Description

Technical Field

[0001] The utility model relates to a high-toughness cold-working die steel, in particular to a high-toughness cold-working die steel applied in the field of die steel plates. Background Art

[0002] Die steel is a type of steel used to make cold stamping dies, hot forging dies, die casting dies and other dies. Dies are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the die directly affects the quality of the pressure processing process, the precision output of the product and the production cost. The quality and service life of the die are mainly affected by the die material and heat treatment in addition to reasonable structural design and processing accuracy.

[0003] The specification of Chinese patent CN214570113U discloses a lifting device for moving mold steel, including a lifting rod, a circular hole is provided at the upper end of the lifting rod, and a hook is connected to the circular hole. When the utility model is in use, the two ends of the mold steel are respectively placed on the support plates of two sets of fixed frames, and the mold steel is clamped by sliding the mold steel clamping plate, so that mold steels of different lengths can be clamped.

[0004] The specification of Chinese patent CN208703540U discloses a new type of mold steel, including a mold steel body, which is in an inverted isosceles trapezoid. The utility model makes the mold steel into a trapezoid, and provides sockets for hanging steel wire ropes or hooks on both sides to facilitate hanging and lifting.

[0005] However, during the storage process, the above mold steels need to be stacked together. If they are placed for too long, there will be a risk of strong pressure wear, which is not conducive to ensuring the integrity and service life of the mold steel. Therefore, it is necessary to design a high-toughness cold-working mold steel with anti-compression function to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that if mold steels are stacked for too long, there will be a risk of strong pressure wear, which is not conducive to ensuring the integrity and service life of the mold steel.

[0007] In order to solve the above problems, the utility model provides a high-toughness cold working die steel, including multiple die steel plates, multiple magnetic surface layers are fixedly connected to the upper and lower ends of the die steel plates, a limiting ring is installed on the upper end of the magnetic surface layer, and a phase top angle column is installed on the inner end of the limiting ring. The phase top angle column includes a pair of deformable ring cylinders, and the inner end of the deformable ring cylinder is slidably connected with multiple flexible single rings. The inner end of the deformable ring cylinder is provided with an inner cavity groove, and the lower inner wall of the inner cavity groove is fixedly connected with multiple springs, and the end of the flexible single ring close to the magnetic surface layer is fixedly connected with an electromagnetic surface ring.

[0008] In the above-mentioned high-toughness cold-working die steel, this solution provides corner columns at the four corners of the die steel plate. When the die steel plates need to be stacked up and down after processing, the corner columns can be placed between adjacent die steel plates to avoid the risk of strong pressure wear caused by stacking the die steel plates for too long.

[0009] As a further improvement of the present application, a plurality of springs are connected to corresponding flexible single-loop rings, and the plurality of flexible single-loop rings are fitted with each other.

[0010] As a further improvement of the present application, the electromagnetic surface ring is magnetically connected to the magnetic surface layer, and multiple magnetic surface layers are respectively located at the four corners of the mold steel plate.

[0011] As a further improvement of the present application, an anti-collision ring layer is fixedly connected to one end of the flexible single-ring close to the mold steel plate, and the anti-collision ring layer is located on the inner side of the electromagnetic face ring.

[0012] As another improvement of the present application, a film cover layer is sandwiched between two adjacent mold steel plates, and the film cover layer is in contact with the outer wall surface of the mold steel plate.

[0013] As another improvement supplement of the present application, the area of ​​the film cover layer is larger than the area of ​​the mold steel plate, and the electromagnetic face ring is externally connected to a control terminal.

[0014] As another improvement of the present application, a plurality of writing whiteboards are fixedly connected to the outer end of the deformable ring tube, and information marks are provided on the outer ends of the writing whiteboards.

