Detailed Description
The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
As shown in fig. 1 and 2, an auxiliary tool for a final forming process of a free forging large-scale module comprises an upper flat anvil 2 and a lower flat anvil 1 which are arranged on a forging machine and used for forging products, wherein a concave core 3 which is concave inwards is arranged at the bottom of at least one of the upper flat anvil 2 and the lower flat anvil 1, and the upper flat anvil 2 or the lower flat anvil 1 forms a concave core anvil 4 through the concave core 3.
The conventional flat anvil is distinguished, and the middle part of the bottom of the concave core anvil 4 is designed in an inner arc shape; the concave core 3 of the product caused by the local heat deformation bulge in the middle of the upper anvil and the lower anvil during the molding of the module product can be effectively avoided. The problem that the upper flat anvil 2 and the lower flat anvil 1 are heated at a high temperature for a long time to generate thermal expansion bulges in the hot working process is well solved through the concave core 3, so that the concave core 3 phenomenon of a product is avoided when the product is forged and shaped, the tissue stress of the product after the heat treatment is uniform, the defect of the product center concave core 3 can not occur any more, the bulge caused by the thermal expansion of the flat anvil when the anvil is heated in a row is solved, and the product concave core 3 is avoided when the product is forged and shaped.
Further, the concave core 3 is an arc-shaped concave, the concave core 3 is arranged in the middle of the bottom of the upper flat anvil 2 or the lower flat anvil 1, and the concave depth of the concave core 3 is 15+/-2 mm; the concave core 3 is an arc-shaped concave, the concave core 3 is arranged in the middle of the bottom of the upper flat anvil 2 or the lower flat anvil 1, and the concave depth of the concave core 3 is 15+/-2 mm; the forging plane flatness of the upper flat anvil 2 or the lower flat anvil 1 which is not the hollow anvil 4 is 5-30mm, and the forging plane flatness of the hollow anvil 4 is 3-10mm.
The size of the forged piece is shaped by the concave core anvil 4, and the concave core of the product produced by forging and heat treatment is obviously improved. The flatness of the flat anvil forging is 5-30mm (the larger the thickness and width of the product, the larger the degree of dishing), and the flatness of the flat anvil forging is 3-10mm (the smaller the thickness and width, the better the flatness) when the concave core 3 is adopted for forging. After the shaping process of the concave core anvil 4, the forging allowance of the product is reduced from 30-50mm of the traditional process to 15-25mm of the new process, and the forging allowance is reduced by at least one time.
In a further improvement, the upper flat anvil 2 adopts a concave core anvil 4, and the bottom of the lower flat anvil 1 is of a plane structure.
In order to prevent the upper flat anvil 2 and the lower flat anvil 1 from being deformed due to long-term heating in the use process, the flat anvil forging is adopted when a product is heated, forged and unfired, and the concave core anvil 4 is adopted when the product is shaped. The product shaping is carried out by adopting the upper concave flat, only the upper flat anvil 2 adopts the concave core anvil 4, the problem that the product center is convex due to overlarge radian of the concave core 3 during shaping and the size cannot be recovered after the product is cooled can be effectively prevented, particularly when the thickness of the product is less than or equal to 350mm and the width is more than or equal to 1600mm, the shaping operation is carried out by adopting the upper concave flat, so that the problem of the concave core 3 of the product with the thickness less than or equal to 350mm is solved.
Meanwhile, the upper flat anvil 2 and the lower flat anvil 1 are processed by adopting 5CrMnMo forgings, so that the upper flat anvil 2 and the lower flat anvil 1 have higher strength and high wear resistance.
