[0001] The invention relates to the technical field of automobile covering part molds, and in particular to a hidden self-balancing reverse turning device for automobile covering part molds. Background Art

[0002] Automobile covering parts refer to the spatially shaped surface or internal parts made of metal sheets that cover the engine, chassis, cab, and body. According to the function and location, they can be divided into three categories: external covering parts, internal covering parts, and skeleton covering parts. They have different characteristics from general stamping parts in terms of process design, mold processing, equipment selection, and quality control. The manufacturing of new energy vehicles is developing rapidly. With the improvement of technology, in order to save energy and reduce consumption and improve the utilization rate of raw materials, automobile covering parts are constantly combined and lightweight to reduce manufacturing costs and manufacturing processes, while promoting the high performance, high strength, and lightweight energy saving of automobiles, which greatly increases the difficulty of manufacturing automobile covering parts molds.

[0016] 2. In the present invention, after the negative angles of deformation existing on the two side flanges of the automobile battery guard plate are processed, the two rotating plates can be controlled to rotate and reset from the inside of the automobile battery guard plate.

If the two movable plates are not smooth during the movement, or cannot move further after moving to a certain position, there is still deformation in this position that cannot be completely processed, and the second shaping plate can continue to be controlled to continue shaping this position.

[0018] 4. In the present invention, when the fixed mold needs to be inspected and maintained after being used for a period of time, the two processing tables can be controlled to move towards each other, and with the help of the telescopic ends of the two groups of hydraulic cylinders below, they can be extended upward together to drive the two processing tables to move upward until the tops of the two processing tables abut against the two upper pressure blocks at the bottom of the movable mold. At this time, the two processing tables cooperate with the two groups of hydraulic cylinders arranged at the bottom to support and limit the movable mold, thereby preventing the staff from accidentally touching the switch during the inspection of the fixed mold, causing the movable mold to move downward, causing injuries to the staff, and further improving the safety of the staff in inspecting the fixed mold.

Rotating seats 8 are rotatably installed on both sides of the base 1, and auxiliary shaping mechanisms for shaping the edge flanging parts of the automobile cover after stamping are arranged above the two rotating seats 8. Processing tables 5 for cooperating with the auxiliary shaping mechanisms are symmetrically arranged on the top of the base 1. The tops of the two processing tables 5 are each provided with a first driving mechanism for assisting the metal plate to be stamped and formed to be transported to the top of the fixed mold 3, and the insides of the two processing tables 5 are each provided with a second driving mechanism for driving the automobile cover after stamping to rotate and adjust the position. During actual use, two first drive motors are preset inside the base 1, and the output ends of the two first drive motors are respectively connected to the rotating parts of the two rotating seats 8, so that the two rotating seats 8 can be driven to rotate downward, so that they can drive the entire auxiliary shaping mechanism downward to be hidden under the base 1, and then control it to rotate upward to the working position during subsequent use.

[0024] As a technical optimization solution of the present invention, the auxiliary shaping mechanism includes a first slide groove 15 opened inside the two rotating seats 8, and the first sliders 16 are installed inside the two first slide grooves 15. A group of first electric telescopic rods 12 are installed on the top of the two first sliders 16, and the telescopic ends of the two groups of first electric telescopic rods 12 are installed with rectangular plates 9. First linear motors are preset inside the two first slide grooves 15, and the two first linear motors respectively drive the two first sliders 16 to move back and forth inside the corresponding first slide grooves 15, so that the positions of the first electric telescopic rods 12, the rectangular plates 9 and other components can be adjusted together.

[0025] As a technical optimization scheme of the present invention, the outer wall of the side close to the two rectangular plates 9 is provided with a first groove, the inside of the two first grooves is installed with a double-headed screw 17, the outer wall of the two double-headed screws 17 is symmetrically installed with two mounting blocks 18, the two ends of the fixed mold 3 are provided with a first shaping plate 6, the outer wall of the two mounting blocks 18 away from the double-headed screw 17 is connected with a clamping block 14 through the second electric telescopic rod 13, and the two corresponding clamping blocks 14 are respectively tightly abutted against the outer walls of the two sides of the first shaping plate 6 close to it. In actual use, a second driving device is preset on the outer wall of one side of the two rectangular plates 9, and the output ends of the two second driving devices are respectively connected to one end of the two double-headed screws 17, so that the two double-headed screws 17 can be driven to rotate and adjust in the corresponding first groove; so that the two mounting blocks 18, the two second electric telescopic rods 13 and the clamping block 14 can move towards or away from each other as the double-headed screw 17 rotates.

