Description

Technical Field

[0001] The utility model relates to the technical field of steel correction devices, in particular to a single-side flatness correction device for mold steel. Background Art

[0002] Mold steel is a type of steel used to manufacture cold stamping dies, hot forging dies, die-casting dies and other molds. It is a traditional mold material. Before correction, mold steel is not flat enough due to various factors, which affects the subsequent processing and use of the mold steel. Therefore, a correction device is needed to correct its flatness.

[0003] After searching, the related technology (CN220329634U) discloses a single-sided flatness correction device for mold steel, which aims to solve the technical problem of low correction efficiency of the current single-sided flatness correction device for mold steel. The device comprises a mounting frame, a horizontal moving mechanism is fixedly arranged at the top of the mounting frame, a fixing mechanism is fixedly arranged at the output end of the horizontal moving mechanism, a mounting seat A is fixedly arranged at the top of the mounting frame relative to the horizontal moving mechanism, an up and down adjustment mechanism is fixedly arranged at the top of the mounting seat A, a correction structure is fixedly arranged at the output end of the up and down adjustment mechanism, the correction structure comprises a mounting seat B, both ends of the mounting seat B are parallel and equidistantly connected to a plurality of rollers, a polishing mechanism is fixedly arranged in the middle of the mounting seat B. The utility model has the advantages of clear and compact structural design and high correction efficiency.

[0004] However, the above technical solution still has some shortcomings. For some relatively thin mold steels, once they become uneven, it is still difficult to restore them to flatness even after correction due to toughness problems. In order to ensure the correction effect, the correction is generally repeated more than twice. This means that after one correction, the mold steel needs to be transported from the correction outlet to the correction entrance for correction again, which is relatively laborious and inconvenient. Therefore, it is necessary to propose a single-sided flatness correction device for mold steel. Utility Model Content

[0023] A support shaft 4 is rotatably installed on the stand 1, and the top end of the support shaft 4 is fixedly connected to the bottom of the frame 5.

A supporting frame 3 is fixedly installed on the bottom of the stand 1, and the bottom end of the support shaft 4 is rotatably connected to the supporting frame 3.

[0024] Through the above technical solution, the direction of the correction mechanism can be automatically reversed, so that after the mold steel is initially corrected and discharged, it can be corrected again without being transported, eliminating the tediousness of transporting the mold steel.

[0025] Two first hydraulic rods 6 are fixedly installed on the top of the frame 5, and a first support frame is installed for lifting inside the frame 5. The output rods of the two first hydraulic rods 6 are fixedly connected to the top of the first support frame, and the shafts at both ends of the two upper deforming wheels 7 are rotatably connected to the first support frame. The second motor is fixedly connected to the first support frame, and the output shaft of the second motor is fixedly connected to the shaft of one of the upper deforming wheels 7. The first synchronous wheels are fixedly connected to the shafts at the other ends of the two upper deforming wheels 7, and the two first synchronous wheels are sleeved with first synchronous belts.

[0026] Through the above technical solution, the upper deforming wheel 7 can be adjusted in height so that it can better adapt to mold steels of different thicknesses, and the linear distance between the upper deforming wheel 7 and the lower deforming wheel 8 needs to be smaller than the thickness of the mold steel, so that the mold steel can be deformed and reshaped during the transportation process.

[0027] The shafts at both ends of the two lower deforming wheels 8 pass through the frame 5 and are rotatably connected to the frame 5. The third motor is fixedly connected to one side of the frame 5. The output shaft of the third motor is fixedly connected to the shaft of one of the lower deforming wheels 8. The second synchronous wheels are fixedly connected to the shafts at the other ends of the two lower deforming wheels 8. The two second synchronous wheels are provided with second synchronous belts.

[0028] Through the above technical solution, the two lower deforming wheels 8 can rotate synchronously, so as to cooperate with the upper deforming wheel 7 to transport the mold steel, and complete the reshaping of the mold steel while transporting it.

[0029] Two second hydraulic rods 9 are fixedly installed on the top of the frame 5, and a second support frame is lifted and lowered inside the frame 5. The output rods of the two second hydraulic rods 9 are fixedly connected to the top of the second support frame, and the shafts at both ends of the multiple upper correction wheels 10 are rotatably connected to the second support frame. The fourth motor is fixedly connected to the second support frame, and the output shaft of the fourth motor is fixedly connected to the shaft of the corresponding upper correction wheel 10.

[0032] Through the above technical solution, multiple lower correction wheels 11 can rotate synchronously, so that the multiple lower correction wheels 11 can drive the mold steel to be transported, thereby completing the correction of the mold steel.

[0033] A bidirectional screw 13 is rotatably mounted on the platform 1, and a sixth motor 12 for driving the bidirectional screw 13 is fixedly mounted on the platform 1.

Two driving frames 14 are threadedly sleeved on the bidirectional screw 13, and the two driving frames 14 are respectively fixedly connected to the bottom of two crawler conveyors 15.

[0034] Through the above technical solution, the two crawler conveyors 15 can be driven to move closer to or farther from each other, so that when the correction mechanism is turned around, the two crawler conveyors 15 will not cause any restriction.

[0035] The implementation principle of a single-sided flatness correction device for mold steel in the embodiment of the present application is:

[0036] The first step: when the mold steel is corrected for flatness, the mold steel is placed on the crawler conveyor 15 at the entrance of the correction mechanism, and then the second motor, the third motor, the fourth motor and the fifth motor are started to operate the upper deformation wheel 7, the lower deformation wheel 8, the upper correction wheel 10 and the lower correction wheel 11. Subsequently, the crawler conveyor 15 at the entrance conveys the mold steel into the frame 5. When the mold steel passes through the upper deformation wheel 7 and the lower deformation wheel 8, it will be restricted to become a wave shape, thereby completing the reshaping of the mold steel, so that it will not be backtracked due to toughness during subsequent correction and leveling. Subsequently, when the mold steel enters the upper correction wheel 10 and the lower correction wheel 11, it will become a flat plate, thereby completing the plane correction of the mold steel and making it flatter;

[0037] The second step: when the mold steel after preliminary correction falls on the crawler conveyor 15 at the exit, start the sixth motor 12, which drives the two driving frames 14 and the two crawler conveyors 15 to move away from each other through the bidirectional screw 13, so as to provide space for the rotation of the frame 5. Then, start the first motor 2, which drives the support shaft 4 and the frame 5 to rotate through the two first bevel gears, so that the frame 5 rotates 180 degrees and changes direction, and transfers the upper deformation wheel 7 and the lower deformation wheel 8 to the mold steel, and then resets the two crawler conveyors 15. At this time, the mold plate does not need to be moved and the mold plate can be corrected again.

[0038] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
