Description

A kind of bender

Technical field

The invention belongs to sheet metal contour machining equipment technical field, be specifically related to a kind of bender.

Background technology

The equipment that existing sheet metal processing and forming generally uses is bender, and the front/rear working state schematic representation of bending as shown in Figure 1, 2 (1-patrix, 2-counterdie, 3-hydraulic jack, 4-workpiece).The principle of bender be utilize the V-shaped groove of counterdie 2 and patrix 1 extruded, shortcoming is: (1), profile angle are fixing; (2), shaping time the shaping both sides of workpiece 4 all want forming V-shape to move, be unfavorable for automation mechanized operation; (3), shaping time workpiece 4 be slide in the V-shaped groove of counterdie 2, workpiece 4 size be not easy ensure; (4), during shaping slip, there is scuffing on workpiece 4 surface; 5, can not downward bending.

Summary of the invention

The object of the present invention is to provide and a kind ofly can overcome the GIGAbend Folding System that defect both deposited by existing bender.

For achieving the above object, the technical scheme taked of the present invention is as follows:

A kind of bender: comprise the front patrix and front counterdie that are oppositely arranged up and down respectively successively from left to right, rear patrix and rear counterdie, sliding way and glide path, separate between front patrix and front counterdie, and front counterdie is stuck-module, front patrix is module that can be up and down, the right opposite end of rear patrix and rear counterdie is connected as a single entity by connecting plate, opposite end, left side is relatively independent, being provided with between sliding way and glide path can along sliding way, the slide block that glide path horizontally slips, connecting plate is connected to the left end of slide block by axle, connecting plate on the left of axle is provided with relatively-stationary first eccentric wheel with slide block, the right-hand member of slide block is provided with the second fixing eccentric wheel of relative up and down slideway, the shape of wherein said connecting plate and rear patrix, the shape of rear counterdie is suitable and connecting plate is the arc-shaped suitable with axle near the side of axle, first eccentric wheel, the second eccentric wheel are connected with motor or lever respectively separately.

Preferably, front patrix is connected with air pressure or fluid pressure drive device.

In the present invention, the effect of front patrix and front counterdie is workpiece pressing, the product of shaping various shape, and therefore, the shape of patrix and front counterdie can carry out Aided design according to shape of product demand; The effect of rear patrix and rear counterdie is the bending pressure applying anticipated orientation to workpiece, rear patrix and rear counterdie can install the mould of respective shapes additional, mould does not do particular/special requirement, as long as the convenient bending pressure applied up or down, but as preferred: rear patrix is inverted V-shaped, and rear counterdie is V-shaped.

Advantage of the present invention is:

1, profile angle can adjust arbitrarily;

2, time shaping, workpiece long end is motionless, is beneficial to Automated condtrol;

3, time shaping, workpiece is compressed motionless by upper and lower mould, and compact dimensions is guaranteed

4, surface of the work is not easy to scratch;

5, workpiece need not reverse and just can realize downward bending;

6, convenient and automation control system combines;

7, shaping efficiency is high, saves the energy.

Detailed description of the invention

As in Figure 3-5, a kind of bender: comprise the front patrix 5 and front counterdie 6(that are oppositely arranged up and down respectively successively from left to right for shaping V-arrangement bending product, both working ends be horizontal positioned split half Split V-shaped), rear patrix 7(is inverted V-shaped) and rear counterdie 8(V-shaped), sliding way 9 and glide path 10, separate between front patrix 5 and front counterdie 6, and front counterdie 6 is stuck-module, front patrix 5 is module that can be up and down, be connected with fluid pressure drive device (omitting in figure), the right opposite end of rear patrix 7 and rear counterdie 8 is connected as a single entity by connecting plate 11, opposite end, left side is relatively independent, being provided with between sliding way 9 and glide path 10 can along sliding way 9, the slide block 12 that glide path 10 horizontally slips, connecting plate 11 is hinged on slide block 12 left end by axle 13, connecting plate on the left of axle 13 is provided with the relatively-stationary first eccentric wheel 14(i.e. rotating shaft of the first eccentric wheel 14 with slide block 12 and is fixed on slide block 12), slide block 12 right-hand member is provided with the second eccentric wheel 15(i.e. rotating shaft of the second eccentric wheel 15 that relative up and down slideway fixes and is fixed in the frame of periphery), wherein, the shape of described connecting plate 11 and rear patrix 7, the shape of rear counterdie 8 is suitable and connecting plate 11 is the arc-shaped suitable with axle 13 near the side of axle 13, first eccentric wheel 14, second eccentric wheel 15 is connected with motor (omitting in figure) respectively separately.

Operation principle is: front patrix 5 is active module, and move up and down, front counterdie 6 is fixture, irremovable.Sheet metal workpiece 4 is placed on front counterdie 6, front patrix 5 slide downward workpiece pressing 4.Utilize the first eccentric wheel 14 to rotate and make rear patrix 7, rear counterdie 8 with axle 13 for the center of circle moves up and down, outstanding for sheet metal workpiece 4 front patrix 5, the bending up or down of front counterdie 6 part.Utilize the rotation of the second eccentric wheel 15, band movable slider 12 horizontally slips along sliding way 9 and glide path 10, thus changes bending angle.Indicate: front patrix 5 slides and utilizes hydraulic-driven, and the rotation of the first eccentric wheel 14, second eccentric wheel 15 utilizes motor to drive; First eccentric wheel 14 moves along with the movement of slide block 12, and the second eccentric wheel 15 can not move along with the movement of slide block 12; Rear patrix 7, rear counterdie 8 and connecting plate 11 form one mould bases.
