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 1-6 The automobile shock absorber upper plate stretching forming equipment shown includes a conveying mechanism 1, a frame 2, a movable mold 3, a fixed mold 4 and a pick-and-place mechanism 5, forming an automated assembly line. There are two pick-and-place mechanisms 5, one of which takes the raw material from the conveying mechanism 1 and puts it between the movable mold 3 and the fixed mold 4. After the movable mold 3 and the fixed mold 4 are extruded and formed, the molded part is taken out from the fixed mold 4 by another pick-and-place mechanism 5 and put on the conveying mechanism 1 again. It can be seen that the conveying mechanism 1 needs to be divided into two parts, namely the original conveyor belt 101 and the finished product conveyor belt 102, and the fixed mold 4 is located between the original conveyor belt 101 and the finished product conveyor belt 102, that is, the original conveyor belt 101 and the finished product conveyor belt 102 are respectively located in the opposite directions of the fixed mold 4.

[0028] Each pick-and-place mechanism 5 is movably connected to the frame 2, and the frame 2 includes a pair of side frames 220, and the two side frames 220 are centrally symmetrical. Specifically, each side frame 220 includes a longitudinal side panel 221, and the lower end of each side panel 221 has a transverse bottom panel 222, and the bottom panel 222 is fixedly arranged. A baffle 224 is fixedly connected to one side of the side panel 221, and another baffle 224 is fixedly connected to the other side through an extension plate 223, that is, the distances between the two baffles 224 and the commonly connected side frames 220 are different, and a guide rail 225 is fixedly connected between the two baffles 224, and the guide rail 225 is in the horizontal direction, so the extension directions of the two sets of guide rails 225 are opposite, and usually, the extension direction of the guide rail 225 is parallel to the movement direction of the original conveyor belt 101 and the finished product conveyor belt 102.

[0029] The specific structure of the pick-and-place mechanism 5 includes a telescope 502. Since the movement accuracy requirement of the telescope 502 is not high, a cylinder can be used. The end of the telescope 502 away from the shaft frame 503 is fixedly connected with a slider 501, which is used to cooperate with the guide rail 225 to form a sliding pair. The outer surface of the guide rail 225 is provided with a straight tooth groove. The slider 501 has a servo motor and a reducer inside. The input end of the reducer is fixedly connected to the output end of the servo motor through a coupling. The output end of the reducer is fixedly connected with a gear, which is suitable for meshing with the straight tooth groove on the guide rail 225, thereby ensuring that the slider 501 has high movement accuracy.

[0030] The movable end of the telescope 502 faces the fixed mold 4 and is fixedly connected to the shaft frame 503, to which a rotary drive 504 is fixedly connected and a clamping claw 505 is movably connected. The clamping claw 505 is driven by the rotary drive 504. In order to achieve the clamping action, the clamping claw 505 is divided into two upper and lower parts, both of which are rotatably connected to the shaft frame 503. Therefore, the upper and lower parts of the clamping claw 505 can move relative to each other to achieve clamping and releasing actions. Each shaft frame 503 has two rotary drives 504, which respectively drive the two parts of the clamping claw 505 to swing relative to the shaft frame 503. The two parts of the clamping claw 505 can move independently, and have high clamping flexibility.

[0031] The frame 2 also includes a cross frame 210, which includes a beam plate 211 fixedly connected to the upper ends of two side plates 221. The beam plate 211 is in the horizontal direction, and the center of the beam plate 211 is fixedly connected to a hydraulic cylinder 6 through a mounting sleeve 212. The hydraulic pressure can be used to generate a large extrusion force to cause the raw material to produce tensile deformation. The movable end of the hydraulic cylinder 6 is downward and fixedly connected to the movable mold 3. The movable mold 3 realizes lifting and closing and splitting actions driven by the hydraulic cylinder 6. The fixed mold 4 is located directly below the movable mold 3. When under pressure, the force will be in the vertical direction, which is more stable. The bottom surface of the fixed mold 4 is fixedly connected to a workbench 7, and the workbench 7 is also fixedly set. The end surface of the fixed mold 4 with a mold cavity is also provided with a first makeshift groove 401 and a second makeshift groove 402, which are respectively opposite to the two pick-up and placement mechanisms 5, and are used to fit with the extended structure of the edge of the part to facilitate the pick-up and placement mechanism 5 to grab the part.

[0032] Working principle: The pick-and-place mechanism 5 on the extension plate 223 close to the original conveyor belt 101 is responsible for placing the raw material on the original conveyor belt 101 on the fixed mold 4. The movable mold 3 moves downward under the drive of the hydraulic cylinder 6 to squeeze the raw material into the mold cavity of the fixed mold 4. The extension structure at the edge of the raw material sinks into the first make-way groove 401 and the second make-way groove 402. The movable mold 3 moves upward under the drive of the hydraulic cylinder 6 and separates from the fixed mold 4. The raw material becomes a molded part. The two clamping claws 505 clamp the extension structure at the opposite side edges of the molded part at the same time to lift the molded part out of the mold cavity of the fixed mold 4. Then, the clamping claw 505 on the extension plate 223 close to the original conveyor belt 101 releases the extension structure on the molded part protruding from the first give way groove 401, and the clamping claw 505 on the extension plate 223 close to the finished product conveyor belt 102 remains in a clamped state and is slightly lifted up under the drive of the rotary drive 504, so that the molded part can completely fall off the mold cavity of the fixed mold 4, and finally, the molded part is placed on the finished product conveyor belt 102 under the drive of the slider 501, completing a round of automatic stretching and forming work, and then entering the next round and repeating the above work process.

[0033] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
