Description

Technical Field

[0001] This utility model relates to the field of waste separation technology for fine stamping machines, and in particular to a waste separation device for fine stamping machines. Background Technology

[0002] Due to the special nature of the fine blanking process, the fine blanking die will output qualified products and scrap materials at the same time during the operation. The fine blanking scrap separation device is an important component of the fine blanking process. It can separate qualified products from scrap materials and prevent scrap materials from being mixed in with the products.

[0003] A search revealed Chinese Patent Publication No. CN215199144U, which discloses a waste separation device for a fine blanking machine. This utility model, by arranging a floating plate, floating plate pulley, product unloading plate, lifting crossbar, lifting rope, waste baffle, and other components on the discharge side of the fine blanking machine, achieves strong adaptability and accurate waste separation. It can be used for different types of products, has a wide range of applications, and can ensure that waste is completely blocked outside the waste baffle, preventing mixing with the product. It does not require a dedicated machine, improves equipment utilization, reduces equipment investment, and achieves excellent waste separation results at a lower cost.

[0004] Although the above-mentioned device can separate waste from products, in the actual fine blanking process, due to insufficient blanking force, excessive blanking speed, or poor lubrication, burrs are easily generated on the products. Products with burrs cannot meet the requirements of qualified products and therefore need to be processed again. However, the device cannot separate products with burrs, which makes it easy for defective products to be mixed in with the finished products. The separation effect needs to be improved. Therefore, a waste separation device for fine blanking machines is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of a waste separation device for a fine blanking machine, including a rear door 1 of the fine blanking machine. A first conveyor 2 and a second conveyor 3 are fixedly installed on the inner wall of the rear door 1. Qualified products will enter the interior of the rear door 1 through the discharge plate 7 and fall onto the second conveyor 3. The second conveyor 3 transports the qualified products. A partition 4 is fixedly installed on the inner wall of the rear door 1. Under the obstruction of the partition 4, waste will fall onto the first conveyor 2. The first conveyor 2 transports the waste. An opening 5 is opened on the side of the rear door 1 near the first conveyor 2. By opening the opening 5, waste can be blown into the interior of the rear door 1. A hoisting steel cable 6 is fixedly installed on the outer wall of the rear door 1. A discharge plate 7 is fixedly installed at the end of the hoisting steel cable 6 away from the rear door 1. A floating plate 71 is provided at the top of the discharge plate 7. A screening mechanism and an auxiliary mechanism 10 are provided inside the discharge plate 7.

[0033] Reference Figures 2-4 The screening mechanism includes a positioning component 8, which includes a rotating rod 81 that passes through and is rotatably connected to the inner wall of the blanking plate 7. A worm gear 82 is fixedly installed at the right end of the rotating rod 81, and a positioning plate 83 is fixedly installed on the outer wall of the rotating rod 81. The rotation of the rotating rod 81 can drive the positioning plate 83 to swing up and down inside the blanking plate 7. The positioning plate 83 can be used to control the thickness of the fine blanking product. Once the fine blanking product produces burrs that cause its surface to be uneven, the positioning plate 83 can block it from the blanking plate 7. A protrusion 84 is fixedly installed on the side wall of the material feed plate 7. A worm gear 85 is rotatably connected through the inner wall of the protrusion 84. The worm gear 85 meshes with a worm wheel 82. When the worm gear 85 rotates, it can drive the rotating rod 81 to rotate on the inner wall of the material feed plate 7 in conjunction with the worm wheel 82 meshing with it. A knob 86 is fixedly installed on the top of the worm gear 85. The worm gear 85 can be easily rotated by setting the knob 86. An inclined plate 87 is fixedly installed on the inner wall of the material feed plate 7. The qualified product can slide to the middle part of the positioning plate 83 by the guidance of the two sets of inclined plates 87.

[0034] Reference Figure 2 The screening mechanism also includes a feeding assembly 9, which includes a cylinder 91. The cylinder 91 is fixedly installed on the inner wall of the feeding plate 7. A push block 92 is fixedly installed on the piston end of the cylinder 91. Activating the cylinder 91 can drive the push block 92 to gradually approach or move away from the storage box 94. A push rod 93 is fixedly installed on the side wall of the push block 92. The bottom of the push rod 93 is in contact with the inside of the feeding plate 7. By moving the push block 92 in conjunction with the push rod 93, the product blocked by the positioning plate 83 can be pushed into the storage box 94 for temporary storage. The storage box 94 is fixedly installed on the inner wall of the feeding plate 7. The top of the storage box 94 is open and flush with the inner wall of the feeding plate 7. The storage box 94 can be used to temporarily store products with burrs for secondary processing.

