Background
In order to ensure that the upper and lower split parts of the die parting surface of the die firmly buckle the pipe along the die assembly direction in the high-pressure forming process in the fluid, the trend of opening the die and tearing and breaking the pipe up and down by internal high-pressure forming force is counteracted, and the sufficiently high die locking force is a prerequisite condition for the high-pressure forming in the fluid. The mold locking force is provided by the main oil cylinder. Because the tonnage of the internal high-pressure fluid forming is very large, the mold locking force required by the internal high-pressure fluid forming is very high (for internal high-pressure forming equipment or a mold, if the mold clamping force is insufficient, the internal high pressure explodes the pipe, the pipe props the mold, and accidents are easy to happen), and a driving oil cylinder with very large driving force is correspondingly needed, so the inner diameter area of the oil cylinder needs to be large enough. And because the mold is taken out when the mold is opened, the mold opening stroke must be large enough, and a driving oil cylinder with large stroke and large inner diameter is needed to drive the mold locking. Therefore, when the mold is opened and closed by a long stroke, the flow rate and the total oil amount flowing through the main oil cylinder are both quite large, the consumed time is prolonged, the consumed energy is increased, and the energy and the time are wasted.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 8, the internal high pressure fluid forming apparatus of the present invention includes a lower module 10, an upper module 12, and a hydraulic oil driven mold locking mechanism. Preferably, the internal high pressure fluid forming apparatus further comprises a hydraulic oil control system. Wherein:
the hydraulic oil driven clamping mechanism comprises a small inner diameter pushing oil cylinder 21, a large inner diameter main oil cylinder 22, at least two locking modules 23 and at least two locking module pushing oil cylinders 24 corresponding to the small inner diameter pushing oil cylinder, wherein the small inner diameter pushing oil cylinder 21, the large inner diameter main oil cylinder 22, the locking modules 23 and the locking modules are fixed above the upper module 12 through a fixing part; the height of the locking module 23 is smaller than the pushing distance of the small inner diameter pushing cylinder 21, when the upper die is assembled on the lower die set, the two locking modules push the cylinders 24 to push the corresponding locking modules 23 to move in opposite directions, so that the upper top of the locking module 23 is abutted against the bottom surface of the fixed part, and the lower abutting part is abutted against the top surface of the main cylinder body, thereby sealing the upper die set on the lower die set. The small inner diameter pushing cylinder 21, the large inner diameter main cylinder 22 and the locking module pushing cylinder 24 are all connected with a hydraulic oil source through oil way pipelines.
In this embodiment, the inner diameter of the small inner diameter pushing cylinder 21 is smaller than the inner diameter of the large inner diameter master cylinder 22, the small inner diameter determines the stroke according to the opening degree of the different inner high-pressure fluid forming devices, and generally, in order to take out a formed product conveniently, the opening degree of the mold opening is large, so that the stroke of the small inner diameter pushing cylinder 21 is long.
In this embodiment, the fixing portion is an upper cross beam, the cylinder body of the small inner diameter pushing cylinder 21 is fixed on the upper cross beam, and the piston rod passes through the upper cross beam downward and is then rigidly connected to the top surface of the main cylinder body of the large inner diameter main cylinder 22.
In this embodiment, the two locking module pushing cylinders 24 are horizontal pushing cylinders, and when the upper mold is assembled on the lower mold set, the two locking module pushing cylinders 24 push the corresponding locking modules 23 to move in opposite directions, so that the upper tops of the locking modules 23 are abutted against the upper cross beam, and the lower abutting portions are abutted against the top surface of the main cylinder body.
The hydraulic oil control system is used for driving the small inner diameter pushing oil cylinder 21 to rapidly push the large inner diameter main oil cylinder 22 downwards to move downwards so as to enable an upper die set 12 connected with the large inner diameter main oil cylinder to be combined on the lower die set 10, and is also used for driving the two locking module pushing oil cylinders 24 to push the corresponding locking modules 23 to move towards opposite directions after the upper die set 12 is combined on the lower die set 10, so that the two locking modules 23 are both positioned above the main cylinder body, and is also used for controlling oil inlet of an upper cavity and oil outlet of a lower cavity of the main cylinder body so as to push a piston rod of the large inner diameter main oil cylinder 22 to move downwards when the die is locked, and enabling the main cylinder body to move upwards so as to be propped against the bottom surface of the locking modules 23 to complete die locking under the condition that the upper die set 12 is. The hydraulic oil control system is also used for controlling the lower cavity of the main cylinder body to feed oil and the upper cavity to discharge oil when the mold is opened, and enabling the piston rod of the large-inner-diameter main oil cylinder 22 to retract inwards under the condition that the upper module 12 abuts against the lower module 10, so that the main cylinder body moves downwards to reserve a space for resetting the locking module 23; the hydraulic oil control system is also used for controlling the two locking modules to push the piston rods of the oil cylinders 24 to return so as to reset the two locking modules 23; and the hydraulic oil control system is also used for controlling the lower cavity 211 of the small inner diameter pushing oil cylinder 21 to feed oil and the upper cavity 212 to discharge oil when or after the two locking modules 23 are reset, so that the piston rod of the small inner diameter pushing oil cylinder 21 is retracted inwards to reset, and the main cylinder body and the upper module are driven to move upwards to reset to complete the die opening. When the mold is locked, firstly, the hydraulic oil control system controls oil to enter the upper cavity 212 of the small inner diameter pushing oil cylinder 21, and at the moment, the lower cavity 211 of the small inner