Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figures 1 to 6 This utility model provides a technical solution: a stable sheet metal bending device, including a base 1, a buffer seat 5, a bending pressure plate 10 and a hydraulic rod 12. The four corners of the upper end of the base 1 are fixed with guide pillars 2. The top of the four guide pillars 2 is fixed to the bottom of the same top plate 3. The outside of the four guide pillars is movably connected with guide sleeves 4. The buffer seat 5 is fixed between the four guide sleeves 4. The upper end of the buffer seat 5 is symmetrically fixed with L-shaped slide rails 6. The upper ends of the two L-shaped slide rails 6 are slidably connected with two sliders 7. The top of the two sliders 7 is respectively fixed with a first lower mold 8 and a second lower mold 9. The internal cavities of the first lower mold 8 and the second lower mold 9 form a mold cavity for bending sheet metal parts.

[0030] A bending pressure plate 10 is provided above the mold cavity. The bottom of the bending pressure plate 10 is provided with a concave surface that matches the protrusion inside the mold cavity. The bending plate is driven to press down by the drive plate 11. The drive plate 11 is fixedly installed at the telescopic end of the hydraulic rod 12. The hydraulic rod 12 is fixedly installed at the bottom center of the top plate 3.

[0031] The buffer seat 5 has an internal cavity for a motor 13 and a double-ended lead screw 14. One end of the double-ended lead screw 14 is rotatably connected to the inside of the cavity, and the other end is fixed to the output shaft of the motor 13 via a coupling. Threaded sleeves 15 are installed on the outside of both ends of the double-ended lead screw 14. The bottom of the two threaded sleeves 15 is movably connected to the guide rail 17 inside the cavity via guide blocks 16. The upper ends of the two threaded sleeves 15 are fixed to the bottom of the slider 7 via drive blocks 18. Considering the problem in the prior art where sheet metal parts get stuck in the mold groove of the lower mold, and the sheet metal parts easily cause scratches when ejected by a pusher plate, this device provides a solution for this purpose. The die cavity for metal part processing uses a combination of a first lower die 8 and a second lower die 9. After the sheet metal part is processed by the sheet metal pressure plate and the hydraulic rod 12, the motor 13 drives the double-ended lead screw 14 to rotate. The threaded sleeves 15 at both ends of the double-ended lead screw 14 will move synchronously. That is, the two threaded sleeves 15 drive the first lower die 8 and the second lower die 9 to move outward through the drive block 18, thereby pulling open the die cavity. During this process, the sheet metal part inside the die cavity will complete the demolding process. Compared with the method of using a pusher plate to push the sheet metal part out of the die cavity in the prior art, the friction between the sheet metal part and the die cavity is avoided, which causes damage to the contact surface.

[0032] The drive plate 11 has L-shaped clips 19 fixed on both sides of its bottom for the bending pressure plate 10 to insert into. Each L-shaped clip 19 is reinforced with the bending pressure plate 10 by a fixing bolt 20. Anti-deviation rods 21 are fixed at the four corners of the upper end of the drive plate 11. The top of each anti-deviation rod 21 extends through to the upper end of the top plate 3. The anti-deviation rods 21 guide the moving drive plate 11, ensuring that the drive plate 11 does not shift position during the process of driving the bending pressure plate 10 to descend.

[0033] Each guide sleeve 4 has a first connecting ring 22 fixed at both its upper and lower ends. A second connecting ring 23 is provided on the opposite side of each first connecting ring 22. The second connecting ring 23 is fixed to the outside of the guide pillar 2. A dustproof telescopic sleeve 24 is installed between the first connecting ring 22 and the second connecting ring 23. By setting the dustproof telescopic sleeve 24, the contact surface between the guide sleeve 4 and the guide pillar 2 is protected from dust, thus preventing dust from adhering to the balls inside the guide sleeve 4 and affecting the transmission.

[0034] Among them, a controller 25 is fixed on one side of the front end of the buffer seat 5. The controller 25 is connected to the driver of the motor 13 through wires. The four corners of the bottom of the buffer seat 5 are provided with first moving rails 26. A second moving rail 27 is provided below each first moving rail 26. The second moving rail 27 is fixed to the upper end of the base 1. An X-shaped movable frame 28 is provided between the two first moving rails 26 and the second moving rail 27 on each side. The first moving rails 26 and the second moving rails 27 guide the expansion and contraction of the X-shaped movable frame 28.

[0035] The upper end of the X-shaped movable frame 28 is movably connected to the movable groove in the middle of the first moving rail 26. The lower bottom of the X-shaped movable frame 28 is hinged to the moving block 29 at the upper end of the second moving rail 27. A fixing sleeve 30 for mounting damping rods 31 is fixed to one side of the second moving rail 27 and the upper end of the base 1. A buffer spring 32 is installed on the outside of the telescopic end of each damping rod 31. The two ends of the buffer spring 32 abut against the side wall of the moving block 29 and the housing of the damping rod 31, respectively. By setting the damping rods 31 and buffer springs 32, the X-shaped movable frame 28 is buffered, thus preventing bending. The impact force generated when the pressure plate 10 presses down on the sheet metal parts in the mold cavity causes the buffer seat 5 to descend, resulting in the deformation of the X-shaped movable frame 28. During the deformation process, the two ends of the X-shaped frame will abut against the moving block 29 at the upper end of the moving rail. As the moving block 29 moves horizontally, it will abut against the buffer spring 32 to absorb the impact force and deform. When the buffer spring 32 absorbs the impact force and releases its elastic potential energy, it is suppressed by the damping rod 31, thus completing the buffering process. The above-mentioned buffering structure improves the stability of the device and avoids the problem that the first lower mold 8 and the second lower mold 9 are easily damaged due to the lack of a buffering structure.

[0036] The top plate 3 has L-shaped covers 33 fixed on both sides, and sound-absorbing panels 34 are fixed inside the two L-shaped covers 33. By setting up the L-shaped covers 33 and the sound-absorbing panels 34 inside them, the noise generated during the processing is reduced.

[0037] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
