[0020] Please refer to Figures 1 - 2 , Figure 1 It is a structural diagram of a hydroforming mechanism 110 for processing automobile seat parts according to the first embodiment of the present utility model. Figure 2 It is a schematic cross-sectional view of a hydroforming mechanism 110 for processing automobile seat parts according to the first embodiment of the present utility model.

[0021] The present utility model provides a hydroforming mechanism for processing automobile seat parts: including a hydraulic press 101 and a demoulding assembly 102. The demoulding assembly 102 includes a bottom plate 103, a gantry 104, a mounting plate 105, an upper die 106, a lower die 107, a workbench 108, a spring column 109, a limiting mechanism 110, a cylinder 111, a limiting plate 112, an inner rod 113, an outer rod 114, a spring 115, a support plate 116 and a slide bar 117. By the foregoing solution, the problem that after stamping is completed by the existing device, the parts are easily attached to the die, resulting in inconvenient demoulding of the device and low processing efficiency is solved.

[0022] In this embodiment, the hydraulic press 101 is controlled by a hydraulic system and is used for hydraulic stamping of parts.

[0023] Among them, the gantry 104 is connected to the hydraulic press 101 and is located on one side of the hydraulic press 101. The workbench 108 is fixedly connected to the gantry 104 and is located on one side of the gantry 104. The mounting plate 105 is fixedly connected to the output end of the hydraulic press 101 and is located on one side of the hydraulic press 101. The upper die 106 is detachably connected to the mounting plate 105 and is located on one side of the mounting plate 105. The spring 109 is connected to the workbench 108 and is located on the top of the workbench 108. The bottom plate 103 is connected to the spring column 109 and is located on the top of the spring column 109. The lower die 107 is detachably connected to the bottom plate 103 and is located on one side of the bottom plate 103. The upper die 106 is installed on the mounting plate 105, and the lower die 107 is installed on the bottom plate 103. The hydraulic press 101 drives the upper die 106 to stamp the lower die 107. During the stamping process, the spring column 109 undergoes vertical telescopic deformation. After the stamping is completed, the hydraulic press 101 quickly retracts the upper die 106, and the lower die 107 rebounds through the spring column 109, so that the parts on the lower die 107 are loosened when the spring column 109 rebounds, preventing the parts from adhering to the lower die 107 and facilitating the removal of the parts. The limiting mechanism 110 is used to limit the position of the plate, solving the problem that in the existing device, after stamping is completed, the parts are easily attached to the die, resulting in inconvenient demoulding of the device and low processing efficiency.

[0024] Secondly, the limiting mechanism 110 includes a cylinder 111 and a limiting plate 112. The cylinder 111 is fixedly connected to the workbench 108 and is located on the top of the workbench 108. The limiting plate 112 is fixedly connected to the output end of the cylinder 111 and is located on one side of the cylinder 111. The cylinder 111 drives the limiting plate 112 to limit the plate for stamping parts in the middle of the lower die 107.

[0025] Thirdly, the spring 109 includes an inner rod 113, an outer rod 114 and a spring 115. The inner rod 113 is fixedly connected to the bottom plate 103 and is located at the bottom of the bottom plate 103. The outer rod 114 is slidably connected to the inner rod 113 and is located on the outside of the outer rod 114. The spring 115 is connected to the workbench 108 and is also connected to the bottom plate 103 and is located between the workbench 108 and the bottom plate 103. During the stamping process of the spring column 109, the inner rod 113 slides inside the outer rod 114, and the bottom plate 103 is rebounded and reset by the spring 115.

[0026] Finally, the demolding assembly 102 further includes a support plate 116 and a slide bar 117. The support plate 116 is fixedly connected to the workbench 108 and is located at the bottom of the bottom plate 103. The slide bar 117 is slidably connected to the bottom plate 103 and is located on one side of the bottom plate 103. The slide bar 117 is fixedly connected to the workbench 108 and is located on one side of the workbench 108. The support plate 116 has the same height as the outer rod 114 to prevent the outer rod 114 from being unable to withstand the stamping of the hydraulic press 101 during stamping. The slide bar 117 restricts the bottom plate 103 to move only up and down to prevent the bottom plate 103 from shaking left and right.

[0027] When using a hydraulic forming mechanism for processing automotive seat parts of the present utility model, the hydraulic press 101 is controlled by a hydraulic system and is used for hydraulic stamping of parts. The upper die 106 is installed on the mounting plate 105, and the lower die 107 is installed on the bottom plate 103. The hydraulic press 101 drives the upper die 106 to stamp the lower die 107. During the stamping process, the spring column 109 undergoes up and down telescopic deformation. After the stamping is completed, the hydraulic press 101 quickly retracts the upper die 106, and the lower die 107 rebounds through the spring column 109, causing the parts on the lower die 107 to be loosened when the spring column 109 rebounds to prevent the parts from adhering to the lower die 107, facilitating the removal of the parts. The limiting mechanism 110 is used to limit the position of the sheet material, solving the problem that in the prior art, after stamping is completed, the parts are easily attached to the die, resulting in inconvenient demolding of the device and low processing efficiency.

[0030] The dust collector 201 is fixedly connected to the workbench 108 and is located on one side of the workbench 108. The corrugated pipe 202 is connected to the dust inlet of the dust collector 201 and is located on one side of the dust collector 201. The dust collector 201 is used to absorb dust or particles on the device to prevent impurities from affecting the stamped parts. The corrugated pipe 202 facilitates the control of the dust inlet of the dust collector 201.