[0026] As a technical optimization solution of the present invention, the outer walls on the side away from the two first shaping plates 6 are each provided with a plurality of sliding grooves 23, and sliding plates 22 are slidably installed inside the plurality of sliding grooves 23. Second grooves are each provided at the bottom of the plurality of sliding plates 22, and sliding blocks 21 are slidably installed inside the plurality of second grooves. The plurality of sliding blocks 21 and their corresponding second grooves are connected by springs 20.

[0027] As a technical optimization solution of the present invention, a mounting plate 19 is commonly installed at the bottom ends of multiple sliding blocks 21, a second shaping plate 4 is installed on the outer wall of the mounting plate 19 away from the first shaping plate 6, and the end of the mounting plate 19 close to the first shaping plate 6 is provided with an inclined surface that abuts against each other. In the process of the top end of the first shaping plate 6 being forced to move downward, the multiple sliding plates 22 are driven to move downward together. Since the bottom end of the second shaping plate 4 will contact the formed automobile cover during use, the first shaping plate 6 moves downward, driving the inclined surface to abut against the inclined surface of the mounting plate 19. Since the bottom ends of the multiple sliding plates 22 are limited by the second shaping plate 4 to move downward, they can only slide upward inside the corresponding sliding groove 23, and will not interfere with the downward movement of the first shaping plate 6. With the elastic extension of the multiple springs 20, the second shaping plate 4 is driven to move in the direction away from the first shaping plate 6, so that the vertical downward force can be converted into a horizontal force, and the negative angle generated at the flanged part of the automobile cover is trimmed, so that it does not need to be processed by other equipment later, thereby improving the efficiency of stamping and forming of automobile covers.

[0028] As a technical optimization solution of the present invention, two first rotating blocks are rotatably installed at both ends of the movable mold 2, and an upper pressing block 10 is installed between the two matching first rotating blocks. When in use, the two upper pressing blocks 10 can be rotated by means of a third driving device preset inside the movable mold 2, driving the two corresponding first rotating blocks and the upper pressing blocks 10 to rotate downward to the bottom of the movable mold 2, so that when the movable mold 2 moves downward, it drives the two upper pressing blocks 10 to move downward together to press the top of the first shaping plate 6.

[0029] As a technical optimization solution of the present invention, the first driving mechanism includes two groups of second slide grooves 7 opened on the top of the base 1, and the second sliders 35 are installed inside the two groups of second slide grooves 7. The tops of the two groups of second sliders 35 are installed with hydraulic cylinders 11, and the telescopic ends of the two groups of hydraulic cylinders 11 are installed with connecting seats, and the two groups of connecting seats are respectively installed at the bottom of the processing table 5 close thereto. Second linear motors are preset inside the two groups of second slide grooves 7, and the two groups of second linear motors can respectively drive the two groups of second sliders 35 to move back and forth inside the corresponding second slide grooves 7, and drive the hydraulic cylinders 11 and the connecting seats set on the top thereof to move back and forth.

[0030] As a technical optimization solution of the present invention, two rectangular sleeves 24 are installed at the bottom of the ends of the two processing tables 5 that are close to each other, wherein the inside of the two rectangular sleeves 24 are installed with limit blocks 25, and two sets of electric push rods 26 are installed at the bottom of one of the processing tables 5, and the telescopic ends of the two sets of electric push rods 26 are connected to the limit blocks 25 that are close to it. After the two processing tables 5 move toward the direction of approaching and docking, the telescopic ends of the two sets of electric push rods 26 can be controlled to extend, pushing one end of the two limit blocks 25 to move to the inside of the other two rectangular sleeves 24, thereby providing support for the connection between the two processing tables 5, and facilitating the use of the two processing tables 5.

