Description

Technical Field

[0001] The utility model belongs to the technical field of metal plate processing equipment, in particular to a metal plate bending longitudinal stamping die. Background Art

[0002] The bending and forming of metal sheets are carried out on a plate bender. The workpiece to be formed is placed on the plate bender, the brake shoe is lifted with a lifting lever, the workpiece slides to the appropriate position, and then the brake shoe is lowered onto the workpiece to be formed. The bending and forming of the metal is achieved by applying force to the bending lever on the plate bender.

[0003] Since conventional sheet metal bending equipment lacks a clamping mechanism, it needs to be operated by hand, especially during horizontal longitudinal stamping. If the metal sheet is not supported, it will fall over, which makes the operation of conventional longitudinal stamping and bending equipment more troublesome.

[0004] To this end, we proposed a metal plate bending longitudinal stamping die to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that conventional longitudinal stamping and bending equipment is troublesome to operate, and proposes a longitudinal stamping die for bending a metal plate.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A metal plate bending longitudinal stamping die comprises a hydraulic rod, the outer end of the hydraulic rod is fixedly connected to a die frame, a die is slidably mounted on the die frame, a pressing bolt is slidably inserted into the interior of the die frame, and a tension spring is connected between the die frame and the pressing bolt. The pressing bolt is pulled outward to make it slide outward against the elastic force of the tension spring, and then the metal plate is placed between the pressing bolt and the die, and then the pressing bolt is released, and the tension of the tension spring is used to act on the pressing bolt, so that the pressing bolt presses the metal plate tightly against the die, and then the hydraulic rod is driven to extend, so that the die can drive the metal plate to be pressed.

[0008] Preferably, the mold frame includes a fixed mold and a frame body, and the lower end of the fixed mold is fixedly connected to the frame body. During the pressing process, the fixed mold is used to pad the outside of the metal plate so that the fixed mold acts on the outside of the metal plate, which facilitates the bending of the metal plate.

[0009] Preferably, the mold frame further comprises a guide frame, and the guide frame is fixedly connected to the frame body. The guide frame is used to guide the die to slide, thereby increasing the stability of the die in the sliding direction.

[0010] Preferably, the pressing bolt comprises a bolt body and a pull button, and the pull button is fixedly connected to the outer end of the bolt body. The pull button is pinched and pulled outward, and the pull button overcomes the elastic force of the tension spring to drive the bolt body to slide outward, and then the metal plate is placed between the bolt body and the pressing die, and the pull button is released, so that the elastic force of the tension spring drives the bolt body to press the metal plate.

[0011] Preferably, the pressure bolt further comprises a leather block, which is fixedly embedded in the bolt body. The leather block acts on the metal plate to increase the friction force of the pressure bolt on the metal plate.

[0012] Preferably, the pressure bolt further comprises a leather rod, and the leather rod is fixedly connected to the pull button. The leather rod is used to block the outer end of the pull button to prevent the pull button from crushing the user, thereby improving the safety factor.

[0013] Preferably, the die comprises a module and a slide bar, and the module is fixedly connected to the slide bar. When the hydraulic rod is extended, the slide bar pushes the module, and the module acts on the metal plate, so that the metal plate is pressed into the fixed die for bending.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Pull the pressing bolt outward to make it slide outward to overcome the elastic force of the tension spring, then place the metal plate between the pressing bolt and the die, then release the pressing bolt, use the tension of the tension spring to act on the pressing bolt, so that the pressing bolt presses the metal plate tightly on the die, and then drive the hydraulic rod to extend, so that the die can drive the metal plate to press.

[0016] 2. When forming, use a fixed die to pad the outside of the metal plate so that the fixed die acts on the outside of the metal plate to facilitate bending the metal plate.

[0017] 3. Pinch the pull button and pull it outward. The pull button overcomes the elastic force of the tension spring to drive the bolt body to slide outward. Then place the metal plate between the bolt body and the die, release the pull button, and facilitate the elastic force of the tension spring to drive the bolt body to press the metal plate.

[0018] 4. When the hydraulic rod is extended, the module is pushed by the sliding rod, and the module acts on the metal plate, making it convenient to press the metal plate into the fixed mold for bending. BRIEF DESCRIPTION OF THE DRAWINGS
