Shears machine working principle
Shears used to cut a straight line the edge of shearing machinesheet metal blank. Shearing process should be able to guarantee the expected linear shear surface and parallel degree requirements, and to minimize distortions plate in order to obtain high-quality work.
1. Shear trigger the working principle shearing machine
The working principle shears shown in Figure 4-2, on a fixed-blade knives to 2 in the upper and lower fixed blade 3 in 4 out of bed surface, the bed surface installed entrusted the ball 5, in order to facilitate the sheet into 6 Mobile, after retaining plate 7 for sheet positioning, location by the tune of 8-bit to regulate sales. Hydraulic pressure cylinder 9 pressed sheet metal used to prevent the sheet metal in the shear when flipped. Shelf plate 10 is safety devices to prevent accidents.
1) before adjustment baffle
to tailgate under the knife-edge, and then a model tailgate, the former model and fixed tailgate. Tailgate release, remove the model, fitted sheet, cut.
(2) adjusted baffle
Ping alignment will be a model for child care under the knife-edge, and then a model tailgate and fixed, remove the template, and then fitted with sheet metal cut.
(3) adjustment angle baffle
First model on the table under the knife-edge alignment, adjusting the angle baffle and fixed, and then adjusted according to model tailgate, shearing process using angle tailgate and tailgate to locate.
2. Shear structure of the trigger
Longmen shears
The goal is to apply more shears shears, because there is no hose rack shears u, we can only cut length (or width) than the length of a short blade plate. Gantry tilt angle of the blade shears small, rigid, and platen power per minute trips, and can be precision cut. Beams from the two beams under the panel through the connecting rod and fixed axis. Wall panels installed on seven roll axle, both with each axis roller beam axle on the gear with the gear mesh. Reduction gear and shaft of the lower part of the installation of the next beams through 6 under the roller drive gear and axle on the seven-phase meshing gears. Under the beam with bolts fixed in the middle rack.
Beams up and down on pin position, so that the beams could be along the pins with relative displacement under the beams toshearing machine adjust the gap between the upper and lower roller, and by regulating the flow-pressure adjustment screw.

Shan Ping institutions made
Figure 5-2 shown YZD3-16 single-ping machines mainly by the rack 1, Engine 3, the electrical 2, the work table 7, I. 9-foot 6 and shields and so on.
Rack part of structural steel welding, motor, movement of the lead foot, working platforms and shields were installed in the rack.
Some of the major movements from under the beams and beam components, and through targeted marketing and regulation of the composition of the working bodies of screw connections.
Beams from the two wall panels connecting rod through the beams, wall panels are 7 roller axle, axle on each roll are installed in the roller, roller wheel and gear outside. sheet metal duct connections, the widespread use of processing machinery. The use of bite .....
