Problems solved by technology

[0003] The existing rebar shearing device mainly has the following technical problems during use: one is that the waste produced in the rebar shearing is directly scattered on the ground of the construction site. It is not easy to clean, and kicking will cause foot injuries; second, the rebar needs to be manually arranged according to the grooves on the fixing device before cutting, so that it can be aligned with the grooves in the fixing device, but manual alignment is time-consuming It is long and inconvenient to use; the third is that the rebar is easy to bend under its own gravity during the feeding process, causing unsmooth feeding

Embodiment 1

[0042] Embodiment 1 has introduced a kind of finish-rolled rebar cold shear shearing device and shearing process, as Figure 1-3 As shown, it includes a base 1, an electric telescopic rod one 2, a support seat 3, an electric telescopic rod two 4, a shear knife 5 and a fixed arm 6, and the shearing device also includes a fixed foot 7, an auxiliary support assembly 8 and a rebar Storage component 9;

[0043] There is a pair of bases 1, and a support base 3 is fixedly connected to the central position of the upper surface of a pair of bases 1, and the shearing knife 5 is connected to a pair of support bases 3 in rotation, and the support base 3 Rotationally connected to the middle position of the shearing knife 5; one end of the shearing knife 5 is rotationally connected to the top of the electric telescopic rod-2, and the bottom end of the electric telescopic rod-2 is fixedly connected to the ground through a connecting plate and bolts On: the upper surface of the support base ...

Embodiment 2

[0054] Embodiment 2 is an improvement on the basis of Embodiment 1, as Figure 7-8 As shown, wherein, a pair of the bases 1 are equipped with a threaded steel storage assembly 9, and the threaded steel storage assembly 9 includes a collection slope 901 and a baffle 902, and the two sides of the collection slope 901 are respectively fixedly connected to On the side of a base 1; a pair of inner sides of the base 1 are provided with a vertical chute 903, and the chute 903 extends vertically downward from the upper surface of the base 1 to the collection swash plate 901. The two sides of the baffle plate 902 are respectively snapped into a chute 903 and the baffle plate 902 can slide freely in the vertical direction along the chute 903; The top surface of the baffle plate 902 is in close contact with;

[0055] In this embodiment, the present invention can collect the cut threaded steel waste by setting the collecting inclined plate and the baffle plate 902. The baffle plate 902 i...

Embodiment 3

[0062] Embodiment 3 is an improvement on the basis of Embodiment 2, as Figure 9-10 As shown, the lower surface of the limiting plate 1201 is fixedly connected with several limiting protruding blocks 17 , and each of the limiting protruding blocks 17 is located directly above a limiting groove 3 16 .

[0063] In this embodiment, the lower surface of the limiting plate 1201 is fixedly connected with a number of limiting protruding blocks 17 and the limiting protruding blocks 17 are in one-to-one correspondence with the limiting groove three 16. The threaded steel is fixed, so that the threaded steel is stably engaged in the third limiting groove 16.

Abstract

The invention provides a cold shearing device and process for finish-rolled deformed steel bars, and relates to the technical field of deformed steel bars. The cold shearing device comprises a base, a first electric telescopic rod, a supporting seat, a second electric telescopic rod, a shearing knife, a fixing arm, fixing feet, an auxiliary supporting assembly and a deformed steel bar storage assembly. According to the cold shearing device and process for the finish-rolled deformed steel bars, a first limiting groove is formed in the base, and the arrangement time of the deformed steel bars can be shortened; a lifting rod and a supporting roller are fixedly connected to the outer side of the base, the deformed steel bars entering a shearing area can be supported, and a sheared standby deformed steel bar section can be supported, so that the deformed steel bars are always kept in a horizontal state in the shearing process, manual supporting is not needed, and smooth feeding is ensured; and a limiting plate is arranged, so that the deformed steel bars can be prevented from falling off from the supporting roller. According to the cold shearing device and process for the finish-rolled deformed steel bars, a material collecting inclined plate and a baffle are arranged, so that cut deformed steel bar waste can be collected, the baffle is in sliding connection with the base, and the baffle can be conveniently disassembled.

Description

technical field [0001] The invention belongs to the technical field of threaded steel bars, in particular to a cold-shear shearing device and a shearing process for finished-rolled threaded steel bars. Background technique [0002] Rebar, also known as cold-rolled ribbed steel bar, refers to a steel material that forms a two-sided or three-sided crescent on the surface of the steel by a pair of rolls. The hardness of the rebar is high, and the rebar embedded in the concrete material has a great supporting force, so the rebar is widely used in construction. The rebar shearing device can cut the rebar installation target length, or remove the end of the rebar that does not meet the construction requirements. [0003] The existing rebar shearing device mainly has the following technical problems during use: one is that the waste produced in the rebar shearing is directly scattered on the ground of the construction site. It is not easy to clean, and kicking will cause foot inj...
