Description

Reinforcing steel bar straightening and cutting equipment and method

Technical Field

The invention relates to the technical field of cold rolling equipment and steel bar processing, in particular to steel bar straightening and cutting equipment and method.

Background

On the steel bar production line, for fixed length shearing of the steel bars, a fly shearing breaking mode is often adopted. When the flying shears are used for shearing the steel bars, the speed measuring wheel is utilized to rotate along with the steel bars and send counting pulses, when the pulse number reaches the set pulse number, the length of the steel bars meets the set length, the turntable is started to rotate for one circle, and when the shearing blades of the flying shears reach the positions of the steel bars, the linear speed of the shearing blades is consistent with the running speed of the steel bars, so that the fixed-length shearing of the steel bars is realized.

In the shearing process of the flying shears, inertia needs to be overcome when the turntable is started, and the linear speed of the shearing blade is difficult to reach the speed synchronous with the steel bars in a short time; and after the shearing blade cuts the reinforcing steel bar, the turntable needs to be quickly stopped at a fixed position, so that the turntable is difficult to quickly stop because of rotational inertia. Therefore, the flying shear structure is only suitable for a production line with low processing speed of the steel bars and has low production efficiency. If the flying shear turntable continuously operates for shearing, the linear speed of the shearing blade is consistent with the operation speed of the steel bars, so that only the steel bars with unique lengths can be cut off, the steel bars cannot be sheared according to the required fixed length, and the production efficiency is affected.

After the flying shear mechanism is used for a long time, gaps exist due to abrasion of the mounting gears of the flying shears, and the gaps of the gears are difficult to adjust, so that the shearing length and the quality of the cuts can be affected.

Optionally, the reinforcing steel bar straightening and cutting apparatus further comprises a counting mechanism 5, wherein the counting mechanism 5 is arranged between the traction mechanism 2 and the feeding assembly 3 to count the conveying length of the reinforcing steel bar 100, and the counting mechanism 5 is in communication connection with the first driving mechanism 33.

As shown in fig. 1, the counting mechanism 5 measures and counts the length of the reinforcing steel bar 100 entering the feeding assembly 3, and when the conveying length is equal to the designated length, the first driving mechanism 33 drives the supporting member 32 of the feeding assembly 3 to rotate or move from the removing position to the cutting position according to the measurement and counting result, and the cutting mechanism 4 performs one cutting action on the reinforcing steel bar 100. It can be understood that the first driving mechanism 33 performs the position switching control of the reinforcing bars 100 according to the measurement count provided by the counting mechanism 5, so as to obtain the reinforcing bars 100 with changed length under the working condition that the cutting blade 42 continuously rotates, realize cutting the reinforcing bars 100 with variable length without stopping the machine, improve the cutting efficiency of the reinforcing bars 100, and improve the cutting control precision. The counting mechanism 5 and the first driving mechanism 33 may be electrically connected to the control mechanism at the same time and in communication with the control mechanism to realize mutual communication control.

It should be noted that, the reinforcing steel bar straightening and cutting device in this embodiment further includes a paying-off mechanism 6, a discharging mechanism 7 and a control mechanism, where the paying-off mechanism 6, the traction mechanism 2, the straightening mechanism 4, the counting mechanism 5 and the discharging mechanism 7 are all electrically connected and communicatively connected with the control mechanism to realize automatic control and realize start-stop coordination of the mechanisms. The paying-off mechanism 6 is wound and stored with the steel bar 100 to be cut off, is arranged at the upstream of the traction mechanism 2, and the steel bar 100 is gradually paid out through the paying-off mechanism 6 and conveyed under the traction action of the traction mechanism 2. The unloading mechanism 7 is arranged in front of the cutting mechanism 4 and is used for temporarily storing the cut fixed-length reinforcing steel bars 100 so as to be stored in a centralized manner and used for subsequent processing. In one embodiment, the unloading mechanism 7 may be configured to temporarily store the cut reinforcing bars 100 by using an unloading frame structure, and other specific configurations are not limited.

Under the condition that the unfolding description is not performed, the steel bar straightening and cutting equipment provided by the embodiment adopts the conventional arrangement in the field, for example, the traction mechanism 2 is required to be arranged conventionally in the prior art to realize the function of conveying the steel bars 100, and the embodiment of the specific structure is not limited.

s1, pulling the reinforcing steel bar 100 forwards from the paying-off mechanism 6, sequentially passing through the traction mechanism 1, the straightening mechanism 2 and the support 32, and partially exposing the front end of the support 32; setting the linear speed of the cutting knife 42 to be equal to or higher than the conveying speed of the reinforcing steel bar 100; the cutting mechanism is started to enable the flying shear disc 41 to drive the cutting knife 42 to rotate continuously;

s2, the support 32 rotates to enable the steel bar 100 at the front end to be in a moving-out position;

s3, continuously conveying the reinforcing steel bars 100 by the paying-off mechanism 6 and the traction mechanism 1, straightening the reinforcing steel bars 100 by the straightening mechanism 2, and then entering the supporting piece 32;

s4, controlling the support 32 to rotate and drive the steel bar 100 to switch to a cutting position according to the cutting length of the steel bar 100, and cutting the steel bar 100 by the cutting knife 42;

s5, returning to the step S2 until the required number of reinforcing bars 100 with cut lengths are obtained.

Preferably, the second driving mechanism 44 is arranged to make the linear speed of the cutting knife 42 equal to the linear speed of the traction mechanism 1 for conveying the reinforcing steel bar 100, so that the cutting knife 42 and the reinforcing steel bar 100 can be synchronous during cutting, and the accuracy of the shearing length can be ensured. The cutting position corresponds to the shearing position of the cutting knife 42, the moving-out position is an idle position which is opposite to the cutting position and avoids the interference between the conveyed reinforcing steel bar 100 and the cutting mechanism 4, when the cutting knife 42 is in the moving-out position, the reinforcing steel bar 100 is continuously rotated, when the counting mechanism 5 prompts that the length of the reinforcing steel bar meets the requirement, the first driving mechanism 33 drives the reinforcing steel bar 100 to return to the cutting position, and the cutting knife 42 executes one shearing. The above process needs to be uniformly controlled by the control mechanism so as to obtain an accurate shearing length, and on the premise that the linear speed of the cutting knife 42 is greater than the conveying speed of the reinforcing steel bar 100, the length of the reinforcing steel bar 100 can be adjusted by controlling the first driving mechanism 33 to drive the bearing member 32 to rotate or move in the horizontal plane, so that flexible shearing is realized.
