Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, and in particular to a frame guide rail type hydraulic press. Background Technology

[0002] A hydraulic press is a type of mechanical equipment that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The pump forces the hydraulic oil through hydraulic lines into the cylinder. Several sets of interlocking seals in the cylinder prevent the hydraulic oil from leaking. Finally, a one-way valve allows the hydraulic oil to circulate in the tank, causing the cylinder to perform work and thus complete a certain mechanical action, thereby generating productivity.

[0003] A prior patent application with publication number CN211892099U discloses a frame-type guide rail hydraulic press, including a machine body, a hydraulic cylinder, a slider, and a worktable. The worktable is installed below the machine body, and the hydraulic cylinder is installed inside the upper part of the machine body. The slider is fixedly connected to the piston of the hydraulic cylinder, and the hydraulic cylinder drives the slider to slide up and down. Guide rails are installed longitudinally at the four corners of the machine body, and guide copper plates are installed on two surfaces at the four corners of the slider. The guide copper plates cooperate with the guide rails for guidance. When the hydraulic cylinder drives the slider to move up and down, the guide copper plates and guide rails guide the slider's up and down movement, thereby ensuring the slider's stable linear movement. At the same time, the gap between the guide rails and the guide copper plates can be adjusted according to production requirements to ensure consistent precision among the four guide rails, thereby ensuring the guiding accuracy of the equipment and avoiding damage to the equipment due to product asymmetry. Furthermore, the entire machine body has low deformation and high rigidity.

[0004] In the above scheme, the frame-type hydraulic press has a bulky and rough structure, and only the front and rear sides have space for operation to change molds and pick up and put down workpieces. It is not conducive to changing molds, and it is difficult to cooperate with the robot to achieve automated pressure processing. The guide is mostly guided by guide columns, which cannot achieve precision adjustment. The hydraulic station is located on the left and right sides of the equipment, which affects the usable space on the left and right sides and occupies a large area on the left and right sides.

[0035] The present invention will now be described in detail with reference to the accompanying drawings.

[0036] As shown in the figure, the frame guide rail type hydraulic press includes a machine body 1, a main oil cylinder 11, and a piston rod 12 that can be telescopically mounted on the drive end of the main oil cylinder 11. The main oil cylinder 11 is mounted on the upper side of the machine body 1. The piston rod 12 is equipped with a drive slider 13, and the drive slider 13 is connected to a sliding guide plate 14. Longitudinal guide rails 15 are respectively provided on both sides of the machine body 1, and the sliding guide plate 14 moves longitudinally along the longitudinal guide rails 15 on both sides. A fixed worktable 16 is provided on the lower side of the machine body 1. The fixed worktable 16 is equipped with a fixed mold 17 for positioning the workpiece. A hydraulic station 101 is provided on the rear side of the machine body 1. The hydraulic station 101 is equipped with an oil tank, an integrated valve, and a motor oil pump group 103. A power distribution box 102 is installed on the left side of the hydraulic station 101.

[0037] The hydraulic station 101 is located at the rear of the equipment, occupying little space on both sides, which greatly saves space for the hydraulic press user. The frame guide rail type body 1 design allows operation from all four sides of the body 1, positioning the fixed mold 17. The main unit is compactly designed and the layout of the main oil cylinder 11, hydraulic station 101, and power distribution box 102 is reasonable and easy to maintain.

[0038] The drive slider 13 has longitudinal sliding seats 18 installed at both ends, and the outer wall of the longitudinal sliding seat 18 is provided with an outer guide plate 19 that slides and engages with the longitudinal guide rail 15. Limiting seats that engage with the outer guide plate 19 are installed at the top and bottom of the longitudinal guide rail 15. In this embodiment, the drive slider 13, mounted on the piston rod 12 of the main cylinder 11, can move up and down under hydraulic pressure. A processing mold is installed at the bottom of the drive slider 13. The workpiece positioned by the fixed mold 17 is installed on the fixed worktable 16, and the processing mold processes the positioned workpiece. During processing, the drive slider 13 slides and engages with the longitudinal guide rail 15 through the outer guide plate 19 of the longitudinal sliding seat 18, ensuring that the processing mold is longitudinally aligned with the workpiece to be processed, enabling precise processing and improving processing efficiency.

[0039] Furthermore, a loading / unloading mechanism 2 for loading and unloading workpieces is provided on the front side of the machine body 1. The loading / unloading mechanism 2 includes a loading platform 4 for loading the workpieces to be processed onto the fixed worktable 16 and a unloading platform 3 for unloading the processed workpieces. The loading platform 4 and the unloading platform 3 are capable of lifting and lowering. The loading / unloading mechanism 2 can replace manual loading and unloading, which can not only improve the efficiency of loading and unloading but also reduce work errors. For some workpieces with larger areas, automated loading and unloading can be achieved by having the loading platform 4 and the unloading platform 3 work separately.

[0040] Compared to the traditional single platform, this solution adopts a combination of loading platform 4 and unloading platform 3. The workpiece is first taken out from the fixed mold 17 through the unloading platform 3. The loading platform 4 moves up and down and aligns with the fixed mold 17, so that new workpieces can be put into the fixed mold 17 for subsequent processing, saving time and further improving the efficiency of loading and unloading.

