Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the utility model hot forming water cooling mold structural representation, and as shown in Figure 1, the bed die that the mould of the present embodiment comprises mold and mates with described mold shape and size, comprising:
Described mold 101 is provided with electrically heated rod putting hole 102, described mold die shank 103 is connected with press, described bed die is spliced by least two inserts 104 and is connected with backing plate 105, described at least two inserts 104 inside is provided with the cooling water channel 106 of Cooling Water flowing, and described water channel interface is provided with seal groove 107, described in sealing, between at least two inserts 104, the sealing ring 108 of water channel interface is placed in described seal groove 107.
Specifically, the hot forming water cooling mold in the present embodiment comprises mold and bed die, and the die shank of this mold is connected with press, is provided with electrically heated rod putting hole.The heating-up temperature of this mold is regulated by temperature control box.And adopt asbestos insulation between press baffle plate.Bed die is spliced by two inserts and is connected with backing plate, in the present embodiment, two inserts adopt tools for bolts ' pretension, the cooling water channel of Cooling Water flowing is provided with in two inserts, this water channel interface is provided with seal groove, sealing ring is placed in sealing ring recess, sealing circle is high temperature resistant O RunddichtringO, comprises and comprises fluorosioloxane rubber sealing ring, FFKM sealing ring, brass washer and bonded washer etc.Mould in the present embodiment, the water circulation system of bed die can be supplied by outer water system, and when the cooling water channel that water circulation system is two insert inside provides cooling water, this cooling water flows into from one end of two splicing inserts, and the other end directly flows out.Water circulation system can control current size by regulating pump rotary speed.
Performance Detection for the mould of the present embodiment can have following process: whole set of die is fixed on high speed hydraulic press, and at seal groove assembling variable color test paper, two insert splicing planes place very thin chance water variable color test paper, this variable color test paper is made into the size and dimension identical with mating surface, circular ring type can be met water variable color test paper and be fixed on seal groove surrounding, the size of inner circle is identical with seal groove size.In seal groove, mold face, bed die face and two insert stitching portions arrange thermocouple, and as shown in Figure 2, thermocouple is 301, and insert is 302.Warm galvanic couple is adopted in upper die face welding, and mold face heating-up temperature is regulated by temperature control box, makes mold surface temperature be stabilized in set temperature, the heat that during approximate simulation drop stamping, plate produces.Place the groove interior layout thermocouple of sealing ring, monitoring sealing ring invalid temperature.Gather flowing water temperature, sealing ring surface temperature, stitching portion mold temperature between die face temperature and two cooling water channels in cooling water channel respectively.As shown in Figure 3, start water circulation system 401 and temperature control system 402, the temperature of mold is provided by electrically heated rod, and testing press is 40T high-speed hydraulic press; By press ON cycle pattern, the dwell time of setting punching press number of times and each punching press and idle hours, according to hot forming high strength steel productive temp, generally setting each circulation timei is 20 seconds, and wherein pressurize is 15 seconds, and cycle-index is more than 50 times.Mold adopts large power, electrically heating tube to carry out heating and the real-time thermocouple by being welded on die surface gathers the mold face temperature in heating process, and bed die cooling medium is water.In order to reduce the impact of cooling water channel prolongation on cooling effect, in cooling water, add cold-producing medium.The parameters such as cycle-index, dwell time and mold heating-up temperature can be detected by PC setting, after cycle-index terminates, water remaining in counterdie water channel is dried up, taking out variable color test paper, observe variable color area, by dividing flower pattern grid, variable color area can be quantized.Shown in Fig. 4,501 is taint-free test paper area, and 502 is the test paper area of variable color.When variable color area is greater than 70% in the present embodiment, then be defined as the Mosaic face infiltration between two inserts, if variable color area is less than 70%, then the Mosaic face be defined as between two inserts does not seep water, and improves the heating-up temperature of mold until the variable color area of variable color test paper is greater than 70%.Record cycle-index corresponding to temperature corresponding to temperature control system when described variable color test paper variable color area is greater than threshold area, described water circulation system and described sealing ring model.Change sealing ring kind, the step of above-mentioned detection method carries out the Performance Detection of mould again, and the parameters that the sealing ring recording this model is corresponding.Mold arrangement sealing ring is recorded as according to this.Be illustrated in figure 5 typical seal groove place temperature curve variation diagram.Temperature curve obtains for the seal groove place thermocouple shown in Fig. 2 in 301.Under state of cyclic operation, temperature curve shows as fluctuation-type and rises, until be stabilized in rational operation threshold.The working temperature typical upper limit is at 55-65 DEG C, and lower limit is 30-40 DEG C.
The present embodiment, whether threshold area is greater than by the variable color area of variable color test paper, and the temperature that temperature control system is corresponding, judge whether to seep water between bed die two inserts and record corresponding temperature, thus determine the model of the sealing ring that hot forming water cooling mold mates, achieve the detection of mould sealing property, improve the yield rate of Mould Machining.
The present embodiment, between horizontally-spliced structure hot forming water cooling mold at least two inserts, water channel directly seals splicing, the water flowing thus the cooling water channel between each insert is directly connected, do not need additionally to arrange tank to make the independent Inlet and outlet water of each insert, increase water-cooled area in each insert, make the mechanical performance of processing parts more even, stable.While simplifying mould structure, also improve the mechanical performance of processing parts, reduce Mould Machining cost, improve the sealing effectiveness of mould, improve the yield rate of mould.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
