It should be noted that, in the process of moving the bending block 122 from the first position to the second position, the workpiece 2 is bent. When the bending block 122 is located at the first position, the workpiece 2 is not bent, and in this state, the first template 10 and the second template 12 clamp the workpiece 2, so that the workpiece 2 is fixed, and the workpiece 2 is prevented from moving in the bending process to affect the bending effect of the workpiece 2; alternatively, when the bending block 122 is in the first position, the second template 12 is located above the first template 10, and the first template 10 and the second template 12 are spaced apart from each other, so as to facilitate the taking and placing of the workpiece 2.

In a specific application, the second template 12 moves towards the first template 10, so that the bending block 122 approaches the first template 10 along with the movement of the plate body 120, when the plate body 120 of the second template 12 and the first template 10 clamp the workpiece 2, the workpiece 2 is pressed by the first template 10 and the second template 12, the bending block 122 contacts the workpiece 2, and when the second template 12 continues to move towards the first template 10, the first template 10 and the workpiece 2 push the bending block 122 to rotate, so that the bending block 122 bends the workpiece 2.

Further, the plate 120 can also be moved away from the first die plate 10 to separate the second die plate 12 from the first die plate 10, thereby facilitating the removal of the bent workpiece 2 and the placement of the workpiece 2 to be bent.

As shown in fig. 4 and fig. 6, according to the second embodiment of the present invention, on the basis of the above embodiment, further: the first template 10 is provided with a bending angle 102, the bending block 122 includes a bending groove 1220, and the bending groove 1220 is matched with the bending angle 102.

Under the condition that the bending block 122 is at the first position, the bending groove 1220 is located above the bending angle 102 along the first direction, and a part of the bending groove 1220 protrudes out of the bending angle 102 along the second direction; with the bending block 122 in the second position, the bending groove 1220 wraps around the bending corner 102, and a portion of the workpiece 2 is located between the bending groove 1220 and the bending corner 102.

In this design, the first template 10 is provided with the bending angle 102, and the bending block 122 is provided with the bending groove 1220 adapted to the bending angle 102, so that the workpiece 2 can be bent by matching the bending groove 1220 with the bending angle 102. Under the condition that the bending block 122 is located at the first position, the workpiece 2 is not bent, in this case, the bending groove 1220 is located above the bending angle 102 along the first direction, and a part of the bending groove 1220 protrudes out of the bending angle 102 along the second direction, so that the part of the bending groove 1220 protruding out of the bending angle 102 can bend the part of the workpiece 2 in a suspended state in the rotating process. When the bending block 122 is located at the second position, the workpiece 2 is bent, and in this case, the bending groove 1220 covers the bending angle 102, so that the bending groove 1220 is matched with the bending angle 102, and the workpiece 2 located between the bending groove 1220 and the bending angle 102 is bent.

It should be noted that the bending groove 1220 is adapted to the bending angle 102, that is, the bending groove 1220 and the bending angle 102 can be matched to bend the workpiece 2.

It can be understood that, along the second direction, a part of the bending groove 1220 protrudes out of the bending angle 102, and the part of the bending groove 1220 protruding out of the bending angle 102 corresponds to the suspended part of the workpiece 2, so that the first mold is prevented from interfering with the rotation of the bending block 122, the bending block 122 can rotate, and the workpiece 2 can be bent through the bending groove 1220 and the bending angle 102.

Further, the bending slot 1220 includes a first sidewall 1222 and a second sidewall 1224 connected, and the first sidewall 1222 and the second sidewall 1224 have an included angle therebetween.

It is understood that the angle between the first sidewall 1222 and the second sidewall 1224 can be set according to the actual situation, and specifically, can be set according to the bending angle of the workpiece 2. The angle between the first sidewall 1222 and the second sidewall 1224 is the same as the bending angle of the workpiece 2.

Accordingly, the bending angle 102 includes a third sidewall and a fourth sidewall, and an included angle is formed between the third sidewall and the fourth sidewall, wherein the third sidewall has a shape matching the shape of the first sidewall 1222, and the fourth sidewall has a shape matching the shape of the second sidewall 1224.

Further, the angle between the third sidewall and the fourth sidewall is the same as the angle between the first sidewall 1222 and the second sidewall 1224.

Further, the first sidewall 1222 and the second sidewall 1224 are both planar.

In this design, the first sidewall 1222 and the second sidewall 1224 are both planar, so that the bending of the bending block 122 can flatten the surface of the bent workpiece 2, thereby facilitating the assembly of the workpiece 2.

