Description

Technical Field

[0001] The utility model relates to the field of positioning devices, and specifically relates to a floating positioning device. Background Art

[0002] Progressive stamping, also known as progressive die stamping or continuous die stamping, is a manufacturing technology in which multiple stamping processes are gradually completed through a multi-station die during the stamping process; it is suitable for mass production and can significantly improve production efficiency and material utilization rate.

[0003] Floating feeding is a commonly used feeding method in progressive stamping. It realizes the automatic and precise feeding of strip materials through a specific device. The floating feeding device can automatically feed the strip materials into the die without manual intervention, improving production efficiency and automation level.

[0004] The existing progressive stamping feeding usually uses a floating mechanism to perform multiple up-and-down floating operations on the material to achieve progressive feeding of the material. It has been found in production and observation that the position of the material will shift after floating feeding, which will reduce the accuracy of the material position during processing, and further reduce the processing accuracy of the device for the material.

[0005] Therefore, a floating positioning device is proposed for the above problems. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows: A floating positioning device described in the utility model includes a lower die; an upper die is arranged on the top of the lower die; a floating material device is installed on the top of the lower die; a pair of punching holes are opened on the top of the lower die; a pair of positioning holes are opened on the top of the lower die; a pilot pin is slidably fitted at the top of the positioning hole; the pilot pin is installed at the bottom of the upper die; a waste slot is opened on the top of the lower die. After the material is punched at the punching hole, it will be fixed by the pilot pin at the positioning hole, realizing the positioning of the material before stamping processing by the device, improving the accuracy of the material position during processing, and further improving the processing accuracy of the device for the material.

[0008] Preferably, a spring is fixedly connected to the bottom of the inner side wall of the positioning hole; a top block is fixedly connected to the end of the spring; when the material reaches the positioning hole, it will come into contact with the top block and extrude it. The top block will compress the spring and apply an elastic force to the top block and the material, so that the material will receive an additional supporting effect, improving the structural strength at the positioning hole during material processing, reducing the deformation caused by local stress concentration when the material is stamped by the upper die, enhancing the positioning and guiding effect of the positioning hole on the material, and also improving the processing accuracy of the device for the material.

[0009] Preferably, a plurality of fixing holes are formed in the top of the lower die; the fixing holes and the positioning holes are arranged correspondingly; a groove is formed in the top of the top block; a pressing block is threadedly connected to the inner side wall of the fixing hole; the pressing block and the groove are in contact with each other; the operator can rotate the pressing block into the fixing hole so that the pressing block slides along the fixing hole. When the pressing block moves, it will come into contact with the groove and extrude it, so that the pressing block will limit the height of the top block, thereby realizing the adjustment of the floating height of the material and reducing the influence of the top block on the processing height of the material.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. For the floating positioning device of the present utility model, after the material is punched in the punching hole, it will be fixed by the guiding pin at the positioning hole, realizing the positioning of the device before the stamping process of the material, improving the accuracy of the position of the material during processing, and further improving the processing precision of the device for the material.

[0012] 2. For the floating positioning device of the present utility model, the top block will support the material under the elastic force of the spring, improving the structural strength at the positioning hole during the processing of the material, reducing the deformation of the material caused by local stress concentration when the material is stamped by the upper die, enhancing the positioning and guiding effect of the positioning hole on the material, and also improving the processing precision of the device for the material.
