Description

Technical Field

[0001] The present application relates to the technical field of stamping equipment, and in particular to a stamping mechanism for manufacturing lightweight glassware. Background Art

[0002] At present, the main processes for processing lightweight glassware include blowing, pressing, and stamping. Among them, blowing is the most traditional and is widely used in small and medium-sized glassware processing companies. However, there are natural defects in the blowing process, that is, during the blowing process, the wall thickness of the glassware is difficult to effectively control, and is greatly affected by the amount of feed, the air flow, and the air pressure. In the stamping process, with the cooperation of the mold and the punch head, not only the wall thickness of the glassware can be controlled, but also the stamping force and speed can be controlled, making the quality of the stamped glassware relatively stable, which is suitable for the manufacture of high-specification and high-requirement glassware.

[0003] However, at present, the stamping mechanisms of domestic glassware forming machines are mainly cylinder stamping, hydraulic cylinder stamping, screw nut mechanism or crank rocker mechanism. The durability of this type of stamping and forming device is poor, and the accuracy of the overlapping stamping mechanism decreases after working for a long time; and, since the glass furnace cellar of the glass factory needs to operate 24 hours a day to avoid the furnace cellar itself being scrapped, once these stamping mechanisms frequently malfunction and need maintenance, it will greatly affect the normal production of the glass factory and bring great economic losses.

[0004] Moreover, in the current glassware stamping process, the stamping processing line is single, and after the stamping is completed, it is necessary to maintain the pressure for a certain period of time to make the temperature of the glassware in the wall thickness direction after stamping tend to be consistent, so as to ensure the production quality of the glassware; even if a multi-station stamping mechanism is set up on the production line, due to the inconsistent working procedures and different stamping actions of each stamping station, the workload requirements of the stamping mechanism and the power setting requirements of the overall driving structure are relatively large, and it is difficult to ensure that the multi-station stamping mechanism can maintain continuous and stable operation. As a result, it is difficult to significantly improve the processing efficiency of glassware produced by the stamping process. Summary of the invention

[0005] In order to improve the problem that the processing efficiency of glassware produced by a stamping process is difficult to be significantly improved, the present application provides a stamping mechanism for manufacturing lightweight glassware.

[0008] The machine platform is provided with a control console located above the turntable, and a mold lifting area, a mold pressing area and a pressure holding area are sequentially provided on a side of the control console close to the turntable, the mold lifting area, the mold pressing area and the pressure holding area are connected to form a complete annular area corresponding to the plurality of sliding sleeves on the turntable, the mold lifting area corresponds to at least two of the sliding sleeves, and the mold pressing area corresponds to at least two of the sliding sleeves;

[0009] The mold lifting area, the die pressing area and the pressure holding area are each provided with electromagnets in a number not less than the number of the corresponding multiple sleeves. When the electromagnets in the mold lifting area are energized, their magnetic properties are different from those of the permanent magnets. When the electromagnets in the die pressing area and the pressure holding area are energized, their magnetic properties are the same as those of the permanent magnets.

[0010] Furthermore, after the multiple electromagnets in the die-stamping area are energized, the magnetism gradually increases along the rotation direction of the turntable, and the magnetic field intensity in the die-stamping area along the rotation track of the turntable increases linearly.

[0011] Furthermore, after the multiple electromagnets in the pressure-maintaining area are energized, their magnetism first remains the same along the rotation direction of the turntable and then gradually decreases.

[0012] Furthermore, the distance between two adjacent electromagnets in the die pressing area and the pressure holding area is smaller than the distance between two adjacent sliding sleeves on the turntable.

[0013] Furthermore, a slider is slidably arranged in the sleeve, the punch head is installed on the lower end surface of the slider, a buffer block is slidably arranged in the slider, the permanent magnet is installed on the buffer block, and a buffer component is arranged between the buffer block and the slider for achieving a delayed response to the downward movement of the buffer block and an immediate response to the upward movement of the buffer block.

[0014] Furthermore, the buffer assembly includes a connecting rod for connecting the buffer block and the permanent magnet, a sliding cavity is opened in the sliding slider, the buffer block is slidably arranged in the sliding cavity, one end of the connecting rod is sealed and slidable through the sliding slider and extends into the sliding cavity and is fixedly connected to the buffer block, and the sliding cavity is filled with a flowing medium.

[0015] Furthermore, the buffer block is provided with a plurality of reflux holes, the buffer block is provided with a one-way valve in the reflux hole for allowing only the flow medium to flow from top to bottom, the middle part of the buffer block is provided with a slow flow hole extending into the connecting rod, and the connecting rod is provided with a plurality of diversion holes connected to the slow flow hole on the peripheral side near one end of the buffer block.

