Description

Technical Field

[0001] This invention relates to B21D26, and more specifically to a reverse-stacking device for thickening materials. Background Technology

[0002] Many metal parts materials need to be stamped in advance to change their shape to meet the application requirements. Currently, common stamping technologies for these metal parts materials, such as blanking, bending, and stretching, can only make the metal parts thinner.

[0003] For products that require thicker materials in certain areas, the only solution is to use thicker materials to process the product while compressing the other parts to make them thinner. Although this method can meet the product's drawing requirements, it has the following disadvantages: (1) the raw materials are thicker, resulting in higher material costs; (2) the equipment used is of high tonnage; and (3) production efficiency is low.

[0004] The invention patent with patent number CN108435870B provides a multi-pass spinning deposition thickening forming method. By using multiple passes of spinning wheel grooves of different shapes, the edge of the rim of the disc-shaped part of the automobile component is thickened, thereby optimizing the thickening process and improving the stability of the part.

[0008] Preferably, the reverse molding station includes an upper mold part and a lower mold part.

[0009] As a preferred embodiment of the present invention, the top block is a cylinder.

[0010] As a preferred embodiment of the present invention, the diameter of the cylinder is 2-55mm.

[0011] Preferably, the diameter of the cylinder is 4-50 mm.

[0012] As a preferred technical solution of the present invention, the left side of the anti-pier work station is movably connected to the right side of the partition.

[0013] As a preferred technical solution of the present invention, the movable connection is selected from one of threaded connection, spline connection, snap hook connection, and sliding connection.

[0014] Preferably, the active connection is a sliding connection.

[0015] As a preferred embodiment of the present invention, a partition base is provided at the lower end of the partition.

[0016] As a preferred embodiment of the present invention, a material sheet is placed between the top block and the punch.

[0017] As a preferred technical solution of the present invention, the anti-brick device includes two states: an open state and a closed state.

[0018] Preferably, when the anti-damping device is in the open state, the upper end of the partition base is close to the lower end of the base plate; when the anti-damping device is in the closed state, the height difference between the upper end of the partition base and the lower end of the base plate is 8mm.

[0019] A second aspect of the present invention provides an application of a back-anchoring device for thickening materials, wherein the back-anchoring device is applied to the thickening of stretchable materials such as ordinary carbon steel, stainless steel, copper, and aluminum.

[0020] Preferably, the original thickness of the stretchable material is 0.3-2 mm.

[0021] After using the anti-damping device provided by this invention, the stretchable material can be thickened to 1-1.3 times its original thickness.

[0022] Working Principle: After conventional punching and stretching processes, the stretchable material enters the stretching station one for further stretching, and then enters the reverse upsetting station. In the open mold state, the upper end of the partition base is close to the lower end of the base plate, and there is a gap between the top block and the punch. The stretchable material sheet is placed in the gap between the top block and the punch. During the reverse upsetting process, the reverse upsetting device alternates between the open and closed mold states. The lower mold part is close to the right side of the partition and slides vertically upward along the right side of the partition, while the upper mold part moves vertically downward until the reverse upsetting station is in the closed state. At this time, the height difference between the upper end of the partition base and the lower end of the base plate is 8mm. After repeated mold opening and closing states, the material sheet is compacted and enters the stretching station two for further stretching. After conventional shaping, flipping, punching, and forming processes, it is thickened to 1-1.3 times its original thickness.

[0026] (3) By adding a reverse stacking process between two stretching operations, the target part of the product is locally thickened without changing the thickness of other parts of the product.

[0027] (4) The anti-brickling station in the anti-brickling device for thickening materials provided by the present invention can be replaced according to the original thickness of the material sheet and the desired thickening effect, thereby improving the utilization rate of the device.

[0028] (5) The anti-bulking device for thickening materials provided by the present invention has high production efficiency and material utilization rate when thickening products. Attached Figure Description
