Description

Technical Field

[0001] This invention relates to the technical field of hydraulic presses, and in particular to a high-speed hydraulic press. Background Technology

[0002] A hydraulic press is a machine that uses liquid as its working medium and is designed based on Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the press itself, a power system, and a hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. In the manufacturing process of metal parts, hydraulic presses are often used to control the disassembly and assembly of molds.

[0003] In the process of fully automated raw material forming in molds, the upper and lower molds are typically controlled by a hydraulic press. A robotic arm feeds the raw material, and a demolding mechanism separates the raw material from the upper mold. The robotic arm then removes the raw material. To facilitate the operation of the robotic arm, a larger gap is generally required between the upper and lower molds. However, traditional hydraulic presses use a single drive mechanism to combine and separate the molds, which makes the separation and combination of the upper and lower molds take longer and reduces the speed of fully automated raw material forming. This means that traditional hydraulic presses cannot adequately meet the requirements of fully automated raw material forming in molds. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a high-speed hydraulic press that can effectively meet the needs of fully automatic raw material forming and processing of molds.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A high-speed hydraulic press includes a top plate and a base. Four guide columns are fixedly installed at the four corners between the base and the top plate. A fixed beam and a movable plate are arranged sequentially from top to bottom between the base and the top plate. The four guide columns pass through the four corners of the fixed beam and the four corners of the movable plate and are slidably connected to the fixed beam and the movable plate. A main cylinder is fixedly installed at the center of the top plate. An upper mold is fixedly installed at the center of the bottom side of the movable plate by bolts. A lower mold is fixedly installed at the center of the top side of the base. The output end of the main cylinder is connected to the fixed beam through a connector. A forming mechanism is provided on the outer periphery of the lower mold. An acceleration component is provided between the fixed beam and the movable plate. A control component is provided on the bottom side of the fixed beam, and the control component controls the operation of the acceleration component.

[0007] In a preferred embodiment, the present invention may be further configured such that: the connecting member includes an adjusting locking nut, the adjusting locking nut is threaded onto the output end of the main cylinder, a nut pressure plate is rotatably sleeved on the outer periphery of the adjusting locking nut, and the nut pressure plate is fixedly connected to the fixed beam by a plurality of bolts, and the bottom end of the adjusting locking nut extends to the lower end of the fixed beam.

[0008] By adopting the above technical solution, the depth of the main cylinder output end within the adjusting locking nut is controlled by rotating the adjusting locking nut, thereby adjusting the height of the hollow part inside the locking nut, and thus controlling the depth of the acceleration rod inserted into the adjusting locking nut, thereby adjusting the minimum distance between the moving plate and the base, so that the device can be adjusted accordingly according to the robot arm.

[0009] In a preferred embodiment, the present invention may be further configured such that the forming mechanism includes three forming cylinders, the three forming cylinders are fixedly mounted on the outer periphery of the lower mold by bolts, and the output ends of the three forming cylinders are respectively fixedly mounted with a first punch, a second punch and a third punch.

[0010] By adopting the above technical solution, the forming cylinder, which is fixed to the outer periphery of the lower mold with bolts, is easier to disassemble and replace. After the forming cylinder is damaged, it can be restored to use simply by replacing the forming cylinder, thus reducing the operating cost of the device.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the acceleration assembly includes two acceleration cylinders; an acceleration rod is fixedly mounted at the center of the top side of the moving plate by bolts; the two acceleration cylinders are disposed opposite to each other on the outer periphery of the acceleration rod; an acceleration cylinder mounting plate is fixedly mounted at the bottom end of each acceleration cylinder; the acceleration cylinder mounting plate is fixedly connected to the moving plate by bolts; and an acceleration cylinder hook is fixedly mounted at the top end of each acceleration cylinder, and the acceleration cylinder hook is fixedly connected to the fixed beam by bolts.

[0012] By adopting the above technical solution, the acceleration cylinder is fixed to the moving plate and fixed beam by the accelerator hook, the acceleration cylinder mounting plate and bolts, so that the acceleration cylinder can be disassembled and replaced. After the acceleration cylinder is damaged, only the acceleration cylinder needs to be replaced to restore its use, which reduces the operating cost of the device.

[0013] In a preferred embodiment, the present invention can be further configured such that: two limiting rods are fixedly mounted on the top side of the moving plate, and the top of each limiting rod passes through the fixed beam and is slidably connected to the fixed beam; the limiting rod is in clearance fit with the acceleration moving rod and the acceleration cylinder.

[0014] By adopting the above technical solution, the movement between the moving plate and the fixed beam is limited and guided by the limiting rod, so as to prevent the use of the device from being affected by the excessive gap between the moving plate and the fixed beam due to the acceleration cylinder.

