Referring to fig. 2 and 3, a plate transmission mechanism is arranged on the upper end surface of the workpiece movable platform 11; the plate transmission mechanism comprises two parallel conveying belts 5, and the output directions of the two conveying belts 5 face to the center of the hinge ring 13; a conveyor belt driving wheel 51 and a conveyor belt driven wheel 52 are sleeved in each conveyor belt 5, so that on one hand, a workpiece is positioned by the two sets of conveyor belt driving wheels 51 or the two sets of conveyor belt driven wheels 52, and the workpiece is kept in a vertical state in the conveying process (the vertical state of the workpiece is a processed state of the workpiece); on the other hand, two groups of belt wheels drive two conveyer belts 5 to transmit; under the transmission action of a rotating transmission assembly arranged in the workbench 1, the bending driving handle 3 can drive the conveying belt driving wheel 51 to drive the conveying belt 5 to transmit in the output direction in the resetting and rotating process after the bending is finished, and the resetting and rotating process is a process that the bending driving handle 3 bends the workpiece leftwards or rightwards and then returns to the middle position state (the state shown in fig. 1).
Referring to fig. 1, 4 and 5, preferably, a rotating shaft 2 is rotatably sleeved in the hinge ring 13, and the bending driving handle 3 is slidably sleeved at the lower end position of the rotating shaft 2; the lower extreme position department of axis of rotation 2 is equipped with the spline structure that can rotate the location, drives turning to the location between the handle 3 through this spline structure realization axis of rotation 2 and bending for axis of rotation 2 drives handle 3 with bending and only can take place relative movement, can not take place relative rotation. Because the device drives the conveying belt 5 to transmit by utilizing the resetting and rotating process of the bending driving handle 3, and the device clamps the workpiece into the plate clamping gap 311 between the two plate clamping blocks 31 to provide the clamping effect during bending, the bending driving handle 3 is set to be in a structure of sliding up and down, so that the two states of clamping and clamping cancellation can be switched at any time, and the rotation of the rotating shaft 2 is not influenced.
In one embodiment, the rotary transfer assembly comprises:
referring to fig. 6 and 7, two driven gears 64 coaxially connected to the two belt driving wheels 51, respectively;
referring to fig. 4, a driving gear 61 provided at an upper position of the rotation shaft 2;

referring to fig. 12, a shift lever 66 is fixedly arranged at the lower end of the switching member 62, an arc-shaped groove 111 corresponding to the motion track of the shift lever 66 is arranged on the lower end surface of the workpiece movable platform 11, and the shift lever 66 passes through the arc-shaped groove 111 and extends to the outside of the workbench 1; the switch 62 can be driven to change the angle more conveniently by the shift lever 66.
Preferably, a predetermined distance is left between the two driven gears 64, two ends of the switching member 62 are provided with supporting springs 65, the other ends of the supporting springs 65 are fixedly connected to the inner wall of the workbench 1, and the two supporting springs 65 support the switching member 62 in a centered state (shown in fig. 7 and 11) under the condition of no external force, and the switching member 62 in the centered state can enable the connecting gear 63 not to be meshed with the driven gears 64 on both sides. When the bending driving handle 3 bends a workpiece, the switching piece 62 is in a centering state, so that the bending driving handle 3 cannot drive the conveying belt 5 to convey the workpiece, and the conveying distance of the conveying belt 5 can be controlled through the structure, and when a worker wants to convey the workpiece, the worker only needs to stir the deflector rod 66 to enable the driven gear 64 to be meshed with the corresponding connecting gear 63, so that the workpiece can be conveyed; when the conveying distance of the workpiece reaches a preset distance, the shifting rod 66 is only required to be canceled, the switching piece 62 rebounds to the centering state under the action of the supporting spring 65, and the bending driving handle 3 cannot drive the conveying belt 5 to continue conveying even in the resetting and rotating process.
