Description

Technical Field

[0001] This utility model belongs to the technical field of sealing strip processing equipment, specifically relating to a device for forming the end of automotive glass grooves. Background Technology

[0002] Automotive glass channels are divided into integrated decorative strip glass channels and integrated rubber exterior glass channels. Among them, the integrated rubber exterior glass channels are simpler in terms of materials and manufacturing process than the former. They are more resistant to dirt and oxidation and are less prone to scratches. They also help reduce visual interference and improve driving safety.

[0003] Currently, the end forming process of rubber-integrated automotive glass channels usually adopts sawing. The disadvantage is that the sawing process generates sawdust, so an additional step of blowing air to clean the sawdust is required, which leads to a deterioration of the production environment, a longer production cycle, and is not conducive to achieving clean and efficient production. In addition, the sawing forming quality is poor, which can easily affect the quality of subsequent end joining. Utility Model Content

[0004] This utility model provides an automotive glass groove end forming device, which aims to avoid the problem of sawdust generation in the automotive glass groove end forming process and improve the end forming efficiency and quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automotive glass groove end forming device is provided, comprising a frame and at least one punching unit mounted on the frame; the punching unit includes a telescopic drive member and a port module connected to the frame; the output end of the telescopic drive member is connected to a punching cutter; the port module includes a fixed mold and a moving mold, the fixed mold being fixed to the frame, and the moving mold being connected to the output end of the telescopic drive member; wherein, under the drive of the telescopic drive member, the moving mold cooperates with the fixed mold to clamp the glass groove and form a flat die opening, and the punching cutter cuts the glass groove along the flat die opening under the drive of the telescopic drive member.

[0006] In some embodiments, the fixed mold has a side support portion and a bottom support portion; the moving mold includes a side pressing module and a top pressing module. The side pressing module is used to press the glass trough laterally against the side support portion under the drive of the telescopic drive member, and the top pressing module is used to press the glass trough downward against the bottom support portion under the drive of the telescopic drive member.

[0007] In some embodiments, the output end of the telescopic drive is slidably fitted with a slide rod along its telescopic direction, and the pressing module is connected to the lower end of the slide rod; the top end of the slide rod has a limiting part, and an elastic element is sleeved on the slide rod, which is used to elastically push the pressing module downward.

[0008] For example, a guide seat is connected to the fixed mold, and the top pressing module is slidably connected to the guide seat along the telescopic drive component.

[0009] For example, the bottom of the fixed mold is provided with a first groove, and the bottom support is fitted into the first groove; a second groove is formed between the fixed mold and the guide seat, and the side support is fitted and fixed into the second groove.

[0010] In one possible implementation, the output end of the telescopic drive is connected to a tool holder, and the punching tool is detachably connected to the tool holder; the tool holder is provided with a guide post, which extends along the telescopic direction of the telescopic drive and slides through the side support.

[0011] In some embodiments, a groove is provided at the part of the fixed mold located on the side of the flat mold opening, and the side pressure module is slidably connected to the groove; the output end of the telescopic drive is fixedly connected to a guide rod along its telescopic direction, the guide rod is connected to the side pressure module and drives the side pressure module to move along the groove to press against the glass cloth groove.

[0012] For example, the side pressure module is provided with a guide hole that extends through the axial direction of the guide rod; a first wedge and a second wedge are respectively provided on two opposite side walls of the guide rod along the extension direction of the slide groove; wherein, when the telescopic drive member drives the guide rod to move downward, the first wedge abuts against the hole wall of the guide hole to drive the side pressure module to press the glass groove; when the telescopic drive member drives the guide rod to move upward, the second wedge abuts against the other hole wall of the guide hole to drive the side pressure module to release the glass groove.

[0013] For example, the upper end of the guide hole wall near the side support is provided with a first inclined guide surface, and the lower end of the guide hole wall away from the side support is provided with a second inclined guide surface.

[0014] In some embodiments, a feed guide is connected to the frame, the feed guide having a guide hole for guiding the glass cloth groove between the fixed mold and the moving mold.

