Description

Technical Field

[0001] The invention belongs to the technical field of mold processing, and in particular relates to a processing device for a double-sheet glass forming mold. Background Art

[0002] At present, the front and rear windshields and window glasses on domestic cars are all manufactured using molds. The production process of the single-mold double-piece glass used in cars requires the use of molds. In the automotive industry, due to the frequent updates of new brand vehicles and new orders, glass manufacturers need to manufacture glass of different specifications in a short period of time. Molds that can process glass of different specifications are needed to achieve continuous supply to automobile manufacturers. At this time, the mold processing factory needs to produce molds of this specification overnight.

[0003] The existing technology has the following deficiencies:

[0004] (1) Existing mold production equipment requires punching holes around the mold to fix the two molds. Generally, the positions of the mold holes are relatively fixed, but the specifications of the molds are often changed according to the glass models to be produced. If different mold specifications are used for punching, the corresponding mold production equipment needs to be replaced, which affects the efficiency of mold production and the cycle of glass production.

[0005] (2) At the same time, when the mold production equipment punches holes around the mold, the iron chips are also sucked away in the form of gas. However, the existing iron chip suction is usually in the form of a pipe sucking near the punching position. Sometimes the suction is too small and the range is too small to clean, or the suction is too strong, resulting in a waste of electricity.

[0006] Therefore, this solution aims to solve the technical problem of how to efficiently remove drilling debris during the glass mold production process. Summary of the Invention

The suction ring is set at the position of the top inner wall of the outer limit ring, the sliding block is embedded in the internal thread, the top of the main air suction hole is connected and communicated with the air pipe, the position of the suction ring is sleeved on the periphery of the drill bit and slightly above it, and the surrounding area of ​​the suction ring will always fit the inner wall of the outer limit ring when it moves up and down.

[0015] The drilling chip cleaning assembly also includes a rotating cleaning structure for removing large-volume metal chips;

[0016] The rotary cleaning structure includes a positioning plate horizontally arranged on the driving shaft, a driving gear coaxially arranged on the driving shaft, a plurality of driven gears arranged in an annular array and meshing with each other on the outside of the driving gear, an upper rotating cylinder coaxially arranged on the bottom surface of the driven gear, a lower rotating cylinder coaxially arranged below the upper rotating cylinder, and a spring arranged between the upper rotating cylinder and the lower rotating cylinder. A plurality of guide pillars are vertically arranged on the lower end surface of the upper rotating cylinder. The spring is sleeved on the outside of the guide pillars, and the two ends of the spring are respectively connected to the upper rotating cylinder and the lower rotating cylinder.

[0017] The two ends of the driving shaft are connected to the motor and the drill bit respectively, and the top surface of the positioning plate is connected to the mounting plate.

[0018] A through hole 1 is provided at the center of the driven gear, the bottom surfaces of the upper rotating cylinder and the lower rotating cylinder are both open, the upper rotating cylinder is connected to the through hole 1, a gear shaft is provided at the center of the driven gear, and a through hole 2 is provided at the center of the gear shaft, one end of the gear shaft is connected to the through hole 1, and the other end thereof is connected to the trachea via a conduit;

[0019] A retractable bellows is provided between the upper rotating cylinder and the lower rotating cylinder, and the upper and lower ends of the bellows are connected to the bottom of the upper rotating cylinder and the top of the lower rotating cylinder respectively.

[0020] The positive effects of the present invention are as follows:

[0021] (1) The mold to be drilled is placed on the top workbench of the processing device body and placed between two sets of oppositely arranged adjustment and fixing components. Then, the staff manually rotates the screw and the bidirectional threaded rod to adjust the position of the internal thread plate 2 and the internal thread plate 3, so that the internal thread plate 2 and the internal thread plate 3 slide from the two sides and the top to the middle through the four sets of right-angle plates in the direction of the four corners of the mold until the four corners of the mold are clamped, thereby improving the convenience and installation efficiency of fixing molds of different specifications;

[0022] (2) When the suction box rotates, the suction force in the annular space at the bottom of the suction box will be used to suck the iron chips into the main suction hole through the auxiliary suction hole opened through the suction ring, thereby increasing the suction force of the auxiliary suction hole at the bottom of the suction ring on the iron chips. At the same time, the rotating suction box will rotate while the hydraulic cylinder drives the motor downward to drive the drill bit to drill holes. There is no need to adjust the power of the air pump, but the suction force is increased by the suction ring. At the same time, through the cooperation between the sliding block and the inner thread of the inner wall of the outer limit ring, it follows and rotates around the drill bit as it moves downward, continuously and accurately sucking air around the drill bit, thereby improving the cleaning range and cleaning effect of the iron chips.

