Manufacturing method of installation and adjustment device for steel strip mould of spiral air duct blower

The disadvantage of fixing the starting point of the steel strip mould directly to the bottom plate of the discharge outlet with two flat head screws is that when the steel strip mold needs to be replaced, the upper cover plate assembly device above the outlet bottom plate needs to be removed, and then the plate of processing pipe on the copper strip can be cut off. Finally, the two flat head screws fixing the starting point of the steel strip mold can be removed, and the operation process is complicated In order to solve this technical problem, one end of the starting point of the steel strip mold is fixed on the coupling device of dovetail groove and dovetail key, which is designed as dovetail groove and dovetail key. Although the improvement can make the steel strip mold can be drawn out or inserted into the dovetail groove along with the dovetail key, however, due to the application number of 2011102226545 The steel belt die will form a certain angle of the male and female mouth together. In the process of rolling and bonding through the bite wheel, when the steel strip mold is stressed, the dovetail key will be subjected to greater radial pressure in the dovetail groove. Therefore, one side of the dovetail key is easy to wear and tear, resulting in easy loosening of the starting screw of the steel strip mold fixed on the dovetail key, which often leads to failure, which affects the production efficiency and production efficiency Product quality;

[0004] the structure of fixing the end point of the steel strip mould on the adjusting block of the steel strip mould described in [0004] 2005201107214 is shown in Fig. 13-16. The fixed block is connected to the bearing support by two hexagon socket head screws, and the two surfaces of the sliding adjusting block are connected with each other. Then, the side clamp block is connected to the fixed block through the hexagon countersunk head screw The internal hexagon countersunk head screws are connected and pressed on different sides; when it is necessary to adjust the steel strip mold, it is necessary to loosen two hexagon socket cylindrical head screws on the upper and lower sides, and then tighten them after adjustment, which is troublesome for operation; another is that the fixed block adopts split structure, which makes the operation, adjustment and positioning quite inconvenient. Moreover, the structure composed of split parts makes it easy for the steel strip mold to bear force once it works The deviation phenomenon is obvious, which seriously affects the product quality.

[contents of utility model]

[0005] the purpose of the utility model is to provide a device for installing and adjusting the starting point of the steel strip mold, which can effectively overcome the large radial force generated during the rolling and bonding process of the occluding wheel, and can also make the steel belt mold draw out or insert into the groove; the second is to make the installation and adjustment device at the end of the steel strip mold have the advantages of convenient operation, adjustment and positioning, and can improve the fixation It is a kind of installation and adjustment device for steel belt mould of spiral air duct fan, which has the strength performance of block and does not produce deflection phenomenon under the stress of steel belt mold;

[0006] in order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the installation and adjustment device of the steel belt mold of the spiral air duct fan includes a frame, a bite assembly device, a steel belt mold, a fan-shaped frame, a steel belt mold support guide rail, a circumference support adjusting block, a milk wheel forming device, a control box, a discharging frame, an upper cover plate combination device, a cutting device and a bottom plate; and an outer arc of the steel strip mold is used to resist the device The utility model is characterized in that: one end of the starting point of the steel strip mold is fixed on the coupling device, and the coupling device is connected with the T-shaped sliding block through the sliding groove; one end of the end point of the steel strip mold is fixed on the adjusting block of the steel strip mold; the steel belt mold adjusting block includes adjustment Screw, fixed block, sliding adjusting block, upper pressing plate and bearing support; the fixed block is composed of a fixed side clamping block on the left side, the right side of the fixed block is fixed on the bearing support through the connecting piece, and the sliding adjusting block is equipped with adjusting screw; the fixed block is an integral structure, the left side of the fixed block is lower than the right side, and the cross-sections of the left and right sides are in the shape of "7" The shape of the head of the sliding adjusting block is consistent with the shape of the slot hole in the fixed block, and the tail of the sliding adjusting block is arranged between the upper surface of the left slot of the fixed block and the lower surface of the right slot and extends to the left. A steel band clamp is arranged on the left side of the fixed block and under the tail of the sliding adjusting block One end of the steel strip mould is clamped between the upper pressing plate and the sliding adjusting block of the adjusting block of the steel strip mould, and the upper pressing plate is connected with the sliding adjusting block and the steel band clamping block through screws to clamp the steel strip mould.
