Abstract

A forming, trimming and flanging combined die structure comprises a material pressing plate, a material pressing plate spring, a convex and concave die, a workpiece pushing plate, an upper die plate, a die shank, a workpiece pushing plate spring, a workpiece pushing plate screw, a material pressing plate screw, a concave die, a lower die plate, an ejector, an ejector spring and a convex die. The material pressing plate is connected to the upper die plate through the material pressing plate screw, the material pressing plate spring is installed between the upper die plate and the material pressing plate, the convex and concave die is fixed to the upper die plate, the workpiece pushing plate is connected to the upper die plate through the workpiece pushing plate screw, and the workpiece pushing plate spring is installed between the upper die plate and the workpiece pushing plate; the die shank is installed on the upper die plate to form the upper die part, the concave die, the ejector and the convex die are sequentially installed on the lower die plate, the ejector spring is installed between the lower die plate and the ejector to form the lower die part. The three process contents of forming, trimming and flanging on one workpiece can be finished through the set of dies in one stroke of punching equipment, production efficiency is improved, and manufacturing cost and production cost of the dies are reduced.

Description

Moulding deburring flanging composite die structure

Technical field

The utility model belongs to mould applications, relates to a kind of composite punching die structure, relates in particular to a kind of moulding deburring flanging composite die structure.

Background technology

In the punch process of automobile, Tractor Body Metal Sheets, needs due to product-forming and assembling, most of workpiece all will pass through the multi-step forming processes such as drawing and moulding, trimming and piercing die, flanging and restriking and just can complete, and every one stamping procedure all needs diel, pressing equipment and the corresponding operating personnel of a set of correspondence.Like this, not only cause that labor productivity is low, frock and production cost improve, because needs multiple working procedure is produced, workpiece need repeatedly be carried and resetting simultaneously, easily causes the decline of the unstable and product quality of workpiece size.

Utility model content

The purpose of this utility model is: although according to the moulding of automobile, Tractor Body Metal Sheets with assembling needs and the profile more complicated size of some workpiece feature of standard relatively, provide the moulding deburring flanging composite die structure of a kind of moulding that completes successively workpiece in the one stroke of pressing equipment, deburring, overturning process.

The technical solution of the utility model is: moulding deburring flanging composite die structure, comprises; Holding pad, holding pad spring, punch-die, push piece plate, cope match-plate pattern, die shank, push piece flat spring, push piece plate bolt, holding pad screw, die, lower bolster, backing-out punch, backing-out punch spring, punch; Holding pad is connected on cope match-plate pattern by holding pad screw, holding pad spring is installed between cope match-plate pattern and holding pad; Punch-die is fixed on cope match-plate pattern; Push piece plate is connected on cope match-plate pattern by push piece plate bolt, between cope match-plate pattern and push piece plate, push piece flat spring is installed; Die shank is arranged on cope match-plate pattern, forms part of the upper die; Die, backing-out punch, punch are installed on lower bolster successively; Backing-out punch spring is installed between lower bolster and backing-out punch, forms part of the lower die.

The utility model adopts the good effect producing after technique scheme to be: utilize moulding deburring flanging composite die to utilize a mold to complete in the one stroke of pressing equipment the shaping of a workpiece, deburring, three technique contents of flange, improve production efficiency, reduced mould manufacturing expense and production cost.This moulding deburring flanging composite die is simple and practical, manufacture and easy to maintenance, the production in enormous quantities of applicable workpiece.

Fig. 2 is that the master of the utility model moulding deburring workpiece that flanging composite die is produced looks schematic diagram;

Fig. 3 is the schematic top plan view of the utility model moulding deburring workpiece that flanging composite die is produced.

The specific embodiment

The utility model is described in further detail with reference to the accompanying drawings below.As shown in Fig. 1 ~ 3, moulding deburring flanging composite die structure, mainly comprises; Holding pad 1, holding pad spring 2, punch-die 3, push piece plate 4, cope match-plate pattern 5, die shank 6, push piece flat spring 7, push piece plate bolt 8, holding pad screw 9; Above part is all connected on cope match-plate pattern 5, forms the part of the upper die of mould, and part of the upper die is installed on the slide block of pressing equipment; Also have die 10, lower bolster 11, backing-out punch 12, backing-out punch spring 13, punch 14, above part is all connected on lower bolster 11, forms the part of the lower die of mould, and part of the lower die is installed on the workbench of pressing equipment.

Before work starts, open part of the upper die and the part of the lower die of mould, and part of the upper die stops at the top of equipment with the slide block of pressing equipment, and holding pad 1 is in and concordant position, punch-die 3 bottoms under the acting in conjunction of holding pad spring 2 and holding pad screw 9; Push piece plate 4 is in and concordant position, punch-die 3 bottoms under the acting in conjunction of push piece flat spring 7 and push piece plate bolt 8; Part of the lower die is arranged on the workbench of pressing equipment and maintains static, and backing-out punch 12 is in and concordant position, punch 14 tops under the effect of backing-out punch spring 13.

Work starts, operating personnel are placed on the stock of workpiece 15 on the backing-out punch 12 of counterdie, part of the upper die is with slide block down, punch-die 3 contacts with backing-out punch 12, and workpiece pressing 15 stocks, patrix continues Bottom Runby h with slide block, goes out the top of workpiece at the effect compacted under of punch-die 3 and punch 14, completes the moulding of workpiece 15; Patrix continues descending with slide block, punch-die 3 contacts with die 10, cuts out the profile of workpiece, completes the deburring of workpiece 15; Patrix continues descending with slide block, under the effect of punch-die 3 and punch 14, complete the flange of workpiece 15, and whole technique contents of workpiece 15 complete; Part of the upper die starts up with slide block subsequently, open part of the upper die and the part of the lower die of mould, backing-out punch 12 ejects workpiece 15 under the effect of backing-out punch spring 13 from punch 14, operating personnel take out workpiece 15 from mould, completes the punching production process of a workpiece.

In punching production, utilize this moulding deburring flanging composite die structure, easy to operate, production process is few, and production efficiency is high.
