Talking About Bending Machine Equipment 返回首页

Everyone knows that the Pipe Bender Machine and the pipe expander machine are the most common type of machine in our life. The pipe expander machine processes the thin pipe into a thicker pipe by different processes. This machine is called a pipe expander machine. Weigh the heat pipe expander machine. The pipe bending machine, as its name implies, is mainly used to bend an object, mainly used for electric power construction, public railway construction, boiler laying, bridge, ship, furniture, decoration, etc., with many functions and reasonable structure. The advantages of simple operation. The pipe bender machine reduces labor costs in the traditional mode and greatly improves work efficiency. We can't do without bender products around our lives. For example, the office seats we go to work need to use pipe bender machines where there are pipes bent, especially in the industrial field, bend pipes are widely used. Important parts. So what is the standard for the bending machine equipment? As a Hydraulic Press Wholesaler, we believe that we can make a professional answer:


Hydraulic Pipe Testing Machine


Hydraulic Pipe Testing Machine


First, the parts are complete and complete, the quality meets the requirements


1 The main drive and auxiliary system parts are complete and complete, the hydraulic system has no leakage, complete accessories, and the quality meets the technical requirements.

2 Pressure gauge, oil mark and pressure relay are sensitive and reliable, and the oil quality meets the technical standards of hydraulic oil.

3 The body and the foundation foot are firmly connected without looseness.

4 The oil pipeline system has reasonable pipeline layout, no bruises, and the hydraulic parts are sensitive and reliable.

5 The equipment protective paint does not fall off, the exposed surface is neat, and there is no grease and no yellow robe.


Second, the equipment is operating normally and has good performance


1 Under the rated load condition, the relay protection system is sensitive and reliable, and reaches the nameplate output standard.

2 The equipment is well lubricated, the oil passage is smooth, the oil quality meets the technical requirements, the lubrication is fixed, and the oil is filtered in three stages.

3 All the gears in the gearbox of the machine tool are sealed with splash and the other parts are dispersed and single-point lubricated.    


Third, the technical information is complete and accurate


1 Equipment files, maintenance records, acceptance records are complete, fill in timely and accurate, installation test records, troubleshooting records are intact.

2 When the equipment is running, the statistics are accurate, the operation record is complete, there are reasonable operating procedures, and the equipment maintenance and repair procedures are carefully implemented.

3 Technical specifications, consumable parts drawings are complete, and there are assembly drawings that meet the maintenance needs.


Fourth, the equipment and environment are neat and clean


1 The environment is clean and tidy, no dripping or leaking. When the work stops, the tools and the tires return to their original positions.

2 There are prescribed safety passages, and the accessories are arranged neatly and reasonably.


So what is the standard for the bend radius of the bend?


First of all, one tube and one mold, for a tube, no matter how many bends, regardless of the bending angle (not greater than 180 °C), the bending radius is preferably uniform. Since one tube is a mold, what is the appropriate bending radius for pipes of different diameters? The minimum bending radius depends on the material properties, the bending angle, the allowable amount of thinning outside the curved wall and the size of the inner wrinkles, and the ellipticity at the bend. In general, the minimum bend radius should not be less than 2 to 2.5 times the outer diameter of the tube. For the duct of an aircraft or an engine, since the various pipes are traversed in a limited space inside and outside, the bending radius of the pipe is preferably small. The small bending radius makes the shape of the tube change flexible and adaptable. For large diameter engines and large aircraft, a slightly larger bend radius can be chosen with a looser piping arrangement. Because the large bending radius facilitates bending, it is advantageous for the elbow.


Secondly, the multi-tube model, the so-called multi-tube and one-die, is that the same diameter pipe should use the same bending radius. That is, using the same set of molds to bend different shapes of the tube shape. In this way, it is beneficial to minimize the compression of special process equipment and reduce the manufacturing cost of the bending mold, thereby reducing the production cost. In general, pipes of the same diameter are only required to have an assembly radius that does not necessarily meet the actual position. Therefore, pipes of the same diameter can be selected from 2 to 4 bending radii to meet actual needs. If the bending radius is 2D (where D is the outer diameter of the tube), then 2D, 2.5D, 3D, 4D can be used. Of course, the ratio of the bending radius is not fixed and should be selected according to the actual situation of the aircraft or the engine, but the radius should not be too large. The specification of the bending radius should not be too much, otherwise the benefits of multi-tube and one-mode will be lost.


Finally, our company specializes in the production of pipe bending machine, CNC pipe bending machine, Hydraulic Pipe Testing Machine, automatic pipe bending machine and other equipment, sincerely welcome new and old customers to visit us, we will be happy to provide you with a full range of services.
