Description

Technical Field

[0001] This utility model relates to the field of drying ovens, specifically a mobile drying oven assembly that facilitates the production of stamped parts on a production line. Background Technology

[0002] Stamping of metal shell parts is a processing technology that uses specialized equipment such as punch presses to apply pressure to raw materials such as metal strips, causing them to undergo plastic deformation or separation, thereby obtaining metal shell parts with specific shapes and sizes. It is widely used in many industries such as electronics, electrical appliances, and hardware, providing key components such as shells for various products.

[0003] In the common production process of metal shell parts, the strip material first enters the punch press and is stamped to form bulk stamped parts. Then, these bulk parts need to go through the packaging process and are then transported to the cleaning and drying production line for further processing. After cleaning and drying, they are packaged again to finally obtain finished bulk parts.

[0004] In the existing stamping process of hardware parts, cutting oil is usually applied to reduce friction during stamping and protect the mold and part surface. After the parts are stamped, personnel need to transport the stamped parts to the cleaning and drying production line to clean the cutting oil on the parts. Only after the cleaning and drying operations can the products be packaged. However, this process involves multiple manual handling and transfer between different processes, which not only consumes a lot of time but also requires a lot of manpower, resulting in low overall work efficiency. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a mobile oven assembly that facilitates the production of stamped parts on a production line, in order to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile oven assembly for convenient production of stamped parts, comprising an oven and a base, wherein the oven is mounted on the top of the base, and three sets of heating coils are installed inside the oven. An inlet and an outlet are respectively provided on both sides of the oven. Two sets of fixing plates are fixed on both sides of the top of the base, and rotating rods are provided at both ends of each fixing plate. A stepper motor is mounted at the end of one set of rotating rods. Two sets of drive rollers are provided on the outer walls of both sets of rotating rods, and a conveyor belt is sleeved on the outer wall of each drive roller. A controller is installed on the outer wall of the oven.

[0007] By adopting the above technical solution, the problem of multiple manual handling and transfer between different processes involved in cleaning and collecting stamped metal parts is solved. After the strip is stamped, the parts formed by the stamping process slide onto the conveyor belt, which transports them at a uniform and slow speed. During the conveyor belt transport, the parts pass through an oven, where the heating coils inside the oven bake and heat the parts, accelerating the evaporation rate of the volatile cutting oil adhering to the surface of the parts, thereby cleaning the cutting oil from the surface of the parts. When the parts are conveyed to the end of the conveyor belt, personnel can collect the parts, thus reducing the number of times the parts are handled after stamping.

[0008] The present invention is further configured such that gears are installed on the outer walls of both sets of rotating rods, and toothed belts are sleeved on the outer walls of the gears.

[0009] Preferably, when the rotating rod connected to the end of the stepper motor rotates, the rotating rod connected to the end of the stepper motor drives the rotating rod at the other end of the conveyor belt to rotate through the toothed belt.

[0010] The present invention is further configured such that the conveyor belt is a stainless steel mesh belt, and the two ends of the base are fixed with support plates, and the top of the support plate is connected to the end of the fixed plate.

[0011] Preferably, the conveyor belt of the stainless steel mesh belt has a large number of holes on its surface, so that the air heated by the electric heating coil inside the oven can come into contact with the bottom of the parts through the holes, thereby allowing the cutting oil attached to the bottom of the parts to be heated and evaporated.

[0012] The present invention is further configured such that the bottom of the base is provided with four sets of lifting feet, and the lifting feet are driven by a hydraulic system, and the bottom of the lifting feet is equipped with casters.

[0013] Preferably, the height of the oven can be adjusted by extending and retracting the lifting feet at the bottom of the base, so that the oven can be matched with punch presses of different heights.

[0014] The present invention is further configured such that the three sets of heating coils are respectively installed on the top and both sides of the inner wall of the oven, and the controller is electrically connected to the heating coils, the lifting feet and the stepper motor.

[0015] Preferably, the temperature of the three sets of heating coils can be independently controlled by the controller.

[0016] The present invention is further configured such that a sliding groove is provided at the bottom of the oven, and a sliding rail is installed on one side of the fixed plate.

