[0027] Two groups of lower die seats 13 are arranged on the processing table 1, and the two groups of lower die seats 13 are respectively arranged at the two ends of the feeding mechanism 3, and guide rollers 17 are arranged between the two groups of lower die seats 13 and the feeding mechanism 3, and concave dies 14 are arranged in the two groups of lower die seats 13, and the two groups of concave dies 14 are respectively arranged directly below the corresponding group of convex dies 1209, and the bottom end of the top plate 6 is rotatably connected with a material changing mechanism 16; Specifically, a group of plates to be processed are pushed onto a group of dies 14 through the material changing mechanism 16, and are stamped and formed by moving the punch 1209 downward. At this time, another group of punches 1209 are moved upward for demolding, and another group of plates to be processed are pushed onto the dies 14 corresponding to the group of punches 1209 through the material changing mechanism 16. At the same time, the stamped plates are pushed to a corresponding group of unloading mechanisms 4 for transportation.

[0028] The material changing mechanism 16 includes a rotating shaft 1601; illustratively, as Figure 5 shown.

[0029] The top end of the rotating shaft 1601 passes through the top plate 6 and is fixedly connected to the center of the worm gear 8.

A telescopic cylinder 1604 is installed on the linkage plate 1603. The output end of the telescopic cylinder 1604 passes through the linkage plate 1603 and is transmission-connected to a push plate 1605. Specifically, the worm gear 8 drives the rotating shaft 1601 to rotate, so that the linkage plate 1603 drives the push plate 1605 to rotate to one side of the feeding mechanism 3. At this time, the worm gear 8 rotates to make one group of punches 1209 move downward for stamping operation, and the other group of punches 1209 move upward for demolding operation. At this time, the opening direction of the push plate 1605 is toward the corresponding die 14 of the demolding operation.

At the same time, the sheet to be processed pushes the finished sheet demolded from the die 14 to the corresponding group of unloading mechanism 4 for transportation. While the two groups of punches 1209 perform stamping operations alternately, the position of the push plate 1605 is switched synchronously, so that the sheet on one group of die 14 completes the stamping operation while the other group of die 14 changes the sheet, thereby effectively improving the processing efficiency of sheet stamping.

[0030] For example, Figure 6-8 shown.

[0031] A groove 1301 is provided in the lower die base 13, the inner wall of the groove 1301 is movably fitted with the concave die 14, an auxiliary demoulding mechanism 15 is provided in the groove 1301, a plurality of groups of telescopic rods 18 are provided at the bottom end of the concave die 14, a plurality of groups of springs 19 are provided between the concave die 14 and the bottom end of the inner wall of the groove 1301, and the plurality of groups of springs 19 are respectively sleeved on the plurality of groups of telescopic rods 18; The auxiliary demoulding mechanism 15 includes an upper sealing ring 1501 and a lower sealing ring 1502, wherein the upper sealing ring 1501 is fixedly connected to the bottom end of the concave mold 14, and the lower sealing ring 1502 is fixedly connected to the bottom end of the inner wall of the groove 1301, and a telescopic air pipe 1503 is arranged between the upper sealing ring 1501 and the lower sealing ring 1502, and several groups of telescopic rods 18 are arranged inside the telescopic air pipe 1503, and two groups of bent pipes 1504 are arranged on the side wall of the lower sealing ring 1502, and the two groups of bent pipes 1504 are interconnected with the inside of the telescopic air pipe 1503, and the two groups of bent pipes 1504 are connected with a transverse pipe 1505, and the two groups of bent pipes 1504 and the transverse pipe 1505 are embedded in the lower mold base 13, and the two groups of transverse pipes 1505 are connected with several groups of air guide pipes 1506, and one end of the several groups of air guide pipes 1506 extends into the groove 1301; Specifically, the sheet to be processed is pushed onto the die 14, and the punch 1209 is moved downward so that the punch 1209 contacts the sheet to be processed and extrude it. The punch 1209 drives the die 14 to move downward, so that the telescopic rod 18 contracts, the spring 19 is gradually compressed, and the telescopic air pipe 1503 is compressed at the same time. After the stamping operation is completed, the punch 1209 moves upward. Due to the tension of the spring 19, the die 14 moves upward, driving the telescopic air pipe 1503 to stretch. While the telescopic air pipe 1503 is stretched, negative pressure is generated at the air inlet ends of several groups of air guide pipes 1506, which generates a suction force on the finished sheet, so that the finished sheet is separated from the punch 1209. At the same time, the die 14 moves upward to push the finished sheet out, so that the push plate 1605 can be convenient for material changing operation.

