Description

TECHNICAL FIELD

[0001] The present application relates to a punching mechanism, in particular to an adjustable punching mechanism for lamp processing, belonging to the technical field of lamp processing. BACKGROUND

[0002] In the field of lamp processing, as a core appearance and functional component, the forming processing of the lampshade needs to complete two key processes of stretch forming and top punching in turn. Among them, the core purpose of the lampshade top punching is to provide precise and matched hole positions for wire installation, to ensure the stability of subsequent wire setting and fixing, and directly affects the circuit connection reliability and assembly efficiency of the lamp, and the hole position precision and processing consistency are strictly required.

[0003] At present, the existing lampshade punching device generally adopts a fixed structure design of a single lower die. Since the stretch-formed lampshade has a certain shape, it is not convenient to use automatic feeding and punching, so the whole feeding and taking operation is completed by manual labor during the punching process. First, the stretch-formed lampshade is accurately placed in the lower die station by manual labor to ensure that the top to be punched is aligned with the punch. After the punching operation of the wire installation hole is completed, the finished product needs to be taken out manually after the punching action is completely finished, and the feeding preparation of the next lampshade can be carried out.

[0004] Under this processing mode, the feeding and discharging operation and the punching process are in a serial execution state, which leads to a long downtime waiting time of the equipment, and the lampshade and the lower die are closely attached, which is not convenient when taking out. Not only does it increase the labor force, but it also seriously restricts the punching processing rate. At the same time, the metal debris generated during the punching process is easily left on the surface of the lower die, which cannot be self-cleaned after the punching is completed, and will cause problems such as scratches and stains on the surface of the lampshade in subsequent processing, affecting the appearance integrity and quality consistency of the product. In addition, in order to realize the cleaning of the debris, some improved equipment needs to be equipped with an independent power source, which leads to a complex equipment structure, increased energy consumption, and further increases the production cost.

[0037] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0038] Example 1

[0039] like Figures 1-9 As shown, this embodiment provides an adjustable stamping mechanism for lamp processing, including a base 1, a frame 2 fixedly installed on the top of the base 1, a stamping rod 3 vertically sliding on the top of the frame 2, an upper die base 4 fixedly installed at the bottom of the stamping rod 3, and an upper die 5 fixedly installed at the bottom of the upper die base 4.

[0040] The top of the base 1 is symmetrically provided with guide rails 6 along the length direction. The top of the guide rails 6 is slidably provided with a slide plate 7.

Both ends of the slide plate 7 are provided with blanking holes 12 for discharging punching waste.

[0041] The side of the slide plate 7 is provided with a reciprocating mechanism 10, which is used to drive the slide plate 7 to move back and forth along the guide rail 6. The reciprocating mechanism 10 is linked with the stamping rod 3, and drives the slide plate 7 to move back and forth as the stamping rod 3 rises and falls.

[0042] Each of the lower molds 9 is equipped with a lifting mechanism 11, which is used to lift the stamped lampshade and clean the surface of the lower mold 9.

[0043] The lifting mechanism 11 includes a sliding hole 1101, which is located in the middle of the lower mold 9. A push rod 1102 is vertically slidably mounted inside the sliding hole 1101, extending through the discharge hole 12 to the bottom of the slide plate 7. A lower guide groove 1104 is vertically provided at the bottom end of the push rod 1102. A limit rod 1103 is fixed inside the discharge hole 12, passing through the lower guide groove 1104. A retaining ring 1105 is fixed at the middle position of the push rod 1102. A sliding ring 1106 is fitted at the top of 102, and the sliding ring 1106 can slide along the length of the push rod 1102. The top of the sliding ring 1106 fits against the inner top of the lower mold 9. A third spring 1107 is provided between the sliding ring 1106 and the fixed ring 1105. The push rod 1102 passes through the inside of the third spring 1107. Guide plates 1115 that cooperate with the push rod 1102 are provided at both ends of the top of the base 1 and between the two sets of guide rails 6. A cleaning component is provided inside the push rod 1102.

