Welding apparatus and welding method for glass mold processing

Abstract

This invention relates to the field of glass mold processing technology, specifically to a welding apparatus and method for glass mold processing. The welding apparatus includes a base with a storage hopper and a welding head. The storage hopper stores solder, and its bottom has a discharge port corresponding to and connected to the weld seam. The welding head is located behind the storage hopper along the welding direction, and a welding wire is inserted into it. The welding head is used to weld the weld seam using the welding wire and solder. Two recovery sections are arranged opposite each other on the welding head. These two recovery sections can rotate synchronously around the welding head and are both used to recover solder from the weld seam located behind the welding head. The distances between the suction ends of the two recovery sections and the welding head are unequal. This reduces the dwell time of the recovery sections at the same position in the molten pool, ensuring a faster cooling rate, and allows for two-stage recovery of solder from the same position in the weld seam, improving solder recovery efficiency.

Description

Technical Field

[0001] This invention relates to the field of glass mold processing technology, and in particular to a welding apparatus and welding method for glass mold processing. Background Technology

[0002] As a key forming component in the glass manufacturing process, the processing precision of glass molds directly affects the quality of glass products. Welding is a crucial step in glass mold processing to achieve component assembly and structural reinforcement. Among the welding processes for glass molds, submerged arc welding has become a commonly used welding method due to its significant advantages, including stable welding process, good weld formation quality, effective reduction of welding defects, and the ability to achieve continuous welding to improve processing efficiency. It can meet the basic requirements of glass molds for weld strength and sealing.

[0003] In related technologies, such as Chinese patent CN221134435U, a submerged arc welding device is disclosed, which realizes automatic material recovery and automatic cleaning of weld scale by introducing a material recovery structure and a weld scale cleaning structure.

[0004] However, when the aforementioned submerged arc welding device is used to weld glass molds, the material recovery structure is always located above the weld seam. As a result, during operation, it not only recovers the welding material but also draws in the cold air around the molten pool. The flow of cold air accelerates the cooling of the molten pool. If the cooling rate of the molten pool is too fast, it will cause internal stress and affect the welding strength. At the same time, the material recovery structure only recovers the same position of the weld seam once, which is prone to incomplete recovery and affects the welding material recovery efficiency. Summary of the Invention

[0005] Therefore, it is necessary to provide welding equipment and welding methods for glass mold processing to address the problems of excessively rapid cooling of the molten pool leading to high internal stress and low solder recovery efficiency in the current glass mold welding process.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A welding apparatus for glass mold processing, comprising:

[0008] The base can move in a direction parallel to the weld seam;

[0009] A hopper is mounted on the machine base and configured to store solder. The bottom of the hopper has a discharge port that corresponds to and is connected to the weld seam, allowing the solder to enter the weld seam through the discharge port.

[0010] The welding head is mounted on the machine base and located behind the storage hopper along the weld direction; welding wire is inserted into the welding head, and the welding head is configured to weld the weld using welding wire and welding material;

[0011] Two recovery units are positioned opposite each other on the welding head and can rotate synchronously around the welding head. Both units are configured to recover the solder at the weld seam located behind the welding head. The distances between the suction ends of the two recovery units and the welding head are unequal.

[0012] Furthermore, a support sleeve is rotatably fitted onto the welding head; the support sleeve is provided with two connecting pipes, which are arranged opposite each other. The connecting pipes are arc-shaped, and each connecting pipe has two first connecting ports. The two first connecting ports on the same connecting pipe are arranged circumferentially, and the first connecting ports on different connecting pipes are arranged along the extension direction of the connecting pipe; a middle part is sleeved on both connecting pipes. The middle part can slide along the extension direction of the connecting pipe and can communicate with the recovery part through the two first connecting ports on the same connecting pipe; the welding device for glass mold processing also includes an adjustment component, which is configured to drive the middle part to slide along the connecting pipe through the recovery part, so as to disconnect the communication between the recovery part and the middle part located between the storage hopper and the welding head when the recovery part is located between the storage hopper and the welding head.

