Description

Technical Field

[0001] The utility model relates to the technical field of shearing, in particular to a shearing device of an aluminum profile extruder. Background Art

[0002] The working principle of aluminum profile extrusion machine is based on the plastic deformation of metal. Under certain temperature and pressure conditions, aluminum undergoes plastic flow and continuously fills the mold cavity to obtain the desired product shape.

[0003] The cutting device currently used is that after the aluminum profile is extruded from the extruder, it is carried and guided by the conveyor rollers of the conveyor. At the same time, the cutting mechanism can be moved horizontally and its position is adjusted according to the cutting length requirements. After the rotating knife wheel moves up and down, the aluminum profile is cut.

[0004] However, for working conditions with a single production mode, such as cutting aluminum bars to a fixed length, the cutting device currently used is relatively complex and requires additional translation mechanisms, lifting mechanisms and other structures to be used in conjunction with the device. In addition, the device is large in size and has a high manufacturing cost. Therefore, in order to solve the above problems, a shearing device for an aluminum profile extruder is proposed.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a shearing device for an aluminum profile extruder, comprising a pair of linear guide rails 1, each of which is slidably mounted with a slide table, each of which is vertically arranged, each of which is fixedly mounted with a bearing seat 13, a same rotating shaft is rotatably mounted between the bearing seats 13, a synchronous wheel 14 is fixedly mounted at the center of the rotating shaft, one of the slides is fixedly mounted with a reduction motor 3 through a support seat, and the output end of the reduction motor 3 is connected to the rotating shaft; the upper side of the synchronous wheel 14 is used to support the aluminum rod, and the reduction motor 3 can drive the rotating shaft and the synchronous wheel 14 to rotate when working, and the slide can move up and down along the linear guide rail 1, thereby changing the support height of the aluminum rod to adapt to aluminum rods of different diameters, and has a wide range of applications.

[0026] A groove is provided on the circumferential side of the synchronous wheel 14, and a pair of pins 7 are fixedly installed inside the groove. A sleeve 8 is rotatably installed on the pin 7 through a torsion spring. One end of a swing arm 6 is fixedly installed on the sleeve 8, and a shear knife 5 is installed on the other end of the swing arm 6. The swing arm 6 can rotate on the pin 7 through the sleeve 8, and the torsion spring can make the swing arm 6 on the sleeve 8 have a force to move away from each other, so as to facilitate the opening and resetting of the swing arm 6.

[0027] The sides of the swing arms 6 that are away from each other are provided with slopes, and the upper sides of the linear guide rails 1 are rotatably installed with rollers 4 for pressing against the slopes; the various components in the grooves can rotate in a circle with the synchronous wheel 14, and when the sleeves 8 rotate up accordingly, the aluminum rod passes through between the two sleeves 8, and the slopes and the rollers 4 gradually press against each other, and the swing arms 6 can be swung closer to each other until the two shear knives 5 engage and shear the aluminum rod. When the swing arm 6 completely passes through the rollers 4, the swing arm 6 can be opened and reset, and the shearing action can be repeated in this way.

[0028] An electric cylinder 2 is fixedly mounted on one of the linear guide rails 1, and the push rod end of the electric cylinder 2 is fixedly assembled with the upper slide. The height of the synchronous wheel 14 can be changed by adjusting the extension and contraction amount of the electric cylinder 2, and the adjustment method is more convenient.

[0029] Specifically, a vibrator 11 is fixedly installed on one side of the linear guide 1 that is away from each other through a support seat, and a rotating drum 12 is rotatably installed on the circumferential side of the vibrator 11, and the rotating drum 12 is respectively against the roller 4; the vibration generated by the vibrator 11 when working will be transmitted to the roller 4 through the rotating drum 12, so that when the roller 4 is against the swing arm 6, it can be transmitted to the shearing knife 5, thereby further improving the shearing efficiency of the shearing knife 5.

[0030] A V-shaped annular groove 15 is provided on the circumferential side of the synchronous wheel 14. The aluminum rod produced by the extruder can be output along the V-shaped annular groove 15, thereby improving the walking accuracy of the aluminum rod on the synchronous wheel 14 and avoiding movement. In addition, the V-shaped annular groove 15 can hold aluminum rods of different diameters, which can play an auxiliary guiding role and has a wide range of applications.

[0031] See also Figure 2 , fan gears 9 are fixedly installed on the bottom of the circumferential side of the two barrel sleeves 8, and the two fan gears 9 are meshed and assembled with each other; the setting of the fan gears 9 can synchronize the rotation of the barrel sleeve 8, so that the opening and closing amplitudes of the swing arms 6 on both sides are always consistent, thereby improving the smoothness of the shearing action of the shearing knife 5.

[0032] The sector gear 9 is provided with a toothless area 10 at one end away from the shear knife 5. When the swing arms 6 on both sides are opened to the maximum position, the sector gear 9 will mesh with the toothless area 10 and cannot continue to mesh at this time, thereby limiting the opening angle of the swing arms 6.

[0033] The ends of the shearing knives 5 that are close to each other are chamfered, and the chamfers are arranged opposite to each other. This form of the shearing knives 5 is conducive to swinging and will not interfere with each other. When the shearing knives 5 are swung to be parallel to each other, the ends of the two shearing knives 5 that are close to each other overlap by at least 3 mm to ensure thorough shearing.

[0034] See also Figure 3 At least two screw holes are formed at the end of each swing arm 6 away from the sleeve 8, and the shearing knife 5 is provided with countersunk holes matching the screw holes, and bolts 16 are installed in the aligned countersunk holes and screw holes; the shearing knife 5 installed by the bolts 16 can be easily disassembled and replaced, reducing the maintenance downtime and maintaining the sharpness of the shearing knife 5.

[0035] Working principle:

[0036] The shearing device is installed between the conveying rollers of the conveyor. The aluminum rod produced by the extruder also passes through the top of the V-shaped ring groove 15 after being guided by the conveying rollers. At the same time, the reduction motor 3 drives the rotating shaft and the synchronous wheel 14 to rotate at a constant speed.

[0037] When the groove rotates one circle, the two swing arms 6 that are always open can swing closer to each other due to the gradual contact between the slope and the roller 4, until the two shear knives 5 are engaged and cut the aluminum rod. When the swing arm 6 completely passes through the roller 4, the swing arm 6 can be opened and reset, and the aluminum rod can be repeatedly cut to a fixed length in this way.

[0038] At the same time, the vibration generated by the vibrator 11 will be transmitted to the shearing knife 5 through the rotating drum 12, the roller 4, and the swing arm 6, thereby improving the shearing efficiency of the shearing knife 5.

[0039] In addition, when processing aluminum bars of different diameters, the height of the synchronous wheel 14 can be changed by adjusting the extension and contraction amount of the electric cylinder 2 to ensure the supporting effect.
