Technical field
The invention belongs to diel field, in particular, relate to a kind of punch level progressive die centering block and rotate the anti-rebound shaped structure of negative angle that takes all of.
Background technology
Along with growth in the living standard, the market demand of household electrical appliances is increasing in recent years, and the demand that sheet metal component is manufactured field at household electrical appliances is also increasing, and the requirement of the product quality to sheet metal component also more and more comes high, especially more strict to the requirement of panel beating appearance member.Conventionally the larger sheet metal component of product size all adopts single die to manufacture, production efficiency is low, process part processing flow in the process of subsequent processing from a upper operation, outward appearance to product and quality are easy to cause damage, requirement for production operator is also very high, cause producing a large amount of defective products, had a strong impact on the production efficiency of enterprise.
Summary of the invention
For overcoming the deficiencies in the prior art part, the invention provides a kind of punch level progressive die centering block and rotate the anti-rebound shaped structure of negative angle that takes all of, can realize and in multi-station progressive die, rotate the negative angle formation that takes all of.
The technical solution adopted in the present invention is: a kind of centering block rotary forming structure of cold punching die, comprise punch level progressive die and shaping centering block, described shaping centering block has axis hole, is provided with and its sliding rotating shaft of joining in this axis hole, and the described rotating shaft other end is located by rotating shaft holder; Described shaping centering block below is provided with negative angle formation working face, for product is processed; Described shaping centering block upper right side is provided with inclined-plane, while rotation, steps down for the die sinking that is shaped, and avoids scratching product; Directly over described shaping centering block, be provided with shaping limit for height piece, kill rear guarantee mould strength for mould; Described shaping centering block right flank is provided with a block, kills the side force of rear described block while being shaped for eliminating when mould matched moulds, is provided with thimble spring reset mechanism in described limit for height piece, makes described centering block reset during for die sinking.
Described shaping centering block axis hole one side has screw, and described screw and shaping centering block axis hole are tangent, in described screw, holding screw are housed, for preventing that described rotating shaft from running when the centering block rotary forming.
Described thimble spring reset mechanism comprises thimble, spring and set screw, in described shaping limit for height piece, have a vertical through hole, in through hole, be provided with thimble moving up and down and described shaping centering block offsets, in the upper bolster of described punch level progressive die, have a screw, in this screw, be provided with spring, described spring pushes against with the set screw that is arranged on described screw top.
Beneficial effect: the invention has the advantages that: simple in structure, reasonable in design, handling ease, is shaped reliable, can adopt in shaping of the same type, can effectively improve the quality of products and the production efficiency of enterprise.
Brief description of the drawings
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is die opening state structural representation of the present invention.
Fig. 2 is matched moulds status architecture schematic diagram of the present invention.
Detailed description of the invention
Further illustrate the present invention below by embodiment, and the present invention is not restricted to described embodiment, all similar with structure of the present invention, and be only that size, position are adjusted or change person to some extent, all belong to protection category of the present invention.
Referring to Fig. 1, Fig. 2, a kind of punch level progressive die centering block rotates the anti-rebound shaped structure of negative angle that takes all of, comprise punch level progressive die, punch level progressive die comprises: upper bolster 1, upper padding plate 2, train wheel bridge 3, baffle plate 4, stripper 5, lower bolster 15, lower bolster 16, die shoe 17, lower padding iron 18 and shaping centering block 13, shaping centering block 13 belows are provided with negative angle formation working face for product is processed, and shaping centering block 13 upper right side are provided with when inclined-plane rotates for the die sinking that is shaped and step down; Shaping centering block 13 right flanks are provided with block 11, and when mould matched moulds is killed backstop 11, the side force while shaping for eliminating, is provided with shaping limit for height piece 10 directly over shaping centering block 13, kill rear guarantee mould strength for mould; In the middle of shaping centering block 13, have axis hole, have sliding rotating shaft 14 of joining with it in axis hole, rotating shaft 14 is joined with rotating shaft holder 6 is sliding,
Shaping centering block axis hole one side has screw, and described screw and shaping centering block axis hole are tangent, and holding screw 12 is housed in described screw, for preventing that rotating shaft 14 from running when centering block 13 rotary forming.Holding screw 12 can prevent that rotating shaft 14 from running in the time of rotary forming.
Described thimble spring reset mechanism comprises thimble 9, spring 8 and set screw 7, in described shaping limit for height piece 10, have a vertical through hole, in through hole, being provided with thimble 9 moving up and down offsets with shaping centering block 13, in the upper bolster 1 of described punch level progressive die, have a screw, in this screw, be provided with spring 8, described spring 8 pushes against with the set screw 7 that is arranged on described screw top, and during for die sinking, centering block resets;
The course of work of rotating the negative angle formation that takes all of is as follows: slider of punch is descending, stripper 5 is pushed down workpiece, shaping centering block 13 starts to touch product and starts rotary forming, along with continuing to go downwards to bottom dead centre, slider of punch is shaped, along with slider of punch is up, spring reset mechanism starts to withstand shaping centering block 13 and rotates, and the centering block that is shaped in the time of mould die sinking has turned to the region that can avoid product, thereby depart from product de-material smoothly, product shaping machines.
It should be noted that, relativeness (comprising position relationship and magnitude relationship) between each parts of describing in the accompanying drawings, be only for illustrative purposes, as long as can realize object of the present invention, can as required all parts be arranged on to the position needing.Such as, thimble spring reset mechanism, those skilled in the art can revise it, reset as long as can complete shaping centering block 13, for example, can also adopt elastomeric material etc.For a person skilled in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present invention is limited by claims and equivalent thereof.
