Embodiment 1
As shown in Figures 3 to 6, a kind of reinforcement press for unicast waveform plate die moulded, including rack, moved cross beam 2, plus
Press mechanism and a kind of reinforcement press die.
Rack includes the pedestal 11, column 13, upper beam 12 fixed on the ground, and 13 one end of column is fixed on pedestal 11
On, 13 other end of column and upper beam 12 are fixed, and usual column 13, pedestal 11, upper beam 12 form the frame of a cuboid
Structure, when press pressurization, rack provides reaction force, forms reaction frame.
Moved cross beam 2 is mounted between upper beam 12 and pedestal 11, can be moved up and down along column 13.
Pressing mechanism uses hydraulic cylinder, has many advantages, such as that pressure is big, it is steady to move, hydraulic cylinder include cylinder body, piston,
Connecting rod.Pressing mechanism includes level-one oil cylinder 31 and two-level oil cylinder 32, and the cylinder body of level-one oil cylinder 31 is fixed on the downside of upper beam 12,
It is fixedly connected on the upside of the connecting rod lower end of level-one oil cylinder 31 and moved cross beam 2.Two-level oil cylinder 32 is arranged in below moved cross beam 2, and two
The cylinder body of grade oil cylinder 32 is fixed on moved cross beam 2, and when two-level oil cylinder 32 pressurizes, two-level oil cylinder's connecting rod can be with respect to moved cross beam 2
It moves down.
Mold includes lower mold 41 and upper mold 42, and upper mold and lower mold 41 are mutually matched, and lower mold 41 is fixed on bottom
On seat, upper mold 42 includes the first upper mold section 421 and the second upper mold section 422.First upper mold section 421 is fixed on movable transverse
The lower middle side part of beam 2, two-level oil cylinder 32 are arranged in 421 outside of the first upper mold section, and the second upper mold section 422 is connected to two-level oil cylinder
The movable end of 32 connecting rods.
When two-level oil cylinder 32 pressurizes, the second upper mold section 422 is moved down with the connecting rod of two-level oil cylinder 32, to the two of workpiece 5
Side carries out swaging, first presses and presses two sides again in the middle part of workpiece, small to the physical damnification of steel plate, overcomes conventional moulded method upper mold at present
Pressure, the defect that two sides steel plate is unable to free extension, corner metal phase slides.
The reinforcement press die of the present embodiment is commonly used in the compacting of the corrugated sheet steel of single waveform, specific pressure forming
Process is as follows:
S1: first workpiece 5 is placed between upper mold 42 and lower mold 41；
S2: starting press machine, level-one oil cylinder 31 load, and the piston driving connecting rod of level-one oil cylinder 31 moves down, and drive movable transverse
Beam 2 and the synchronous pushing of the first upper mold section 421, the first 421 pairs of upper mold section workpiece middle part carry out swaging；Two-level oil cylinder at this time
32 do not pressurize, and two-level oil cylinder 32 moves synchronously with moved cross beam 2, when moved cross beam 2 reaches range d1, the second upper mold
Having the distance between section 422 and lower mold 421 is d2, and d2 need to be greater than the distance that steel plate two sides upwarp when being molded in the middle part of steel plate, with
Two sides steel plate upwarps and will not damage the second upper mold section 422 when die mould in the middle part of guarantee steel plate；
S3: when press machine is loaded into rated pressure, press machine load stops, to progress pressure maintaining in the middle part of steel plate；
S4: the carry out partial pressure unloading to level-one oil cylinder 31, residual compression can work as second by Interal fixation, with guarantee
In lower mould upstream movement, which occurs, for steel plate when upper mold section 422 pushes is advisable, and usual residual compression is that level-one oil cylinder is full when loading
The 1%~50% of volume pressure；Upper mold sections at different levels are also equipped with varistor, for measuring pressure of the oil cylinders at different levels in swaging
Power；
S5: starting two-level oil cylinder 32 is loaded, and the piston rod of two-level oil cylinder 32 moves down, and drives the second upper mold section
422 push, and carry out swaging to the two sides of workpiece 5；The sum of the pressure of multiple two-level oil cylinders 32 is not more than: press machine quota pressure-
Level-one oil cylinder residual compression.Assuming that the press machine of 1000 ton forces, when the first upper mold section 421 pushes, level-one oil cylinder 31 is loaded into
1000 ton forces, the residual compression after unloading for fixing workpiece is 100 ton forces, then the power of two-level oil cylinder 32 can reach 1000-100
=900 ton forces.
Existing press pressurizes to steel plate only with same group oil cylinder, that is, only has in the forming process of corrugated sheet steel
Level-one oil cylinder, force area is big when die mould.The prior art will such as improve press pressure, need to increase the pressure of level-one oil cylinder, apply
The active force being added on reaction frame increases, thus needs to improve the intensity of reaction frame, that is, increases the cost of reaction frame.This is practical new
Type uses boosting oil cylinder, and the middle part of first time laminated steel, second of laminated steel two sides reduces the area of each swaging, together
When each swaging pressure it is many there is no declining, first time swaging can reach quota pressure, second swaging two-level oil cylinder
Pressure can achieve the 99% of quota pressure, and the pressure of unit area nearly improves 1 times.
S6: when press machine is loaded into the rated pressure of two-level oil cylinder 32, stop load, pressure maintaining.
S7: the pressure of the first and second pressing mechanisms of release completes workpiece die mould.
Embodiment 2
Reinforcement press die shown in embodiment 2 includes multiple upper mold sections, as shown in the figure includes level Four, naturally it is also possible to
More.Such as Fig. 7, reinforcement press includes three-level oil cylinder 33 and level Four oil cylinder 34, and every grade of boosting oil cylinder is sequentially located at previous stage reinforcement
The outside of oil cylinder, correspondingly, the connecting rod lower end of every level-one two-level oil cylinder is fixedly connected with corresponding upper mold section, i.e. three-level oil cylinder 33
Third upper mold 423 is connected, level Four oil cylinder 34 connects the 4th upper mold 424.When die mould, oil cylinders at different levels drive outward from middle part
Each upper mold section successively pressurizes to workpiece, realizes the die mould of continuous wave.
Using multiple upper mold sections, have the advantage that
It is bigger relative to whole upper/lower die flexibility ratio, different swagings can be combined into according to multiple upper mold sections
Shape need to only repair or removable parts upper mold section when the damage of part upper mold section, reduce maintenance cost.
When carrying out swaging to workpiece, first presses in the middle part of workpiece and suppressed step by step to two sides again, overcome conventional moulded method upper mold simultaneously
It pushes, the defect that two sides steel plate is unable to free extension, corner metal phase slides, it is small to the physical damnification of steel plate.
The above is preferred embodiments of the present invention, is not departed from for those of ordinary skill in the art
Under the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model
Range.
