[0002] Cars are a common tool in modern life. The collision performance of cars is regarded as an important criterion for measuring the safety of a car. In order to increase collision and protection capabilities, cars generally use various structural beams throughout the car, including: A-pillars, B-pillars, front and rear beams, etc. Among them, many positions such as A-pillars, B-pillars and rear longitudinal beams will be locally softened to help improve structural performance.

[0003] There are many technologies to achieve local softening of automotive parts: zoning within the furnace, local cooling after taking out of the furnace; in-mold heating; laser softening; induction heating, etc. Different technologies have their own advantages and disadvantages.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] Embodiment 1, refer to Figure 1-10 , a local softening device for automobile hot-formed parts, in order to dissipate the heat of the heat conduction at the heated and softened end of the part, prevent the heat from affecting the part located outside the heated end through heat conduction, and prevent the structural performance of the part that does not need to be softened from being damaged, an induction heating body 1 is provided here, and the induction heating body 1 is an insertion-type induction heating device, which is heated by inserting a metal part into the heating end of the induction heating body 1, which will not be described in detail here, and a basic base 2 is provided on one side of the induction heating body 1, and a driving mechanism 3 is provided at the end of the basic base 2, and the driving mechanism 3 is a threaded screwing mechanism that uses a threaded column to rotate and drive forward, which will not be described in detail here;

[0038] The conveying mechanism 4 includes a conveying assembly 41 and a part positioning assembly 42. The conveying assembly 41 is arranged on the base 2, and the conveying end of the conveying assembly 41 is facing the heating position of the induction heating body 1. The output end of the driving mechanism 3 acts on the conveying assembly 41, so that the conveying assembly 41 can slide toward the side of the induction heating body 1. The part positioning assembly 42 is installed on the conveying assembly 41;

[0039] The shielding heat dissipation mechanism 5 includes a driving component 51, a shielding mechanism 52 and a heat dissipation component 6. The driving component 51 is arranged at the edge of the conveying end of the conveying component 41, and the shielding mechanism 52 is arranged on the side of the conveying end of the conveying component 41 facing the induction heating body 1, and the shielding mechanism 52 faces the heating part of the induction heating body 1. The part positioning component 42 and the shielding mechanism 52 are both provided with grooves for the parts to pass through. The heat dissipation component 6 is arranged in contact with the outer side of the shielding mechanism 52, and the driving component 51 acts on the heat dissipation component 6, so that the heat dissipation component 6 can move and fit the outer wall of the part passing through the groove of the shielding mechanism 52. During heating, the part passing through the shielding mechanism 52 is inserted into the interior of the induction heating body 1 to complete heating and softening. Due to the heat conduction effect, the heat will be transferred to the uninserted part of the part. At this time, the heat dissipation component 6 is in contact with the outside of the part to dissipate the heat, which helps to stabilize the material properties of the part that does not need to be softened.

[0040] The conveying assembly 41 includes a positioning track 411 and a mounting seat 412, the positioning track 411 is arranged on the basic base 2, and the bottom end of the mounting seat 412 is slidably mounted on the positioning track 411 through a slide seat, and the output end of the driving mechanism 3 is connected to the mounting seat 412, so that the driving mechanism 3 can drive the mounting seat 412 to move along the positioning track 411 toward the side of the induction heating body 1, and the shielding mechanism 52 includes an outer ring plate and a ceramic plug sleeve arranged on one side of the outer ring plate, and the ceramic plug sleeve is directly opposite to the heating end of the induction heating body 1, and the outer ring plate of the shielding mechanism 52 is arranged at the end of the mounting seat 412, so that the shielding mechanism 52 can slide on the positioning track 411 with the mounting seat 412, so that the ceramic plug sleeve of the shielding mechanism 52 is inserted into the heating end of the induction heating body 1, and the outer ring plate shields the outside of the heating end of the induction heating body 1;

[0041] The mounting seat 412 and the outer ring plate of the shielding mechanism 52 are both provided with through grooves for parts to pass through.

