Abstract
Description

[0002] Springs are mechanical parts that work by using elasticity. They are widely used in mechanical equipment and are one of the important parts of mechanical equipment. The performance of springs affects the operating safety and service life of the equipment. Therefore, in the preparation process of springs, some special treatments need to be done to the springs based on the working conditions of the springs. For example, springs working under high temperature conditions should be subjected to heating and strong pressure treatment or creep tempering in order to prevent creep and relaxation and improve fatigue strength. These two treatment methods generally keep the springs warm at a certain temperature (usually higher than room temperature) and a certain axial pressure (i.e., the springs are compressed along the axial direction).
[0003] In the spring hot pressing process, the convenience and efficiency of spring pressing are one of the main factors affecting the hot pressing efficiency. Therefore, those skilled in the art continue to devote themselves to the research and development of tooling that can improve the convenience and efficiency of pressing. Utility Model Content

[0023] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.
[0024] Combination Figures 1 to 3As shown, the hot pressing tooling for the spring of this embodiment mainly includes: a base 1, a first clamping mechanism 2, a second clamping mechanism 3, a first clamping mechanism 5, a second clamping mechanism 6 and a driving mechanism 4. Among them, the first clamping mechanism 2 and the driving mechanism 4 are directly mounted on the base 1, the first clamping mechanism 2 is used to clamp the first clamping mechanism 5, and the second clamping mechanism 3 is mounted on the output shaft of the driving mechanism 4 to clamp the second clamping mechanism 6. The first clamping mechanism 5 includes a plurality of positioning posts 51 for the spring to penetrate, and correspondingly, the second clamping mechanism 6 includes a plurality of positioning holes 621 for accommodating the spring, and the plurality of positioning holes 621 correspond to the plurality of positioning posts 51 one by one. When the second clamping mechanism 6 is driven by the driving mechanism 4 to be assembled on the first clamping mechanism 5, that is, when the plurality of positioning posts 51 penetrate the plurality of positioning holes 621 one by one and no longer move further, the first clamping mechanism 5 and the second clamping mechanism 6 are fixedly connected by the fastener 7.
[0025] like Figure 1 and Figure 3 As shown, the driving mechanism 4 of this embodiment includes a first cylinder 41 and a guide rail 42, which are mounted on the base 1. The second clamping mechanism 3 is mounted on the output shaft of the first cylinder 41 and is slidably connected to the guide rail 42.
[0026] like Figure 2 As shown, the first clamping mechanism 2 of this embodiment mainly includes: a first base plate 21, a first stopper 22, a second cylinder 23, a third cylinder 24, a first clamp 25 and a second clamp 26. Among them, the first base plate 21 is fixed on the base 1, and is used to position the first clamping mechanism 5 in the Z direction when clamping it; the first stopper 22 is installed on the first base plate 21, and its side facing the second clamping mechanism 3 is used for the first clamping mechanism 5 to abut against; the second cylinder 23 and the third cylinder 24 are respectively installed on both sides of the first stopper 22, the first clamp 25 is installed on the output shaft of the second cylinder 23, and the second clamp 26 is installed on the output shaft of the third cylinder 24. The first clamp 25 and the second clamp 26 are used to fix (clamp) the first clamp 5 on the first stopper 22. When it is necessary to clamp the first clamping mechanism 5, the clamping mechanism is placed on the first base plate 21, and the second cylinder 23 and the third cylinder 24 respectively drive the clamps on their respective output shafts to clamp the first clamping mechanism 5 on the first stopper 22. When it is necessary to release the first clamping mechanism 5, the second cylinder 23 and the third cylinder 24 respectively drive the corresponding clamps to leave the surface of the first clamping mechanism 5.
[0027] like Figure 3As shown, the second clamping mechanism 3 of this embodiment includes a second base plate 31, a second stopper 32, a fourth cylinder 33, a fifth cylinder 34, a third clamp 35 and a fourth clamp 36. The second base plate 31 is used for sliding connection with the guide rail 42; the second stopper 32 is arranged on the second base plate 31 and connected to the output shaft of the first cylinder 41, and the side thereof facing the first clamping mechanism 2 is used for the second clamping mechanism 6 to abut against; the fourth cylinder 33 and the fifth cylinder 34 are respectively arranged on both sides of the second stopper 32, the third clamp 35 is installed on the output shaft of the fourth cylinder 33, the fourth clamp 36 is installed on the output shaft of the fifth cylinder 34, and the third clamp 35 and the fourth clamp 36 are used to fix the second clamping mechanism 6 on the second stopper 32. The clamping and releasing process of the second clamping mechanism 3 is substantially the same as that of the first clamping mechanism 2.
[0028] like Figure 2 As shown, the first clamping mechanism 5 further includes a first mounting plate 52 and a first bearing plate 53. The first mounting plate 52 is used to abut against the first stopper 22 of the first clamping mechanism 2, the first bearing plate 53 is mounted on the first mounting plate 52, and the plurality of positioning posts 51 are disposed on the first bearing plate 53 and fixedly connected to the first bearing plate 53. Figure 3 As shown, the second clamping mechanism 6 includes a second mounting plate 61 and a second bearing plate 62. The second mounting plate 61 is used to abut against the second stopper 32 of the second clamping mechanism 3, and the second bearing plate 62 is mounted on the second mounting plate 61. The above-mentioned multiple positioning holes 621 are formed on the second bearing plate 62. Further, the fastener 7 of this embodiment includes a bolt 71 and a nut 72. Among them, the head of the bolt 71 is fixedly mounted on the second mounting plate 61, and its rod passes through the second bearing plate 62 and extends toward the first clamping mechanism 5. When the multiple positioning columns 51 on the first bearing plate 53 penetrate the spring in the positioning hole 621 on the second bearing plate 62, the bolt 71 can sequentially penetrate the first bearing plate 53 and the first mounting plate 52 to connect with the nut 72. Of course, the first stopper 22 abutting against the first mounting plate 52 is provided with a hole or slot for avoiding the bolt 71.
[0029] In summary, the method of using the hot pressing tooling for the spring of the present embodiment is as follows: the second cylinder 23 and the third cylinder 24 of the first clamping mechanism 2 respectively drive the corresponding clamps to open, and the fourth cylinder 33 and the fifth cylinder 34 of the second clamping mechanism 3 respectively drive the corresponding clamps to open; the first clamping mechanism 5 is placed on the first base plate 21, and the second clamping mechanism 6 is placed on the second base plate 31, and the two are clamped on the corresponding stopper by the corresponding clamps; the spring to be clamped is placed in the positioning hole 621 of the second bearing plate 62 (or the spring to be clamped is sleeved on the positioning column 51 on the first bearing plate 53), and then the first cylinder 41 drives the fourth cylinder 33 and the fifth cylinder 34 of the second clamping mechanism 3 to open. The second clamping mechanism 6 moves toward the first clamping mechanism 5; after the bolt 71 penetrates the first mounting plate 52 and the output shaft of the first cylinder 41 stops moving, the first clamping mechanism 5 and the second clamping mechanism 6 are locked with the nut 72, and then the first clamping mechanism 2 and the second clamping mechanism 3 respectively loosen the corresponding clamping mechanisms, and then the first clamping mechanism 5 and the second clamping mechanism 6 that are locked into one are transferred to the heating furnace; after the heating is completed, the integrated first clamping mechanism 5 and the second clamping mechanism 6 are taken out and the nut 72 is loosened, the spring is removed, and then the first clamping mechanism 5 and the second clamping mechanism 6 are respectively installed on the corresponding clamping mechanisms.

The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
