Technical field

The utility model relates to the cold rolling processing equipment of a kind of metal, relates in particular to a kind of round end rolling mill.

Background technology

At present, the roll that is used to process the round end rolling mill of anchor pole is the circumference formula, and roll is reciprocating type rotation during machine works, and roll need rotate four, five times repeatedly during rolling anchor pole, causes machine short service life, and production efficiency is low.

Summary of the invention

The purpose of this utility model provides a kind of long service life, round end rolling mill that production efficiency is high.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of round end rolling mill, comprise base, frame is installed on the base, be rotatably installed with topping roll and bottom roll on the frame relatively, topping roll is corresponding up and down with bottom roll, all has rolling ditch on topping roll and the bottom roll, it is characterized in that: have breach on the topping roll, have down breach on the bottom roll, last breach is corresponding up and down with following breach; Be fixedly connected with material guide port on the frame, material guide port is corresponding with the slit between topping roll and the bottom roll.

According to described round end rolling mill, it is characterized in that: be fixedly connected with the regulating block supporting plate on the described frame, it is female to be fixedly connected with the length back of the body on the regulating block supporting plate, length is carried on the back female internal thread and is connected with the length adjustment leading screw, one end of length adjustment leading screw is fixedly connected with the length adjustment handwheel, the other end of length adjustment leading screw is connected with the length adjustment piece, and the length adjustment piece is corresponding with material guide port.

According to described round end rolling mill, it is characterized in that: be fixedly connected with the material guide port supporting plate on the described frame, described material guide port is fixedly connected on the material guide port supporting plate.

According to described round end rolling mill, it is characterized in that: be rotatably installed with topping roll rotating shaft and bottom roll rotating shaft on the described frame relatively, described topping roll is fixedly mounted on the topping roll rotating shaft by last key, and described bottom roll is fixedly mounted on the top and bottom rolls rotating shaft by following key.

Owing to have breach on the topping roll of the present utility model, have down breach on the bottom roll, during rolling anchor pole, topping roll and bottom roll need not reciprocal rotation, only get final product along the rotation of same direction, generally rolling one, can go out finished product twice, can reduce wear and tear in machines like this, increase the service life the production efficiency height.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described:

A kind of round end rolling mill, as shown in Figure 1 and Figure 2, comprise base 12, frame 20 is installed on the base 12, is rotatably installed with topping roll 19 and bottom roll 13 on the frame 20 relatively, topping roll 19 is corresponding about in the of 13 with bottom roll, all have rolling ditch 22 on topping roll 19 and the bottom roll 13, have breach 18 on the topping roll 19, have down breach 14 on the bottom roll 13, last breach 18 is corresponding about in the of 14 with following breach; Be fixedly connected with material guide port 17 on the frame 20, material guide port 17 is corresponding with the slit between topping roll 19 and the bottom roll 13.Be fixedly connected with regulating block supporting plate 9 on the frame 20, be fixedly connected with the length back of the body female 6 on the regulating block supporting plate 9, length is carried on the back female 6 internal threads and is connected with length adjustment leading screw 8, one end of length adjustment leading screw 8 is fixedly connected with length adjustment handwheel 7, the other end of length adjustment leading screw 8 is connected with length adjustment piece 5, and length adjustment piece 5 is corresponding with material guide port 17.Be fixedly connected with material guide port supporting plate 15 on the frame 20, material guide port 17 is fixedly connected on the material guide port supporting plate 15.Be rotatably installed with topping roll rotating shaft 4 and bottom roll rotating shaft 10 on the frame 20 relatively, topping roll 19 is fixedly mounted on the topping roll rotating shaft 4 by last key 3, and bottom roll 13 is fixedly mounted on the top and bottom rolls rotating shaft 10 by following key 11.

The utility model is the lubricated round end rolling mill of oil injection type, it is the specific purpose tool of producing anchor pole, be mainly used in the colliery industry, be used for processing mining anchor pole (threaded anchor rod or rod bolt), can replace lathe stripping circle, but efficient than the high 5-7 of lathe stripping circle doubly strengthens material density by cold-rolling process, improve the tensile strength of anchor pole, install simple, safe and reliable to operation, capability of overload is strong, efficient is high, noise is low.
