Description

Technical Field

[0001] This utility model relates to the field of stamping devices, specifically a sheet metal stamping device. Background Technology

[0002] Sheet metal is a flat, rectangular building material plate made to standard sizes, used in the construction industry, and is mostly made by forging, rolling, or casting. Sheet metal has different requirements in different environments. To meet special needs, some sheet metal requires stamping during processing. Metal stamping is a forming process that uses a press and dies to apply external force to the sheet metal, causing plastic deformation or separation, thereby obtaining a workpiece (stamped part) of the required shape and size.

[0003] After the existing metal sheets are stamped, the stamped parts are usually pushed out by electric push rods, which makes it easy to pick up the stamped parts, avoids manual handling of the stamped parts, and reduces safety accidents.

[0004] However, using electric push rods to demold stamped parts increases production costs, cannot apply force to the metal sheet more evenly, causing deformation and defects in the stamped parts during demolding, and increases the dwell time of the stamped parts in the mold, thus slowing down the production pace. Utility Model Content

[0005] The purpose of this utility model is to provide a sheet metal stamping device to solve the problems mentioned in the background art, such as the increased production cost, the inability to apply force evenly to the metal sheet, the deformation and defects of the stamped parts during the demolding process, and the longer residence time of the stamped parts in the mold, which slows down the production pace.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sheet metal stamping device, comprising: a mounting frame and a movable seat, a stamping drive device fixedly mounted on the upper surface of the mounting frame, and a linkage stamping demolding mechanism fixedly mounted on the lower surface of the stamping drive device, the linkage stamping demolding mechanism comprising: a fixed seat, a column fixedly mounted on the side surface of the fixed seat, a torsion spring sleeved on the outer circle of the column, and a locking block engaged on the outer surface of the column;

[0007] The inner surface of the movable seat is provided with a cavity and a sliding cavity. A push rod is slidably connected to the inner surface of the cavity. A second spring is sleeved on the outer surface of the push rod. A shaped pressure column is slidably connected to the inner surface of the push rod. A spherical movable rod is slidably connected to the inner surface of the sliding cavity.

[0008] Preferably, the locking block is elastically connected to the column via a torsion spring, the end face of the locking block is inclined, and the locking block is in contact with the spherical movable rod.

[0009] Preferably, the spherical movable rod is fixedly connected to the top rod, and the spherical movable rod is slidably connected to the inner surface of the sliding cavity through the top rod.

[0010] Preferably, the stamping drive device includes: a cylinder, a connecting plate fixedly installed at the output end of the cylinder, a stamping head fixedly installed on the lower surface of the connecting plate, and the inner surface of the stamping head being arranged in a semi-circular shape that fits against the outer surface of the forming pressure column.

[0011] Preferably, a stamping base is fixedly mounted on the bottom surface of the mounting bracket, and a clearance groove is provided on the inner surface of the stamping base.

[0012] Preferably, a slide rod is fixedly installed on the lower surface of the mounting bracket, the slide rod passes through the inner surface of the movable seat and is elastically connected, a first spring is sleeved at the connection between the slide rod and the movable seat, the movable seat is elastically connected to the slide rod through the first spring, and a strike rod is fixedly installed on the lower surface of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model proposes a sheet metal stamping device;

[0015] By setting up a linkage-type stamping demolding mechanism, when the stamped part is demolded after stamping, the drive mechanism drives the fixed seat to rise, causing the clamping block to squeeze the spherical movable rod to slide in the slide cavity. This causes the spherical movable rod to hit the ejector rod in the cavity, which in turn compresses the second spring and slides on the forming pressure column, thus ejecting the stamped part from the mold and completing the demolding process. Through the linkage mechanism, the stamping and demolding actions can be coordinated, reducing the dwell time of the stamped part in the mold, improving the production rhythm, and ensuring that the stamped part is evenly stressed. This ensures that the sheet metal is evenly stressed during the demolding process, reducing deformation and defects, and improving the forming quality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a sheet metal stamping device;

[0024] Example 1:

[0025] To achieve synchronized demolding of stamped parts after stamping, ensuring coordinated stamping and demolding actions, reducing the dwell time of stamped parts in the mold, and improving production speed, a column 17 is fixedly installed on the side surface of the fixed base 16. A torsion spring 18 is sleeved on the outer circle of the column 17, and a locking block 19 is engaged with the outer surface of the column 17. The inner surface of the movable base 9 has a cavity 10 and a sliding cavity 14. A push rod 11 is slidably connected to the inner surface of the cavity 10, and a second spring 12 is sleeved on the outer surface of the push rod 11. A forming pressure column 13 is slidably connected to the inner surface of the push rod 11, and a spherical movable rod 15 is slidably connected to the inner surface of the sliding cavity 14. The locking block 19 is elastically connected to the column 17 through the torsion spring 18, and the end face of the locking block 19 is beveled. The locking block 19 and the spherical movable rod 15 are connected to each other. The moving rod 15 is in contact with the ejector rod 11, and the spherical moving rod 15 is fixedly connected to the ejector rod 11. The spherical moving rod 15 is slidably connected to the inner surface of the slide cavity 14 through the ejector rod 11. The fixed seat 16 is driven to rise by the drive mechanism, so that the locking block 19 squeezes the spherical moving rod 15 to slide in the slide cavity 14, and then the spherical moving rod 15 hits the ejector rod 11 in the cavity 10, so that the ejector rod 11 compresses the second spring 12 and slides on the forming pressure column 13, thereby ejecting the stamped part on the forming pressure column 13 out of the mold, completing the demolding process of the stamped part. Through the linkage mechanism, the stamping and demolding actions can be coordinated, reducing the residence time of the stamped part in the mold, improving the production rhythm, and ensuring that the stamped part is evenly stressed, ensuring that the sheet metal is evenly stressed during the demolding process, reducing deformation and defects, and improving the forming quality.

[0026] Working Principle: When using this device, in order to achieve a linked demolding process for the stamped parts after stamping, the stamping and demolding actions can be coordinated, reducing the dwell time of the stamped parts in the mold and improving the production rhythm. The drive mechanism drives the fixed seat 16 to rise, causing the clamping block 19 to squeeze the spherical movable rod 15 to slide in the slide cavity 14. Then, the spherical movable rod 15 hits the ejector rod 11 in the cavity 10, causing the ejector rod 11 to compress the second spring 12 and slide on the forming pressure column 13. This ejects the stamped parts on the forming pressure column 13 out of the mold, completing the demolding process of the stamped parts. Through the linkage mechanism, the stamping and demolding actions can be coordinated, reducing the dwell time of the stamped parts in the mold, improving the production rhythm, and ensuring that the stamped parts are evenly stressed during the demolding process, reducing deformation and defects, and improving the forming quality.
