Why the crimping machine is selling well

Why the crimping machine is selling well More than 95% of current crimping machines use hydraulic systems, which are occasionally used in pressure-only low-pressure tubing crimping machines or sanitary pipe crimping machines that are powered by pneumatic systems or levers. The oil pump of the hydraulic system is equivalent to the human heart, and its role is very important. The gear pump is used as the power source of the crimping machine. It is often considered that its cost is lower, the cost is saved, and the cleanliness of the oil is not high-level elements, but its defects For: The supply pressure is low, only equivalent to 60% of the plunger pump pressure, the noise is large, and the service life is short. Due to the low supply pressure, manufacturers often consider sacrificing the expansion and contraction capacity of the crimping machine in order to increase the crimping pressure. 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. Because the reputation and reputation are good, the customer's evaluation to a certain extent represents the degree of product quality assurance, and the machine is good or not, the customer's evaluation is a very intuitive reflection. 1. The principle of dual hydraulic circuit operation is adopted, that is, the advance and retreat of the piston and the opening and contraction of the mold are all driven by the hydraulic power source. It not only moves smoothly and returns quickly, but also does not cause the mold to be locked due to the spring return. Moreover, the design of the cylinder locking system is through front and back, which is easy to withhold various special-shaped elbows. 2. The hydraulic system is composed of a motor, an oil pump, a solenoid valve, a pressure regulating valve and a hydraulic valve. The purpose of quick return, and the speed is adjustable, noise and system pressure are reduced. 3. In terms of electrical control system, the control circuit is suitable for PLC circuit, which is easy to check and repair the circuit, easy to maintain, and simple to replace. 4. The crimping mold and mold base adopt a non-accumulative error-free processing technology to ensure that the crimping lines of the product after crimping are evenly spaced, and there is no big or small head phenomenon. Using plunger pump as the power source of the crimping machine, the advantages are: 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: high 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.

Let customers understand the application advantages of hydraulic crimping machine

Let customers understand the application advantages of hydraulic crimping machine When the hose crimping machine crimps the high-pressure oil pipe, if the crimping amount is too small, then the pressure between the joint and the hose is too loose, under the action of the oil pressure, the crimping machine hose may come out of the joint at the early stage of use, if the crimping amount is too large , Then the joint and the hose are pressed too tightly, which will easily cause the inner layer of the hose to be partially destroyed and cracks. The hydraulic oil will directly enter the steel wire layer from the crack, and then leak out along the gap between the steel wires to the end of the outer jacket, or continuously along The steel wire layer flees somewhere and accumulates, causing the outer layer of glue to bulge and even break. From raw rubber plasticizing to break the macromolecular chain to make the molecular weight drop to achieve plasticity, and fully mix and average it with various compounding agents, to make high-elasticity and high-quality rubber pipes under the process conditions of heating and pressure. Throughout the process, we are striving to seek new technologies and techniques for hose processing to improve efficiency, improve quality, and reduce labor intensity. The new technology of hose processing requires a high degree of continuity, high speed and automation of the molding process, and the final qualified pipe can be produced in one molding. Advantages of hydraulic crimping machine: 1. It can be customized according to the needs of customers. 2. It can be used for forming different shapes of pipe fittings, automobile oil pipes, air pipes, water pipes, air-conditioning pipe connections and other parts. 3. It adopts hydraulic power, stable work, high rejection rate, low vibration, low noise, and the machine structure is solid, compact and easy to operate. In order to withhold the machine on the locking mechanism components, not only high-quality alloy steel materials are selected, but also a unique heat treatment process is adopted. Therefore, the longer service life of the crimping machine is inseparable from the rationality of material selection, heat treatment, mechanical processing technology and structure! Regarding the double-column crimping machine and C-type crimping machine, because it is not convenient to set the dead position, it is necessary to use the numerical control method to control the crimping size.