[0017] Preferably, the oven can be moved horizontally on top of the conveyor belt by pushing the oven.

[0018] The present invention is further configured such that the inner walls of the inlet and outlet are provided with limiting grooves, a sealing plate is installed inside the limiting groove, an adjusting rod is connected to the top of the sealing plate, and a knob is provided at the top of the adjusting rod.

[0019] Preferably, the sealing plate adjusts the diameter of the inlet and outlet to reduce the outflow of high-temperature gas from the oven through the inlet or outlet.

[0020] The present invention is further configured such that the middle part of the adjusting rod is threadedly connected to the inside of the oven, and a connecting block is provided at the bottom of the adjusting rod.

[0021] Preferably, the operator can rotate the knob to raise or lower the adjusting rod.

[0022] The present invention is further configured such that the inner wall of the oven is covered with a heat insulation board, and the heat insulation board and the heating coil are kept at a distance of 2cm. The heat insulation board is made of ceramic fiber cotton.

[0023] Preferably, the heat insulation board can block the heat inside the oven from being conducted to the outer wall of the oven, preventing burns when people touch the outer wall of the oven, and the heat insulation board can also keep the temperature inside the oven warm.

[0024] The present invention is further configured such that a punch press is provided on one side of the base, a control base is installed at the bottom of the punch press, a hydraulic cylinder is provided at the top of the punch press, a stamping plate is fixed at the end of the hydraulic cylinder, and a slide is provided on one side of the punch press.

[0025] Preferably, the hydraulic cylinder pushes the stamping plate downwards, so that the stamping plate stamps the strip through the stamping module at its bottom and the stamping module at the top of the press. When the strip is stamped, the stamped part slides off the ramp on one side of the press onto the conveyor belt.

[0026] In summary, the present invention has the following main advantages:

[0027] This invention solves the problem of multiple manual handling and inter-process transfers involved in cleaning and collecting stamped metal parts by setting up an oven, heating coil, base, conveyor belt, and controller. After the strip is stamped, the formed parts slide onto the conveyor belt, which transports them at a uniform speed. During the conveyor belt transport, the parts pass through the oven, where the heating coil inside bakes and heats the parts, accelerating the evaporation rate of volatile cutting oil adhering to the surface of the parts, thus cleaning the cutting oil from the surface of the parts. When the parts are conveyed to the end of the conveyor belt, personnel can collect the parts, thereby reducing the number of times the parts need to be handled after stamping.

[0028] This utility model incorporates a limiting groove, a sealing plate, an adjusting rod, a knob, and a connecting block. When the knob is rotated, the adjusting rod, which is fixed at one end of the knob, has a thread in the middle and is connected to the oven via the thread. This allows the adjusting rod to push the sealing plate downwards during rotation. The sealing plate then blocks the inlet or outlet, increasing the sealing of both sides of the oven and reducing the outflow of high-temperature air from the inlet and outlet on both sides of the oven.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The embodiments of this utility model will be described below based on its overall structure.

[0041] First embodiment:

[0042] Please see Figure 1 — Figure 7 The system includes an oven 1 and a base 3. The oven 1 is mounted on top of the base 3. Three sets of heating coils 104 are installed inside the oven 1. An inlet 102 and an outlet 103 are located on both sides of the oven 1. Two sets of fixing plates 4 are fixed to the top of the base 1 on both sides. Rotating rods 404 are mounted at both ends of each fixing plate 4. A stepper motor 405 is mounted at the end of one set of rotating rods 404. Two sets of drive rollers 403 are mounted on the outer walls of both sets of rotating rods 404. A conveyor belt 402 is fitted onto the outer wall of the drive rollers 403. A controller 101 is mounted on the outer wall of the oven 1. This system solves the problem of cleaning and collecting stamped metal parts. The process involves multiple manual handling and transfers between different processes. After the strip is stamped, the parts formed by the stamping process slide onto the conveyor belt 402. The conveyor belt 402 transports the parts at a uniform and slow speed. During the process of being transported by the conveyor belt 402, the parts pass through the oven 1. The heating coil 104 inside the oven 1 bakes and heats the parts, which accelerates the evaporation rate of the volatile cutting oil adhering to the surface of the parts, thereby cleaning the cutting oil on the surface of the parts. When the parts are transported to the end of the conveyor belt 402, the personnel can collect the parts, thereby reducing the number of times the parts are handled after the stamping process.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 4Gears 406 are installed on the outer walls of both sets of rotating rods 404. Toothed belts 407 are sleeved on the outer walls of the gears 406. When the rotating rod 404 connected to the end of the stepper motor 405 rotates, the rotating rod 404 connected to the end of the stepper motor 405 drives the rotating rod 404 at the other end of the conveyor belt 402 to rotate through the toothed belts 407.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The conveyor belt 402 is made of stainless steel mesh belt. Support plates 401 are fixed at both ends of the base 3, and the top of the support plate 401 is connected to the end of the fixed plate 4. The surface of the conveyor belt 402, which is made of stainless steel mesh belt, has a large number of holes, so that the air inside the oven 1 heated by the heating coil 104 can come into contact with the bottom of the parts through the holes, thereby allowing the cutting oil attached to the bottom of the parts to be heated and evaporated.

