A full-automatic sheet press, configured as shown in fig. 5 to 9, including a press main body 7, the press main body 7 being provided with a press die 8; translation mechanisms are arranged on two sides of the stamping die 8, and a pulley type guiding and limiting device is arranged at one end, corresponding to the stamping die 8, of each translation mechanism; one ends of the two translation mechanisms far away from the stamping die 8 are respectively connected with a feeding mechanism and a discharging mechanism, and the translation mechanism connected with the feeding mechanism is provided with a pull-back unit.
The translation mechanism comprises a plurality of support rods 9 arranged in parallel and a feeding clamping jaw capable of moving back and forth along the direction of the support rods 9, and a gap is formed between every two adjacent support rods 9; the feeding clamping jaw comprises a top plate 10 and a bottom plate 11, and a plurality of convex ribs 12 which penetrate through gaps between the supporting rods 9 and are higher than the supporting rods 9 are arranged on the bottom plate 11; one side of the feeding clamping jaw is connected with a sliding block 13, the sliding block 13 is connected with a screw rod 14, and the screw rod 14 is connected with a driving motor 15; the pull-back unit comprises a mounting rack 16 fixedly connected with the sliding block 13, and a pull-back block 17 is connected to the mounting rack 16; a pull-back cylinder 18 for driving the pull-back block 17 to move parallel to the screw rod 14 is connected to the pull-back block 17, and the pull-back block 17 is fixedly connected with the feeding clamping jaw; a positioning pin 19 is arranged on the stamping die 8; the position of the positioning pin 19 corresponds to the position of a die hole on the stamping die 8, the bottom of the positioning pin 19 is connected with a spring 20 positioned in the stamping die 8, and an inclined plane is arranged on the positioning pin 19 towards the feeding direction of the sheet material; a guide rod 21 is arranged on the mounting rack 16, and the pull-back block 17 is connected with the guide rod 21 in a sliding manner; and a limiting top column 22 is arranged on the mounting rack 16, and the limiting top column 22 is positioned on one side of the pull-back direction of the pull-back block 17.
The working principle is as follows: during guiding, the plate 24 is fed between the two pulley frames 1, and the plate 24 is guided by utilizing the structure that the distance between the two pulley frames 1 is gradually reduced along the feeding direction; during guiding, the pulleys 2 on the pulley frame 1 are used for rolling and guiding the plate 24, so that the guiding effect is improved; when the pulleys 2 are guided in the horizontal direction, the guide and the limit of the plate 24 in the vertical direction can be performed by utilizing the structure that the widths of the pulley grooves of the pulleys 2 are gradually reduced along the feeding direction, so that the end part of the plate 24 is prevented from being upwarped; when the punching process is used for processing plates 24 (different in width) of different specifications, the distance between the two pulley frames 1 can be adjusted through the adjusting cylinder 3, and then the shortest distance between the two pulley frames 1 (the shortest pulley groove distance between the pulleys 2 on the two pulley frames 1) is equal to the width of the plate 24, so that the plates 24 of different widths can be guided and positioned.
When the full-automatic sheet punching machine works, the feeding mechanism moves the sheet material 24 to the translation mechanism, and then the feeding clamping jaw presses the sheet material 24; at this time, the convex rib 12 on the bottom plate 11 is higher than the support rod 9, so the top plate 10 and the convex rib 12 on the bottom plate 11 clamp the plate 24 tightly; then, the driving motor 15 is started to drive the screw rod 14 to rotate, so that the screw rod slider principle is utilized to drive the slider 13 to move horizontally, and the feeding clamping jaw is driven to clamp the plate 24 to move horizontally, so that horizontal feeding is realized; when the feeding clamping jaw moves horizontally, the gap between the supporting rods 9 provides a clamping space and a moving space for the convex ribs 12, so that the feeding of the clamping plates 24 is facilitated while the bottom support is realized for the plates 24 with different specifications. In a similar way, after the punching machine performs punching on the plate 24, namely, after a sheet (key blank) is processed, the translation mechanism of the punching machine corresponding to the direction of the blanking mechanism is started (namely, when in use, two translation mechanisms are required to be respectively arranged on two sides of the punching machine for feeding translation and discharging translation). The working principle of the translation mechanism is the same as that of the prior art, and the material pushing is only carried out from the tail part of the original clamping plate 24, and the material pulling is carried out from the head part of the clamping plate 24.
The working principle of the pull-back unit is as follows, when the sheet punching machine performs primary punching, the situation of vibration and deviation of the sheet material 24 is easy to occur due to the clamping stability of the feeding clamping jaw and the problem of punching vibration; therefore, when the next feeding is carried out, the distance for feeding the plate 24 into the punching machine by the feeding clamping jaw is larger than the standard distance between two adjacent punching; at this time, under the pushing of the plate 24, the inclined surface of the positioning pin 19 is stressed to make the positioning pin 19 retract into the stamping die 8 downwards, so that the plate 24 can be normally fed and advance, and when a through hole (the position of which corresponds to a die hole of the stamping die 8) formed after the plate 24 is stamped is located at the position of the positioning pin 19, the positioning pin 19 automatically extends out of the stamping die 8 under the restoring force of the spring 20 (namely, the positioning pin 19 is inserted into the through hole formed after the plate 24 is stamped); then starting a pull-back unit, and pushing a pull-back block 17 to pull back and move (the moving direction is opposite to the feeding direction) along a guide rod 21 by a pull-back cylinder 18 to drive a feeding clamping jaw and a plate 24 to pull back; the pull-back distance can be controlled by setting the maximum pull-back force of the pull-back cylinder 18, namely after the positioning pin 19 positions the plate 24, the maximum pull-back force of the pull-back cylinder 18 can not pull the plate 24 or the feeding clamping jaw any more; drawing back and positioning, and then carrying out next stamping processing; therefore, automatic pull-back positioning operation is realized, and the use is convenient.
