[0004] For example, the prior art in the above-mentioned patent cuts a batch of metal plates of the same size. The former requires the operator to separately operate the cutting mechanism and the adjusting mechanism to fix and cut the metal plates. Firstly, because the operator needs to operate two sets of different mechanisms, the operation time is relatively long, resulting in the need to improve the cutting efficiency. Secondly, the two sets of different mechanisms require different driving sources, so the overall cost of the equipment is relatively high. Summary of the invention

After the metal plate is cut, the first driving member drives the sliding frame and the cutting assembly to reset. During the sliding of the sliding frame, the linkage assembly is used to release the fixing of the metal plate by the fixing assembly.

[0016] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] See also Figure 1-8 A hardware 101 cutting device provided by an embodiment of the present invention includes a frame 1 and a support plate 11 arranged on the frame 1, and also includes a cutting component 2, two fixing components 3 and a first driving component 9. The cutting component 2 is vertically slidably connected to the frame 1 through a sliding frame 12; the two fixing components 3 are used to cooperate with the support plate 11 to clamp and fix the hardware 101. The fixing component 3 includes a fixing sleeve 31, a rotating disk 32, a fixing disk 33 and a pressing plate 34. The fixing sleeve 31 is fixedly connected to the frame 1, and the rotating disk 32 is rotatably connected in the fixing sleeve 31. An arc groove 321 is provided on the rotating disk 32, and the fixing disk 33 is fixedly connected in the fixing sleeve 31. A limited position through groove 331 is provided on the fixing disk 33, and the axis of the rotating disk 32 and the axis of the fixing disk 33 are collinear. The center of the circle where the arc groove 321 is located is not the same as the center of the circular surface of the turntable 32. The arc groove 321 bends from a position away from the center of the circular surface of the turntable 32 to a position close to the center of the circular surface. A first slider is slidably connected to the arc groove 321, and the first slider passes through the limiting groove 331 and is fixedly connected to the pressure plate 34; the first driving member 9 is used to drive the sliding frame 12 to slide vertically. In the process of driving the sliding frame 12 to slide vertically, the first driving member 9 uses the linkage assembly 4 to fix the fixing assembly 3 to the hardware 101, and can release the fixation. Specifically, the first driving member 9 is a hydraulic cylinder, which includes a cylinder barrel and a piston rod. The cylinder barrel is fixedly installed on the frame 1, and the end of the piston rod away from the cylinder barrel is fixedly connected to the sliding frame 12, and the piston rod is slidably connected to the cylinder barrel.

[0018] like Figure 3The linkage assembly 4 includes a first rotating rod 41, a guide rod 42, a sliding sleeve 43 and a hinged rod 44. The first rotating rod 41 is coaxially fixedly connected to the rotating disk 32. The first rotating rod 41 is provided with a sliding groove 5, and the sliding groove 5 includes a connected transverse groove 51 and a spiral groove 52; the guide rod 42 is fixedly connected to the frame 1; the sliding sleeve 43 is slidably connected to the guide rod 42, and a ball rolling with the sliding groove 5 is arranged on the sliding sleeve 43; one end of the hinged rod 44 is hinged to the sliding frame 12, and the other end is hinged to the sliding sleeve 43, as shown in FIG. Figure 2 The cutting assembly 2 includes a second rotating rod 21, a cutting knife 22 and a second driving member 23. The second rotating rod 21 is rotatably connected to the sliding frame 12; the cutting knife 22 is coaxially connected to the second rotating rod 21; and the second driving member 23 is used to drive the second rotating rod 21 to rotate relative to the sliding frame 12.

[0019] Working principle: Place the metal plate to be cut on the support plate 11 and adjust the placement position, then drive the sliding frame 12 to slide vertically downward through the piston rod of the hydraulic cylinder. During the vertical downward sliding process of the sliding frame 12, the sliding frame 12 will push the sliding sleeve 43 to slide along the extension direction of the guide rod 42 through the hinge rod 44. During the sliding process of the sliding sleeve 43, the ball bearing (not shown in the figure) on the sliding sleeve 43 will first roll with the spiral groove 52 of the first rotating rod 41. During the rolling cooperation with the spiral groove 52, the ball bearing drives the first rotating rod 41 to rotate. The rotation of the first rotating rod 41 drives the rotating disk 32 to rotate. Due to the rotation of the rotating disk 32, the first slider on the arc groove 321 on the rotating disk 32 is fixed The restriction of the limiting groove 331 of the disk 33 allows the first slider to slide along the arc groove 321 and move vertically relative to the pressure plate 34. During the rolling cooperation between the ball and the spiral groove 52, the turntable 32 rotates to cause the pressure plate 34 to move vertically downward, and then the pressure plate 34 cooperates with the support plate 11 to fix the metal plate. Then the ball enters the transverse groove 51, the first rotating rod 41 temporarily stops rotating and the pressure plate 34 is in a fixed state for the metal plate, and the sliding frame 12 slides vertically downward. When the cutting knife 22 is about to contact the metal plate, the second driving member 23 is turned on, so that the second driving member 23 drives the second rotating rod 21 to rotate, and then the second rotating rod 21 cuts the metal plate with the cutting knife 22.

[0020] After the cutting is completed, the second driving member 23 stops working, and the piston rod of the hydraulic cylinder slides the sliding frame 12 vertically upward. The ball on the sleeve 43 first cooperates with the transverse groove 51, and after the ball enters the spiral groove 52, the first rotating rod 41 rotates, and then the turntable 32 rotates to make the pressure plate 34 move away from the metal plate to release the fixation of the metal plate.

