Abstract
A bidirectional pressing hydraulic machine comprises upper and lower hydraulic cylinders with the same tonnages, built-in upper and lower displacement sensors and upper and lower pressure sensors connected with upper and lower oil cylinders and a control system. Both the upper and lower hydraulic cylinders are connected with a synchronous flow distribution motor of a gear and is controlled by the synchronous flow distribution motor. The bidirectional pressing hydraulic machine realizes bidirectional synchronous pressing effect, is good in quality of products, does not cause harmful effect on a total system, and improves production efficiency and product percent of pass.
Description
Technical field
The utility model relates to a kind of bidirectional compression hydraulic press.
Background technology
Powder metallurgy adopts the unidirectional compression moulding of four-column hydraulic press usually, but owing to be subjected to press-fiting the restriction of thickness, the general density unevenness of finished product is even and cause finished product scrappage height, in order to guarantee the density of product, some producer is after suppressing one side, again product is turned, another side is press-fited, this method production efficiency undoubtedly is very low, and in the middle of the powder metallurgy product that has chip is arranged, like this, even turn compacting again, the position of chip also is difficult to assurance, thereby is difficult to guarantee the quality of product.
The utility model content
The utility model provides a kind of bidirectional compression hydraulic press, can effectively solve the product density inequality that traditional unidirectional compacting causes, the problem that defect rate is high.
For achieving the above object, by the following technical solutions:
A kind of bidirectional compression hydraulic press, the hydraulic cylinder that comprises upper and lower two equal tonnages, built-in upper and lower displacement sensor, and the upper and lower pressure sensor that links to each other with control system with upper and lower oil cylinder, described upper and lower hydraulic cylinder all links to each other with gear synchronized splitter motor and controlled by it.
As further improvement of the present utility model, reversal valve is in parallel with gear synchronized splitter motor, and be connected with upper and lower hydraulic cylinder.Before the compacting slide block of hydraulic cylinder touches dusty material, control its quick operation with common reversal valve, after touching dusty material, be changed to by the control of gear type synchronized splitter motor, improved operating efficiency and product quality.
The utility model adopts two outputs of gear type synchronized splitter motor to control upper and lower oil cylinder respectively, realized the synchronous of pressure and speed, before the compacting slide block of hydraulic cylinder touches dusty material, control its quick operation with common reversal valve, after touching dusty material, be changed to by the control of gear type synchronized splitter motor, improved operating efficiency and product quality.Upper and lower hydraulic cylinder is put inbuilt displacement sensor, detects the displacement constantly and the pressure of two cylinders constantly, and the synchronized splitter motor that leans on synchronously of displacement constantly of two cylinders and pressure is realized.The utility model has been realized the effect of bi-directional synchronization compacting, and product quality is intact, and can not produce harmful effect to whole system, has improved production efficiency and product percent of pass.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below:
Fig. 1 is the whole body structure schematic diagram of the utility model specific embodiment.
Among the figure:
1, top offset sensor; 2, go up hydraulic cylinder; 3, following hydraulic cylinder; 4, bottom offset sensor; 5, lower pressure sensor; 6, reversal valve; 7, gear type synchronized splitter motor; 8, upward pressure sensor; 9, control system.
The specific embodiment
As shown in Figure 1, provided a specific embodiment of the present utility model, among the figure, on last hydraulic cylinder 2 and the following hydraulic cylinder 3 top offset sensor 1 and bottom offset sensor 4 are housed respectively, and upward pressure sensor 8 and lower pressure sensor 5 are installed, upper and lower hydraulic cylinder all links to each other with gear synchronized splitter motor 7, reversal valve 6 all is installed on the motor output circuit, described displacement transducer 1,4, upper and lower pressure sensor 5,8 and gear type synchronized splitter motor 7 all link to each other with control system.Three reversal valves 6 are in parallel with gear type synchronized splitter motor 7, and are connected with upper and lower hydraulic cylinder 2,3.
Before the compacting slide block of hydraulic cylinder touches dusty material, move fast with common reversal valve 6 its hydraulic cylinders of control, after touching dusty material, be changed to by gear type synchronized splitter horse 7 and reach control, when increasing work efficiency, guaranteed the qualification rate of product.
