[0032] Please refer to Figures 2-7 The utility model provides a pressure forming device, including oil press 1, fixed assembly and buffer support component. Among them, oil press 1 includes body 10, upper die 11, lower die 12 and power unit 13, power unit 13 sets up on body 10 and is driven to be connected with upper die 11, is used for driving upper die 11 to go up and down. Lower die 12 is fixed on the worktable surface of body 10, and the upper surface of lower die 12 has protrusion 121, the upper surface of lower die 12 has flanging forming cavity 120, flanging forming cavity 120 is located at the periphery of protrusion 121 along the circumference of protrusion 121, upper die 11 has the recess of containing protrusion 121, and the periphery of recess has the forming block corresponding with flanging forming cavity 120.
[0033] It needs to be explained that power unit 13 is the power structure of the existing oil press 1, and upper die 11 and lower die 12 are also the existing die structure on the oil press 1, which will not be repeated here.
[0034] Among them,Figure 8 Fig. 2 is a structural schematic view of the door panel 5 involved in the present embodiment.
[0035] In the present embodiment, the width direction of the machine body 10 is the horizontal first direction, the length direction of the machine body 10 is the horizontal second direction, and the two sides of the door panel 5 placed on the lower mold 12 extend out of the lower mold 12 along the horizontal first direction. To this end, the part of the door panel 5 located outside the lower mold 12 is supported by the buffer support assembly arranged on the fixed assembly, so as to avoid uneven force on the door panel 5 and affect the forming quality of the door panel 5.
[0036] In the present embodiment, the fixed assembly includes two mounting racks 2 arranged on the machine body 10 and respectively located on the opposite sides of the workbench top along the horizontal first direction, and the buffer support assembly includes a brush table 3 and an elastic buffer 31, and the elastic buffer 31 is arranged between the brush table 3 and each mounting rack 2. Of course, the brush table 3 is provided with a clearance 30 for avoiding the lower mold 12, so as to avoid interference between the brush table 3 and the lower mold 12.
[0037] Specifically, before the upper mold 11 is not pressed down, the upper surface of the brush table 3 is higher than the surface of the lower mold 12, the upper surface of the brush table 3 is lower than the lower surface of the protrusion 121, and the distance between the upper surface of the brush table 3 and the upper surface of the lower mold 12 is set as D, which is in the range of 2-5 mm, and D of the present embodiment is 2 mm. Since the brushes on the brush table 3 are flexible, the upper surface of the brush table 3 is set to be higher than the surface of the lower mold 12, so as to avoid the upper surface of the brush table 3 and the upper surface of the lower mold 12 being not flush due to the gravity of the door panel 5. That is to say, it can be understood that after the brush table 3 is subjected to the gravity of the door panel 5, the upper surface of the brush table 3 is flush with the upper surface of the lower mold 12, so as to make the door panel 5 balanced after being pressed.
[0038] Of course, in other embodiments, D can also be 4 mm or 5 mm, which is not limited here.
[0039] The utility model discloses a pressure forming device, which comprises a machine body 10, a plurality of installation frames 2, a plurality of brush tables 3, a plurality of power units 13, a plurality of upper dies 11 and a plurality of lower dies 12.
[0040] In the embodiment, the installation frame 2 is slidably arranged on the machine body 10 along a horizontal second direction, so that the installation frame 2 can slide into or out of the workbench of the machine body 10. Specifically, the guide rails 4 are fixed on the two side walls of the machine body 10 along the horizontal first direction, and extend along the horizontal second direction. Each installation frame 2 is slidably connected with each guide rail 4, so that each installation frame 2 can slide along each guide rail 4. In this way, the brush table 3 can be conveniently slid into or out of the workbench, and the door plate 5 to be processed can be conveniently taken out or placed. Of course, in order to avoid the influence of the lower die 12 on the sliding of the brush table 3 into or out of the workbench along the horizontal second direction, the above-mentioned empty portion 30 penetrates through the brush table 3 along the direction in which the installation frame 2 slides into the workbench.
[0041] In the embodiment, with reference to Figure 2 or Figure 3 , the guide rail 4 does not extend outside the machine body 10, so that the space can be saved, and the space occupied by the guide rail 4 extending outside the machine body 10 along the horizontal second direction and the influence on the work of the operator can be avoided, thereby effectively improving the safety of the working environment.
[0042] Of course, the guide rail 4 has a stop portion 40 at both ends, which is used to prevent the sliding seat from being separated from the guide rail 4.
[0043] In the embodiment, with reference to Figure 6When the upper die 11 presses the door plate 5, the front part of the brush table 3 extends out of the workbench surface in the horizontal second direction, so that the contact area of the brush table 3 and the door plate 5 is increased, and the supporting force of the brush table 3 on the door plate 5 is improved. Since the guide rail 4 cannot extend out of the machine body 10, the mounting frame 2 is arranged at an angle with the guide rail 4, that is, on the basis of the sliding connection between the mounting frame 2 and the guide rail 4, the included angle between the mounting frame 2 and the guide rail 4 is an acute angle, so that the front part of the brush table 3 extends out of the workbench surface in the horizontal second direction, and the guide rail 4 does not extend out of the machine body 10, thereby achieving the effect of saving space.
[0044] In the embodiment, the included angle between the mounting frame 2 and the guide rail 4 is angle A, and the range of angle A is 30-45°. In the embodiment, angle A is 30°, so that the stroke of the brush table 3 sliding out of the workbench surface in the horizontal second direction is not affected by the too large included angle between the mounting frame 2 and the guide rail 4. Of course, in other embodiments, angle A can also be 45° or 35°, which is not limited herein. It can be understood that under the condition that the length direction of the guide rail 4 is certain, the above-mentioned angle A can be reasonably changed according to the actual situation to meet the stroke of the brush table 3 sliding out of the workbench surface in the horizontal second direction.
[0045] In the embodiment, the elastic supporting member is a spring plunger as the accompanying lifting core accessory of the brush table 3, so that the built-in spring force can be adjusted according to the actual needs to meet the on-site needs. Of course, in other embodiments, the elastic buffer 31 can also be a spring, which is not limited herein.
[0046] It should be noted that the spring plunger can adjust the supporting force of the brush table according to the weight of the workpiece supported by the brush table 3, so that the pressure forming device of the utility model can be applied to workpieces of different weights, and the universality of the pressure forming device of the utility model is greatly improved. In addition, when the pressure forming device of the utility model is used, since the brush table 3 supports the door plate 5 to be processed, only one person is needed to operate. When the oil press is used to turn up the holes on the door plate 5, since the size of the door plate 5 is larger than the size of the lower die 12, the opposite two sides of the door plate 5 extend beyond the two sides of the lower die 12, so at least two people are needed to hold the two sides of the door plate 5 extending out of the lower die 12. Therefore, compared with the prior art, the use of the pressure forming device of the utility model saves labor.
[0047] The above-mentioned is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion obtained by using the content of the utility model specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection range of the utility model.
