Description

Technical Field

[0001] This utility model relates to a four-column hydraulic press, specifically a four-column hydraulic press for high-speed continuous stamping. Background Technology

[0002] A four-column hydraulic press is a mechanical device that uses the static pressure of hydraulic oil delivered by an oil pump to process products made of metal, plastic, rubber, wood, powder, etc. Also known as a hydraulic press, it utilizes Pascal's Law to transmit pressure through fluid. There are many types, and their applications vary widely. Based on the type of fluid used to transmit pressure, they can be broadly classified into oil presses and water presses. Water presses generate higher total pressure and are commonly used for forging and stamping. Forging water presses are further divided into die forging water presses and free forging water presses. Die forging water presses require dies, while free forging water presses do not. my country's first 10,000-ton water press was a free forging water press. A four-column hydraulic press consists of two main parts: the main unit and the control mechanism. The main unit includes hydraulic cylinders, crossbeams, columns, and a filling device. The power mechanism consists of an oil tank, a high-pressure pump, a control system, an electric motor, pressure valves, and directional valves. This hydraulic press is suitable for pressing processes of plastic materials. Processes such as powder molding, plastic molding, cold or hot extrusion metal forming, sheet metal stretching, and transverse pressing, bending, turning, and straightening are all possible. Four-column hydraulic presses have independent power mechanisms and electrical systems, and are centrally controlled via buttons. They can operate in three modes: adjustment, manual, and semi-automatic. With societal development, four-column hydraulic presses are increasingly used when materials require processing.

[0003] Four-column hydraulic presses require mold fixing during operation, necessitating a mold-locking mechanism. However, existing mold-locking mechanisms are inconvenient to assemble and disassemble, making mold removal time-consuming and labor-intensive. Therefore, existing mold-locking mechanisms cannot meet the requirements of hydraulic presses. This application presents a four-column hydraulic press for high-speed continuous stamping. Utility Model Content

[0004] The main objective of this disclosure is to provide a four-column hydraulic press for high-speed continuous stamping, so as to effectively solve the problems raised by the inventors in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A four-column hydraulic press for high-speed continuous stamping includes a base and a top seat. Four columns arranged in a rectangular array are fixedly installed between the base and the top seat, and lifting pressure plates are slidably installed on the columns. Two Z-axis guide rods symmetrically arranged are fixedly installed on the top of the base, and a stamping plate is slidably installed on the Z-axis guide rods. A compression spring is fixedly connected between the stamping plate and the base, and the compression spring is sleeved on the Z-axis guide rod. Two stamping forming heads are fixedly installed at the bottom of the stamping plate. The lifting pressure plate is located above the stamping plate, and distributed contact blocks are fixedly connected to the bottom of the lifting pressure plate. Two sets of forming molds are installed on the top of the base, and the two sets of forming molds are respectively located below the two stamping forming heads. Two hydraulic telescopic rods are embedded in the top seat, and the output ends of the hydraulic telescopic rods are fixedly connected to the lifting pressure plate.

[0007] Preferably, the molding die consists of a static molding die and a moving molding die. The static molding die is fixedly installed on the top of the base, and the moving molding die is movably installed on the top of the base. The moving molding die and the static molding die are the same size.

[0008] Preferably, the top of the base has two grooves, and each groove has a movable block that is slidably installed in a limiting manner. The two motion forming molds are respectively fixedly installed on the top of the two movable blocks, and the two movable blocks move in opposite directions.

[0009] Preferably, a control stepper motor is fixedly installed on the side of the base, a bidirectional lead screw is rotatably installed between the two grooves, and the two moving blocks are respectively threaded onto the portions of the bidirectional lead screw located in the two grooves. The output end of the control stepper motor is fixedly connected to one end of the bidirectional lead screw.

[0010] Preferably, a bracket is fixedly installed on the column, and a small electric push rod is fixedly installed on the bracket. The output end of the small electric push rod is fixedly connected to a movable stop tongue, and the movable stop tongue is slidably installed in a through hole on the column.

[0011] Preferably, a central cylinder is fixedly installed at the center of the top of the base, and a sliding rod is slidably connected inside the central cylinder. The top of the sliding rod is fixedly connected to the bottom of the lifting pressure plate, and a push block is fixedly installed on the side of the sliding rod. A contact switch is installed on the top of the central cylinder, and the contact switch is electrically connected to a small electric push rod. The contact switch is located below the push block.

[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0013] (i) In this application, the stationary forming mold and the moving forming mold are initially in contact to form a complete forming mold. The stamping material is placed in the forming mold, and the hydraulic telescopic rod works to push the lifting pressure plate downward until the distribution contact block presses against the stamping plate on the Z-axis guide rod. During the continuous downward movement of the distribution contact block, the stamping plate drives the stamping head to move downward and extend into the forming mold. The compression spring is compressed and deformed by the downward movement of the stamping plate to distribute pressure and for subsequent reset, thereby realizing the stamping of the material.

[0014] (II) In this application, during the downward movement of the lifting pressure plate, the slide bar moves into the central cylinder to maintain the stability of the stamping. The push block on the slide bar moves down accordingly and presses the contact switch, causing the small electric push rod to work. At this time, the stamping head has been inserted into the forming mold and the stamping is completed. The small electric push rod drives the movable stop tongue to move, so that it blocks the stamping plate to prevent the instantaneous rebound of the stamping plate and keep the stamping head in the forming mold, so that the product is completely stamped. At the same time, the hydraulic telescopic rod drives the lifting pressure plate to move up and reset, preparing for the next stamping.

[0015] (III) In this application, during demolding, the stepper motor is controlled to work and drive the bidirectional lead screw to rotate, so that the two moving blocks move synchronously. The moving forming mold is driven away from the stationary forming mold, so that the product can be taken out. Then the moving forming mold and the stationary forming mold are tightly fitted again, and material is added to stamp again, so that the utility model can realize continuous stamping work.

Two sets of forming molds are installed on the top of the base 1, and the two sets of forming molds are respectively located below the two stamping forming heads 10. Two hydraulic telescopic rods 13 are embedded in the top seat 2, and the output ends of the hydraulic telescopic rods 13 are fixedly connected to the lifting pressure plate 4.

[0026] Specifically, the molding die consists of a static molding die 8 and a moving molding die 9. The static molding die 8 is fixedly installed on the top of the base 1, and the moving molding die 9 is movably installed on the top of the base 1. The moving molding die 9 has the same size as the static molding die 8.

[0027] Specifically, the top of the base 1 has two grooves, and each groove has a movable block 14 that is slidably installed within it. Two motion forming molds 9 are fixedly installed on the top of the two movable blocks 14, and the two movable blocks 14 move in opposite directions.
