| The difference between intermediate frequency pipe bender and intermediate frequency elbow machine
Medium frequency pipe bender is the main product of our company. It is mainly used to produce all kinds of large radius pipe bender and small radius elbow.The medium frequency pipe bender has the advantages of reasonable design, reliable operation, simple operation and good working performance.
The medium frequency pipe bender is divided into power system and transmission mechanism. The power system of the medium frequency pipe bender is made up of motor and reducer. There are two working states: fast advance and backward, respectively driven by AC motor and frequency conversion motor.Variable frequency motor is to provide the power into the elbow machine, AC motor is the brake and electromagnetic and AC motor linkage control.The transmission mechanism includes the wheel, chain, track and so on.
The method of making large radius pipe bending by medium frequency pipe bender is as follows: the pipe with the same diameter is heated by the induction ring using four-wheel intensified steel pipe. With the rotation of rocker arm, the pipe with the diameter is bent without mandrel and core head and without diameter expansion.
The method of pushing the elbow with a small radius is: the small diameter pipe is heated by the middle frequency induction ring through the mandrels and horn mandrels, and the elbow with a large diameter is expanded. Generally, we will choose the middle frequency elbow machine produced by our company in the production like this.
Correct Troubleshooting Method of Hydraulic Pipe Bender
Once the failure of the hydraulic pipe bender occurs, it will not only affect the production of the equipment itself, but also often affect the whole production system. In particular, once the failure of the production equipment on the automatic production line, it will often cause the paralysis of the whole production line, which will bring huge economic losses.Therefore, it is required that once the hydraulic pipe bender fails, it should be quickly and accurately diagnosed and quickly and conveniently eliminated with less disassembly and assembly as far as possible.Hydraulic faults involve complex factors, concealed fault points, and the causality of fault generation and development has the characteristics of time-varying, randomness, interlacing and overlapping, so it is difficult to diagnose and eliminate hydraulic system faults on site.
In order to save the time of troubleshooting, reduce the load of assembly and disassembly and avoid the adverse effects caused by assembly and disassembly, we must think about it, disassemble and check the hydraulic components and components one by one before and after, and should choose, focus on, check the internal condition of the hydraulic device in order.The fault diagnostics personnel need to infer the possibility of each fault cause based on the surface observation of hydraulic fault symptoms, according to the relevant criteria, and then according to the specific situation of the site, in order to make a more in-depth and detailed analysis and judgment of the hydraulic device.Therefore, the rationality of fault recovery and troubleshooting route can not be ignored.
Rapid diagnosis is carried out on the premise of correct diagnosis.In the hydraulic fault diagnosis, due to the influence of incorrect method and other factors, the situation of misdiagnosis or diagnosis can not reach a conclusion often happens.On the other hand, speed is only a relative concept, refers to the use of scientific and reasonable diagnosis method, can be diagnosed and eliminated at a faster speed of hydraulic fault.
To diagnose the fault of the hydraulic device, it is necessary to select the appropriate parameters as soon as possible at first, so as to determine the dividing line between the normal state and the fault state of the system through the investigation of these parameters.The second is through the appropriate way to quickly and reasonably obtain the relevant information, that is, how to correctly measure the relevant parameters.Because, only by selecting system parameters quickly and accurately, determining fault discriminant criteria and collecting information, can the purpose of rapid diagnosis and troubleshooting be realized.
Before the hydraulic pipe bender is formally put into use, it needs no load for time, so that it can be easy to find the operation of the machine. Pay attention to whether there is abnormal sound. If it is normal, it can be formally put into use, and the corresponding personnel should be reasonably arranged to operate.
Hydraulic pipe bender needs relevant personnel to supervise in the process of use, in order to solve problems in time and reduce the possibility of accidents.Hydraulic pipe bender in the work of the bent plate compaction, can not be warped or loose, so that the work will hurt the operator.If there is a problem, the user needs to disconnect the power supply before checking or adjusting. Personnel are strictly prohibited to stand at the back of the machine during the working process of the machine.
Operating specification of hydraulic pipe bender, hydraulic pipe bender as an important mechanical equipment for pipe processing in the current market, plays a very important role in the production and processing.With the development of industry, more and more users begin to use hydraulic pipe bender for processing. Therefore, it is very important to master and understand the operation specification of hydraulic pipe bender. This paper will briefly introduce the matters needing attention when the user operates.
As a kind of metal processing machinery, general meeting is dangerous, so the correct operation of hydraulic pipe bender can avoid many accidents, increase of mechanical equipment, hydraulic pipe bender before using the user need to check the function of the parts, such as motor, switch, and the place such as line, check whether the parts is firm and the presence of loose condition, if has the need to immediately take the corresponding solutions.
