Description
Technical field
The present invention relates to mould, be specifically related to a kind of large automobile connecting rod edge-cutting and hole-punching correcting combined die.
Background technology
Along with the development in epoch, people's rhythm of life is more and more faster.Demand as the core component connecting rod of locomotive engine is increasing.Engine connecting rod is the core component of engine, and the quality of connecting rod directly affects the life-span of engine.Present Domestic engine connecting rod is mostly processed to realize from external import or by entirety.Thereby the Forging Technology of connecting rod plays key effect to its quality.
At present, in the manufacturing process of engine connecting rod, connecting rod is after forging, need to carry out to it operations such as trimming, punching, correction, aforesaid operations is generally to realize by the overall compound die of trimming, punching, correction, or forging first returns on forcing press and proofreaies and correct again after trimming, and aperture gas cutting or machined complete.The tool structure complexity of the former overall compound die, equipment limitation is large, is applicable to small-sized connecting rod, inapplicable for Design of Large & Medium Connecting Rod; The latter's operation is many, complex operation, and production efficiency is low, has caused the increase of processing cost.Owing to there are the problems referred to above, need urgently a kind of new processing technology, solve the problem that above-mentioned two kinds of technology exist, thereby make the manufacturing procedure of connecting rod few, working (machining) efficiency is high.
Summary of the invention
The object of this invention is to provide a kind of large automobile connecting rod edge-cutting and hole-punching correcting combined die, solve one or more problem in above-mentioned prior art.
A kind of large automobile connecting rod edge-cutting and hole-punching correcting combined die, it is characterized in that, comprise: trimming cope match-plate pattern, trimming upper male mould, upper male mould backing plate, pull bar, U-shaped plate, trimming lower punch, the first drift die shank, the first drift, lower punch supporting plate, the second drift die shank, the second drift, trimming die holder, guide pillar, the first drift die shank is connected with trimming die holder base plate with the second drift die shank, trim die connects trimming upper male mould in trim die base and is connected with upper male mould backing plate, and pull bar is connected with U-shaped plate.
Red heat forging through die forging is placed on trim die, the top shoe of press is descending, drive trimming upper male mould descending, cut the gross weight in overlap and the hole of forging, continue descending, by trimming upper male mould and trimming lower punch, forging is proofreaied and correct, proofreaied and correct that to finish on rear press slide the moving pull bar of shipper pole up, take out forging, whole release, completes a working cycles.
Beneficial effect of the present invention is: the deficiency that solves shop equipment, save manpower, a kind of composite die that forges trimming, punching, correction of increasing work efficiency, with this trimming Correction Die, on an equipment, complete and needed three work that equipment completes, improve operating efficiency, alleviated workman's labour intensity, reduced the production cost of product.
Brief description of the drawings
Fig. 1 is the structural representation of the large automobile connecting rod edge-cutting and hole-punching correcting combined die of one embodiment of the present invention.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
The invention provides a kind of large automobile connecting rod edge-cutting and hole-punching correcting combined die, as shown in Figure 1, comprise: trimming cope match-plate pattern 1, trimming upper male mould 2, upper male mould backing plate, pull bar 4, U-shaped plate 5, trimming lower punch 8, the first drift die shank 9, the first drift 10, lower punch supporting plate 11, the second drift die shank 12, the second drift 13, trimming die holder 14, guide pillar 15, the first drift die shank 9 is connected with trimming die holder 14 base plates with the second drift die shank 13, trim die connects trimming upper male mould 2 in trim die base and is connected with upper male mould backing plate, and pull bar 4 is connected with U-shaped plate 5.
A kind of large automobile connecting rod edge-cutting and hole-punching correcting combined die using method:
The first drift 10 die shanks 9 are connected with trimming die holder 14 base plates by bolt with the second drift 13 die shanks 12, and trim die connects in trim die base;
Trimming upper male mould 2 is connected with upper male mould backing plate 3, and pull bar 4 is connected with U-shaped plate 5;
Mould matched moulds, is installed on mould on friction press, regulates press stroke, ensures that closed height is less than 1070mm;
On guide pillar 15, add adjusting backing plate, make trimming upper male mould 2 enter interior 20 millimeters of trim die;
Adjust the nut on press stroke and pull bar 4, make trimming lower punch 8 before trimming, exceed trim die, conveniently put into forging and be advisable;
Red heat forging through die forging is placed on trim die, the top shoe of press is descending, drive trimming upper male mould 2 descending, cut the gross weight in overlap and the hole of forging, continue descending, by trimming upper male mould 21 and lower punch 8, forging is proofreaied and correct, proofreaied and correct that to finish on rear press slide the moving pull bar 4 of shipper pole up, take out forging, whole release, completes a working cycles.
Beneficial effect of the present invention is: the deficiency that solves shop equipment, save manpower, a kind of composite die that forges trimming, punching, correction of increasing work efficiency, with this trimming Correction Die, on an equipment, complete and needed three work that equipment completes, improve operating efficiency, alleviated workman's labour intensity, reduced the production cost of product
More than statement is only optimal way of the present invention, it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, within these also should be considered as protection scope of the present invention.
