Description

Technical Field

[0001] This application relates to the technical field of presses, and particularly to a precision metal forming press. Background Art

[0002] A press is a versatile press with a delicate structure, featuring wide applications and high production efficiency. It can be widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. By applying a strong pressure to a metal blank, the metal undergoes plastic deformation and fracture to be processed into parts. Precision metal is a metal material with special physical properties (such as magnetic, electrical, thermal, etc.). Currently, when producing and processing precision metal sheets, a press is usually required to apply pressure to a precision metal blank to form it into a precision metal sheet.

[0003] In the related art, during the process of using a press to press and process a precision metal blank into a precision metal sheet, usually an operator takes the precision metal blank and manually places it into the forming cavity of the pressing die, and then presses and forms the placed precision metal blank. This manual feeding operation method not only increases the labor intensity of the operator, increases the labor cost, but also has low work efficiency. Therefore, we propose a precision metal forming press to solve the above problems. Utility Model Content

The bottom of the mounting plate 7 is detachably fixedly installed with a pressing die 8. The pressing die 8 is located directly above the forming cavity 3. The pressing die 8 is adapted to the forming cavity 3. The electric hydraulic cylinder 6 is used to control the vertical lifting of the mounting plate 7 and the pressing die 8, that is, to control the pressing die 8 to enter the inside of the forming cavity 3 for mold closing, or to control the pressing die 8 to move out of the forming cavity 3 for demolding. The pressing die 8 can be fixed to the bottom of the mounting plate 7 by the existing bolt assembly method, which is convenient for disassembling and assembling the pressing die 8 for maintenance.

The conveyor belt 10 is rotatably installed in the U-shaped conveying frame 9. An outlet 11 with an open top is formed on the left side wall of the U-shaped conveying frame 9. The U-shaped guiding plate 12 is fixedly installed on the top of the machine table 1 and is located between the die holder 2 and the U-shaped conveying frame 9. The outlet 11 is communicated with the right side of the U-shaped guiding plate 12. The left side of the U-shaped guiding plate 12 is communicated with the forming cavity 3. The pushing component is arranged on the right side of the U-shaped conveying frame 9. The pushing component is used to push the precision metal blank out of the outlet 11. The conveyor belt 10 is used to convey the precision metal blank. It should be noted that the assembly method and control method of the conveyor belt 10 are mature technical means of the existing technology, so they will not be repeated in this article. The pushing component includes an electric telescopic rod 15 and a pushing plate 16. A receiving groove 13 is formed on the right inner wall of the U-shaped conveying frame 9. A through hole 14 is formed on the right inner wall of the receiving groove 13. The electric telescopic rod 15 is fixedly installed on the right outer wall of the U-shaped conveying frame 9.

The pushing plate 16 is fixedly installed at the output shaft end of the electric telescopic rod 15 and is located in the receiving groove 13. The receiving groove 13 is used to receive and store the pushing plate 16. The electric telescopic rod 15 is used to control the horizontal linear movement of the pushing plate 16. By using the horizontal linear movement of the pushing plate 16, the precision metal blank on the conveyor belt 10 can be pushed out of the outlet 11, and the precision metal blank can enter the inside of the forming cavity 3 through the U-shaped guiding plate 12. A second limiting plate 24 is fixedly installed in the U-shaped conveying frame 9 and is located above the conveyor belt 10. The second limiting plate 24 is used to block and limit the precision metal blank conveyed on the conveyor belt 10. When the precision metal blank abuts against the second limiting plate 24, the precision metal blank is just aligned with the outlet 11.The blank positioning mechanism is arranged on the machine table 1 and is located on the left side of the die base 2. The blank positioning mechanism is used to position the position of the precision metal blank fed into the forming cavity 3. The above-mentioned blank positioning mechanism includes an electric guide rail 17, an electric slide 18, a vertical rod 19, a positioning plate 20, a baffle 21 and a first limiting plate 22.

