Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a sheet metal bending device. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing techniques. They are indispensable in our daily lives. Sheet metal bending is a major process in sheet metal manufacturing. After bending, the sheet metal undergoes welding, painting, and other processes to ultimately become product components. They are commonly found in the production of door frames, window frames, and electrical control cabinet housings. Due to differences in their application scenarios and connection relationships, different types and shapes of bent sheet metal parts are needed to meet various usage requirements.

[0003] In existing sheet metal bending processes, when using bending robots, the sheet metal usually needs to be picked up from the loading table and transferred to the bending table. Then, the bending robot performs precise positioning and bending operations on the bending table. In the entire automatic bending process, the robot needs to perform pick-up and place operations on the loading table and the bending table respectively. Moreover, the next sheet metal can only be processed after the loading, centering and bending of one sheet metal are completed. The device cannot work continuously, and the robot's operation time is slow, resulting in very low sheet metal bending processing efficiency. Utility Model Content

[0004] In order to solve the above-mentioned technical problems existing in the prior art, this utility model provides a sheet metal bending device.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] This utility model provides a sheet metal bending device, including a feeding assembly, a conveying assembly, a suction assembly, and a positioning assembly; one end of the conveying assembly is located above the feeding assembly, and the other end is located above the positioning assembly, and the suction assembly moves along the conveying assembly; the suction assembly includes a lifting mechanism and a suction mechanism connected together, and the suction mechanism is used to suction sheet metal; the positioning assembly includes a deflection mechanism and a positioning table connected together, and a limiting member is provided on the positioning table.

[0007] The sheet metal bending device provided by this utility model can pre-align and position the sheet metal through a positioning table. When the bending robot picks up the sheet metal part for bending operation, the device can continue to load, transport, and center and position the next sheet metal part, thereby improving the efficiency of sheet metal bending processing and realizing continuous operation of the device.

[0008] Based on the above technical solution, the present invention can also be improved in the following ways:

[0009] Furthermore, the limiting member includes a first limiting member and a second limiting member, which are not arranged in parallel.

[0010] Furthermore, the first limiting member and the second limiting member are arranged perpendicularly, and the first limiting member and the second limiting member are respectively located at the two ends of the positioning platform.

[0011] The beneficial effect of adopting the above-mentioned further technical solution is that the centering and positioning of the sheet metal part can be achieved through the first limiting member and the second limiting member.

[0012] Furthermore, the positioning platform has a first position or a second position. In the first position, the positioning platform is horizontally positioned, and in the second position, the positioning platform has an angle of 130-160 degrees with the horizontal plane.

[0013] Furthermore, in the second position, the angle between the positioning platform and the horizontal plane is 145.5 degrees.

[0014] The beneficial effects of adopting the above-mentioned further technical solution are as follows: when the positioning table is in the first position, it makes room for the sheet metal parts to be transported, so that the suction mechanism can grab the sheet metal parts and move them above the positioning table; after the suction mechanism is released and the sheet metal parts fall onto the centering table, the positioning table changes to the second position, that is, the positioning table is tilted, and the sheet metal parts are centered and positioned by the limiting parts, which makes it easier for the bending robot to grab the sheet metal parts for bending operations.

[0015] Furthermore, it also includes a frame, on which the conveying assembly is disposed, and the conveying assembly includes guide rails.

[0016] Furthermore, the suction component is slidably connected to the guide rail.

[0017] The beneficial effect of adopting the above-mentioned further technical solution is that it facilitates the conveying of sheet metal parts between the feeding assembly and the positioning assembly.

[0018] Furthermore, the positioning platform is equipped with a rolling element.

[0019] The beneficial effects of adopting the above-mentioned further technical solution are: it facilitates the smooth sliding of sheet metal parts on the positioning table and prevents sheet metal parts from getting stuck on the positioning table, thus affecting the efficiency of sheet metal bending processing.

[0020] Furthermore, the feeding assembly includes a feeding platform, which is arranged horizontally, and a plurality of limiting rods are provided vertically along the upper edge of the feeding platform, with the plurality of limiting rods located at both ends of the feeding platform.

[0021] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the limiting rod ensures the neat stacking of the sheet metal parts, ensures the accuracy of the suction mechanism when picking up the sheet metal parts, and avoids misalignment.

[0022] Furthermore, this also includes bending robots.

[0023] Compared with the prior art, the present invention has the following technical effects:

[0024] The sheet metal bending device provided by this utility model has a positioning table that can be deflected. Through the limiting effect of the limiting parts on both sides of the positioning table, the sheet metal parts can be pre-centered and positioned. When the bending robot picks up the sheet metal parts for bending operations, the device can continue to load, transport, and center the next sheet metal part, realizing uninterrupted continuous operation of the device and thus improving the efficiency of sheet metal bending processing.

