Detailed Description
The invention will be further described with reference to specific embodiments and drawings.
Examples
The utility model provides a novel cold shears sweeps tail device for in the cold shears production line of steel, arrange before the upper and lower cutting edge of cold shears, after accomplishing steel shearing, get rid of remaining steel tails on the platen through the upset platen, carry out detailed description to its specific structure and theory of operation below.
As shown in fig. 1 to 3, the tail sweeping device of the cold shears mainly comprises a base 1 serving as a mounting base, a bedplate 2 for receiving steel materials, a driving cylinder 3 for controlling the bedplate 2 to turn, a front rocker 4 and a rear rocker 5. Wherein, the driving cylinder 3, the front rocker 4 and the rear rocker 5 are all hinged with the bedplate 2 at one end and hinged with the base 1 at the other end.
Specifically, in order to provide a relatively convenient installation space for the driving cylinder 3, the front rocker 4 and the rear rocker 5, a pair of supporting seats 11 are symmetrically arranged on two sides of the base 1 along the feeding direction, and the lower end face of the bedplate 2 is provided with the overturning bracket 6. The support 11 includes setting up a pair of fixed plate on base 1 side by side, is equipped with the pivot of a perpendicular to cold shears pay-off direction between the front end of a pair of fixed plate and between the rear end respectively, and the one end of preceding rocker 4 is connected with the pivot that is located the support 11 front end is articulated, and the other end is connected with the front end of upset support 6 is articulated, and the one end of back rocker 5 then is connected with the pivot that is located the support 11 rear end is articulated, and the other end is connected with the rear end of upset support 6 is articulated. The mode that the rotating shaft is hinged is arranged at the hinge point of the front rocker and the rear rocker and the base 1, so that the overturning and translating direction of the bedplate 2 can be parallel and level to the feeding direction of the cold shearing machine, and the overturning track of the bedplate 2 can be accurately and conveniently controlled. The driving cylinder 3 adopts an oil cylinder, the middle part of the bottom of the base 1 is provided with a hinged seat 8, one end of the driving cylinder 3 is hinged with the hinged seat 8, and the other end is hinged with the overturning bracket 6.
In this embodiment, in order to further ensure the accuracy of the turning track of the bedplate 2, the front and rear rocking bars are hinged to the turning support 6, and the driving cylinder 3 is hinged to the turning support 6 through a rotating shaft, which is basically the same as the connection between the front and rear rocking bars and the support 11. In addition, the hinge points of the front rocker 4 and the rear rocker 5 with the support 11 are positioned at the upper part of the support 11 and are positioned at the same height, and the hinge point of the driving cylinder 3 with the bedplate 2 is positioned at the center of the connecting line of the two hinge points of the two rear rockers 5 with the bedplate 2. The length of the rocker can be saved by arranging the hinge points of the front rocker 4 and the rear rocker 5 with the support 11 on the upper part of the support, the cost is saved, and the overlong rocker is easy to damage and collide. The hinged points of the front rocker 4, the rear rocker 5 and the support 11 are located at the same height, which is mainly used for keeping the hinged points parallel to the initial state of the turning support 6, so that a four-bar mechanism consisting of the turning support 6, the front rocker, the rear rocker and the base 1 can run along a specific turning track to avoid other components of the cold shears. And the pin joint of the driving cylinder 3 and the bedplate 2 is positioned at the center of the connecting line of the two pin joints of the two back rocking bars 5 and the bedplate 2, so that the driving cylinder 3 mainly rotates by controlling the back rocking bar 5, the back rocking bar 5 drives the front rocking bar 4 to rotate, the bedplate 2 can be controlled to retreat at a smaller overturning speed and a larger horizontal speed when just starting to overturn, steel is driven to rapidly separate from a shearing edge area, and jamming and abrasion caused by collision with the shearing edge area, steel pressing mechanisms above the bedplate 2 and other components are avoided.
Therefore, the driving cylinder 3 arranged below the bedplate 2 controls the bedplate 2 to overturn and remove materials, and the problem that the conventional tail sweeping device is difficult to install and arrange in a cold shearing production line with compact arrangement space is effectively solved. And the arrangement of the four-bar linkage mechanism enables the bedplate 2 to be moved out of the shearing edge area in the horizontal direction, and then a larger overturning speed is generated to enable the tailings to slide off the bedplate 2, so that the tailings on the bedplate 2 can avoid other components such as upper and lower shearing edges, a steel pressing mechanism and the like, the tail end is lifted up when the bedplate 2 is overturned and cannot be blocked by corresponding components above the bedplate 2, and the cold shearing production line is very suitable for a cold shearing production line with compact arrangement space.
However, when the platen 2 is just turned over, since the platen 2 is retreated at a large horizontal speed, the tailings on the platen 2 will be displaced a distance toward the lower cutting edge by the relative movement, and contact with the surface of the lower cutting edge and cause abrasion, which reduces the service life of the lower cutting edge. The inventors have tried to avoid this problem by adjusting the flip trajectory of the platen 2, but the results are not particularly desirable. Therefore, the present embodiment takes the following measures.
The turnover support 6 is arranged on the lower end face of the bedplate 2, one end of the turnover support is hinged with one end of the bedplate 2, which is far away from the shear blade, and the other end of the turnover support is connected with one end of the bedplate 2, which is close to the shear blade, through a spring 7 in a supporting manner. When the steel material is sheared, the steel pressing mechanism presses the steel material on the surface of the bedplate 2 and compresses the spring 7, so that the bedplate 2 is kept in a horizontal state with the same height as the lower shearing blade. When getting rid of the tails, the pressure steel mechanism rises, and spring 7 extension is with certain height of platen 2 jack-up, makes the tails on the platen 2 break away from with the contact on lower shear blade surface to avoid when carrying out translation and upset to platen 2, the tails can take place wearing and tearing each other with lower shear blade when displacement one end distance down earlier under relative motion's principle, improve shear blade's life down, especially to the comparatively serious panel tails of friction, the effect of this measure is extremely obvious. In order to ensure the balance stability when the springs 7 jack the bedplate 2, the springs 7 are provided with a plurality of 6 springs which are arranged at equal intervals perpendicular to the feeding direction of the cold shearing machine.
It should be mentioned that, in this embodiment, a limiting plate 12 is installed at the rear end of the upper portion of the support 11, a position sensor 9 is installed on the limiting plate 12, and an induction area matched with the position sensor 9 is installed on the rear rocker 5. The position sensor 9 can respectively detect the positions of the rear rocker 5 when the bedplate 2 is in the initial state and the overturning finished state and generate sensing signals, and controls the work of the driving cylinder according to the sensing signals, so that the position accuracy of the overturning and the recovering of the bedplate 2 in the initial state is improved, and the control is more accurate and convenient.
In conclusion, the tail device is swept to novel cold shears of this embodiment can be applied to the cold shears production line that arranges the space compactness, improves the efficiency of getting rid of the cold shears tails, and because it adopts the upset to go the mode of material and four-bar linkage common work for it still has better effect to longer tails.
