Technical field
The present invention relates to cylinder for liquefied gas welding technology field, be specifically related to a kind of weld jig of base of liquefied gas steel cylinder.
Background technology
Cylinder for liquefied gas is used to store the storage bottle of liquefied gas, and when there is a liquefied gas its inside, pressure is very large, and slightly misoperation just likely sets off an explosion, and liquefied gas is 0.8 MPa at 20 deg. C Pressure, and the pressure of 40 degrees Celsius can reach 1.59 MPas.The maximum pressure that bears of cylinder for liquefied gas is 2.1 MPas.If volume of liquefied gas is constant, temperature often raises 1 deg. C Pressure just increases by 0.04 MPa, so every steel cylinder can only fill with 85%, and namely 14.5 kilograms.Also do not heat steel cylinder with warm water when empty bottle, otherwise can physical explosion be caused.
Cylinder for liquefied gas is II type III pressure vessel of the inflammable and explosive chemicals of splendid attire, is widely used in living standard of urban and rural population and in the street restaurant in cities and towns, a slap-bang shop and cafe.The welding quality of base of liquefied gas steel cylinder determine steel cylinder filling, carry and stability in use procedure.
The production process of base is: shearing blanking, press-bending (or roll bending) become straight tube shape, welding opposite side.Welding opposite side is the important procedure manufacturing base, and the efficiency of welding directly determines the production cost of base.Plate creates resilience in press-bending or roll bending deformation process, and this resilience makes two limits that will weld not contact, and there is certain extended distance, and measure must be adopted during welding to make opposite side extended distance be reduced to designated value or opposite side coincidence.The extended distance using the method for worm drive to eliminate straight tube shape opposite side in most cylinder for liquefied gas manufacturing enterprise reaches welding condition; there is operation inconvenience in this method; waste time and energy, the shortcomings such as production efficiency is low, other technologies all cannot meet the needs of large-scale production.

Detailed description of the invention
In order to have a clear understanding of technical scheme of the present invention, its detailed structure will be proposed in the following description.Obviously, the concrete execution of the embodiment of the present invention also not enough specific details being limited to those skilled in the art and haveing the knack of.The preferred embodiments of the present invention are described in detail as follows, and except these embodiments described in detail, can also have other embodiments.
From Fig. 1 ~ Fig. 5, the present invention it comprise clamp body 1, magnetic suction disc 2, folder lid 3, guiding screw pole 4 and back-moving spring 5, the plane of described clamp body 1 offers semicircular lower locating slot 11, the bottom of described lower locating slot 11 is provided with protection mouth 15, the left side of lower locating slot 11 offers hanger groove 13, the rear and front end of hanger groove 13 is provided with rotates pin-and-hole 14, and the right side of lower locating slot 11 is provided with spring nest groove 12, is provided with back-moving spring 5 in described spring nest groove 12; The right-hand member of described clamp body 1 is provided with magnetic suction disc 2, and the side of described magnetic suction disc 2 is provided with sucker driving switch 21; One end of described folder lid 3 is provided with adhesive platform 31, and the other end is provided with hanger 34, and centre is provided with locating slot 33, and the right side of described upper locating slot 33 is provided with pilot hole 32; Described clamp body 1 is by hanger 34 and rotate the rotational pin 7 and folder lid 3 chain connection that are provided with in pin-and-hole 14; One end of described guiding screw pole 4 is fixed on immediately below spring nest groove 12, and the other end is provided with stop nut 6 through after back-moving spring 5 and pilot hole 32.
Using method of the present invention is: first straight tube 8 before base weldering be placed in lower locating slot 11, make left side 81 and right side 82 be in immediately below lower locating slot 11; Be rotated down folder lid 3, open the sucker driving switch 21 of magnetic suction disc 2, magnetic suction disc 2 will hold rapidly adhesive platform 31, and upper locating slot 33 blocks the first half of the front straight tube 8 of base weldering simultaneously, and left side 81 and right side 82 will combine under the compression of folder lid 3; Re-use welding equipment and carry out welding to left side 81 and right side 82, both ends of the surface will be connected; After welding terminates, close sucker driving switch 21, magnetic suction disc 2 eliminates the attraction to adhesive platform 31, and folder covers upwards to be opened under the effect of back-moving spring 5, can take off soldered base.
In the present embodiment, the large 22mm of the degree of depth of locating slot 11 under the depth ratio of described protection mouth 15, its objective is that before preventing base from welding, straight tube 8 produces thermal deformation to clamp body 1 in welding process, thus affects the service life of pickup and clamp body 1; The end of guiding screw pole 4 is provided with stop nut 6, and this stop nut 6 can stop folder lid 3 to depart from guiding screw pole 4 under the effect of back-moving spring 5, affects it and normally uses; Sucker driving switch 21 is provided with several gears, varying in size of different gear adsorption magnetic forces, can use according to the material property of base and a certain gear of gauge choose reasonable.
In the present embodiment, the described U-shaped shape of pilot hole 32, this structure can guarantee the folding smoothly of folder lid 3; Limit, hole is 38mm to the monolateral distance at guiding screw pole 4 edge, and the amplitude that this distance can make folder lid 3 open is moderate, is conducive to picking and placeing workpiece; Described upper limit position groove 33 and the groove depth of lower limit groove 11 are respectively thick 2.2 times of base material; Groove width is 1.8mm larger than substructure height respectively, this had both ensured to locate reliably straight tube 8 before base weldering, was unlikely again straight tube 8 and stuck between upper limit position groove 33 and lower limit groove 11 before causing base to weld, affected and pick and place workpiece, thus ensure that welding quality, turn improve production efficiency.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; although with reference to above-described embodiment to invention has been detailed description; those of ordinary skill in the field still can modify to the specific embodiment of the present invention or equivalent replacement; these do not depart from any amendment of spirit and scope of the invention or equivalent replacement, are all applying within the claims awaited the reply.
