the circular saw blade rotates at high speed to cut the workpiece material.

[0004] However, when installing a circular saw, it is often necessary to ensure that the orientation of the saw blade head corresponds to the opposite direction of the motor output shaft rotation. If the circular saw blade is installed backwards, so that the orientation of the saw blade head is opposite to the direction of the motor output shaft rotation, the circular saw will not be able to cut normally when it rotates. As a result, the circular saw needs to be manually removed, readjusted and reinstalled, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0005] To solve the above-mentioned technical problems, a metal can-making processing tool is provided. This tool solves the problem that if the circular saw blade is installed backwards, so that the direction of the cutter head is opposite to the rotation of the motor output shaft, the circular saw cannot make normal cutting when it rotates. This requires manual removal, readjustment and reinstallation of the circular saw, which is time-consuming, labor-intensive and inefficient.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a metal can-making processing tool, including a circular saw blade and a plurality of cutting heads arranged around the outer periphery of the circular saw blade. A circular groove is provided on one side of the circular saw blade, and a reversing mechanism for adjusting the cutting direction of the cutting heads is built into the circular groove.

[0007] The reversing mechanism includes a movable ring rotatably disposed within the annular groove, an annular clearance groove formed on the outer periphery of the movable ring, and several sets of driving parts disposed within the annular clearance groove, with each set of driving parts corresponding to one of the cutter heads.

[0008] The driving unit includes a transmission column laterally disposed inside the annular clearance groove and a bevel gear disk fixed to the inner wall of the bottom end of the annular clearance groove. One end of the transmission column rotatably passes through the circular saw blade and is fixed with a connecting block. The connecting block is detachably connected to the cutter head. The other end of the transmission column is fastened with a bevel gear that meshes with the bevel gear disk.

[0009] Preferably, the other side of the circular saw blade has two arc-shaped movable slots, and a sliding post fixed to the movable ring is slidably disposed in the inner side of the arc-shaped movable slot. The end of the sliding post is fixed with a movable piece that fits against the surface of the circular saw blade.

[0010] Preferably, a connecting piece is fixed to the side of one of the movable pieces, and a locking screw is threaded through the connecting piece. Two locking screw holes are symmetrically opened on the bottom surface of the circular saw blade, and the locking screw corresponds to one of the locking screw holes.

[0011] Preferably, a positioning stud is vertically fixed to one side of the connecting block facing the cutter head, and the cutter head is provided with a mounting screw hole that matches the positioning stud.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] (1) By setting the reversing mechanism, if the circular saw blade is installed in reverse on the motor output shaft, the movable ring in the reversing mechanism only needs to be rotated in the circular groove. Several cutters can be rotated synchronously under the action of the corresponding drive unit. Compared with the existing operation, there is no need to manually disassemble and reassemble the circular saw blade. The cutting direction can be quickly changed in a short time, thereby effectively improving the work efficiency and enhancing the practicality.

[0014] (2) By setting up the mounting screw hole and positioning stud, compared with the existing technology where the cutter head and the circular saw blade are directly connected as a whole, it is convenient to easily replace the damaged cutter head by simply turning the screw head and removing the positioning stud from the mounting screw hole after a certain period of use, without having to discard the circular saw blade and the cutter head as a whole. This reduces costs and increases utilization to a certain extent. Attached Figure Description

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1 As shown, a metal can-making tool includes a circular saw blade 1 and a plurality of cutter heads 2 arranged around the outer periphery of the circular saw blade 1.

[0024] When in use, the circular saw blade 1 is pre-installed on the output shaft of the cutting motor and securely connected to the motor output shaft. When the cutting motor is turned on, the output shaft of the motor will rotate the circular saw blade 1 and the cutter head 2 together, which facilitates the effective cutting of the workpiece material.

[0025] Furthermore, referring to Figure 1-5 As shown, it is worth noting that one side of the circular saw blade 1 is provided with an annular groove, and the annular groove contains a reversing mechanism for changing the cutting direction of the blade head 2.

