Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat insulation cover production technology, specifically a heat insulation cover punching device. Background Technology
[0002] For heat shields in automotive exhaust systems, the heat shield material is relatively soft and easily deformed, with strong ductility, making it difficult to form in one piece using molding dies. In addition, the heat shield has various cavities of different specifications, sizes, and positions. For continuous production of the heat shield, multiple punching machines and different dies are required, resulting in low processing efficiency. Furthermore, multiple control components such as hydraulic cylinders are needed, which is not conducive to precise control.
[0003] Patent application CN115958651A discloses a continuous punching device for heat insulation covers, including a base plate, a cutting roller, several die holders, a set of slides, and a forming seat. The base plate has a positioning opening, and the forming seat is fixed within the positioning opening with a clearance fit. A set of slides is fixed on both sides of the top of the base plate, and a stamping cylinder is fixed to the top of each slide. A slider is rotatably connected to the shaft end of the cutting roller via bearings. The sliders at both ends of the cutting roller are slidably disposed within the two slides. The top of the slides is fixed to the output end of the stamping cylinder via a connecting frame. This invention, by designing a rotatable cutting roller with precisely controllable angles, can automatically and quickly switch the cutting dies on the cutting roller. All cutting dies share the same set of stamping cylinders for centralized processing and forming, resulting in lower costs and easier precise control, facilitating continuous punching of holes in the heat insulation cover.
[0004] However, in practical applications, traditional punching devices are prone to causing the heat shield to warp during punching due to the large impact force on the heat shield. Since one end of the heat shield is simply placed on the forming seat and there is no device to fix and clamp the heat shield, the heat shield is easily warped, which affects the punching accuracy. Therefore, it needs to be improved. For example, when the worker places the heat insulation cover to be processed on the forming seat and the cutting roller presses down to process it, since there is no device to fix and clamp the heat insulation cover, the heat insulation cover is subjected to a large impact force during punching, which can easily cause the heat insulation cover to shift or lift up, thus affecting the punching accuracy. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a heat insulation cover punching device to solve the technical problem that the heat insulation cover is subjected to a large impact force during punching, and one end of the heat insulation cover is simply placed on the forming seat without a device to fix and clamp the heat insulation cover, which easily leads to the heat insulation cover lifting up.
[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a heat insulation cover punching device is designed, including a base plate, a cutting roller and a limiting plate. A forming seat is provided on the base plate, and a forming hole is provided through the forming seat. Slide seats are fixedly connected to the top two sides of the base plate. A stamping cylinder is fixedly connected to the top of the slide seats. A top plate is fixedly connected to the output end of the stamping cylinder. Two vertical rods are fixedly connected to the bottom of the top plate. A slider is fixedly connected to the bottom end of one vertical rod, and a mounting seat is fixedly connected to the bottom end of the other vertical rod. The slider is rotatably connected to the cutting roller through a bearing. Limiting plates are fixedly connected to both ends of the bottom of the cutting roller.
[0007] In this solution, the cutting roller is driven by the stamping cylinder to move horizontally and vertically, which makes it easier for the cutting die directly below the cutting roller to pass through the corresponding forming holes on the heat insulation cover and the forming seat in sequence, thereby improving processing efficiency.
[0008] Preferably, an internal gear ring is fixed at one end edge of the die-cutting roller, and a gear is externally meshed with the internal gear ring. A drive motor is fixedly connected to the top of the mounting base, and the input end of the gear is fixedly connected to the drive motor.
[0009] In practical applications, the gear is driven by a drive motor to rotate, and the gear meshes with the internal gear ring to rotate, which facilitates the rotation of the cutting roller and allows for precise angle control.
[0010] Preferably, the peripheral side of the cutting roller is annular and evenly spaced with a plurality of sliding grooves, the sliding grooves being convex grooves, a sliding strip being slidably connected in the sliding groove, and a mold base being fixedly connected to the top of the sliding strip.
[0011] In practical applications, the combination of chutes and slide bars allows for automated and rapid switching of the cutting molds on the cutting rollers, resulting in high processing efficiency, low cost, and precise control.
[0012] Preferably, the outer side of the mold base is a flat surface, and two rows of mounting holes are provided on the outer side of the mold base. A cutting mold is fixed to the outer side of the mold base through the mounting holes.
[0013] In practical applications, the cutting die can be quickly installed and removed from the outside of the cutting roller, which facilitates the replacement and maintenance of the cutting die and has a wide range of applications.
[0014] Preferably, a threaded rod is rotatably mounted inside the limiting plate. One end of the threaded rod is fixedly connected to a handle, and the other end of the threaded rod is provided with a connector. A spring is provided inside the connector. A clamping plate is fixedly connected to the end of the connector away from the handle, and a pad is fixedly connected to the outside of the clamping plate.
[0015] In practical applications, the heat insulation cover can be limited by the limiting plate, threaded rod and clamping plate. Turning the handle drives the threaded rod to rotate and pushes the clamping plate to both ends of the heat insulation cover to limit it.
[0016] Preferably, a guide rail is fixedly connected to the top of the base plate, a slide block is slidably connected to the outside of the guide rail, and an abutment block is fixedly connected to the side wall of the slide block.
[0017] In practical applications, the guide rail and slide block work together to facilitate the partitioning of heat insulation covers of different lengths, thereby reducing the possibility of force displacement.
[0018] Preferably, a threaded cylinder is fixedly connected to the top of the slide block, a positioning plate is sleeved on the outside of the threaded cylinder, an anti-slip pad is fixedly connected to the bottom of the positioning plate, and a nut is rotatably connected to the top of the threaded cylinder.
[0019] In practical applications, the vertical position of the positioning plate can be adjusted using a threaded cylinder and a nut, so that the positioning plate can better block heat insulation covers of different thicknesses, and reduce the possibility of the heat insulation cover shifting under force during punching.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can limit the heat insulation cover by combining a limiting plate, a threaded rod and a clamping plate. The rotation of the threaded rod drives the clamping plate to block and limit the two ends of the heat insulation cover, which can reduce the possibility of the heat insulation cover shifting under force during punching.
[0021] 2. This utility model, through the combination of a threaded cylinder and a nut, can adjust the vertical position of the positioning plate so that the positioning plate can better block heat insulation covers of different thicknesses. Attached Figure Description

