Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a bending mechanism for forming sheet metal parts. Background Technology

[0002] Sheet metal forming is a widely used process in manufacturing, involving multiple processing steps such as cutting, bending, stamping, welding, and assembly of metal sheets. With the acceleration of industrialization, especially in industries such as automotive, electronics, aerospace, and home appliances, the demand for sheet metal parts is increasing daily. The background of sheet metal processing mainly stems from its flexibility and efficiency in product design. Sheet metal materials typically possess good plasticity and strength, enabling them to meet diverse design requirements. Through advanced CNC technology and automated equipment such as laser cutting, sheet metal processing not only improves production efficiency but also reduces labor costs, achieving high-precision and high-consistency production. Furthermore, the concepts of environmental protection and sustainable development have also driven the progress of the sheet metal processing industry; many companies have adopted more environmentally friendly materials and processes in their production processes, reducing waste and energy consumption.

[0003] In existing molds, although there is a pre-bending step when bending sheet metal parts, there is no corresponding angle shaping structure to adapt to the sheet metal parts specifications required by customers during the subsequent bending process. As a result, the bending work of sheet metal parts is limited and the scope of application is small. Therefore, there is an urgent need for a bending mechanism for processing and forming sheet metal parts. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bending mechanism for sheet metal processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bending mechanism for forming sheet metal parts includes a mold body assembled from an upper clamping plate, a stop plate, a stripper plate, and a lower template stacked from top to bottom. A pressure rod one and a pressure rod two are inserted into the upper clamping plate and the stop plate. A mold base one and a mold base two are fixedly connected inside the lower template. A workpiece is placed on the top of the lower template, and a guide ball is rotatably connected to one corner of the bottom of the pressure rod two.

[0007] As a further embodiment of this utility model: a mold base three is fixedly connected inside the lower mold template, and a movable seat is slidably connected to the side of the lower mold template close to the mold base three, and a spring is fixedly connected between the mold base three and the movable seat.

[0008] As a further improvement of this utility model: an angle adjustment component is provided between the mold base three and the movable base, and a pressure rod three is vertically slidably connected inside the upper clamping plate and the stop plate.

[0009] As a further improvement of this utility model: a fine-tuning rod is horizontally slidably connected to one side of the top of the upper clamping plate, and the contact surface between the pressure rod three and the fine-tuning rod is an inclined structure.

[0010] As a further embodiment of this utility model: the angle adjustment component includes an arc surface one, a triangular groove, a mounting hole one, an inclined surface, an arc surface two, a groove and a mounting hole two, and the arc surface one is located at one corner of the mold base three, and the triangular groove is located on one side of the mold base three.

[0011] As a further embodiment of this utility model: the first mounting hole and the second mounting hole are respectively opened on the opposite side of the mold base and the movable base, and the two ends of the spring are fixedly connected to the inner side of the first mounting hole and the second mounting hole, and the second arc surface is opened at one corner of the top of the movable base.

[0012] As a further improvement of this utility model: the inclined surface is located at a corner of the movable seat away from the arc surface two, the inclined surface is adapted to the bottom end of the pressure rod three, and the groove is opened on one side of the movable seat.

[0013] Compared with the prior art, this utility model provides a bending mechanism for sheet metal processing and forming, which has the following beneficial effects:

[0014] 1. This sheet metal bending mechanism, during operation, causes the fine-adjustment rod to move horizontally, pushing the pressure rod three downwards and vertically. At this time, the bottom end of the pressure rod three contacts the inclined surface of the bottom of the moving seat, and drives the moving seat to move towards the position of the mold base three. The workpiece with a 90° angle located at the top of the mold base three is squeezed by one corner of the top of the moving seat. The squeezed side of the workpiece fits into the triangular groove, and the spring located between the mounting hole one and the mounting hole two is also squeezed. This facilitates the shaping of the bending angle of the workpiece, thereby meeting the customer's requirements for the angle specifications of the sheet metal parts and expanding the applicability of the device.

