[0019] The working principle of the heat exchanger support bar bending device of the utility model is briefly described as follows: Figure 2 As shown, the heat exchanger includes a pipe body 991 arranged in a meandering manner, and the support bars 992 are arranged and welded on the pipe body 991. Figure 2 As shown, the end of the support bar 992 is inserted into the bending support hole 1101, the distance between the bending support holes 1101 is equal to the distance between the support bars 992, and the diameter of the bending support hole 1101 is slightly larger than the diameter of the support bar 992, so that each support bar 992 can be correspondingly inserted into the bending support hole 1101 through one-time insertion action, then, as shown, Figure 1 As shown, the pushing plate 12 is counterclockwise swung, the pushing plate 12 is placed against one side of the heat exchanger 99 and pushes the heat exchanger 99, since the bending support hole 1101 limits the swing of the support bar 992, the support bar 992 is bent at the hole opening position of the bending support hole 1101, then the pushing plate 12 is clockwise swung back to the original position, the heat exchanger 99 is taken away from the socket 11, and the support bar 992 is separated from the bending support hole 1101; then, as shown, Figure 4 As shown, the heat exchanger 99 is placed on the workbench 3, the bent support bar 992 is placed below the crimping plate 22, the width of the crimping plate 22 in the left-right direction can cover the arranged support bars 992, the cylinder 23 drives the crimping plate 22 to move downward, the crimping plate 22 is pressed on the hook part formed by the bending of each support bar 992, so that the hook part is further folded and folded, so that the originally linear support bar 992 is finally changed into a generally 180-degree folded state, so that the tip of the support bar 992 is hidden, then the cylinder 23 drives the crimping plate 22 to move upward, and the heat exchanger 99 can be taken away from the workbench 3. Since the bending position of the support bar 992 is in an arc shape, it is not easy to stab the worker. In order to make the bending mechanism 1 bend the support bar 992 more than 90° (for example, 120° to 160°), as shown, Figure 5As shown, the bending support hole 1101 should be arranged close to the edge of the socket 11, and the avoidance chamfer 1103 for avoiding the support bar 992 can be arranged. As above, by using the heat exchanger support bending device of the utility model, the end of the arranged support bar 992 can be bent and crimped once, and only two main steps are needed to bend the support bar 992 by about 180 degrees, thereby facilitating the improvement of production efficiency, and the bending device of the utility model has simple structure, easy manufacturing and low cost.
[0020] Further, as shown in Figure 1 Combined with Figure 5 As shown, the bending support hole 1101 is arranged along the up-down direction, as shown in Figure 3 As shown, the bending support hole 1101 is arranged along the front-back direction, the rear end of the socket 11 is fixedly connected with the right front end of the workbench 3, and specifically, as shown in Figure 2 As shown, the rear end of the socket 11 is welded with a support 13, and the support 13 is welded to the right front end of the workbench 3, so that the socket 11 is in a front-stretch cantilever form, and the above layout structure is beneficial to the operation of the bending device of the utility model by the worker with right-hand habit, and the action of inserting the support bar 992 into the bending support hole 1101 is also relatively simple and direct. Since the socket 11 is in a cantilever form, the workbench 3 does not hinder the insertion of the support bar 992 into the bending support hole 1101 and the swinging of the pipe body 991.
[0021] Further, as shown in Figure 2 As shown, the front end of the push plate 12 is provided with (welded) a handle 122, so that the worker can hold the handle 122 to swing the push plate 12.
[0022] Further, as shown in Figure 2 As shown, the socket 11 is screwed with a position adjusting screw 14 for supporting the pipe body 991 of the heat exchanger 99, and specifically, as shown in Figure 3 As shown, the socket 11 is formed with screw holes 1102, and the two screw holes 1102 are distributed front and back, and the position adjusting screw 14 is screwed and installed in the corresponding screw hole 1102, as shown in Figure 2 As shown, the upper end of the position adjusting screw 14 protrudes from the socket 11, so that the support bar 992 is inserted into the bending support hole 1101, and as the heat exchanger 99 moves downward, the pipe body 991 will contact the upper end of the position adjusting screw 14, at which time the upper end of the position adjusting screw 14 supports the heat exchanger 99, and rotating the position adjusting screw 14 can adjust the height position of the position adjusting screw 14, so that the depth of the support bar 992 inserted into the bending support hole 1101 can be changed, and the position of the support bar 992 bent also changes accordingly.
[0023] Further, as shown in Figure 1 And Figure 4As shown, the workbench 3 is provided with a positioning plate 24 for positioning the rear positioning bars 992, the positioning plate 24 can be installed on the workbench 3 through corresponding screws, and the positioning plate 24 is located at the rear side of the pressing and folding plate 22, so that the pressing and folding plate 22 will not touch the positioning plate 24. Then, the heat exchanger 99 is placed on the workbench 3, and then the heat exchanger 99 is moved backward, so that the above-mentioned hook portion of the bars 992 is abutted against the front side of the positioning plate 24, thereby positioning the above-mentioned hook portion. When the pressing and folding plate 22 presses the above-mentioned hook portion, the pressing and folding effect of the pressing and folding plate 22 on the above-mentioned hook portion can be stable and effective, and the worker does not need to spend a long time to place the above-mentioned hook portion in the correct position.
