For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0060] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0061] See also Figure 1 The embodiment of the present application provides a shearing device 100. The shearing device 100 is used for quickly cutting materials such as metal and plastic, for example, cutting iron sheets, opening holes in air ducts, and grooving pipes.

[0062] See also Figure 1 The shearing device 100 includes a driving mechanism 10, a carrying mechanism 20 and a blade mechanism 30. The blade mechanism 30 is connected to the carrying mechanism 20 and the driving mechanism 10. The carrying mechanism 20 is connected to the driving mechanism 10. The carrying mechanism 20 supports the blade mechanism 30. The driving mechanism 10 provides power to the blade mechanism 30, so that the blade mechanism 30 moves under the drive of the driving mechanism 10 to achieve a cutting action.

[0063] See also Figure 1 and Figure 2 The driving mechanism 10 includes a driving member 11 and a cam transmission assembly 12 connected to the driving member 11.

[0064] The bearing mechanism 20 includes a bearing housing 21 and a connecting assembly 22. One end of the connecting assembly 22 is detachably connected to the driving member 11, and the other end of the connecting assembly 22 is connected to the bearing housing 21. One end of the cam transmission assembly 12 away from the driving member 11 extends into the bearing housing 21.

[0065] The blade mechanism 30 includes a fixed blade 31 and a movable blade 32. The fixed blade 31 is connected to the bearing housing 21, and the movable blade 32 is rotatably connected to the fixed blade 31. One end of the movable blade 32 close to the bearing housing 21 extends into the bearing housing 21 and is connected to one end of the cam transmission assembly 12 away from the driving member 11.

[0066] During the implementation of the shearing device 100, the driving member 11 drives the cam transmission assembly 12 to rotate, and the cam transmission assembly 12 drives the movable blade 32 to move, so that the movable blade 32 rotates relative to the fixed blade 31, and the movable blade 32 reciprocates close to or away from the fixed blade 31. At this time, the movable blade 32 and the fixed blade 31 cyclically open and close, so that the movable blade 32 and the fixed blade 31 cut the material.

[0067] Thus, during the cutting process, when the movable blade 32 and the fixed blade 31 are in the open state, the metal material is placed between the movable blade 32 and the fixed blade 31, and then the driving member 11 drives the movable blade 32 and the fixed blade 31 to close. At this time, the movable blade 32 and the fixed blade 31 cut the material. Since the shearing device 100 has a simple structure, a small size, and is powered by the driving member 11, the convenience of cutting the material is improved. In addition, when the shearing device 100 cuts the metal material, the shearing device 100 uses the movable blade 32 and the fixed blade 31 to cyclically open and close to complete the cutting of the metal material. Sparks will not appear during the cutting process, which is conducive to reducing the probability of explosion accidents. Furthermore, the shearing device 100 is easy to operate. The operator only needs to start the driving member 11 and then align the movable blade 32 and the fixed blade 31 with the metal material to achieve cutting.

[0068] In this embodiment, the driving member 11 can be a hand drill, for example, a rechargeable hand drill or a plug-in hand drill. By using a hand drill as a power source, the volume of the shearing device 100 can be reduced, making it easier for operators to carry and operate.

[0069] See also Figure 2 and Figure 3 The cam transmission assembly 12 includes a transmission shaft 121 and an eccentric cam 122. One end of the transmission shaft 121 is connected to the driving member 11, and the other end of the transmission shaft 121 extends into the bearing housing 21. The eccentric cam 122 is connected to the other end of the transmission shaft 121. Specifically, the rotation center of the transmission shaft 121 and the rotation center of the eccentric cam 122 are staggered. The eccentric cam 122 is connected to the movable blade 32. When the driving member 11 drives the transmission shaft 121 to rotate, the transmission shaft 121 drives the eccentric cam 122 to realize eccentric rotation, and the eccentric cam 122 drives the movable blade 32 to move.

[0070] See also Figure 1 and Figure 3 In this embodiment, the bearing shell 21 is a rectangular parallelepiped, and a receiving chamber 211 is provided inside the bearing shell 21 . The transmission shaft 121 extends into the bearing shell 21 and rotates relative to the bearing shell 21 . The eccentric cam 122 is located in the receiving chamber 211 .

[0071] In this embodiment, a bearing 123 is sleeved on the transmission shaft 121 , and the transmission shaft 121 is connected to the bearing housing 21 via the bearing 123 , thereby facilitating improving the stability of the transmission shaft 121 driving the eccentric cam 122 to rotate under the drive of the driving member 11 .

[0072] See also Figure 1 , the connecting assembly 22 includes a snap ring 221, two connecting members 222 and a plurality of fixing members 223. The snap ring 221 is annular, and is sleeved on the outer side of the driving member 11 and snapped with the driving member 11. The two connecting members 222 are arranged at intervals, and one end of the two connecting members 222 abuts against the snap ring 221, and the other ends of the two connecting members 222 are respectively connected to the two sides of the bearing shell 21. The plurality of fixing members 223 can be bolts, and at least one fixing member 223 is passed through each connecting member 222, and the fixing member 223 is connected to the snap ring 221, and the two connecting members 222 are connected to the snap ring 221 through the plurality of fixing members 223. In this way, since the fixing member 223 is a bolt, the operator can easily disassemble and assemble the connecting member 222 and the snap ring 221.

