Description

Technical Field

[0001] This utility model relates to a bending device for an L-shaped metal connecting plate, belonging to the field of bending machine technology. Background Technology

[0002] Bending is a crucial step in the manufacturing of L-shaped metal connecting plates, as its quality directly impacts subsequent processes and the overall product quality. Bending machines primarily consist of a base, upper die, lower die, and hydraulic mechanism. During bending, the inner surface of the bent portion of the workpiece undergoes compressive deformation, while the outer surface undergoes tensile deformation. Existing technologies, such as the bending machine disclosed in patent application CN202321864000.7, utilize cylinders, an upper bending die, and a lower bending die to bend sheet metal. Positioning holes and balls allow for precise positioning of the guide plate, enabling accurate control of the upper bending die's position. This avoids the problem of unnecessary movement of the upper bending die caused by using scale lines to control the guide plate's stroke in existing technologies.

[0003] The disadvantage of the aforementioned bending machine is that the loading and unloading of workpieces is inconvenient during the operation before and after bending. To address this, we have designed a bending device for an L-shaped metal connecting plate. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending device for an L-shaped metal connecting plate, comprising a bending outer shell, two feeding tracks, a feeding seat, and three bending drive cylinders. The two feeding tracks are bolted to the bottom end of the bending outer shell, the feeding seat is movably disposed above the two feeding tracks via a drive block, and the three bending drive cylinders are bolted to the top end of the bending outer shell.

[0006] The bending housing has a coupling plate inside, which is connected to the output ends of the three bending drive cylinders. The bottom end of the coupling plate has three bending connecting rods, and the bottom end of each of the three bending connecting rods is equipped with a cutter head mounting seat. Each cutter head mounting seat has a bending cutter head installed at its bottom end. A bending die table is installed on the horizontal plate of the feeding seat. The top of the bending die table has three bending dies that correspond one-to-one with the bending cutter heads. The top of each of the three bending dies has an L-shaped bending die.

[0007] In the above-mentioned bending device for an L-shaped metal connecting plate, material seat limiting blocks are installed on both sides of the bottom of the inner cavity of the bending outer shell, and the two material seat limiting blocks are engaged with the two ends of the horizontal plate of the feeding seat.

[0008] In the bending device for an L-shaped metal connecting plate described above, two buffer brackets are installed at the bottom of the feeding seat horizontal plate. Each of the two buffer brackets has a shock-absorbing foot and a movable caster installed at its bottom end. The shock-absorbing foot and the movable caster are flush with the ground.

[0011] In the above-mentioned bending device for an L-shaped metal connecting plate, the vertical plate of the feeding seat corresponds to the opening of the bending housing and the vertical plate can form a sealed connection with the opening.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model discloses a bending device for an L-shaped metal connecting plate. Two feeding tracks are bolted to the bottom of the bending housing. A feeding seat is movably positioned above the two feeding tracks via a drive block. A bending die table with three bending dies is located at the horizontal plate of the feeding tracks.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for a bending device for an L-shaped metal connecting plate:

[0021] Example: The bending device includes a bending housing 1, two feeding tracks 2, a feeding seat 3, and three bending drive cylinders 4. The two feeding tracks 2 are bolted to the bottom of the bending housing 1. The feeding seat 3 is movably mounted on the upper part of the two feeding tracks 2 via a drive block. The three bending drive cylinders 4 are bolted to the top of the bending housing 1.

[0022] The bending housing 1 has a coupling plate 5 inside, which is connected to the output end of three bending drive cylinders 4. The bottom end of the coupling plate 5 has three bending connecting rods 6, and the bottom end of each of the three bending connecting rods 6 is equipped with a cutter head mounting seat 7. The bottom end of each cutter head mounting seat 7 is equipped with a bending cutter head 8. The horizontal plate of the feeding seat 3 is equipped with a bending die table 9. The top of the bending die table 9 is equipped with three bending dies 10 that correspond one-to-one with the bending cutter heads 8. The top of each of the three bending dies 10 is provided with an L-shaped bending die 11.

[0023] Furthermore, in order to ensure that the horizontal plate of the feeding seat 3 slides firmly and stably into the inner cavity of the bending outer shell 1, material seat limiting blocks 13 are installed on both sides of the bottom of the inner cavity of the bending outer shell 1, and the two material seat limiting blocks 13 are engaged with the two ends of the horizontal plate of the feeding seat 3.

[0024] The feeding seat 3 also includes a vertical plate, which corresponds to the opening of the bent outer shell 1 and can form a sealed connection with the opening.

[0025] Furthermore, in order to facilitate the better movement of the feeding seat 3 along the feeding track 2, and at the same time to have a good shock absorption effect at the bottom when bending, two buffer brackets 14 are installed at the bottom of the horizontal plate of the feeding seat 3. Each of the two buffer brackets 14 is equipped with a shock-absorbing foot 15 and a movable caster 16 at the bottom end. The shock-absorbing foot 15 and the movable caster 16 are flush with the ground.

[0026] Example 2: Each bending die 10 is provided with a limit clamp 12 at its top end, and each limit clamp 12 is provided with an insertion foot 17 at its bottom end; each insertion foot 17 is inserted into the inner cavity of the bending die 10 and connected to a magnetic suction seat 18, and each limit clamp 12 is provided with a slide rail 19 in the middle.

[0027] The above scheme can limit the vertical and horizontal movement of the metal connecting plate, but does not affect the movement of the metal connecting plate along the bending die 10. This facilitates the limiting of the bent metal connecting plate and prevents the metal connecting plate from shifting during the bending process.

[0028] Working principle: The feeding seat 3 moves along the feeding track 2, conveying the three bending dies 1 carrying the metal connecting plate to the inner cavity of the bending outer shell 1. The metal connecting plate corresponds to the L-shaped bending die 11, and the longer part of the metal connecting plate is connected to the slide 19 of the limiting clamp 12. The insert pin 17 is inserted into the inner cavity of the bending die 10 and connected to the magnetic suction seat 18 to ensure the firmness of the limit. The three bending drive cylinders 4 synchronously drive the three bending cutter heads 8 to bend the metal connection to form an L-shaped structure.

[0029] In this solution, a track feeding method is adopted, which makes it easy to drive the bending die table 9 to correspond to the bottom of the bending cutter 8 to realize the bending operation. At the same time, it is convenient to remove the bent workpiece.
