Abstract

The invention discloses a lifting lug reinforcing plate blanking mechanism and an application method of the lifting lug reinforcing plate blanking mechanism. An annular flat plate is arranged on a rubber block. The horizontal height of the annular flat plate is larger than that of a lower die fixing plate. When a material plate moves downwards along with a stamping die, the rubber block is compressed and deformed, the annular flat plate moves downwards accordingly, after the material plate is blanked through the stamping die, the annular flat plate is matched with the lower die fixing plate, roll rims or protrusions possibly generated on the edges of remaining materials are eliminated, quality of next blanking of the material plate is guaranteed, meanwhile material waste is reduced, and production cost is reduced.

Description

A kind of hanger stiffener blanking mechanism and using method thereof
Technical field
The present invention relates to diel field, specifically refer to a kind of hanger stiffener blanking mechanism and using method thereof.
Background technology
Sheet metal component has lightweight, intensity is high, conduction (can be used in electromagnetic shielding), cost is low, the features such as scale of mass production performance is good, at present at electronic apparatus, communication, auto industry, the fields such as medicine equipment are widely applied, the material of sheet metal component comprises: common cold-reduced sheet, SPCC refers to that steel ingot becomes steel plate coiled strip or the sheet stock of required thickness through cold-rolling mill continuous rolling, SPCC surface without any protection, be exposed in air very easily oxidized, particularly oxidation rate is accelerated in a humid environment, there is bolarious iron rust, will spray paint in surface in use, electroplate or other protection, galvanized steel plain sheet, the ground of SECC is general cold-rolled steel coils, at continuous electroplating zinc, produce line after degreasing, pickling, plating and various post-treatment process, become electrogalvanizing product, SECC not only has the mechanical performance of general cold rolling steel disc and approximate processability, and has superior corrosion resistance and decorative appearance.On the market of electronic product, household electrical appliances and furniture, have very large competitiveness and substituted, that for example current computer housing is generally used is exactly SECC; Hot-dip galvanized steel sheet, galvanizing by dipping coil of strip refers to hot rolling acid-cleaning or cold rolling rear semi-finished product, process cleaning, annealing, approximately 460 ° of C of immersion temperature dissolve in zinc groove, and make steel disc plate zinc layer, then form through modified leveling and chemical treatment.
For example, in the stamping procedure of hanger stiffener, stamping die is when carrying out stamping-out to material plate, remove the sheet metal component that stamping-out falls, in leftover materials panel edges, there will be obvious crimping or projection, make material plate when upper once stamping-out, cause the Quality Down of sheet metal component, and the raw materials consumption of meeting increment flitch, production cost increased; Yet when stamping die and material plate contact action, can there is deformation in the buffer structure of conventionally installing on die shoe, in die shoe, produce mutually and interfere with die shoe inwall, in the situation that the reconditioning quality of upper and lower die holder is very little, buffer structure can not reach predetermined buffering effect, finally causes stamping procedure normally to carry out.
Summary of the invention
The object of the present invention is to provide a kind of hanger stiffener blanking mechanism and using method thereof, avoid the remainder edge of material plate after punching press to occur that the situations such as crimping or projection occur, and reduce the loss of material.
Object of the present invention is achieved through the following technical solutions:
A kind of hanger stiffener blanking mechanism and using method thereof, material plate is placed on the annular formation plate on counterdie fixed head, stamping die is under the drive of driving arrangement, stamping die is moved toward die shoe in through hole, when stamping die contacts with material plate, annular formation plate supports the major part of material plate, stamping die continues to move down, block rubber is stressed compressed, produce certain deformation, starting provides buffering to material plate and die shoe, reduce the impact of stamping die to die shoe, material plate stamping-out is become after required plate shape, stamping die moves up, waste material residue after being stamped is directly discharged by relief hole, when block rubber generation deformation, deformation block rubber volume later increases, and block rubber is placed on counterdie fixed head, has prevented between miscellaneous part, producing mutually and interfering in block rubber and die shoe, makes the normal stable work of the present invention, annular formation plate is placed on block rubber, and the level height of annular flat monoblock is higher than the level height of counterdie fixed head, when material plate moves down with stamping die, the compressed generation deformation of block rubber, annular formation plate also moves down thereupon, and when stamping die is by after material plate stamping-out, annular formation plate coordinates with counterdie fixed head, the issuable crimping in the edge of leftover materials or projection are eliminated, guaranteed the quality of stamping-out next time of material plate, wherein upper bolster is connected by locating dowel with die shoe, in described upper bolster, stamping die is installed, on described upper bolster, upper mould fixed plate is installed, counterdie fixed head is installed on described die shoe, between upper mould fixed plate and upper bolster, be provided with backing plate, backing plate and upper bolster, upper mould fixed plate are connected by screw, on upper mould fixed plate, have through hole, stamping die is placed in through hole through upper bolster, two block rubbers are installed on described counterdie fixed head, annular formation plate is installed on block rubber, also comprise relief hole, described relief hole runs through die shoe and counterdie fixed head.When the present invention works, can guarantee the quality of stamping-out next time of material plate, reduce material waste simultaneously, reduce production costs.
