Description

Technical Field

[0001] This utility model relates to the field of enamel pot production technology, and in particular to an enamel pot blank stamping and forming device. Background Technology

[0002] The production of enamel pot blanks is a fundamental step in the manufacturing of enamel pots, and its quality directly affects the performance and appearance of the final product. This process uses low-carbon steel plates as the main raw material and, through a series of precise processing techniques, transforms the raw plates into a pot body prototype that meets the requirements of the enamel process.

[0003] Before the stamping process of enamel pot blanks, the pretreatment of the raw material sheet is crucial. Typically, the sheet needs to be cut using a shearing machine according to preset dimensional parameters to process it into blanks that meet the stamping requirements. This cutting process must ensure the accuracy of the blank dimensions, with deviations controlled within a very small range, to avoid material waste or forming defects during subsequent stamping.

[0004] However, if there are metal scraps or other impurities remaining from the cutting process on the contact surface between the sheet metal and the punch, these impurities are easily pressed into the surface of the blank during punch extrusion, or slide along the surface under pressure, thus forming obvious indentations or scratches on the blank surface. These surface defects directly affect the quality of the subsequent enamel layer coverage, leading to problems such as poor adhesion, pinholes, or even peeling of the enamel layer at the defective locations, seriously reducing the quality of the enamel pot. Therefore, an enamel pot blank stamping forming device is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of an enamel pot blank stamping forming device, comprising a machine body 1, a die 2 fixedly connected to the inner wall of the machine body 1, a groove 3 formed on the top of the inner wall of the die 2, the groove 3 being a circular groove with an inner diameter slightly larger than the inner diameter of the die 2, the groove 3 being used to limit the workpiece, a hydraulic cylinder 4 being fixedly connected through the top of the machine body 1, a slide plate 5 being slidably connected to the inner wall of the machine body 1, the piston rod of the hydraulic cylinder 4 being fixedly connected to the upper surface of the slide plate 5, starting the hydraulic cylinder 4 to drive the slide plate 5 to slide up and down on the inner wall of the machine body 1, a punch 6 being fixedly connected to the lower surface of the slide plate 5, the punch 6 and the die 2 being used to form the workpiece into a pot blank, a through groove 7 being formed on the inner wall of the machine body 1, a cleaning mechanism 8 being provided at the bottom of the slide plate 5, and a demolding mechanism 9 being provided on the inner wall of the machine body 1.

[0033] Reference Figure 2 - Figure 4 The cleaning mechanism 8 includes a tube 81, which is rotatably connected to the inner wall of the slide plate 5. As the slide plate 5 slides up and down, it drives the rotating cylinder 85 and the tube 81 to move up and down synchronously. A nozzle 82 is fixedly connected to the outer wall of the tube 81. As the tube 81 rotates back and forth, it drives two sets of nozzles 82 on its outer wall to swing back and forth. The back-and-forth swinging of the nozzles 82 allows the airflow to fully cover the upper surface of the workpiece and the bottom of the punch 6, ensuring thorough cleaning of impurities. Two sets of nozzles 82 are provided. The nozzles 82 are symmetrically and equidistantly distributed along the central axis of the insertion tube 81 on the outer wall of the tube 81. One set of nozzles 82 is inclined upwards, and the gas ejected from the upward-inclined nozzles 82 blows towards the bottom of the punch 6, thereby blowing away impurities at the bottom of the punch 6. The other set of nozzles 82 is inclined downwards, and the gas ejected from the downward-inclined nozzles 82 blows towards the upper surface of the workpiece, thereby blowing away residual metal chips and impurities on the upper surface of the workpiece. A flexible hose 83 is fixedly connected to the top end of the insertion tube 81. 83 is connected to the air outlet of the air pump. Gas is injected into the hose 83 through the air pump. At this time, the gas will enter the interior of the insertion tube 81 through the hose 83. The gas inside the insertion tube 81 will be ejected outward through the nozzle 82. A hollow rod 84 is fixedly connected to the outer wall of the insertion tube 81. A rotating cylinder 85 is rotatably connected through the inner wall of the slide plate 5. The rotating cylinder 85 is a hollow cylindrical structure. An eccentric rod 86 is fixedly connected to the top of the rotating cylinder 85. The axis of the eccentric rod 86 is offset from the axis of the rotating cylinder 85. The outer wall of the eccentric rod 86 is attached to the hollow rod 84. The inner wall of the slide plate 5 is rotated by the rotating cylinder 85. When the rotating cylinder 85 rotates, it can drive the insertion tube 81 to reciprocate on the inner wall of the slide plate 5 in conjunction with the eccentric rod 86 and the hollow rod 84. The rotating cylinder 85 is provided with a spiral groove 87. A crossbar 88 is fixedly connected to the inner wall of the through groove 7. The outer wall of the crossbar 88 is attached to the inner wall of the spiral groove 87. When the rotating cylinder 85 moves downward, the spiral groove 87 will be squeezed by the crossbar 88. At this time, under the guidance of the spiral groove 87 and the limiting effect of the crossbar 88, the rotating cylinder 85 rotates on the inner wall of the slide plate 5 while moving downward.

