Description

Technical Field

[0001] This utility model relates to the field of six-sided top press technology, and in particular to a safe connection structure between the large pad block and the steel ring of a six-sided top press. Background Technology

[0002] In the high-pressure synthesis system of a six-sided top press, the connection structure between the large pad and the steel ring directly affects the safety and stability of the equipment operation. Traditional connection methods often use single bolt fastening or simple snap-fit ​​structures. These structures are prone to loosening, slippage, or even detachment during installation or disassembly, posing serious safety hazards. Especially in scenarios where the steel ring needs to be frequently disassembled to replace components such as hammers, existing structures often lack reliable circumferential limiting and axial locking mechanisms, resulting in cumbersome installation, low positioning accuracy, and difficulty in effectively preventing the steel ring from rotating or shifting axially due to torque or impact loads during equipment operation. Furthermore, although some structures introduce pin positioning, their disassembly and assembly rely on special tools or complex operating procedures, which are not only inefficient but also prone to component damage or safety accidents if the pin is not fully reset or if misoperation occurs. Therefore, there is an urgent need for a connection structure that can achieve both rapid assembly and reliable locking, while also providing multiple anti-loosening safeguards, to improve the connection safety and maintenance convenience of key components in a six-sided top press. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model discloses a safe connection structure between the large pad block and the steel ring of a six-sided top press.

[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0005] A safety connection structure between a large pad block and a steel ring in a six-sided top press includes:

[0006] Large pad, which has a conical structure;

[0007] Two arc-shaped grooves are located at the small end of the large pad, and the two arc-shaped grooves are spaced 180 degrees apart;

[0008] Two openings are located at one end of two arc-shaped grooves, and the two openings are symmetrically arranged.

[0009] A settling trough is located within one of the arc-shaped troughs; the depth of the settling trough is greater than the depth of the arc-shaped trough.

[0010] A steel ring is installed at the small end of the large pad.

[0011] The movable pin is installed at one of the arc-shaped grooves on the steel ring; and the movable pin is movably inserted into the steel ring and can be inserted into the groove.

[0012] A retaining pin is installed on the steel ring at the position corresponding to another arc-shaped groove;

[0013] The locking bolts are multiple bolts installed at intervals along the circumference of the steel ring; when the locking bolts are tightened, they can make corresponding contact with the large pads.

[0014] Preferably, the insertion hole for the movable pin in the steel ring is a stepped hole, and an annular boss is provided at one end of the movable pin located in the stepped hole. A spring is sleeved on the rod body of the movable pin corresponding to the annular boss and the stepped surface of the stepped hole.

[0015] Preferably, the movable pin is vertically mounted with a stirring shaft, and the steel ring is provided with a sliding groove corresponding to and adapted to the stirring shaft at the stepped hole.

[0016] Preferably, the settling groove is a strip groove, and the longitudinal axis of the strip groove is parallel to the axis of the large pad, and the diameters of the movable pin and the fixed pin are both smaller than the width of the arc-shaped groove.

[0017] Preferably, the large pad has a chamfered structure at the positions corresponding to the two openings.

[0018] Preferably, there are three locking bolts evenly spaced apart.

[0019] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0020] (1) The safety connection structure design of the large pad and steel ring of this utility model effectively improves the safety and reliability of equipment operation through a multi-redundant locking mechanism. The large pad adopts a conical structure design, and its special arc groove and countersunk groove structure at the small end provide a unique insertion path for the movable pin, ensuring that the steel ring can be circumferentially locked after installation and preventing accidental reverse rotation. The locking bolts configured on the steel ring are firmly fixed to the large pad by axial clamping force, effectively avoiding the risk of accidental detachment due to loosening. At the same time, the fixing pin provides auxiliary guidance and limit support during rotation, ensuring the stability of the steel ring during rotation. This series of measures together constitute a safe and reliable connection system, which not only improves the overall operational safety of the device, but also simplifies the maintenance process.

[0021] (2) The optimized design of the movable pin in this utility model further enhances the convenience and reliability of assembly. By setting a spring in the insertion hole on the steel ring, the movable pin can be automatically inserted when aligned with the sinker, realizing automatic positioning and locking functions without the need for additional external force. This design greatly improves assembly efficiency and reduces the workload of operators. In addition, the design of the stirring shaft installed vertically on the movable pin and its corresponding sliding groove significantly reduces the difficulty of operation during disassembly and improves maintenance efficiency.

[0022] (3) This utility model further improves the assembly accuracy and operational stability of the whole machine by designing a strip groove for the sink and adjusting the number and arrangement of the locking bolts. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] Example 1:

[0034] Combined with appendix Figures 1-4 A safe connection structure between a large pad and a steel ring in a six-sided jacking press includes a large pad 1, a steel ring 5, a movable pin 6, a fixed pin 7, and a locking bolt 8. The large pad 1 has a conical structure; its large end is used to connect to the main body of the six-sided jacking press, and its small end is used to install the steel ring 5. (See attached diagram) Figure 3 and attached Figure 4 As shown, two arc-shaped grooves 2 are formed circumferentially at the small end of the large pad 1, and the two arc-shaped grooves 2 are arranged 180 degrees apart in the circumferential direction. Each arc-shaped groove 2 has an opening 3 at one end, and the two openings 3 are symmetrically arranged. A recessed groove 4 is provided near the inner end of one of the arc-shaped grooves 2, and the depth of the recessed groove 4 is greater than the groove depth of the arc-shaped groove 2.

