[0017] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0018] Example 1

[0019] The utility model is a copper alloy thin-wall U-shaped groove punching tooling device, the structure is as follows Figure 1 As shown, it includes a base 4 and a support seat 3, the support seat 3 is arranged on the base 4 and can move on the base 4, a U-shaped groove II9 is ​​arranged on the top of the base 4, a punch 1 is arranged in the U-shaped groove II9, and the punch 1 can move up and down in the U-shaped groove II9, so as to punch the copper alloy thin-walled parts 13 to be punched to form a U-shaped groove, and a support body 2 is arranged on the inner wall of the base 4, the support body 2 cooperates with the support seat 3, the support body 2 is used to fix the copper alloy thin-walled parts 13 to be punched and cooperate with the punch 1 to form a U-shaped groove. When in use, the end of the support body 2 away from the base 4 is stuck in the support seat 3 for fixation and axially supports the copper alloy thin-walled parts 13 to be punched to avoid axial movement.

[0020] Example 2

[0021] On the basis of Example 1, the support body 2 includes a cylinder 6, one end of the cylinder 6 is connected to the inner wall of the base 4, and the other end of the cylinder 6 is connected to the cube 7. The cylinder 6 is used to sleeve and fix the copper alloy thin-walled parts 13 to be punched. A U-shaped through groove I5 is provided on the cylinder 6. The U-shaped through groove I5 is used to punch a U-shaped groove for the copper alloy thin-walled parts 13 to be punched. The U-shaped groove can be punched on one side or on both sides. The two punched U-shaped grooves are symmetrically arranged and can facilitate the blanking of residual materials. The U-shaped through groove I5 and the U-shaped groove II9 are arranged correspondingly to ensure that the punch 1 can enter the U-shaped through groove I5 for punching when punching downward. The diagonal length of the cube 7 is not greater than the diameter of the cylinder 6, which can ensure that the copper alloy thin-walled parts 13 to be punched can pass through the cube 7 smoothly and be sleeved on the cylinder 6.

[0022] The support seat 3 includes an L-shaped seat body 12, and a groove 8 is opened on the vertical end of the L-shaped seat body 12. The groove 8 cooperates with the cube 7. When punching, the cube 7 is inserted into the groove 8, and the end of the groove 8 is pressed against the end of the cylinder 6, thereby axially pressing the copper alloy thin-walled parts 13 to be punched. The horizontal end of the L-shaped seat body 12 is arranged toward the support body 2, and the height of the horizontal end of the L-shaped seat body 12 is less than the distance between the bottom end of the cylinder 6 and the base 4, so as to avoid the horizontal end of the L-shaped seat body 12 from rubbing against the copper alloy thin-walled parts 13 to be punched during the installation of the groove 8 and the cube 7.

[0023] Example 3

[0024] On the basis of Example 2, the punch 1 includes a top plate 10, which is convenient for punching by the punch press. A U-shaped punch body 11 is provided at the bottom of the top plate 10. The U-shaped punch body 11 is inserted into the U-shaped groove II9. The U-shaped punch body 11 cooperates with the U-shaped through groove I5. The U-shaped punch body 11 is used to punch the copper alloy thin-walled parts 13 to be punched.

[0025] The working process of the copper alloy thin-wall U-shaped groove punching tooling device of the utility model is as follows: the copper alloy thin-walled parts 13 to be punched are loaded onto the cylinder 6 through the square body 7 ( Figure 2 The D direction is the loading direction of the copper alloy thin-walled parts 13 to be punched), and the punch 1 is placed vertically into the U-shaped through groove II9 ( Figure 2 The direction A in the middle is the direction in which the punch 1 is installed), and the support seat 3 is installed into the base 4 ( Figure 2 The direction B in the middle is the direction of loading the support seat 3), ensure that the cube 7 is inserted into the groove 8, and adjust the position of the support seat 3 so that the vertical end of the support seat 3 is stuck on the top of the cylinder 6 to support the copper alloy thin-walled parts 13 to be punched, and prevent the copper alloy thin-walled parts 13 to be punched from axial movement. Use the punch press to vertically punch the punch 1 downward ( Figure 2The E direction is the punching direction of the punch press), so that the punch 1 can punch the copper alloy thin-walled parts 13 to be punched, and the residual material falls vertically downward through the U-shaped slot I5 ( Figure 2 The C direction is the punching direction of the punch press), after the punching is completed, the punch head 1 is separated from the copper alloy thin-walled part 13 to be punched vertically upward, the support seat 3 is separated from the support body 2 horizontally, and the copper alloy thin-walled part 13 to be punched is separated from the support body 2 horizontally, and the copper alloy thin-walled part 13 to be punched is separated from the support body 2. Figure 3 The copper alloy thin-walled parts with U-shaped grooves are shown. Figure 4 For copper alloy thin-walled parts without U-shaped grooves, Figure 3 and Figure 4 In contrast, after the U-shaped groove was punched out by the punching fixture of the utility model, the copper alloy thin-walled parts did not deform or ablate, and the product quality was guaranteed.