[0015] 2. This sheet metal part forming bending mechanism, when performing a 45° pre-bending operation, moves the first pressure rod vertically downwards, causing one end of the workpiece to fit against the 45° inclined surface of the first mold base, thus completing the 45° pre-bending operation at the workpiece end; when performing a 90° bending operation, moves the second pressure rod vertically downwards, causing the workpiece that has completed the 45° pre-bending to fit against the vertical angle of the second mold base, and the guide ball located at the bottom of the second pressure rod presses the end of the workpiece, thus completing the 90° bending operation at the end of the workpiece. By performing the 45° pre-bending operation and the 90° bending operation, the forming force required for the sheet metal part can be effectively reduced, the load on the processing equipment can be reduced, and the service life of the equipment can be extended. It also makes it easier for the sheet metal part to reach the required angle in the subsequent bending process, improving the accuracy and consistency of forming.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] A bending mechanism for forming sheet metal parts, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mold body is assembled from an upper clamping plate 1, a stop plate 2, a stripper plate 3, and a lower template 4 stacked from top to bottom. A pressure rod 6 and a pressure rod 9 are inserted into the upper clamping plate 1 and the stop plate 2. A mold base 5 and a mold base 7 are fixedly connected inside the lower template 4. A workpiece 8 is provided on the top of the lower template 4, and a guide ball is rotatably connected to one corner of the bottom of the pressure rod 9.

[0026] When performing the 45° pre-folding operation, the pressure rod 6 moves vertically downwards, causing one end of the workpiece 8 to fit against the 45° inclined surface of the mold base 5, thus enabling the end of the workpiece 8 to complete the 45° pre-folding operation.

[0027] When performing a 90° bend, the pressure rod 29 moves vertically downwards, causing the workpiece 8, which has been pre-bent at 45°, to come into contact with the vertical angle of the mold base 27. The guide ball located at the bottom of the pressure rod 29 presses the end of the workpiece 8, causing the end of the workpiece 8 to complete the 90° bend.

[0028] To enable free adjustment of the bending angle of workpiece 8 and expand the applicability of the device, such as... Figure 3 As shown, a mold base 3 12 is fixedly connected inside the lower template 4, and a movable seat 14 is slidably connected to the side of the lower template 4 near the mold base 3 12. A spring 13 is fixedly connected between the mold base 3 12 and the movable seat 14.

[0029] An angle adjustment assembly is provided between the mold base 12 and the movable base 14, and a pressure rod 10 is vertically slidably connected inside the upper clamping plate 1 and the stop plate 2. A fine adjustment rod 11 is horizontally slidably connected to one side of the top of the upper clamping plate 1, and the contact surface between the pressure rod 10 and the fine adjustment rod 11 is an inclined structure.

[0030] The angle adjustment component includes an arc surface 1201, a triangular groove 1202, a mounting hole 1203, an inclined surface 1401, an arc surface 2 1402, a groove 1403, and a mounting hole 2 1404. The arc surface 1201 is located at one corner of the mold base 3 12, and the triangular groove 1202 is located on one side of the mold base 3 12.

[0031] The mounting hole 1203 and mounting hole 1404 are respectively opened on the opposite side of the mold base 12 and the movable base 14, and the two ends of the spring 13 are fixedly connected to the inner side of the mounting hole 1203 and mounting hole 1404. The arc surface 1402 is opened at one corner of the top of the movable base 14, and the inclined surface 1401 is set at one corner of the movable base 14 away from the arc surface 1402. The inclined surface 1401 is adapted to the bottom end of the pressure rod 10, and the groove 1403 is opened on one side of the movable base 14.

[0032] During operation, the horizontal displacement of the fine-tuning rod 11 pushes the pressure rod 10 downward and vertically. At this time, the bottom end of the pressure rod 10 contacts the bottom inclined surface 1401 of the moving seat 14, and drives the moving seat 14 to move towards the position of the mold base 12. The workpiece 8, which has a 90° angle, located at the top of the mold base 12, is squeezed by one corner of the top of the moving seat 14. The squeezed side of the workpiece 8 fits against the triangular groove 1202, and the spring 13 located between the mounting hole 1203 and the mounting hole 1404 is also squeezed. This promotes the bending angle shaping of the workpiece 8, thereby meeting the customer's requirements for the angle specifications of the sheet metal parts and expanding the applicability of the device.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
