Description

Technical Field

[0001] The utility model relates to the technical field of glass production equipment, in particular to a full-automatic servo hydraulic press. Background Art

[0002] At present, the common glass presses on the market generally use hydraulic drive and pneumatic drive for their stamping systems. Both drive methods have their own disadvantages. For example, pneumatic drive has unstable pressure due to the compressibility of gas medium, so it is usually only suitable for scenarios with low precision requirements. Hydraulic drive has better pressure stability than pneumatic drive, but conventional hydraulic drive uses a proportional method with an asynchronous motor to drive the oil cylinder, which makes it difficult to achieve high-precision pressure output, resulting in unstable terminal stamping speed, low processing accuracy, and defects such as complex oil circuit structure and high maintenance cost.

[0003] In addition, the molding mold of the conventional glass press is opened or closed by two relatively arranged tie rods. However, when the molding pressure is high, the clamping force provided by the tie rods is insufficient, which may cause burrs to form on the surface of the glassware, affecting the molding quality.

[0004] The technical problem to be solved by the utility model is: how to solve the problems of complex structure, low pressure precision control and insufficient clamping force in the existing glassware hydraulic molding equipment. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a fully automatic servo hydraulic press having the characteristics of simple and compact structure, high pressure control precision and good molding quality.

[0006] The technical solution adopted by the utility model is as follows: a fully automatic servo hydraulic press, comprising a frame, a forming mechanism and a mold opening mechanism respectively mounted on the frame; the frame comprises a base, a turntable rotatably connected to the base, and a stamping support frame mounted above the turntable; the forming mechanism comprises a plurality of molds spaced apart along the circumference of the turntable and a punch mounted on the stamping support frame, each mold comprising a first mold core and a second mold core arranged opposite to each other, the first mold core and the second mold core being hinged to the turntable; the mold opening mechanism comprises a first tie rod, a second tie rod, and a mold opening power member, one end of the first tie rod being hinged to the first mold core, and the other end being connected to the mold opening power member, one end of the second tie rod being hinged to the second mold core, and the other end being connected to the mold opening power member, and further comprising a hydraulic mechanism and a mold locking mechanism;

[0007] The hydraulic mechanism includes a hydraulic cylinder mounted on a punch support frame, an oil pump connected to the hydraulic cylinder, and a servo motor driving the oil pump. The hydraulic cylinder drives the punch to move closer to or away from the die.

[0008] The mold locking mechanism includes a clamp and a mold locking power piece. The clamp is arranged on the edge of the turntable and below the punch. The mold locking power piece drives the clamp to clamp or release the first mold core and the second mold core.

[0009] The fully automatic servo hydraulic press of the present application drives an oil pump through a servo motor to supply oil to the hydraulic cylinder of the punch. The servo motor can achieve a constant output torque through a feedback system, so that the hydraulic cylinder can maintain a high-precision output pressure, thereby improving the molding accuracy of glassware. It is also more energy-efficient and saves high-end precision valves and other components, thereby simplifying the structure of the oil circuit, reducing the failure rate and reducing maintenance costs. In addition, by arranging a clamping mechanism at the stamping station, during stamping and forming, the clamping power component drives the clamp to clamp the mold, which can increase the clamping force and prevent burrs from forming on the surface of the glassware, thereby improving the molding quality.

[0010] In some embodiments, the clamping mechanism further includes a clamping seat, on which the clamp and the clamping power piece are mounted, the clamp including two oppositely arranged clamping blocks, the two clamping blocks being hinged to the clamping seat, and the clamping power piece being transmission-connected to the two clamping blocks.

[0011] By adopting the above technical solution, the two clamping blocks can be prevented from shifting by providing a clamping seat, thereby improving the clamping accuracy of the clamping mechanism.

[0012] In some embodiments, the mold locking mechanism further comprises a mold locking slider slidably connected to the clamping seat, one end of the mold locking slider is transmission-connected to the mold locking power member, and the other end is hinged to the two clamping blocks.

[0013] By adopting the above technical solution, by setting a locking slider that is slidably connected to the clamping seat, it is possible to facilitate the later maintenance and replacement of the locking power parts, and the sliding path of the locking slider can be limited by setting a guide device to improve the accuracy of the clamp in clamping the mold.

