Before the mold 4 is pushed out of the limit component 107, the ejecting cylinder 105 inside the moving seat 103 is started, so that the ejector rod descends, and then the stop head 5 falls back into the limit component 107. Subsequently, the anti-leakage cylinder 812 is started, and the ejector pins 809 will move downward, so as to push the stop head 5 stuck on the first through hole 101 back into the mold 4, thereby improving the blanking quality of the equipment. When the stop heads 5 all fall back into the limit component 107, the blanking rod 806 pushes the mold 4 out of the limit component 107 and pushes it into the blanking frame 804 through the notch. The moving frame 813 is slidably connected to the blanking frame 804, ensuring the stable movement of the push rod.The blanking rack 804 is provided with a discharge bottom plate that is flush with the bottom of the limit component 107 and the transmission component 104 respectively. The mold 4 pushed out by the ejector rod 806 will move onto the discharge bottom plate. The bottom of the discharge bottom plate is provided with a second ejecting mechanism for ejecting the stop head 5 from the mold 4. The top of the blanking rack 804 is slidably connected with a first blanking component for transferring the stop head 5 to the aggregate frame. The first blanking component is provided with a second blanking component for transferring the mold 4 to the conveying component 9. The conveying component 9 is located between the discharge bottom plate and the aggregate frame. The first blanking component includes a discharge lifting plate 803 slidably connected with the top of the blanking rack 804, a first discharge cylinder 811 fixedly connected to the support base 814 and with its output end connected to the discharge lifting plate 803, a discharge lifting cylinder 801 fixedly connected to the middle of the discharge lifting plate 803, and a transition plate fixedly connected to the output end of the discharge lifting cylinder 80). The transition plate is located below the discharge lifting plate 803. Clamping cylinders 810 are fixedly connected to both sides of the transition plate. The output ends of the clamping cylinders 810 are fixedly connected with a number of first discharge clamping plates 817. The bottom of the first discharge clamping plate 817 is fixedly connected with a second discharge clamping plate 819 for clamping the stop head 5. The bottom of the discharge bottom plate is also provided with a second positioning mechanism for positioning the mold 4. The bottom of the transition plate is also fixedly connected with a limit punching plate 818 for restricting the movement of the mold 4. Two guide plates are also provided on the top of the discharge bottom plate. The mold 4 is located between the two guide plates. The second blanking component includes a number of second discharge cylinders 802 fixedly connected to the top of the blanking rack 804 and a push rod 816 fixedly connected to the output end of the second discharge cylinder 802. The push rod 816 is located between the mold 4 and the pusher frame 807. The push rod 816 is in clearance fit with the sleeve 815. The sleeve 815 is fixedly connected to the top of the blanking rack 804 through a mounting frame. Among them, the second positioning mechanism has the same structure as the first positioning mechanism, and the second ejecting mechanism has the same structure as the first ejecting mechanism;Therefore, when the mold 4 comes out of the notch and moves to the discharge bottom plate, under the action of the guide plate and the positioning rod 215 in the second positioning mechanism, the top of the second positioning mechanism moves. Subsequently, the discharge lifting cylinder 801 and the second discharge cylinder 802 are activated, and the transition plate and the push rod 816 move downward, so that the limit punching plate 818, the first discharge clamping plate 817 and the second discharge clamping plate 819 move downward. Furthermore, the limit punching plate 818 presses the mold 4. Subsequently, the ejecting cylinder 105 in the second ejecting mechanism is activated, the ejecting rod ejects, and the processed speed limit joint is ejected from the mold 4 by a certain distance. Subsequently, the clamping cylinder 810 is activated, so that the second discharge clamping plate 819 clamps the speed limit joint. Subsequently, the discharge lifting cylinder 801 is activated in the reverse direction, so as to take out the clamped speed limit joint from the mold 4. Subsequently, the positioning rod 215 in the second positioning mechanism moves downward, and then the first discharge cylinder 811 is activated. The discharge lifting plate 803 moves in the direction of the conveying assembly 9. At the same time, the push rod 816 pushes the mold 4 and pushes the mold 4 into the conveying assembly 9. When the mold 4 is pushed into the conveying assembly 9, the first discharge cylinder 811 stops, and the second discharge cylinder 802 is activated in the reverse direction, so as to move the push rod 816 upward. Subsequently, the first discharge cylinder 811 is activated continuously, and the speed limit joint is moved above the aggregate box. Subsequently, the clamping cylinder 810 is activated in the reverse direction, so that the speed limit joint falls into the aggregate box. During this process, the mold 4 will move to the feeding table 3 through the conveying assembly 9, thus realizing a blanking cycle of the speed limit joint.;

