Abstract
The utility model discloses a composite sleeve cold upsetting die which has the exhaust structure, comprising an inner and outer cemented carbide core, a middle sleeve, an outer sleeve, a rear cushion block. The composite sleeve cold upsetting die is characterized in that the outer cemented carbide core is provided with an exhaust inclined ditch, the starting position of the exhaust inclined ditch has a certain distance with the inner diameter of the outer cemented carbide core. An outer wall of the inner cemented carbide core, the middle sleeve and the outer wall of the rear cushion block are provided with an exhaust groove. The outer sleeve and the rear cushion block are provided with an exhaust clearance for installation and combination. The exhaust inclined ditch on the outer cemented carbide core and the exhaust groove on the outer wall of the inner cemented carbide core, the exhaust groove on the middle sleeve, the exhaust clearance for installation and combination between the outer sleeve and the rear cushion block, the exhaust groove on the outer wall of the rear cushion block are communicated with each other. The distance of the starting position of the exhaust inclined ditch on the outer cemented carbide core with the inner diameter of the outer cemented carbide core is small enough, so that air can be discharged depending on the slight playing between the inner cemented carbide core and the outer cemented carbide core when the die is headed. The utility model has the advantages that the air can ensure to be exhausted from the die effectively. Thereby the using life of the die is increased. The exhaust groove is reasonable, the gripping force of a die casing is not affected, thus the die is safe. The surface quality of product is ensured, and the production cost is decreased.
Description
Technical field
The utility model belongs to technical field of mold, relates to a kind of cold-heading die, and a kind of compound cover cold-heading die with exhaust structure is provided; Be specially adapted to adopt the cold-heading manufacturing of compound nested structure die.
Background technology
In the bigger occasion of upset force, die generally adopts compound nested structure to improve the power of holding tightly of alloy, and the structure Design of the exhaust of mould is also extremely important.
Conventional composite nested structure cold-heading die comprises outer carbide alloy core, interior carbide alloy core, intermediate sleeve, overcoat, back cushion block; Exhaust structure is that the carbide alloy core is offered several the pore grooves that connect with internal diameter outside, put outward and offer several pores, gas is discharged outside the mould by these several pore grooves and the pore that puts outward, owing to offer on the outer carbide alloy core with internal diameter and connect the pore groove, cause easily that metal material enters into pore when upsetting system, thereby make the too early cracking of carbide alloy core and fall piece, put outward and offer pore, and the power of holding tightly of overcoat is reduced, also influenced the service life of mould.
Summary of the invention
The utility model discloses a kind of compound cover cold-heading die, offer on the carbide alloy core in the prior art and internal diameter connects the pore groove, the cracking that the carbide alloy core is too early and fall piece to solve with exhaust structure; Put outward and offer pore, make the power of holding tightly of overcoat problem such as reduce.
The utility model comprises outer carbide alloy core, interior carbide alloy core, intermediate sleeve, overcoat, back cushion block; It is characterized in that: have the exhaust valley on the outer carbide alloy core, outer carbide alloy core exhaust valley original position has certain spacing apart from internal diameter; Has exhaust trench on the interior carbide alloy outer core; Intermediate sleeve has exhaust trench, the intermediate sleeve exhaust trench be positioned at back cushion block contacted end face on; Has exhaust trench on the back cushion block outer wall; Overcoat is installed to cooperate with the back cushion block has exhaust clearance; The exhaust valley is connected with exhaust trench on the interior carbide alloy outer core on the outer carbide alloy core, exhaust trench is connected with the intermediate sleeve exhaust trench on the interior carbide alloy outer core, the intermediate sleeve exhaust trench is installed with overcoat, back cushion block and is cooperated exhaust clearance to be connected, and overcoat, back cushion block are installed and cooperated exhaust clearance to be connected with back cushion block outer wall exhaust trench.
Exhaust valley original position is apart from internal diameter spacing 0.2-1mm, preferred distance 0.5mm on the outer carbide alloy core of the utility model.The gap is 0.5-1.5mm between overcoat and the back cushion block, preferred gap 1mm.
The utility model intermediate sleeve and the overcoat interference fit of colding pressing; Outer carbide alloy core, interior carbide alloy core respectively with the intermediate sleeve interference fit of colding pressing; Back cushion block and overcoat hot pressing interference fit.
The utility model exhaust mechanism is as follows:
Exhaust valley original position is apart from internal diameter spacing 0.2-1mm on the outer carbide alloy core, and spacing is enough little, the moving discharge of little string when making gas can rely on the rammer system between outer carbide alloy core and the interior carbide alloy core.
Gas,, is discharged by back cushion block outer wall exhaust trench by gap between overcoat and the back cushion block by exhaust trench and intermediate sleeve exhaust trench on the interior carbide alloy outer core along exhaust valley on the outer carbide alloy core again.
The utility model advantage is: can guarantee gas discharge mould effectively; The exhaust valley does not connect with internal diameter on the outer carbide alloy core, can not enter too early the making the alloy cracking and fall piece of pore because of the porose existence of mold cavity surfaces makes metal when upsetting system; Also guaranteed simultaneously surface quality of products; Avoided intermediate sleeve and outside put punching, influence die sleeve and hold power tightly, thereby improved die life.Because of interior carbide alloy core force-bearing situation does not have outer carbide alloy core abominable, it is more reasonable to offer exhaust trench on interior carbide alloy core alloy, and safety has reduced production cost.