[0032] The working principle of the building board stamping forming equipment proposed by the present invention is as follows: The servo motor 10 drives the worm 11 to perform intermittent forward and reverse rotation, so that the worm wheel 8 performs synchronous forward and reverse motion, thereby causing the two sets of tooth plates 9 to perform intermittent reciprocating translational motion in opposite directions synchronously. By making the two sets of sliding bolts 901 movably fit with the two sets of sliding grooves 601 respectively, the two sets of tooth plates 9 are effectively prevented from being offset during the reciprocating motion, thereby improving the stability of the movement of the two sets of tooth plates 9.

[0033] By making the two groups of tooth plates 9 perform intermittent reciprocating translational motion in opposite directions synchronously, the two groups of gears 1201 perform intermittent forward and reverse motion respectively, and through the transmission relationship between the active pulley 1202 and the driven pulley 1204, the gear 1201 and the transmission wheel 1203 respectively drive the two groups of screw rods 1206 to perform intermittent forward and reverse motion in the same direction, so that the upper mold base 1208 drives the punch 1209 to perform intermittent up and down reciprocating motion, and when one group of punches 1209 moves downward for stamping operation, the other group of punches 1209 moves upward for demolding operation.

[0034] The worm gear 8 drives the rotating shaft 1601 to rotate, so that the linkage plate 1603 drives the push plate 1605 to rotate to one side of the feeding mechanism 3. At this time, the worm gear 8 rotates to make one group of punches 1209 move downward for stamping operation, and the other group of punches 1209 move upward for demolding operation. At this time, the opening direction of the push plate 1605 is toward the corresponding die 14 of the demolding operation. The push plate 1605 is driven by the telescopic cylinder 1604 to move toward the demolding die 14, and the sheet to be processed on the feeding mechanism 3 is pushed onto the group of die 14. At the same time, the sheet to be processed pushes the finished sheet demolded from the die 14 to the corresponding group of unloading mechanisms 4 for transportation. While the two groups of punches 1209 perform stamping operations alternately, the position of the push plate 1605 is switched synchronously, so that the sheet on one group of die 14 completes the stamping operation while the other group of die 14 changes the sheet, thereby effectively improving the processing efficiency of sheet stamping.

[0035] The sheet to be processed is pushed onto the die 14, and the punch 1209 is moved downward so that the punch 1209 contacts the sheet to be processed and extrude it. The punch 1209 drives the die 14 to move downward, so that the telescopic rod 18 contracts, the spring 19 is gradually compressed, and the telescopic air pipe 1503 is compressed at the same time. After the stamping operation is completed, the punch 1209 moves upward. Due to the tension of the spring 19, the die 14 moves upward, driving the telescopic air pipe 1503 to stretch. While the telescopic air pipe 1503 is stretched, negative pressure is generated at the air inlet ends of several groups of air guide pipes 1506, which generates a suction force on the finished sheet, so that the finished sheet is separated from the punch 1209. At the same time, the die 14 moves upward to push the finished sheet out, so that the push plate 1605 can be convenient for material changing operation.

[0036] Based on the above-mentioned building board stamping and forming equipment, the embodiment of the present invention further proposes a method for the forming equipment. Exemplarily, the method includes: In the initial state, the push plate stays on one side of the feeding mechanism, the telescopic cylinder is turned on, and the push plate pushes a group of plates to be processed to a group of concave dies and then resets; Turn on the servo motor, and the worm gear drives the two sets of gear plates to move in opposite directions; One set of punches moves upwards, and the other set of punches moves downwards to punch the sheet to be processed; At this time, the worm gear drives the material changing mechanism to rotate, so that the push plate rotates to the other side of the feeding mechanism, and the telescopic cylinder is turned on. The push plate pushes a group of plates to be processed to the concave die corresponding to the upward moving punch and then resets; After the punch completes the stamping, the servo motor is controlled to rotate in the opposite direction, so that the worm gear drives the two sets of tooth plates to move in opposite directions; At this time, the punch that has completed the stamping moves upward, the corresponding die of this set of punches is reset, the finished plate stays on the surface of the lower die seat, the material changing mechanism performs the material changing operation, and at the same time, the other set of punches moves downward to perform the stamping operation; The two sets of punches perform alternate stamping and demoulding operations in a cycle, and the material changing mechanism performs cyclic reciprocating rotation and material pushing operations.
