Description
Technical field:
The utility model relates to a kind of impact extrusion press-loading apparatus, is specifically related to a kind of tank kiss-coating creeper tread base plate and bolt impact extrusion and presses connecting mold.
Background technology:
In the welding fabrication field, due to complexity and the diversity of welding moulding material, and the particularity of forming part structure, for the welding shaped structure, higher requirement has been proposed.For being connected of creeper tread base plate (50CrVA) and bolt (42CrMo), what adopt at present is technology of welding fabrication both, first welded part is preheating to uniform temperature to weld, and postwelding is incubated moulding again.And often due to the difficult parameters of weld preheating, postweld heat preservation with accurate assurance, cause welding equipment profiled part quality unstable, that parts occur in the later stage use procedure is easy to crack, intensity is low, welding is filled and caused the defectives such as interference, low precision, face of weld quality be coarse, and the shortcoming of this welding procedure is:
1. easily produce weld crack.Because material (50CrVA and 42CrMo) welding performance is poor, postwelding very easily produces the welding micro-crack, causes strength decreased.
Production cycle long, cost is high.Due to welding material particularity (50CrVA and 42CrMo), need material preheater before weldering, postwelding is incubated again, causes the production cycle long, and manufacturing cost is high.
3. product percent of pass is low.Because the time parameter of weld preheating, postweld heat preservation is difficult to accurate assurance, cause the profiled part scrappage high.
4. there are potential quality problems.The defectives such as filling interference, the surface quality that traditional welding technique causes is coarse.
Summary of the invention:
The utility model is by adopting a kind of Novel flushing extruding assembling device, solved easy to crack in creeper tread parts welding fabrication process, intensity is low, welding is filled and caused the serious problems such as interference, low precision.
The utility model is achieved through the following technical solutions:
connecting mold is pressed in a kind of tank kiss-coating creeper tread base plate and bolt impact extrusion, comprise the extruding punch device, Extruding die device and stop, the extruding punch device comprises the extruding punch, convex mould base, cope match-plate pattern, backing plate and guide pin bushing, the extruding punch is connected with backing plate, convex mould base is fixed with cope match-plate pattern by backing plate and is connected, on the extruding punch with the space of the body of bolt that holds bolt, the Extruding die device comprises Extruding die, lower bolster and guide pillar, on Extruding die with the space of the bolt head that holds bolt, guide pin bushing coordinates with guide pillar, stop is enclosed within on guide pillars and bushes, between cope match-plate pattern and lower bolster.
The utility model is broken through the boundary of traditional welding technique, adopt the impact extrusion technology of pressure mounting to solve creeper tread base plate (50CrVA) unstable with bolt (42CrMo) parts postwelding quality, overcome the micro-crack that traditional welding technique causes, the cracking that invisible crackle causes, the rosin joint undercut that causes in welding process and postweld heat preservation time can't precisely be determined the serious problems such as the parts welding fabrication intensity that causes is low.Adopt impact extrusion press-loading apparatus production efficiency high, be convenient to maintenance, not only reach and improve the quality of products, the purpose that reduces production costs also can really realize the cost efficiency of production process.
Description of drawings:
Fig. 1 is extruding punch device schematic diagram;
Fig. 2 is Extruding die device schematic diagram;
Fig. 3 is the stop schematic diagram;
Schematic diagram when Fig. 4 is the utility model work;
Fig. 5 is the top view of Fig. 4.
The specific embodiment:
Be illustrated in figure 1 as impact extrusion and press-fit extruding punch final-assembly die device, comprise extruding punch 5, convex mould base 2, cope match-plate pattern 1, backing plate 3 and guide pin bushing 10.Extruding punch 5 is connected with backing plate 3 by M8 screw 6, and convex mould base 2 is connected to be fixed with cope match-plate pattern 1 by backing plate 3, pin 4 and M10 screw and is connected, and pushes on punch 5 space 15 with the body of bolt that holds bolt 17.Be illustrated in figure 2 as impact extrusion and press-fit Extruding die final-assembly die device, comprise Extruding die 13, lower bolster 12, guide pillar 9 and attachment screw 14, on Extruding die 13 with the space 11 of the bolt head that holds bolt 17.Be illustrated in figure 3 as impact extrusion and press-fit stop 8.
as Fig. 4, shown in Figure 5, during work, creeper tread base plate 16 and bolt 17 are nested together are placed on Extruding die 13, wherein bolt head be positioned on Extruding die 13 with the space 11 of the bolt head that holds bolt, the part of the upper die drives extruding punch 5 and moves down, under guiding in guide pin bushing 10 and coordinating of guide pillar 9, extruding punch 5 contacts with creeper tread base plate 16 smoothly exactly, the body of bolt of bolt 17 part enters on extruding punch 5 in the space 15 with the body of bolt that holds bolt exactly, when extruding punch 5 touches creeper tread base plate 16, because extruding punch 5 strokes will be limited in very little scope this moment, stop 8 can guarantee to push punch 5 strokes in this scope, to guarantee the accurate moulding of parts, and unlikely cracking and dark impression is arranged on creeper tread base plate 16 surfaces.
The utility model is cast aside traditional welding technique, adopts new design concept, namely according to the law of minimum resistance of metal flow, by mfg. moulding die, makes metal flow be full of the gap of creeper tread base plate and bolt, and two part impact extrusion are integrated.In the mfg. moulding die process, the gap length of impact extrusion base plate and bolt has been carried out multiple trial, realize that finally mould impact extrusion technique connecting band track plate base plate and bolt produce tank kiss-coating creeper tread floor pan assembly.
