Description

Combined plate hydraulic press

technical field

The utility model belongs to a hydraulic press, in particular to a combined plate hydraulic press used for shallow stretching of thin plates.

Background technique

At present, the hydraulic presses used for plate pressing of plate heat exchangers are all special mechanical equipment. Usually, large-scale hydraulic presses are used to press large-area sheets, and small-scale hydraulic presses are used to press small-area sheets. When a factory with a large hydraulic press accepts an order for pressing a small plate, because the table of the large hydraulic press is too long, sometimes it cannot be operated or the small plate is not easy to feed. If the discharging position is inaccurate, it will cause waste products, so using a large hydraulic press to press small plates not only causes energy waste, but also has low efficiency and is unsafe. Therefore, most factories need to configure one or two small hydraulic presses to only accept orders for processing small plates, or purchase a large and a small hydraulic press to meet market demand. Since there is less demand for large-area plates in the market, and a large demand for small-area plates, the plan for the factory to purchase one large and one small hydraulic press will result in the idleness of large hydraulic presses. Of course, if you only buy a small hydraulic press, you cannot undertake the processing of large-area plates.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the above-mentioned technologies, and provide a combined plate hydraulic press that can not only press large plates but also satisfy the production of large quantities of small plates.

In order to achieve the above object, the utility model adopts the following technical solutions: a combined plate hydraulic press, including two load-bearing frames, the lower beam parts of the two load-bearing frames are fixed as a whole by two bolts and nuts, and the load-bearing frames The inner bolts are covered with positioning sleeves, and the integral fixed workbench is fastened on the lower plane of the load-bearing frame by bolts, and the upper part of the load-bearing frame is fixedly connected with an oil cylinder by bolts. The feature is: the oil cylinder is set to two The oil cylinder is respectively connected with two upper sliders through bolts and pressure rings, and the two upper sliders are slidingly matched with four guide rails on the load-bearing frame respectively.

The oil cylinders are respectively connected and driven with mutually independent hydraulic systems.

The length dimension of the fixed workbench is the sum of the length dimensions of the two upper sliders, and the width dimension is the same as that of the upper sliders.

Beneficial effects of the utility model: compared with the configuration of a large and a small press, the utility model can reduce the investment equivalent to a small press, and the output of small plates can be doubled. Fewer large plates can fully realize the functions of large presses, reduce the idle time of large presses, and completely solve the shortcomings of large presses such as inconvenience, unsafety, low efficiency and high energy consumption in pressing small plates.

Detailed ways:

The specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing:

As shown in the figure, a combined plate hydraulic press includes two load-bearing frames 1 and 11. The load-bearing frames 1 and 11 can be of prestressed steel wire winding type or stacked plate type, and a bolt pretension box Form, the lower beam part of the two load-bearing frames is fixed by two bolts 8 and nuts 9 to form a whole, and the bolts on the inner side of the load-bearing frame are covered with positioning sleeves 10 to ensure that the two frames 1 and 11 are in a certain relative position. function, the integral fixed workbench 7 is fastened on the lower plane of the load-bearing frame through bolts 12, and the upper part of the load-bearing frame is fixedly connected with an oil cylinder through bolts. The circle 4 is connected with two upper sliders 5, 13 and moves up and down, and the two upper sliders are slidingly matched with four guide rails 6 on the load-bearing frame respectively. The oil cylinders are respectively connected and driven with mutually independent hydraulic systems. The length dimension of the fixed workbench is the sum of the length dimensions of the two upper sliders, and the width dimension is the same as that of the upper sliders.

Embodiment 1, when it is necessary to use two small hydraulic presses to press small-sized plates, the working oil cylinders 2 and 15 are respectively driven by independent hydraulic systems, and are placed on the fixed table 7 in pairs through two upper sliders 5 and 13. The small-area mold at the end is pressed. At this time, two small hydraulic machines can press the two kinds of plates. The return stroke of the two worktables can be realized through the working cylinder or another return cylinder. The hydraulic press operates on both ends so there is no inconvenience and inefficiency associated with pressing small plates with a large press.

Embodiment 2, when large-area plates need to be pressed, the pressing spring mold 14 combined by the upper mold 14-1 and the lower mold 14-2 is installed on the fixed workbench, and several guides are arranged between the upper and lower molds. Column 17 and spring 16 to ensure the centering between the upper and lower dies. The mold is always in the open state under the action of the spring, and only when the two upper sliders press its upper mold at the same time, the upper mold will press against the plate placed on the lower mold. After pressing, with the return stroke of the two upper sliders, the upper mold also returns to the original open position under the action of the spring. The upper mold of this structural mold is not fixed on the upper slider, and there is no requirement for the synchronization of the two upper sliders during the return stroke. When pressing down, because the positions of the two upper sliders are adjusted to be almost the same as the upper mold, so When pressurizing downward in a short distance, synchronization is easier to realize, thereby achieving the purpose of pressurizing the same large-area plate mold by the split upper slider.

The above description is only a preferred embodiment of the combined plate press, and does not limit its structure in any way. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the present utility model.
