For example, without departing from the scope of this application, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0037] It should be noted that in different drawings, the same reference numerals denote the same or substantially the same components.

[0038] like Figure 1 As shown, a bending tool according to a preferred embodiment of the utility model is used to perform a bending operation on a component to be bent 4. The bending tool comprises: a seat body 1, a clamping and positioning mechanism 2 and an extrusion assembly 3.

[0039] The component to be bent 4 includes a cover plate 41 and a connecting piece 42 . The connecting piece 42 includes a first portion 421 and a second portion 422 . The first portion 421 is connected to the second portion 422 , and the first portion 421 is connected to the cover plate 41 .

[0040] The seat body 1 has a mounting surface. The clamping and positioning mechanism 2 includes: a fixed seat 21 and a moving assembly 22. The extrusion assembly 3 includes: a driving mechanism 31 and a push block 32.

[0041] The fixed seat 21 and the moving assembly 22 are arranged on the mounting surface of the seat body 1 at intervals along the first direction X, and the fixed seat 21 is movably connected with the moving assembly 22. A gap 5 is formed between the fixed seat 21 and the moving assembly 22, and the gap 5 is used to accommodate the first part 421, and the second part 422 is away from the seat body 1 and protrudes from the gap 5.

[0042] The extrusion assembly 3 includes a driving mechanism 31 and a pushing block 32. The driving mechanism 31 is connected to the pushing block 32. The driving mechanism 31 is used to drive the pushing block 32 to move along the first direction X, close to the extrusion second part 422, so as to bend the second part 422 and the first part 421 at a preset angle.

[0043] Based on the above structure, the fixed seat 21 of the present application is installed on the mounting surface of the seat body 1. When the bending part 4 needs to be bent, the moving assembly 22 is first driven to move the moving assembly 22 away from the fixed seat 21, so that there is a gap 5 between the moving assembly 22 and the fixed seat 21 for placing the part 4 to be bent. Then, the moving assembly 22 is driven to move the moving assembly 22 close to the fixed seat 21 so that the moving assembly 22 and the fixed seat 21 clamp the first part 421 of the part 4 to be bent between the fixed seat 21 and the moving assembly 22, and then the driving mechanism 31 drives the pushing block 32 along the first part 421 of the part 4 to be bent. Move in a direction X, because the first part 421 of the part 4 to be bent is fixed in the gap 5 at this time, the push block 32 can bend the second part 422 and the first part 421 to a preset angle by squeezing the second part 422, and finally remove the push block 32 through the driving mechanism 31 and drive the moving assembly 22 through the handle 2216 to make the moving assembly 22 away from the fixed seat 21, so that the moving assembly 22 and the fixed seat 21 are separated from the clamping of the first part 421 of the part 4 to be bent, thereby achieving the bending of the first part 421 and the second part 422 of the part 4 to be bent. The present application uses the clamping positioning mechanism 2 and the squeezing assembly 3 to replace manual bending of the part 4 to be bent, thereby reducing the labor intensity of the staff, and the bending tooling of the present application is easy to operate, and can ensure the consistency of each part 4 to be bent after bending.

[0044] It is understandable that there are various ways of active connection between the fixing base 21 and the moving component 22 of the present application, which are not specifically limited here. An embodiment of the moving component 22 is given below as an example.

[0045] In a possible embodiment of the moving assembly 22, the moving assembly 22 includes: a pushing mechanism 221 and a moving seat 222. The pushing mechanism 221 is connected to the moving seat 222, and is used to push the moving seat 222 to approach or move away from the fixed seat 21 along the first direction X. When the moving seat 222 approaches the fixed seat 21 along the first direction X, the first part 421 is clamped between the fixed seat 21 and the moving seat 222. When the moving seat 222 moves away from the fixed seat 21 along the first direction X, the first part 421 is released from the clamping of the fixed seat 21 and the moving seat 222.

[0046] Further, the push mechanism 221 includes: a mounting plate 2211, a sleeve 2212, a sliding shaft 2213, a first hinge block 2214, a second hinge block 2215 and a handle 2216. The mounting plate 2211 is arranged on the seat body 1. The sleeve 2212 is arranged on the mounting plate 2211. The sliding shaft 2213 is slidably arranged in the sleeve 2212 along the first direction X. One end of the first hinge block 2214 is hinged to the first end of the sliding shaft 2213, and the other end of the first hinge block 2214 is hinged to the first end of the second hinge block 2215. The second end of the second hinge block 2215 is hinged to the mounting plate 2211 through a rotating shaft. The second end of the sliding shaft 2213 is connected to the movable seat 222. The handle 2216 is connected to the second hinge block 2215, and the handle 2216 is used to drive the second hinge block 2215 to rotate relative to the rotating shaft.

