Description

Technical Field

[0001] The utility model relates to the technical field of die steel processing equipment, in particular to a correction device for die steel. 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 mold directly affects the quality of the pressure processing process, the precision output of the product and the production cost. Die steel has the characteristics of high strength and wear resistance. In the production process, after casting, it needs to be forged at high temperature to increase the density of the die steel and make it shape. When die steel is forged at high temperature, it is generally forged into a rectangular ingot, steel plate or round steel, and then fine-processed according to subsequent use requirements. In the prior art, in order to improve the quality of the rectangular ingot or / and steel plate, it is necessary to repair the defects of the ingot or / and steel plate, and the straightening process is a relatively important part of the finishing process, which is mainly used to correct the shape defects of the ingot or / and steel plate. When the ingot or / and steel plate is corrected, it is generally stretched or pressure is applied to the surface of the ingot to achieve the purpose of straightening.

[0003] For example, the patent with publication number CN 219703051 U discloses a straightening device for mold steel materials, which includes a workbench, a base plate, an adjusting member, a positioning member and a straightening member. However, the straightening device still has certain shortcomings during use: for example, the positioning mechanisms on both sides of the base plate remain in a fixed position, so when the length of the steel is less than the distance between the positioning mechanisms on both sides, it is impossible to fix the two ends of the steel. At the same time, the position of the straightening member is fixed, so when the bending part of the steel does not correspond to the position of the straightening member, it is necessary to release the fixation of the steel and readjust the position of the steel, which is cumbersome.

[0004] To this end, the utility model provides a correction device for mold steel, which solves the above-mentioned problem by setting structures such as a correction mechanism and a fixing mechanism. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a correction device for mold steel, which solves the problem that the positions of the positioning mechanisms on both sides of the base plate in the existing straightening device remain fixed. Therefore, when the length of the steel is less than the distance between the positioning mechanisms on both sides, it is impossible to fix the two ends of the steel. At the same time, the position of the straightening component set therein remains fixed. Therefore, when the bending part of the steel does not correspond to the position of the straightening component, it is necessary to release the fixation of the steel and readjust the position of the steel, which causes cumbersome operation.

[0023] In this embodiment, the correction mechanism 3 is used to correct the mold steel, and the fixing mechanism 4 is used to fix the mold steel to ensure that the steel remains stable during the correction process.

[0024] Embodiment 2:

[0025] See also Figure 3-4 This embodiment provides a technical solution based on the first embodiment: the fixing mechanism 4 includes a base 41, and mounting plates 42 are symmetrically fixed on both sides of the base 41. The mounting plates 42 are fixed on the workbench 1 by bolts 43. A steel groove 44 is opened in the middle of the top wall of the base 41, and guide grooves 45 are symmetrically opened on both sides of the top wall of the base 41. An optical axis 46 is fixed in each of the guide grooves 45.

The knob 49 drives the threaded column 48 to rotate. During the rotation of the threaded column 48, the pressure plate 410 is driven to move downward until the pressure plate 410 is tightly pressed against the top wall of the steel. The telescopic rod 411 is used to prevent the pressure plate 410 from deflecting. The rubber pad can prevent the pressure plate 410 from damaging the surface of the steel and fix the steel more stably.
