Wandres hose connectors Germany Wandres model Wandres price

Wandres hose connector is a type of connector that allows connection or disconnection of pipelines without tools. Exchange function: accessories for pneumatic and hydraulic tools, cylinders, hydraulic cylinders, and machinery related to metal molds. Maintenance function: cooling devices for computers, maintenance of oil cylinders in die-casting machines. Test function: testing for vacuum, pressure resistance, leakage, operation, etc. Conveying function: conveying and handling of solids such as bolts and nuts, as well as electrical conductivity. Filling function: inert gases, nitrogen, PG, carbonic acid. Time and labor saving: when disconnecting and connecting oil lines via quick connectors, the action is simple, saving time and manpower. Oil saving: when the oil line is disconnected, the check valve on the quick connector can close the oil line, preventing oil from flowing out and avoiding loss of oil and oil pressure. Environmental protection: when quick connectors are disconnected and connected, oil does not leak, protecting the environment. Equipment modularization for convenient transport: large equipment or hydraulic tools that need to be portable can be disassembled using quick connectors for transport, and then assembled for use upon reaching the destination.

Wandres hose connector process flow

Stamping forming: Stamping forming elbows were the earliest forming process applied to mass production of seamless elbows. In the production of common specification elbows, it has been replaced by hot pushing or other forming processes. However, for certain specifications with small production quantities, excessively thick or thin walls, or special product requirements, it is still in use. The stamping forming of elbows uses pipe blanks with an outer diameter equal to that of the elbow, which are directly pressed into shape in a mold using a press. Before stamping, the pipe blank is placed on the lower die, the inner core and end die are inserted into the pipe blank, and the upper die moves downward to start pressing. The elbow is formed through the constraint of the outer mold and the support of the inner mold. Compared with the hot pushing process, the appearance quality of stamping forming is inferior. During the forming of stamped elbows, the outer arc is in a stretched state, and there is no excess metal from other parts to compensate, so the wall thickness at the outer arc is reduced by approximately 10%. However, due to its suitability for single-piece production and low cost, the stamped elbow process is mostly used for small-batch, thick-walled elbow manufacturing. Stamped elbows are divided into cold stamping and hot stamping, and the choice between cold or hot stamping is usually based on material properties and equipment capabilities. The forming process of cold-extruded elbows uses a dedicated elbow forming machine. The pipe blank is placed in the outer mold, and after the upper and lower molds are closed, the pipe blank moves along the gap reserved between the inner and outer molds under the push of the push rod, completing the forming process. Elbows manufactured using the inner and outer mold cold extrusion process have a beautiful appearance, uniform wall thickness, and small dimensional deviations. Therefore, this process is mostly used for forming stainless steel elbows, especially thin-walled stainless steel elbows. This process requires high precision for the inner and outer molds and has strict requirements for the wall thickness deviation of the pipe blanks.

Wandres hose connector manufacturing process

The forming of tee joints involves flattening a pipe blank with a diameter larger than that of the tee to approximately the size of the tee diameter, and opening a hole at the branch pipe stretching area. The pipe blank is heated, placed in a forming mold, and a punch for stretching the branch pipe is inserted into the pipe blank. Under pressure, the pipe blank is radially compressed. During radial compression, metal flows toward the branch pipe direction and forms the branch under the stretching of the punch. The entire process forms the tee through radial compression of the pipe blank and stretching of the branch pipe area. Unlike hydraulic bulging tees, the metal of the tee joint branch is compensated by the radial movement of the pipe blank, so it is also called the radial compensation process. Since the tee is pressed after heating, the tonnage of equipment required for material forming is reduced. Hot-pressed tees have wide adaptability to materials, suitable for low-carbon steel, alloy steel, and stainless steel. Especially for large-diameter tees with thicker walls, this forming process is commonly used.

Wandres hose connector classification

Pipe fittings come in many varieties. Commonly used pipe fittings can generally be divided into hard pipe fittings and hose fittings. If classified according to the connection method between the fitting and the pipe, hard pipe fittings include flared, ferrule, and welded types, while hose fittings are mainly crimped hose fittings. Pipe fittings are components in hydraulic systems that connect pipelines or install pipelines onto hydraulic elements. They are a general term for connectors that can be installed and removed in fluid passages. Types of pipe fittings include: end straight connectors, straight connectors, tee connectors, elbows, connectors with live nuts, swivel connectors, plugs, transition connectors, double ferrule connectors, etc.
