Description

Flat steel double-bending device

The technical field is as follows:

the utility model relates to a band steel processing equipment field of bending mainly relates to a band steel double bending device.

Background art:

in the field of engineering machinery, a fork truck goods blocking rack is usually formed by using flat steel as a U-shaped frame, the flat steel needs to be bent by 2-large R multiplied by 90 degrees along the lateral direction when being processed, the condition is limited by adopting an oil press die-forming die to press 90 degrees for one time, 2 persons lift parts (the weight of the parts is 13-20 Kg) and press 90 degrees in a reversing way, the flat steel formed by the method has serious unevenness, the workload of correction after pressing is large, the consistency of the bending size of the flat steel is poor during batch operation, and the use requirement cannot be met.

The above method has the following defects:

1. the operation needs many steps to be completed, 2 personnel are required to perform secondary profiling by utilizing a profiling die, the profiling positioning completely depends on the serious unevenness of the flat steel profiled by manual marking, and the workload of correction after the profiling is large;

2. because each operation process needs manual intervention, the efficiency is low, and potential safety hazards exist;

3. the mass processing has poor consistency of bending size, and manual operation and matching are needed, so that the actual requirements cannot be met.

The utility model has the following contents:

the utility model discloses the purpose is exactly in order to compensate prior art's defect, provides a two curved devices of band steel, guarantees the requirement of size uniformity, ensures that the product is once only qualified, reduces artifical intensity of labour, has improved product machining efficiency, is applicable to the curved system of fork truck fender goods shelves U type frame.

The utility model discloses a realize through following technical scheme:

the utility model provides a two curved devices of band steel which characterized in that: including the double-layered mould subassembly that two intervals set up, press from both sides the mould subassembly including two sets of cooperations of mutually corresponding last mould and lower mould, the lower mould is portable lower mould, and its up end is installed down and is pressed from both sides the mould, press from both sides the top of mould down and install rather than the complex on press from both sides the mould, press from both sides the both sides of mould subassembly and install respectively rather than complex round mould, the slide plate mould that can overturn rather than the complex is installed to the below of round mould, the upset of slide plate mould is by the cylinder drive of its one side, the lower terminal surface of going up the clamp mould, the up end of lower clamp mould, the outer periphery of wheel mould and the up end of slide plate mould are equipped with respectively and are used for clamping the draw-in groove of treating the.

The lower clamping die and the upper clamping die are respectively clamped on the guide rails of the upper die and the lower die through the guide grooves.

The lower die is driven to move by an air cylinder at the bottom end of the lower die.

The wheel mould central point put and rotate and install the pivot, the mounting panel is installed at the both ends of pivot, the bottom of mounting panel is connected rather than the slide mould that corresponds.

And the clamping grooves of the upper clamping die and the lower clamping die and the clamping grooves on the wheel die and the sliding plate die are matched to form a guide channel for the flat steel to pass through.

The principle is as follows: the device integrates the 2-large RX90 degree bending process into one device by adopting a double bending process and a die, the device can bend and form the flat steel at one time by utilizing one-man feeding of an air cylinder without heating the flat steel and a power supply, the operation is simple and flexible, the positioning is accurate, the flatness does not need to be manually corrected after bending, is particularly suitable for bending large-batch U-shaped flat steel, grooves with the width corresponding to the thickness of the flat steel to be bent are formed on the wheel die along the circumferential direction, grooves with the width corresponding to the thickness of the flat steel to be bent are formed on the clamping die and the sliding plate die along the linear direction, the groove structure is used for clamping the flat steel to be bent after being closed, after being clamped, the air cylinder drives the sliding plate die to rotate around the rotating shaft of the wheel die, the air cylinder jacks up the sliding plate die to bend the flat steel in the process of turning the sliding plate die by 90 degrees, after the steel sheet is bent, the lower clamping die is driven by the air cylinder to move downwards, and the bent flat steel is taken out. The device for one-step forming of the flat steel has the advantages that the device for one-step forming of the flat steel is accurate in size positioning, the formed flat steel conforms to the product use, the labor cost is reduced, the product appearance is improved, the machining efficiency is improved, the universality of the device is good, and the use requirement is met.

The utility model has the advantages that:

the utility model has the advantages of reasonable design, its volume carries out two curved one shot forming to the band steel, and the size location is accurate, and the planogramming accords with the product and uses after the shaping, reduces the cost of labor, improves the product appearance, improves machining efficiency, and the commonality of device is good.
