Description

Technical Field

[0001] The invention relates to the technical field of curling production, and in particular to a precision curling production system. Background Art

[0002] Rolling is a metalworking method used to bend sheet metal into a nearly closed cylindrical shape. This process is widely used to manufacture round or cylindrical metal tubes or ring parts, such as the cylindrical shell of a car cigarette lighter.

[0003] In the continuous stamping process of the cigarette lighter shell, in order to reduce blade adhesion, lower mold temperature, reduce end face wear, and improve the accuracy of processing dimensions, stamping oil is usually used as a lubricant for the mold. This oil not only plays a lubricating role, but also has heat dissipation, cooling and extreme pressure properties to ensure the smooth progress of the stamping process and the long-term use of the mold. Therefore, stamping oil will adhere to the surface of the stamped parts after stamping, which not only affects the appearance quality of the product, but also may have potential impact on subsequent use. Based on this, the stamping oil on the stamped parts needs to be cleaned. At present, the stamped parts that have been stamped need to be transported to the cleaning process through a conveyor line, and the products after production need to be manually sorted and stored, which makes the precision curling production system occupy a large area, the process is cumbersome, and consumes human resources.

DETAILED DESCRIPTION

[0079] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0080] like Figure 12-14 As shown, the precision rolled product structure includes a rolled body 10, the outer wall of the rolled body 10 is processed inwardly with a plurality of barbs 11, and the bottom of the rolled body 10 is processed with a plurality of tentacles 12, and the connection points at both ends of the rolled body 10 are bent inwardly to form a clamping point 13.

[0081] like Figure 1-11As shown, the present invention provides a production system for producing the above-mentioned precision rolled products, including a main frame 1, a stamping die 2 arranged on the main frame 1, a discharge rack 3 arranged on one side of the main frame 1, a cleaning and drying section 4 arranged on the top of the main frame 1, and a sorting section 5 arranged on the front side of the main frame 1; the discharge rack 3 conveys the material strip to the stamping die 2 to stamp out a precision rolled product, and the product is cleaned and dried by the cleaning and drying section 4 and then conveyed to the sorting section 5 for sorting.

[0082] Specifically, Figure 2 and 3 As shown, the stamping die 2 includes an upper die base 201 , an upper die 202 , a lower die 203 and a lower die base 204 from top to bottom, and one end of the housing 41 of the cleaning and drying part 4 away from the finishing part 5 is fixed on the lower die base 204 .

[0083] The stamping die 2 is provided with multiple sets of positioning components, which include correspondingly arranged infrared transmitters 7 and infrared receivers 9. An upper embedding groove 6 is provided at the bottom of the upper die base 201, and each infrared transmitter 7 is fixed in the upper embedding groove 6. A plurality of lower embedding grooves 8 are provided at the top of the upper die base 201, and each infrared receiver 9 is fixed in the lower embedding groove 8.

[0084] like Fig.15 As shown, the material strip of the precision rolled product is unloaded onto the stamping die 2 via the unloading rack 3, and the head end and both sides of the material strip are used as positioning. A positioning connection area 14 is punched out at the head end of the material strip, and positioning holes 15 are punched out on both sides of the material strip, and the processing area is located between every two opposite positioning holes 15; when the material strip is running so that the positioning holes 15 are directly above the lower embedded groove 8, the material strip does not block the infrared rays of the infrared transmitter 7 from being received by the infrared receiver 9. At this time, the control system of the present invention (the control system adopts the existing control structure, which is not described here) stops the operation of the material strip and controls the stamping die 2 to accurately process the material strip to improve the processing accuracy.

[0085] After the product is stamped, stamping oil will adhere to its surface. In order to clean the stamping oil, a cleaning and drying part 4 is provided. Specifically, Figure 3 As shown, the cleaning and drying section 4 is arranged at the blanking port of the stamping die 2, and a guide groove 205 is fixed at the blanking port at the bottom of the lower die 203. A feed port 411 is provided at the top of the outer shell 41 of the cleaning and drying section 4, which is located directly below the guide groove 205. The feed port 411 is arranged at the bottom of the blanking port of the lower die 203, and the stamped product falls into the cleaning and drying section 4 along the guide groove 205 and the feed port 411.

[0086] like Figure 4-9As shown, the cleaning and drying section 4 includes a shell 41 fixed to the top of the main frame 1, a cleaning chamber 42 and a drying chamber 43 are provided in the shell 41, a drain pipe 49 is fixed to the bottom of the side of the shell 41 away from the finishing section 5, the cleaning chamber 42 and the drying chamber 43 are provided with the same conveying assembly 44, and a plurality of tooling assemblies 45 are provided on the conveying assembly 44, and the precision rolled products are placed on the tooling assemblies 45 for integrated cleaning, drying and conveying operations;

[0087] The portion of the conveying component 44 located in the cleaning chamber 42 is configured as an inclined section so that liquid will not accumulate on the inclined section of the conveying component 44. The portion of the conveying component 44 located in the drying chamber 43 is configured as a horizontal section, and the horizontal section of the conveying component 44 extends out of the front side of the outer shell 41. Two groups of opposing photoelectric sensors 48 are provided on the right side plate 441 and the left side frame 442, and the two groups of opposing photoelectric sensors 48 are respectively provided at both ends of the inclined section of the conveying component 44.

