[0002] A mold is a tool used to make molded objects. This tool is made up of various parts, and different molds are made up of different parts. A bending mold refers to a die that bends a blank or semi-finished product into a certain shape. Aviation parts mainly refer to various spare parts of aircraft. Some parts require the use of bending molds for aviation parts processing during processing.

[0003] There are still some problems with the common bending dies used for processing aviation parts. For example, some bending dies used for processing aviation parts can usually only bend the parts to the same angle when processing the parts, and it is not convenient to adjust the angle of the bending plate. This has great limitations on the processing of aviation parts and poor flexibility.

[0004] Therefore, we proposed a bending die for multi-angle aviation parts processing to improve the above problems. Utility Model Content

[0023] The electric push rod 6 is movably hinged at both ends of the top of the lower template 4 and the upper template 10, and the lower template 4 and the upper template 10 cooperate with each other;

[0024] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the parts to be processed are placed on the top of the lower template 4. After placing them, the hydraulic cylinder 7 is started. The hydraulic cylinder 7 drives the upper template 10 to descend so that the upper template 10 rests on the top of the parts, and then the electric push rods 6 on the top of the upper template 10 and the lower template 4 are started at the same time. Since the bending plate 5 is movably hinged on the left side of the lower template 4 and the upper template 10, the electric push rod 6 can drive the left side of the bending plate 5 to rise so that the bending plate 5 bends the parts. The inclination angle of the bending plate 5 can control the bending angle of the parts, thereby improving the flexibility of the mold.

[0025] Embodiment 2: A first mounting plate 9 is installed at the bottom end of the hydraulic cylinder 7, reserved grooves 20 are respectively provided at the top of the upper template 10 and the bottom of the lower template 4, mounting grooves 21 are provided at the four corners of the second mounting plate 11 and the first mounting plate 9, fixing bolts 15 are provided inside the mounting grooves 21, the first mounting plate 9 and the second mounting plate 11 are respectively embedded in the reserved grooves 20, and the mounting grooves 21 are provided at the four corners inside the reserved grooves 20;

[0026] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the upper template 10 and the lower template 4 need to be replaced, the fixing bolt 15 is screwed out of the interior of the mounting groove 21, so that the second mounting plate 11 and the first mounting plate 9 can lose their fixation. If the second mounting plate 11 and the first mounting plate 9 lose their fixation, the lower template 4 and the upper template 10 can be disassembled, and the lower template 4 and the upper template 10 of different shapes can be replaced. When installation is required, the first mounting plate 9 and the second mounting plate 11 are respectively embedded in the reserved groove 20, and then the fixing bolt 15 is screwed into the interior of the mounting groove 21.

[0027] Embodiment 3: The two sides of the bottom end of the workbench 2 are fixedly connected with fixed blocks 3, and the limit rods 13 are fixedly connected between the fixed blocks 3. The two sides of the outside of the limit rod 13 are movably sleeved with sliding sleeves 12, and a spring 18 is fixedly connected between the sliding sleeve 12 and the limit rod 13. The top of the sliding sleeve 12 and the two sides of the bottom end of the second mounting plate 11 are respectively fixedly connected with second mounting blocks 19, and a hinged rod 17 is movably hinged between the second mounting blocks 19. The spring 18 is sleeved on the two sides of the outside of the limit rod 13, and the sliding sleeve 12 and the spring 18 slide on the two sides of the outside of the limit rod 13;

[0028] Specifically, Figure 1 and Figure 3As shown, when the hydraulic cylinder 7 drives the upper template 10 to press against the top of the component, the lower template 4 will squeeze the spring 18 through the hinge rod 17 and the sliding sleeve 12, and the spring 18 will cushion the lower template 4 and the components at the top of the lower template 4 through its own elasticity, thereby protecting the lower template 4 and the upper template 10 and increasing the service life of the lower template 4 and the upper template 10. The limiting rod 13 can limit the sliding sleeve 12 and the spring 18.

[0029] Working principle: When the utility model is in use, the parts to be processed are placed on the top of the lower template 4. After placing them, the hydraulic cylinder 7 is started. The hydraulic cylinder 7 drives the upper template 10 to descend so that the upper template 10 abuts against the top of the parts, and then the electric push rods 6 on the top of the upper template 10 and the lower template 4 are started at the same time. Since the bending plate 5 is movably hinged on the left side of the lower template 4 and the upper template 10, respectively, the electric push rod 6 can drive the left side of the bending plate 5 to rise so that the bending plate 5 bends the parts. The upper template 10 abuts against the top of the parts, which can not only limit and fix the parts to prevent the parts from shifting, but also improve the accuracy of bending. When the hydraulic cylinder 7 drives the upper template 10 to abut against the top of the parts, the lower template 4 will squeeze through the hinge rod 17 and the sliding sleeve 12 The spring 18 is compressed, and the spring 18 will buffer the lower template 4 and the parts at the top of the lower template 4 through its own elasticity, so as to protect the lower template 4 and the upper template 10 and increase the service life of the lower template 4 and the upper template 10. When the upper template 10 and the lower template 4 need to be replaced, the fixing bolt 15 is screwed out of the inside of the mounting groove 21, so that the second mounting plate 11 and the first mounting plate 9 can lose their fixation. When the second mounting plate 11 and the first mounting plate 9 lose their fixation, the lower template 4 and the upper template 10 can be disassembled and replaced with lower templates 4 and upper templates 10 of different shapes. When installation is required, the first mounting plate 9 and the second mounting plate 11 are respectively embedded in the reserved groove 20, and then the fixing bolt 15 is screwed into the inside of the mounting groove 21.
