By adopting the press of the multi-guide-rod device, the bending effect is effectively guaranteed, under the identical length and bending force, the accelerating oil cylinder is adopted as a drive source, multi-point stress is achieved, the deformation of the worktables and slide blocks can be greatly reduced, a workpiece after being molded in a bending manner is small in angle error and good in linearity; by adopting four guide rods, and the unbalance loading resistance of the upper worktable can be improved, so that the geometric precision and the working precision of the press can be integrally improved.
Description
Technical field
The utility model relates to bender field, specifically a kind of forcing press of many guide rod device.
Background technology
Bender is for the bending and molding to panel beating material, there is the distinguishing features such as economy, safety, efficient and energy-saving and environmental protection, thereby, the development of bender is paid much attention in countries in the world, current bender at home and abroad generally adopts two cylinder bendings, sometimes large during with ten meters in length, adopt two-shipper four cylinder interlock bendings, but because length is long, two wallboard spans are excessive, so excessive to the upper and lower modification in the centre of workbench and slide block, also can cause the middle front and back of slide block bending, often Angular Dimension and the linearity of processing plate are not reached to requirement.
Utility model content
The purpose of this utility model is to provide a kind of forcing press of many guide rod device, ensure fruit of bending, make the workpiece angle error after bending and molding little, linearity is good, and improve the offset load resistance of upper table, thereby improve geometric accuracy and the operating accuracy of complete machine.
The technical solution of the utility model is as follows:
A kind of forcing press of many guide rod device, include frame, it is characterized in that: the top of described frame is respectively by four guide posts that have been slidably installed, the lower end of described four guide posts is fixedly connected with upper table, the top of frame is provided with the speedup oil cylinder for driving described upper table to move up and down, the bottom of frame is provided with lower table, on described upper table, the time relay is installed, one side of described frame is provided with electrical control cabinet, described electrical control cabinet is electrically connected with the described time relay on the one hand, be electrically connected with described speedup oil cylinder on the other hand.
The forcing press of described many guide rod device, is characterized in that: described frame both sides are installed with circular arc shrouding between described upper and lower workbench.
The beneficial effects of the utility model:
The utility model has effectively ensured fruit of bending, under equal length and bending power, adopts speedup oil cylinder as drive source, and multiple spot is stressed, and the modification amount of workbench and slide block reduces greatly, and the workpiece angle error after bending and molding is little, and linearity is good; Adopt four guide posts, improved the offset load resistance of upper table, thereby improved geometric accuracy and the operating accuracy of complete machine.
Brief description of the drawings
Fig. 1 is the utility model structure side view.
Fig. 2 is the utility model structural front view.
Detailed description of the invention
Referring to Fig. 1,2, a kind of forcing press of many guide rod device, include frame 1, the top of frame 1 is respectively by four guide posts 2 that have been slidably installed, the lower end of four guide posts 2 is fixedly connected with upper table 3, the top of frame 1 is provided with the speedup oil cylinder 4 for driving upper table 3 to move up and down, the bottom of frame 1 is provided with lower table 5, the time relay 6 is installed on upper table 3, one side of frame 1 is provided with electrical control cabinet 7, electrical control cabinet 7 is electrically connected with the time relay 6 on the one hand, is electrically connected on the other hand with speedup oil cylinder 4.
In the utility model, frame 1 both sides are installed with circular arc shrouding 8 between upper and lower workbench 3,5, have greatly improved the strength and stiffness of complete machine.
Below in conjunction with accompanying drawing, the utility model is further described:
1, the feature of four guide posts
1), improved the offset load resistance of upper table.Can be multi-faceted to workpiece press-fit, smoothing, bending and cut off.So not only expand the use envelop of function of complete machine, and improved significantly operating efficiency, alleviated labour intensity.
2) geometric accuracy and the operating accuracy of complete machine, have been improved.The use (being particularly used on the hydraulic press of large stroke) of four guide posts, has strengthened upper table driven mold traveling comfort and reliability.Not only improve a geometric accuracy such as perpendicularity that the depth of parallelism of upper table to lower table and upper table move to lower table face, also helped the operating accuracy that improves lathe.
2, speedup oil cylinder
Be 315t and following forcing press for nominal pressure, because the shortage in weight of piston rod and upper table is to allow its F.F. campaign reach desirable condition state, use speedup oil cylinder not only to make fast forward speed reach requirement faster, and make its fast forward speed more steady, and hydraulic system complexity coefficient has fallen at the end.
3, the mounting means of speedup oil cylinder is convenient to maintenance
Speedup oil cylinder has adopted assembling from the bottom up, and the structure being locked with large-scale round nut.So not only be convenient to install, transport, keep in repair, further improved operating efficiency, also simplified the processing technology that is installed together frame with oil cylinder simultaneously.
4, the adjusting of speed change point
The speed that moves down of upper table; conventional method realizes fast lower and slow lower speed change conversion by block control travel switch (or approach switch); because travel switch is arranged on guide rod place; position is too high; when adjustment, need to shut down and carry out; and also will be by realizing adjustment with instrument, make the conversion of upper table travel speed adjust troublesome poeration.The utility model is realized adjustment by the time relay, gives signal to the PLC in electrical control cabinet, controls the stroke speed change point of upper table, because the time is continued position that device installs the end of compared with, and convenient operation, and only need turning knob, easy-to-operate.
