Description

Technical Field

[0001] This utility model relates to the field of safety device technology, specifically a top hammer protection device for a six-sided top press. Background Technology

[0002] A six-sided top press is a device used to synthesize superhard materials under high temperature and high pressure. Its basic principle is to create a high-temperature and high-pressure environment using high pressure in six directions to promote material synthesis. The top hammers of the six-sided top press are a key component of this equipment, used to withstand extremely high pressure and temperature during the synthesis process. In a six-sided top press, the top hammers are divided into heated hammers and unheated hammers, which is to better control the high-temperature and high-pressure conditions required during the synthesis process. Under normal operating conditions, the heated and unheated hammers are in an insulated state. If the heated and unheated hammers come into contact under high pressure, it may cause damage to internal components of the equipment, or even lead to more serious safety accidents. Furthermore, contact may cause localized overheating, affecting the stability and safety of the equipment. Ensuring an appropriate distance between the heated and unheated hammers is crucial for maintaining the high-temperature and high-pressure conditions during the synthesis process, which directly affects product quality and yield.

[0003] A top hammer with a protective device, Chinese patent application number 201120391436.X, includes a first top hammer and a second top hammer. The first top hammer and the second top hammer are connected in an AC / DC conversion circuit. The AC / DC conversion circuit is connected to a relay control system. The relay is controlled by the control system and connected to a controller.

[0004] The existing six-sided top press top hammer protection device is not convenient for detecting whether the heated hammer and the non-heated hammer are in contact during use, which reduces the protection effect of the top hammer and easily leads to the breakage and damage of the top hammer. Summary of the Invention

[0005] The purpose of this utility model is to provide a top hammer protection device for a six-sided top press, which has the advantage of good protection effect. It solves the problem that the existing top hammer protection devices for six-sided top presses are not convenient to detect whether the heated hammer and the non-heated hammer are in contact during use, which reduces the protection effect of the top hammer and easily leads to the breakage and damage of the top hammer.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A protective device for the top hammer of a six-sided top press includes a protective mechanism and two connecting mechanisms; one end of each of the two connecting mechanisms is fixedly sleeved on the heating hammer and the non-heating hammer, and the other end of each of the two connecting mechanisms is electrically connected to the protective mechanism; when the heating hammer and the non-heating hammer are in a connected state, the protective mechanism cuts off the power supply line of the top press and issues an alarm.

[0008] In some embodiments, the connection mechanism includes:

[0009] Installation collars are respectively fitted onto the heating hammer and the non-heating hammer, and fixed together with them;

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 A protective device for the top hammer of a six-sided top press includes a protective mechanism 1 and two connecting mechanisms 2; one end of each connecting mechanism 2 is fixedly sleeved on the heating hammer 3 and the non-heating hammer 4, and the other end of each connecting mechanism 2 is electrically connected to the protective mechanism 1; when the heating hammer and the non-heating hammer are in a connected state, the protective mechanism 1 cuts off the power supply line of the top press and issues an alarm.

[0033] The following provides a further explanation of the connection mechanism described above.

[0034] like Figure 3 As shown, the connecting mechanism 2 includes a mounting collar 201 and a connecting wire 205; the mounting collar 201 is respectively fitted onto the heating hammer and the non-heating hammer and fixed together with them; one end of the connecting wire 205 is connected to the mounting collar 201 through a first connector, and the other end is connected to the protection mechanism 1 through a second connector.

[0035] Further plans will continue to be considered. Figure 3 As shown, the first connector consists of a threaded seat 208 fixed on the mounting collar 201 and a threaded head 206 fixed on the end of the wire, and the threaded head 206 can be screwed into the threaded seat 208; the second connector consists of a socket 104 fixed on the protection mechanism 1 and a plug 204 fixed on the end of the wire, and the plug 204 can be inserted into the socket 104.

[0036] Further plans will continue to be considered. Figure 3 As shown, multiple axially arranged threaded tubes 202 are fixed on the mounting collar 201 at intervals along its circumference. The threaded tubes 202 are internally connected with mounting bolts 203. The heating hammer and the non-heating hammer are provided with threaded holes corresponding to the threaded tubes 202. The mounting collar 201 is fixed to the heating hammer and the non-heating hammer respectively by tightening the mounting bolts 203.

[0037] Further plans will continue to be considered. Figure 3 As shown, a support rod 207 is fixedly connected to the surface of the threaded seat 208, and the support rod 207 abuts against the heating hammer 3 and the non-heating hammer 4.

