Description

Technical Field:

[0001] The present invention relates to the technical field of magnesium alloy automobile parts, and more specifically to a hydraulic hot forming device for an automobile instrument panel skeleton with convenient disassembly and assembly of molds. Background Art:

[0002] Existing automobile instrument panel brackets are generally made of magnesium alloy by casting. Casting is to pour molten metal into a mold and solidify it. Due to factors such as the cooling rate and the physical properties of the metal, the geometric accuracy and surface quality of the casting products are relatively poor.

[0003] For existing automobile instrument panel brackets, the surface accuracy requirements are relatively high, so that after casting, the surface does not need to be machined anymore. Therefore, some existing methods are to use hydraulic hot forming to manufacture. Hydraulic hot forming is a forming method in which the material is heated to make it softened and then pressure is applied to deform the material into the required shape. It can meet the high surface accuracy requirements of automobile instrument panel brackets. However, in existing forming molds, the upper mold and the lower mold are both fixed to the connecting plate by bolts, and then the connecting plate is fixed to the mold connecting piece. Due to its heavy weight, a crane is required for lifting. And due to structures such as the stamping cylinder above the upper mold, it cannot be placed from top to bottom to the required installation position, but needs to be lifted and moved to the front or rear of the installation position, and then manually pushed to the installation position and installed. After reaching the front or rear of the installation position, manual pushing is required. Its installation is troublesome, the loading and unloading are troublesome, the efficiency is low, and the effect is poor.

[0004] There are also some that directly carry the connecting plate with the upper mold or the lower mold installed by multiple people to the installation position for installation. Its efficiency is low, the effect is poor, and the manual labor intensity is large. Summary of the Invention:

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a hydraulic hot forming device for an automobile instrument panel skeleton with convenient disassembly and assembly of molds. It can place the upper mold mounting plate with the upper mold and the lower mold mounting plate with the lower mold on the flipping support plate, and it can automatically move the upper mold mounting plate or the lower mold mounting plate to the corresponding upper heating block or heating fixing block for installation.

[0028] Figure 5 is Figure 4 a partial enlarged view of... Specific implementation manner:

[0029] In the embodiment, as shown in... Figures 1 to 5 shown, a hydraulic hot shaping device for an automotive instrument panel skeleton with convenient die disassembly and assembly includes a forming frame 10 and a die replacement auxiliary frame 20. On the top surface of the top plate of the forming frame 10, an upper support frame 30 is fixed. In the middle of the top surface of the top plate of the forming frame 10, a heating fixing block 11 is fixed. A plurality of heating rods 111 are installed in the heating fixing block 11. The top surface of the heating fixing plate 11 is fixedly connected to a lower die mounting plate 12 by bolts. The lower die 13 is fixed on the top surface of the lower die mounting plate 12 by bolts;

[0030] In the middle of the top surface of the top plate of the upper support frame 30, a forming oil cylinder 31 is fixed. The bottom end of the push rod of the forming oil cylinder 31 extends out of the top surface of the top plate of the upper support frame 30 and is fixed to a lifting fixing plate 32. The bottom surface of the lifting fixing plate 32 is fixedly connected to an upper heating block 33 by bolts. A plurality of heating rods 331 are installed in the upper heating block 33;

[0031] The bottom surface of the upper heating block 33 is fixedly connected with an upper die mounting plate 34 through bolts, and the bottom surface of the upper die mounting plate 34 is fixedly connected with an upper die 35 through bolts. The upper die 35 and the lower die 13 are corresponding up and down.

[0032] The die replacement auxiliary frame 20 is located behind the forming frame 10 and fixed on the ground. The front wall surface of the flipping support plate 21 of the die replacement auxiliary frame 20 is close to the rear wall surface of the forming frame 10.

[0033] Furthermore, vertical guide columns 14 are fixedly arranged at the front and rear parts of the left and right sides of the top surface of the top plate of the forming frame 10. The bottom ends of the vertical guide columns 14 are fixedly arranged on the top plate of the upper support frame 30. Vertical guide through holes are formed at the front and rear parts of the left and right sides of the lifting fixing plate 32. The outer side wall of the guide sleeve is pressed against the inner side wall of the corresponding vertical guide through hole. The guide sleeve is fixedly arranged on the lifting fixing plate 11. The vertical guide column 14 is inserted into the corresponding guide sleeve, and the outer side wall of the vertical guide column 14 is closely attached to the inner side wall of the corresponding guide sleeve to achieve cooperation.

