Abstract
The utility model relates to an extruding mould test block machine which is composed of a vibrating table, a bracket and a test mould train. The utility model is characterized in that a material bin capable of moving up and down is arranged in the center of the bracket arranged above the test mound, a pressurizing hammer head is arranged above the material bin, and the upper part of the bracket is fixedly connected with an auxiliary thrust device. The material bin and the test mould are positioned by a rabbet. The pressurizing hammer head is provided with a limiting groove to limit the depth thereof. The auxiliary thrust device is composed of a screw rod thimble, a screw rod sleeve barrel and a hand wheel. The utility model has the advantages that the test block molding process approaches the technology that a hollow plate is formed by an extruding machine, the extruding mould test block machine has a vibration and extrusion combining process, and the deflection of the evaluating result of the strength of test blocks is small. The utility model is suitable for manufacturing test blocks of extrusion molding components.
Description
The utility model belongs to the concrete crushing strength testing equipment, particularly a kind of testing equipment that is used to make the extrusion modling concrete test block.
At present, make the equipment of concrete test block, normally die trial and shaking table, with the concrete material die trial of packing at twice, with drill rod insert smash after, be placed on vibratory compaction moulding on the shaking table.This testing equipment of being made up of die trial and shaking table only is applicable to and estimates the die process that adopts the vibratory compaction moulding, the concrete core slab of punching block explained hereafter, the test block label of member.
The extruder that developed recently is used is produced slab member, is a kind of new mask-making technology method, and it is simple that it has technology, and labour intensity is low, the production efficiency height, and the place turnover is fast, saves material and advantage such as the energy, obtains at home promoting.This technology is with extruding and vibrates two kinds of methods and act on concrete simultaneously, makes it closely knit moulding.The solidity ratio of the slab member of producing with this kind method adopts the packing of the slab member of vibration moulding to want high separately, so the actual compressive strength of the compressive strength of the concrete test block that the employing usual method is made and the cored slab of extruder production has than big-difference, far can not be used for estimating the intensity that cored slab is produced in extruding.
The purpose of this utility model is, in common shaking table and die trial, set up feed bin and pressue device, adopt the method for the concrete density identical reinforced with extruder making sheet, make concrete test block through the method that extruding, vibration combine, make the test block forming process more meet the technological process that extruder is produced cored slab, make the packing of test block reach the packing that extruder is produced cored slab.
Extrusion modling test block machine of the present utility model is made up of shaking table, support, die trial, it is characterized in that, the support central authorities above die trial are provided with feed bin, and the feed bin top is provided with pressure hammer head, and the support upper fixed is connected with auxiliary augmentor.
The end opening of feed bin aligns with the suitable for reading of die trial, and with cuff seam location, the cross sectional shape of feed bin is identical with the cross sectional shape of die trial.
The vertical section of pressure hammer head is the T type, and top tup section is greater than bottom hammer body section, and xsect is identical with the die trial xsect, inserts the hammer height degree of feed bin, has stopper slot to limit and equates that with the feed bin height pressure hammer head is movable to the die trial position of upper.
Auxiliary augmentor is to be fixed on screw rod thimble and the handwheel that top board central authorities are provided with on the support, and the end face of pressure hammer head is pasted on screw rod thimble top, and the screw rod thimble is connected with the screw sleeve of rack plate.
Using method of the present utility model is, will with the concrete material of the identical unit weight of extruder moulding cored slab, at twice through feed bin, quantitatively add in the die trial, with drill rod insert smash after, put into pressure hammer head; Through shaking table vibration, the pressure hammer head extruding when pressure hammer head sinks to predetermined spacingly, is promptly finished test block manufacturing process; Sink less than predetermined spacing as pressure hammer head, can rotate handwheel, make screw rod thimble top paste the pressure hammer head end face and apply extruding force, rely on the dynamometry clock gauge on the screw rod thimble to judge whether the size of extruding force reaches the extruding force value that extruder is produced cored slab.
The utility model has the advantages that the test block forming process more levels off to extruder moulding cored slab technology, vibration and extruding anabolic process are arranged; The test block concrete material is according to reinforced with the method for the identical unit weight of extruder making sheet, and the concrete capacity is fixed; Pressure hammer head sinks to having spacing, can limit time of vibration and pressure process, and therefore, the deviation of intensity of test block evaluation result is less.Be applicable to the making of extrusion modling test block.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the structural representation of extrusion modling test block machine.
As seen from the figure, extrusion modling test block machine is made up of shaking table 1, support 2, die trial 3, it is characterized in that, support 2 central authorities above die trial 3 are provided with feed bin 4, and the feed bin top is provided with pressure hammer head 5, and the support upper fixed is connected with auxiliary augmentor 6.
The end opening of feed bin aligns with the suitable for reading of die trial, and with cuff seam location, the cross sectional shape of feed bin is identical with the cross sectional shape of die trial.
The vertical section of pressure hammer head 5 is the T type, and top tup section is greater than bottom hammer body section, and xsect is identical with the die trial xsect, inserts the hammer height degree of feed bin, has stopper slot 10 to limit and equates that with the feed bin height pressure hammer head is movable to the die trial position of upper.
