Detailed Description

Other advantages and advantages of the present utility model will become apparent to those skilled in the art from the following detailed description, which, by way of illustration, is to be read in connection with certain specific embodiments, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The stamping and shaping die disclosed by the utility model is mainly used for producing automobile sheet metal parts and requires a workpiece to be molded once, and for this purpose, please refer to fig. 1-8 together, a specific design structure of the die is now described, and the stamping and shaping die mainly comprises an upper die holder 1, a lower die holder 3, a female die 5, a male die assembly 6 and an inner guide member 7. The upper die holder 1 is aligned with the lower die holder 3, an outer guide member 2 is vertically arranged at the bottom of the upper die holder 1, the upper end of the outer guide member 2 is fixedly connected with the outer side of the upper die holder 1 in a threaded manner, the bottom of the outer guide member 2 is slidably inserted into a groove at the outer edge of the lower die holder 3, so that the lower die holder 3 can slide along the length direction of the outer guide member 2, and further, in the embodiment, an elastic part 9 is arranged at the top of the lower die holder 3, the elastic part 9 is a strong spring and is used for supporting the upper die holder 1 to enable the die to open in a natural state, meanwhile, a floating member 4 is also arranged in the lower die holder 3, and after blank stamping forming, products need to be supported by the floating member 4 so that a material belt can be fed continuously.

Specifically, as shown in fig. 4, the float 4 passes through the female die 5 to support the male die assembly 6, when a blank is entered, the blank is inserted between the male die assembly 6 and the female die 5, is extruded with the female die 5 through the male die assembly 6, is embedded into the female die 5, and then after the die is opened, the workpiece is lifted from the female die 5 by the float 4 so that the tape or blank continues to enter the die. In addition, a sensor is mounted on the float 4, and when the float 4 moves, the sensor is triggered, so that the produced product is counted.

In this embodiment, as shown in fig. 4 and 6, the top of the punch assembly 6 is connected to the upper die holder 1 through a plurality of dampers 8 arranged in parallel, and the length of the damper 8 subjected to pressure is shortened, so that when the die is closed, the concentrated stress generated when the forming insert punches the workpiece is borne. On this basis, the male die assembly 6 includes a shaping press block 61 and a bending press block 62, wherein the top of the shaping press block 61 is connected with the damper 8, the top of the bending press block 62 is screwed and fixed at the bottom of the upper die holder 1, and the middle part of the bending press block 62 is slidably provided with the shaping press block 61, and in this embodiment, the thickness of the shaping press block 61 is greater than that of the bending press block 62. Therefore, when the upper die holder 1 is pressed down, the shaping press block 61 will first extrude the middle part of the blank, so that the middle part of the blank is first shaped, then, in the process that the upper die holder 1 continues to be pressed down, the bending press block 62 continuously moves and presses the two sides of the blank, so as to press the blank against the female die 5, so that the two sides of the blank are bent, and finally shaped. During this process, since the lower die holder 3 is vertically fixed with the inner guide 7, both the die 5 and the bending press 62 are adapted to slide along the inner guide 7, thereby maintaining the die 5 in alignment with the entire punch assembly 6 to avoid die damage.

In this embodiment, as shown in fig. 8, a punch 63 is movably inserted into the shaping press block 61, the end of the punch 63 is fixedly mounted at the bottom of the upper die holder 1, and when the die is closed, the punch 63 moves downward in synchronization with the bending press block 62, and the workpiece is punched while the blank is bent.

In this embodiment, as shown in fig. 3, the bending press block 62 is formed by splicing a plurality of inserts, and the inserts are mutually adjacent to form a complete curved surface, so that when one insert is damaged, the insert can be replaced timely and conveniently.

In some embodiments, as shown in fig. 7, the float 4 includes an insert 41, a spring rod 42 and a limit post 43, and the top surface of the insert 41 is flush with the die 5 to form a molded shape of the product. While the bottom of the insert 41 is connected with a spring rod 42, and the top is provided with a limit post 43 for supporting the upper die holder 1 and preventing the male die assembly 6 from deforming due to excessive die closure.

In some embodiments, as shown in fig. 6, a blanking channel 10 is disposed in the lower die holder 3, and the blanking channel 10 is communicated with the female die 5, so that the leftover materials generated by punching of the punch 63 can be discharged, and the leftover materials are prevented from being retained in the die, so that the problem of accumulation is caused.

In some embodiments, as shown in fig. 5, the outer sides of the upper die holder 1 and the lower die holder 3 are provided with a plurality of handles 01, so that the dies can be conveniently carried manually, and in addition, the handles 01 can be bound on the crown block to move, so that the dies can be conveniently transported or moved.

While the utility model has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the utility model and are intended to be within the scope of the utility model as claimed.