[0031] As a technical optimization scheme of the present invention, third slide grooves 30 are provided on the outer walls on both sides of the two processing tables 5, third sliders are installed inside the two third slide grooves 30, connecting blocks 27 are installed on the ends of the two third sliders away from the third slide grooves 30, and a rotating plate 32 is rotatably installed between the two connecting blocks 27. Rectangular grooves are provided inside the two rotating plates 32, and two cleaning pads 33 are symmetrically installed inside the two rectangular grooves. Fourth slide grooves 34 are provided on the tops of the two rotating plates 32, and two movable plates 28 are slidably installed inside the two fourth slide grooves 34. A third linear motor is preset inside the two third slide grooves 30, and the two third linear motors can drive the two third sliders to move back and forth inside the corresponding third slide grooves 30, thereby driving the two connecting blocks 27 to move back and forth; a second servo motor is preset inside one of the connecting blocks 27, and the output end of the second servo motor is connected to the rotating part of one end of the rotating plate 32, thereby driving the rotating plate 32 to rotate and adjust; and a double-headed screw is preset inside the fourth slide groove 34, and both ends of the double-headed screw pass through one end of the two moving plates 28 inside the fourth slide groove 34, and one end of the double-headed screw is connected to the preset output end of the driving device, thereby driving the two moving plates 28 to move towards or away from each other.

[0032] As a technical optimization solution of the present invention, the second driving mechanism includes two arc grooves 29 opened inside the two processing tables 5, and electric sliders 31 are installed inside the two arc grooves 29, and electromagnets are installed at the tops of the two electric sliders 31. The two electric sliders 31 can move inside the corresponding arc grooves 29 when in use. After the electromagnets at the tops of the two electric sliders 31 are magnetically attracted to the stamped automobile cover, the two electric sliders 31 are controlled to move in the same clockwise or counterclockwise direction, and the magnetically attracted automobile cover is driven to rotate and adjust.

[0033] In the present invention, when the user uses the device, Figure 1As shown, the telescopic ends of one of the hydraulic cylinders 11 located at the front can be controlled to retract downward, driving the processing table 5 above it to move downward to a state flush with the top of the fixed mold 3, and the telescopic ends of another group of hydraulic cylinders 11 located at the back can be controlled to retract downward, driving the processing table 5 above it to move downward to a state where the top is higher than the top of the fixed mold 3. When the metal sheet to be stamped is pushed to the top of the fixed mold 3 by the external preset pushing device, the processing table 5 located in front of the fixed mold 3 can be used as an auxiliary loading platform, and the metal sheet can pass through the rectangular groove inside one of the rotating plates 32. The two cleaning pads 33 arranged inside can automatically clean the upper and lower sides of the metal sheet respectively. After the metal sheet falls on the top of the movable mold 2, the processing table 5 located on the back can limit the continued forward movement of the metal sheet, and control the extension of the telescopic ends of the two sets of second electric telescopic rods 13, pushing the first shaping plate 6 clamped and fixed by the two clamping blocks 14 to move in a direction close to each other, so that at this time the two first shaping plates 6 can limit and fix the other two sides of the metal sheet, and the metal sheet can accurately fall on the top of the fixed mold 3, and move downward with the help of the movable mold 2 above, so that it can be stamped into a car battery guard plate part.

[0034] After the movable die 2 and the fixed die 3 cooperate to punch the metal sheet into the automobile battery guard plate, if the automobile battery guard plate is stuck inside the fixed die 3, causing the preset ejection mechanism inside the fixed die 3 to be unable to automatically eject it upward, the two processing tables 5 at this time can be controlled to move to a state flush with the fixed die 3, and then the two rotating plates 32 themselves can be controlled to rotate 90 degrees between the corresponding two connecting blocks 27, driving the two rotating plates 32 to rotate to a horizontal state, and the two movable plates 28 on the top of the two rotating plates 32 are rotated to the side close to the fixed die 3, and then the two rotating plates 32 are controlled to move in a direction close to each other. Until the two horizontal rotating plates 32 drive the two movable plates 28 to be inserted into the gap between the automobile battery guard plate and the fixed mold 3, since the surfaces of the two movable plates 28 at one end away from the rotating plates 32 are provided with rubber pads, direct friction with the fixed mold 3 can be avoided to cause damage to the mold; with the help of the telescopic ends of the hydraulic cylinders 11 at the bottom of the two processing tables 5 extending upward, the two movable plates 28 located on both sides of the automobile battery guard plate are driven to move upward together, and the automobile battery guard plate stuck in the fixed mold 3 is pushed upward and removed, so as to avoid affecting the subsequent stamping work of the automobile battery guard plate.

