Description

Technical Field

[0001] This utility model relates to the field of deformation correction technology for mold steel, and more specifically, to a deformation correction device for mold steel. Background Technology

[0002] Die steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. Molds are the main processing tools for manufacturing parts in industries such as machinery manufacturing, radio instruments, motors, and electrical appliances. Die steel can be broadly classified into three categories: cold-rolled die steel, hot-rolled die steel, and plastic mold steel. They are used for forging, stamping, cutting, and die casting. When deformation occurs during the processing of die steel, deformation correction devices are required for correction.

[0003] Chinese patent application CN202322632249.1 discloses a mold steel deformation correction device, including a base, columns on both sides of the top of the base, a top plate on the top of the two sets of columns, a hydraulic cylinder in the middle of the top of the top plate, a correction block at the output end of the hydraulic cylinder, and a processing table in the middle of the top of the base. This utility model, through the cooperation between bevel gear A, motor, bevel gear B, rotating rod, pulley A, movable frame, push rod, hinge rod, pulley B, rotating tube, belt and clamping plate, enables the device to simultaneously move the two sets of clamping plates closer together to clamp and fix the mold steel by controlling the movable frame to move upward, which not only makes it convenient to fix the mold steel, but also improves the processing stability of the mold steel.

[0004] However, as can be seen from the accompanying drawings in the instruction manual, the deformation correction is achieved by clamping and fixing the mold steel with clamping plates. When the mold steel is a long strip structure, it is inconvenient to transport and move it during the correction process, which makes it difficult to load and unload the mold steel. Furthermore, it is inconvenient to adjust the correction position during stamping correction. Therefore, a deformation correction device for mold steel is proposed. Utility Model Content

By starting a motor to control the drive gear to drive the conveying pressure roller to rotate, the raw material can be moved towards the middle of the first support frame, which facilitates automatic loading and unloading and thus conveying long strip-shaped raw materials. Furthermore, by starting a stepper motor to control the limit slider to drive the hydraulic push rod and the stamping block to move, the position of the stamping block can be adjusted, thereby adjusting the correction position, which is convenient for adjustment and use.

[0017] 2. This utility model also controls the movement of the limiting clamp plate by activating the first electric push rod, which can limit the output raw material on both sides, improve the stability of raw material conveying, and push the limiting ring with the spring so that the buffer ring first fits the position of the deformed part of the raw material when the stamping block is stamped, which facilitates the buffering use of stamping correction. Furthermore, the stability of the buffer ring is improved by the cooperation of the limiting ring and the first stabilizing rod, and the stability of the movement of the limiting clamp plate is improved by the second stabilizing rod.