Of course, the first sidewall 1222 and the second sidewall 1224 may be curved so that the workpiece 2 after bending has a curvature.

Accordingly, the third and fourth sidewalls of the first form 10 are both planar.

Further, the first sidewall 1222 and the second sidewall 1224 are smooth and planar, thereby reducing the possibility of scratching the workpiece 2 by the first sidewall 1222 and the second sidewall 1224 when the bending block 122 is in the second position. Further, the first and second sidewalls 1222 and 1224 are coated with a lubricant.

Further, the first sidewall 1222 and the second sidewall 1224 are perpendicular.

In this embodiment, the first sidewall 1222 and the second sidewall 1224 are perpendicular, i.e., the bending groove 1220 is a right-angled bending groove 1220, so that the workpiece 2 can be bent into a right-angled flange after being bent by the bending block 122.

Accordingly, the third sidewall of the first form 10 is perpendicular to the fourth sidewall of the first form 10.

As shown in fig. 4, according to a third embodiment of the present invention, on the basis of the second embodiment, further: the bending piece 122 is provided with a flat surface 1226.

Therefore, when the second die plate 12 is moved toward the first die plate 10, the first die plate 10 pushes the bending block 122 to rotate by the flat surface portions 1226, so that the bending block 122 bends the workpiece 2. Meanwhile, the plane 1226 is in contact with the workpiece 2, so that the pressure of the contact part of the workpiece 2 and the bending block 122 is reduced, and the bending block 122 is prevented from generating an indentation on the workpiece 2.

In another possible design, planar segment 1226 is positioned above workpiece 2 when bending block 122 is in the first position. That is, when the bending block 122 is in the first position, the second template 12 is positioned above the first template 10 such that a gap is provided between the first template 10 and the second template 12, thereby facilitating the pick-and-place of the workpiece 2.

In a specific application, as shown in fig. 4 and 5, the bending block 122 is in the first position, and further, the first position includes a first sub-position and a second sub-position, and specifically, as shown in fig. 4, the bending block 122 is in the first sub-position, as shown in fig. 5, the bending block 122 is in the second sub-position, as shown in fig. 6, the bending block 122 is in the second position.

When the workpiece 2 is bent, the bending block 122 moves from the first sub-position and the second sub-position to the second position in sequence; when the second template 12 is lifted after the bending of the workpiece 2 is completed, the bending block 122 moves from the second position and the second sub-position to the first sub-position in sequence.

As shown in fig. 4, when the bending block 122 is located at the first sub-position, the workpiece 2 is not bent, and the first template 10 and the second template 12 are spaced apart from each other, so that the plane 1226 is located above the workpiece 2, that is, the bending apparatus 1 is in the open state, so as to facilitate taking and placing of the workpiece 2; as shown in fig. 5, when the bending block 122 is located at the second sub-position, the workpiece 2 is not bent, the plate 120 and the first template 10 clamp the workpiece 2, and the plane 1226 and the first template 10 clamp the workpiece 2, so that the pressure applied to the contact portion between the workpiece 2 and the bending block 122 is reduced, and the bending block 122 is prevented from leaving an impression on the workpiece 2; when the bending block 122 is in the second position, the workpiece 2 is bent, and the bending groove 1220 covers the bending angle 102, as shown in fig. 6.

Specifically, during the process of bending the workpiece 2, the second template 12 moves toward the first template 10 in the first direction, and the first template 10 and the second template 12 press the workpiece 2 (as shown in fig. 5); the first template 10 and the workpiece 2 push the bending block 122 to rotate, and the bending groove 1220 is matched with the bending angle 102, so that the process of folding and flanging the workpiece 2 is completed (as shown in fig. 6); there is no surface-to-surface sliding friction between the bending block 122 and the workpiece 2.

As shown in fig. 4 to 6, according to a fourth embodiment of the present invention, on the basis of the above embodiment, further: the plate body 120 includes: a clamping plate 1200 and a stripper plate 1202.

Specifically, the bending block 122 is rotatably connected with the clamping plate 1200, a notch is formed in the clamping plate 1200, and the notch is located on one side of the bending block 122 along the second direction; the stripper plate 1202 is disposed at the notch, and the stripper plate 1202 is movably connected with the clamp plate 1200 along the first direction.