[0016] Furthermore, when the buffer block moves upward to contact the upper cavity wall of the sliding cavity, there is a gap between the permanent magnet and the adjacent electromagnet on the console.

[0017] In summary, the beneficial technical effects of this application are:

[0018] 1. By sequentially arranging the die lifting area, die pressing area and pressure holding area on the control console, and arranging corresponding electromagnets in each area, and arranging a permanent magnet on the punch head, the pressing effect of the punch head in the die pressing area and the pressure holding area, and the lifting effect of the punch head in the die lifting area can be achieved, so that the punching mechanism of the present application can perform the punching manufacturing of multiple glassware at the same time, while ensuring the processing quality, greatly improving the punching processing efficiency of lightweight glassware; and the movement of the punch head is achieved by the magnetic repulsion or magnetic attraction between the permanent magnet and the electromagnet, which has a fast response speed, no mechanical wear, and convenient maintenance and repair. Under the premise of the rotating disk working, it is not necessary to set a complex transmission structure, which can ensure the long-term and stable operation of the punching mechanism;

[0019] 2. By adjusting the current on two adjacent electromagnets and the distance between the two adjacent electromagnets, the magnetic field continuity in the die lifting area, die pressing area and pressure holding area can be improved, and the punch head can be kept in a certain processing state during the rotation of the turntable to switch the workstation; especially in the die pressing area, the magnetic field strength along the rotating track of the turntable in the die pressing area increases linearly, so that the punching pressure on the glass paste can be gradually increased when the punch head moves in the die pressing area, and is not limited to a specific stamping workstation, and can achieve multiple pressure gradients and smooth pressurization effects, and can also prolong the time for the glass paste to be stamped, so as to ensure the stamping processing quality of the glassware as much as possible;

[0020] 3. By arranging a buffer block and a flowing medium in the slider, after the permanent magnet is subjected to the magnetic repulsion force, the buffer block can form a buffer downward movement between the slider, which can reduce the punching speed of the punch head, that is, realize the buffering effect when the punch head punches the glass paste, and ensure the punching quality. When the flowing medium in the lower part of the slide cavity completely enters the upper part of the slide cavity, the buffer block directly pushes the slider to drive the punch head to move downward, which can be well matched with the setting of gradually increasing the magnetic field strength in the die area to ensure high-quality stamping processing of glassware.

[0026] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0027] The present application embodiment discloses a punching mechanism for manufacturing lightweight glassware. Figure 1 , Figure 2 and Figure 3 , which includes a machine table 1 and a turntable 2 which is arranged on the machine table 1 and rotates step by step. Specifically, a plurality of lower molds 8 are installed in an evenly spaced circular array on the machine table 1, and each lower mold 8 corresponds to a work station. The turntable 2 is installed above the lower mold 8 at intervals, and the plurality of lower molds 8 rotate synchronously with the turntable 2. The space between the turntable 2 and the lower mold 8 can be used for the movement of the glass paste feeding tube and the material taking mechanical arm. The machine table 1 is provided with a stepping motor for driving the turntable 2 to rotate step by step. A plurality of stamping modules corresponding to the plurality of lower molds 8 are arranged on the turntable 2 at equal intervals. The stamping module includes a sleeve 3 fixed to the turntable 2 and a stamping head 41 which is slidably arranged in the sleeve 3. A through hole 21 is provided on the turntable 2 for the sleeve 3 to pass through, and a permanent magnet 42 is installed on the stamping head 41.

[0028] In addition, the machine 1 is provided with a control console 5 located above the turntable 2. The control console 5 is ring-shaped as a whole. A mold lifting area 51, a mold pressing area 52 and a pressure holding area 53 are sequentially arranged on the side of the control console 5 close to the turntable 2. The mold lifting area 51, the mold pressing area 52 and the pressure holding area 53 are connected to form a complete annular area corresponding to multiple sleeves 3 on the turntable 2. The mold lifting area 51 corresponds to at least two sleeves 3 on the turntable 2, and the mold pressing area 52 corresponds to at least two sleeves 3 on the turntable 2. In the specific setting, the mold lifting area 51 corresponds to three sleeves 3 on the turntable 2, and the mold pressing area 52 corresponds to two sleeves 3 on the turntable 2.

