Description

Technical Field

[0001] This invention relates to an automatic emptying structure loaded on an electric cylinder pusher for use in the forging field. Background Technology

[0002] The existing pusher feeding mechanism in the induction heating production line has a simple structure and single function. It cannot perform thermal evacuation, resulting in a waste of thermal energy in the forging plant. At the same time, the pusher feeding requires manual assistance, which is cumbersome and affects work efficiency. These problems are particularly prominent when feeding bars weighing more than 15KG. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic emptying structure loaded on an electric cylinder pusher, which can realize automatic feeding and emptying of the material bar.

[0004] One technical solution to achieve the above objective is: an automatic emptying structure loaded on an electric cylinder pusher, including a servo electric cylinder and a billet pusher, and also including an emptying head propulsion cylinder;

[0005] The servo electric cylinder is located at the end of the feeding slide, including an electric cylinder guide rod arranged in the same direction as the feeding slide, and a slide block arranged on the electric cylinder guide rod and slidable along the electric cylinder guide rod. A clearing head pushing cylinder is provided on the slide block. The clearing head pushing cylinder is connected to the billet pusher through a spring mechanism. A proximity switch is provided on one side of the clearing head pushing cylinder, and a triggering mechanism matching the position of the proximity switch is provided on one side of the billet pusher.

[0006] When the clearing head push cylinder retracts, the spring mechanism is in a locked state; when the clearing head push cylinder extends, the spring mechanism is in a free state.

[0007] Furthermore, the billet pusher is connected to the emptying head propulsion cylinder via a pusher guide rod.

[0008] Furthermore, the spring mechanism and the pusher guide rod pass through the second slide block and are respectively connected to the emptying head propulsion cylinder and the billet pusher.

[0009] Furthermore, the electric cylinder pusher has a billet preparation slide and an empty rod storage slide on both sides of the feeding slide, and the billet preparation slide and the empty rod storage slide are respectively connected to the feeding cylinder.

[0010] The automatic feeding method using the above-mentioned automatic emptying structure loaded on the electric cylinder pusher includes a pushing working mode and an emptying working mode;

[0011] When the electric cylinder pusher is in the pushing mode, the feeding slide is full of billet bars. The clearing head pusher cylinder retracts, and the servo electric cylinder drives the slide to perform a periodic reciprocating motion at a fixed distance, thereby driving the billet pusher to push the billet bars to perform repeated feeding operations.

[0012] When the electric cylinder pusher is in the emptying mode, the end of the feeding slide is the emptying rod. The emptying head pusher cylinder extends, and the spring mechanism is in a free state. The servo electric cylinder drives the slide forward, which drives the billet pusher to push the emptying rod, thereby eliminating the gap between the emptying rod and the billet bar. When the gap between the emptying rod and the billet bar, as well as between each billet bar, is completely eliminated, the spring mechanism is compressed and contracts, driving the billet pusher and the trigger mechanism to retract. When the billet pusher is retracted to the correct position, the trigger mechanism triggers the proximity switch to send a sensing signal. At this time, the servo electric cylinder records the position and calculates the movement distance of the emptying mode based on the length of the billet bar and the movement distance of the pushing mode. Then the servo electric cylinder returns to the initial position, the emptying head pusher cylinder retracts, and the cycle reciprocates according to the calculated movement distance of the emptying mode, thereby driving the billet pusher to push the emptying rod to perform repeated emptying and feeding operations.

[0013] This invention discloses an automatic emptying structure and automatic feeding method mounted on an electric cylinder pusher. Based on a conventional pusher device, an automatic emptying device is added, effectively enhancing the functional range of the conventional pusher and automating feeding and emptying. Specifically, the external spring mechanism of the emptying head propulsion cylinder can cooperate with the servo electric pusher cylinder to effectively eliminate the gap between the emptying rod and the last billet. A proximity switch is installed at the spring's working limit position to collect signals, thereby facilitating automated control. The entire device not only meets normal feeding production needs but also adapts to emptying billets of various specifications and lengths during heating, saving energy, achieving greater automation, and reducing labor input. The equipment is easy to adjust and more adaptable to forging production lines with different processes. Attached Figure Description

[0018] Please see Figures 1 to 4 In order to better understand the technical solution of the present invention, the following detailed description is provided through specific embodiments:

[0019] Please see Figure 1 The electric cylinder pusher includes a feeding slide 1, a billet preparation slide 2 storing material bars, and a clearing rod storage slide 3 storing clearing rods 31. The billet preparation slide 2 and the clearing rod storage slide 3 are respectively located on both sides of the feeding slide 1 and connected to the feeding cylinder 4. An automatic clearing structure 5 is provided at the end of the feeding slide 1.