The rotary conveying assembly works;
when the bending driving handle 3 is in the process of bending the workpiece, the deflector rod 66 is not pulled;
under the supporting action of the supporting springs 65 positioned at two sides, the switching piece 62 is in a centering state, the connecting gear 63 is not meshed with any one driven gear 64, the driving gear 61 cannot form transmission with the driven gear 64, the conveying belt driving wheel 51 has no driving force, and the conveying belt 5 does not work;
when the conveying assembly is rotated to transmit (the bending driving handle 3 is in a reset rotation process);
referring to fig. 3 and 9, when the bending driving handle 3 is in the process of returning and rotating after bending to the right, the driving gear 61 rotates clockwise, the hand-held shift lever 66 drives the switching piece 62 to rotate to the left, the connecting gear 63 is meshed with the left driven gear 64, the left driven gear 64 drives the connected conveyor belt driving wheel 51 to rotate, the left conveyor belt 5 conveys the workpiece (the right conveyor belt 5 has a driven effect and can also follow the transmission), and the conveyor belt 5 conveys the workpiece to the direction of the hinge ring 13;
referring to fig. 3 and 10, when the bending driving handle 3 is in the process of returning and rotating after bending to the left, the driving gear 61 rotates counterclockwise, the hand-held lever 66 drives the switching member 62 to rotate to the right, the connecting gear 63 is meshed with the driven gear 64 on the right, the driven gear 64 on the right drives the conveyor belt driving wheel 51 connected with the same to rotate, the conveyor belt 5 on the right conveys the workpiece (the conveyor belt 5 on the left plays a role of driving, and also can follow the transmission), and the conveyor belt 5 conveys the workpiece to the direction of the hinge ring 13.
The rotary transmission component can also be in another structural form;
in another example, the rotary transfer assembly includes:
referring to fig. 13, 14 and 15, a piston cylinder 81 is installed in the workbench 1, and two through holes 811 are formed at opposite corners of two side surfaces of the piston cylinder 81; the piston cylinder 81 contains fluid (such as hydraulic oil or gas with certain pressure) as driving medium.
A fluid storage tank 82 and two rotary motors 83 (the rotary motors 83 are bidirectional fixed-displacement motors) fixedly mounted on the upper ends of the piston cylinders 81, wherein the two through holes 811 are respectively and correspondingly connected with connecting ports of the two rotary motors 83 through pipelines (each rotary motor 83 is provided with two connecting ports); the other connection ports of the two rotation motors 83 are connected to the fluid storage tank 82;
a crank 85 fixedly installed on the upper end of the rotating shaft 2;
the end part of the crank 85 is connected with the end part of the driving rod of the piston cylinder 81 through a movable rod 86, one end of the movable rod 86 is hinged to the end part of the crank 85, and the other end of the movable rod 86 is hinged to the end part of the driving rod of the piston cylinder 81.
When the above-described structure is operated, the initial state is as shown in fig. 13, and whether the bending driving handle 3 is in the leftward bending process or in the rightward bending process, the process in which the driving rod of the piston cylinder 81 is driven to extend by the crank 85 corresponds to the initial state.
On the contrary, whether the bending driving handle 3 is in the return rotation process after being bent leftwards or the return rotation process after being bent rightwards, the process that the crank 85 drives the driving rod of the piston cylinder 81 to contract corresponds to the process.
Referring to fig. 16, during the fluid flow from piston cylinder 81 to fluid storage tank 82, the fluid drives rotation motor 83 to rotate clockwise; during the fluid flow from the fluid storage tank 82 to the piston cylinder 81, the fluid drives the rotation motor 83 to rotate counterclockwise (e.g., during retraction of the drive rod of the piston cylinder 81, the rotation motor 83 on the left end rotates clockwise, and the rotation motor 83 on the right side rotates counterclockwise, or vice versa).
