Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, and more specifically, it relates to a sheet bending machine. Background Technology

[0002] In the field of metal sheet processing and manufacturing, bending is the core process for forming sheet metal. It is widely used in many industrial fields such as automobile manufacturing, home appliance production, building decoration, and aerospace. Sheets of different specifications, thicknesses and materials have different requirements for bending angle, bending radius and processing pressure. Different processes of the same batch of products may also require multiple adjustments to bending parameters. Therefore, bending equipment needs to have flexible height adjustment capabilities to adapt to diverse processing needs.

[0003] Traditional sheet metal bending machines primarily rely on manual screw lifting or hydraulic cylinder drive to adjust the height of the pressure rollers or adjusting rollers. While these methods can achieve continuous height changes, they lack reliable and quick locking mechanisms once the target position is reached. Manual screw adjustment requires operators to continuously rotate the handwheel until the predetermined height is achieved, making the process time-consuming and labor-intensive. This is particularly problematic in production environments requiring significant adjustments or frequent changes in processing parameters, where the low adjustment efficiency severely impacts production cycle time. Hydraulic drive offers faster adjustment speeds but is complex, costly, and difficult to maintain. Leaks and pressure fluctuations in the hydraulic system can also affect positioning accuracy and repeatability, leading to unstable bending quality. Once the position is fixed, these traditional adjustment methods rely mainly on friction or hydraulic locking valves to maintain the position. Under the impact loads and vibrations generated during bending, position drift can easily occur, making it impossible to guarantee long-term stability of processing accuracy. Utility Model Content

A limiting hole is opened on the outer side of the limiting sleeve, multiple sets of limiting holes are provided, and an unlocking hole is opened at one end. Multiple sets of sliding rods slide in multiple sets of limiting holes respectively, which optimizes the rotation and limiting functions of the device and ensures the smoothness and stability of the adjustment and unlocking process.

[0009] The present invention is further configured such that both the positioning rod and the positioning groove are polygonal, which enhances the accuracy and robustness of the positioning system and prevents operational errors caused by inaccurate positioning.

[0010] The present invention is further configured such that the bottom ends of the multiple sets of locking blocks and the inner side of the push plate are all arc-shaped, which improves the connection method of the locking components, makes the contact between the push plate and the locking blocks more stable, and reduces friction and wear during locking.

[0022] In this embodiment, during use, the slider 3 is slid along the support frame 1 to a suitable height and the adjustment hole 8 is aligned with the insertion hole 9. The insertion rod 10 is inserted into the insertion hole 9 and the adjustment hole 8 and then inserted into the fixing sleeve 12.

The fixing sleeve 12 abuts against the outer wall of the sleeve 7 to fix the insertion rod 10. At this time, multiple sets of sliding rods 27 are in the limiting hole 29, and multiple sets of limiting blocks 28 abut against both sides of the limiting sleeve 23, thereby limiting the limiting sleeve 23 and completing the fixing of the adjusting roller 5. The motor 33 is started to drive the rotating rod 4 to rotate, and the rotating rod 4 drives the adjusting roller 5 to rotate. The adjusting roller 5 and multiple sets of bending rollers 2 bend the sheet material.

Pushing the unlocking sleeve 20 causes the multiple sets of push plates 19 to push the locking block 15 away from the locking groove 18, releasing the locking with the locking rod 11. Then the insertion rod 10 can be pulled out of the adjustment hole 8 and the insertion hole 9, completing the unlocking of the insertion rod 10.

[0029] In summary, when using or operating the overall equipment: During use, slide the slider 3 along the support frame 1 to a suitable height and align the adjustment hole 8 with the insertion hole 9. Insert the insertion rod 10 into the insertion hole 9 and the adjustment hole 8, and insert it into the fixing sleeve 12. Insert the positioning rod 13 into the positioning groove 17, causing multiple sets of push springs 16 to push the locking block 15 into the locking groove 18 to lock the insertion rod 10. The fixing sleeve 12 abuts against the outer wall of the sleeve 7 to fix the insertion rod 10. At this time, multiple sets of sliding rods 27 are in the limiting hole 29, and multiple sets of limiting blocks 28 abut against both sides of the limiting sleeve 23, thereby limiting the limiting sleeve 23 and fixing the adjusting roller 5. Start the motor 33 to drive the rotating rod 4 to rotate, and the rotating rod 4 drives the adjusting roller 5 to rotate. The adjusting roller 5 and multiple sets of bending rollers 2 bend the sheet metal.

[0030] When it is necessary to unlock the insertion rod 10, rotate the rotating sleeve 24 to make multiple sets of sliding rods 27 slide into the unlocking hole 30, release the multiple sets of limiting blocks 28 from the sides of the limiting sleeve 23, release the restriction on the limiting sleeve 23, and pull the limiting sleeve 23 out of the limiting groove 22 by the contraction spring 25, release the restriction on the multiple sets of push plates 19, push the unlocking sleeve 20 to make the multiple sets of push plates 19 push the locking block 15 out of the locking groove 18, release the locking with the locking rod 11, and then the insertion rod 10 can be pulled out of the adjustment hole 8 and the insertion hole 9 to complete the unlocking of the insertion rod 10.
