How To Choose Crimping Machine Products From Many Aspects

How To Choose Crimping Machine Products From Many Aspects The crimping machine is a combination of various engineering machinery, forming a device that integrates multiple purposes, and realizes one machine with multiple functions. The products on the market are good or bad, and so are the crimping machines. So when choosing a crimping machine, how do you choose a high-quality crimping machine? Here, the crimping machine manufacturer recommends three tips for everyone. Helped. Look: Observe visually whether the hydraulic accessories and electrical components selected by the crimping machine are brand-name products or are produced by regular manufacturers; whether the circuit configuration is regular; whether the design of the oil station piping is reasonable; whether there is oil leakage at the connection. If the above passes the visual inspection, you can proceed to the next step. Listen: Turn on the device after connecting it to the power source, and listen to whether the device's operating sound is normal. If there is abnormal noise, it is usually caused by the installation coaxiality of the motor and the oil pump. Another possibility is caused by the unreasonable selection of the oil pump displacement and pipe diameter, and the quality of the selected motor or oil pump. Not very well caused. Measurement: measure the main parameters of the equipment after Z Keep the crimping machine equipment in a dry running state, touch each module block with your hand, and there should be no jitter in the hand, otherwise it will be regarded as a substandard product. Install the crimping machine equipment on the mold, crimp a sample joint, measure the crimping joint with a caliper or a micrometer, the roundness and taper should be buckled within 0.1mm, which is considered excellent. The hardness of the mold base and the mold hardness are also the key to the normal use of the equipment in the future. Customers can request manufacturers to use a desktop or portable hardness tester to test the mold base or mold. When the hardness of the mold base is lower than Rockwell HRC60 and the mold hardness is lower than Rockwell HRC50, it will affect the withholding quality of the hose. After Z, it is to inspect the uniformity of the eight petals of the mold base of the equipment and the flushness of the mold. Good equipment will specifically control and adjust these two parameters, while some low-quality equipment does not control the above two parameters.

How To Choose The Right Crimping Machine

How To Choose The Right Crimping Machine More than 95% of current crimping machines provide power sources using hydraulic systems, which are occasionally used in low-pressure hose crimping machines or sanitary hose crimping machines that use pneumatic systems or levers to provide power. The oil pump of the hydraulic system is equivalent to the human heart, and its role is very important. Choosing gear pumps as the power source of the crimping machine often considers its low cost, cost-saving, and low requirements for oil cleanliness, but its shortcomings To provide a lower pressure, which is only equivalent to 60% of the pressure of the plunger pump. It is noisy and has a short lifespan. Due to the lower supply pressure, manufacturers often consider sacrificing the expansion and contraction capacity of the crimping machine in order to increase the crimping force. Improve the conversion of axial force and radial force of the crimping machine, so it is often possible to choose a gear pump crimping machine when the customer's requirements are not high. Using plunger pump as the power source of the crimping machine has the advantages of providing high pressure (300kg/cm2), long pump life, low noise, such as YCY series can automatically variable fuel supply, low pressure large flow, high pressure small flow, the same specifications The motor saves 30% of electricity and the hose that is crimped is not easy to leak oil. Because the system is high, it can be designed to achieve a larger opening under the same crimping pressure, so that customers can use it for a long time. But its disadvantages are: higher cost, the same displacement pump, the plunger pump is 8-10 times that of the gear pump, which increases the cost of a single machine, and requires relatively high oil cleanliness, but considering the basic performance Input-output ratio, choosing YCY system variable pump crimping machine will be very cost-effective.

Is there a limit to the crimping hose diameter of the crimping machine?

Is there a limit to the crimping hose diameter of the crimping machine? The crimping machine is an important auxiliary machine of the hose braiding machine, which is used in general hose production. It can effectively solve the problem of hose fitting sealing. The working principle of the crimping machine is to use high-strength liquid pressure to physically deform the connecting part of the hose fitting, so that the metal sleeve on the outside of the hose and the inner tube core are tightly combined, so as to achieve the function of sealing and leakproofing. Each crimping machine has restrictions on the diameter of the crimping pipe and the size of the nut. Generally speaking, the hose diameter suitable for the crimping machine is below 10cm. For the hose above 10cm, the crimping type hose connection is generally no longer used. Most of them are connected by hoop. Withholding range, the conventional is 6-51mm, withholding hose diameter 6-51mm spot supply is exported to the country's largest sales of 1.5 inch hose crimping machine, 2 inch hose crimping machine. Suitable for all kinds of mechanical high and low pressure oil pipes, air hoses, water hoses, cable joints, automobile air conditioning hoses, automobile power steering hoses, oil hoses, gasoline supply hoses, as well as construction accessories, daily hot water hoses, widely used in vehicles, High-pressure tubing presses, high-pressure tubing presses, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. When the user is crimping the high-pressure hose, if the crimping amount is too small, and the pressure between the joint and the hose is too loose, the crimping hose may come out of the joint at the beginning of use under the action of oil pressure. If the crimping amount is too large, then If the joint and the hose are pressed too tightly, it is easy to cause local damage to the inner layer of the hose, causing cracks. The hydraulic oil will directly enter the steel wire layer from the rupture, and then leak out along the gap between the steel wires to the end of the outer jacket, or continue along the steel wire layer. It accumulates somewhere, causing the outer layer of glue to bulge or even break. When crimping, the crimping speed should not be too fast, which will easily cause damage to the inner rubber and breakage of the steel wire layer, which will damage the hose prematurely during use. In actual work, when replacing the high-pressure hose, the length of the selected hose, the number of steel wire layers, the shape and size of the joint should be reasonable, and the degree of bending of the hose should be minimized. Most of the damage of the high-pressure hose is caused by improper production. .
