DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skill workers in the field without creative work belong to the scope of protection of the utility model.

[0021] Please refer to Figures 1 to 5 The utility model provides a kind of technical solutions: a heat release welding grounding device, including top cover 1, top cover 1 is adsorbed in the top opening of upper die 2, the top of upper die 2 is opened in the middle of welding powder cavity 3, the top end opening of welding powder cavity 3 is equipped with drainage passage 4, the bottom of upper die 2 is screwed with lower die 5, the bottom of lower die 5 is opened in the middle of grounding hole 6, the left and right two sides outer wall of lower die 5 is equipped with guide hole 7, lower die 5 left and right two sides outer wall is equipped with supporting mechanism 8 near guide hole 7, the bottom end outer wall of lower die 5 is equipped with adjusting mechanism 9.

[0022] In the embodiment, as Figure 4As shown, the upper fire channel 101 and the lower fire channel 201 are respectively arranged on the opposite sides of the top cover 1 and the upper die 2, and the upper fire channel 101 and the lower fire channel 201 have the same diameter and corresponding positions. It should be noted that when the operator vertically inserts the grounding electrode into the grounding hole 6 arranged at the bottom of the lower die 5, and simultaneously horizontally inserts the two grounding wires into the guide holes 7 arranged on the left and right outer walls of the lower die 5, the grounding electrode and the grounding wires on both sides are in contact with each other. Then, the operator pours the welding powder into the welding powder cavity 3 by opening the top cover 1, and closes the top cover 1 in time. At the same time, the upper fire channel 101 and the lower fire channel 201 correspond to each other and form a complete channel. At this time, the operator can put the fire powder into the upper fire channel 101 and the lower fire channel 201, and ignite the fire powder by igniting the fire powder, so that the welding powder in the welding powder cavity 3 is ignited to produce high temperature, so that the metal surfaces of the grounding electrode and the grounding wire are melted and fused together to be grounded. In actual use, the upper fire channel 101 and the lower fire channel 201 have the same diameter and corresponding positions, which can ensure that they can be perfectly spliced together when the top cover 1 is closed, forming a complete ignition channel, so that the fire powder can smoothly enter the welding powder cavity 3 to ignite the welding powder, and then the metal surfaces of the grounding electrode and the grounding wire are melted and fused together. By ensuring the integrity of the ignition channel and improving the ignition efficiency, the stability and reliability of the welding can be enhanced, and the metal connection between the grounding electrode and the grounding wire is more firm, thereby improving the performance and safety of the grounding system.

[0023] In this embodiment, as shown in FIG. 1, Figure 2 and Figure 4As shown, the contact end of the welding powder cavity 3 and the drainage channel 4 in the upper die 2 is slidably connected with a baffle 202; it should be noted that the operator can first screw the upper die 2 and the lower die 5 together, then pour the welding powder into the welding powder cavity 3, and then put the ignition powder into the upper ignition groove 101 and the lower ignition groove 201, before the welding powder in the welding powder cavity 3 is ignited by the ignition powder, the operator can first manually pull the baffle 202 between the welding powder cavity 3 and the drainage channel 4 outward from the upper die 2, at the same time, the welding powder cavity 3 and the drainage channel 4 are unblocked and connected together, at this time, the heated welding powder in the welding powder cavity 3 will fall into the drainage channel 4 and enter the grounding hole 6 and the guide hole 7, and contact the grounding electrode and the grounding wire, so that the surfaces of the two are melted and fused together to achieve grounding connection. In actual use, the baffle 202 can prevent the welding powder from entering the drainage channel 4 from the welding powder cavity 3 before the welding powder is ignited, ensuring that the welding powder enters the grounding hole 6 and the guide hole 7 only when needed, thereby avoiding the welding powder from entering between the grounding electrode and the grounding wire too early, thereby ensuring the accuracy and reliability of the welding, and during the welding process, the operator only needs to manually pull the baffle 202 when needed, so that the welding powder can easily enter the grounding hole 6 and the guide hole 7 and contact the grounding electrode and the grounding wire to achieve grounding connection, thereby reducing the operation steps and improving the work efficiency.

[0024] In this embodiment, as shown in the drawings, Figure 4 As shown, the opposite sides of the top cover 1 and the upper die 2 are provided with magnetic attraction pieces; it should be noted that before the heat welding of the grounding electrode and the grounding wire, the operator can first manually open the top cover 1, pour the welding powder into the welding powder cavity 3, and then manually pour the welding powder into the welding powder cavity 3, and then close the top cover 1 on the top opening of the upper die 2, at the moment when the top cover 1 and the upper die 2 are in contact, the magnetic attraction pieces provided on the opposite sides of the top cover 1 and the upper die 2 will be attracted to each other, thereby quickly closing the top cover 1 and the upper die 2, at this time, the upper ignition groove 101 and the lower ignition groove 201 will correspond to each other and form a complete channel, which facilitates the operator to put the ignition powder into the channel for subsequent ignition and heat welding operation. In actual use, the presence of the magnetic attraction pieces enables the top cover 1 and the upper die 2 to be quickly attracted to each other when they are in contact, thereby achieving rapid closure, which can reduce the operation time of the operator and improve the work efficiency, and the attraction force of the magnetic attraction pieces can increase the sealing between the top cover 1 and the upper die 2, preventing the welding powder from leaking during the welding process, which helps to improve the welding quality, reduce waste, and ensure the safety of the working environment. When the top cover 1 and the upper die 2 are closed, the magnetic attraction of the magnetic attraction pieces can ensure that the upper ignition groove 101 and the lower ignition groove 201 correspond to each other and form a complete channel, thereby facilitating the smooth placement of the ignition powder and the subsequent ignition and heat welding operation.

[0025] In this embodiment, as shown in Figure 1 and Figure 3 The supporting mechanism 8 includes a connecting sleeve 801, a compression spring 802 and a clamping ring 803. The connecting sleeve 801 is welded to the outer wall of the lower mold 5 near the guide hole 7. One end of the compression spring 802 is welded to the inner wall of the connecting sleeve 801, and the other end of the compression spring 802 is welded to the clamping ring 803. It should be noted that after the grounding electrode is vertically inserted into the grounding hole 6 at the bottom of the lower mold 5, the two grounding wires can be inserted horizontally into the guide holes 7 on the left and right outer walls of the lower mold 5. During this period, the grounding wires first pass through the inside of the connecting sleeve 801 and come into contact with the clamping ring 803. At this time, the grounding wires push the clamping ring 803 outward, causing the clamping ring 803 to simultaneously compress the compression spring 802 between it and the connecting sleeve 801, causing the compression spring 802 to deform due to compression, thereby expanding the gap between the clamping ring 803, allowing the entire grounding wire to pass through. After the grounding wire is inserted into the guide hole 7, the compression spring 802 simultaneously pushes the clamping ring 803 tightly against the outer wall of the grounding wire due to its rebound properties, completing the clamping and supporting of the grounding wire. In actual use, the clamping ring 803 in the supporting mechanism 8 can tightly fit the outer wall of the grounding wire and provide stable clamping force through the rebound action of the compression spring 802, preventing the grounding wire from shifting or moving during welding. The elastic contraction of the compression spring 802 allows the gap between the clamping ring 803 to be adjusted according to the size of the grounding wire, thereby adapting to grounding wires of different diameters, improving the versatility of the equipment. The tight fit of the clamping ring 803 can also prevent the grounding wire from being damaged during insertion and welding, reducing the risk of wire breakage or wear. The stable clamping provided by the supporting mechanism 8 helps to ensure uniform transmission of current during welding, improving the quality and reliability of the welding.
