Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot press technology, specifically a heating component for a hot press. Background Technology
[0002] A hot press is used when soldering workpieces. Solder flux is placed on the workpiece beforehand. The heating element of the hot press moves downward to heat the flux to a temperature sufficient to melt and flow the solder. After cooling, the flux solidifies, forming a permanent electromechanical connection between the part and the solder.
[0003] The heating components of existing hot presses heat the heating head to a temperature sufficient to melt the solder during soldering. After soldering is completed, the heating head is stopped. However, the placement of the workpiece and the solder requires time, during which the heating head cools down rapidly. When soldering again, it needs to be reheated, which is time-consuming and the temperature is not easy to control. Different solders require different heating temperatures, which can easily lead to weak solder joints. Utility Model Content
[0004] The purpose of this invention is to provide a heating component for a hot press to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating assembly for a hot press, comprising a heating head, a fixed base fixedly connected to the upper end of the heating head, a fixed cylinder and a heating cylinder fixedly connected to the upper end of the fixed base, the heating cylinder being located inside the fixed cylinder, the heating cylinder and the fixed cylinder being coaxial, and the heating cylinder being used for heat preservation and heating of the heating head;
[0006] An insulation sleeve is fitted around the outer side of the heating cylinder. An adjustment column for controlling the temperature of the heating head is fixedly connected to the upper inner wall of the insulation sleeve. At least two heating rings are fixedly connected in the middle of the adjustment column. A preheating ring for preheating and heat preservation of the heating head is provided at the lower end of the heating ring. At least two conductive contacts are fixedly connected to the right inner wall of the fixed cylinder.
[0007] At least four heat-conducting plates are fixedly connected to the inner wall of the fixed cylinder, and two sets of auxiliary plates are fixedly connected between the heat-conducting plates and the inner wall of the heating cylinder.
[0008] Preferably, the preheating ring and the adjusting column are fixedly connected, the preheating ring is always against the side wall of the heat-conducting plate, and the heating ring is away from or against the heat-conducting plate.
[0009] Preferably, the number of heating rings and conductive contacts is the same, and heating rings at different positions and conductive contacts at different positions are interconnected. A conductive plate is fixedly connected to the outer wall of the insulation sleeve.
[0010] Preferably, a blocking ring is fixedly connected to the inner wall of the fixed cylinder. The blocking ring is an elastic rubber ring, and the inner wall of the blocking ring abuts against the outer wall of the insulation sleeve.
[0011] Preferably, the two ends of the heat-conducting plate are inclined, and the middle of the heat-conducting plate is vertical.
[0012] Preferably, the auxiliary plate has an arc-shaped structure, the two sets of auxiliary plates are arranged in opposite directions, each set of auxiliary plates has at least three auxiliary plates, and both the auxiliary plates and the heat-conducting plate are copper plates.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: a preheating ring is set in the component, which continuously heats the heating head, keeping it at a certain temperature, reducing the heating time during the welding process. Furthermore, the heated head softens the solder when in contact with the workpiece and solder, preventing solder from falling off due to compression. By changing the height of the insulation sleeve, different numbers of heating rings and heat-conducting plates can be connected, thereby precisely controlling the heating temperature of the heating head to adapt to different types of solder, making the hot press more adaptable.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0020] Please see Figure 1-4This utility model provides a technical solution: a heating assembly for a hot press, including a heating head 1, a fixed base 2 fixedly connected to the upper end of the heating head 1, a fixed cylinder 4 and a heating cylinder 3 fixedly connected to the upper end of the fixed base 2, the heating cylinder 3 being located inside the fixed cylinder 4, the heating cylinder 3 and the fixed cylinder 4 being coaxial, the heating cylinder 3 being used for heat preservation and heating of the heating head 1, an insulation sleeve 5 being sleeved on the outer side of the heating cylinder 3, an adjusting column 6 for controlling the temperature of the heating head 1 being fixedly connected to the upper inner wall of the insulation sleeve 5, and a fixed connection in the middle of the adjusting column 6. There are at least two heating rings 11. The lower end of the heating ring 11 is provided with a preheating ring 10 for preheating and heat preservation of the heating head 1. At least two conductive contacts 8 are fixedly connected to the inner wall of the right side of the fixed cylinder 4.

The preheating ring 10 is always against the side wall of the heat-conducting plate 12, and the heating ring 11 is away from or against the heat-conducting plate 12. The preheating ring 10 works continuously to preheat and keep the heating head 1 warm, so as to avoid the heating head 1 being too cold and reduce the heating time during the welding process.
[0022] The heating rings 11 and conductive contacts 8 are the same number, and the heating rings 11 and conductive contacts 8 at different positions are connected to each other. A conductive plate 9 is fixedly connected to the outer wall of the insulation sleeve 5. During the heating process, the insulation sleeve 5 moves downward, thereby pressing the heating rings 11 against the heat-conducting plate 12. At the same time, the conductive plate 9 presses against the conductive contacts 8 at different positions, energizing the heating rings 11 that are pressed against the heat-conducting plate 12 to heat them, thus precisely controlling the heating temperature.
[0023] A blocking ring 7 is fixedly connected to the inner wall of the fixed cylinder 4. The blocking ring 7 is an elastic rubber ring. The inner wall of the blocking ring 7 abuts against the outer wall of the insulation sleeve 5. The insulation sleeve 5 and the blocking ring 7 work together to keep the heating cylinder 3 warm and reduce heat loss.
[0024] The two ends of the heat-conducting plate 12 are inclined, and the middle of the heat-conducting plate 12 is vertical. The auxiliary plate 13 has an arc-shaped structure. Two sets of auxiliary plates 13 are arranged opposite to each other. Each set of auxiliary plates 13 has at least three auxiliary plates 13. Both the auxiliary plates 13 and the heat-conducting plate 12 are made of copper plates. The auxiliary plates 13 and the heat-conducting plate 12 cooperate with each other to ensure that the heat-conducting plate 12 is in close contact with the preheating ring 10 and the heating ring 11, thus ensuring the transfer of heat.
