Abstract
The patent relates to a water injection end pressure testing device of a hydraulic press. The water injection end pressure testing device comprises a stand and a support cart, and is characterized in that a pair of support hydraulic cylinders are vertically and oppositely arranged in the front of the stand; each support hydraulic cylinder is connected with a support block; the support blocks are slidingly arranged on the stand through chutes; a pair of mold base hydraulic cylinders are arranged on two side faces of the stand in parallel; the mold base hydraulic cylinders are connected to water injection end mold bases; the water injection end mold bases are arranged on the support cart; each of the water injection end mold bases is provided with a flange on one surface facing to the stand, and is connected with a plunger through a flange. The pressure testing device has an advantage of accurately positioning.
Description
Technical field
This patent belongs to hydraulic pressure test machine technology field, particularly relates to a kind of water pressure engine water filling end pressure testing device.
Background technology
At present, steel pipe hydraulic pressure test facility have a water filling end pressure testing device and an exhaust end pressure testing device, because exhaust end pressure testing device is comparatively complicated, so the centering of steel pipe be take exhaust end pressure testing device as benchmark.The all parts of water filling end pressure testing device of the prior art is fixedly connected on base, if the steel pipe center of being determined by exhaust end pressure testing device also not exclusively overlaps with water filling end pressure testing device, can cause so bracing or strutting arrangement can not well support steel pipe, water filling terminal mould seat can not well be realized the combination with steel pipe.
Summary of the invention
This patent provides a kind of water pressure engine water filling end pressure testing device for solving the technical matters existing in known technology, and this pressure testing device can accurately be located.
A kind of water pressure engine water filling end pressure testing device, comprise frame and supporting carriage, it is characterized in that: on before frame, a pair of supporting cylinder is vertically installed in opposite directions, each supporting cylinder is all connected with back-up block, back-up block is slidably mounted in frame by chute, frame two sides are also parallel is provided with a pair of mold base hydraulic cylinder, mold base hydraulic cylinder is connected with water filling terminal mould seat, water filling terminal mould seat is arranged on supporting carriage, water filling terminal mould seat is provided with flange in the one side towards frame, and is connected with plunger by flange.
This patent can also be by the following technical solutions:
Preferably, before frame, be also provided with adjusting gear, adjusting gear holds out against stayed mast by jackscrew.
Advantage and good effect that this patent has are:
Because this patent adopts technique scheme, by back-up block and the formed quadrilateral structure of chute, guaranteed back-up block Off-Radial position when mobile, thereby avoided compressing the situation of steel pipe.And by the setting of adjusting gear, make this device can regulate the relative position with stayed mast, and and then the relative position of adjusting and exhaust end pressure testing device, thus guaranteed and the centering of exhaust end pressure testing device, improved the accuracy of location.
Accompanying drawing explanation
Fig. 1 is the structural representation of this patent;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the B-B cut-open view of Fig. 2.
In figure: 1, frame; 2, supporting cylinder; 3, flange; 4, water filling terminal mould seat; 5, mold base hydraulic cylinder; 6, supporting carriage; 7, back-up block; 8, chute; 9, adjusting gear; 10, stayed mast; 11, plunger.
Embodiment
For further understanding utility model content, the Characteristic of this patent, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1～3,
A water pressure engine water filling end pressure testing device, comprises frame 1 and supporting carriage 6, frame above on a pair of supporting cylinder 2 is vertically installed in opposite directions, each supporting cylinder is all connected with back-up block 7, back-up block is slidably mounted in frame by chute 8.Supporting cylinder drives upper and lower back-up block to move in chute, meets the compression requirement of different steel pipe calibers.The four limit structures that upper and lower back-up block, chute and frame form can be avoided back-up block Off-Radial position when mobile, thereby avoid compressing the situation of steel pipe.Frame two sides are also parallel is provided with a pair of mold base hydraulic cylinder 5, mold base hydraulic cylinder is connected with water filling terminal mould seat 4, water filling terminal mould seat is arranged on supporting carriage 6, and water filling terminal mould seat is provided with flange 3 in the one side towards frame, and is connected with plunger 11 by flange.
Before frame, be also provided with adjusting gear 9, adjusting gear holds out against stayed mast 10 by jackscrew.
The operating principle of this patent is:
Supporting cylinder 2 drives upper and lower two back-up blocks 7 to move in chute, meets the compression requirement of different steel pipe calibers.Upper and lower two back-up blocks, chute 8 can be avoided back-up block Off-Radial position when mobile with the four limit structures that frame forms, thereby avoid compressing the situation of steel pipe.Mold base hydraulic pressure 5 cylinders drive water filling terminal mould seat 4 and supporting carriage 6 to move by sliding and can supporting stressed plunger 11, and fixed journey system before and after guaranteeing, meets determining of steel pipe material loading pipe end pressure testing initial position.On plunger, have dust seal and lubricated, can make plunger slide at frame internal freedom, when water filling end pressure testing device is started working, mold base hydraulic cylinder drives plunger backhaul 1mm backward, effectively guarantees self-locking, increases stability.
Although by reference to the accompanying drawings the preferred embodiment of this patent is described above; but this patent is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of this patent; not departing from the scope situation that this patent aim and claim protect, can also make a lot of forms, within these all belong to the protection domain of this patent.
