Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, and in particular to a stamping equipment capable of quickly replacing dies. Background Art

[0002] In modern industrial production, stamping is a widely used forming process for manufacturing various metal and non-metal parts. With the increasingly fierce market competition and the accelerated speed of product replacement, higher requirements are placed on the performance and efficiency of stamping equipment. Traditional stamping equipment has many problems in mold replacement. On the one hand, the installation and removal process of the mold is cumbersome and complicated. Usually a large number of tools are required to perform multiple tightening and loosening operations of bolts and nuts, which consumes a lot of manpower and time. For example, in some traditional stamping equipment, the mold is fastened to the equipment working platform through multiple evenly distributed bolts. When replacing the mold, workers need to unscrew these bolts one by one, and then align the new mold and tighten it again. The whole process may take several hours or even longer, which seriously affects production efficiency. On the other hand, traditional stamping equipment is not accurate and reliable in mold positioning and locking. The position deviation after the mold is installed is difficult to effectively control, which easily leads to unstable dimensional accuracy and quality of the stamped product. At the same time, during the stamping process, since the mold is subjected to a large impact force, if the locking device is unreliable, the mold may be displaced or loosened, which not only affects the product quality, but also may cause safety accidents. In addition, with the continuous improvement of the degree of automation in industrial production, enterprises are in urgent need of stamping equipment that can quickly change molds to achieve rapid switching production of different products, improve equipment utilization, and reduce production costs. However, existing stamping equipment is difficult to meet this demand, becoming a bottleneck restricting the improvement of enterprise production efficiency and competitiveness.

[0028] Among them, the connecting seat 92 is T-shaped; the guide groove three 918 is a T-shaped guide groove; the motor 2 is a reduction motor with a brake; and the stamping device 10 is a stamping cylinder.

[0029] The use state of the present invention is as follows: the present invention has a reasonable and simple structure, low production cost, and convenient installation. When in use, first, the motor 2 (reduction motor with brake) is located inside the lower left side of the base 1 and is in a stationary and unstarted state. The limit block 3 is fixed to the lower left side of the guide groove 4. The guide groove 4 is transversely opened on the top surface of the lower right side of the base 1. The screw 5 is movably connected to the center of the guide groove 4, and its left center is fixedly connected to the right output shaft of the motor 2, but the screw 5 does not rotate at this time. The movable seat 6 is connected to the screw 5 through the central threaded hole. The outer side of the movable seat 6 is transversely movably connected to the inside of the guide groove 4 and is in the initial position. The positioning locking device 7 is fixed to the top center of the movable seat 6, and the lower side of the mold 8 is fixed to the upper side of the positioning locking device 7. The die 8 is fixedly connected. At this time, the die 8 is in a state of waiting for stamping. The upper side of the stamping device 10 (stamping cylinder) is located inside the upper right side of the machine base 1. The adaptive locking device 9 is fixed to the bottom of the stamping device 10, connected to the upper side of the die 8 and in a locked state, so that the die 8 remains stable during the stamping process. During stamping, the stamping device 10 is started to move downward, driving the adaptive locking device 9 and the die 8 to close the mold, and the workpiece is stamped. When disassembling the die 8, first use an inner hexagonal wrench to insert the inner hexagonal holes of the outer side of the jacking screw 94 and the locking screw 97 respectively, and slowly rotate the jacking screw 94 counterclockwise to gradually withdraw it from the threaded holes on both sides of the connecting groove 93, thereby releasing the jacking effect on the connecting seat 92;At the same time, rotate the locking screw 97 counterclockwise to make the clamping block 2 913 gradually move outward and away from the upper side of the mold 8 under the action of spring 2 911 and spring 2 915. Then start the rising control button of the punching device 10, and the cylinder piston rod of the punching device 10 begins to retract upward, driving the adaptive locking device 9 to move upward and away from the mold 8 as a whole. Press the starting button of the motor 2, and the motor 2 is powered on and starts to run. The right output shaft drives the screw 15 to rotate clockwise. Since the threaded hole in the center of the movable seat 6 is connected to the screw 15, under the action of the threaded transmission, the movable seat 6 slowly moves to the right along the guide groove 14, and the mold 8 is gradually moved out of the inside of the machine base 1. After the mold 8 is completely moved out, stop the motor 2 and use the hexagon socket The wrench is inserted into the hexagonal hole of the locking head 76 on the outer side of the double-headed screw rod 72, and the double-headed screw rod 72 is driven to rotate counterclockwise. Since the external threads on both sides of the double-headed screw rod 72 rotate in opposite directions, as the double-headed screw rod 72 rotates, the movable block 74 gradually moves outward in the guide groove 2 73, and the connecting guide block 1 79 and the clamping block 1 710 also move outward under the action of the spring 1 78, so that the clamping block 1 710 is away from the lower side of the mold 8. At this time, the mold 8 to be disassembled can be removed from the support seat 71. When installing the mold, the mold 8 to be installed is placed steadily on the support seat 71 to ensure that the position of the mold 8 is roughly in the center of the support seat 71. Use an inner hexagonal wrench to insert the inner hexagonal hole of the locking head 76 on the outer side of the double-headed screw rod 72 and rotate clockwise. Turn the double-headed screw 72. As the double-headed screw 72 rotates, the movable block 74 gradually moves inward in the guide groove 2 73, and pushes the clamping block 1 710 to move inward through the connecting guide block 1 79 until the clamping layer 712 of the clamping block 1 710 clamps the lower side of the mold 8 in the center, and the pressing layer 711 presses the mold 8 to preliminarily fix the mold 8 on the support seat 71. Start the descending control button of the stamping device 10, and the cylinder piston rod of the stamping device 10 begins to extend downward, driving the adaptive locking device 9 to move downward as a whole and approach the mold 8. When the adaptive locking device 9 approaches the mold 8, stop the descent of the stamping device 10, use an inner hexagonal wrench to insert the inner hexagonal hole on the outside of the locking screw 97, and rotate the locking screw 97 clockwise. The external threads of the two locking screws 97 are rotated in opposite directions. During the rotation process, the movable guide block 98 moves toward each other in the guide groove 3 918, and pushes the clamping block 2 913 to move inward through the connecting guide block 2 912 until the clamping block 2 913 is aligned with the upper side of the clamping mold 8. During the clamping process, the connecting seat 92 (in a T shape) can move adaptively in the connecting groove 93 to adapt to the position deviation of the mold 8 to avoid subsequent adjustments. Finally, use an inner hexagonal wrench to insert the inner hexagonal hole on the outside of the tightening screw 94, and rotate the tightening screw 94 clockwise to gradually screw it into the threaded holes on both sides of the connecting groove 93, tighten the connecting seat 92 to fix it, and complete the fixation of the mold 8. At this time, the equipment returns to the state of waiting for stamping, and the next stamping operation can be carried out. ;
