Abstract

Disclosed is a railway vehicle floor cloth splicing, repairing and pattern nesting method. The method includes firstly using an infrared level gage to position a part requiring piecing and inlaying on a floor cloth, performing positioning fixation on the positioned part requiring piecing and inlaying, using a manual carving machine to route an area to be spliced, processing a seamless piecing inlay strip or a pattern nesting identification for filling a routing face, finally using a hot melt glue gun to apply a one-component reaction type Hot melt glue to the routing area, the inlay strip and the pattern nesting identification, performing counter weight compression bonding on a bonding surface after glue application, and taking down a counter weight after the hot melt glue is solidified. The method is simple in operation, short in consumed time, and capable of greatly improving actual work efficiency and construction qualities, and achieving seamless splicing of the whole vehicle, splicing and piecing of the floor cloth out of one meter are absent, a process method of performing seamless repairing on the defect parts without destroying large areas of an original floor is achieved in local repairing application, the limit that mark patterns cannot be optionally nested on existing floor cloths is eliminated, and bi-directional promotion of decoration and construction levels of floor cloths of railway vehicles is achieved.

Description

The splicing of a kind of floor of railway vehicle cloth, repairing and pattern nesting method

Technical field

The present invention relates to the splicing of a kind of floor of railway vehicle cloth, repairing and the nested process of pattern.

Background technology

At present, after track bus deck cloth splicing process scheme mainly adopts overlap joint, cutting and two kinds of modes of welding are constructed, but while longitudinally mating formation due to rubber-PVC floor cloth, the technique of splicing with PVC welding rod after V-shaped groove is opened in employing, two width floor cloth stitching portions form a seam clearly, the linearity of seam crossing and flatness are not high, directly affect its surface decoration effect; And the local defect such as in running, trolley coach floor cloth easily causes bulge, tear, when carrying out defect processing process, after many employing large area are raised, again the mode of bonding new floor cloth is processed again, take a lot of work, time-consuming, and the appearance effect after processing is not good; Also have, owing to being subject to the batch production of floor cloth manufacturer and process technology limit, can not on specific floor cloth, design specific pattern according to client's requirement, take to be at present with figuratum pad pasting to be bonded on floor, but very easily come off and breakage, need often to change and repair.

Summary of the invention

The object of this invention is to provide a kind of trolley coach splicing, repairing, pattern nesting method, to realize trolley coach floor cloth, at splicing seam crossing, without obvious floor cloth seam, nothing, splice the phenomenons such as ladder; The local bulge of track bus deck cloth, tear place are repaired; After the floor cloth of having mated formation, enter on original floor cloth needed different colours, variety classes floor cloth pattern are nested, realize floor cloth according to different needs, pattern is designed and constructed, and produced without damaged and obscission by nested pattern floor cloth.

For achieving the above object, the invention provides a kind of floor of railway vehicle cloth splicing, repair and pattern nesting method, it is characterized in that: first utilize infrared ray spirit level to inlay place to the required piece of floor cloth and position, located, need piece to inlay place to carry out position and fix, then with manual engraving machine, band splicing regions is engraved to milling, processing is for filling up seamless piece Inlaid strip or the nested sign of pattern of the milling face of engraving, finally with thermosol gelgun, engraving milling region and Inlaid strip, in the nested sign of pattern, be coated with and play one-component reaction type hot-fusible glue, after playing glue, adhesive surface is carried out to counterweight pressurizing binding, after solidifying, hot melt adhesive takes off balancing weight.

The advantage that the present invention has with respect to prior art and progressive as follows:

(1) constructing operation method is simple, consuming time shorter, has greatly improved real work efficiency and construction quality;

(2) compared with the conventional method realization truly car load seamless spliced, outside one meter without floor cloth splicing seam.

(3) in sectional repair application, realized and need not carry out extensive damage to former floor and can carry out to defect part the process of seamless repairing.

(4) break away from the restriction that existing floor cloth can not any nested sign pattern, realized the two-way lifting of trolley coach floor cloth decoration level and construction level.

The specific embodiment

(1) with infrared ray spirit level, the required splicing of former floor cloth, repairing, the nested place of pattern are positioned, guarantee the horizontal and longitudinal size precision in pending region;

(2) in the determined splicing of infrared ray spirit level, repairing, pattern nested position, with the fixing spacing pattern of 3M glued membrane, spacing pattern can according to splice, repairing, the nested concrete shape of pattern design, as it is longitudinally seamless spliced to carry out car load, spacing pattern can be designed to Lou Xi district is that 20mm is wide, the folding spacing pattern that 3600mm is long; As repaired floor layout portion fault location, can be according to the spacing pattern of the concrete size design of defect, concrete size can design with reference to the design of the longitudinal seamless spliced spacing pattern of car load; As indicated the patterns such as pattern and functional region sign in nested disabled person district on former floor, can design with reference to the design of the longitudinal seamless spliced spacing pattern of car load;

(3) direction limiting by spacing pattern with manual engraving machine or region are carried out horizontal sliding and are engraved milling, and manually engraving machine is engraved milling thickness and be should be floor cloth thickness to be spliced and film thickness sum;

(4) in order not occur after the splicing bar that guarantees to bond, after engraving milling, do not need the phenomenon of step to clear up former floor cloth residual volume with carpenter's flat chisel;

(5) with cleaning agents such as isopropyl alcohol, alcohol, to engraving milling face, carry out cleaning, guarantee to engrave milling face surface neatly, without dirt or oil stain;

(6) at CNC computer machining center according to engraving the size in milling region or the pattern of pattern to be spliced, the nested or composed pattern of splicing that machining needs;

(7) start thermosol gelgun and be coated with and play one-component reaction type hot-fusible glue, before hot melt adhesive surface cure, by required splicing, nested or composed pattern is positioned over and engraves milling place;

(8) with metal weights piece, be covered in splicing nested or composed pattern is surperficial, it exerted pressure, spend 120 minutes after removable metal weights piece carry out surface cleaning processing, after 24 hours, normal use can be recovered in ground.

Claims

1. a floor of railway vehicle cloth splicing, repair and pattern nesting method, it is characterized in that: first utilize infrared ray spirit level to inlay place to the required piece of floor cloth and position, located, need piece to inlay place to carry out position and fix, then with manual engraving machine, band splicing regions is engraved to milling, processing is for filling up seamless piece Inlaid strip or the nested sign of pattern of the milling face of engraving, finally with thermosol gelgun, engraving milling region and Inlaid strip, in the nested sign of pattern, be coated with and play one-component reaction type hot-fusible glue, after playing glue, adhesive surface is carried out to counterweight pressurizing binding, after solidifying, hot melt adhesive takes off balancing weight.
