In order to achieve the above purpose, the utility model adopts the following technical scheme, and the utility model comprises a bottom tire and a cover plate, and is characterized in that: a pin shaft body is arranged on the side of the bottom tire through a pin shaft bracket, a rotary pressing plate is arranged on the bottom tire, and a turned edge gap is arranged between the rotary pressing plate and the pin shaft body; the rotary pressing plate can rotate by taking the pin shaft body as a rotating center.
As a preferred scheme of the utility model, the bottom tire is provided with a pressure plate bracket, and the pin shaft body passes through the pin shaft bracket and the pressure plate bracket; the rotary pressing plate is arranged on a pin shaft body at the pressing plate support.
Furthermore, a handle is arranged at one end of the rotary pressing plate, which is positioned on the pressing plate bracket.
Furthermore, a groove body matched with the handle is arranged on the bottom tire.
As another preferable scheme of the utility model, the end part of the pin shaft body is provided with a handle, and the surface of the handle is provided with friction textures.
The utility model has the beneficial effects that: the utility model has the advantages of convenient and simple operation, accurate control, high safety, low cost and convenient maintenance. The utility model has the more prominent characteristic that the utility model can be suitable for the molding of all steel curled edge parts within a certain diameter range by replacing the pin shaft body and the pressure plate with different sizes, and does not need to make specific structural change aiming at a certain part.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the attached drawing, 1 is a bottom tire, 2 is a groove body, 3 is a pressure plate support, 4 is a handle, 5 is a pin shaft body, 6 is a rotary pressure plate, 7 is a turned edge gap, 8 is a pin shaft support, 9 is a handle, 10 is a cover plate, and 11 is a part.
Detailed Description
The utility model comprises a bottom tire 1 and a cover plate 10, and is characterized in that: a pin shaft body 5 is arranged on the side of the bottom tire 1 through a pin shaft bracket 8, a rotary pressing plate 6 is arranged on the bottom tire 1, and a turned edge gap 7 is arranged between the rotary pressing plate 6 and the pin shaft body 5; the rotary platen 6 can rotate around the pin 5 as a rotation center.
As a preferred scheme of the utility model, a pressure plate bracket 3 is arranged on the bottom tire 1, and the pin shaft body 5 passes through the pin shaft bracket 8 and the pressure plate bracket 3; the rotary pressing plate 6 is arranged on the pin shaft body 5 at the pressing plate support 3.
Furthermore, a handle 4 is arranged at one end of the rotary pressure plate 6, which is positioned at the pressure plate bracket 3.
Furthermore, a groove body 2 matched with the handle 4 is arranged on the bottom tyre 1.
In another preferred embodiment of the present invention, a handle 9 is disposed at an end of the pintle body 5, and a friction texture is disposed on a surface of the handle 9.
The bottom tire 1 and the cover plate 10 can be connected through a joint pin, and the relative position between the bottom tire 1 and the cover plate 10 is not changed after the part 11 is pressed.
The diameter of the pin shaft body 5 can be replaced randomly within a certain range, and the curling forming of different diameters is realized.
The end has the knurling processing of length 30mm about, forms friction in the line, makes things convenient for the operator to insert and extract round pin axis body 5.
The holes in the pin shaft bracket 8 and the pressing plate bracket 3 are strictly controlled by coaxiality, so that the pin shaft body 5 is completely horizontal after passing through and is parallel to the bottom die 1 of the tool.
The rotary press plate 6 is provided with a handle 4 for increasing the forming moment.
The rotary pressing plate 6 can freely rotate in an angle range of 10-180 degrees relative to the tool bottom tire on the pressing plate support 3, and the part 11 can be freely put in or taken off the tool.
In the using process, the rotary press plate 6 is turned over to a state that the outer side of the bottom tire 1 forms an included angle of 180 degrees with the bottom tire 1 (fig. 1 shows a state that the rotary press plate 6 forms an included angle of 90 degrees with the bottom tire 1), and then the part 11 is clamped between the bottom tire 1 and the cover plate 10, so that one side of the part 11 to be curled extends out of the bottom tire 1 and is lapped on the rotary press plate 6. The pin shaft body 5 with a certain diameter is penetrated through the pin shaft support 8, so that the other end of the pin shaft body 5 is inserted into the pressure plate support 3 which is coaxial with the pin shaft support 8, and the working part of the pin shaft body 5 is ensured to be in a horizontal state. And then the rotary pressing plate 6 is turned over by the handle 4 on the rotary pressing plate 6 until the rotary pressing plate 6 is turned over to the inside of the bottom tire 1 and is completely attached to the bottom tire 1. Thus, the part 11 extending out of the bottom tire 1 is overturned and extruded on the pin shaft body 5 under the driving of the rotary pressing plate 6. Finally, the pin body 5 is pulled out, the cover plate 10 is removed, the rotary press plate 6 is turned over to the outer side of the bottom tire 1 again, and the curled part 11 can be removed from the tooling.
It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the utility model.