[0044] The cleaning assembly comprises a cylinder 1108 which is arranged in the middle position inside the top rod 1102, the top end of the top rod 1102 is vertically provided with an upper guide groove 1109, the bottom end of the upper guide groove 1109 is in communication with the inside of the cylinder 1108, the inside of the cylinder 1108 is vertically slidably provided with a piston 1110, the top end of the piston 1110 is fixedly provided with a fixed rod 1111, the inside of the sliding ring 1106 is fixedly provided with a cross rod 1112, the cross rod 1112 passes through the inside of the upper guide groove 1109 and is fixedly connected with the fixed rod 1111, the outside of the top end of the top rod 1102 is uniformly provided with exhaust ports 1114 in the circumferential direction, and the bottom end of the cylinder 1108 is provided with an exhaust pipe 1113 which is in communication with the exhaust ports 1114.

[0045] The total working principle is as follows: after the equipment is started, the stamping rod 3 on the rack 2 is connected with the power source, the upper die seat 4 and the upper die 5 are driven to vertically descend, the lower die 9 on the slide plate 7 is accurately matched, the blanking work of the lampshade top wire installation hole is completed, and the waste generated by blanking is directly discharged through the blanking hole 12 on the slide plate 7. During the stamping process, the lifting action of the stamping rod 3 is linked with the slide plate 7 through the reciprocating mechanism 10, the slide plate 7 is driven to reciprocate along the guide rail 6 on the base 1, and the lower dies 9 at both ends of the slide plate 7 are alternately switched to the stamping station. When a group of lower dies 9 are subjected to stamping work, another group of lower dies 9 can synchronously complete manual feeding, without waiting for the stamping to end, so that the machining and feeding can be carried out in parallel.

[0046] After the stamping is completed, when the slide plate 7 drives the lower die 9 to move to the material taking station, the bottom end of the top rod 1102 is in contact with the guide plate 1115, the inclined surface of the guide plate 1115 makes the top rod 1102 vertically rise along the slide hole 1101. The lower guide groove 1104 on the top rod 1102 cooperates with the limiting rod 1103 in the blanking hole 12 to limit the movement track of the top rod 1102, so as to ensure the accuracy of the lifting action. The top end of the top rod 1102 is in contact with the lampshade, and the lampshade is stably lifted away from the lower die 9; during the lifting process, the inner top of the lower die 9 extrudes the sliding ring 1106, so that the sliding ring 1106 slides downward along the top rod 1102 and compresses the third spring 1107;

[0047] When the sliding ring 1106 slides downward, the inner horizontal rod 1112 moves downward along the upper guide groove 1109, and the horizontal rod 1112 pushes the piston 1110 to move vertically downward in the cylinder body 1108 through the fixed rod 1111. The piston 1110 extrudes the gas in the cylinder body 1108, so that the gas is sprayed out of the exhaust port 1114 at the top end of the top rod 1102 through the exhaust pipe 1113, forming a directional gas flow. The gas flow diffuses to the surface of the lower die 9, blows away the waste debris remaining after punching, avoids the debris from adhering to the surface of the lower die 9 to cause scratches or stains during subsequent lampshade processing, and protects the appearance quality of the product. After the lampshade is removed, a new lampshade to be punched is pre-installed, and when the next cycle station is switched, the third spring 1107 pushes the sliding ring 1106 to reset, preparing for the next lifting. At the same time, the piston 1110 moves upward, forming a negative pressure in the cylinder body 1108, and external air is supplemented to reserve gas for the next cleaning.