[0035] Since the four edge positions of the automobile battery guard plate need to be processed with flanges during the stamping process to facilitate its subsequent installation, the flanges of the automobile battery guard plate also need to be trimmed with the help of other processing equipment for the slight deformation and negative angle caused by its stamping process. In order to improve the processing efficiency of the entire automobile battery guard plate, the telescopic ends of the two sets of second electric telescopic rods 13 can be controlled to extend, driving the two first shaping plates 6 to move in a direction close to each other, clamping and fixing the two ends of the stamped automobile battery guard plate, and then with the help of the upward extension of the telescopic ends of the two sets of first electric telescopic rods 12, the clamped automobile battery guard plate is driven to move upward to a height away from the fixed mold 3, and then the two adding The work tables 5 move towards the approaching direction and dock with each other, and the bottom auxiliary supports of the two processing tables 5 are connected with the help of two limit blocks 25 arranged below. At this time, the two connected processing tables 5 are located between the movable mold 2 and the fixed mold 3, and the telescopic ends of the two corresponding second electric telescopic rods 13 can be controlled to retract, driving the two first shaping plates 6 to release the clamping of the automobile battery guard plate above the processing tables 5, so that the automobile battery guard plate falls downward and is placed on the top of the two processing tables 5. Then, the telescopic ends of the two groups of second electric telescopic rods 13 can be controlled to extend again, driving the first shaping plate 6 and the second shaping plate 4 to move together to the inside of the automobile battery guard plate, and the telescopic ends of the two groups of first electric telescopic rods 12 can be retracted. The two upper pressing blocks 10 are then controlled to rotate downward to the bottom of the movable mold 2. With the downward movement of the movable mold 2, the two upper pressing blocks 10 are driven to press the top ends of the two second shaping plates 4 respectively. At this time, the two clamping blocks 14 can prevent the pressed second shaping plates 4 from being distorted. The mounting plate 19 is inclined so that after being squeezed, it drives the second shaping plate 4 to continue to move toward the position close to the flange, thereby converting the vertical downward force into a horizontal force, and squeezing and pushing the negative angle position produced by the inward deformation of the flange of the automobile battery guard plate to shape it, so that there is no need to transport the automobile battery guard plate to other equipment for processing, thereby improving the efficiency of stamping and forming of automobile covering parts; when the top of the first shaping plate 6 is not under force, it can be reset by means of the elasticity of multiple springs 20, driving the first shaping plate 6, the second shaping plate 4 and other multiple components to reset together, thereby achieving the effect of self-balancing reset of the first shaping plate 6 and the second shaping plate 4.

[0036] When the vertical force is converted into horizontal force with the help of the first shaping plate 6 to drive the second shaping plate 4 to shape the flange position of the automobile battery guard plate, the two rotating plates 32 can be driven to move in a direction close to each other with the help of the connecting blocks 27 on both sides of the two processing tables 5, and the other two sides of the automobile battery guard plate placed on the top of the processing table 5 can be clamped and fixed, so as to facilitate the flanging shaping work of the two second shaping plates 4; and the two first sliding blocks 16 can also be controlled to move back and forth inside the corresponding first slide groove 15, so as to drive the positions of the rectangular plate 9, the two clamping blocks 14, the first shaping plate 6 and the second shaping plate 4 to be adjusted, so as to facilitate the adjustment of the flanging shaping range of the automobile battery guard plate.

