Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a metal product stamping equipment with a quick mold changer. Background Technology

[0002] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily-use metal products, etc. With the continuous development of technology, in order to ensure the rapid development of the metal products industry, the technical requirements for metal product stamping and forming equipment are also constantly increasing.

[0003] Existing metal stamping and forming equipment still has some shortcomings in actual use:

[0004] 1. Existing metal stamping equipment mainly replaces molds by tightening nuts and bolts to install or remove them. This method makes mold replacement cumbersome and affects work efficiency.

[0005] 2. When changing the mold in existing metal stamping and forming equipment, it is necessary to move the larger mold to the bottom of the stamping and forming equipment by hoisting, and then adjust and align the nuts and bolts before installation, which is not convenient. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that the existing technology mainly uses the tightening of nuts and bolts to install or disassemble molds. This method makes mold replacement cumbersome and affects work efficiency. It requires hoisting a large mold to the bottom of the stamping equipment and then adjusting the nuts and bolts to align them before installation, which is not convenient. Therefore, this utility model proposes a metal product stamping equipment with quick mold replacement.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A metal stamping forming equipment with quick mold change capability includes a base, a lower mold placed on top of the base, an upper mold placed on top of the lower mold, a support frame fixedly installed on top of the base, a connecting plate below the support frame, two first L-shaped frames slidably connected to the top of the connecting plate, and two second L-shaped frames slidably connected to the top of the connecting plate; it also includes a driving assembly that can drive the two first L-shaped frames and the two second L-shaped frames to move towards each other; and an auxiliary assembly that can assist the movement of the lower mold and the upper mold.

[0009] In one possible design, the drive assembly includes a hollow column fixedly connected to the top of a connecting plate. A gear disk is rotatably fitted onto the outer wall of the hollow column, and a bevel gear disk is rotatably fitted onto the outer wall of the hollow column, with the gear disk and the bevel gear disk being fixedly connected. Lead screws are threaded through the two first L-shaped frames and the two second L-shaped frames. Bevel gears are fixedly fitted onto the outer walls of the four lead screws, and the bevel gears mesh with the bevel gear disks. A support plate is fixedly installed on the top of the connecting plate, and the lead screws rotatably pass through the support plate. A drive motor is fixedly connected to the top of the connecting plate, and a gear is fixedly fitted onto the outer wall of the output shaft of the drive motor, with the gear meshing with the gear disk.

[0010] In one possible design, the auxiliary component includes two grooves disposed on the top of the base, each groove having multiple auxiliary wheels rotatably connected to it via a rotating shaft, and the bottom of the lower mold having two slide rails fixedly connected to it, the slide rails extending into the grooves and moving with the assistance of the auxiliary wheels.

[0011] In one possible design, two U-shaped frames are fixedly connected to the top of the base, and columns slide through the bottom of the two first L-shaped frames, with the bottom of the columns sliding within the U-shaped frames.

[0012] In one possible design, a first trapezoidal plug is fixedly connected to the side of each of the two second L-shaped frames that are close to each other, and a second trapezoidal plug is fixedly connected to the side of each of the two columns that are close to each other.

[0013] In one possible design, the upper mold is provided with first trapezoidal slots on all four sides, and four first trapezoidal blocks are inserted into the first trapezoidal slots accordingly. The lower mold is provided with second trapezoidal slots on both sides, and two second trapezoidal blocks are inserted into the second trapezoidal slots accordingly.

[0014] In one possible design, a cylinder is fixedly mounted on the top of the support frame, and the output shaft of the cylinder passes through the hollow column and is fixedly connected to the top of the connecting plate.

[0015] In this application, during replacement, the new lower and upper molds are placed on the base. The slide rails at the bottom of the lower mold are placed on two rows of auxiliary wheels. The auxiliary wheels assist in pushing the lower and upper molds, moving them below the support frame. The drive motor is then started, and its output shaft drives the gears to rotate. The meshing of the gears and the gear disc drives the bevel gear disc to rotate, which in turn drives four bevel gears to rotate synchronously. These bevel gears then drive the lead screw to rotate, pulling the second L-shaped frame and the first L-shaped frame respectively. The second and first L-shaped frames correspondingly pull the first trapezoidal insert and the second trapezoidal insert, causing the first trapezoidal insert to insert into the first trapezoidal slot. Two columns, each driven by a first L-shaped frame, are limited to movement via a U-shaped frame, allowing the second trapezoidal insert to be inserted into the second trapezoidal slot. This effectively limits the movement of the upper and lower dies. When a metal product is placed between the upper and lower dies, the cylinder is energized, and its output shaft drives the connecting plate downwards. The connecting plate then pushes the upper die downwards for pressing. When the lower and upper dies need to be replaced, the drive motor is activated, and its output shaft rotates in the opposite direction. This causes the two first L-shaped frames and the two second L-shaped frames to move away from each other, releasing the locking mechanism on the lower and upper dies and allowing them to be pushed out from under the support frame.

[0016] Beneficial effects: In this utility model, the metal product stamping and forming equipment with quick mold replacement utilizes the threaded transmission and meshing mechanism in the drive assembly to ensure that the lower and upper molds remain stable during the stamping process, avoiding production errors caused by mold offset or loosening. This stable fixing method also improves product quality and consistency.

[0017] In this utility model, the metal product stamping and forming equipment with quick mold replacement has a relatively simple operation process. The mold can be quickly replaced and fixed simply by starting the drive motor. This simple operation method reduces the skill requirements for operators and also reduces production accidents caused by improper operation.

[0018] This invention demonstrates significant benefits in terms of replacement efficiency, mold stability, mold adaptability, ease of operation, production capacity, and convenient maintenance, providing strong support for the production of metal products. Attached Figure Description

Two first L-shaped frames 5 and two second L-shaped frames 6 are slidably connected on the connecting plate 7. In addition, the device also includes a drive assembly that can drive the two first L-shaped frames 5 and the two second L-shaped frames 6 to move towards each other, thereby achieving clamping and release of the mold. At the same time, an auxiliary assembly is also designed to assist the movement of the lower mold 17 and the upper mold 20, ensuring a smoother mold changing process.

[0026] Reference Figure 2The drive assembly includes a hollow column 9 fixedly connected to the top of the connecting plate 7.
