Detailed Description

The following detailed description of the embodiments of the utility model, given by way of example only, is presented in the accompanying drawings to aid those skilled in the art in a more complete, accurate and thorough understanding of the inventive concepts and aspects of the utility model, and to facilitate their practice.

As shown in fig. 1 to 3, the mold structure of the automobile punching upper tilting wedge comprises an upper mold 1 and a lower mold 2, wherein the upper mold 1 comprises a pressing core 12, the lower mold 2 comprises a male mold 22, an upper tilting cutter block 24 is arranged on the side part of the male mold 22, the upper tilting cutter block 24 is connected with an upper tilting slide block 23, a rigid pressing block 13 is arranged at the bottom of the upper mold 1, a base 26 is arranged on the lower mold 2, a driving block 25 is movably connected on the base 26, one end of the driving block 25 is positioned below the rigid pressing block 13, and the other end of the driving block 25 is positioned below the upper tilting slide block 23.

As shown in fig. 1 to 3, the upper die 1 comprises an upper die body 11, a pressing core 12 and a rigid pressing block 13, the lower die 2 comprises a lower die body 21, a male die 22, an upturning slide block 23, an upturning knife block 24 and a driving block 25, the angular rotation of the driving block 25 can drive the upturning slide wedge mechanism to move, the driving block 25 is perpendicular to the upturning slide block 23, the rigid pressing block 13, the driving block 25 and the upturning slide block 23 are not in the same straight line, the volume of the upturning slide wedge can be reduced, and the situation that the structure is difficult to realize due to space limitation in the upturning slide wedge in the die is avoided.

The working principle of the die structure of the automobile punching upturning wedge is that when an upper die 1 descends, an upper die body 11 drives a pressing core 12 to descend together with a rigid pressing block 13, the pressing core 12 descends until contacting with a male die 22, then the pressing core 12 presses a plate, the rigid pressing block 13 descends gradually to contact with a driving block 25 of a lower die 2, the driving block 25 jacks up an upturning sliding block 23 under the pressure of the rigid pressing block 13 due to the fact that the driving block 25 can rotate, and an upturning cutter block 24 moves along with the upturning sliding block 23 to contact the plate, and upturning is started until the plate is finished when the maximum stroke is reached.

As shown in fig. 2, the base 26 includes a bracket 27, and the middle of the driving block 25 is hinged to the bracket 27. The support 27 is fixedly connected to the upper end of the base 26, the middle part of the driving block 25 is used as a hinge point and a pivot point in the structure, two ends of the driving block are respectively corresponding to the rigid pressing block 13 and the upturning sliding block 23, namely, the force arms of the two ends of the driving block 25 are the same, the pressure transmitted to the driving block 25 by the rigid pressing block 13 can be equal to the pressure transmitted to the upturning sliding block 23 for the plate, meanwhile, the fact that the moving amounts of the rigid pressing block 13 in the descending direction and the moving amount of the upturning sliding block 23 in the ascending direction are the same is ensured, and the design of a die can be facilitated. The upturning slide block 23 moves in the vertical direction, and in the retreating state, the driving block 25 is in a horizontal state, and the angle between the driving block 25 and the upturning slide block 23 is 90 degrees, so that the design scheme that the driving direction and the movement direction of the pulley and the slide block are in the same straight line in the traditional upturning wedge is replaced, and the purpose of reducing the volume of the upturning wedge is achieved.

As shown in fig. 1, a guide slide block 29 is further arranged at the side part of the male die 22, and the guide slide block 29 is matched with the upturning slide block 23. The guide slide block 29 and the upturning slide block 23 are designed to be matched in a sliding rail mode, so that the movement of the upturning slide block 23 in the vertical direction can be guided, the collimation of the movement direction is ensured, and the flanging quality of a product is ensured to be reliable.

As shown in fig. 2, one end of the driving block 25 abuts against the rigid pressing block 13, and the other end abuts against the bottom of the upturned slider 23. The structure is that the driving block 25 is in a working state, after the rigid pressing block 13 presses down one end of the driving block 25, the driving block 25 applies acting force to the bottom of the upturning sliding block 23 through the lever principle, and therefore the upturning process is completed.

As shown in fig. 2, both ends of the driving block 25 are arc-shaped convex structures. The structure makes the end of the driving block 25 smooth, i.e. the contact end of the driving block 25 and the upturning slide block 23 or the rigid pressing block 13 is an arc-shaped bulge part, which can reduce the motion interference influence on adjacent parts during the rotation, ensure the smooth rotation process, and simultaneously reduce the stress concentration generated during the compression of the driving block 25, thereby ensuring the long-term use reliability of the driving block 25.

As shown in fig. 2, the upturned slider 23 has an L-shaped structure. The structure can further reduce the volume of the upturning slide block 23, fully utilize the space below the upturning slide block 23 and improve the compactness of the assembly.

As shown in fig. 3, a cylinder 3 is arranged in the lower die 2, and a piston rod of the cylinder 3 is connected with the bottom of the upturning slide block 23. The cylinder 3 drives the upturning slide block 23 to lift, so that the reset return stroke of the upturning slide block 23 is realized.

As shown in fig. 3, a positioning plate 28 is connected to the upper end of the upturning blade block 24. The positioning plate 28 can perform rough positioning when the plate is placed.

The plate stamping implementation process is that an upper die body 11 descends along with a press to drive a pressing core 12 to descend together with a rigid pressing block 13, after the pressing core 12 descends to contact with a male die 22, the upper die body 11 continues to descend, a nitrogen spring of the pressing core 12 is stressed to compress, the pressing core 12 compresses the plate, an upper die 1 drives the rigid pressing block 13 to continue to descend to contact with a lower driving block 25, the rigid pressing block 13 continues to descend to contact one end of the driving block 25 and rotate the driving block 25, the other end of the driving block 25 pushes up an upturning slide block 23 of the lower die 2 and an upturning knife block 24 of the lower die 2, the upturning knife block 24 starts to contact the plate, the upturning starts until the operation is completed, and the upturning procedure is completed.

The die structure of the automobile stamping upturning wedge solves the problem that the design is difficult due to the fact that the upturning wedge is large in size and limited in die space in the prior art, through the arrangement of the rotatable driving block 25, two ends of the die structure correspond to the rigid pressing block 13 and the upturning sliding block 23 respectively, compared with the prior art, the wedge structure is changed, the upturning space is enlarged, the problem that the upturning space is compact is solved, the downward movement of the rigid pressing block 13 is converted into the upward movement process of the upturning sliding block 23 through the rotation of the driving block 25, the size of the upturning wedge is reduced, the die structure and the production process of products are reduced, accordingly the technological requirements of the same process of upturning are met, the production efficiency is improved, the manufacturing period is shortened, the cost is reduced, and the die structure has wide application prospects in the automobile stamping side-punching process structure.
