Hot upsetting die seat of press

Abstract

The invention relates to a hot upsetting die seat of a press. The hot upsetting die seat comprises a knock-out rod (1), an upper die plate (3), an upper fixed seat (5), an upper safety nut (7), a lower safety nut (8), a lower fixed seat (10), an ejector sleeve (11), a lower die plate (12), a die handle (2) and a cushion plate A (4), wherein the upper fixed seat (5) is fixedly fastened on the upper die plate (3), and the lower fixed seat (10) is fixed on the lower die plate (12). The hot upsetting die seat is characterized in that the knock-out rod (1) is arranged in the die handle (2), a guide sleeve (6) is arranged in the upper fixed seat (5), and the upper safety nut (7) is in threaded connection with the upper fixed seat (5); the ejector sleeve (11) is arranged in the lower die plate (12), and an ejector rod (13) is arranged in the ejector sleeve (11); a lower cushion sleeve (14) is arranged on the upper side of the ejector sleeve (11), and a fixing sleeve (9) is arranged in the lower fixed seat (10); a die is arranged in each of the upper fixed seat (5) and the lower fixed seat (10). The hot upsetting die seat has high accuracy, and is simple, convenient, safe and practical.

Description

technical field [0001] The invention belongs to the technical field of die base components, and in particular relates to a hot heading die base for a press. Background technique [0002] At present, the deformation of the head of the fastener is generally divided into upper mold molding and lower mold molding according to the shape of the head and processing requirements. Different molding methods require different mold holders. If the molding method changes, the corresponding mold holders need to be replaced. , especially in the standard parts industry, the processed products are often changed and the mold base is often changed. Frequent replacement is not only a waste of time, but it is difficult to find the center of the upper and lower mold bases, which affects the concentricity of the product head and the rod. It is also very unsafe. The base weighs nearly 100 kg, and it is easy to hurt people when moving it up and down. Also, when adjusting the concentricity of the upp...

[0002] At present, the deformation of the head of the fastener is generally divided into upper mold molding and lower mold molding according to the shape of the head and processing requirements. Different molding methods require different mold holders. If the molding method changes, the corresponding mold holders need to be replaced. , especially in the standard parts industry, the processed products are often changed and the mold base is often changed. Frequent replacement is not only a waste of time, but it is difficult to find the center of the upper and lower mold bases, which affects the concentricity of the product head and the rod. It is also very unsafe. The base weighs nearly 100 catties, and it is easy to hurt people when moving it up and down. Also, when adjusting the concentricity of the upper and lower mold bases, if the control is not good, the upper and lower mold bases will collide, and it is easy to cause the jumping pieces to fly out and hurt people. cause safety accident