[0023] (3) This solution is equipped with a rotating cleaning structure, which has the following technical effects:

[0024] First, when the metal debris is large in volume, it is difficult to be sucked away by the air pipe, and a large amount of metal debris may be concentrated around the drill hole, causing inconvenience in subsequent cleaning. Therefore, under the rotation of the driven gear, the lower rotating drum is driven to rotate. The bottom surface of the lower rotating drum can efficiently roll out the metal debris through friction, thus achieving the removal of large-volume metal debris;

[0025] Secondly, by providing through holes in the upper and lower rotating cylinders, metal debris can be sucked into the air pipe;

[0026] Third, a retractable bellows is provided between the upper and lower rotating cylinders. This not only ensures that the upper and lower rotating cylinders can move toward each other, but also seals the upper and lower rotating cylinders, facilitating the extraction of metal debris. Furthermore, since the upper and lower rotating cylinders are connected by a spring, the connection may be unstable. In this case, the bellows are connected to the upper and lower rotating cylinders at both ends, respectively, to prevent separation of the upper and lower rotating cylinders to a certain extent.

[0027] (4) The present invention reduces electricity costs and improves the suction force for cleaning iron chips without increasing the power of the air pump, thereby reducing the production cost of the mold, improving the production efficiency of the mold and the cleaning effect of the iron chips, and increasing the revenue of the mold processing factory.

[0037] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods. Example

[0038] Refer to the attached Figure 1-6 The present invention provides a processing device for a double-piece glass forming mold, comprising a processing device body 1, a side panel 10 being installed on the top of the processing device body 1, an air pump 11 being provided on the inner wall of the top of the side panel 10, a chip discharge pipe 12 being installed on the output end of the air pump 11, a telescopic hose 13 being installed on the input end of the air pump 11, and an air pipe 14 being provided on one end of the telescopic hose 13; and an adjusting and fixing component 2, the adjusting and fixing component 2 being installed on the top of the processing device body 1, and the adjusting and fixing component 2 being used to adjust and fix the mold; and a drilling and chip cleaning component 3, the drilling and chip cleaning component 3 being provided on the top of the adjusting and fixing component 2, and the drilling and chip cleaning component 3 being used to drill holes in the mold and absorb iron chips left by drilling.

[0039] Furthermore, the adjustment and fixing assembly 2 includes an internal threaded plate 20, the inner wall of the internal threaded plate 20 is threadedly connected to the screw 21, the end of the screw 21 is provided with an internal threaded plate 22, the outer surface of the internal threaded plate 22 is threadedly connected to the bidirectional threaded rod 23, and a right-angle plate 25 is installed on one side of the internal threaded plate 3 24. The internal threaded plate 20 is fixedly installed on the top of the processing device body 1, and the internal threaded plate 22, the internal threaded plate 3 24 and the right-angle plate 25 are all slidably connected to the top of the processing device body 1.

[0040] During work, first, the staff places the mold to be drilled on the top workbench of the processing device body 1 and places it between the two sets of oppositely arranged adjustment and fixing components 2. Then, the staff adjusts the positions of the internal thread plate 22 and the internal thread plate 3 24 by manually turning the screw 21 and the two-way threaded rod 23, so that the internal thread plate 22 and the internal thread plate 3 slid from the two sides and the top to the middle through the four sets of right-angle plates 25 in the direction of the four corners of the mold until the four corners of the mold are clamped, and at the same time, the drilling and chip cleaning component 3 is driven to adjust the position. Without affecting the drilling position of the mold, the mold is now firmly clamped and fixed on the workbench at the top of the processing device body 1. When replacing molds of other models and specifications for drilling, the staff adjusts them by turning the screw 21 and the two-way threaded rod 23 again, thereby improving the convenience and installation efficiency of fixing molds of different specifications.

