Description

Double Shaft Driving Rolling-cut Slitting Shear

The utility model belongs to the six connecting rod cutters that medium plate vertically is divided into two.

At present, domestic medium plate (4-50mm is thick) does not also have roll-turning subdivision to cut, and only is used for the circle shear of (steel plate is thick approximately less than 25mm) and the circle shear of rip cutting sheet metal (thick less than 10mm approximately) of cutting edge, and can shear the about 800Mpa of armor plate strength.

The purpose of this utility model is in order to give full play to existing heavy and medium plate mill production capacity, by behind the double chi width rolled plate, to cut into the steel plate of two identical or different width through subdivision, thereby filled up domestic blank.

The purpose of this utility model is such realization: rack-mounted two motors are all through the safety arrestment shaft coupling, cylindrical gear reducer and the left and right sides eccentric shaft that rotates synchronously in the same way, cooperate with static linear bottom knife rolling cut through the Gothic cutter of left and right sides connecting rod and guide post transmission upper tool post, blade clamps and quick replacement device, last bottom knife horizontal clearance adjusting device, frame clamps and mobile device, the front and back pinch roll, left and right sides rise and fall roller, the push broach device is installed on the frame, last bottom knife lap adjusting device is installed on the eccentric shaft, on, bottom knife is respectively with last, following tool rest is connected as a single entity with bolt, the spring clamping cylinder that upper cutter head and following tool rest unclamp with hydraulic cylinder is clamped in respectively on upper tool post and the lower slide, and lower slide is equipped with in four liftings, the hydraulic cylinder of following tool rest.

Bottom knife lap adjusting device is installed on the eccentric shaft of the described left and right sides, makes the upper tool post lifting by motor (or hydraulic motor), bevel gear, worm and wormwheel reductor, transmission eccentric bushing.

Gap blade is installed above the described frame adjusts transmission device, by motor, through reductor, the lifting of front and back worm-drive wedge.

In the described frame side panel spring being installed cuts somebody's hair.

The pressing plate of hydraulic cylinder transmission also is installed in the described frame side panel.

The and arranged on left and right sides of described lower slide is equipped with the rise and fall roller of hydraulic cylinder transmission.

Described bottom is equipped with the frame mobile device by motor, reductor, screw mandrel transmission.

Described bottom also is equipped with the machine frame fixture that is clamped by hydraulic cylinder (or spring).

Tool changing device by motor (or hydraulic motor) transmission is installed, wherein dolly liftable or mobile on the described frame.

Owing to take abovementioned technology, make and the utlity model has: it is good to shear plate quality, be that otch is bright and clean, smooth, shear the number of times height, and can make up with rolling-cut double side shear, replace with, the bottom knife time short (＜30 minutes), the gap blade adjustment time is short, accurately and reliably, the upper and lower blade lap adjustment time is short, accurately and reliably, shear steel plate thickness scope is greater than 4-50mm, steel plate width wide ranges 1000-5000mm, advantages such as the high 1300Mpa of intensity.

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