Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic presses, and specifically to a six-station fully automatic servo hydraulic press. Background Art

[0002] Currently, in the process of industrial production and processing, it is inevitable to use hydraulic presses. Sometimes, in order to ensure sufficient hydraulic power or to be able to supply a sufficient number of pressing stations simultaneously, it is necessary to install multiple hydraulic cylinders on the hydraulic press to achieve linkage control. However, in the existing hydraulic press structures, multiple hydraulic cylinders are mostly installed separately, so when combined and connected inside the hydraulic press, it is easy to cause a large installation position error, affecting the balance during pushing. At the same time, it is necessary to connect multiple pipelines separately for control, resulting in complex pipelines and poor usage effects. And most servo hydraulic presses have one stamping slider corresponding to one stamping oil cylinder, and several stamping oil cylinders are installed corresponding to the number of stations. This leads to the overall pressing accuracy of the integrated hydraulic press not being uniformly controlled, and processing errors often occur. Moreover, most traditional stamping assemblies use four hydraulic thin columns to follow up and down. Although the lifting speed is fast, the pressing accuracy cannot be guaranteed, and it is even more impossible to control the pressing accuracy of each stamping slider at multiple stations. And as the usage time extends, it is easy to generate noise inside the hydraulic press, which will affect the normal use of the pressing workshop. Summary of the Invention

[0014] The present invention provides a six-station full-automatic servo hydraulic press, which has the following beneficial effects:

[0015] First, this six-station full-automatic servo hydraulic press adopts the principle of reflection. By setting the combined use of the chamfered portion and the annular groove, the sound wave is reflected inside the second-order cylinder to generate a phase cancellation, reducing the generation of noise, effectively reducing the output of noise, and causing the sound wave to disappear during propagation.

[0016] Second, this six-station full-automatic servo hydraulic press adds some elastic materials, such as rubber, to the annular corner cavity and the annular groove inside the second-order cylinder. Such elastic materials can absorb the vibration during transmission and reduce the generation of noise. When the original sound is transmitted through the second-order cylinder, the elastic material exhibits a damping effect to prevent the spread of noise and achieve the effects of vibration damping and noise reduction.

[0017] Third, this six-station full-automatic servo hydraulic press assembles the second-order plate member on the first-order plate member, then assembles the third-order plate member on the second-order plate member, and finally drives the third-order plate member to move up and down separately through the servo electric oil cylinder to avoid the precision error caused when multiple oil cylinders drive the stamping assembly to operate separately, and improve the pressing precision of the hydraulic press.

[0018] IV. For this six-station full-automatic servo hydraulic press, by replacing two hydraulic thin columns in a set of diagonals in the traditional stamping assembly with screws, the threaded installation method of screwing the screws to the bottom of the housing, the inner side of the built-in shaft cylinder, and the inner side of the built-in shaft ring can be used. Under the downward guidance of the hydraulic thin columns installed in the other set of diagonals, the screws are driven to move up and down regularly in a threaded and gentle manner to restrain the up and down movement of the hydraulic thin columns, promote the stable lifting of the hydraulic thin columns, realize the slow downward movement of the stamping assembly and the slow pressing action, improve the production accuracy, and avoid the shaking of the local structure of the stamping assembly and the processing error of the workpiece.

[0019] V. For this six-station full-automatic servo hydraulic press, by filling sound-absorbing cotton, fiberglass, knitted cotton and other materials inside the annular corner cavity, the ring slot and the arc cavity, and using the fact that these materials can effectively absorb sound and convert sound waves into other forms of energy such as heat energy. When the sound waves enter the second-order cylinder, they will continuously bounce in the materials until they are completely absorbed, realizing the absorption and elimination of the sound generated by the screws after long-term work with the threads or the inner side of the built-in shaft cylinder in the second-order cylinder, realizing the noise reduction and silencing function of the hydraulic press, and eliminating the hidden danger that the mechanical friction sound between the structures becomes louder after long-term use.

