DETAILED DESCRIPTION

[0023] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0026] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0027] like Figure 1-7The die steel billet turning and limiting platform shown in the figure comprises a pair of parallel clamps 2, and the two clamps 2 are mirror images of each other, and are arranged up and down in the horizontal state, and each clamp 2 has a pair of parallel roller frames 201 on the opposite surfaces, and the roller frames 201 and the clamps 2 are an integral structure, but are obviously protruding from the surface of the clamps 2, and a hydraulic cylinder 3 is connected between the two clamps 2 to provide a large traction force, and the two ends of the hydraulic cylinder 3 are connected to the part of the clamp 2 outside the two roller frames 201, that is to say, the setting position of the roller frame 201 is not close to the edge, but the two ends of the roller frame 201 may be flush with the side of the clamp 2, and the hydraulic cylinder 3 is connected to the clamp 2. The pressure cylinder 3 includes a cylinder barrel 301 and a telescopic rod 302 that cooperate with each other, which are two main parts for realizing telescopic movement. The end of the cylinder barrel 301 facing away from the telescopic rod 302 is fixedly connected to the surface of one splint 2, and the end of the telescopic rod 302 facing away from the cylinder barrel 301 is fixedly connected to the surface of another splint 2. Usually, the thinner telescopic rod 301 will be located above the thicker cylinder barrel 302, so the end of the telescopic rod 301 will be fixedly connected to the lower surface of the upper splint 2, and the end of the cylinder barrel 302 will be fixedly connected to the upper surface of the lower splint 2. The fixed connection method can ensure that the upper and lower splints 2 can maintain a symmetrical state.

[0028] A plurality of limiting rollers 1 are arranged between the two roller frames 201 on the same clamping plate 2, which are used to directly contact the die steel billet. The axes of the plurality of limiting rollers 1 are in the same plane and are parallel, and can contact the die steel billet at the same time, which is conducive to dispersing the force and reducing the pressure. The main part of the limiting roller 1 is the roller shaft 101, and the two ends of the roller shaft 101 have coaxial end shafts 102. The diameter of the end shaft 102 is significantly smaller than the roller shaft 101, so as to form a stepped structure for inhibiting the movement of the roller shaft 101 after plugging. The two roller frames 201 on the same clamping plate 2 are provided with corresponding shaft holes 202 for contacting with the end shafts. 102, specifically: the upper group of limiting rollers 1 cannot rotate relative to the upper clamping plate 2, so the upper several limiting rollers 1 are interference fit with the upper pair of roller frames 201; and the lower group of limiting rollers 1 must be able to rotate relative to the lower clamping plate 2, so the lower several limiting rollers 1 are rotationally matched with the lower pair of roller frames 201, and the limiting rollers 1 on the same clamping plate 2 are equidistantly arranged, which is conducive to uniform contact between the roller shaft 101 and the mold steel billet. The outer side surface of the roller shaft 101 is wrapped with a rubber layer, which can effectively avoid scratches caused by direct hard contact between the roller shaft 101 and the processed surface of the mold steel billet.

[0029] A frame 4 is arranged below the clamping plate 2 for suspending the main body of the device at a certain height from the ground. The frame 4 includes a bottom plate 401 directly in contact with the placement surface. The bottom plate 401 is usually provided with a connecting hole structure for bolts and other connecting parts to pass through for fixation. A pair of brackets 402 are fixedly connected to the upper surface of the bottom plate 401. The two brackets 402 are symmetrical front to back. The two clamping plates 2 are just arranged between the two brackets 402. A driver 5 is arranged on the frame 4 for adjusting the angle of the main body of the device. The driver 5 is fixedly connected to the opposite side of the bracket 402, that is, the side facing away from the clamping plate 2. The driver 5 includes a motor 501 and a reducer 502. The housings of the motor 501 and the reducer 502 are connected to the brackets. The bracket 402 is fixedly connected to ensure the stability of their positions. The reducer 502 is driven by the motor 501. The reducer 502 can reduce the output speed of the motor 501 and increase the output torque to make the output more stable. The upper surface of the upper clamping plate 2 is provided with an extension plate 203. In this embodiment, the extension plate 203 is obviously protruding from the upper surface of the upper clamping plate 2. Of course, the extension plate 203 can also be located on the lower surface of the upper clamping plate 2. Both settings can achieve the same function. The end face of the extension plate 203 facing the bracket 402 is provided with a drive shaft 204. The drive shaft 204 passes through the bracket 402 and is linked with the output shaft of the reducer 502, thereby driving the clamping plate 2 to adjust the angle and realize the flipping of the mold steel square billet.

[0030] Working principle: After the processing of one narrow side of the die steel billet is completed, the side will remain facing upward and be transported to the upper push platform next to the turning limit platform through the conveying equipment. In the initial state of the limit platform, the clamping plate 2 is in a horizontal state, the driver 5 is not subjected to force, the upper and lower clamping plates 2 are far away from each other, and the distance between the two clamping plates 2 is greater than the thickness of the billet. When the billet approaches, the driver 5 will start to tilt the end of the clamping plate 2 close to the billet downward, and then the upper push platform will push the billet between the upper and lower clamping plates 2, and then the hydraulic cylinder 3 will contract to make the upper clamping plate 2 close to the lower clamping plate 2 Since the upper limiting roller 1 cannot rotate and the roller shaft 101 is wrapped with a rubber material with greater friction, the billet will not slide out from between the two clamping plates 2 after the upper pusher table moves downward. Then the driver 5 is started again, driving the clamping plate 2 to deflect to the other side, and the originally lower side will gradually become the higher side. Finally, the hydraulic cylinder 3 extends, and the upper clamping plate 2 is released from the clamping state. The billet will roll relative to the lower clamping plate 2 until it slides out from between the two clamping plates 2. In this way, the unprocessed side of the billet originally at the bottom will be turned upward and enter the next processing station for further processing.
