What Are Quick Release Connectors? You need to read this

The quick-release fittings are also called a quick connector, which mainly causes the excavator to improve the replacement efficiency between the bucket and bucket and loose soil parts. It is divided into hydraulic and mechanical types. Although the design is very flexible and subjective, the basic principle is the same.

Introduction

Quick-release fittings is a wide range of industrial product accessories noun, divided into hydraulic pipeline quick release fittings and excavator quick-change joint. The quick replacement joint of the excavator is also called quick connector and quick connector. The quick replacement joint can quickly install various configurations (excavator, soil loosening device, crushing hammer, hydraulic shear, etc.) on the excavator, which can expand the use scope of the excavator, save time and improve work efficiency.

Structure and Production

The quick-change joint is a structural part type of product, composed of the main support, movable card block, hydraulic cylinder, pin shaft, and other parts. The production process of quick replacement joint includes unloading, vehicle, milling, drilling, forming, welding, grinding, sandblasting, spraying, assembly, etc. Quick replacement joint special industry equipment accessories, need special equipment to achieve high efficiency, high-quality operation, such as CNC plasma cutting machine, slope mouth milling edge machine, coil machine, welding transformer machine, boring machine, hydraulic test table, etc.

Hydraulic Quick-change Connector

Hydraulic quick-changing connector mainly fixed and releases pin axles 1 and 2 by cylinder action. When the case is necessary to replace the working parts, the cylinder is withdrawn, the hook pressure block moves from position 1 to position 2, and the joint is removed quickly, replaced with other working parts. After the hook pressure block pairs the pin shaft, the cylinder opens again, and the hook pressure block moves from position 2 to position 1 to lock the pin shaft of the working accessories. Of course, except that the external oil circuit and the solenoid valve work simultaneously.

Mechanical Principle

Mechanical quick replacement joint domestic manufacturers are mainly divided into two kinds, a plug type, a screw type. Take the plug-in type as an example, when the need to replace the working parts, the wedge card out, the T-shaped buckle into the knock, (T-shaped buckle can smoothly drive the red block to recycle, where the welding requirements are high, the rail welding smooth, while grinding the unclean point, the red block action is difficult to smooth.) The quick-change connector is away from the bucket. When replaced with the required working part, the T-buckle is pulled back and the wedge card is inserted into the T-buckle for the lock.

Connection Features

The quick-changing connector has the following advantages:

1. Rapid and convenient disassembly, save time to improve work efficiency and reduce the labor intensity of operators.

2. There is almost no working medium outlet when the self-sealed fast switch connector is disconnected. Reduce the pollution of the working environment and avoid dirt into the pipeline system, thus improving the reliability of the hydraulic system.

3. The quick changing joint itself can rotate freely, which not only releases the internal stress generated in the pipeline during the installation process but also overcomes the loosening caused by the vibration during work.

4. Use high-strength materials; suitable for various models of 3-45 tonnage.

5. Use the safety device of the liquid control check valve to ensure safety.

Joint Classification

Quick change joints are generally divided into mechanical quick-change joints and hydraulic quick-change joints

The mechanical quick-change joint can be used without modifying the excavator line and hydraulic system (low-cost type); the hydraulic quick-change joint needs to modify the excavator line and hydraulic system to meet the requirements of automatic replacement working device.

Pneumatic Control

A high-speed rotary quick-change joint for pneumatic control is a quick and convenient connector designed to replace pneumatic elements in various industrial pneumatic automatic control fields. The built-in bearing can be freely rotated around the central axis for 360 degrees without damage, the basic material used: copper, the maximum gas pressure of 1.0Mpa, a vacuum system (vacuum degree below 100kPa), suitable for connecting hose material: nylon and PU, standard quick-changing joint with sealant, nickel treatment.

Quick Change Joint Effect

Fast replacement joint, mainly when the excavator improves the replacement efficiency between the bucket and loose working parts, is divided into hydraulic and mechanical types.

Quick Joint Action

A quick connector is a joint that can connect or connect without a tool. Quick joints can be divided into quick joints for air, quick joints for oxygen fuel gas, gas and liquid sharing, quick joints for oil pressure, quick joints for inert gas, quick joints for cooling water temperature, and semiconductor quick joints.