[0034] A plurality of dovetail-shaped through grooves 112 extending in the front and rear directions are formed on the top surface of the heating fixing block 11, and a plurality of dovetail-shaped guide strips 113 extending in the front and rear directions are formed on the top surface of the heating fixing block 11. A plurality of first dovetail-shaped through grooves 121 extending in the front and rear directions and a plurality of first dovetail-shaped guide strips 122 extending in the front and rear directions are formed on the bottom surface of the lower die mounting plate 12. The first dovetail-shaped guide strip 122 is inserted into the corresponding dovetail-shaped through groove 112 and cooperates with it, and the dovetail-shaped guide strip 113 is inserted into the corresponding first dovetail-shaped through groove 121 and cooperates with it.

[0035] Adopting the above structure increases the contact area between the heating fixing block 11 and the lower die mounting plate 12, improves the heat conduction effect, and the cooperation of the dovetail-shaped guide strip 113, the first dovetail-shaped guide strip 122, the first dovetail-shaped through groove 121 and the dovetail-shaped through groove 112 makes the two not easy to shift, the installation and fixation are accurate, and it is convenient to fixedly connect with bolts subsequently.

[0036] A plurality of second dovetail-shaped through grooves 331 extending in the front and rear directions and a plurality of second dovetail-shaped guide strips 332 extending in the front and rear directions are formed on the bottom surface of the upper heating block 33. A plurality of third dovetail-shaped through grooves 341 extending in the front and rear directions and a plurality of third dovetail-shaped guide strips 342 extending in the front and rear directions are formed on the top surface of the upper die mounting plate 34. The second dovetail-shaped guide strip 332 is inserted into the corresponding third dovetail-shaped through groove 341 and cooperates with it, and the third dovetail-shaped guide strip 342 is inserted into the corresponding second dovetail-shaped through groove 331 and cooperates with it.

[0037] Similarly, adopting the above structure increases the contact area between the upper heating block 33 and the upper die mounting plate 34, improving the heat conduction effect. Moreover, the cooperation of the second dovetail-shaped through groove 331, the second dovetail-shaped guiding strip 332, the third dovetail-shaped through groove 341 and the third dovetail-shaped guiding strip 342 makes it difficult for the two to shift, ensuring accurate installation and fixation, and facilitating subsequent bolted connection.

[0038] Furthermore, on the left and right parts of the top surface of the upper heating block 33, support blocks 335 extending upward are fixed or formed. The support blocks 335 are inserted into corresponding vertical through holes in the lifting fixed plate 32. The upper part of the support block 335 extends out of the top surface of the lifting fixed plate 32 and is formed with a positioning through groove 336 penetrating left and right. On the top surface of the lifting fixed plate 32 at one side of the upper part of the support block 335, a pushing oil cylinder 36 is fixed. The end of the push rod of the pushing oil cylinder 36 is fixed with a pushing block 37. The horizontal part of the pushing block 37 is inserted into the corresponding positioning through groove 336.

[0039] A self-lubricating plate 372 is fixed to the bottom surface of the horizontal part of the pushing block 37. A lateral guiding strip 325 is fixed to the corresponding position on the top surface of the lifting fixed plate 32. The lateral guiding strip 325 is inserted into a left-and-right extending guiding groove formed on the bottom surface of the corresponding self-lubricating plate 372.

[0040] On the top plate of the upper support frame 30 above the pushing oil cylinder 36 and the corresponding support block 335, an upper through groove 38 extending left and right is formed. When the lifting fixed plate 32 is lifted, the pushing oil cylinder 36 and the corresponding support block 335 will be at the corresponding upper through groove 38, preventing them from colliding with and interfering with the top plate of the upper support frame 30.

