Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile production equipment, and in particular to a shearing device for an aluminum profile extrusion press. Background Technology

[0002] Aluminum profile extrusion presses are the main equipment for the production of aluminum alloy tubes, bars, and profiles. Although their emergence and development have only taken a little over a century, they have undergone tremendous changes, evolving from manual hydraulic presses with a few mega-newtons to fully automatic hydraulic presses with two hundred mega-newtons. The types of aluminum profile extrusion presses have also greatly increased. The capacity and quantity of aluminum profile extrusion presses reflect the production technology level of a company. After the aluminum profile extrusion press extrudes the profiles, it is necessary to use a shearing device to shear the residual material after extrusion. Currently, shearing is mainly carried out by a shearing rod pushing a shearing blade to press against the extrusion die inlet of the extrusion press to shear the residual material of the extruded aluminum profile bar.

[0003] However, it still has some drawbacks in actual use. For example, since the shearing blade is fixed on the shearing rod, the blade will become dull after long-term use. It is troublesome, time-consuming and laborious to disassemble or replace the shearing blade, which indirectly increases the production time of aluminum profiles and reduces the efficiency. Therefore, there is an urgent need for a shearing device for aluminum profile extrusion machines to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a shearing device for an aluminum profile extrusion machine.

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

[0006] A shearing device for an aluminum profile extrusion press includes a fixed plate. Shearing blades for shortening aluminum profiles are provided at both ends of one side of the fixed plate. Extrusion ports are provided on both sides of the fixed plate. Fixing bolts are provided at the four corners of the side of the fixed plate. Quick-release mechanisms for quickly disassembling the shearing blades are provided at both ends of the side of the fixed plate. A leveling mechanism for leveling the end face of the aluminum profile is provided at the bottom of the side of the fixed plate.

[0007] The quick-release mechanism includes first fixing blocks fixed to both ends of the side of the fixing plate. Each of the two first fixing blocks has a first sliding groove on its side. A second slider slides inside the first sliding groove. A first clamping plate is fixed to the other end of the second slider. A second clamping plate is located at the bottom of the first clamping plate. Anti-slip pads are provided on the sides of the first and second clamping plates that are close to each other, and a shearing blade is located between the two anti-slip pads. Second fixing blocks are fixed to the bottom of both ends of the side of the fixing plate. A second sliding groove is provided at one end of the side of the second fixing block, and an oblique sliding groove communicating with the second sliding groove is provided at the other end of the side of the second fixing block. A first slider slides inside the second sliding groove. A connecting block is fixed to the other end of the first slider. The tops of the two connecting blocks are respectively fixedly connected to the bottoms of the two second clamping plates. When the first slider moves into the oblique sliding groove, it will move the second clamping plate away from the bottom of the shearing blade, thus disassembling it.

[0008] Preferably, a collection tray is fixed to the bottom of both ends of the side of the fixing plate.

[0009] Preferably, the bottom of the first clamping plate has two symmetrical sliding holes, and a sliding rod is slidably provided inside the sliding hole, with the bottom of the two sliding rods fixed to the same second clamping plate.

[0010] Preferably, mounting plates are fixed to the top of both sides of the fixed plate, and a bidirectional lead screw is rotatably connected to the side of the two mounting plates that are close to each other. Symmetrical moving blocks are provided on the outer walls of both ends of the bidirectional lead screw, and connecting rods are fixed to the bottom of the two moving blocks. The bottom of the two connecting rods is fixedly connected to the top of the two first clamping plates respectively. A motor is installed at one end of one of the mounting plates, and the output shaft of the motor is fixedly connected to one end of the bidirectional lead screw.

[0011] Preferably, both ends of the bidirectional lead screw are provided with matching lead screw sleeves, and the outer walls of the two lead screw sleeves are respectively fixedly connected to the inner walls of the two moving blocks.

[0012] Preferably, L-shaped fixing plates are fixed to both ends of the side of the fixing plate, and an infrared sensor is installed on one side of the inner wall of the L-shaped fixing plate, with the infrared sensor located at one end of one of the shearing blades.

[0013] Preferably, the leveling mechanism includes an electric push rod installed at the bottom of one side of the fixed plate, and the output shaft of the electric push rod is fixedly connected to a leveling blade, which can level the end face.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the adoption of a quick-release mechanism, the infrared sensor is turned off, and then the motor is run to rotate the output shaft in the opposite direction. The bidirectional lead screw will drive the moving blocks to move away from each other, and also drive the two first clamping plates to move away. When the first slider moves into the inclined slide groove, the connecting block will pull the second clamping plate away from the first clamping plate, thereby achieving the effect of quick disassembly of the shearing blade. This reduces the time for manual disassembly and shortens the downtime of the equipment, thereby improving the overall utilization rate of the equipment. It is highly practical and easy to operate.

[0016] 2. Due to the adoption of a leveling mechanism, after the shearing is completed, the electric push rod is operated, which pushes the leveling blade to move and then level the end face of the aluminum profile. This process treats the end face of the sheared aluminum profile, resulting in a smoother cut and improving the production quality of the aluminum profile. Attached Figure Description

Detailed Implementation

[0024] The quick-release mechanism includes first fixing blocks 3 fixed to both ends of the side of the fixing plate 1. Each of the two first fixing blocks 3 has a first sliding groove 301 on its side. A second slider 309 slides inside the first sliding groove 301.

