Description

Technical Field

[0001] This utility model relates to the field of mold steel technology, and more specifically, to a bending-resistant mold steel. Background Technology

[0002] Die steel is a type of steel used to manufacture dies such as cold stamping dies, hot forging dies, and die-casting dies. Dies are the main processing tools in industries such as machinery manufacturing, radio instruments, motors, and electrical appliances, used for manufacturing parts. The quality of the dies directly affects the quality of pressure processing, product precision and output, and production costs. The quality and service life of dies, besides relying on reasonable structural design and processing precision, are mainly influenced by the die material and heat treatment. Die steel can be broadly classified into three categories: cold-rolled die steel, hot-rolled die steel, and plastic die steel, used for forging, stamping, cutting, and die casting. Due to the different uses and complex working conditions of various dies, die steel, depending on the working conditions of the dies it manufactures, should possess high hardness, strength, wear resistance, sufficient toughness, and high hardenability, quenchability, and other processing properties. Because of these different uses and complex working conditions, the performance requirements for die steel also vary.

[0003] Existing mold steel structures, especially plate mold steel structures, need to withstand large forces during actual use. If the thickness is too thin, deformation and bending are likely to occur. For equipment used in precision machining, deformation and bending will lead to product defects and affect production schedule. Therefore, it is necessary to design a structure that can increase the bending resistance of mold steel to solve this problem. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a bending-resistant die steel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending-resistant mold steel, comprising a mold steel body, wherein first steel plates are fixedly connected to the upper and lower outer walls of the mold steel body, and the outer walls of the two first steel plates are provided with first arc-shaped protrusions, and second steel plates are fixedly connected to the two ends of the two first steel plates at the upper and lower surfaces of the mold steel body, and the outer walls of each second steel plate are provided with second arc-shaped protrusions, and clamping plates are connected between the upper and lower second steel plates on the same side at the two ends of the mold steel body.

[0006] As a further improvement to the technical solution of this utility model, the height of the first arc-shaped protrusion is equal to the height of the second arc-shaped protrusion, and the thickness of the first steel plate and the second steel plate are equal.

[0007] As a further improvement to the technical solution of this utility model, both ends of the first steel plate are connected to the outer wall of the mold steel body with first locking bolts. The outer wall of the first steel plate is provided with a first groove at the end position of the first locking bolt, and the inside of the first steel plate is provided with a first internal thread hole that matches the thread at the position of the screw of the first locking bolt.

[0008] As a further improvement to the technical solution of this utility model, the first internal threaded hole is connected to the bottom of the first groove, and the top end of the first locking bolt does not exceed the horizontal position of the outer surface of the first steel plate.

[0009] As a further improvement to the technical solution of this utility model, the card plate has a U-shaped structure, and both ends of the card plate are provided with T-shaped card blocks that are slidably engaged with the outer walls of the upper and lower second steel plates. The outer walls of the second steel plates are provided with T-shaped grooves in the horizontal direction corresponding to the outer side of the T-shaped card blocks.

[0010] As a further improvement to the technical solution of this utility model, the upper and lower ends and the outer side wall of the card plate are connected to the mold steel body by a number of second locking bolts. The outer wall of the card plate is provided with a second groove corresponding to the end of each second locking bolt, and the inside of the card plate is provided with a second internal thread hole corresponding to the screw of each second locking bolt.

[0011] As a further improvement to the technical solution of this utility model, the second internal threaded hole is connected to the interior of the second groove, and the end head of each second locking bolt does not extend beyond the outer surface of the corresponding position on the card plate.

[0012] The beneficial effects of this utility model are:

[0013] This invention adds an anti-bending structure to the main body of the mold steel. The anti-bending structure facilitates assembly and disassembly. After assembly, the clamping plate itself is stabilized by the compression and locking of the second locking bolts at multiple positions and by the limiting effect of the T-shaped clamping block. The first and second steel plates are fixed together by welding and are limited to horizontal sliding by the T-shaped clamping block. When the second locking bolts are tightened, the screw head of the first locking bolt at the rear end is used to compress and increase friction, thereby maintaining stability in the horizontal direction. The ends of the first and second locking bolts will not exceed the outer surface of the installed first steel plate and clamping plate, and will not protrude to the outside to affect the subsequent stacking of multiple mold steels. Furthermore, the first and second arc-shaped protrusions on the first and second steel plates are designed to prevent bending from the protruding position, thereby increasing the overall bending resistance of the mold steel.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-4 The bending-resistant mold steel shown includes a mold steel body 1. The upper and lower outer walls of the mold steel body 1 are fixedly connected with first steel plates 2. The outer walls of the two first steel plates 2 are provided with first arc-shaped protrusions 3. The two ends of the two first steel plates 2 are welded and fixed to the upper and lower surfaces of the mold steel body 1. The outer wall of each second steel plate 4 is provided with a second arc-shaped protrusion 5. The upper and lower second steel plates 4 on the same side are connected with clamping plates 6 at the two ends of the mold steel body 1.