[0050] Working principle

[0051] When a speed limit joint needs to be installed, the operator initially installs the copper nail on the knob 5 and then places the knob 5 in the mold 4. Subsequently, under the action of the guide plate and the positioning rod 215 near the feeding table 3, the staff first pushes the mold 4 to the initial position. During the pushing process, the second feeding rocker 205 will rotate. When the mold 4 reaches the positioning rod 215 near the feeding table 3, the second feeding rocker 205 resets under the action of the second spring 202 and is located between the mold 4 and the feeding table 3. After the pressing plate 206 presses the copper nail, the positioning cylinder 213 near the moving seat 103 is activated, and the positioning rod 215 moves downward. Subsequently, the first transfer cylinder is activated, which drives the first moving block 211 to move, and then drives the first feeding rocker 204 to move, thereby pushing the pressed mold 4 to move, and then pushing the pressed mold 4 into the internal part of the limit component 107. Subsequently, the first transfer cylinder resets, and the first feeding rocker 204 resets. Then, the positioning cylinder 213 near the moving seat 103 is activated in the reverse direction, and the positioning rod 215 moves upward;The positioning cylinder 213 near the feeding table 3 is activated, and the positioning rod 215 moves downward. Then, the second transfer cylinder 201 is activated, driving the second feeding rocker 205 to move, thereby driving the next mold 4 to move into the positioning rod 215 near the moving seat 103, and thus completing the automatic feeding of the next mold 4. During the movement of the next mold 4, the ejector cylinder 105 in the first ejecting mechanism is activated, and the ejector rod lifts the stop head 5 and makes the stop head 5 closely adhere to the top of the limiting component 107. At this time, the cylinder on the top of the stop head 5 will pass through the first through hole 101. Subsequently, the transmission component 104 is activated to move the moving seat 103 to the milling frame 602 for milling, and then move to the polishing frame 701 for polishing. Subsequently, the moving seat 103 moves to the alignment position with the blanking frame 804 and the pushing frame 807. Subsequently, the ejector cylinder 105 inside the moving seat 103 is activated, causing the ejector rod to descend, and thus the stop head 5 to fall back into the limiting component 107. Then, the anti-leakage cylinder 812 is activated, and the ejector post 809 will move downward, thereby pushing the stop head 5 stuck on the first through hole 101 back into the mold 4. Subsequently, when the blanking cylinder 808 is activated, the blanking rod 806 will be pushed out, and the mold 4 will be pushed from the limiting component 107 to the blanking bottom plate, and move to the top of the second positioning mechanism under the action of the guide plate and the positioning rod 215 in the second positioning mechanism. Subsequently, the blanking lifting cylinder 801 and the second blanking cylinder 802 are activated, and the transition plate and the push rod 816 move downward, thereby causing the limiting punching plate 818, the first blanking clamping plate 817, and the second blanking clamping plate 819 to move downward, and further causing the limiting punching plate 818 to press the mold 4. Subsequently, the ejector cylinder 105 in the second ejecting mechanism is activated, and the ejector rod ejects, and the processed speed limit joint is ejected from the mold 4 by a certain distance. Subsequently, the clamping cylinder 810 is activated, causing the second blanking clamping plate 819 to clamp the speed limit joint. Subsequently, the blanking lifting cylinder 801 is activated in the reverse direction, thereby taking out the clamped speed limit joint from the mold 4. Subsequently, the positioning rod 215 in the second positioning mechanism moves downward, and then the first blanking cylinder 811 is activated, and the blanking lifting plate 803 will move in the direction of the conveying component 9. At the same time, the push rod 816 pushes the mold 4 and pushes the mold 4 into the conveying component 9. When the mold 4 is pushed into the conveying component 9, the first blanking cylinder 811 stops, and the second blanking cylinder 802 is activated in the reverse direction, thereby moving the push rod 816 upward. Subsequently, the first blanking cylinder 811 is activated continuously, and the speed limit joint is moved above the aggregate frame. Subsequently, the clamping cylinder 810 is activated in the reverse direction, causing the speed limit joint to fall into the aggregate frame. During this process, the mold 4 will move to the feeding table 3 through the conveying component 9, thus realizing an assembly cycle of the speed limit joint. Therefore, the present invention eliminates the problem that workers are required to operate at the extrusion station, milling station, and grinding station, reduces the labor cost, and reduces the labor intensity of workers.
