Abstract

The utility model discloses a polyurethane buffer used at two ends of a pipe rolling factory rake manifold chain machine and a sawing machine and has a function of blocking and position limit. The buffer includes a collision-proof plate and a connecting part which are embedded in the elastic buffer body to form an integrated structure; the collision-proof plate and the connecting part are respectively arranged at two sides of the elastic buffer body; the connecting part can adopt a connecting bolt or a flange with a connecting bolt (connecting hole) with a connecting end exposed externally. By adopting the polyurethane foaming technology, the utility model makes the collision-proof plate and the connecting plate embedded in the elastic buffer body be wholly poured into forming. The utility model can sufficiently adsorb the impact, makes the impacting object (steel pipe) in the production line not sprung out of the track, solves the hidden trouble in production, relieves the vibration of the equipment, prolongs the service life of the equipment, reduces the noise pollution in production workshop, improves the production efficiency, implements the localization of the imported equipment fittings, reduces the production cost, and improves the economic benefit of the enterprise.

Description

A kind of polyurethane bumper absorber

One, technical field

The utility model belongs to the buffer unit technical field, is specifically related to a kind ofly be used for tube rolling factory comb chain making machine and machine for sawing two ends work the polyurethane bumper absorber that stops position-limiting action.

Two, background technology

At present, the buffer that tube rolling factory comb chain making machine and machine for sawing two ends use all with the import simultaneously of its equipment, roughly has following two kinds:

1, gas cushion.This kind buffer mainly reaches the buffering purpose according to the Compressed Gas in the cylinder.The piston rod of the steel pipe cushion at collision cylinder that moves on production line top, piston motion make and produce that nature is swollen to rise behind the gas pressurized, the piston pushed home, have so just realized the cushioning effect of gas cushion.But this kind buffer does not have aerating device, is fully to inflate naturally by natural gas, and this has just proposed very high requirement to the air-proof condition of gas cushion, must accomplish that piston and cylinder body are never wornout.Well imagine that this is impossible.Therefore, the service life of gas cushion is low, and costs an arm and a leg, and must so just must cause the reduction of production efficiency and the raising of production cost to foreign procurement.In addition, the noise that produces when steel pipe that moves on production line and the collision of the cylinder piston rod of gas cushion top is very big, up to 80---100 decibels,, must form serious noise pollution as tens places being arranged in the workshop all bumping against.

2, plank buffer.This buffer is that several solid woods are linked together, and makes the rectangle plank buffer of 600 * 350 * 200mm, is with 4 bolts this buffer to be fixed on the equipment of tube rolling production line.But, plank buffer anticollision ability, when the steel pipe of 3 operations clashed into the plank buffer simultaneously, impulsive force can reach more than 1000 kilograms.Particularly the steel pipe head is very irregular zigzag before sawing, and such rammer, impulsive force are clashed into the plank buffer, must have influence on the life-span of plank buffer, is no more than 1 month plank buffer usually and will be crashed and cause coming off.

Above-mentioned two kinds of buffers that carry with the rolling tube equipment production line of external introduction owing to absorb the ability of impact kinetic energy, have increased the holding capacity of production equipment, equipment often is under vibration and the unsure state moves, and have reduced the service life of equipment.Particularly when equipment moved under vibration and labile state, steel pipe existed the serious person and equipment breakdown hidden danger because speed of service instability ejects track sometimes.

Three, summary of the invention

The purpose of this utility model provides that a kind of cost is low, and the life-span is long, can reduce noise pollution, makes that production equipment operates steadily, safe and reliable polyurethane bumper absorber.

The utility model adopts following technical scheme to realize:

Scheme (one): this buffer comprises Crashworthy plate and connecting piece, be characterized in that connecting piece adopts coupling bolt, Crashworthy plate and coupling bolt be embedded in constitute overall structure in the elastic buffer body, Crashworthy plate and coupling bolt lay respectively at two sides of elastic buffer body, and the connecting end of coupling bolt exposes.

Scheme (two): this buffer comprises Crashworthy plate and connecting piece, is characterized in that connecting piece adopts flange, and Crashworthy plate and flange are fixed on elastic buffer body two sides formation overall structure, be fixed with coupling bolt on the flange or connecting pore is arranged, and connecting end exposes.

In technique scheme, come off for preventing that described Crashworthy plate and connecting piece from use causing, Crashworthy plate place and connecting piece place are provided with built-in fitting.

It is as a whole that the utility model is that elastic buffer body that the connecting piece that adopts the polyurethane foam technology will be positioned at the Crashworthy plate of buffer striking face and buffer base position is embedded in polyurethane material is built moulding.This buffer structure is simple, and is reasonable in design, safe and reliable, and it can fully absorb the impulsion energy, not only makes the alluvium (steel pipe) on the production line do not ejected track, solved the potential safety hazard in producing; And the vibration that has alleviated equipment, reduced the noise pollution of workshop the service life of having improved equipment, improved production efficiency; Also realized simultaneously the domestic part of import equipment production line, made enterprise reduce production cost significantly, thereby improved economic benefit of enterprises.

Five, the specific embodiment

Embodiment (one): this polyurethane bumper absorber among Fig. 3 is will be put in Crashworthy plate 1 in the mould and coupling bolt 3 with the polyurethane foam technology to water and build up overall structure, Crashworthy plate 1 and coupling bolt 3 are embedded in the elastic polyurethane buffer body 2, and Crashworthy plate 1 is positioned at the striking face place of buffer, and the coupling bolt 3 that exposes is positioned at the base position of buffer.The utility model can be made into the cuboid structure, and Crashworthy plate 1 is an iron plate, comes off for preventing it, and Crashworthy plate 1 back is provided with built-in fitting 4.In like manner, coupling bolt 3 places at this buffer base place also are provided with built-in fitting 4.

Embodiment (two): the polyurethane bumper absorber that provides among Fig. 4 is cylindric, and the flange 5 of band coupling bolt is selected in its connection for use.Coupling bolt 3 can weld fixing with fixing of flange 5, it is fixing also coupling bolt 3 can be penetrated flange 5, the Crashworthy plate 1 of band built-in fitting 4 and the flange 5 of band built-in fitting 4 are put into mould, the flange 5 of Crashworthy plate 1 and band coupling bolt is watered with elastic buffer body 2 by its foaming technique with polyurethane material and to build up an integral body, and Crashworthy plate 1 is positioned at the striking face place of buffer, and the flange 5 that exposes coupling bolt 3 is positioned at the base position of buffer.

As the connection form of the utility model employing flange 5, also can not establish coupling bolt on the flange 5 according to the structure of equipment junction, be provided with connecting pore, with connection satisfied and equipment.