[0048] Embodiment 2

[0049] The scheme in Embodiment 1 will be further introduced in combination with a specific working mode, and details are described below:

[0050] In this embodiment, the reciprocating mechanism 10 includes a rectangular frame 1001, a slide rod 1002, a push rod 1003, a rotating rod 1004, and a rotating assembly. The rectangular frame 1001 is parallel to the width direction of the base 1 and is fixed to the side edge of the slide plate 7. The slide rod 1002 is slidably arranged inside the rectangular frame 1001 along the length direction. The push rod 1003 is installed at the top end of the slide rod 1002. The rotating rod 1004 is vertically fixed to the end of the push rod 1003 away from the slide rod 1002. The rotating assembly is arranged at the top end of the rotating rod 1004.

[0051] Partial working principle: when the punching rod 3 descends, the rotating assembly does not drive the rotating rod 1004 to rotate, and at this time, the position of the lower die 9 at the top of the slide plate 7 is fixed. After the punching is completed, the punching rod 3 rises by a distance, and after the mold opening action is completed, the rotating assembly drives the rotating rod 1004 and the push rod 1003 to rotate one hundred and eighty degrees as the punching rod 3 continues to move upward, moving the formed lampshade to one end, and moving another group of pre-installed lampshades to the lower side of the upper die 5 for the punching preparation stage.

[0052] In the embodiment, the rotating assembly comprises a sleeve 1005, a column rod 1006, an arc-shaped guide groove 1008, a straight guide groove 1009, a mounting sleeve 1010, a limiting plug 1011, a second spring 1012, a bearing 1013 and a connecting rod 1014, the sleeve 1005 is vertically fixed on the rack 2, the column rod 1006 is rotatably arranged in the sleeve 1005 and can be telescopic along the circumference of the sleeve 1005, the straight guide grooves 1009 are symmetrically arranged on the two sides of the column rod 1006, the arc-shaped guide groove 1008 is arranged between the middle position of the straight guide groove 1009 and the top end of the other straight guide groove 1009, the depth of the top end of the straight guide groove 1009 is greater than that of the top end of the arc-shaped guide groove 1008, the depth of the bottom end of the straight guide groove 1009 is greater than that of the top end, and the depth of the bottom end of the straight guide groove 1009 is the same as that of the bottom end of the arc-shaped guide groove 1008, the bottom of the side of the sleeve 1005 is provided with the mounting sleeve 1010 which is in communication with the inside of the sleeve 1005, the limiting plug 1011 is slidably arranged in the mounting sleeve 1010, the second spring 1012 is arranged between the limiting plug 1011 and the inner end of the mounting sleeve 1010, the limiting plug 1011 slides in the arc-shaped guide groove 1008 and the straight guide groove 1009, the bottom end of the column rod 1006 is slidably connected with the rotating rod 1004, the bottom end of the column rod 1006 is vertically provided with a guide hole, the rotating rod 1004 is a polygonal prism, the bearing 1013 is arranged on the outside of the bottom end of the column rod 1006, and the outer ring of the bearing 1013 is fixedly connected with the connecting rod 1014 and the punching rod 3.

[0053] Local working principle: when the punching rod 3 descends, the bearing 1013 is pulled through the connecting rod 1014, so as to drive the column rod 1006 to be telescopic downwards along the sleeve 1005, the rotating rod 1004 slides into the column rod 1006, the position of the rotating rod 1004 is unchanged, and in the process of the column rod 1006 moving downwards, the limiting plug 1011 moves vertically in the straight guide groove 1009 and cannot control the rotation of the column rod 1006, at this time, the position of the top of the sliding plate 7 and the lower die 9 is fixed, after the punching is completed, at this time, the limiting plug 1011 is located at the lowest end of the straight guide groove 1009, then the mold is opened, after the upper die 5 and the lower die 9 are completely separated, at this time, the limiting plug 1011 is located at the depth difference position on the straight guide groove 1009 and at the bottom end of the arc-shaped guide groove 1008, with the column rod 1006 continuing to move upwards driven by the punching rod 3, the limiting plug 1011 slides into the arc-shaped guide groove 1008 and controls the rotation of the column rod 1006, the column rod 1006 drives the rotating rod 1004 and the pushing rod 1003 to rotate, changes the force direction of the sliding rod 1002, realizes the movement of the sliding plate 7 and replaces the position of the lower die 9, after the column rod 1006 is reset driven by the punching rod 3, the limiting plug 1011 moves into the straight guide groove 1009 again, to prepare for the next action, the depth design of the straight guide groove 1009 and the arc-shaped guide groove 1008 ensures that the limiting plug 1011 slides smoothly and has no jamming phenomenon.

