[0002] A guardrail is a component used for edge protection, safety isolation or traffic guidance. It is usually made of metal, plastic or other durable materials. Its design and material selection usually depend on the specific purpose and environment to ensure that it can provide effective safety and isolation functions under various conditions. Among them, the more common is the wavy guardrail. When the wavy guardrail is made by stamping, the plate needs to be placed on a wavy mold. Through the stamping of a hydraulic press, the upper and lower molds squeeze the plate into a wavy shape. However, there is a certain height difference between the two sides and the middle part of the wavy mold. When the plate is placed on the mold, it is easy for the plate to tilt and shift, resulting in unqualified products. After the stamping is completed, it is inconvenient to remove the guardrail because the guardrail fits the mold. Utility Model Content

The movable block 25 slides up and down on the inner side of the connecting groove 22. When the movable block 25 slides to the bottom of the connecting groove 22, the top height of the movable block 25 is flush with the bottom height of the protrusion 21. A spring 252 is provided at the bottom of the movable block 25. The movable block 25 can be moved upward and reset through the connection of the spring 252, so that the top of the movable block 25 is flush with the top of the protrusion 21, and the top of the movable block 25 is in a concave state. The concave surface of the top of the movable block 25 is an arc surface matching the top size of the protrusion 21. A supporting side plate 11 is provided on one side of the support base 1. The supporting side plate 11 is fixedly connected to the support base 1, and the supporting side plate 11 is vertically aligned with the support base 1. The fixed plate 2 is straight, one side of the fixed plate 2 is connected to one side of the supporting side plate 11, and a connecting top plate 111 is provided on the top of one side of the supporting side plate 11, and the connecting top plate 111 is fixedly connected to the supporting side plate 11, and the connecting top plate 111 is perpendicular to the supporting side plate 11, and a plurality of hydraulic cylinders 3 are located at the bottom of the connecting top plate 111, and a movable plate 4 is provided at the bottom of the hydraulic cylinder 3, and the movable plate 4 is parallel to the fixed plate 2, and the movable plate 4 has the same size as the fixed plate 2, and the height of the movable plate 4 can be increased or decreased by telescoping the hydraulic cylinder 3, and a groove 41 is provided at the bottom of the movable plate 4, and the groove 41 is located in the middle of the movable plate 4, and the concave surface of the groove 41 is also an arc surface, and two protrusions 42 are provided at the bottom of the movable plate 4, and the two protrusions 42 are located on both sides of the groove 41 , and the two protrusions 2 42 are symmetrical to each other, the length of the protrusion 2 42 is the same as the length of the movable plate 4, the groove 41 corresponds to the position of the protrusion 1 21, and the protrusion 2 42 corresponds to the position of the movable block 25. When the height of the movable plate 4 decreases, the protrusion 1 21 will enter the inner side of the groove 41, and at the same time, the protrusion 2 42 will enter the inner side of the movable block 25. By placing the plate between the fixed plate 2 and the movable plate 4, the plate can be stamped into a wavy guardrail plate by reducing the distance between the movable plate 4 and the fixed plate 2. When the stamping is completed, the movable block 25 is moved upward and reset by the spring 252, and the guardrail plate will move upward with the upward movement of the movable block 25, so that the guardrail plate is separated from the protrusion 1 21, which is convenient for demoulding the guardrail plate.When the plate is located on the top of the protrusion 21 and the movable block 25, since the top of the movable block 25 is flush with the protrusion 21, it is easy to position the plate, so that the plate remains horizontal, avoiding the plate being easily offset due to the height difference of the corrugated mold.

[0019] A clearance groove 23 is provided at the bottom of the connecting groove 22, and the two ends of the spring 252 are fixedly connected to the bottom of the movable block 25 and the bottom of the clearance groove 23 respectively; when the movable block 25 moves down to the bottom and touches the bottom of the connecting groove 22, the spring 252 will shrink on the inner side of the clearance groove 23. Since the position of the clearance groove 23 is lower than the connecting groove 22, the spring 252 will not interfere with the downward movement distance of the movable block 25.

[0020] A guide rod 251 is provided at the bottom of the movable block 25 , and the guide rod 251 is located inside the spring 252 ; the guide rod 251 is perpendicular to the bottom of the movable block 25 , and the movable block 25 can be guided by the guide rod 251 .

[0021] A slide groove 24 is provided at the bottom of the clearance groove 23, and a guide rod 251 is slidably connected to the inner side of the slide groove 24; the connection between the guide rod 251 and the slide groove 24 can prevent the movable block 25 from being displaced in the horizontal direction during the up and down movement.

[0022] The second protrusion 42 has the same size as the first protrusion 21, and the shape of the groove 41 matches that of the first protrusion 21, and the second protrusion 42 matches the top shape of the movable block 25; when the movable plate 4 moves downward to squeeze the plate, the proximity of the second protrusion 42 and the movable block 25 will cause the plate to sink downward, and the proximity of the protrusion 21 and the groove 41 will cause the plate to bulge upward.

[0023] The working principle and use process of the utility model are as follows: when in use, since the spring 252 has a certain supporting force on the movable block 25, the movable block 25 will maintain a position where the top is flush with the top of the protrusion 21, and then, the plate is placed on the top of the protrusion 21 and the two movable blocks 25 to keep the plate in a horizontal state, and then, the movable plate 4 is moved downward by the hydraulic cylinder 3. When the movable plate 4 moves downward to squeeze the plate, the proximity of the protrusion 242 and the movable block 25 will cause the plate to sink downward. At the same time, the height of the movable block 25 will drop until the top of the movable block 25 is flush with the bottom of the protrusion 21, and the proximity of the protrusion 21 and the groove 41 will cause the plate to bulge upward, thereby stamping the plate into a wavy shape. When the movable plate 4 moves upward and resets, the spring 252 can make the movable block 25 move upward and reset, and the guardrail plate will move upward with the upward movement of the movable block 25, so that the guardrail plate is separated from the protrusion 21, which is convenient for demoulding the guardrail plate.
