Abstract
The utility model relates to an anchoring end rolling mill including a mill base, a frame, a roller set, a motor, and a decelerator. The anchoring end rolling mill is characterized in that the frame is arranged on the mill base, the roller set is a pair of rollers arranged on the frame in an up and down manner via bearings, the rollers are cylindrical in shape, the side surface of the right side of the center of each roller is formed by an arc surface and a non-arc smooth transition curved surface, the arc surface is the working face of each roller, the distance from any point on the non-arc smooth transition curved surface to the central axis of each roller is less than the radius of the arc surface which is 3/4 of the circumference, the arc surface is vertically connected with one side of the non-arc smooth transition curved surface to form a closed angle, and the arc surface is linearly connected with the other side of the non-arc smooth transition curved surface, the working faces of the two rollers of the roller set are symmetrically arranged, the left side of the center of each roller is provided with a broadening zone, and the broadening zones are provided with two connected semicircular holes. The anchoring end rolling mill provided is advantageous in being compact in structure and large in rolling moment, and being capable of ensuring the strength of the anchoring end and rolling the anchoring end met the width requirement as well.
Description
Technical field:
The utility model relates to a kind of anchored end milling train, belongs to the metal shaping equipment field.
Background technology:
Anchor pole is the main supporting accessory in coal mining enterprise's mine, and its essential structure is that shaft is a round steel, and anchored end or title anchor head end mostly are hot gadolinium or are swaged into band steel, turn round and make twisted shape.And shaft and anchored end must be made one.Used specification has various, and usually rock bolt shank is the round steel of ∮ 16mm, and the anchored end required thickness is not less than 4mm, and width is between 36 ± 1mm.Round steel with ∮ 16mm adopts rolling mill practice, makes the anchored end that satisfies above-mentioned requirements.The quality quality of anchor pole directly has influence on the security of operation in the mine, and general rolling equipment is difficult to the end of the round steel of ∮ 16mm evenly is extended to satisfactory size, and guarantees the intensity of its end.
Summary of the invention:
The purpose of this utility model provides a kind of anchor rod anchored end milling train that can satisfy the dimensional requirement of anchored end when guaranteeing anchored end intensity.
The purpose of this utility model is realized by following mode:
The utility model comprises support, frame, roll stacks, motor, decelerator, it is characterized in that: frame is located on the support, roll stacks is by the rack-mounted breaker roll of arranging up and down that is of bearing, roll is a cylinder, the side surface on the right side at roll center is made of arc surface and non-circular arc smooth transition curved surface, and arc surface is the working face of roll; All less than the radius of arc surface, arc surface accounts for 3/4 to any point on circumference to the distance of the axis of roll on the non-circular arc smooth transition curved surface, and arc surface and non-circular arc camber one side are vertical connection, form a wedge angle, and opposite side is that linearity is joined; The working face of two rolls of roll stacks is symmetrical arranged, and is provided with the broadening district in the left side at roll center, and roll broadening district is provided with two semi arch passes that join.
The utility model has the advantages that: compact conformation, roll torque is big, can roll out the anchored end of satisfied width requirement when guaranteeing anchored end intensity.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of breaker roll;
Fig. 3 is the side view of roll.
The specific embodiment:
With reference to accompanying drawing, the utility model comprises support 1, frame 11, roll stacks 9, motor 2, decelerator 5, and frame 11 is located on the support 1, and roll stacks 9 is by the bearing 10 rack-mounted breaker rolls of arranging up and down that are.Motor 2 is installed in the support, the output shaft of motor 2 is connected with decelerator 5 with belt 3 by belt pulley 4, the output shaft of decelerator 5 connects by the axle of the identical pitch wheel 7 with a pair of size of shaft coupling 6, meshed gears is connected with the axle of two rolls of roll stacks respectively, be provided with on frame 11 and adjust leading screw 8, motor 2 adopts interlocking rotating electric control system controls or two-direction switch control.Roll is a cylinder, and the right side at roll center is for flattening district 13, and its side surface is made of arc surface 15 and non-circular arc smooth transition curved surface 17, and arc surface is the working face of roll; All less than the radius of arc surface, arc surface accounts for 3/4 to any point on circumference to the distance of the axis of roll on the non-circular arc smooth transition curved surface, and arc surface and non-circular arc smooth transition curved surface one side are vertical connection, form a wedge angle 16, and opposite side is that linearity is joined; The working face of two rolls of roll stacks is symmetrical arranged, and is provided with broadening district 12 in the left side at roll center, and roll broadening district is provided with two semi arch passes 14 that join.
When rolling, at first should regulate and adjust leading screw according to the model of anchor pole, make top and bottom rolls keep required optimal spacing, earlier broadening being carried out in round steel stocking end handles, rolling in the pass 14 with feeding broadening district, round steel stocking end, take machine pre-induction feeding manner feeding then, the district is flattened in round steel stocking end feeding after the broadening processing, when 16 ones of wedge angles that forward arc surface and non-circular arc smooth transition curved surface vertical connection to when roll contact with stocking, stocking is taken out along feed direction, and milling train is finished rolling, and anchored end is rolled into satisfactory band steel, descend the road manufacturing procedure then, be about to the anchored end knob and become twisted shape.
