Abstract
The invention discloses a stamping compound die for a filter end cover. The stamping compound die comprises an upper die and a lower die, wherein the upper die comprises a die shank; the lower end of the die shank is fixedly connected with an upper die bottom plate, an upper die fixing plate and a flanging die in sequence; the outer edge of the bottom surface of the flanging die is sunken upwards; the outer edge of the bottom surface of the upper die fixing plate is sunken upwards to form a step; the top of the flanging die is matched with the step; the outer edge of the bottom surface of the flanging die is sunken upwards, so that when the upper die and the lower die are assembled, a gap is formed between the outer edges of the flanging die and a stripper plate, and only the inside parts of the flanging die and the stripper plate are in contact; the stamping pressure is concentrated on a knockout block and a punch die, so that the stress is reasonably distributed, and the forming of the filter end cover is more facilitated; and besides, the step formed by the upper die fixing plate is matched with the flanging die to limit the flanging die, and the concentricity of the upper die is improved, so that the stamping accuracy is improved, and the quality of the filter end cover is ensured.
Description
Technical field
The present invention relates to field of filter production equipment, specifically a kind of end cover of filter punching compound die.
Background technology
Known, cleaner is mounted in the visual plant in vehicle, will enter the objectionable impurities in oil circuit or gas circuit for filtering.End cover of filter is one of critical piece of cleaner, and end cover of filter is generally by making tablet punching press.Traditional preparation process adopts two groups of moulds usually, is completed the processing of end cap, in order to Simplified flowsheet by twice stamping procedure, and the orientation problem repeatedly between stamping procedure, main employing compound die compound two kinds of stamping procedures at present, one-shot forming, completes the making to end cover of filter.But in use find, the unreasonable distribution of this compound die stress when matched moulds, concentricity is also bad in addition, thus affects the quality of end cover of filter.
Summary of the invention
The object of the present invention is to provide a kind of end cover of filter punching compound die, the stress distribution of this compound die when matched moulds is reasonable, has good concentricity simultaneously, improves the quality of end cover of filter.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of end cover of filter punching compound die, comprise patrix and counterdie, described patrix comprises die shank, and die shank lower end has been fixedly connected sequentially upper baffle plate, upper mould fixed plate and flange die; The bottom surface outer rim of described flange die upwards caves in; The bottom surface outer rim of described upper mould fixed plate is upwards recessed to form step, and the top of described flange die is formed with described step and coordinates.
The invention has the beneficial effects as follows, the bottom surface outer rim of flange die upwards caves in, make patrix and counterdie when matched moulds, the stripper of flange die and counterdie forms gap in outer rim, flange die only contacts in inboard portion with stripper, pressure during punching press is concentrated on the punch-die of dnockout block and counterdie, and stress distribution is reasonable, is more conducive to the shaping of end cover of filter; In addition, the step that upper mould fixed plate is formed matches with flange die, plays position-limiting action to flange die, improves the concentricity of patrix, thus degree of accuracy when improving punching press, ensure the quality of end cover of filter.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is working state schematic representation of the present invention;
Fig. 3 is the enlarged diagram at A place in Fig. 2;
Fig. 4 is the enlarged diagram at B place in Fig. 2.
Detailed description of the invention
As shown in Figure 1, the invention provides a kind of end cover of filter punching compound die, comprise patrix 1 and counterdie 2, described patrix 1 comprises die shank 1a, and die shank 1a lower end has been fixedly connected sequentially upper baffle plate 1b, upper mould fixed plate 1c and flange die 1d; Also be connected with punching concave die 1e below upper mould fixed plate 1c, the lumen centers of punching concave die 1e is provided with drift 1h, is provided with dnockout block 1f and punching press rubber blanket 1g between flange die 1d and punching concave die 1e.Described counterdie 2 comprises lower mould bottom plate 2a, lower mould bottom plate 2a top is fixedly connected with counterdie fixed head 2b, the first punch-die 2c with dnockout block 1f corresponding matching is provided with in counterdie fixed head 2b, first punch-die 2c lumen centers is provided with the second punch-die 2f with drift 1h corresponding matching, counterdie top is the stripper 2d with flange die 1d and punching concave die 1e corresponding matching, be provided with the first material returned rubber blanket 2e between stripper 2d and counterdie fixed head 2b, between stripper 2d and the first punch-die 2c, be also provided with the second material returned rubber blanket 2g.
The bottom surface outer rim of described flange die 1d upwards caves in; The bottom surface outer rim of described upper mould fixed plate 1c is upwards recessed to form step, and the top of described flange die 1d is formed with described step and coordinates.
Shown in composition graphs 2, be placed on by tablet on counterdie 2 during matched moulds, patrix 1 punching press downwards, namely obtains end cover of filter 3; Shown in composition graphs 3, in punching course, flange die 1d and stripper 2d contact completely, but form gap in outer rim, flange die 1d only contacts in inboard portion with stripper 2d, pressure during punching press is concentrated on dnockout block 1f and the first punch-die 2c, and stress distribution is reasonable, is more conducive to the shaping of end cover of filter; Shown in composition graphs 4, the step that upper mould fixed plate 1c is formed matches with flange die 1d, plays position-limiting action to flange die 1d, improves the concentricity of patrix 1, thus degree of accuracy when improving punching press, ensure the quality of end cover of filter.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention; Any those of ordinary skill in the art, do not departing under technical solution of the present invention ambit, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solution of the present invention, or be revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent replacement, equivalence change and modification, all still belongs in the scope of technical solution of the present invention protection.
