Description

A kind of punch die projective table type exempts from flange-type fuel tank

Technical field

This utility model relates to fuel tank, is specifically related to a kind of punch die projective table type and exempts from flange-type fuel tank.

Background technology

During the devices such as the most general fuel tank, installs such as fuel-quantity transducer on surface, fuel monitor, need first at fuel tank Surface perforate.Then according to installing device contour structures and tank surface bore size, the flange that processing is installed for device, complete Cheng Hou, by flange welding to tank surface perforate, just can carry out device installation.Such part is processed, and welding process causes Production time is wasted, and production efficiency is low, and, welding often leads to tank body of oil tank and deforms, and after a long time use, easily Produce fuel tank weld cracking, the problem of fuel tank leakage of oil.

This utility model eliminates to be needed when tank surface installing device to process circular hole, flange and flange welding, saves Production time, simplify production technology, reduce production cost, and ensure that production safety, improve production efficiency, tool There is higher Social benefit and economic benefit.

Summary of the invention

The purpose of this utility model there are provided a kind of punch die projective table type and exempts from flange-type fuel tank, and it has at tank surface During installing device, it is not necessary to the advantage of welded flange.

The utility model is achieved like this, a kind of punch die projective table type exempts from flange-type fuel tank, and it includes oil filler, top box Body, lower box, oil return opening, liquid level display, fuel-quantity transducer, oil-in；It is characterized in that: upper box and lower box seal even Connecing, described upper box uses Sheet Metal Forming Technology directly to form boss at tank surface, is separately installed with and adds on the boss of upper box Hydraulic fluid port, oil return opening, liquid level display, fuel-quantity transducer, be provided with oil-in on lower box.

Of the present utility model have the technical effect that this utility model by design punch die projective table type exempt from flange-type fuel tank, solve During tank surface installing device, production cost is high, and technique is more complicated, and production efficiency is low, and in the later stage uses easily Produce leakage of oil, cause waste of material and the low phenomenon of the quality of production,

A kind of punch die projective table type exempts from flange-type fuel tank method particularly includes: with circular die, process on fuel tank upper box Meeting the installation base of device size, owing to boss is that punching press produces, boss surface is smooth, and structural strength is high, and letter installed by device Easily, firmly, fuel tank overall leveling, attractive in appearance, no-welding-seam, not easy to leak.

This device course of processing is easy, cancels processing and the welding of flange, has saved production cost, improves production effect Rate, has higher Social benefit and economic benefit.

Detailed description of the invention

As Figure 1-5, a kind of punch die projective table type exempts from flange-type fuel tank, it include oil filler 1, upper box 3, lower box 2, Oil return opening 4, liquid level display 5, fuel-quantity transducer 6, oil-in 7；It is characterized in that: upper box 3 and lower box 2 are tightly connected, Described upper box 3 uses Sheet Metal Forming Technology directly to form boss 8 at tank surface, is separately installed with and adds on the boss of upper box 3 Hydraulic fluid port 1, oil return opening 4, liquid level display 5, fuel-quantity transducer 6, be provided with oil-in 7 on lower box 2.

As shown in Figure 1 and Figure 2,1, this fuel tank upper box use Sheet Metal Forming Technology directly tank surface formed boss, be used for At tank surface installing device；Such as example liquid level display and the installation of fuel-quantity transducer in figure, common fuel tank typically uses weldering After acting flange, liquid level display and fuel-quantity transducer are installed on flange.And this fuel tank uses Sheet Metal Forming Technology direct at upper box Form boss at tank surface, liquid level display and fuel-quantity transducer are installed on the boss on fuel tank upper box surface.Pass through Circular die is at fuel tank upper box surface punching press boss, and the boss being stamped and formed out can be used for the flange that alternative device is installed, and exempts from Except part and operations such as processing flange, tank surface perforate, flange weldings, fuel tank is made the most only to use a kind of thin-walled part Material is processed, it is not necessary to processes thick and heavy flange and welds it, and production cost can be greatly reduced, and improves production efficiency.

During the devices such as this utility model solves common tank surface and installing such as fuel-quantity transducer, fuel monitor, Need in tank surface perforate, and welded flange on hole, form satisfied certain flatness, the plane installed for device, The material used due to fuel tank is generally the thin-wall boards after 1.0mm, a large amount of perforate of tank surface, then throat thickness one As flange more than 8.0mm, easily cause fuel tank in welding, produce large deformation, cause tank surface to rise and fall, out-of-flatness, and Too much the existence of weld seam, is easily caused fuel tank leakage of oil.

This utility model eliminates general fuel tank to be needed when surface mount device to process circular hole welded flange, saves Production time, simplify production technology, reduce production cost, and ensure that production safety, improve production efficiency, have Higher Social benefit and economic benefit.
