[0002] In plastic products (such as circuit breakers), a hot riveting die is often used to fix two parts together by riveting. Among them, the hot riveting die includes a die base, a riveting head and a heating element connected to the die base. The riveting head is prone to wear during use, so the material used to make the riveting head is relatively hard, such as white steel, and its thermal conductivity is quite different from that of the die base and the heating element. Therefore, during the use of the hot riveting die, the actual temperature of the riveting head is quite different from the actual temperatures of the heating element and the die base.

[0065] This embodiment provides a hot riveting die. Refer to Figures 1 to 11 As shown, the hot riveting die includes a bracket 100, a riveting module 200, and a temperature control module 300.

[0066] Specifically, a carrier 110 is provided on the bracket 100, and the carrier 110 is used to place the component to be riveted 10; the riveting module 200 is slidably arranged on the bracket 100 in the first direction, and the riveting module 200 is opposite to the carrier 110 in the first direction. The riveting module 200 includes a die base 210, a heating element 220 and a riveting head 230. The riveting head 230 is arranged on one side of the die base 210 facing the carrier 110 in the first direction, and the heating element 220 is used to heat the die base 210; the temperature control module 300 is arranged on the die base 210. The temperature control module 300 includes a temperature simulation element 310, a first temperature measuring element 320 and a temperature reduction structure 330. The temperature simulation element 310 is connected to the die base 210, the first temperature measuring element 320 is used to detect the temperature of the temperature simulation element 310, and the temperature reduction structure 330 is used to reduce the temperature of the temperature simulation element 310. Wherein, the first direction can be the height direction of the hot riveting die.

[0067] When the hot riveting die is in use, the die base 210 is heated by the heating element 220 to increase the temperatures of the riveting head 230 and the temperature simulation element 310. When the temperature of the temperature simulation element 310 detected by the first temperature measuring element 320 meets the riveting requirement, the riveting module 200 is controlled to slide towards the carrier 110 in the first direction to rivet the component to be riveted 10, and the temperature reduction structure 330 is controlled to reduce the temperature of the temperature simulation element 310 to simulate the heat loss of the riveting head 230 when riveting the component to be riveted 10, so that the temperatures of the temperature simulation element 310 and the riveting head 230 are equal or close. After the riveting of the component to be riveted 10 is completed, the riveting module 200 is reset, and when the temperature of the temperature simulation element 310 meets the riveting requirement again under the heating of the heating element 220, the hot riveting die can be controlled to rivet the next round of components to be riveted 10. Under the simulation that the temperature reduction structure 330 reduces the temperature of the temperature simulation element 310 to simulate the heat loss of the riveting head 230 when riveting the component to be riveted 10, the temperature of the temperature simulation element 310 detected by the first temperature measuring element 320 is equal or close to the actual temperature of the riveting head 230, so as to accurately control the temperature of the riveting head 230, effectively reduce the temperature fluctuation range of the riveting head 230, ensure the hot riveting quality and improve the production efficiency. Wherein, the temperatures of the temperature simulation element 310 and the riveting head 230 are close, which can be understood as the temperature difference between the temperature simulation element 310 and the riveting head 230 is less than T, where T can be 5°C, 10°C, 20°C, 30°C, 40°C or 50°C.

[0068] Exemplarily, the die base 210 can be made of a metal material with a high thermal conductivity, such as copper.

[0069] Exemplarily, the materials of the riveting head 230 and the temperature simulation element 310 can be the same, such as white steel, which is wear-resistant and has a long service life.

[0070] Exemplarily, both the first temperature measuring element 320 and the temperature reduction structure 330 can be fixed on the temperature simulation element 310.

[0071] Exemplarily, the temperature control module 300 can be disposed on one side of the mold base 210 along the second direction. Wherein, the second direction can be the front-rear direction of the hot riveting mold, the first direction and the second direction are perpendicular to each other. Preferably, the temperature control module 300 is disposed on the rear side of the mold base 210.

[0072] In this embodiment, referring to Figure 2 and Figure 3 as shown, mounting holes 211 are provided on the periphery of the mold base 210, the temperature sensing member 310 is inserted into the mounting holes 211, and the depth of the temperature sensing member 310 inserted into the mounting holes 211 is adjustable. It can be understood that adjusting the depth of the temperature sensing member 310 inserted into the mounting holes 211, that is, adjusting the contact area between the temperature sensing member 310 and the mold base 210, that is, adjusting the heat conducted from the mold base 210 to the temperature sensing member 310, to ensure that the temperatures of the temperature sensing member 310 and the riveting head 230 are equal or close under the heating of the heating member 220, so as to indirectly control the actual working temperature of the riveting head 230.

