Bar, after steel plate pressure is upper, after being under pressure elastic deformation occurs for elastic supporting bar so that the gap of feeding roller and nip rolls becomes
Greatly.The weight of steel plate determines that steel plate thickness is big by its thickness, then increases for the pressure of elastic supporting bar, elastic supporting bar
Elastic deformation increases, then the gap of feeding roller and nip rolls increases.The lower end of elastic supporting bar and the interior lower end face of groove are consolidated
Fixed welding.
Optimization, above-mentioned long steel plate punch press, the material lack warning device includes microswitch and power-off alarm, fine motion
The electric power loop of switch, power-off alarm connection punch press；Set fluted on the upper surface of the auxiliary extending bracket, fine motion is opened
Pass is arranged in groove, and microswitch is located in one of the lower section of feeding roller.
Microswitch in the application switchs for normally closed point, is disconnected after pressing.After feeding roller is pressurized, feeding roller touches
Dynamic microswitch, microswitch are disconnected, and power-off alarm is failure to actuate.When steel plate is used up, and feeding roller is not under pressure, feeding roller
Microswitch is not touched, microswitch is powered, and power-off alarm energization is alarmed.
In the application, the combinational circuit of multigroup microswitch and power-off alarm, each group microswitch interval can be increased
Set, can so be segmented remind operator's steel plate remaining length also how many.
Optimize, above-mentioned long steel plate punch press, some silica gel friction sleeves are provided with the nip rolls and feeding roller surface.
Silica gel friction sleeve can prevent steel plate from being skidded with nip rolls and feeding roller, increase frictional force.
