DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further explained in detail below by combining with the drawings and embodiments.

[0028] As Figures 1-8 shown, the utility model provides a busbar hot pressing tool, include: upper die 100, lower die 200, positive pressure block 300 and side pressure block 400. The top of lower die 200 is provided with positive pressure station 210, the side of lower die 200 is provided with the side pressure station 220 in ladder shape. Side pressure block 400 is matched with side pressure station 220, and the first inclined surface 410 of inclined setting is opened on side pressure block 400. Positive pressure block 300 is installed in positive pressure station 210. The bottom of upper die 100 is provided with the positive pressure surface matched with positive pressure block 300, and the position of the bottom of upper die 100 corresponding side pressure block 400 is fixedly connected with inclined block 110, and the second inclined surface 111 matched with first inclined surface 410 is opened on inclined block 110. When upper die 100 moves downward, under the action of first inclined surface 410 and second inclined surface 111, side pressure block 400 moves horizontally to the direction close to side pressure station 220.

[0029] In this embodiment, side pressing stations 220 are provided on both sides of the lower mold 200, with two side pressing stations 220 provided on the same side of the lower mold 200, for a total of four side pressing stations 220. The positive pressure station 210 is provided on the top of the lower mold 200. The cross-section of the positive pressure block 300 is in the shape of an inverted concave, with the protrusions on both sides of its bottom fitting perfectly with the concave positive pressure stations 210. Therefore, the present invention can process four workpieces 500 simultaneously.

[0030] The side pressure station 220 includes an adjacent vertical working surface 221 and a horizontal working surface 222. The vertical working surface 221 is adjacent to the positive pressure station 210. A first pad 230 is provided on the side of the adjacent side pressure stations 220 away from each other. A first contour surface is provided on the first pad 230. A second pad 240 is provided between adjacent side pressure stations 220. The upper surface of the second pad 240 is processed with a second contour surface. The first pad 230 and the second pad 240 are both provided on the horizontal working surface 222. The first contour surface and the second contour surface are both horizontally arranged and have equal heights. The bottom surface of the side pressure block 400 is installed on the first contour surface and the second contour surface.

[0031] In this embodiment, the first and second pads 230, 240 are mounted on the horizontal working surface 222 of the side pressing station 220. The first and second contour surfaces are both highly precise. The side pressing block 400 is positioned using the first and second contour surfaces, which improves positioning accuracy and enhances the hot pressing effect. A low recess is formed between the first and second pads 230, 240 to accommodate the workpiece 500, preventing the portion of the workpiece 500 located between the first and second pads 230, 240 from being subjected to pressure from the side pressing block 400.

[0032] The first pad 230 has an L-shaped cross section, and the side pressing block 400 is installed between the two first pads 230 on the same side. In this embodiment, the two first pads 230 on the same side play a positioning role for the side pressing block 400 and assist in the installation of the side pressing block 400.

[0033] An overpressure prevention platform 112 is fixedly connected to one side of the inclined block 110 close to the upper mold 100 , and the overpressure prevention platform 112 cooperates with the top of the side pressure block 400 .

[0034] In the embodiment, when the second inclined surface 111 of the inclined block 110 is attached to the first inclined surface 410 of the side pressing block 400, with the descending of the upper die 100, the side pressing blocks 400 on both sides of the lower die 200 move towards each other, and the vertical surface of the workpiece 500 to be processed is hot-pressed. With the descending of the upper die 100, the upper die 100 abuts on the normal pressing block 300, and the horizontal surface of the workpiece 500 to be processed is hot-pressed. With the continuous descending of the upper die 100, the anti-overpressure platform 112 abuts on the top of the side pressing block 400, at this time, due to the supporting effect of the first pad 230 and the second pad 240 on the side pressing block 400, the upper die 100 cannot continue to move downward, and the horizontal surface of the workpiece 500 to be processed is prevented from being damaged.

[0035] The top of the lower die 200 is provided with first guide holes 250 on both sides, and the bottom of the upper die 100 is fixedly connected with guide columns 120 matched with the first guide holes 250. The cooperation of the first guide holes 250 and the guide columns 120 improves the die accuracy.

[0036] As shown in Figure 7 The side wall of the normal pressing station 210 is provided with a positioning groove 211, and the workpiece 500 is matched with the positioning groove 211. The normal pressing station 210 is also provided with a positioning pin 212 for positioning the workpiece 500. In the embodiment, the workpiece 500 is composed of two bus bar arrays, and the two bus bar arrays are isolated by an insulating paper. The insulating paper is provided with a hole, and the hole of the insulating paper is sleeved on the positioning pin 212. The positioning groove 211 and the positioning pin 212 together position the workpiece 500, and good positioning effect of the workpiece 500 can be obtained.

[0037] The upper die 100 and the lower die 200 are both provided with structure grooves 130.

[0038] In the embodiment, the structure grooves 130 can reduce the weight of the upper die 100 and the lower die 200, and the structure grooves 130 can accommodate the part of the workpiece 500 that does not need to be processed.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical range disclosed by the present application can be easily thought by those skilled in the art, and should be covered within the protection scope of the present application.
