Description

Technical Field

[0001] The utility model particularly relates to a hand bending jig. Background Art

[0002] When stamping and bending thin metal sheets, due to the small size of the thin metal sheets, the vibration generated by the stamping equipment during operation can easily cause the metal sheets to bump and dislocate, affecting the product yield; at the same time, the stamping force of the stamping equipment is difficult to accurately control, and the metal sheets can easily be broken due to excessive stamping force, which cannot meet production needs. Utility Model Content

[0004] A hand bending jig includes a base, on which a fixed seat and a rotating seat are respectively provided. The rotating seat is rotatably arranged on the base and can rotate relative to the fixed seat. A positioning groove is recessed on the rotating seat to position and place a workpiece, and the fixed seat partially covers the positioning groove to form a workpiece bending area.

[0005] In one embodiment, the fixing seat includes a first connecting seat and a second connecting seat, the first connecting seat is arranged on the base, the second connecting seat is detachably connected to the first connecting seat, and the second connecting seat partially covers the positioning groove to form a workpiece bending area.

[0006] In one embodiment, a third connecting seat is provided on one side of the base, a screw hole is provided through one side of the third connecting seat, and a tightening screw that can press against one side of the second connecting seat is inserted into the inner thread of the screw hole.

[0007] In one embodiment, a gripping rod is provided on one side of the rotating seat.

[0008] In one embodiment, a socket is recessed on one side of the rotating seat, and one end of the holding rod is fitted into the socket.

[0009] In one embodiment, the positioning groove is located at an end away from the fixing seat and the distance therebetween is greater than the length of the workpiece.

[0010] In one embodiment, a plurality of positioning grooves are arranged at intervals in the transverse direction, and the width of each positioning groove is not equal.

[0011] In summary, the present invention has the following beneficial effects compared to the prior art:

[0012] The utility model positions a micro-thin metal sheet in a positioning groove of a rotating seat, and manually pushes the part of one end of the micro-thin metal sheet that needs to be bent to be displaced and accommodated under the fixed seat. Then, when a user manually rotates the rotating seat, the micro-thin metal sheet in the positioning groove is driven to rotate, so that the micro-thin metal sheet rotates and presses against the fixed seat to form a manual bend at one end. The punching force is judged and adjusted by human touch to complete the stamping forming of the micro-thin metal sheet, thereby preventing damage to the metal sheet. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is one of the three-dimensional structural schematic diagrams of a hand bending jig in one embodiment of the utility model;

[0014] Figure 2 This is a schematic cross-sectional view of a hand bending jig in one embodiment of the present invention;

[0015] Figure 3 This is the second schematic diagram of the three-dimensional structure of a hand bending fixture in one embodiment of the present utility model. DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 to 3 The embodiment of the present invention shown preferably provides a hand bending jig, including a base 1, on which a fixed seat 2 and a rotating seat 3 are respectively provided. The rotating seat 3 is rotatably arranged on the base 1 and can rotate relative to the fixed seat 2. A positioning groove 4 is recessed on the rotating seat 3 for positioning a workpiece, and the fixed seat 2 partially covers the positioning groove 4 to form a workpiece bending area.

[0018] Specifically, the thin metal sheet is positioned in the positioning groove of the rotating seat, and the part of one end of the thin metal sheet that needs to be bent is manually pushed to be displaced and placed under the fixed seat. When the user manually rotates the rotating seat, the thin metal sheet in the positioning groove is driven to rotate, so that the thin metal sheet rotates and presses against the fixed seat to form a manual bend at one end. The punching force is judged and adjusted by human touch to complete the stamping forming of the thin metal sheet and prevent damage to the metal sheet.

[0019] Furthermore, the fixing base 2 includes a first connecting base 21 and a second connecting base 22. The first connecting base 21 is disposed on the base 1, and the second connecting base 22 is detachably connected to the first connecting base 21. The second connecting base 22 partially covers the positioning groove 4 to form a workpiece bending area. Specifically, the user can remove and replace the second connecting base to change the bending position of the workpiece within the positioning groove by adjusting the size of the second connecting base, thereby enhancing applicability and avoiding the disadvantage of requiring entire replacement. Only the second connecting base needs to be removed and replaced.

[0020] Furthermore, a third connecting seat 23 is provided on one side of the base 1. A screw hole 24 is provided on one side of the third connecting seat 23. The internal thread of the screw hole 24 is engaged with a tightening screw 25 that can press against one side of the second connecting seat 22. Specifically, the second connecting seat is installed and connected to the first connecting seat by the connecting screw passing through the through-hole located therein. As a result, the relative position of the second connecting seat and the first connecting seat may cause slight deviation due to the gap between the through-hole and the connecting screw, which can easily affect the subsequent bending accuracy of the thin metal sheet. To solve this problem, the tightening screw is pressed against one side of the second connecting seat to effectively eliminate the through-hole on the second connecting seat and the gap between the connecting screw and the second connecting seat.

[0021] Furthermore, a gripping rod 26 is provided on one side of the rotating seat 3. This makes it convenient for the user to drive the rotating seat to rotate by gripping the rod, and the lever principle of the gripping rod is used to achieve the effect of driving the rotating seat to rotate with less effort.

[0022] Furthermore, a socket 27 is concave on one side of the rotating seat 3, and one end of the gripping rod 26 is fitted into the socket 27. The mounting connection of the gripping rod is achieved through the socket, and preferably the gripping rod is threadedly connected to the socket.

[0023] Furthermore, the positioning groove 4 is located at an end away from the fixing base 2 and the distance therebetween is greater than the length of the workpiece, thereby facilitating the installation of the thin metal sheet in the positioning groove.

[0024] Furthermore, a plurality of positioning grooves 4 are arranged at intervals in the transverse direction, and the width of each positioning groove 4 is not equal, thereby facilitating the bending and positioning of thin metal sheets of different widths.

[0025] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
