Description
Technical field
The present invention is applicable to the assembling of aluminum star pipe heat exchange vaporizer in mechanized equipment manufacturing air separation equipment.
Background technology
Aluminum star pipe heat exchange vaporizer is often applied to the heat vaporized of cryogenic liquid in air separation equipment, is utilize the cryogenic liquid in the heat vaporized heat exchanger tube of natural convection air.This kind of heated vaporizer is when cryogenic liquid passes through in heat exchanger tube, and use normal temperature air as heat medium, operating cost is cheap, is therefore widely used in air separation plant.
Four fin muscle of aluminum star-shaped heat exchange tube 1 penetrate in four retainer fixed card slots, and up and down, left and right to be alternately arranged layout, and star-shaped heat exchange tube and aluminum retainer 2 to be fixed at draw-in groove place.Again UNICOM is carried out on request in the central tube two ends of star-shaped heat exchange tube, thus composition star heat exchange of heat pipe.
Past star-shaped heat exchange tube adopts spot welding to fix at retainer draw-in groove place.Use compression bonding method star-shaped heat exchange tube and retainer to be fixed, make the assembly work of star heat exchange of heat pipe more convenient.This instrument is these needs of adaptation and invents.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art provides one more convenient, high efficiency aluminum star pipe to assemble Press Plier.
Technical scheme of the present invention is achieved in that a kind of aluminum star pipe assembling Press Plier, this Press Plier comprises hydraulic cylinder, oil cylinder seat, loose joint, tong arm seat, tong arm and pressure head, described hydraulic cylinder is single-piston rod double acting hydraulic cylinder, the front end external screw thread of described hydraulic cylinder is connected and fixed described oil cylinder seat, described oil cylinder seat is symmetrical up and down, front end arranges two holes, described holes respectively by a hole of a hinge described loose joint, the right-hand member hole of the hinged described tong arm in another hole of described loose joint; The piston rod front end external screw thread of described hydraulic cylinder is connected and fixed described tong arm seat, and described tong arm seat is symmetrical up and down, and two holes are offered at middle part, and described holes respectively uses the interstitial hole of tong arm described in hinge; Described tong arm front end offers T-slot, loads described pressure head in groove, and described pressure head is symmetrical, and two holes are respectively offered in both sides, can penetrate finer wire, break curved by finer wire two ends, in order to avoid deviate from.
The good effect that technical scheme of the present invention produces is as follows: 1. improve Product Assembly presentation quality, and when adopting welding procedure, spot size, shape differ, affect product appearance quality, when adopting compression joint technique, impression is in the same size, and product appearance quality is improved a lot; 2. cancel welder's work post when assembling, reduce cost of labor, when former cold working is assembled, need star pipe to weld with retainer, need welder to coordinate, by cold working and welder's alternately operating.When adopting compression joint technique, assembling, crimping work are completed separately by cold working, cancel welder, reduce cost of labor; 3. crimping is more convenient for operating than welding, and it is very narrow and small that star pipe and retainer assemble rear operating space, and during welding, not only electrode holder reaches welding position, also needs to put in welding rod, operate very difficult, the clamp specially of design, simple to operate, better can adapt to small space, it is relatively convenient to operate; 4. relatively weld, after crimping there is not tissue change in material, and product keeps stable mechanical performance and corrosion resistance.

Detailed description of the invention
A kind of aluminum star pipe assembling Press Plier, as shown in Fig. 1 to 11, this Press Plier comprises hydraulic cylinder 4, oil cylinder seat 5, loose joint 6, tong arm seat 7, tong arm 8 and pressure head 9, described hydraulic cylinder is single-piston rod double acting hydraulic cylinder, the front end external screw thread of described hydraulic cylinder is connected and fixed described oil cylinder seat, and described oil cylinder seat is symmetrical up and down, and front end arranges two holes, described holes respectively by a hole of a hinge described loose joint, the right-hand member hole of the hinged described tong arm in another hole of described loose joint; The piston rod front end external screw thread of described hydraulic cylinder is connected and fixed described tong arm seat, and described tong arm seat is symmetrical up and down, and two holes are offered at middle part, and described holes respectively uses the interstitial hole of tong arm described in hinge; Described tong arm front end offers T-slot, loads described pressure head in groove, and described pressure head is symmetrical, and two holes are respectively offered in both sides, penetrate finer wire 3, break curved by finer wire two ends, in order to avoid deviate from.
Comparatively carry out crimping work in narrow space for guarantee instrument can be deep into, the little as far as possible of shelves design is opened in the front end (left end) of two tong arms, and pressure head and tong arm adopt simple T-slot to coordinate; Adopt finer wire to prevent pressure head from skidding off in the T-slot of tong arm front end, the gauge of tool tong port part can be effectively reduced.Pressure head can design differing heights size and meet different product requirement.During tong arm design internal arm, after ensureing clamping work pieces, tong arm inner edge with outside star pipe clamp groove is not interfered; During tong arm design outside width, need to ensure no matter clamp is in clamping or unclamps any state and all can not interfere with other positions of workpiece; Need to carry out bending strength during tong arm design, deflection is checked, after ensureing that compression is stressed, pressure head position elastic deformation amount is not more than 0.15mm, and determines the gauge of tong arm accordingly.
Instrument needs outfit small-sized hydraulic station, is connected with the oil out port that enters of hydraulic cylinder with sufficiently long hydraulic hose.
The external diameter of hydraulic cylinder is not more than 50mm, so that as the handgrip part of instrument.For ease of operation, oil circuit gauge tap is arranged in the afterbody of hydraulic cylinder.
During the oil-feed of hydraulic cylinder rodless cavity, piston rod stretches out, and produces thrust; During the oil-feed of hydraulic cylinder rod chamber, piston rod is retracted, and produces pulling force.Affect by piston rod, in oil pressure one timing, the thrust that piston produces is greater than pulling force.Therefore consider when Press Plier designs, make instrument pressure head to middle shrinkage workpiece pressing when piston rod produces thrust, now system can produce larger crimp force with less oil pressure.
Fig. 5 is pressure head releasing orientation, during crimping, the oil-feed of hydraulic cylinder rodless cavity, piston rod stretches out, and the relative tong arm seat of oil cylinder seat moves right (distance increases), and the right-hand member bearing pin that loose joint promotes tong arm outwards opens, tong arm rotates around middle bearing pin, drive the pressure head of left end to move to centre, reach state shown in Fig. 4, complete the crimping to workpiece.Crimping completes, the oil-feed of hydraulic cylinder rod chamber, and the relative tong arm seat of oil cylinder seat is to left movement (distance reduces), loose joint pulls the right-hand member bearing pin of tong arm inwardly to shrink, and tong arm rotates backward around middle bearing pin, drives the pressure head of left end outwards to open, when reaching state shown in Fig. 5, Press Plier unclamps.It is more than the crimping process of a tie point.
Fall head size crimps the degree of depth by star pipe clamp groove and determines.The crimping degree of depth is managed pulling-out force required between retainer by star and is determined, the size of pulling-out force determines the bonding strength of product.Facts have proved, for ensureing that star heat exchange of heat pipe has reliable bonding strength and job stability, different according to the factor such as small product size, quality, the depth of cup of star pipe clamp groove requires between 3-5mm, thus can the height dimension of design head.
