[0002] The automobile roof is an important component of automobile interior, and its production process generally comprises two key procedures of raw material forming and cutting. In the prior art, the two procedures are generally completed by independent equipment, that is, the raw material is first processed into an automobile roof blank with a certain shape by a forming device, and then the blank is transferred to a cutting device for cutting to obtain an automobile roof product meeting the size requirements. However, this separate processing mode has many defects: firstly, two independent devices of the forming device and the cutting device need to be provided, which not only increases the device procurement cost, but also occupies a large production site; secondly, in the process of transferring the formed blank to the cutting device, the blank is easily damaged by external forces such as collision and extrusion, affecting the product quality; thirdly, the blank needs to be positioned twice in the two processing processes, the positioning error is large, the cutting precision is reduced, the size consistency of the automobile roof is difficult to guarantee, and then the assembly precision of the automobile roof and the vehicle body is affected; fourthly, the transfer between the procedures needs manual participation, which increases the labor cost and also reduces the production efficiency.

Further, the cutting area 9 is distributed in an inclined manner, and the upper surface of the cutting area 9 is smooth, so that the impurities falling during cutting can be collected in a concentrated manner. A lower die 4 is installed on the forming area 3, an installation frame 5 is connected to the rear end of the forming area 3, a hydraulic rod a 6 is installed at the upper end of the installation frame 5, and an upper die 7 is connected to the output end of the hydraulic rod a 6; a fixed plate 26 is installed on the cutting area 9, and a stop block 24 is installed at the upper end of the fixed plate 26; a guide block 13 is sleeved outside the guide rail 2, a fixed column 14 is installed above the guide block 13, a spring a 15 is connected inside the fixed column 14, a moving rod 16 is connected to the end of the spring a 15, a limiting frame 17 is installed at the upper end of the moving rod 16, and a convex plate 25 is installed at the four corners of the limiting frame 17. Further, the stop block 24 is located below the convex plate 25, and the stop block 24 and the convex plate 25 are distributed correspondingly, when the convex plate 25 moves to the position of the cutting area 9 following the limiting frame 17, the stop block 24 is used to block the convex plate 25, so as to avoid the downward movement of the limiting frame 17 under stress, so that the pressing plate 12 smoothly presses the sliding rod 22 to drive the cutting knife 23 to cut the preliminary blank. Further, the top end of the fixed column 14 is lower than the lowest point of the forming cavity of the lower die 4, the fixed column 14 is distributed at the four corners of the lower die 4, the position of the fixed column 14 is staggered with the position of the lower die 4, so that the limiting frame 17 has a long enough downward movement distance, and the upper die 7 and the lower die 4 are smoothly closed. A support frame 10 is installed at the rear end of the cutting area 9, a hydraulic rod b 11 is installed at the upper end of the support frame 10, and a pressing plate 12 is connected to the output end of the hydraulic rod b 11; a pressing assembly for limiting the forming raw material is arranged on the limiting frame 17, and a cutting assembly for cutting the edges of the formed preliminary blank is also arranged on the limiting frame 17. Further, the pressing assembly comprises a spring b 18 connected inside the limiting frame 17, a limiting rod 19 connected to the end of the spring b 18, and a roller 20 installed at the lower end of the limiting rod 19. Furthermore, the cutting assembly includes a slide bar 22 that passes through the limiting frame 17, a cutting blade 23 connected to the lower end of the slide bar 22, and a spring c21 connected between the cutting blade 23 and the limiting frame 17.

Specifically, when using this integrated car roof forming and cutting machine, the raw material is inserted into the limiting frame 17. At this time, the cutting blade 23 is stored in the limiting frame 17. When the raw material is inserted, due to the thickness of the raw material, the roller 20 will be driven by the raw material, causing the roller 20 to drive the limiting rod 19 to slide within the limiting frame 17. At the same time, the limiting rod 19 stretches and stores the spring b18.

At this time, the raw material is located between the upper mold 7 and the lower mold 4. The hydraulic rod a6 is opened, and under the control of the hydraulic rod a6, the upper mold 7 is moved downward. At this time, the upper mold 7 presses the raw material downward, and the limiting frame... 17 moves downward following the material under force. The limiting frame 17 drives the moving rod 16 installed at the lower end to move downward. The moving rod 16 stretches and stores the spring a15, so that the upper mold 7 and the lower mold 4 can be closed smoothly, pressing the material into the mold cavity. At the same time, the heating components in the upper mold 7 and the lower mold 4 start to work. Electric heating is used. The temperature sensor monitors the mold temperature in real time and transmits the temperature signal to the control system. The control system controls the heating power of the heating components according to the preset temperature parameters, heats the mold temperature to the preset temperature, and keeps the temperature stable. The hydraulic rod a6 applies a preset pressure to the upper mold 7, so that the material is heated and pressurized in the mold for a preset time, and is formed into a preliminary car roof blank. After the forming is completed, the hydraulic rod a6 is unloaded, the upper die 7 is driven to move upwards, the mold is opened, the movable rod 16 is driven to move upwards and reset by the force-storing spring a15, so as to drive the limiting frame 17 to move upwards and reset, push the limiting frame 17 to the right, at this time, the guide block 13 slides on the guide rail 2, moves the initially formed blank limited by the limiting frame 17 from the forming area 3 to the cutting area 9, when the guide block 13 at the right position moves to the baffle 8 at the right position, at this time, the position of the convex plate 25 corresponds to the position of the stop block 24, and the convex plate 25 is located above the stop block 24, limiting the limiting frame 17 from moving downwards under force, the hydraulic rod b11 is opened, the hydraulic rod b11 drives the pressing plate 12 to move downwards, the pressing plate 12 drives the sliding rod 22 to move, the sliding rod 22 drives the cutting knife 23 at the lower end to move downwards, at this time, the cutting knife 23 stretches and stores the spring c21, the cutting knife 23 is used to accurately cut the formed initially formed blank, and the automobile roof product is obtained, after the cutting is completed, the control hydraulic rod b11 drives the pressing plate 12 to move upwards, the force-storing spring c21 drives the cutting knife 23 to move upwards and reset, so that the cutting knife 23 is stored in the limiting frame 17, the automobile roof product is taken down, and the cutting waste is cleaned to the cutting area 9 and is concentrated to the right end position along the inclined surface of the cutting area 9, so that the concentrated cleaning is facilitated, the limiting frame 17 is pushed to the left, and is moved to the forming area 3, the above steps are repeated, and the continuous and integrated production of the automobile roof is realized, and the contents not described in detail in the description belong to the prior art known to those skilled in the art.
