[0002] In the production of automobile parts, flanging is a common process. Flanging refers to a molding method that uses the function of a mold on the flat part or curved part of the part to be processed to form a straight wall or flange with a certain angle along the edge of a closed or unclosed curve. Different molds are composed of different parts, and the processing of the shape of the object is mainly achieved by changing the physical state of the molded material. There is a problem of inconvenience in processing and flanging automobile parts.

[0003] In the prior art, CN213701335U discloses a flanging mold for automotive parts. When in use, the parts are placed on the lower mold, and the push rod motor is started to drive the first movable plate and the upper mold to move toward the lower mold. The parts to be processed are fixed by the cooperation of the upper mold and the lower mold. The first movable plate continues to move the compression spring, and the first movable plate drives the pressure rod to continue to move. The pressure rod squeezes the sliding plate, and the sliding plate drives the wire rope and the second movable plate to move. The second movable plate drives the fixed platform to move upward to process the parts to be processed, which solves the problem that the physical state of the mold cannot be changed after forming, which is inconvenient for flanging automotive parts.

[0004] However, in the above structure, after the stamping and flanging is completed, the parts are easily stuck on the mold, which makes it inconvenient for operators to take them out, thereby reducing the work efficiency of the operators. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] First embodiment

[0022] See also Figure 1 to Figure 3 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 It is a cross-sectional view of the overall structure of the first embodiment of the utility model. Figure 3 yes Figure 1 Enlarged view of point A in the middle.

[0023] The utility model provides a stamping and flanging die for automobile parts: comprising a base 101, a plurality of mounting frames 102, a workbench 103 and a demoulding mechanism, wherein the demoulding mechanism comprises a lower die 104, a driving assembly, a mounting plate 105, a plurality of springs 106, a connecting plate 107, a push block 108, two supporting plates 109, two electric telescopic rods 110 and two clamping plates 111, and the driving assembly comprises a first cylinder 112 and a first piston rod 113. The above scheme solves the problem that the parts after flanging are easily stuck on the die, which makes it inconvenient for operators to take them out, thereby reducing work efficiency.

[0024] According to a specific implementation, the plurality of mounting frames 102 are fixedly connected to the base 101 and are located above the base 101; the workbench 103 is fixedly connected to the base 101 and is located between the plurality of mounting frames 102; holes are provided on the workbench 103; the base 101 is used to support the mounting frames 102 and the workbench 103; and the workbench 103 is used to place a demolding mechanism.

[0025] The driving assembly is fixedly connected to the workbench 103 and is located inside the workbench 103. The mounting plate 105 is fixedly connected to the output end of the driving assembly and is located above the driving assembly. The spring 106 is fixedly connected between the mounting plate 105 and the connecting plate 107. A plurality of push blocks 108 are fixedly connected to the connecting plate 107 and are located above the connecting plate 107. When flanging parts of different specifications, the parts to be flanged are placed above the lower mold 104. The driving assembly is operated to drive the mounting plate 105, the spring 106, and the connecting plate 107 and the push block 108 move vertically upward and rise to a suitable height. The spring 106 is in an extended state. The outer edge of the component is deformed during the flanging process. During the deformation process, the outer edge of the component will squeeze the push block 108 to compress the spring 106. By continuously applying pressure, the edge of the component is shaped. At this time, the pressure is stopped. During the pressure process, the spring 106 is always in a compressed state. After the pressure is stopped, the spring 106 stretches under the action of elasticity, driving the push block 108 to move vertically upward, pushing the component stuck on the lower mold 104 after the flanging is completed to separate the component from the lower mold 104, thereby completing the demoulding of the component.

[0026] Among them, the two electric telescopic rods 110 are fixedly connected to the workbenches 103 respectively and are located above the workbenches 103, and the two electric telescopic rods 110 are opposite to each other, and the two clamps 111 are fixedly connected to the output ends of the electric telescopic rods 110 respectively and are located above the workbenches 103. Through the operation of the electric telescopic rods 110, the clamps 111 move horizontally toward the lower mold 104 to clamp the parts stuck on the lower mold 104, thereby preventing the push block 108 from pushing the parts away from the workbench 103 when the elastic force of the spring 106 is too large, thereby damaging the parts.

[0027] The outer side wall of the lower mold 104 is provided with the scale 114 in the vertical direction. The scale 114 is convenient for operators to accurately grasp the length of the flanging, thereby improving practicality.

[0028] Among them, the first cylinder 112 is fixedly connected to the workbench 103 and is located inside the workbench 103, one end of the first piston rod 113 is movably connected to the first cylinder 112 and is located inside the first cylinder 112, and the other end of the first piston rod 113 is fixedly connected to the mounting plate 105. Through the operation of the first cylinder 112, the first cylinder 112 and the first piston rod 113 cooperate to drive the mounting plate 105, the spring 106, the connecting plate 107 and the push block 108 to move vertically upward, and stop and maintain when they rise to a suitable height. The spring 106 is compressed and then stretched to drive the push block 108 to move vertically upward, so that the parts are separated from the lower mold 104, which is convenient for the operator to take out the parts, thereby improving the operator's work efficiency.
