Description

Technical Field

[0001] The present invention relates to the technical field of mold production, and specifically to a welding device and a processing method for mold production with automatic workpiece replacement. Background Technique

[0002] A mold is a model tool used to produce products with specific shape and size requirements. It is a tool for processes such as forming, separating, forging, and extruding in industrial production. By changing the physical state of materials, it realizes the processing of the outer shape of articles and is widely used in industrial fields such as automobiles, electrical appliances, and communications.

[0003] When repairing and producing molds, a welding device is needed to perform plasma welding on the mold gaps. Existing mold welding devices all individually place the mold on the device for repair welding. After welding is completed, it is taken off and a new mold is placed into the device for processing. It is not convenient to automatically replace the molds to be processed, which affects the processing speed of the molds, reduces work efficiency, and increases the workload of the staff. For this reason, we propose a welding device and a processing method for mold production with automatic workpiece replacement.

[0004] Combined with the above problems, we will find that existing welding devices on the market are very difficult to avoid the above-mentioned problems simultaneously when in use.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: Please refer to Figures 1 - 10 , the present invention provides a technical solution: A welding device and processing method for mold production with automatic workpiece replacement, including a device body 1. The device body 1 includes a processing box 103. A control terminal 102 is fixedly installed on the front side of the processing box 103. A welding assembly 104 is installed in the inner cavity of the processing box 103. A replacement mechanism 2 is arranged in the inner cavity of the processing box 103. The bottom of the processing box 103 is fixedly connected with a support base 101;

[0040] The replacement mechanism 2 includes a clamping unit 21, and the clamping unit 21 is arranged in the inner cavity of the processing box 103;

[0041] The replacement mechanism further includes a pushing unit 22. The pushing unit 22 is arranged on one side of the clamping unit 21, and the clamping unit 21 and the pushing unit 22 are used in cooperation;

[0042] The replacement mechanism 2 includes a clamping unit 21, and the clamping unit 21 is arranged in the inner cavity of the processing box 103;

[0043] The replacement mechanism further includes a pushing unit 22, which is arranged on one side of the clamping unit 21, and the clamping unit 21 is used in cooperation with the pushing unit 22.

[0044] As a further limitation of the present invention, the clamping unit 21 includes a support plate 2106, which is arranged in the inner cavity of the processing box body 103. Two short rods 2108 are rotatably connected to both sides of the support plate 2106 through rotating shafts. The bottom end of the short rod 2108 is rotatably connected to a first connecting rod 2109 through a rotating shaft. One end of the first connecting rod 2109 is rotatably connected to a clamping rod 2113 through a rotating shaft, and the other end of the first connecting rod 2109 is rotatably connected to a U-shaped plate 2103 through a rotating shaft. A connecting column 2111 is arranged between the two U-shaped plates 2103, and the connecting column 2111 is fixedly connected to the surface of the U-shaped plate 2103. A second connecting rod 2110 is rotatably connected to the inner cavity of the U-shaped plate 2103 through a rotating shaft, and one end of the second connecting rod 2110 is rotatably connected to the surface of the clamping rod 2113 through a rotating shaft. Two hydraulic cylinders 2105 are fixedly connected to the top of the support plate 2106. The telescopic end of the hydraulic cylinder 2105 penetrates through the support plate 2106 and is fixedly connected to a pushing plate 2114. One end of the pushing plate 2114 is fixedly sleeved on the surface of the connecting column 2111. By setting the connecting column 2111, when the pushing plate 2114 moves, the first connecting rod 2109 and the second connecting rod 2110 can rotate, so that the clamping rod 2113 can drive the adaptive rubber pad 2112 to clamp and fix the mold, and the mold to be processed can be clamped and placed at the processing position for plasma welding processing, improving the convenience of replacing workpiece processing and preventing movement during welding.

[0045] A support frame 2101 is fixedly connected to the inner cavity of the processing box body 103. A first motor 2107 is fixedly connected to one side of the support frame 2101. The output end of the first motor 2107 penetrates into the inner cavity of the support frame 2101 and is fixedly connected to a threaded rod 2102. One end of the threaded rod 2102 is rotatably connected to the inner wall of the support frame 2101 through a bearing. By setting the threaded rod 2102, the moving plate 2104 can be moved, so that the clamping rod 2113 can move left and right to clamp and replace the molds on both sides, improving the convenience of mold processing.

[0046] A moving plate 2104 is movably sleeved on the surface of the support frame 2101. One end of the moving plate 2104 is threadedly sleeved on the surface of the threaded rod 2102, and the top of the support plate 2106 is fixedly connected to the surface of the moving plate 2104.

[0047] The pushing unit 22 includes an L-shaped rod 2202. One end of the L-shaped rod 2202 is fixedly connected to the surface of the moving plate 2104. A pushing block 2201 is fixedly connected to one end of the L-shaped rod 2202. A vertical plate 2205 is fixedly connected to the inner cavity of the processing box body 103. A pushing rod 2203 is slidably installed on one side of the vertical plate 2205. One end of the pushing rod 2203 penetrates to one side of the vertical plate 2205. A return spring 2204 is movably sleeved on the surface of the pushing rod 2203. Two ends of the return spring 2204 are respectively fixedly connected to one side of the vertical plate 2205 and the surface of the pushing rod 2203. By providing the pushing block 2201, the pushing rod 2203 can be extruded, so that the processed mold can be pushed, and it can be moved to the storage conveyor 4 for storage, thereby facilitating the placement and processing of a new mold, and improving the efficiency of mold replacement processing.