[0035] A steel ring 5, matching its shape, is fitted to the small end of the large pad 1. This steel ring 5 is used to install components such as hammers. A movable pin 6 is provided on the steel ring 5 corresponding to one of the arc-shaped grooves 2. The movable pin 6 can be inserted radially into the arc-shaped groove 2. When installing the steel ring 5, first align the movable pin 6 with the corresponding opening 3, and simultaneously align the fixed pin 7 with the opening 3 on the other side, so that the movable pin 6 and fixed pin 7 respectively enter the corresponding arc-shaped groove 2; then rotate the steel ring 5, causing the movable pin 6 to slide along the arc-shaped groove 2. When the movable pin 6 reaches the position of the recess 4 and aligns with it, the movable pin 6 can be inserted into the recess 4 under the action of gravity or external force, thereby achieving circumferential locking of the steel ring 5 and preventing accidental reverse rotation. (See attached...) Figure 2 As shown, the fixing pin 7 is fixedly installed at the position of the other arc groove 2 corresponding to the steel ring 5. Its function is to provide auxiliary guidance and limit support during the rotation of the steel ring 5, so as to ensure that the steel ring 5 remains stable during the rotation.

[0036] Furthermore, the large pad 1 has a chamfered structure at the entrance of both openings 3. This chamfered structure can effectively reduce the resistance when the movable pin 6 and the fixed pin 7 are inserted into the opening 3, thereby improving assembly efficiency.

[0037] In addition, multiple locking bolts 8 are spaced apart along the circumference of the steel ring 5, and each locking bolt 8 is threadedly connected to the steel ring 5 through a through hole. When the locking bolt 8 is tightened, its end abuts against the outer surface of the large pad 1, thereby axially pressing the steel ring 5 onto the large pad 1 and preventing the steel ring 5 from accidentally falling off due to loosening during equipment operation.

[0038] When it is necessary to disassemble the steel ring 5, first loosen all the locking bolts 8, then manually pull the movable pin 6 outward to remove it from the recess 4; next, rotate the steel ring 5 in the opposite direction so that the movable pin 6 and the fixed pin 7 return to their respective openings 3 positions, at which point the steel ring 5 can be removed from the large pad 1. This structure, through the synergistic action of the movable pin 6, the fixed pin 7, and the locking bolts 8, constitutes a multi-redundant locking mechanism, effectively preventing the steel ring 5 from accidentally falling off during installation and disassembly, thus improving operational safety and reliability.

[0039] Example 2:

[0040] Combined with appendix Figures 5-6 A safe connection structure between a large pad block and a steel ring in a six-sided top press differs from Embodiment 1 in that the installation structure of the movable pin 6 is optimized based on Embodiment 1. Specifically, the insertion hole on the steel ring 5 for installing the movable pin 6 is designed as a stepped hole, and one end of the movable pin 6 located in the stepped hole has an annular boss. A spring 9 is fitted onto the portion of the movable pin 6 located between the annular boss and the stepped surface of the stepped hole. One end of the spring 9 abuts against the annular boss, and the other end abuts against the stepped surface of the stepped hole. During the installation of the steel ring 5, when the movable pin 6 rotates with the steel ring 5 to align with the recess 4, the elastic force of the spring 9 pushes the movable pin 6 to automatically insert into the recess 4, achieving automatic positioning and locking without the need for additional external force, thus improving the convenience and reliability of assembly.

[0041] Furthermore, a stirring shaft 10 is vertically mounted on the shaft of the movable pin 6, and a groove adapted to the stirring shaft 10 is provided on the steel ring 5 at the corresponding position of the stepped hole. When disassembling the steel ring 5, the operator can first pull the movable pin 6 outward, causing the stirring shaft 10 to move along the groove and eventually disengage from the stepped hole; then, the movable pin 6 is rotated around its own axis by a certain angle, causing the stirring shaft 10 to be locked at the edge of the stepped hole, thus keeping the movable pin 6 in the disengaged state without requiring the operator to continuously apply force to pull it out. This structure significantly reduces the operational difficulty during disassembly and improves maintenance efficiency.

[0042] Example 3:

[0043] Combined with appendix Figures 2-3A safe connection structure between the large pad block and the steel ring in a six-sided top press is proposed, further optimizing the structure of the settling groove 4 based on Embodiment 1 or Embodiment 2. Specifically, the settling groove 4 is designed as a strip-shaped groove, with its length axis parallel to the central axis of the large pad block 1. Simultaneously, the diameters of the movable pin 6 and the fixed pin 7 are both smaller than the width of the arc-shaped groove 2, allowing the steel ring 5 to retain a certain degree of axial freedom before the locking bolt 8 is fully tightened. This design facilitates fine-tuning of the axial position of the steel ring 5 during assembly, ensuring that its relative position with the large pad block 1 and other components meets installation requirements.

[0044] Furthermore, the number of locking bolts 8 is set to three, and they are evenly spaced along the circumference of the steel ring 5. The three locking bolts 8 provide sufficient axial clamping force, and by adjusting the tightening degree of each bolt individually, the coaxiality between the steel ring 5 and the large pad 1 can be finely adjusted, thereby improving the overall assembly accuracy and operational stability. This structure ensures reliable connection while also taking into account assembly flexibility and ease of adjustment.

[0045] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
