Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, specifically a bending device for sheet metal processing. Background Technology

[0002] Sheet metal processing is a process of processing thin sheet metal. Through stamping, bending, welding, cutting and other means, sheet metal is processed into parts of the required shape and size. Sheet metal processing plays an important role in modern manufacturing and is widely used in various fields. Through various processing methods, sheet metal is processed into parts of various shapes and sizes to meet the needs of different products.

[0003] In the process of bending sheet metal parts, a bending device is required to bend the sheet metal parts. Currently, the bending devices on the market have relatively fixed positions of the bending blade and the pressure die, which cannot be quickly adjusted. This increases the difficulty of operation during the bending process. Furthermore, when different types of pressure dies need to be used during processing, the position of the pressure die cannot be fine-tuned. This makes it easy for the bending blade to become incompatible with the sheet metal during bending, affecting the bending effect of the sheet metal. Therefore, a bending device for sheet metal processing is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a bending device for sheet metal processing. This device offers the advantages of relatively adjustable positions of the bending blade or die holder, with a simple and quick adjustment method. It solves the problem that in the process of bending sheet metal parts, the bending blade and die holder in existing devices are fixed in position, making quick adjustment impossible. This increases the difficulty of operation during bending and prevents fine-tuning of the die holder's position when different types of die holders are used. Consequently, incompatibility with the bending blade can easily occur during sheet metal bending, affecting the bending effect.

[0008] The beneficial effects of this utility model are:

[0009] This sheet metal bending device has the advantages of being able to adjust the position of the bending knife or the die holder, and the adjustment method is simple and quick.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the rotating device includes a worm gear rotatably connected to the inside of the fixed frame, and two threaded rods, each connected to the connecting plate via threaded transmission, are rotatably connected to the inside of the fixed frame. The outer sides of the two threaded rods are fixedly connected to worm wheels that mesh with the worm gear.

[0012] The advantage of adopting the above-mentioned further solution is that it enables the connecting plate to move back and forth a certain distance to change the position of the bending blade, making it convenient to adjust and fix the position of the bending blade.

[0013] Furthermore, the fixed frame is internally fixedly connected with two limiting rods, both of which are slidably connected to the connecting plate, and the worm gear is fixedly connected to a knob located outside the fixed frame.

[0015] Furthermore, a first sliding groove is provided inside the fixed frame, and a first sliding plate that is slidably connected to the first sliding groove is fixedly connected to both the front and rear sides of the mounting plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it further restricts the movement direction of the bending knife and provides stable support for fixing the mounting plate and connecting plate.

[0017] Furthermore, the base has a second sliding groove inside which it is slidably connected to the second sliding plate. The cross-section of the second sliding groove is convex, and a friction pad is provided on the inner top wall of the second sliding groove.

[0018] The beneficial effect of adopting the above-mentioned further solution is to prevent the second slide from falling off the second slide groove and to limit the sliding direction of the second slide.

Detailed Implementation

[0027] 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.

[0028] In the embodiments, by Figure 1-5A bending device for sheet metal processing is provided. The present invention includes a base 1, a support frame 2 fixedly connected to the top of the base 1, two hydraulic push rods 3 symmetrically distributed on the left and right sides fixedly connected inside the support frame 2, the bottom of the two hydraulic push rods 3 being fixedly connected to a fixed frame 4, a rotating device 5 being provided inside the fixed frame 4, a connecting plate 6 being connected to the outside of the rotating device 5 via a threaded drive, a mounting plate 7 being fixedly connected to the bottom of the connecting plate 6, a bending knife 8 being fixedly connected to the inside of the mounting plate 7 via fasteners, a second sliding plate 9 being slidably connected inside the base 1, a fixed rod 15 extending through and to the outside of the base 1 being fixedly connected to the top of the second sliding plate 9 via fasteners, and a pressure mold seat 10 being fixedly connected to the top of the second sliding plate 9 via fasteners.