[0073] In this embodiment, the snap ring 221 includes a first snap ring 2211 and a second snap ring 2212. The first snap ring 2211 and the second snap ring 2212 are both semi-annular, and the first snap ring 2211 and the second snap ring 2212 are respectively abutted against the opposite sides of the driving member 11, and the two ends of the first snap ring 2211 are respectively abutted against the two connecting members 222, and the two ends of the second snap ring 2212 correspond to the two ends of the first snap ring 2211 one by one and are respectively abutted against the side of the two connecting members 222 away from the first snap ring 2211, and the two ends of the first snap ring 2211 are respectively connected to a fixing member 223, and the two fixing members 223 on the first snap ring 2211 pass through the two connecting members 222 and are connected to the second snap ring 2212. In this way, when assembling the snap ring 221 to the driving member 11, the operator first places the first snap ring 2211 and the second snap ring 2212 against the opposite sides of the driving member 11 respectively, and installs the two connecting members 222 between the first snap ring 2211 and the second snap ring 2212, and finally uses the fixing member 223 to connect the first snap ring 2211, the connecting member 222 and the second snap ring 2212. By setting the snap ring 221 to a split structure, it is convenient to quickly assemble the connecting component 22 and the driving member 11.

[0074] See also Figure 1 and Figure 4 , the two connecting members 222 each include a connecting body 2221, a first fixing portion 2222, a mounting portion 2223 and a second fixing portion 2224. The connecting body 2221 is in the shape of an elongated strip, and a first waist-shaped hole 2225 extending along the extending direction of the connecting body 2221 is provided on the connecting body 2221. The first fixing portion 2222 may be a bolt, and the first fixing portion 2222 is passed through the first waist-shaped hole 2225. The mounting portion 2223 is in the shape of a block, and the mounting portion 2223 abuts against the connecting body 2221 and is connected to the first fixing portion 2222. The connecting body 2221 is connected to the mounting portion 2223 through the first fixing portion 2222. The second fixing portion 2224 may also be a bolt, and the second fixing portion 2224 is passed through the mounting portion 2223 and is spaced apart from the first fixing portion 2222. The second fixing portion 2224 is connected to the bearing shell 21. In this way, since the mounting part 2223 and the carrying shell 21 are connected by bolts, the mounting part 2223 and the carrying shell 21 are more convenient to assemble and disassemble. Since the connecting body 2221 is provided with a first waist-shaped hole 2225, when the connecting body 2221 is assembled with the carrying shell 21 through the mounting part 2223, the operator can loosen the first fixing part 2222 and adjust the position of the first fixing part 2222 in the first waist-shaped hole 2225 according to the actual assembly situation, and finally tighten the first fixing part 2222, so as to facilitate the adjustment of the relative position of the carrying shell 21 and the connecting body 2221.

[0075] In this embodiment, a second waist-shaped hole 2227 extending along the extension direction of the connecting body 2221 is opened at one end of the connecting body 2221 away from the first waist-shaped hole 2225. The second waist-shaped hole 2227 is spaced apart from the first waist-shaped hole 2225. The fixing piece 223 on the first clamping ring 2211 passes through the second waist-shaped hole 2227 and is connected to the second clamping ring 2212.

[0076] See also Figure 4 and Figure 5 The connecting member 222 further includes a connecting portion 2226, which is connected to one end of the connecting body 2221 away from the second waist-shaped hole 2227. The thickness of the connecting portion 2226 is smaller than the thickness of the connecting body 2221 in a direction perpendicular to the extending direction of the connecting body 2221. The connecting portion 2226 is provided with a third waist-shaped hole 2228 extending along the extending direction of the connecting body 2221. Specifically, in another connection mode of the connecting assembly 22, the two sides of the connecting portion 2226 are respectively in contact with the first clamping ring 2211 and the second clamping ring 2212, and the fixing member 223 on the first clamping ring 2211 passes through the third waist-shaped hole 2228 and is connected to the second clamping ring 2212. At this time, the first fixing portion 2222 is passed through the second waist-shaped hole 2227 and connected to the mounting portion 2223.

[0077] Due to the different types of hand drills, the calibers of the hand drill connection part 2226 are different. When the first snap ring 2211 and the second snap ring 2212 are connected to one end of the second waist-shaped hole 2227, the annular diameter surrounded by the first snap ring 2211 and the second snap ring 2212 is larger, and the first snap ring 2211 and the second snap ring 2212 are suitable for installation on a hand drill with a larger caliber. When the first snap ring 2211 and the second snap ring 2212 are connected to the connection part 2226, the annular diameter surrounded by the first snap ring 2211 and the second snap ring 2212 is smaller, and the first snap ring 2211 and the second snap ring 2212 are suitable for installation on a hand drill with a smaller caliber. In this way, by providing the second waist-shaped hole 2227 and the third waist-shaped hole 2228 on the connecting member 222, the relative position of the connecting member 222 and the clamping ring 221 can be adjusted, so as to facilitate the assembly of the connecting assembly 22 with different models of driving members 11.

