[0001] This utility model belongs to the field of bending machine technology, and in particular relates to a bending machine for the production of metal products. Background Technology

[0002] CNC bending machines use equipped dies to bend cold metal sheets into workpieces of various geometric cross-sectional shapes. They are sheet metal forming machines designed for cold-rolled sheet metal processing and are widely used in sheet metal bending processes in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles.

[0003] In the prior art, such as Chinese Utility Model Publication No. CN221312008U, a bending mechanism for a bending machine is disclosed, including a bending machine. A groove is formed on the outer side of the bending machine, and a threaded rod is rotatably installed on the inner side of the groove. A bracket is slidably installed on the circumferential surface of the threaded rod, and a slide table is slidably installed on the bracket. A rotating plate is rotatably installed on the upper end of the slide table, and a rotating groove is formed on the rotating plate. A connector is slidably installed on the inner side of the rotating groove, and the other end of the connector has a U-shaped structure.

[0004] However, the steel plate in the above patent is suspended in the air, which has insufficient support. During the bending process, the suspended part is prone to bending due to gravity and mechanical force, resulting in undesirable creases on the workpiece. Therefore, we propose a bending machine for metal product manufacturing. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a bending machine for the production of metal products, which prevents the formation of undesirable creases by providing good support for steel plates, and allows even small steel plate workpieces to be well supported by an adjustable support frame.

[0006] This utility model is implemented as follows: a bending machine for producing metal products includes a bending machine body. A mounting groove is provided on the front side of the bending machine body. A reduction motor is connected inside the mounting groove. A bidirectional lead screw is fixedly connected to the output shaft of the reduction motor. Two support frames are provided on the front side of the bending machine body. The bidirectional lead screw is used to drive the two support frames to move towards or relative to each other. A support plate is provided on the upper part of each support frame. A pressing component is installed on the support frame. Several strip-shaped holes are provided on the support plate. The upper part of the pressing component passes through the strip-shaped holes.

[0007] Optionally, the pressing assembly includes a support rod, a top plate welded to the upper part of the support rod, an electric cylinder fixedly connected to the top plate, and a pressure plate fixedly connected to the lower end of the telescopic rod of the electric cylinder through the top plate.

[0008] Optionally, the lower part of the support rod is connected to the support frame by threads, the support frame has a strip groove, the bottom of the support frame has several screw holes, and the lower part of the support rod is connected to a hexagonal nut.

[0009] Optionally, a slider is welded to the rear of the support frame, and the bidirectional lead screw is connected to the slider via a lead screw nut.

[0010] Optionally, a support frame is fixedly connected to the front side of the bending machine body. The support frame is connected to the support plate by bolts. The support frame is provided with a groove. A positioning block is fixedly connected to the lower part of the support plate.

[0011] Optionally, a hydraulic cylinder is installed on the bending machine body, the piston rod of the hydraulic cylinder is drivenly connected to a bending knife, and a bending groove is installed on the bending machine body.

[0012] Optionally, a widening plate can be used to replace the support plate, the width of which is greater than that of the support plate, and the widening plate is provided with strip-shaped openings.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting an mounting groove on the front side of the bending machine body and connecting a reduction motor inside it, a double-acting lead screw is fixedly connected to the output shaft of the reduction motor. Simultaneously, a slider is welded to the rear of the support frame. The double-acting lead screw is connected to the slider via a lead screw nut, enabling the two support frames to move towards or relative to each other as needed. The purpose of this design is to accommodate steel plate workpieces of different sizes, ensuring uniform support during bending. This not only avoids undesirable creases caused by improper support but also improves the applicability and flexibility of the bending machine, allowing even smaller steel plate workpieces to receive good support, thereby improving bending quality and efficiency.

[0015] The narrower support plate or the wider plate can be selected according to the actual width of the steel plate workpiece. The bottom of the support frame has multiple sets of screw holes. The appropriate screw hole position can be selected to install the pressing component according to actual needs. When using the widening plate, two sets of holes that are far apart should be selected so that the pressing component can cover a wider steel plate.

[0016] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0025] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] like Figures 1 to 7 As shown in the figure, this utility model provides a bending machine for producing metal products.

