However, due to the kerf shape and special shearing conditions, the product produces granular hard burrs there.
However, burrs are generated in the place where the material is attached, which makes the product not beautiful, but also scratches the hand, and cannot meet the customer's requirements for high-quality products.
Therefore, if there is no burr in the place where the product is loaded, it is necessary to use manual deburring or add a set of procedures to deburr. This will not only make the process complicated, increase labor costs, and increase processing costs, but also greatly increase the cost of the mold.

Embodiment Construction
[0030] The method of continuous in-mold product deburring around the entire circumference is unique in that it includes the following steps: First, use a rising punch 2 to reverse cut product 1 from bottom to top. When the mold is first clamped, product 1 is reverse cut. Face becomes collapsed face 3, ie figure 2 , 3 Shown. Subsequently, the downward press punch 4 is used to transversely break the reverse cut of the product 1, and the side burrs of the product 1 are removed during the second mold clamping. As a result, the product 1 has been completely deburred when it is finally formed, that is, figure 2 , 4 Shown.
[0031] In further combination with a preferred embodiment of the present invention, the working end of the rising punch 2 is provided with a slope. In this way, it is convenient for the ascending punch 2 to reverse cut the product 1, and the burr surface formed by the reverse cut becomes the collapsed surface 3, and it is ensured that 15%-20% of the products are ...

The invention relates to a method and a device for complete cycle deburring of a product in a continuous die. The method comprises the following steps: firstly, adopting a rising punch head to performreverse cutting so as to form a rollover surface on the product; and secondly, adopting a pressing punch head to perform transverse tension fracture so as to remove side burrs of the product. The device comprises an upper die holder and a lower die holder, and is characterized in that the upper die holder is provided with a discharge board insert on a first processing station, the lower die holder is provided with a holding pad on the first processing station, a rising die cutting channel is arranged in the holding pad, and the rising punch head is arranged in the rising die cutting channel;and the upper die holder is provided with a pressing die cutting channel on a second processing station, the pressing punch head is arranged in the pressing die cutting channel, and the lower die holder is provided with a concave template insert on the second processing station. By adopting the method and the device, the complete cycle deburring of the product in the continuous die can be achievedonly through the cooperation of the rising punch head and the pressing punch head in the process of processing matched molds without artificial deburring and a process of deburring. The device has theadvantages of simple structure, simple implementation, high production efficiency and advantageous promotion.
Description
Technical field [0001] The invention relates to a method and equipment for deburring, in particular to a method and equipment for deburring a continuous in-mold product all around, and belongs to the technical field of mechanical processing. Background technique [0002] At present, traditional cutting is used in mold processing, which is to directly cut off the edge material of the product to complete the processing. However, due to the shape of the cut and the special shear conditions, the product produces granular hard burrs there. The burrs produced in the place with the material make the product unsightly and scratch the hand, and it cannot meet the high-quality requirements of customers. Therefore, if there is no burr in the product with the material, it is necessary to use manual deburring, or add a set of procedures to deburr, which not only complicates the process, increases labor costs, and increases processing costs, but also greatly increases the cost of the mold. ....
