Abstract
The utility model relates to a shallow corrugated metal sheet hydraulic machine which comprises an upper beam and a lower beam of a rack, a pressure workbench, four stroke cylinders and sliding blocks connected with the stroke cylinders. The shallow corrugated metal sheet hydraulic machine is characterized in that a pressure operating cylinder is arranged below the workbench, the pressure operating cylinder comprises a cylinder body base plate and a pressure plunger, and the pressure plunger is in contact with the lower surface of the workbench; fixed pressure blocks are fixed on the inner end face of the upper beam, sliding block pressure blocks are arranged on the upper surfaces of the sliding blocks, the sliding block pressure blocks and the fixed pressure blocks are arranged in a staggered and fitted mode, and cushion blocks of the sliding block pressure blocks are meshed with or abut against the fixed pressure blocks after being moved in a parallel mode under the action of a push-and-pull cylinder. The shallow corrugated metal sheet hydraulic machine has the advantages that due to the fact that the short-stroke operating cylinder and the large-stroke stroke cylinders replace large-stroke operating cylinders, the structure of the operating cylinder is simplified, the size and weight of the operating cylinder are reduced, no liquid-filling process exists when the operating cylinder approaches the workbench quickly, and the stroke cylinder carries out the liquid-filling process.
Description
Technical field
The utility model belongs to hydraulic press, relates in particular to a kind of shallow corrugated metal sheet hydraulic press.
Background technology
Shallow corrugated metal sheet hydraulic press is used for the moulding of the shallow stretching of high density ripple and nonmetal plate, as plate-type heat exchanger slab, hydrogen manufacturing electrode plate and carborundum plate etc.Plate type heat exchanger is suppressed with metal sheet, exigent specific pressure (500-600bar), the total pressure of equipment is just higher, the press tonnage that the plate that size differs larger requires differs also larger, therefore usually may select between 3000t-20000t, be to waste energy with large press compacting platelet template sheet one, the 2nd, and inconvenient operation, therefore for middle-size and small-size factory except large press is arranged, also to configure small-sized press.Yet large press frequency of utilization is often idle, very uneconomical far below small hydraulic machine.
The metal sheet hydraulic press,, especially for the hydraulic press of high density ripple, adopt the super-pressure fuel feeding, and its oil cylinder pressure used is very high.Send into, send space due to what pressing process needed plate, so the stroke of stroke oil cylinder is far longer than the stroke of operating cylinder.In addition,, because the wall thickness of oil cylinder is larger, make the centre-to-centre spacing lengthening of two oil cylinders, in the middle of two cylinders, capped part is also just larger, causes the plate of compacting middle under-voltage, causes the Forming Quality of sheet material unstable.
The metal sheet of shallow corrugated such as plate-type heat exchanger slab moulding need very high pressure, when the plate that compacting is grown, need to adopt two master cylinders by workbench, plate in mould to be exerted pressure, because oil pressure in master cylinder is very high, therefore the cylinder barrel wall thickness is very thick, causes between two plungers spacing very large, and this spacing is exactly the low pressure zone that by plunger, is not covered, will produce under-voltage in the middle of the plate that this low-pressure is depressed is that ripple's depth does not reach the situation that regulation requires, and makes the compacting Quality Down.
In addition, due to input and output material and dress mould to the requirement in space, the total travel (〉 250mm of master cylinder) be far longer than pressing stroke (＜10mm), this not only makes machine dimensions strengthen, during more due to pressurization, in oil cylinder, oil pressure contracting required time and energy descend compacting efficiency and energy utilization rate greatly.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of shallow corrugated metal sheet hydraulic press is provided, upper underbeam pressurization by frame, shortened the centre-to-centre spacing of twin-tub, dwindle pressurized operation platform middle part not by the oil cylinder overlay area, the middle part that more is conducive to workpiece is shaped, and avoids suppressing the generation of the middle under-voltage quality problems of plate.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of shallow corrugated metal sheet hydraulic press, comprise underbeam on frame, pressurized operation platform, four stroke oil cylinders and coupled slide block, it is characterized in that: described workbench below is provided with the pressurized operation oil cylinder, described pressurized operation oil cylinder comprises cylinder body backing plate and pressure plunger, and described pressure plunger and workbench lower surface touch; The inner face of described upper beam is fixed with fixedly pressure block, described slide block upper surface is provided with the slide block pressure block, described slide block pressure block and the fixedly staggered inserted type setting of pressure block, the cushion block of described slide block pressure block are nibbled with fixing pressure block after by the push cylinder parallel or top mutually mutually.
Described slide block pressure block is linked to be an integral body by side plate and does the reciprocating motion of a slide block pressure block width under the push cylinder effect, thereby realizes and the nibbling mutually or pushing up mutually of fixed support block; Described push cylinder or be contained in upper beam, promote the fixedly pressure block that is connected with upper beam.
Between the hole wall on described pressurized operation Cylinder Plunger and cylinder body backing plate, sealing ring is housed, described cylinder body backing plate is placed in the framework lower position, is equipped with the pressurized operation platform on the cylinder body backing plate, and the pressurized operation platform is connected with slide block by four groups of guide pillar guide pin bushings.
Described pressurized operation oil cylinder quantity is 1-2.
Beneficial effect: replace the working cylinder of large stroke with the stroke oil cylinder of the operating cylinder of short stroke and large stroke, not only can simplify the working cylinder structure, reduce volume weight, and when need not the topping up process during fast approaching between workbench, and by stroke oil cylinder, carried out.For the double-cylinder structure hydraulic press, can significantly shorten centre-to-centre spacing, reduce pressurized operation platform middle part not by the oil cylinder overlay area, more be conducive to the middle part moulding of workpiece.
