Description

Technical Field

[0001] The utility model belongs to the technical field of superhard material synthesis equipment, and relates to a fixing device for a cushion block of a six-sided press. Background Art

[0002] Due to its extremely strong chemical inertness and excellent semiconductor properties, diamond has a wide range of uses in the fields of industry, national defense, scientific research, medical treatment, etc. It is often used as a high-hard cutting tool, a fine grinding material, a semiconductor material, an optical material, etc. As the world's largest producer of synthetic diamond, China mainly uses six-sided synthesis presses for the production and manufacturing of synthetic diamond domestically.

[0003] In a six-sided press, the cemented carbide anvil is a consumable key component, and the length of its service life directly determines the production cost of diamond synthesis. With the enlargement of the press equipment, the size and weight of the anvil steel ring become larger, and the rigidity of the steel ring is relatively reduced. The large cushion block is radially positioned and connected by the original four fastening bolts, and the anvil cannot be fixed and supported, resulting in the loosening of the anvil centering performance within a short time after calibration and the inability to meet the production requirements, which is extremely likely to cause a blasting accident. Therefore, solving the loss problem of the cemented carbide anvil in the actual production process can greatly improve the economic benefits of the enterprise. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for a cushion block of a six-sided press, which solves the problem that the anvil is prone to shaking and causing "blasting" after being stressed during use in the prior art.

[0005] The technical solution adopted by the utility model is that a fixing device for a cushion block of a six-sided press includes a steel ring. One end of the steel ring is connected with a lower cushion block along the axial direction of the steel ring. The other end of the steel ring is sleeved with an anvil. An upper cushion block adapted to the inner wall of the steel ring is arranged inside the steel ring, and the upper cushion block contacts the anvil.

[0006] The characteristics of the utility model also lie in that

[0007] The lower cushion block includes a column platform, and the column platform is connected with a base of a column body. The column platform extends into the steel ring and is closely attached to the inner wall of the steel ring, and the column platform contacts the upper cushion block.

[0008] A circular fixing plate is connected to the port of the steel ring near the lower cushion block. The fixing plate is perpendicular to the axis of the steel ring, and the fixing plate is connected to the end face of the base by bolts.

[0009] The fixing plate is provided with first connection holes at equal intervals along the circumferential direction. The base is provided with second connection holes opposite to the positions of the first connection holes near the end face of the steel ring. The first connection holes and the second connection holes are jointly matched with fastening bolts.

[0010] The interval between the fixing plate and the base is 0.03 mm to 0.05 mm.

[0011] The beneficial effects of the present utility model are as follows: By adopting a split connection structure of an upper cushion block and a lower cushion block, if any component is damaged, only the local part needs to be replaced instead of the whole; changing the connection bolts between the traditional steel ring and the lower cushion block from radial force to axial force makes the connection more firm; using fastening bolts for axial connection ensures the parallelism and perpendicularity among the six anvils, and can effectively reduce the phenomena of tipping and offset caused by unbalanced force between the steel ring and the anvils; reducing the cracking phenomena of the anvils caused by reasons such as misalignment, saving production costs, reducing the maintenance times of operators, and greatly improving production efficiency.

[0016] The present utility model will be described in detail below in conjunction with the drawings and specific embodiments.

[0017] The cushion block fixing device of the six-sided top press of the present utility model, as Figure 1 shown, includes a steel ring 2. One end of the steel ring 2 is connected with a lower cushion block 4 along the axial direction of the steel ring 2. The other end of the steel ring 2 is sleeved with an anvil 1. An upper cushion block 3 adapted to the inner wall of the steel ring 2 is arranged inside the steel ring 2, and the upper cushion block 3 is in contact with the anvil 1.

[0018] The lower cushion block 4 includes a column platform 9. The column platform 9 is connected with a base 10 in the shape of a column. The column platform 9 extends into the steel ring 2 and is in close fit with the inner wall of the steel ring 2, and the column platform 9 is in contact with the upper cushion block 3.

[0019] A ring-shaped fixing plate 5 is connected to the port of the steel ring 2 near the lower cushion block 4. The fixing plate 5 is arranged perpendicular to the axis of the steel ring 2, and the fixing plate 5 is connected to the end face of the base 10 by bolts.

[0020] As Figure 2 and Figure 3The fixing plate 5 is provided with first connecting holes 6 at equal intervals along the circumferential direction, and the base 10 is provided with second connecting holes 7 opposite to the first connecting holes 6 near the end face of the steel ring 2. The first connecting holes 6 and the second connecting holes 7 are jointly equipped with fastening bolts 8.

[0021] The distance between the fixing plate 5 and the base 10 is 0.03 mm to 0.05 mm.