[0041] Adopting the above structure, when the upper heating block 33 needs to be disassembled, replaced or repaired, after the bolts between the upper heating block 33 and the lifting fixed plate 32 are disassembled, it will not fall. Support is achieved through the horizontal parts of the two pushing blocks 37, thus preventing the upper heating block 33 from directly falling after the bolts between it and the lifting fixed plate 32 are disassembled, improving the safety effect. Subsequently, only a forklift or other lifting equipment is needed to extend the horizontal support part under the upper heating block 33 and lean it against the top surface of the upper heating block 33, lift it upward by a small distance to ensure that the top surface of the positioning through groove 336 does not lean against the top surface of the horizontal part of the pushing block 37. Then, by retracting the push rods of the two pushing oil cylinders 36, the horizontal parts of the pushing blocks 37 are removed from the corresponding positioning through grooves 336. At this time, the upper heating block 33 is completely separated from the lifting fixed plate 32. Then, by lowering the horizontal support part with the forklift or other lifting equipment, the upper heating block 33 will descend with the horizontal support part and can be removed for repair or replacement, which is very convenient.

[0042] Furthermore, the die replacement auxiliary frame 20 includes a lower support frame 22, and a lifting mechanism is installed on the lower support frame 22;

[0043] The lifting mechanism includes a middle vertical screw column 50.

Vertical guide columns are fixed at the front, rear, left, and right parts of the bottom surface of the horizontal lifting fixing plate 23. The vertical guide columns are inserted into the corresponding guide sleeves.

[0044] By operating the lifting servo motor 54, the horizontal lifting fixing plate 23 can be adjusted in height. The limit nut 52 can prevent the horizontal lifting fixing plate 23 from being lifted excessively. By pressing the top surface of the limit nut 52 against the bottom surface of the rotating screw sleeve 51, it is limited so that it will not be lifted anymore.

[0045] Meanwhile, a vertical fixing rod is fixed on the top surface of the top plate of the lower support frame 22. A limit proximity switch 60 is fixed on the upper side wall of the vertical fixing rod. Correspondingly, a vertical screw rod 61 is fixed on the bottom surface of the horizontal lifting fixing plate 23.

Ring-shaped protruding rings extending outwards are formed on the outer side walls of the first adjusting screw sleeve 62 and the second adjusting screw sleeve 63, and they are close to the sensing end of the limit proximity switch 60. In use of this structure, when installing the lower die 13, the sensing end of the limit proximity switch 60 is close to the outer side wall of the ring-shaped protruding ring of the first adjusting screw sleeve 62 to achieve sensing; when installing the upper die 35, the sensing end of the limit proximity switch 60 is close to the outer side wall of the ring-shaped protruding ring of the second adjusting screw sleeve 63 to achieve sensing.

[0056] At the same time, all the electrical equipment in this embodiment is electrically connected to the control host through electrical connection lines and is controlled by the control host to operate. It has a conventional structure and will not be elaborated here.

[0057] When this embodiment is in use, the casting of the automotive instrument panel bracket to be processed and formed is placed on the lower die 13. The heating rod 111 in the heating fixed block 11 is used for heating, so that the lower die mounting plate 12 is heated, and then the heat is transferred to the lower die 13, making the casting of the automotive instrument panel bracket on it heated and softened. At the same time, the heating rod 331 in the upper heating block 33 is also heated, so that the upper die mounting plate 34 is heated, and then the upper die 35 is also heated and raised in temperature. Then, through the pushing of the push rod of the forming oil cylinder 31, the upper die 35 descends, so that the casting of the automotive instrument panel bracket is located between the upper die 35 and the lower die 13 to form a formed casting.

[0058] Among them, stoppers are fixed on the front wall surfaces of the heating fixed block 11 and the upper heating block 33.

[0059] When it is necessary to replace the upper die 35 and the lower die 13, such as when replacing the lower die 13, first turn the top surface of the flipping support plate 21 upwards, remove the bolts connecting the lower die mounting plate 12 and the heating fixing plate 11, and then push the lower die mounting plate 12 (which is connected to the lower die 13 and is pushed out simultaneously) backward until it reaches the top surface of the flipping support plate 21 (at this time, the front limit block 2 and the rear limit block 3 are pulled out from the flipping support plate 21), and then use a crane to take it out together with the lower die 13 on the lower die mounting plate 12;

[0060] When disassembling the upper die 35, the lifting servo motor 54 is operated to adjust the height position of the horizontal lifting fixing plate 23 until the top surface of the flipping support plate 21 is basically flush with the bottom surface of the upper die 35 (at this time, the lifting servo motor 54 is manually controlled and is not affected by the induction of the induction end of the limit proximity switch 60). Then, the bolts connecting the upper die mounting plate 34 and the bottom surface of the upper heating block 33 are removed, and then the upper die mounting plate 34 is pushed backward to the top surface of the flipping support plate 21 to achieve disassembly, which is very convenient.

