Abstract
The utility model relates to a fastening oil cylinder for a cold header die holder. The fastening oil cylinder comprises a step motor (1), a threaded sleeve (4) and an oil cylinder (5); an oil cylinder rod (51) of which the two ends extend out of the oil cylinder (5) is transversely mounted inside the oil cylinder (5); a T-shaped pressing plate (6) is mounted at one end of the oil cylinder rod (51), while the threaded sleeve (4) sleeves the other end of the oil cylinder rod (51); the threaded sleeve (4) is tightly fitted with one end of the oil cylinder (5); a gear II (7) is mounted circumferentially on the threaded sleeve (4) and connected to an external gear I (2); the gear I (2) is connected with the step motor (1) through a rotating shaft. The fastening oil cylinder is simple in structure; the oil cylinder is capable of holding down the die holder in the quick die replacing process of the cold header and preventing the die holder from becoming loose.
Description
Technical field
The utility model relates to mechanical type tightening oil cylinder field, particularly relates to a kind of tightening oil cylinder for cold header die holder.
Background technique
Quick die change is by the product mould replacing time of mould, produces a kind of process improvement method that starting time or adjustment time etc. reduce as far as possible, it is the important content of lean production, for high-speed and high-efficiency ramming machine, quick die change can improve the absolute growth rate of effective working greatly.The quick die change of general large-tonnage ramming machine die holder is to complete by oil cylinder, and the dismounting of the die holder of Multi-station full-automatic cold header quick die change system compression completes by high-voltage oil cylinder.Because the operating conditions of Multi-station full-automatic cold header is to the continuous repeated impacts of the long high speed and high pressure of die holder, under this condition, be easy to cause loosening to oil cylinder of die holder, this just need to improve the reliability of oil cylinder tightening die holder.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of tightening oil cylinder for cold header die holder, simple in structure, and oil cylinder can compress die holder in cold header quick die change process, avoids die holder to produce loosening phenomenon.
The utility model solves the technological scheme that its technical problem adopts: a kind of tightening oil cylinder for cold header die holder is provided, comprise stepper motor, swivel nut and oil cylinder, described oil cylinder inner transverse is equipped with the cylinder rod that stretch out outside oil cylinder at two ends, T-shaped pressing plate is equipped with in described cylinder rod one end, the other end is socketed with swivel nut, described swivel nut and oil cylinder one end are closely affixed, described swivel nut is circumferentially provided with gear II, described gear II external gear I, described gear I is connected with stepper motor by rotating shaft.
Described swivel nut internal circumferential is furnished with internal thread, and the outside thread of arranging with cylinder rod one end matches.
Described cylinder rod arranges that externally threaded one end stretches out the front end of swivel nut.
Described swivel nut front end is furnished with cross screw.
The described facewidth of gear II is suitable with the stroke of swivel nut.
Described oil cylinder internal placement has the piston vertical with cylinder rod.
beneficial effect
The utility model relates to a kind of tightening oil cylinder for cold header die holder, simple in structure, and oil cylinder can compress die holder in cold header quick die change process, avoids die holder to produce loosening phenomenon.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1-2, mode of execution of the present utility model relates to a kind of tightening oil cylinder for cold header die holder, comprise stepper motor 1, swivel nut 4 and oil cylinder 5, described oil cylinder 5 inner transverse are equipped with the cylinder rod 51 stretching out outside oil cylinder 5 at two ends, T-shaped pressing plate 6 is equipped with in described cylinder rod 51 one end, the other end is socketed with swivel nut 4, described swivel nut 4 is closely affixed with oil cylinder 5 one end, described swivel nut 4 is circumferentially provided with gear II 7, described gear II 7 external gear I 2, described gear I 2 is connected with stepper motor 1 by rotating shaft.
Described swivel nut 4 internal circumferential are furnished with internal thread, and the outside thread 8 of arranging with cylinder rod 51 one end matches.
Described cylinder rod 51 arranges that one end of outside thread 8 stretches out the front end of swivel nut 4.
Described swivel nut 4 front ends are furnished with cross screw 3.
The facewidth of described gear II 7 is suitable with the stroke of swivel nut 4.
Described oil cylinder 5 internal placement have the piston vertical with cylinder rod 51 52.
Embodiment 1
In the time that die holder in die change process is accurately positioned in cold header really fixed position, oil pump is by driving oil cylinder 5 to compress die holder.In the time that oil cylinder 5 compresses die holder, send signal by hydraulic system relay, start stepper motor 1 and work, actuation gear I 2, gear I 2 drives the gear II 7 being engaged with, and gear II 7 turn swivel nuts 4 move forward, and swivel nut 4 reach heads on oil cylinder cover and completed the function of axial tightening oil cylinder.
The facewidth of the gear II 7 on swivel nut 4 is suitable with the stroke of swivel nut 4, and the stroke of swivel nut 4 completes by the default step pitch of stepper motor 1.
Guarantee swivel nut 4 no-idle running of advancing and retreat by the gap-eliminating structure of the threaded screw 3 of surface band.
The tightening of oil cylinder is realized by cold header numerical control device with reset.
