Description

Technical Field

[0001] This utility model relates to the field of electric bending machine technology, specifically to an electric bending slider assembly. Background Technology

[0002] An electric bending machine is a machine that can bend sheet metal. When working, the motor drives the upper bending block to descend and cooperate with the lower bending block to bend the thin sheet metal. When the upper bending block is raised and lowered, a slider is used to guide the upper bending block to prevent it from deviating.

[0003] In the prior art, when the slider assembly guides the upper bending block, the slider is easily squeezed and tilted when the upper and lower bending blocks press and bend the sheet metal. This causes the slider to rub against the slide block when it rises and falls again, which will cause abnormal noise and cause greater wear on the slider, deforming the slider and affecting the cooperation between the upper and lower bending blocks to bend the sheet metal.

[0004] Therefore, there is an urgent need to design an electric bending slider assembly to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an electric bending slider assembly to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electric bending slider assembly includes an upper bending block, an outer slider, and a bending machine body.

[0008] Both ends of the upper bending block are provided with inner sliders;

[0009] Slides are provided on the inner walls of both sides of the bending machine body;

[0010] The inner slider is slidably connected inside the slide block;

[0011] The bottom of the inner slider is provided with a slot;

[0015] Furthermore, grooves are provided on the outer walls of both sides of the inner slider, and pulleys are provided inside the grooves, with the pulleys rollingly connected to the inner wall of the inner slider.

[0016] Furthermore, connecting blocks are fixedly installed on the outer walls of both sides of the upper bending block, and adjusting screws are inserted into the internal threads of the connecting blocks;

[0017] One end of the adjusting screw is connected to the outer wall of the outer slider, and a guide rod is fixedly installed on the outer wall of one side of the outer slider.

[0018] The connecting block has a guide hole inside, and the guide rod slides through the inside of the guide hole.

[0019] Furthermore, the top shape of both the card slot and the card block is triangular, and the inner wall of the card slot is provided with an arc-shaped surface.

[0020] Furthermore, the two adjacent connecting blocks are located on opposite sides of the slide, and the two adjacent connecting blocks are symmetrical to each other.

[0021] Furthermore, a T-shaped hole is installed on the outer slider, a connecting bolt is installed in the T-shaped hole, an adjusting sleeve is fitted on the outside of the connecting bolt, the connecting bolt is used to connect the guide rod, and set screws are installed at the top and bottom of the outer slider.

[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1-4As shown in the figure, an electric bending slider assembly provided by this utility model includes an upper bending block 1, an outer slider 8, and a bending machine body 17. Inner sliders 2 are provided at both ends of the upper bending block 1. Slide seats 3 are provided on the inner walls of both sides of the bending machine body 17. The inner sliders 2 are slidably connected to the interior of the slide seats 3. A slot 4 is provided at the bottom of the inner sliders 2. A locking block 5 is provided inside the inner wall of the slide seat 3, and the locking block 5 is matched to the specifications of the slot 4, engaging inside the slot 4. Slide grooves 11 are provided on the outer walls of both sides of the slide seat 3, and a semi-cylinder 9 is provided inside the slide grooves 11. A semi-circular groove 10 is provided on the outer wall of the outer slider 8, and the outer slider 8 is sleeved on the outside of the semi-cylinder 9, with the inner wall of the outer slider 8 fitting against the outer wall of the semi-cylinder 9.

[0039] This utility model provides an electric bending slider assembly, including an upper bending block 1, an outer slider 8, and a bending machine body 17.

[0040] Both ends of the upper bending block 1 are provided with inner sliders 2;

[0041] Slides 3 are provided on the inner walls of both sides of the bending machine body 17;

[0042] The inner slider 2 is slidably connected to the inside of the slide block 3;

[0043] The bottom of the inner slider 2 is provided with a slot 4;

[0044] The inner wall of the slide block 3 is provided with a locking block 5, and the locking block 5 is compatible with the specifications of the slot 4. The locking block 5 is engaged inside the slot 4.

[0045] Slide grooves 11 are provided on the outer walls of both sides of the slide block 3, and a semi-cylinder 9 is provided inside the slide grooves 11;

[0046] A semi-circular groove 10 is provided on the outer wall of the outer slider 8. The outer slider 8 is sleeved on the outside of the semi-cylinder 9, and the inner wall of the outer slider 8 is in contact with the outer wall of the semi-cylinder 9. The locking block 5 can be locked in the locking groove 4, thereby preventing the inner slider 2 from being squeezed and deformed by the squeezing force generated when the upper bending block 1 bends the thin plate, thus avoiding the problems of abnormal noise and wear caused by deformation.

[0047] By setting that when the upper bending block 1 descends and is about to cooperate with the lower bending block 16 to bend the thin plate, the locking block 5 will lock into the locking groove 4, which can prevent the inner slider 2 from shifting. This ensures that the inner slider 2 will not be squeezed and deformed by the pressure generated when the upper bending block 1 and the lower bending block 16 bend the thin plate. Furthermore, it also prevents the upper bending block 1 from deforming, thereby avoiding abnormal noise and wear problems caused by the deformation of the inner slider 2.

