Description

Technical fields:

[0001] This utility model belongs to the field of horizontal warm isostatic press manufacturing, and particularly relates to a sealing and installation device for the plug workpiece of a horizontal warm isostatic press. Background technology:

[0002] An isostatic press is a molding device that operates under ultra-high pressure. Isostatic pressing involves placing the object to be processed in a specific mold, then placing the mold containing the workpiece into a sealed container filled with liquid. The pressure is gradually increased through a pressurization system, and the pressure is transmitted through the liquid, so that all surfaces of the object are subjected to equal pressure, and the object is formed under the constraint of the mold.

[0003] The main system of a horizontal isostatic press mainly consists of a prestressed frame, a working vessel that withstands ultra-high pressure, end caps, and a mounting base plate. The primary function of the end caps is to seal the openings at both ends of the ultra-high pressure working vessel. In existing technology, when assembling the end caps, rubber sealing rings need to be filled into the annular grooves reserved at their ends. On-site workers typically use pry bars to install these sealing rings. This installation method is not only time-consuming and labor-intensive but also inefficient. Furthermore, using a pry bar can easily cause localized deformation of the sealing ring, resulting in damage and rendering it unusable. Summary of the Invention:

[0004] The purpose of this utility model is to provide a sealing installation device for the plug workpiece of a horizontal isostatic press, and to overcome the shortcomings of the prior art. It effectively solves the existing problem of time-consuming and laborious installation of sealing rings for plug workpieces.

[0006] Furthermore, a second chamfer is provided at the bottom end of the cylindrical cap.

[0007] Furthermore, the first chamfer is 50 degrees and the second chamfer is 40 degrees.

[0008] Furthermore, a round rod is coaxially mounted on the top cross-section of the cylindrical cap, and a slot matching the round rod is provided on the bottom cross-section of the cap.

[0009] Furthermore, the auxiliary clamping assembly includes a pair of upright plates with screw holes on the upright plates, bolts screwed into the screw holes, and rubber clamps installed at the inner ends of the bolts.

[0010] Furthermore, a third chamfer with the same size as the first chamfer is formed along the inner edge of the bottom end of the flexible support bar.

[0011] Furthermore, a pressure edge is provided on the outer edge of the bottom end of the flexible support strip.

[0012] Furthermore, a circular placement groove matching the bottom end of the plug workpiece is provided on the top wall of the processing table.

[0013] Furthermore, a tool drawer is provided on the processing table.

[0014] The beneficial effects of this utility model are: by using a combination of a support cap, a flexible support strip, and a cylindrical buckle cap, a circular rubber sealing ring can be quickly and without damage installed onto the plug workpiece, thereby improving the sealing installation of the plug.

Detailed implementation method:

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0020] like Figures 1 to 3As shown, a horizontal isostatic press plug sealing installation device includes a processing table 1, a frame 2 mounted on the top wall of the processing table 1, a cylinder 3 vertically mounted downwards on the crossbeam of the frame 2, a support cap 4 mounted on the piston rod of the cylinder 3, several flexible support strips 5 evenly spaced along the elongation direction on the circumferential surface of the support cap 4, and a cylindrical buckle cap 6 below the support cap 4. The top and bottom cross-sections of the cylindrical buckle cap 6 are respectively provided with a first chamfer 7 and a circular groove 8. The cylindrical buckle cap 6 is fastened to the top of the plug workpiece 9 through the matching circular groove 8. The plug workpiece 9 is placed on the top wall of the processing table 1. An auxiliary clamping assembly is provided on the top wall of the processing table 1. A second chamfer 10 is provided at the bottom end of the cylindrical cap 6. The first chamfer 7 is 50 degrees and the second chamfer 10 is 40 degrees. A round rod 11 is coaxially installed on the top cross-section of the cylindrical cap 6. A slot 12 matching the round rod 11 is provided on the bottom cross-section of the support cap 4. A third chamfer 16 with the same size as the first chamfer 7 is provided on the inner edge of the bottom end of the flexible support bar 5. A pressing edge 17 is provided on the outer edge of the bottom end of the flexible support bar 5.

[0021] Specifically, by using the combination of the support cap 4, the flexible support strip 5 and the cylindrical buckle cap 6, the circular rubber sealing ring 20 can be quickly and without damage installed onto the plug workpiece 9.

[0022] In actual use, the plug workpiece 9 is first placed on the top wall of the processing table 1 and aligned with the support cap 4. Then, the cylindrical buckle cap 6 is fastened to the top of the plug workpiece 9 through the matching circular groove 8. Next, the relatively small circular rubber sealing ring 20 is fitted onto the first chamfer 7 of the cylindrical buckle cap 6. At this time, the cylinder 3 is started to drive the support cap 4 to descend. When the bottom ends of several flexible support strips 5 come into contact with the inclined surface of the first chamfer 7 of the cylindrical buckle cap 6, they gradually open in an umbrella shape. During the continuous descent of several flexible support strips 5, the circular rubber sealing ring 20 is pushed down on the cylindrical buckle cap 6 and finally matched and fitted into the annular groove reserved in the plug workpiece 9. After the installation is completed, the support cap 4 is raised and several flexible support strips 5 return to their original state.

[0023] In the above process, when the circular rubber sealing ring 20 is pushed to the bottom of the cylindrical cap 6, the second chamfer 10 can further guide the circular rubber sealing ring 20 to slide quickly into the annular groove reserved in the plug workpiece 9; the on-site staff can hold the round rod 11 to quickly fasten the cylindrical cap 6 onto the top of the plug workpiece 9. When the support cap 4 continues to descend, the round rod 11 can be inserted into the slot 12; the third chamfer 16 can make the flexible support strip 5 slide more smoothly on the inclined surface of the first chamfer 7 of the cylindrical cap 6, and the pressing edge 17 can increase the pushing contact surface of the bottom end of the flexible support strip 5 to the circular rubber sealing ring 20, further improving the installation efficiency of the circular rubber sealing ring 20; the flexible support strip 5 is a plastic material that can be deformed and restored to its original shape in the prior art, which will not be described in detail here.

[0024] like Figures 1 to 3 As shown, the horizontal isostatic press plug workpiece sealing installation device includes an auxiliary clamping assembly comprising a pair of vertical plates 13, with screw holes on the vertical plates 13, and bolts 14 screwed into the screw holes. A rubber clamping block 15 is installed at the inner end of the bolts 14. A circular placement groove 18 matching the bottom end of the plug workpiece 9 is provided on the top wall of the processing table 1. A tool drawer 19 is provided on the processing table 1.

[0025] Specifically, the plug workpiece 9 can be further fixed by the auxiliary clamping assembly, thereby preventing it from shifting.

[0026] In actual use, the plug workpiece 9 is placed in the circular placement groove 18, and the plug workpiece 9 and the support cap 4 can be coaxial, thereby further improving the installation efficiency; then the bolt 14 is rotated so that the two rubber clamps 15 clamp the plug workpiece 9 to prevent it from shifting, thereby further improving the stability of the plug workpiece 9 when the circular rubber sealing ring 20 is installed.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
