Description

Technical Field

[0001] This utility model belongs to the field of workpiece processing technology, and specifically relates to a bending device. Background Technology

[0002] Workpiece machining is an indispensable part of manufacturing, involving every stage from raw materials to finished products. It not only determines the final quality and performance of products but also directly impacts a company's production efficiency and competitiveness. With technological advancements, workpiece machining is constantly evolving, with new processing methods and equipment emerging continuously, propelling the manufacturing industry towards higher levels.

[0003] Bending workpieces into arc shapes is a common processing requirement. One commonly used method in existing technologies is the stretch bending process. Stretch bending refers to bending a workpiece into shape by applying tensile force. However, the stretch bending process also has some limitations and potential problems. During stretch bending, certain areas of the workpiece may experience stress concentration due to uneven force distribution. This stress concentration in certain weak areas may lead to localized deformation or cracking of the material. Stretch bending processes often struggle to achieve a uniform tensile force distribution. Due to uneven tensile force distribution, different parts of the workpiece may deform to varying degrees, affecting the consistency and precision of the finished product and leading to defective products. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, the technical problem to be solved by this utility model is to propose a bending device that, by setting up an assembly unit and a bending unit on the operating table, and by having the moving mold in the bending unit drive the arc-shaped pressure block to cooperate with the arc-shaped workstation, can uniformly apply pressure during the bending operation of the workpiece, avoid local stress concentration, thereby better control of the workpiece deformation process and significantly reduce the generation of defective products.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a bending device for assembling inserts onto a workpiece and bending the assembled workpiece into shape. The bending device includes:

[0006] Control panel;

[0007] An assembly unit is disposed on the operating table and has a positioning component and a moving component. The positioning component and the moving component are disposed opposite to each other, and the moving component is movable relative to the positioning component. The workpiece is placed on the positioning component, and the insert is placed on the moving component. The positioning component is used to provide positioning for the workpiece, and the moving component is used to assemble the insert onto the workpiece.

[0008] A bending unit is disposed to the side of the assembly unit and has a moving mold and a fixed mold. The moving mold is movably disposed above the fixed mold. An arc-shaped station is provided on the fixed mold. An arc-shaped pressure block is provided on the moving mold opposite to the arc-shaped station. The assembled workpiece is placed on the arc-shaped station, and the arc-shaped pressure block is used to bend the workpiece.

[0009] In the aforementioned bending device, the bending unit further includes a first driving member, which is disposed on the operating table.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] like Figure 1 As shown, a bending device in this solution is used to assemble inserts onto a workpiece and bend the assembled workpiece into an arc shape.

[0031] like Figures 1 to 5 As shown, this solution provides a bending device, comprising: an operating table 1; an assembly unit 2, which is disposed on the operating table 1 and has a positioning component 3 and a moving component 4, the positioning component 3 and the moving component 4 being arranged opposite to each other, and the moving component 4 being movable relative to the positioning component 3, the workpiece being placed on the positioning component 3, and the insert being placed on the moving component 4, the positioning component 3 being used to provide positioning for the workpiece, and the moving component 4 being used to assemble the insert onto the workpiece; and a bending unit 5, which is disposed to the side of the assembly unit 2 and has a moving mold 6 and a fixed mold 7, the moving mold 6 being movably disposed above the fixed mold 7, the fixed mold 7 having an arc-shaped station 8, the moving mold 6 having an arc-shaped pressing block 9 arranged opposite to the arc-shaped station 8, the assembled workpiece being placed on the arc-shaped station 8, and the arc-shaped pressing block 9 being used to bend and shape the workpiece on the arc-shaped station 8.

[0032] During operation, the workpiece and insert are first placed on the positioning component 3 and the moving component 4, respectively. After placement, the moving component 4 moves the insert closer to the workpiece until it is assembled onto the workpiece. Next, the assembled workpiece can be placed on the arc-shaped station 8 by a worker or automated equipment for subsequent bending operations. After the workpiece is placed on the arc-shaped station 8, the moving mold 6 moves the arc-shaped pressure block 9 closer to the arc-shaped station 8 until it contacts the workpiece and applies appropriate force. Under the pressure of the arc-shaped pressure block 9, the workpiece gradually bends from a straight line into a curved shape. The bending process is completed by adjusting the workpiece to the required arc shape. During this process, the moving mold 6 in the bending unit 5 drives the arc-shaped pressure block 9 to work in conjunction with the arc-shaped station 8. This allows for the uniform application of pressure to the workpiece during bending, avoiding localized stress concentration and thus better controlling the deformation process of the workpiece, significantly reducing the production of defective products. In addition, integrating the assembly unit 2 and the bending unit 5 onto a single operating table 1 reduces intermediate transfer links, simplifies the production process, and the compact design not only improves space utilization but also optimizes equipment layout, facilitating maintenance and operation, and enhancing overall production efficiency.

[0033] Furthermore, the bending unit 5 also includes a first drive member 11, which is mounted on the operating table 1. The moving mold 6 is connected to the output end of the first drive member 11. The first drive member 11 is used to drive the moving mold 6 to move in the vertical direction. The first drive member 11 is preferably a feed-type servo electric cylinder, which is a modular product that integrates a servo motor and a lead screw. It can convert the rotary motion of the servo motor into linear motion. "Feed-type" means that the electric cylinder is used to precisely control the feed speed and position of the tool or workpiece. Due to the use of a servo motor, the feed-type servo electric cylinder can achieve very high positioning accuracy and repeatability, and can quickly respond to changes in commands, making it suitable for high-speed applications. In high-acceleration applications, this high-precision and fast-response characteristic ensures that the moving mold 6 can move precisely along the preset path during the bending process, thereby ensuring the consistency and reliability of each bending operation. In addition, by programming with a PLC or other control system, parameters such as stroke, speed and output force can be flexibly adjusted to adapt to the bending requirements of workpieces of different specifications. The first driving component 11 drives the arc-shaped pressure block 9 to bend the workpiece through the moving mold 6, ensuring that pressure is applied evenly through the precise control of the servo electric cylinder throughout the bending process, avoiding local stress concentration, better controlling the deformation process of the workpiece, and significantly reducing the generation of defective products.

