Description

Technical Field

[0001] The utility model relates to the field of artificial synthetic diamonds, in particular to a diamond press top hammer steel ring pulling device. Background Art

[0002] The six-sided top press is precision-designed, easy to operate, and offers excellent heating repeatability. In recent years, China's six-sided top press technology has continued to advance, including larger presses, improved carbide anvils, and the industrialization of powder catalysts and indirect heating processes. These advancements have significantly improved diamond production rates and quality.

[0003] During the production process of the diamond press, due to the long-term pressure on the large pads, their ends will have different degrees of expansion and deformation. After the ends are swollen, the steel ring screws will be difficult to loosen and the top hammer will not be easy to correct. At this time, the large pads need to be removed for reprocessing; but because the ends of some large pads are deformed too much, the inner wall of the steel ring will stick to the large pads and cannot be removed. In the past, when this happened, the steel ring could only be cut open by gas cutting, which caused damage to the steel ring. Improper operation may even cause the top hammer to crack due to local heat, resulting in large wear and tear of parts and serious economic losses. Utility Model Content

[0024] Example 1, see attached Figure 1-2 , a pulling device for the top hammer steel ring 52 of a diamond press, the main body of the device is a supporting disc 1, and the edge of the supporting disc is evenly distributed with at least three through holes 11, and an L-shaped pull rod 2 is slidably inserted into the through hole, and the lower end of the L-shaped pull rod is a right-angle hook body 21 for hooking the bottom surface of the large pad 53, and the upper end of the L-shaped pull rod 2 is provided with a threaded section, on which a pulling nut 22 is installed. At least three cylindrical legs 12 are evenly distributed on the edge of the bottom surface of the supporting disc 1, and the cylindrical legs are used to support the end face edge of the press piston rod 51, and the large pad 53 is fixedly connected to the middle part of the piston rod. The length of the cylindrical legs 12 is greater than the length of the L-shaped pull rod 2, and the number of L-shaped pull rods is the same as the number of cylindrical legs 12, and the L-shaped pull rods 2 and the cylindrical legs 12 are staggered at equal intervals.

[0025] When the pulling device of this embodiment is used, its cylindrical support leg 12 is supported on the end edge of the press piston rod 51, and the position of the L-shaped pull rod 2 is adjusted so that its right-angle hook body 21 hooks the bottom edge of the large pad 53. Then, the retracting nut 22 is screwed one by one to pull the L-shaped pull rod 2 outward. The evenly arranged L-shaped pull rod 2 slowly pulls out the large pad 53 together with the steel ring 52, and the steel ring 52 gradually separates from the enlarged large pad 53, and the steel ring is taken out without damage.

[0026] Embodiment 2: Based on embodiment 1, this embodiment has a triangle plate 3 provided in parallel in the middle of the upper surface of the support disc 1, and a through hole B 31 is provided at the three corners of the triangle plate. The through hole B 31 and the through hole A 11 are directly opposite to each other, and the through hole B is correspondingly inserted into the upper end of the L-shaped pull rod 2. The pulling nut 22 is located above the triangle plate 3. The pulling nut 22 is used to limit and support the upper surface of the triangle plate. The upper ends of the L-shaped pull rod 2 are connected to each other through the triangle plate 3. A main support screw 13 is provided in the center of the upper surface of the support disc 1. The main support screw extends from the circular hole in the center of the triangle plate 3. A push nut is provided on the main support screw 13 between the triangle plate 3 and the support disc 1.

[0027] When the pulling device of this embodiment is used, a wrench is inserted into the gap between the triangular plate 3 and the supporting disc 1, and the pushing nut is rotated from the gap. The pushing nut moves upward along the main support screw 13, pushing the bottom surface of the triangular plate. The triangular plate 3 moves upward along the main support screw 13, and the L-shaped pull rod 2 is pulled outward synchronously. There is no need to screw the pulling nut 22 one by one. Only the pushing nut needs to be screwed to achieve the synchronous movement of multiple L-shaped pull rods 2. The operation is simple and efficient.

[0028] The three corners of the triangle plate 3 are provided with transition arcs, and the side panels of the triangle plate 3 are inwardly concave arc structures. This structural design is not only beautiful, but also helps to reduce the weight of the triangle plate 3, meeting the lightweight design requirements.

[0029] Example 3, see attached Figure 3-6 , based on the first embodiment, this embodiment has a triangular plate 3 provided parallel to the middle of the upper surface of the support disc 1, and through holes B 31 are provided at the three corners of the triangular plate. Through hole B and through hole A 11 are directly opposite to each other, and through hole B is correspondingly inserted into the upper end of the L-shaped pull rod 2. The pulling nut 22 is located above the triangular plate 3. The pulling nut 22 is used to limit and support the upper surface of the triangular plate 3. The upper ends of the L-shaped pull rod 2 are connected to each other through the triangular plate 3. A main support screw 13 is provided in the center of the upper surface of the support disc 1. The main support screw extends from the circular hole in the center of the triangular plate 3. A main nut 4 is mounted on the main support screw 13. The bottom surface of the main nut is provided with a sleeve 41 in a rotating sleeve circular hole. When the main nut 4 is rotated, the sleeve 41 can rotate in the circular hole in the center of the triangular plate 3. The bottom surface of the sleeve is provided with an annular plate 42 supported on the bottom surface of the triangular plate 3.

[0030] When the pulling device of this embodiment is used, the main nut 4 at the end of the main support screw 13 is directly screwed, and the main nut moves upward along the main support screw 13. At the same time, the sleeve 41 rotates in the circular hole in the center of the triangular plate 3, and the surface of the annular plate 42 rotates relative to the bottom surface of the triangular plate 3 to lift the triangular plate 3. The triangular plate 3 moves upward along the main support screw 13 and synchronously pulls the L-shaped pull rod 2 outward. There is no need to screw the pulling nut 22 one by one. Only the pushing nut needs to be screwed to achieve the synchronous movement of multiple L-shaped pull rods 2. It can also overcome the problem of the second embodiment that a wrench needs to be inserted into the gap between the triangular plate 3 and the support disc 1 for screwing, which further improves the convenience of the drawing operation.

[0031] Both through hole A 11 and through hole B 31 are oblong holes, the length direction of the oblong holes is consistent with the radial direction of the support disc 1, and the through hole A 11 and through hole B 31 have the same size. The oblong holes can enable the L-shaped pull rod 2 to adjust its position radially on the support disc 1, so that the device can be suitable for drawing operations of steel rings 52 of different specifications.