[0041] Specifically, the loading and unloading mechanism 2 also includes a loading frame 21, which is provided with a first longitudinal guide rod 22 and a second longitudinal guide rod 23 arranged longitudinally. The first longitudinal guide rod 22 and the second longitudinal guide rod 23 are arranged in parallel. The loading platform 4 is equipped with a first guide sleeve 24 that slides with the first longitudinal guide rod 22, and the unloading platform 3 is equipped with a second guide sleeve 25 that slides with the second longitudinal guide rod 23. The loading platform 4 is located on top of the unloading platform 3. The loading frame 21 is provided with a first lifting cylinder 26 and a second lifting cylinder 27 arranged longitudinally, wherein the driving end of the first lifting cylinder 26 is connected to the loading platform 4, and the driving end of the second lifting cylinder 27 is connected to the unloading platform 3. The lifting and lowering of the loading platform 4 and the unloading platform 3 are controlled and driven separately. Driven by the first lifting cylinder 26, the loading platform 4 slides through the first guide sleeve 24 and the first longitudinal guide rod 22 to ensure precise lifting and lowering to be flush with the fixed mold 17, so that the workpiece can smoothly transition from the loading platform 4 to the fixed mold 17. Similarly, driven by the second lifting cylinder 27, the loading platform 4 slides through the second guide sleeve 25 and the second longitudinal guide rod 23 to ensure precise lifting and lowering to be flush with the fixed mold 17, so that the workpiece can smoothly enter the unloading platform 3 from the fixed mold 17.

[0042] When the unloading platform 3 is blocked by the loading platform 4 when it is raised, the first lifting cylinder 26 can drive the loading platform 4 to rise, leaving a corresponding space for the unloading platform 3 to rise and be flush with the fixed mold 17.

[0043] Specifically, the unloading platform 3 is equipped with an unloading support plate 31 for sliding support of the workpiece. Unloading side guide plates 32 are respectively provided on both sides of the unloading support plate 31. The unloading support plate 31 is equipped with a bottom guide rail 33 for guiding the workpiece to slide. The bottom guide rail 33 has flared openings at both ends. A slider is formed at the bottom of the workpiece. When the workpiece moves along the unloading support plate 31, the slider is precisely in sliding cooperation with the bottom guide rail 33 of the unloading support plate 31 to ensure the stability of unloading and the workpiece can be unloaded to the predetermined position.

[0044] Furthermore, the unloading support plate 31 has a recessed unloading drive groove 34 arranged along its length. The unloading drive groove 34 is equipped with an unloading linear module 35. An unloading drive seat 36 is installed at the drive end of the unloading linear module 35. The unloading drive seat 36 is equipped with a pin 37 that can hook the workpiece in a lifting manner. The unloading linear module 35 drives the unloading drive seat 36 to move along the length of the unloading linear module 35, that is, along the length of the unloading support plate 31. When unloading the workpiece, the unloading platform 3 is raised to be flush with the fixed mold 17. Then the unloading drive seat 36 moves to below the workpiece, and the pin 37 of the unloading drive seat 36 rises and inserts into the hole of the workpiece. Then the unloading drive seat 36 retracts along the unloading linear module 35, driving the workpiece into the unloading support plate 31. At the same time, the slider at the bottom of the workpiece slides in cooperation with the bottom guide rail 33 of the unloading support plate 31, thereby stably realizing the unloading.

[0045] Furthermore, the height of the unloading drive seat 36 will not exceed that of the unloading support plate 31, ensuring that the workpiece slides and fits against the unloading support plate 31 when it enters the unloading support plate 31. An unloading lifting cylinder 38 is arranged inside the unloading drive seat 36, and the drive end of the unloading lifting cylinder 38 is connected to the pin 37. The lifting cylinder built into the unloading drive seat 36 can drive the pin 37 to move up and down, thereby connecting the workpiece and facilitating unloading.

[0046] Specifically, the loading platform 4 is equipped with a loading support plate 41 for sliding support of the workpiece. Loading side guide plates 42 are respectively provided on both sides of the loading support plate 41. A belt drive mechanism 43 is arranged along the length of the loading side guide plate 42. A push plate 44 is installed on one of the long sides of the belt drive mechanism 43. The push plate 44 can push the workpiece on the loading support plate 41 into the fixed worktable 16. When the workpiece is being processed, the product can be placed in the loading support plate 41. After the workpiece in the hydraulic press is processed and unloaded, the loading platform 4 is raised and lowered to be flush with the fixed mold 17. Then the belt drive mechanism 43 moves under the drive of the motor, and the push plate 44 located on the two loading side guide plates 42 can move to push the workpiece on the loading support plate 41 into the fixed mold 17. The cylinder clamp in the fixed mold 17 clamps and positions the workpiece.

[0047] It should be noted that the gap between the loading support plate 41 and the unloading support plate 31 and the fixed mold 17 will not affect the movement of the workpiece and will not cause the workpiece to fall. The gap is controllable and is to prevent the loading support plate 41 and the unloading support plate 31 from colliding with the fixed mold 17.

[0048] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0049] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