[0029] The rotating device 5 includes a worm 51 that is rotatably connected to the inside of the fixed frame 4. The inside of the fixed frame 4 is rotatably connected to two threaded rods 52, both of which are connected to the connecting plate 6 by threaded transmission. The outer sides of the two threaded rods 52 are fixedly connected to worm wheels 53 that mesh with the worm 51.

[0030] In this embodiment, during actual use, the rotation of the worm 51 causes the worm wheel 53 on the outside of the threaded rod 52 to rotate, thereby causing the threaded rod 52 to rotate, and the connecting plate 6 to move under the action of the thread of the threaded rod 52.

[0031] The fixed frame 4 has two limiting rods 11 that are slidably connected to the connecting plate 6 inside, and the worm gear 51 has a knob 12 located outside the fixed frame 4.

[0032] In this embodiment, during actual use, the limiting rod 11 restricts the movement direction of the connecting plate 6. The limiting rod 11 and the threaded rod 52 are set in parallel, and the knob 12 can rotate the worm gear 51.

[0033] The fixed frame 4 has a first sliding groove inside, and the front and rear sides of the mounting plate 7 are fixedly connected with first sliding plates 13 that are slidably connected to the first sliding groove.

[0034] In this embodiment, during actual use, when the connecting plate 6 moves the mounting plate 7, the first sliding plate 13 in front of and behind the mounting plate 7 will slide in the first sliding groove. The first sliding groove restricts the movement direction of the mounting plate 7 and provides support for the mounting plate 7, preventing the mounting plate 7 from shifting and falling off.

[0035] The base 1 has a second sliding groove inside which it is slidably connected to the second sliding plate 9. The cross-section of the second sliding groove is convex, and a friction pad is provided on the top wall inside the second sliding groove.

[0036] In this embodiment, during actual use, the second slide groove restricts the movement direction of the second slide plate 9, and the convex second slide groove makes it difficult for the second slide plate 9 to be lifted from above. The friction pad increases the friction between the second slide plate 9 and the interior of the base 1, making the fixation of the second slide plate 9 more stable and secure.

[0037] The second slide plate 9 has an internal threaded connection with a bolt 14 that passes through and extends to the outside of the second slide plate 9, and the fixing rod 15 has an external threaded connection with a threaded sleeve 16.

[0038] In this embodiment, during actual use, when the bolt 14 is tightened, the second slide plate 9 will move upward under the action of the thread, with the bolt 14 pressing against the bottom wall of the second slide groove. At this time, the second slide plate 9 will not easily move downward and fall off under the action of the friction pad through pressure and friction. Subsequently, the threaded sleeve 16 and the fixing rod 15 can be twisted together to strengthen the fixation of the second slide plate 9, so that the position of the mold base 10 remains stable. When the bolt 14 and the threaded sleeve 16 are loosened, the second slide plate 9 can move left and right in the second slide groove to adjust the position of the mold base 10 on its outer side.

[0039] Working principle:

[0040] When bending sheet metal, under normal circumstances, the bending blade 8 can be pressed down by the hydraulic push rod 3 to complete the pressing under the constraint of the die holder 10. When it is necessary to replace and adjust the bending blade 8 and the die holder 10, the connecting plate 6 can be rotated by turning the knob 12, thereby moving the bending blade 8 longitudinally to adjust its position. The die holder 10 does not usually need to be adjusted. However, after the die holder 10 is replaced, some of the holes of the die holder 10 are not symmetrically distributed. If its fixing hole position is offset, the die holder 10 needs to be moved directly below the bending blade 8. At this time, the fixing of the second slide plate 9 can also be loosened by removing the bolt 14 and the threaded sleeve 16, so that the die holder 10 and the second slide plate 9 below it can move laterally relative to the base 1 to adjust the left and right lateral position of the die holder 10. After the adjustment is completed, the second slide plate 9 can be re-fixed by tightening the bolt 14 and the threaded sleeve 16.
