Description

Technical Field

[0001] This utility model relates to the field of bending tool technology, and in particular to a bending tool with automatically adjustable dimensions. Background Technology

[0002] With the continuous development of the manufacturing industry, bending machines have been widely used in many fields such as metal processing, automobile manufacturing, and electrical appliance production due to their ability to efficiently and accurately bend various types of sheet metal. However, at present, there are still some obvious defects in the cutting tool system of bending machines.

[0003] Most conventional bending machines use a fixed cutter design. This design makes it impossible to flexibly adjust the cutter when dealing with workpieces of different shapes, thicknesses and bending angles, which greatly limits the diversity and adaptability of its processing.

[0004] Even some high-end bending machines with tool changing functions have many problems. Their tool changing operation usually requires a complicated process and multiple steps. Operators need to spend a lot of time disassembling, installing and adjusting the tools, which not only reduces production efficiency but also increases labor costs.

[0005] Moreover, the tool changing systems of these high-end bending machines mostly adopt servo control technology. Although servo control systems can achieve precise control to a certain extent, their hardware costs are high, and their software programming and debugging are also relatively complex, which leads to a significant increase in the overall cost of the equipment and increases the company's procurement and operating costs. At the same time, servo control systems are prone to failure during long-term operation, and their stability and reliability are difficult to guarantee effectively. Once a failure occurs, it will lead to the shutdown of the production line and cause significant economic losses to the company. Utility Model Content

[0032] The working principle of this utility model is as follows:

[0033] Before the bending machine starts operating, the user selects the shape, specifications, and quantity of the upper pressure blade, lower pressure blade, and flipping blade according to the model, specifications, size, and number and size of the parts to be bent. The corresponding number of lower pressure blades are detachably fixed one by one to the blade assembly mounting bracket 1 using fasteners to form the lower pressure blade assembly 3. A portion of the upper pressure blades are detachably fixed one by one to the blade slide rail 1.1.1 of the upper pressure blade assembly using fasteners to form the fixed upper pressure blades or fixed upper pressure blades in the upper pressure blade assembly 2. Group 2.2, with another portion of the upper pressing blades movably mounted on the upper pressing blade group blade slide rails 1.1.1 on both sides of the fixed upper pressing blade or the fixed upper pressing blade group 2.2, forming two movable upper pressing blades or movable upper pressing blade groups in the upper pressing blade group 2. The fixed upper pressing blade or the fixed upper pressing blade group 2.2, together with the two movable upper pressing blades 2.1 or the movable upper pressing blade groups, constitutes the upper pressing blade group 2. The blade group adjustment power source 5.2 and the two movable upper pressing blades 2.1 or the movable upper pressing blade groups... The movable upper pressing blade assembly is connected and can push the two movable upper pressing blades 2.1 or the movable upper pressing blade assembly to slide on the upper pressing blade assembly blade slide rail 1.1.1; a portion of the flipping blades are detachably fixed one by one to the flipping blade assembly blade slide rail 1.1.2 with fasteners to form the fixed flipping blades or fixed flipping blade assembly 4.2 in the flipping blade assembly 4; another portion of the flipping blades are movably mounted on the flipping blade assembly blade slide rail 1.1.2 on both sides of the fixed flipping blades or the fixed flipping blade assembly 4.2 to form the two movable flipping blades 4.1 or movable flipping blade assemblies in the flipping blade assembly 4; the fixed flipping blades or the fixed flipping blade assembly 4.2 together with the two movable flipping blades 4.1 or the movable flipping blade assemblies constitute the flipping blade assembly 4; the blade assembly adjustment power source 5.2 is connected to the movable flipping blades 4.1 or the movable flipping blade assembly and can push the movable flipping blades 4.1 or the movable flipping blade assembly to slide on the flipping blade assembly blade slide rail 1.1.2;

[0034] When the bending machine is working, the control program in the bending machine controls the working blades or working blade groups in the upper pressing blade group 2 to press the part to be bent down onto the corresponding working blades or working blade groups in the lower pressing blade group 3, positioning the part to be bent before bending. The corresponding working blades or working blade groups in the flipping blade group 4 bend the part to be bent according to the specific instructions of the control program. The same part to be bent may need to be bent once or more, and the same part to be processed may have two or more parts to be bent. The dimensions of the different parts to be bent may be different, and the dimensions of the working blades or working blade groups need to correspond to the dimensions of the parts to be bent. Different sized parts to be bent require different sized working blades or working blade groups for bending. If the same bending machine needs to bend two or more different sized parts of the workpiece sequentially and continuously, the size of the working blades or working blade groups needs to be automatically adjusted. However, the size of the fixed upper pressing blade or the fixed upper pressing blade group 2.2, the two movable upper pressing blades 2.1 or the movable upper pressing blade group, the fixed flipping blade or the fixed flipping blade group 4.2, and the two movable flipping blades 4.1 or the movable flipping blade group, which are already installed on the blade slide rail 1.1, cannot be changed without stopping the machine to change the blades.

[0035] In this invention, the automatic adjustment of the size of the working blade or working blade group is accomplished by selecting the working blade or working blade group: the working blade in the upper pressing blade group 2 can be the fixed upper pressing blade, or one or both of the two movable upper pressing blades 2.1; the working blade group in the upper pressing blade group 2 can be the fixed upper pressing blade group 2.2, or the fixed upper pressing blade group 2.2 combined with one or both of the two movable upper pressing blades 2.1; the working blade in the flipping blade group 4 can be the fixed flipping blade, or one or both of the two movable flipping blades 4.1; the working blade group in the flipping blade group 4 can be the fixed flipping blade group 4.2, or the fixed flipping blade group 4.2 combined with one or both of the two movable flipping blades 4.1;

[0036] In this invention, the automatic adjustment of the size of the working blade or working blade group is not only reflected in the selection of the working blade or working blade group, but also in the automatic completion of the combination or separation of one or both of the fixed upper pressing blade group 2.2 and the two movable upper pressing blades 2.1 under the control of the upper pressing blade group adjustment power source 5.2.1 in the bending machine, and also in the automatic completion of the combination or separation of one or both of the fixed flipping blade group 4.2 and the two movable flipping blades 4.1 under the control of the flipping blade group adjustment power source 5.2.2 in the bending machine.

[0037] In this invention, under the control of the bending machine's control program, the upper pressure blade group adjusting power source 5.2.1 drives the fixed upper pressure blade group 2.2 to merge or separate from one or both of the two movable upper pressure blades 2.1. Under the control of the bending machine's control program, the flipping blade group adjusting power source 5.2.2 drives the fixed flipping blade group 4.2 to merge or separate from one or both of the two movable flipping blades 4.1. This not only achieves automatic adjustment of the size of the working blade or working blade group, but also enables the bending of the part to be bent when the part to be processed is being bent. That is, when the working blade or working blade group is bending the part to be bent, it avoids the bending of the part to be processed corresponding to the non-working blade, non-working blade group, or other parts.

[0038] The beneficial effects of the technical solution of this utility model of an automatically adjustable bending cutter are as follows: The fixed upper pressure blade group and one or both of the two movable upper pressure blades are combined or separated automatically under the control of the upper pressure blade group's power source and the control program in the bending machine. Similarly, the fixed flipping blade group and one or both of the two movable flipping blades are combined or separated automatically under the control of the flipping blade group's power source and the control program in the bending machine. This achieves automatic selection of the working blade or working blade group. Through the automatic combination and selection of the working blade or working blade group, the bending of two or more different sized parts of the workpiece can be performed sequentially and continuously, greatly reducing the production cost of the bending machine and significantly improving bending efficiency.

[0039] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