[0037] Furthermore, after the two second shaping plates 4 shape the flange positions on both sides of the automobile battery guard plate, the telescopic ends of the two sets of first electric telescopic rods 12 are controlled to drive the first shaping plate 6 and the second shaping plate 4 to move upward to a height away from the automobile battery guard plate. At this time, the two connecting blocks 27 can be controlled to drive the two rotating plates 32 to move in a direction away from the automobile battery guard plate, and then the two rotating plates 32 are controlled to rotate to a horizontal state, and then the two rotating plates 32 in a horizontal state are controlled to rotate in a direction close to each other to just above the automobile battery guard plate, and finally the two rotating plates 32 are controlled to drive the two moving plates 28 to rotate downward to the height of the automobile battery guard plate. Inside, the two movable plates 28 are located at the bottom of the rotating plate 32 at this time, and the two movable plates 28 are controlled to move in the direction of moving away from each other, so that the ends of the two movable plates 28 that are away from each other are respectively in contact with the two side flanges after shaping. As the two rotating plates 32 are controlled to move back and forth, the ends of the two movable plates 28 that are away from each other are driven to rub against the two side flanges after shaping, and the flanges after shaping of the second shaping plate 4 are detected. If the two movable plates 28 are not smooth during the movement process, or cannot continue to move after moving to a certain position, there is still deformation in this part that cannot be completely processed, and the second shaping plate 4 can continue to be controlled to continue shaping this position.

[0038] After processing the negative deformation angles on the two side flanges of the automobile battery guard plate, the two rotating plates 32 can be controlled to rotate and reset from the inside of the automobile battery guard plate. At this time, the electromagnets at the top of the two electric sliders 31 can be controlled to adsorb and fix the bottom end of the automobile battery guard plate, and the two electric sliders 31 can be controlled to move in one direction inside the corresponding arc groove 29, thereby driving the automobile battery guard plate to rotate and adjust, and using the two rotating plates 32 moving in the direction close to each other to push the two ends after rotation, so that after the automobile battery guard plate is rotated and adjusted, the unprocessed flanges on the other two sides are respectively rotated to the position close to the two first shaping plates 6, and the above-mentioned steps of shaping the flanges are repeated, so that the negative deformation angles on the flanged parts of the automobile battery guard plate can be comprehensively processed, so as to improve the overall processing efficiency of the automobile battery guard plate.

[0039] After the four flanges of the automobile battery guard plate are fully processed, the external preset manipulator can be controlled to turn over the automobile battery guard plate on the top of the two processing tables 5. At this time, the automobile battery guard plate is placed on the top of the two processing tables 5 in an upside-down shape, and the telescopic ends of the two groups of first electric telescopic rods 12 are controlled to drive the first shaping plate 6 and other multiple components to move upward together, and the telescopic ends of the two groups of second electric telescopic rods 13 are controlled to extend, so as to drive the two first shaping plates 6 to move above the edge positions on both sides of the automobile battery guard plate respectively, and finally, with the help of the telescopic ends of the two groups of first electric telescopic rods 12 to retract downward, the bottom ends of the two first shaping plates 6 are driven to respectively face the automobile battery guard plate. Two edges of the battery guard plate are pressed and shaped. After the two edge positions are shaped, the battery guard plate is rotated and reset by controlling an external manipulator, and its position is rotated and adjusted by means of two electric sliders 31 and electromagnets, and it is turned over by means of a manipulator, and the other two edge positions are pressed and shaped continuously; and in the process of shaping, the two first sliders 16 can also be used to move back and forth inside the first slide groove 15 to adjust the position of the first shaping plate 6, so as to facilitate the processing of the upward deformation caused by stamping the edge position of the battery guard plate, thereby further improving the forming efficiency of the battery guard plate.

[0040] When the fixed mold 3 needs to be inspected and maintained after being used for a period of time, the two processing tables 5 can be controlled to move towards each other, and with the help of the telescopic ends of the two groups of hydraulic cylinders 11 below, the two processing tables 5 can be driven to move upward until the tops of the two processing tables 5 abut against the two upper pressing blocks 10 at the bottom of the movable mold 2. At this time, the two processing tables 5 cooperate with the two groups of hydraulic cylinders 11 set at the bottom to support and limit the upper movable mold 2, thereby preventing the staff from accidentally touching the switch during the inspection of the fixed mold 3, causing the movable mold 2 to move downward, causing injuries to the staff, and further improving the safety of the staff in inspecting the fixed mold 3.
