The following description will be made with reference to the accompanying drawings, but the present invention is not limited thereto.
Fig. 1 and 2 show a double-pressurization type powerful press with a lifting platform, which comprises an upper press 1, a lower press 2, guide pillars 3, a lifting platform 4, buffer oil cylinders 5, a movable base 6 and a force-bearing fixed mold 7, wherein the guide pillars 3 are respectively arranged at four corners of the lower press 2 and correspondingly connected with the upper press 1, the guide pillars 3 sequentially penetrate through the upper press from top to bottom and are in sliding connection with the lifting platform 4 and the movable base 6, the bases of the buffer oil cylinders 5 are symmetrically arranged at two sides of the upper press 1, movable push rods of the buffer oil cylinders are respectively connected with and drive the lifting platform 4 to slide up and down along the guide pillars 3, the force-bearing fixed mold 7 is arranged under the lifting platform 4 and is fixedly connected with the movable base 6, and the movable base 6 is connected with the lower press 2 and is driven by the lower press.
In order to buffer the impact force of the upper press 1 and reduce the impact vibration, as an improvement of the invention, the upper press 1 comprises an upper main oil cylinder 11 and an upper auxiliary oil cylinder 12, and the upper auxiliary oil cylinder 12 is diagonally arranged at two sides of the upper main oil cylinder 11.
In order to buffer the impact force of the lower press 2 and reduce the impact vibration, as an improvement of the present invention, the lower press 2 includes a lower main cylinder 21 and an upper sub cylinder 22, and the upper sub cylinder 22 is diagonally disposed on both sides of the upper main cylinder 21.
In order to accurately control the moving distance of the upper main oil cylinder 11, as a modification of the present invention, the present invention further comprises a first stroke sensor 8, and the first stroke sensor 8 is installed on the upper portion of the guide post 3 corresponding to the upper main oil cylinder 11.
In order to accurately control the moving distance of the lower main oil cylinder 21, as a modification of the present invention, a second stroke sensor 9 is further included, and the second stroke sensor 9 is installed at a lower portion of the guide post 3 corresponding to the lower main oil cylinder 21.
In order to accurately control the moving distance of the buffer cylinder 5, as a modification of the present invention, a third stroke sensor 10 is further included, and the third stroke sensor 10 is installed at the upper portion of the guide pillar 3 corresponding to the buffer cylinder 5.
The working principle of the invention is as follows: as shown in fig. 3, an upper die 100 is fixedly mounted on an upper main oil cylinder 11 and driven by the upper main oil cylinder 11, a lower die 200 is fixedly mounted on a lifting platform 4, when the upper die enters a working state, a lower main oil cylinder 21 of a lower press 2 starts to push a movable base 6 upwards and is propped against the lifting platform 4 by a force-bearing fixed die 7 fixed on the movable base 6 to rise to a set height together, a material distributor fills the material into the lower die and then withdraws from a working surface, when the upper main oil cylinder 11 of the upper press 1 starts to descend to contact the material, the upper main oil cylinder 11 and the lower main oil cylinder 21 pressurize and compact the material, after compacting the material, the lower main oil cylinder 21 retracts downwards, the upper main oil cylinder 11 continues to move downwards and pressurize, the lifting platform 4 accelerates to move downwards, at the moment, an upward force of a buffer oil cylinder 5 plays a role in buffering the lifting platform 4, the product forming stamping time is prolonged, and enough time is given, effectively reduces the defects of the interlayer inside the product caused by the fact that small parts of residual bubbles cannot be released and discharged in time due to the rapid combination of the upper and lower structure layers inside the product formed by the upper and lower pressing machines. When the lifting platform 4 descends to a set height, the upper main oil cylinder 11 stops pressurizing and moves downwards and retracts upwards to the initial position, after a product is taken out, the lower main oil cylinder 21 of the lower press 2 starts to push the movable base 6 upwards and the lifting platform 4 is jacked by the fixed bearing mould 7 fixed on the movable base 6 to ascend to the set height together to perform the cloth stamping process of the next period, and the process is repeated.
