Furthermore, existing semi-automated equipment is difficult to achieve stable workpiece positioning during processing, affecting the quality of removal. Moreover, the semi-finished and finished products after removal need to be manually separated and recycled, which is a cumbersome process that increases the workload of workers and reduces work efficiency.
[0003] Therefore, this application provides a piston blank riser removal tooling device to meet the requirements. Utility Model Content

Furthermore, existing semi-automatic equipment is difficult to achieve stable workpiece positioning during processing, affecting the quality of removal. In addition, the semi-finished and finished products after removal need to be manually separated and recycled, which is a cumbersome process that increases the workload of workers and reduces work efficiency.
[0005] To achieve the above objectives, this application provides the following technical solution: a piston blank riser removal tooling device, comprising a base, pistons, and support legs.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0024] refer to Figure 1-7 The piston blank riser removal tool shown includes a base 1 and a piston 13. The bottom of the base 1 is connected to a support leg 2 for support. The base 1 is provided with a guide rail 12. There are two sets of guide rails 12, and the two sets of guide rails 12 are installed side by side on the base 1. A cutting mechanism 6 is provided above one end of the guide rail 12, and a feeding mechanism 5 is provided at the other end of the guide rail 12. The feeding mechanism 5 is installed on the base 1. The cutting mechanism 6 is connected to the base 1 through a support plate 11. The base 1 is also provided with a waste outlet 101 for discharging waste material. The waste outlet 101 is located below the U-shaped blade 62. The two sides of the base 1 are connected to a recovery plate 4 for recycling materials. The base 1 is also connected to a discharge plate 3 for discharging materials. The discharge plate 3 is located below the support plate 11. The feeding mechanism 5 and the cutting mechanism 6 are also connected through a transmission mechanism 7.
[0025] As one embodiment of this invention, in order to facilitate the cutting of the riser 14 of the piston 13 by the equipment, the cutting mechanism 6 also includes a mounting plate 61, a U-shaped knife 62, and a pressing knife 63. The U-shaped knife 62 and the pressing knife 63 are mounted on the mounting plate 61, and there are two sets of pressing knives 63. The two sets of pressing knives 63 are located on both sides of the U-shaped knife 62. A pre-tightening block 64 is provided on one side of the pressing knife 63, and a pressing block 65 is provided on the other side of the pressing knife 63. The pre-tightening block 64 is located between the U-shaped knife 62 and the pressing knife 63, and is located directly above the guide rail 12. It is used to fix the piston 13 when pressing down to cut the riser 14 on the piston 13, so as to prevent the piston 13 from deflecting. The size of the U-shaped knife 62 is adapted to the riser 14. The distance between the U-shaped knife 62 and the pressing knife 63 is the same as the size of the piston 13. The pressing block 65 is used to assist in separating the semi-finished piston 13 from the finished piston 13. The mounting plate 61 is also provided with a limiting rod 66 for connecting with the transmission mechanism 7.
[0026] As one embodiment of this invention, in order to reduce the probability of workers being injured when filling the equipment, the feeding mechanism 5 also includes a buffer block 51. The buffer block 51 has a buffer groove 52 for storing the piston 13 in its blank state. The inner walls of the buffer groove 52 are respectively provided with sliding holes 54 and output holes 53 for outputting the piston 13 to the guide rail 12. The position of the output hole 53 corresponds to the position of the guide rail 12. There are two sliding holes 54. Push rods 55 slide in the sliding holes 54. The push rods 55 are connected to each other by a connecting rod 56. The connecting rod 56 is used to connect to the transmission mechanism 7.
[0027] As one embodiment of this invention, in order to enable the equipment to automatically feed materials, the transmission mechanism 7 also includes a linkage rod 71 and a slide rod 72. The mounting plate 61 is provided with a sliding groove 102 for the slide rod 72 to slide. The slide rod 72 is connected to the connecting rod 56. One end of the linkage rod 71 is hinged to the slide rod 72, and the other end of the linkage rod 71 is hinged to the limiting rod 66. This allows the limiting rod 66 to move synchronously when the mounting plate 61 is pushed downward by the electric push rod 10. Through the connection between the linkage rod 71 and the slide rod 72, the limiting rod 66 allows the push rod 55 to reciprocate synchronously when the mounting plate 61 moves up and down, thus conveying the material in the buffer tank 52 to the bottom of the cutting mechanism 6.
[0028] The working principle of this utility model is as follows: In use, the pistons 13 in their blank state are first placed in the buffer slots 52 on the buffer block 51. Four pistons 13 in their blank state are arranged in a group. Then, the electric push rod 10 on the support plate 11 lifts the cutting mechanism 6 upwards. The limiting rod 66 in the cutting mechanism 6 drives the sliding rod 72 to slide in the sliding groove 102 via the linkage rod 71. The sliding rod 72 drives the push rod 55 to move via the connecting rod 56. The push rod 55 pushes the pistons 13 in their blank state out of the output hole 53 from the buffer slot 52, causing the pistons 13 to be pushed along the guide rail 12 to the cutting machine. Below the structure 6, the blank piston 13 undergoes initial processing. The U-shaped blade 62 and pressure blade 63 on the mounting plate 61 of the cutting mechanism 6 move downward to cut off the riser 14 between the two middle pistons 13. The cut-off riser 14 is output through the waste port 101. Then, the two semi-finished pistons 13 on both sides, still with risers 14, fall into the recycling box 9 through the recycling plates 4 on both sides. While the cutting mechanism 6 moves downward, it also moves backward through the linkage rod 71 and slide rod 72 in the transmission mechanism 7, driving the push rod through the connecting rod 56. Push rod 55 retracts into buffer tank 52. As cutting mechanism 6 moves upward, push rod 55 pushes the second set of blank pistons 13 out of buffer tank 52 and moves them along guide rail 12 to below cutting mechanism 6. At the same time, it pushes the finished pistons 13 of the previous set onto discharge plate 3, and then they fall into discharge box 8 through discharge plate 3. After the blank pistons 13 are processed, the semi-finished pistons 13 in recycling box 9 are put back into buffer tank 52. Then, electric push rod 10 is activated to raise cutting mechanism 6 again, so that limit rod 66 drives the connecting rod 71 and slide rod 72 to move the connecting rod 72. Rod 56 and push rod 55 work together. Push rod 55 pushes the semi-finished piston 13 in buffer tank 52 out of output hole 53 and moves it along guide rail 12 to the bottom of cutting mechanism 6, ready for secondary cutting processing. When the semi-finished piston 13 moves to the bottom of cutting mechanism 6, the mounting plate 61 and pressure knife 63 of cutting mechanism 6 move down again, so that U-shaped knife 62 and pressure knife 63 on both sides accurately cut off the remaining riser 14 on semi-finished piston 13. Piston 13 completes final processing. Finished piston 13 is conveyed to discharge box 8 through discharge plate 3, completing the entire cutting and material distribution process.