[0026] The reversing mechanism includes a movable ring 3 rotatably disposed in a circular groove, an annular clearance groove 4 opened on the outer periphery of the movable ring 3, and several sets of driving parts disposed in the annular clearance groove 4, with each set of driving parts corresponding to a number of cutter heads 2.

[0027] By setting up a reversing mechanism, if the circular saw blade 1 is installed backwards on the motor output shaft, the movable ring 3 in the reversing mechanism only needs to be rotated in the circular groove. Several cutter heads 2 can be synchronously flipped under the action of the corresponding drive unit. Compared with the existing operation, there is no need to manually and cumbersomely disassemble and reassemble the circular saw blade 1. The cutting direction can be quickly changed in a short time, thereby effectively improving work efficiency and enhancing practicality.

[0028] Furthermore, referring to Figure 3-4 As shown, it is worth noting that the driving part includes a transmission column 6 arranged laterally in the inner side of the annular clearance groove 4 and a bevel gear disk 8 fixed on the inner wall of the bottom end of the annular clearance groove 4. One end of the transmission column 6 rotates through the circular saw blade 1 and is fixed with a connecting block 5. The connecting block 5 is detachably connected to the cutter head 2. The other end of the transmission column 6 is tightly sleeved with a bevel gear 7 that meshes with the bevel gear disk 8.

[0029] When the movable ring 3 is rotated, the bevel gear disk 8 can rotate synchronously with the movable ring 3 and mesh with the bevel gear 7 in the drive unit in real time, thereby effectively providing rotational power to the transmission column 6, the connecting block 5 and the cutter head 2 as a whole.

[0030] Furthermore, referring to Figure 1 As shown, it is worth noting that two arc-shaped movable slots 9 are opened on the other side of the circular saw blade 1. A sliding column fixed to the movable ring 3 is slidably arranged in the inner side of the arc-shaped movable slot 9. The end of the sliding column is fixed with a movable piece 10 that is in contact with the surface of the circular saw blade 1.

[0031] Simply slide one of the movable pieces 10 on the surface of the circular saw blade 1 to make the sliding column slide from one side to the other inside the arc-shaped movable slot 9, thereby causing the movable ring 3 to rotate synchronously and in the same direction within the circular groove, so that the cutter head 2 can be flipped.

[0032] Furthermore, referring to Figure 1 As shown, it is worth noting that a connecting piece 11 is fixed to the side of one of the movable pieces 10, and a locking screw 12 is threaded through the connecting piece 11. Two locking screw holes 13 are symmetrically opened on the bottom surface of the circular saw blade 1, and the locking screw 12 corresponds to one of the locking screw holes 13.

[0033] When it is necessary to adjust the cutting direction of the cutter head 2, manually tighten the locking screw 12 in advance so that the locking screw 12 comes out from the inside of one of the locking screw holes 13, thereby releasing the fixation of the movable ring 3 and facilitating the subsequent rotation of the movable ring 3.

[0034] Then, after the sliding column is slid from one side to the other inside the arc-shaped movable slot 9, so that the cutter head 2 is flipped, the locking screw 12 moves to the position corresponding to the other locking screw hole 13. Then, the locking screw 12 is turned again so that the locking screw 12 passes into the inside of the other locking screw hole 13 under the thread structure, so that the movable ring 3 is locked again, ensuring the stability of the cutter head 2 after flipping.

[0035] Furthermore, referring to Figure 5 As shown, it is worth noting that the connecting block 5 is vertically fixed with a positioning stud 14 on one side facing the cutter head 2, and the cutter head 2 has a mounting screw hole that matches the positioning stud 14.

[0036] By using the mounting screw hole and positioning stud 14, compared to the existing technology where the cutter head 2 is directly and integrally connected to the circular saw blade 1, it is convenient to easily replace the damaged cutter head 2 by simply turning the cutter head 2 after a certain period of use, so that the positioning stud 14 can be removed from the mounting screw hole. This eliminates the need to discard the entire circular saw blade 1 and cutter head 2, thereby reducing costs and increasing utilization to a certain extent.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
