Description

A kind of fine blanking die of controllable steel back appearance and size
Technical field
The utility model belongs to auto parts machinery stamped field, more particularly to a kind of mould for carrying out steel back side dressing Tool.
Background technology
Hull formula braking brake block steel back is one of important part in automobile brake sheet, it is used for fixed friction material Material, while be installed on easy to brake block in brake system.Therefore the quality of brake block is influenced very big by steel back cross section quality, its Can plane of disruption region and its size be directly related to steel back and use and its using effect, and burr is bigger, and the plane of disruption gets over out-of-flatness, Then brake noise is bigger, and braking effect is poorer.And steel back is mainly punched using common process for stamping at present, due to blanking die The design shortcoming of tool is perfect so that a large amount of planes of disruption and burr inevitably occurs in the punching face of blanking part, so as to influence steel The performance of the back of the body;Or follow-up processing is the increase in, extend the production cycle and substantially increase production cost.Have Manufacturer using three dynamic fine blanking press punchings, obtained blanking part quality has been lifted, but considerably increases production The input of equipment and the production cost of product, are unfavorable for more specifications, enterprise's progress flexible production of small lot, so as to reduce The product competitiveness of enterprise.
Utility model content
Purpose of utility model:In order to overcome the above insufficient, the purpose of this utility model is to provide outside a kind of controllable steel back The fine blanking die of shape size, its is simple in structure, and design is reasonable, can overcome the drawing due to punching during being punched out Steel back plane deformation caused by power is pulled, can be rationally punched out according to steel back punching demand.
Technical solution:A kind of fine blanking die of controllable steel back appearance and size, including upper die and lower die, the upper mold are arranged on Lower die top;Wherein, upper mold includes upper mould fixed plate, the first cutter, the first punch-pin, the second punch-pin, the 3rd punch-pin, the 4th convex Mould, the 5th punch-pin, punch retainer, blanking plate and the second cutter, the upper mould fixed plate is connected with punch retainer, under described The lower face of flitch and punch retainer connects, and first cutter and the second cutter are connected with upper mould fixed plate, and described first Punch-pin, the second punch-pin, the 3rd punch-pin, the 4th punch-pin and the 5th punch-pin are arranged on punch retainer;The lower die is consolidated including lower die Fixed board, the first cavity plate, die block, the second cavity plate, the 3rd cavity plate, the 4th cavity plate, the 5th cavity plate, first cavity plate, Two cavity plates, the 3rd cavity plate, the 4th cavity plate and the 5th cavity plate are arranged on die block, the die block and lower mold fixed plate Connection.
The mould of the controllable steel back appearance and size of the utility model, when being punched out to steel back, according to steel back Appearance and size, devise corresponding bending mould, steel back be placed between punch retainer and die block, blanking plate and The junction of die block is arranged to the shape of steel back, so that ensure that will not destroy steel back shape when punching.
Further, the fine blanking die of above-mentioned controllable steel back appearance and size, the upper mould fixed plate and punch-pin are fixed Backing plate is equipped between plate.Backing plate is set between upper mould fixed plate and punch retainer, adds transition structure.
Further, the fine blanking die of above-mentioned controllable steel back appearance and size, the upper mould fixed plate and the second cutter Between be equipped with shop bolt.The positioning pin of setting can ensure that the installation site volume of cutter is accurate surely, so as to obtain good processing Effect.
Further, the fine blanking die of above-mentioned controllable steel back appearance and size, the upper mould fixed plate and the second cutter It is bolted.Using from top to bottom be screwed into installation bolt, the second cutter can be fixed on upper mould fixed plate.
Further, the fine blanking die of above-mentioned controllable steel back appearance and size, the steel back of this Mold Making use Steel plate thickness be less than or equal to 6mm.Will not be excessive because of punching power during in order to ensure punch-pin and cavity plate punching but bore edges go out Existing burr, it is therefore desirable to control the thickness of steel back.
Further, the fine blanking die of above-mentioned controllable steel back appearance and size, first cavity plate, the second cavity plate, The cutting edge of three cavity plates, the 4th cavity plate and the 5th cavity plate is highly 2-3 times of steel back thickness.The cutting edge height of setting can ensure rushing The complete punching of steel back can be carried out during hole, the insufficient situation of punching will not be caused, while ensure that the internal surface of hole of punching Precision.
Further, the fine blanking die of above-mentioned controllable steel back appearance and size, the blanking plate and die block it Between blade clearance for steel back thickness 0.15%-0.2% between.The blade clearance of setting be in order to ensure in engineering is punched, Less gap can ensure the shape of steel back, avoid causing steel back flatness poor.
Above-mentioned technical proposal can be seen that the utility model and have the advantages that:It is described in the utility model controllable The fine blanking die of steel back appearance and size processed, its is simple in structure, and design is reasonable, is readily produced.The essence of controllable steel back appearance and size Stamping die can ensure to be punched out during, the flatness of steel back.