[0013] Furthermore, the positioning assembly includes two magnets, one of which is mounted on the base and located between the welding head and the storage hopper, and the other magnet is mounted on the recovery section further away from the welding head at the suction end, and the two magnets can form a magnetic connection.

[0014] Furthermore, the welding apparatus for glass mold processing also includes a drive element configured to provide a driving force for the rotation of the support sleeve.

[0015] Furthermore, the driving component is a hollow motor.

[0016] Furthermore, the welding device for glass mold processing also includes a suction component, the suction end of which is connected to the middle part and configured to generate negative pressure.

[0017] Furthermore, the suction component is an air pump.

[0018] Furthermore, the welding apparatus for glass mold processing also includes a moving part configured to provide a driving force for moving the base.

[0019] Furthermore, the moving part is an electric trolley, and the base is mounted on the electric trolley.

[0020] The present invention also provides a welding method for glass mold processing, employing a welding apparatus for glass mold processing, and the welding method for glass mold processing includes the following steps:

[0021] S1. Place the solder into the storage hopper;

[0022] S2. Drive the machine base to move in a direction parallel to the weld seam, and the welding material enters the weld seam through the discharge port under its own weight;

[0023] S3. Start the welding head. The welding head welds the seam using welding wire and welding material.

[0024] S4. Drive the recovery unit to rotate around the welding head, and at the same time, the recovery unit recovers the welding material located at the weld seam behind the welding head.

[0025] The beneficial effects of this invention are:

[0026] This invention relates to a welding apparatus and welding method for glass mold processing. By setting up two recovery sections and utilizing the rotation and recovery characteristics of the recovery sections, it can effectively reduce the dwell time of the recovery sections at the same position in the molten pool, which helps to reduce the cold air flow rate near the molten pool, ensure that the cooling rate of the molten pool is not too fast, and thus ensure that there is no large stress inside, which helps to improve the welding strength. It can also recover the solder at the same position of the weld twice, which helps to improve the recovery efficiency of the solder.

[0027] Furthermore, by setting up a connecting pipe and an intermediate section, and setting up an adjustment component that works with both, the intermediate section can be driven to slide along the connecting pipe by the recovery section. This allows the recovery section, which is farther from the welding head at the suction end, to scrape the weld material at the weld seam between the storage hopper and the welding head, making the weld material distribution at the weld seam between the storage hopper and the welding head more uniform and improving the welding quality. It also allows the recovery section, which is farther from the welding head at the suction end, to scrape off the welding slag left after welding, reducing the trouble of subsequent cleaning.

[0045] The following reference Figures 1 to 6 The present invention describes a welding apparatus for glass mold processing, which is particularly suitable for welding glass molds, and of course, it is also suitable for welding other workpieces.

[0046] Specifically, the welding device for glass mold processing includes a base 1; a storage hopper 2 is provided on the base 1, which is located above the weld seam during use and is used to store welding material. The bottom of the storage hopper 2 has a discharge port 201, which corresponds to and communicates with the weld seam, facilitating the welding material to enter the weld seam under its own weight; a welding head 3 is also provided on the base 1, which is located above the weld seam during use and behind the storage hopper 2 along the weld seam direction, ensuring that the welding material fills the weld seam first, and then the welding head 3 embeds the welding material, facilitating subsequent submerged arc welding. The process involves a welding head 3 with a welding wire inserted inside, used to weld the weld seam using the welding wire and solder. A solder recovery structure is also provided on the base 1. During use, the solder recovery structure is located above the weld seam and behind the welding head 3 along the weld seam direction, and can generate negative pressure. While the welding head 3 is welding the weld seam, the solder recovery structure can recover any remaining solder at the weld seam. The base 1 can move in a direction parallel to the weld seam, allowing the storage hopper 2, welding head 3, and solder recovery structure to move synchronously in a direction parallel to the weld seam, facilitating continuous operation of solder input-welding-solder recovery.

