AI Technical Summary
In stamping technology, when the material forming or flange angle is large, the parts are easily wrapped and lowered, resulting in the positioning pin being easily broken under lateral force, and the parts are difficult to pick up.
A stamped floating block positioning device is designed, including threaded positioning pins, floating blocks, molded inserts, springs, lower templates and machine-meter screws. The floating block is slidingly connected to the molded insert, and the spring is guided through the structural direction of the floating block and the lower formwork. The hanging table of the floating block is in contact with the step surface of the molded insert, and the positioning pin is screwed into the threaded hole of the floating block.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping floating block positioning device. Background Art
[0002] In the field of stamping technology, in order to improve the stability of material during forming, it is necessary to punch positioning holes in the waste area or use holes on the parts for positioning. However, sometimes the material forming or flanging angle is relatively large, which will cause the parts to easily wrap the lower mold. In this case, it is necessary to add ejector pins to the forming inserts. After adding ejector pins, the corresponding part positioning pins also need to be lengthened. However, when the part positioning pins are lengthened, the positioning pins are easily broken by the lateral force during part forming, and the parts are also easily stuck on the positioning pins, making it difficult to remove the parts. Summary of the invention
[0003] In order to overcome the deficiencies of the prior art, the utility model aims to provide a stamping float positioning device to enhance the stability of the quality of stamping parts.
[0004] To achieve the above-mentioned purpose of the invention, the utility model stamping float positioning device is mainly composed of a threaded positioning pin, a float, a forming insert, a spring, a lower template and a machine screw; the float is slidably connected to the forming insert, and a spring is installed between the float with a threaded positioning pin on the upper end and the machine screw in the lower template.
[0005] Furthermore, the floating block is inserted into the middle hole of the forming insert from below, and the hanging surface of the floating block contacts the step surface of the forming insert.
[0006] Furthermore, the forming insert is fixed on the lower template, the spring is inserted into the groove of the float block from the hole of the lower template and contacts the groove surface, the machine screw is screwed into the hole of the lower template from below, the lower surface of the spring contacts the stop surface of the machine screw, the spring lifts the float block, so that the hanging table surface of the float block contacts the step surface of the forming insert, and the float block is in a lifted state; the groove of the float block and the hole of the lower template provide guidance for the spring.
[0007] Furthermore, the positioning pin is screwed into the threaded hole of the float from above, and the upper end of the positioning pin is provided with a round hole for conveniently tightening the positioning pin in the threaded hole of the float.
[0008] Furthermore, the floating block cooperates with a ejector pin mounted on the forming insert, and the upper surface of the floating block and the ejector pin level the semi-finished part.
[0009] In practical application, the positioning hole of the semi-finished part of the previous order is aligned with the positioning pin and placed in the mold cavity for positioning. The upper surface of the floating block cooperates with the ejector pin to flatten the semi-finished part. During the stamping process, the upper die presses the semi-finished part downward, the floating block and the ejector pin are pressed to the bottom, and the semi-finished part is flanging or shaping. After the molding is completed, the upper die moves upward, the floating block and the ejector pin lift up the molded part, the hanging table of the floating block contacts the step surface of the molding insert and stops moving, the molded part is taken away manually, and a stamping cycle is completed.
[0010] Compared with the prior art, the utility model can make the locating pin as short as possible to improve the strength of the locating pin when the forming or flanging angle is relatively large and a ejector pin is needed to prevent the lower mold from wrapping, and when hole positioning is needed to improve the material forming stability, so as to prevent the parts from being stuck on the locating pin, and the floating block can also play the role of ejecting the material to prevent the parts from wrapping the lower mold.