[0038] The following provides further explanation of the aforementioned protection agencies.

[0039] like Figure 2 , Figure 4 As shown, the protection mechanism 1 includes a housing 101, a relay 106 located on the housing 101, a transformer 107, and an alarm component; the housing 101 has sockets 104 at both ends for electrical connection with the connection mechanism 2; the transformer 107 is connected in series in the circuit for connecting the two sockets 104, and is used to transform the voltage when the heating hammer and the non-heating hammer are connected; the coil of the relay 106 is connected in series in the circuit for connecting the two sockets 104; the first normally closed contact of the relay 106 is connected in series in the power supply line of the press machine; and the second normally open contact of the relay 106 is connected in series in the circuit of the alarm component.

[0040] Further plans will continue to be considered. Figure 2 , Figure 4As shown, the alarm component is a buzzer alarm 103. After the second normally open contact of the relay 106 closes, the circuit of the buzzer alarm 103 is activated, causing the buzzer alarm 103 to sound an alarm.

[0041] Further plans will continue to be considered. Figure 2 , Figure 4 As shown, the protection mechanism 1 also includes a switch button 102, which is connected in series in the circuit of the alarm component.

[0042] Further plans will continue to be considered. Figure 2 , Figure 4 As shown, the protection mechanism 1 also includes an emergency stop switch 105, which is connected in series with the power supply line of the top press.

[0043] As can be seen from the above, by setting the protection mechanism 1, it is easy to detect whether the heating hammer 3 and the non-heating hammer 4 are insulated. Under normal working conditions, the heating hammer 3 and the non-heating hammer 4 do not contact each other and are in an insulated state. When the heating hammer 3 and the non-heating hammer 4 are in a connected state, it represents a fault state. After receiving the electrical signal transmitted by the connection mechanism 2, the protector mechanism 1 cuts off the main circuit through the relay 106 to prevent further power supply. The transformer 107 ensures that the voltage in the circuit is suitable for the operation of the protector 101. At this time, the buzzer alarm 103 is activated and emits an audible alarm. The buzzer alarm 103 is immediately stopped by the action of the switch button 105.

[0044] By setting the connecting mechanism 2, the auxiliary protection mechanism 1 can easily detect the heating hammer 3 and the non-heating hammer 4. The mounting collar 201 is fitted onto the surface of the heating hammer 3 and the non-heating hammer 4. The mounting bolt 203 is screwed into the heating hammer 3 and the non-heating hammer 4 through the threaded tube 202 to achieve the effect of fixing the mounting collar 201. The threaded head 206 is screwed into the threaded seat 208 to realize the electrical connection between the mounting collar 201 and the wire 205 and the heating hammer 3 and the non-heating hammer 4. The connecting wire 205 is installed on the socket 104 through the plug 204 to realize the electrical connection with the protection mechanism 1. The support rod 207 supports the surface of the threaded seat 208 to prevent it from deforming.

[0045] Feedback on the technical solution of this utility model: According to the above solution and the expected experimental results; the on-site simulation showed that the insulation between the heated hammer and the non-heated hammer was damaged due to the core column angle being extended caused by the falling of the sealing edge of pyrophyllite in the early stage of synthesis, the hammer being paralyzed and dead during synthesis, etc.; when the synthesis personnel used the saw blade to overlap the heated hammer and the non-heated hammer when the press was moving forward in the idle stroke, the press showed an immediate stop state; after confirming that there was no abnormality, the switch was adjusted and the press continued to work.

[0046] Based on the simulation results under normal conditions, the synthesis workshop operated four presses (63#-66#) continuously from February 22nd to June 22nd, 2024, for a total of four months. During this period, several issues arose: a slight chipping of the top hammer during right hammer synthesis, causing it to connect with other nearby hammers; pyrophyllite chips losing their sealing edge in the early stages of synthesis; slight leakage from the sealing edge of the synthesis core column, resulting in insulation damage between the top hammers; and a dead hammer activation during hammer adjustment by a press mechanic, causing the activated top hammer's steel ring to contact other top hammer steel rings. All these issues were addressed with the device, triggering alarms and stopping the machine, preventing top hammer blasting accidents and effectively protecting other top hammers from damage. Currently, the equipment is operating stably and is beneficial for detecting accidents such as pyrophyllite chipping from the sealing edge, core column deformation, top hammer activation, and dead hammer activation in the early stages of synthesis, thus ensuring safe production.
