Introduction to the crimping machine:

The English name of the crimping machine is usually translated as: crimping machine or crimping machine. A crimping machine is a hydraulic device used for crimping pipe fittings. It applies a contraction force to the metal joint through the mold of the crimping machine, firmly crimping the metal joint onto the high-pressure oil pipe for engineering machinery or the brake pipe, oil pipe, air conditioning pipe, and power pipe on the vehicle. The crimping machine is suitable for crimping various mechanical high and low pressure oil pipes, air pipes, water pipes, cable joints, automotive air conditioning pipes, automotive power steering pipes, oil pipes, gasoline supply pipes, as well as building accessories and daily hot water pipes. It is widely used in industries such as vehicles, engineering machinery, hydraulic machinery, welding and cutting equipment.

The classification of crimping machines can be divided into hydraulic high-pressure pipe crimping machines, brake pipe crimping machines, air conditioning pipe crimping machines, power pipe crimping machines, etc. according to their usage functions. According to their mechanical structure, they can be divided into straight tube crimping machines, double column crimping machines, open type crimping machines, and C-type crimping machines. According to their control methods, they can be divided into electromechanical crimping machines, PLC crimping machines, and CNC crimping machines. Among them, electromechanical crimping machines are widely used, and their advantages and technical performance are as follows:

1. Adopting the principle of dual hydraulic circuit operation, the piston’s advance and retreat, as well as the mold’s opening and contraction movements, all rely on the power generated by the hydraulic power source. It not only moves smoothly and returns quickly, but also does not experience the phenomenon of spring return, which makes the mold unable to open and lock. Moreover, the design of the oil cylinder locking system is front and rear through, making it easy to clamp various special-shaped elbows.

2. The hydraulic system consists of a motor, oil pump, solenoid valve, pressure regulating valve, and hydraulic valve, forming a dual hydraulic oil circuit with forward and backward movement. In addition, a quick release valve oil circuit is added to the dual hydraulic oil circuit to achieve faster return, with adjustable speed, reduced noise, and system pressure.

3. In terms of electrical control systems, the control circuit is suitable for PLC circuits, which are easy to maintain, convenient to repair, and easy to replace.

4. The crimping mold and mold base adopt a zero cumulative error processing technology to ensure that the crimping lines of the product are evenly spaced and free of large and small head phenomena after crimping.

5. In order to ensure the permanent mechanical accuracy and service life of the clamping machine, not only high-quality alloy steel materials are selected for the locking mechanism components, but also a unique heat treatment process is adopted. So the longer service life of the press machine is closely related to the rationality of material selection, heat treatment, mechanical processing technology, and structure!