[0029] In addition, the mold lifting area 51, the die pressing area 52 and the pressure holding area 53 are each provided with an electromagnet 43 whose number is not less than the number of the corresponding multiple sleeves 3. When the electromagnet 43 in the mold lifting area 51 is energized, its magnetic properties are different from those of the permanent magnet 42, and when the electromagnet 43 in the die pressing area 52 and the pressure holding area 53 is energized, its magnetic properties are the same as those of the permanent magnet 42.

[0030] After being set up in this way, when the stamping mechanism of the present application is working, the glass paste feeding tube conveys the molten hot glass paste to one of the lower molds 8 corresponding to the mold lifting area 51, and the stepper motor drives the turntable 2 to rotate to convey the lower mold 8 to the die pressing area 52. The electromagnet 43 in the die pressing area 52 generates a magnetic field with the same magnetic property as the permanent magnet 42, thereby generating a repulsive force on the permanent magnet 42, so that the permanent magnet 42 can push the punch head 41 to move downward quickly in the sliding sleeve 3, and punch the glass paste in the lower mold 8 below. By controlling the magnetic field strength generated by the electromagnet in the die pressing area 52, the impact force of the punch head 41 can be adjusted, the stamping processing quality of the glassware can be accurately controlled, and when replacing glassware of different thicknesses or producing glassware with different stamping requirements, it is easier to adjust the impact force of the punch head 41.

[0031] Furthermore, by arranging the electromagnets 43 in the die area 52 in a number greater than the number of the stamping modules, the magnetic field to which the permanent magnets 42 are subjected when passing through the die area 52 can be as stable as possible without interruptions, thereby ensuring the stamping stability of the stamping head 41. When the turntable 2 continues to rotate until the lower mold 8 is transported to the pressure holding area 53, the magnetic repulsion force generated by the multiple electromagnets 43 in the pressure holding area 53 also pushes the stamping head 41 to maintain a certain downward pressure, thereby ensuring the continuous production of the stamping mechanism and maintaining the pressure and cooling the glassware after stamping, thereby effectively ensuring the processing quality of the glassware.

[0032] After the pressure holding is completed, the turntable 2 continues to rotate until the lower mold 8 is transported to the mold lifting area 51. At this time, the electromagnet 43 in the mold lifting area 51 generates a magnetic attraction force on the permanent magnet 42, so that the permanent magnet 42 drives the punch head 41 to lift up. In view of the fact that the mold lifting area 51 corresponds to three stamping modules in this embodiment, when the turntable 2 rotates to the first station where the lower mold 8 just enters the mold lifting area 51, the permanent magnet 42 drives the punch head 41 to lift up, and the glassware after the pressure holding is loosened in the lower mold 8; then, the turntable 2 rotates to the second station where the lower mold 8 enters the mold lifting area 51, and the material taking robot arm takes out the finished glassware on the lower mold 8, so that the complete stamping process of a glassware can be completed after the turntable 2 rotates one circle; then, the turntable 2 rotates to the third station where the lower mold 8 enters the mold lifting area 51, and the glass paste feeding tube continues to put new molten glass paste into the lower mold 8 to start the manufacture of another glassware.

[0033] By analogy, when N stamping modules are provided on the turntable 2, when operating at full speed, the stamping mechanism of the present application can simultaneously perform stamping and manufacturing of N glassware, greatly improving the processing efficiency of stamped glassware; if the factory has a small number of orders but cannot shut down, it is only necessary to control the working frequency of the glass paste feeding tube and the material taking robot arm. Therefore, the stamping mechanism of the present application can also flexibly switch between different production speeds without adding or reducing the overall components or molds, and there is no no-load damage to the moving parts of the stamping mechanism.

[0034] Specifically, in order to ensure the stability of the punch head 41 when it is running in each area on the turntable 2, on the one hand, after the multiple electromagnets 43 in the die area 52 are energized, the magnetism gradually increases along the rotation direction of the turntable 2, and the magnetic field strength along the rotation track of the turntable 2 in the die area 52 increases linearly, specifically by adjusting the current on the two adjacent electromagnets 43 and adjusting the distance between the two adjacent electromagnets 43, so as to form a superposition area of ​​the outermost magnetic field of the two adjacent electromagnets 43 to perform a magnetic field transition. In this way, the punch head 41 can gradually increase the punching pressure on the glass paste when it moves in the die area 52, and it is not limited to a specific punching station. During the entire process of the punch head 41 rotating with the turntable 2 in the die area 52, it can always maintain the punching effect under the action of the permanent magnet 42 and the electromagnets 43 in the die area 52, so that the time for the glass paste to be punched can be extended to ensure the punching processing quality of the glassware as much as possible.

