Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of stamping blanking, and in particular relates to a blanking protection device for a stamping die. Background Art
[0002] In the stamping production process, the stamped products are directly dropped vertically. In the dropping process, the sheet products are very easy to flip or tilt, and it is very easy to cause collision after flipping or tilting. Products with weak edge structures are prone to damage or bending after collision, resulting in defective products. In order to reduce the phenomenon of collision when the products are dropped, a collection frame made of soft foam, pearl cotton and other materials is often used to collect the products after stamping. However, since the material of soft foam and pearl cotton is soft and easy to be damaged, it needs to be replaced frequently, which increases the workload. At the same time, in order to increase the cushioning effect, thicker soft foam or pearl cotton needs to be made, which occupies a large area, resulting in insufficient space for dropping in the mold. In order to solve such problems, a dropping protection device for a stamping mold is proposed. Utility Model Content

[0025] The blanking protection device for a stamping die according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.
[0026] like Figure 1 As shown, the blanking protection device for a stamping die according to the embodiment of the utility model includes: a guide seat 1, the guide seat 1 forms a limiting channel 2 along the blanking direction of the product, both ends of the limiting channel 2 pass through the guide seat 1, the inner surface of the limiting channel 2 guides the product, there is a certain distance between the inner surface of the limiting channel 2 and the outer surface of the product, the distance between the inner surface of the limiting channel 2 and the outer surface of the product is not more than 4 mm, and the hardness of the guide seat 1 is less than the hardness of the product.
[0027] In this embodiment, the size of the guide seat 1 and the size of the limiting channel 2 can be customized according to the size of the product. The guide seat 1 is installed below the stamping die. A receiving surface for collecting products is placed below the guide seat 1. The product formed after stamping falls into the limiting channel 2. The limiting of the product by the inner surface of the limiting channel 2 reduces the phenomenon of flipping or large tilting of the product during the falling process, so that the product falls naturally in a nearly horizontal state and contacts the receiving surface over a large area, thereby avoiding damage or bending caused by the corners of the product hitting the receiving surface; since the distance between the inner surface of the limiting channel 2 and the outer surface of the product is not greater than 4 mm, the displacement of the product is small, the impact amplitude of the product with the inner surface of the limiting channel 2 is reduced, and the damage to the product is further reduced; at the same time, since the hardness of the guide seat 1 is less than that of the product, even if the product has a slight collision with the inner surface of the limiting channel 2 during the falling process, it will not cause damage or bending to the product, thereby reducing losses and improving the integrity of the finished product.
[0028] The guide seat 1 is installed under the stamping die. When the stamping die is replaced, there is no need to disassemble the guide seat 1. The guide seat 1 can continue to be used when the stamping die is used next time, thereby reducing the disassembly and assembly process and avoiding the loss of the guide seat 1. The guide seat 1 can be replaced only when it is damaged, thereby improving the utilization rate of the guide seat 1 and saving production costs while ensuring the yield rate.
[0029] A conveyor belt 3 is provided below the guide seat 1. There is a certain distance between the conveyor belt 3 and the guide seat 1. The conveyor belt 3 is used to receive the product after being guided by the limiting surface.
[0030] In this embodiment, the conveyor belt 3 replaces the receiving surface. The conveyor belt 3 is set to receive the product so as to transport the product out from under the stamping die, so that each product falls on the conveyor belt 3, thereby avoiding the phenomenon of multiple products colliding when the products are not collected in time.
[0031] A passage 4 is formed on the side surface of the lower end of the limiting channel 2 along the output direction of the product. The passage 4 runs through the side surface of the guide seat 1 so that the conveyor belt 3 can drive the product to leave the guide seat 1.
[0032] The interval between the conveyor belt 3 and the guide seat 1 is not greater than the thickness of the product.
[0033] In this embodiment, the aisle 4 is provided so that the interval between the conveyor belt 3 and the guide seat 1 is not greater than the thickness of the product, and the product can be taken out at the same time; this avoids the product flipping in the gap between the conveyor belt 3 and the guide seat 1 due to the large distance between the conveyor belt 3 and the guide seat 1, and ensures that the product falls smoothly on the conveyor belt 3.
[0034] The passage 4 is smoothly connected to the inner surface of the limiting channel 2 , and the width of the passage 4 is the same as the width of the limiting channel 2 .
[0035] When the product falls, the limiting channel 2 limits the product by no less than one half of the circumference of the product.
[0036] The distance between the inner surface of the limiting channel 2 and the outer surface of the product is 2-3 mm.
[0037] In this embodiment, taking a circular product as an example, the limiting channel 2 is semicircular, and the diameter of the limiting channel 2 is 4-6 mm larger than the diameter of the product. At this time, the width of the aisle 4 is the same as the diameter of the limiting channel 2, so that the product can be taken out of the aisle 4. At the same time, the limiting range of the semicircular limiting channel 2 for the circular product is sufficient to limit the flipping or large tilting of the circular product; the distance between the inner surface of the limiting channel 2 and the outer surface of the product is set to 2-3 mm to avoid the distance between the limiting channel 2 and the product being too small, resulting in a jamming phenomenon when the product descends, or the distance between the limiting channel 2 and the product being too large, resulting in a flipping or large tilting phenomenon when the product descends.
[0038] The material of the guide seat 1 is less hard than that of the product to reduce collision and wear on the product; the material of the guide seat 1 is preferably polyester or plastic to ensure that the guide seat 1 has a certain hardness, which is convenient for long-term use and increases the service life of the guide seat 1. At the same time, the injection molding process can be used when producing the guide seat 1, and it can be integrally formed to facilitate production.
[0039] The material of the conveyor belt 3 is a soft surface, and the material of the conveyor belt 3 is preferably a soft leather surface, which reduces the wear of the product and has a slight buffering effect, so that the product will not bounce up when used.
[0040] A mounting hole 5 is provided on the upper surface of the guide seat 1 for mounting the guide seat 1 on a stamping die.
[0041] In summary, by providing the guide seat 1 and the conveyor belt 3 with a soft leather surface, product damage and deformation are greatly reduced, and production efficiency and product qualification rate are improved; at the same time, the reduction in the defective rate reduces the workload of separate off-line appearance inspection personnel.