[0015] In a preferred embodiment, the present invention can be further configured as follows: the control component includes two cylinder supports; two pressure strips are fixedly mounted on the bottom side of the fixed beam by bolts, and the pressure strips are disposed opposite to each other on the outer periphery of the acceleration rod; two stops are slidably mounted between the two pressure strips; the two cylinder supports are fixedly mounted on the outer periphery of the fixed beam at positions corresponding to the two stops by bolts; a stop cylinder is provided between the stop and the corresponding cylinder support; the output end of the stop cylinder is fixedly connected to the corresponding stop; and the outer shell of the stop cylinder is fixedly connected to the corresponding cylinder support.

[0016] By adopting the above technical solution, the movement of the stop block is constrained and guided by two pressure bars, so that the stop block moves along a certain trajectory, making the movement of the stop block more stable.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] 1. When using the device, the preheated raw material is placed into the lower mold by the robotic arm. Then, the forming mechanism, acceleration component, control component, upper mold and lower mold work together to complete the forming operation of the raw material. The cooperation between the acceleration component and the control component enables the upper mold and lower mold to be quickly assembled and separated, shortening the assembly and disassembly time between the upper mold and lower mold, and does not affect the stable assembly between the upper mold and lower mold. Thus, this improved hydraulic press can well meet the requirements of fully automatic raw material forming processing.

[0019] 2. The forming cylinder, accelerating cylinder, and stopping cylinder are fixedly connected to the lower mold, moving plate, or fixed beam through a detachable structure, which allows the forming cylinder, accelerating cylinder, and stopping cylinder to be disassembled and replaced. If the forming cylinder, accelerating cylinder, and stopping cylinder are damaged, only the forming cylinder, accelerating cylinder, and stopping cylinder need to be replaced to restore the device to use, thus reducing the operating cost of the device.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1-3 The present invention discloses a high-speed hydraulic press, comprising a top plate 1 and a base 2. Four guide pillars 7 are fixedly installed at the four corners between the base 2 and the top plate 1. A fixed beam 8 and a movable plate 9 are arranged sequentially from top to bottom between the base 2 and the top plate 1. The four guide pillars 7 pass through the four corners of the fixed beam 8 and the four corners of the movable plate 9 and are slidably connected to the fixed beam 8 and the movable plate 9. A main cylinder 10 is fixedly installed at the center of the top plate 1. An upper mold 11 is fixedly installed at the center of the bottom side of the movable plate 9 by bolts. The upper mold 11 has a built-in demolding mechanism. A lower mold 12 is fixedly installed at the center of the top side of the base 2. The output end of the main cylinder 10 is connected to the fixed beam 8 through a connector 6. The connecting component 6 includes an adjusting locking nut 61, which is threaded onto the output end of the main cylinder 10. A nut pressure plate 62 is rotatably fitted onto the outer periphery of the adjusting locking nut 61, and the nut pressure plate 62 is fixedly connected to the fixed beam 8 by several bolts. The bottom end of the adjusting locking nut 61 extends to the lower end of the fixed beam 8, and the bottom end of the adjusting locking nut 61 and the bottom end of the fixed beam 8 are on the same plane. The adjusting locking nut 61 is hollow and is rotatably connected to the fixed beam 8. By rotating the adjusting locking nut 61, the depth of the output end of the main cylinder 10 within the adjusting locking nut 61 is controlled, thereby adjusting the height of the hollow part inside the locking nut 61. This, in turn, controls the depth to which the acceleration rod 41 is inserted into the adjusting locking nut 61, thereby adjusting the minimum distance between the moving plate 9 and the base 2.

[0027] A forming mechanism 3 is provided on the outer periphery of the lower mold 12. The forming mechanism 3 includes three forming cylinders 31, which are fixedly mounted on the outer periphery of the lower mold 12 by bolts. The output ends of the three forming cylinders 31 are inserted into the grooves of the lower mold 12 and respectively fixedly mounted with a first punch 32, a second punch 33, and a third punch 34. The first punch 32, the second punch 33, and the third punch 34 are slidably connected to the inner wall of the groove of the lower mold 12. The forming cylinders 31, which are fixed to the outer periphery of the lower mold 12 by bolts, make it easier to disassemble and replace them.