[0047] To facilitate the provision of driving force for the base 1 to move in a direction parallel to the weld, the welding device for glass mold processing is configured to also include a moving part, which can be an electric trolley 7. The base 1 is fixedly mounted on the top of the electric trolley 7 so that it can move synchronously with the electric trolley 7 in a direction parallel to the weld.

[0048] During the welding process on the glass mold, the solder is first placed into the storage hopper 2; then the electric trolley 7 is started, which drives the machine base 1 to move in a direction parallel to the weld. When the machine base 1 moves, it simultaneously drives the storage hopper 2, the welding head 3, and the solder recovery structure to move in a direction parallel to the weld until the solder recovery structure moves from the rear end to the front end of the weld. When the storage hopper 2 moves, the solder enters the weld through the discharge port 201 under its own weight. When the welding head 3 moves, it is first embedded in the solder, and then the weld is welded by the welding wire and the solder. When the solder recovery structure moves, the remaining solder at the weld is recovered simultaneously.

[0049] While the above process enables welding of the weld seams on the glass mold, the solder recovery structure not only recovers the solder during operation but also simultaneously draws in cold air from the surrounding environment of the molten pool. This rapid airflow accelerates the cooling of the molten pool. If the cooling rate is too fast, the temperature gradient within the molten pool metal increases dramatically, leading to significant differences in shrinkage rates across different regions. This, in turn, generates substantial internal stress within the molten pool and at the junction of the molten pool and the base material. If this internal stress cannot be effectively eliminated through subsequent processing, it directly reduces the mechanical properties of the weld, causing a decrease in key indicators such as tensile strength and impact toughness. In severe cases, it may even generate microcracks inside or on the surface of the weld, posing a safety hazard for the long-term use of the glass mold. During operation, the glass mold must withstand certain temperature changes and mechanical loads; weld seams with internal stress are highly susceptible to cracking under these loads, ultimately affecting the service life of the glass mold and the forming accuracy of the glass products.

[0050] At the same time, because the solder recovery structure only recovers the solder at the same location of the weld once, it is easy to cause incomplete solder recovery, which affects the solder recovery efficiency.

[0051] Based on this, in the welding device for glass mold processing provided in this embodiment of the invention, a support sleeve 301 is fitted onto the welding head 3. The support sleeve 301 is a tubular structure, vertically arranged, and capable of rotating around its own axis. Two connecting pipes 302 are provided on the support sleeve 301, respectively located on the front and rear side walls of the support sleeve 301, and both are vertically arranged. The connecting pipes 302 are arc-shaped, and their openings face each other to form a near-circular structure. The upper and lower ends are sealed on the support sleeve 301; the left and rear walls of the connecting pipe 302 located on the rear side are provided with first connecting ports, and the two first connecting ports are located in the middle of the arc of the connecting pipe 302, arranged in a circumferential manner; the left and front walls of the connecting pipe 302 located on the front side are provided with first connecting ports, and the two first connecting ports are located below the middle of the arc of the connecting pipe 302, arranged in a circumferential manner, so that the first connecting ports on different connecting pipes 302 are arranged along the extension direction of the connecting pipe 302.

[0052] Two connecting pipes 302 are connected to a common middle part 5. The base of the middle part 5 is a first connecting pipe 501, which extends horizontally to the left. The right end of the first connecting pipe 501 is connected to a second connecting pipe 502, which has a U-shaped structure and its opening is horizontally facing to the right. The first connecting pipe 501 and the second connecting pipe 502 together form a three-way structure. A connecting sleeve 503 is vertically installed at each of the two openings of the second connecting pipe 502. The connecting sleeve 503 has an arc-shaped tubular structure, and the two connecting sleeves 503 are slidably fitted onto the two connecting pipes 302 respectively. Two second connecting ports 5031 are opened on the peripheral sidewall of each connecting sleeve 503. The two second connecting ports 5031 on the same connecting sleeve 503 are arranged circumferentially and can communicate with the two first connecting ports on the same connecting pipe 302.