[0088] like Figure 7-9 As shown, the conveying assembly 44 includes a right side plate 441 and a left side frame 442 fixed inside the shell 41, and at least two rollers 443 are arranged between the right side plate 441 and the left side frame 442 (the number of rollers 443 can be selected according to actual conditions to improve the stability of conveying), and the rollers 443 are rotatably connected to the right side plate 441 through a rotating shaft, and the rollers 443 are arranged outside the left side frame 442, and a conveyor belt 444 is sleeved on the outer side of the rollers 443, and one of the rollers 443 is driven to rotate by a motor. The roller 443 of the present invention is a single-sided roller (that is, a roller supported on only one side), which can be suitable for conveying small objects such as cigarette lighter shells.

[0089] The tooling assembly 45 includes a hollow plate 451 disposed on the conveyor belt 444 and moving with the conveyor belt 444. Stoppers 457 are fixed to both sides of the top of each hollow plate 451. A pipe 452 is installed on the side of the hollow plate 451 away from the conveyor belt 444 through a sealed bearing, and an electric valve is fixed on the pipe 452. A hollow disk 453 is fixed to the end of the pipe 452 away from the hollow plate 451. A hollow column 454 is fixed to the end of the hollow disk 453 away from the pipe 452. The hollow plate 451, the pipe 452, the hollow disk 453 and the hollow column 454 are connected in sequence, and a plurality of liquid outlet holes are opened on the outer side of the hollow column 454. The conveying component 44 conveys the tooling component 45 through the feed port 411. The rotation speed of the conveying component 44 is controlled so that the precision rolled product falling into the shell 41 is sleeved on the hollow column 454. And because the electric valve also rotates with the conveying component 44, in order to avoid the entanglement of the wires caused by the connection of the wires, a power supply battery is first installed on the hollow plate 451 or the electric valve, and then the electric valve is connected to the control system through the wireless communication module so as to wirelessly control the operation of the electric valve.

[0090] In order to clean the outer wall of the precision rolled product, a liquid tank 46 is fixed to the top of the cleaning chamber 42, and a plurality of inclined spray plates 47 are fixed to the bottom of the liquid tank 46. The direction of the water curtain sprayed by the spray plate 47 is opposite to the conveying direction of the precision rolled product, so as to facilitate the flushing of the stamping oil on the outer wall of the precision rolled product. A liquid inlet pipe 4410 extending from one side of the outer shell 41 is fixed to one side of the liquid tank 46 for connecting to an external pipe. The cleaning liquid is conveyed to the liquid tank 46 through the liquid inlet pipe 4410, and the water curtain is sprayed through the spray plate 47 to clean the outer wall of the precision rolled product.

[0091] In order to clean the outer wall of the precision rolled product, an opening is provided on one side of the left frame 442 close to the conveyor belt 444, and a ring-shaped convex ring 445 is integrally formed on the inner wall of the left frame 442. A ring-shaped annular groove 446 is formed between the outer wall of the convex ring 445 and the inner wall of the left frame 442, and a hose 447 is surrounded by the annular groove 446. The hose can be a metal shaped hose that can be bent at will, and the hose 447 is connected to each hollow plate 451 through a spray pipe 456. When the hollow plate 451 moves with the conveyor belt 444, the hose 447 is driven to rotate in the annular groove 446 through the spray pipe 456.

[0092] A rotating tube 448 is also passed through the side of the left side frame 442 away from the conveyor belt 444, and the rotating tube 448 is rotatably connected to the left side frame 442 through a bearing, and one end of the rotating tube 448 close to the roller 443 is closed, and one end of the rotating tube 448 extending out of the left side frame 442 is connected to a liquid inlet pipe 4410, which passes through one side of the housing 41 and is fixed to the housing 41, and the liquid inlet pipe 4410 is rotatably connected to the rotating tube 448 through a sealed bearing;

[0093] The hose 447 is connected to the end of the rotating tube 448 in the left frame 442 through the connecting tube 449. The connecting tube 449 is a bellows or a metal shaped hose that can be bent and stretched at will. The connecting tube 449 is arranged outside the convex ring 445, so that the hose 447 drives the connecting tube 449 and the rotating tube 448 to rotate around the central axis of the rotating tube 448 when rotating. The tooling assembly 45 will also move with the conveying assembly 44 when cleaning the inner wall of the product. At this time, the state of the above parts is: the hollow plate 451 drives the liquid spraying tube 456 to move, and the liquid spraying tube 456 drives the hose 447 to rotate along the annular groove 446. At the same time, the connecting tube 449 rotates and stretches with the hose 447, and drives the rotating tube 448 to rotate. Therefore, when the tooling assembly 45 moves with the conveying assembly 44, the supply of liquid in the tooling assembly 45 can be guaranteed.

