Description

Steel impact specimen horizontally-arranged row processing hydraulic anchor clamps

Technical field

The utility model relates to a kind of steel impact specimen horizontally-arranged row processing hydraulic anchor clamps.

Background technology

In order to identify the physical parameter of metal material, be that the producer or user often will carry out performance test to some associated materials.Because it is very big to detect the required sample quantities of examination, the unit of asking for the material model is more, and the time requirement of sampling is all anxious especially again, and this can process qualified test sample in enormous quantities apace with regard to needing enterprise.But owing to be subjected to the restriction of Processes and apparatus condition every aspect, it is also quite big to want to satisfy this demand difficulty by prior art, and at present, this difficult problem has become a bottleneck of current steel inspection technology.

Impulse test is one of essential items for inspection of metal material physical property test, the manufacturing process of the impact specimen of domestic iron and steel enterprises is divided into two classes substantially at present, common apparatus such as the first kind is the use bull-nose plane that generally adopts of current most enterprise, mill, mill, broaching machine are by procedure, the arrangement processing of part one by one.Not only efficiency is low, and labour intensity is big, and the crudy of sample is also undesirable.Second class is the enterprise after some newly-built or technological transformation, selected is horizontal Machining centers, though this equipment is more advanced, but also exist obvious deficiency, at first be that investment is excessive, purchasing a homemade horizontal Machining centers needs more than 300 ten thousand yuan, and cost of equipment of import then can be up to seven, 8,000,000 yuan.It is more that the another one problem is exactly this equipment number of changing knife in operation, can cause the obvious reduction of working (machining) efficiency thus.Except two above-mentioned class cooked modes, still find no the relevant design of other type so far both at home and abroad.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of steel impact specimen horizontally-arranged row processing hydraulic anchor clamps, this equipment not only can be realized the high-quality of sample processing, the powerful advantages of high-speed and small investment, and can also further improve the utilization factor of processing slab material.

Hydraulically operated fixture of the present utility model is provided with 90 ° of rotary systems of level and vertical 180 ° of switching mechanisms.Lathe is pressed X, Y, Z operation during cutting, and hydraulically operated fixture is provided with 90 ° of B axle rotations of level and vertical 180 ° of A axles upset operation locating device, is respectively equipped with rotation collision block and limited block on fixed underpan and rotating circular disk, constitutes five-axle linkage location tool setting cutting system.

Described 90 ° of rotary systems are: rotating circular disk is installed on the fixed underpan by live spindle, on the live spindle between two dishes, dividing gear is housed, dividing gear and the tooth bar engagement that is contained in fixed underpan one side, the outer end of tooth bar connects with the stretching oil cylinder with rotation.

Described vertical 180 ° of switching mechanisms are: overturning clamp is contained on the claw at rotating circular disk center by upset axle hinge, corresponding initial manufacture position is clipped in the workpiece on the overturning clamp, the overturning clamp rear side is contained in two corner compressed oil cylinders side by side, the top is provided with the vertical folder locking oil cylinder, horizontal clamping cylinder is equipped with on the right side, two side clamping cylinders that are oppositely arranged are housed in the left side of overturning clamp, the forward and backward both sides of workpiece when its installation site is an II section machining position after 180 ° of the corresponding overturning clamp upsets, the outer end upset servomotor of upset axle connects.

The advantage that the utility model had at first is that speed is fast, sampling convention according to the world, once the peace folder can be realized one group of transversely arranged three sample, whole processing of six interfaces and one group of " V " v notch v, production efficiency can reach 60-69 Parts Per Hours, is 3 times of horizontal Machining centers 18-21 Parts Per Hours.Second advantage is the quality height, and the sample accurate to dimension is ± 0.03mm, and the adjacent side non-perpendicularity is less than ± 0.02, and surfaceness is lower than Ra1.6 μ m, and every precision index all is higher than international standard.The 3rd advantage is exactly that equipment manufacturing cost is low, and the price of set of equipments only is 1/3rd of a homemade horizontal Machining centers.The 4th advantage is to save material, and the sampling of horizontally-arranged row only needs long one of on sheet material intercepting 75mm, and is then long at plate angle intercepting 160-220mm during the extended spread sampling, the edge strip that 400mm is wide, thereby can reduce consumptive material 1/3-1/2 relatively.The 5th advantage is to be exactly the technology advanced person, lathe is pressed X, Y, Z operation during cutting, hydraulically operated fixture can be realized 90 ° of B axle rotations of level and vertical 180 ° of upset A axle operation location, thereby has realized the location tool setting cutting of five-axle linkage, and numerically-controlled machine is become special-purpose machining center.