[0035] On the other hand, after the multiple electromagnets 43 in the holding zone 53 are energized, the magnetism along the rotation direction of the turntable 2 first remains the same and then gradually decreases. Correspondingly, it is also necessary to control the current passed through two adjacent electromagnets in the holding zone 53 and the distance between two adjacent electromagnets 43, so that the magnetic field strength in the holding zone 53 can also be smoothly transitioned; on the other hand, the distance between two adjacent electromagnets 43 in the die pressing zone 52 and the holding zone 53 is smaller than the distance between two adjacent sleeves 3 on the turntable 2, so as to meet the above-mentioned requirement of smooth transition of magnetic field strength. Correspondingly, the distance between two adjacent electromagnets 43 in the die lifting zone 51 is also smaller than the distance between two adjacent sleeves 3 on the turntable 2, so as to prevent the magnetic attraction of the electromagnet 43 on the permanent magnet 42 from weakening when the stamping module is transferred between two adjacent stations in the die lifting zone 51, thereby causing the stamping head 41 to fall and smash the finished glassware.

[0036] In addition, although the magnetostrictive stamping method of the electromagnet 43 and the permanent magnet 42 has a fast response speed, no mechanical wear, and easy maintenance and repair, the disadvantage brought about by the fast response speed is that the stamping speed of the punch head 41 is relatively fast. Although the die pressing area 52 and the pressure holding area 53 with continuous magnetic fields can ensure the molding quality of the glassware, the high initial velocity of the punch head 41 will still cause a certain amount of internal stress to be stored in the glass paste, which is difficult to release quickly and may affect the subsequent molding quality of the glassware.

[0037] For this purpose, refer to Figure 3 and Figure 4 A slider 6 is also slidably arranged in the sleeve 3, a punch head 41 is installed on the lower end surface of the slider 6, a buffer block 7 is slidably arranged in the slider 6, a permanent magnet 42 is installed on the buffer block 7, and a buffer component is arranged between the buffer block 7 and the slider 6 for achieving a delayed response to the downward movement of the buffer block 7 and an immediate response to the upward movement of the buffer block 7.

[0038] Among them, the buffer assembly includes a connecting rod 71 for connecting the buffer block 7 and the permanent magnet 42, a closed sliding cavity 61 is opened in the slider 6, the buffer block 7 is slidably set in the sliding cavity 61, one end of the connecting rod 71 seals and slides through the slider 6 and extends into the sliding cavity 61 and is fixedly connected to the middle part of the buffer block 7, and the sliding cavity 61 is filled with a flowing medium, which can be a compressible gas medium, such as air, inert gas, etc., or an incompressible liquid medium, such as hydraulic oil, water, etc. In this embodiment, the flowing medium is selected as hydraulic oil with good thermal conductivity.

[0039] And refer to Figure 3 and Figure 4A plurality of reflux holes 72 are formed through the buffer block 7, a one-way valve 73 is provided in the reflux hole for allowing only the flow medium to flow from top to bottom, a slow flow hole 74 is provided in the middle of the buffer block 7 and extends to the connecting rod 71, a plurality of diversion holes 75 connected to the slow flow hole 74 are provided on the peripheral side of the connecting rod 71 near one end of the buffer block 7, the aperture of the slow flow hole 74 is much larger than that of the diversion hole 75, and a flared portion is provided on the end of the slow flow hole 74 away from the connecting rod 71. Moreover, when the buffer block 7 moves up to contact the upper cavity wall of the sliding cavity 61, there is a gap between the permanent magnet 42 and the adjacent electromagnet 43 on the control console 5. Specifically, a limit ring 31 is provided on the upper part of the sliding sleeve 3. When the sliding block 6 moves up to contact the limit ring 31 and the buffer block 7 moves up to contact the upper cavity wall of the sliding cavity 61, there is still a gap between the permanent magnet 42 and the corresponding electromagnet 43. On the one hand, the stamping module is transferred among the three stations of the die lifting area 51.

