Problems solved by technology

However, due to the different requirements for the weight error of single piece cutting and the different requirements for the flatness of the cut surface in the current production, the types and structures of the cutting dies make the types, structural functions and corresponding operation modes of the cutting dies quite different.

specific Embodiment approach

[0005] As shown in the figure, the round steel cutting die of the present invention includes two parts, an upper die and a lower die, and is suitable for a universal crank press. The unique working mechanism part of the mold includes an upper mold consisting of a cutting knife 5, a cutting knife pressing plate 7, a knife seat 8, a mold handle 9, etc., which are connected by screws 6 and 10 as shown in the figure to form a whole upper mold. Adjusting screw rod 1, locking nut 2, and adjusting seat 3 form the cutting length adjustment mechanism of the lower mold, which is connected with the lower mold seat plate 18 by the illustrated screw 21 and pin 22. The die 4 cooperates with the die support 12 through the opening clamping sleeve 11 in the radial direction, and is adjusted and tightened radially through the locking screw 19 and the locking nut 20 . The axial positioning of the die 4 is fixed by the axial sleeve 15 and the screw sleeve 13 and the die support 12 threaded pairs ...

Abstract

A die for cutting off round steel in a batch is mounted on a universal crank press to work. The die is provided with a blade for cutting off round steel, a round steel cutting length adjusting screw, an adjustable cavity for cutting off round steel and the like, the blade for cutting off round steel is fixed onto an upper die, the round steel cutting length adjusting screw is fixed to a lower die. The die is free of cutting waste, and working frequency of cutting-off production efficiency is identical to that of a press when the press is in a continuous running mode. The die for cutting off round steel is simple in structure, high in production stability and is implemented easily. Single-piece weight errors of cut steel bars in a batch are fewer, the flatness of cut surfaces meets production requirements, and the die for cutting off round steel is applicable to the first raw material cutting-off procedures of batch production of die forging, extrusion and the like, and also can be used for cutting off other round steel.

Description

technical field [0001] The invention relates to a mold for round steel cutting, which provides a mold required for the quick cutting process of round steel, which is installed on a universal crank press to work. The die is composed of a cutting blade fixed on the upper die, a round steel cutting length adjusting screw fixed on the lower die, and an adjustable round steel cutting die. The two ends of the steel bar cut by the die are basically flat, the weight error of a single piece is very small during mass production, and there is no cutting waste. The cutting efficiency is the same as that of the press in continuous operation mode, and the cutting efficiency is much higher than other mechanical cutting processes. This die cuts off the weight error of a single piece of steel rod and the flatness of the cut surface. It is suitable for the first raw material cutting process in mass production such as die forging and extrusion, and can also be used for cutting other round steel....
