Referring to fig. 1 to 8, the present invention provides a forming mold for an upper cross member of a seat.
A seat upper beam forming die comprises an upper die 2, a lower die 1 and a carrying device, wherein the lower die is provided with a feeding station 90, a stretching station 91, a first punching and trimming station 92, a second punching and trimming station 93, a first shaping station 94, a side punching and side trimming station 95, a side hole turning station 96, a hole turning station 97, a puncturing station 98 and a second shaping station 99; the carrying device comprises two horizontally arranged support rods 31 and a driving device (not shown in the figure) for driving the two support rods to move up and down and horizontally, and each support rod is provided with a material clamping finger 32 corresponding to each station. Each of the "stations" referred to herein is the loading station, the stretching station, the first punching and trimming station, the second punching and trimming station, the first shaping station, the side punching and side trimming station, the side hole turning station, the hole flanging station, the piercing station, and the second shaping station as previously described. The seat upper cross beam belongs to a special-shaped piece, the specific shape of a forming punch arranged at each station corresponding to the upper die is not limited, the number of punched holes on the seat upper cross beam is determined by actual production, and the number of punches is not limited. The driving device has various implementation manners, and is not limited herein, so as to be capable of driving the two support rods to move up and down and horizontally.
It can also be observed from fig. 3 that the lower die is provided with two "idle" stations 900, i.e. without any machining. This is due to the mold configuration, leaving an idle station for other stations to be configured. The "no walk" station is outside the scope of the present invention.

As shown in fig. 5 and 7, further, the lower die is provided with two first sliding blocks 51 corresponding to the side punching and side trimming stations, each first sliding block is provided with a punch for side punching and a cutter (not visible in the view of the drawing) for side trimming, and the outer side of each first sliding block is provided with an inclined surface 510; the bottom of the upper die is provided with a first push block 52 corresponding to each first slide block, the inner side of each first push block is provided with an inclined plane 520, and the inclined plane of the inner side of each first push block is equal to the inclined plane of the outer side of the corresponding first slide block in inclination angle. Namely, after the upper die is pressed downwards, the inclined surface of each first push block presses the inclined surface of the corresponding first slide block and generates horizontal separation, so that the first slide blocks horizontally move to realize side punching and trimming.
Furthermore, each first sliding block is connected with the lower die through a linear guide rail (not visible in the view angle of the attached drawing), and the first sliding blocks are guided by arranging the linear slide rails.
Furthermore, a second slide block 61 is arranged on the lower die corresponding to the side hole flanging station, hole flanging punches (not visible in the view of the drawing) for side hole flanging are respectively arranged on the second slide block, and an inclined surface 610 is respectively arranged on the outer side of the second slide block; the bottom of the upper die is provided with a second push block 62 corresponding to the second slide block, the inner sides of the second push blocks are respectively provided with an inclined plane 620, and the inclined plane of the inner side of the second push block is equal to the inclined plane of the outer side of the second slide block in inclination angle. During actual processing, when the upper die is pressed downwards, the inclined surface of the second push block presses the inclined surface of the corresponding second slide block and generates horizontal separation, so that the second slide block moves horizontally to realize side punching and trimming.
As shown in fig. 2 and 3, a plurality of guide holes 80 are formed in the top of the lower mold, and a guide post 81 is formed in the bottom of the upper mold corresponding to each guide hole. When the upper die is pressed downwards, each guide post is respectively inserted into the corresponding guide hole, so that the guide effect is achieved.
During the in-service use, above-mentioned seat entablature forming die sets up on the punching machine, and seat entablature forming die shaping mainly includes following step:
(1) feeding the upper seat beam from a feeding station; the upper seat cross beam is an unformed plate;
(2) the carrying device carries the seat upper cross beam to a stretching station; pressing the upper die downwards, and stretching and forming the upper cross beam of the seat;
(3) the carrying device carries the seat upper cross beam to a first punching and trimming station; pressing an upper die downwards, and punching and trimming an upper cross beam of the seat for the first time;
(4) the carrying device carries the seat upper cross beam to a second punching and trimming station; pressing the upper die downwards, and performing secondary punching and trimming on the upper cross beam of the seat;
(5) the carrying device carries the seat upper cross beam to a first shaping station; pressing the upper die downwards, and shaping the upper cross beam of the seat for the first time;
(6) the carrying device carries the seat upper cross beam to a side punching and side trimming station; pressing an upper die downwards, and performing side punching and side trimming on the seat upper cross beam;
(7) the carrying device carries the seat upper cross beam to a first side hole turning station; pressing the upper die downwards to perform side hole flanging on the upper cross beam of the seat;
(8) the carrying device carries the seat upper cross beam to a hole flanging station; pressing the upper die downwards to perform hole flanging on the upper cross beam of the seat;
(9) the carrying device carries the seat upper cross beam to a puncture station; pressing the upper die downwards to puncture the upper cross beam of the seat;
(10) the carrying device carries the seat upper cross beam to a second shaping station; and pressing the upper die downwards to perform secondary shaping on the upper cross beam of the seat.
In actual operation, the upper die is pressed down each time, and the upper seat cross beam on each station is processed. The two support rods are respectively positioned on two sides of the upper part of the lower die, the clamping jaws clamp the corresponding upper seat beam to improve stability during machining, the driving device of the carrying device drives the two support rods to move up, translate and move down, and meanwhile, after the seat beam on each station is carried to the next station, the carrying device drives the two support rods and the clamping jaws to reset, so that the reciprocating motion is realized, and the continuous machining of the upper seat beam is realized.
