Description

Technical Field

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

[0002] The extrusion residue is the residual material produced after extruding aluminum profiles. After the aluminum profile extruder extrude the profile, the extrusion residue needs to be sheared by a shearing device. The current shearing is mainly carried out by pushing the shearing knife close to the extrusion die entrance of the extruder through the shear rod to shear the residual material of the aluminum profile material rod after extrusion.

[0003] In the prior art, in order to ensure the flatness of the cut surface of the shearing knife when shearing the profile, a lining pressure plate is usually set on the upper cover of the scissor seat to press the shearing knife and the scissor seat, and the lining pressure plate is adjusted with a fixing screw to make the shearing knife and the scissor seat fit more closely. However, since the shearing knife moves up and down in the scissor seat, this pressing method usually aggravates the wear between the shearing knife and the scissor seat and the lining pressure plate and generates a gap again, resulting in a rapid decrease in shearing accuracy and a significant reduction in the service life of the shearing device.

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0031] like Figure 1-6 The example shown is an embodiment provided by the utility model.

[0032] The utility model embodiment provides a residual shearing device for an aluminum profile extruder, comprising: a scissors seat 10, a shearing telescopic cylinder 20 and a shearing knife 30, the scissors seat 10 is groove-shaped and arranged in the vertical direction, the shearing telescopic cylinder 20 is arranged at the upper end of the scissors seat 10, the shearing knife 30 is slidably arranged in the scissors seat 10, the outer side wall of the scissors seat 10 is detachably provided with a cover plate 12 for preventing the shearing knife 30 from falling out, the lower end, i.e., the telescopic end, of the shearing telescopic cylinder 20 is connected to the shearing knife 30, and can drive the shearing knife 30 to slide up and down along the scissors seat 10; a clamping mechanism 11 is arranged on the outer side wall of the scissors seat 10 near the lower end, the clamping mechanism 11 comprises a first telescopic oil cylinder 111 and a pressing plate 112, the first telescopic oil cylinder 111 is arranged on the outer side wall of the scissors seat 10 and is perpendicular to the outer side wall of the scissors seat 10, the pressing plate 112 is located on the inner side wall of the scissors seat 10, and the movable end of the clamping mechanism 11, i.e., the telescopic end of the first telescopic oil cylinder 111 passes through the scissors seat 10 The outer wall is connected to the pressure plate 112, so that the pressure plate 112 can move back and forth toward the inside of the scissors seat 10 as the first telescopic oil cylinder 111 is extended and retracted, and cooperates with the shearing knife 30 sliding up and down in the scissors seat 10. When the shearing knife 30 slides downward to the lower end of the scissors seat 10 and corresponds to the position of the pressure plate 112, the telescopic end of the first telescopic oil cylinder 111 extends to move the pressure plate 112 toward the shearing knife 30, and presses the shearing knife 30 against the bottom wall of the scissors seat 10, so that the shearing knife 30 continues to move downward and the cutting pressure is more neat. When the shearing knife 30 slides upward after cutting, the telescopic end of the first telescopic oil cylinder 111 drives the pressure plate 112 to retract, so that the fit between the shearing knife 30 and the scissors seat 10 is relatively loose. The whole process can greatly reduce the friction distance and friction time between the shearing knife 30 and the scissors seat 10, thereby reducing the wear of the shearing knife 30 and the scissors seat 10, and extending the service life of the shearing knife 30 and the scissors seat 10. In addition, the pressing mechanism 11 can flexibly adjust the pressing force on the shearing blade 30 , and can be adjusted according to the degree of wear of the shearing blade 30 , thereby further extending the service life of the shearing blade 30 .

The inner side wall of the blade body 32 abuts against the bottom wall of the scissors seat 10. The inner side wall of the blade 31 is parallel to the bottom wall of the scissors seat 10 and spaced from each other, so that the blade 31 does not directly rub against the bottom wall of the scissors seat 10. The blade 31 can move up and down relatively stably and reduce wear, which can further extend the service life of the blade 31. Specifically, an extrusion die opening 41 is provided directly below the scissors seat 10. Driven by the shear telescopic cylinder 20, the shearing knife 30 will move downward along the scissors seat 10 and gradually extend out of the lower end of the scissors seat 10, and then cut the pressure residue of the extrusion die opening 41. The inner side wall of the blade 31 is flush with the extrusion die opening 41, and the pressure residue generated at the extrusion die opening 41 can be neatly cut off.

In addition, a reinforcing fixing block 45 is provided on the top of the die base 40, and the reinforcing fixing block 45 is fixedly connected to the scissor seat 10, so that the scissor seat 10 is firmly fixed on the die base 40.

[0035] Furthermore, a discharge guide groove 42 is provided on the front side wall of the mold base 40, and the discharge guide groove 42 is slidably arranged along the horizontal direction of the mold base 40.

[0036] Furthermore, a limit block 43 and a second telescopic cylinder 44 are provided on the front side wall of the mold base 40. The limit block 43 is located directly above the extrusion mold opening 41. The limit block 43 is connected to the lower end of the second telescopic cylinder 44 and moves up and down with the lower end of the second telescopic cylinder 44. The limit block 43 can prevent the material from being lifted up or offset after discharging, thereby ensuring that the direction of discharging extends vertically forward.
