Description

Metallic coil door leaf sheet milling train

The utility model relates to metal rolled plant equipment, specifically a kind of metallic coil door leaf sheet milling train.

At present, the general industrial and mining enterprises especially overlooking shop shop front is generally installed the aluminium alloy rolling door, because it is convenient that the aluminium alloy rolling door has switch, do not take up an area of face, style attractive in appearance, advantages such as safe antitheft, more and more be subjected to the favor of businessman, the high speed development of building with urban economy that improves constantly along with living standards of the people, rated wind velocity and appearance surfaces quality requirement to the aluminium alloy rolling door produced are also more and more high, the page or leaf sheet of aluminium alloy rolling door is to be formed aluminium alloy strips is rolling by milling train, common metallic coil door leaf sheet milling train, it is mainly by the motor that is installed on frame, reductor drives on one group, bottom roll constitutes, for example: Chinese patent CN2164330Y discloses the utility model that a kind of name is called " metal strip cold roll forming machine ", it is mainly by frame, wallboard, roll mandrel, on two groups, bottom roll, on laterally adjusting, the adjustment of bottom roll group distance, fastener, power transmission, compositions such as motor, though the rolling common metal band of its energy, but the structure of the adjusting device of this milling train is comparatively complicated, the volume of milling train is bigger, weight is heavier, the manufacturing cost height; Chinese patent CN2074217U discloses the utility model that a kind of name is called " non-pair cross rolling milling train ", it mainly is made up of frame, roll, bearing block, housing screw and bascule etc., the spacing of adjusting upper and lower roll stacks that is in operation this milling train realizes that with screw under the dynamic pressure of wrench plate being in operation, it is extremely inconvenient to adjust operation.

The purpose of this utility model be propose a kind of compact conformation on the basis of existing technology, operate steadily, operating noise is minimum, regulate upper and lower roll seam metallic coil door leaf sheet milling train extremely easily.

The purpose of this utility model is achieved by the following technical solution.

A kind of metallic coil door leaf sheet milling train, it mainly comprises the frame that is connected with guide groove plate, be installed on the wallboard on the frame, motor, driving belt, belt pulley is installed, the reductor of sprocket wheel, be supported on one group of bottom roll axle and one group of corresponding with it topping roll axle of wallboard by the top chock supporting by bearing, topping roll that its concave-convex surface shape matches and bottom roll are fixed in topping roll axle and bottom roll axle by key respectively, the end of one group of topping roll axle and bottom roll axle is equipped with pitch wheel, it is characterized in that: top chock is fixed in the adjusting briquetting that is installed on the wallboard by adjusting screw(rod), the top of adjusting screw(rod) is equiped with adjusting handle, the rotation adjusting handle can be regulated easily, gap between the bottom roll, it is extremely convenient to adjust operation, be connected in and be equipped with one group on the small wallboard frame of frame and proofread and correct roll, its objective is the surface of the metallic coil door leaf sheet of roll forming carrying out shaping, school shape and solid shape processing are handled, make the straight fineness of institute's rolled metal rolling door page or leaf sheet external form, can prevent effectively that institute's rolled metal rolling door page or leaf sheet from the surface occurring and running over and injure, mass defects such as burr can further improve the outer existing quality of metallic coil door leaf sheet.

The utility model also has following technical characterictic:

Topping roll of the present utility model, bottom roll and correction roll are after heat treatment to be made by the superior alloy steel material, can further improve the surface smoothness of institute's rolled metal rolling door page or leaf sheet, the working life that can prolong milling train again.

Reductor is a cycloidal planetary gear speed reducer, has overcome general milling train and has adopted the big disadvantage of the incident noise vibration of cylindrical gear reducer, can make metallic coil door leaf sheet milling train stable drive, greatly cuts down the consumption of energy and voice, further improves working environment.

The utility model is to adopt adjusting handle to mention by adjusting screw(rod) or the decline top chock, can regulate the gap between the upper and lower roll, it is extremely easy to regulate operation, and installs one group and proofread and correct roll on small wallboard frame, can further improve the presentation quality of institute's rolled metal rolling door page or leaf sheet.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is A-A cutaway view of Fig. 1.

Below in conjunction with accompanying drawing the utility model is further described.