In this design, the plate body 120 includes a clamping plate 1200 and a stripper plate 1202, the bending block 122 is rotatably connected to the clamping plate 1200, and the stripper plate 1202 is movably connected to the clamping plate 1200 along a first direction. Thus, when the second template 12 moves towards the first template 10, the clamping plate 1200 drives the stripper plate 1202 and the bending block 122 to move towards the first template 10, when the stripper plate 1202 and the first template 10 clamp the workpiece 2, the bending block 122 contacts the workpiece 2, because the stripper plate 1202 and the clamping plate 1200 are movably connected, the clamping plate 1200 can further move towards the first template 10 along the first direction, when the clamping plate 1200 continues to move towards the first template 10, the clamping plate 1200 moves relative to the stripper plate 1202, and the bending block 122 rotates under the pushing of the first template 10 and the workpiece 2, thereby completing the bending of the workpiece 2.

The clamping plate 1200 is provided with a notch, and the notch is arranged on one side of the bending block 122 along the second direction, so that the workpiece 2 can be clamped by the stripper plate 1202 and the first template 10, the interference of the stripper plate 1202 on the rotation of the bending block 122 can be avoided, and the reliability of the bending block 122 on the bending of the workpiece 2 is ensured.

In a specific application, as shown in fig. 4, the bending block 122 includes a bending slot 1220, a planar portion 1226 is disposed on a side of the bending slot 1220 near the stripper plate 1202, and the first die plate 10 includes a bending corner 102. The stripper plate 1202 and the bending block 122 are moved with the clamp plate 1200 toward the first die plate 10 such that the bending block 122 is moved to the first sub-position, the second sub-position, and the second position in sequence. As shown in fig. 4, when the bending block 122 is located at the first sub-position, the first die plate 10 is spaced apart from the second die plate 12, so that the stripper plate 1202 is spaced apart from the first die plate 10. When the bending block 122 moves from the first sub-position to the second sub-position, the stripper plate 1202 and the bending block 122 move toward the first template 10 along with the clamping plate 1200, as shown in fig. 5, when the bending block 122 is at the second sub-position, the stripper plate 1202 and the first template 10 clamp the workpiece 2 to prevent the workpiece 2 from moving during the bending process, and meanwhile, the plane portion 1226 on one side of the bending groove 1220 is pressed against the workpiece 2 to prevent the workpiece 2 from arching during the bending process; when the bending block 122 moves from the second sub-position to the second position, the stripper plate 1202 still clamps the workpiece 2 with the first template 10, so as to prevent the workpiece 2 from moving, and the clamp plate 1200 and the stripper plate 1202 move relatively to each other, so that the clamp plate 1200 continues to move towards the first template 10, and then the first template 10 and the workpiece 2 push the bending block 122 to rotate, so that the bending groove 1220 is matched with the bending angle 102, and the workpiece 2 is bent.

In one possible design, as shown in fig. 4 and 5, when the bending block 122 is in the first position, a gap is formed between the top of the stripper plate 1202 and the clamping plate 1200 along the first direction, and the bottom of the stripper plate 1202 protrudes from the clamping plate 1200; as shown in fig. 6, when the bending block 122 is in the second position, the top of the stripper plate 1202 is attached to the clamp plate 1200, and the bottom of the stripper plate 1202 and the first die plate 10 clamp the workpiece 2.

In this design, when the bending block 122 is disposed at the first position, a gap is formed between the upper portion of the stripper plate 1202 and the clamp plate 1200 along the first direction, so as to provide a movement space for the relative movement of the stripper plate 1202 and the clamp plate 1200, and the bottom of the stripper plate 1202 protrudes out of the clamp plate 1200, so that the stripper plate 1202 contacts the workpiece 2 before the clamp plate 1200 contacts the workpiece, and the clamp plate 1200 can continue to move toward the first template 10, so that the bending block 122 rotates, and the workpiece 2 is bent. When the bending block 122 is located at the second position, the top of the stripper plate 1202 is attached to the clamp plate 1200, so that the stripper plate 1202 and the clamp plate 1200 are mutually limited, the stripper plate 1202 is prevented from being detached from the clamp plate 1200, the reliability of the structure is improved, and the bottom of the stripper plate 1202 and the first template 10 clamp the workpiece 2, so that the workpiece 2 is prevented from moving.

In a particular application, the second template 12 is movable toward the first template 10. So that bending block 122 moves to the first sub-position, the second sub-position, and the second position in sequence. As shown in fig. 4 and 5, when the bending block 122 moves from the first sub-position to the second sub-position, the stripper plate 1202 and the bending block 122 move toward the first die plate 10 along with the clamp plate 1200, and in the process, the stripper plate 1202 and the clamp plate 1200 do not move relatively; as shown in fig. 5, when the bending block 122 is in the second sub-position, the stripper plate 1202 and the first template 10 clamp the workpiece 2; as shown in fig. 5 and 6, when the bending block 122 moves from the second sub-position to the second position, the gap between the stripper plate 1202 and the clamp plate 1200 gradually decreases until the tip of the stripper plate 1202 abuts against the clamp plate 1200, thereby completing the bending of the workpiece 2.

