When they need to be used in construction, they need to be bent to the corresponding shape before being put into use. When the plates are bent, they are usually performed on corresponding bending mechanisms. There are many types of existing bending mechanisms, and most of the bending mechanisms use transmission parts to drive the corresponding bending plates to squeeze the plates downward, drive the plates to bend on the corresponding bottom plates, and complete the bending processing operation.

[0003] However, the existing bending mechanisms have the following problems when in use:

[0028] The following will be combined with the attached embodiment of the utility model Figure 1-Figure 4 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0029] See also Figure 1-4In the embodiment of the utility model, a bending mechanism that is convenient for unloading includes a main body 1, and an upper mold structure 3 and a lower mold structure 4 are respectively provided on the upper and lower positions of the front of the main body 1. The top of the upper mold structure 3 is fixedly connected to a hydraulic mechanism 2, and the hydraulic mechanism 2 is also fixedly connected to the top of the main body 1. Guide grooves 5 are provided on both sides of the surface of the main body 1, and the upper mold structure 3 is slidably connected to the guide grooves 5. During the use of this device, the external plate is first moved along one side of the lower mold 8 in the lower mold structure 4 and the limiting plate 9 and placed on the surface of the lower mold 8, and then the bending process of the plate is realized by vertical downward pressure. During the bending process, the limiting cavity 10 in the lower mold structure 4 can effectively ensure the bending quality of the plate. After the bending is complete, the support pad 15 in the lower mold structure 4 can be used to pre-demold the bent plate to facilitate subsequent unloading operations.

[0030] In the embodiment of the utility model, the upper mold structure 3 includes a first upper mold 6 and a second upper mold 7 which are fixedly connected. The top of the first upper mold 6 is fixedly connected to the bottom end of the hydraulic mechanism 2 at the same time. The lower mold structure 4 includes a fixedly connected lower mold 8 and a limiting plate 9 on the surface of one side of its top. The surface of the lower mold 8 is also provided with a limited cavity 10. The top of the lower mold 8 is fixedly provided with a mounting groove 14. The upper mold structure 3 also includes a first spring 11, a connecting column 12 and a limiting ring 13 which are arranged in a matching manner. The limiting ring 13 is fixedly connected to the top end of the connecting column 12. The first spring 11 and the connecting column 12 are fixedly sleeved at the same time. At the same time, the first spring 11, the connecting column 12 and the limiting ring 13 are all embedded in the first upper mold 6 and the second upper mold 7. The interior of the second upper mold 7 corresponds to the connecting column 12 and is provided with a column cavity with a closed bottom. The first upper mold 6 and the second upper mold 7 are correspondingly embedded in the upper and lower positions, both of which are trapezoidal. The bottom of the second upper mold 7 is rectangular and concave. The bottom end of the connecting column 12 extends vertically to the inner side of the bottom of the second upper mold 7. At the same time, the bottom end of the connecting column 12 is fixedly sleeved with a group of rubber ring seats. The limiting ring 13 is also located in the column cavity inside the second upper mold 7. The second upper mold 7 is used to press down and bend the two ends of the external plate placed on the lower mold 8. The connecting column 12 is used to contact the surface of the external plate placed on the lower mold 8 to pre-press and position it. The first spring 11 is used to provide a boost to the connecting column 12, which assists the connecting column 12 in positioning the external plate. The limiting ring 13 is used to prevent the connecting column 12 from being demolded.

[0031] The hydraulic mechanism 2 is started, pushing the first upper mold 6 and the second upper mold 7 to descend at the same time, and the connecting column 12 at the inner side of the bottom of the second upper mold 7 first contacts the surface of the external plate on the lower mold structure 4, and as the second upper mold 7 descends, the plate is pressed downward to limit the position. Then, as the second upper mold 7 descends, the corresponding limiting openings 10 at the two end positions of the bottom of the second upper mold 7 contact the two ends of the plate, and the two ends of the plate are pressed downward to bend. During the bending process, the first spring 11 adaptively compresses and stretches according to the force condition of the connecting column 12, and assists the connecting column 12 to press the external plate downward to limit the position.

[0032] The lower mold 8 is arranged in a rectangular shape as a whole, and the limiting cavities 10 are opened vertically downward along the two sides of the top of the lower mold 8. Two groups of limiting cavities 10 are opened in parallel. The lower mold 8 and the limiting cavities 10 are arranged in a "W" shape as a whole. At the same time, the limiting cavities 10 and the two ends of the bottom of the second upper mold 7 are relatively arranged in the upper and lower positions. The lower mold 8 is used to support and place the external plate, and the limiting cavities 10 are used to limit the bending positions of the two ends of the plate.

[0033] After the plate is placed on the surface of the lower mold 8, the second upper mold 7 descends, and its two ends contact the two ends of the plate, so that the two ends of the plate are embedded in the limiting cavity 10 while being bent under force until the bending is completed. The limiting cavity 10 can effectively limit the two end positions of the bent plate to ensure the bending effect.

[0034] The lower mold structure 4 also includes a fixedly connected support pad 15 and a second spring 16, and the bottom end of the second spring 16 is fixedly connected to a mounting seat 17. The support pad 15, the second spring 16 and the mounting seat 17 are all embedded in the mounting groove 14, and the mounting groove 14 is simultaneously opened between the two groups of limiting openings 10. The support pad 15 is a trapezoidal pad arranged longitudinally, and the second spring 16 is arranged as a metal compression spring arranged vertically. The support pad 15 is used to support and place the external plate, and the subsequent plate unloading is facilitated. The second spring 16 is used to provide assistance to the support pad 15, and the support pad 15 is adaptively adjusted according to the force conditions, which is beneficial to the subsequent plate unloading.

[0035] When the external plate is placed on the lower die 8, it is also placed on the support plate 15. In the subsequent bending operation, the plate is under stress and the support plate 15 is lowered under the action of the second spring 16. At this time, the support plate 15 and the surface of the lower die 8 remain horizontal. After the bending is completed, as the second upper die 7 rises, the stress on the support plate 15 disappears, and under the action of the second spring 16, the bent plate bounces upward, making it easy for the user to quickly complete the unloading operation of the plate.

[0036] A group of vertically arranged rectangular baffles are fixedly connected to the back of the lower mold 8, and the rectangular baffles are also located on the back of the support pad 15. The limiting plate 9 is overall "L"-shaped and inverted vertically arranged, and is located on the back of one side of the lower mold 8, and is adjacent to the rectangular baffle on the back of the lower mold 8. The rectangular baffle and the limiting plate 9 on the back of the lower mold 8 can facilitate the placement of external plates on the surface of the lower mold 8.
