The specific embodiment

Contrast accompanying drawing below,, the specific embodiment of the utility model is done further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.

Like the structure of the expressed the utility model of Fig. 1, Fig. 2, be a kind of buffer units of blooming mill manipulator guide and guard point, described guide and guard point 1 is fixedly mounted on the described manipulator 6 through steady pin 7.The utility model is a kind ofly to guarantee that guide and guard point 1 and manipulator 6 are on the same horizontal plane and the device of reducing friction; Specifically; Guide and guard point 1 is when swing; Can rapidly guide and guard point 1 be adjusted to same plane with manipulator 6, reduce the friction of guide and guard point safety pin 4 and pin-and-hole, thereby guarantee that steel billet passes in and out the device of groove accurately.

In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize improving the goal of the invention of the sharp security performance of guide and guard, the technical scheme that the utility model is taked is:

Like Fig. 1, shown in Figure 2, the buffer unit of this blooming mill manipulator guide and guard point that the utility model provides adds sheet metal 2 of weldering on described guide and guard point 1; On described guide and guard point 1, a spring 3 is set, an end of described spring 3 is fixed on the described guide and guard point 1, and the other end is fixed on the described manipulator 6.On original guide and guard point 1, install a spring 3 additional.

When rolled piece bumps against 1 last time of guide and guard points, spring 3 will be eliminated most power, and guide and guard point 1 then can reduce with the suffered power in manipulator 6 junctions greatly, thereby guide and guard point 1 abrasion deformation phenomenon is effectively improved.

When steel billet is helped the entering groove by guide and guard point 1; The steel material direction of motion is seen Fig. 1, and guide and guard point 1 receives the steel billet thrust, and guide and guard point 1 left and right directions has slight swing; Guide and guard point 1 swaying direction is also as shown in Figure 1; Then this moment, safety pin 4 was worn, but under the buffer protection function of sheet metal that adds weldering 2 and spring 3, and guide and guard point 1 can promptly be got back on the position with manipulator 6 same vertical planes; Guide and guard point 1 is exactly the plane of steel material direction with manipulator 6 same vertical planes, thereby has effectively reduced the wearing and tearing of safety pin 4.

The purpose of the utility model is in order to strengthen the fixing of guide and guard point 1, reduces the friction of guide and guard point safety pin 4 and pin-and-hole, guarantees the normal use of guide and guard point 1, thereby guarantees the accurate turnover blooming mill groove of steel material effectively.
