Introduction of Clamps

A clamp is a fastening device used to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. Key specifications include clamp type, grip rang and the clamp features. Hand tool clamps are applied in various fields, such as metallurgy, transportation, railway, port, etc . For general workholding, the common types include Bar clamps, C Clamps, F Clamps, Pipe Clamps, Spring Clamps and others. There are some special types of clamps, which include hold down clamps, 90 degree angle clamp, along with edging clamp. Selecting hand clamps is mostly a matter of identifying the clamp type or application. Bar clamps, are useful for gluing up laminated assemblies. Pipe clamps are generally specified by diameter. Manufacturers usually choose economy and installation ease when selecting clamps, whereas do-it-yourselfers might spring for costlier clamps that don’t require special tools for installing.

Judge Wrench Quality from The Surface

Wrenches have too many brands, different brands have a unique advantage, so consumers to face the choice of wrench. How to choose a cost-effective wrench?
1.Punching
Wrench punching part of the hole should be rounded and smooth, no holes within the hole, no knife marks and other phenomena, and shake hands should be rounded, no burrs, otherwise it will affect the user experience.
2.Surface treatment
Wrench surface treatment has a variety of ways, most high-grade is water mist treatment. In fact, when buying wrenches can also be judged from the above specifications, high-quality wrench logo and specifications are very clear, the font uniform.
3.Thickness
With the specifications of the wrench, the smaller the thickness, the lighter the weight, the more users can feel comfortable, so the quality is better.
High-quality wrenches in all aspects of the specifications are qualified, wrench manufacturers should strictly control the quality, so that it is worth the trust of consumers. And consumers to buy a professional wrench, should also be appropriate for its maintenance, it will not reduce its life.

Diamond Saw Blade Classification According to Appearance

1.continuous edge saw blade: it generally produced by sintering method, commonly used bronze binder as the basis of carcass material, cutting need to add water ensure that the cutting effect, and useful laser cutting the gap will be the type of knife.
2.sub-tooth blade-type saw blade: jagged disconnected, cutting speed, suitable for dry and wet cutting methods.
3.the turbine saw blade: The saw tooth continuously exhibits a turbine-like concavity, which improves the cutting speed and increases the service life.
Different materials use different types of diamond saw blade, different powder formula for different material properties, it has a direct impact on the quality of the material products, the results, the pass rate and even the cost and effectiveness.

How to Buy Caulking Guns Correctly?

As the current market has many styles and types of caulking gun products, people have a dazzling feeling in the selection, many people do not know how to make a choice, so as to bring the impact of people's lives inconvenience.
First of all, people need to go to a regular sales store or a large store to buy products, only so that we can pick out the most quality assurance of caulking gun products for their own use. So that we can get the greatest satisfaction.
Second, the cement caulking guns should be purchased according to their own needs, the purchase of caulking guns are determined by the actual needs of individuals. Finally, need to purchase affordable cement caulking gun, in order to get the best product performance effects.

What Is the Hammer Drill?

A hammer drill is a drill with a specialized “hammer” mode, it can be used to drill into masonry such as brick, cement, and similar materials. The hammer mode can often be turned off so that the drill can be used as an ordinary drill. The hammer drill capabilities do add a little to the weight.
Hammer drill can drill into masonry and anything else a non-hammer drill can work. It has adjustable clutch to match power with application and fastener size, drill chuck that can accept wide variety of bit styles and sizes, it is well to suit for drilling holes and driving fasteners.

The Application Scope of Stamping Parts

Stamping parts compared with castings, forgings, it has a thin, light, strong features. Punches parts suppliers can produce ribs, ribs, undulating or flanging of the workpiece by other difficult methods to improve its rigidity.
As a result of precision molds, the workpiece accuracy of up to micron level, and repeat high precision, consistent specifications, you can punch out the hole nest, convex and so on. In the actual production, commonly used with the stamping process similar to the process test, such as drawing performance test, bulging performance test materials such as stamping performance to ensure the finished product quality and high pass rate.

The Characteristics of Punches

Stamping parts are mainly metal or non-metallic sheet, with the pressure of the press, stamping processing though the stamping die, here are some characteristics of punches.
(1)stamping parts in the material consumption is not under the premise, stamping produced by the parts of its weight light, good stiffness, and the sheet after plastic deformation, the internal structure of the metal is improved, so that the strength of stamping parts increased.
(2)stamping parts with high dimensional accuracy, uniform size with the same module, a better interchangeability. Further mechanical processing can meet the general requirements of the assembly and use.
(3)stamping parts in the stamping process, because the surface of the material from damage, it has a better surface quality, the appearance of smooth and beautiful, which for the surface painting, plating, phosphating and other surface treatment provides a convenient condition.
