Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic stations for foaming furnaces, and in particular to a hydraulic station for foaming furnaces. Background Technology

[0002] A foaming furnace hydraulic station is a hydraulic system used in foaming furnace equipment. It mainly consists of a hydraulic oil tank, hydraulic pump, flow valve, hydraulic cylinder, etc. The hydraulic station converts hydraulic oil into mechanical energy through the working principle of the hydraulic system, driving the movement of various components of the foaming furnace and ensuring the normal operation of the foaming furnace.

[0003] The existing hydraulic system for embossing in a foaming furnace consists of a single circuit for the left and right cylinders, with the same pressure on both cylinders for embossing. The problem is that when the depth of the embossing is inconsistent on both sides, the pressure on the left and right sides needs to be adjusted, but the embossing cannot be changed by adjustment. Therefore, a new hydraulic station for foaming furnaces is needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic station for a foaming furnace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic station for a foaming furnace, comprising an oil tank workbench, a first connecting pipe fixedly connected to the side surface of the oil tank workbench, an oil pump fixedly connected to the end of the first connecting pipe away from the oil tank workbench, an oil outlet platform fixedly connected to the output end of the oil pump, a first oil outlet pipe and a second oil outlet pipe fixedly connected to the output end of the oil outlet platform, control valves fixedly connected inside the first oil outlet pipe and the end of the first oil outlet pipe threadedly connected to a second connecting pipe, and a flow valve fixedly connected inside the second connecting pipe, a third connecting pipe rotatably connected to the end of the second connecting pipe away from the first oil outlet pipe via a hose, a pressure gauge fixedly connected inside the third connecting pipe, a fourth connecting pipe threadedly connected to the end of the third connecting pipe away from the second connecting pipe, and a control valve also provided inside the fourth connecting pipe, a hydraulic cylinder fixedly connected to the end of the fourth connecting pipe away from the third connecting pipe, a fifth connecting pipe fixedly connected to the bottom of the hydraulic cylinder, and the end of the fifth connecting pipe away from the hydraulic cylinder fixedly connected to the interior of the oil tank workbench.

[0006] Furthermore: the control valve includes a valve body, the circumferential surface of which has an oil passage groove, the inner wall of which is fixedly connected to a fixing ring, and the inner wall of which is fixedly connected to a fixing strip and a limiting bracket.

[0007] Furthermore: a fixing post is fixedly connected inside the fixing strip, a slider is slidably connected to the circumferential surface of the fixing post, a slip ring is fixedly connected to the side surface of the slider, a stop block is fixedly connected to the side surface of the slip ring, and a stop ring is fixedly connected to the side surface of the stop block.

[0008] Furthermore, a spring is sleeved on the outside of the stop block, and the end of the spring is in contact with the side surface of the fixing ring, and the positions of the stop block and the fixing ring correspond to each other.

[0009] Furthermore: a connecting rod is rotatably connected to the top of the slider, a connecting column is rotatably connected to the end of the connecting rod away from the slider, and a handle is fixedly connected to the top of the connecting column.

[0010] Furthermore: a limiting block is fixedly connected to the circumferential surface of the connecting column, a limiting seat is fixedly connected to the top of the valve body, a limiting hole is opened on the top of the limiting seat, a limiting groove is opened inside the limiting seat, and the limiting groove is connected to the limiting hole, and the positions of the limiting block and the limiting hole correspond to each other.

[0011] This utility model has the following beneficial effects:

[0012] 1. Compared with the prior art, this foaming furnace hydraulic station, by setting a first oil outlet pipe, a second oil outlet pipe, a control valve, a second connecting pipe, and a third connecting pipe, divides the oil circuit into two parts through the first and second oil outlet pipes during use. When the flow valve and pressure gauge need to be repaired or replaced, it is only necessary to close the control valves on both sides at the same time. This makes it easy to remove the second and third connecting pipes from the first and fourth oil outlet pipes for repair, which improves the convenience of device maintenance. Moreover, when the first oil outlet pipe is closed, the second oil outlet pipe can be used to continue working, avoiding any impact on the use of the foaming furnace hydraulic station.

[0013] 2. Compared with the prior art, this foaming furnace hydraulic station, by setting up a slider, slip ring, stop block and spring, allows the connecting column to rotate through the limit hole and inside the limit groove when the handle is pushed down during use. This limit groove limits the connecting column. When the connecting column moves down, it pushes the slider and slip ring through the connecting rod, thereby compressing the spring and causing the stop block to extend inside the fixed ring until the stop ring engages with the inside of the limit frame, thus closing the valve body. When opening, rotating the handle allows the stop block to be indirectly removed from inside the fixed ring through the connecting column, thus opening the valve body. This improves the practicality of the device. Attached Figure Description

The bottom of the hydraulic cylinder 13 is fixedly connected to the fifth connecting pipe 14, and the end of the fifth connecting pipe 14 away from the hydraulic cylinder 13 is fixedly connected to the inside of the oil tank workbench 1. When the device is in use, the oil circuit is divided into two parts through the first oil outlet pipe 5 and the second oil outlet pipe 6. When the flow valve 9 and the pressure gauge 11 need to be repaired or replaced, it is only necessary to close the control valve 7 on both sides at the same time. This makes it easy to remove the second connecting pipe 8 and the third connecting pipe 10 from the first oil outlet pipe 5 and the fourth connecting pipe 12 for repair, which improves the convenience of device maintenance. Moreover, when the first oil outlet pipe 5 is closed, the second oil outlet pipe 6 can be used to continue working, avoiding any impact on the use of the foaming furnace hydraulic station.

[0024] The control valve 7 includes a valve body 701. An oil passage groove 702 is formed on the circumferential surface of the valve body 701. A retaining ring 703 is fixedly connected to the inner wall of the oil passage groove 702. A retaining strip 704 and a limiting bracket 705 are fixedly connected to the inner wall of the retaining ring 703. The oil passage groove 702 runs through the interior of the valve body 701, facilitating the installation of other parts inside the oil passage groove 702.

[0025] A fixing post 706 is fixedly connected internally to the fixing strip 704. A slider 707 is slidably connected to the circumferential surface of the fixing post 706. A slip ring 715 is fixedly connected to the side surface of the slider 707. A stop block 716 is fixedly connected to the side surface of the slip ring 715. A retaining ring 717 is fixedly connected to the side surface of the stop block 716. The slider 707 and the slip ring 715 are slidably connected externally to the fixing post 706, and the slip ring 715 facilitates the displacement of the stop block 716 and the retaining ring 717.

When the connecting column 709 moves downward, the limiting block 713 passes through the limiting hole 711 and rotates into the limiting groove 712, thereby limiting the movement of the connecting column 709.

[0029] Working principle: When the device is in use, the oil circuit is divided into two parts through the first oil outlet pipe 5 and the second oil outlet pipe 6. When the flow valve 9 and the pressure gauge 11 need to be repaired or replaced, it is only necessary to close the control valve 7 on both sides at the same time. This makes it easy to remove the second connecting pipe 8 and the third connecting pipe 10 from the first oil outlet pipe 5 and the fourth connecting pipe 12 for repair, which improves the convenience of device maintenance. Moreover, when the first oil outlet pipe 5 is closed, the second oil outlet pipe 6 can be used to continue working, avoiding any impact on the use of the foaming furnace hydraulic station.