[0014] In some embodiments, the clamping mechanism further includes a first transmission block, a second transmission block, and a third transmission block, each of which is hinged to the clamping seat, and each clamping block corresponds to a first transmission block, a second transmission block, and a third transmission block, respectively. One end of the first transmission block is hinged to the clamping slider, and the other end is hinged to the second transmission block. The other end of the second transmission block is hinged to the clamping block. One end of the third transmission block is hinged to the clamping seat, and the other end is hinged to the first transmission block and the second transmission block.

[0015] By adopting the above technical solution, by providing the first transmission block, the second transmission block and the third transmission block, multi-stage joint transmission can be achieved, thereby improving the reliability of mold locking.

[0016] In some embodiments, a plurality of lower mold bases corresponding to the molds are arranged at intervals along the circumference of the turntable, the first mold core and the second mold core are hinged to the lower mold base, and a push rod is provided on the lower mold base.

[0017] By adopting the above technical solution, by setting up the lower mold base, the mold can be easily installed, and the ejector rod can lift the formed glassware from the lower mold base to prevent the glassware from sticking to the lower mold base and affecting the demolding of the glassware.

[0018] In some embodiments, the mold opening mechanism also includes a mold opening turntable, which rotates with the turntable. Each mold corresponds to a group of first pull rods and second pull rods. Each group of first pull rods and second pull rods is hinged with a connecting rod at one end away from the mold. The mold opening turntable is provided with a sliding groove that slides with the connecting rod, and the sliding groove is opened along the radial direction of the mold opening turntable.

[0019] By adopting the above technical solution, the driving connecting rod is moved closer to or farther away from the axis of the mold rotating seat, thereby driving the first pull rod and the second pull rod to open or close the first mold core and the second mold core, thereby realizing the opening and closing of the mold.

[0020] In some embodiments, the mold opening mechanism further includes a mold opening fixed seat covering the mold opening rotating seat, the mold opening fixed seat is stationary relative to the mold opening rotating seat, a guide groove is provided on the mold opening fixed seat, and a roller corresponding to the guide groove is provided on the connecting rod.

[0021] By adopting the above technical solution, a guide groove is provided on the mold opening fixed seat which is covered on the mold opening rotating seat. The roller on the connecting rod rolls in the guide groove, driving the connecting rod to slide in the slide groove, thereby realizing the opening and closing of the mold.

[0023] By adopting the above technical solution, when the roller rolls in the mold closing section, the connecting rod is stationary relative to the slide groove, so that the mold remains in the closed state. When the roller moves to the mold opening section, since the width of the mold opening section is greater than the diameter of the roller, under the push of the mold opening power part, the connecting rod slides toward the axis of the mold opening turntable, driving the mold to open. By setting the mold opening power part at the mold opening station, it can be ensured that the mold is opened at the mold opening station, so that the molded glassware can be taken out at the preset position.

[0024] In some embodiments, an air cooling mechanism is further included, which includes an air hood mounted above the turntable and a plurality of air blowing nozzles connected to the air hood, wherein the air blowing nozzles are arranged on the side and / or top of the mold.

[0025] By adopting the above technical solution and providing an air cooling mechanism, the cooling and solidification of the formed glassware can be accelerated, so that the formed glassware can be easily removed from the mold.

[0026] In some embodiments, the hydraulic mechanism further includes a hydraulic station, the servo motor and the oil pump are installed on the hydraulic station, and an oil tank is provided inside the hydraulic station.

[0027] By adopting the above technical solution and equipping a hydraulic station, stable hydraulic oil can be provided to the hydraulic press, which is conducive to the smooth operation of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The hydraulic cylinder 41 drives the punch to move closer to or away from the mold 21; the clamping mechanism 50 includes a clamp and a clamping power part 52. The clamp is arranged on the edge of the turntable 12 and is located below the punch. The clamping power part 52 drives the clamp to clamp or release the first mold core 211 and the second mold core 212.

[0040] The fully automatic servo hydraulic press 100 of the present application drives the oil pump 42 through the servo motor 43 to supply oil to the hydraulic cylinder 41 of the punch. The servo motor 43 can achieve a constant output torque through the feedback system, so that the hydraulic cylinder 41 can maintain a high-precision output pressure, thereby improving the molding accuracy of the glassware. It is also more energy-efficient and saves high-end precision valves and other components, thereby simplifying the structure of the oil circuit, reducing the failure rate and reducing maintenance costs. In addition, by arranging a clamping mechanism 50 at the stamping station, during stamping and forming, the clamping power part 52 drives the clamp to clamp the mold 21, which can increase the clamping force and prevent burrs from forming on the surface of the glassware, thereby improving the molding quality.

