Description

Technical Field

[0001] This utility model belongs to the technical field of metal profile processing equipment, and specifically relates to a tooling fixture for cutting metal profiles. 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 sawing metal profiles, the profiles need to be clamped and positioned before cutting. Because there are many different specifications of metal profiles, and the existing tooling fixtures have relatively simple and fixed mold structures, they can only process one type of metal profile, resulting in a narrow range of applications and low practicality.

[0004] Therefore, there is an urgent need for a tooling fixture for cutting metal profiles. Utility Model Content

[0005] To address the aforementioned deficiencies in the existing technology, this utility model provides a tooling fixture for cutting metal profiles, comprising a fixture body and a frame. The fixture body includes a base, a top plate, a mounting plate, and a lifting cylinder. The base is fixed to the frame and has four lower pressing blocks arranged in pairs with a back-to-back spacing. A lower mold is provided between the two lower pressing blocks in each pair. The top plate is located above the base, and four support rods are fixedly connected between the top plate and the base. The mounting plate is located between the top plate and the base. Two upper pressing blocks are provided at the left and right ends of the bottom of the mounting plate, and two upper pressure plates are provided between the two upper pressing blocks with a back-to-back spacing. The two upper pressure plates correspond one-to-one with the two lower molds. 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 mounting plate.

[0006] Optionally, a first slot is formed between each of the two upper pressure blocks and the mounting plate, and a first protrusion matching the first slot is provided at the left and right ends of the upper pressure plate; a second slot is formed between each of the two lower pressure blocks and the base, and a second protrusion matching the second slot is provided at the left and right ends of the lower mold, and a number of grooves are provided on the top of the lower mold, and the lower mold has a variety of specifications due to the different grooves.

[0007] Specifically, when installing the upper pressure plate and the lower mold, the first protrusion of the upper pressure plate 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 lower mold.

[0008] Optionally, two guide rods are fixedly connected to the top of the mounting plate, and both guide rods extend upward through the top plate.

[0009] Optionally, discharge ramps are provided on the rear sides of the two lower dies to facilitate material discharge.

[0010] Optionally, a cutting mechanism is provided in the frame. The cutting mechanism includes a drive assembly, a support plate, and a cutting motor. The drive assembly is located below the base and includes a lower baffle, a side baffle, two guide rails, a servo motor, a support base, a ball screw, a nut seat, and four sliders. The side baffle is vertically fixed to the bottom of the base, and the lower baffle is horizontally fixed to the rear side of the bottom of the side baffle. The two guide rails are arranged parallel to each other and fixed to the lower baffle. The support base and the servo motor are respectively located at the left and right 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 support plate. The four sliders are slidably connected to the two guide rails in pairs. The support plate is fixed on the top of the four sliders. The cutting motor is mounted on the support plate, and a saw blade is mounted on the output shaft of the cutting motor. The saw blade is located on the front side of the side baffle.

[0011] Optionally, the side baffle has a first slot for the output shaft of the cutting motor to pass through, and the base has a second slot for the top of the saw blade to pass through. The position of the second slot corresponds to the gap between the two lower molds, and the top of the saw blade protrudes through the second slot and is higher than the lower mold.

[0012] Specifically, a protective cover is installed above the second slot to protect against sawing.

[0013] Optionally, a waste collection ramp is provided below the saw blade to facilitate waste collection.

[0014] This invention also includes other components that enable the tooling fixture for cutting metal profiles to function properly, all of which are conventional techniques in the art. Furthermore, any devices or components not specified in this invention employ conventional techniques in the art, such as lifting cylinders, servo motors, and cutting motors.

[0015] The working principle of this utility model is as follows: First, select a suitable lower mold according to the specifications of the metal profile. Then, install the two lower molds between the two sets of lower pressure blocks and fix them with bolts. After the metal profile is sent to the designated position on the lower mold, control the lifting cylinder to stretch the piston rod, drive the mounting plate to move down, and then drive the upper pressure plate to move down until the upper pressure plate presses on the lower mold, thus fixing the metal profile. Then, start the cutting motor to drive the saw blade to rotate, and at the same time start the servo motor to drive the ball screw to rotate, which in turn drives the nut seat to move, so that the support plate moves along the guide rail toward the direction of the metal profile, and the saw blade is used to cut the metal profile.

[0016] The beneficial effects of this utility model are that, through the base, top plate, lower mold, mounting plate and lifting cylinder, not only is the positioning accurate, but also different lower molds can be replaced according to different specifications of metal profiles, making it flexible to use, widely applicable and highly practical.