[0045] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The base 3 has four sets of lifting feet 301 at its bottom, and the lifting feet 301 are driven by a hydraulic system. The bottom of the lifting feet 301 is equipped with casters 302. The base 3 can adjust the height of the oven 1 by extending and retracting the lifting feet 301 at its bottom, so that the oven 1 can be matched with punch presses 5 of different heights.

[0046] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 5 Three sets of heating coils 104 are respectively installed on the top and both sides of the inner wall of the oven 1. The controller 101 is electrically connected to the heating coils 104, the lifting platform 301 and the stepper motor 405. Personnel can independently control the temperature of the three sets of heating coils 104 through the controller 101.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 5 The bottom of the oven 1 is provided with a slide 107, and a slide rail 303 is installed on one side of the fixed plate 4. Personnel can move the oven 1 horizontally on the top of the conveyor belt 402 by pushing the oven 1.

[0048] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 and Figure 6 The inner walls of the inlet 102 and the outlet 103 are provided with limiting grooves 106. A sealing plate 2 is installed inside the limiting groove 106. An adjusting rod 201 is connected to the top of the sealing plate 2. A knob 202 is provided at the top of the adjusting rod 201. The sealing plate 2 adjusts the size of the inlet 102 and the outlet 103, thereby reducing the outflow of high-temperature gas from the oven 1 through the inlet 102 or the outlet 103.

[0049] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 and Figure 7 The middle part of the adjusting rod 201 is threaded to the inside of the oven 1. A connecting block 203 is provided at the bottom of the adjusting rod 201. Personnel can rotate the knob 202 to raise and lower the sealing plate 2.

[0050] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The inner wall of the oven 1 is covered with a heat insulation board 105, and the heat insulation board 105 and the heating coil 104 are kept at a distance of 2cm. The heat insulation board 105 is made of ceramic fiber cotton. The heat insulation board 105 can block the heat inside the oven 1 from being conducted to the outer wall of the oven 1 through the oven 1, preventing people from being burned when they touch the outer wall of the oven 1. The heat insulation board 105 can also keep the temperature inside the oven 1 warm.

[0051] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A punch press 5 is provided on one side of the base 3. A control base 501 is installed at the bottom of the punch press 5. A hydraulic cylinder 502 is provided at the top of the punch press 5. A stamping plate 503 is fixed at the end of the hydraulic cylinder 502. A slide 504 is provided on one side of the punch press 5. The hydraulic cylinder 502 pushes the stamping plate 503 downward, so that the stamping plate 503 stamps the strip material through the stamping module at its bottom and the stamping module at the top of the punch press 5. When the strip material is stamped, the stamped part slides from the slide 504 on one side of the punch press 5 onto the conveyor belt 402.