Accordingly, in the process of moving the bending block 122 from the second position to the first position, the stripper plate 1202 is gradually moved away from the clamping plate 1200 from the position where the stripper plate 1202 is attached to the clamping plate 1200, so that the gap between the stripper plate 1202 and the clamping plate 1200 is gradually increased until the bending block 122 moves to the first position.

Further, in the second direction, the rotation axis of the bending block 122 is located on the right side of the first template 10.

According to a fifth embodiment of the present invention, on the basis of the fourth embodiment, further: the clamping plate 1200 comprises an upper clamping plate 1204 and a mounting plate 1206 which are fixedly connected, the mounting plate 1206 is positioned at the bottom of the upper clamping plate 1204, the upper clamping plate 1204 is movably connected with a stripper plate 1202, and the bending block 122 is rotatably connected with the mounting plate 1206.

In this design, the clamp plate 1200 includes an upper clamp plate 1204 and a mounting plate 1206, the upper clamp plate 1204 being movably connected to the stripper plate 1202. The mounting plate 1206 is fixedly connected to the bottom of the upper clamping plate 1204, so that the clamping plate 1200 extends downward, and a mounting position is provided for the bending block 122. Meanwhile, along the second direction, the stripper plate 1202 and the mounting plate 1206 are sequentially arranged, so that when the bending device 1 bends the workpiece 2, the mounting plate 1206 can drive the bending block 122 to move towards the first template 10, and the workpiece 2 can be bent.

The clamping plate 1200 is divided into the upper clamping plate 1204 and the mounting plate 1206, so that the bending block 122 can be mounted conveniently, and the mounting difficulty of the upper clamping plate 1204 is reduced. Meanwhile, the upper clamp plate 1204 is fixedly connected with the mounting plate 1206, so that in the process that the upper clamp plate 1204 moves towards the first template 10, the bending block 122 and the mounting plate 1206 can move towards the first template 10 along with the movement of the upper clamp plate 1204, and further when the bending block 122 is in contact with the workpiece 2, the first template 10 and the workpiece 2 can push the bending block 122 to rotate, so that the workpiece 2 can be bent.

Further, the upper clamp plate 1204 and the mounting plate 1206 are of an integrated structure, so that the connection strength between the upper clamp plate 1204 and the mounting plate 1206 is guaranteed, and the mounting plate 1206 is prevented from falling off from the upper clamp plate 1204 in the bending process.

In some possible designs, the mounting plate 1206 is provided with a clearance portion, and the clearance portion is located at the bottom of the mounting plate 1206 along the first direction, and the clearance between the stripper plate and the upper clamp plate 1204 is the same as the height of the clearance portion.

In this design, the mounting plate 1206 is further provided with a clearance portion, which is provided at the bottom of the mounting plate 1206, and the clearance between the upper clamp plate and the stripper plate 1202 is the same as the height of the clearance portion along the first direction. Thus, when the bending block 122 moves from the first position to the second position, the bottom of the mounting plate is also in contact with the workpiece 2, so that the position of the workpiece 2 cannot be changed, and the bending effect of the workpiece 2 is ensured.

According to a sixth embodiment of the present invention, on the basis of the fourth embodiment, further: the stripper plate 1202 is slidably connected to the clamp plate 1200.

In this design, the stripper plate 1202 and the clamp plate 1200 are slidably coupled, which reduces the sliding friction between the stripper plate 1202 and the clamp plate 1200, thereby reducing the wear of the stripper plate 1202 and the clamp plate 1200 and increasing the service life of the second die plate 12.

When the bending block 122 bends the workpiece 2, the stripper plate 1202 and the clamp plate 1200 slide relatively, so that the movement resistance of the clamp plate 1200 is reduced.

It will be appreciated that the stripper plate 1202 is slidably coupled to the clamp plate 1200 in a first direction.

In some possible designs, the stripper plate 1202 and the clamp plate 1200 are slidably coupled by a slide rail.

In the design, the stripper plate 1202 and the clamp plate 1200 are slidably connected through the slide rails, so that the stripper plate 1202 can slide more smoothly with the slide rails, and the reliability of connection between the stripper plate 1202 and the clamp plate 1200 is also ensured.

In a specific application, a sliding groove is arranged on one of the stripper plate 1202 and the clamp plate 1200, and a sliding block is arranged on the other of the stripper plate 1202 and the clamp plate 1200, and the sliding block is arranged in the sliding groove and can slide in the sliding groove.