[0015] The beneficial effects of the automotive glass channel end forming device provided by this utility model are as follows: Compared with the prior art, the end forming device of this utility model uses punching to form the glass channel end, which avoids the generation of sawdust and debris compared with sawing. This not only saves the process of blowing and cleaning sawdust, reducing the production cycle, but also helps to maintain a clean production environment and achieve clean production. During the production process, the glass channel can be manually or automatically fed between the moving mold and the fixed mold. Then, the telescopic drive component drives the moving mold to move, so that the moving mold and the fixed mold cooperate to clamp the glass channel. After clamping the glass channel, a neat flat die opening is formed on the end face of the same end of the moving mold and the fixed mold. With the further movement of the telescopic drive component, the punching tool drives the punching tool to cut the glass channel along the flat die opening. The clamping and punching of the glass channel can be completed simultaneously during the entire punching process. Compared with the end sawing forming method, not only is the production efficiency greatly improved, but the cooperation between the punching tool and the flat die opening can avoid the problems of misalignment and burrs in the cut, thus improving the forming accuracy and quality.

[0016] The side-pressure module presses against the glass groove from the side, and the top-pressure module presses against the glass groove from the top, thus forming a 360-degree clamping and fixing of the glass groove in both horizontal and vertical directions. This prevents the glass groove from deforming under stress during the punching process, which would affect the cut quality. The side-pressure module can be moved away from the side support part by the telescopic drive component, and the top-pressure module can be moved away from the bottom support part by the telescopic drive component. This allows the glass groove to smoothly enter between the moving mold and the fixed mold, improving the feeding smoothness of the port module.

[0017] The combination of the limiting part and the elastic element enables the top pressing module to press the glass groove before the punching tool contacts the glass groove, and maintain the pressing state on the glass groove until the punching tool cuts the glass groove and disengages from the flat die, thereby improving the stability of the punching process and the quality of the end cut.

[0018] By guiding and constraining the top pressing module through the guide seat, the motion stability of the top pressing module under the drive of the telescopic drive component is improved, thereby improving the alignment accuracy between the top pressing module and the fixed mold. This ensures the neatness of the flat mold opening and is beneficial to improving the end cut quality of the glass trough.

[0019] The bottom support and side support, which serve as the support parts for the glass channel of the fixed mold, can be disassembled and replaced from the fixed mold. Therefore, for different glass channel structures, only the corresponding side support and bottom support need to be replaced, without replacing the entire fixed mold. This can reduce the mold making cost while increasing the adaptability of the fixed mold.

[0020] By using the tool holder as the mounting base for the punching tool, the connection reliability of the punching tool is improved; the sliding fit between the guide post and the side support part forms a motion guide for the tool holder, thereby improving the motion accuracy of the punching tool and improving the end punching quality of the glass trough.

[0021] The side-pressure module is slidably connected in the groove and can move closer to or away from the glass groove under the drive of the guide rod. This allows the glass groove to easily extend between the moving mold and the fixed mold, and also allows the glass groove to be clamped and fixed during the punching process. The structure is simple and compact, and can complete the fixing and punching of the glass groove in one reciprocating motion of the telescopic drive, thereby improving work efficiency.

[0022] The guide rod drives the side pressure module by using the first and second wedges to laterally press against the wall of the guide hole. The structure is compact and reliable, and the action sequence of the side pressure module and the punching tool can be controlled from the perspective of mechanical structure. It is not only highly reliable, but also reduces the difficulty and cost of electrical control.

[0023] By setting the first inclined guide surface, the first wedge can be transitionally guided, so that the part of the guide rod with the first wedge can be smoothly inserted into the guide hole. The second inclined guide surface is set to provide transitional guidance for the second wedge, so as to avoid the second wedge from getting stuck with the lower end of the guide hole and affecting the smoothness of movement.