[0053] Each connecting sleeve 503 is provided with a recycling section 4. The base of the recycling section 4 is a recycling tube 401, which has an L-shaped structure. The horizontal section of the recycling tube 401 located at the rear is horizontally positioned and extends rearward, and can communicate with the second communication port 5031 on the rear side wall of the connecting sleeve 503 located at the rear. The vertical section of the recycling tube 401 located at the rear is vertically positioned and extends downward, and its end is fixedly sleeved with a recycling cover 402. The horizontal section of the recycling tube 401 located at the front is horizontally positioned and extends forward, and can communicate with the second communication port 5031 on the front side wall of the connecting sleeve 503 located at the front. The vertical section of the recycling tube 401 located at the front is vertically positioned and extends downward, and its end is fixedly sleeved with a recycling cover 402. The straight section is set vertically and extends downward, with a recovery cover 402 fixedly sleeved at the end; and the length of the horizontal section of the recovery pipe 401 located on the rear side is less than the length of the horizontal section of the recovery pipe 401 located on the front side, ensuring that the distance between the suction end of the two recovery sections 4 and the welding head 3 is not equal. This ensures that when the recovery section 4 with the shorter horizontal section performs the first recovery of the remaining solder on the weld, as the base 1 moves and the middle section 5 rotates, when the recovery section 4 with the longer horizontal section performs the second recovery of the remaining solder on the weld, the recovery position can remain unchanged, thus facilitating the two recoverys of the solder at the same position on the weld, which helps to improve the recovery efficiency of the solder.

[0054] The welding device for glass mold processing is configured to also include an adjustment assembly 6, which includes two magnets. One magnet is a magnet 601, which is mounted on the base 1 and located between the welding head 3 and the storage hopper 2. The other magnet is a steel plate 602, which is mounted on the top of the horizontal section of the recovery pipe 401 located at the rear. A magnetic connection can be formed between the magnet 601 and the steel plate 602.

[0055] To facilitate the provision of driving force for the rotation of the support sleeve 301, the welding device for glass mold processing is configured to also include a driving component. The driving component can be a hollow motor, and the motor shaft of the hollow motor and the support sleeve 301 have the same structure.

[0056] To facilitate the driving force for the recovery unit 4 to recover the solder, the welding device for glass mold processing is configured to also include a suction component, which can be configured as an air pump. The suction end of the air pump is connected to the first connecting pipe 501 to facilitate the generation of negative pressure to suction the remaining solder on the weld.

[0057] Initially, such as Figure 4 As shown, magnet 601 and steel plate 602 are attracted together, and storage hopper 2, welding head 3 and two recycling sections 4 are located on the same straight line; the recycling section 4 with shorter horizontal section is located behind welding head 3 and is connected through first connecting port, second connecting port 5031 and middle section 5.

[0058] During the welding process on the glass mold, the welding material is first placed into the storage hopper 2; then the electric trolley 7, hollow motor and air pump are started. The electric trolley 7 drives the machine base 1 to move in a direction parallel to the weld. When the machine base 1 moves, it simultaneously drives the storage hopper 2, welding head 3, recovery part 4, intermediate part 5 and adjustment component 6 to move in a direction parallel to the weld. When the storage hopper 2 moves, the welding material enters the weld through the discharge port 201 under its own weight. When the welding head 3 moves, it is first embedded in the welding material, and then the weld is welded by welding wire and welding material.