[0034] Reference Figure 2 - Figure 3 The demolding mechanism 9 includes a push rod 91, which is slidably connected to the inner wall of the machine body 1. The top end of the push rod 91 penetrates the cavity mold 2 and extends into the cavity mold 2. When the push rod 91 moves downward and resets, its top end will be flush with the bottom of the inner wall of the cavity mold 2. By sliding the push rod 91 upward, the molded blank inside the cavity mold 2 can be lifted upward, allowing the blank to move upward out of the cavity mold 2 so that the operator can remove the product. The push rod 91 is slidably connected to the cavity mold 2 at the penetration point. A spring 92 is fixedly connected to the bottom end of the push rod 91. The end of the spring 92 away from the push rod 91 is fixedly connected to the inner wall of the machine body 1. The wall, under the elastic action of spring 92, can drive the push rod 91 to slide downward and reset on the inner wall of the machine body 1. The outer wall of the push rod 91 is fixedly connected to the push plate 93. The end of the push plate 93 away from the push rod 91 extends to the inner wall of the through groove 7. The bottom end of the rotating cylinder 85 is fixedly connected to the limiting plate 94. The upper surface of the limiting plate 94 is attached to the lower surface of the push plate 93. When the rotating cylinder 85 drives the limiting plate 94 to move upward and contacts the lower surface of the push plate 93, the limiting plate 94 will push the push plate 93 upward, so that the push plate 93 drives the push rod 91 to slide upward on the inner wall of the machine body 1.

[0035] Working principle: Connect the hose 83 to the air outlet of the air pump. Inject gas into the hose 83 through the air pump. The gas will then enter the interior of the insertion tube 81 through the hose 83. The gas inside the insertion tube 81 will be sprayed out through the nozzle 82. Then, the workpiece is placed into the slot 3. Subsequently, the hydraulic cylinder 4 is activated to drive the slide plate 5 to slide downward on the inner wall of the machine body 1. As the slide plate 5 slides downward, it will drive the punch 6 to move downward synchronously. The downward movement of the punch 6 can squeeze the workpiece inside the slot 3, causing the workpiece to deform. At the same time, the punch 6 and the die 2 can form the workpiece into a pot blank. Meanwhile, the gas sprayed by the upwardly tilted nozzle 82 will blow towards the bottom of the punch 6, thereby blowing away the impurities at the bottom of the punch 6 and cleaning the punch 6. As the slide plate 5 slides downward, the gas sprayed by the downwardly tilted nozzle 82 will blow towards the upper surface of the workpiece, thereby blowing away the metal debris and impurities remaining on the upper surface of the workpiece. This ensures that the contact surface between the workpiece and the punch 6 is cleaned, preventing impurities from affecting the stamping quality of the pot blank.

[0036] As the slide plate 5 slides downwards, it drives the rotating cylinder 85 and the insertion tube 81 to move downwards synchronously. At the same time, the spiral groove 87 is squeezed by the crossbar 88 as the rotating cylinder 85 moves downwards. Under the guidance of the spiral groove 87 and the limiting effect of the crossbar 88, the rotating cylinder 85 rotates on the inner wall of the slide plate 5 while moving downwards. As the rotating cylinder 85 rotates, it drives the eccentric rod 86 to move back and forth against the inner wall of the hollow rod 84. At the same time, the eccentric rod 86 pushes and pulls the hollow rod 84 back and forth, causing the hollow rod 84 to swing back and forth and drive the insertion tube 81 to rotate back and forth on the inner wall of the slide plate 5. As the insertion tube 81 rotates back and forth, it drives the two sets of nozzles 82 on its outer wall to swing back and forth. Through the back and forth swing of the nozzles 82, the airflow blown out can fully cover the upper surface of the workpiece and the bottom of the punch 6, so that impurities can be fully cleaned and impurity residue can be effectively avoided.

[0037] As the rotating drum 85 moves downward, it drives the limiting plate 94 to move downward simultaneously. At this time, under the elastic action of the spring 92, the ejector rod 91 is pulled, causing the ejector rod 91 to slide downward on the inner wall of the machine body 1. Simultaneously, the ejector rod 91 drives the push plate 93 to move downward. After the ejector rod 91 moves downward and resets, its top end will be flush with the bottom of the inner wall of the cavity mold 2. When the rotating drum 85 moves upward and causes the limiting plate 94 to contact the lower surface of the push plate 93, the limiting plate 94 will push the push plate 93 upward, causing the push plate 93 to drive the ejector rod 91 to slide upward on the inner wall of the machine body 1. At the same time, the ejector rod 91 will stretch the spring 92. By sliding the ejector rod 91 upward, the formed pot blank inside the cavity mold 2 can be lifted upward, allowing the pot blank to be moved upward out of the cavity mold 2, so that the workers can take out the product, improve the convenience of demolding, and help improve the work efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
