Description
Technical Field
The utility model relates to a hot rolling belted steel limit portion burring device belongs to metallurgical industry hot rolling belted steel production facility technical field.
Background
The hot rolled strip steel after pickling needs to be subjected to edge cutting to meet the requirement of a user on special width, and the pickling line adopts more edge cutting devices as disc shears, but fine burrs are easily generated on the edge of the thin strip steel after edge cutting of the disc shears, so that the appearance of a product is influenced, and the subsequent use of the strip steel is influenced. At the moment, a deburring device is required to be added after trimming to trim the burrs at the edge of the trimmed strip steel.
At present, a pair of flat rollers which are arranged in parallel up and down are mostly adopted in a deburring device used in a production line, as shown in figure 1, the flat rollers have the advantages that the flat rollers are in plane contact with strip steel, the production process is not limited by plate shapes, the flat rollers can be effectively in contact with the strip steel to remove burrs remained on the edge of the strip steel, but the plane contact is in a high-speed running state, a large amount of heat is generated along with the deburring of the deburring rollers, so that a connecting bearing is easy to damage and clamp, and meanwhile, the steel rollers are in contact with the surface of the strip steel, scrap iron is brought in, and the hidden danger of indentation is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hot rolling belted steel limit portion burring device can effectively get rid of side cut back belted steel limit portion burr under the condition that does not receive the plate-type influence, avoids producing additional defect simultaneously, solves the problem that exists among the background art.
The technical scheme of the utility model is that:
the utility model provides a hot rolling belted steel limit portion burring device, sets up in the both sides of belted steel, contains deburring roller, shaft hole, cylinder, bearing frame, bearing and frame, deburring roller contains parallel arrangement's last roller and lower roll, and the roll surface of deburring roller is oval, and middle diameter is greater than the diameter at both ends, and deburring roller has the shaft hole, is equipped with the roller shaft in the shaft hole, and the roller shaft is equipped with bearing and bearing frame, and the lower roll of deburring roller is fixed in the frame, and the last roller of deburring roller is connected with the piston rod of cylinder, and the cylinder body of cylinder is fixed in the frame.
And a connecting rod is fixed on an upper roller bearing seat of the deburring roller and is hinged on the rack.
And a lower roll bearing seat of the deburring roll is fixed on the machine frame.
And the upper roller and the lower roller of the deburring roller are respectively positioned on the upper side and the lower side of the strip steel.
The utility model has the advantages that: the deburring roller with the oval roller shape has high eccentricity, and when burrs on the edge of strip steel are removed, the deburring roller is in close line contact with the edge of the strip steel, the contact mode can play a certain auxiliary clamping and conveying effect under the condition of poor plate shape and the same image surface contact, the problem of poor quality of edge burr removal caused by edge jumping is solved, the damage of a large amount of heat generated in the production process to a bearing due to the fact that the whole roller surface contacts the strip steel can be avoided, and the hidden danger of indentation defects caused by the fact that scrap iron is brought in is avoided.

Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to the attached drawings 2 and 3, the deburring device for the edge of the hot-rolled strip steel is arranged on two sides of the strip steel and comprises a deburring roller 1, a shaft hole 5, a cylinder 6, a bearing seat 7, a bearing 8 and a rack 9, wherein the deburring roller 1 comprises upper rollers and lower rollers which are arranged in parallel, the roller surface of the deburring roller 1 is oval, the diameter of the middle of the deburring roller is larger than the diameters of two ends of the deburring roller 1, the deburring roller 1 is provided with the shaft hole 5, a roller shaft is arranged in the shaft hole 5 and is provided with the bearing and the bearing seat, the lower roller of the deburring roller 1 is fixed on the rack 9, the upper roller of the deburring roller 1 is connected with a piston rod of the cylinder 6, and a cylinder body.
In the present embodiment, the axial cross section of the deburring roller 1 is an elliptical surface with both side end surfaces being substantially rectangular, and the shaft body is provided with a shaft hole in a hollow manner, as shown in fig. 2.
Referring to the attached figure 3, an arrow P is the running direction of the strip steel, the deburring roller 1 is assembled on a bearing seat 7 through a bearing 8, the bearing seats 7 of the upper roller and the lower roller are respectively fixed on a rack 9 and a piston rod of a cylinder 6, and a connecting rod is fixed on the bearing seat of the upper roller of the deburring roller 1 and is hinged on the rack 9. In the non-operating state, the air cylinder 6 opens the upper roller of the deburring roller 1, so that the racks 9 on the two sides of the strip steel are in the off-line position; when the device works, the distance between the upper roller and the lower roller of the deburring roller 1 on two sides is adjusted through the air cylinder 6, so that the two rollers are closed, the longitudinal axis presses the edge of the strip steel, and the burrs on the edge of the strip steel are removed.
When the burrs at the edge of the strip steel are removed by adopting the oval roller surface, the contact mode of the oval roller surface and the strip steel is line contact, a large amount of heat generated by friction in the working process is avoided, meanwhile, the roller surface adopts larger eccentricity, an auxiliary clamping and conveying effect is realized in the strip steel threading and tail flicking process, and the bad phenomenon of burr removal caused by the condition of insufficient jumping tension at the edge with poor plate shape is avoided.
