Description

Technical Field

[0001] The utility model relates to the technical field of magnesium alloy product processing, and particularly relates to a continuous stamping device for magnesium alloy product processing. Background Art

[0002] Magnesium alloy products are alloy products composed of magnesium as the basic element and added with other alloy elements (such as aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium, etc.). Due to its unique physical and chemical properties, such as low density, high specific strength, large elastic modulus, good heat dissipation, good shock absorption, strong ability to withstand impact loads, and good corrosion resistance to organic substances and alkalis, magnesium alloy is widely used in multiple fields. When performing some processing operations on magnesium alloy plates, a stamping device is used to stamp and form the magnesium alloy plates, which can quickly and accurately complete processing processes such as punching holes. Compared with other processing methods, the stamping device has higher production efficiency and processing accuracy, and can meet the production requirements of large quantities and high precision.

[0003] When some existing magnesium alloy product stamping devices are in use, they lack a feeding mechanism, making it impossible for the stamping device to effectively convey and continuously stamp magnesium alloy plates with longer dimensions.

[0004] For example, a magnesium alloy plate stamping device disclosed in the patent with the publication number CN211437710U. In this magnesium alloy plate stamping device, the magnesium alloy plate is placed on the lower die assembly, and the upper die assembly cooperates with the lower die assembly to clamp the magnesium alloy plate. At this time, the upper and lower sides of the magnesium alloy plate are respectively pressed and extruded by the upper die assembly and the lower die assembly. The first hydraulic cylinder pushes the push plate and the punch downward, and the punch moves downward in the through hole of the upper die assembly until the lower end of the punch presses the magnesium alloy plate located in the through hole, completing the stamping process of the magnesium alloy plate. Since the position of the punch of the upper die assembly is fixed in advance, the punching position of the stamped magnesium alloy plate can be ensured to be accurate. In addition, when stamping the magnesium alloy plate, the upper die assembly and the lower die assembly clamp the magnesium alloy plate, which can effectively reduce the influence on the magnesium alloy plate outside the punching position, reduce the deformation degree of the magnesium alloy plate, and thus reduce the scrap rate.

[0005] The technical solution of the above magnesium alloy plate stamping device mainly focuses on the stamping process itself, including the design of the frame, the clamping method of the positioning mechanism, the movement of the stamping mechanism, and the setting of the buffer assembly, etc., aiming to ensure the stamping accuracy and efficiency, and at the same time reduce the scrap rate. However, this technical solution does not involve the design of the feeding mechanism, which results in obvious limitations when dealing with magnesium alloy plates with longer dimensions.

[0006] Specifically, the lack of a feeding mechanism makes it impossible for the stamping device to effectively convey and continuously stamp magnesium alloy plates with longer dimensions. During the actual production process, if the magnesium alloy plate has a longer dimension and the stamping device is not equipped with a corresponding feeding mechanism, then it is necessary to manually feed the magnesium alloy plate into the stamping area continuously. This not only has low efficiency but also increases the complexity and labor intensity of manual operation. At the same time, manual feeding may also affect the stamping accuracy and consistency because there may be slight position deviations in each feeding.

[0007] Therefore, it is necessary to invent a continuous stamping device for processing magnesium alloy products to solve the above problems. Utility Model Content

[0038] The working principle of the present utility model:

[0039] Refer to the attached drawings of the specification Figures 1-5 When using the present utility model, first place the magnesium alloy plate to be processed in front of the traction mechanism at the input end, that is, between the two feeding rollers 3, ensure that the material is flat and the edges are aligned, and start the first motor 2 through the control panel 19 to make the two feeding rollers 3 rotate synchronously in opposite directions, so as to smoothly transport the magnesium alloy plate from the input end to the stamping area;

[0040] When the magnesium alloy plate moves to the stamping area, first start the second electric push rod 10 to push the limit pressing plate 8 downward to extrude and limit the magnesium alloy plate, preventing it from shifting or warping during stamping. Then start the first electric push rod 9 to push the stamping template 7 quickly downward. Under the guidance of the guiding slide rod 11, the stamping template 7 remains stable and does not shift. The punch 12 penetrates the positioning hole 13 on the limit pressing plate 8 to stamp the magnesium alloy plate. After stamping, the waste material falls into the waste storage bin 15 through the through hole 14;

[0041] After the initial stamping is completed, continue to drive the magnesium alloy plate to move through the traction mechanism, move the un-stamped part of the magnesium alloy plate to the stamping area, and continue stamping. At the same time, the stamped part will pass through the brushing mechanism. At this time, start the second motor 4 to rotate the two brushing rollers 5 to sweep the debris on the surface of the magnesium alloy plate. The swept debris will fall into the dust collecting hopper 17, and the second blocking door 18 can be opened for cleaning later.