Anti-slip pads 306 are provided on the sides of the first clamping plate 305 and the second clamping plate 307 that are close to each other. A shearing blade 2 is provided between the two anti-slip pads 306. The first clamping plate 305 and the second clamping plate 307 can clamp and fix the top and bottom of the shearing blade 2. A second fixing block 302 is fixed at both ends of the side bottom of the blade 1. A second sliding groove 304 is opened at one end of the side of the second fixing block 302, and an inclined sliding groove 303 communicating with the second sliding groove 304 is opened at the other end of the side of the second fixing block 302. A first slider 3030 is slidably arranged inside the second sliding groove 304. A connecting block 3031 is fixed at the other end of the first slider 3030. The tops of the two connecting blocks 3031 are respectively fixedly connected to the bottoms of the two second clamping plates 307. When the first slider 3030 moves into the inclined sliding groove 303, it will drive the second clamping plate 307 away from the bottom of the shearing blade 2 and disassemble it.

[0025] In this utility model, a collection tray 7 is fixed at the bottom of both ends of the side of the fixing plate 1. The disassembled shearing blade 2 will fall into the collection tray 7 for collection.

[0026] In this utility model, the bottom of the first clamping plate 305 has two symmetrical sliding holes, and the sliding rods 308 are slidably provided inside the sliding holes. The bottom of the two sliding rods 308 is fixed with the same second clamping plate 307.

[0027] In this utility model, mounting plates 402 are fixed to the top of both sides of the fixed plate 1. A bidirectional lead screw 401 is rotatably connected to the side of the two mounting plates 402 that are close to each other. Symmetrical moving blocks 403 are provided on the outer walls of both ends of the bidirectional lead screw 401. A connecting rod 404 is fixed to the bottom of each of the two moving blocks 403. The bottom of the two connecting rods 404 is fixedly connected to the top of the two first clamping plates 305 respectively. A motor 4 is installed at one end of one of the mounting plates 402. The output shaft of the motor 4 is fixedly connected to one end of the bidirectional lead screw 401. The bidirectional lead screw 401 can drive the two shearing blades 2 to approach each other and cut the aluminum profile.

[0028] In this utility model, both ends of the bidirectional lead screw 401 are provided with matching lead screw sleeves, and the outer walls of the two lead screw sleeves are respectively fixedly connected to the inner walls of the two moving blocks 403.

[0029] In this utility model, L-shaped fixing plates 6 are fixed at both ends of the side of the fixing plate 1. An infrared sensor 601 is installed on one side of the inner wall of the L-shaped fixing plate 6, and the infrared sensor 601 is located at one end of one of the shearing blades 2. The infrared sensor 601 is electrically connected to an external controller. The controller can control the switch of the motor 4. When the shearing blade 2 blocks the signal of the infrared sensor 601, the motor 4 will stop running.

[0030] In this utility model, the leveling mechanism includes an electric push rod 5 installed at the bottom of one side of the fixed plate 1. The output shaft of the electric push rod 5 is fixedly connected to a leveling blade 501, which can level the end face.

[0031] Working Principle: In use, the fixing plate 1 is first fixed to the outlet of the extruder using fixing bolts 101. During fixing, the extrusion port 102 is aligned with the extruder's discharge port. When the aluminum profile needs to be cut, the motor 4 is operated, which drives the bidirectional lead screw 401 to rotate. The rotation of the bidirectional lead screw 401 causes the moving blocks 403 at both ends to move closer together. The moving blocks 403, through the connecting rod 404, drive the two first clamping plates 305 to move closer together. The first clamping plates 305 drive the second slider 309 to slide in the first slide groove 301, and also drive the second clamping plate 307 to move. Then, the two shearing blades 2 move closer to the aluminum profile and cut it. After cutting, the electric push rod 5 is operated, which pushes the flattening blade 501 to move and flatten the end face of the cut aluminum profile, making the cut smoother and improving production quality. During movement, when the shearing blade 2 moves below the infrared sensor 601, the infrared sensor 601 transmits data to the external sensor. When the signal is received, the controller will turn off the switch of motor 4. When it is necessary to disassemble and replace the shearing blade 2, the operation of infrared sensor 601 will be turned off, and then motor 4 will be started through the controller to move the two moving blocks 403 away from each other. Then the second clamping plate 307 will drive the connecting block 3031 to move, and drive the first slider 3030 to slide in the second slide groove 304. When the first slider 3030 moves into the inclined slide groove 303, the connecting block 3031 will pull the second clamping plate 307. The clamping plate 307 will drive the slide bar 308 away from the first clamping plate 305. At this time, the first clamping plate 305 and the second clamping plate 307 will release the shearing blade 2. The released shearing blade 2 will fall into the collection tray 7 for collection. Then, the new shearing blade 2 will be placed on top of the second clamping plate 307. Then, the motor 4 will be run and the bidirectional lead screw 401 will drive the two moving blocks 403 to move closer to each other. Then, the second clamping plate 307 will move closer to the first clamping plate 305 and clamp and fix the shearing blade 2.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