[0027] The machine includes a bending machine body 2. A mounting groove 7 is provided on the front side of the bending machine body 2. A reduction motor 11 is connected inside the mounting groove 7. A double-acting lead screw 10 is fixedly connected to the output shaft of the reduction motor 11. Two support frames 3 are provided on the front side of the bending machine body 2. The double-acting lead screw 10 is used to drive the two support frames 3 to move towards or relative to each other. A support plate 4 is provided on the upper part of the support frame 3. A pressing component 5 is installed on the support frame 3. Several strip holes 41 are provided on the support plate 4. The upper part of the pressing component 5 passes through the strip holes 41.

[0028] The pressing assembly 5 includes a support rod 53, a top plate 52 welded to the upper part of the support rod 53, an electric cylinder 51 fixedly connected to the top plate 52, and a pressure plate 54 fixedly connected to the lower end of the telescopic rod of the electric cylinder 51 through the top plate 52.

[0029] The lower part of the support rod 53 is connected to the support frame 3 by threads. The support frame 3 has a strip groove 31 and several screw holes 33 at the bottom. The lower part of the support rod 53 is connected to a hexagonal nut 55.

[0030] A slider 32 is welded to the rear of the support frame 3, and the bidirectional lead screw 10 is connected to the slider 32 through the lead screw nut.

[0031] A support frame 6 is fixedly connected to the front side of the bending machine body 2. The support frame 6 is connected to the support plate 4 by bolts. The support frame 6 is provided with a groove 61. A positioning block 42 is fixedly connected to the lower part of the support plate 4.

[0032] A hydraulic cylinder 1 is installed on the bending machine body 2. The piston rod of the hydraulic cylinder 1 is connected to a bending knife 8. A bending groove 9 is installed on the bending machine body 2.

[0033] In some embodiments, the support plate 4 is replaced by a widening plate 12, the width of which is greater than that of the support plate 4, and the widening plate 12 is provided with a strip-shaped opening 121.

[0034] The narrower support plate 4 or the widening plate 12 can be selected according to actual needs. The bottom of the support frame 3 has multiple sets of screw holes 33. The appropriate screw hole 33 position can be selected to install the pressing component 5 according to actual needs. When using the widening plate 12, two sets of holes with a greater distance should be selected so that the bending machine can be used for steel plate workpieces of different widths.

[0035] Working principle: In operation, the steel plate workpiece to be bent is first placed in an appropriate position on the bending machine body 2. Then, according to the specific dimensions of the steel plate workpiece, the reduction motor 11 is started. The reduction motor 11 drives the bidirectional lead screw 10 on its output shaft to rotate. Since the bidirectional lead screw 10 is connected to the slider 32 at the rear of the support frame 3 via a lead screw nut, as the bidirectional lead screw 10 rotates, the two support frames 3 will move towards or relative to each other until they are adjusted to a position suitable for the width of the steel plate workpiece.

[0036] The pressing assembly 5 includes an electric cylinder 51, a top plate 52, a support rod 53, and a pressure plate 54. The lower part of the support rod 53 is connected to the support frame 3 by threads. After adjusting the position of the support frame 3, the support rod 53 is fixed to the support frame 3 through the screw hole 33 and the hexagonal nut 55. At this time, the top plate 52 and the pressure plate 54 of the pressing assembly 5 will pass through the strip hole 41 on the support plate 4 and be positioned above the steel plate workpiece.

[0037] Next, start the electric cylinder 51. The telescopic rod of the electric cylinder 51 extends downward, causing the pressure plate 54 to press tightly against the upper surface of the steel plate workpiece, thereby limiting and fixing the steel plate.

[0038] Finally, the hydraulic cylinder 1 on the bending machine body 2 is activated. The piston rod of the hydraulic cylinder 1 drives the bending blade 8, causing the bending blade 8 to bend the steel plate workpiece along the bending groove 9. Since the support frame 3 and support plate 4 provide good support for the steel plate workpiece, and the pressing component 5 ensures the stability of the steel plate workpiece during the bending process, a high-quality bending effect can be obtained.

[0039] Throughout the entire operation, the support bracket 6 is connected to the support plate 4 by bolts, which further stabilizes the support plate 4. The positioning block 42 at the bottom of the support plate 4 cooperates with the groove 61 on the support bracket 6 to ensure the accurate installation and positioning of the support plate 4.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
