Description

Technical Field

[0001] This utility model belongs to the field of metal profile processing technology, and specifically relates to a metal profile clamping fixture. Background Technology

[0002] Metal profiles refer to solid straight bars of metal that have been plastically shaped and have a specific cross-sectional shape and size. Metal profiles come in a wide variety of specifications and have extensive applications, playing a crucial role in rolling production. They are primarily used in building doors and windows, curtain walls, interior and exterior decoration, and photovoltaic brackets.

[0003] Currently, when stamping and sawing metal profiles, a clamping mechanism is needed to hold the metal profiles in place before they are conveyed to the stamping and cutting mechanisms for stamping and cutting. Because there are many different specifications of metal profiles, and the existing clamping mechanisms have a relatively simple structure, they cannot be adapted to different specifications of metal profiles by changing the clamping dies, resulting in a narrow range of applications and low practicality.

[0004] Therefore, there is an urgent need for a metal profile clamping fixture to solve the above problems. Utility Model Content

[0005] To address the aforementioned deficiencies in the existing technology, this utility model provides a metal profile clamping fixture, including a frame and a clamping mechanism. The clamping mechanism includes a feeding base plate, a top plate, a lifting plate, and a lifting cylinder. The feeding base plate is positioned above the frame, with two lower pressing blocks fixed to the left and right ends of the top surface of the feeding base plate. A lower mold is positioned between the two lower pressing blocks. The top plate is located above the feeding base plate, and four support rods are fixedly connected between the top plate and the feeding base plate. The lifting plate is located between the feeding base plate and the top plate, with two upper pressing blocks fixed to the left and right ends of the bottom surface of the lifting plate. An upper mold is positioned between the two upper pressing blocks, and the upper mold and the lower mold are vertically opposite each other. The lifting cylinder is installed above the top plate, and the piston rod of the lifting cylinder passes through the top plate and is fixedly connected to the top surface of the lifting plate.

[0006] Optionally, a drive mechanism is provided on the frame, located below the clamping mechanism. The drive mechanism includes two guide rails, a servo motor, a support base, a ball screw, a nut seat, and four sliders. The two guide rails are arranged parallel to each other and fixed on the frame. The servo motor and the support base are respectively located at the front and rear ends of the guide rails. One end of the ball screw is connected to the output shaft of the servo motor, and the other end of the ball screw is rotatably connected to the support base. The ball screw passes through the nut seat, and a ball screw nut is provided at the connection between the ball screw and the nut seat. The ball screw nut is located inside the nut seat, and the top of the nut seat is fixedly connected to the bottom surface of the feeding base plate. The four sliders are arranged in pairs and slidably connected to the two guide rails respectively, and the tops of the four sliders are all fixedly connected to the bottom surface of the feeding base plate.

[0007] Optionally, two guide rods are fixed to the top surface of the lifting platform, and both guide rods extend upward through the top platform.

[0008] Optionally, a first slot is formed between each of the two upper pressing blocks and the lifting plate, and a first protrusion matching the first slot is provided at the left and right ends of the upper mold; a second slot is formed between each of the two lower pressing blocks and the feeding base plate, and a second protrusion matching the second slot is provided at the left and right ends of the lower mold.

[0009] Specifically, when installing the upper and lower molds, the first protrusion of the upper mold can be inserted into the first slot, and the second protrusion of the lower mold can be inserted into the second slot, and then fixed with bolts, which facilitates the quick disassembly and replacement of the upper and lower molds.

[0010] Optionally, the top of the lower mold is provided with several grooves, and the bottom of the upper mold is provided with several protrusions of the same number as the grooves, with the several protrusions corresponding one-to-one with the several grooves.

[0011] Specifically, the upper and lower molds have various specifications due to the different protrusions and grooves.

[0012] This utility model also includes other components that enable the normal use of a metal profile clamping fixture, all of which are conventional technical means in the art. Furthermore, any devices or components not specified in this utility model employ conventional technical means in the art, such as servo motors and lifting cylinders.

[0013] The working principle of this utility model is as follows: First, select appropriate upper and lower molds according to the specifications of the metal profile. Then, install the upper mold between two upper pressure blocks and the lower mold between two lower pressure blocks, and fix them with bolts. Next, place the metal profile into the respective grooves of the lower mold. Control the lifting cylinder to stretch the piston rod, drive the lifting plate to move down, so that the upper mold presses on the metal profile and the lower mold. Use the upper and lower molds to clamp and fix the metal profile. Then, start the servo motor to drive the ball screw to rotate, which in turn drives the nut seat to move, so that the feeding base plate moves along the guide rail towards the stamping mechanism and the cutting mechanism. Finally, the metal profile is stamped and cut.

[0014] The beneficial effects of this utility model are that, through the feeding base plate, top plate, lifting plate, lifting cylinder, upper mold and lower mold, not only is the positioning accurate, but also different clamping molds can be replaced and installed according to different specifications of metal profiles, which has a wide range of applications and strong practicality; in addition, the upper and lower molds can be disassembled and assembled quickly, which improves production efficiency.

Two guide rods 11 are fixed on the top surface of the lifting plate 4, and both guide rods 11 pass upward through the top plate 3.

[0022] A drive mechanism is installed on the frame 1, located below the clamping mechanism. The drive mechanism includes two guide rails 12, a servo motor 13, a support base 14, a ball screw 15, a nut seat 16, and four sliders 17.
