Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology. Specifically, this utility model relates to a material support height adjustable positioning plate mechanism. Background Technology

[0002] With the booming and rapid development of the automotive industry, the production frequency of stamping machines is increasing. For sheet metal with deep drawing, due to gravity, the sheet metal collapses when placed on the blank holder. When the collapse exceeds a certain degree, it will seriously affect the formability of the product and the sensitivity of the sensor. To address this issue, we need to use an adjustable positioning plate to improve the situation.

[0003] A patent specification published on March 22, 2024, with patent number 202311785551.9, discloses an embedded material support positioning plate, including a positioning plate body, a lifting block, a support mechanism, and a mold base. The "L"-shaped positioning plate body is slidably connected to the lifting block through a lifting groove, and a fixing bolt is threaded onto the positioning plate body to lock the lifting block. At the same time, a material support block is rotatably mounted on the lifting block through a connecting shaft, which facilitates the adjustment of the height of the material support block. The positioning plate body has a stepped hole, and a support rod is slidably connected in the stepped hole. A top block supporting the material support block is installed on the support rod, and a support spring is fitted on the support rod. The support spring abuts against the top block, thereby supporting the material support block. The force on the material support block can be adjusted by adjusting the height of the support spring. It is more convenient to use, occupies less space, and is more worthy of promotion and use.

[0004] In existing technologies, the positioning plate cannot be adjusted in height and position, thus failing to adapt to different usage scenarios. Utility Model Content

[0005] The present invention aims to provide a material support height adjustable positioning plate mechanism that can adapt to different application occasions.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a material support height adjustable positioning plate mechanism, including a pressure ring, a mounting plate on the pressure ring, a positioning plate on the mounting plate, a spring between the positioning plate and the pressure ring, mounting holes on the mounting plate, a pivot pin penetrating the positioning plate inside the mounting holes, the mounting holes arranged in a row, a limiting block 0 on the mounting plate located below the positioning plate, fixing holes on the mounting plate, a fixing pin connected to the limiting block 0 inside the fixing holes, and the fixing holes arranged in a row.

[0007] The pressure ring is provided with a connecting plate, and the connecting plate has a connecting hole that is connected to the spring.

[0008] The connecting holes are arranged in a row on the connecting plate, and there is more than one of them.

[0009] A gasket is provided between the positioning plate and the mounting plate.

[0010] The sides of the mounting plate are rounded.

[0011] The mounting plates are installed in pairs.

[0012] The technical advantages of this invention are as follows: When the mold is opened, the pressure ring is pushed upward by one stroke, and the plate is placed on the adjustable support positioning plate. The polyurethane is compressed, and the positioning plate is compressed through the pivot pin. The height of the support positioning plate can be adjusted up and down and the position of the spring according to the actual situation on site, so that the positioning of the plate can be quickly adjusted.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0017] Please see Figure 1 An adjustable material support height positioning plate mechanism includes a pressure ring 1, a mounting plate 2 on the pressure ring 1, a positioning plate 3 on the mounting plate 2, a spring 4 between the positioning plate 3 and the pressure ring 1, mounting holes 7 on the mounting plate 2, a pivot pin 8 penetrating the positioning plate 3 inside the mounting holes 7, the mounting holes 7 being arranged in a row, a limiting block 10 on the mounting plate 2 being located below the positioning plate 3, and fixing holes 11 on the mounting plate 2, a fixing pin 12 connected to the limiting block 10 inside the fixing holes 11, the fixing holes 11 being arranged in a row.

[0018] When the mold opens, the pressure ring 1 pushes upward by one stroke, and the plate is placed on the adjustable support positioning plate 3. The polyurethane is compressed, and the positioning plate 3 is compressed through the pivot pin 8. The height of the support positioning plate 3 can be adjusted up and down and the position of the spring 4 according to the actual situation on site, so that the positioning of the plate can be quickly adjusted. The positioning plate 3 can be set to different heights using multiple mounting holes 7 to adapt to different conditions. The maximum downward rotation angle of the positioning plate 3 is limited by the limit block 10 to avoid excessive stretching and damage. The positioning plate 3 is fixed by the fixing pin 12, and the positions of the multiple fixing holes 11 correspond one-to-one with the positions of the mounting holes 7, which facilitates the installation of the limit block 10.

[0019] The pressure ring 1 is provided with a connecting plate 5, and the connecting plate 5 is provided with a connecting hole 6 connected to the spring 4; the other end of the spring 4 is fixed on the connecting plate 5, so that when it is not under pressure, the spring 4 can be used to drive the positioning plate 3 to reset.

[0020] There are multiple connecting holes 6 arranged in a row on the connecting plate 5; this allows the position of the spring 4 to be adjusted according to actual needs, in conjunction with the positioning plate 3.

[0021] A washer 9 is provided between the positioning plate 3 and the mounting plate 2; the addition of washer 9 reduces the possibility of damage under pressure.

[0022] The sides of the mounting plate 2 are arc-shaped; the arc-shaped edges can improve the fracture resistance of the mounting plate 2 and increase the safety of equipment use.

[0023] The mounting plates are installed in pairs; this facilitates installation and provides more even support.

[0024] The technical effect of this utility model is as follows: When the mold is opened, the pressure ring 1 is pushed upward by one stroke, and the plate is placed on the adjustable material support positioning plate 3. The polyurethane is compressed, and the positioning plate 3 is compressed through the pivot pin 8. The height of the positioning plate 3 and the position of the spring 4 can be adjusted up and down according to the actual situation on site to adjust the height of the material support positioning plate 3, so that the positioning of the plate can be quickly adjusted and completed.