[0052] Second embodiment:

[0053] Please see Figure 8 A receiving plate 6 is movably mounted on one end of the fixed plate 4, and the thickness of the receiving plate 6 is set to 2mm. Two sets of guide plates 602 are fixed on the top of the receiving plate 6, and the two sets of guide plates 602 are symmetrically arranged. A connecting post 601 is installed on one end of the receiving plate 6, and the end of the connecting post 601 is connected to the inner wall of the fixed plate 4. When the height of the base 3 is adjusted, the operator can flip the receiving plate 6 and place it on the slide 504 on one side of the punch press 5, so that the stamped parts can slide along the inclined slide. The part slides down the ramp 504 onto the receiving plate 6. Since the receiving plate 6 is still in an inclined state when it is placed on the ramp 504, the part can slide down the smooth inclined wall of the receiving plate 6 onto the conveyor belt 402. As the part slides along the receiving plate 6, the guide plates 602 on both sides of the receiving plate 6 guide the part towards the middle of the conveyor belt 402, so that the part slides down to the middle of the conveyor belt 402, thereby allowing the part to accurately enter the oven 1 through the feed port 102.

[0054] In practical operation, the present invention first places the strip material into the stamping area above the punch press 5. The operator can control the components on the punch press 5 through the control base 501 at the bottom of the punch press 5. As the hydraulic cylinder 502 pushes the stamping plate 503 downward, the stamping plate 503 stamps the strip material through the stamping module at its bottom and the stamping module at the top of the punch press 5. When the strip material is stamped, the hydraulic cylinder 502 drives the stamping plate 503 to move upward. Then the operator pushes another set of strip material to be stamped to the stamping area position on the punch press 5, so that the strip material to be stamped pushes the stamped part onto the slide 504 on one side of the punch press 5.

[0055] The parts slide down the ramp 504 on one side of the punch press 5 onto the conveyor belt 402. Before the strip is stamped, the operator controls the three sets of heating coils 104 and the stepper motor 405 installed inside the oven 1 via the controller 101 on one side of the oven 1. The stepper motor 405 drives the two sets of drive rollers 403 on the outer wall of the rotating rod 404 to rotate through the rotating rod 404 connected to its output end. The rotating rod 404 drives the toothed belt 407 to rotate through the gear 406 on its outer wall. The rotating toothed belt 407 drives another set of rotating rods 404 inside the conveyor belt 402 to rotate, causing the two sets of drive rollers 403 on the other set of rotating rods 404 to rotate. Because the conveyor belt 402, which uses a stainless steel mesh belt, is always taut under the pressure of the four sets of drive rollers 403, the conveyor belt 402 rotates slowly under the power of the stepper motor 405. The three sets of heating coils 104 inside the oven 1 are located above and on both sides. The direction of the baking is to bake the upper surface of the conveyor belt 402. When the stamped parts slide onto the conveyor belt 402, the conveyor belt 402 conveys the parts through the feed port 102 on one side of the oven 1 into the oven 1. The electric heating coil 104 inside the oven 1 heats and bakes the volatile cutting oil on the surface of the parts. The cutting oil attached to the surface of the parts is heated and its evaporation efficiency is accelerated. In addition, the surface of the conveyor belt 402, which is made of stainless steel mesh belt, has a large number of holes, so that the air heated by the electric heating coil 104 inside the oven 1 comes into contact with the bottom of the parts through the holes, so that the cutting oil attached to the bottom of the parts can also be heated and evaporated. During the conveying process of the parts on the conveyor belt 402, the electric heating coil 104 inside the oven 1 continues to bake the parts. Finally, the parts are conveyed out from the discharge port 103 on one side of the oven 1 via the conveyor belt 402. Personnel can collect the parts that have been stamped and cleaned and dried at the end of the conveyor belt 402.

[0056] If the height of the parts is low, the personnel can adjust the opening area of ​​the inlet 102 and outlet 103 on both sides of the oven 1. First, manually rotate the knob 202. Since the adjusting rod 201 fixed at one end of the knob 202 has a thread in the middle and the adjusting rod 201 is connected to the oven 1 by the thread, the adjusting rod 201 can push the sealing plate 2 downward during the rotation, increasing the sealing of both sides of the oven 1, thereby reducing the high temperature air inside the oven 1 from flowing out of the inlet 102 and outlet 103 on both sides of the oven 1.

[0057] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, but such modifications, substitutions, and variations are protected by patent law as long as they fall within the scope of the claims of the present invention.
