Description
Technical field
The utility model patent relates to a kind of pipe clamp producing device, particularly the cold stewing producing device of a kind of wafer type band steel pipe clamp.
Background technology
Pipe clamp is that piping load is delivered to the element on pipe frame structure, to reducing pipe stress, guarantees that the even running of pipeline long period plays vital effect.Two two ends that wafer type band steel pipe clamp is simmered into by band steel form with the semicircular arc structure of straight flange with through the bolt of straight flange upper bolt hole.
Because material therefor is common and simple in structure, for reducing costs, wafer type band steel pipe clamp mostly is field fabrication but not entrusts machinery plant's processing.Traditional wafer type Flat steel pipe card manufacturing method and step are as follows:
1, select to meet the band steel material of drawing requirement, cutting stock after the clean material that accounting making pipe clamp is required rule of thumb amplification reserve.
2, make as required the specification of pipe clamp, one section of steel pipe matching with pipe clamp specification is vertically welded on steel platform as the mould of simmering tubulation card.
3, one end of band steel is weldingly fixed on steel platform to the length of pipe clamp straight flange the length of assurance band steel from pad to mould steel pipe point of contact is greater than and completes.
4, from the position, point of contact (being the starting the arc position of semi arch) of band steel and mould steel pipe, utilize oxygen acetylene flame to heat band steel, when heating-up temperature reaches 700 degree when above, with iron hammer, knock band steel, make its along mould steel pipe gradually fire bending become half-circle-arc shape.
5, utilize oxygen acetylene flame cut the pad of band steel on steel platform open and polish flat.
6, utilize oxygen acetylene flame to heat the flanging position of band steel straight flange (being the starting the arc position of semi arch), when heating-up temperature reaches more than 700 ℃, be placed on chopping block and knock with iron hammer, complete flanging.
7, utilize the surplus of two straight flanges of oxygen acetylene flame cutting.
8, auger shell keyhole on straight flange.
9, the semicircular arc structure with straight flange by two two ends, utilizes the bolt through straight flange upper bolt hole to link together.Complete the making of wafer type band steel pipe clamp.
Above-mentioned oxygen acetylene flame is heated to uniform temperature by band steel, the method for utilizing fire bending that iron hammer knocks on mould steel pipe and chopping block to make pipe clamp, and the wafer type band steel pipe clamp of making can meet instructions for use, but has following shortcoming:
1, because the larger scale error of wafer type band steel pipe clamp existence is made in fire bending, clean material can not be descended before with the semicircular arc structure fabrication of straight flange in each two ends, but will adjust, make the required clean material of pipe clamp and rule of thumb after amplification reserve, descend woollen, after fire bending completes, excising again clout.
2, because fire bending making wafer type Flat steel pipe calorie requirement is by a plurality of operations such as clout that band steel is welded on steel platform, oxygen acetylene flame heats, iron hammer knocks band steel fire bending, cutting pad is also polished, cut two straight flanges, and craftsmanship is had relatively high expectations, so efficiency of construction is lower.
3, owing to being that iron hammer knocks and forms after oxygen acetylene flame heating, the wafer type band steel pipe clamp appearance forming that fire bending is made is poor.
4, because fire bending making wafer type Flat steel pipe calorie requirement is heated to band steel more than 700 ℃, in manufacturing process, be manual operation, so exist, scald risk.
In sum, traditional oxygen acetylene flame is heated to uniform temperature by band steel, the method of utilizing fire bending that iron hammer knocks on mould steel pipe and chopping block to make pipe clamp, the wafer type band steel pipe clamp of making can meet instructions for use, but material is wasted in existence, efficiency of construction is low, pipe clamp appearance forming is poor, have the shortcomings such as the risk of scald.