[0028] An acceleration assembly 4 is provided between the fixed beam 8 and the moving plate 9. The acceleration assembly 4 includes two acceleration cylinders 42. An acceleration rod 41 is fixedly mounted on the center position of the top side of the moving plate 9 by bolts. When the acceleration rod 41 is inserted into the adjusting locking nut 61, the acceleration rod 41 and the inner wall of the adjusting locking nut 61 are in clearance fit. The two acceleration cylinders 42 are arranged opposite to each other on the outer periphery of the acceleration rod 41. An acceleration cylinder mounting plate 43 is fixedly mounted on the bottom end of the acceleration cylinder 42. The outer shell of the acceleration cylinder 42 and the corresponding acceleration cylinder mounting plate 43 are integrally cast. The acceleration cylinder mounting plate 43 is bolted to the moving plate 9. The accelerator cylinder 42 is fixedly connected to a top end with an accelerator cylinder hook 44. The output end of the accelerator cylinder 42 and the corresponding accelerator cylinder hook 44 are integrally cast. The accelerator cylinder hook 44 is fixedly connected to the fixed beam 8 by bolts. Two limiting rods 45 are fixedly installed on the top side of the moving plate 9, and the top of each limiting rod 45 passes through the fixed beam 8 and is slidably connected to the fixed beam 8. The limiting rod 45 is clearance-fitted with the accelerator moving rod 41 and the accelerator cylinder 42. A nut is threaded onto the top of the limiting rod 45, and the nut is located on the top side of the fixed beam 8. The accelerator cylinder 42 is fixed to the moving plate 9 and the fixed beam 8 by the accelerator cylinder hook, the accelerator cylinder mounting plate 43, and the bolts, allowing the accelerator cylinder 42 to be disassembled and replaced. The limiting rods 45 constrain and guide the movement between the moving plate 9 and the fixed beam 8.

[0029] A control component 5 is provided on the bottom side of the fixed beam 8, and the control component 5 controls the operation of the acceleration component 4. The control component 5 includes two cylinder supports 53. The outer shell of the acceleration cylinder 42 is integrally cast with the corresponding cylinder support 53. Two pressure strips 51 are fixedly mounted on the bottom side of the fixed beam 8 by bolts, and the pressure strips 51 are positioned opposite each other on the outer periphery of the acceleration rod 41. Two stops 52 are slidably mounted between the two pressure strips 51. The two cylinder supports 53 are fixedly mounted on the outer periphery of the fixed beam 8 at the positions corresponding to the two stops 52 by bolts. A stop cylinder 54 is provided between the stop 52 and the corresponding cylinder support 53. The output end of the stop cylinder 54 is fixedly connected to the corresponding stop 52, and the outer shell of the stop cylinder 54 is fixedly connected to the corresponding cylinder support 53. The movement of the stop 52 is constrained and guided by the two pressure strips 51, so that the stop 52 moves along a certain trajectory.

[0030] The implementation principle of the above embodiment is as follows: When using the device, the preheated raw material is placed into the lower mold 12 by the robotic arm. Then, the moving plate 9 is rapidly lowered by the acceleration cylinder 42 until the nut on the limit rod 45 contacts the fixed beam 8 and the perforated plate stops moving downward. At this time, the moving plate 9 and the upper mold 11 are lowered to the appropriate position. Then, the stop block cylinder 54 pushes the stop block 52 to slide in the pressure strip 51. The two stop blocks 52 fit together to close the inner hole of the adjusting locking nut 61. At this time, the acceleration moving rod 41 and the stop block 52 are in contact. The contact surfaces are mutually resisted, and the distance between the limiting rod 45 and the fixed beam 8 and the moving plate 9 is kept stable. Then, the main cylinder 10 smoothly pushes the upper mold 11 downward, so that the upper mold 11 and the lower mold 12 are closed, completing the mold closing action of the upper and lower molds 12. Finally, the forming cylinder 31 runs to push the first punch 32, the second punch 33 and the third punch 34 to slide between the upper mold 11 and the lower mold 12. With the constraint and limitation of the upper mold 11 and the lower mold 12 on the raw material, the raw material is formed into the desired product.

[0031] After the product is stamped, the forming cylinder 31 activates the inner rod to retract, and the forming cylinder drives the first punch 32, the second punch 33, and the third punch 34 to slide back to their original positions, causing them to separate from the raw material. Due to the separation of the first punch 32, the second punch 33, and the third punch 34 from the raw material, the adhesion between the raw material and the lower die 12 decreases. Subsequently, the main cylinder 10 pulls the fixed beam 8 upward, while the stop cylinder 54 moves and pulls the stop block 52 to slide back to its original position along the pressure bar 51. The two stops 52 separate, and the stop block 52 accelerates the moving rod. Once the resistance between 41 is released, the acceleration cylinder 42 drives the moving plate 9 to move towards the fixed beam 8, reducing the distance between the moving plate 9 and the fixed beam 8. The top of the movable rod is inserted into the adjusting locking nut 61. At this time, the moving plate 9 drives the upper mold 11 to move and reset to the origin. The upper mold 11 and the lower mold 12 separate. Since the adhesion between the upper mold 11 and the forming material is greater than that between the lower mold 12 and the forming material, the forming material moves together with the upper mold 11. Then, the built-in demolding mechanism causes the stamped product to detach from the upper mold 11. Subsequently, the robotic arm picks up the product, thus completing the entire stamping cycle.

[0032] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
