Application scope of crimping machine and how to classify

Application scope of crimping machine and how to classify

Application scope of crimping machine and how to classify The crimping machine firmly crimps the metal joints on the matched high-pressure oil pipes for construction machinery or the brake pipes, engine oil pipes, air-conditioning pipes, and power pipes of the automobile. The crimping machine is suitable for the crimping of various mechanical high and low pressure oil pipes, air pipes, water pipes, cable joints, automobile air conditioning pipes, automobile power steering pipes, engine oil pipes, gasoline supply pipes, as well as construction accessories and daily hot water pipes. It is widely used Vehicles, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. The crimping machine is suitable for the crimping of various mechanical high and low pressure oil pipes, air pipes, water pipes, cable joints, automobile air conditioning pipes, automobile power steering pipes, engine oil pipes, gasoline supply pipes, as well as construction accessories and daily hot water pipes. It is widely used Vehicles, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. According to the function of use, it can be divided into: hydraulic high pressure tube crimping machine, brake tube crimping machine, air conditioning tube crimping machine, power tube crimping machine, etc. According to the mechanical structure, it can be divided into: straight barrel crimping machine, double-column crimping machine, open type Crimping machine, C-type crimping machine. According to the control method, it can be divided into: electromechanical crimping machine, PLC crimping machine, and numerical control crimping machine. The manufacturer analyzes the causes of failures encountered in the use of the crimping machine in the hydraulic piping system of construction machinery: The hydraulic pipeline system of construction machinery is the power transmission system of the main engine of construction machinery, which can be described as the blood vessel of the whole machine. The quality problems of the hydraulic piping system of domestic construction machinery are mainly manifested in the oil leakage, oil leakage and cleanliness of the piping system, the product quality is not up to the standard, there are technical barriers, and it cannot be used for high-pressure vehicles.

Analyze the application principle and installation of the hose crimping machine

Analyze the application principle and installation of the hose crimping machine

Analyze the application principle and installation of the hose crimping machine The hose crimping machine is a hydraulic equipment used to withhold the hose fitting assembly. It applies the shrinking force to the matched metal joints through the mould of the hose crimping machine, and firmly crimping the metal joints on the matched high-pressure oil crimping for construction machinery or automobiles. On the brake pipe, oil pipe, air-conditioning pipe and power pipe. The thin tube pressing machine is suitable for all kinds of mechanical high and low pressure oil pipes, air pipes, water pipes, cable joints, automobile air-conditioning pipes, automobile power steering pipes, oil pipes, gasoline supply pipes, as well as construction accessories, daily hot water pipes. Used in industries such as vehicles, construction machinery, hydraulic machinery, welding and cutting equipment. The crimping machine manufacturer tells you the installation and use of the crimping machine: (1) Add enough 32-46# hydraulic oil 50kg at one time (preferably genuine original oil)   (2) Positioner installation: first insert the positioner into the front of the machine head (note: the positioner can be directly inserted into the machine head), and insert the other end plug into the corresponding socket inside the electric control box (3) Connect the power supply. If you are using a three-phase motor, be careful not to connect it in the reverse direction. (4) After the above procedures are completed, you can start the pressure test (5) The use of the positioner: press 1mm more for each half of the reverse rotation, 1mm less for each half of the forward rotation, and so on.

Analyze the use and precautions of the steel hose crimping machine

Analyze the use and precautions of the steel hose crimping machine

Analyze the use and precautions of the steel hose crimping machine The shrinking machine produced by the hose crimping machine manufacturer has a wonderful design in appearance. There are two stretch springs on both sides that can be extended. In order to solve the problem of leakage due to poor welding, the pipe shrinking machine is mainly planned and issued for the steel pipe crimping and locking requirements of the construction industry. It has no pollution, fast efficiency, small face, light weight, quick mold opening, and easy operation. 1. The principle of the steel pipe shrinking machine: through mechanical transmission, the steel pipe is driven to rotate, and one end of the steel pipe is heated with flame. When a certain temperature is reached, the heated steel pipe head is driven by a forming mold until it reaches the required shape until. 2. The structure of the steel pipe shrinking machine: Weld a site with channel steel, and the power end is equipped with a motor, a reducer, and a chuck (for pipe clamping, it can be replaced by a lathe chuck). A support base (openable) is installed at the other end, and a heating ring is fixed on the outer end of the support base (8-10 nozzles, welded to a copper pipe ring by gas welding). *On the outside is a movable bracket with an alloy mold installed on it. 3. How to use the steel pipe shrinking machine: fix the pipe on the pipe shrinking machine and turn on the heater (ring). After the temperature is reached, the alloy mold is pushed, and the shape of the tube head meets the requirements. The whole process takes about 15 minutes. Special equipment that is precisely clamped on the hose, such as (hydraulic machinery, injection molding machines, excavators, loaders, cranes, car air-conditioning pipes), is a necessary equipment for hydraulic machinery factories and excavator repair points.
