Description

Technical Field

[0001] This utility model relates to the field of angle steel processing technology, and in particular to an angle steel cutting mold. Background Technology

[0002] Angle steel, also known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. Angle steel often needs to be cut and processed. Patent application number 202222926408.4 discloses an angle steel cutting die, including a lower die base, an upper die base above the lower die base, an upper pressure plate slidably disposed at the bottom of the upper die base, a lower pressure plate disposed at the top of the lower die base, a concave die fixing plate fixedly disposed at the bottom of the upper die base, a lower support spring fixedly disposed at the bottom of the lower pressure plate, the tail end of the lower support spring being fixedly connected to the top of the lower connecting frame, the lower part of the lower connecting frame being fixed to the top of the lower die base with screws, and the bottom sliding column of the lower pressure plate being slidably connected to the top sliding tube of the lower connecting frame. The upper pressure plate and the concave die fixing plate jointly press the lower and upper parts of the angle steel, reducing the deformation of the angle steel during cutting. However, the upper pressure plate generates downward pressure through the spring, and the spring is compressible. When the tail-lifting force generated during shearing is large, the upper pressure plate will move upward, causing the end of the angle steel away from the punch to lift up, and the cut surface will have a certain tilt during cutting.

[0015] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Detailed implementation method: combined with Figure 1-4As shown, an angle steel cutting die includes a lower die base 1 and an upper die base 6 slidably connected. A lower mounting base 2 is provided on the lower die base 1, and a lower blade 3 is provided on the inner side of the lower mounting base 2. A second channel 31 is provided on the lower blade 3, and a first channel 21 is provided on the lower mounting base 2. The first channel 21 and the second channel 31 have the same cross-section, and their bottom surfaces are both composed of two mutually perpendicular planes. The intersection of these two planes is located at the lowest point of the cross-section. A protruding plate 22 is provided on the outer side of the lower mounting base 2 above the first channel 21. A threaded hole penetrating its upper and lower surfaces is provided on the protruding plate 22, and a bolt 23 is connected to this threaded hole. The position of the bolt 23 can be adjusted vertically. An upper blade 4 is provided on the upper die base 6, and the lower part of the upper blade 4 is an isosceles right-angled triangle. In use, combined with… Figure 2 As shown, the angle steel is passed sequentially through the first channel 21 and the second channel 31, and the angle steel is kept horizontal. Then, the bolt 23 is rotated so that its lower end just presses against or almost presses against the angle steel (without significantly hindering the angle steel's movement along its length). When the upper blade 4 descends to cut the angle steel, the bolt 23 prevents this end from lifting, and the cut surface is not tilted during cutting. This mold can cut angle steel of various specifications, and in most cases, the angle steel does not contact the upper part of the first channel 21.

[0017] Furthermore, an upper mounting base 7 is provided on the upper mold base 6, and the upper blade 4 is fixed on the upper mounting base 7.

[0018] Furthermore, the upper mold base 6 is provided with a mold handle 5 for connecting to the device that drives the mold.

[0019] Furthermore, the lower mounting base 2 is provided with a stepped hole 24, and a clamping member 9 is slidably connected in the stepped hole 24. An upper spring 8 is provided above the clamping member 9, and a lower spring 10 is provided between the clamping member 9 and the bottom surface of the semi-through hole (i.e., the hole with a larger diameter) of the stepped hole 24. The stiffness coefficient of the upper spring 8 is much greater than that of the lower spring 10. A pressure column 91 is provided at the lower part of the clamping member 9. A pressure rod 61 is provided on the upper die base 6 and inserted into the stepped hole 24. When the upper die base 6 is fully raised, the pressure rod 61 moves slightly away from the top of the upper spring 8. At this time, the lower spring 10 pushes up the clamping member 9 so that the lower end of the pressure column 91 is just retracted into the stepped hole 24, without obstructing the angle steel from being inserted into the first channel 21. During cutting, the upper die base 6 descends, causing the pressure rod 61 to press the upper spring 8 downward, thereby pressing the pressure column 91 onto the angle steel, making it difficult for the angle steel to shift before the upper blade 4 contacts the angle steel.

[0020] Specifically, guide posts are provided on both sides of the lower mold base 1, and guide sleeves are provided on both sides of the upper mold base 6. The two guide posts are slidably connected to the two guide sleeves respectively.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
