Description

Technical Field

[0001] The utility model relates to the technical field of floating sealing ring production, in particular to a pressing machine for producing floating sealing rings. Background Art

[0002] Floating seal, also known as floating oil seal or floating seal ring, is a mechanical seal used for rotating shaft sealing. It is mainly used to prevent lubricating oil or other liquids from leaking out of the gap between the shaft and the housing of the rotating equipment, and also to prevent external impurities from entering the equipment. The press is one of the equipment for producing floating seals.

[0003] Ordinary pressing machines usually do not have a blanking function. After the sealing ring is pressed and formed by the pressing machine, the sealing ring needs to be manually removed to complete the blanking. However, the sealing ring may stick to the inside of the mold after forming, resulting in a decrease in blanking efficiency. Therefore, a pressing machine for producing floating sealing rings is proposed to solve the above-mentioned problem. Utility Model Content

[0006] (2) Technical solution

[0007] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a pressing machine for producing floating sealing rings, comprising a table body, the top of the table body is fixedly connected to four supporting columns distributed in a rectangular array, the tops of the four support columns are fixedly connected to the same top plate, the bottom of the top plate is fixedly connected to a cylinder, the bottom of the cylinder is fixedly connected to an upper pressing block, an upper groove is provided inside the upper pressing block, the top of the table body is fixedly connected to a lower pressing block, the inside of the lower pressing block is fixedly connected to a lower groove, the depth of the upper groove is greater than the depth of the lower groove, the top of the upper pressing block is fixedly connected to four connecting columns distributed in a ring array, the outer sides of the four connecting columns are fixedly connected to electric push rods, the bottoms of the four electric push rods are fixedly connected to push rods, the four push rods are all adapted to the upper groove, and an electric heating plate is provided inside the lower pressing block.

[0008] The beneficial effects of the utility model are as follows: the lower pressing block is convenient for placing materials, the electric heating plate in the lower pressing block can heat the materials inside the lower pressing block through the lower pressing block, so that the materials inside the lower pressing block are convenient for pressing, and the cylinder drives the upper pressing block to press the materials into rubber rings through the upper and lower grooves after heating by the electric heating plate. Since the residual heat of the lower pressing block will remain in the lower pressing block after heating, the temperature of the lower pressing block is higher than that of the upper pressing block, and the contact area between the lower groove and the rubber ring is smaller than that between the upper groove and the rubber ring. After forming, when the cylinder drives the upper pressing block to rise, the upper pressing block drives the formed rubber ring to separate from the lower groove and the lower pressing block through the upper groove, and the four electric push rods drive the four push rods to push the rubber ring out through the upper groove, which is convenient for workers to take out and complete the material unloading.

[0009] The pressing machine for producing the floating sealing ring has the advantage of being easy to cut.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, four top blocks arranged in a circular array are fixedly connected to the interior of the lower pressing block, and the tops of the four top blocks are fixedly connected to the bottom of the electric heating plate.

[0012] The beneficial effect of adopting the above further solution is that the four top blocks can provide a more stable fixing effect for the heating plate through the lower pressing block.

[0013] Furthermore, four limiting rings are fixedly connected to the top of the upper pressing block and are distributed in a ring array. The inner sides of the four limiting rings are slidably connected to the outer sides of the four push rods respectively.

[0014] The beneficial effect of adopting the above further solution is that the four limiting rings can further limit the four push rods through the upper pressing block.

[0015] Furthermore, four positioning rods distributed in a ring array are fixedly connected to the top of the upper pressing block, and the outer sides of the four positioning rods are slidably connected to the inner side of the top plate.

[0016] The beneficial effect of adopting the above further solution is that the four positioning rods can provide a further limiting effect for the upper pressing block through the top plate.

[0017] Furthermore, the tops of the four positioning rods are fixedly connected to a same limiting plate, and the limiting plate is located above the top plate.

[0018] The beneficial effect of adopting the above further solution is that the limiting plate can provide a limiting effect for the four positioning rods through the top plate.

[0019] Furthermore, the bottom of the platform is fixedly connected with supporting legs, and the number of the supporting legs is four and distributed in a rectangular array.

[0020] The beneficial effect of adopting the above further solution is that the four supporting legs can elevate the platform body so that the platform body is more convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS
