Abstract

The utility model relates to a multifunctional ingot stripper which is used for the highway material test and the ingot stripping of a test piece in highway construction. The methods of hydraulic pushing, reinforcing a rod, etc. are used in the ingot stripper, so that the test piece is convenient to strip, and the yield of the test piece is raised. The utility model overcomes the defects that when a screw rod which is used currently is extruded by rotation, the test piece is not easy to extrude, but is easy to damage and the qualified rate is low, and is suitable for preparing the test piece with the big diameter of phi 100 mm, phi 150 mm, etc.

Description

Multi-function hydraulic ingot stripper

The utility model relates to the road material test tool in the highway engineering field.

In the construction of the highway process,, need the test specimen of preparation different size to be used for various tests for identifying unit weight, water cut and the mechanical property of soil, heat shop oil pitch prill concrete road material, sub-surface compound.For pitch prill road material or concrete sample are deviate from easily, need add very big power to test specimen from the mould tube.At present the strippers that use in a large number of highway engineering department rotate test specimen in the downward roof pressure mould tube as the disc type leading screw, allow test specimen deviate from from the mould tube, fall within on the pallet of being with spring.This stripper has following two shortcomings, one, because leading screw top power is limited, and the above big specification test specimen of some test specimen demoulding difficulty, particularly φ 100mm is difficult to eject.Two, carriage insufficient height, spring force is softer, drops on after test specimen is deviate from from the mould tube often to occur the crack on the pallet, even disconnects, and can not guarantee the qualification rate of test specimen.

The purpose of this utility model designs a kind of simple in structure exactly, and the demoulding is rapid, and is easy to operate, and the demoulding utensil of ensuring the quality of products is to satisfy the demoulding of different size test specimen.

Technical characterictic of the present utility model is: adopt hydraulic jack as demoulding power, and be equipped with the top board that adapts to different size, the moving of mould tube when preventing the big specification demoulding taked to add the method for fixed bar around the mould tube.

The utility model has the advantages that: one, use compacting process, the φ 50mm that static pressure method is done, φ 100mm, φ 150mm all size test specimen all can be deviate from from the mould tube smoothly, two, make progress because of test specimen, pallet and spring supporting mechanism have been saved, three, the hydraulic pressure top is slowly pushed to, and has improved the qualification rate of test specimen.

Operation principle of the present utility model such as Fig. 1, base plate 1, la m 2, top board 3 is connected with four threaded supports 4 by nut, 10 tons of jack 5 place the base plate center upper portion, la m 2 all can be according to its height of needs flexible modulation of different size test specimen with top board 3, mould tube 6 places in the middle of the la m top, loading onto top board according to different size compresses mould tube and top board, be to make the unlikely movement of mould tube insert fixed bar 8 by the hole, garden 7 on the top board when producing big specification test specimen, as long as when the demoulding, press jack 5, the mandril of lifting jack lower compression leg in the roof pressure mould tube that rises gradually, the test specimen in the mould tube is just slowly deviate from from the hole, garden of top board.

Most preferred embodiment of the present utility model is as follows:

Four supports 4 are respectively the threaded iron of φ 30mm, base plate 1 long for 340mm, wide be 290mm, thick be 20mm iron plate, four angular bits at 35mm place, distance edge have the hole, garden of φ 32mm, to make things convenient for packing into of support 4.La m 2 is long 340mm, wide 290mm, thick 6mm iron plate, the center has the hole, garden of φ 60mm, the φ 118mm concentric with the hole, garden, φ 172mm garden Zhou Shangsi or six five equilibriums are drilled with the hole, garden of φ 8mm, these holes, garden are used to produce φ 100mm, from the top board corresponding aperture, insert fixed bar during φ 150mm test specimen, be drilled with hole, φ 32mm garden with the support of conveniently packing at 35mm place, distance edge, top board 3 has 3 kinds of different sizes, be long 340mm, wide is 290mm, thick is 20mm, 35mm place, four angular distance edges is drilled with the hole, garden of four φ 32mm, with the support of conveniently packing into, wherein produce the middle hole, garden that has φ 54mm of top plate of φ 50mm test specimen, deviate to make things convenient for test specimen, produce the middle hole, garden that has φ 104mm of top plate of φ 100mm test specimen, deviate to make things convenient for test specimen, for preventing that further the mould tube from moving, the fourth class or six five equilibriums are drilled with hole, φ 8mm garden respectively on week in the garden of φ 118mm, in order to insert fixed bar 8, the top plate central authorities that produce φ 150mm test specimen have the hole, garden of φ 154mm, deviate to make things convenient for test specimen, for preventing that further the mould tube from moving, the quartern or six five equilibriums are drilled with hole, φ 8mm garden in order to insert fixed bar 8 on week in φ 172 gardens.

The utility model is suitable for road engineer Instrument factory to be produced, and is the desirable replacement product of former stripper, and good economic and social benefit is arranged.
