Technical field
The invention belongs to fuel sensor technical field, especially a kind of oil pipe installation method of retort stand fuel sensor and the mould of closing-in structure and use thereof.
Background technology
At present, after the pipe end moulding of the oil pipe of retort stand fuel sensor, tube end diameter and pipe diameter differ larger, and oil pipe needs to be again arranged on the metallic plate punching hole of flange, and needs fit sealing.Conventional sealing and fastening means are for adopting soldering or argon arc welding, oil pipe two ends diameter is respectively Ф 9.5+0.1/-0.2mm, Ф 10.98 ± 0.15mm, when now the diameter of metallic plate punching hole must be greater than Ф 9.5, pipe end minimal head just can pack in punching hole, conventional value Ф 9.7 ± 0.1mm.The mode that this processing technology causes gap between pipe and punching hole to fill scolder by argon arc welding seals fastening welding, this product appearance being welded into is very poor, not only waste material and man-hour, and the positional precision of pipe is difficult to guarantee, product quality declines.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the object of this invention is to provide a kind of oil pipe installation method of retort stand fuel sensor, can simplify the difficulty of production, cost-saving, reduce fraction defective, obtain more high quality product, meet user demand.Another object of the present invention is to provide a kind of oil pipe of above-mentioned installation method closing-in structure is installed.The present invention also has an object to be to provide the mould that a kind of said method is used.
Technical scheme: in order to realize foregoing invention object, the technical solution used in the present invention is as follows:
An oil pipe installation method for fuel sensor first stamps out metallic plate punching hole on flange; Then the oil pipe of forming is put into metallic plate punching hole; Utilize closing in grinding tool to close up to metallic plate punching hole, make oil pipe closing-in structure, make the diameter of oil pipe closing-in structure be less than the end diameter of oil pipe; Finally weld fit sealing.
The oil pipe closing-in structure of the oil pipe installation method of described retort stand fuel sensor, is less than the annular projection of small end for being located at the diameter of metallic plate punching hole periphery.
Described protruding outer wall is tapered from top to bottom.
Described projection and flange are integral formula structure.
The closing in grinding tool of the oil pipe installation method of described retort stand fuel sensor, comprises upper mould piece, reinforcement, lower module and collapsible tube; Described collapsible tube one end is through reinforcement, and the other end and upper mould piece fix; On lower module, be provided with for placing the space of flange, at described reinforcement, be provided with the projection suitable with flange shape; Described collapsible tube port is horn-like, and internal diameter ecto-entad dwindles gradually, and outermost end size and the protruding external diameter of internal diameter are suitable.
Described upper mould piece is connected with upper holder.
Described lower module is connected with lower fixed frame.
The present invention, by adopting special closing-in mould, carries out punching press closing in to metallic plate punching hole, to reduce the gap between oil pipe tube wall and metallic plate punching hole hole wall on forcing press.Closing-in mould adopts upper and lower mould structure, meets normal stamping procedure requirement, adopts press, and efficiency is higher.Because mould is complete circle, the shape uniformity after closing in, full, outward appearance is good.Because mould closing in inner chamber has tapering, can, by regulating the descending depth of reinforcement, adjust the size of closing in, to obtain rational gap.
Beneficial effect: compared with prior art, the oil pipe installation method of retort stand fuel sensor of the present invention and the mould of closing-in structure and use thereof, this closing-in structure is simple, design ingenious, this installation method is simplified the difficulty of production, convenient operation, cost-saving, reduce fraction defective, obtain more high quality product, assembling by closing-in mould to oil pipe and metallic plate stamping parts, obtain on the one hand good outward appearance, accurate position dimension on the other hand, product meets client's requirement, effectively improved production efficiency, to be manually transformed into machinery production, directly close up, reduced the use of material, saved production cost, there is good practicality, can produce good economic benefit and social effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of oil pipe closing-in structure;
Fig. 2 is the structural representation of closing-in mould.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, retort stand fuel sensor primary structure comprises flange 1 and oil pipe 2, on flange 1, stamp out the metallic plate punching hole 6 of installing for oil pipe 2, oil pipe 2 tube end diameter and the pipe diameter of moulding differ larger, oil pipe 2 two ends diameters are respectively: small end 3 is Ф 9.5+0.1/-0.2mm, hold greatly 4 for Ф 10.98 ± 0.15mm, when now the diameter of metallic plate punching hole 6 must be greater than Ф 9.5, small end 3 just can pack in punching hole like this, conventional value Ф 9.7 ± 0.1mm.
The oil pipe installation method of retort stand fuel sensor of the present invention is first on flange 1, to stamp out metallic plate punching hole 6; Then the oil pipe of forming 2 is put into metallic plate punching hole 6; Utilize closing in grinding tool to close up to metallic plate punching hole 6, make oil pipe closing-in structure, make the diameter of oil pipe closing-in structure be less than small end 3 diameters of oil pipe 2; Finally adopt soldering or argon arc welding to weld fit sealing.
