Profile shears with insertable blades

Description

[0001] Profile shears, in particular for cutting round bars, polygonal bars or the like, are known in which loose blades are inserted from the side. from which they can be inserted into their seats. In these previously known scissors, a guide channel is recessed in the scissor body or in the blade carriage. which terminates at one of the narrow ends of the scissor body. This known arrangement and design is flawed insofar as Valuable space is lost due to the canal's narrow-sided mouth. This is because the canal's mouth is located at one end, forcing... In profile shears with punch and notcher, these two tools are used together on one side, namely on the side of the opening of the insertion channel. to arrange them on the opposite side. However, this is undesirable for reasons of easy accessibility and handling of the die and Uncoupling as well as increased wear on the punch guide when the clinker is on the punch.

[0002] The invention aims to avoid these shortcomings of previously known profile shears with insertable blades. It achieves According to the invention, this objective is achieved essentially by providing the guide channel for the insert knives with a transversely directed channel, from which The insertion opening is assigned to the broad side of the scissors. This ingenious measure ensures that the blades are inserted from the broad side. The scissors can be inserted into the slot, meaning both narrow end faces of the scissors are available for other tools. This enables the punch and notcher to be positioned on two opposite sides of the machine, similar to scissors without an insert blade. to attach the scissor body.

[0003] To facilitate the insertion of the knives, the outer edge of the insertion opening can be chamfered or rounded, so that the The knife can be inserted at a slight angle.

[0004] The invention is illustrated in an exemplary embodiment in the drawing. Fig. i shows a partial section of a Cutting profiles of various types using specific profile shears and Fig. 2 shows a cut made here along line II-II of Fig. i.

[0005] In the drawing, the scissor body formed from a strong plate is designated by 3, which has guides q on its front side. the knife carriage 5. The guide ¢ for the carriage 5, which carries the movable knife plate 6, is extended forward by a cover 7. closed. Both the lid and the scissor body have three cutouts (8) that serve to allow the material to be cut to pass through. while the two knife blades, namely the fixed knife io engaging in a seat 9 of the scissor body 3 and the one in a seat ii of the The carriage has 5 horizontal movable knives 6 with recesses r2 corresponding to the profiles to be cut.

[0006] The blades 6, 10 lie loosely in the scissor body 3 and slide 5. To insert the blades, a [missing word] is provided in the scissor body 3 and in the slide 5. The width of the knives 6, 10, includes a corresponding guide channel 13 through which the knives are inserted one after the other from the side, i.e., obliquely from above. can be inserted.

[0007] In contrast to previously known scissors of this type, in which the guide channel 13 running laterally into the scissor mouth is for the blades as the channel 13 extends to the narrow end face of the scissors, the channel in the invention is only extended by an amount corresponding to the length of the blade. guided outside the lid 7 and open at this point towards the broad side of the scissors. The insertion opening 1q is accordingly perpendicular to the direction of Channel 13.

[0008] The knives are inserted individually one after the other through the insertion opening i4 in the direction of arrow A (Fig. 2) and then slide into Direction of the arrow. B into their seats. To facilitate the insertion of the knives into opening 1q. or to make this opening as small as possible. To ensure that the outer edge 15 of the insertion opening is chamfered or otherwise broken over at least part of its depth, the knives are held in can be inserted in a slightly inclined position.

[0009] As already mentioned, the embodiment shown is only an example implementation of the invention and the invention is not limited to, Rather, many other designs and applications are possible. For example, the profile shear does not necessarily require a punch. and a notcher is provided. The new design and arrangement of the insert could of course also be advantageously applied to differently designed ones. and use equipped scissors with insertable blades.
