The high-pressure oil pipe connector cold pressing die comprises a portal frame, a die block and a jack, wherein the portal frame is composed of four steel channels, the die block is composed of an upper half block and a lower half block which are identical in size and shape, and the upper half block and the lower half block are respectively provided with a groove. The upper half block is fixed below a top beam of the portal frame, the jack is fixed on the floor beam of the portal frame, the lower half block is fixed at the top end of the jack, and steel plate reinforcing ribs are welded in the steel channels of the top beam and the floor beam of the portal frame. The high-pressure oil pipe connector cold pressing die used for the diesel engine is simple in structure, convenient to manufacture and install, small in material utilization amount and investment, easy and convenient to operate, high in repair accuracy, good in quality, capable of completely meeting use conditions, safe and practical and saves capital.
Description
Technical field:
The utility model relates to the flight-line maintenance field, particularly a kind of cold stamping die for the high-pressure oil pipe joint maintenance.
Background technology:
Along with the increasing that China drops into hydraulic engineering, the construction of hydro project task is heavy all the more, and the engineering machinery of purchasing is also more and more.The engineering machinery major part is the high-pressure oil pipe operation, and in engineering construction, the phenomenons such as seepage, explosion, pull-off often occur mechanical high-pressure oil pipe joint.Once above-mentioned situation occurs, will SDR.Mechanical execution team does not have to repair specially the instrument of high-pressure oil pipe, and general county town is also the retail sales that special repairing high-pressure oil pipe is seldom arranged, and generally will arrive the above city of city-level and go for the retail sales pressuring oil pipe joint of repairing specially high-pressure oil pipe.Building site, particularly hydraulic engineering, be all in remote area construction mostly, all distant from city.Once engineering machinery high-pressure oil pipe generation problem, few side a couple of days, many sides just can be fixed in three or four days.Not only economy causes waste, and delays the engineering time.For high-pressure oil pipe is repaired in time, economize on the use of funds, go into operation in time.We conscientiously study the pressing principle of high-pressure oil pipe joint according to actual conditions, through test of many times, improve, and have successfully developed the high-pressure oil pipe joint cold stamping die.This high-pressure oil pipe joint cold stamping die has solved the pressure pipe difficulty, has saved the economic loss caused because of pressure pipe, for the time has been striven in construction.
Summary of the invention:
Technical solution adopted in the utility model is as follows:
A kind of high-pressure oil pipe joint cold stamping die, comprise portal frame, mould piece and jack, described portal frame is made by four channel-section steels, described mould piece is comprised of upper half block and lower half block, described upper half block is identical with the size and shape of lower half block, on described upper half block and lower half block, a groove is respectively arranged, wherein, described upper half block is fixed on the back timber bottom of described portal frame, described jack is fixed on the bottom girder top of described portal frame, described lower half block is fixed on the top of described jack, in the channel-section steel of the back timber of described portal frame and bottom girder, is welded with the steel plate reinforcement.
Diesel engine high-pressure fuel conduit joint cold stamping die of the present utility model, simple in structure, fabrication and installation are convenient, and material usage is few, invests lowly, simple to operation, repairs precision high, and quality is good, can meet service condition fully, economizes on the use of funds, safe and practical.
The accompanying drawing explanation:
Fig. 1: the elevation of diesel engine high-pressure fuel conduit joint cold stamping die of the present utility model.
Fig. 2: the mould piece elevation of diesel engine high-pressure fuel conduit joint cold stamping die of the present utility model.
Fig. 3: the lower half block top view of diesel engine high-pressure fuel conduit joint cold stamping die of the present utility model.
In figure, 1 is portal frame, and 2 is the mould piece, and 3 is jack, and 4 is upper half block, and 5 is lower half block, and 6 is groove.
The specific embodiment:
As shown in Figure 1-Figure 3, diesel engine high-pressure fuel conduit joint cold stamping die of the present utility model, comprise portal frame 1, mould piece 2 and jack 3, described portal frame 1 is made by four channel-section steels, described mould piece 2 is comprised of upper half block 4 and lower half block 5, described upper half block 4 is identical with the size and shape of lower half block 5, the hole that respectively has 6, two grooves 6 of a groove to be combined on described upper half block 4 and lower half block 5 to form a shape with the diesel engine high-pressure fuel conduit joint to be complementary; Wherein, described upper half block 4 is fixed on the back timber bottom of described portal frame 1, and described jack 3 is fixed on the bottom girder top of described portal frame 1, and described lower half block 5 is fixed on the top of described jack 3.In order to increase the rigidity of portal frame 1, reduce strain, be welded with the steel plate reinforcement in the channel-section steel of the back timber of described portal frame 1 and bottom girder.
Mould piece used of the present utility model is that the bloom car system a little less a little with two overall diameters with the high-pressure oil pipe pipe forms, and plays the effect of joint typing and extruding.The mould of size that should be different by the large dolly system of different high-pressure oil pipe joint diameters, used in order to check the number.The mould block of material can add man-hour first that the blank of the briquetting mold up and down stack of having dug is neat with No. 45 steel, and four angle points welderings are got on the bus after making and removed spot welding at lathe.Half-and-half separately modify corner angle with chisel, gauze etc. again, finally quench, hardness reaches HRC45-50 and gets final product.Utilize a 8t jack pair high-pressure oil pipe joint to be withheld reparation.Portal frame 1 adopts No. 45 channel-section steel welding, is shaped as rectangle, specifically is of a size of: long 40 centimetres; Wide 30 centimetres.
During reparation, joint is cut together with oil pipe explosion part, take out available connecting pin mother and pull head core.Repair or the self-control fitting sleeve, press original structure assembling moulding, insert in the mould piece, be fixed on portal frame 1 and jack 3, with jack, withhold locking.Withhold and part carry out for twice, after withholding for the first time, oil pipe is turned over after turning 90 degrees and withholds once and get final product again together with joint.
Up to now, utilize altogether this instrument to repair little Song excavator high-pressure oil pipe pipe 11 times, vibrating roller high-pressure oil pipe pipe 16 times, scraper high-pressure oil pipe pipe 89 times, all can meet design requirement, and the quality and performance of the high-pressure oil pipe pipe through repairing all meets instructions for use.Considerable economic worth and social benefit have been obtained.
