[0022] Reference Figures 1-6This utility model proposes a floor punching and shearing device that facilitates punch replacement. It includes a punching and shearing base 1, a gantry frame 2 fixedly mounted on the base 1, a drive slider 20 slidably mounted on the gantry frame 2, a hydraulic rod 3 fixedly mounted on the drive slider 20, and a mounting block 4 fixedly mounted on the output shaft of the hydraulic rod 3. The bottom surface of the mounting block 4 has a mounting hole, in which a punch 5 is detachably mounted. The inner wall of the mounting hole has a transverse groove, in which a positioning pin 6 is slidably mounted. The side of the punch 5 has a positioning hole that matches the end of the positioning pin 6. A pressure plate 7 is slidably mounted on the punch 5. A transmission mechanism is provided between the positioning pin 6 and the pressure plate 7. When the pressure plate 7 moves closer to the mounting block 4, it can drive the positioning pin 6 to disengage from the positioning hole through the transmission mechanism. The transmission mechanism can also drive the positioning pin 6 to insert into the positioning hole. When disassembling the punch 5, the pressure plate 7 can be pressed, causing it to move closer to the mounting block 4 until the pressure plate 7 drives the positioning pin 6 to disengage from the positioning hole through the transmission mechanism, allowing the punch 5 to be pulled out. Disassembly is convenient. A reset mechanism is installed on the mounting block 4. The reset mechanism is used to drive the pressure plate 7 to slide and reset on the punch 5. When installing the punch 5, the pressure plate 7 is pressed down first, so that the positioning pin 6 is fully retracted into the transverse groove. Then, the new punch 5 is inserted into the mounting hole, the pressure plate 7 is released, and the reset mechanism drives the pressure plate 7 to slide and reset. At the same time, the transmission mechanism is not subjected to the squeezing action of the pressure plate 7. Under the action of the transmission mechanism, the positioning pin 6 is driven to insert into the positioning hole on the mounting shank of the punch 5 to complete the installation operation. In the specific punching and shearing operation, the plate is placed on the punching and shearing base 1, and the drive slider is... 20. The working drive hydraulic rod 3 reaches the designated position, and the working drive of the hydraulic rod 3 drives the mounting block 4 and the punch 5 to descend and perform punching and shearing operations on the floor. The pressure plate 7 first abuts against the floor, and the mounting block 4 and the punch 5 continue to descend under the action of the hydraulic rod 3, so that the punch 5 punches and shears the floor. After punching and shearing is completed, the hydraulic rod 3 drives the punch 5 to rise and reset. Under the action of the reset mechanism, the pressure plate 7 can always keep the edge of the floor that has been punched and sheared pressed down, reducing the risk of the edge of the floor being lifted and burrs being generated when the punch 5 is pulled out, and ensuring the smoothness of the punched and sheared edge.

[0023] like Figure 2 and Figure 3As shown, the transmission mechanism includes a trapezoidal block 8, a retraction spring 9, a disassembly block 10, and an ejection spring 11. The trapezoidal block 8 is fixedly connected to one end of the positioning pin 6. A retraction groove is provided in the mounting block 4 to slide with the trapezoidal block 8. The retraction spring 9 is fitted onto the positioning pin 6, and both ends of the retraction spring 9 abut against the inner wall of the end of the retraction groove and the trapezoidal block 8, respectively. A transmission groove communicating with the retraction groove is provided in the mounting block 4. The disassembly block 10 is slidably installed in the transmission groove. The side of the trapezoidal block 8 away from the positioning pin 6 slides with one side of the disassembly block 10. The disassembly block 10 extends to the outside of the mounting block 4 near the punch 5. The side of the disassembly block 10 that contacts the trapezoidal block 8 is composed of a plane and an inclined plane. When the positioning pin 6 fixes the punch 5, the trapezoidal block... The trapezoidal block 8 rests against the plane of the disassembly block 10. When the punch 5 is subjected to external force, the trapezoidal block 8 cannot move laterally, thus ensuring the position of the positioning pin 6 and the punch 5. The ejector spring 11 is installed in the transmission groove, and the two ends of the ejector spring 11 rest against the transmission groove and the end of the disassembly block 10, respectively. The ejector spring 11 is always in a compressed state. During disassembly, the pressure plate 7 is pushed to move until the pressure plate 7 rests against the end of the disassembly block 10 and pushes the disassembly block 10 to slide in the transmission groove. Under the action of the retraction spring 9, the trapezoidal block 8 is pushed to slide along the inclined surface of the disassembly block 10. The positioning pin 6 is driven by the trapezoidal block 8 to slide synchronously. The positioning pin 6 gradually disengages from the positioning hole, and the worker disassembles the punch 5. The disassembly and assembly are simple and convenient.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, the reset mechanism includes a reset plate 12, an anti-detachment slider 13, and a reset spring 14. One end of the reset plate 12 is fixedly connected to the pressure plate 7. The mounting block 4 has a reset groove that slides with the reset plate 12. The anti-detachment slider 13 is fixedly installed on one side of the reset plate 12. The mounting block 4 has an anti-detachment groove that slides with the anti-detachment slider 13. The two ends of the reset spring 14 abut against the inner walls of the anti-detachment slider 13 and the anti-detachment groove, respectively. When the hydraulic rod 3 is working, the pressure plate 7 abuts against the floor. When the hydraulic rod 3 continues to work, the reset plate 12 retracts into the reset groove of the mounting block 4, so that the pressure plate 7 always adheres to the surface of the floor. At the same time, the reset plate 12 drives the anti-detachment slider 13 to move synchronously. After the punching and shearing operation is completed, the rebound action of the reset spring 14 drives the anti-detachment slider 13 and the reset spring 14 to slide synchronously, so that the pressure plate 7 is reset, so as to facilitate the next punching and shearing operation.