[0047] Based on the above structure, when the present application needs to drive the movable seat 222 to approach the fixed seat 21, the present application swings the handle 2216 to make the first end of the second hinge block 2215 rotate around the second end, so that the first end of the second hinge block 2215 swings close to the fixed seat 21, and then drives the first hinge block 2214 and the sliding shaft 2213 to move toward the fixed seat 21, and then drives the movable seat 222 to move toward the fixed seat 21 so as to press the part 4 to be bent between the fixed seat 21 and the movable seat 222. When the present application needs to drive the movable seat 222 away from the fixed seat 21, the present application swings the handle 2216 to make the first end of the second hinge block 2215 rotate around the second end, so that the first end of the second hinge block 2215 swings away from the fixed seat 21, and then drives the first hinge block 2214 and the sliding shaft 2213 to move away from the fixed seat 21, and then drives the movable seat 222 to move away from the fixed seat 21.

[0048] Based on this, the present application can drive the movable seat 222 to move relative to the fixed seat 21, so as to achieve the clamping and loosening of the first part 421 of the component 4 to be bent.

[0049] Specifically, the sleeve 2212 extends along the first direction X, so that the sliding shaft 2213 can move along the first direction X.

[0050] In a possible embodiment of the clamping and positioning mechanism 2, the clamping and positioning mechanism 2 also includes: a clamping portion 23. A receiving groove 211 adapted to the cover plate 41 is provided on the side of the fixed seat 21 facing the movable component 22, and the clamping portion 23 is movably provided on the side of the movable seat 222 facing the fixed seat 21 along the second direction Y. The gap 5 is located between the clamping portion 23 and the fixed seat 21. Among them, the part 4 to be bent is clamped between the clamping portion 23 and the fixed seat 21. The present application adjusts the position of the clamping portion 23 on the fixed seat 21 along the second direction Y so as to be compatible with cover plates 41 of different specifications.

[0051] Specifically, the clamping portion 23 has a first supporting surface for supporting the second part 422 on the side facing away from the seat body 1, so that the clamping portion 23 can be used to clamp the part to be bent 4 between the clamping portion 23 and the fixed seat 21 on the one hand, and can support the second part 422 of the part to be bent 4 on the other hand.

[0052] Furthermore, the clamping and positioning mechanism 2 also includes: a first fastener 24. The clamping portion 23 is provided with a first slide groove 231 extending along the second direction Y, the movable seat 222 is provided with a first mounting hole 2221, the first fastener 24 is inserted into the first slide groove 231 and the first mounting hole 2221, and the present application adjusts the relative position of the clamping portion 23 and the movable seat 222 in the second direction Y by sliding the first fastener 24 in the first slide groove 231. And / or, the clamping portion 23 is provided with a second mounting hole, the movable seat 222 is provided with a second slide groove extending along the second direction Y, the first fastener 24 is inserted into the second slide groove and the second mounting hole, and the present application adjusts the relative position of the clamping portion 23 and the movable seat 222 in the second direction Y by sliding the first fastener 24 in the second slide groove.

[0053] It is understandable that the first fastener 24 of the present application has various embodiments, which are not limited here. For example, the first fastener 24 can be a bolt and a nut, that is, the pressing part 23 and the moving seat 222 are clamped by the nut and the head of the bolt.

[0054] In a possible embodiment, the clamping and positioning mechanism 2 further includes: a first guide rod 25. The fixed seat 21 is provided with a first guide hole extending along the first direction X. The first guide rod 25 is inserted into the first guide hole and connected to the movable seat 222. The first guide rod 25 and the first guide hole can guide the movable seat 222 so that the movable seat 222 can only move along the first direction X, so as to avoid the movable seat 222 from shifting during operation, thereby resulting in a situation where the workpiece to be bent cannot be clamped between the movable seat 222 and the fixed seat 21.