[0048] By setting the combined use of the clamping unit 21 and the pushing unit 22, the purpose of automatically replacing workpieces can be achieved. After the mold is processed by plasma welding, the processed mold can be automatically pushed out, and at the same time, the mold to be processed can be placed at the processing position for clamping, which facilitates the processing of the mold, improves the processing efficiency of the mold, thus ensuring the production efficiency, and at the same time reducing the workload of the staff.

[0049] The specific implementation of this embodiment is as follows: When processing the mold, the telescopic end of one of the hydraulic cylinders 2105 retracts, driving the push plate 2114 thereon to move upward, causing the connecting column 2111 and the U-shaped plate 2103 thereon to move upward, enabling the first connecting rod 2109 and the second connecting rod 2110 thereon to rotate. At the same time, the short rod 2108 rotates following the first connecting rod 2109, allowing the clamping rod 2113 to move closer to the mold, so that the adaptive rubber pad 2112 can contact the surface of the mold, thereby clamping the mold. After clamping is completed, the first motor 2107 drives the threaded rod 2102 to rotate, causing the moving plate 2104 to move and drive the support plate 2106 to move, so that the mold can be clamped and placed on the anti-slip placement plate 6. Through the programming of the control terminal 102, the welding assembly 104 can, through visual search, view the gaps on the surface of the mold, and move the welding assembly 104 to the position of the mold gap for plasma welding processing. After the mold is placed on the anti-slip placement plate 6, the clamping rod 2113 on the other side also moves to the feeding conveyor 5 on the other side. After processing is completed, the shortened hydraulic cylinder 2105 extends and resets, causing the clamping rod 2113 to move away from the processed mold, so as not to clamp the processed mold. The other hydraulic cylinder 2105 shortens, causing the push plate 2114 thereon to move upward, causing the connecting column 2111 and the U-shaped plate 2103 thereon to rise. Under the action of the first connecting rod 2109 and the second connecting rod 2110, the clamping rod 2113 clamps the mold to be processed. After clamping is completed, again through the first motor 2107 and the threaded rod 2102, the moving plate 2104 drives the support plate 2106 to move again, so that the clamping rod 2113 clamps the un-welded mold and moves it above the anti-slip placement plate 6. At the same time, the L-shaped rod 2202 moves following the moving plate 2104. When the two pairs of clamping rods 2113 move to both sides of the processed mold, the pushing block 2201 can squeeze the pushing rod 2203, causing the return spring 2204 to be squeezed, enabling the pushing rod 2203 to push the processed mold, and it can be pushed onto the storage conveyor 4 for storage. The moving plate 2104 continues to move, allowing the mold to be processed to be placed at the processing position for convenient processing. The above operations can be repeated to automatically replace the workpiece, improving the efficiency of mold processing.

[0050] Embodiment 2: Please refer to Figures 1 - 10 , the present invention provides a technical solution: A welding device for mold production with automatic workpiece replacement, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0051] As a further limitation of the present invention, there are two material sorting mechanisms 3 arranged in the inner cavity of the processing box 103;

[0052] The blanking mechanism 3 includes a blanking housing 301. The bottom of the blanking housing 301 is fixedly connected to the inner cavity of the processing box body 103. A second motor 308 is fixedly connected to the bottom of the blanking housing 301. The output end of the second motor 308 penetrates into the inner cavity of the blanking housing 301 and is fixedly connected to a rotating housing 307. The bottom end of the rotating housing 307 is rotationally connected to the inner cavity of the blanking housing 301 through a bearing. A second spring 310 is fixedly connected to the inner cavity of the rotating housing 307. The top end of the second spring 310 is fixedly connected to a vibration column 311. The top end of the vibration column 311 penetrates through the top of the rotating housing 307 and is fixedly connected to a conical guiding blanking plate 302. By setting the conical guiding blanking plate 302, after the mold is placed in the blanking housing 301, the mold can slide downwards in all directions, so that it can slide into the feeding conveyor 5 through the guiding plate 303 for automatic arrangement and transportation, which is convenient for subsequent replacement and processing of the mold and improves the convenience of mold processing.

[0053] A first spring 304 is movably sleeved on the surface of the vibration column 311. The two ends of the first spring 304 are respectively fixedly connected to the bottom of the conical guiding blanking plate 302 and the surface of the rotating housing 307. A fixing plate 312 is fixedly connected to the inner cavity of the blanking housing 301. One end of the fixing plate 312 is rotationally connected to a rotating rod 305 through a bearing. A cam 306 is fixedly sleeved on one end of the rotating rod 305. By setting the cam 306, the conical guiding blanking plate 302 can be slapped, so that the conical guiding blanking plate 302 can vibrate, so that the placed mold can slide downwards better in all directions, so as to carry out arrangement and blanking, which is convenient for subsequent processing of the mold.