[0025] In actual operation, the pressure plate 7 needs to slide to a certain position to touch the end of the disassembly block 10. However, during repeated punching and shearing operations, the pressure plate 7 will inevitably touch the disassembly block 10, which may cause the punch 5 to loosen or even fall off. Therefore, the following design is proposed.

[0026] like Figure 2As shown, the mounting block 4 is equipped with a blocking component, which can prevent the pressure plate 7 from contacting the end of the disassembly block 10. During the punching and shearing operation, the blocking component prevents the pressure plate 7 from contacting the end of the disassembly block 10, thereby ensuring the firmness and stability of the punch 5.

[0027] like Figure 2 As shown, the obstruction assembly includes an obstruction block 15 and an obstruction spring 16. The side of the mounting block 4 is provided with an obstruction groove that slides with the obstruction block 15. The end of the reset plate 12 can abut against one side of the obstruction block 15. A recessed groove is provided on one side of the obstruction block 15. When the reset plate 12 enters the recessed groove, the pressure plate 7 can push the disassembly block 10 to retract in the transfer groove. The obstruction spring 16 is located in the obstruction groove. The two ends of the obstruction spring 16 abut against the inner wall of the end of the obstruction groove and the end of the obstruction block 15, respectively. During normal punching and shearing operations, under the rebound action of the obstruction spring 16, the obstruction block 15 moves outward from the mounting block 4. When the pressure plate 7 moves closer to the mounting block 4, the end of the reset plate 12 will abut against the wide section of the obstruction block 15, so that the pressure plate 7 cannot touch the end of the disassembly block 10. During disassembly, the obstruction block 15 is pressed, so that the end of the reset plate 12 can enter the recessed groove on the obstruction block 15, so that the pressure plate 7 pushes the disassembly block 10 to move synchronously.

[0028] like Figure 2 and Figure 6 As shown, a heating ring 17 is fixedly installed on the side of the pressure plate 7 away from the mounting block 4. A movable switch is installed on the reset plate 12. The movable switch is used to control the circuit disconnection of the heating ring 17. The movable switch includes a movable end 18 and an elastic contact piece 19. A switch slot communicating with the reset slide is opened in the mounting block 4. The movable end 18 is fixedly installed on one side of the reset plate 12. The movable end 18 slides in the switch slot and is electrically connected to the heating ring 17. The elastic contact piece 19 is installed in the switch slot. The movable end 18 can slide on the side of the elastic contact piece 19. In the normal state, the movable end 18 and the elastic contact piece 19 are in the disconnected state. When punching and shearing operations are performed, when the distance between the pressure plate 7 and the mounting block 4 is shortened, that is, when the movable end 18 slides in the switch slot, the movable end 18 contacts the elastic contact piece 19, so that the heating ring 17 is energized. The heating ring 17 is energized and heats up. The heated heating ring 17 heats up the edge of the punched and sheared edge of the floor, reducing the generation of burrs on the punched and sheared edge.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
