Description
Technical field
The utility model relates to I-beam technical fields, are poured blank more particularly to a kind of preceding bridge I-beam.
Background technique
Automotive axle is connected by suspension with vehicle frame (or monocoque body), and wheel is installed at both ends.The effect of vehicle bridge
It is subject to the load of automobile, maintains normally travel of the automobile on road.Preceding bridge include I-beam, knuckle, track rod,
The parts such as wheel hub, brake.Wherein, preceding bridge I-beam section is in " I " fonts, therefore claims " I-beam ".Preceding bridge I-beam and preceding steel
Plate spring holder is integrally formed, and to avoid interfering with other component (such as engine sump tank), has downward drop in the middle part of I-beam.
I-beam is generally Integral die-forged forming, and for part engineering truck, such as fork truck, pump truck, body structure uses item
Part and passenger car difference are larger, therefore Ye You producer processes preceding bridge I-beam using casting technique.Since I-beam size is larger,
Overall weight is big, and when casting is more prone to produce mass defect, such as shrinkage porosite, misrun.
Summary of the invention
The purpose of this utility model is that in view of the deficiencies of the prior art, and a kind of preceding bridge I-beam casting blank is provided,
It is by the design of position, shape to running channel and riser, so that from both ends to intermediate setup when casting is cooling, bridge work before improving
The castability of word beam.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of preceding bridge I-beam is poured blank,
Two blank ontologies, running channel, four riser including parallel side-by-side setting, the running channel includes sprue, cross gate, the cross
Running channel is U-shaped, and the lower end of the sprue is connect with the middle part of the cross gate, under the spring perch of the blank ontology
Side is connect close to the side of bottom with the cross gate, and four riser are respectively arranged at blank ontology and spring perch pair
The position answered, the highest point of the cross gate are not higher than the highest point of countersink in the middle part of blank ontology.
The length along axial direction of the riser horizontal cross-section is greater than twice of the length along automobile direction of advance.
The cross gate vertical section is greater than length in the horizontal direction in the length of vertical direction.
Height of the height not less than the blank ontology of the sprue, riser, the sum of the volume of four riser
The half of the sum of volume for two blank ontologies
The beneficial effects of the utility model are: a kind of preceding bridge I-beam is poured blank comprising the two of parallel side-by-side setting
A blank ontology, running channel, four riser, the running channel include sprue, cross gate, and the cross gate is U-shaped, described directly to pour
The lower end in road is connect with the middle part of the cross gate, side and institute below the spring perch of the blank ontology close to bottom
Cross gate connection is stated, four riser are respectively arranged at blank ontology position corresponding with spring perch, the cross gate
Highest point not higher than countersink in the middle part of blank ontology highest point.The utility model casts two pieces blank simultaneously, improves casting
Make efficiency, side of the molten steel below spring perch close to bottom enters when casting, and gradually filled-type chamber, by running channel and
The position of riser, Adjusting Shape molten steel solidification sequence, when solidification, bottom, the both ends of blank first solidify, so as to improve preceding bridge work
The castability of word beam, avoids casting flaw.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the preceding bridge I-beam casting blank of the utility model.
Fig. 2 is the front view of preceding bridge I-beam casting blank in Fig. 1.
Fig. 3 is the right view of preceding bridge I-beam casting blank in Fig. 2.
Description of symbols:
1 --- blank ontology 2 --- running channel
21 --- sprue 22 --- cross gates
3 --- riser.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, is not that this is practical
Novel practical range limited to this.
As shown in Figure 1, Figure 2, Figure 3 shows, the preceding bridge I-beam of the present embodiment is poured blank comprising the two of parallel side-by-side setting
2, four a blank ontology 1, running channel riser 3, the arranged direction of two blanks is consistent, and spacing is the width of a blank ontology,
The running channel includes sprue 21, cross gate 22, and the cross gate 22 is the U-shaped being arranged symmetrically, under the sprue 21
End connect with the middle part of the cross gate 22, the side of the close bottom in the spring perch of the blank ontology 1 lower section with it is described
Cross gate 22 connects, and selects the position for the joint of running channel and type chamber, first is that molten steel can be made to flow to blank bottom as early as possible,
Second is that considering easy to operate when the running channel on excision blank.Four riser 3 are respectively arranged at blank ontology 1 and leaf spring
The corresponding position of seat, the highest point of the cross gate 22 are not higher than the highest point of 1 middle part countersink of blank ontology, four riser
3 need milling flat with joint later period of blank ontology 1, and the position thickness is larger, and position is higher, and far from end, are conducive to
Metal is full of the both ends of blank, carries out feeding to the position while cooling, improves product quality.
Further, the length along axial direction of 3 horizontal cross-section of riser is greater than the length along automobile direction of advance
Twice, the left and right directions along axial direction, that is, Fig. 2, the direction of vertical paper in automobile direction of advance, that is, Fig. 2 can from Fig. 1
To find out, the other parts in addition to upper end of riser 3 are offset flat shape, are conducive to carrying out feeding in longer length.
Further, 22 vertical section of cross gate is greater than length in the horizontal direction in the length of vertical direction.
Further, not less than the height of the blank ontology 1, described four emit the height of the sprue 21, riser 3
The sum of volume of mouth 3 is the half of the sum of volume of two blank ontologies 1.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