[0048] In one embodiment provided by this utility model, such as Figure 2 and Figure 3As shown, grooves 6 are provided on the outer walls of both sides of the inner slider 2, and pulleys 7 are provided inside the grooves 6. The pulleys 7 are tumblingly connected to the inner wall of the inner slider 2. When the inner slider 2 rises and falls, the pulleys 7 will roll on the inner wall of the slide block 3, which makes the inner slider 2 rise and fall more smoothly.

[0049] In another embodiment provided by this utility model, such as Figure 2 and Figure 3 As shown, connecting blocks 12 are fixedly installed on the outer walls of both sides of the upper bending block 1, and adjusting screws 13 are inserted into the internal threads of the connecting blocks 12. Rotating the adjusting screws 13 can drive the outer slider 8 to move.

[0050] One end of the adjusting screw 13 is connected to the outer wall of the outer slider 8. A guide rod 14 is fixedly installed on the outer wall of one side of the outer slider 8. The guide rod 14 is used to guide the outer slider 8.

[0051] The connecting block 12 has a guide hole 15 inside, and the guide rod 14 slides through the inside of the guide hole 15. When the outer slider 8 moves, the guide rod 14 will slide inside the guide hole 15, and the guide rod 14 can guide the outer slider 8.

[0052] In another embodiment provided by this utility model, such as Figure 2 and Figure 3 As shown, the tops of both the slot 4 and the block 5 are triangular, and the inner wall of the slot 4 is provided with an arc-shaped surface 18 to facilitate the block 5 to be inserted into the slot 4.

[0053] In one embodiment provided by this utility model, such as Figure 1 As shown, the two adjacent connecting blocks 12 are located on both sides of the slide block 3. The two adjacent connecting blocks 12 are symmetrical to each other and are guided from both sides of the upper bending block 1, which has a better effect.

[0054] In one embodiment provided by this utility model, such as Figure 5 As shown, the outer slider 8 is equipped with a T-shaped hole, a connecting bolt 81 is installed in the T-shaped hole, an adjusting sleeve 82 is fitted on the outside of the connecting bolt 81, the connecting bolt 81 is used to connect the guide rod 14, and a limit ring is provided on the outer side of the end of the connecting guide rod 14. The top and bottom of the outer slider 8 are both equipped with set screws 83.

[0055] The root of the adjusting sleeve 8 is provided with an adjusting slope, which corresponds to the position of the top screw 83.

[0056] The adjustment screw 13 and the outer slider 8 are connected by a ball joint to reduce the shear force during the adjustment process and ensure the fit between the outer slider 8 and the semi-cylinder 9.

[0057] Due to machining and assembly errors in various components during installation, the outer slider 8 and the semi-cylinder 9 may not fit effectively together. Therefore, it is necessary to adjust the fit between the outer slider 8 and the semi-cylinder 9 during the debugging phase. Poor fit can also lead to problems such as abnormal noise and stiff movement. The inventors adjusted the set screw on the adjustment slope to bring the outer slider 8 closer to the guide rod 14, thereby adjusting a certain angle to achieve effective fit between the mating surfaces. Since the adjustment angle is very small, the adjustment range in the horizontal position is about 1-5 microns. The fit clearance between the T-hole, the guide rod 14, and the connecting bolt 81 fully meets the adjustment range and there will be no interference problem.

[0058] In another embodiment provided by this utility model, such as Figure 1 As shown, a lower bending block 16 is provided on the inner wall of the bending machine body 17, and the two ends of the lower bending block 16 are located inside the slide block 3. The upper bending block 1 and the lower bending block 16 cooperate to extrude and bend the thin plate.

[0059] Working principle:

[0060] When the drive component on the bending machine body 17 drives the upper bending block 1 to descend, the inner slider 2 slides in the slide block 3, the outer slider 8 slides in the slide groove 11, and the outer slider 8 slides outside the semi-cylinder 9, which can provide a stable guiding effect for the upper bending block 1. When the upper bending block 1 descends to the point where it is about to apply force to bend the thin plate, the locking block 5 will lock in the locking groove 4, which can prevent the inner slider 2 from being squeezed and deformed by the pressure generated when the upper bending block 1 and the lower bending block 16 bend the thin plate, thus achieving the anti-deformation function. This can avoid the problem of abnormal noise or wear of the inner slider 2 caused by deformation. When a small gap is found between the outer slider 8 and the semi-cylinder 9, the adjusting screw 13 is rotated to push and drive the outer slider 8 to move, so that the outer slider 8 is tightly attached to the outer wall of the semi-cylinder 9, which can ensure that the outer slider 8 can provide a stable guide for the upper bending block 1.

[0061] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
