Description

Spray nozzle swing type programme control cleaning phosphating machine

The utility model is as claim 1 described a kind of equipment---the program control cleaning of nozzle oscillation formula (phosphatization) machine that is used for the pre-treatment of sheet metal shell part lacquer.

Existing sheet metal shell part is (as the driver's cabin of various vehicles, vehicle body etc.) lacquer pre-processing device---clean (phosphatization) machine, generally be to adopt be cleaned part arranged around nozzle, it is the external nozzles system, the cleaning or the phosphatization of workpiece outer surface have been realized preferably, and the cleaning of inner surface or phosphatization are to finish by the incident outside some holes of workpiece, such cleaning (phosphatization) mode, make workpiece top board inboard and workpiece dividing plate place intractable arrive, promptly " dead angle " can appear, the cleaning or the phosphatization quality of workpiece have been influenced, directly threatening the paint quality of product, cause the generation of undesired corrosion phenomenon in use of sheet metal shell part, the service life of having reduced product.

In large quantities of mass-produced machine works, for example full-sized car industry factory is to adopt the technology arrangement mode that will coat with lacquer pre-processing device (cleaning machine, phosphatization machine) and painting equipment (paint spray booth and drying chamber etc.) composition mechanization line.Generally speaking, the per pass operation must be provided with an equipment.Yet the outside of generally also only being intended to workpiece is cleaned or the phosphatization operation; For the factory of small batch, small batch automobile industry factory for example, just more difficult cleaning (phosphatization) processing method and the equipment that finds a kind of not only economy but also can guarantee workpiece quality.

The program control cleaning of the utility model nozzle oscillation formula (phosphatization) machine is with make more cleverly, inner surface during the cleaning (phosphatization) that has solved the sheet metal shell part is produced cleans problem, be specially adapted to small batch production, also be applicable to large quantities of a large amount of productions simultaneously.

The swing type jet pipe and the system thereof that are used for cleaning (phosphatization) work piece inner surface are essence of the present invention places.Referring to accompanying drawing 1: the jet pipe that can swing (2) is under the driving of drive unit (1), can tie up respectively around tie point (A), (B) swing, do to go deep into or withdraw from the motion (different conditions as schematically shown in Figure 2 and position) of workpiece, also can reconcile for only in the overall size scope of workpiece (3), swinging or stopping swinging a period of time, to finish the cleaning or the phosphatization at inboard each position of workpiece.The geometry of the jet pipe that can swing (2) is the bent type pipe of making according to the function curve of involute, and at an end that gos deep into workpiece the comb shape nozzle (11) of big jet angle is housed, and the width of cloth that helps improving injection is penetrated face.

According to the punch difference of situation of workpiece, the workpiece of for example asymmetric position that punches is made jet pipe (2) according to function curve, can single or multiplely use, and under the situation that symmetric arrangement punches, can also use in pairs.

Difference according to production lot, clean the project organization of (phosphatization) machine and different: under large quantities of mass-produced situations, this equipment can be included flow production line in, finishes its cleaning or phosphatization (equipment of an operation or cleaning, phosphatization two procedures are share an equipment) under the continuous motion situation of workpiece.In such cases, drive unit itself is to be placed on the dolly that can walk and by another power to drive, do and the motion of the synchronous walking of workpiece, and can after the cleaning of finishing a workpiece or phosphatization operation, faster return, be implemented in operation under the workpiece motion s state.Obviously this kind make also is applicable under the situation of workpiece intermittent movement, i.e. clean during workpiece stop motion or the operation of phosphatization.At this moment, the dolly that drags drive unit both can be traveling--and workpiece produces under the relative motion and cleans or the phosphatization operation; Also can be not traveling--and workpiece does not have the operation under the relative motion.

Under the situation of small lot batch manufacture, drive unit (1) then can be more flexibly together with the make of jet pipe (2) (and system): can lay the walking dolly that drags drive unit (1), can also remove walking dolly.At this moment, it is step that the motion of workpiece then requires, and promptly under the static state of workpiece, finishes its cleaning or phosphatization operation.The groove chamber of splendid attire solution is then by a plurality of settings, and by programme-control, finishes simultaneously on same equipment and cleans or some procedures of phosphatization.

Accompanying drawing 1 also is aided with accompanying drawing 2(drive unit (1), the local amplifier section of nozzle mechanisms such as (2)) be the present invention---an embodiment of the program control cleaning of nozzle oscillation formula (phosphatization) machine.It is made of parts such as drive unit (1), nozzle (2) (above nozzle (11) is housed) back water controlling apparatus (4), backwater switch (5), charge for remittance device (6), water pump (7), check-valves (8), collector pipe (9), outside jet pipe (10), body (12), groove chamber (13) (establishing four branch groove chambers).

This kind make is applicable to the lacquer pre-treatment production of small batch sheet metal shell part.

The drive unit of this equipment (1) is to be directly fixed on the body (promptly not have the walking dolly device), adopts by an electronic loop chain and drives shaped form jet pipe (2)), shaped form jet pipe (2) then is in pairs and symmetric arrangement.

This kind equipment is owing to adopted above-mentioned machinery and corresponding program control system, and same equipment can be finished hot water injection → buck flushing → warm water washing → cold water flush---promptly to whole cleaning processes of workpiece; Or finish all phosphating process processes such as phosphatization liquid → secondary cold wash → ion washing of spraying.

The program control cleaning of jet pipe swing type (phosphatization) machine, owing to adopted and entered that workpiece lumen is cleaned or the phosphatization mode, and jet pipe (2) is made according to function curve, adopted the comb type nozzle of big jet angle again, and under the driving of drive unit (1), do oscillating motion, guaranteed that cleaning surface is big, remedied general cleaning equipment inaccessible abundant cleaning or the phosphatization that top board and dividing plate etc. is located, improved the quality of cleaning (phosphatization) greatly, thereby guaranteed the paint quality of workpiece, prolonged the life-span of workpiece; Owing to adopted the version of jet pipe (2), the stroke that makes its swing is for minimum, thus the overall size of having dwindled equipment.Particularly under the situation that small batch is produced, owing to adopt the tectonic type and the programme-control that cooperate a machine multiple operation of a plurality of solution tanks (being a plurality of grooves chambers) by one one machine, as long as one or two (station or two stations) equipment just can be finished the work that will be finished by a plurality of stations of original multiple devices, reduced number of devices greatly, thereby reduced floor space, save investment, improved operating efficiency.

The program control cleaning of jet pipe swing type (phosphatization) machine promptly can be used as the cleaning of multiple operation, also can be used as the phosphatization of multiple working procedure, the factory that is specially adapted to the small batch scale is used as the cleaning or the phosphatization equipment of sheet metal shell part, also can adopt multiple devices, finish respectively and clean or each procedure of phosphatization, and be equipped with that painting equipment is formed machinery or the automation painted line, and be used for the factory of large quantities of a large amount of scales, can be widely used in all kinds of automobile factorys, tractor plant, the agricultural machinery factory, the factory of mechanical industry factory such as container plant and other similar production tasks.
