Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing equipment, in particular to a sheet metal bending device. Background Art

[0002] Sheet metal parts are manufactured from sheet metal. Sheet metal fabrication involves forming sheet metal into desired shapes and sizes through processes such as stamping, bending, cutting, and shearing. Sheet metal parts are widely used in various industries, including automotive, aerospace, electronics, and construction. During the sheet metal fabrication phase, molds and sheet metal are processed through processes such as stamping, bending, and cutting to form the desired shape. Finally, the sheet metal parts are assembled and inspected according to product specifications.

[0003] A sheet metal bending machine is a machine that can bend thin sheets of metal, such as a precision sheet metal bending device disclosed in Chinese patent CN118080626A. This type of equipment has a large structure and volume and is generally placed in a processing workshop for use. When in use, the control host transmits commands to the drive device, which drives the upper bending die to move up and down and cooperate with the lower bending die. The bending machine can meet the needs of various thin plate parts by replacing the bending machine mold. After actual market research, the applicant found that in some specific scenarios, such as small structural development laboratories with limited space, temporary processing sites in remote locations, etc., there is also a large demand for bending processing of sheet metal parts, but the bending structure is often single and the processing volume is small. In addition, due to limited space or cost, it is impossible to configure large-scale bending machine equipment. At present, the drawings can only be sent to external sheet metal processing workshops, waiting for the order to be processed, and then the workpiece is transported back after processing, which makes the bending process time-consuming and labor-intensive. The processing party often refuses because of the small quantity and cumbersomeness, and there is a hidden danger of technology leakage. Utility Model Content

[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] Combine Figure 1-4 This embodiment discloses a sheet metal bending device, which aims to solve the problem of difficult sheet metal bending processing in some small or temporary work sites.

[0030] The device specifically includes a frame 1, a punching platform 11, a mounting seat 2, a punching plate 3, a slider 6, a rocker arm 4 and a supporting bracket 7.

[0031] The frame 1 is made of metal profiles, and in this embodiment, it is made of aluminum alloy square tubes. An inverted "T"-shaped support leg structure is provided at the bottom thereof, which can provide a sufficiently stable support effect.

[0032] A horizontally mounted punching platform 11 is located on top of the frame 1. The punching platform 11 is a horizontally mounted plate structure with vertical ribs at its bottom, forming a T-shaped longitudinal profile. This provides sufficient structural strength to provide bottom support during the bending and stamping of sheet metal parts. In this embodiment, the top of the punching platform 11 is a horizontal end surface. In other embodiments, a bending die is removably mounted on the top of the punching platform 11 using countersunk bolts, and a groove structure can be used to achieve a specific bending and shaping effect.

[0033] A mounting seat 2 extending vertically upward is provided on the left and right sides of the stamping table 11. The bottom of the inner side wall of the mounting seat 2 is welded and fixed to the left and right sides of the stamping table 11. A vertical track 21 is provided on the mounting seat 2. The track 21 passes through the mounting seat 2 horizontally on the left and right sides. A slider 6 is movably connected in the track 21. A concave-convex clip structure is formed between the slider 6 and the track 21, and the slider 6 can slide up and down stably along the track 21.

[0034] Furthermore, the inner end of the slider 6 is connected to the stamping plate 3, and the bottom of the stamping plate 3 is a narrow-edge structure, which is adapted to the bending and stamping requirements. Its specific structure is an existing technology, and its specific structure and working principle will not be repeated here. Those skilled in the art can select and implement it from the existing technology according to actual operating conditions.

[0035] The outer end of the slider 6 is hinged to the rocker arm 4 through a rotating structure. Swinging the rocker arm 4 in the threshold direction can drive the stamping plate 3 to move closer to the stamping table 11. After the rocker arm 4 swings to the threshold angle, it can form a folding storage structure with the frame 1. The outer end of the slider 6 is hinged to the rocker arm 4 through a connecting rod 5, and the hinged end of the rocker arm 4 and the connecting rod 5 are coaxially hinged on the outer wall of the mounting base 2. In order to make the grip more comfortable and not to wear the hands, the outer end of the rocker arm 4 is provided with a handle made of rubber material, and the left and right rocker arms 4 are connected by a rib plate 41 to form a linkage structure. This allows one hand to pull the rocker arm 4 on one side during operation, and the rocker arm 4 on the other side will also swing synchronously.

[0036] Furthermore, the mounting seat 2 is hingedly connected to a support bracket 7 on one side of the stamping table 11. The support bracket 7 is used to provide auxiliary support to the sheet metal structure when bending relatively large sheet metal parts, making the bending operation more accurate and reliable, and the bending deformation more stable.

[0037] After the support bracket 7 is flipped upward, it can be clamped on one side of the punching table 11 in a horizontal posture. After the support bracket 7 is flipped downward, it can form a folding storage structure with the frame 1. Specifically, the top of the support bracket 7 is a flat frame, and a support rod 71 is hinged at the center position of the bottom. The support rod 71 is hinged to the frame 1 through a sleeve. A spring 72 is sleeved on the support rod 71 above the sleeve. The spring 72 can form an elastic support structure of the top frame after the support bracket 7 is flipped upward. Since the top is hinged, the bottom and the frame 1 only need to be provided with a sleeve, and the sleeve and the frame 1 also adopt a hinged structure, so that during the flipping process of the support bracket 7, the support rod 71 can move axially relative to the sleeve. Through the threshold design, when the support bracket 7 is flipped upward, the connection angle of the top of the support rod 71 changes, and the spring 72 has sufficient elastic support force to support the support bracket 7 so that it maintains a horizontal posture.

[0038] During the specific implementation process, the support frame 7 is first flipped up, and the rocker arm 4 is used to control the stamping plate 3 to move upward. A stamping gap for accommodating sheet metal parts is formed between the bottom of the stamping plate 3 and the stamping table 11. The sheet metal parts are inserted into the stamping gap according to the threshold conditions, and then the rocker arm 4 is used to control the stamping plate 3 to move downward, and the stamping table 11 is used to clamp and fix the sheet metal parts. After confirming the position accuracy, a certain force is applied to cause the sheet metal parts to undergo corresponding bending deformation, thereby realizing the bending processing of the sheet metal parts.

[0039] In another embodiment, combined Figure 5As shown, in order to make the tooling of the sheet metal more precise, a linear laser module 8 is provided at the inner end of the mounting seat. The linear laser module 8 can project a straight beam of light to the stamping station to form an alignment reference structure for the sheet metal.

[0040] Furthermore, an angle adjustment structure is provided between the linear laser module 8 and the inner sidewall of the mounting base 2. Specifically, the linear laser module 8 is fixedly mounted on a plate, which is connected to the mounting base 2 via a hinged shaft, allowing for fine adjustment of the linear laser module's mounting angle. In other embodiments, a combination of strip-shaped holes and bolts may be provided between the linear laser module and the plate to achieve adjustable mounting position.

[0041] In order to make the device more maneuverable and more convenient to transport, a traveling wheel with a braking structure may be further provided at the bottom of the frame 1 .

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