[0035] Reference Figures 3-4The auxiliary mechanism 10 includes a crossbar 101, which is fixedly installed on the right side of the positioning plate 83. When the rotating rod 81 drives the positioning plate 83 to swing, the positioning plate 83 will drive the crossbar 101 to move synchronously around the rotating rod 81. A hollow rod 102 is slidably connected to the outer wall of the unloading plate 7. The outer wall of the crossbar 101 is attached to the inner wall of the hollow rod 102. When the crossbar 101 moves, it will push the hollow rod 102, so that the hollow rod 102 slides on the outer wall of the unloading plate 7. A positioning rod 104 is fixedly installed on the outer wall of the hollow rod 102. The upper surface of the positioning rod 104 is flush with the bottom of the crossbar 101. A scale 103 is fixedly installed on the outer wall of the unloading plate 7. The bottom end of the scale 103 is flush with the inside of the unloading plate 7. The movement distance of the positioning rod 104 can be measured through the scale 103.

[0036] Working principle: During fine blanking, qualified products are above the lower die of the fine blanking machine, and scrap is below the lower die. The floating plate 71 is kept between the product and the scrap during the stamping process. After fine blanking is completed, the air blowing device on the fine blanking machine blows the scrap onto the lower plate 7, while the scrap generated during fine blanking is blown to the bottom of the lower plate 7. At this time, qualified products will enter the interior of the rear door 1 of the fine blanking machine through the lower plate 7 and fall onto the second conveyor 3. The second conveyor 3 transports the qualified products, and the scrap is blown into the interior of the rear door 1 of the fine blanking machine through the opening 5. At this time, under the obstruction of the partition 4, the scrap will fall onto the first conveyor 2. The first conveyor 2 transports the scrap, thereby completing the separation of the product and the scrap.

[0037] Rotating the worm gear 85 by knob 86 causes it to rotate on the inner wall of the protrusion 84. Simultaneously, the worm gear 85, in conjunction with the meshing worm wheel 82, drives the rotating rod 81 to rotate on the inner wall of the blanking plate 7. The rotation of the rotating rod 81 causes the positioning plate 83 to swing up and down inside the blanking plate 7, thus adjusting the distance between the bottom of the positioning plate 83 and the blanking plate 7. Adjusting the bottom of the positioning plate 83 to a suitable height according to the thickness of the blanking product ensures that the product fits snugly inside the positioning plate 83 and passes just through the gap between the positioning plate 83 and the blanking plate 7. If burrs are present after blanking, they prevent the product from fully fitting inside the blanking plate 7. In this case, the product will be obstructed by the positioning plate 83 as it slides through the blanking plate 7 into the rear door 1 of the blanking machine. This effectively isolates products with burrs, preventing defective products from mixing with qualified products.

[0038] After the positioning plate 83 blocks the product with burrs, the cylinder 91 is activated to drive the push block 92 to gradually approach the storage box 94. At this time, the push block 92 will drive the push rod 93 to move synchronously. The movement of the push rod 93 can push the product blocked by the positioning plate 83 into the storage box 94 for temporary storage, thereby separating the product with burrs and improving the overall separation effect of the device.

[0039] While the rotating rod 81 drives the positioning plate 83 to swing, the positioning plate 83 drives the crossbar 101 to move synchronously around the rotating rod 81. At this time, the crossbar 101 will move against the inner wall of the hollow rod 102 and push the hollow rod 102, so that the hollow rod 102 slides on the outer wall of the blanking plate 7. While the hollow rod 102 is sliding, it will drive the positioning rod 104 to move synchronously. At this time, the movement distance of the positioning rod 104 can be measured through the scale 103. Since the upper surface of the positioning rod 104 is flush with the bottom end of the crossbar 101 and the bottom of the scale 103 is flush with the inside of the blanking plate 7, the gap width between the bottom end of the positioning plate 83 and the blanking plate 7 can be known. Therefore, the gap between the blanking plate 7 and the positioning plate 83 can be precisely adjusted according to the thickness of the fine blanking product, further improving the separation efficiency of the positioning plate 83.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
