Description

Technical Field

[0001] This utility model relates to the field of punching, and in particular to a punching device for silicone rubber products. Background Technology

[0002] Punching is a process that uses molds or cutting tools to apply external force to materials, causing them to separate or undergo plastic deformation.

[0003] A silicone rubber product punching device is a piece of equipment used to cut silicone rubber materials.

[0004] An existing silicone rubber product punching device has the following shortcomings: Silicone rubber products come in a wide variety, but their production processes are largely similar. The punching and cutting device is the core equipment in this process. However, existing punching and cutting devices have significant limitations. Their structures are generally quite simple, and the punching shapes are mostly fixed designs, making it impossible to flexibly adjust them according to the processing requirements of different types of silicone rubber products. This often necessitates replacing the entire mold or equipment each time a product is switched, increasing the user's procurement and maintenance costs, extending production preparation time, and causing numerous inconveniences in actual operation, making it difficult to adapt to diverse production needs. Utility Model Content

[0005] This invention eliminates the need to replace the entire mold set, significantly shortening the production preparation time during product changeover, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a silicone rubber product punching device, including a changing mechanism, wherein a conveying mechanism is fixedly connected to the bottom of the changing mechanism; the changing mechanism includes a connecting plate and a punching blade, an electric push rod is fixedly installed on the top of the connecting plate, a lifting plate is fixedly connected to the shaft end of the electric push rod, a set of clamping plates is slidably connected to the inner wall of the lifting plate, a set of first limiting rods is fixedly connected to the inner wall of the lifting plate, a first compression spring and a second compression spring are respectively sleeved on the outer wall of the first limiting rods, a first pad is fixedly connected to the bottom of the lifting plate, and a first magnet is fixedly connected to the inner wall of the first pad. Through the above components, it is convenient to quickly change the punching parts to adapt to the molding requirements of silicone rubber products of different shapes.

[0007] Preferably, one end of the first compression spring and the second compression spring are fixedly connected to the outer wall of the clamping plate, and the other end of the first compression spring and the second compression spring are fixedly connected to the inner wall of the lifting plate. The outer wall of the first limiting rod is slidably connected to the inner wall of the clamping plate. The clamping plate has an L-shaped structure. The two ends of the first compression spring and the second compression spring are respectively connected to the clamping plate and the lifting plate. Through elastic action, the clamping plate is stably located in the slot, thereby indirectly ensuring the connection stability between the punching blade and the lifting plate.

[0008] Preferably, a set of connecting blocks are fixedly connected to the top of the punching cutter, and a set of slots are opened on the inner wall of the connecting blocks. A second pad is fixedly connected to the top of the punching cutter, and a second magnet is fixedly connected to the inner wall of the second pad. The side of the first magnet opposite to the second magnet is the N pole, and the side of the second magnet opposite to the first magnet is the S pole. The second pad and the second magnet cooperate with the first pad and the first magnet to achieve double fixation of the punching cutter through the attraction of opposite poles.

[0009] Preferably, the conveying mechanism includes a frame, a set of sliders is slidably connected to the inner wall of the frame, and a transverse plate is fixedly connected to the opposite side of the two sliders. The arrangement of the transverse plate and the sliders constitutes a movable workpiece carrying platform.

[0010] Preferably, a lead screw is movably inserted into the inner wall of the frame, and a servo motor is fixedly installed on one side of the outer wall of the frame. The lead screw's outer wall thread passes through the inner wall of one of the sliders. The output end of the servo motor is fixedly connected to one end of the lead screw. The servo motor drives the lead screw to rotate.

[0014] 2. In this utility model, the slider and the transverse plate constitute a movable bearing platform. The servo motor drives the lead screw to move the slider, converting the rotational motion into linear motion, thereby realizing the automated and precise conveying of the workpiece. The second limiting rod and the lead screw form a double guiding structure, which effectively prevents the slider from deviating and ensures a smooth and reliable conveying process. The support legs, together with the anti-slip pads, improve the overall stability of the equipment. The PLC controller simplifies the operation process, allowing operators to quickly set process parameters and reduce manual intervention. This not only improves the efficiency of mass production but also reduces the difficulty of operation, further enhancing the equipment's adaptability to diverse production scenarios.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a silicone rubber product punching device, including a changing mechanism 1, with a conveying mechanism 2 fixedly connected to the bottom of the changing mechanism 1; the changing mechanism 1 includes a connecting plate 101 and a punching blade 104, an electric push rod 102 fixedly installed on the top of the connecting plate 101, a lifting plate 103 fixedly connected to the shaft end of the electric push rod 102, a set of clamping plates 110 slidably connected to the inner wall of the lifting plate 103, a set of first limiting rods 109 fixedly connected to the inner wall of the lifting plate 103, a first compression spring 113 and a second compression spring 114 respectively sleeved on the outer wall of the first limiting rods 109, a first pad 111 fixedly connected to the bottom of the lifting plate 103, and a first magnet 112 fixedly connected to the inner wall of the first pad 111. Through the above components, it is convenient to quickly change the punching parts to adapt to the molding requirements of silicone rubber products of different shapes.