Wherein, the sliding groove extends along the first direction, so that the sliding block can slide along the first direction in the sliding groove, and further the stripper plate 1202 slides along the first direction relative to the clamp plate 1200.

As shown in fig. 4 to 5, according to a seventh embodiment of the present invention, on the basis of the fourth embodiment, further: the second template 12 further comprises: the first elastic member 124.

The first elastic member 124 connects the stripper plate 1202 and the clamp plate 1200, and when the bending block 122 is at the second position, the first elastic member 124 is in a deformed state.

In this design, as shown in fig. 4, the second mold plate 12 further includes a first elastic member 124, the first elastic member 124 is connected to the stripper plate 1202 and the clamping plate 1200, so as to reset the stripper plate 1202, wherein when the bending block 122 moves to the second position, the first elastic member 124 is in a deformed state, so that after the second mold plate 12 is lifted, the clamping plate 1200 moves upward, the first elastic member 124 recovers the deformation, and the stripper plate 1202 is driven to move downward in the first direction, so that the stripper plate 1202 resets.

In a specific application, the first elastic member 124 is a spring.

In some possible designs, the first elastic member 124 is connected to the clamping plate 1200 by a first connecting member.

In this design, the first elastic member 124 is connected to the clamping plate 1200 by the first connecting member, which improves the reliability of the connection between the first elastic member 124 and the clamping plate 1200.

In a specific application, the first connecting member is a bolt or a screw, so that the first elastic member 124 is detachably connected with the clamping plate 1200.

In some possible designs, the first elastic member 124 is connected to the stripper plate 1202 by bolts or screws, so that the first elastic member 124 is detachably connected to the stripper plate 1202.

As shown in fig. 4 to 6, during the process of bending the workpiece 2 by the bending apparatus 1, the stripper plate 1202 and the clamp plate 1200 slide relatively to each other, so that the first elastic member 124 is gradually compressed; after the bending is completed and the second mold plate 12 is lifted, the first elastic member 124 is deformed again, and the stripper plate 1202 is reset by the driving of the first elastic member 124.

Specifically, a first end of the first elastic member 124 is connected to the upper clamping plate 1204, and a second end of the first elastic member 124 is connected to the stripper plate 1202.

As shown in fig. 4 to 6, according to the eighth embodiment of the present invention, on the basis of the fourth embodiment, further: the second template 12 further comprises: and a second elastic member 126.

The second elastic member 126 connects the bending block 122 and the plate body 120, and when the bending block 122 is at the second position, the second elastic member 126 is in a deformed state.

In this design, the second form 12 further includes a second elastic member 126, and the second elastic member 126 is connected to the bending block 122 and the plate body 120 to achieve the resetting of the bending block 122. When the bending block 122 is in the second position, the second elastic member 126 is in a deformed state, and therefore when the second template 12 is lifted upwards, the bending block 122 is separated from the bending angle 102, the second elastic member 126 is deformed again, and the bending block 122 is reset under the driving of the second elastic member 126.

In a specific application, the second elastic member 126 is a spring.

In some possible designs, the second elastic member 126 is connected to the bending block 122 by a second connecting member.

In some possible designs, the connection point of second resilient element 126 to bending block 122 is located outside the axis of rotation of bending block 122.

In the design, the connection point of the second elastic element 126 and the bending block 122 is located outside the rotation axis of the bending block 122, so that the second elastic element 126 can be elastically deformed along with the rotation of the bending block 122, and the bending block 122 can be ensured to be reset under the driving of the second elastic element 126 at the second position.

In a particular application, the second connector includes a bolt, such that the second connector is removably coupled to the bending block 122.

Further, the second elastic member 126 is detachably coupled to the clamping plate 1200 by a bolt or a screw.

The bending process of the whole bending device 1 is as follows: the first template 10 and the second template 12 are closed, the stripper plate 1202 and the first template 10 press the workpiece 2, and the first template 10 and the workpiece 2 push the bending block 122 to rotate, so as to complete the bending process of the workpiece 2. In the bending process, there is no surface-to-surface sliding friction between the bending block 122 and the workpiece 2, and then the second template 12 is lifted, and the bending block 122 is subjected to the pulling force of the second elastic member 126, and the resetting is completed under the action of the pulling force. By using the bending block 122 which is movable in a rotating manner, frictional sliding in the bending process in the related art is eliminated, and the problems of scratch damage on the surface of the workpiece 2 and large abrasion of the insert of the first template 10 are solved.
