Description
Technical field
The present invention relates to straightener, particularly a kind of press is fixed, the vertical hydraulic straightening machine of movable workbench.
Background technology
The vertical hydraulic straightening machine of prior art is sliding friction between working plate and the base, frictional resistance is big.In addition, during vertical hydraulic straightening machine aligning steel pipe, at first need the knee of steel pipe is erected, make crooked peak consistent with the Center of Pressure of master cylinder, then master cylinder again Vertical loading align.Because workpiece deformation is irregular, the cause of unbalance, is difficult to find accurately the aligning point, in the time of the master cylinder loading usually can occurring, the knee is not also aligned steel pipe and is just struck the beam, and needs repeatable operation just can finish the aligning task, and operating efficiency is very low.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of vertical hydraulic straightening machine is provided, frictional resistance is big between solution working plate and the base, and since irregular, the unbalance of workpiece deformation, the problem that steel pipe can lodge during aligning.
The present invention is achieved through the following technical solutions its goal of the invention.
A kind of vertical hydraulic straightening machine, comprise: frame, the workbench that is installed in frame lower, on base, moves, be arranged on left slew gear, the right-hand rotation mechanism of worktable upper surface, rack-mounted master cylinder, kicker cylinder and walking beam, be fixed on the pressure head on the walking beam, be arranged on two V-arrangement bearings of worktable upper surface, it is characterized in that: the two that is positioned at workbench below the described workbench is provided with four plunger cases and four wheels respectively, at the two ends of workbench main drive gear and slave hand actuator is installed respectively; The both sides of described frame, holding up materials device installing perpendicular to Workpiece length direction position symmetry.
The described materials device of holding up is installed in the both sides of frame by carriage, between carriage and the guide post guide pin bushing is housed, and the guide post front end connects holds up bin, and the rear end of guide post is connected with hydraulic cylinder.
Installation position, the rear portion displacement sensor of described hydraulic cylinder.
The present invention compared with prior art has the following advantages and beneficial effect:
1, owing to be provided with four plunger cases and four wheels at the workbench two ends, behind four cylinder jack-up workbench, motor reducer in the main drive gear drives the workbench move left and right, become rolling friction by original sliding friction, reduced resistance, reduce power of motor, reduce the use cost of press.And adopt frequency modulation, motor reducer that staring torque is big, can make workbench can the load startup, even running.
2, hold up materials device 11 owing to being provided with, in workpiece 16 dropping process, play a part to help workpiece, thereby guaranteed straightening quality, improved operating efficiency in the both sides of frame.
Description of drawings
Fig. 1 is a kind of structural representation of vertical hydraulic straightening machine;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the A portion enlarged drawing of Fig. 1.
Also the present invention is further illustrated by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of vertical hydraulic straightening machine, comprise: frame 1, the workbench 2 that is installed in frame lower, on base 15, moves, be arranged on left slew gear 4, the right-hand rotation mechanism 3 of workbench 2 upper surfaces, be installed in master cylinder 9, kicker cylinder 10 and walking beam 12 on the frame 1, be fixed on the pressure head 8 on the walking beam 12, be arranged on two V-arrangement bearings 5 of workbench 2 upper surfaces.
The steel plate weldment that described workbench 2 is box-shapeds, the two that is positioned at workbench below the workbench 2 is provided with four plunger cases 13 and four wheels 23 respectively, hydraulic oil enters upwards jack-up workbench 2 of plunger case 13, and release aftertable 2 drops on the frame 1, and press can pressurize and start working.
The two ends of described workbench 2 are installed main drive gear 6 and slave hand actuator 7 respectively, and the motor reducer in the main drive gear 6 drives workbench 2 move left and right.
Described seaming chuck 8 is fixed on a point that becomes the aligning workpiece on the walking beam 12, and two other V-arrangement bearing 5 all is arranged on workbench 2 upper surfaces, is the stressed member that bears straightening force, and it and V-arrangement seaming chuck 8 common three of constituting straightener align points.V-arrangement bearing 5, left slewing lifting mechanism 4 move along workbench 2 length directions.Two V-arrangement bearings 5 are symmetrically arranged in the press both sides during work, and ultimate range can not exceed the width of frame 1 between the two, and so, workbench 2 is a force transmission element rather than stressed member.Can significantly reduce the weight of base 15 and workbench 2.
Described left slew gear 4, right-hand rotation mechanism 3 also are arranged on workbench 2 upper surfaces.The former is fixed on the left end of workbench 2, and the latter can be along workbench 2 move left and right, and jack-up cylinder 14 can make it break away from bearing 5 by jack-up workpiece 16, and it is arbitrarily angled that workpiece 16 is rotated, so that check the flexibility of workpiece 16 and align the aligning position.
In workpiece 16 drops on process on the V-arrangement bearing 5, the reason lodging of, unbalance irregular owing to distortion for fear of workpiece 16, and can't find the aligning point, and be provided with and hold up materials device 11, in workpiece 16 dropping process, work to help workpiece.
The described both sides of holding up materials device 11 to be installed in frame 1 symmetrically, and perpendicular to workpiece 16 length directions.The described materials device 11 of holding up is installed in the both sides of frame 1 by carriage 17, between fixing carriage 17 and the movable guide post 19 guide pin bushing 18 is installed, and guide post 19 front ends connect holds up bin 20, and the rear end of guide post 19 is connected with hydraulic cylinder 21.Guide post 19 slides in guide pin bushing 18, is promoted guide post 19 and is held up bin 20 motions by hydraulic cylinder 21.
Because the diameter of aligning workpiece differs, required holds up the material stroke indefinite, is used for detecting the position of holding up bin 20 at the installation position, rear portion of described hydraulic cylinder 21 displacement sensor 22.
The aligning course of work:
Mix up the position of right-hand rotation elevating mechanism 3 and two V-arrangement bearings 5, workbench 2 right-hand members are left, and workpiece 16 is placed on left slew gear 4, above the right-hand rotation mechanism 3, returns after workbench 2 connects material.Jack-up cylinder 14 jack-up workpiece 16 make its rotating certain angle, and bending point upwards holds up materials device 11 to help workpiece 16 to drop on the V-arrangement bearing 5 up to it.Master cylinder 9 enters pressure oil, press pressurization beginning aligning.Master cylinder 9 releases then, kicker cylinder 10 bar chamber oil-feeds, press backhaul.Finish the process of once aligning.
