Description
Technical Field
The invention relates to the field of machinery, in particular to a molded surface repairing method of a punching die, and specifically relates to a repairing method of a punching die of a stator blade of an air compressor.
Background
Fig. 1 is a schematic structural diagram of a compressor stator blade, and referring to fig. 1, the compressor stator blade 1 has a thicker head end 11 with an arc shape, a thinner tail end 12, a root portion 13 and a tip end 14, the thinnest portion of the tail end 12 is only 0.15mm, and the root portion 13 is provided with two notches 131. The stator blade 1 of the air compressor is processed and manufactured in a punching mode. Fig. 2 is a schematic structural diagram of a conventional punching mold for manufacturing the compressor stator blade shown in fig. 1, and as shown in fig. 2, the punching mold 2 includes a bottom plate 21, a female mold 22 disposed on the bottom plate 21, and a male mold 23 corresponding to the female mold 22 and capable of reciprocating up and down, the female mold 22 is provided with a punching cavity 221, a top block 24 capable of sliding up and down is disposed in the punching cavity 221, when punching is performed, the male mold 23 extrudes a material into the punching cavity 221, the material is cut around the punching cavity 221, the male mold 23 and the top block 24 further perform extrusion forming on the cut material, and after the punching forming is completed, the top block 24 can eject a processed finished product out of the punching cavity 221.
Because the profile of the compressor stator blade 1 is complex and uneven in thickness, when the profile of the top block 24 has deviation, the material cannot be well supported in the punching process, namely, the material cannot be well attached, so that when punching is easily caused, the edge of the tail end 12 of the product is curled due to uneven stress of the material.
When the edge of the tail end 12 is curled, the conventional solution is to color the compressor stator blade 1 which is already finished, and then repeat the punching process in the punching die 2 to color the top block 24, so that the coloring point on the top block 24 can be polished until the coloring is uniform. The edge curling condition can be relieved to a certain extent through the repair of the method, but the stress state is complex during punching due to certain distortion of the upper and lower molded surfaces of the compressor stator blade 1, and the top block 24 cannot well support materials after the repair, so that the problem of edge curling of the thin edge cannot be thoroughly solved through the traditional coloring and grinding.

Detailed Description
For a more clear understanding of the technical features, objects and effects of the invention, specific embodiments thereof will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
FIG. 1 is a schematic view of a compressor stator blade configuration; FIG. 3 is a schematic illustration of a method of repairing a compressor stator blade blanking die in accordance with an embodiment of the present invention; fig. 4 is a schematic top view of the top block of fig. 3. Referring to fig. 1, 3-4, the invention provides a method for repairing a die-cutting die of a compressor stator blade, which is used for repairing the profile of a top block 24 of a die-cutting die 2, wherein the compressor stator blade 1 is provided with a thicker head end 11 with an arc shape, a thinner tail end 12, a blade root 13 provided with two notches 131 and a blade tip 14, the thinnest part of the tail end 12 is only 0.15mm, and the method comprises the following steps,
step A, coloring the manufactured qualified compressor stator blade 1, then placing the compressor stator blade in the punching die 2 to repeat the punching process, then polishing the coloring points on the top block 24, and repeating the step until the top block 24 is uniformly colored;
as described in the background art, when the profile of the top block 24 of the punching die 2 is changed due to wear or impact damage during use, the top block 24 may not support the material well, i.e. may not fit the material well, so that the edge of the tail end 12 of the product may be curled due to uneven stress when punching is performed.
In this case, it is first necessary to polish the painted points of the top block 24 (i.e., the protrusions of the top block 24) by painting according to the conventional method described in the background art until the top block 24 is painted uniformly (i.e., it is indicated that the profile of the top block 24 can be well fitted to the finished compressor stator blade 1).
And B, dividing the profile of the top block 24 into a head end region 241, an intermediate region 242, a tail end region 243, a root end 244 and a tip end 245 corresponding to the compressor stator blade 1, wherein the range of the head end region 241 is the region which is 1/6-1/8 of the length d of the tip end 245 and is the distance d1 of the parallel movement of the side line of the head end region 241 inwards on the side of the tip end 245, so that the head end region 241 can be ensured to contain the whole boundary region of the arc of the head end 11, and the range of the tail end region 243 is the region which is 1/5-1/8 of the length d of the tip end 245 and is the distance d2 of the parallel movement of the side line of the tail end region 243 inwards on the side of the tip end 245, so that the tail end region 243 can be ensured to contain the thin-walled region (the thickness is within 3 mm) of the tail end 12.
On the basis of the top block 24 polished in the step a, the intermediate region 242 is polished to 0-0.3mm, and the smooth transition between the intermediate region 242 and the head end region 241 and the tail end region 243 is ensured, so that the head end region 241 and the tail end region 243 are firstly contacted with the material during the punching process, and the close fit between the head end region 241 and the tail end region 243 is ensured.
And step C, uniformly grinding and removing the head end region 241 of the top block 24 in the step B by 0.1mm, and ensuring smooth transition of the head end region 241 and the middle region 242. This completes the repair of the top block 24. The head end region 241 is continuously polished for 0.1mm, so that the tail end region 243 can be ensured to form a support firstly in the punching process, namely, the weakest edge of the material is cut firstly to form the tail end 12, and the phenomenon that the thin edge is curled due to uneven punching force caused by different thicknesses of the edges when the material is punched is avoided if the thick and thin edges of the material participate in punching at the same time. This ensures that the trailing end 12 is not crimped.
The repair method of the punching die for the stator blade of the compressor provided by the invention solves the problem of easy punching and curling of the blade due to the structural characteristics of the blade, ensures the punching quality of the blade, and simultaneously ensures the punching manufacturability of the punching die and the stability of the quality of the blade product.
