Detailed Implementation
[0019] The present invention will be further described below with reference to some specific embodiments.
[0020] Example 1
[0021] See Figure 1 A single-ear bending assembly includes a single-ear bending male mold, a single-ear bending female mold, and a positioning plate 3. The single-ear bending female mold includes a single-ear bending female mold body 2. A semi-clamp plate positioning groove 5 and a single-ear clearance groove 6 are formed on the single-ear bending female mold body 2. The single-ear clearance groove 6 is perpendicularly connected to the semi-clamp plate positioning groove 5 and both are square grooves. A semi-clamp plate clearance groove 4 is formed inside the semi-clamp plate positioning groove 5 on the side near the single-ear clearance groove 6. A single-ear bending groove 7 is provided at the junction of the semi-clamp plate clearance groove 4 and the single-ear clearance groove 6. The single-ear bending groove 7 is the area for single-ear bending. The positioning plate 3 is detachably connected to the single-ear bending female die body 2. It is used to fix the half-clamp plate 16 in the half-clamp plate positioning groove 5 and the single-ear clearance groove 6 and to position the half-clamp plate bending position. The single-ear bending male die includes the single-ear bending male die body 1. The upper end of the single-ear bending male die body 1 is cubic in shape and can be clamped by the upper clamping plate of the stamping machine. The end is provided with a bending stamping head 10 that matches the single-ear bending groove 7 to perform single-ear stamping bending of the half-clamp plate 16. The half-clamp plate clearance groove 4 is concave to prevent the half-clamp plate 16 from flipping up during stamping, causing its straight section to collide with the single-ear bending female die body and crack. The half-clamp plate positioning groove 5 cooperates with the positioning plate 3 to position the half-clamp plate bending position and fix the half-clamp plate. The single-ear clearance groove 6 is the position for placing the single ear of the half-clamp plate during stamping, and at the same time, it prevents cracking when the single ear bends up during the stamping process.
[0022] Furthermore, the positioning plate 3 has strip-shaped holes 8 at both ends, and the single-ear bending female mold body 2 has threaded holes that match the strip-shaped holes 8. The positioning bolt 9 passes through the strip-shaped holes 8 and is threaded into the threaded holes. The positioning plate 3 can be moved back and forth to adjust its position on the single-ear bending female mold body 2 to accommodate the position fixing of semi-clamp plates of different widths, thus improving the adaptability of the assembly.
[0023] Furthermore, the depth of the single-ear bending groove 7 is greater than the thickness of the semi-clamp plate 16. This ensures a smooth transition when the single ear bends during the stamping process.
[0024] Furthermore, the end face of the single-ear bending groove 7 is V-shaped, and the connection between the inclined surfaces on both sides of the single-ear bending groove and the bottom of the single-ear bending groove is rounded. The length of the inclined surface of the single-ear bending groove 7 is equal to the width of the single-ear clearance groove 6. The single-ear bending male mold bends the semi-clamp plate into shape in one go, ensuring that the bending angle tends to the target shape requirement, optimizing the stress on the outer side of the bending position of the semi-clamp plate, and thus making the bending position smooth transition.
[0025] Furthermore, the single-ear clearance groove 6 and the semi-locking ring plate positioning groove 5 have the same depth, which facilitates the placement of the semi-locking ring plate 16.
[0026] The method of using the single-ear bending component of this utility model is as follows: See Figure 3Before the single-ear bending operation, select the appropriate single-ear bending male and female dies according to the specifications of the half-ear clasp. First, clamp the single-ear bending male and female dies on the stamping table simultaneously. Then, place the half-ear clasp plate 16 in the half-ear clasp plate positioning groove 5 on the female die and position it with the positioning plate 3. Use the positioning bolt 9 to pass through the strip hole 8 on the positioning plate 3 and connect it with the threaded hole on the single-ear bending female die body 2. The lower end face of the positioning plate 3 is completely attached to the threaded hole of the single-ear bending female die. Finally, use the single-ear bending male die to vertically punch the single-ear bending female die to obtain the single-ear bent half-clasp 17.
[0027] Example 2
[0028] A single-ear half-clamping ring stamping die includes the single-ear bending assembly described in Example 1.
[0029] Further, see Figure 2 The stamping die also includes a semi-clamping ring arc stamping assembly, which includes a semi-clamping ring arc stamping male die and a semi-clamping ring arc stamping female die. The semi-clamping ring arc stamping female die includes a semi-clamping ring arc stamping female die body 13. The top surface of the semi-clamping ring arc stamping female die body 13 has an arc forming groove 14, and the end surface has a single ear placement groove 15. The single ear placement groove 15 is a square groove, and the top of the single ear placement groove 15 is connected to the bottom of the arc forming groove 14. The semi-clamping ring arc stamping male die includes a semi-clamping ring arc stamping male die body 11. The upper end of the semi-clamping ring arc stamping male die body 11 is cubic in shape, which can be clamped by the upper clamping plate of the stamping machine. The end of the semi-clamping ring arc stamping male die body 11 is provided with an arc stamping head 12 that matches the arc forming groove 14 to perform arc stamping forming of the center of the semi-clamping ring.
[0030] The method of using the single-ear half-clamp ring stamping die of this utility model is as follows: See Figure 3 The single ear is bent using the single-ear bending assembly described in Example 1 to obtain a bent half-clamp 17. The method and steps are the same as in Example 1. Then, the bent half-clamp 17 is formed by arc stamping using a half-clamp arc stamping assembly. (See Example 1 for details.) Figure 4 Before stamping the semi-clamp ring arc, select the appropriate semi-clamp ring arc stamping male die and semi-clamp ring arc stamping female die according to the semi-clamp ring specifications, and clamp them simultaneously on the stamping table. Place the semi-clamp ring 17 after bending the single ear into the stamping position, with the single ear facing down, and insert it into the single ear placement groove 15. Then, stamping can be performed directly to obtain the single ear semi-clamp ring 18.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
