Description
Technical field
The present invention relates to a kind of stamping device more particularly to a kind of stamping devices of automatic charging.
Background technique
Punch forming has become a kind of processing method very universal in machining.Presently mainly with artificial side
Formula feeding needs to handle by several times, and cost of labor is higher；In addition stamping die is fixed, bad adjustment and disassembly.
Chinese patent publication No. be CN104985071A a kind of press machine with automatic charging function, including bracket and
Upper die bracket, bracket be equipped with telescopic device and feeding belt, bracket be equipped with feeding baffle and postive stop baffle, postive stop baffle with
Feeding baffle is parallel, and punching press lower die is placed between postive stop baffle and feeding baffle, and punching press upper mold is connected with upper mold fixed block, upper mold
Horizontal slide rod and lead screw are connected on fixed block, horizontal slide rod and lead screw both ends are arranged on vertical sliding seat, vertical sliding
Seat cooperates with upper die bracket.This press machine is the semi-finished product by plate ruling at predetermined shape, is sent on press machine rushes later
It is molded.
This press machine realizes the automatic charging of workpiece and the position of adjustable punching press upper mold make punching press upper mold and
The alignment of punching press lower die.
But the postive stop baffle position of this device is fixed, and different size of workpiece is needed to readjust postive stop baffle
Position, the push direction of driving means do not have a postive stop baffle, and workpiece can still generate deviation when push.
Summary of the invention
It does not need to adjust again the invention is intended to provide a kind of stamping device of automatic charging, when so as to push different workpiece
The position of whole postive stop baffle, while three directions of workpiece are limited.
In order to achieve the above objectives, base case of the invention is as follows: a kind of stamping device of automatic charging, including upper branch
Frame, lower bracket, upper bracket slidably connect two horizontal location bars, and locating rod is equipped with fixed module, and fixed module is slidably connected
On the securing lever, lower bracket be equipped with conveyer belt, gag lever post, driving means and punching press lower die, conveyer belt be located at driving means with
Between punching press lower die, postive stop baffle is installed on lower bracket, postive stop baffle side on a moving belt, postive stop baffle and driving means
It is parallel to push direction, vertical circular shaft is equipped on the downside of fixed module, is cased with bearing on circular shaft, bearing inner race is fixed on circular shaft, axis
Bearing outer-ring is fixed with first gear；Mould bases is provided with interior perforation, and interior perforation is engaged with first gear；It is threaded on the downside of mold changing frame
Two punching press upper molds, punching press upper mold are located at mold changing frame both ends；Lower bracket is equipped with first hydraulic cylinder, second hydraulic cylinder and third liquid
Cylinder pressure, first hydraulic cylinder is identical with second hydraulic cylinder and symmetrical about punching press lower die, and it is hydraulic that third hydraulic cylinder is located at first
On cylinder and the perpendicular bisector of second hydraulic cylinder, the sectional area of third hydraulic cylinder is twice of first hydraulic cylinder sectional area；First is hydraulic
Cylinder, second hydraulic cylinder, third hydraulic cylinder piston rod be directed to the axis of punching press lower die, on the piston rod of first hydraulic cylinder respectively
Equipped with the first gripping block, second hydraulic cylinder piston rod on be respectively equipped with the second gripping block, third hydraulic cylinder piston rod on set
There is third gripping block, the first gripping block, the second gripping block, the axial line distance of third gripping block to punching press lower die are equal；First folder
It is equipped with spring between tight block and the second gripping block, spring one end is connect with the first gripping block, the spring other end and the second gripping block
Connection；First hydraulic cylinder, second hydraulic cylinder, third hydraulic cylinder be single-rod cylinder, first hydraulic cylinder, second hydraulic cylinder without bar
Chamber is connected to the rod chamber of third hydraulic cylinder by hose.
The principle of this programme is: since fixed module lower end is equipped with vertical circular shaft, circular shaft is equipped with bearing, bearing inner race
It is located on circular shaft, bearing outer ring is located in first gear, and first gear can rotate on circular shaft, and mold changing frame is provided with and the first tooth
The identical interior perforation of wheel diameter, first gear are engaged in interior perforation, and mold changing frame can be rotated around circular shaft；Due under mold changing frame
End be threadedly coupled two punching press upper molds, when needing using different punching press upper molds, rotation mold changing frame can more mold exchange, replacement
It is convenient；Since chain is connected to spring between the first gripping block, the second gripping block, workpiece is by the first gripping block, the second gripping block to two
While spring tension makes the first gripping block and the second gripping block have clamping action to workpiece when pushing open；Due to the first gripping block and the
The piston rod connection of one hydraulic cylinder, the piston rod of the second gripping block and second hydraulic cylinder connect, and first hydraulic cylinder is that single pole is hydraulic
Cylinder, first hydraulic cylinder without cylinder it is intracavitary be full of hydraulic oil, first hydraulic cylinder is identical with the second hydraulic rod structure, and third is hydraulic
It is full of hydraulic oil in the rod chamber of cylinder, first hydraulic cylinder, second hydraulic cylinder without cylinder chamber and third hydraulic cylinder have cylinder chamber to pass through
Hose connection, when the piston rod of first hydraulic cylinder, second hydraulic cylinder shrink it is identical apart from when, it is first hydraulic cylinder, second hydraulic
Hydraulic oil in cylinder flows into the rod chamber of third hydraulic cylinder by hose, since the sectional area of third hydraulic cylinder is first hydraulic cylinder
The piston rod of twice of sectional area, third hydraulic cylinder can be withdrawn into cylinder bucket, and the piston rod of third hydraulic cylinder withdraws distance and the
The mobile distance of the piston rod of one hydraulic cylinder is identical, due to the first gripping block, the second gripping block, third gripping block to punching press lower die
Axis is equidistant, first hydraulic cylinder, second hydraulic cylinder, third hydraulic cylinder piston rod will drive gripping block movement it is identical
Distance fixes three faces of workpiece by the first gripping block, the second gripping block, third gripping block respectively, makes workpiece can be with precise positioning
Above to stamping die.
The advantages of this programme is: compared with stamping die is removed more mold exchange, this programme will need mold to be used pre-
First be threaded in mold changing frame on, when needing replacing mold, it is only necessary to Rotation With Changing mould bases can quick-replaceable punching press upper mold,
Easy to operate, replacement is convenient, improves production efficiency；Compared with the locating piece of fixed position, workpiece is pushed into the first gripping block, the
When between two gripping blocks, because the first gripping block, the second gripping block, to the mobile identical distance in two sides, workpiece will not occur partially
It moves, improves the qualification rate of work pieces process, reduce production cost；Compared with only there are the positioning device of baffle in two sides, first is clamped
When block, the second gripping block both sides are mobile, third gripping block can move identical distance under the action of hydraulic cylinder, make the of workpiece
Three directions are fixed, and keep the locating effect of workpiece more preferable；Since the first gripping block, the second gripping block, third gripping block are all
Movably, driving means can be sent into the workpiece of different specifications, not need the position of adjustment gripping block, easy to use, mention
High efficiency.
