Abstract
The utility model discloses a material returning mechanism which is arranged on a cold-rolling mill. The cold-rolling mill comprises two hollow transverse cutting rolls which interact with each other, and the transverse cutting rolls are provided with protrusions and grooves at intervals along the circumstances of the transverse cutting rolls. The material returning mechanism comprises cams and material pushing rods, the cams are fixedly arranged along the axis of the transverse cutting rolls, a through hole is formed in the bottom of each groove in the transverse cutting rolls, the material pushing rods penetrate through the through holes and can perform reciprocating movement along the through holes under the effect of the cams, and the material pushing rods themselves further rotate along with the transverse cutting rolls around the axis. The material pushing rods are matched with the cams to be located in the grooves without extending out when the transverse cutting rolls cut. When the transverse cutting rolls continue to rotate, under the limit of the cams, the material pushing rods extend out of the bottoms of the grooves to eject a material.
Description
Technical field
The utility model relates to field of machining, specifically a kind of unloading mechanism.
Background technology
Soft metal particle cold-rolling mill is in when work, is to rely on the edge of a knife that protrudes between the cold-rolling mill upper cut roller and groove under the effect of rotary power, with the soft foil metal rollforming.Because the soft metal has adhesive, can be stuck in the groove after rolling and can't break away from.(such as Fig. 1).
The utility model content
Technical problem to be solved in the utility model provides a kind of unloading mechanism that is installed on the cold-rolling mill, can effectively material be deviate from from the groove of crosscut roller smoothly.
A kind of unloading mechanism described in the utility model, be installed on the cold-rolling mill, this cold-rolling mill comprises the crosscut roller of two interactions and hollow, the crosscut roller has projection and groove along the circle spacing, described unloading mechanism comprises cam, charging ram, and described cam is fixedly installed along the crosscut roll shaft heart, and the bottom of each groove is provided with through hole on the crosscut roller, charging ram passes through hole and can move back and forth along through hole under the effect of gravity and cam, and charging ram itself also rotates along the axle center with the crosscut roller.Charging ram cooperates with cam to be in the groove charging ram not stretch out when the crosscut roller cuts, after the crosscut roller was rotated further, under the restriction of cam, charging ram stretched out from bottom portion of groove material is ejected.
As improvement, an end of described material returned masthead material is provided with boss, and the other end that contacts with cam is for spherical.In order to prevent that the material returned bar from deviating from, the spheric end of material returned bar also is provided with pin
The utility model structure is simpler, does not need additionaling power, and easy to use and flexible has effectively guaranteed the normal operation of cold-rolling mill, and its normal operation cycle is prolonged greatly, has improved efficiency.
Description of drawings
Fig. 1 is the work schematic diagram of existing cold-rolling mill,
Fig. 2 is structural representation of the present utility model,
Fig. 3 is that Fig. 2 is left cutaway view.
The specific embodiment
As shown in Figures 2 and 3, the utility model is installed on the cold-rolling mill, and this cold-rolling mill basis is 1, two interaction of body, the 4 parallel installations of crosscut roller, crosscut roller 4 is by bearing 6 supportings, and driven by gear 5.Crosscut roller 4 hollows have projection and groove along the circle spacing.Unloading mechanism comprises cam 3 and charging ram 7, and cam 3 is fixedly installed along crosscut roller 4 axle center, and its two ends are fixed on the cam holder 2, and both also can make whole.The bottom of each groove is provided with through hole on the crosscut roller, and charging ram 7 passes through hole and can move back and forth along through hole under the effect of gravity and cam 3, and charging ram 7 itself also rotates along the axle center with the crosscut roller.One end of material returned masthead material is provided with boss, and the other end is spherical, and this spheric end is provided with the pin that prevents that charging ram from coming off.
The course of work: power passes to crosscut roller 4 by gear 5, and crosscut roller 4 rotates in the direction of arrows.Cam 3 maintains static, and material returned bar 7 is inserted on the crosscut roller and rotates with the crosscut roller.When material returned bar forwarded top to the crosscut roller, cam and material returned bar were disengaged positions, and under Action of Gravity Field, material returned masthead material end is fallen bottom portion of groove.When forwarding the operating position to, at this moment, the material 9 of sending into enters the crosscut roller by the top and is crosscut the roller cutting, has enough spaces to hold material in the crosscut roller groove.Along with the crosscut roller continues rotation, the working face that material returned bar spheric end touches cam gradually ejects gradually, and the material 8 of the well cutting in the groove is also deviate from groove thereupon gradually.When rotating to foot, under the effect of cam, material returned bar ejects groove fully, and material also just freely falls.Finish the material work of taking off.
The concrete application approach of the utility model is a lot; the above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
