Casting is Metal Melting to be smelt meet necessarily required liquid and water in casting mold, obtains the technical process of the foundry goods of reservation shape, size and performance through cooled and solidified, after leveling processing.Because the weight of dumbbell head, disc is generally all bigger, so need to adopt a large amount of pig iron.In addition, this process need adopts high temperature, thus need expend many energy, thus cause product cost to increase.Simultaneously, casting process is quite serious to the pollution of environment.According to statistics, 1 ton of qualified foundry goods of every production approximately will discharge dust 50kg, waste gas 1000-2000m
3, antiquated sand 1-1.3 ton, waste residue 300kg, about 2 tons of carbon dioxide.This shows, make body-building apparatus with casting and not only deviate from mutually that more---to improve people's fitness---incompatible with the purpose of nationwide fitness programs with the trend that the current whole society advocates energy-conserving and environment-protective.At present, I take charge of about 100,000 tons of annual production weight lifting dumbbell, disc etc., as replacing traditional casting technique with the present invention, annual discharging dust 5,000,000 kg, waste gas 10000-20000 ten thousand m of reducing
3, ten thousand tons of antiquated sand 10-13, about 200,000 tons of carbon dioxide.And foundry goods usually defectives such as pore, pin hole, slag inclusion, crackle, pit can occur owing to be subjected to multiple factor affecting, and product surface quality is not high.
In order to overcome the defective of casting, also have the people to adopt materials such as cement, concrete to make this type of equipment at present, but since the density of these raw materials mostly less than 3g/cm
3, less than half of iron density, therefore cause the volume of product to increase to be twice many, make troubles for transportation and use, therefore can't replace conventional cast technology.
In order to substitute casting, Chinese patent application numbers 200810120983.7 provides a kind of punching press perfusion type dumbbell by adopting the steel plate punch forming to make, handle between its two dumbbells stone roller adopts steel pipe or rod iron to connect, have the slurry perfusion hole on the dumbbell stone roller in the two dumbbells stone roller, mixed slurry is poured in two dumbbells stone roller and the handle.Its used mixed slurry is iron sand and glue mixture or iron sand and industrial brine mixed slurry, or ore in sand form and concrete mixed slurry, or iron sand and concrete mixed slurry, or iron sand, sand, concrete mixed slurry.This method complex technical process, the manufactured goods proportion of obtaining is at 3.0g/cm
3Below, also can't replace conventional cast technology.And generally there is the problem of distribution of weight inequality with the dumbbell made of mode of perfusion slurry, can brings discomfort to the user, even cause injured.The distribution of weight inequality also can cause the local surfaces of dumbbell to be easy to damage when stressed in addition.
Chinese patent application numbers 200710133286.0 provides the processing method of a kind of dumbbell and disc, this product is made of body and the rubber that is coated on body surface, body is made through moulding, drying by polyester concrete, wherein polyester concrete is made up of aggregate, no wax pattern unsaturated-resin, releasing agent, curing agent etc., and aggregate can be building stones, ore charge, the slag of small particle diameter or smelt slag.This method need adopt 150-160 ℃ hot extrusion briquetting technique to obtain profiled member, moulds time vaporization and produces bubble at product surface soaking to avoid moisture, therefore still needs to expend a large amount of energy.And because concrete proportion is 2.0g/cm
3, also have above-described problem.

The specific embodiment
In the following description, a large amount of concrete details have been provided so that more thorough understanding of the invention is provided.Yet, it will be apparent to one skilled in the art that the present invention can need not one or more these details and implemented.In other example,, be not described for technical characterictics more well known in the art for fear of obscuring with the present invention.
Manufacture method of the present invention mainly comprises technical process such as batch mixing, compacting, curing.