[0024] The feed cutter holder can constrain the unconstrained glass trough into a contracted state, thereby improving the smoothness of the glass trough feeding between the moving mold and the fixed mold. Attached Figure Description

[0034] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0036] Please refer to the following: Figures 1 to 8The present invention provides a device for forming the end of a glass channel in automotive applications. The device includes a frame 10 and at least one punching unit mounted on the frame 10. The punching unit includes a telescopic drive 20 connected to the frame 10 and a port module 30. A punching cutter 40 is connected to the output end of the telescopic drive 20. The port module 30 includes a fixed mold 31 and a moving mold 32. The fixed mold 31 is fixed to the frame 10, and the moving mold 32 is connected to the output end of the telescopic drive 20. Under the drive of the telescopic drive 20, the moving mold 32 cooperates with the fixed mold 31 to clamp the glass channel 50 and form a flat die opening 300. The punching cutter 40 cuts the glass channel 50 along the flat die opening 300 under the drive of the telescopic drive 20.

[0037] It should be noted that in this embodiment, a single punching unit can be installed on the rack 10, or two or more punching units can be installed at the same time. An aviation socket is provided on the rack 10 to facilitate power supply to the punching unit.

[0038] In this embodiment, the telescopic drive component 20 can be a cylinder, a hydraulic cylinder, or an electric push rod. Considering the speed and ease of driving the punching action, a cylinder is preferred as the telescopic drive component 20.

[0039] In this embodiment, the port module 30 reliably clamps the glass groove 50 and forms a neat flat die opening 300. In this way, the punching tool 40 can move closely to the flat die opening 300 under the drive of the telescopic drive 20 to achieve precise punching of the glass groove 50. This ensures that the cut is flat and burr-free. Of course, the punching process will not produce sawdust problems similar to those in sawing processes.

[0040] In this embodiment, both the fixed mold 31 and the moving mold 32 can be integral modules or combinations of two or more modules. Considering the ease of processing and the smoothness of the glass trough 50 extending into and exiting the fixed mold 31 and the moving mold 32, it is preferable to use multiple modules to form the fixed mold 31 and the moving mold 32. For example, for the cross-sectional structure of the glass trough 50, the fixed mold 31 may include a part of the module extending into and supporting the inside of the trough and a part of the module supporting the side of the glass trough 50, while the moving mold 32 may include a part of the module for pressing against the top of the glass trough 50 and another part of the module for laterally pressing against the glass trough 50. In this way, both horizontal and vertical clamping of the glass trough 50 can be achieved simultaneously, thereby ensuring the stability of the fixed state of the glass trough 50. Moreover, it is also convenient for the glass trough 50 to extend into or exit after the moving mold 32 is separated from the fixed mold 31, which facilitates automated control.

[0041] It should be explained that, considering that the end of the glass groove 50 is usually a beveled cut, in this embodiment, the flat die opening 300 formed by the moving die 32 and the fixed die 31 can be set as a beveled surface that is inclined relative to the axial direction of the glass groove 50. At the same time, the punching tool 40 moves up and down along the flat die opening 300 under the drive of the telescopic drive member 20, thereby directly cutting out an end cut that matches the design angle.

[0042] The automotive glass channel end forming device provided in this embodiment, compared with the prior art, uses punching to form the end of the glass channel 50, which avoids the generation of sawdust compared to sawing. This not only saves the step of blowing to clean the sawdust and reduces the production cycle, but also helps to maintain a clean production environment and achieve clean production. During the production process, the glass channel 50 can be manually or automatically fed between the moving mold 32 and the fixed mold 31. Then, the telescopic drive 20 drives the moving mold 32 to move, so that the moving mold 32 and the fixed mold 31 cooperate to clamp the glass channel 50. After clamping the glass lining groove 50, a neat flat die opening 300 is formed on the end face of the same end of the moving mold 32 and the fixed mold 31. With the further movement of the telescopic drive component 20, the punching cutter 40 drives the glass lining groove 50 to cut along the flat die opening 300. The clamping and punching of the glass lining groove 50 can be completed simultaneously during the entire punching process. Compared with the end sawing forming method, not only is the production efficiency greatly improved, but the cooperation between the punching cutter 40 and the flat die opening 300 can avoid the problem of misalignment and burrs in the cut, and improve the forming accuracy and quality.