[0025] For details, see Figures 1 to 5 An internal gear ring 210 is fixed at one edge of the cutting roller 200. A gear 220 is meshed with the internal gear ring 210. A drive motor 221 is fixedly connected to the top of the mounting base 150. The input end of the gear 220 is fixedly connected to the drive motor 221.

The drive motor 221 drives the gear 220 to rotate, and the gear 220 meshes with the internal gear ring 210 to rotate, which facilitates the rotation of the cutting roller 200 and allows for precise angle control. Through the cooperation of the slide groove 230 and the slide bar 240, the cutting mold on the cutting roller 200 can be automatically and quickly installed and removed. This method has high processing efficiency, low cost, and is conducive to precise control. It also facilitates the replacement and maintenance of the cutting mold and has a wide range of applications.
[0026] Further, see Figures 1 to 5 A threaded rod 310 is rotatably mounted inside the limiting plate 300. One end of the threaded rod 310 is fixedly connected to a handle 320. The other end of the threaded rod 310 is externally provided with a connector 330. A spring 340 is provided inside the connector 330.

[0027] In practical application, this solution works as follows: Based on the required opening shape and specifications of the heat insulation cover, the operator selects the corresponding cutting die and installs it on the outside of the die base 250 through the mounting port 251. Then, the heat insulation cover to be processed is placed on the forming seat 110.

This results in high processing efficiency, low cost, and precise control, while also facilitating the replacement and maintenance of the cutting die. It has a wide range of applications. The heat insulation cover can be limited by the limiting plate 300, the threaded rod 310 and the clamping plate 350. Rotating the handle 320 drives the threaded rod 310 to rotate and push the clamping plate 350 to both ends of the heat insulation cover for limiting.