[0073] In some embodiments, the temperature sensing member 310 is threadedly connected to the mounting hole 211, and the temperature control module 300 further includes a first screw set (not shown). The first screw set is sleeved on the temperature sensing member 310 and threadedly connected to the temperature sensing member 310, and the first screw set abuts against the periphery of the mold base 210. When it is necessary to adjust the depth of the temperature sensing member 310 inserted into the mounting hole 211, the first screw set can be loosened first, and then the temperature sensing member 310 can be screwed to facilitate adjustment.

[0074] In some embodiments, a spring pin (not shown) is provided on the mold base 210. The spring pin includes a pin seat, a pin rod inserted into the pin seat, and a spring disposed in the pin seat. The pin seat is fixed on the mold base 210, and the head of the pin rod extends into the mounting hole 211; a row of positioning grooves 2601 are provided on the temperature sensing member 310 along the direction of insertion into the mounting hole 211, and the head of the pin rod is selectively engaged with the positioning grooves 2601 to adjust the depth of the temperature sensing member 310 inserted into the mounting hole 211.

[0075] Of course, the adjustable depth of the temperature sensing member 310 inserted into the mounting hole 211 can also be realized by other structures, which are not limited in this embodiment.

[0076] Exemplarily, the first temperature measuring member 320 can be a thermocouple.

[0077] In this embodiment, continue to refer to Figure 2 and Figure 3 as shown, the cooling structure 330 includes a heat insulation joint 331, a connecting pipe 332 and a throttle valve 333.

[0078] Specifically, the temperature simulation member 310 is provided with heat dissipation holes, and the first end of the heat insulation joint 331 is communicated with the heat dissipation holes; the first end of the connecting pipe 332 is communicated with the second end of the heat insulation joint 331; the throttle valve 333 is communicated with the second end of the connecting pipe 332.

[0079] In this embodiment, the opening degree of the throttle valve 333 is adjusted to control the flow rate of the medium flowing into the connecting pipe 332, that is, to adjust the flow rate flowing from the heat insulation joint 331 into the heat dissipation holes, so as to adjust the cooling rate of the temperature simulation member 310, making the temperature of the temperature simulation member 310 equal to or close to the temperature of the riveting head 230, which is convenient for adjustment. Moreover, the heat insulation joint 331 has a relatively small thermal conductivity, which can reduce the interference with the temperature of the temperature simulation member 310 and ensure that the temperature of the temperature simulation member 310 is equal to or close to the temperature of the riveting head 230. It can be understood that each time the riveting head 230 punches and rivets the component to be riveted 10, the cooling structure 330 will deliver a certain amount of medium into the heat dissipation holes to reduce the temperature of the temperature simulation member 310. In addition, the connecting pipe 332 can extend the heat conduction from the heat insulation joint 331 to the throttle valve 333, keep the throttle valve 333 at a relatively low temperature, and extend the service life of the throttle valve 333.

[0080] Exemplarily, the medium can be a low-temperature gas.

[0081] Exemplarily, the heat insulation joint 331 can be made of a metal material with a low thermal conductivity, such as stainless steel.

[0082] Exemplarily, the connecting pipe 332 can be a high-temperature resistant pipe fitting.

[0083] Exemplarily, the connecting pipe 332 can be connected to the heat insulation joint 331 through a quick connector 334, which is convenient for connection. Among them, the quick connectors 334 can all be high-temperature resistant quick connectors 334.

[0084] Exemplarily, the heat insulation joint 331 can be connected to the heat dissipation holes by means of threaded connection. Exemplarily, the cooling structure 330 further includes a pipe joint 335 with external threads at both ends. One end of the pipe joint 335 is inserted into the heat dissipation holes and is threadedly connected to the heat dissipation holes, and the other end is inserted into the heat insulation joint 331 and is threadedly connected to the heat insulation joint 331.

[0085] In this embodiment, continue to refer to Figure 2 and Figure 3 As shown, the die base 210 is provided with a first hole 212 and a second hole 213. The first hole 212 extends along a first direction, and the riveting head 230 is inserted into the first hole 212; the riveting module 200 further includes a first fastener 250. The first fastener 250 is inserted into the second hole 213 and is threadedly connected to the second hole 213, and the first fastener 250 abuts against the circumference of the riveting head 230, so as to stably fix the riveting head 230 on the die base 210.

[0086] Exemplarily, the riveting head 230 is provided with at least one, and the riveting head 230 is arranged in one-to-one correspondence with the first fastener 250.

[0087] In this embodiment, referring to Figure 4 and Figure 5 As shown, the heating element 220 is connected with a second temperature measuring element 240, and the second temperature measuring element 240 is used to detect the temperature of the heating element 220. In this embodiment, according to the temperature of the temperature-simulating element 310 detected by the first temperature measuring element 320 and the temperature of the heating element 220 detected by the second temperature measuring element 240, controlling whether the heating element 220 heats the die base 210 can effectively reduce the temperature fluctuation range of the riveting head 230, ensure the hot riveting quality, and improve the production efficiency. Preferably, the second temperature measuring element 240 can be at the rear side of the heating element 220.