[0094] In the present invention, one end of the liquid inlet pipe 4410 extending outside the outer shell 41 is connected to the external pipe, and the liquid is pumped into the hollow plate 451 through the liquid inlet pipe 4410, the rotating pipe 448, the connecting pipe 449, the hose 447, and the liquid spraying pipe 456. The liquid is then sprayed out through the pipeline 452, the hollow disk 453, the hollow column 454 and the liquid outlet hole on the hollow column 454 to clean the inner wall of the precision rolled product.

[0095] In order to further improve the cleaning effect, a blade 455 is fixed at the outer end of the pipe 452, and the blade 455 is arranged inside the hollow plate 451, and the spray pipe 456 is arranged on one side of the blade 455. The liquid sprayed by the spray pipe 456 can drive the blade 455 to rotate, thereby driving the pipe 452, the hollow disk 453, the hollow column 454 and the precision rolled product to rotate, so as to facilitate the water curtain to comprehensively clean the outer wall of the product.

[0096] The steps of the present invention for integrated cleaning, drying and conveying of the precision rolled products after stamping are as follows:

[0097] Step 1: The precision rolled product after stamping falls into the housing 41 along the guide groove 205 and the feed port 411, and the product is sleeved on the hollow column 454 of the tooling assembly 45. The conveying assembly 44 conveys the tooling assembly 45 to carry the product. When the hollow plate 451 carries the block 457 and passes through the first group of opposing photoelectric sensors 48, the signal between the transmitter and the receiver of the first group of opposing photoelectric sensors 48 is interrupted, and the control system starts the electric valve to open the pipeline 452. At this time, the liquid is pumped into the hollow plate 451 through the liquid inlet pipe 4410, the rotating pipe 448, the connecting pipe 449, the hose 447, and the liquid spraying pipe 456, and the liquid is sprayed through the pipeline 452, the hollow plate 453, the hollow column 454 and the liquid outlet hole on the hollow column 454 to clean the inner wall of the product;

[0098] Step 2: At the same time, the liquid sprayed from the spray pipe 456 can drive the blade 455 to rotate, thereby driving the pipe 452, the hollow disk 453, the hollow column 454 and the product to rotate, and the water curtain sprayed from the spray plate 47 on the top of the product fully cleans the outer wall of the product. At the same time, the spraying direction of the water curtain is opposite to the conveying direction of the product, flushing the stamping oil on the outer wall of the product to improve the cleaning effect;

[0099] The present invention can choose to deliver cleaning liquid to clean the stamping oil on the product, or rinse with clean water after cleaning. It is worth noting that the electrical products located in the cleaning chamber 42 of the present invention are all waterproof products or waterproof designs to avoid water damage;

[0100] Step 3: When the hollow plate 451 carries the stopper 457 and passes through the second group of through-beam photoelectric sensors 48, the signal between the transmitter and the receiver of the second group of through-beam photoelectric sensors 48 is interrupted, and the control system closes the electric valve to close the water flow of the tooling assembly 45;

[0101] Step 4: The cleaned product is conveyed to the drying chamber 43, where it can be heated and dried by a heater or by a hot air blower. The conveying speed of the conveying assembly can be adjusted as needed to adjust the drying time so that the product is completely dry.

[0102] Afterwards, the dried precision rolled products are sorted, such as Figure 10-11 As shown, the organizing part 5 includes a frame 51, a circular groove 52 disposed on the top of the frame 51, and a storage tray 53 disposed in the circular groove 52;

[0103] The storage tray 53 includes a circular tray 531, a square plug rod 533, a square socket 534 and a plurality of sleeves 532. The plurality of sleeves 532 are fixed to the top of the circular tray 531. The square plug rod 533 is fixed to the center of the bottom end of the circular tray 531. The square socket 534 is opened at the center of the top end of the circular tray 531, and the square socket 534 is adapted to the square plug rod 533. Two handles are fixed at the top edge of the circular tray 531 to facilitate taking and placing the storage tray 53.

[0104] A rotating rod 521 is rotatably arranged at the bottom end of the circular groove 52, and the rotating rod 521 is driven to rotate by a driving device installed in the rotating rod 521. The driving device may be a stepping motor or other device. A square slot 522 adapted to the square plug rod 533 is provided at the top of the rotating rod 521. The square plug rod 533 is inserted into the square slot 522 to drive the storage disk 53 to rotate. An XY driving module for driving the circular groove 52 to adjust its position is also fixed at the top of the frame 51.

[0105] First, the position of the sleeve 532 is adjusted by adjusting the position of the circular groove 52, and then the rotating rod 521 is driven by the driving motor to rotate and drive the square plug rod 533 and the circular disc 531 to rotate step by step at a certain angle so that the precision rolled products that have been cleaned and dried on the tooling assembly 45 fall and are respectively sleeved on the sleeves 532 for sorting. When all the sleeves 532 on a storage tray 53 are sleeved with products, the personnel lift the storage tray 53 out, put the next storage tray 53 into the circular groove 52 to continue loading products, and the storage tray 53 filled with products is inserted into the square socket 534 of another storage tray 53 through the square plug rod 533, so that multiple storage trays 53 can be stacked, avoiding the problem of personnel sorting after multiple products are piled together, saving human resources.
