Description

Technical Field

[0001] The present invention relates to the technical field of bar shearing equipment, and particularly to bar and wire fixed-length shearing equipment. Background Art

[0002] After the bar is rolled and cooled on the cooling bed, it needs to be cut to a fixed length. The fixed-length baffle of the metal bar plays a key role, especially as a key process device in the finishing area of steel bar manufacturing. It can standardize the fixed length of the bar to meet the specified requirements.

[0003] During shearing, the bar is conveyed along the transportation direction. The fixed-length baffle is set at a fixed position from the shearing point and is used to determine the length of the bar to be sheared. The fixed-length baffle blocks one end of the metal bar, and the shearing point starts shearing to obtain a bar with a fixed length.

[0004] The existing fixed-length baffle is sized by the push of a cylinder. When a cooled bar needs to be sheared, the fixed-length baffle needs to move back and forth under the action of a driving mechanism or a power mechanism, which increases mechanical wear, affects the sizing deviation and the mechanical service life. Moreover, the thrust of the bar conveyor roller path directly acts on the cylinder through the fixed-length baffle, making the cylinder easily damaged or generating large errors, affecting production and sizing accuracy.

Outside one of the positioning frames, there is a motor. The output end of the motor is connected to the cylinder through a coupling. On the outer surface of the cylinder, there are a plurality of positioning blocks evenly arranged along the circumferential direction. Each positioning block is provided with a positioning groove along the left-right direction. The opening of the positioning groove in the horizontal direction faces the transportation groove.

A plurality of positioning blocks 13 are evenly provided on the outer surface of the cylinder 11 along the circumferential direction. Each positioning block 13 is provided with a positioning groove 14 along the left-right direction. The opening of the positioning groove 14 in the horizontal direction faces the transportation groove 4. The length dimensions of each positioning groove 14 are different. Guide rollers 15 are evenly provided on the positioning groove 14; A controller 16 is provided outside the positioning frame 10. The controller 16 is connected to the motor 12.

[0022] A plurality of rows of fixed rods 17 are fixed to the upper surface of the base 1. The fixed rods 17 are located on the front and rear sides of the cylinder 11. The upper ends of the fixed rods 17 are rotatably connected to screening rods 18. A telescopic cylinder 19 is fixedly connected to the side wall of the fixed rod 17. The telescopic cylinder 19 is connected to the controller 16. The telescopic end of the telescopic cylinder 19 is connected to the rod wall of the screening rod 18;

[0023] Each positioning block 13 is provided with at least two screening grooves 20, and the screening grooves 20 are arranged along the circumferential direction of the cylinder 11. The screening rod 18 can rotate into the screening groove 20 and be tangent to the surface of the cylinder 11.

[0024] The lengths of the multiple fixed rods 17 arranged in the left - right direction are the same, and the lengths of the screening rods 18 rotatably connected to the upper ends are also the same; the lengths of the multiple fixed rods 17 arranged in the front - back direction are different, and the lengths of the screening rods 18 rotatably connected to the upper ends are also different.

[0025] The controller 16 is a PLC controller.

[0026] The number of the positioning grooves 14 is set according to the number of shear segments of the bar.

[0027] Among them, the transport rollers 5 and the guide rollers 15 are respectively connected with two drive motors, and these drive motors rotate or stop under the action of the controller 16; the motor 12 is a low - speed motor, which is convenient for classifying the bars after shearing; the motor 12 can also be set as a forward - reverse motor, which is convenient for changing the rotation direction of the cylinder 11, so as to change the bars that have been sheared into the front side or the rear side, improving the classification of bars with different lengths; and a chain, a collecting rod or a collecting plate can be arranged between the lower ends of two adjacent fixed rods 17 arranged in the front - back direction, which is convenient for transferring the bars that have been sheared.

[0028] Working principle: When in use, set the lengths of different positioning grooves 14 according to the length of the bar to be sheared, transport the cooled - down bar along the transport groove 4, and at the same time, under the rotation of the transport rollers 5, bring the bar into the positioning groove 14 and transport it above the upper end of the guide roller 15 in the positioning groove 14 until the bar reaches the bottom of the positioning groove 14, that is, the left - hand end of the positioning groove 14; at this time, use the controller 16 to start the hydraulic cylinder 7 to drive the cutter 9 to shear the bar, thus completing the shearing of the first - segment bar, and the unsheared bar is blocked by the cutter to prevent it from entering the positioning groove 14, or the rotation of the transport rollers 5 can also be stopped; among them, the motor 12 rotates at a certain time interval under the control of the controller 16, thereby driving the cylinder 11 to rotate, so that the positioning blocks 13 arranged on the cylinder 11 rotate, thus replacing another positioning groove to ensure that the other positioning groove is opposite to the transport groove 4; during the rotation of the cylinder 11, according to the length of the first - segment bar that has been sheared, control the telescopic cylinder 19 to expand and contract, thereby controlling the rotation of the screening rod 18 until the upper end of the screening rod 18 enters the inside of the screening groove 20 and is connected to the surface of the cylinder 11. During the rotation of the cylinder 11, under the action of the screening rod 18, the first - segment bar that has been sheared inside the positioning groove 14 is lifted, so that the bar falls to the preset position between the fixed rods 17, and for the bars that have not fallen, when the telescopic cylinder 19 resumes, it drives the screening rod 18 to lift and push up the bars that have not fallen, realizing classified collection.

[0029] At this time, the hydraulic cylinder 7 is used to drive the cutter 9 to move upward, or the driving motor is used to start the conveying roller 5, then the remaining uncut bars will continue to enter another positioning groove 14 arranged opposite to the conveying groove 4, and the above operations are repeated to achieve multiple fixed-length shearing of the bars until the shearing work of a section of bar is completed.