[0054] In this embodiment, the slide rod 1002 is cylindrical, and the slide rod 1002 is rotatably connected to the lever 1003 via a bearing.

[0055] Local working principle: The rotation of lever 1003 can be converted into linear sliding of slide rod 1002 within rectangular frame 1001, avoiding wear at the connection point due to relative movement, reducing sliding resistance, ensuring the smoothness and synchronization of slide plate 7 movement, and guaranteeing the positioning accuracy when switching between the two sets of lower molds 9.

[0056] In this embodiment, a first spring 1007 is provided between the top end of the column rod 1006 and the inner top end of the sleeve 1005, and the two ends of the first spring 1007 abut against the column rod 1006 and the inner top end of the sleeve 1005, respectively.

[0057] Local working principle: When the stamping rod 3 descends and pulls the column rod 1006 downward, the first spring 1007 releases elastic potential energy to ensure that the column rod 1006 responds quickly to move downward. When the stamping rod 3 pulls the column rod 1006 upward, the first spring 1007 is compressed.

[0058] In this embodiment, a ball bearing is rotatably mounted at the bottom end of the top rod 1102, and the bottom of the ball bearing contacts the top of the base 1.

[0059] Local working principle: The ball bearing mounted on the bottom of the push rod 1102 directly contacts the top of the base 1, converting the sliding friction between the push rod 1102 and the base 1 into rolling friction, which greatly reduces the resistance when the slide plate 7 moves, reduces component wear, and at the same time ensures that the push rod 1102 slides more smoothly on the guide plate 1115, avoiding delays or jamming of the lifting action due to excessive friction.

[0060] In this embodiment, a rubber block is fixed to the top of the push rod 1102, and the top surface of the rubber block is flush with the top surface of the lower mold 9.

[0061] Local working principle: The rubber block at the top of the ejector rod 1102 is soft and its top surface is flush with the top surface of the lower mold 9. During stamping, the rubber block adheres to the bottom surface of the lampshade, which not only does not affect the stamping accuracy of the lampshade, but also avoids hard contact with the lampshade during the ejection process, thus preventing scratches. The elasticity of the rubber block can buffer the impact force during ejection, ensuring that the lampshade is smoothly released from the lower mold 9, reducing the risk of falling and being damaged.

[0062] In this embodiment, grooves that cooperate with the guide rail 6 are provided on both sides of the bottom end of the slide plate 7 along the length direction, and a ball bearing that fits with the guide rail 6 is rotatably installed on the top of the groove.

[0063] Local working principle: the groove at the bottom end of the slide plate 7 precisely matches the guide rail 6, playing a guiding and positioning role, ensuring the smooth movement of the slide plate 7 along the length direction and avoiding deviation from affecting the fitting accuracy of the upper and lower molds. The top of the groove has a ball, which reduces the wear and tear of the components caused by long-term reciprocating motion, prolongs the service life of the equipment, and reduces the friction coefficient, making the slide plate 7 move more smoothly and labor-saving.

[0064] Example 3

[0065] The schemes in Examples 1 and 2 will be further introduced in combination with specific working modes, as described below:

[0066] In the initial state, the two groups of lower molds 9 on the slide plate 7 are respectively in the "punching standby station" and the "feeding station". The artificial first pre-assembles the lampshade after stretch forming to the lower mold 9 in the "feeding station", ensuring that the punching position at the top end of the lampshade matches the positioning of the lower mold 9. After starting the equipment, the punching rod 3 on the rack 2 is connected to the power source and vertically descends, driving the upper mold 5 to move downward synchronously, and precisely matches the lower mold 9 in the "punching standby station", completing the blanking operation of the lampshade top lead installation hole, and the waste produced by blanking is directly discharged through the blanking hole 12 on the slide plate 7, avoiding the accumulation of waste.

