detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in the accompanying drawings 2-5, a blanking die for the reinforced plate of the automobile chassis assembly described in the utility model includes an upper mold assembly and a lower mold assembly that move up and down relative to each other through several independent guide pillars 19, and Material screw 1 and stripping plate guide post 2; the upper mold assembly includes an upper template 3, an upper backing plate 4, an upper fixing plate 5, a stripping plate 6 and an upper backing plate 4 that are connected in sequence from top to bottom The punch 7 on the top; a plurality of springs 8 are also provided between the discharge plate 6 and the upper fixing plate 5; four punches 7 are arranged at the lower end of the upper backing plate 4; Two ejector pins 9 are also provided; the punches 7 are arranged in two rows, and the front and rear positions of the two rows of punches 7 are opposite; the two rows of punches 7 are symmetrical about the die center line 20; the arbitrary The vertical height of a row of punches 7 is higher than the height of one punch 7 in another row; the lower mold assembly includes a lower template 10, a die foot 11, a press plate 12, a lower backing plate 13 and is fixed on the lower backing plate 13. The die 14; the structure of the die 14 is compatible with the punch 7; the lower template 10 is connected to the press plate 12 through a plurality of die feet 11; the upper template 3, the upper backing plate 4, the upper The fixed plate 5 and the unloading plate 6 are connected by unloading screws 1; the lower end of the upper backing plate 4 is provided with an unloading plate guide post 2; the unloading plate guide post 2 passes through the upper fixing plate 5 and the unloading plate. plate 6, and the die 14 is provided with corresponding guide post grooves; the side of the upper fixed plate 5 is also provided with a scrap knife 15; one side of the die foot 11 is provided with a slide plate 16; one end of the slide plate 16 It is connected with the lower backing plate 13, and the other end is connected with the waste box 17; the number of the mold feet 11 is three; several limit posts 19 are also arranged between the upper mold assembly and the lower mold assembly.

As shown in the accompanying drawings 2-5, a blanking die for a reinforcement plate of an automobile chassis assembly described in the utility model, before the actual processing, the upper template is connected with the stamping mechanism, and when starting to process the blank, the feeding mechanism will roll the material Send it to the concave film of the blanking die, and then the stamping mechanism starts to work. When the stamping mechanism punches down, it drives the upper template, the upper fixing plate, the upper backing plate and the unloading plate to fit each other and press down, driving the upper pad The punch at the lower end of the plate and the die at the top of the lower backing plate are pressed against each other, so that the four punches at the lower end of the upper backing plate are aligned with the coil material for punching, so that the coil material passes through the four holes on the lower backing plate. One concave film can process four blanks at one time; and because the four convex parts in the punch are arranged in two rows, and there is a gap between each other, this can ensure that each part is under pressure when the coil is stamped. Balanced, to avoid the problem of inconsistency in the size of the four processed blanks, and to improve the accuracy of the processed blanks. Then the feeding mechanism continues to convey the coil material, and then the blanking die can be processed in a circular manner.

When the blanking die is processed, the stamping mechanism stops working, and then the unloading screw is loosened, and then the unloading plate automatically returns to the initial position through the spring, so that the blanking die returns to the normal state.

Further, a waste knife is provided on the side of the upper fixing plate, which is used to cut off the remaining waste on the roll material. A slide plate is also provided on one side of the upper formwork, and the other end of the slide plate is connected with the waste box. After cutting off the waste with the waste knife, The waste can be automatically entered into the waste box through the slide plate; there is also a limit column between the upper mold assembly and the lower mold assembly to prevent the positions of the upper mold assembly and the lower mold assembly from being misplaced during use direction.

For the blanking die of the reinforced plate of the automobile chassis assembly mentioned above, four blanks can be stamped out by one stamping of the stamping mechanism, the production efficiency is increased by four times, and the utilization rate of raw materials is greatly improved. It depends on different products. Raw material utilization can generally be increased by 16% to 30%.

A blanking die for the reinforced plate of the automobile chassis assembly according to the utility model has the advantages of convenient operation and labor-saving, simple and practical structure, high efficiency and fast punching out of blanks, and can process four blanks at one time, and can also pass through After the scrap knife cuts the scrap, it automatically slides into the scrap box through the slide plate, which not only improves the production efficiency and saves the production cost, but also greatly improves the utilization rate of raw materials, prolongs the service life of the blanking die, and makes the scrap properly collected. It can be widely used in various stamping industries and has high promotion and practical value.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. All technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the utility model.