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0030] See Figures 1-2A sheet metal bending device includes a frame 5, on which a conveying assembly 2 is mounted. It also includes a loading assembly 1, a suction assembly 3, a positioning assembly 4, and a bending robot. One end of the conveying assembly 2 is positioned above the loading assembly 1, and the other end is positioned above the positioning assembly 4, for conveying sheet metal parts between the loading assembly 1 and the positioning assembly 4. The suction assembly 3 moves along the conveying assembly 2; when it moves above the loading assembly 1, it suctions the sheet metal parts already placed on the loading assembly 1, then moves above the positioning assembly 4, releasing and placing the sheet metal parts onto the positioning assembly 4. The suction assembly 3 includes a connected lifting mechanism 31 and a suction mechanism 32, the suction mechanism 32 being used to suction... The lifting mechanism 31 enables the lifting mechanism 32 to rise and fall, facilitating the picking, conveying, and placing of sheet metal parts. The positioning assembly 4 includes a deflection mechanism 41 and a positioning platform 42 connected together. The positioning platform 42 is provided with a limiting member 43, which includes a first limiting member 431 and a second limiting member 432 arranged vertically. The first limiting member 431 and the second limiting member 432 are respectively located at the two ends of the positioning platform 42. Specifically, the positioning platform 42 is a square plate, and the first limiting member 431 and the second limiting member 432 are respectively located on the two sides of the upper surface of the square plate. The deflection mechanism 41 is connected to the lower surface of the square plate to realize the deflection of the positioning platform 42.

[0031] The deflection mechanism 41 controls the positioning platform 42 to have a first position or a second position. When the suction mechanism 32 is above the feeding assembly 1 to grab the sheet metal part, the positioning platform 42 is in the first position, that is, the positioning platform 42 is set horizontally to make room for the suction mechanism 32 to move, and at the same time facilitates the subsequent placement of the sheet metal part on it. The suction mechanism 32 grabs the sheet metal part and moves it along the conveying assembly 2 to the top of the positioning platform 42. The lifting mechanism 31 controls the suction mechanism 32 to make the sheet metal part and the positioning platform 42 parallel. The suction mechanism 32 releases air, and the sheet metal part falls onto the positioning platform 42. After being sensed by gravity, the positioning platform 42 deflects to the second position, that is, the angle between the positioning platform 42 and the horizontal plane is 145.5 degrees. The sheet metal part is positioned by the limiting action of the first limiting member 431 and the second limiting member 432 on both sides of the positioning platform 42, which makes it easier for the bending robot to grab the sheet metal part for bending operation, and at the same time ensures more accurate bending dimensions.

[0032] The first limiting member 431 and the second limiting member 432 are limiting strip plates, which are fixed to the two sides of the positioning table 42 by bolts. When the suction mechanism 32 carries the sheet metal part to the top of the positioning table 42, the suction mechanism 32 releases the sheet metal part, and the sheet metal part slides down onto the positioning table 42 by gravity. The positioning table 42 deflects to the second position, and the sheet metal part slides on the positioning table 42. The first limiting member 431 and the second limiting member 432 stop and limit the sheet metal. The limiting members ensure that each identical sheet metal part can stop at a fixed position. The bending robot's manipulator only needs to come to the same position on the positioning table 42 each time to ensure that it can grasp the same position of each sheet metal part, thus achieving the centering and positioning of the manipulator.

[0033] The positioning table 42 is provided with a rolling element 44, which is a ball bearing embedded in the upper surface of the positioning table 42 and protruding from the surface of the positioning table 42. This facilitates the smooth sliding of the sheet metal part on the positioning table 42 and prevents the sheet metal part from getting stuck on the positioning table 42, thus affecting the sheet metal bending processing efficiency.

[0034] The feeding assembly 11 includes a feeding platform 11 and a feeding rack 13. The feeding platform 11 is installed on the feeding rack 13. The feeding platform 11 is arranged in a horizontal direction. Several limiting rods 12 are provided vertically along the upper edge of the feeding platform 11. The limiting rods 12 are located at both ends of the feeding platform 11. When multiple sheet metal parts are stacked and placed on the feeding platform 11, the limiting rods 12 ensure that the stacked sheet metal parts are neatly stacked, thereby ensuring the accuracy of the suction mechanism when picking up the sheet metal parts and avoiding misalignment. The bottom of the feeding rack 13 is equipped with sliding wheels. The feeding rack 13 can be manually pushed to achieve directional movement, thereby facilitating the picking up of sheet metal parts when the suction mechanism 32 is above the feeding assembly 1.

[0035] The conveying component 2 includes a linear guide rail, and the suction component 3 is slidably connected to the linear guide rail, facilitating the conveying of sheet metal parts between the loading component 1 and the positioning component 4. The lifting mechanism 31 is a linear cylinder used to raise and lower the suction mechanism 32, facilitating the gripping, moving, and placing of sheet metal parts. The deflection mechanism 41 is a deflection cylinder, which, through the deflection of the positioning table 42 and in cooperation with the limiting component 43, achieves pre-centering and positioning of the sheet metal parts, which is beneficial for the bending operation of the bending robot. The suction mechanism 32 is a pneumatic suction cup, magnetic suction cup, or other structural suction cup, which increases the suction force when gripping sheet metal parts, making it easier to grip larger and heavier sheet metal parts as well as small-sized and irregularly shaped sheet metal parts, improving the stability of gripping, and facilitating disassembly and replacement.

[0036] The sheet metal bending device provided by this utility model has a positioning table 42 that can be deflected. Through the limiting action of the limiting members 43 on both sides of the positioning table 42, the pre-centering and positioning of the sheet metal parts can be achieved. When the bending robot grabs the sheet metal parts for bending operations, the device can continue to load, transport, and center the next sheet metal part. That is, the bending work and centering and positioning of the bending robot can be carried out simultaneously, realizing uninterrupted continuous operation of the device, thereby improving the efficiency of sheet metal bending processing. When used with the suction mechanism 32, it can grab sheet metal parts of different sizes, shapes, and weights, and is suitable for grabbing a variety of sheet materials, with a wide range of applications.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
