Description

Technical Field

[0001] The utility model relates to the technical field of punching and shaping devices, in particular to a hot punching and shaping device for magnesium-aluminum alloy products. Background Art

[0002] Existing magnesium-aluminum alloy products are die-cast into large and thin pieces. Figure 1 As shown, it is composed of a product 1, a material handle 2, exhaust waste 3 and side waste 4. The existing method of roughly punching the die-cast product is to take out the die-cast product and let it stand, and then manually take out the material and punch it after cooling.

[0003] However, since magnesium-aluminum alloy products will bend and twist to varying degrees after die-casting, the method of punching after cooling not only takes up space in the production workshop, but also easily causes three damages to the product when the material head is turned over. In addition, the product deformation caused by cold punching cannot be leveled by rough punching and cold pressing. In addition, the exhaust waste part of the product is large and thin, and it is not easy to clean after manual material removal and punching. Utility Model Content

[0007] Preferably, the upper punch and the lower punch are fixed to the side surfaces of the upper mold core and the lower mold core respectively by screws in a side-locking manner.

[0008] Preferably, limiting columns are respectively provided on the lower template and the upper template.

[0009] Preferably, a positioning pin is fixedly provided on the lower template at the position of the positioning hole on the material handle corresponding to the product.

[0010] Preferably, the upper mold core is provided with pin holes corresponding to the products, and floating pins are respectively inserted into the pin holes, and the floating pins are fixedly connected to the upper mold plate.

[0011] Preferably, exhaust waste material drop-out openings are correspondingly arranged on the bottom plate and the lower template, and the exhaust waste material drop-out openings are arranged correspondingly to the position directly below the exhaust waste.

[0012] The beneficial effects of the utility model are as follows: (1) the utility model changes manual punching into automatic punching; (2) the exhaust waste can slide down by itself after punching, reducing manual cleaning and product crushing; (3) hot punching reduces poor flatness and three kinds of damage caused by material head turnover, improving the yield rate, and at the same time, the product placement groove between the upper mold core and the lower mold core can be used to level the product through hot stamping.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0019] Example: Figure 2-4 As shown, a hot punching and shaping device for magnesium-aluminum alloy products includes a base plate 5 and a lower pressure plate 6, a lower template 7 is fixedly installed on the base plate, an upper template 8 is fixedly installed on the bottom of the lower pressure plate, a lower mold core 9 is fixedly installed on the lower mold, an upper mold core 11 is fixedly installed on the bottom of the upper mold, a product placement groove is provided between the upper mold core and the lower mold core, the product placement groove is used to place the product, an upper punch 12 and a lower punch 16 are detachably fixedly installed on the sides of the upper mold core and the lower mold core, and the upper punch and the lower punch are respectively provided corresponding to the punching positions of the product handle, exhaust waste and side waste.

[0020] The upper punch and the lower punch are respectively fixed to the side surfaces of the upper die core and the lower die core by screws in a side-locking manner. The lower die plate and the upper die plate are respectively provided with limit posts 10.

[0021] A positioning pin 15 is fixedly arranged on the lower template at the position of the positioning hole on the material handle of the product.

[0022] The upper mold core is provided with pin holes 13 corresponding to the products, and floating pins 14 are respectively passed through the pin holes, and the floating pins are fixedly connected to the upper mold plate.

[0023] Exhaust waste material drop-out openings 17 are correspondingly arranged on the bottom plate and the lower template, and the exhaust waste material drop-out openings are arranged correspondingly to the position directly below the exhaust waste material.

[0024] When the utility model is used, the product is grabbed by the manipulator and placed in the lower die core, and the upper die core is lowered by the punch press to punch the product. When the product is hot, the upper die core and the lower die core are used to compact the product, and then the material handle and exhaust waste are cut off, thereby reducing the deformation and crushing of the die-cast product. After the product is punched, the product is taken out by the manipulator suction cup, and the adsorbed product is first placed in the turnover slide rail, and then the material handle is placed in the waste barrel, and the exhaust waste and side waste slide freely through the drop zone. The upper punch and the lower rough punch are fixed to the sides of the upper and lower die cores by side locking screws, which is convenient for subsequent adjustment of the die punching gap to reduce maintenance time. During hot punching, the limit column is adjusted to ensure the gap between the upper and lower die cores to prevent the product from being over-pressed and causing poor crushing. When punching the product, the floating pin is used to press the product on the lower die core after punching to prevent it from being brought into the upper die and causing product defects. The utility model can reduce manpower turnover and cold material time, save costs, improve flatness yield, and reduce crushing.

[0025] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