[0041] It should be noted that the number of punches corresponds to the number of the clamping mechanisms 50 , and the number of punches can be increased or decreased according to actual needs.

[0042] Optionally, each mold 21 may correspond to a first pull rod 31 and a second pull rod 32 respectively. In this case, the first pull rod 31 and the second pull rod 32 should rotate with the mold 21; or multiple molds 21 may correspond to a first pull rod 31 and a second pull rod 32, and the first pull rod 31 and the second pull rod 32 are set at the mold opening station. When the mold 21 arrives at the mold opening station, the first pull rod 31 and the second pull rod 32 are connected to the mold 21 and drive the mold 21 to open the mold.

[0043] like Figures 3 to 5 As shown, the mold clamping mechanism 50 further includes a clamping base 53, on which the clamp and the mold clamping power member 52 are mounted. The clamp includes two opposing clamping blocks 51, which are hingedly connected to the clamping base 53. The mold clamping power member 52 is in transmission connection with the two clamping blocks 51. The provision of the clamping base 53 prevents the two clamping blocks 51 from shifting, thereby improving the mold clamping accuracy of the mold clamping mechanism 50.

[0044] Optionally, in order to facilitate the clamping of the mold 21, a locking module is protruded on the side of the first mold core 211 and the second mold core 212 close to the clamp, and the locking module corresponds to the clamp mouth; when the clamp size is large, the clamp can also be directly clamped on the outer surface of the mold 21.

[0045] Preferably, in order to facilitate adjustment of the position of the clamping seat 53 , an elongated hole for the bolt to pass through is provided on the clamping seat 53 , so that the position of the clamping seat 53 can be adjusted within the length range of the elongated hole.

[0046] Furthermore, the mold clamping mechanism 50 includes a mold clamping slider 54 slidably connected to the clamping base 53. One end of the mold clamping slider 54 is in driving connection with the mold clamping power element 52, and the other end is hingedly connected to the two clamping blocks 51. The provision of the mold clamping slider 54 slidably connected to the clamping base 53 facilitates later maintenance and replacement of the mold clamping power element 52. Furthermore, a guide device can be provided to limit the sliding path of the mold clamping slider 54, thereby improving the precision with which the clamps grip the mold 21.

[0047] Optionally, the guide device can be a guide rod and a sliding sleeve, the guide sleeve is fixed on the clamping seat 53, the guide rod is fixed on the locking slider 54, and the guide sleeve and the guide rod are slidingly arranged; the guide device can also be a slider and a limiting groove, the slider is installed on the locking slider 54, the limiting groove is opened on the clamping seat 53, and the slider slides and fits in the limiting groove.

[0048] Furthermore, the mold clamping mechanism 50 also includes a first transmission block 55, a second transmission block 56, and a third transmission block 57, each of which is hinged to the clamping seat 53. Each clamping block 51 corresponds to a first transmission block 55, a second transmission block 56, and a third transmission block 57. One end of the first transmission block 55 is hinged to the mold clamping slider 54, and the other end is hinged to the second transmission block 56. The other end of the second transmission block 56 is hinged to the clamping block 51. One end of the third transmission block 57 is hinged to the clamping seat 53, and the other end is hinged to the first transmission block 55 and the second transmission block 56. By providing the first transmission block 55, the second transmission block 56, and the third transmission block 57, multi-stage articulated transmission can be achieved, thereby improving the reliability of mold clamping.

[0049] In one embodiment, to facilitate installation of the mold 21, a plurality of lower mold bases 22 corresponding to the mold 21 are circumferentially spaced apart on the turntable 12. A first mold core 211 and a second mold core 212 are hingedly connected to the lower mold base 22, and a push rod 23 is provided on the lower mold base 22. The lower mold base 22 facilitates installation of the mold 21. The push rod 23 lifts the formed glassware from the lower mold base 22, preventing it from sticking to the lower mold base 22 and hindering demolding. Accordingly, an air cylinder or oil cylinder corresponding to the push rod 23 can be provided at the bottom of the turntable 12 to drive the push rod 23 upward.

