Abstract
The invention discloses a rear stop mechanism of a plate shearing machine, and relates to the technical field of plate processing, in particular to a plate shearing machine. The rear stop mechanism comprises a wallboard and a tool rest, wherein the wallboard is connected with a fulcrum shaft, a connecting rod is connected below the tool rest, the lower end of the connecting rod is detachably connected with a bracket, and the other end of the bracket is hinged with the fulcrum shaft; and the bracket is provided with an optical lever and a lead screw, the optical lever is arranged in parallel to the lead screw, the lead screw is connected with a sliding seat by screw thread, the sliding seat is sleeved outside the optical lever, the sliding seat is fixedly connected with a hanging seat, and the hanging seat is connected with a stop plate. The rear stop mechanism has the advantages that: 1, shift of the upper tool rest is not produced by adjusting the clearance of tool edges so as not to produce shift of a rear stopped material or cause plate size error; 2, a rear plate shearing size error is not produced by plate shearing distortion extrusion when a narrow plate is sheared; and 3, the joint of the bracket and the connecting rod is detachable, and the rear stopped material can be infinitely sheared after rotating 180 degrees, so the service range of the plate shearing machine is enlarged.
Description
Technical field
The present invention relates to technical field of board processing, relate in particular to a kind of plate shearing machine.
Background technology
At present both at home and abroad behind the plate shearing machine that uses backgauge directly installs and the plate shearing machine knife rest on, when knife rest moved up and down when plate shearing machine was worked, back backgauge was followed knife rest too and is done this motion.When the shear knife rest moved up and down, backgauge also moved up and down thereafter, and this moment, plate was close to striker plate, when shearing the narrow boards material, was easy to generate extruding back backgauge phenomenon because plate is sheared torsional deformation.Cause the plate scale error after the shearing, back backgauge distortion even fracture.General in addition plate shearing machine is when adjusting edge of a knife gap, and back backgauge can generally be contained on the backgauge of back because the backstop material level is put display unit, thereby then backgauge produce certain error along with upper tool post moves along with knife rest skew backward together.In use simultaneously, back backgauge can be subjected to the impact of plate, the long-term fracture of using general back backgauge connecting bolt can occur, and the scale error of shearing plate is bigger, even can cause striker plate to fall down from knife rest.The back backgauge of cut deal plate shearing machine is particularly evident.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, provide a kind of can shock resistance and can improve plate and shear dimensional accuracy, prevent the back stock stop of the plate shearing machine that the backgauge phenomenon takes place after the plate shear extrusion.
The object of the present invention is achieved like this: a kind of back stock stop of plate shearing machine, comprise wallboard and knife rest, connect a fulcrum on the described wallboard, the below of described knife rest connects a connecting rod, the detachable connection support in the lower end of connecting rod, the other end of support and described fulcrum are hinged; By bearing feed rod and leading screw are set on the support, feed rod and leading screw be arranged in parallel, and the slide that is threaded on the leading screw, slide are nested with outside feed rod, and the fixedly connected seat that hangs tight of slide hangs tight seat and connects striker plate.
Connecting rod of the present invention is installed in the knife rest below, and connects support, and the connecting rod two ends have hinge.Adjust edge of a knife gap when need, when skew takes place upper tool post, guarantee that this back backgauge can not be offset.Be connected the shock resistance that can increase the back backgauge on the wallboard with fulcrum.Connecting rod up-down adjustment device can be regulated the back backgauge after installation.When knife rest moved up and down, support was done oscillating motion around fulcrum, and the oscillating motion meeting makes connection striker plate thereon rapidly to back lower place motion, makes striker plate steadily break away from plate, torsional deformation in the time of can not shearing because of plate and produce the phenomenon of extruding back backgauge.Simultaneously hinge connection is detachable, behind the back backgauge Rotate 180 ° and the backgauge of fixing back, can carry out the endless shearing.A feed rod and a rhizoid thick stick are installed on support, are respectively applied for the guiding and the transmission of striker plate.
The invention has the beneficial effects as follows:
1, this back backgauge of drive that moves up and down of knife rest is done oscillating motion.Can not produce the upper tool post skew, and the skew that produces the back backgauge causes the plate scale error because of adjusting edge of a knife gap;
2, can be when not shearing the narrow boards material, plate is sheared torsional deformation extruding back backgauge and is produced and shear back plate scale error;
3, adopt fulcrum be connected and fixed with wallboard on, hang tight seat simultaneously and damping device be housed with the striker plate junction, the shock resistance of back backgauge is strengthened much than common back backgauge;
4, support and connecting rod hinge connection are detachable, and behind the back backgauge Rotate 180 ° and fixing back backgauge can carry out endless and shear, and enlarges the plate shearing machine scope of application.
In order to strengthen shock resistance, the step of outside protrusion is set on the striker plate, described hanging tight is provided with groove and through hole in the seat, and groove is connected with through hole, and the dish spring is set in the groove; One end of described striker plate is set in dish spring and the through hole, and by nut with hang tight the seat be connected, described step is arranged on the outside of dish spring.Hang tight seat and with the striker plate junction damping device is housed, the shock resistance of back backgauge is strengthened a lot than common back backgauge.
In order to improve the positioning accuracy of striker plate, the striker plate in the described through hole is provided with hollow adjusting bolt with hanging tight between the seat, and hollow adjusting bolt is threaded with hanging tight.Fine setting was used before and after hollow adjusting bolt was mainly used in striker plate.