[0041] Furthermore, the drilling and chip cleaning assembly 3 includes an L-shaped plate 30, which is arranged on the top of the right-angle plate 25. A hydraulic cylinder 31 is installed on the inner wall of the top of the L-shaped plate 30. A mounting plate 32 is provided at the output end of the hydraulic cylinder 31. A motor 33 is installed at the bottom of the mounting plate 32. A drill bit 34 is provided at the output end of the motor 33. A suction box 35 is provided at the bottom end of the mounting plate 32. A main suction hole 36 is opened on the outer surface of the top of the suction box 35. A bearing 37 is installed at the bottom end of the suction box 35. A suction ring 38 is provided at the bottom of the bearing 37. An auxiliary suction hole 39 is opened on the upper end surface of the suction ring 38.

[0042] A sliding block 390 is provided on one side of the suction ring 38, an outer limiting ring 391 is installed on the inner side of the L-shaped plate 30, and an inner wall of the outer limiting ring 391 is provided with an internal thread 392. The suction box 35 and the suction ring 38 fit tightly together, and the bottom of the suction box 35 is provided with an annular opening. The suction ring 38 is rotatably connected to the suction box 35 via a bearing 37. The number of auxiliary air suction holes 39 is provided in multiple groups, and the multiple groups of auxiliary air suction holes 39 are provided in an annular array on the upper end surface of the suction ring 38 and pass through the suction ring 38 (specifically, the multiple groups of auxiliary air suction holes 39 are distributed at equal angles on the upper end of the suction ring 38 and pass through the suction ring 38, that is, are provided on the upper end surface of the suction ring 38). The suction ring 38 is located at the top of the inner wall of the outer limiting ring 391, and the sliding block 390 is embedded in the internal thread 392;

[0043] The top of the main air intake hole 36 is connected to and communicates with the air pipe 14. The suction ring 38 is positioned so as to be sleeved on the outer periphery of the drill bit 34 and slightly above the drill bit 34. When the suction ring 38 moves up and down, the surrounding area will always be in contact with the inner wall of the outer limit ring 391.

[0044] In actual use, when drilling holes in the mold, the hydraulic cylinder 31 extends the motor 33 and the drill bit 34 at the bottom of the mounting plate 32 downward until the drill bit 34 drills four corresponding holes on the mold surface. When the mounting plate 32 descends, the suction box 35 is also driven to move downward inside the outer limit ring 391. Since a sliding block 390 is installed on one side of the suction box 35 and engages with the internal thread 392, when the sliding block 390 moves downward, it slides against the inner wall of the internal thread 392 and rotates according to the texture of the internal thread 392, driving the suction box 35 itself to rotate at the bottom of the suction box 35 through the bearing 37.

[0045] At the same time, the air pump 11 started by the staff sucks air through the telescopic hose 13 and the air pipe 14 and the main air suction hole 36 connected to the top of the suction box 35. Since the bottom of the suction box 35 is set in an annular opening shape, when the suction box 35 rotates, the suction force in the annular space at the bottom of the suction box 35 will be used to suck the iron filings into the main air suction hole 36 through the auxiliary air suction hole 39 opened by the suction ring 38. Since the auxiliary air suction hole 39 reduces the area of ​​the gas sucked upward in the suction box 35, and the suction box 35 and the suction ring 38 are tightly fitted, the suction force of the auxiliary air suction hole 39 at the bottom of the suction ring 38 on the iron filings can be improved.

[0046] Regarding how to increase the pressure, specifically, because the air pump 11 sucks air through the telescopic hose 13 and the air pipe 14 and the main suction hole 36 connected to the top of the suction box 35, the suction box 35 and the suction hole 39 are similar to the syringe structure. The suction space of the upper suction box is large, and the suction space to the lower suction hole 39 is very small, similar to the smaller the opening at the front end of the syringe, the more concentrated the suction force, and the greater the suction force. The larger the opening, the looser the suction force, and the greater the suction force.

