Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum profile production equipment, in particular to an aluminum profile interruption shearing mechanism in the form of a crocodile shear. Background Art
[0002] Extruded aluminum profiles are a process in which aluminum alloy ingots are extruded through a die hole of a specific shape under high temperature and high pressure conditions by an aluminum profile extruder to form aluminum profiles with various cross-sectional shapes and sizes. After the aluminum profile is extruded from the extrusion equipment, it needs to be cut before entering the next equipment due to the continuity of extrusion. The current method is sawing, that is, the aluminum profile is cut by a saw blade. And in order to improve efficiency, the main method is to use follow-up sawing, so that sawing and extrusion are carried out simultaneously.
[0003] There are the following disadvantages when using saw blades to cut aluminum profiles:
[0004] 1. Aluminum shavings will be produced during the sawing process of aluminum profiles. The collection of aluminum shavings requires complex equipment and is a relatively troublesome process. Sawdust is also a loss of aluminum profiles.
[0005] 2. The noise generated during the sawing process is quite obvious in the entire aluminum extrusion workshop, and it is intermittent noise. This sharp and intermittent noise has a great impact on the comfort of production personnel;
[0006] 3. When sawing aluminum profiles, the saw blade needs to be spray lubricated. The loss of saw blades and lubricating oil is also a relatively important production expense. Summary of the invention

[0010] The follower frame carrying the shearing component moves synchronously with the extruded aluminum profile as a whole, and shears while extruding.
[0011] Preferably, a lifting source is provided under the follower frame, and the lifting source provides power to lift the follower frame and the shearing component above it as a whole in the vertical direction; when the follower frame descends, it is convenient for the extruded aluminum profile to follow through the shearing component, and when it rises, it lifts the bottom of the extruded aluminum profile to avoid large deformation of the extruded aluminum profile during the shearing process.
[0012] Preferably, the lifting source is a lifting cylinder, and the follower frame is driven to lift and lower in a vertical direction through a piston rod of the cylinder.
[0013] Preferably, two groups of lifting cylinders serving as lifting sources are provided and symmetrically arranged on both sides of the follower frame.
[0014] Preferably, the movable knife assembly comprises a movable knife seat and a movable blade, and the rear end of the movable knife seat is rotatably connected to the fixed knife assembly via a rotating shaft and bearing supports at both ends of the rotating shaft.
[0015] Preferably, the active source is a hydraulic cylinder, the piston rod of which is connected to an active arm and connected to a moving knife seat through the active arm. An active shear force is provided by the hydraulic cylinder and transmitted to the moving knife assembly through the active arm, so that the moving knife assembly rotates closer to the fixed knife assembly.
[0016] Preferably, the active source is a ball screw assembly, the screw nut is connected to the active arm, and is connected to the moving knife seat through the active arm. Driven by the motor, the screw nut provides an active shear force, which is transmitted to the moving knife assembly through the active arm, so that the moving knife assembly rotates close to the fixed knife assembly.

[0021] 1. The aluminum profile interruption shearing mechanism of the utility model in the form of crocodile shears cuts off the continuous extruded aluminum profiles by shearing. Compared with the traditional sawing, no aluminum chips are generated. At the same time, shearing greatly reduces the noise and improves the comfort of the workshop;
[0022] 2.
