Description

Technical Field

[0001] The utility model belongs to steel billet processing equipment, in particular to a steel billet hot shearing device. Background Art

[0002] In order to avoid the burr phenomenon of cold shearing, the hot shearing process is usually adopted for the shearing of steel billets, that is, the steel billets are first heated to a temperature suitable for shearing, and then sent to the shearing machine for shearing. At present, when the steel billets are cut off, the residual amount of the steel billets to be removed should be as little as possible. Therefore, the size requirements are usually different from those when the steel billets are sheared into sections. This makes the positions of the positioning parts different when performing these two operations. Because of this, the current production line usually needs to be equipped with two shearing devices. After the steel billets are cut off, they continue to move forward and are cut into sections by another shearing device. This will undoubtedly extend the length of the production line and increase energy consumption costs. Utility Model Content

[0049] The use of the utility model:

[0050] Preparation: Turn the adjusting screw 10 to slide the slider 9 to a suitable position;

[0051] The head pinching operation of the head end steel billet 31 is performed: first, the equilateral triangle positioning seat 5 is rotated to turn the thick positioning protrusion 6 to the position corresponding to the steel billet accommodating area, and then, the hot steel billet 31 is sent to the steel billet accommodating area 29 between the upper blade table 14 and the lower blade table 16 via the conveyor roller 2, and abuts against the thick positioning protrusion 6. At this time, the shearing motor 24 is started, and the upper blade table 14 and the counterweight pressing block 19 are pressed down together, so that the upper cutting knife and the counterweight pressing block 19 abut against the steel billet 31. At this time, the steel billet 31 has been pressed tightly, and the positioning piece 4 is no longer needed for positioning. At this time, if the equilateral triangle positioning seat is located below the upper blade table 14, the equilateral triangle needs to be rotated counterclockwise. The positioning seat 5 is arranged such that the side of the regular triangle positioning seat 5 without the positioning protrusion corresponds to the steel billet 31, and the pressing channel of the upper blade table 14 is cleared, and then the steel billet 31 is continuously pressed down and cut. If the thick positioning protrusion 6 is located on one side of the upper blade table 14 at this time, there is no need to rotate the positioning piece, and the upper cutter can be directly pressed down to cut the steel billet 31. At this time, the counterweight pressing block 19 no longer moves downward, and the inverted U-shaped hanging rod continues to move downward with the upper blade table 14 and is placed on both sides of the lower blade table. After the steel billet 31 is cut, the shearing motor 24 continues to rotate, the upper blade table 14 moves upward, and the inverted U-shaped hanging rod drives the counterweight pressing block 19 to reset. After the shearing motor 24 completes one circle of rotation, it stops.

[0052] The billet 31 is cut into sections: the regular triangle positioning seat 5 is rotated to make the thin positioning protrusion 7 correspond to the position of the billet accommodating area 29, and the billet 31 conveying device is started to make the billet 31 continue to move forward until it abuts against the thin positioning protrusion 7, and then the shearing motor is started to rotate, and the upper blade table 14 and the counterweight pressing block 19 are pressed down together, and the billet 31 is cut off. At this time, the counterweight pressing block 19 no longer moves downward, and the inverted U-shaped hanging rod continues to move down with the upper blade table 14. After the billet 31 is cut off, the shearing motor 24 continues to rotate, the upper blade table 14 moves up, and the inverted U-shaped hanging rod drives the counterweight pressing block 19 to reset. After the shearing motor 24 completes one circle of rotation, it stops; then the billet 31 conveying device is started to make the billet 31 continue to move forward until it abuts against the thin positioning protrusion 7, and the next segmentation operation is started, until only the tail end residual material is left, and the rear shearing motor 24 stops;

[0053] Pushing material: Start the hydraulic push rod 28 to push the tail end residual material out of the lower blade table 16.

[0054] The utility model improves the positioning member 4, sets the positioning member 4 into a rotatable equilateral triangle positioning seat 5, and sets two positioning protrusions with different thicknesses on the side wall of the equilateral triangle positioning seat 5, and leaves one side without a positioning protrusion, so that the position of the positioning member 4 can be adjusted by rotating the equilateral triangle positioning seat 5, thereby realizing the positioning of the billet 31 during the cutting process.

[0055] Because, on the current production line, when cutting off the head and tail of the steel billet 31, after the head end residue is sheared off, the steel billet 31 needs to move forward to shear the tail residue, so that Figure 1 As shown, the positioning member 4 needs to swing back and forth to complete the size positioning and make way for the billet channel. In order to ensure the stability of shearing, the upper blade platform 14 for hot shearing of the billet 31 is usually set wider, and the swinging setting method requires a larger swinging space. Due to space limitations, the positioning member 4 cannot be set below the upper blade platform 14, but can only be set on one side of the upper blade platform 14 for limiting, which undoubtedly increases the width of the head end residual material and leads to a waste of raw materials. The utility model can also place the thick positioning protrusion 6 below the lower blade platform 16 to position the billet 31. When positioning in this way, it is only necessary to rotate the equilateral triangle positioning seat 5 in time when the lower blade platform 16 and the counterweight pressure block 19 contact the billet 31, and move the thick positioning protrusion 6 out from under the lower blade platform 16 to make way for the upper blade platform downward pressure channel. This structure can greatly shorten the width of the head end residual material and save the billet 31 raw materials.

[0056] The above-mentioned embodiments are only preferred embodiments of the present invention, and are not exhaustive of the feasible implementations of the present invention. For those skilled in the art, any obvious changes made to the present invention without departing from the principle and spirit of the present invention should be considered to be included in the scope of protection of the claims of the present invention.
