Description

Technical Field

[0001] The present invention relates to the technical field of mold accessories, and in particular to a blank stabilizing device. Background Art

[0002] During the plate processing, it is very common to have a stable positioning of the plate. Due to the different ups and downs of the mold surface, the plate is prone to shaking when it is directly placed on the mold.

[0003] Application No. 2022107363547 discloses a positioning and supporting device for warm-formed stamping sheet metal, which positions and supports the sheet metal by setting a positioning and supporting mechanism. The positioning and supporting mechanism includes a mounting support, on which a positioning guide is installed. One side of the positioning guide is rotatably connected to a supporting block through a rotating shaft. A counterweight block is set at one end of the supporting block. The sheet metal is placed on the supporting block for positioning and supporting to achieve stable positioning.

[0004] However, the existing supporting device only supports the sheet from the bottom by the supporting block, and positions the sheet from the side, but it cannot ensure that the sheet is placed flat. In addition, during the molding and extrusion process, the sheet is pressed down to cause the supporting block to rotate. During the rotation process, the sheet is indeed limited, but it is still easy to warp and deviate during the extrusion process, thereby affecting the molding quality of the sheet. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide a blank stabilizing device to solve the problem of the blank warping and displacement.

[0006] Based on the above-mentioned purpose, the present invention provides a sheet stabilization device, including a base, which is installed on the lower mold, and a guide frame is installed on the base. A supporting mechanism is provided on one side of the guide frame, and the sheet is supported by the supporting mechanism; the supporting mechanism includes a supporting frame, which is rotatably installed on one side of the guide frame, a supporting block is provided at one end of the supporting frame, a counterweight block is provided at the other end of the supporting frame, and a pressing mechanism is provided on one side of the supporting frame, and the pressing mechanism presses and limits the sheet placed on the supporting block.

[0007] A further improvement is that the pressing mechanism includes a guide block, which is installed on one side of the support frame. A pressing block is slidably provided on the guide block, and a guide spring is connected between one end of the pressing block and the limit block.

[0008] A further improvement is that the upper and lower sides of one end of the pressing block close to the supporting block are both beveled, and a push block is installed on the guide frame to push the pressing block.

[0009] A further improvement is that the guide frame and the supporting frame are connected by bolts, a threaded hole is provided on the guide frame, the bolt passes through the supporting frame and is connected to the guide frame through the threaded hole, and the supporting frame and the bolt are rotatably arranged.

[0010] A further improvement is that a socket is provided at one end of the bolt away from the supporting frame, and an anti-dropping pin is inserted into the socket.

[0011] A further improvement is that the counterweight block is fixed to the supporting frame by screws, and the supporting block and the supporting frame are an integrated structure.

[0012] A further improvement is that a positioning groove is opened on the side of the guide frame, a positioning plate slides in the positioning groove, and a positioning spring is connected between the positioning plate and the positioning groove.

[0013] The beneficial effects of the present invention are as follows: a support frame is provided, a support block is provided at one end of the support frame, and a counterweight block is provided at the other end, so that the support frame can rotate along the bolt, and a lever is used to lift the sheet away from the sheet to ensure that the height of the sheet is consistent with the highest point of the pressing surface, thereby reducing the problem of low yield of stamping parts caused by the sheet moving and hardening during the closing process of the pressure ring due to excessive fluctuations in the pressing surface.

[0014] A pressing mechanism is set up, and a pressing block is set on one side of the supporting rack. As the supporting rack rotates, the pushing block is cooperated to retract the pressing block to facilitate the placement of the sheet. The guiding spring is used to extend the pressing block to limit the placed sheet. The sheet is positioned and placed by cooperating with the supporting block and the pressing block to prevent the sheet from warping and improve the stability of placement.

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0019] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships.

[0020] like Figure 1 、 Figure 2 As shown, this embodiment provides a blank stabilization device, comprising multiple groups arranged around the side of the lower mold insert. The device comprises a base 1 mounted on the lower mold. A guide frame 2 is mounted on the base 1. A support mechanism is provided on one side of the guide frame 2 to support the blank. The support mechanism includes a support frame 3, which is rotatably mounted on one side of the guide frame 2. A support block 4 is provided at one end of the support frame 3 to support the blank. A counterweight 5 is provided at the other end of the support frame 3. The counterweight 5 is secured to the support frame 3 via screws, and the support block 4 and support frame 3 are integrally formed. The guide frame 2 and support frame 3 are connected by bolts 10. The bolts 10 extend through the support frame 3 and are threadedly connected to the guide frame 2 through the threaded holes. The support frame 3 is rotatably arranged between the bolts 10. The support frame 3, through the bolts 10 and the counterweight 5, uses leverage to lift the blank away from the guide frame 2, ensuring that the blank is aligned with the highest point of the pressing surface.

[0021] An insertion hole is formed at one end of the bolt 10 away from the supporting frame 3, and an anti-loosening pin 11 is inserted into the insertion hole to prevent the bolt 10 from loosening after rotation by the anti-loosening pin 11.

[0022] like Figure 3 、 Figure 4As shown, a pressing mechanism is provided on one side of the support frame 3 , and the pressing mechanism presses and limits the material sheet placed on the support block 4 . The pressing mechanism includes a guide block 6, which is installed on one side of the support frame 3. A pressing block 7 is slidably provided on the guide block 6. A guide spring 8 is connected between one end of the pressing block 7 and the limit block. The upper and lower sides of the pressing block 7 close to the end of the support block 4 are both beveled. A pushing block 9 is installed on the guide frame 2. When the pushing block 9 drives the support block 4 to rotate and tilt, the pushing block 9 contacts the upper bevel of the pressing block 7 and pushes the pressing block 7, so that the pressing block 7 slides inward on the guide block 6 to facilitate the placement of the sheet on the support block 4. As the sheet is placed, the support frame 3 rotates downward, and the pushing block 9 gradually releases the push on the pressing block 7. The pressing block 7 extends out through the action of the guide spring 8 and makes the beveled edge of the lower side of the pressing block 7 gradually fit to the edge of the sheet, thereby limiting the upper side of the sheet edge and ensuring the stability of the sheet placed on the support block 4.

[0023] like Figure 5 As shown, a positioning groove 12 is provided on the side of the guide frame 2, and a positioning plate 13 slides in the positioning groove 12. A positioning spring 14 is connected between the positioning plate 13 and the positioning groove 12. The positioning plate 13 is fitted to the side of the sheet through the positioning spring 14, thereby stably positioning and guiding the sheet during the forming process, improving the positioning effect, and reducing the deviation of the sheet.

[0024] When in use, the sheet is placed on the support block 4, and the support frame 3 is flipped by the gravity of the sheet, so that the support frame 3 remains in a horizontal state to position and support the sheet, and the height of the sheet is consistent with the highest point of the pressing surface; as the support frame 3 rotates, the push block 9 releases the limit on the pressing block 7, and the guide spring 8 pushes the pressing block 7 to extend, and the pressing block 7 fits against the side of the sheet and presses the sheet from the upper side. The coordinated use of the support block 4 and the pressing block 7 ensures the stable placement of the sheet, reduces the occurrence of sheet warping, and reduces the movement of the sheet through the stable positioning of the sheet, effectively improving the product molding quality.