[0059] An air pump connects to the intermediate section 5 and the shorter horizontal section of the recovery section 4 to recover the remaining solder at the weld joint. A hollow motor drives the support sleeve 301 to rotate. As the support sleeve 301 rotates, it simultaneously drives the two connecting pipes 302 to rotate around it. The rotation of the connecting pipes 302 also simultaneously drives the recovery section 4 and the intermediate section 5 to rotate around the support sleeve 301, causing the magnet 601 and the steel plate 602 to gradually shift out of alignment. When the longer horizontal section of the recovery section 4 rotates, it simultaneously scrapes the solder at the weld joint between the storage hopper 2 and the welding head 3 through its recovery cover 402, thus distributing the solder at the weld joint between the storage hopper 2 and the welding head 3. The more uniform distribution of the material helps improve welding quality. When the longer horizontal section of the recovery part 4 rotates at a certain angle, the magnet 601 and the steel plate 602 are completely misaligned. Then, under the action of gravity, the longer horizontal section of the recovery part 4 moves downward to contact the glass mold, simultaneously driving the middle part 5 to slide along the connecting pipe 302. At the same time, the shorter horizontal section of the recovery part 4 is lifted, causing the shorter horizontal section of the recovery part 4 and the middle part 5 to disconnect, while the longer horizontal section of the recovery part 4 and the middle part 5 become connected.

[0060] As the recovery section 4 rotates, the longer horizontal section of the recovery section 4 gradually rotates to the rear of the welding head 3. When the storage hopper 2, the welding head 3, and the two recovery sections 4 are once again aligned on the same straight line, as... Figure 5 As shown, the longer horizontal section of the recovery unit 4 is located behind the welding head 3, while the shorter horizontal section of the recovery unit 4 is located between the storage hopper 2 and the welding head 3. In this process, the longer horizontal section of the recovery unit 4 can scrape off the welding slag left after welding, reducing the hassle of subsequent cleaning, and can also perform secondary recovery of the solder at the same location on the weld, thus improving the solder recovery efficiency.

[0061] As the recovery section 4 continues to rotate, the longer horizontal section of the recovery section 4 gradually rotates to the space between the storage hopper 2 and the welding head 3. Then, under the magnetic attraction of the magnet 601, the steel plate 602 drives the longer horizontal section of the recovery section 4 to rotate upward until it is attracted to the magnet 601. Simultaneously, it drives the middle section 5 to slide along the connecting pipe 302, while pressing down the shorter horizontal section of the recovery section 4, thus connecting the shorter horizontal section of the recovery section 4 with the middle section 5 and disconnecting the longer horizontal section of the recovery section 4 from the middle section 5. At this time, the shorter horizontal section of the recovery section 4 recovers the remaining welding material at the next position of the weld.

[0062] Repeat the above process to achieve continuous operation of solder input, welding, and solder recycling.

[0063] In other embodiments, both magnetic components can be configured as magnet 601.

[0064] Another embodiment of the present invention provides a welding method for glass mold processing, employing a welding apparatus for glass mold processing, and the welding method for glass mold processing includes the following steps:

[0065] S1. Place the solder into the storage hopper 2;

[0066] S2. Drive the machine base 1 to move in a direction parallel to the weld seam, and the welding material enters the weld seam through the discharge port 201 under its own weight;

[0067] Specifically, the electric trolley 7 is started, and the electric trolley 7 drives the machine base 1 to move in a direction parallel to the weld.

[0068] S3. Start welding head 3. Welding head 3 welds the weld seam using welding wire and welding material;

[0069] S4. Drive the recovery unit 4 to rotate around the welding head 3, and at the same time, the recovery unit 4 recovers the welding material at the weld seam located behind the welding head 3.

[0070] Specifically, the hollow motor is started, and the hollow motor drives the recovery section 4 to rotate around the welding head 3 through the support sleeve 301, connecting pipe 302 and intermediate part 5. Under the action of the adjustment component 6, the recovery section 4 with a shorter horizontal section recovers the remaining solder on the weld seam once, and then the recovery section 4 with a longer horizontal section recovers the remaining solder at the same position of the weld seam a second time, which helps to improve the recovery efficiency of the solder. During the rotation of the recovery section 4 with a longer horizontal section, the recovery section 4 can not only scrape the solder at the weld seam between the storage hopper 2 and the welding head 3 through the recovery cover 402 on it, so that the solder at the weld seam between the storage hopper 2 and the welding head 3 is more evenly distributed, which helps to improve the welding quality, but also scrapes off the welding slag left after welding, which helps to reduce the trouble of subsequent cleaning.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above embodiments are merely illustrative of several implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
