For this purpose, our company has developed a stamping device for hook production, which realizes the structure of the hook 12 being bent on the body 11 by stamping. Summary of the invention

[0003] The utility model aims to provide a hook punching device for bags, which is intended to solve the problem of punching and forming the bent hook of the hook for bags.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0005] The hook punching device for luggage comprises a lower pressing assembly, an upper pressing head, a lower positioning seat and a clamping assembly; the upper pressing head is provided with an arc-shaped forming recess and a guide plane, the end of the guide plane is connected to the head end of the arc-shaped forming recess and the connection is in an arc transition; the lower positioning seat is provided with a positioning plane, the guide plane is parallel to and staggered with the positioning plane, and the staggered distance is slightly greater than the thickness of the hook; the clamping assembly comprises a clamping plate, a pushing block and a compression spring, the compression spring is located between the clamping plate and the pushing block; the upper pressing head and the pushing block are respectively provided with a first inclined surface and a second inclined surface parallel to each other; the lower pressing assembly drives the upper pressing head to move downward, the first inclined surface contacts the second inclined surface, and pushes the pushing block to move toward the lower positioning seat, so as to drive the clamping plate to move toward the lower positioning seat by squeezing the compression spring, clamp the body of the hook between the lower positioning seat and the clamping plate, and the upper end of the body enters the arc-shaped forming recess and curls.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: it also includes a fixing plate, and the side of the upper pressure head facing away from the first inclined surface has a vertical plane, and the vertical plane keeps in contact with the fixing plate.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: a positioning hole is opened on the pushing block corresponding to the compression spring, and the compression spring is partially received in the positioning hole.

[0013] To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the given embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0014] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0015] In the description of the present application, terms such as "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features.

[0016] Combined with Figures 1 - 3As shown, the present application discloses a hook punching device for luggage, comprising a lower pressing component 21, an upper pressing head 22, a lower positioning seat 23 and a clamping component 24; the upper pressing head 22 is provided with an arc-shaped forming recess 221 and a guide plane 222, the end of the guide plane 222 is connected to the head end of the arc-shaped forming recess 221 and the connection is an arc transition, this structural design can enable the upper end of the body 11 of the hook 10 to smoothly enter the arc-shaped forming recess 221 for bending and forming; the lower positioning seat 23 is provided with a positioning plane 231, the guide plane 222 is parallel to the positioning plane 231 and staggered, and the staggered distance is slightly greater than the thickness of the hook 10, thereby ensuring that after clamping the body 11, the upper pressing head can be prevented from directly pressing on the upper end of the body during the downward movement, thereby realizing the bending and forming of the upper end of the body. In addition, in order to ensure the stability of the main body and prevent it from tipping over during the stamping and bending process, the clamping assembly 24 in this embodiment preferably includes a clamping plate 24a, a pushing block 24b and a compression spring 24c, wherein the compression spring 24c is located between the clamping plate 24a and the pushing block 24b; the upper pressure head 22 and the pushing block 24b are respectively provided with a first inclined surface 223 and a second inclined surface 241 which are parallel to each other; the lower pressure assembly 21 drives the upper pressure head 22 to move downward, the first inclined surface 223 contacts the second inclined surface 241, and pushes the pushing block 24b to move toward the lower positioning seat 23, so as to drive the clamping plate 24a to move toward the lower positioning seat 23 by squeezing the compression spring 24c, so as to clamp the main body 11 of the hook 10 between the lower positioning seat 23 and the clamping plate 24a, and the upper end of the main body 11 enters the arc-shaped forming recess 221 and curls. As a result, the upper pressure head is driven downward by the downward pressure assembly, and the upper pressure head and the first inclined surface and the second inclined surface of the pushing block are contacted and squeezed, thereby driving the pushing block to move to the lower positioning seat, and then pushing the compression spring and the clamping plate to move to the lower positioning seat, and the main body of the hook is clamped between the clamping plate and the lower positioning seat by the clamping plate. At the same time, the upper end of the main body enters the arc-shaped forming recess of the upper pressure head along the guiding plane, and is subjected to the downward pressure and the guidance of the arc surface, so that the upper end of the main body is further bent into a hook as the upper pressure head moves downward, thereby realizing the hook forming of the hook. Of course, it should be noted that by adaptively adjusting the height and inclination of the first bevel and the second bevel, and adaptively adjusting the position and relative height of the arc-shaped molding concave, the first bevel and the second bevel contact and push the clamping plate to clamp the main body 11, and further push the pushing block to move, thereby compressing the compression spring and further tightening the clamping plate, so that the clamping plate further clamps the main body, thereby ensuring that the main body 11 has sufficient clamping force to ensure its sufficient stability, the upper end of the main body begins to enter the arc-shaped molding concave from the guide plane to achieve molding, so that the molding yield can be reliably guaranteed.In addition, considering that there may be interference and collision between the upper end bending of the body and the lower positioning seat 23 during the forming process, in this embodiment, it is preferred that an avoidance recess 232 is provided on the upper end surface of the lower positioning seat 23, and the avoidance recess 232 is located directly below the arc-shaped forming recess 221, so that it can be completely avoided during the bending process.

[0017] In addition, since a reaction force will be generated on the upper pressure head when the first inclined surface and the second inclined surface come into contact and the clamping plate clamps the body, in order to ensure its stability, this embodiment further includes a fixing plate 25. The surface of the upper pressure head 22 facing away from the first inclined surface 223 has a vertical plane, and the vertical plane remains in contact with the fixing plate 25, so that through the limitation and support of the fixing plate 25, the operation accuracy and stability of the upper pressure head are improved.

[0018] Of course, in order to ensure that the compression spring 24c can be positioned at the current position during operation and avoid popping out during compression deformation, in this embodiment, it is preferred that a positioning hole corresponding to the compression spring 24c is provided on the pushing block 24b, and a part of the compression spring 24c is received in the positioning hole. In addition, it can also be considered that the compression spring adopts a pagoda-shaped structure. By providing a threaded hole at the contact position between the clamping plate and the small end of the pagoda-shaped compression spring, a pressing screw is inserted from the large end to the small end of the pagoda-shaped compression spring and tightened in the threaded hole. Furthermore, the large end of the pagoda-shaped compression spring is limited by the positioning hole, and the small end of the pagoda-shaped compression spring is fixedly limited by the pressing screw, so as to solve this problem.

[0019] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