[0043] In some embodiments, see Figures 4 to 7 The fixed mold 31 has a side support portion 311 and a bottom support portion 312; the moving mold 32 includes a side pressing module 321 and a top pressing module 322. The side pressing module 321 is used to press the glass groove 50 laterally against the side support portion 311 under the drive of the telescopic drive member 20, and the top pressing module 322 is used to press the glass groove 50 downward against the bottom support portion 312 under the drive of the telescopic drive member 20.

[0044] The fixed mold 31, based on its bottom support 312 and side support 311, can provide bidirectional support for the bottom and one side of the glass groove 50. On this basis, the side pressure module 321 laterally presses against the glass groove 50, and the top pressure module 322 presses against the glass groove 50 downwards, thereby forming a comprehensive clamping and fixing of the glass groove 50 in both horizontal and vertical directions, preventing deformation of the glass groove 50 during punching and affecting the cut quality. Furthermore, the side pressure module 321 can move away from the side support 312 under the action of the telescopic drive 20. 11. The top pressure module 322 can move away from the bottom support 312 under the drive of the telescopic drive 20, thereby facilitating the smooth entry of the glass trough 50 into the space between the moving mold 32 and the fixed mold 31. After the glass trough 50 enters, the side pressure module 321 and the top pressure module 322, based on the reverse action of the telescopic drive 20, respectively cooperate with the side support 311 and the bottom support 312 to clamp the glass trough 50. This reduces the resistance of the glass trough 50 entering the space between the fixed mold 31 and the moving mold 32, and improves the feeding smoothness of the port module 30.

[0045] It is important to understand that the groove of the glass lining 50 needs to be stably supported to ensure the quality of its end cut. Therefore, the bottom support part 312 has a support rib 3121 that extends into the groove of the glass lining 50. The support rib 3121 supports the groove of the glass lining 50, thereby preventing the groove of the glass lining 50 from being crushed and deformed during the punching process, which would affect the forming quality.

[0046] For some possible implementations, please refer to [link / reference]. Figure 4 and Figure 5 The output end of the telescopic drive component 20 is slidably connected to the slide rod 21 along its telescopic direction, and the top pressing module 322 is connected to the lower end of the slide rod 21; the top end of the slide rod 21 has a limiting part 211, and an elastic element 212 is sleeved on the slide rod 21. The elastic element 212 is used to elastically push the top pressing module 322 downward.

[0047] When the output end of the telescopic drive 20 moves downward, the pressing module 322 presses down against the glass groove 50. As the output end of the telescopic drive 20 continues to move downward, the slide bar 21 begins to slide relative to the output end of the telescopic drive 20. The elastic element 212 is gradually compressed, and the elastic pressing force of the pressing module 322 on the glass groove 50 gradually increases, thus clamping the glass groove 50. At the same time, the punching cutter 40 begins to cut the glass groove 50 under the drive of the telescopic drive 20. After cutting, the output end of the telescopic drive 20 begins to move in the direction of contraction. At this time, the punching cutter 40 first rises, and the pressing module 322 continues to press against the glass groove 50 based on the pushing action of the elastic element 212 until the punching cutter 40 disengages from the flat die 300. Then, the limiting part 211 at the top of the slide bar 21 abuts against the output end of the telescopic drive 20, thereby driving the pressing module 322 to release the glass groove 50, so as to facilitate the smooth extraction of the glass groove 50.

[0048] The cooperation of the limiting part 211 and the elastic element 212 enables the top pressing module 322 to press the glass lining groove 50 before the punching cutter 40 contacts the glass lining groove 50, and to maintain the pressing state on the glass lining groove 50 until the punching cutter 40 cuts the glass lining groove 50 and then leaves the flat die opening 300, thereby improving the stability of the punching process and the quality of the end cut.

