Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plate processing and relates to a novel bending tool. Background Art
[0002] Traditional integral profiled structures have long dominated the domestic press-bending tooling market, but their inherent flaws have gradually become apparent, becoming a bottleneck restricting the industry's development. Not only is the integral profiled tooling complex, increasing the difficulty of manufacturing and maintenance, but the strict alignment of the profiled plate length with the product length also leads to material waste and increased costs. More critically, the integral profiled structure prevents the effective release of internal stress within the product, resulting in rebound after a certain period of time, seriously affecting the product's precision and stability. Utility Model Content
[0003] The purpose of the present utility model is to provide a new bending tool that can fix products conveniently and quickly. The tool only needs to place the product on the tool, and adopts a bending method from the middle to both ends to divide the internal stress of the product into two parts and push it to both ends to release it, thereby ensuring that the curvature of the product does not change. The product is bent according to a certain curvature by a roller so that the obtained product is consistent with the theoretical data.
[0004] The purpose of the utility model can be achieved through the following technical solutions:
[0005] A bending tool, comprising:
[0006] A base plate, a pressing module and a propulsion module arranged on the base plate;
[0007] The pressing module is used to fix the product, including a third cylinder, a positioning block is provided below the third cylinder, and the positioning block is fixed to the bottom plate. The positioning block can ensure the accurate position of the product in the tooling and prevent the product from being displaced during the processing;
[0008] A support plate is also provided on the bottom plate. The upper edge of the support plate has a curvature, which is consistent with the curvature of the product to be bent. The positioning block and the support plate are used to place the product to be bent.
[0009] The propulsion module is used to bend products and includes a first cylinder, a second cylinder and a slide rail device. The slide rail device includes a track and a slide seat sliding on the track. One end of the first cylinder is fixedly connected to a mounting plate, and the mounting plate is arranged on the slide seat. The second cylinder is fixedly connected to the mounting plate and the telescopic end points to the upper edge of the support plate. The first cylinder is parallel to the track. The first cylinder is used to push the second cylinder to move on the slide rail device, and the second cylinder is used to press the product on the support plate.
[0010] Furthermore, a mounting groove is provided on the slide seat, and the mounting plate is vertically inserted into the mounting groove.
[0011] Furthermore, when designing the support plate, the curvature of the support plate should be consistent with the theoretical data of the product, and the design can be carried out according to the theoretical data of the product.
[0012] Furthermore, the first, second, and third cylinders are large-diameter guide rod cylinders, each with a diameter of 25-40 mm, preferably 32 mm. This type of cylinder prevents deformation of the cylinder rod during movement, thus protecting the cylinders. The third cylinder is used to compress the product and prevent it from moving. The second cylinder works in conjunction with the first cylinder to achieve more complex propulsion and positioning functions.
[0013] Furthermore, if the product is harder, a cylinder with a larger cylinder diameter can also be used.
[0014] Furthermore, a positioning pressing block is provided between the third cylinder and the positioning block for fixing the product. The positioning block, the third cylinder and the positioning pressing block are fixedly connected by screws.
[0015] Furthermore, the positioning block, support plate and positioning pressure block are respectively a No. 1 steel positioning block, a No. 1 steel support plate and a No. 1 steel positioning pressure block.
[0016] Furthermore, the track is arranged obliquely along the upper edge of the support plate.
[0017] Furthermore, the second cylinder also includes a roller, which is connected to the telescopic end of the second cylinder. The roller is installed on the connecting plate of the second cylinder and fixed by screws. The roller is used to roll on the support plate and the product.
[0018] Furthermore, the slide rail device also includes a baffle, a limit block and a bracket. The baffle and the limit block are arranged at both ends of the track. The baffle is used to fix the track, and the bracket is fixed to the bottom of the base plate.
[0019] Furthermore, an arc-shaped groove is provided on the mounting plate, and a connecting rod is provided at the rear of the second cylinder, which is movably connected to the arc-shaped groove. The fixed connection between the second cylinder and the mounting plate serves as the rotation center for adjusting the angle. The arc-shaped groove and the connecting rod are used to adjust the angle between the second cylinder and the surface of the support plate to be close to 90 degrees. The angle is manually adjusted so that during the bending process, the telescopic end of the second cylinder is almost perpendicular to the upper edge of the support plate, which is convenient for the roller to move on it. The roller will start to move along the trajectory of the upper edge of the support plate, and always keep the roller stuck to the support plate. When it is in a nearly vertical state, the thrust of the second cylinder can be fully utilized to ensure the pressure required for bending.
[0020] Furthermore, the bending tool also includes a controller and a power supply connected to the base plate, and the first cylinder, the second cylinder and the third cylinder are electrically connected to the controller; the controller is electrically connected to the power supply. In the working state, the controller causes the third cylinder to operate and fix the product. After the fixation is completed, the second cylinder begins to extend until it presses on the surface of the product. After 2-3 seconds of pressing on the product, the first cylinder begins to push the second cylinder to move. The telescopic length of the second cylinder changes with the fluctuation of the arc surface of the support plate, thereby causing the roller to start moving on the support plate. The arc surface of the support plate is parallel to the arc surface of the product. When the roller moves to the end position of the product, it contacts the limit block and stops moving. After 10 seconds, the second cylinder, the first cylinder and the third cylinder are reset in turn.
[0021] Furthermore, the controller is a PCL controller.
[0022] The new bending tool in the utility model changes its traditional overall pressing design structure. The working principle of the new bending tool is: the product is placed on the positioning block, and the first cylinder, the second cylinder and the third cylinder are electrically connected to the PCL controller. First, the third cylinder is used to press the product to ensure that the product does not move; then the second cylinder drives the roller to press the product, and the telescopic movement of the second cylinder changes with the fluctuation of the arc surface. When pressing the product, the second cylinder is always in an extended state, and the cylinder air pressure is 0.3Mpa; if the arc surface of the support plate is convex, the second cylinder will retract, otherwise it will extend outward to ensure that the roller moves on the support plate; the first cylinder is responsible for pushing the second cylinder to move, to ensure that the second cylinder can press the product in all directions.

