Description
Affiliated technical field
The utility model relates to a kind of mechanical stop hook formula secondary pulse and catches plastic pipe impact test machine, belongs to building materials experiment test device technical field.
Background technology
Plastics are to be basis with manual work or natural high molecular polymer, plastic molding in process and obtain goods.In general, plastic products have the characteristic of plasticity and creep, and conduit therefore made of plastic is done the time spent and can be produced distortion receiving external force, and shock resistance is to estimate the important indicator that tubing bears footpath outward force characteristic.At present; The principal feature that detects plastic pipe shock resistance testing machine commonly used is digital display, microprocessor program control, the anti-secondary pulse of electromagnetic braking; Though the test accuracy rate is higher, apparatus structure is complicated, price is more expensive, can't be applicable to the grass-roots unit that condition is limited.Both satisfied code requirement, economic, suitable, easy and simple to handle again, plastic pipe shock resistance test flexibly with the simple type drop hammer impact testing machine also seldom.
Summary of the invention
The purpose of this invention is to provide a kind of mechanical stop hook formula plastic pipe impact test machine; Utilize simple mechanical mechanism; Realization replaces the function of traditional electrical minor device to the seizure of the secondary pulse that drops hammer and the recovery of mechanism, reduces plastic pipe anti-impact test machine cost.
The technical scheme of the utility model is: mechanical stop hook formula secondary pulse is caught plastic pipe impact test machine; Comprise Vertical Rack 8, be loaded on vertical litter 2 on the Vertical Rack, be fixed in taper hook baffle plate 1 on the vertical litter, drop hammer promote and releasing mechanism 3, be placed in drop hammer promote and releasing mechanism on drop hammer 4, base jacking gear 7 and anti-secondary pulse mechanism; Anti-secondary pulse mechanism forms by being loaded on the anti-secondary pulse retaining device 5 of the cover of two on Vertical Rack 8 lower beam; The anti-secondary pulse retaining device 5 of two covers is positioned at the both sides of workpiece 6 tops and vertical litter 2, is a kind ofly to rely on spring force that it is set back also can to prevent to drop hammer the device of secondary pulse.
Said dropping hammer promotes and releasing mechanism 3 comprises the hook slide plate 3-1 that is placed on the vertical litter 2 and the hook 3-2 of its underpart, the hoisting rope of coupling hook slide plate 3-1; 4 upper ends of dropping hammer have annulus, drop hammer to promote and the hook 3-2 of releasing mechanism 3 bottoms is placed on 4 the annulus of dropping hammer.
The anti-secondary pulse retaining device 5 of every cover of said anti-secondary pulse mechanism comprises baffle plate 5-2, spring 5-1 and stop hook 5-3; Stop hook 5-3 upper end is hinged on Vertical Rack 8 lower beam; Baffle plate 5-2 upper end is hinged on the stop hook 5-3; Put up on the gib head of stop hook 5-3 lower end the lower end of baffle plate 5-2, and spring 5-1 is arranged between stop hook 5-3 and frame 8 lower beam.
The utility model can be according to the concrete size of sample 6; Regulate base jacking gear 7, drop hammer 4, through taper hook baffle plate 14 the automatic release that realizes dropping hammer along two vertical litter 2 (circular guideway) free-fallings; Need not any electronic installation, rely on and free-handly can accomplish experiment.Can select corresponding ram hammer capitiform formula according to specimen size, the weight of dropping hammer can be adjusted through the increase and decrease balancing weight.
The principle of work of the utility model is: at first regulate the height of base jacking gear 7 through up-down stretching screw rod, sample 6 is adjusted to predetermined shock height.Then through dropping hammer and releasing mechanism 3, will drop hammer and 4 mention, when mentioning taper hook baffle plate 1 place, the hook 3-2 of the lifting gear 3 that drops hammer is strutted by taper hook baffle plate 1, drops hammer 4 to break away from hook 3-2 and free-falling impact specimen 6 is accomplished sample shock resistance experiment.Conical baffled 1 is fixed on the vertical litter 2 of specified altitude position, and when falling when dropping hammer lifting gear 3, hook 3-2 can catch on the annulus at 4 tops of dropping hammer automatically under action of gravity, and 4 the action of mentioning then can repeat to drop hammer.4 free-fallings of dropping hammer strike when preventing secondary pulse retaining device 5, install stressed swing left, and after dropping hammer, baffle plate 5-2 sets back under the elastic force effect of spring and puts; Drop hammer and clash into test specimen 6 back bounce-backs 4 first time, strike stop hook 5-3 bottom, its backboard 5-2 is with 4 rises of dropping hammer; When dropping hammer 4 when falling for the second time, 5-3 blocks by stop hook, thereby has stoped 4 the secondary pulse of dropping hammer.When testing, through dropping hammer and releasing mechanism 3 is mentioned and dropped hammer 4, anti-secondary pulse retaining device restores automatically next time, and need not to carry out other operation can test next time.
Compare with the existing testing machine that uses, the utility model can accurately be accomplished the test of tubing shock resistance, and is simple in structure; (need not any electrical equipment, just free-hand can accomplish experiment) easy and simple to handle, low price; Volume is little in light weight; And low to Test Condition Requirements, be fit to basic unit and use, have higher application and popularization value.