[0049] For example, the elastic element 212 is a spring, and the slide rod 21 is a smooth rod with a protrusion at the top as a limiting part 211. The lower end of the slide rod 21 is provided with an external thread and screwed to the top pressing module 322. The output end of the telescopic drive member 20 has a through hole for the slide rod 21 to pass through, and the size of the limiting part 211 is larger than the through hole. Further, the limiting part 211 can be an adjusting nut threaded to the top of the slide rod 21. By turning the adjusting nut, the distance between the top pressing module 322 and the output end of the telescopic drive member 20 can be adjusted, thereby adjusting the displacement of the top pressing module 322 away from the fixed mold 31 and releasing the glass lining groove 50 under the drive of the telescopic drive member 20, and improving the flexibility of use.

[0050] To improve the motion stability of the top pressure module 322, such as Figures 5 to 7As shown, a guide seat 60 is connected to the fixed mold 31, and the top pressing module 322 is slidably connected to the guide seat 60 along the telescopic drive 20. The guide seat 60 can be fixed to the fixed mold 31 by screw connection. The top pressing module 322 can be provided with T-shaped or dovetail-shaped sliding ribs, and the guide seat 60 is correspondingly provided with T-shaped grooves or dovetail grooves, thereby realizing the sliding connection of the top pressing module 322 on the fixed mold 31. The guide seat 60 guides and constrains the movement of the top pressing module 322, thereby improving the movement stability of the top pressing module 322 under the drive of the telescopic drive 20, and thus improving the alignment accuracy between the top pressing module 322 and the fixed mold 31. This ensures the neatness of the flat mold opening 300 and is beneficial to improving the end cut quality of the glass duct 50.

[0051] Specifically, please see Figure 6 and Figure 7 In this embodiment, the bottom of the fixed mold 31 is provided with a first groove 313, and the bottom support part 312 is fitted into the first groove 313; a second groove 314 is formed between the fixed mold 31 and the guide seat 60, and the side support part 311 is fitted and fixed into the second groove 314.

[0052] The bottom support 312 and the side support 311, which serve as the support parts of the fixed mold 31 for the glass trough 50, can be disassembled and replaced from the fixed mold 31. Thus, for different glass trough 50 structures, only the corresponding side support 311 and bottom support 312 need to be replaced, without having to replace the entire fixed mold 31. This reduces the mold-making cost while increasing the adaptability of the fixed mold 31.

[0053] The first groove 313 is mainly used to provide positioning constraints for the bottom support 312. Based on this, the bottom support 312 can be further fixed in the first groove 313 by fasteners such as screws. Similarly, the second groove 314 is used to provide positioning for the side support 311. Based on this, the side support 311 can be further fixed in the second groove 314 by fasteners. The above connection method can not only ensure the stable and reliable connection between the bottom support 312 and the side support 311, but also improve the installation position accuracy of the two on the fixed mold 31, thereby improving the clamping and fixing reliability of the glass trough 50.

[0054] It is important to understand that, in combination Figure 4 and Figure 5 Understandably, in this embodiment, the output end of the telescopic drive member 20 is connected to a tool holder 22, and the punching tool 40 is detachably connected to the tool holder 22; the tool holder 22 is provided with a guide post 221, which extends along the telescopic direction of the telescopic drive member 20 and slides through the side support part 311.

[0055] The telescopic drive component 20, such as the output end of a cylinder, is typically a cylindrical structure, while the punching cutter 40 is a thin and wide sheet-like structure. Direct connection between the two is difficult to guarantee in terms of reliability. Therefore, a tool holder 22 is installed at the output end of the telescopic drive component 20, serving as the mounting base for the punching cutter 40, thereby improving the connection reliability of the punching cutter 40. Furthermore, the stability of the telescopic drive component 20 driving the tool holder 22 directly affects the motion accuracy of the punching cutter 40. Therefore, a guide post 221 is provided on the tool holder 22. The sliding cooperation between the guide post 221 and the side support 311 guides the movement of the tool holder 22, thereby improving the motion accuracy of the punching cutter 40 and enhancing the end punching quality of the glass groove 50.

