Crimping MachineWhat is the manufacturing method of the pressing head?
This utility model relates to a pressing head for pressing pipe fittings, especially a pressing head for pressing hose assemblies, belonging to the technical field of hydraulic pressing machinery. So what is the manufacturing method of the crimping machine's pressing head?
What is the manufacturing method of the crimping machine's pressing head?
1. The press is a machine used for assembly pressing, applying shrinkage force to matching metal joints through a die, firmly pressing the metal joints onto the matching hose. This press is suitable for pressing various machines' high and low-pressure hoses, gas pipes, water pipes, cable joints, air conditioning pipes, etc., and is widely used in industries such as vehicles, construction machinery, household appliances, welding, and cutting equipment. Currently, the requirements for the press are not only high precision and efficiency but also the ability to press various forms, diameters, and layers of elbows, flanges, and large-diameter hose assemblies, which imposes stricter requirements on the press.
2. Currently, the molds used for pressing the machine head are generally fixed or embedded in the body, with a narrow application range, only able to press joints of general sizes, especially oversized elbows. Moreover, the supporting springs in the mold pressing seat may deform due to fatigue after long-term use, leading to asymmetrical spacing between the mold pressing seat and the mold, resulting in poor fastening effects.
3. It often requires changing or adjusting the tension of the supporting springs on the mold pressing seat to achieve symmetry in the distance between the mold pressing seat and the mold, which is very inconvenient to use. Additionally, the pressing block of the existing press is installed on the machine head seat, generally requiring 2-4 hydraulic cylinders with piston push rods to push the pressing block for working motion, and also needing 1-2 auxiliary small cylinders with pistons and piston rods to push the pressing block for return motion; furthermore, in the existing pressing heads, a reset spring is used to push the pressing block for reset motion. The existing pressing heads are not only complex in structure and large in size but also have high resistance during the working of the pressing block.
4. After the hose joint is clamped by the mold inside the pressing head, it is easy to lock when the pressing block is pushed back by the spring. In addition, the existing pressing head has only one inclined surface for the pressing seat, and its pressing block has only one inclined surface corresponding to the pressing seat's inclined surface. During pressing, when the pressing block moves forward (axially) under the pressure of hydraulic oil from several oil cylinders, the corresponding units of the mold pressing seat slowly move towards each other (radially) through the action of their inclined surfaces and the inclined surface of the mold pressing seat, affecting work efficiency.
The above is the relevant knowledge compiled for you by the editor,Crimping Machinethe pressing head is still produced by professional manufacturing factories. The crimping machine is used relatively less in daily life, but in some industrial productions, the extruder is an indispensable model. I hope the content compiled by the editor can help you!