[0078] See also Figure 3 The blade mechanism 30 further includes a connecting frame 33, the fixed blade 31 is detachably connected to the connecting frame 33, the movable blade 32 is detachably rotatably connected to the connecting frame 33, the fixed blade 31 is connected to the bearing housing 21 through the connecting frame 33, and the movable blade 32 is connected to the fixed blade 31 through the connecting frame 33. For example, the fixed blade 31 and the movable blade 32 are both fixed to the connecting frame 33 by bolts, and when the blades are worn, the operator can replace them at any time.

[0079] In this embodiment, a spring gasket (not shown) may be added between the fixed blade 31 and the connecting frame 33 or a spring gasket may be added between the movable blade 32 and the connecting frame 33 to adjust the gap between the fixed blade 31 and the movable blade 32 .

[0080] In this embodiment, a groove 321 is provided at one end of the movable blade 32 located in the bearing housing 21, and an end of the cam transmission assembly 12 away from the driving member 11 is rotatably disposed in the groove 321 and abuts against the groove wall of the groove 321. Specifically, the eccentric cam 122 of the cam transmission assembly 12 is rotatably disposed in the groove 321 and abuts against the groove wall of the groove 321. When the eccentric cam 122 rotates, the eccentric cam 122 rotates relative to the movable blade 32. At this time, the eccentric cam 122 drives the movable blade 32 to rotate relative to the fixed blade 31 by abutting against the groove wall of the groove 321, so that the fixed blade 31 and the movable blade 32 are cyclically opened and closed to cut the material.

[0081] See also Figure 6 , Figure 7 and Figure 8 Specifically, the groove wall of the groove 321 has a first side wall 322, a second side wall 323, a third side wall 324 and a fourth side wall 325. The first side wall 322, the second side wall 323, the third side wall 324 and the fourth side wall 325 are connected in sequence, and the angle between the first side wall 322 and the second side wall 323 is an obtuse angle, the angle between the second side wall 323 and the third side wall 324 is an acute angle, and the angle between the third side wall 324 and the fourth side wall 325 is an obtuse angle. The end of the cam transmission component 12 away from the driving member 11 abuts against the first side wall 322 and the fourth side wall 325. The cam transmission component 12 pushes the first side wall 322 to make the movable blade 32 close to the fixed blade 31, and the cam transmission component 12 pushes the fourth side wall 325 to make the movable blade 32 away from the fixed blade 31. For ease of description, a reference point A is selected on the eccentric cam 122. When the eccentric cam 122 rotates relative to the movable blade 32 and point A rotates to a position corresponding to the first side wall 322, the eccentric cam 122 presses the movable blade 32 downward through the fourth side wall 325, and the fixed blade 31 and the movable blade 32 are in an open state; when point A rotates to a position corresponding to the fourth side wall 325, the eccentric cam 122 pushes the movable blade 32 upward through the first side wall 322, and the fixed blade 31 and the movable blade 32 are in a closed state. When the eccentric cam 122 rotates continuously, the fixed blade 31 and the movable blade 32 open and close cyclically to cut the material.

[0082] The working process of the shearing device 100 provided in the embodiment of the present application is roughly as follows:

[0083] The driving member 11 drives the transmission shaft 121 to rotate, and the transmission shaft 121 drives the eccentric cam 122 to rotate. At this time, the eccentric cam 122 rotates relative to the movable blade 32. When point A on the eccentric cam 122 rotates to a position corresponding to the first side wall 322, the eccentric cam 122 presses the movable blade 32 downward through the fourth side wall 325. At this time, the movable blade 32 moves upward, and the fixed blade 31 and the movable blade 32 are in an open state; when point A rotates to a position corresponding to the fourth side wall 325, the eccentric cam 122 pushes the movable blade 32 upward through the first side wall 322. At this time, the movable blade 32 moves downward, and the fixed blade 31 and the movable blade 32 are in a closed state. When the eccentric cam 122 rotates continuously, the fixed blade 31 and the movable blade 32 open and close cyclically to cut the material.

[0084] To summarize, the shearing device 100 in the embodiment of the present application drives the cam transmission assembly 12 to rotate by setting a driving member 11, and the cam transmission assembly 12 drives the movable blade 32 to reciprocate close to or away from the fixed blade 31 to shear the material, so that the shearing device 100 has a simple structure and a small size, and the driving member 11 provides power to cut the material, thereby improving the convenience of cutting the material; in addition, when the shearing device 100 cuts metal materials, the shearing device 100 uses the movable blade 32 and the fixed blade 31 to cyclically open and close to complete the cutting of the metal material, and no sparks will appear during the cutting process, which is beneficial to reduce the probability of explosion accidents.
