The hot shears of the utility model, the top of said cutting head is provided with worm gear pair, and said worm gear pair is connected on the worm drive motor, the rotation of said worm drive Electric Machine Control turbine, the original position that the restriction cutting head vertically moves.
Owing to adopted said structure, can rotate the rotation that cooperatively interacts of worm screw turbine through control worm drive driven by motor worm screw; Turbine rotation, and through the moving of device such as screw mandrel control cutting head in the vertical direction, and limit original position and the final position that its in the vertical direction moves; Thereby the shift motion of control cutting head therefore can be through control worm drive motor, the shift motion of adjustment cutting head; Shearing with the steel plate that adapts to different-thickness makes the scope of application wide.
The hot shears of the utility model, the top of said cutting head is provided with spring, the recovery after the up-downgoing of control cutting head.
Owing to adopt said structure, mounting spring on the top of cutting head, thereby when cutting head move downward shear after; Can give its buffering and elastic force through spring, make it can return to the trend of reset condition, same reason; After cutting head moves upward; Still can give its shock resistance through spring, and elastic force is provided, make it can return to the trend of reset condition.The hot shears of the utility model, simple in structure, easy and simple to handle, can shear processing to steel board, particularly the higher steel plate of temperature.
The hot shears of the utility model; Said gear pair comprises second gear, the 3rd gear and the 4th gear; Said second gear and first gears engaged; With the gears engaged of the second gear coaxial rotation the 3rd gear is arranged, with the gear and the 4th gears engaged of the 3rd gear coaxial rotation, said the 4th gear is connected on the flywheel drive motors.
Owing to adopted said structure, can control the 4th gear driven the 3rd gear and rotate through control flywheel drive motors, the 3rd gear is controlled second gear again and is rotated; Control first gear by second gear at last and rotate, the first design of gears gear is bigger, and is similar to the structure of flywheel, makes to win gear after being driven rotation; Can storage power, and through cooperating between crank throw and the connecting rod, drive the cutting head in the vertical direction and move up and down; Thereby the impulsive force with moment can extremely fast be sheared steel plate, thereby guarantees that shear effect is good; Make that the steel plate otch after shearing is even, avoid repeating polishing, reduce cost.
The hot shears of the utility model, said cutting head be provided with cutting edge, the oblique angle of said cutting edge is 2 °.
Owing to adopted said structure, the oblique angle of cutting edge is 2 °, makes that the cutting edge of cutting head is sharp, when needs are sheared steel plate, can moment steel plate be cut away, and the limit mouth of excision is even, can satisfy the production demand.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
1. the hot shears of the utility model is simple in structure, and is convenient to operation;
2. the hot shears of the utility model can be sheared processing to steel board, and particularly the higher steel plate of temperature makes that the steel plate otch after shearing is even;
3. the hot shears of the utility model avoids repeating polishing, reduces cost, and highly versatile is beneficial to popularization.
