Abstract

The utility model provides a rear material-blocking device of a large-tonnage bending machine. The rear material-blocking device of the large-tonnage bending machine resolves the problem that a lifting rod and a guide rod are desynchronized when a supporting point of an existing rear material-blocking device is far, and comprises a base and a support located on the base, wherein a linear guide rail and a ball screw are longitudinally arranged between the base and the support, a front-rear servo motor is arranged at the end portion of the ball screw, lifting devices are arranged at two ends of the support, a lifting servo motor is arranged on the support, the lifting servo motor is connected with the lifting devices, a material-blocking beam is arranged at the top end of each lifting device, and a material-blocking claw is arranged on each material-blocking beam. The rear material-blocking device of the large-tonnage bending machine can achieve ascending and descending of a shaft R, is suitable for material blocking of warping workpieces, and effectively avoids the problem that the lifting rod and the guide rod are desynchronized when the original shaft R lifts and the supporting point is far.

Description

The large-tonnage rear material stopping device for bending machine
Technical field
The utility model belongs to mechanical field, particularly a kind of large and medium-sized numerical control bender rear material stopping device.
Background technology
Big-and-middle-sized numerical control bender generally all is equipped with rear material stopping device, realizes plate backgauge function, thereby realizes the accurate bending of plate.Backgauge has two classes behind traditional bender, and a class is backgauge behind the single shaft, i.e. backgauge after the X-axis can only be used for the backgauge of flat part, is not suitable for the backgauge of warped boar material after the bending; Another kind of be backgauge behind the diaxon (X ', R), in use there is very big problem in traditional back shelves material, and its primary structure is to adorn a Screw of Worm Gear lift in the middle of the backgauge, both sides have two guide posts, because the lifting fulcrum is in the centre, guide post is far away apart from fulcrum, can not keep synchronous when the both sides guide post moves up and down, during the elevating movement of backgauge beam, jitter conditions is arranged, and when serious, blocking can not lifting.More than after two classes backgauge all can not satisfy backgauge baffle plate needs behind the numerical control bender.
The utility model content
The purpose of this utility model provides a kind of large-tonnage rear material stopping device for bending machine, to solve fulcrum that existing rear material stopping device the exists asynchronous problem with guide post of elevating lever when far away.
For achieving the above object, the utility model is by the following technical solutions:
A kind of large-tonnage rear material stopping device for bending machine, comprise base, be positioned at the support of base top, vertically be provided with line slideway and ball-screw between described base and the support, servomotor before and after the end of ball-screw is provided with, the two ends of described support are provided with lowering or hoisting gear, also are provided with the lifting servomotor on the support, and the lifting servomotor is connected with lowering or hoisting gear, the top of lowering or hoisting gear is provided with the backgauge beam, and the backgauge beam is provided with backgauge and grabs.
Described lifting servomotor is provided with small pulley, and lowering or hoisting gear is provided with big belt wheel, and small pulley is connected by being with synchronously with big belt wheel.
The beneficial effects of the utility model:
Adopt the driven by servomotor belt wheel in the middle of the backgauge beam, by driving the both sides lowering or hoisting gear synchronously, the both sides lowering or hoisting gear is lowering or hoisting gear, is again guider again, the asynchronous problem with guide post of elevating lever when having avoided fulcrum far away.The lifting of R axle can be realized, the backgauge of warpage part can be fit to; When effectively avoiding former R axle lifting, the asynchronous problem with guide post of elevating lever when fulcrum is far away.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is work schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in Fig. 1-2, a kind of large-tonnage rear material stopping device for bending machine, comprise base, be positioned at the support 5 of base 10 tops, vertically be provided with line slideway 8 and ball-screw 11 between base 10 and the support 5, servomotor 12 before and after the end of ball-screw 11 is provided with, the two ends of support 5 are provided with lowering or hoisting gear 6, the middle part of support 5 is provided with lifting servomotor 3, lifting servomotor 3 is provided with small pulley 4, and lowering or hoisting gear 6 is provided with big belt wheel 7, and small pulley 4 and big belt wheel 7 are by being with 9 to be connected synchronously, the top of lowering or hoisting gear 6 is provided with backgauge beam 1, and backgauge beam 1 is provided with backgauge and grabs 2.
Assembling of the present utility model and the course of work are as follows:
After base 10 fixed, begin to assemble line slideway 8 and ball-screw 11, begin to assemble lowering or hoisting gear 6 then above support, assemble lifting servomotor 3, small pulley 4, big belt wheel 7 simultaneously, be with 9 synchronously, be connected to after adjusting on the line slideway 8, again front and back servomotor 12 is assembled to ball-screw 11 ends, treat that each top part all assembles and regulates after, assembling backgauge beam 1, backgauge pawl 2.When needs plate backgauge, front and back servomotor 12 drives ball-screws 11 and rotates, support 5 moves to the workpiece direction, moves to desired location and stops, backgauge pawl 2 backgauges, bender begins to fold plate, treat workpiece fold together curved after, workpiece becomes warpage, support 5 retreats, lifting servomotor 3 drives lowering or hoisting gear 6 liftings, treat to stop after backgauge pawl 2 is elevated to correct position, support 5 moves to desired location, backgauge pawl 2 backgauges, bender continues to fold plate, fold finish after, support 5 retreats, and workpiece is pulled out, finish a circulation, continue next workpiece and fold.
Backgauge behind the diaxon (X ', R), adopt the driven by servomotor belt wheel in the middle of the backgauge beam, again by the both sides of band drive synchronously lowering or hoisting gear, the both sides lowering or hoisting gear is lowering or hoisting gear, is again guider, the asynchronous problem with guide post of elevating lever when having avoided fulcrum far away.
Above-described only is preferred embodiment of the present utility model; should be understood that for the person of ordinary skill of the art; under technology enlightenment provided by the utility model; common practise as this area; other equivalent modifications and improvement can also be made, also protection domain of the present utility model should be considered as.