diameter pushing oil cylinder discharges oil, so that the piston rod of the small inner diameter pushing oil cylinder 21 moves downwards, the large inner diameter main oil cylinder 22 moves downwards, and the upper module 12 is driven to move towards the lower module 10 so as to be combined with the lower module 10. Then, after the upper module 12 is assembled on the lower module 10, the hydraulic oil control system controls the two lock module pushing cylinders 24 to push the corresponding lock module 23 inwards, so that the lock module is located above the main cylinder body, and since the piston rod of the small inner diameter pushing cylinder reaches the descending position and the height of the lock module 23 is smaller than the descending stroke of the piston rod of the pushing cylinder, the lock module 23 can be smoothly pushed above the main cylinder body. Then, the hydraulic oil control system controls oil to enter the upper cavity 222 of the large-inner-diameter main oil cylinder 22, at this time, the lower cavity 221 of the large-inner-diameter main oil cylinder 22 discharges oil, in this state, because the upper module 12 is abutted against the lower module 10 under the action of the small-inner-diameter push oil cylinder, in this case, the piston rod of the large-inner-diameter main oil cylinder 22 is moved outwards, only the main oil cylinder can move upwards, and because the stroke of the small-inner-diameter push oil cylinder is greater than the height of the lock module 23, in the state that the main oil cylinder 22 moves upwards and is abutted against the bottom surface of the lock module 23, the piston rod of the small-inner-diameter push oil cylinder retracts inwards, so that the top surface of the lock module 23 is abutted against the upper cross beam, and the bottom surface is abutted against the main cylinder body. Thus, mode locking is completed.
After the mold locking is completed, the internal high-pressure fluid forming equipment can work to form a product. Referring to fig. 5 in detail, the forming material side cylinder 101 of the internal high-pressure fluid forming apparatus pushes the material supplement pipe to inject the material to the cavity of the mold, thereby forming the product.
It can be understood that the above-mentioned small inner diameter and large inner diameter are compared with each other, and because the mold has a large volume and a heavy weight, and needs a large force to lock the mold when the mold is to be locked, the master cylinder connected to the upper module 12 must use the master cylinder with a large inner diameter corresponding to the mold to lock the mold. And the pushing oil cylinder for driving the main oil cylinder to move to the mold position does not need a large amount of oil because the weight and the volume of the main oil cylinder are not large, so that the inner diameter of the pushing oil cylinder can be smaller than that of the main oil cylinder. Therefore, the small and large in this context are used to compare the inner diameters of the master cylinder and the push cylinder. The inner diameter of the small inner diameter pushing oil cylinder is mainly determined according to the weight of the large inner diameter main oil cylinder, the required speed, the required volume, the oil consumption and other factors, and the small inner diameter pushing oil cylinders with different inner diameters can be selected according to requirements in different embodiments.
The utility model discloses interior high-pressure fluid former and series connection hydro-cylinder clamping mechanism thereof, its simple structure is but design benefit. The small inner diameter pushing cylinder (small inner diameter long stroke oil cylinder) is connected with the main oil cylinder (large inner diameter short stroke mold locking oil cylinder) in series up and down, the extending end of a piston rod of the small inner diameter pushing cylinder is rigidly connected with the main cylinder body, the working cavity of the small inner diameter pushing cylinder is filled with oil to drive the piston rod to be matched with the whole main cylinder in a downward mode, and the low-flow and quick operation process is realized; the main oil cylinder moves to lock the mold in a small stroke, so that the time consumption is short, the energy consumption is low, and the resources are saved.
The utility model also discloses a mode locking method of interior high-pressure fluid former, including following step:
s101, controlling the upper cavity of the small inner diameter pushing oil cylinder to feed oil and the lower cavity of the small inner diameter pushing oil cylinder to discharge oil by a hydraulic oil control system, so that a large inner diameter main oil cylinder connected with the small inner diameter pushing oil cylinder is pushed to move downwards, and an upper die set 12 is combined on a lower die set 10;
s102, the hydraulic oil control system controls the two locking modules to push the oil cylinders 24 to push the corresponding locking modules to move towards opposite directions, so that the two locking modules are both positioned above the main cylinder body;
s103, controlling the upper cavity of the main cylinder body to feed oil and the lower cavity to discharge oil to push the piston rod of the large-inner-diameter main oil cylinder to move downwards by the hydraulic oil control system, and enabling the main cylinder body to move upwards to prop against the bottom surface of the locking module to complete mode locking under the condition that the upper module 12 abuts against the lower module 10.
The utility model also discloses a die sinking method of interior high-pressure fluid former includes following step:
s201, the hydraulic oil control system controls the lower cavity of the main cylinder body to feed oil and the upper cavity to discharge oil, and the piston rod of the large-inner-diameter main oil cylinder retracts inwards under the condition that the upper module 12 abuts against the lower module 10, so that the main cylinder body moves downwards to reserve a space for resetting the locking module;
s202, the hydraulic oil control system controls the two locking modules to push piston rods of the oil cylinders 24 to return so that the two locking modules are reset;
and S203, the hydraulic oil control system controls the lower cavity of the small inner diameter pushing oil cylinder to feed oil and the upper cavity to discharge oil so that a piston rod of the small inner diameter pushing oil cylinder retracts inwards to reset, and therefore the main cylinder body and the small die are driven to move upwards to reset to complete die opening.
The above is only the embodiment of the present invention, not the limitation of the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
