The technical field is as follows:

the invention relates to the technical field of steel rolling auxiliary equipment, in particular to a blanking buffering device of a billet feeding rack.

Background art:

in the prior art, a steel slab is usually loaded into a heating furnace and heated to a suitable temperature before hot rolling, and then rolled. Before the steel billet is loaded into the heating furnace, the steel billet is generally required to be hoisted onto a feeding rack through a crown block, the feeding rack moves in a stepping mode to drive the steel billet to move forwards, then the steel billet falls onto a receiving device, the receiving device moves in a lifting mode to lift to a high position to receive the steel billet falling from the parabola motion, then the steel billet falls onto a low position to place the steel billet on a furnace roller way, and the steel billet is conveyed into the heating furnace through the roller way. When the billet falls onto the material receiver, the billet has larger momentum due to parabolic motion, and the instant impact on the material receiver is very large when the billet is knocked to the material receiver, so that the material receiver is easy to damage, and the billet is also easy to bend and generate mechanical damage.

The invention content is as follows:

the blanking buffer device of the billet feeding rack aims to overcome the defects of the prior art, and provides the blanking buffer device of the billet feeding rack, which can buffer the impact of billets on a receiver, prolong the service life of the receiver, solve the problems of impact bending and mechanical damage of the billets, and has the advantages of simple equipment structure, convenient operation and obvious effect.

The technical scheme provided by the invention for solving the problems is as follows: a blanking buffering device of a billet feeding rack comprises a receiving platform, a baffle plate, a rib plate, an inner sleeve, an outer sleeve, a limiting cover, a base, a spring and a billet; the material receiving platform is arranged above the spring; the spring is arranged above the base and inside the inner sleeve and the outer sleeve; the baffle is vertically and fixedly connected to the horizontal table surface of the material receiving table; the baffle plate is fixedly connected with the material receiving platform through a rib plate; the inner sleeve is fixedly connected below the material receiving platform; the outer sleeve fixedly connected outside the inner sleeve is fixedly connected to the base; the limiting cover is connected to the top end of the outer sleeve; a spring is arranged between the inner sleeve and the base; the bottom end of the inner sleeve is provided with an anti-release buckle which is matched with the limit cover for limiting connection.

In the blanking buffer device of the billet feeding rack, the baffle is welded with the receiving platform and the rib plate;

in the blanking buffer device for the billet feeding rack, the outer sleeve fixedly connected outside the inner sleeve is welded on the base.

The invention has the beneficial effects that: the energy of the billet hitting the material receiving platform can be effectively absorbed, the service life of the material receiving device is prolonged, the billet is prevented from being bent and mechanically damaged, and the horizontal displacement of the billet is effectively blocked. The device has simple structure, convenient operation, obvious effect, safety and reliability.

Description of the drawings:

fig. 1 is a schematic structural diagram of an embodiment of the present invention.

In the drawings: 1. a receiving platform; 2. a baffle plate; 3. a stiffening plate; 4. an inner sleeve; 5. an outer sleeve; 6. a limiting cover; 7. a base; 8. a spring; 9. and (3) steel billets.

The specific implementation mode is as follows:

the invention is described in further detail below with reference to the figures and examples. A blanking buffering device of a billet feeding rack is shown in figure 1: comprises a receiving platform 1, a baffle 2, a stiffening plate 3, an inner sleeve 4, an outer sleeve 5, a limiting cover 6, a base 7, a spring 8 and a billet 9. The receiving platform 1 is arranged above the spring 8; the spring 8 is arranged above the base 7 and inside the inner sleeve 4 and the outer sleeve 5; the baffle 2 is vertically and fixedly connected to the horizontal table surface of the receiving table 1; the baffle 2 is welded with the material receiving platform 1 through a rib plate 3; the inner sleeve 4 is fixedly connected below the material receiving platform 1; the outer sleeve 5 fixedly connected with the outer surface of the inner sleeve 4 is welded on the base 7; the limiting cover 6 is connected to the top end of the outer sleeve 5; a spring is arranged between the inner sleeve 4 and the base 7; the bottom end of the inner sleeve 4 is provided with an anti-release buckle which is mutually matched and limited with the limit cover 6. The working principle of the invention is as follows: connect material platform 1 to be located the device top, baffle 2 perpendicular to connect material platform 1 horizontal plane, baffle 2 and connect and expect through gusset 3 fixed between the platform 1, prevent to connect the angle between platform 1 and the baffle 2 to be strikeed by the steel billet and change. The inner sleeve 4 is located below the receiving table 1, inside the outer sleeve 5. The outer sleeve 5 is located on a horizontal base 7. The limit cap 6 is positioned at the top end of the outer sleeve 5. A spring 8 is arranged between the inner sleeve 4 and the base 7. After the spring 8, the inner sleeve 4 and the outer sleeve 5 are assembled, the limiting cover 6 is additionally arranged at the upper end of the outer sleeve 5, the bottom end of the inner sleeve 4 is provided with a disengagement-preventing buckle, the limiting cover 6 and the limiting cover 6 mutually play a limiting role, and the spring 8 can be prevented from popping the inner sleeve 4 upwards out of the outer sleeve 5. When the descending distance of the material receiving platform 1 is too large, the limiting cover 6 can support the material receiving platform 1, the inner sleeve 4 is prevented from moving downwards too much, and the tail end of the inner sleeve 4 is prevented from being separated from the buckle and colliding and deforming with the base 7. The steel billet 9 does parabolic motion in the falling process, the baffle 2 prevents the horizontal displacement of the steel billet 9 at the moment of hitting the receiving platform 1 at the vertical speed and the horizontal speed, and the inner sleeve 4 and the outer sleeve 5 are matched to rapidly absorb the falling momentum of the steel billet 9 and effectively eliminate the falling horizontal speed of the steel billet 9.