[0034] Furthermore, a support frame 10 is provided on the moving mold 6, and the arc-shaped pressure block 9 is connected to the support frame 10. The support frame 10 is mainly used to enhance the structural rigidity of the moving mold 6 and ensure that the arc-shaped pressure block 9 can move smoothly in the vertical direction. The support frame 10 is made of high-strength material and has good rigidity and stability to ensure that no deformation or vibration occurs during the bending process.

[0035] Furthermore, a first clamping block 12 is fixed on one side of the arc-shaped workstation 8, and a second clamping block 13 is movably arranged on the other side. The two ends of the assembled workpiece abut against the first clamping block 12 and the second clamping block 13 respectively, for fixing the workpiece.

[0036] Furthermore, the arc-shaped workstation 8 is also equipped with an elastic element 14 and a fixing block 15. One end of the elastic element 14 abuts against the second pressing block 13, and the other end abuts against the fixing block 15.

[0037] The bending operation for the assembled workpiece is as follows: First, bring one end of the assembled workpiece close to and press it against the second clamping block 13. At this time, because the workpiece applies a force to the second clamping block 13, the elastic element 14 is compressed and generates a reverse elastic force. Next, place the other end of the workpiece on the arc-shaped station 8. Due to the reverse elastic force of the elastic element 14, the second clamping block 13 will automatically adjust its position, so that the other end of the workpiece is in close contact with the first clamping block 12, thereby achieving effective fixation of both ends of the workpiece. At this time, the two ends of the assembled workpiece are respectively against the first clamping block 12 and the first clamping block 13. The second clamping block 13 clamps the workpiece, and there is a suspended space between the workpiece and the arc-shaped station 8. Subsequently, the first driving component 11 is activated, driving the moving mold 6 and the support frame 10 on it to move closer to the fixed mold 7. The arc-shaped pressure block 9 moves closer to the workpiece on the arc-shaped station 8 under the drive of the support frame 10 until it contacts the workpiece and applies appropriate pressure to the workpiece, so that the workpiece is gradually bent from a straight line into the required arc shape. During this process, the suspended space between the workpiece and the arc-shaped station 8 provides the necessary bending space to ensure that the workpiece can successfully complete the bending and forming operation. The elastic component 14 is preferably a spring.

[0038] Furthermore, a support base 16 is also provided on the operating table 1, and the positioning component 3 and the moving component 4 are both provided on the support base 16.

[0039] In order to move the movable part 4, a second driving part 17 is also provided on the operating table 1, which is located below the support base 16; in order to connect the movable part 4 and the second driving part 17, a hollow part 18 is provided on the support base 16, and one side of the movable part 4 passes through the hollow part 18 and connects with the second driving part 17.

[0040] The specific operation of assembling the insert onto the workpiece is as follows: First, the workpiece is placed on the positioning part 3, and the insert is placed on the moving part 4. At this time, the workpiece and the insert are in a relatively set position. Then, the second driving part 17 is activated, and the moving part 4 is driven to move towards the positioning part 3 through the hollow part 18. The moving part 4 moves precisely close to the workpiece on the positioning part 3 along the path of the hollow part 18. When the moving part 4 approaches the workpiece on the positioning part 3, the insert gradually approaches and is finally assembled onto the workpiece. During this process, the second driving part 17 ensures that the movement of the moving part 4 is smooth and precise, thereby achieving a high-quality assembly effect. Through this design, the workpiece and the insert can be assembled accurately and without error, ensuring the smooth progress of the subsequent bending process. The second driving part 17 can be a motor, a hydraulic cylinder, or a pneumatic cylinder.

[0041] In order to fix the workpiece placed on the positioning member 3, a third abutting block 19 is also movably provided on the side of the support base 16, and abutting part 20 is provided on one side of the positioning member 3. The two ends of the workpiece abut against the third abutting block 19 and the abutting part 20 respectively, for fixing the workpiece.

[0042] In order to move the third clamping block 19, a third driving component 21 is also provided on the operating table 1, and the third clamping block 19 is connected to the output end of the third driving component 21.

[0043] When the workpiece to be assembled is placed on the positioning component 3, the third drive component 21 first moves the third abutting block 19 away from the positioning component 3 to make room for the workpiece. Then, the workpiece is placed on the positioning component 3, ensuring that one end of the workpiece contacts the abutting part 20 on the positioning component 3. After the workpiece is placed on the positioning component 3, the third drive component 21 starts again, moving the third abutting block 19 closer to the workpiece on the positioning component 3 until the third abutting block 19 is in close contact with the other end of the workpiece. At this time, both ends of the workpiece are abutted against the positioning part on the positioning component 3 and the third abutting block 19 respectively, thus ensuring that the workpiece is firmly fixed on the positioning component 3, preparing for the subsequent strip assembly. Through this design, the workpiece can maintain a stable position throughout the strip assembly process, ensuring a high-quality assembly effect. The third drive component 21 can be a motor, hydraulic cylinder, or pneumatic cylinder.