[0021] Compared with the prior art, in the present invention, during the process of driving the sliding frame 12 and the cutting assembly 2 on the sliding frame 12 to move toward the metal plate through the first driving member 9, the sliding frame 12 will first use the linkage assembly 4 to enable the fixing assembly 3 to fix the metal plate placed on the support plate 11, and then the metal plate remains fixed by the fixing assembly 3, and the cutting assembly 2 continues to move toward the metal plate until the metal plate is cut. After the metal plate is cut, the first driving member 9 drives the sliding frame 12 and the cutting assembly 2 to reset, and the fixing assembly 3 releases the fixation of the metal plate through the linkage assembly 4 during the sliding of the sliding frame 12.

[0022] In this way, on the one hand, the operator only needs to control the first driving member 9 to drive the sliding frame 12 to slide vertically to change the position of the cutting component 2 and fix the metal plate. On the other hand, the first driving member 9 drives the sliding frame 12 to slide, and the sliding frame 12 can drive the fixing component 3 to change its state through the linkage component 4, thereby effectively reducing the use of power source and thus reducing the equipment cost.

[0023] Among them, the second driving member 23 is a driving motor, the ratchet 6 is coaxially fixedly connected to the second rotating rod 21, the slide plate 7 is slidably connected to the sliding frame 12, the slide plate 7 is provided with a pawl cooperating with the ratchet 6, the slide plate 7 is fixedly connected with a wedge block 71, and an elastic member 121 is provided in the sliding frame 12. Specifically, the elastic member 121 is a spring, one end of the spring is connected to the sliding frame 12, and the other end of the spring is connected to the slide plate 7. The elastic force of the elastic member 121 drives the slide plate 7 to slide horizontally, and a fixed block 13 abutting against the wedge block 71 is provided on the frame 1. The driving motor is a unidirectional driving motor. When the wedge block 71 is not in contact with Before the fixed block 13 abuts, the ratchet 6 on the second rotating rod 21 is acted upon by the pawl, making it impossible for the second rotating rod 21 to rotate. When the sliding frame 12 slides to the point where the wedge block 71 abuts against the fixed plate, the slide plate 7 slides horizontally and squeezes the spring. The movement of the slide plate 7 makes the pawl no longer cooperate with the ratchet 6, and then the one-way drive motor can make the second rotating rod 21 rotate. If the sliding frame 12 slides so that the wedge block 71 does not abut against the fixed block 13, the spring resets the slide plate 7, and then the pawl cooperates with the ratchet 6, so that as long as the cutting knife 22 is not in the cutting position, the cutting knife 22 cannot rotate, thereby making the device safer.

[0024] The frame 1 is also provided with an adjustment assembly 8 for adjusting the height of the support plate 11, and the adjustment assembly 8 includes a third rotating rod 81, two second sliders 82 and a guide column 83. The third rotating rod 81 is rotatably connected to the frame 1, and a first thread segment and a second thread segment are provided on the third rotating rod 81, and the first thread segment and the second thread segment are mutually reverse thread segments; the two second sliders 82 are slidably connected to the frame 1, and the two second sliders 82 are both threadedly connected to the third rotating rod 81, and the two second sliders 82 are both hinged with a connecting rod 821, and the other ends of the two connecting rods 821 are both hinged to the support plate 11; the guide column 83 is fixedly connected to the frame 1. On the frame 1, the support plate 11 is slidably connected to the guide column 83, and the two second sliders 82 can be made to slide horizontally by rotating the third rotating rod 81. While the second sliders 82 slide horizontally, they can pull or abut the support plate 11 through the connecting rod 821 so that the support plate 11 can slide vertically along the direction of the guide column 83, thereby changing the position of the support plate 11 relative to the frame 1, so that the device can batch cut metal plates of different thicknesses. It is worth mentioning that a motor is used here to drive the third rotating rod 81 to rotate and then the two second sliders 82 to slide, so that the rising height of the support plate 11 can be more accurate.

[0025] The sliding frame 12 is also provided with an arc plate 122 , which can prevent sparks from flying during the cutting process.

[0026] In another embodiment provided by the present invention, Figure 8The second driving member 23 is a driving motor. The ratchet 6 is coaxially fixedly connected to the second rotating rod 21. The slide frame 12 is slidably connected to the slide plate 7. The slide frame 12 is fixedly installed with an electric telescopic rod 73. The telescopic portion of the electric telescopic rod 73 is fixedly connected to the slide plate 7. The electric telescopic rod 73 can drive the slide plate 7 to slide horizontally. A height measuring sensor 72 is provided on the slide plate 7. The slide plate 7 is provided with a pawl that cooperates with the ratchet 6. The first driving member 9 is used to drive the slide frame 12 to slide vertically relative to the frame 1. The height of the slide frame 12 relative to the ground will change while sliding. Since the change in the height of the slide frame 12 will drive the change in the height of the height measuring sensor 72, the height measuring sensor 72 is relative to the ground. The measured value will change. When the height measuring sensor 72 sets a value, when the height of the height measuring sensor 72 is lower than this value, a signal will be transmitted to the electric telescopic rod 73, so that the slide plate 7 can be away from the ratchet 6, and then the pawl on the slide plate 7 is released from the ratchet 6. The drive motor is a unidirectional drive motor, and the drive motor can drive the cutting knife 22 to work. When the height of the height measuring sensor 72 is higher than the predetermined value, the electric telescopic rod 73 will drive the slide plate 7 to reset, and then the pawl on the slide plate 7 will cooperate with the ratchet 6 again, and the cutting knife 22 will no longer rotate. By limiting the activity of the cutting knife 22, the cutting knife 22 will no longer rotate when it exceeds the working range, so that the device can be safer.

[0027] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