[0088] Exemplarily, the first temperature measuring element 320 is electrically connected with a first switch (not shown), the second temperature measuring element 240 is electrically connected with a second switch (not shown), and the first switch and the second switch can be connected in series in the power supply circuit of the heating element 220. Among them, according to the temperature values detected by the first temperature measuring element 320 and the second temperature measuring element 240, controlling the closing and opening of the first switch and the second switch to control whether the heating element 220 heats the die base 210. It can be understood that the working temperature value T1 of the riveting head 230 and the maximum temperature value T2 allowed by the heating element 220 are set, and by judging whether the temperature value of the temperature-simulating element 310 detected by the first temperature measuring element 320 reaches T1 and whether the temperature value of the heating element 220 detected by the second temperature measuring element 240 reaches T2, the closing and opening of the first switch and the second switch are controlled.

[0089] Exemplarily, the maximum temperature allowed by the heating element 220 is set to 400 °C, and the working temperature of the riveting head 230 is set to 180 °C. During the continuous operation of the hot riveting die, when the second temperature measuring element 240 detects that the temperature of the heating element 220 is higher than 400 °C, the second switch is disconnected to stop the power supply to the heating element 220. It can be understood that because the first switch and the second switch can be connected in series in the power supply circuit of the heating element 220, regardless of whether the temperature of the temperature-simulating element 310 detected by the first temperature measuring element 320 reaches 180 °C, the power supply to the heating element 220 will be stopped. And at this time, if the temperatures of the temperature-simulating element 310 and the riveting head 230 do not reach 180 °C, the riveting head 230 and the temperature-simulating element 310 will also quickly rise to 180 °C under the heat conducted by the heating element 220. During the continuous operation of the hot riveting die, when the first temperature measuring element 320 detects that the temperature of the temperature-simulating element 310 is higher than 180 °C, the first switch is disconnected to stop the power supply to the heating element 220, that is, regardless of whether the temperature of the heating element 220 detected by the second temperature measuring element 240 reaches 400 °C, the power supply to the heating element 220 will be stopped.

[0090] It is understandable that the heating element 220 is powered on for heating only when the second temperature measuring element 240 detects that the temperature of the heating element 220 is lower than 400° C. and the first temperature measuring element 320 detects that the temperature of the simulated temperature element 310 is lower than 180° C.

[0091] Exemplarily, the second temperature measuring element 240 may be a thermocouple.

[0092] In a feasible embodiment, the heating element 220 includes a heat conducting plate 221 and a heating core 222, and the second temperature measuring element 240 is disposed on the heat conducting plate 221. Preferably, the heat conducting plate 221 and the mold base 210 are in contact with each other on one side. The first switch and the second switch can be connected in series to the power supply circuit of the heating core 222, and the heating core 222 is powered on to generate heat, thereby increasing the temperature of the heat conducting plate 221 to heat the rivet head 230 and the simulated temperature element 310. Preferably, the heating core 222 can be inserted into the rear side of the heat conducting plate 221.

[0093] Exemplarily, the heat conducting plate 221 may be made of a metal material with high thermal conductivity, such as copper.

[0094] Exemplarily, the heating element 220 includes at least one heating core 222, for example, two heating cores 222 are arranged at intervals along the second direction. The third direction may be the left-right direction of the hot riveting mold, and the first direction, the second direction and the third direction are perpendicular to each other.

[0095] In this embodiment, refer to Figures 4 to 6 As shown, the heating element 220 is arranged on the side of the mold base 210 away from the carrier 110 along the first direction, and the riveting module 200 also includes a heat insulation board 260, a first heat insulation assembly, a heat dissipation plate 270 and a second heat insulation assembly. Specifically, the heat insulation board 260 is arranged on the side of the heating element 220 away from the mold base 210 along the first direction; the first heat insulation assembly is arranged between the heat insulation board 260 and the heating element 220, and the first heat insulation assembly includes a plurality of first heat insulation members 281; the heat dissipation plate 270 is arranged on the side of the heat insulation board 260 away from the heating element 220 along the first direction, and the heat dissipation plate 270 is slidably connected with the bracket 100 along the first direction; the second heat insulation assembly is arranged between the heat insulation board 260 and the heat dissipation board 270, and the second heat insulation assembly includes a plurality of second heat insulation members 282.

The second fastener 160 is threadedly connected to the fourth hole 112 and abuts against the periphery of the guide post 150, so that the connection of the guide post 150 is stable and reliable.
