The application method and the principle of the technical scheme part in the specific embodiment are further described below with reference to the accompanying drawings:
when a plate to be bent is required to be bent, firstly, a worker places the plate to be bent at the top of the workbench 1 according to bending requirements, a bending area of the plate to be bent is positioned under a bending cutter 31, at the moment, the worker starts a motor 23, the motor 23 rotates positively, a power output shaft of the motor 23 rotates to drive a first transmission shaft 2 axially abutted with the motor to rotate, the first transmission shaft 2 rotates to drive a first threaded shaft section 21 and a second threaded shaft section 22 which are arranged in a mirror image on a shaft body of the first transmission shaft 2 to rotate, and the threads of the first threaded shaft section 21 and the second threaded shaft section 22 rotate in opposite directions, so that two first sliding blocks 24 which are respectively in threaded connection with the second threaded shaft section 22 of the first threaded shaft section 21 move in opposite directions along a second T-shaped sliding groove 18;
when the two first sliding blocks 24 move towards each other, the first connecting rods 26 which are in rotary connection with the first sliding blocks are driven by the first ear seat groups 25 arranged at the bottoms of the first sliding blocks to evolve from a horizontal arrangement state to a vertical arrangement state, namely, the included angles of the two first connecting rods 26 are gradually reduced, and then the driving plate 3 at the bottoms of the second ear seat groups 32 is driven by the second ear seat groups 32 which are in rotary connection with the first connecting rods 26 to move downwards, so that the driving plate 3 slides downwards along the second sliding grooves 17 through the second sliding blocks 33 which are symmetrically arranged at the two sides of the driving plate; the driving plate 3 moves downwards and drives the bending knife 31 arranged at one end of the bottom to move downwards so as to prepare the bending operation of the plate to be bent;
meanwhile, when the driving plate 3 moves downwards, as the height distance between the pressing plate 5 and the workbench 1 is smaller than the height distance between the bending knife 31 and the workbench 1, the pressing plate 5 is contacted with the plate to be bent firstly, the plate to be bent is pressed from the vertical direction, when the driving plate 3 continuously presses downwards, the pressing plate 5 presses the second connecting rod 52 which is in rotary connection with the fourth ear seat group 51 through the fourth ear seat group 51 symmetrically arranged at the top of the pressing plate, namely, the included angle between the two second connecting rods 52 is gradually increased, and then the third ear seat group 38 which is in rotary connection with the second connecting rod 52 drives the third sliding block 37 to slide along the first connecting shaft 35 in the third sliding groove 34, namely, the two third sliding blocks 37 which are arranged in mirror images are gradually gathered together along the length direction of the third sliding groove 34 from the initial state at the two sides of the third sliding groove 34, and further presses the first spring 36; redundancy is provided for continuous downward pressing of the driving plate 3, and the situation that the position of the pressing plate 5 is blocked when the driving plate 3 is continuously pressed downward is avoided; meanwhile, the downward pressure of the pressing plate 5 is gradually increased by continuously pressing the driving plate 3 downwards, so that the clamping effect of the plate to be bent in the vertical direction is ensured;
meanwhile, when the driving plate 3 moves downwards, the first driving rod 39 and the guiding and limiting rod 391 slide along the guiding and limiting groove 42 which is formed on the driving block 4 in a penetrating way; when the guide limit rod 391 slides along the guide limit groove 42, the position of the driving block 4 is kept unchanged, at this time, the guide limit rod 391 enters the first cavity 14 through the first chute 13 arranged at the top of the workbench 1, and the limitation of the transverse position of the first driving rod 39 at the top of the guide limit rod 391 is completed, so that when the first driving rod 39 slides along the oblique side of the guide limit groove 42, the driving block 4 is driven to slide along the first T-shaped chute 12 at the top of the workbench 1 through the second T-shaped slider 41 at the bottom of the driving block; the two driving blocks 4 move towards the middle, as the limiting plate 44 is arranged in the spring cavity 46 of the first connecting plate 43 extending into the clamping block 45, and the limiting plate 44 and the second spring 47 are arranged in the spring cavity 46, under the action of no external force, the two driving blocks 4 are towards the middle to drive the two clamping blocks 45 to be towards the middle, so that the clamping of the plate to be bent is finished, meanwhile, when the driving plate 3 is continuously pressed down, the first connecting plate 43 presses the second spring 47 through the limiting plate 44, redundancy is provided for the continuous pressing down of the driving plate 3, the situation that the position of the clamping block 45 is blocked when the driving plate 3 is continuously pressed down is avoided, meanwhile, the clamping force of the two clamping blocks 45 is gradually increased when the driving plate 3 is continuously pressed down, and the transverse clamping effect of the plate to be bent is ensured;
the transverse distance between the two fourth ear seat groups 51 is larger than the transverse distance between the two third ear seat groups 38, so that the movement range of the second connecting rod 52 between the fourth ear seat groups 51 and the third ear seat groups 38 can be limited, and the second connecting rod 52 is ensured not to be blocked vertically during movement; the transverse distance of the pressing plate 5 is smaller than the minimum transverse distance between the two first driving rods 39, so that collision between the pressing plate 5 and the clamping blocks 45 is avoided;
the transverse distance of the stop block 19 is slightly larger than the maximum transverse distance between the two second ear seat groups 32, so that when the first sliding block 24 moves to be attached to the stop block 19, the first connecting rod 26 is not in a vertical state, and further the condition that the first connecting rod 26 is blocked vertically is avoided;
when the plate is bent, an operator can release the plate to be bent only by reversing the motor 23.
The above embodiments are only for illustrating the technical solution of the present application, and are not limiting; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application.