The top of the screw rod 54 threadedly passes through the housing 41, the inner shaft cylinder 426 and the inner shaft ring 84, and is threadedly installed with these three.

[0038] Adopting the principle of reflection, through the combined use of the chamfered portion 87 and the ring groove 83, the sound wave is reflected inside the second-order cylinder 81 to generate a canceling phase, reducing the generation of noise, effectively reducing the output of noise, and making the sound wave disappear during propagation.

[0039] Some elastic materials, such as rubber, can be added to the annular corner cavity 82 and the ring groove 83 inside the second-order cylinder 81. Such elastic materials can absorb the vibration during transmission and reduce the generation of noise. When the original sound is transmitted through the second-order cylinder 81, the elastic material exhibits a damping effect to prevent the propagation of noise, achieving the effects of vibration damping and noise reduction.

[0040] The second-order plate member 44 is assembled on the first-order plate member 43, and then the third-order plate member 45 is assembled on the second-order plate member 44. Finally, the third-order plate member 45 is driven to move up and down separately by the servo electric oil cylinder 7 to avoid the precision error caused by multiple oil cylinders driving the stamping assembly 5 to operate separately, and improve the pressing precision of the hydraulic press.

[0041] Second embodiment, on the basis of the first embodiment, please refer to Figure 2 and Figure 3As shown in the figure, six stamping assemblies 5 are linearly arrayed and installed at the bottom of the housing 41. The stamping assembly 5 includes a stamping slider 51. In the middle of the top end of the stamping slider 51, a main upper oil cylinder 52 is connected. At a set of diagonal corners at the top end of the stamping slider 51, hydraulic thin columns 53 are connected. At the other set of diagonal corners, a screw rod 54 is installed. And at the position where the screw rod 54 extends into the stamping slider 51, a ring plate body 55 is fixedly installed. The screw rod 54 is rotatably installed with the stamping slider 51 through the ring plate body 55. The top of the main upper oil cylinder 52 penetrates through the housing 41 and sequentially passes through the large ring sleeve 421, the cover cylinder 445 and the main cylinder sleeve plate 442, and is arranged at the top of the main cylinder sleeve plate 442. The top of the hydraulic thin column 53 penetrates through the housing 41 and sequentially passes through the thin column guide sleeve 423 and the small stirrup 432, and extends out of the top of the small stirrup 432.

[0042] By replacing two hydraulic thin columns 53 in a set of diagonals in the traditional stamping assembly 5 with screw rods 54, the threaded installation method in which the screw rods 54 are threadedly connected to the bottom of the housing 41, the inner side of the built-in shaft cylinder 426, and the built-in shaft ring 84 can be utilized. Under the downward pressure guidance of the hydraulic thin columns 53 installed at the other set of diagonals, the screw rods 54 are driven to move gently up and down in a regular threaded manner, so as to restrain the up and down movement of the hydraulic thin columns 53, promote the stable up and down movement of the hydraulic thin columns 53, and realize the slow downward movement and slow pressing action of the stamping assembly 5. Improve the production accuracy and avoid the shaking of the local structure of the stamping assembly 5 and the machining error of the workpiece.

[0043] It is also possible to fill sound-absorbing cotton, fiberglass, knitted cotton and other materials inside the annular corner cavity 82, the annular groove 83 and the arc cavity 86. By using these materials, they can effectively absorb sound and convert sound waves into other forms of energy such as heat energy. When sound waves enter the second-order cylinder 81, they will continuously bounce in the materials until they are completely absorbed, realizing the absorption and elimination of the sound generated by the screw rod 54 after long-term work with the built-in shaft ring 84 or the built-in shaft cylinder 426 in the second-order cylinder 81, realizing the noise reduction and sound elimination function of the hydraulic press, and eliminating the hidden danger that the mechanical friction sound between structures becomes louder after long-term use.

[0044] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative work shall fall within the protection scope of the present invention.
