Abstract
The utility model relates to a duplex station cast pipe hydrostatic testing machine, which comprise a machine base, a socket retaining wall, a faucet retaining wall, a pull rod, socket end plugs, faucet end plugs, main hydro cylinders, lifting devices, a roller way, a pressing device, a shield, a hydraulic system and a water injection pressure testing system. The lower ends of the socket retaining wall and the faucet retaining wall are fixed on both ends of the machine base, and the upper ends are provided with the pull rod for reinforcing. The socket end plugs are fixed on the socket retaining wall through the main hydro cylinders. The faucet retaining wall which is arranged on the same horizontal line as the socket retaining wall is provided with the faucet end plugs. The main hydro cylinders are connected with the hydraulic system. The socket end plugs and the faucet end plugs are connected with the water injection pressure testing system. The machine base arranged between the socket end plugs and the faucet end plugs is fixed with the lifting devices, and the roller way is arranged at the front and the back parts of the lifting devices. Two sets of the socket end plugs, the faucet end plugs, the main hydro cylinders and the lifting devices are arranged side by side, so two cast pipes can be tested at one time. The utility model has the advantages of small area occupation, little investment, little worker requirement and low production cost.
Description
(1), technical field
The utility model relates to a kind of magnesium iron cast tube double water test unit.
(2), background technology
For quality and the mechanical property that guarantees the magnesium iron cast tube, ISO2531-98 and GB13295-91 regulation magnesium iron cast tube must carry out the hydraulic testing by root pressure in accordance with regulations.The water pressure engine of relevant manufacturer use respectively has its characteristic both at home and abroad, but the structure of equipment is identical with principle of work substantially, all is single station hydrostatic testing machine, promptly once only tests a cast tube.It can only satisfy the production demand of the water-cooled metal mould hydro-extractor of a same specification, and several hydrostatic testing machines of several desk centrifuges outfit are just arranged like this, and not only the place area occupied is big, and investment is big, and the personnel that need are many, the production cost height.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of double cast tube hydrostatic testing machine, and its floor area is little, invests for a short time, and the personnel that need are few, and production cost is low.
The technical scheme in the invention for solving the technical problem is: it comprises support, the socket barricade, the bellmouth barricade, pull bar, the socket end is stifled, female end is stifled, master cylinder, jacking gear, roller-way, screwdown gear, protective cover, hydraulic system and water filling pressure testing system, socket barricade and bellmouth barricade lower end are fixed on the two ends of support, the upper end has pull bar to reinforce, the socket end is stifled to be fixed on the socket barricade by master cylinder, fixedly female end is stifled on same horizontal bellmouth barricade with it, master cylinder links to each other with hydraulic system, the socket end is stifled to link to each other with the water filling pressure testing system with female end is stifled, the fixing jacking gear on the stifled and female end support between stifled at the socket end, there is roller-way the front and back of jacking gear, upper end fixedly screwdown gear and protective cover between socket barricade and bellmouth barricade, described socket end is stifled, female end is stifled, master cylinder, jacking gear two covers that are arranged side by side promptly can two cast tubes of single test.
Owing to adopt and once can test two cast tubes, the most twice of boosting productivity, floor area is little, invest for a short time, and the personnel of needs are few, and production cost is low, remarkable in economical benefits.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model vertical view;
Fig. 3 is the utility model left view.
(5), embodiment
The utility model comprises that support 2, socket barricade 3, bellmouth barricade 11, pull bar 6, socket end are stifled 5, female end is stifled 10, master cylinder 1, jacking gear 9, roller-way 12, screwdown gear 13, protective cover 7, hydraulic system and water filling pressure testing system, as shown in drawings.Socket barricade 3 and bellmouth barricade 11 lower ends are fixed on the two ends of support 2, the upper end has pull bar 6 to reinforce, and socket end stifled 5 is fixed on the socket barricade 3 by master cylinder 1, in order to increase the rigidity of socket end stifled 5, the lower end of socket end stifled 5 is running roller fixedly, and running roller is sitting on the support 2.With the stifled 5 same horizontal bellmouth barricades 11 of socket end on fixing female end stifled 10.Described master cylinder 1 links to each other with hydraulic system.Described socket end stifled 5 and female end stifled 10 link to each other with the water filling pressure testing system.Fixing jacking gear 9 on the support 1 between socket end stifled 5 and the female end stifled 10, there is roller-way 12 front and back of jacking gear 9.Upper end fixedly screwdown gear 13 and protective cover 7 between socket barricade 3 and bellmouth barricade 11.Described socket end is stifled 5, female end is stifled 10, master cylinder 1, jacking gear 9 are arranged side by side two covers, staggers up and down, with the width of less complete machine.
The principle of work of water pressure engine is as follows: cast tube 8 is sent into the water pressure engine working position by roller-way 12, and jacking gear 9 rises to working depth with it, and master cylinder 1 is pressed on cast tube 8 on socket end stifled 5 and the female end stifled 10 by socket end stifled 5.Start the water filling in cast tube 8 of water filling pressure testing system then, fills with water also will be pressurizeed after the air emptying in the cast tube 8, and hydraulic pressure is risen to the pressure of regulation, can judge whether cast tube 8 is qualified after pressurize a period of time (being generally 15 seconds).Discharge water, master cylinder 1 is return, and cast tube 8 descends and delivers to next station, thereby finishes the working cycle of a hydraulic testing.