[0020] Please see Figure 2 The automatic emptying structure includes a servo electric cylinder, a billet pusher 6, and an emptying head propulsion cylinder 7. The servo electric cylinder includes an electric cylinder guide rod 51 arranged in the same direction as the feeding slide 1, and a first slide 52 and a second slide 53 mounted on the electric cylinder guide rod 51 and slidable along the guide rod. The emptying head propulsion cylinder 7 is mounted on the first slide 52 and is connected to the billet pusher 6 via a spring mechanism 8. A proximity switch 9 is located on one side of the emptying head propulsion cylinder, and a trigger mechanism 10 matching the position of the proximity switch 9 is located on one side of the billet pusher 6. Simultaneously, the billet pusher 6 is connected to and guided by the pusher guide rod 61. The spring mechanism 8 and the pusher guide rod 61 pass through the second slide 53 and are connected to the emptying head propulsion cylinder 7 and the billet pusher 6, respectively. When the emptying head propulsion cylinder retracts, the spring mechanism is in a locked state; when the emptying head propulsion cylinder extends, the spring mechanism is in a free state.

[0021] The automatic feeding method using the above-mentioned automatic emptying structure loaded on the electric cylinder pusher includes a pushing working mode and an emptying working mode.

[0022] Please see Figure 2 When the electric cylinder pusher is in pushing mode, the feeding slide is filled with billet bars. The clearing head's push cylinder retracts, at which point the spring mechanism is locked. The servo electric cylinder drives the slide block to reciprocate cyclically at a fixed distance, thereby driving the billet pusher to repeatedly push the billet bars for feeding. This distance is adjusted according to the size of different types of billets. After the billet size is input into the industrial control system, the corresponding movement distance will be matched.

[0023] Please see Figure 3When the electric cylinder pusher is in the emptying mode, the end section of the feeding chute, through the emptying rod storage chute's feeding cylinder, sequentially flips the emptying rod into the feeding chute according to the controlled preset rhythm. At this time, the emptying head pusher cylinder extends, the spring mechanism is in a free state, and the servo electric cylinder drives the slide forward, driving the billet pusher to push the emptying rod, thereby eliminating the gap between the emptying rod and the billet bar. When the gaps between the emptying rod and the billet bar, as well as between each billet bar, are completely eliminated, the spring mechanism is compressed and contracts, driving the billet pusher and trigger mechanism to retract. When the billet pusher retracts to its position, the trigger mechanism triggers the proximity switch to send a sensing signal. At this time, the servo electric cylinder records the position and calculates the movement distance of the emptying mode based on the length of the billet bar and the movement distance of the pushing mode. Then the servo electric cylinder returns to the initial position, the emptying head pusher cylinder retracts, and performs periodic reciprocating motion according to the calculated movement distance of the emptying mode, thereby driving the billet pusher to push the emptying rod for repeated emptying and feeding operations. The spring force is determined by the model of the emptying rod, the spring length is determined by the maximum billet length and the length of the heating furnace, and the length of the emptying rod is calculated by combining the furnace length and the length of the feeding slide.

[0024] This invention adopts the process characteristics of conventional pusher rod feeding mechanisms, using an electric servo cylinder for propulsion power to precisely perform thermal emptying of billets of different lengths, effectively controlling energy loss. This invention uses a two-part slide, one side storing the emptying rod and the other side storing the billets ready for heating. The mechanism employs pneumatic feeding and is entirely automated, requiring no manual labor. The invention cleverly designs the pusher head to adapt to the propulsion of bars of different diameters, while simultaneously loading a mechanism to eliminate clearance gaps in the emptying process. This allows the equipment to adapt to the emptying and heating of billets of various lengths, avoiding the waste of manpower and energy that traditional induction heating equipment requires manual emptying after heating is stopped.

[0025] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any variations or modifications to the above embodiments that are within the spirit and essence of the present invention will fall within the scope of the claims of the present invention.