[0061] When installing the lower die 13, first use a crane to place the lower die mounting plate 12 with the lower die 13 installed on the top surface of the flipping support plate 21, transfer four side adjustment bolts 216, so that the self-lubricating wear-resistant layer fixed on the inner side wall of the side adjustment guide block 214 closely adheres to the left or right side wall of the lower die mounting plate 12. At the same time, the upper limit plate part 215 is above the edge of the lower die 13. At this time, the left and right side walls of the lower die mounting plate 12 are aligned with the straight lines extending forward and backward of the corresponding positioning marks 9;

[0062] At this time, the sensing end of the limit proximity switch 60 senses the annular raised ring of the first adjusting sleeve 62, and the top surface of the flipping support plate 21 is on the same horizontal plane as the bottom surface of the dovetail-shaped through groove 112 formed by the top surface of the heating fixing block 11 (it can have an error of about 1 mm to 2 mm. When the gap between the two is large, it is necessary to manually control the lifting servo motor 54 to operate to change the height position of the top surface of the flipping support plate 21 to ensure accurate positioning). Then, manually operate the control button of the control host to make the moving motor 412 operate, so that the transverse support plate 42 moves forward, so that the horizontal pushing plate 46 moves forward, and its front end leans against the rear wall surface of the lower die 13 and the lower die mounting plate 12. Then, manually control the control button of the control host to make the moving motor 412 stop operating. Then, press the control button to make the push rod of the pushing oil cylinder 44 push, and move the lower die 13 and the lower die mounting plate 12 forward, so that the first dovetail-shaped guide bar 122 is inserted into the corresponding dovetail-shaped through groove 112 and cooperates with it, and the dovetail-shaped guide bar 113 is inserted into the corresponding first dovetail-shaped through groove 121 and cooperates with it until the front wall surface of the lower die mounting plate 12 leans against the front stop block to complete the installation. Subsequently, only bolt fixation is required. Its installation is convenient, without manual lifting, greatly reducing the manual labor intensity.

[0063] When installing the upper die 35, the upper die mounting plate 34 with the upper die 35 installed is placed on the top surface of the flipping support plate 21. Similar to before, manually adjust the four side adjusting bolts 216 to make the self-lubricating wear-resistant layer fixed on the inner side wall of the side adjusting guide block 214 closely adhere to the left side wall or the right side wall of the upper die mounting plate 34 to achieve limiting. Then, install the front limiting block 2 and the rear limiting block 3. Pull out the inner ends of the two pins 6 from the corresponding concave holes. Then, through the operation of the servo rotating motor 213, flip the flipping support plate 21 by 180 degrees. At this time, the upper die mounting plate 34 is above and the upper die 35 is below. Then, through the operation of the lifting servo motor 54, lift the flipping support plate 21 until the sensing end of the limit proximity switch 60 senses the annular raised ring of the second adjusting sleeve 63, indicating that its movement is in place. At this time, the top surface of the upper die mounting plate 34 is on the same horizontal plane as the top surface of the second dovetail-shaped through groove 331 formed by the bottom surface of the upper heating block 33. If there is still a large gap between the two, it is necessary to manually control the lifting servo motor 54 to operate to adjust the height position of the flipping support plate 21 to ensure that the top surface of the upper die mounting plate 34 is on the same horizontal plane as the top surface of the second dovetail-shaped through groove 331 formed by the bottom surface of the upper heating block 33, or the gap between the two is controlled within about 1 mm to 2 mm. Then, insert the inner ends of the two pins 6 into the concave holes of the corresponding rear positioning posts 8 to achieve positioning. Remove the front limiting block 2 and the rear limiting block 3. Then, in the same way as installing the lower die 13 and the lower die mounting plate 12, it can be done. The installation is convenient, the installation effect is good, the efficiency is high, and the manual labor intensity is greatly reduced.