[0040] In this way, when the stamping module follows the turntable 2 to rotate into the die area 52, Figure 4 The permanent magnet 42 is subjected to the magnetic repulsion force from the electromagnet 43, so that the permanent magnet pushes the buffer block 7 and the slider 6 to move downward in the sliding sleeve 3. When the punch head 41 hits the glass paste in the lower mold 8, the permanent magnet continues to move downward, mainly pushing the buffer block 7 to slide in the sliding cavity 61 of the slider 6, which can ensure that the punch head 41 applies a certain pressure to the glass paste in the lower mold 8 while significantly reducing the pressing speed of the punch head 41; furthermore, when the slider 6 slides downward in the sliding cavity 61, the flowing medium in the lower part of the sliding cavity 61 passes through the slow flow hole 74 and flows to the upper part of the sliding cavity 61 through multiple diversion holes 75, which can have a good buffering effect on the sliding of the buffer block 7 in the slider 6, that is, it can have a good buffering effect when the punch head punches the glass paste in the lower mold 8. When the flowing medium in the lower part of the slide cavity 61 completely enters the upper part of the slide cavity 61, the buffer block 7 directly pushes the slider 6 to drive the punch head 41 to move downward, which can be well matched with the setting of gradually increasing magnetic field strength in the die area 52 to ensure high-quality stamping processing of glassware.

[0041] When the punching module follows the turntable 2 to rotate to the holding area 53, the pressing force of the punch head 41 on the glassware in the lower mold 8 is maintained unchanged to release the internal stress of the glassware after being punched as much as possible, and then the pressing force is gradually reduced, which can facilitate the separation of the glassware from the lower mold 8 and the punch head 41 to avoid adhesion and difficulty in removing the material. Figure 3, the permanent magnet 42 is lifted up under the action of magnetic attraction, so that the buffer block 7 moves up relatively in the slider 6. At this time, the flowing medium in the upper part of the slide cavity 61 quickly flows to the lower part of the slide cavity 61 through the one-way valve 73 until the buffer block 7 completely supports the upper cavity wall of the slide cavity 61. At this time, the buffer block 7 drives the slider 6 to continue to move up until the slider 6 is limited by the limit block, and the lifting operation of the punch head 41 can be completed to facilitate material removal or the addition of new glass paste; and by controlling the distance between the two adjacent electromagnets 43 in the mold lifting area 51, it can also be ensured that the punch head 41 can always remain in the lifted state and not fall when transferring in the mold lifting area 51.

[0042] The implementation principle of a punching mechanism for manufacturing lightweight glassware in the embodiment of the present application is as follows:

[0043] When the stamping mechanism of the present application is working, the glass paste feeding tube conveys the molten hot glass paste to one of the lower molds 8 corresponding to the mold lifting area 51, and the lower mold 8 is conveyed to the die pressing area 52 when the turntable 2 rotates. The electromagnet 43 in the die pressing area 52 generates a magnetic field with the same magnetic property as the permanent magnet 42, so that the permanent magnet 42 can push the punch head 41 to move downward quickly in the sliding sleeve 3, and punch the glass paste in the lower mold 8 below; by controlling the magnetic field strength generated by the electromagnet in the die pressing area 52, the impact force of the punch head 41 can be adjusted, the stamping processing quality of the glassware can be accurately controlled, and when replacing glassware of different thicknesses or producing glassware with different stamping requirements, it is easier to adjust the impact force of the punch head 41.

[0044] Furthermore, by arranging the electromagnets 43 in the die area 52 in a number greater than the number of the stamping modules, the magnetic field to which the permanent magnets 42 are subjected when passing through the die area 52 can be as stable as possible without interruptions, thereby ensuring the stamping stability of the stamping head 41. When the turntable 2 continues to rotate until the lower mold 8 is transported to the pressure holding area 53, the magnetic repulsion force generated by the multiple electromagnets 43 in the pressure holding area 53 also pushes the stamping head 41 to maintain a certain downward pressure, thereby ensuring the continuous production of the stamping mechanism and maintaining the pressure and cooling the glassware after stamping, thereby effectively ensuring the processing quality of the glassware.

[0045] When the pressure holding is completed, the turntable 2 continues to rotate until the lower mold 8 is transported to the mold lifting area 51. At this time, the electromagnet 43 in the mold lifting area 51 generates a magnetic attraction to the permanent magnet 42, so that the permanent magnet 42 drives the punch head 41 to lift up, and demoulding, material removal and feeding operations can be performed in sequence. By analogy, when N stamping modules are provided on the turntable 2, at full speed, the stamping mechanism of the present application can simultaneously perform stamping and manufacturing of N glassware, which greatly improves the processing efficiency of stamped glassware; if the factory has a small number of orders but cannot be shut down, it is only necessary to control the working frequency of the glass paste feeding tube and the material removal robot arm. Therefore, the stamping mechanism of the present application can also flexibly switch between different production speeds without increasing or decreasing the overall components or molds, and there is no no-load damage to the moving parts of the stamping mechanism.