[0015] In summary, in this scheme, phase top corner columns are arranged at the four corners of the mold steel plate. When the mold steel plates need to be stacked up and down after processing, the phase top corner columns can be placed between adjacent mold steel plates to avoid the risk of strong pressure wear caused by stacking the mold steel plates for too long. When the phase top corner columns are in contact with the mold steel plates, an external control terminal can be used to make multiple electromagnetic face rings cycle from the outside to the inside to cut off power in sequence, effectively avoiding the risk of the phase top corner columns being in contact with the designated position outside the mold steel plate for a long time, causing the risk that the strength of its position is no longer consistent with that of the overall mold steel plate, which is beneficial to ensuring the uniformity of the practical strength of the mold steel plate.

[0025] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0026] The first implementation method:

[0027] Figure 2-6 It is shown that it includes multiple mold steel plates 1, and multiple magnetic surface layers 2 are fixedly connected to the upper and lower ends of the mold steel plates 1. A limiting ring 3 is installed on the upper end of the magnetic surface layer 2, and a phase top angle column 4 is installed on the inner end of the limiting ring 3. The phase top angle column 4 includes a pair of deformable ring tubes 5. The inner end of the deformable ring tube 5 is slidably connected with multiple flexible single rings 6. The inner end of the deformable ring tube 5 is opened with an inner cavity groove 8, and the lower inner wall of the inner cavity groove 8 is fixedly connected with multiple springs 9. The end of the flexible single ring 6 close to the magnetic surface layer 2 is fixedly connected with an electromagnetic surface ring 7.

[0028] Figure 2-6 It is shown that multiple springs 9 are connected to corresponding flexible single-loop rings 6, and multiple flexible single-loop rings 6 are fitted with each other, the electromagnetic surface ring 7 is magnetically connected to the magnetic surface layer 2, and multiple magnetic surface layers 2 are respectively located at the four corners of the mold steel plate 1, and the end of the flexible single-loop ring 6 close to the mold steel plate 1 is fixedly connected with an anti-collision ring layer 11, and the anti-collision ring layer 11 is located on the inner side of the electromagnetic surface ring 7, and a thin film cover layer 10 is sandwiched between two adjacent mold steel plates 1, and the thin film cover layer 10 is in contact with the outer wall surface of the mold steel plate 1, and the area of ​​the thin film cover layer 10 is larger than the area of ​​the mold steel plate 1, the electromagnetic surface ring 7 is externally connected to a control terminal, and the outer end of the deformable ring tube 5 is fixedly connected to multiple writing whiteboards 12, and the outer end of the writing whiteboard 12 is provided with an information mark.

[0029] Figure 1-6It is shown that in this scheme, phase top corner columns 4 are arranged at the four corners of the mold steel plate 1. When the mold steel plates 1 need to be stacked up and down after processing, the phase top corner columns 4 can be placed between adjacent mold steel plates 1 to avoid the risk of strong pressure wear caused by stacking the mold steel plates 1 for too long, and when the phase top corner columns 4 are in contact with the mold steel plate 1, an external control terminal can be used to make multiple electromagnetic surface rings 7 cycle from the outside to the inside and then retract away from the mold steel plate 1 by the spring 9. The interval time of the successive power-off can be set manually. The successive power-off forms multiple flexible single-loop rings 6 to generate magnetic force in turn, and then contact with the magnetic surface layer 2 on the wall of the mold steel plate 1, effectively avoiding the phase top corner columns 4 as a whole from being in contact with the designated position of the local outside of the mold steel plate 1 for a long time, causing the risk that the strength of its position is no longer unified with that of the overall mold steel plate 1, which is beneficial to ensuring the uniformity of the practical strength of the mold steel plate 1 and is not prone to defective positions.

[0030] The second implementation method:

[0031] Figure 2 , Figure 7 It is shown that a film cover layer 10 is arranged between the spaced mold steel plates 1. The area of ​​the film cover layer 10 is large enough to cover the mold steel plate 1 as a whole, so as to prevent dust and moisture from falling outside the mold steel plate 1 and affecting the quality of the finished product, which is beneficial to ensuring the service life of the mold steel plate 1. The model information of the mold steel plate 1 can be recorded on the writing whiteboard 12 outside the deformable ring tube 5, so that the writing whiteboard 12 faces outward for easy manual viewing, and there is no need to write directly on the mold steel plate 1.

[0032] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