[0054] One end of the rotating rod 305 penetrates to one side of the fixing plate 312. Bevel gears 309 are fixedly sleeved on the surfaces of the rotating rod 305 and the rotating housing 307. The two bevel gears 309 are meshed with each other. A guiding plate 303 is fixedly connected to one side of the blanking housing 301. A feeding conveyor 5 is fixedly installed at one end of the guiding plate 303. The bottom of the feeding conveyor 5 is fixedly connected to the inner cavity of the processing box body 103.

[0055] An anti-slip placing plate 6 is fixedly connected to the inner cavity of the processing box body 103. A storage conveyor 4 is fixedly installed on one side of the anti-slip placing plate 6. The bottom of the storage conveyor 4 is fixedly connected to the inner cavity of the processing box body 103. Feeding box doors 105 are rotatably installed on the left and right sides of the processing box body 103 through rotating shafts. By setting the feeding box doors 105, the two sides of the processing box body 103 can be sealed, and at the same time, it is also convenient to put the mold into the blanking housing 301 for blanking and transportation, so as to facilitate the automatic replacement and processing of the mold and improve the efficiency of mold processing.

[0056] By setting up the blanking mechanism 3, the purpose of automatic blanking can be achieved, enabling multiple molds placed in the device to be automatically arranged, facilitating subsequent mold replacement and processing, thus ensuring the convenience of mold processing, increasing the speed of mold processing, and allowing for faster production and processing.

[0057] The specific implementation of this embodiment is as follows: Open the blanking box door 105, and place multiple molds to be processed on the conical guiding blanking plate 302. Drive the rotating shell 307 to rotate through the second motor 308, and the vibrating columns 311 rotate accordingly, thereby driving the conical guiding blanking plate 302 to rotate, enabling the molds placed thereon to rotate within the blanking shell 301. At the same time, under the action of the bevel gear 309, the rotating rod 305 drives the cam 306 to rotate, thereby rotating and patting the conical guiding blanking plate 302, causing the first spring 304 and the second spring 310 to contract, enabling the conical guiding blanking plate 302 to vibrate. Since the conical guiding blanking plate 302 is higher in the middle and lower around the perimeter, the molds on the conical guiding blanking plate 302 can slide better towards the periphery. The molds rotate on the conical guiding blanking plate 302 and when they rotate to one side of the guiding plate 303, they can slide onto the guiding plate 303. Through the guiding of the guiding plate 303, they can fall onto the feeding conveyor 5. Start the feeding conveyor 5 to convey the un-welded molds, and convey them between a pair of clamping rods 2113 for clamping. After the molds welded on the anti-slip placement plate 6 are processed, the un-welded molds can be clamped and then clamped onto the anti-slip placement plate 6 for further processing, thus facilitating mold replacement and processing. In addition, during use, according to the welding speed of the molds, both the second motor 308 and the feeding conveyor 5 are adjusted to an intermittent operation mode through the control terminal 102 to avoid continuous feeding causing mold stacking and blockage, thereby facilitating automatic mold replacement and processing.

[0058] A method for using a welding device for mold production with automatic workpiece replacement includes the following steps:

[0059] S1: Place the molds to be welded into the blanking shell 301. Rotate the conical guiding blanking plate 302 through the second motor 308, and at the same time, use the bevel gear 309 to make the cam 306 pat the conical guiding blanking plate 302 to vibrate it so that the molds can slide towards the periphery and fall into the guiding plate 303. Through the guiding of the guiding plate 303, they fall onto the feeding conveyor 5, thereby achieving automatic blanking.

[0060] S2: Convey the mold to one side through the feeding conveyor 5 so that it is conveyed between the clamping rods 2113. Shorten the hydraulic cylinder 2105 to move the connecting column 2111 upward, enabling the clamping rods 2113 to drive the adaptive rubber pads 2112 to move and clamp the mold. Then, use the first motor 2107 and the threaded rod 2102 to move the moving plate 2104, thereby moving the support plate 2106 and moving the clamped mold to the anti-slip placement plate 6 for plasma welding processing of the mold.

[0061] S3: When clamping the mold to the anti-slip placement plate 6 for welding, the clamping rod 2113 on the other side can move onto the feeding conveyor 5. After the welded mold is completed, the clamping rod 2113 can clamp the mold to be processed again, and then clamp it to the anti-slip placement plate 6 for plasma welding processing, thus automatically replacing the workpiece for welding.

[0062] S4: When clamping another mold to be processed onto the anti-slip placement plate 6, the L-shaped rod 2202 moves with the support plate 2106, enabling the pushing block 2201 to move to the rear side of the pushing rod 2203, thereby squeezing the pushing rod 2203 and allowing the pushing rod 2203 to push the welded mold onto the storage conveyor 4, thus realizing the automatic pushing out of the welded workpiece.

[0063] S5: When pushing the welded mold onto the storage conveyor 4, the storage conveyor 4 can convey the mold, enabling the storage conveyor 4 to store multiple molds. After storing multiple molds, they can be taken out for the next storage.

[0064] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
