Detailed ways

Below in conjunction with accompanying drawing, illustrate the specific embodiment of the present utility model.

As shown in Figure 1, Figure 2 and Figure 3, the bending heel structure of this embodiment includes an upper mold assembly and a lower mold assembly. The structure of the upper mold assembly is: including an upper backing plate 1 connected at the bottom Punch fixed plate 3, punch 2 is installed on the punch fixed plate 3, and a discharge plate 4 is installed at the bottom of the punch fixed plate 3;

As shown in Fig. 4, Fig. 5 and Fig. 6, the structure of the lower mold assembly is: comprising a lower backing plate 10, on which a punch backing plate 9 is installed through a spring device 8, and the upper part of the punch backing plate 9 is fixed with Die fixed plate 7, die fixed seat 6 is installed on the die fixed plate 7, die 5 is installed by fastener on the die fixed seat 6;

Also comprise the product that needs to process, and product is enclosed within die 5 tops.

As shown in Fig. 7 and Fig. 8, the structure of die 5 is: comprise base 14, be positioned at base 14 top and be provided with connecting plate 13, the length of connecting plate 13 is greater than the length of base 14; The hole 15 has a first through hole 16 between the two first bolt holes 15 . Due to the effect of the connecting plate 13, the die 5 forms a cantilever bridge structure, and the size of the product in the width direction remains unchanged during the processing process, effectively ensuring the processing size of the product and ensuring processing accuracy.

The structure of the die fixing base 6 is: the die fixing base 6 has a cuboid structure, and a groove 17 is opened in the middle, and there are second bolt holes 18 at intervals in the groove 17, which are located between the two second bolt holes 18. A second through hole 19 is opened.

In the actual use process, it is completed through the following steps. As shown in Figure 1, the upper mold assembly and the lower mold assembly are in a separated state. As shown in Figure 2, the processed semi-finished product 11 is transported to the top of the die 5 by a conveyor belt. The semi-finished product 11 is set on the top of the die 5, as shown in Figure 3, the upper mold assembly is pressed down by the action of the press, and the downward extrusion force of the punch 2 is squeezed on the left and right sides of the semi-finished product 11 to realize the semi-finished product 11 Bending at both ends, after bending, the semi-finished product 11 continues to advance and discharge on the connecting plate 13 of the die 5, and finally as shown in Figure 9, the finished product 12 is processed.

The structure of the utility model is mainly used in molds required by high-precision products, and the direction perpendicular to the bending direction can be selected as the feeding direction of the product according to the characteristics of the product. The pre-bending and forming of the product are completed on the same die, because the direction of the die is the same as that of the product. Therefore, the concave mold does not need to come out of the product, and at the same time, due to the existence of the concave mold, the bending size of the inner cavity of the product can be well guaranteed.

The above description is an explanation of the utility model, not a limitation of the utility model. For the scope limited by the utility model, please refer to the claims. Within the protection scope of the utility model, any form of modification can be made. the
