As shown in FIG. 1, the shaping device of the marine energy absorber comprises a top die 1, an upper die 3, a middle die 5, a pull rod 6 and a lower die 8. The outer tube 4 of the energy absorber is an outer fixing device of the energy absorber, the inner tube 2 of the energy absorber is an inner fixing device of the energy absorber, and the rubber piece 7 is an inner rubber filler of the energy absorber.
Specifically, the rubber member 7 is wound around the outer surface of the inner tube 2, and the outer surface of the rubber member 7 is fixed to the inner surface of the outer tube 4 in a contact manner, and the outer surface is fixed in an adhesive manner. The lower end face of the outer tube 4 of the energy absorber is contacted with the upper end face of the upper die flange of the lower die 8, the inner surface of the outer tube 4 of the energy absorber is axially fixed with the round center core of the lower die 8, and the upper end face of the outer tube 4 of the energy absorber is contacted with the lower end face of the upper die 3.

And then the energy absorber outer tube 4 is arranged, and after positioning, the energy absorber outer tube 4 and the lower die 8 are integrally arranged on the lower die 8, so that the energy absorber outer tube 4 and the lower die 8 are ensured to be in contact with the ground in the axial direction.

And the upper die 3 is assembled, and the lower end of the upper die 3 is completely contacted with the upper end face of the middle die 5. And finally, directly compacting the top die 1 through end surface contact.

Specifically, the filler design process:
and (3) carrying out corresponding mechanical property tests under the condition that the formed size of the ship energy absorber meets the requirement, and generating upper nonmetallic cracks or fractures. As shown in fig. 1, the analysis shows that in the vulcanization process, as the temperature increases, the metal at the a part is conductive to heat, the air at the B part is conductive to heat, the metal and the air are different in coefficient of heat conductivity, the coefficient of heat conductivity of the metal is far greater than that of the air, the heat conduction quantity at the a part is far greater than that at the B part, more heat is received at the a part than at the B part in the same time, the performance parameters of the rubber after vulcanization at the a part and the B part are different, and finally cracks and fractures appear at the a part. The above parts were subjected to a split test, and the performance indexes of the metal direct contact and air contact parts were different, specifically, the performance test data table after the split was not filled in table 1.
| A is | B part | |
| Hardness (Shore A) | 70 | 65 |
| Tensile Strength (MPa) | 17 | 21 |
| Elongation at break (%) | 190 | 250 |
TABLE 1
From the above analysis and data, it was confirmed that the difference in structure between the a and B positions resulted in uneven heating of the two positions, and eventually resulted in inconsistent rubber properties, and cracking and breaking occurred during stretching. Moreover, the analysis suggests that reversion of the rubber is also likely to occur if the temperature or time changes A.
According to the above technical drawbacks, as shown in fig. 1, four kinds of fillers are formulated between the outer tube 4 and the middle die 5 of the energy absorber: water, quartz sand, iron sand, and stainless steel sand. The filling material is used for filling, four test pieces are respectively subjected to mould pressing again, then the tensile test is carried out on the products, the appearance can meet the use requirements, and no crack and fracture phenomenon occur. The four test pieces were tested for a split check at positions a and B and the test data are shown in table 2 with the addition of a filler split performance test data table.
TABLE 2
Data comparison and analysis are carried out:
as can be seen from the comparison of the test data, the performance of the rubber is improved, the tensile strength at the A position is improved by 20%, the hardness is improved by more than 5%, and the elongation at break is improved by more than 20%, wherein the test data A and B positions of the iron sand and the stainless steel sand are in the most fit.
The coefficient of heat conductivity of water is slightly lower than that of metal, the tightness of water used as a filler is not well controlled, if water leaks out, the outer surface of a product is easy to rust, a substrate is corroded, and the use requirement cannot be met. The specific heat capacity of water is larger, local overheating is easy to occur, uneven heating of products occurs, and the rubber performance parameters of the processed products are uneven, even the local performance is unqualified. The test data are also less than ideal for hardness and tensile strength, so water cannot be used as a filler.
The quartz sand has low relative strength and is fragile, and is easy to harden after being used for a period of time, so that the quartz sand needs to be backwashed. When the back flushing strength is too high, fine particles of quartz sand can be carried out, so that the loss of the quartz sand is caused. When the back flushing strength is too small, the quartz sand with a larger lower part cannot be loosened. If the quartz sand is kept for a long time, the quartz sand is easy to harden and is mixed with foreign matters. The quartz sand is formed by crushing and processing quartz stone, has larger primary thermal expansion coefficient, lower thermal diffusivity and lower heat storage coefficient, and is easy to react with the interface of metal to have adverse effect. The quartz sand dust is relatively large, and the long-term inhalation of operators in the sand cleaning process easily affects the physical health of people. In the test data, the hardness at the position A is slightly low and the tensile deformation rate is larger, so that quartz sand cannot be used as a filler.
The iron sand metal is easy to rust and corrode, and is unfavorable for use and preservation. The iron sand has high conductivity, is easy to cause local overheating, and affects the performance index of the product. Iron sand is unfavorable for water washing, has large dust, is easy to inhale in long-term operation to affect the physical health of people, and although the data can meet the technical index requirements, the use and the operation are unfavorable for the long-term development of enterprises, so the iron sand cannot be used as a filler.
Stainless steel sand is angular particles made of stainless steel, stainless steel water is refined by an electric furnace, round particles are obtained through atomization and granulation, irregular angular particles are formed through crushing, and then the stainless steel sand is finally obtained through granularity screening and heat treatment. The stainless steel sand is not easy to break, the service life is long, the consumption is lower, and the consumption cost can be reduced. Meanwhile, the dust emission is less, and the occupational health hazard is reduced. The stainless steel sand has high strength, precise and pure components and easy cleaning, so that the stainless steel sand has longer service life and saves cost. And the stainless steel sand has low specific heat and high conductivity, so that the product can be heated uniformly, and the yield of the product is improved.
The actual measurement data can also well meet the product performance requirements, and the actual measurement data from theory and experiment can meet the requirements, thereby being more beneficial to saving cost and long-term development of enterprises, and in conclusion, the decision is made to adopt stainless steel sand as the filler between the outer surface and the middle die of the energy absorber.
The improved design of the shaping device of the marine energy absorber can effectively finish the shaping design of various large marine energy absorbers, improve the yield and increase the enterprise efficiency, and the system has novel design, economy and applicability.
The above-described embodiments are merely preferred embodiments for fully explaining the present utility model, and the scope of the present utility model is not limited thereto. Equivalent substitutions and modifications will occur to those skilled in the art based on the present utility model, and are intended to be within the scope of the present utility model.