[0021] As attached Figure 1-3 As shown, the height of the first arc-shaped protrusion 3 is equal to the height of the second arc-shaped protrusion 5, and the thickness of the first steel plate 2 and the second steel plate 4 is equal, which makes it easy for the mold steel as a whole to remain stable during subsequent stacking and prevents tilting.

[0022] As attached Figure 1 and attached Figure 3As shown, both ends of the first steel plate 2 are connected to the outer wall of the mold steel body 1 by first locking bolts 9. The outer wall of the first steel plate 2 is provided with a first groove 10 corresponding to the end position of the first locking bolt 9. The inside of the first steel plate 2 is provided with a first internal thread hole 11 corresponding to the external position of the screw of the first locking bolt 9. The first internal thread hole 11 is connected to the bottom of the first groove 10. The top end of the first locking bolt 9 does not exceed the horizontal position of the outer surface of the first steel plate 2, which facilitates the connection and disassembly between the second steel plate 2 and the mold steel body 1.

[0023] As attached Figure 1-4 As shown, the card plate 6 has a U-shaped structure, and both ends of the card plate 6 are provided with T-shaped card blocks 7 that slide and engage with the outer walls of the upper and lower second steel plates 4. The outer walls of the second steel plates 4 are provided with T-shaped grooves 8 in the horizontal direction corresponding to the outside of the T-shaped card blocks 7, which facilitates the connection between the card plate 6 and the two second steel plates 4.

[0024] As attached Figure 1 and attached Figure 4 As shown, the upper and lower ends and the outer side wall of the clamping plate 6 are connected to the mold steel body 1 by a number of second locking bolts 12. The outer side wall of the clamping plate 6 is provided with a second groove 13 corresponding to the end of each second locking bolt 12. The inside of the clamping plate 6 is provided with a second internal thread hole 14 corresponding to the screw of each second locking bolt 12. The second internal thread hole 14 communicates with the inside of the second groove 13. The end of each second locking bolt 12 does not extend beyond the outer surface of the corresponding position of the clamping plate 6, which facilitates the locking and fixing of the clamping plate 6.

[0025] Working principle: This utility model designs a bending-resistant die steel, the specific structure of which is shown in the attached instruction manual. Figure 1-4As shown, in this technical solution, an anti-bending structure is added to the mold steel body 1. During assembly, two clamping plates 6 are first placed at both ends of the mold steel body 1, and then the second locking bolts 12 are tightened to fix it by the compression of the bolt heads. At this time, the first steel plate 2, which is welded with the second steel plate 4, is placed on one side of the end of the mold steel body 1, so that the T-shaped clamping block 7 at the end of the clamping plate 6 slides into the T-shaped groove 8 on the second steel plate 4, and then slides to the middle position of the mold steel body 1. The first locking bolt 9 is then tightened. At this time, the clamping plate 6 itself is clamped and locked by the compression of the second locking bolts 12 at multiple positions, and the T-shaped clamping block 7 is kept stable by the limiting, while the first steel plate 2 and the second steel plate 4 are fixed by welding. The mechanism is integrated, and due to the horizontal limitation of the T-shaped locking block 7, it can only slide horizontally. When the second locking bolt 9 is tightened, the screw head at the rear end of the first locking bolt 9 is screwed in to compress and increase friction, thereby maintaining stability in the horizontal direction. The ends of the first locking bolt 9 and the second locking bolt 12 will not exceed the outer surface of the installed first steel plate 2 and the locking plate 6, and will not protrude to the outside to affect the subsequent stacking of multiple mold steels. Furthermore, the first arc-shaped protrusion 3 and the second arc-shaped protrusion 5 set on the first steel plate 2 and the second steel plate 4 are not prone to bending from the protruding position of the arc, thereby increasing the overall bending resistance of the mold steel.

[0026] In the accompanying drawings of the embodiments disclosed in this utility model, only the structures involved in the embodiments of this utility model are shown. Other structures can be referred to with ordinary design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

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.
