Description
Technical field
The utility model relates to vertical hydraulic press, particularly a kind of suspension arrangement of forging press middle cross beam.
Background technology
Vertical hydraulic press generally is made up of entablature, middle cross beam, sill, is connected as a whole between three crossbeams with Vertical Rack.Middle cross beam (claiming slide block again) is as the parts that move up and down in the press, in its travel range, mould etc. transmitted pressure.Generally above the middle cross beam both sides, suspension arrangement is housed, when equipment stops for a long time or safeguards, leans on suspension arrangement will be in the high-order middle cross beam of press and hold, prevent middle cross beam because deadweight is glided.Suspension arrangement in the past drives pressure pin by piston-type hydraulic cylinder and in fairlead, moves, and piston rod drives pressure pin and stretches out, and inserts in the respective aperture of middle cross beam, realizes the fixedly purpose of middle cross beam.This employing pressure pin inserts the suspended structure in the middle cross beam hole; Though simple and practical, the deficiency that exists is: pressure pin inserts in the middle cross beam hole, and both have the certain precision requirement at " to the hole "; In addition, some press is subject to the press space and can't adopts this kind suspension arrangement.
The utility model content
The purpose of the utility model is to remedy the deficiency of prior art, and a kind of suspension arrangement of hydraulic press middle cross beam is provided, and solves to adopt pressure pin to insert the unreasonable problem that the suspended structure in the middle cross beam hole exists in the past.
The utility model is realized through following technical scheme.
A kind of suspension arrangement of hydraulic press middle cross beam; Comprise: driving oil cylinder, pressure pin, guider, the piston rod of said oil cylinder is connected with pressure pin through screw thread, and said guider is made up of guide holder, screw, the long key of level, vertical key and guideway; Said guide holder is fixed on the column through screw; Long key of level and vertical key are housed between said guide holder and the column, said guideway and said guide holder interference fit, said pressure pin and said guideway are slidingly matched; It is characterized in that: said pressure pin right-hand member is provided with horizontal plane upwards; Said piston rod is provided with the rotation preventing device of being made by thin plate, has the hole of passing said piston rod on the said rotation preventing device, and clamps with the piston rod end screw thread, and said rotation preventing device has one side to be against on the said column; Said pressure pin is provided with device for detecting distance of travel; Said device for detecting distance of travel by two near switch with form near switch bracket and induction contact accordingly; Saidly be installed on the said column near switch bracket; Two said is installed in saidly near above the switch bracket near switch, said induction contact is welded on the said rotation preventing device.
The utility model compared with prior art because the pressure pin right-hand member is provided with horizontal plane upwards, when the piston rod level moved right, the pressure pin right-hand member reached the lower plane of middle cross beam, the horizontal plane that pressure pin makes progress can be held middle cross beam, and middle cross beam is hung; Because piston rod is provided with rotation preventing device, the horizontal plane that has guaranteed to be used on the pressure pin to hold middle cross beam can not rotate, thereby guarantee that suspension is reliable all the time up; Owing to be provided with device for detecting distance of travel, can know the particular location of pressure pin, thereby can accurately control the stroke that pressure pin seesaws.The utility model is used for vertical hydraulic press, have rational in infrastructure, easy and simple to handle, hang reliable advantage.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the vertical view of the utility model.
The utility model is elaborated through preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
Like Fig. 1, shown in 2; A kind of suspension arrangement of hydraulic press middle cross beam; Comprise: driving oil cylinder 1, pressure pin 2, guider 3, the piston rod 1-1 of said oil cylinder 1 is connected with pressure pin 2 through screw thread, and said guider 3 is made up of guide holder 3-1, screw 3-2, the long key 3-3 of level, vertical key 3-4 and guideway 3-5; Said guide holder 3-1 is fixed on the column 6 through screw 3-2; Long key 3-3 of level and vertical key 3-4 are housed between said guide holder 3-1 and the column 6, said guideway 3-5 and said guide holder 3-1 interference fit, said pressure pin 2 is slidingly matched with said guideway 3-5; Said pressure pin 2 right-hand members are provided with horizontal plane 2-1 upwards; Said piston rod 1-1 is provided with the rotation preventing device of being made by thin plate 4, has the hole of passing said piston rod 1-1 on the said rotation preventing device 4, and clamps with piston rod 1-1 end thread, and said rotation preventing device 4 has one side to be against on the said column 6; Said pressure pin 2 is provided with device for detecting distance of travel 5; Said device for detecting distance of travel 5 by two near switch 5-1 with form near switch bracket 5-2 and induction contact 5-3 accordingly; Saidly be installed on the said column 6 near switch bracket 5-2; Two said is installed in saidly near above the switch bracket 5-2 near switch 5-1, said induction contact 5-3 is welded on the said rotation preventing device 4.
When piston rod 1-1 level seesaws in the driving oil cylinder 1, drive pressure pin 2 level in guideway 3-5 and seesaw.Piston rod 1-1 level moves right, and pressure pin 2 right-hand members reach the lower plane of middle cross beam 7, and the horizontal plane level of pressure pin 2 is upwards held middle cross beam 7.In this stress model, pressure pin 2 receives shearing and bending stress straight down, passes to guider.Wherein the screw 3-2 in the guider can bear necessary moment of torsion, and long key 3-3 of level and vertical key 3-4 can bear clockwise distortion.
Because the piston rod 1-1 in the driving oil cylinder 1 has the possibility of rotation when in oil cylinder, moving, therefore, therefore, can cause pressure pin 2 to rotate.For the horizontal plane that guarantees to be used on the pressure pin 2 to hold middle cross beam 7 all the time up, needing increases rotation preventing device 4, rotation preventing device 4 is made by a thin plate, perforate on the thin plate.Piston rod 1-1 end screw thread is passed in this hole, and piston rod 1-1 and pressure pin 2 are clamped, and simultaneously, an end face of rotation preventing device 4 props up the column face, so just can guarantee that piston rod 1-1 can not rotate in level seesaws process.
In order to control the stroke that pressure pin 2 seesaws, be provided with device for detecting distance of travel 5, device for detecting distance of travel 5 by two near switch 5-1 with accordingly near switch bracket 5-2, induction contact 5-3 forms.Be installed on the column near switch bracket 5-2, two are installed in above the switch bracket 5-2 near switch 5-1, and induction contact 5-3 is welded on the rotation preventing device 4.Induction contact 5-3 can move with pressure pin 2.Through near switch 5-1 and induction contact 5-3 at different motion location sensitive sender, know the particular location of pressure pin 2, thus the motion of piston rod 1-1 in the control driving oil cylinder 1.
