Abstract

The utility model discloses a demoulding structure of a panel bending forming machine, which is characterized in that a pressed girder for installing a forming mould on the panel bending forming machine is in a lever structure, and the middle part of the pressed girder is hinged on a frame; the forming mould is installed on one end of the pressed girder, and the other end of the pressed girder is hinged with the frame through a pressure cylinder. The lifting track of the forming mould which is installed on the pressed girder is an arc which swings along with the pressed girder; when a secondarily formed workpiece shaped like a left square bracket is processed, the piston rod of the pressure cylinder is shrank to pull one end of the pressed girder to swing downwards, the other end of the pressed girder can carry the forming mould to swing upwards in an arc mode, and then, the forming mould swings out of the embedded cavity shaped like a left square bracket to realize the demoulding purpose. The demoulding structure of the panel bending forming machine has the advantages of quick demoulding speed, convenience and high efficiency.

Description

The demolding structure of plate member bent make-up machine

Technical field

The utility model relates to the demolding structure on the brake forming equipment of metal sheet, particularly metal sheet brake forming equipment.

Background technology

In the bending molding process of metal sheet, need sometimes plate is carried out post forming, plate is bent into " [" type workpiece.Through post forming " [" type workpiece, mould can be embedded in workpiece and " in [" die cavity, cause the difficulty of the demoulding and discharging, thereby influence the continuous production of machine after machining.Existing discharging method mainly contains two kinds, and a kind of is manual discharging, and its efficient is low, only is applicable to unit work, can not be used for automatic production line, and it can not satisfy the demand of the household electric appliances of production in enormous quantities; Another kind method is that the motion mode to mould improves, and the demoulding campaign of mould by original single lengthwise movement, is changed into vertically and laterally both direction motion, to realize the workpiece demoulding and discharging.This method can be used for automatic production line, yet its mould has increased a direction motion, makes mould all need to reorientate after each demoulding, and its positioning accuracy is difficult to guarantee, therefore influences the precision and the uniformity of workpiece processing easily.Simultaneously, increased the mechanism that the driving mould laterally moves, also made the demolding structure of bender become complicated more.

The utility model content

Of the present utility modelly be intended to provide a kind of being convenient in demoulding, positioning accuracy height, high conformity, and the demolding structure of plate member bent make-up machine simple in structure.

The demolding structure of plate member bent make-up machine described in the utility model, it is characterized in that: the pressure beam of installation forming mould is a lever construction on the plate member bent forming machine, press the middle part of beam to be articulated on the frame, one end installation forming mould, the other end is hinged by pressure cylinder and frame, when the flexible promotion of the piston rod of pressure cylinder pressed the coupled end of beam to swing up and down, the other end of pressure beam can carry mould and swing up and down.

The demolding structure of plate member bent make-up machine described in the utility model, it presses beam is lever construction, the lifting track that is installed on the mould of pressing beam one end is the camber line with the swing of pressure beam.When " during [" workpiece of brake forming machined post forming, by the piston rod of systolic pressure cylinder, the beam one end bottom is pressed in pulling, makes to press beam to get the other end to carry on the mould and put, mould " is showed along camber line in [" type cavity, realized the demoulding from what embed.An one wobbling action has promptly been finished the demoulding of workpiece, and the demoulding is quick and easy, efficient is high.Simultaneously, the demoulding campaign of its mould is the swing around fixed axis, and by reverse backswing, mould can be got back to original position accurately, and there is not the problem of reorientating in it, and can be good at keeping the precision and the uniformity of processing.In addition, this demolding structure is only swung the demoulding and the return of promptly having realized mould by the pressure beam of lever form, and its structure is also simpler.

Description of drawings

Fig. 1 is the structural representation of the plate member bent make-up machine of use demolding structure described in the utility model.

The specific embodiment

A kind of demolding structure of plate member bent make-up machine, as Fig. 1, the pressure beam 8 of its installation forming mould is a lever construction, the middle part is articulated on the frame 5, an end installation forming mould 7, and the other end then connects pressure cylinder 9, the cylinder body of pressure cylinder 9 and frame 5 are hinged, the then hinged pressure beam 8 of its piston rod.

Claims (1)

1, the demolding structure of plate member bent make-up machine, it is characterized in that: the pressure beam (8) of installation forming mould is a lever construction on the plate member bent forming machine, press the middle part of beam to be articulated on the frame (5), one end installation forming mould (7), the other end is hinged by pressure cylinder (9) and frame, when the flexible promotion of the piston rod of pressure cylinder pressed the coupled end of beam to swing up and down, the other end of pressure beam can carry mould and swing up and down.
