Description
Technical field
The present invention relates to plate stamping technical field, in particular to a kind of metal plate bending deformation stamping die.
Background technique
Color coated steel sheet is a kind of steel plate with organic coating；Color steel plate is divided into veneer, color-steel composite board etc., and color steel plate is wide
The general metope and roofing for being used in large public building, public workshop, movable plank house and integrated house, color steel plate have weight
Gently, the features such as intensity height, convenient and flexible installation.
The substrate of color steel plate is cold-rolled substrate, and color steel plate needs to carry out molding punching press later, so that its surface is capable of forming
Protrusion, the shape according to its different protrusion of the purposes of color steel plate is different, and color steel plate carries out forming processes and generally rushed by mold
The mode of pressure carries out, and color steel plate can only be struck out a kind of specific structure by every kind of mold, so that the color steel plate of different model needs
Punching press is carried out using different molds, increase the cost of color steel plate indirectly, it is existing to deposit when carrying out molding punching press to color steel plate
The problem of it is as follows:
1. color steel plate can only be struck out a kind of specific shape by the stamping die of color steel plate, and when mold use for a long time
Abrasion so that mold needs to regularly replace, increases the production cost of color steel plate than more serious；
Needs are manually adjusted its position when 2. color steel plate carries out punching press, when mold carries out punching press movement, color steel plate
A degree of movement can occur under the action of stamping press, and when color steel plate is placed in lower die can be recessed, and lead to coloured silk
Steel plate punched effect is poor.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of metal plate bending deformation stamping die, including bottom plate, lower die,
Cant board, upper mold, link block, limited post and limit spring are equipped with lower die on the middle part upper surface of the bottom plate, bottom plate
Limited post is symmetrically installed at the top of outer end, cant board is located at the rear side of lower die, and cant board is mounted on the rear end top of bottom plate,
Upper mold is located at the surface of lower die, is symmetrically installed with link block on the lateral surface of upper mold, in the outer end and limited post of link block
To be slidably matched between portion, the lower end outside of each limited post is distributed with a limit spring, and limit spring is mounted on limit
Between the lower end and link block of column, it is provided with limited block on the top of limited post, the present invention is placed under press machine first
Color steel plate, is placed on the upper end of lower die by end later, complete so that lower die is matched with upper mold under being acted on by the punching press of press machine
The punching press movement of pairs of color steel plate, limit spring can drive upper mold to carry out along limited post to moving up under the action of no external force
Dynamic, limited post plays the role of limit when can move up and down to upper mold, the limited block at the top of limited post can prevent upper mold from
It is popped up on limited post.
It is laterally homogeneous in the lower die to be provided with square groove, it is uniformly arranged that there are three screw threads in lower die in the lower wall of square groove
Hole is placed with a mold plate in each square groove of lower die, and the top surface of mold plate and the top surface of lower die are located at same level
Interior, thus the phenomenon that mold plate will not cause it to bend when color steel plate carries out punching press, the front end of mold plate passes through bolt
It is locked in above lower die in the threaded hole of front of the slot；
A protruding block is provided on the top of each mold plate, the middle part and rear end of protruding block are provided with one
Counterbore, the counterbore on protruding block pass through mold plate, and middle part and rear end spiral shell on the position of counterbore and the square groove of lower die on protruding block
The position of pit corresponds, and is distributed with a dormant bolt in each counterbore on protruding block, and dormant bolt is by mold plate
Middle part is locked on the square groove of lower die in the threaded hole of rear end, when specific works, the mold plate in lower die is able to carry out disassembly
Replacement, strikes out suitable shape for color steel plate so that lower die is matched with upper mold.
It is symmetrically arranged with mounting groove on the bottom of the upper mold, is symmetrically arranged with sliding slot on the side wall of upper mold mounting groove,
It is distributed with a plugboard in each mounting groove of upper mold, is slidably matched between plugboard and the mounting groove of upper mold, upper mold
Bottom surface and the lower end surface of plugboard be in same level, to increase the punching press effect of color steel plate, and the position of plugboard
It sets and is corresponded with the position of mold plate；
It is arranged fluted in the middle part of the lower end surface of plugboard, and the structure of plugboard groove is opposite with the structure of protruding block
It answers, the rear end of each mounting groove in upper mold is distributed with a barrier plate, and barrier plate is mounted on the trailing flank of upper mold, and hinders
The downside of baffle is located at the top of plugboard setting groove, and when specific works, the plugboard of upper mold upper end is able to carry out replacement,
Color steel plate is struck out to different shapes so that the groove on plugboard is matched from protruding block, after barrier plate can be to plugboard
The position at end is limited, and enables color steel plate by complete punching press.
As a preferred technical solution of the present invention, playback slot is provided on the leading flank of the cant board, it is edge-on
U-shaped board is installed, the middle part trailing flank of U-shaped board is connected with the front end of restoring spring, after restoring spring in the playback slot of plate
End is mounted on the playback slot rear wall of cant board, the cunning that the U-shaped structure of U-shaped board can be flat in the playback trough inner water on cant board
It is dynamic.
As a preferred technical solution of the present invention, the restoring spring is compressed spring, and the leading flank of U-shaped board supports
On the trailing flank of protruding block, and the top of U-shaped board is located at the top of protruding block upper end, and the front end upper side of U-shaped board is arc
Face, when color steel plate is placed on the upper end of lower die, U-shaped board can limit the position of color steel plate, so that color steel plate
Trailing flank is closely bonded with the trailing flank of protruding block, prevents the placement location of color steel plate from having deviation to cause its punching press effect difference etc.
Problem.