[0050] like Figure 3 and Figure 6 As shown, the mold opening mechanism 30 also includes a mold opening rotary seat 34, which rotates with the turntable 12. Each mold 21 corresponds to a set of first tie rods 31 and second tie rods 32. The end of each set of first tie rods 31 and second tie rods 32 away from the mold 21 is hinged with a connecting rod 35. The mold opening rotary seat 34 is provided with a slide groove 341 that slidably cooperates with the connecting rod 35. The slide groove 341 is opened along the radial direction of the mold opening rotary seat 34. By driving the connecting rod 35 close to or away from the axis of the mold rotating seat 34, the first tie rod 31 and the second tie rod 32 are driven to open or close the first mold core 211 and the second mold core 212, thereby realizing the opening and closing of the mold 21.

[0051] In this embodiment, the mold opening mechanism 30 further includes a mold opening fixed base 36 covering the mold opening rotating base 34. The mold opening fixed base 36 is stationary relative to the mold opening rotating base 34. The mold opening fixed base 36 is provided with a guide groove 361, and the connecting rod 35 is provided with a roller 37 corresponding to the guide groove 361. By providing the guide groove 361 on the mold opening fixed base 36 covering the mold opening rotating base 34, the roller 37 on the connecting rod 35 rolls in the guide groove 361, driving the connecting rod 35 to slide in the slide groove 341, thereby achieving the opening and closing of the mold 21.

[0052] Optionally, in order to achieve automatic mold opening, the distance between the center line of the guide groove 361 and the edge of the mold opening swivel seat 34 can be set to be variable, that is, when the mold 21 is in the mold closing state, the center line of the guide groove 361 is close to the edge of the mold opening swivel seat 34, so that the first pull rod 31 and the second pull rod 32 are in a clamped state; when the mold 21 is in the mold opening state, the center line of the guide groove 361 is far away from the edge of the mold swivel seat 34, so that the first pull rod 31 and the second pull rod 32 are in an open state.

[0053] In one embodiment, the guide groove 361 includes a mold-closing section and a mold-opening section 363. The sidewall of the mold-closing section rolls with the roller 37. The mold-opening section 363 is located at the mold-opening station. The width of the mold-opening section 363 is greater than the diameter of the roller 37. The mold-opening actuator 33 is mounted on the mold-opening base 36 and located at the mold-opening station, and is used to drive the connecting rod 35 to slide toward the interior of the mold-opening swivel base 34. When the roller 37 rolls in the mold-closing section, the connecting rod 35 remains stationary relative to the chute 341, maintaining the mold 21 in the closed state. When the roller 37 moves to the mold-opening section 363, because the width of the mold-opening section 363 is greater than the diameter of the roller 37, the connecting rod 35 slides toward the axis of the mold-opening swivel base 34 under the force of the mold-opening actuator 33, driving the mold 21 to open. By locating the mold-opening actuator 33 at the mold-opening station, the mold 21 can be opened at the mold-opening station, allowing the molded glassware to be removed from the predetermined position. In this embodiment, the mold opening power member 33 is a cylinder. In other embodiments, a spring can also be used as the mold opening power member 33, and the elastic force or tension of the spring can be used to realize the sliding of the connecting rod 35 in the sliding groove 341.

[0054] In one embodiment, the fully automatic servo-hydraulic press 100 of the present application further includes an air cooling mechanism 60. The air cooling mechanism 60 includes an air hood 61 mounted above the turntable 12 and a plurality of air blowing nozzles 62 connected to the air hood 61. The air blowing nozzles 62 are disposed on the side and / or top of the mold 21. The air cooling mechanism 60 can accelerate the cooling and solidification of the formed glassware, thereby facilitating removal of the formed glassware from the mold 21.

[0055] Optionally, the hydraulic mechanism 40 further includes a hydraulic station 44, on which the servo motor 43 and the oil pump 42 are mounted, and an oil tank is provided inside the hydraulic station 44. By equipping the hydraulic station 44, a stable supply of hydraulic oil can be provided to the hydraulic press, which is conducive to the smooth operation of the equipment.

[0056] The fully automatic servo hydraulic press 100 of the present application further includes a controller (not shown), which is used to control the coordinated operation of various mechanisms.
