DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] according to Figure 1 , 2 As shown in FIG. 3 , a local heat treatment device for steel plates is proposed in this embodiment, including a fixed frame 1 and a heating part. A movable seat 2 is arranged in the fixed frame 1. Two limit blocks 3 are arranged in front of the movable seat 2. The limit blocks 3 are fixedly connected to the movable seat 2.

[0023] Two tooth plates 4 are provided between the two limit blocks 3, the tooth plates 4 are slidably connected to the limit blocks 3, and a gear driving member for adjusting the left and right horizontal positions of the tooth plates 4 is provided between the two tooth plates 4;

[0024] The heating part includes two matching blocks 8, the front of the matching block 8 is provided with a heating wire 9, and the back of the matching block 8 is provided with a lifting box group for adjusting the height of the matching block 8. The two lifting box groups are detachably connected to the same end of the two tooth plates 4. The steel plate to be heat treated is placed between the two heating wires 9, and the lifting box group controls the height of the heating wire 9 to ensure that the heating wire 9 can fully heat the steel plate. The gear drive cooperates with the two tooth plates 4 to adjust the left and right horizontal positions of the two tooth plates 4. When the tooth plates 4 move, the heating wire 9 will also move with it. The heating wire 9 will not heat in one area all the time, which improves the uniformity of heating the steel plate surface and has high flexibility.

[0025] For the specific structure of the gear drive, please refer to the following description.

[0026] The gear driving component includes a gear 5 and a third motor 13. The gear 5 is placed between the two tooth plates 4. The gear 5 is meshed with the teeth on the outer side of the tooth plates 4. The mounting end of the third motor 13 is fixedly connected to the back of the movable seat 2. The output end of the third motor 13 is fixedly connected to the gear 5.

[0027] The working principle of the gear drive is:

[0028] The third motor 13 drives the gear 5 to rotate, and the gear 5 meshes with the teeth on the outer side of the tooth plate 4 during rotation, pushing the tooth plate 4 to move horizontally left and right. The horizontal movement directions of the two tooth plates 4 are opposite. By controlling the gear 5 to rotate back and forth, the lifting box group fixed to the tooth plate 4 will move back and forth above the plate, ensuring that the heating wire 9 on the lifting box group evenly heats the plate.

[0029] The tooth plate 4 is slidably connected with the limit block 3, and the limit block 3 limits the tooth plate 4. In order to prevent the tooth plate 4 from falling off the limit block 3 when it moves horizontally, a groove 15 is provided on the side of the limit block 3 close to the tooth plate 4. The end of the tooth plate 4 away from the gear 5 is inserted into the groove 15 and slidably connected with the groove 15. A limiting ridge 16 is provided on the inner side of the groove 15, and the limiting ridge 16 is slidably connected with the slot 17 provided on the outer side of the tooth plate 4. When the tooth plate 4 slides along the groove 15, the limiting ridge 16 fixed on the inner side of the groove 15 will also slide along the slot 17 provided on the outer side of the tooth plate 4. The limiting ridge 16 limits the tooth plate 4 by cooperating with the slot 17, and supports the horizontal sliding of the tooth plate 4 while preventing the tooth plate 4 from separating from the limit block 3.

[0030] About the lifting box set:

[0031] The lifting box group includes an adjusting seat 7, which is detachably connected to the tooth plate 4. A movable groove is provided on the front of the adjusting seat 7. A matching block 8 is inserted into the movable groove at one end close to the adjusting seat 7. The matching block 8 is slidably connected to the movable groove. A screw rod 11 is provided in the movable groove. The screw rod 11 penetrates the matching block 8. The screw 11 is threadedly connected to the matching block 8. A second motor 12 is provided on the outer side of the adjusting seat 7. The output end of the second motor 12 is fixedly connected to the screw 11.

[0032] The lifting box group uses a screw transmission to control the height of the matching block 8, that is, the screw 11 is driven to rotate by the second motor 12, and the screw 11 cooperates with the matching block 8 during rotation. When the matching block 8 moves along the rod of the screw 11, the heating wire 9 will also move with it to adjust the heating distance of the heating wire 9 to the plate.

[0033] Of course, in addition to the screw drive, other linear drive mechanisms can also be used to adjust the height of the matching block 8, which will not be explained in detail here.

[0034] In order to facilitate the staff to replace the lifting box group, a slot is provided at the lower end of the adjustment seat 7, one end of the tooth plate 4 is inserted into the slot, and a plurality of fixing bolts 14 are installed on the back of the tooth plate 4. The fixing bolts 14 pass through the tooth plate 4 and are threadedly connected with the threaded holes provided in the slot. When releasing the fixing between the adjustment seat 7 and the tooth plate 4, the fixing bolts 14 on the back of the tooth plate 4 are screwed out from the threaded holes at the lower end of the adjustment seat 7.

[0035] It is worth further explaining that the upper and lower ends of the movable seat 2 are both provided with fixed shafts, and the movable seat 2 is rotatably connected to the inner wall of the fixed frame 1 through the fixed shaft, and the outer wall of the fixed frame 1 is provided with a first motor 6, and the output end of the first motor 6 is fixedly connected to one of the fixed shafts. The fixed frame 1 is fixed on the machine platform, and the first motor 6 can control the movable seat 2 to rotate in the fixed frame 1. During the rotation of the movable seat 2, the heating part will be moved to the upper and lower parts of the plate, and the heating part will be retracted from the plate.

[0036] In a better embodiment, a heat insulation board 10 is sleeved outside the matching block 8, and the heat insulation board 10 is fixedly connected to the matching block 8. When the heating wire 9 heats the plate, the heat insulation board 10 can separate the adjustment seat 7 from the heating wire 9 to protect the lifting box assembly.

[0037] How this application works:

[0038] The steel plate to be heat treated is placed between the two heating wires 9, and the lifting box group controls the height of the heating wires 9 to ensure that the heating wires 9 can fully heat the steel plate.

[0039] The gear drive cooperates with the two tooth plates 4 to adjust the left and right horizontal positions of the two tooth plates 4. When the tooth plates 4 move, the heating wire 9 will also move with it. The heating wire 9 will not heat in one area all the time, thereby improving the uniformity of heating the steel plate surface and having high flexibility.
