The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The embodiment of this application is as follows:

[0019] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the automotive sealing strip straightening fixture of this utility model. Figure 2 This is a structural schematic diagram of the control component of this utility model. Figure 3 This is a structural schematic diagram of the guide component of this utility model.

[0020] This utility model discloses a tooling for straightening automotive sealing strips, comprising a base 101, a shaping mold 102, a fixing plate 103, a sliding rod 104, a movable plate 105, a pressure plate 106, a guide sleeve 107, a guide rod 108, a pressure sensor 109, a display 110, a screw 111, a knob 112, a locking nut 113, a limiting block 114, and a return spring 115. It solves the problem that existing technologies struggle to precisely control the pressure of the extrusion plate due to the varying straightening pressure required for sealing strips of different materials and thicknesses, leading to insufficient or excessive straightening and affecting product quality. It is understood that the aforementioned solution can also be used to improve the quality of straightening.

[0021] In this embodiment, the base 101 is used to provide stable support. The orthopedic component is installed on the base 101, thereby solving the problem that the orthopedic pressure required for sealing strips of different materials and thicknesses is different, and the existing technology is difficult to accurately control the pressure of the extrusion plate, which can easily lead to insufficient or excessive orthopedic correction and affect product quality.

[0022] The shaping mold 102 is detachably connected to the base 101 and located on one side of the base 101. The fixing plate 103 is fixedly connected to the base 101 and located on the side of the base 101 near the shaping mold 102. The sliding rod 104 passes through the fixing plate 103 and is slidably connected to the fixing plate 103. The movable plate 105 is fixedly connected to the sliding rod 104 and located at one end of the sliding rod 104 near the shaping mold 102. The pressure plate 106 is connected to the movable plate 105 through the guide member, which is mounted on the movable plate 105 and supports the pressure plate 106. The pressure sensor 109 is fixedly mounted on the movable plate 105 and located on the side of the movable plate 105 near the pressure plate 106. The display 110 is mounted on the base 101 and electrically connected to the pressure sensor 109. The control component controls the movement of the movable plate 105. Several threaded holes are provided at the top center of the base 101. The shaping mold 102 is bolted to the base 101. The shaping mold 102 can be replaced according to the model of the automotive sealing strip to adapt to different models of automotive sealing strips and improve adaptability. The number of fixed plates 103 is two symmetrically arranged. The molding mold 102 has two sets of sliding rods 104, each passing through one of the two fixed plates 103. Two movable plates 105 are connected to the ends of the two sets of sliding rods 104, allowing the movable plates 105 to slide on the fixed plates 103. Two pressure plates 106 are mounted on the two movable plates 105 via two sets of guide members, guiding the movement of the pressure plates 106. The two pressure plates 106 press the two sides of the automotive sealing strip against the molding mold 102, thereby pressing the automotive sealing strip... For the straightening process, two pressure sensors 109 are installed on the two movable plates 105 respectively to detect pressure. The display 110 is used to display the pressure data detected by the two pressure sensors 109. There are two sets of control components, which are used to control the movement of the two movable plates 105 respectively. By detecting the pressure of the pressure plate 106 through the pressure sensors 109, the pressure of the pressure plate 106 can be controlled more accurately. This solves the problem that the existing technology is difficult to accurately control the pressure of the extrusion plate due to the different straightening pressure required for sealing strips of different materials and thicknesses, which easily leads to insufficient or excessive straightening and affects product quality.

[0023] Secondly, the guide sleeve 107 passes through the movable plate 105 and is fixedly connected to the movable plate 105; the guide rod 108 is slidably connected to the guide sleeve 107 and fixedly connected to the pressure plate 106. The guide sleeve 107 is fixedly installed on the movable plate 105, and the guide rod 108 passes through the guide sleeve 107 and is slidably connected to the guide sleeve 107. Through the guide sleeve 107 and the guide rod 108, the movement of the pressure plate 106 is guided.

[0024] Meanwhile, the screw 111 passes through the fixed plate 103 and is threadedly connected to the fixed plate 103, and is rotatably connected to the movable plate 105; the knob 112 is fixedly connected to the screw 111 and is located at the end of the screw 111 away from the movable plate 105; the locking nut 113 is sleeved on the outside of the screw 111 and is threadedly connected to the screw 111; the fixed plate 103 has a threaded through hole, through which the screw 111 passes and is connected to the fixed plate 105. 3. Threaded connection: The end of the screw 111 is connected to the pressure plate 106 via a bearing. The knob 112 facilitates the rotation of the screw 111. The locking nut 113 is located between the knob 112 and the fixing plate 103. Tightening the locking nut 113 causes it to abut against the fixing plate 103, which locks and limits the screw 111, improving stability. By turning the knob 112, the movable plate 105 can be moved.

[0025] In addition, the limiting block 114 is fixedly connected to the guide rod 108 and is located at the end of the guide rod 108 away from the pressure plate 106. The limiting block 114 can limit the stroke of the guide rod 108 and prevent the guide rod 108 from slipping off the guide sleeve 107.

[0026] Finally, the reset spring 115 is sleeved on the outside of the guide rod 108 and located between the pressure plate 106 and the movable plate 105. The spring force of the reset spring 115 can assist the pressure plate 106 in resetting.

[0027] In this embodiment, during use, the deformed portion of the car sealing strip is placed on the shaping mold 102. Then, the two knobs 112 are tightened respectively, causing the two pressure plates 106 to move towards the shaping mold 102 until the two pressure plates 106 press the two sides of the car sealing strip firmly onto the shaping mold 102. Afterward, the pressure of the two pressure plates 106 is fed back to the display 110 through the two pressure sensors 109. The display 110 displays the real-time pressure of the two pressure plates 106. Then, according to the material and thickness of the car sealing strip, the pressure of the pressure plates 106 is adjusted to an appropriate value. The pressure value can be adjusted by turning the two knobs 112 again. Tightening increases the pressure, and loosening decreases the pressure. After the pressure is adjusted, the two locking nuts 113 are tightened respectively to maintain the stability of the two pressure plates 106. This application uses the pressure sensor 109 to detect the pressure of the pressure plate 106, thereby enabling more precise control of the pressure of the pressure plate 106. This solves the problem that the existing technology has difficulty in accurately controlling the pressure of the extrusion plate due to the different required straightening pressure for sealing strips of different materials and thicknesses, which can easily lead to insufficient or excessive straightening and affect product quality.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
