[0022] See also Figure 1-Figure 4 A composite blanking die with easy installation includes: a top plate 100, a die 150, a limit frame 170 and a blanking trough 240, and a group of punch heads 120 for connecting with external punching equipment are arranged at the middle position of the upper end of the top plate 100;

[0023] A group of embedding grooves 110 for mutually limiting and embedding with the upper ends of the adjustment columns 130 are provided inside the left and right sides of the top plate 100, and a group of adjustment columns 130 for adjusting the distance between the top plate 100 and the lower mold 180 are provided inside the embedding grooves 110;

[0024] A group of pressure support seats 140 for supporting the upper end of the pressure die 150 is provided in the middle position of the lower end of the top plate 100, a group of pressure dies 150 for stamping the stamping material 210 is provided in the middle position of the pressure support seats 140, and a group of locking dies 160 for covering the upper end of the stamping material 210 is provided at the lower end of the pressure support seats 140. The upper end of the stamping material 210 can be covered by using the locking dies 160.

[0025] A set of limit frames 170 for limiting the front end position of the stamping material 210 is provided at the lower front end of the locking mold 160, and a set of limit frames 200 for limiting the rear end position of the stamping material 210 is provided at the lower rear end of the locking mold 160. The front and rear sides of the stamping material 210 can be limited and pressed by using the limit frames 170 and the limit frames 200.

[0026] A group of lower dies 180 for supporting the bottom of the punching material 210 are disposed at the lower ends of the first limiting frame 170 and the second limiting frame 200 . The lower dies 180 are provided with punching holes 220 for limiting the punching shape.

[0027] A group of blanking troughs 240 for blanking are provided at the lower end of the punching hole 220, and a group of bottom plates 190 for supporting the lower mold 180 are provided at the lower end of the lower mold 180. A group of fixing holes 230 for connecting and fixing with external equipment are provided inside the front and rear sides of the bottom plate 190.

[0028] The upper end of the punch head 120 is connected and fixed to the external stamping equipment. The punch head 120 is a movable mechanism. The punch head 120 and the die 150 are an integrated structure. The die 150 passes through the middle position of the pressure support seat 140 and the locking die 160. The punch head 120 and the die 150 can be used to perform stamping operations on the stamping material 210.

[0029] The specifications of limit frame 1 170 and limit frame 2 200 are the same, and the cross-sections of both are concave structures. A group of guide rollers are provided on the inner sides of the upper ends of limit frame 1 170 and limit frame 200 to facilitate the movement of stamping material 210 back and forth. By using two groups of guide rollers, the stamping material 210 can be moved to facilitate continuous stamping operations.

[0030] See also Figure 1-Figure 4 As the first embodiment of the utility model: In order to solve the problem that the inaccurate position of the material will lead to deviations in the size and shape of the punched parts, these deviations may include the length, width, angle, etc. of the parts not meeting the design requirements, and may even cause defects such as burrs and gaps. First, the staff will pass the punching material to be punched through the limit frame 170 and the limit frame 200. Since the inner side of the upper end of the limit frame 170 and the limit frame 200 is provided with a group of guide rollers for facilitating the forward and backward movement of the stamping material 210, when continuous stamping operation is required, the two groups of guide rollers are used to facilitate the movement of the stamping material 210 for continuous stamping operation. At the same time, the limit frame 170 and the limit frame 200 can effectively limit the moving position of the stamping material 210, thereby ensuring that the stamping material 210 will not be misplaced during the movement.

[0031] See also Figure 1-Figure 4, as the second embodiment of the utility model: based on the description in the above embodiment, further, when the staff uses an external stamping device to apply pressure to the punch head 120, the punch head 120 drives the punch head to punch the punching material 210. After the punch head penetrates the inside of the punching hole 220, the punched mold block enters the inside of the blanking groove 240 through the punching hole 220. Since the inside of the punching hole 220 and the inside of the blanking groove 240 are interconnected, the inner diameter of the cross section of the punching hole 220 is smaller than the inner diameter of the cross section of the blanking groove 240, which can prevent the stamped mold block from scratching the inner side of the lower mold 180 and the inner side of the bottom plate 190 and causing damage to the mold block.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
