Description

Technical Field

[0001] The utility model belongs to the field of stamping die design, and particularly relates to a waste chute with a tipping mechanism. Background Art

[0002] In the stamping production process, structural and process wastes are often generated. These wastes must be smoothly removed from the mold to ensure the continuous and safe production. In general mold design, there are four common methods for discharging waste: roller slide-out, vibration slide-out, conveyor slide-out and slide-out. Roller slide-out is generally used for the slide-out of blanks with regular shapes. The trimming waste is generally irregular in shape after stamping and is easy to fall into the roller gap and jam the roller. When vibrating and sliding out, the high-frequency vibration of the vibrator will produce a lot of noise and cause great damage to the mold and machine tools. When the conveyor belt is transmitted, the belt surface is easily scratched and damaged by the waste, and when the waste falls on the edge frame of the conveyor belt, the conveyor belt will fail. The slide plate has low design and manufacturing costs, reliable structure, and wide application. When using the slide plate to slide out, it is necessary to design a large drop on the mold to make the slide plate have a sufficiently large angle with the horizontal plane, so that the waste can be taken out of the mold by the component force along the direction of the slide plate under the action of gravity, so as to achieve normal continuous production. However, as the shapes of parts become more complex, the trimming waste of complex shapes is easy to hang on the slide, blocking the entire slide; the process requirements of some parts must be trimmed in the middle of the mold. In this case, the angle that the waste slide can be set to will become smaller. When the angle is not enough, gravity can no longer slide the waste out, which will also cause blockage. For these situations, the general method of widening the slide and increasing the drop during design is to increase the fault tolerance probability. However, such treatment generally requires the lower mold of the mold to be made higher and wider, which will increase the mold cost and unnecessary mold weight, resulting in the need for larger tonnage lifting equipment in later use, and the manufacturing and transportation costs will increase a lot.

[0003] Although there are many types of existing waste discharge mechanisms to choose from, they all have obvious disadvantages, mainly including the following points: 1. Ordinary skateboards have poor reliability; 2. The use range of roller skateboards is limited; 3. Vibrating skateboards are noisy and damage other equipment and tooling; 4. Conveyor belts are expensive, have limited structure, and require an external power supply. Utility Model Content

The exhaust pipeline 211 and the intake pipeline 212 are arranged up and down on the side of the cylinder 21; the head of the piston 213 is arranged in the cylinder 21, and the rod thereof extends from the top of the cylinder 21 and is connected to the swing mechanism 22; in this embodiment, the cylinder adopts an SGA small cylinder with a small size and can be applied to more mold conditions; the time point of the cylinder intake and exhaust is controlled by inputting parameters through the PLC, so that the time point of the reset of the slide groove matches the time point of the stamping waste sliding off.

[0027] Platforms are provided on both sides of the rear end of the piston 213 rod.

[0028] The swing mechanism 22 includes a base 221, a rocker arm 222, a group of connecting rods 223, a first pin 224, a second pin 225 and a third pin 226; the base 221 is fixed above the cylinder 21; the connecting rod 223 is arranged on both sides of the upper end of the base 221, one end of the connecting rod 223 is connected to the base 221 through the first pin 224, and the other end is connected to the middle section of the rocker arm 222 through the second pin 225; one end of the rocker arm 222 is connected to the piston 213 on the cylinder 21 through the third pin 226.