[0042] The heat dissipation assembly 6 includes a heat sink group 61, a heat dissipation tube group 62 and a fitting assembly 63. The heat sink groups 61 are grouped in pairs and are fitted to the outer wall of the outer ring plate of the shielding mechanism 52 in the vertical direction. The driving assembly 51 acts on the heat sink groups 61 so that the two heat sink groups 61 can slide towards each other in the vertical direction. The heat dissipation tube group 62 is arranged on the heat sink group 61, and the fitting assembly 63 is arranged between the gaps of the heat sink groups 61.

[0043] Among them, a pop-up mechanism 7 for squeezing the fitting component 63 to slide outward is provided between the gaps of the heat sink group 61, so that the fitting component 63 maintains a tendency to slide outward between the gaps of the heat sink group 61. When the part passes through the central through groove of the shielding mechanism 52, the driving component 51 can be used to drive the two heat sink groups 61 to slide towards each other and clamp on both sides of the part. At this time, under the action of the pop-up mechanism 7, the fitting component 63 and the heat sink group 61 are both in contact with both sides of the part to achieve heat conduction to the part.

[0044] Furthermore, the fitting component 63 includes a fitting slider 631, an extrusion spring 632 and a fitting heat sink 633. The fitting slider 631 is arranged to fit the gap of the heat sink group 61, and the pop-up mechanism 7 acts on the fitting slider 631. A plurality of extrusion springs 632 are arranged in parallel in a group on the side of the fitting slider 631 away from the pop-up mechanism 7. The number of fitting heat sinks 633 is the same as that of the extrusion springs 632, and the fitting heat sink 633 is arranged at the end of the extrusion spring 632. When the two heat sink groups 61 move toward each other and fit the outer wall of the part, under the action of the extrusion spring 632, the plurality of fitting heat sinks 633 respectively fit the outer wall of the part between the gaps of the heat sink group 61. Since the outer wall of the part is fluctuating, the heat sinks of the heat sink group 61 cannot completely fit the outer wall of the part. Multiple fitting heat sinks 633 can be used between the gaps to further fit the outer wall of the part, thereby forming a more complete fit and increasing the heat conduction and heat dissipation area.

[0045] Furthermore, the heat dissipation pipe group 62 includes a heat dissipation pipe 621, a guide pipe 622 and a heat exchange body 623. The heat dissipation pipe 621 vertically penetrates the heat sink group 61. The heat exchange body 623 is fixedly arranged on the mounting seat 412. One end of the guide pipe 622 is connected to the heat dissipation pipe 621, and the other end is connected to the heat exchange body 623. A liquid for heat conduction is arranged inside the guide pipe 622.

[0046] Among them, the two ends of the guide tube 622 are rotatably connected to the heat dissipation tube 621 and the heat exchange body 623 respectively, so that when the driving component 51 acts on the heat sink group 61 to slide vertically, the guide tube 622 can maintain the connection with the heat dissipation tube 621 and the heat exchange body 623.

[0047] The driving assembly 51 includes a sliding seat 511 and an electric push rod 512. The sliding seat 511 is slidably installed on the end edge of the mounting seat 412, and a guiding and anti-slip structure is provided at the connection between the mounting seat 412 and the sliding seat 511. The electric push rod 512 is vertically arranged on the sliding seat 511, and the output end of the electric push rod 512 is connected to the heat sink group 61. When the electric push rod 512 pushes the heat sink group 61 to slide down, due to the rotation restriction of the guide tube 622, the electric push rod 512 will slide along the edge of the sliding seat 511.

