Abstract
The invention relates to a device which can provide different pressure-pad-forces according to different deformation areas in the process of the calendaring of a large and medium-size covering piece. The device covers a layer of flake type holding pads on a traditional pressure-pad-ring. Oil cylinders with adjustable pressure are supported under each piece of holding pad. Various pressure-pad-forces are generated through adjusting the pressure of the oil inlet of each oil cylinder, which leads the calendaring process to be smoothly realized.
Description
Affiliated technical field
The invention belongs to the cold stamping shaped technical field of thin plate, is the indispensable device of big-and-middle-sized thin plate calendering mould.
Background technology
Based on the theory and practice of thin plate calendering technology, big-and-middle-sized thin plate usually can take place wrinkling in the calendering formation process, breaks, and warpage etc. influence the carrying out of calender line and the normal delivery of inter process.The blank holder that traditional calendering mould is used (seeing accompanying drawing 1) relies on die trial repeatedly to come the blank holder processing of making amendment is wasted time and energy, and often do not reached perfect condition fully.
Summary of the invention
The verified stress state of reasonably controlling thin plate flanging zone slab interior in calender line of theory analysis and practice can effectively be controlled wrinklingly, breaks and calendering forming defect such as warpage.For this reason, at of the different stress requirements of each deformed region of covering to the flanging zone, traditional blank holder reasonably is divided into several isolated areas, and each zone applied different pressure-pad-forces, make the stress state of slab interior in flanging zone more help rationally carrying out of calender line.
The pressure-pad-force of each isolated area is to be provided by lathe air cushion and the controlled hydraulic jack of pressure, according to on-the-spot die trial situation, reasonably adjusts the input pressure of each oil cylinder by oil supply system and both can realize the pressure-pad-force of zones of different is controlled (seeing accompanying drawing 2).
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is the structure chart of traditional covering blank holder.
Accompanying drawing 2 is structure charts of scaly-type pressure-adjustable covering part blank holder device of the present invention.
Among Fig. 1,1. blank holder, 2. binder pressure pin, 3. holding pad, 4. binder muscle groove, 5. die hole.
Among Fig. 2,1. blank holder scale, 2. whole bearing, 3. power transmission push rod, 4. oil cylinder piston bar, 5. oil cylinder, 6. binder pressure pin, 7. adjustable pressure oil inlet, 8. die hole of blank holder.
The specific embodiment
Reasonable division to the flanging zone need have certain practical experience, and generally speaking, the deformed area of covering can be divided into the pull and stretch district approx, bulging district, simple deformed region such as buckled zone and transition region.Different types of deformed region has different requirements to the pressure-pad-force in its flanging zone.
In Fig. 2, to locate to contact in die hole (8) in die, the plate decline process with blank holder scale (1), binder pressure pin (6) is used for supporting die, plate and blank holder scale (1).Plate is when being subjected to punch effect distortion, the whole bearing of blank holder (2) is along with die moves downward, power transmission push rod (3) descends thereupon and contacts with oil cylinder piston bar (4), hydraulic oil in the oil cylinder (5) is by adjustable pressure oil inlet (7) turnover oil cylinder (5), regulate the distance that moves up and down of oil cylinder piston bar (4), be applied to the clamping force that plate bears between blank holder scale (1) and the die thereby change.Blank holder scale (1) distributes on every side ringwise in die hole (8), and size and shape all can not wait, should be according to the thrust calculating that each region area bore.
Claims (3)
1. adjustable blank holder device of flake type pressure-pad-force, separate continuous multi-disc holding pad covers on the blank holder bearing, every holding pad provides pressure by independent adjustable in pressure oil cylinder, and the blank holder bearing provides pressure by the lathe air cushion, thereby constitutes the complete flexible flange fixing installation of a cover.It is characterized in that every holding pad provides pressure-pad-force separately, the multi-disc holding pad constitutes the adjustable flange fixing installation of pliable pressure continuously.
2. the adjustable blank holder device of flake type pressure-pad-force according to claim 1 is characterized in that: the device that holding pad pressure is provided can be an oil cylinder, also can be other device or elements that power can be provided.
3. according to claim 1, the adjustable blank holder device of 2 described flake type pressure-pad-forces, it is characterized in that: the pressure that the blank holder bearing is provided can be the lathe air cushion, also can be other elastic device or element.