At first carry out batch mixing, generally for example the shot-like particle of iron content such as Iron Ore Powder, iron sand mixes with adhesive by a certain percentage of the weight and to drop into stirrer for mixing even.This batch mixing step can adopt mixer to carry out with the mode that manually combines.The granularity of wherein used shot-like particle is generally 3 order to 300 orders, is preferably 5 order to 250 orders, is preferably 10 order to 220 orders especially, is preferably 50 order to 200 orders again.The order number is hole count, is exactly the number of perforations that goes up per square inch, and the order number is big more, and the aperture is more little.In general, order number * aperture (micron number)=15000.Usually, granularity is thin more, even more, and it is easy more to mix.Yet granularity is little and the common price of uniform raw material is higher, and is difficult for obtaining.Therefore, this particle size range can be selected according to actual conditions.Also can process, for example grind, fragmentation, screening etc., so that its granularity before mixing is within the above scope obtainable, the undesirable raw material of granularity of institute.Therefore, manufacture method of the present invention also can comprise pulverising step in case of necessity.
The shot-like particle of described iron content can be that Iron Ore Powder, iron sand, iron and steel such as cut at the shot-like particle that contains ferro element or iron compound, but be not limited to these, in fact, as long as its iron-holder is more than or equal to 30 weight %, and get final product less than 100 weight %, therefore both can adopt Iron Ore Powder, iron sand or iron and steel to cut separately, also can use by any two kinds of mixtures that constitute in these materials, or adopt the mixture one of contain wherein at least, or adopt iron-holder other arbitrary substances within this scope.Less than 30 weight %, then will cause the proportion of product too small as iron-holder, need to take bigger volume thus, will make troubles to transportation and use.For improving the proportion of product, this iron-holder is preferably greater than 40 weight %, more preferably greater than 50 weight %.On the other hand, too high iron-holder must cause the straight line of cost to rise, and this manufacture method will lose cost advantage, so this iron-holder is more preferably less than 80% weight preferably less than 90 weight %.In a word, the producer can recently select to have the shot-like particle of suitable iron-holder according to cost-benefit.
Described adhesive is generally the metal adhesive, promptly is applicable to the bonding adhesive between metal and the metal.This type of adhesive can be the adhesive that comprises epoxy resin and/or phenolic resins, epobond epoxyn preferably, because the shot-like particle of the iron content that itself and the present invention adopt is comparatively compatible, products obtained therefrom packing height, therefore can obtain the product of high strength, high tenacity, not use other suitable bonding but also do not get rid of.In addition, both can use the commercially available prod, also can perhaps select or prepare the mixed adhesive that comprises above these adhesives for use according to actual conditions according to the synthetic corresponding adhesive of known method.Selection or compound method are well known to a person skilled in the art, do not repeat them here.Those skilled in the art will know that how to select corresponding curing agent (technological parameter of commercially available prod is all provided by manufacturer) according to selected adhesive and appointed condition.Adhesive and the curing agent part by weight in all preparation raw material (iron content shot-like particle, adhesive and curing agent) is generally 1 weight %-15 weight %, and preferably 3 weight %-12 weight % are more preferably 5 weight %-10 weight %.These auxiliary material ratios are too high, although can improve the product strength performance indications, may cause product proportion to descend, and it is unfavorable to bring for thus transportation or use, and cost also can rise.These auxiliary material ratios are low excessively, then cause bonding deficiency easily, and product strength descends.Therefore, can suitably determine both ratios in that the end properties index is satisfied under the normal condition of using.In addition, preferably normal temperature cure agent of the curing agent of Xuan Zeing herein perhaps needs the adhesive (being heat-curing type adhesive) of heating cure, and in a word, curing rate can not be too fast, is used for stirring, feed intake and suppressing so that possess sufficiently long effective storage life.Certainly,, also can adopt quick-setting adhesive, and will directly suppress after the vibration mixing in the described later mould cavity of raw mix if can guarantee to mix immediately (particularly particularly suitable) for the small dimension product.In addition, in order to protect environment better or to adapt to specific environmental protection standard, also can use non-solvent adhesive herein, with the harm of avoiding solvent evaporates to bring to environment.
Then, implement the compression moulding step.This pressing step can be implemented in any press.Preferred pressing pressure is 100kg/cm
2More than, preferred pressing pressure is 200kg/cm
2More than.Pressing pressure is high more, and the packing of finished product is high more, and the required press time is also short more.Press time is preferably 15-200 second, more preferably 30-150 second.Press time is too short, then is not easy compacting, and overlong time also there is no need.In order to improve product proportion, can increase pressing pressure and press time.If used adhesive is a thermohardening type, then under the situation of conditions permit, can in compacting, heat (being so-called hot pressing) to mould, saving the time of follow-up independent curing schedule, even can omit curing schedule.Hot pressing, normal temperature cure or be heating and curing is the optional step in the method for the present invention, and in case of necessity, those skilled in the art can select at least one step in these optional steps with the characteristic of adhesive and curing agent according to selected metal.
This mould can have reservation shape.Here in fact said reservation shape should depend on required shape of product or structure.If final products are dumbbells, then this mould is a dumbbell shaped.If final products are dumbbell heads, then this mould is the dumbbell head.In a word, this mold shape is not subjected to specific limited.But with regard to the difficulty and the manufacturing difficulty or ease of mould of compacting, mold shape is simple more good more, therefore, this manufacture method is particularly suitable for making the product of simple shape, for example dumbbell head, disc (dish), mass (for example the mass of simple shapes such as bulk, strip generally is used to increase training strength) etc.Mould with this type of shape of product is made usually easily, and compacting easily.Certainly, in order to make the identical product of different size, also can select the mould of the different size that is used to make identical product for use
The dumbbell head that makes can be installed on the dumbbell handle according to method well known in the art (for example rotation fixing etc.), thereby constitutes dumbbell.Disc and mass also can use by its intrinsic purposes.
After compacting, can obtain in type semi-finished product.
If used adhesive is quick-setting adhesive, then these semi-finished product do smooth slightly or dry after carry out certain surface treatment as spray paint, encapsulate technology etc., can come into operation.That is, manufacture method of the present invention also can not comprise independent curing schedule.In other words, independent curing schedule is not essential, but can merge with pressing step.
If but used adhesive is the adhesive that needs normal temperature slowly to solidify or need be heating and curing, and then also need implement curing schedule.In order to save the energy, described curing schedule can be implemented at normal temperatures, and be 1 hour to 24 hours general hardening time, depends on the different of adhesive and curing agent, also can be 24 hours to 48 hours.But if enhance productivity, also can be heating and curing, baking and curing for example, this moment, used solidification temperature was generally 60-200 ℃, and be 20 minutes to 180 minutes hardening time.In addition, according to actual conditions, normal temperature cure and being heating and curing also can be used in combination, and for example, is heating and curing earlier, places it under the room temperature cooling again and solidifies, and vice versa.When practical operation, those skilled in the art can adjust these process conditions according to the different instructions for uses of adhesive therefor and curing agent, solidify fully as long as can guarantee final products.In general, commercially available metal is all pointed out using method by supplier with adhesive and curing agent, and the producer only needs to select suitable bonding and curing agent to get final product according to existing equipment condition and final purpose.
In any case,, can above-mentioned each process conditions be adjusted under the prerequisite of main idea of the present invention in order to obtain to have the product of required specification.For example, can drop into a certain amount of raw material, thereby obtain to have the product of predetermined weight specification according to the requirement of final products.
In addition, can also carry out post processings such as for example plastic or rubber-coated overcoat to the product that makes by method of the present invention according to final purpose.Though this type of is slightly had any different with product of the present invention through on the product profile of post processing, because of it possesses all technical characterictics of the present invention, so also within the scope of protection of present invention.
The density of the actual product that makes of the present invention can reach 3.0g/cm
3To 6.5g/cm
3, compare with the density of cement or concrete product, obvious lifting is arranged.Therefore, small product size of the present invention can be dwindled greatly.
On the other hand, gained dumbbell head and disc product have intensity height, good toughness, rustless characteristics, compare with traditional foundry goods, have improved the utilization rate of material, have reduced the pollution to environment, have saved the energy, and cost is low, the product surface quality height.For another example, existing rubber dumbbell, disc equally also exist problems such as the proportion small size is big, and owing to exist sulfuration process in process of production, cause serious environmental to pollute.Compare with the rubber dumbbell, the present invention has not only reduced the volume of product, and has reduced the pollution to environment.
Below with reference to embodiment, further set forth characteristics of the present invention and beneficial effect.
