Description

A kind of diel
Technical field
The utility model relates to a kind of diel.
Background technology
Mould is one of technological equipment realizing product production in enormous quantities.Guider is the vitals of mould, to the precision of work piece with all have material impact die life.Existing guider is generally made up of guide rod and guide pin bushing, when mold work, guide rod directly slides into the bottom of guide pin bushing when punch moves downward, make there is no buffer time when punch and die matched moulds, easily cause the wearing and tearing of mould that die life is reduced, need processing mold again, add the production cost of enterprise; In addition, guider and mould are connected as a single entity by a lot of enterprise at present, not quick detachable, when guider goes wrong, change inconvenience, affect production efficiency.
Summary of the invention
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure, and can extend the mold use life-span, the diel of easy accessibility, the utility model can save entreprise cost, enhances productivity.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of diel, comprise upper bolster, punch, die shoe, die, described upper bolster center bottom is located at by described punch, described die shoe center bottom is located at by described die, corner, described upper bolster bottom is provided with the guide rod of four arrangements that are square, described guide rod is provided with spiral groove, the kollag of heating curable on object is provided with in described spiral groove, described die shoe is provided with four and is in the guide pin bushing of coaxial line with described guide rod, can slide axially between described guide pin bushing and described guide rod and not radially wobble, spring is provided with in described guide pin bushing, the internal diameter of described spring is less than the diameter of guide rod.
When mold work, owing to slip into four guide pin bushings on corresponding die shoe at four guide rods laying respectively at upper bolster corner after, can position punch, can exactly together with die tabling.By being provided with spring in guide pin bushing, after guide rod slips into guide pin bushing, lower end of the guide rod withstands on the upper end of spring and continues to move downward, the speed that guide rod can be made under the cushion effect of spring to limit punch move downward, punch and die can not be made too quickly to be combined, avoid causing the wearing and tearing to mould because pressure is excessive, reduce die life; In the spiral groove of described guide rod, be provided with kollag can play lubrication when guide rod works, reduce the generation of wearing and tearing between guide rod and guide pin bushing, avoid strengthening the gap between guide rod and guide pin bushing, thus prevent the reduction of mould guiding accuracy and the reduction of die life.
Improve as one, described upper bolster bottom is provided with four internal threads, and described guide rod is provided with external screw thread, and described guide rod and described upper bolster are threaded connection.
The structural design that guide rod and upper bolster are threaded connection, can make guide rod and upper bolster be convenient to dismounting and maintenance.
Improve as one, described guide pin bushing comprises guide pin bushing base and guide thimble, and described guide thimble is positioned at the middle part of described guide pin bushing base, and described guide pin bushing is in T shape, and described guide pin bushing base corner is provided with bolt hole, is bolted with die shoe.
By being provided with bolt hole in guide pin bushing base corner, the structural design be bolted with die shoe, guide pin bushing and die shoe can be made to be convenient to dismounting and maintenance.
Improve as one, described spring is placed in described guide thimble bottom, and after the maximum compressibility of described spring is greater than mould matched moulds, described guide rod acts on the decrement on described spring.
After the maximum compressibility of described spring is greater than mould matched moulds, the described guide rod decrement acted on described spring can make described guide rod move in the effective travel of described spring, cushioning effect can be played, prevent mould from producing wearing and tearing, extend the mold use life-span.
Improve as one, the material of described guide rod and described guide pin bushing is spheroidal graphite cast-iron.
Spheroidal graphite cast-iron has the advantage such as good intensity, plasticity, toughness, wearability, resistance to serious heat and mechanical shock, high temperature resistant or low temperature, corrosion-resistant and dimensional stability, and guide rod and guide pin bushing adopt spheroidal graphite cast-iron to strengthen service life.
The technical solution adopted in the utility model, its beneficial effect is: 1, by being provided with the structural design of spring bottom guide thimble, guide rod can be made to slip into guide pin bushing after, under the effect of spring buffer power, punch and die can not be made too quickly to be combined, avoid producing the wearing and tearing to mould because pressure is excessive, the mold use life-span can be extended, saved entreprise cost; 2, by being provided with the structural design of kollag in the spiral groove of guide rod, lubrication can be played when guide rod works, reduce the generation of wearing and tearing between guide rod and guide pin bushing, avoid strengthening the gap between guide rod and guide pin bushing, thus prevent the reduction of mould guiding accuracy and the reduction of die life; 3, guide rod and upper bolster are threaded connection and are provided with bolt hole in guide pin bushing base corner and the structural design be bolted with die shoe, guide rod and upper bolster and guide pin bushing and die shoe can be made all to be convenient to dismounting and maintenance, improve production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is a kind of diel, comprise upper bolster 1, punch 2, die shoe 7, die 6, described upper bolster 1 center bottom is located at by described punch 2, described die shoe 7 center bottom is located at by described die 6, corner, described upper bolster 1 bottom is provided with the guide rod 3 of four arrangements that are square, described guide rod 3 is provided with spiral groove 10, the kollag of heating curable on object is provided with in described spiral groove 10, described die shoe 7 is provided with four and is in the guide pin bushing 4 of coaxial line with described guide rod 3, can slide axially between described guide pin bushing 4 and described guide rod 3 and not radially wobble, spring 5 is provided with in described guide pin bushing 4, the internal diameter of described spring 5 is less than the diameter of guide rod 3.
Described upper bolster 1 bottom is provided with four internal threads, and described guide rod 3 is provided with external screw thread, and described guide rod 3 and described upper bolster 1 are threaded connection.
Described guide pin bushing 4 comprises guide pin bushing base 8 and guide thimble 9, described guide thimble 9 is positioned at the middle part of described guide pin bushing base 8, described guide pin bushing 4 is in T shape, described guide pin bushing base 8 four jiaos is provided with bolt hole, be bolted with die shoe 7, described spring 5 is placed in described guide thimble 9 bottom, and after the maximum compressibility of described spring 5 is greater than mould matched moulds, described guide rod 3 acts on the decrement on described spring 5.
When mold work, punch 2 moves downward, guide rod 3 slips into guide pin bushing 4 until touch the spring 5 in guide pin bushing 4 under the drive of punch 2, and continue to move downward, spring 5 now plays cushioning effect, punch 2 can not be combined with die 6 too quickly, avoid producing the wearing and tearing to mould because pressure is excessive, the mold use life-span can be extended; While guide rod 3 slips into guide pin bushing 4, guide rod 3 is under the effect of spiral groove in-lubricant, the generation of wearing and tearing between guide rod 3 and guide pin bushing 4 can be reduced, avoid strengthening the gap between guide rod 3 and guide pin bushing 4, thus prevent the reduction of mould guiding accuracy and the reduction of die life.
