Description

Technical Field

[0001] The utility model relates to the technical field of industrial equipment, and more specifically, the utility model relates to a packing seal limit extrusion tooling. Background Art

[0002] It is known that packing seals are widely used in various industrial equipment and are also called packing; after the packing is installed in the packing cavity, it is axially compressed by the gland screws. When there is relative movement between the shaft and the packing, due to the plasticity of the packing itself, it generates a radial force and is in close contact with the shaft to obtain a seal and prevent the medium from leaking; multiple squeezes cause the packing compression force to relax and the sealing performance to decline, so the packing needs to be replaced regularly; among them, the packing is usually a strip with a square cross-section. In actual work, since the cross-section of the packing is not less than the gap of the packing groove, the assembly process is difficult. It is often necessary to pre-extrude the packing to change its thickness and shape dimensions, so as to assemble smoothly and simplify the subsequent work of packing adjustment, so that the packing thickness dimension can meet the equipment operation needs as soon as possible and reduce the running-in period.

[0003] However, in actual use, the traditional packing extrusion tooling has problems such as low efficiency, complex operation, and uneven extrusion effect. Therefore, a packing seal limit extrusion tooling is proposed as a further improvement. Summary of the Utility Model

[0013] Further, the moving bracket is fixed on the upper plate by at least two positioning fixed rods and two first knobs.

[0014] Further, the limiting and moving mechanism includes: a limiting pull rod and a second knob, one end of the limiting pull rod is threadedly connected to the end of the moving bracket away from the fixed bracket, the other end of the limiting pull rod passes through the fixed seat, the end of the limiting pull rod passing through the fixed seat is fixedly connected to the second knob, and the limiting pull rod is rotationally connected to the fixed seat.

[0018] Further, the size of the main rotating roller is the same as that of the slave rotating roller; the height of the center line of the main rotating roller is consistent with the height of the center line of the slave rotating roller.

[0019] Further, the width of the rectangular groove is greater than the diameter of the positioning fixed rod, and the width of the rectangular groove is less than the width of the moving bracket, and the diameter of the first knob is greater than the width of the rectangular groove.

[0020] The technical effects and advantages of the present utility model:
