[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0034] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0035] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a waste removal mechanism for stamping dies. Example 1

[0036] Combination Figures 1-5 As shown, the present invention provides a waste removal mechanism for stamping dies, including a three-stage fine filtration mechanism 100, a power supply mechanism 200 disposed within the three-stage fine filtration mechanism 100, and a multi-stage screening and vibration mechanism 300 disposed on the three-stage fine filtration mechanism 100. The three-stage fine filtration mechanism 100 is used to provide effective collection and filtration of waste materials falling from the die, the power supply mechanism 200 is used to provide active screening and vibration energy to the multi-stage screening and vibration mechanism 300, and the multi-stage screening and vibration mechanism 300 is used to actively filter the waste materials.

[0037] The three-stage fine filtration mechanism 100 includes two side plates 110 and two sets of discharge assemblies 140;

[0038] Two baffles 130 are symmetrically distributed on the inner side of the two side plates 110;

[0039] The discharge assembly 140 includes a protective shell 141 movably mounted on the outside of the two side plates 110, a gasket 144 is installed on the inner side of the protective shell 141, a fine-pore elastic filter 145 is provided on the inner side of the gasket 144, a gasket 146 is installed on the inner side of the fine-pore elastic filter 145, and a sealing gasket 147 is movably mounted in the gasket 146.

[0040] The sealing gasket 147 consists of a circular gasket and two T-shaped pins, and springs 148 are provided on the outside of the two T-shaped pins.

[0041] A support plate 142 is installed at the bottom of the protective shell 141, and a column 143 is installed at the inner end of the support plate 142.

[0042] The column 143 and the sealing gasket 147 are symmetrical in the vertical direction;

[0043] The inner wall of the protective shell 141 is provided with a sliding groove;

[0044] Two symmetrically distributed limiting pads are installed at both ends of the side plate 110, and the limiting pads are adapted to penetrate into the sliding grooves of the inner wall of the protective shell 141.

[0045] A foot 120 is mounted on another side plate 110, a first beam plate 150 is mounted on one of the housings 141, and a second beam plate 160 is mounted on the other housing 141;

[0046] The two adjacent ends of the first beam plate 150 and the second beam plate 160 are adapted to pass through the insertion holes inside the pad 120;

[0047] The multi-stage screening and vibration mechanism 300 includes a primary screen 320 and two secondary screen plates 350. The primary screen 320 is located on the top of the inner side of the two side plates 110, and the secondary screen plates 350 are located between the primary screen 320 and the gasket 144.

[0048] When the workpiece is formed in the mold, the waste material is squeezed out as the workpiece exits. After the waste material falls, the primary screen 320 can actively collect the waste material. As the motor 220 starts, its internal transmission shaft drives the crankshaft 230 to rotate at high speed. The crankshaft 230 will drive the clamp 360, suspension 310 and primary screen 320 to vibrate at high frequency. At this time, the waste material collected by the primary screen 320 can be actively screened and vibrated, while sand and coarse waste material can fall to the top of the two secondary screen plates 350. With the coordinated vibration of the two secondary screen plates 350, the sand and fine material can be screened and vibrated a second time.

[0049] Metal scrap can then be transferred along the slope of the top of the secondary sieve plate 350 to the cavities inside the two side plates 110 and the two baffles 130, while sand and gravel can be collected by the fine-pore elastic filter screen 145. Example 2

[0050] Combination Figure 2 and Figure 3 As shown, based on Embodiment 1, the power supply mechanism 200 includes a housing 210 mounted on one of the side plates 110, a motor 220 installed inside the housing 210, and a crankshaft 230 installed at the outer end of the transmission shaft inside the motor 220.

[0051] The other end of the crankshaft 230 is movably mounted in a groove on the outer wall of the side plate 110.

[0052] Preferably, the inner end of the chassis 210 is fixed to the outer wall of a side plate 110 by bolts or welding. When the motor 220 is connected to the external power line, the running motor 220 can actively drive the crankshaft 230 to rotate. The crankshaft 230, which is limited by the side plate 110, can drive the clamp 360 to vibrate stably during high-speed rotation. Example 3

[0053] Combination Figure 5 As shown, in the above embodiment, the multi-stage screening and vibration mechanism 300 also includes two suspensions 310 installed on both sides of the primary screen 320, and a clamp 360 is installed at the bottom of one of the suspensions 310.

[0054] The suspension 310 consists of a U-shaped truss, two vertical rods and two compression springs. The bottom end of the vertical rod is adapted to penetrate into the end plate of the outer wall of the side plate 110, while the bottom end of the compression spring is adapted to bear pressure on the end plate of the outer wall of the side plate 110.

[0055] Preferably, the length of the primary screen 320 is the same as the length of the two side plates 110, and the width of the primary screen 320 is adapted to fit in the gap between the inner sides of the two side plates 110. When the two protective shells 141 extend outward, the combined secondary screen plate 350 and protective frame 340 will also extend outward with the force. Finally, the device can be used with machine tools of different widths and increase the area for collecting waste materials on the molds on the machine tools.

[0056] Four symmetrically distributed sliders 330 are installed at the bottom of the primary screen 320;

[0057] The external movable parts of two adjacent sliders 330 are equipped with protective frames 340;

[0058] The top of the secondary sieve plate 350 is provided with an inclined slope, and the slope of the secondary sieve plate 350 towards the inner end face of the side plate 110 gradually increases.

[0059] Preferably, the protective frame 340 is used to limit and block the waste material after the initial screening. As the secondary screen plate 350 vibrates, the metal waste that has not been screened off can be transferred along the slope of the top of the secondary screen plate 350 under the action of the shock wave, and finally discharged quickly along the middle of the inner side of the two side plates 110.

[0060] The working principle and usage process of this utility model: The pad 120 is pre-installed at the machine tool mold discharge position using bolts until the discharge mechanism formed by the two side plates 110 and the two sets of discharge components 140 is located directly below the unloading.

[0061] When the primary screen 320 is at the bottom of the mold, as the waste material exits from the mold, the running motor 220 drives the crankshaft 230 to rotate at high speed. The clamp 360 will push one of the suspensions 310 to move up and down repeatedly, and the primary screen 320 will be located inside the two side plates 110 and vibrate at high frequency. At this time, the waste material falling inside the primary screen 320 can be actively screened, and the slightly smaller waste material will fall through the mesh of the primary screen 320 to the top of the two secondary screen plates 350. Due to the constraint of the two protective frames 340 on the two secondary screen plates 350, the slightly smaller waste material will vibrate along the inclined surface at the top of the secondary screen plate 350, and the even smaller waste material can fall through the mesh of the secondary screen plate 350 into the groove structure formed by the fine pore elastic filter 145 and the gasket 144.

[0062] The waste material transferred along the top slope of the secondary screen plate 350 will fall into the gap formed by the two side plates 110 and the two baffles 130. Finally, the metal waste and impurities of different sizes such as sand and gravel after punching can be screened in layers.

[0063] As waste gradually accumulates on the fine-pore elastic filter 145, the pad 146 and sealing gasket 147, which are subjected to weight, will continue to fall downwards. Eventually, the column 143 will push the sealing gasket 147 upwards until the sealing gasket 147 and the pad 146 open up, allowing the accumulated waste to be quickly transferred and discharged.

[0064] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
