Abstract
The utility model relates to a flexible curved surface file, which aims to eliminate the defects of the original complicated molded surface maintenance method and has the advantages of high maintenance quality and high maintenance efficiency. The flexible curved surface file comprises a flexible substrate matched with a molded surface to be filed and cut. One surface of the flexible substrate, which is combined with the molded surface to be filed and cut, is provided with a grinding layer. Through using the flexible curved surface file, the flexible curved surface file can be fitted with the corresponding curved surfaces of a drawing die together for maintenance during maintenance, and thereby, the labor time of workers is shortened, the working strength and the requirement of the maintenance on the technique of the workers are reduced, the maintenance quality is greatly improved and the product processing quality is ensured.
Description
Technical field
The utility model relates to the automobile die technical field, and particularly the cold punching die maintenance is filed with flexible curved surface.
Background technology
Existing vehicle exterior cladding element drawing die maintenance technique, be to repair with air operated portable grinder and the oilstone profile after to soldering, because the irregular curved surface of vehicle exterior cladding element mould and the inflexibility of oilstone cause existing maintenance technique can not well make the maintenance position return to original profile state when maintenance.Simultaneously, need during maintenance upper and lower mould repeatedly the matched moulds bedding-in just can reach the repair quality requirement, especially large-scale vehicle exterior cladding element drawing die mould volume is big, heavy, maintenance difficulty, intensity, man-hour are all very high, the craftsmanship are required also higher.
The utility model content
The purpose of this utility model is exactly in order to solve the defective that original complex profile method for maintaining exists, the flexible curved surface file of a kind of high repair quality and maintenance efficiency to be provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of flexible curved surface file, it comprise one with wait to file the flexible substrate that the pin profile matches, described flexible substrate with wait to file the face that the pin profile combines on be provided with grinding layer.
Described matrix is a stainless mild steel plate.
Described grinding layer is a diamond dust coating.
Filing instrument of the present utility model adopts has flexible 302 stainless mild steel plates of certain toughness as matrix, this steel plate thickness is about 1 to 5mm, width about 20 to 30mm, length about 30 to 50cm, by electroplating technology, form diamond dust coating at the mild steel plate electroplating surface.Diamond dust coating composition is the carborundum that carbon and silicon constitute with covalent bond, and hardness is HRC95.According to user demand, adopt different diamond dust granularities, can form following plurality of specifications: 120#, 150#, 180#, 240#, 300#, 400#, 600# etc.Mild steel plate with coating can be crooked, and the toughness before keeping electroplating, and this coating requires to have very strong adhesive force under normal condition and case of bending simultaneously.The integral body that forms with matrix and coating is as instrument, fits with complex profile and carry out filing in crooked back.Because this instrument and profile are fitted during filing, profile after the filing and former profile are consistent, and can more easily disposablely reach maintenance requirement, and can guarantee machining accuracy, have replaced the method for original repeatedly matched moulds bedding-in.
Since can be crooked, can conform to the complex profile of mould well, repair quality and efficient are improved greatly.Diamond dust coating has very strong adhesive force simultaneously, also can satisfy the filing instructions for use under case of bending.
The utility model, compare with original structure, effect is embodied in following three aspects: 1, shortened maintenance time, maintenance efficiency significantly improves.2, maintenance difficulty and labour intensity have been reduced.By the work that original high professional qualification personnel just can finish, having become common pincers worker can finish; Simultaneously, in maintenance process, personnel's matched moulds bedding-in does not repeatedly need repairing yet.3, new maneuver maintenance ratio of precision had also had large increase originally, can disposablely reach maintenance requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1. matrix, 2. grinding layer.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, it comprise one with wait to file the flexible substrate 1 that the pin profile matches, be provided with grinding layer 2 on the flexible substrate 1 with on waiting to file the cambered surface that the pin profile matches.(it can be at the upper face of cambered surface, also can be in the lower surface of cambered surface, preparation gets final product according to actual conditions)
By using flexible curved surface file, can make flexible curved surface file when maintenance and the application of a surface of drawing die correspondence keep in repair together, shortened workman's working time, reduced working strength and maintenance requirement to workman's technology, and improved repair quality greatly, guaranteed product spare crudy.
