Embodiment 1

[0038] Embodiment 1: a kind of round steel blanking method of improving efficiency comprises the following steps:

[0039]Step S1: measure, calculate the cut volume of the round steel according to the weight of the required blank, and then calculate the length of the blank after cutting according to the diameter of the round steel. The length of the blank conforms to the following formula: , where: L is the length of the blank after blanking; G is the weight of the blank, and its value is 1.10 to 1.15 times the weight of the finished workpiece; ρ is the density of the blank; R is the radius of the round steel.

[0040] From one end face of the round steel to the reference plane, a marking line is marked on the surface of the round steel along the axial length of the round steel. The length between adjacent marking lines is equal to L, and the marking line is the cutting position. Calculate the cutting length of the round steel according to the weight of the required billet, ...

Embodiment 2

[0046] Embodiment 2: a kind of blanking machine, as figure 1 As shown, a cutting device 100 and a delivery device 200 are included. The conveying device 200 is used for conveying the round steel to the cutting device 100, and the cutting device 100 exerts a shearing force on the round steel to realize blanking.

[0047] Such as figure 2 As shown, the cutting device 100 includes a frame 101, the frame 101 is fixedly connected with a first cutting block 102, and its horizontal side wall is provided with a semicircular feeding trough 103, and the feeding chute 103 and the transporting direction of the conveying device 200 set coaxially. A second cutting block 104 is horizontally slidably connected to the frame 101, and the sliding direction of the second cutting block 104 is perpendicular to the feeding direction of the conveying device 200. The sliding direction of the second cutting block 104 is close to the side wall of the feeding groove 103 . The side wall of the first ...

Abstract

The invention discloses a round steel blanking method for improving efficiency and a blanking machine using the same, and belongs to the field of forging blanking. According to the technical scheme, the round steel blanking method for improving efficiency is characterized by comprising the following steps that S1, measuring is conducted, and specifically, the size of round steel cut-off is calculated according to the weight of a required blank; step S2, heating is carried out, and specifically, round steel is heated; S3, cutting is conducted, and specifically, the round steel blanking machineis used for cutting the round steel, and the size of the blank after cutting is equal to the size calculated in the step S1; and S4, recrystallization heating is conducted, and specifically, the blankis conveyed into a heating furnace for heating. The method has the effect of reducing the damage of the blanking machine.

Description

technical field [0001] The invention relates to the technical field of forging blanking, more specifically, it relates to an efficient round steel blanking method and a blanking machine using the method. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging can eliminate defects such as as-cast porosity produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. For important parts with high loads and severe working conditions in related machinery, forgings are mostly used, except for plates, profiles or weldments that can be rolled with simpler shapes. [0003] Before forging, the billet needs to be cut from the r...
