這種剪切機的一個主要特點是能夠進行快速換刀。更換刀片時，與快速更換軋鋼機軋輥相類似，能將上下刀臺從剪切機機架中抽出，而將另一組上下刀臺送入剪切機機架，大大縮短更換刀片的時間。為了適應快速換刀的要求，下刀臺安放在幾家下部，與機架接觸處設有滑板，而下刀臺通過夾緊油缸固定在機架上。
上刀臺有兩部分組成：上刀臺本體及上刀臺連桿墊塊。在換刀片時，只將上刀臺本體和下刀臺一起抽出。上刀臺由壓緊油缸固定在機架上。由于上下刀臺都由壓緊缸固定，這就便于裝卸。此剪切機的另一個主要特點是設置了上刀臺行程擴大裝置，以便能夠讓不需要剪切的大斷面軋件通過剪切機，上刀臺最大升高位置，可上升到軋制線以上640mm的位置。上刀臺行程擴大裝置是由一套連桿機構，以及油缸等組成。如需要擴大上刀臺行程時，拔掉安全銷，將上刀臺壓緊油缸松開，上刀臺在其平衡油缸作用下，下降落在下刀臺上。此時，上刀臺行程擴大裝置的油缸動作，連桿機構的端部插入能轉動曲柄的凹槽中，使曲柄轉動一個角度。這樣，曲柄連桿擺動起到一定位置。然后，上刀臺平衡油缸再次動作，使上刀臺上升到離軋制線上640mm的位置。為了保證連桿機構在轉動曲柄連桿時，其端部不脫出轉動曲柄的凹槽，設置了一個平衡重機構。

One of the main characteristics of the shear machine is capable of rapid change. When replacement blades, with fast change is similar to rolling mill roll, can be pumped up and down the knife from the shear machine frame, and another set of top and bottom knife into shearing machine rack, shorten the time of replacement blades. In order to adapt to the requirement of rapid change, the knife taian on several bottom, contact with the rack is equipped with a skateboard, and under the knife sets through the clamping oil cylinder is fixed on the rack.
Knife knife machine has two parts: on ontology and knife on the connecting rod block. When in the blade, only will be under the knife on the ontology and knife set out together. Knife on the table by the pressure oil cylinder is fixed on the rack. Due to the top and bottom knife sets are made by pressure cylinder is fixed, it is convenient for loading and unloading. Another key feature of the shearing machine is set up on the knife stroke expanding device, so that you can let don't need to cut the big cross section of rolling piece by cutting machine, knife sets the biggest rises on location, can rise to the position of the rolling line more than 640 mm. Knife on Taiwan to expand device consists of a set of connecting rod mechanism, and the oil cylinder, etc. Such as the need to expand on the knife sets the trip, remove the safety pin, will the knife pressure oil cylinder to loosen, the knife on the table under the effect of the balance cylinder, the drop falls on the first cut. At this point, the knife on Taiwan to expand device of the oil cylinder action, can crank linkage end into the groove, a crank Angle. In this way, the crank connecting rod swing play a position. Then, knife sets balance oil cylinder action again, make the knife set to rise to the position of the rolling line is 640 mm. In order to ensure the linkage in the crank connecting rod, its not emerge the crank groove, set up a balance weight.
