Abstract
The utility model discloses a guiding device of press ram and relates to a lead rail device of press ram. A ram is driven by a connecting rod and connected with a lead rail mechanism. The lead rail mechanism comprises a central lead rail mechanism which is arranged in the center of the ram, and side open lead rail mechanisms which are arranged at the two sides of the ram. The central lead rail mechanism comprises a central guide pole fixed together with the ram as a whole and a central guide sleeve fixed together with a machine body as a whole; and the central guide pole is glidingly connected with the central guide sleeve. The side open lead rail mechanism comprises a pair of strip-shaped raised blocks arranged at the two sides of the ram, and a guide base fixedly connected with the two sides of the machine body. The bottoms of the strip-shaped raised blocks are fixedly connected with the sides of the ram; and the guide base is provided with a working surface parallel with the cross section of the ram; a front side and a back side which are vertical to the bottom of the strip-shaped raised block and parallel with the cross section of the ram are respectively connected with the working surface on the guide base in a gliding way. The guiding device can overcome the impact on the lead rail for the displacement caused by unbalance loading and for elastic deformation caused by attack; thus, the guiding device can ensure the accurate, stable and reliable movement of ram.
Description
Technical field
The utility model relates to a kind of track-type facilities of press ram, relates in particular to the improvement for the guide rail of press machine device.
Background technology
Existing forcing press, the direction of motion of slide block has six in three dimensions, shown in figure 5,6,7, do straight reciprocating motion with vertical plane (lateral cross section of slide block), Y-axis that the Z axle constitutes with vertical plane (longitudinal cross-section of slide block) upper edge X, Y, Z axle that the Z axle constitutes in horizontal plane (horizontal cross-section of slide block), X-axis that X-axis and Y-axis constitute, and rotate around X, Y, Z axle and to be total to six-freedom degree.
For making the operate as normal of forcing press, need five frees degree in the relative motion six-freedom degree between restriction slide block and the fuselage, it is moved reciprocatingly along slide block lateral cross section and longitudinal cross-section intersecting lens direction with respect to fuselage, promptly keep slide block to do straight reciprocating motion along Z axle (X, Y face intersecting lens) direction.Realize above-mentioned need of work be provided with track-type facilities at present commonly used two kinds of versions are arranged.The one, the octahedral planar guide, this kind guide frame is simple, and is easy to process, be convenient to adjust, but the precision stamping that can't adapt to when eccentric load is arranged processed the inordinate wear that reason leads about being.The 2nd, the cylinder guiding, as shown in Figure 3, the guiding accuracy height of this kind guidance mode, but the precision stamping that can't adapt to equally when eccentric load or slide block distortion are arranged is processed; When the bearing pressure of slide block middle part, micro-elastic deformation area 12 can appear in slide block, and this deformed area 12 can cause top, side towards outside projection in the slide block two sides, occurs inordinate wear district 1, worn area 2 11 between guide pillar and guide pin bushing.Its reason is that the pressure that strain forms makes the pressure jump between guide pin bushing and the guide pillar, causes the inordinate wear district corresponding with deformation direction because the guide pin bushing of slide block side is limited by guide pillar.This service life to lathe, machining accuracy have produced very big influence, and in addition, the frequent inordinate wear that occurs has caused the increase of maintenance cost.
The utility model content
The utility model is at prior art problems, provide a kind of under the prerequisite that keeps five frees degree accurately to limit, by discharging alignment restrictions, avoided because the guider to the press ram of the inordinate wear of guide rail mechanism that produces appears being out of shape in slide block when withstanding shocks load to slide block deflection maximum region.
The technical solution of the utility model is: slide block is driven by connecting rod and by can keeping its guide rail mechanism flexible connection that moves reciprocatingly along slide block lateral cross section and longitudinal cross-section intersecting lens direction with respect to fuselage, the open guide rail mechanism in side of the two sides that described guide rail mechanism comprises the center rail mechanism that is arranged on the slide block center, be arranged on slide block; Center rail mechanism comprise the center guide pillar that is fixed with one with slide block, with the center guide pin bushing that fuselage is fixed with one, center guide pillar slides with the center guide pin bushing and links to each other; The open guide rail mechanism in side comprises a pair of bar shaped projection that is arranged on the slide block two sides, the guide holder that is fixed on the fuselage both sides, the bottom surface of bar shaped projection and slide block side are connected, guide holder is provided with the working face that is parallel to the slide block lateral cross section, with bar shaped projection bottom surface vertical two be parallel to forward and backward of the slide block lateral cross section respectively with guide holder on working face slide and link to each other.
The open guide rail mechanism in described side also comprises guide rail, and guide rail is fixed on the bar shaped projection or on the guide holder.
Guider of the present utility model, by the straight reciprocating motion of the center rail mechanics limit slide block that is arranged on the slide block centre along X axis, have the side that is arranged on the slide block both sides open guide rail mechanism restriction slide block along Y-axis to straight reciprocating motion, in addition, above-mentioned two mechanisms have limited the rotary freedom of slide block along X, Y, Z axle respectively; Guaranteed slide block at Z to doing straight reciprocating motion.Changed guiding mechanism in the past be set to realize X to restriction to slide block side plane restriction location, thereby the situation of inordinate wear has appearred producing when strain appears in slide block.Discharged the restriction to the side end face of slide block deflection maximum, the restriction of X axis has been changed into be arranged on the center, in the restriction that has realized X axis, the distortion of slide block can not produce any influence to guide rail mechanism of the present utility model.Exquisite composition of the present utility model can overcome because of displacement that unbalance loading causes, impact the influence to guide rail mechanism of the strain that causes, guarantees that slide block can accurate, reliable and stable motion.
