Abstract
The utility model provides a thin expanded rubber compression set testing device in order to solve the problems that the thin expanded rubber compression set testing device is nonuniform in sample compression stress and inaccurate in compression amount determination in the prior art. The device comprises a bottom plate, equal-height sleeves, fixing bolts, an upper plate, a pressing column, a pressing bolt, an upper pressing plate, a lower pressing plate, upper brackets, lower brackets and dial indicators, wherein the four fixing bolts penetrate through through holes at the four corners of the bottom plate, then penetrate through corresponding through holes of the upper plate, and are fastened by nuts; a pressing hole is formed in the center of the upper plate; the pressing column is arranged in the pressing hole; the upper brackets are arranged on the two sides of the upper pressing plate; the dial indicators are fixed on the upper brackets; the lower brackets are arranged on the two sides, corresponding to the upper brackets, of the lower pressing plate; and the upper surfaces of the lower brackets are contacted with detection heads of the dial indicators. The device has the technical benefits that the device can uniformly compress and load an expanded rubber sample, and can accurately determine the compression amount.
Description
Technical field
The utility model relates to a kind of thin stephanoporate elastomeric material compression set measuring technology, specially refers to a kind of thin stephanoporate elastomeric material compression set proving installation.
Background technology
The thin stephanoporate elastomeric material belongs to macromolecular material, has the viscous-elastic behaviours such as lax, creep, closely related with time and the temperature of External Force Acting.In certain external force and hot environment, polymer segment will be reset and solidify, and produces permanent distortion, and therefore, compression set is an important mechanical property of macromolecular material.For the long-time material used under high ambient conditions, compression set is also an important indicator.Usually, the method of testing of thin stephanoporate elastomeric material compression set is first the thin stephanoporate rubbery sample to be compressed to certain height, and keep this decrement, at high temperature carry out the stationary temperature processing, then, in room temperature unloading and recovery, recover to compare the variation in thickness of rubbery sample before and after test after a period of time, measure thus the compression set of expanded rubber material.Prior art thin stephanoporate elastomeric material compression set test adopts the bolt pressue device to be tested, adopt four bolts by two overlapping linking together of rigidity steel plate, placing porous elastomeric material sample between two block plates, tight a bolt and realize pressurization, adopt vernier caliper test compression amount, then, steel plate being communicated with to sample is placed in sweat box and carries out the constant temperature processing.Owing to adopting four bolts to exert pressure from four angles of steel plate, therefore, stressed very inhomogeneous.And adopt the vernier caliper manual measurement can not guarantee the Accurate Determining of decrement.Obviously, prior art thin stephanoporate elastomeric material compression set proving installation exists sample compression discontinuity, and decrement is measured the problems such as inaccurate.
Summary of the invention
The sample compression discontinuity existed for solving prior art thin stephanoporate elastomeric material compression set proving installation, decrement is measured the problems such as inaccurate, the utility model proposes a kind of thin stephanoporate elastomeric material compression set proving installation.The utility model thin stephanoporate elastomeric material compression set proving installation comprises base plate, contour cover, set bolt, upper plate, pressured column, pressurization bolt, top board, lower platen, upper bracket, lower carriage and clock gauge; Four set bolts are set with contour cover after passing the through hole of four corners of base plate, and then also use fastening nuts through the corresponding through hole of upper plate, form framed structure; Be provided with the pressurization hole at the center of upper plate and be provided with internal thread on pressurization top, hole; The diameter of pressured column is complementary with pressurization hole internal diameter and is arranged in the pressurization hole; Pressurization bolt is arranged on pressurization internal thread place, hole and contacts with the pressured column upper surface by bulb; Be provided with top board below pressured column, in the both sides of top board, be provided with upper bracket, be fixed with clock gauge on upper bracket; Be provided with lower platen at the base plate center, in the lower platen both sides, corresponding upper bracket place is provided with lower carriage, and the upper surface of lower carriage contacts with the detection head of clock gauge.
The useful technique effect of the utility model thin stephanoporate elastomeric material compression set proving installation is to carry out even compression-loaded to the expanded rubber sample, and can the Accurate Determining decrement.
The accompanying drawing explanation
Accompanying drawing 2 is structural representations of the utility model thin stephanoporate elastomeric material compression set proving installation measure portion.
Below in conjunction with the drawings and specific embodiments, the utility model thin stephanoporate elastomeric material compression set proving installation is further described.
Embodiment
Obviously, the useful technique effect of the utility model thin stephanoporate elastomeric material compression set proving installation is to carry out even compression-loaded to the expanded rubber sample, and can the Accurate Determining decrement.