[0055] In a possible embodiment, the driving mechanism 31 includes: a pneumatic cylinder, a hydraulic cylinder or an oil cylinder. The output shaft of the driving mechanism 31 is fixedly connected to the pushing block 32. The driving mechanism 31 is used to drive the pushing block 32 to move along the first direction X.

[0056] It is understandable that the driving mechanism 31 in the embodiment of the utility model only needs to realize driving the push block 32 to push along the first direction X, and no limitation is made here. For example, it can also be in the form of a linear guide rail.

[0057] Furthermore, the embodiment of the utility model further includes: a second guide rod 6. A second guide hole extending along the first direction X is provided on the fixing seat 21. The second guide rod 6 is inserted into the second guide hole and connected to the push block 32. The second guide rod 6 and the second guide hole can guide the push block 32 so that the push block 32 can only move along the first direction X, so as to avoid the push block 32 from shifting during operation, thereby causing the first part 421 and the second part 422 of the workpiece to have inconsistent angles.

[0058] In a possible embodiment, a chamfer 321 is provided on the push block 32. The chamfer 321 is provided at the junction of the side of the push block 32 away from the driving mechanism 31 and the side close to the seat body 1. The junction of the side of the push block 32 away from the driving mechanism 31 and the side close to the seat body 1 is the position in contact with the part 4 to be bent. The junction is used to push the part 4 to be bent so that the first part 421 and the second part 422 are bent. The chamfer 321 is provided at the junction to avoid stress concentration when contacting the part 4 to be bent, thereby avoiding the situation where the part 4 to be bent breaks, and can effectively protect the part 4 to be bent.

[0059] In a possible embodiment, the utility model embodiment further includes: a positioning block 7 and a second fastener. The positioning block 7 is located in the gap 5. The positioning block 7 is provided with a third slide groove 71 extending along the second direction Y, the fixed seat 21 is provided with a third mounting hole 212, and the second fastener is penetrated through the third slide groove 71 and the third mounting hole 212. Based on this, the positioning block 7 of the present application is used to support the cover plate 41 of the component 4 to be bent. The present application slides in the third slide groove 71 through the second fastener to adjust the relative position of the positioning block 7 and the fixed seat 21 in the second direction Y. And / or, the positioning block 7 is provided with a fourth mounting hole, the fixed seat 21 is provided with a fourth slide groove extending along the second direction Y, and the second fastener is penetrated through the fourth slide groove and the fourth mounting hole. Based on this, the positioning block 7 of the present application is used to support the cover plate 41 of the component 4 to be bent. The present application slides in the fourth slide groove through the second fastener to adjust the relative position of the positioning block 7 and the fixed seat 21 in the second direction Y.

[0060] It is understandable that the second fastener of the present application has multiple implementations, which are not limited here. For example, the second fastener can be a bolt and a nut, that is, the fixing seat 21 and the positioning block 7 are clamped by the nut and the head of the bolt.

[0061] The working process of the utility model is as follows: when the bending part 4 needs to be bent, the handle 2216 is first swung to make the first end of the second hinge block 2215 rotate around the second end, so that the first end of the second hinge block 2215 is swung close to the fixed seat 21, and then the first hinge block 2214 and the sliding shaft 2213 are driven to move toward the fixed seat 21, and then the movable seat 222 is driven to move toward the fixed seat 21 to press the part 4 to be bent between the fixed seat 21 and the movable seat 222, and then the push block 32 is driven by the cylinder to move along the first direction X. At this time, the first part of the part 4 to be bent The second part 421 is fixed in the gap 5, and the second part 422 is squeezed at the joint position of the side of the push block 32 away from the driving mechanism 31 and the side close to the seat body 1 to bend the second part 422 and the first part 421 to a preset angle, and finally the push block 32 is removed by the cylinder and the handle 2216 is swung to rotate the first end of the second hinge block 2215 around the second end, so that the first end of the second hinge block 2215 is swung away from the fixed seat 21, and then the first hinge block 2214 and the sliding shaft 2213 are driven to move back to the fixed seat 21, and then the moving seat 222 is driven to move back to the fixed seat 21. The present application uses the clamping positioning mechanism 2 and the extrusion assembly 3 to replace the manual bending of the bending component 4, thereby reducing the labor intensity of the staff, and the bending tooling of the present application is easy to operate and can ensure the consistency of each bending component 4 after bending.

[0062] The above are only preferred implementations of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
