Description

One combines gear ring forging mold
Technical field
The present invention relates to Design of Dies technical field, particularly relate to one and combine gear ring forge mould Tool.
Background technology
It is mechanically to use one of quite varied part in conjunction with gear ring, can be with casting, forging Processing etc. method, the combination gear ring error that the method for casting is worked it out is big, generally requires reprocessing, Less economical, and affect workpiece strength, traditional forging method processing combines gear ring, upper and lower mould Fixing unreliable, easily cause the mismachining tolerance that part comparison is big, therefore a kind of upper mold of design and Upper mould fixed plate is fixing reliable, and lower mold is formed with lower mold fixed plate and is reliably connected, and adds in conjunction with gear ring The combination gear ring forging mold that work error is little seems the most necessary.
Summary of the invention
The purpose of the present invention is contemplated to overcome prior art processing to combine gear ring needs reprocessing, Less economical, affect workpiece strength, upper and lower mould fixes insecure defect, devises a kind of knot Close gear ring forging mold, upper mold and upper mould fixed plate fixing reliable, lower mold and lower mold fixed plate shape One-tenth is reliably connected, little in conjunction with ring gear machining error.
Solve the technical problem that required by the present invention and can be achieved through the following technical solutions:
One combines gear ring forging mold: include upper die and lower die, upper mould fixed plate, lower mold Fixed plate, push rod, bolt, combining gear ring, described upper mold is solid with described upper mold with described bolt Determining plate and be connected as an entirety, described lower mold and described lower mold fixed plate inlay combination, described top Bar inserts in the hole of described lower mold and described lower mold fixed plate, and the blank of described combination gear ring is placed in In the circular groove of described lower mold.
The stepped through hole of band, the top of described upper mold are processed in described upper mould fixed plate middle Middle is machined with screw, this screw axis and the axis collinear of upper mould fixed plate interstitial hole.
The centre of described lower mold fixed plate is machined with cylindrical groove, the external diameter of described lower mold and this groove Upper lower deviation meet interference fit relation.
Through hole is also processed in described lower mold and described lower mold fixed plate middle, and both inlay combination After this axially bored line conllinear.
Shoulder hole, the head of push rod upper end are processed in the top of the middle bottom through-hole of described lower mold Portion is embedded in the hole that shoulder hole lower diameter is less, and the aspect ratio shoulder hole bottom of its head The height in hole is little.
Owing to have employed above technical scheme, present invention have the advantage that
Upper die and lower die, upper mould fixed plate, lower mold fixed plate, push rod, bolt is used to combine Designed combination gear ring forging mold, upper mold and upper mould fixed plate be connected with, fixing can Leaning on, the centre of lower mold fixed plate is machined with cylindrical groove, and the external diameter of lower mold is the most inclined with this groove Difference meets interference fit relation, and lower mold is embedded in the cylindrical groove of lower mold fixed plate, and formation can By connecting, through hole is also processed in lower mold and lower mold fixed plate middle, and both should after inlaying combination Axially bored line conllinear, it is ensured that the bar portion below push rod can insert from this hole swimmingly, and combines tooth Circle mismachining tolerance is little, and shoulder hole is processed in the top of the middle bottom through-hole of lower mold, it is ensured that quilt It is an enclosed construction that processing combines in the middle of gear ring.
Accompanying drawing explanation
Fig. 1 is the full cut-away illustration of present configuration;
Fig. 2 is processed by the present invention combines the full cut-away illustration of gear ring;
In figure each assembly and reference be respectively as follows: 1, upper mold;2, lower mold;3, upper mold is solid Determine plate;4, lower mold fixed plate;5, push rod;6, bolt;7, gear ring is combined.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be prone to effect Understand and understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.
One combines gear ring forging mold, including upper mold 1, lower mold 2, upper mould fixed plate 3, Lower mold fixed plate 4, push rod 5, bolt 6, combine gear ring 7, upper mold 1 bolt 6 and upper mold Fixed plate 3 is connected as an entirety, and lower mold 2 and lower mold fixed plate 4 inlay combination, push rod 5 Inserting in the hole of lower mold 2 and lower mold fixed plate 4, add man-hour, the blank in conjunction with gear ring 7 is placed in In the circular groove of lower mold 2, upper mold 1 moves downward and combines gear ring 7 needed for extrusion blank is formed.
The stepped through hole of band is processed in upper mould fixed plate 3 middle, the center, top of upper mold 1 Between be machined with screw, during installation, the axis collinear of this axially bored line and upper mould fixed plate 3 interstitial hole, The bar portion of bolt 6 inserts from upper mould fixed plate 3 interstitial hole, and screw middle with upper mold 1 screws, Its head is supported by the step surface of upper mould fixed plate 3 shoulder hole, by upper mold 1 and upper mould fixed plate 3 are fixed together.
The centre of lower mold fixed plate 4 is machined with cylindrical groove, and the external diameter of lower mold 2 is upper with this groove Lower deviation meets interference fit relation, and lower mold 2 is embedded in the cylindrical groove of lower mold fixed plate 4, Formation is reliably connected.
Through hole is also processed in lower mold 2 and lower mold fixed plate 4 middle, and both should after inlaying combination Axially bored line conllinear, it is ensured that the bar portion below push rod 5 can insert from this hole swimmingly, and combine Gear ring 7 mismachining tolerance is little.
Shoulder hole, the head of push rod 5 upper end are processed in the top of the middle bottom through-hole of lower mold 2 Portion is embedded in the hole that shoulder hole lower diameter is less, and the aspect ratio shoulder hole bottom of its head The height in hole is little, and when upper mold 1 moves downward, the upper surface of its bottom surface and push rod 5 leaves one end Distance so that be an enclosed construction in the middle of processed combination gear ring.
Combination gear ring forging mold disclosed in this invention, upper mold 1 and upper mould fixed plate 3 use spiral shell Bolt 6 connects, and fixing reliable, the centre of lower mold fixed plate 4 is machined with cylindrical groove, lower mold 2 The upper lower deviation of external diameter and this groove meet interference fit relation, lower mold 2 is embedded into lower mold and fixes In the cylindrical groove of plate 4, formation is reliably connected, and lower mold 2 and lower mold fixed plate 4 middle are also Being processed into through hole, both inlay this axially bored line conllinear after combination, it is ensured that the bar portion below push rod 5 Can insert from this hole swimmingly, and it is little to combine gear ring 7 mismachining tolerance, the middle of lower mold 2 Shoulder hole is processed in the top of bottom through-hole, it is ensured that be a closing knot in the middle of processed combination gear ring Structure.
The ultimate principle of the present invention, principal character and the present invention excellent has more than been shown and described Point.Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments, on State the principle that the present invention is simply described described in embodiment and description, without departing from the present invention On the premise of spirit and scope, the present invention also has various changes and modifications, these changes and improvements Both fall within scope of the claimed invention.Claimed scope is by appended right Claim and equivalent thereof define.