[0022] The top hammer 1 and the steel ring 2 are connected by extrusion; the column base 9 contacts the inner wall of the steel ring 2 and the first connecting hole 6 and the second connecting hole 7 are connected by fastening bolts 8. The double connection and positioning ensure the centering of the top hammer 1 of the six-sided top press;

[0023] The lower pad 4 is cylindrical and is connected to the steel ring 2 and the lower pad 4 by fastening bolts 8 in conjunction with the first connecting hole 6 and the second connecting hole 7. When working after connection, the force direction is consistent with the connection direction, so the steel ring 2 and the lower pad 4 will not produce relative displacement, thereby increasing the fastening force between the steel ring 2 and the lower pad 4.

[0024] The upper pad 3 and the lower pad 4 are split into a structure. If any component is damaged, only part of it needs to be replaced instead of the whole component. The bolts 8 connecting the traditional steel ring 2 and the lower pad 4 are changed from radial force to axial force, and the connection is tighter. The fastening bolts 8 are used for axial connection to ensure the parallelism and verticality of the six top hammers, which can effectively reduce the rollover and offset of the steel ring 2 and the top hammer 1 due to unbalanced force. When the six-sided top press is working, the force transmission direction passes through the lower pad 4, the upper pad 3, and the top hammer 1 in turn to ensure the continuity of pressure transmission.

[0025] An adjustment gap of 0.03mm to 0.05mm is reserved between the steel ring 2 and the lower pad 4. The reserved adjustment gap facilitates the assembly of the six top hammers and enables adjustment, ensuring that the top hammers are assembled according to specifications.

[0026] Example 1

[0027] The pad fixing device of the six-sided top press includes a steel ring 2, one end of which is connected to a lower pad 4 along the axis of the steel ring 2. The other end of the steel ring 2 is sleeved with a top hammer 1. An upper pad 3 is installed inside the steel ring 2 to adapt to the inner wall of the steel ring 2, and the upper pad 3 is in contact with the top hammer 1. The lower pad 4 includes a column 9, which is connected to a column base 10. The column 9 extends into the steel ring 2 and fits tightly against the inner wall of the steel ring 2. The column 9 is in contact with the upper pad 3. An annular fixing plate 5 is connected to the end of the steel ring 2 near the lower pad 4. The fixing plate 5 is arranged perpendicular to the axis of the steel ring 2 and is connected to the end face of the base 10 by bolts.

[0028] After the anvil 1 and the steel ring 2 are assembled and the steel ring 2 and the lower spacer 4 are connected and fastened through the first connection hole 6 and the second connection hole 7, the positional relationship between the lower spacer 4 and the anvil 1 can be ensured. After the overall assembly of the six-anvil diamond synthesis press, the centering between the six anvils can be well ensured.

[0029] Embodiment 2

[0030] The spacer fixing device of the six-anvil press includes a steel ring 2. One end of the steel ring 2 is connected with a lower spacer 4 along the axial direction of the steel ring 2. The other end of the steel ring 2 is sleeved with an anvil 1. An upper spacer 3 adapted to the inner wall of the steel ring 2 is arranged inside the steel ring 2, and the upper spacer 3 contacts the anvil 1. The lower spacer 4 includes a column platform 9, and the column platform 9 is connected with a columnar base 10. The column platform 9 extends into the steel ring 2 and is in close fit with the inner wall of the steel ring 2, and the column platform 9 contacts the upper spacer 3. A circular fixing plate 5 is connected to the port of the steel ring 2 close to the lower spacer 4. The fixing plate 5 is arranged perpendicular to the axis of the steel ring 2, and the end face of the fixing plate 5 is connected to the end face of the base 10 by bolts. The fixing plate 5 is provided with first connection holes 6 at equal intervals in the circumferential direction. The base 10 is provided with second connection holes 7 opposite to the positions of the first connection holes 6 at the end face close to the steel ring 2. The first connection holes 6 and the second connection holes 7 are jointly fitted with fastening bolts 8.

[0031] Compared with the prior art, the connection method of the improved upper spacer 3 and lower spacer 4 has better mechanical properties, can withstand and conduct greater pressure, can effectively reduce the cracking phenomenon of the spacer, and reduce the frequency of maintenance and disassembly.

[0032] Embodiment 3

[0033] The spacer fixing device of the six-anvil press includes a steel ring 2. One end of the steel ring 2 is connected with a lower spacer 4 along the axial direction of the steel ring 2. The other end of the steel ring 2 is sleeved with an anvil 1. An upper spacer 3 adapted to the inner wall of the steel ring 2 is arranged inside the steel ring 2, and the upper spacer 3 contacts the anvil 1. The fixing plate 5 is provided with first connection holes 6 at equal intervals in the circumferential direction. The base 10 is provided with second connection holes 7 opposite to the positions of the first connection holes 6 at the end face close to the steel ring 2.

[0034] After testing on the six-anvil diamond synthesis press, through the preliminary assembly adjustment, the centering of the six anvils is greatly ensured. At the same time, due to the tighter connection, the relative displacement between the steel ring 2 and the lower spacer 4 is greatly reduced. The operator reduces the number of times of hammer alignment, and at the same time reduces the consumption of the anvil. The labor intensity is reduced, the production efficiency is improved, and the production cost is saved.