[0056] Considering the ease of disassembly and assembly of the telescopic drive component 20, such as Figure 4 As shown, in this embodiment, the frame 10 is provided with a mounting groove 11, and a drive mounting plate 12 is slidably connected in the mounting groove 11. One side of the frame 10 has a quick-connect pin 13 that passes through the mounting groove 11 and engages with a positioning hole on the drive mounting plate 12. The telescopic drive member 20 is fixedly connected to the drive mounting plate 12, and its output end passes through the drive mounting plate 12 and is connected to the tool holder 22. The top surface of the tool holder 22 is provided with a T-shaped through groove 222 parallel to the extension direction of the mounting groove 11. The output end of the telescopic drive member 20 is provided with a T-shaped clip 200, and the T-shaped clip 200 is slidably connected in the T-shaped through groove 222.

[0057] When it is necessary to disassemble the telescopic drive component 20, simply pull out the quick-release pin 13, and then slide the drive mounting plate 12 out of the mounting slot 11. During the sliding of the drive mounting plate 12, the T-shaped clip 200 slides out of the T-shaped through slot 222 simultaneously. Thus, the output end of the telescopic drive component 20 can be separated from the tool holder 22 at the same time as it is removed from the frame 10. The operation is simple and convenient.

[0058] See Figure 3 In this embodiment, the tool holder 22 is provided with a slot 223 suitable for inserting the punching tool 40, and a pin hole 224 is provided in the tool holder 22 to pass through the slot 223. A pull-out pin 225 is inserted into the pin hole 224. The punching tool 40 is fixed by the pull-out pin 225 passing through the part of the punching tool 40 inserted into the slot 223. This can ensure the connection reliability of the punching tool 40 and facilitate the disassembly and replacement of the punching tool 40.

[0059] For a specific connection structure of the aforementioned side pressure module 321, please refer to Figures 6 to 8The fixed mold 31 is provided with a slide groove 315 on the side of the flat mold opening 300, and the side pressure module 321 is slidably connected to the slide groove 315; the output end of the telescopic drive 20 is fixedly connected to a guide rod 23 along its telescopic direction, the guide rod 23 is connected to the side pressure module 321 and drives the side pressure module 321 to move along the slide groove 315 to press against the glass cloth groove 50.

[0060] The side pressure module 321 is slidably connected in the slide groove 315 and can move closer to or away from the glass groove 50 under the drive of the guide rod 23. This allows the glass groove 50 to easily extend between the moving mold 32 and the fixed mold 31, and also allows the glass groove 50 to be clamped and fixed during the punching process. The structure is simple and compact, and the fixing and punching of the glass groove 50 can be completed in one reciprocating motion of the telescopic drive 20, thereby improving work efficiency.

[0061] Specifically, please refer to Figure 8 The aforementioned side pressure module 321 is provided with a guide hole that extends through the axial direction of the guide rod 23; the guide rod 23 is provided with a first wedge 231 and a second wedge 232 on two opposite side walls extending along the slide groove 315; wherein, when the telescopic drive member 20 drives the guide rod 23 to move downward, the first wedge 231 presses against the wall of the guide hole to drive the side pressure module 321 to press the glass groove 50; when the telescopic drive member 20 drives the guide rod 23 to move upward, the second wedge 232 presses against the other wall of the guide hole to drive the side pressure module 321 to release the glass groove 50.

[0062] When the telescopic drive 20 moves the guide rod 23 downward, the top pressing module 322 moves downward synchronously under its drive and presses against the top of the glass trough 50. The first wedge 231 on the guide rod 23 exerts lateral pressure on the wall of the guide hole, driving the side pressing module 321 to approach and laterally press against the glass trough 50. After the side pressing module 321 presses against the glass trough 50, the part of the guide rod 23 that contacts the guide hole changes from an inclined surface to a straight surface. Therefore, the position of the side pressing module 321 no longer changes as the guide rod 23 continues to move downward. The pressure on the glass lining groove 50 remains unchanged until the punching cutter 40 cuts the glass lining groove 50 along the flat die opening 300. After cutting, the telescopic drive component 20 begins to rise in the direction of the cut. As the guide rod 23 moves upward to the point where the first wedge block 231 disengages from the guide hole, the second wedge block 232 begins to enter the guide hole from bottom to top. As the guide rod 23 continues to move upward, the wedge surface of the second wedge block 232 forms a lateral pressure on the hole wall of the guide hole, thereby driving the side pressure module 321 away from the glass lining groove 50 and facilitating the demolding and extraction of the glass lining groove 50.

