Description

Technical Field

[0001] This invention relates to a stamping device for die-casting metal structures and its method of use, and particularly to a stamping device for die-casting metal structures and its method of use, belonging to the field of stamping technology. Background Technology

[0002] Stamping equipment for die-cast metal structures is a stamping device used for secondary processing of die-cast parts after they have been formed. It usually uses a hydraulic press or punch press to punch, trim, shape or partially form the die-cast parts through dies in order to remove excess material, correct dimensions or add functional structures to meet the precision and assembly requirements of the final product.

[0003] Existing stamping devices for die-cast metal structures can automatically unload materials after stamping by using the kinetic energy of the stamping movement to connect with a transmission mechanism, which is relatively energy-efficient. However, existing unloading devices have difficulty in adjusting the material's position during the unloading process, leading to unloading failures. Therefore, there is an urgent need to improve a stamping device for die-cast metal structures and its operating method to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping device for die-casting metal structures and its usage method, so as to solve the problem that existing stamping devices for die-casting metal structures can use the kinetic energy of the up-and-down movement of the stamping to connect the transmission mechanism to realize the automatic unloading process after stamping, which is more energy-efficient. However, in the process of unloading the stamped parts embedded in the stamping die, the existing unloading device is difficult to realize the material lifting operation according to the actual position, resulting in unloading failure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A stamping device for die-casting metal structures and its method of use include a frame, an upper stamping die, and a horizontal plate for connecting a power conversion component. The upper inner side of the frame is equipped with the upper stamping die, which is connected via a hydraulic lifter. A lower stamping die for positioning the stamped part is installed at the lower end of the upper stamping die. A power conversion component is connected to one side of the upper stamping die via the horizontal plate, and a transmission component is installed on one side of the power conversion component. The transmission component includes a telescopic rod fixed end, and a telescopic rod is installed on the inner side of one end of the fixed end. The upper end of the telescopic rod is fixedly connected to a reset assembly via a positioning component. A vertical frame is welded and fixed to the upper end of the positioning component. A storage tray for storing the air tube is installed on the upper end of the vertical frame. One end of the air tube is fixedly connected to a straight pipe. Both ends of the straight pipe are connected to the fixed end of the pneumatic telescopic rod. The fixed end of the pneumatic telescopic rod is fixedly connected to the upper end of an L-shaped plate. A vertical groove is provided on one side of the L-shaped plate. The L-shaped plate is slidably connected to a discharge plate through the vertical groove. A pull rope is fixedly connected to the other end of the L-shaped plate. A pull rope length adjustment component is installed in the middle of the pull rope.

[0007] Preferably, the stamping die includes a lower die body, with limit grooves formed on both sides of the upper end of the lower die body. The limit grooves are parallel to each other, and a stamping part is placed in the middle of the upper end of the lower die body. The stamping part is disposed between the limit grooves.

[0008] Preferably, a connector is fixedly connected to the lower end of the power conversion component. The top of the connector is not in contact with the middle of the bottom end of the power conversion component. The horizontal projection of the connector is L-shaped. The lower end of the connector is fixedly connected to the frame.

[0009] Preferably, the power conversion component includes a column housing, an air inlet is provided on one side of the column housing, a sealing cover is fixedly connected to the inner side of the upper end of the column housing, a connecting column is slidably connected to the middle of the sealing cover through a sealing ring, a piston plate is fixedly connected to the lower end of the connecting column, a one-way valve is installed inside both sides of the piston plate, and a bottom hole is provided at the bottom of the column housing.

[0010] Preferably, the angle between the connecting column and the horizontal plate is 90°, the connecting column and the horizontal plate are welded and fixed together, the column shell is connected to the fixed end of the telescopic rod through the air inlet, and the angle between the column shell and the fixed end of the telescopic rod is 90°.

[0011] Preferably, there are two telescopic rods, which are parallel to each other. One end of the telescopic rod is located inside the fixed end of the telescopic rod and is connected to the inner wall of the fixed end of the telescopic rod through a return spring. The fixed end of the telescopic rod is hollow. The end of the telescopic rod away from the fixed end of the telescopic rod is fixedly connected to an L-shaped plate.

[0012] Preferably, the reset assembly includes a reset cylinder, inside which a spring plunger rod is slidably connected via a reset spring and a sealing ring. The spring plunger rod has a through hole at one end exposed in the reset cylinder, and is connected to a pull rope through the through hole. The reset cylinder is connected to the bottom end of the trachea.

[0013] Preferably, the pull rope length adjustment assembly includes a fixed end, and an adjustment end is spirally connected to the other end of the fixed end. Both the fixed end and the adjustment end are fixedly connected to the pull rope.

[0014] Preferably, there are two pneumatic telescopic rods, which are parallel to each other. The moving end of the pneumatic telescopic rod is welded and fixed to the discharge plate. The included angle between the pneumatic telescopic rod and the discharge plate is 90°. The vertical projection of the discharge plate is U-shaped. The discharge plate is adapted to the limiting groove opened inside the stamping die.

[0015] Preferably, the following steps are included:

[0016] Step 1: Place the stamping part to be stamped in the middle of the upper part of the lower die body, and then power on the entire equipment to carry out the stamping process;

[0017] Step 2: In the initial stage of the stamping process, the upper stamping die moves down under the drive of the hydraulic lifter, and works with the lower die body to complete the stamping of the stamped part;

[0018] Step 3: After stamping is completed, the stamping die moves up and drives the connecting column to move up through the horizontal plate. During the upward movement of the connecting column, the piston plate moves up. At this time, the one-way valve is closed and continues to drive the piston plate to move up. The gas inside the column housing enters the fixed end of the telescopic rod, which in turn pushes the L-shaped plate and the discharge plate to move along the limiting groove to the lower end of the stamped part.

[0019] Step 4: The L-shaped plate continues to move. During the movement, the spring plunger rod is pulled by the pull rope, which extracts the gas inside the reset cylinder. At this time, the inside of the reset cylinder is under negative pressure, which causes the gas inside the fixed end of the pneumatic telescopic rod to flow into the reset cylinder through the air pipe. Then, the pneumatic telescopic rod retracts and drives the discharge plate to move up, lifting out the part of the stamped part that is embedded in the lower die body. The discharge plate continues to move, completing the automatic unloading of the stamped part from the stamping lower die.

[0020] This invention has at least the following beneficial effects:

[0021] 1. In this invention, by setting up a power conversion sub-component and a transmission component, after stamping is completed, the stamped part embedded in the lower die is lifted and moved by the kinetic energy of the upper die moving upward after stamping, thus realizing autonomous unloading. In actual application, the lifting position can be automatically adjusted according to the position of the stamped part, making it more applicable.

[0022] 2. In this invention, by using the rope length adjustment component, the distance between the fixed end and the adjustment end relative to the top of the rope is used to adjust the rope spacing between the L-shaped plate and the spring plunger rod, resulting in higher adjustment accuracy and more stable adjustment.

[0023] 3. In this invention, the overall design is modular, which allows for independent replacement during actual application, improving the convenience of subsequent maintenance. At the same time, during actual application, each module can be adjusted according to actual needs to suit different usage scenarios. Attached Figure Description
