Application of the QC11Y sheet metal guillotine shearing machine with E21S controller
The QC11Y sheet metal guillotine shearing machine with E21S controller was developed by our highly skilled engineers for the shearing process in metal fabrication used in the following applications: aviation industry, light industry, metallurgical industry, chemical industry, architecture industry, shipbuilding industry, auto industry, power industry, electric appliance industry and decoration industry. This type of equipment is suitable for use with stainless steel, iron, copper, and aluminum workpieces.

The shear features a gate structure and is composed of a machine rack, knife rest, blade gap adjustment system, material pressing system, front gauge, back gauge, hydraulic system and Siemens electrical system.

Estun E21S CNC system
1. The QC11Y sheet metal guillotine shearing machine with E21S controller features a high definition liquid crystal display screen and programs quickly and conveniently;
2. The intelligent location of the back gauge to eliminate the mechanical hand location;
3. The QC11Y sheet metal guillotine shearing machine with E21S controller installs the timer relay inside, for easy, low cost operation.
4. The machine has the function of shearing angle adjustment inside, does not need the indicator light and button;
5. The encoder of the QC11Y sheet metal guillotine shearing machine with E21S controller has feedback on the blade edge gap and real time displays the blade edge gap size;
6. The machine has the function of one key backup and recovery;
7. To the encoder of the QC11Y sheet metal guillotine shearing machine with E21S controller, all the buttons are micro switches. And the machine has the tests of EMC, high and low temperature and vibration to ensure the stability and use age of the product.
8. Pass the CE identification

The workbench of the sheet metal guillotine hydraulic shear is featured with rolling steel ball structure, as it decreases the friction of injecting material, protecting the product surface, and also increases the security of the operator.
The blade of QC11Y sheet metal guillotine shearing machine with E21S controller uses alloy tool steel, which is wearproof and can sustain impulsive loads;
The Swaging cylinder has a spring and there is a special spacer in the bottom, thus ensuring that soft metals like aluminum does not become damaged when injected.

The sheet metal guillotine hydraulic shear is assembled with Schneider electric components for stable operation.
To the QC11Y sheet metal guillotine shearing machine with E21S controller, with the DELTA frequency changer can ensure the location device does not swing horizontally and increase the location accuracy;
When the electric cabinet door is open, the machine automatically shuts off as a safety feature.

The hydraulic control system of the sheet metal guillotine hydraulic shear adopts a hydraulic valve supplied by Rexroth or First to control the up and down movement of the shear's cutting board.