[0063] like Figure 8As shown, the upper end of the guide hole wall near the side support 311 is provided with a first inclined guide surface 3211, and the lower end of the guide hole wall away from the side support 311 is provided with a second inclined guide surface 3212. By providing the first inclined guide surface 3211, the first wedge 231 can be transitionally guided, thereby facilitating the smooth insertion of the guide rod 23 with the first wedge 231 into the guide hole. The second inclined guide surface 3212 is provided to transitionally guide the second wedge 232, preventing the second wedge 232 from jamming with the lower end of the guide hole and affecting the smoothness of movement.

[0064] In some embodiments, see Figures 1 to 5 A feed guide seat 70 is connected to the frame 10. The feed guide seat 70 has a guide hole 700, which is used to guide the glass trough 50 between the fixed mold 31 and the moving mold 32. Since the water-cutting ribs or other clamping ribs of the glass trough 50 are in a divergent state under normal conditions, and in order to improve the forming quality of the cut during punching, the port module 30 usually needs to shrink and clamp the glass trough 50. Therefore, the clamping space between the moving mold 32 and the fixed mold 31 does not match the cross-section of the glass trough 50 under normal conditions. The purpose of setting the feed cutter holder 22 here is to gradually form a constraint on the glass trough 50 in the unconstrained state and change it into a contracted state, thereby ensuring that the glass trough 50 can smoothly enter between the moving mold 32 and the fixed mold 31 and improve the feeding smoothness.

[0065] Specifically, such as Figure 5 As shown, the aforementioned feed cutter holder 22 includes a base 71 and a top seat 72. The base 71 is fixedly connected to the frame 10, and the top seat 72 is detachably connected to the base 71. A guide hole 700 is formed between the top seat 72 and the base 71, and the end of the guide hole 700 facing away from the port module 30 is flared. The glass cloth channel 50 enters the guide hole 700 through the flared end of the guide hole 700, and then, under the guidance and constraint of the guide hole 700, gradually forms a cross-sectional shape consistent with the flat die opening 300 and enters between the moving die 32 and the fixed die 31, thereby improving the smoothness of feeding.

[0066] The working process of the automotive glass groove end forming device provided in this embodiment is as follows:

[0067] When the port module 30 is in the initial state of separation between the moving mold 32 and the fixed mold 31, the glass fabric groove 50 is manually or automatically inserted through the guide hole 700 between the moving mold 32 and the fixed mold 31. Then, the telescopic drive 20 drives the cutter holder 22 downward, and the top pressing module 322 gradually presses the glass fabric groove 50 downward against the bottom support 312. At the same time, the side pressing module 321, driven by the guide rod 23 (first wedge 231), gradually presses the glass fabric groove 50 against the side support 311. After the glass fabric groove 50 is fully clamped, as the cutter holder 22 continues to descend, the punching tool 40 cuts the glass fabric groove 50 along the flat die opening 300. After cutting, the telescopic drive 20 drives the cutter holder 22 upward. The top pressing module 322 and the side pressing module 321 remain in a pressing state against the glass lining groove 50. When the punching tool 40 moves upward and disengages from the flat die opening 300 under the drive of the tool holder 22, the limiting part 211 at the top of the slide rod 21 abuts against the tool holder 22. At the same time, the first wedge 231 disengages from the top of the guide hole, and the second wedge 232 begins to enter the guide hole. As the tool holder 22 continues to move upward, the top pressing module 322 begins to slide upward on the guide seat 60 under the drive of the slide rod 21. At the same time, the side pressing module 321 begins to slide away from the side of the glass lining groove 50 under the drive of the second wedge 232. The glass lining groove 50 can be easily demolded and removed when the port module 30 returns to its initial state.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
