Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, and particularly relates to a composite material hydraulic press. Background Art

[0002] A hydraulic press is a mechanical device that uses hydrostatic pressure for energy transfer to achieve various processing technologies. The hydraulic press uses an oil pump as a power driving device and uses oil as a driving medium. Driven by the oil pump, the oil passes through a pipeline and is connected to a hydraulic cylinder, thereby pushing a working component at the end of the hydraulic cylinder to process a workpiece.

[0003] Currently, when making workpieces using fiberglass composite materials, experienced workers or fully automatic machines are generally used to repeatedly wind fiberglass on a mold to achieve the required outer shape structure of the workpiece. The composite material products obtained by winding usually still have an unstable structure and need to be pressed and formed by a hydraulic press and then baked at a high temperature for shaping after demolding. During the pressing process of the hydraulic press, a hydraulic cylinder of the hydraulic press is used to push an inflatable and expandable upper mold into the interior of the composite material product, and the extrusion force generated by the air pressure expansion extrudes the inner wall of the composite material product outward to complete the shaping. However, during the extrusion molding process, there is no protective structure around the punching table of the hydraulic press. After impurities other than the mold and the composite material product enter the internal cavity of the composite material product, the structure of the workpiece obtained after pressing is damaged by the impurities, resulting in defective products and affecting the production quality.

[0025] The present utility model provides a Figures 1 - 5 shown composite material hydraulic press, which includes a workbench 1, a controller 6 is arranged on the top of the workbench 1, a stamping table 4 is also arranged on the top of the workbench 1, a hydraulic cylinder 11 is arranged above the stamping table 4, a stroke slider 10 is arranged at the end of the hydraulic cylinder 11, a connecting column 81 is arranged at the bottom of the stroke slider 10, a stamping upper die 8 is fixed at the bottom end of the connecting column 81, a stamping bottom die 5 is arranged inside the stamping table 4, the top end of the stamping bottom die 5 exposes from the top of the stamping table 4, a slot 51 is arranged inside the workbench 1 near the outside of the stamping bottom die 5, a clamping groove 52 is arranged at the bottom extension end of the slot 51, a protection component is also arranged at the bottom of the stroke slider 10, the protection component includes an outer sleeve 91 sleeved outside the stamping upper die 8, an airbag clamp 9 is connected to the bottom end of the outer sleeve 91, and a connecting pipe 151 is arranged between the outer sleeve 91 and the connecting column 81;

[0026] A connecting pipe 151 is provided between the connecting column 81 and the airbag snap ring 9. On one side of the top end of the connecting column 81, an air inlet pipe 15 is provided. The extending end of the air inlet pipe 15 penetrates through the stroke slider 10 and extends to the outside of the stroke slider 10. Specifically, both the airbag snap ring 9 and the connecting column 81 are hollow structures. A hydraulic device can be connected to the extending end of the air inlet pipe 15. The hydraulic device provides compressed gas. The compressed gas passes through the air inlet pipe 15, then enters the connecting column 81, then passes through the connecting pipe 151, and then enters the airbag snap ring 9 and the stamping upper die 8. After the stamping upper die 8 is filled with gas, it bulges. Before that, the telescopic end of the hydraulic cylinder 11 pushes the stroke slider 10 downward and pushes the outer sleeve 91 and the airbag snap ring 9 downward. Figure 1 The stamping upper die 8 in Figure 1 is in a state filled with gas. When the stamping upper die 8 is not inflated, the stamping upper die 8 is in a flat state and can be inserted into the inner cavity of the stamping bottom die 5 at will. When the airbag snap ring 9 is not inflated, the airbag snap ring 9 is also in a flat state. The airbag snap ring 9 can enter the card slot 52 after passing through the slot 51. After inflation, the airbag snap ring 9 is in an inflated state, and the outer wall of the inflated airbag snap ring 9 is closely attached to the inner wall of the card slot 52, so as to ensure that the outer sleeve 91 can protect the top of the stamping table 4.

[0027] As Figure 1 shown, guide columns 12 are fixed at the four corners of the top of the workbench 1. The top ends of the guide columns 12 are fixed with a fixed platform 13. The hydraulic cylinder 11 is fixed on the fixed platform 13. The telescopic end of the hydraulic cylinder 11 can penetrate through the fixed platform 13 and extend downward. Specifically, the guide columns 12 play a role in supporting and stabilizing the fixed platform 13, and during the sliding process of the stroke slider 10, the stroke slider 10 always slides along the guide columns 12 and will not displace.

[0028] As Figures 1 - 4 shown, a moving platform 3 is further provided at the bottom of the stamping table 4. A lifting mechanism 2 is provided on the moving platform 3. The lifting mechanism 2 includes a linear motor 22. A lifting base 21 is provided on the side wall of the slider of the linear motor 22. A push rod 23 is fixed on the top of the lifting base 21. The push rod 23 penetrates through the top of the moving platform 3 and extends upward into the stamping table 4. A bottom support plate 53 is provided at the bottom of the stamping bottom die 5. The top end of the push rod 23 is connected to the bottom support plate 53.

[0029] Specifically, the linear motor 22 drives the slider to move upward. The slider drives the lifting base 21 to move upward. The lifting base 21 drives the push rod 23. The push rod 23 pushes the bottom support plate 53 upward. The bottom support plate 53 moves upward and pushes the composite product located inside the stamping bottom die 5 upward, which is beneficial to the demoulding of the composite product.

[0030] As Figure 2As shown, a fixing frame 17 is further provided on the rear surface of the bottom die workbench 1, and a driving mechanism 16 is provided on one side of the fixing frame 17. The driving mechanism 16 is used to push or pull the moving table 3 to move;

[0031] Specifically, before pressing the composite material product, the driving mechanism 16 is used to push the moving table 3 forward and drive the stamping table 4 to move forward. The top of the stamping bottom die 5 is completely exposed and there is no obstruction above. At this time, the composite material product can be placed into the stamping bottom die 5. The driving mechanism 16 can use an oil cylinder as an actuator and an external oil pump as a driving part to provide power to the oil cylinder, so that the driving mechanism 16 can push or pull the moving table 3 and the stamping table 4.

[0032] As Figure 1 shown, a limiting block 14 is provided on the outer wall of the stroke slider 10, and a limiting column 7 is provided on the top of the bottom die workbench 1. The center lines of the limiting column 7 and the limiting block 14 are on the same straight line;

[0033] Specifically, during the process of the hydraulic cylinder 11 pushing the stroke slider 10 to move downward, the stroke slider 10 drives the limiting block 14 to move downward synchronously. After the bottom of the limiting block 14 contacts the top of the limiting column 7, the limiting block 14 and the stroke slider 10 cannot continue to move downward. At this time, the stroke slider 10 reaches the lowest position, and at this time, the stamping upper die 8 also enters the inner cavity of the stamping bottom die 5.

[0034] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
