Abstract

The utility model relates to a scraper for telescopic guard sheets, which can effectively reduce manufacture cost and simplify manufacture processes. An iron bar is mainly formed by punching and pressing sheet materials, the back edge is folded from lower part to inside into a groove, and the front edge forms a pressing and fastening edge; two flanges are arranged on the lower edge of a scraping strip, and a thin edge is tied on the back edge; the iron bar is fixed at the edge of the telescopic guard sheet which is corresponding to the upper part in a spot welding mode, and the thin edge end of the scraping strip is inserted into the groove of the iron bar; the outer side of the front edge of the scraping strip is just and completely coated by the pressing and fastening edge of the iron bar, the two flanges under the scraping strip are flat attached on the surface of the telescopic guard sheet which is corresponding to the lower part according to the front and back positions, and the desired function of protecting the telescopic guard sheet is achieved.

Description

Scraper for telescopic guard sheet

The utility model provides a kind of removing device, is meant especially a kind ofly can effectively reduce manufacturing cost, simplify manufacturing process, can bring into play the novel extensible protection board removing device of excellent utility function simultaneously again.

Extensible protection board is meant a kind of device that is fixed in metal cutting machinery sliding platform; it is to make the different lid shape plate of size by several iron plates; be socketed to form one by one according to size; make it have flexible function; leading edge at each lid shape is all established again with removing device; prevent iron filings or entering of other foreign material and the scratch damage in order to the protection plate body, thereby keep production capacity and service life of whole parts is provided.

Yet, as everyone knows, the removing device of generally commonly using is made up of an iron bar and a scraping article, wherein, this iron bar all is to adopt that long iron prop rolling more than ten secondaries prolonged etc. procedure of processing can obtain required dimensional accuracy and shape, but it is to construct with the normal temperature state in the process of processing, and carrying out one by one along with procedure of processing, the sclerosis (accumulation one by one of internal stress) that becomes of also will healing one by one of its material is so when next procedure of processing is carried out, just need impose bigger external force; But, when excessively big external force imposes on the material that work hardening takes place, the ruined misgivings of material will be arranged, so, just need suspend procedure of processing backward this moment, make it softening, continue procedure backward again to than after the hardness that is fit to processing and earlier this material is carried out annealing in process.

Therefore, above-mentioned material is handled, is reprocessed via initial processing, sclerosis, annealing softening and to processes such as finished products, will expend more man-hour and cost, so for operation on a large amount of production lines, really belong to a very serious drawback.

Secondly, above-mentioned material is through repetitiousness and processing repeatedly midway, its machining accuracy must be noted and control to operator constantly, in case even its preliminary error causes the bad of finished product to can't bear to use, otherwise just can produce too much waste product and cause meaningless burden, so be again another serious puzzlement of known method for making.

The purpose of this utility model is, the designer is because many disadvantages of being hidden in the hiding in the above-mentioned known extensible protection board processing procedure, with its actual for many years design and manufacturing experience of being engaged in this series products, the exploitation of actively concentrating on studies, phase can effectively be simplified the processing procedure of iron bar, it is not only still had outside the original effect, more reduce cost to be suitable for a large amount of productions.

Another purpose of the present utility model is the compound mode of iron bar and scraping article for a change, so that user's assembling and replacing.

The purpose of this utility model is realized by following technical scheme.

A kind of extensible protection board removing device, its removing device comprise an iron bar and a scraping article, and wherein said iron bar is with drawing, and bend inwards into a groove under the cause after it, and leading edge then forms the clinching edge; In addition the lower edge in scraping article is provided with two flanges, makes again that its trailing edge is a thin edge, in order to making up with iron bar.

The utility model compared with prior art advantage and good effect is fairly obvious.Owing to adopt the design of above-mentioned member; after iron bar is fixed in the extensible protection board edge of relative top in the spot welding mode; make scraping article insert in the groove of iron bar again with its thin acies; the clinching edge of iron bar just coats the leading edge outside of scraping article fully; and two flanges of scraping article below are just smooth on the extensible protection board surface of relative below according to forward and backward position, reach the function of expection protection extensible protection board.Can effectively reduce manufacturing cost, simplify manufacturing process, reach the effect of expection protection extensible protection board.

Further understand technological means of the present utility model and architectural feature in depth for making, conjunction with figs. is specified in the back now:

Fig. 1: be exploded perspective view of the present utility model.

Fig. 2: be structural profile schematic diagram of the present utility model.

As shown in Figure 1 and Figure 2, its removing device comprises that an iron bar 10 and a scraping article 20 constitute, so it mainly is that iron bar 10 is made with sheet material (not being shown in figure) punching press, and makes it bend inwards into a groove 12 under cause afterwards, and leading edge then forms clinching edge 14; The lower edge of its scraping article 20 is provided with two flanges 22, makes that its trailing edge is a thin edge 24 again; Utilize the design of above-mentioned member; when iron bar 10 is fixed in extensible protection board 30 edges of relative top in the spot welding mode after; make scraping article 20 insert in the groove 12 of iron bar 10 again with its thin edge 24 ends; at this moment; the clinching edge 14 of iron bar 10 just coats the edge outside before the scraping article 20 fully; and two flanges 22 of scraping article 20 belows are just smooth on extensible protection board 32 surfaces of relative below according to forward and backward position, reach the effect of expection protection

extensible protection board

30,32.

Taking a broad view of above institute says, the utility model uses with simple technology, and the utility model is conformed with more simplify, certain actively and positively effect, in the known product that diminishes fully at one stroke virtually on the processing procedure and the serious careless mistake in the design, its excellent and perfectly structural design and method for making, forgiving and conform with patent requirement, is one to have the new design of novelty practicality in fact.

Claims

1, a kind of extensible protection board removing device, its removing device comprises an iron bar and a scraping article, it is characterized in that:

Described iron bar is with drawing, and bends inwards into a groove under the cause after it, and leading edge then forms the clinching edge; In addition the lower edge in scraping article is provided with two flanges, makes again that its trailing edge is a thin edge, in order to making up with iron bar.
