AI Technical Summary

Problems solved by technology

These existing withholding machine heads not only have the disadvantages of complex structure and large volume, but also have the large resistance of the extrusion block when it is working, and when the mold in the crimping head has crimped the rubber hose joint, it will be closed by the spring tension. The disadvantage that it is easy to lock when pushing the extrusion block back to its position
In addition, the mold extrusion seat in the head of the existing crimping machine has only one slope, and the extrusion block also has only one slope corresponding to the slope of the mold extrusion seat.
When crimping, when the extrusion block moves forward (axially) under the pressure of the hydraulic oil of multiple cylinders, through the action of its slope and the slope of the die extrusion seat, the corresponding units of the die extrusion seat are very slowly facing each other ( Radial) movement, which greatly affects the work efficiency

Embodiment Construction

[0017] Embodiments of the present invention: as attached figure 1 As shown, it is composed of an oil cylinder 1, a front end cover 2, a rear end cover 3, an extrusion block 4, a mold extrusion seat 5 and a mold 6. They are respectively connected to the front end and the rear end of the oil cylinder 1, a chute 9 is provided on the sloped surface of the front end cover 2, and a chute 10 is provided on the mold extrusion seat 5, and the mold 6 is connected to the mold through the mold screw 7. On the extrusion seat 5, the mold extrusion seat 5 is connected to the front end cover 2 through a screw 8, wherein one end of the mold screw 7 is inserted in the chute 10, and one end of the screw 8 is inserted in the chute 9, and the screw 8 is T-shaped screw, mold screw 7 and T-shaped screw 8 can slide along the chute 10 and chute 9 respectively. Since the end face of the front end cover 2 is a pot-shaped slope with a certain slope, the mold extrusion seat 5 can be combined with the mold...

Abstract

A working head of die press is composed of a cylinder, the front and back end covers connected respectively to the front and back ends of said cylinder, the die holder connected to said front end cover via screws, die connected to said die holder via screws, and pressing block installed in said cylinder and arranged between said die holder and back end cover. Its advantages are no oil leakage, high pressure and long service life.

Description

Technical field: [0001] The invention relates to a head of a crimping machine used for crimping a pipe fitting assembly, in particular to a head of a crimping machine used for crimping a rubber hose assembly, and belongs to the technical field of hydraulic crimping machinery. Background technique: [0002] The crimping machine is a machine used for crimping the pipe fitting assembly. It applies shrinkage force to the matching metal joint through the crimping machine mold, and firmly crimps the metal joint on the matching rubber hose. The crimping machine is suitable for crimping various mechanical high and low pressure hoses, air pipes, water pipes, cable joints, and air-conditioning pipes. It is widely used in industries such as vehicles, construction machinery, home appliances, and welding and cutting equipment. At present, not only the crimping machine is required to have high precision and high efficiency, but also to be able to crimp elbows, flanges, ultra-high pressure...
