Description

A kind of die steel

Technical field

The utility model is related to a kind of technical field of forging, more specifically, it relates to a kind of die steel.

Background technology

Die steel is the steel grade for manufacturing the molds such as cold-punching mould, hot-forging die, compression mod.Mold is machine-building, nothing The main machining tool of part is manufactured in the industrial departments such as line electricity instrument, motor, electric appliance.The quality of mold directly affects pressure The quality of processing technology, the precision yield of product and production cost, and the quality of mold and service life are in addition to leaning on rational knot Structure is designed with outside machining accuracy, is mainly influenced by mold materials and heat treatment.

The surface of die steel on the market is plane at present, and on the one hand die steel goes out in lorry in transportational process Existing sliding phenomenon, there are certain security risks.It on the other hand, can be by same class material when the die steel to finished product is stored Material is overlapped, and is needed to sling as the die steel on upper strata when bulk transport, be needed in hoisting process by mould steel Material lifts and passes through the rope of binding in the lower face of die steel, leverages conevying efficiency.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of difficult to slide and be conducive to remove The die steel of fortune.

To achieve the above object, the utility model provides following technical solution：A kind of die steel, including die steel Ontology.The die steel ontology be straight tetragonous rod structure, mould steel ontology include upper surface, lower face, two groups it is mutually equal Capable side sets two groups of grooves on the upper surface, and every group of groove is made of several grooves, the number of the two group groove Mesh is equal, and is all mutually parallel between groove, and the cross sectional shape of each groove is triangle；In the lower face Two groups of tongues are provided with, every group of tongue is made of several tongues, and the number of every group of tongue is identical and equal to every group of groove Number, parallel to each other between tongue, tongue is arranged in parallel with groove；The cross sectional shape of the tongue is triangular form, and size Shape is identical with the triangle of groove section shape.The tongue can play the role of anti-skidding between ground；Described is recessed Slot is adapted with tongue, plays the superimposed function of difference mould steel of same model, and is avoided that two moulds after superposition There is the imagination slided in tool steel.

End face edges at two ends in the upper surface and lower face is respectively arranged with an arc groove, the arc groove Cross sectional shape is parallel to each other between the arc groove to be semicircle, and is arranged in parallel with groove.And the difference of same model Mould steel, which is stacked, to be added together enough, and the arc groove of upper surface can be overlapped with the arc groove of lower face, is formed a cylinder and is led to Hole.By arc groove, can in the case where not lifting die steel to one or same layer in multiple mould steel carry out Binding.

There are one fillets with setting on the transition part I of upper surface for the groove face I of the groove.The slot bottom setting of the groove There is fillet, chamfering is provided on the transition part II of the groove face I of the adjacent groove of each two.The groove top of the tongue is provided with circle Angle is provided with fillet, and the size of the fillet of groove top part on the groove formed between the two neighboring tongue groove face II More than the fillet on slot hook part point.By using said program, it can reduce in die steel additive process, groove and tongue knot The phenomenon that conjunction is collided with.

Compare the deficiencies in the prior art, advantageous effect caused by technical solution provided by the invention：The mould steel The upper surface of material is respectively provided with groove and tongue, and the tongue can play the role of anti-skidding, described groove and mutually be fitted with tongue Match, can realize being overlapped mutually and being not in slide for two mould steel；And arc groove is provided with, be conducive to restrict in handling process The binding of rope.

Specific embodiment

One embodiment of the utility model is described further referring to figs. 1 to Fig. 3.

A kind of die steel, including die steel ontology.The die steel ontology can be square or rectangular Body.Mould steel ontology includes upper surface 1,2, two groups of lower face side parallel to each other, and two groups are set on the upper surface Groove 4, the number of two groups of grooves 4 is equal, and the number of every group of groove 4 can be 5, and be all mutually parallel between groove 4；Institute The cross sectional shape of each groove 4 stated is triangle.Two groups of tongues are provided on the 4 corresponding lower face 2 of groove 5, the number of two groups of tongues 5 is identical and is equal to the number of groove 4；It is parallel to each other between tongue 5, and tongue 5 is parallel with groove 4 sets It puts, the cross sectional shape of the tongue 5 is triangular form, and size shape is identical with the triangle of 4 cross sectional shape of groove；Described Triangle is isosceles triangle, and the apex angle size of triangle is 50 °.The tongue 5 can rise between die steel and ground To anti-skidding effect；The groove 4 is adapted with tongue 5, plays the superimposed function of difference mould steel of same model, again It is avoided that the imagination slided occur in two die steels after superposition.

End face edges at two ends in the upper surface 1 and lower face 2 is respectively arranged with an arc groove 6, the arc 6 cross sectional shape of shape slot is parallel to each other between the arc groove 6 to be semicircle, and is arranged in parallel with groove 4.And same model Difference mould steel be stacked and be added together enough, the arc groove 6 of upper surface 1 can be overlapped with the arc groove 6 of lower face 2, be formed One cylindrical hole.It, can be in the case where not lifting die steel in one or same layer by setting arc groove 6 Multiple mould steel are bundled.

There are one fillets with setting on the transition part I 3 of upper surface 1 by I 4a of groove face of the groove 4.The slot of the groove 4 Bottom 4b is provided with fillet, and chamfering is provided on II 4c of transition part of I 4a of groove face of the adjacent groove 4 of each two.The transition The difference in height that II 4c of portion 4bs low with slot is formed is L1, and the low 4b of the slot and the difference in height that upper surface 1 is formed are L2, and L1 ＜ L2.The groove top 5c of the tongue 5 is provided with fillet, the groove formed between II 5b of groove face of the two neighboring tongue 5 Fillet is provided on 5a, and the size of the fillet of groove top 5c parts is more than the fillet on slot hook 5a parts.The groove top 5c with The difference in height that lower face 2 is formed is L3, and L2=L1.By using said program, can reduce in die steel additive process Groove 4 is combined the phenomenon that colliding with tongue 5.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field Art personnel carry out common variations and alternatives in the range of technical solutions of the utility model should all be included in the guarantor of the utility model In the range of shield.