[0048] In this embodiment, the part to be softened is inserted into the grooves of the outer ring plate of the mounting seat 412 and the shielding mechanism 52, and the part positioning assembly 42 is used to position the part on the mounting seat 412. At this time, the driving mechanism 3 is used to drive the mounting seat 412 to slide on the positioning rail 411. At this time, the shielding mechanism 52 moves synchronously with the end of the part and is inserted into the heating end of the induction heating body 1. During the process, the two electric push rods 512 can be started to push the two heat sink groups 61 to move toward each other on the upper and lower sides of the part. The two heat sink groups 61 will fit the upper and lower sides of the part. Due to the fluctuation of the outer wall of the part, the heat sinks of the heat sink group 61 cannot completely fit the outer wall of the part. At this time, under the action of the extrusion spring 632, a plurality of fitting heat sinks 633 are between the gaps of the heat sink group 61. The outer walls of the parts are squeezed and fitted respectively, and a plurality of fitted heat sinks 633 are used to further fit the outer walls of the parts to form a complete fit, thereby increasing the heat conduction and heat dissipation area. At this time, the induction heating body 1 is used to perform induction heating and softening on the end of the inserted part, and the heat generated at the inserted end of the part will enter the uninserted part through heat conduction, and the heat exchange body 623 is started to pass the liquid inside the guide tube 622 through the heat dissipation through-tube 621 through the heat dissipation fin group 61. At this time, the heat sink group 61 and a plurality of fitted heat sinks 633 fit the uninserted part of the part to dissipate the conducted heat, thereby forming heat dissipation for the uninserted part of the part, thereby preventing the heat from affecting the structural performance of the part that does not need to be softened, thereby ensuring the softening effect while also ensuring the overall structural performance of the part.

[0049] Embodiment 2, as Figure 1-10 As shown, this embodiment is basically the same as the first embodiment. Preferably, in order to quickly and stably locate the position of the parts and facilitate the conveying of the parts into the heating end of the induction heating, a part positioning assembly 42 is provided here, including a vertical extrusion frame 421 and a horizontal extrusion frame 422. The vertical extrusion frame 421 is arranged on the upper and lower sides of the groove of the mounting seat 412, and the horizontal extrusion frame 422 is arranged on the left and right sides of the groove of the mounting seat 412, so that when the parts pass through the groove of the mounting seat 412 and the shielding mechanism 52, the parts can be extruded and positioned in opposite directions by the vertical extrusion frame 421 and the horizontal extrusion frame 422, thereby locking the parts in position on the mounting seat 412 and the shielding mechanism 52.

[0050] The four edges of the through-slot of the mounting seat 412 are provided with horizontal plates. The vertical extrusion frame 421 and the horizontal extrusion frame 422 have the same structure. The vertical extrusion frame 421 and the horizontal extrusion frame 422 both include a slide that passes through the horizontal plate and an extrusion block arranged at the end of the slide. A spring is arranged between the horizontal plate and the extrusion block, so that the slide and the extrusion block maintain a tendency to slide toward the center of the through-slot of the mounting seat 412.

[0051] The side of the extrusion block facing the groove is an arc edge, so that when the part is inserted into the groove of the mounting seat 412, the arc edge of the extrusion block can be squeezed to squeeze the vertical extrusion frame 421 and the horizontal extrusion frame 422 to slide outward.

[0052] In this embodiment, when the part to be softened is inserted into the groove of the outer ring plate of the mounting seat 412 and the shielding mechanism 52, the part will first squeeze the extrusion block part of the vertical extrusion frame 421 and the transverse extrusion frame 422, so that the vertical extrusion frame 421 and the transverse extrusion frame 422 on the four sides of the groove of the mounting seat 412 slide outward, and the part passes between the vertical extrusion frame 421 and the transverse extrusion frame 422. Under the action of the spring, the extrusion blocks of the vertical extrusion frame 421 and the transverse extrusion frame 422 will continue to squeeze the part, forming the positioning of the part in the groove of the mounting seat 412, which is convenient for the subsequent driving of the mounting seat 412 forward to drive the part to move synchronously.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