A support plate 3 is also provided on the bottom plate 11. The upper edge of the support plate 3 has a curvature, and the curvature of the support plate 3 is consistent with the theoretical data of the product. , it can be designed according to the theoretical data of the product.

The slide rail device includes a track 10 tilted along the upper edge of the support plate 3, a baffle 13, a limit block 9, a bracket 12 and a slide seat sliding on the track 10. The baffle 13 and the limit block 9 are arranged at both ends of the track 10. The baffle is used to fix Track, bracket 12 is fixed to the bottom of the base plate 11, one end of the first cylinder 1 is fixedly connected to the mounting plate 8, a mounting groove is provided on the slide, the mounting plate 8 is vertically inserted into the mounting groove, the second cylinder 4 is fixedly connected to the mounting plate 8 and the telescopic end points to the upper edge of the support plate 3, the telescopic end is provided with a roller 6 for rolling on the support plate 3 and the product, wherein the roller 6 is mounted on the connecting plate of the second cylinder and fixed by screws; an arc groove is also provided on the mounting plate 8, and a connecting rod is provided at the rear of the second cylinder 4, which is movably connected to the arc groove, and the arc groove and the connecting rod are used to Adjust the angle between the second cylinder 4 and the surface of the support plate 3. The fixed connection between the second cylinder 4 and the mounting plate 8 serves as the rotation center for adjusting the angle. The angle is manually adjusted so that during the bending process, the telescopic end of the second cylinder 4 is set nearly perpendicular to the upper edge of the support plate 3. That is, the angle between the second cylinder and the support plate surface is close to 90 degrees, which facilitates the movement of the roller 6 on it. The roller 6 will begin to move along the trajectory of the upper edge of the support plate 3, always keeping the roller 6 firmly attached to the support plate 3. When it is in a nearly vertical state, the thrust of the second cylinder 4 can be fully utilized to ensure the pressure required for bending. The first cylinder 1 is parallel to the track 10.

After 2-3 seconds after pressing against the product, the first cylinder 1 starts to push the second cylinder 4 to move.

When the product is pressed, the second cylinder 4 is always in the extended state, and the cylinder pressure is 0.3Mpa; if the arc surface of the support plate 3 is convex, the second cylinder 4 will retract, otherwise it will extend outward, thereby causing the roller 6 to move on the support plate 3. The arc surface of the support plate 3 is parallel to the arc surface of the product. When the roller 6 moves to the end position of the product, it contacts the limit block 9 and stops moving. After 10 seconds, the second cylinder 4, the first cylinder 1 and the third cylinder 7 are reset in sequence.

Specifically: at the beginning, the product is placed on the positioning block 2 and the support plate 3, and the product is tightly attached to the positioning block 2 and the support plate 3 to ensure the accuracy of the product bending. After the product is placed, turn on the power switch, and the third cylinder 7 on the positioning block 2 will move first to press the product to prevent it from moving; after the product is fixed, the second cylinder 4 drives the roller 6 to move downward until it is close to the surface of the support plate 3 to press the surface of the product first. After a delay of 2-3 seconds, the first cylinder 1 begins to push the second cylinder 4 from the left end of the track 10 to the right end. The roller begins to move along the curved surface of the support plate 3, and the product under the roller also begins to deform until it reaches the stop block 9 and stops. To prevent the product from rebounding, the lifting time of the second cylinder 4 is delayed by about 10 seconds. After 10 seconds, the second cylinder 4 resets first, followed by the first cylinder 1, and finally the third cylinder 7 above the positioning block resets. The product is removed and the next round of work begins.
