How to use a hose crimping machine ?

Using a hose crimping machine involves several steps to ensure a secure and effective crimp on the hose.

We should first do some preparation work. We need to first add hydraulic oil that meets the requirements to the machine after we purchase a new hose crimping machine and receive it. Because usually machines are not allowed to contain oil during transportation.

After adding oil, the next step is to connect the power supply. Before connecting power, it is necessary to ensure that the connected power supply is consistent with the power supply format marked on the machine nameplate.Otherwise, there is a risk of damaging the machine.

Please read the machine’s user manual carefully before carrying out specific operations.

So we can proceed with the operation.

Here’s a general guide:

1.Confirm diameter

Before crimping, we must know the diameter we want to crimp. Generally, machines are labeled with a reference table for crimping dimensions. But that's just a reference. The same hose with joints from different manufacturers will have different crimping dimensions.

2.Select the Correct Die

Begin by selecting the appropriate die for the hose and fitting combination you are using. Dies are typically labeled with sizes that correspond to the hose and fitting size.

3.Insert the Die into the Crimper

Place the chosen die into the crimper. Make sure it is securely fastened and aligned correctly. If using our crimping machine, there is a mode specifically designed for mold replacement in our operating mode. Cooperate with specialized tools

4.Prepare the Hose and Fitting

Cut the hose to the desired length, ensuring the cut is clean and straight. If necessary, clean the end of the hose to remove any debris.Insert the fitting into the end of the hose. Depending on the type of hose and fitting, you may need to lubricate the fitting or use a tool to start the insertion process.

5.Position the Hose in the Crimper

Place the hose and fitting into the crimper, aligning the fitting with the die. The part of the fitting that needs to be crimped should be entirely encased by the die.

6.Crimp the Hose

Activate the crimper according to its design (manual, hydraulic, or electric). Apply enough pressure to crimp the fitting onto the hose securely. The crimper will typically have a gauge or indicator to show when enough pressure has been applied.

7.Inspect the Crimp

After crimping, inspect the hose to ensure the fitting is securely attached. There should be no gaps between the hose and the fitting, and the crimp should be evenly compressed around the circumference.

8.Test for Leaks

If possible, test the hose under pressure to ensure there are no leaks at the crimped connection.

At the beginning, there was no device to adjust the crimping diameter of the crimping machine. The electronic control system was not perfect enough, and the opening and close of the machine relied on a manual directional valve to complete it. Therefore, operators can only rely on their accumulated experience to confirm whether the crimping is in place by listening to the sound or observing the value of the pressure gauge. It can be imagined how difficult it is for beginners to crimp an assembly. Moreover, the qualification rate of the products after crimping is not high. Causing significant waste of resources.

With the continuous development and progress of hose cirmping machines.Getting started in the crimping industry is relatively simple.

Now, machines are equipped with displacement sensors, and the accuracy of crimping has been greatly improved. There are also multiple operating modes available at the same time. Beginners can also find the most suitable operating mode for it. Some can also be optionally equipped with a touch screen operating system. It has more functions. Its biggest advantage is that it can store the crimping data. And it can also be highly customized, allowing it to work with robotic arms for higher efficiency. It also supports integration into MES systems. Make its working status more visually displayed.