The electric slide 18 is slidably installed on the electric guide rail 17. The vertical rod 19 is fixedly installed at the bottom of the electric slide 18. The positioning plate 20 is fixedly installed at the bottom end of the vertical rod 19. The right end of the positioning plate 20 extends into the forming cavity 3. The baffle 21 is fixedly installed on the top of the machine table 1 and is located on the left side of the die base 2. The first limiting plate 22 is fixedly installed at the bottom of the positioning plate 20. The first limiting plate 22 abuts against the left side of the baffle 21. By using the horizontal linear sliding of the electric slide 18 on the electric guide rail 17, the vertical rod 19 can be controlled to drive the positioning plate 20 and the first limiting plate 22 to move horizontally in a straight line. By using the positioning plate 20, the position of the precision metal blank entering the forming cavity 3 can be accurately positioned. By using the abutment of the first limiting plate 22 and the baffle 21, the horizontal rightward movement stroke of the positioning plate 20 can be blocked and limited. When the first limiting plate 22 abuts against the baffle 21 and the precision metal blank moves into the forming cavity 3 and abuts against the right side of the positioning plate 20, at this time, the precision metal blank is exactly located in the middle part of the forming cavity 3. Then, the pressing die 8 can be used to accurately press the precision metal blank into shape.,

[0026] In this embodiment, the upper surface of the conveyor belt 10, the bottom inner wall of the U-shaped guiding plate 12 and the bottom inner wall of the forming cavity 3 are located on the same horizontal plane, which can ensure that the precision metal blank is smoothly conveyed into the forming cavity 3.

[0027] In this embodiment, the bottom surface of the positioning plate 20 is higher than the bottom inner wall of the forming cavity 3. The gap between the bottom surface of the positioning plate 20 and the bottom inner wall of the forming cavity 3 is set to be 1-3 mm, which can prevent the positioning plate 20 from contacting the inner wall of the forming cavity 3.

[0028] In this embodiment, a blanking hole 23 is opened on the top of the machine table 1. The blanking hole 23 is located between the die base 2 and the baffle 21. When the operator uses a brush to clean the metal debris inside the forming cavity 3, the swept metal debris can be discharged and fall from the blanking hole 23.

[0029] In this embodiment, it should be noted that the electric hydraulic cylinder 6, the electric telescopic rod 15, the electric guide rail 17 and the electric slide 18 are all purchased on the market. The electric hydraulic cylinder 6, the electric telescopic rod 15, the electric guide rail 17 and the electric slide 18 are equipped with power supplies. Their circuit connection and control methods belong to mature technologies in this field and have been fully disclosed. Therefore, they are not repeated in the specification.

[0030] Through the above structure, the precision metal forming press provided by the present application can realize automatic loading of precision metal blanks when in use, save the labor of operators, reduce labor costs, and improve work efficiency. During specific operation, the precision metal blanks are placed on the conveyor belt 10, and the rotation of the conveyor belt 10 can be used to transport the precision metal blanks in a straight line, so that the precision metal blanks gradually move in a straight line toward the direction close to the limit plate 24. When the precision metal blanks move to the point where they collide with the limit plate 24, the electric telescopic rod 15 is controlled to extend and run, and the electric telescopic rod 15 drives the push plate 16 to gradually move out of the storage groove 13 and move to the left. The push plate 16 is used to move to the left, and the precision metal blanks can be pushed to pass through the discharge port 11 and the U-shaped guide plate 12 in sequence into the forming cavity 3. At the same time, the electric slide 18 is controlled to slide horizontally to the right on the electric guide rail 17, and the electric slide 18 drives the vertical rod 19, the positioning plate 20 and the limit plate 1 22 to move horizontally to the right. When the limit plate 1 22 is right When it moves to the point where it conflicts with the baffle plate 21, the electric slide 18 stops moving. As the push plate 16 is used to push the precision metal blank into the forming cavity 3 and conflicts with the right side of the positioning plate 20, the precision metal blank is accurately delivered to the forming cavity 3. Then the electric telescopic rod 15 is controlled to reset, and the push plate 16 can be controlled to move rightward into the storage groove 13. Then the electric slide 18 is controlled to drive the vertical rod 19, the positioning plate 20 and the limit plate 22 to move horizontally to the left. Then the electric hydraulic cylinder 6 is controlled to extend and operate. The mounting plate 7 and the die 8 are controlled to move vertically downward, so that the die 8 enters the molding cavity 3 for mold closing. The precision metal blank can be press-formed by applying vertical downward pressure to the precision metal blank by the die 8. After press-forming, the mounting plate 7 and the die 8 can be controlled to move vertically upward back to their original positions by controlling the electric hydraulic cylinder 6 to contract and reset. The operator can then take out the press-formed precision metal molded parts. According to the above operating steps, other precision metal blanks can be automatically loaded and press-formed in turn.
