[0014] It should be noted that: similar numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0015] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the product of the present application is used, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0016] The terms "first", "second", "third", and the like, are used only to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0017] The terms "parallel", "vertical", and the like, do not mean that the components must be absolutely parallel or vertical, but can be slightly inclined. For example, "parallel" only means that its direction is more parallel relative to "vertical", and does not mean that the structure must be completely parallel, but can be slightly inclined.

[0018] The terms "horizontal", "vertical", "overhanging", and the like, do not mean that the components must be absolutely horizontal, vertical, or overhanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0019] In addition, the terms "approximately", "substantially", and the like, are intended to indicate that the relevant content is not required to be absolutely accurate, but can have some deviation. For example, "approximately equal" does not only mean absolute equality, because in actual production and operation processes, it is difficult to achieve absolute "equality", and generally there is some deviation. Therefore, in addition to absolute equality, "approximately equal" also includes the above-mentioned case of having some deviation. By way of example, in other cases, unless otherwise specified, the terms "approximately", "substantially", and the like, have similar meanings as described above.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0021] Referring to Figure 1 and Figure 2The utility model provides a technical scheme: spring clip forming automatic material returning auxiliary tool, including the fixed frame 1 for with machine tool punch part fixed connection and automatic material returning mechanism of installation on the fixed frame 1, the automatic material returning mechanism includes the crossbar 2 of fixed frame 1 connection, the lower end surface of crossbar 2 is equipped with slide 3, the movable block 4 of being installed with along slide 3 to and fro movement is on slide 3, the movable block 4's lower end surface is equipped with material returning rod 5 and sliding element 6, the end of material returning rod 5 is equipped with material returning head 51, is located the right below of crossbar 2 and is located machine tool workstation still is equipped with with sliding element 6 cooperation wedge type block 7, crossbar 2 still is equipped with reset frame 8, reset frame 8 is L type, and reset frame 8's short side is equipped with reset spring 9, reset spring 9's one end is connected with reset frame 8's short side, and the other end is connected with movable block 4, and reset spring 9 is always in tensile state, the utility model discloses through the cooperation of sliding element 6 and wedge type block 7 and the joint action of reset spring 9, the up-and-down movement of machine tool punch is converted into the to-and-fro horizontal movement of movable block 4 on slide 3, thereby realizes the contact and separation of material returning head 51 and punch head, so realizes the automatic material returning of spring clip, greatly improves production efficiency, compared with artificial taking, it is more safe and reliable.

[0022] Preferably, both ends of the slide 3 are provided with adjustable limit blocks 10. The adjustable limit blocks 10 can adjust the travel distance of the movable block 4 according to the movement distance of the punch machine tool, so that it can adapt to more machine tool models and increase its application range.

[0023] Preferably, the sliding element 6 is a fixed pulley. This reduces the friction between the sliding element 6 and the wedge type block 7 and prolongs the service life of the components.

[0024] The working principle of the utility model is as follows: when the punch part of the machine tool moves downward under the operation of the control switch, the material returning tool also moves downward as a whole, at the same time, the sliding element 6 contacts the wedge type block 7 and moves downward along the inclined surface of the wedge type block 7, so that the material returning rod 5 moves forward and separates from the punch head. When the punching is completed, the punch part moves upward, and under the action of the reset spring 9, the movable block 4 returns to the initial position, at the same time, the sliding element 6 moves upward along the inclined surface of the wedge type block 7, so that the material returning head 51 contacts the punch head again and separates the finished spring clip attached to the punch head from the punch head, that is, the automatic material returning of the spring clip is completed.

[0025] The above merely describes preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concepts described herein, by the above teachings or related art or knowledge.
