[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. The quality of the mold directly affects the quality of the pressure processing, the precision and output of the product, and the production cost. In addition to reasonable structural design and machining accuracy, the quality and service life of the mold are mainly affected by the mold material and heat treatment.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] Example

[0025] To address the problems of existing mold steel flatness testing equipment having a complex structure, being unable to accurately position the mold steel, and being unable to mark uneven areas during flatness testing, thus hindering subsequent repair of uneven areas, this paper refers to... Figure 1 and Figure 2 As shown, this application discloses a flatness testing device, including: a machine base 10, a support platform 20 and a clamping block 30 are arranged opposite each other on the upper part of the machine base 10, and a Y-axis driving component 40 connected to the clamping block 30 is arranged on the upper part of the machine base 10 for driving it to move closer to or away from the support platform 20.

[0026] XYZR axis drive mechanism 50, the XYZR axis drive mechanism 50 is mounted on the machine base 10, and the actuator of the XYZR axis drive mechanism 50 is equipped with a "[" shaped carrier seat 57.

[0027] The detection mechanism 60 includes a contact sensor 61. The main body of the contact sensor 61 is located above the lower plate of the "[" shaped carrier 57, and the detection head of the contact sensor 61 passes through the lower plate of the "[" shaped carrier 57.

[0028] The marking mechanism includes a flexible lifting marking component 70. A clearance groove 571 is provided on the lower plate of the "["-shaped carrier 57, and the flexible lifting marking component 70 is located on the vertical plate of the "["-shaped carrier 57 corresponding to the clearance groove 571.

[0029] In the specific implementation process, the mold steel to be tested is hoisted between the platform 20 and the clamping block 30 by a crane. The Y-axis drive component 40 is controlled to drive the clamping block 30 to extend and fix the mold steel. The XYZR axis drive mechanism 50 is controlled to drive the "[" shaped carrier 57 to the initial detection position and make the contact sensor in the direction of movement in front of the flexible lifting mark assembly 70. Under the drive of the XYZR axis drive mechanism 50, the contact sensor 61 will contact the surface of the mold steel. During the movement of the contact sensor 61, the contact sensor 61 will detect the flatness of the surface of the mold steel. If the contact sensor 61 finds an area of ​​abnormal flatness of the mold steel, the flexible lifting mark assembly 70 will immediately mark the position when it reaches the position.

[0030] As for the working principle of the contact sensor 61, the extension and retraction of the detection head of the contact sensor 61 when it contacts the standard flatness position is set to 2mm. During the flatness detection of the mold steel, if the extension and retraction of the detection head of the contact sensor 61 after contacting the mold steel is less than 1.5mm or greater than 2.5mm, it indicates that the flatness of that position is unqualified.

[0031] In order to achieve precise positioning of the mold steel, this application has a number of positioning holes 21 arranged in a straight line on the side of the platform 20 facing the clamping block 30, and positioning pins 80 that are inserted into two positioning holes 21. In actual use, the operator can insert the two positioning pins 80 into the corresponding positioning holes 21 according to the width of the mold steel. During placement, the mold steel should be pushed between the two positioning pins 80.

[0032] As a preferred embodiment, the Y-axis drive 40 of this application can be selected from hydraulic cylinders, pneumatic cylinders or electric cylinders. If other types of Y-axis drive 40 can also meet the functions of this application, those skilled in the art can choose them.

[0033] In this embodiment, the XYZR axis drive mechanism 50 of this application includes a Y-axis guide rail 52 and a Y-axis servo linear module 51 respectively disposed on the machine base 10 on both sides of the X-axis of the support platform 20 and the clamping block 30, a truss 53 connected to the Y-axis guide rail 52 and the Y-axis servo linear module 51, an X-axis servo linear module 54 disposed on one side of the crossbeam of the truss 53, a Z-axis pneumatic slide 55 connected to the X-axis servo linear module 54, an R-axis rotary cylinder 56 connected to the Z-axis pneumatic slide 55, and a "["-shaped carrier seat 57 connected to the output part of the R-axis rotary cylinder 56. With the cooperation of the Y-axis guide rail 52 and the Y-axis servo linear module 51, the truss 53 will realize the Y-axis movement, and the X-axis servo linear module 56 will realize the X-axis servo linear movement. Driven by the linear module 54, the Z-axis pneumatic slide 55 will move along the X-axis. Driven by the Z-axis pneumatic slide 55, the R-axis rotary cylinder 56 will move along the Z-axis. Driven by the R-axis rotary cylinder 56, the "["-shaped carrier 57 of this application can rotate. The R-axis rotary cylinder 56 drives the "["-shaped carrier 57 to rotate by 180° each time, which can switch the positions of the contact sensor 61 and the flexible lifting mark assembly 70, thereby ensuring that the contact sensor 61 is always in front of the flexible lifting mark assembly 70. In this way, the flexible lifting mark assembly 70 can mark the positions where the contact sensor 61 fails to detect.

[0034] In this embodiment, the flexible lifting marking assembly of this application includes a Z-axis linear cylinder 71, a mounting base 72, and a marking pen 73. A Z-axis guide rail 74 is provided on the vertical plate of the "["-shaped carrier 57, directly opposite the clearance groove 571. A sliding plate 75 is connected to the Z-axis guide rail 74. The Z-axis linear cylinder 71 is located on the horizontal plate of the "["-shaped carrier 57, and its piston rod is connected to the sliding plate 75. A connecting block 76 is provided on one side of the sliding plate 75. The piston rod of the Z-axis linear cylinder 71 moves through the connecting block 76. A limiting block 77 is provided at the end of the piston rod of the Z-axis linear cylinder 71. A spring 78 is fitted between the piston rod of 71 and the limiting protrusion and the connecting block 76. The mounting seat 72 is set on the sliding plate 75. The marking pen 73 passes through the inside of the mounting seat 72. When marking and scribing uneven positions, the Z-axis linear cylinder 71 drives the connecting block 76 to descend, and the sliding plate 75 and the marking pen 73 descend. When the marking pen 73 contacts the mold steel surface, it can elastically expand and contract, thereby avoiding the marking pen 73 from colliding with the mold steel and causing damage. During the process of the XYZR axis drive mechanism 50 driving the "[" shaped carrier seat 57 to move, the marking and scribing of unqualified positions is realized.
