Description
Technical field
The invention belongs to die cutting die technical fields, and in particular to die cutting die is used in a kind of production of automobile parts.
Background technique
Accessory on automobile, such as part sheet metal component and soft interior trim, are typically punched by Integral die,
Punching is to apply pressure to material using the mold of installation on a hydraulic press at room temperature, it is made to generate separation or plastic deformation,
To be cut into a kind of pressure processing method of finished product.It before being punched out processing to automobile parts, needs to position it, to improve
The accuracy of Punching Technology, usually only setting positioning slot structure is positioned existing automobile parts die cutting die, however is positioned
Slot is stationary structure, and the finished product after punching sinks into be difficult to take out in locating slot, reduces production efficiency, be unfavorable for mass,
Continuous production.In addition, existing die cutting die does not have automatic waste discharge material structure, artificial waste discharge low efficiency.
Summary of the invention
The object of the present invention is to provide a kind of automobile parts production die cutting dies, can using present invention punching automobile parts
Facilitate and takes out finished workpart and automatic waste discharge, high production efficiency, high degree of automation.
The present invention provides the following technical solutions:
A kind of automobile parts production die cutting die, including die holder, die holder are fixedly arranged above lower die and at least two guide posts,
Guide post is respectively in the left and right sides of lower die；It is embedded with the upright limit plate of muti-piece in lower die, protrudes from lower die at the top of limit plate,
The upper surface of lower die is placed with workpiece, and workpiece is embedded between muti-piece limit plate, and limit plate includes fixed plate and movable plate, activity
The lower end of plate is connected with miniature lifting motor, and lifting motor can drive movable plate to rise from lower mould surface or retraction lower die,
Controller is installed, controller connects lifting motor on die holder；Be additionally provided with relief hole in lower die, relief hole longitudinally run through lower die and
Die holder, photoelectric sensor is equipped on the side wall of relief hole, and the movement that waste material is discharged through relief hole can be detected in photoelectric sensor
Signal, photoelectric sensor connect controller；Cope plate is equipped with above lower die, the bottom of cope plate is fixed with leads with what guide post cooperated
Set, guide sleeve can be moved up and down along guide post；The bottom of cope plate is further fixed on cutting head, relief hole be located at cutting head just under
Side；The top of cope plate is equipped with the connector fixed with hydraulic press.Workpiece is placed between limit plate, work can be quickly positioned
Part, and prevent workpiece in punching engineering from generating displacement；Start hydraulic press and depress cope plate, after the cutting head undershoot on cope plate
Specific position on workpiece is punched out, by relief hole discharge die holder lower section, waste material is fallen the waste material of punching by relief hole
During trigger photoelectric sensor, photoelectric sensor detects the signal that waste material falls and is sent to controller, controller
It sends and orders to lifting motor, driving movable plate decline, and then in retraction lower die；After movable plate is fallen, can be convenient under
The finished product being punched is taken out on mould, without plucking out finished product out of limit plate.
Preferably, cope plate includes the upper mold base plate being from top to bottom arranged, upper mould fixed plate, spring upper mounting plate and spring

Limiting slot, the centre of buffer board are equipped with the second through-hole passed through for cutting head.When cope plate pushes, the top protrusion of limit plate
Enter in limiting slot in the part of lower die upper surface, cope plate will not be withstood, to avoid the top of limit plate by cope plate pressure
It is bad.
Preferably, the bottom surface of buffer board, which is additionally provided with, is located at work with the height of workpiece and the matched dashpot of shape, dashpot
The surface of part.In blanking process, workpiece is pushed down automatically into dashpot by dashpot, the contact surface of workpiece and dashpot
Product is big, therefore will not make high-frequency seism in up and down direction and move, so that the smooth of the edge of die cut edge is neat, ensure that the product of punching
Matter.
Preferably, buffer board is rubber material.
Preferably, the bottom of spring upper mounting plate is also symmetrically fixed at least two stroke limit columns, stroke limit column
It can move up and down through spring lower installation board and relative to spring lower installation board；Multiple and stroke limit column is equipped on the upside of lower die
Matched stroke limit slot, the bottom end of stroke limit column can resist the slot bottom of stroke limit slot；The depth of movable chamber is greater than stroke
The groove depth of limiting slot.The stroke limit groove depth that can be suitble to according to the thickness design of workpiece, after the completion of the punching movement of cutting head,
It after stroke limit column is inserted into the slot bottom of stroke limit slot, that is, limits cutting head and continues to move downward, avoid cutting head generation
Backlash and reduce punching efficiency and increase energy consumption.
Preferably, the useless case of collection has been removably installed below relief hole, waste material is automatically drained out by relief hole to the useless case of collection,
It will not be scattered everywhere, collection is facilitated to transport.
The beneficial effects of the present invention are:
1, limit plate of the invention limits workpiece, and after completing punching, the movable plate in limit plate can be fallen automatically,
Facilitate taking-up workpiece, high production efficiency, high degree of automation.The waste material of punching is discharged by relief hole automatically under the effect of gravity,
Artificial waste discharge, high production efficiency are not needed.
2, spring and steel column can absorb the vibration that cope plate high speed stamping generates, and advantageously form smooth neat punching
Face.
3, the top cooperation of the limiting slot and limit plate of buffer board bottom, the surface engagement of dashpot and workpiece, punching are steady
It is qualitative good.