[0067] During the punching process, the downward movement of the punching rod 3 pulls the bearing 1013 through the connecting rod 1014, and then drives the column rod 1006 to stretch and retract downward along the sleeve 1005. At this time, the rotating rod 1004 slides into the guide hole at the bottom end of the column rod 1006, the linear guide groove 1009 on the side of the column rod 1006 matches the limiting plug 1011 on the sleeve 1005, the limiting plug 1011 vertically slides in the linear guide groove 1009, does not trigger the rotation of the column rod 1006, ensures the position of the lower mold 9 in the "punching standby station" is fixed, and guarantees the punching accuracy. At the same time, the artificial in the "feeding station" can synchronously complete the pre-assembly of the next lampshade, without waiting for the end of the punching process, breaking the traditional serial processing mode.

[0068] After the punching is completed, the punching rod 3 moves upward for a distance, realizing the opening and separation of the upper mold 5 and the lower mold 9. As the punching rod 3 continues to move upward, the column rod 1006 is reset and moves upward synchronously under the elastic force of the first spring 1007. At this time, the limiting plug 1011 enters the arc-shaped guide groove 1008 from the bottom end of the linear guide groove 1009, and the guiding effect of the arc-shaped guide groove 1008 makes the column rod 1006 rotate circumferentially, and then drives the rotating rod 1004 and the push rod 1003 to rotate 180° synchronously. The rotation of the push rod 1003 is converted into the linear sliding of the slide rod 1002 in the rectangular frame 1001, pushing the slide plate 7 to move smoothly along the guide rail 6, switching the lower mold 9 in the "punching completion station" to the "material taking station", and switching the lower mold 9 in the "feeding completion station" to the "punching standby station", realizing the alternate switching of the two groups of lower molds 9.

[0069] When the lower die 9 of the "punching finished station" moves to the "material taking station" with the slide plate 7, the ball at the bottom end of the ejector rod 1102 contacts the guide plate 1115 on the base 1, the inclined surface of the guide plate 1115 guides the ejector rod 1102 to vertically rise along the slide hole 1101, the rubber block at the top end of the ejector rod 1102 flexibly contacts the bottom surface of the lampshade, and the lampshade is stably lifted away from the lower die 9, thereby solving the problem that the lampshade is closely attached to the lower die in the traditional processing and is inconvenient to take out. During the lifting process, the inner top of the lower die 9 extrudes the sliding ring 1106, so that the sliding ring 1106 slides downward along the ejector rod 1102 and compresses the third spring 1107; at the same time, the sliding ring 1106 drives the lateral rod 1112 on the inner side to move downward along the upper guide groove 1109, pushes the piston 1110 to move downward in the cylinder body 1108 through the fixed rod 1111, extrudes the gas in the cylinder body 1108, and the gas is sprayed from the exhaust port 1114 at the top end of the ejector rod 1102 through the exhaust pipe 1113, so that a directional airflow is formed and blows to the surface of the lower die 9, blows away the residual waste debris on the surface of the lower die 9, and avoids that the debris scratches the surface of the lampshade in subsequent processing.

[0070] The punching rod 3 rises to the limit position, the column rod 1006 moves to the topmost part of the sleeve 1005, the limiting plug 1011 returns to the linear guide groove 1009 on the other side from the arc-shaped guide groove 1008, the artificial takes down the lifted formed lampshade, pre-installs a new lampshade to be punched, and enters the next working cycle.

[0071] The above is only a further embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and concept of the present application within the scope disclosed by the present application, which belongs to the protection scope of the present application.
