Abstract

A technology for processing a rotatable filter sealing ring fixed plate is completed on a die by a stamping way and comprises the following steps of punching a metal sheet, flanging the edge of the punched hole, extending the external side of the flanging part, blanking and cutting to obtain a semi-finished product; and folding the edge of the semi-finished product and the flanging position of the through hole on the semi-finished product. The technology has reasonable process; and compared with the existing machining process, the technology has the active effects of less processing and dies investment, higher productivity, lower material consumption and reject rate, and the like.

Description

Technology for processing rotatable filter sealing ring fixed plate
Technical field
The present invention relates to a kind of processing technology of rotatable filter sealing ring fixed plate.
Background technology
Sealing ring fixed plate is the vital part of rotatable filter, it with the filter casing interlock after seal.Adopt impact style to finish on mould to the processing of sealing ring fixed plate at present, existing procedure of processing to sealing ring fixed plate is: (1) carries out blanking, stretching to sheet metal; (2), carry out punching, to the edge flange in hole; (3), flanging is carried out at the flange position in hole; (4), to the deburring of half-finished edge, flanging.The shortcoming that existing this processing mode exists is: the mode that adopts the back punching that stretches earlier, the contraction on the full backup plate material of the distortion during material extending outer side edges edge is supplied with, can cause the uniformity at semi-finished product edge not good, therefore, need carry out deburring, increase the input of operation and mould like this, and also made the consumption of material increase.
Summary of the invention
The object of the present invention is to provide a kind of processing technology of rotatable filter sealing ring fixed plate, the uniformity at the sealing ring fixed plate edge during this technology can guarantee to process is preferable, and then reduces operation and the input of mould and the consumption of material.
For achieving the above object, the present invention adopts following scheme: the processing technology of rotatable filter sealing ring fixed plate, and adopt impact style on mould, to finish, may further comprise the steps: (1), sheet metal is carried out punching; (2), the edge with going out hole carries out flange, the outside to the flange position stretches simultaneously; (3), to carry out blanking die-cut, obtains semi-finished product; (4) flanging is carried out at the flange position of half-finished edge and last through hole thereof.
By such scheme as seen, the processing technology of rotatable filter sealing ring fixed plate provided by the invention, adopt first punching, and then the operation that the edge of through hole is carried out flange and the outside at flange position is stretched, when stretching, distortion of materials can be supplied with jointly by the edge in the outside and the edge of through hole, make the deflection at outer material side edge reduce greatly, and can guarantee that this deflection is in the claimed range of product, and then trimming process step can be removed from, so promptly exempted the consumption that deburring used mould has reduced material again.
Technology of the present invention is reasonable, and it is compared with existing processing technology, has actively effect such as operation and mould less investment, productivity ratio raising, material consumption reduction and percent defective reduction.
Description of drawings
The structural representation of Fig. 1 one embodiment of the invention mould therefor one;
The sealing ring fixed plate semi-finished product structure chart of Fig. 2 after by Mould Machining shown in Figure 1;
The structural representation of Fig. 3 one embodiment of the invention mould therefor two;
The sealing ring fixed plate structure chart of Fig. 4 after by Mould Machining shown in Figure 2.
The specific embodiment
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
May further comprise the steps when as seen from Figure 1, sheet metal 8 being carried out punch process by this mould:
1, in patrix moves downward at first the 1 pair of sheet metal in position 8 by patrix carry out punching;
2, cooperate the edge of realizing going out through hole to carry out flange with annular groove 4 on the patrix by the position 6 of counterdie and stretch by the outside that cooperates of blind hole 7 on the parts on the patrix 2 and the counterdie to the flange position;
3, the parts 3 by patrix are with to carry out blanking cooperating of position, counterdie edge 5 die-cut.
By obtaining sealing ring fixed plate semi-finished product 9 as shown in Figure 2 after the above step.
Semi-finished product shown in Figure 29 are put in the mould shown in Figure 3,, can be finished flanging is carried out at the flange position of half-finished edge and last through hole thereof by the punch process of this mould.The structure of the sealing ring fixed plate that finally obtains as shown in Figure 4.
Sealing ring fixed plate and the filter casing produced by processing technology provided by the invention assemble after laboratory test satisfies the industry standard requirement fully.
Processing technology step provided by the invention is reasonable in design, because it has removed the operation of deburring from, can reduce personnel and equipment use, and can reduce the consumption of material, processing technology provided by the invention adopts aborning, can reduce the processing cost of product, bring considerable economic.
