Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic press technology, specifically to a hydraulic press for producing automotive parts molds to prevent workpiece loosening. Background Technology
[0002] Automotive parts molds refer to molds used in the automotive field to manufacture automotive parts. In the production process of automotive parts molds, hydraulic presses are used to transmit energy through liquid pressure to achieve mold processing and forming operations. However, automotive parts molds are prone to loosening or shaking when hydraulically pressed, which can easily affect subsequent polishing.
[0003] To address the aforementioned issues, a utility model patent with publication number CN213793837U discloses a hydraulic press for producing automotive sheet metal parts molds to prevent workpiece loosening. The press first places the mold on a mounting box and then a motor drives a first transmission chain to rotate. This first transmission chain drives a first gear, a second gear, and a screw to rotate, causing the mounting sleeve to move towards the center of the mounting box from the screw surface. The clamping plates on both sides of the press then clamp the mold to prevent loosening. While this method effectively prevents workpiece loosening, the deformation of the automotive parts mold under hydraulic pressure can easily impact the clamping plates and screw. Over time, this can cause deformation or even damage to the clamping plates and screw, affecting the clamping effect on the workpiece and resulting in loosening during hydraulic operation.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Please see Figures 1 to 4 A hydraulic press for producing automotive parts molds to prevent workpiece loosening includes a hydraulic press body 1, on which a hydraulic plate 2 and a hydraulic table 3 are mounted. The hydraulic table 3 has a groove with an anti-slip pad 20 inside, which allows the automotive parts mold to be placed stably on the hydraulic table 3 and reduces the impact of the hydraulic force generated during hydraulic operation on the hydraulic table 3. It also includes a fixing plate 4, a support plate 5, a drive assembly, a support column 6, a clamping plate 7, and a clamping assembly. Two fixing plates 4 are symmetrically and detachably connected to the top of the hydraulic table 3. Each fixing plate 4 is symmetrically connected to... Two fixing blocks 17 are connected, and fixing screws 18 are threadedly connected between the fixing blocks 17 and the hydraulic table 3 to facilitate the installation and removal of the fixing plates 4 on the hydraulic table 3. The support plates 5 are movably set on the upper side of each fixing plate 4 and rotatably set on the upper side of the hydraulic table 3. The drive assembly is installed on each fixing plate 4. There are two support columns 6, which are symmetrically connected to the top of each support plate 5. The clamping plates 7 are movably set on one side of each support column 6 and rotatably set on the upper side of the fixing plates 4. The clamping assembly is installed between each clamping plate 7 and the adjacent support column 6.
[0040] refer to Figure 1 as well as Figure 3The clamping assembly includes a first electric cylinder 8, a push block 9, a buffer rod 10, and a buffer plate 11. The first electric cylinder 8 is installed on one side of an adjacent support column 6, and the output end of the first electric cylinder 8 is connected through the support column 6. The push block 9 is fixedly connected to the output end of the first electric cylinder 8. The support column 6 has a push groove for the push block 9 to move. There are two buffer rods 10, and both buffer rods 10 can be detachably connected to one side of the clamping plate 7. The support column 6 has a buffer opening for the buffer rods 10 to move. The buffer plate 11 is fixedly connected to one side of each buffer rod 10. The buffer opening has a buffer groove for the buffer plate 11 to slide. There is a certain frictional resistance between the buffer rod 10 and the buffer opening, and between the buffer plate 11 and the buffer plate 11. The buffer rod 10 and the buffer plate 11 will not move arbitrarily in the buffer opening and the buffer groove, and a certain pushing force is required. Elastic pads 21 are fixedly connected to multiple clamping plates 7, which can reduce the impact of hydraulic shock on the clamping plate 7. At the same time, the elastic pads 21 will also deform to a certain extent to buffer when subjected to hydraulic shock.
[0041] When the first electric cylinder 8 is activated, it pushes the push block 9, causing it to move within the push groove and push the clamping plate 7, moving it to a suitable clamping position. This allows the two clamping plates 7 and the two elastic pads 21 to stably clamp automotive parts molds of different specifications. Simultaneously, the position of the automotive parts mold can be adjusted to be directly below the hydraulic plate 2. Then, the output end of the first electric cylinder 8 can drive the push block 9 back, away from the clamping plate 7. When the hydraulic plate 2 applies hydraulic pressure to the automotive parts mold, and the clamping plate 7 is subjected to impact, the buffer rod 10 and the buffer plate 11 will move within the buffer opening and buffer groove respectively, slightly adjusting the position of the clamping plate 7. This provides some buffering against the impact force, reducing the deformation of the clamping plate 7 caused by the impact.
[0042] refer to Figure 1 as well as Figure 4 The drive assembly includes a second electric cylinder 12, a drive cylinder 13, and a motor 14. The second electric cylinder 12 is mounted on the top of the fixed plate 4. The drive cylinder 13 is fixedly connected to the output end of the second electric cylinder 12. The motor 14 is mounted inside the drive cylinder 13, and the output end of the motor 14 is fixedly connected to the adjacent support plate 5. A drive block 19 is fixedly connected to the bottom end of the drive cylinder 13. A drive groove is provided on the fixed plate 4 for the drive block 19 to slide, so that the drive cylinder 13 can move stably on the fixed plate 4.
[0043] When the second electric cylinder 12 is started, the drive cylinder 13 can drive the motor 14 to move. At the same time, the support plate 5 can drive the support column 6 and the clamping plate 7 to move. The position of the clamping plate 7 can be adjusted so that the clamping plate 7 can clamp the automotive parts molds of different specifications. When the motor 14 is started, the support plate 5 will drive the two adjacent support columns 6 to rotate, so that the two clamping plates 7 can be rotated to the appropriate clamping positions respectively. The two clamping plates 7 can be used in sequence, which reduces the wear of the clamping plates 7 on the automotive parts molds and also reduces the deformation of the clamping plates 7.
[0044] refer to Figure 3 A connecting plate 15 is fixedly connected to one side of the buffer rod 10, and two connecting screws 16 are threadedly connected between the connecting plate 15 and the adjacent clamping plate 7.
[0045] By tightening the two connecting screws 16 between the connecting plate 15 and the clamping plate 7, the connecting plate 15 can be installed and removed from the clamping plate 7. This allows for the connection and removal of the buffer rod 10 and the clamping plate 7. The clamping plate 7 can be replaced according to its deformation and wear, reducing the impact of the deformation of the clamping plate 7 on the clamping effect.
[0046] In summary, the hydraulic press for producing automotive parts molds to prevent workpiece loosening first places the automotive parts mold on the hydraulic table 3, and simultaneously starts the two second electric cylinders 12, causing the two drive cylinders 13 to drive the two motors 14, two support plates 5, and multiple support columns 6 to move respectively. After the two opposing clamping plates 7 have moved to the appropriate clamping positions, the two opposing first electric cylinders 8 are simultaneously started, causing the two push blocks 9 to push the two adjacent clamping plates 7 respectively, so that the two clamping plates 7 and the two elastic pads 21 stably clamp the automotive parts mold. When the hydraulic plate 2 applies hydraulic pressure to the automotive parts mold, the push block 9 can move back into the push groove. At the same time, when the clamping plate 7 is subjected to impact force, the buffer rod 10 and the buffer plate 11 will move slightly a certain distance in the buffer opening and buffer groove respectively, thereby buffering the impact force on the clamping plate 7 and reducing the deformation of the clamping plate 7.