[0020] like Figure 3 As shown, one end of the first compression spring 113 and the second compression spring 114 is fixedly connected to the outer wall of the clamping plate 110, and the other end of the first compression spring 113 and the second compression spring 114 is fixedly connected to the inner wall of the lifting plate 103. The outer wall of the first limiting rod 109 is slidably connected to the inner wall of the clamping plate 110. The clamping plate 110 has an L-shaped structure. The two ends of the first compression spring 113 and the second compression spring 114 are respectively connected to the clamping plate 110 and the lifting plate 103. Through elastic action, the clamping plate 110 is stably located in the slot 105, thereby indirectly ensuring the connection stability between the punching blade 104 and the lifting plate 103.

[0021] like Figure 2 As shown, a set of connecting blocks 108 are fixedly connected to the top of the punching blade 104. A set of slots 105 are opened on the inner wall of the connecting blocks 108. A second pad 106 is fixedly connected to the top of the punching blade 104. A second magnet 107 is fixedly connected to the inner wall of the second pad 106. The side opposite to the first magnet 112 and the second magnet 107 is the N pole, and the side opposite to the second magnet 107 and the first magnet 112 is the S pole. The second pad 106 and the second magnet 107 cooperate with the first pad 111 and the first magnet 112 to achieve double fixation of the punching blade 104 through the attraction of opposite poles.

[0022] like Figure 4 As shown, the conveying mechanism 2 includes a frame 201, and a set of sliders 208 are slidably connected to the inner wall of the frame 201. A transverse plate 202 is fixedly connected to the opposite side of the two sliders 208. The arrangement of the transverse plate 202 and the sliders 208 constitutes a movable workpiece carrying platform.

[0023] like Figure 5As shown, a lead screw 209 is movably inserted into the inner wall of the frame 201, and a servo motor 206 is fixedly installed on one side of the outer wall of the frame 201. The thread of the lead screw 209 passes through the inner wall of one of the sliders 208. The output end of the servo motor 206 is fixedly connected to one end of the lead screw 209. The servo motor 206 drives the lead screw 209 to rotate. Through the threaded engagement between the lead screw 209 and the slider 208, the rotational motion of the motor is converted into the linear motion of the slider 208, thereby realizing the automated and precise displacement of the transverse plate 202.

[0024] like Figure 5 As shown, a second limiting rod 207 is fixedly connected to the inner wall of the frame 201. The outer wall of the second limiting rod 207 is slidably connected to the inner wall of the slider 208. The sliding connection between the second limiting rod 207 and the slider 208 forms a double guide structure with the lead screw 209. The lead screw 209 is responsible for driving the slider 208 to move, and the second limiting rod 207 limits the slider 208 to slide only along a fixed trajectory.

[0025] like Figure 4 As shown, support legs 203 are fixedly connected to the bottom of the frame 201, and anti-slip pads 204 are fixedly connected to the bottom of the support legs 203. A PLC controller 205 is fixedly installed on the front of the frame 201. The PLC controller 205 enables intelligent operation of the equipment.

[0026] The operation and working principle of this device are as follows: Before use, the operator presets the punching parameters through the control panel on the PLC controller 205. Then, the silicone rubber product to be processed is placed on the transverse plate 202. After starting the equipment, the servo motor 206 drives the lead screw 209 to rotate. Since the thread on the outer wall of the lead screw 209 passes through the inner wall of one of the sliders 208, and the slider 208 is fixedly connected to the transverse plate 202 and slides along the second limiting rod 207 on the inner wall of the frame 201, the rotational motion of the lead screw 209 is converted into the linear motion of the slider 208, thereby driving the transverse plate 202 and the silicone rubber product to be conveyed directly below the changing mechanism 1. At this time, the electric push rod 102 on the top of the connecting plate 101 is activated, driving the lifting plate 103 to move downward. As the lifting plate 103 continues to descend... The punching blade 104 completes the punching operation on the silicone rubber product on the transverse plate 202. After punching, the electric push rod 102 drives the lifting plate 103 and the punching blade 104 to rise. The servo motor 206 starts again, driving the transverse plate 202 to move and transport the punched product to the right side so that the user can take it out. If the punching shape needs to be changed, first disengage the clamping plate 110 from the groove 105, and then apply external force to separate the first magnet 112 from the second magnet 107. The old punching blade 104 can then be removed. When replacing, it is re-fixed by the attraction between opposite poles of the magnets and the clamping action of the clamping plate 110. Production can continue without replacing the entire set of molds, which significantly shortens the product changeover time, reduces mold procurement and maintenance costs, and improves the equipment's adaptability to the production of multiple types of silicone rubber products.

[0027] The PLC controller 205, servo motor 206, and electric actuator 102 used in this application are all common equipment on the market and are well known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. As for their settings, installation, and electrical connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
