Description

Technical Field

[0001] The invention relates to the technical field of steel material processing, and more particularly to a furnace-exiting robot steel chisel straightening machine. Background Art

[0002] Against the background of widespread use of steel furnace tapping robots, a huge amount of special steel chisels are used for tapping robots. Due to the particularity of the usage scenarios and working methods, the deformed steel chisels cannot be reused after manual straightening, and there is no corresponding equipment on the market that can straighten them to the reuse standards, which brings great waste of materials to steel mills.

[0003] The present invention proposes a steel chisel straightening machine for a furnace-out robot, which solves the problems of steel chisel straightening, repairing and recycling of a steel-out robot for a steel-making furnace. Summary of the invention

[0004] In view of the above problems, the present invention intends to provide a steel bar straightening machine with a simple structure and obvious straightening effect, which can straighten the bent and deformed steel bar after use, solving the technical problem that manual straightening is impossible, and facilitating the repair and secondary use of the steel bar.

[0005] To this end, the present invention proposes a furnace robot steel bar straightening machine, comprising a feeding table, a straightening device and a material guiding table arranged in sequence. The steel bar enters the straightening device from the feeding table, is processed by the straightening device, and enters the material guiding table from the other side of the straightening device. If necessary, reverse secondary processing can be performed. The straightening device comprises a base, a frame, an active roller, a lower pressure roller, a lifting bracket and a motor; the base is used to support and fix the frame and the active roller, the active roller shaft is connected to the top of the base, at least two active rollers are provided, and both are connected to the motor; the two active rollers are arranged in a straight line along the feeding direction and have the same height, a lower pressure roller is provided above the middle position of every two adjacent active rollers, each of the lower pressure rollers is perpendicular to the feeding direction axis, and at least one lower pressure roller is arranged perpendicular to the horizontal plane, the lower pressure roller shaft is connected to the bottom of the lifting bracket, and the lifting bracket is slidably connected to the frame through the drive of the lifting mechanism; arc-shaped grooves are opened on the circumferences of the active roller and the lower pressure roller; the lower pressure roller and the active rollers located below the two sides of the lower pressure roller form a channel that can accommodate the steel bar passing through its groove, and form an upper and lower pressing force on the steel bar passing through the groove, so as to forcibly straighten the passing steel bar.

[0006] The above structure is intended to provide a straightening machine for a straightening steel chisel. The motor drives the active roller to rotate, and the steel chisel to be straightened is pulled into the straightening machine. The steel chisel passes through the groove channel formed by the lower pressure roller and the active roller, and moves forward along the straight channel. Under the action of the lower pressure roller and the active roller, the steel chisel is forcibly straightened.

[0007] Furthermore, when the number of the lower pressure rollers is greater than or equal to two, the angle between each two adjacent lower pressure rollers and the horizontal plane differs by 30° to 60°, preferably 45°; for example, when the number of the lower pressure rollers is three, the number of active rollers is four, and the four active rollers are all arranged vertically upward, while the three lower pressure rollers are fan-shaped around the central axis in the feed direction, with the first lower pressure roller arranged vertically downward, the second lower pressure roller being located on the left side of the first lower pressure roller, inclined at 45° to the lower right, and the third lower pressure roller being located on the right side of the first lower pressure roller, inclined at 45° to the lower left; thereby forming a structure that presses against the central axis from different directions, which has a more precise and efficient straightening effect.

[0008] Furthermore, it also includes a roller bracket, the active roller shaft is connected to the roller bracket, and the roller bracket is detachably fixed to the base; the lower pressure roller shaft is connected to the roller bracket, and the roller bracket is detachably fixed to the bottom of the lifting bracket; by adding the roller bracket, the active roller and the driven roller are detachably connected to the base and the lifting bracket respectively, so that the equipment can be used for straightening steel bars of different strengths and different outer diameters. The distance between each straightening roller (active roller, lower pressure roller) can be adjusted, and the straightening rollers (active roller, lower pressure roller) with different inner diameter grooves can also be replaced.

[0009] Furthermore, the lifting mechanism is a downward pressure cylinder and a hydraulic system, and the downward pressure cylinder is connected to the hydraulic system through a pipeline.

[0010] Furthermore, the motor is a bidirectional stepping motor, which can run in the forward direction and can also run in the reverse direction, and can perform secondary reverse straightening on the steel drill with unsatisfactory straightening effect.

[0011] Furthermore, a material guide roller is provided on the material guide platform, and an arc-shaped groove is provided on the circumference of the material guide roller;

[0012] Furthermore, universal casters are provided at the bottom of the material guiding platform.

[0013] Furthermore, it also includes a numerical control unit, which is electrically connected to the motor and the downward pressure cylinder.

[0014] Compared with the prior art, the overall technical effect of the present invention is:

[0015] The steel bar straightening machine of the present invention uses the central groove formed by each straightening roller (active roller, lower pressure roller) as the central axis to forcibly straighten the steel bar so that it meets the standard for reuse; at the same time, the position of each straightening roller is adjustable and replaceable, and can be suitable for the processing of steel bars with different diameters; thirdly, multiple lower pressure rollers set at different lower pressure angles can straighten the steel bar from several key directions, and the straightening effect is more obvious.
