Abstract
A kind of method and apparatus of making the railway car ceiling.Ceiling is made of interior outer jacket and middle synthetic resin foam layer.By the present invention, sheath moulding in moulding and veneering equipment, the top by foaming machine is transported to the foaming machine place then.Present device is made of the upper and lower part, and its top is provided with a vacuum tank 2, and it is suspended on the portal frame 5 of crossing over bottom 1 by lift cylinder 3, and can move up and down.Have aspirating hole on the tool empty van downside, when the centrifugal exhaust fan 9 that links to each other with vacuum tank turned round, just the sheath with forming was adsorbed on the vacuum tank, prevents that thus the sheath of rigidity difference is out of shape in transit.
Description
The present invention relates to a kind of manufacturing large tracts of land arch composite component, especially make the method for the vault of railway carriage of composite construction, this member have inside and outside sheath and insert this two-layer between and polyurethane rigid foam that they are tied.In addition, the invention still further relates to a kind of equipment of implementing this method.
Known by DD-PS 221974, in order to make the arch combined type member of railway car ceiling, prefabricated outer jacket and its skeleton are inserted the foaming machine bottom together, sheath then clamps bar by means of the what is called along the ceiling longitudinal extension, be fixed on its upper side of opening that conforms to profile in the ceiling, closed then this equipment, and insert the synthetic resin foam by existing method.The major defect of this process is, prefabricated sheath in transit can gross distortion, and this is because sheath mainly is to be used for preventing that the synthetic resin foam is stressed and to make moist, thus it be designed to be thin and area big, the shape instability; But also it must be fixed on the top of foaming machine, this fixingly also can only under the ten minutes difficult condition, carry out.
The objective of the invention is to simplify this method, and this process also can be suitable for as thin as a wafer member sheath.
Task of the present invention also comprises and proposes a kind of suitable prefabricated member sheath as thin as a wafer and this sheath of transportation, and with its correct position be fixed on method on the foaming machine.In addition, the present invention also proposes a kind of equipment of implementing the method.
By this method, each unit of sheath, moulding in a moulding that is designed to the spill that conforms to profile in the member and bonding device, and compose complete sheath by means of a kind of suitable binding agent.With the foaming machine top that its underpart separates, move on to moulding and bonding device top, and with its protruding following profile drop to prefabricated sheath above.Utilize a getter device that is contained in foaming machine top, the sheath position is adsorbed on the top of foaming machine exactly, subsequently, this equipment is utilized to again as means of transport, move on to and the cooperative position of foaming machine, and closed this equipment.At this moment, make the member foaming with existing mode.Before closed foaming machine, earlier outer jacket is inserted in the bottom of foaming machine by existing mode.
This equipment comprises an equipment bottom, and it designs routinely, is used for laying prefabricated outer jacket.By the present invention, its upper side is suspended on the hoisting apparatus, and can it be mentioned from the equipment bottom by this hoisting apparatus.Hoisting apparatus is contained on the portal frame of crossing over this equipment, portal frame can be longitudinally or the side move to above the sheath fabricated device on this equipment front or next door.The stable vacuum tank of upper design forming shape of equipment has aspirating hole, and centrifugal exhaust fan is housed on vacuum tank, so that form low pressure in vacuum tank on vacuum tank and downside that profile in the vehicle car ceiling conforms to.The arrangement mode of aspirating hole is: be designed to its upper side downside marginal zone at vacuum tank, have the less little aspirating hole of many distances; And distance is uniform-distribution with big aspirating hole significantly on all the other areas.
The working method of this equipment is as follows.Its upper side of mentioning from the equipment bottom, with portal frame longitudinally or side direction move on to the top of the sheath fabricated device that is positioned at equipment front or next door.In this device, putting the sheath as preformed and the member that is formed by connecting of surface smoothing.By hoisting apparatus, its upper side that is designed to vacuum tank is dropped on the sheath, and connect centrifugal exhaust fan.
Low pressure by being caused by centrifugal exhaust fan is adsorbed on its upper side with sheath.Mention sheath in the fabricated device by handling hoisting apparatus.And then portal frame is moved on to the operating position that is positioned at top, equipment bottom, thereby just prefabricated sheath is transported in the equipment.Descending device top, and make it with the mutually positioning locking in equipment bottom after, as existing method, the compartment ceiling just can couple together by the expanded foamed of polyurethane rigid foam.
Accompanying drawing has been represented embodiment, wherein:
The schematic diagram that Fig. 1 its upper side hangs on portal frame,
The upward view of Fig. 2 its upper side schematically illustrates the exhaust situation of aspirating hole,
Fig. 3 portal frame comprises the schematic top plan view of its upper side and sheath fabricated device structure.
An equipment bottom 1 of designing by existing mode is arranged in this equipment, and it is used for laying the outer jacket of compartment ceiling.Its its upper side comprises the vacuum tank 2 of a dimensionally stable, and it is suspended on the portal frame 5 by lift cylinder 3, and portal frame can longitudinally move to the top of fabricated device 4 always.The shape of vacuum tank 2 lower surfaces conforms to the interior profile of compartment ceiling, and known locking device 6 is housed on the vacuum tank, so that be located by connecting with equipment bottom 1.A plurality of centrifugal exhaust fans 9 are housed on vacuum tank, and the end of bleeding of air exhauster links to each other with the inner chamber of vacuum tank 2.On the lower surface of vacuum tank 2, have a plurality of little aspirating holes 7, on remaining surface, the bigger aspirating hole of some diameters 8 with apart bigger range distribution around its surrounding zone.As known, outer jacket is ready made, and it has required reinforcing section, and is placed into the bottom of foaming machine.By the present invention, sheath is in moulding that separates separately and bonding device, is composed the sheath of true-to-shape compartment ceiling size by means of suitable adhesive by unit one by one.Moulding and bonding device are placed in the front or the next door of foaming machine.
In order to lay the sheath of compartment ceiling, portal frame 5 is moved to the top of moulding and bonding device 4, and drops to above the prefabricated sheath by its upper side that lift cylinder 3 will be designed to vacuum tank 2.At this moment, connect centrifugal exhaust fan 9, in vacuum tank 2, produce a low pressure, so sheath is adsorbed and is close on the vacuum tank 2.Under the situation of connecting centrifugal exhaust fan 9, utilize lift cylinder 3, vacuum tank 2 and the compartment ceiling sheath that is adsorbed on above it are upwards mentioned, and and then move on to the top of equipment bottom 1 together with portal frame 5.Like this, its upper side that is designed to vacuum tank 2 is utilized to as means of transport.At the terminal location that is positioned at the portal frame 5 above the equipment bottom 1, by lift cylinder 3 with its upper side transfer to can with the tram of equipment bottom 1 mutual positioning and locking, then insert the polyurethane rigid foam by existing mode.
This design by this embodiment of the present invention and its upper side, it can be used as the means of transport of the compartment ceiling sheath of prefabricated rigidity difference simultaneously, and saved other fixture, overcome existing existing difficulty when sheath is fixed on its upper side fully.