[0047] At the same time, the rotating suction box 35 will rotate by cooperating between the sliding block 390 and the internal thread 392 on the inner wall of the outer limit ring 391 while the hydraulic cylinder 31 drives the motor 33 downward to drive the drill bit 34 to drill a hole, and move downward with the drill bit 34 until it reaches the mold surface, and then moves back upward. When the drill bit 34 is drilling a hole, the iron chips around the drill bit 34 are accurately and continuously sucked in, and finally enter the air pump 11 through the chip discharge pipe 12 for discharge and collection. (The function of the telescopic hose 13 is to adaptively extend and retract when the fixing component 2 is adjusted and fixed to the mold and when the top drilling and chip washing component 3 moves). It does not require additional electricity to drive, and does not need to adjust the power of the air pump 11. Instead, it rotates around the drill bit 34 by increasing the suction force through the suction ring 38, thereby improving the cleaning range and cleaning effect of the iron chips. Example

[0048] See also Figure 7-Figure 8, the drilling chip cleaning assembly also includes a rotating cleaning structure for removing large-volume metal chips;

[0049] The rotary cleaning structure includes a positioning plate 332 horizontally arranged on the drive shaft 331, a driving gear 330 coaxially arranged on the drive shaft 331, a plurality of driven gears 334 arranged in an annular array and meshing with the outer side of the driving gear 330, an upper rotating cylinder 335 coaxially arranged on the bottom surface of the driven gear 334, a lower rotating cylinder 337 coaxially arranged below the upper rotating cylinder 335, and a spring 339 arranged between the upper rotating cylinder 335 and the lower rotating cylinder 337. The lower end surface of the upper rotating cylinder 335 is vertically provided with a plurality of guide pillars 338. The spring 339 is sleeved on the outer side of the guide pillars 338. The two ends of the spring 339 are respectively connected to the upper rotating cylinder 335 and the lower rotating cylinder 337.

[0050] Both ends of the driving shaft 331 are connected to the motor 33 and the drill bit 34 respectively, and the top surface of the positioning plate 332 is connected to the mounting plate 32 .

[0051] A through hole 1 is provided at the center of the driven gear 334. The bottom surfaces of the upper rotating cylinder 335 and the lower rotating cylinder 337 are both open. The upper rotating cylinder 335 is connected to the through hole 1. A gear shaft 333 is provided at the center of the driven gear 334. A through hole 2 is provided at the center of the gear shaft 333. One end of the gear shaft 333 is connected to the through hole 1, and the other end is connected to the trachea via a conduit.

[0052] A retractable bellows 336 is provided between the upper rotating cylinder 335 and the lower rotating cylinder 337 , and the upper and lower ends of the bellows 336 are connected to the bottom of the upper rotating cylinder 335 and the top of the lower rotating cylinder 337 respectively.

[0053] During the operation of the drill bit 34, the bottom end of the lower rotating cylinder 337 gradually contacts the upper end surface of the mold. Under the action of the downward pressure, the lower rotating cylinder 337 rotates while moving closer to the upper rotating cylinder 335. The spring 339 is compressed, and under the suction action of the air pipe 14, a large amount of large metal debris is sucked away.

[0054] It should be noted that a motor 33 and a drill bit 34 are respectively provided at both ends of the drive shaft 331. The upper end surface of the positioning plate 332 can be fixedly connected to the bottom surface of the mounting plate 32 through connecting ribs. In order to simplify the design, they are no longer marked in detail in the accompanying drawings. The principle is to ensure that the positioning plate 332 is fixed.

[0055] This application converts the dust suction device into a chip suction device. Although the drilling device in the prior art is generally provided with a waste chip collection box or trough, and coolant is used for cooling and flushing during drilling, the construction environment is not safe and hygienic, and cleaning is extremely inconvenient. This solution has other unexpected technical effects under the premise of safety and hygiene, which will not be described in detail here.

[0056] Technical features not described in the present invention can be achieved through or by adopting existing technologies and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