The output shafts of the two rotating motors 83 are provided with reversing pieces 84, the upper ends of the reversing pieces 84 are connected with the conveyer belt driving wheels 51, under the action of the reversing pieces 84, the rotating motors 83 can only drive the conveyer belt driving wheels 51 to rotate in one direction, and the rotating direction is the direction in which the conveyer belt driving wheels 51 drive the conveyer belt 5 to transmit towards the output direction;
referring to fig. 17 and 18, preferably, the reversing element 84 includes an upper cover 841 rotatably nested in the housing of the workbench 1 and a lower cover 842 rotatably mounted in the upper cover 841, a ratchet mechanism is provided between the upper cover 841 and the lower cover 842, the ratchet mechanism includes a ratchet 843 provided on the upper end surface of the lower cover 842 and a pawl 844 mounted at the center of the upper cover 841, and the pawl 844 is mounted in cooperation with the ratchet 843; the cooperation between the pawl 844 and the ratchet 843 only enables the rotation motor 83 to drive the conveyer belt driving wheel 51 to rotate in a single direction, so that the rotation motor 83 is prevented from driving the conveyer belt driving wheel 51 to drive the conveyer belt 5 to convey reversely.
In addition, a wear-resistant rubber layer 845 is arranged between the upper cover 841 and the shell of the workbench 1, the wear-resistant rubber layer 845 is fixedly connected to the shell of the workbench 1, when the rotating motor 83 rotates reversely, although the ratchet 843 and the pawl 844 are not in a clamping state, due to the influence of friction force between the ratchet 843 and the pawl 844, the rotating motor 83 may drive the conveyer belt driving wheel 51 to rotate reversely to a certain degree, reverse conveying of workpieces can be brought, and by arranging the wear-resistant rubber layer 845, the friction force between the wear-resistant rubber layer 845 and the upper cover 841 is larger than the friction force between the ratchet 843 and the pawl 844, so that the conveyer belt driving wheel 51 cannot be driven to rotate by the reverse rotation of the rotating motor 83.
Under the action of the ratchet mechanism, the crank 85 drives the driving rod of the piston cylinder 81 to extend (the bending driving handle 3 is in the process of bending the workpiece), and the rotating motor 83 cannot drive the conveying belt driving wheel 51 to rotate; in the process that the crank 85 drives the driving rod of the piston cylinder 81 to contract (the bending driving handle 3 is in the reset rotation process), the rotating motor 83 on the left side drives the conveyer belt driving wheel 51 connected with the rotating motor 83 to rotate clockwise, and the rotating motor 83 on the right side drives the conveyer belt driving wheel 51 connected with the rotating motor 83 to rotate anticlockwise.
In addition, the conveying belt 5 is a rubber belt, and the rubber belt is adopted as the conveying belt 5, so that the friction force between the workpiece and the conveying belt 5 is increased, and the phenomenon that the conveying of the workpiece is influenced due to the fact that the conveying belt 5 slips due to insufficient friction force is avoided.
The clamping piece moving platform 12 is provided with two clamping seats 4 in a sliding manner, and the two clamping seats 4 are symmetrically arranged; the two clamping seats 4 are driven by a clamping driving mechanism to be switched between a clamping state and a clamping canceling state;
referring to fig. 19, the clamp driving mechanism includes:

When clamping a workpiece;
the clamping driving handle 71 is pressed downwards, the clamping driving handle 71 drives the space cam 72 to rotate, when the space cam 72 rotates, the connecting rod 77 moves along the guide groove 721, the connecting rod 77 drives the moving handle 73 to move backwards, and the triangular part 74 moving backwards drives the clamping seats 4 on the two sides to move towards the middle through the connecting convex edge 741, so that the clamping effect on the workpiece is realized.
When the workpiece is not clamped;
the clamping driving handle 71 is lifted up, the clamping driving handle 71 drives the space cam 72 to rotate, when the space cam 72 rotates, the connecting rod 77 moves along the guide groove 721, the connecting rod 77 drives the moving handle 73 to move forward, and the triangular part 74 moving forward drives the clamping seat 4 in the middle position to move to two sides through the connecting convex edge 741, so that the clamping effect is cancelled.
When the clamping structure is used, the clamping seat 4 is driven to clamp and release a workpiece by lifting or pressing down the clamping driving handle 71, and the clamping driving handle 71 adopts a lifting or pressing-down driving mode, so that the advantages of: the action of the applied force is easier to perform, and the matching degree of the driving mode and the bending part is higher and more convenient.
