Abstract
The invention discloses a water cooling mold for high-strength steel plate stamping part thermal forming. A casting type water chamber open pore structure is used, the cost is low, the effect is good, and cooling faces and mold faces are consistent completely. The mold comprises upper and lower mold plates, mold inserts, a guide unit and a location unit. Water chamber pore opening is performed on the mold inserts through a casting method. Large water chambers, water inlet chambers and water outlet chambers are cast in the mold inserts. A plurality of communication holes are formed between the water inlet chambers and the large water chambers and between the large water chambers and the water outlet chambers. The camber shapes formed by the upper surfaces of the large water chambers, the water inlet chambers and the water outlet chambers are consistent with the shape of the mold surface. Transverse rib plates and longitudinal rib plates are arranged in the large water chambers to divide the large water chambers into a plurality of small water chambers, and a plurality of communication holes are formed in the transverse rib plates.
Description
Technical field
The present invention relates to a kind of water cooling mold, be specifically related to the cold mould of a kind of high strength steel plate stamping parts thermoforming industrial water, belong to compression molding technology.
Background technology
The shaping high strength steel plate part of tide of motorism is widely used, and it is current automotive light weight technology optimal path.There is multiple country can produce this transfer matic in the world, external transfer matic major part of producing is continuous tunnel furnace heating at present, temperature when part takes out in stove is at about 850 DEG C, the press diel that runs to through 2-3 second has cooled to about 780 DEG C, at this moment part metallographic is austenite, and from about 730 DEG C time, austenite is to martensite transfor mation, and the time shorter martensitic conversion ratio of this section of cooling is higher, require martensitic structure more than 95%, therefore cooling is not all right naturally.
As shown in Figure 1, to water cooling mold external at present the scheme of employing add cooling water channel in a mold, namely on die insert, processes some through holes with depth drill, make current pass through to cool.During actual compression molding, most part is all space curved surface, but adopt the mode of boring can not bore curved slot in insert, when therefore adopting the insert of this form, die face boring can only be pressed close to as far as possible when ensureing mould strength, water channel can not cause mold cools down uneven, price is high uniformly near die face, water-cooled weak effect.
Summary of the invention
The invention provides the cold mould of a kind of high strength steel plate stamping parts thermoforming industrial water, adopt cast type hydroecium open-celled structure, cost ineffective fruit is good, cooling surface and die face completely the same.
The object of the invention is to be realized by following scheme, by reference to the accompanying drawings:
The cold mould of a kind of high strength steel plate stamping parts thermoforming industrial water, comprise bolster, die insert, guider, positioner, die insert adopts cavityless casting method to carry out hydroecium perforate, large hydroecium, intake chamber and water-supplying chamber is cast with, between intake chamber and large hydroecium and greatly between hydroecium and water-supplying chamber, some intercommunicating pores are all set in die insert; Large hydroecium, intake chamber are consistent with die face shape with the curve form of water-supplying chamber's upper surface formation.
The described cold mould of a kind of high strength steel plate stamping parts thermoforming industrial water, wherein, flood indoor are provided with horizontal gusset and longitudinal gusset, and flood interventricular septum is become multiple little hydroecium, and horizontal gusset is provided with some intercommunicating pores.
The described cold mould of a kind of high strength steel plate stamping parts thermoforming industrial water, wherein, die insert inclined 8-10mm in die face casts each hydroecium.
Compared with existing access tunnel stove formula thermoforming transfer matic, the present invention has the following advantages:
The water cooling mold that the present invention adopts adopts cast type hydroecium open-celled structure, and cost ineffective fruit is good, cooling surface and die face completely the same.
Contrast with external water cooling mold, price reduces by 70%, and water-cooled effect improves greatly.
The thermoforming of high strength steel plate stamping parts is produced and is adopted water cooling mold of the present invention, with die trimming after cold forming, enter hot shaping quenching process again, save laser cutting, and not needing import equipment to save external labour cost, the high-strength plate auto parts cost that thermoforming Automatic production line of the present invention is produced can reduce 25-40%.

Detailed description of the invention
Technical scheme of the present invention is introduced in detail below in conjunction with accompanying drawing.
Water cooling mold provided by the invention is used for high strength steel plate stamping parts thermoforming Automatic production line, as shown in Figure 3, Automatic production line comprises pay-off 1, quick-replaceable blade wheel shaft type heating furnace 2, lower transmission parts device 3, upper transmission parts device 4, high speed press 5 and the pick-off unit 7 arranged successively, is provided with water cooling mold 6 in high speed press 5; Workpiece is sent into quick-replaceable blade wheel shaft type heating furnace 2 and is carried out high-temperature heating by pay-off 1, workpiece after heating takes out by lower transmission parts device 3 in quick-replaceable blade wheel shaft type heating furnace 2, upper transmission parts device 4 is arranged in above lower transmission parts device 3, be sent to high speed press 5 after its workpiece grabbing taken out by lower transmission parts device 3 and carry out die mould, the workpiece after high speed press 5 die mould takes out and is passed to conveyer and carries by pick-off unit 7.
The cold mould of high strength steel plate stamping parts thermoforming industrial water provided by the invention, it is roughly the same with the structure of common diel, be made up of bolster, guider, positioner etc., just the punch-die insert of working portion needs to add cyclic water channel, to cool rapidly the object that workpiece reaches quenching.Water cooling mold insert of the present invention adopts cavityless casting to carry out hydroecium perforate, involved water cooling mold insert NC Milling is become casting bubbles model, as shown in Figure 2, by digital-to-analogue, 8-10mm inclined in die face is cast large hydroecium 61, again by large hydroecium 61 as required between be separated out intake chamber 62 and water-supplying chamber 63, and between intake chamber 62 and large hydroecium 61 and greatly some intercommunicating pores 66 are all set between hydroecium 61 and water-supplying chamber 63, to reach the water circulation in hydroecium.Again according to mould stressing conditions, by arranging horizontal gusset 64 and longitudinal gusset 65 in large hydroecium 61, large hydroecium 61 is partitioned into multiple little hydroecium, longitudinal gusset 65 need not open intercommunicating pore, horizontal gusset 64 opens some intercommunicating pores 66, to ensure water circulation path.The curve form that each hydroecium upper surface is formed is consistent with die face shape, and namely the cooling surface of die insert is consistent with die face shape.Seal groove 67 is arranged with outside hydroecium.Mould uses high alloy forging die steel, has high heat-resisting, fatigue durability, and has surface hardening function, and after quenching, workpiece does not deform.Through the trial-production to several part water cooling mold, the water cooling mold cooling effect that the present invention adopts is splendid.After insert casting, by digital-to-analogue machine-shaping on numerical control mill, then pincers worker refine polishing, assembles.
