Description

Technical Field

[0001] The utility model relates to a punching device for elevator accessories, in particular to a punching device for elevator accessories used in the field of punching devices. Background Art

[0002] Elevator accessory punching devices are specialized equipment used to punch holes in elevator accessories (such as elevator car siding, door panels, handrails, etc.). The power system is the core power source of the punching device. Two common types of power are hydraulic and mechanical. The hydraulic power system uses a hydraulic pump to pressurize the hydraulic oil, driving the piston of the hydraulic cylinder to generate a strong punching force. This power method features high pressure and uniform punching force, making it suitable for punching thicker materials. Mechanical power systems utilize motors to drive mechanical structures such as crankshafts and connecting rods, converting rotational motion into an upward and downward punching motion. The advantages of mechanical power systems are high speed and efficiency, making them suitable for batch punching.

[0004] The existing elevator accessory punching device lacks an effective support and protection mechanism for the processing of long accessory strips. When the workpiece length exceeds a certain range, due to the lack of a specially designed supporting structure, the workpiece is very likely to bend downward near the punching area under the action of its own gravity. Especially in the continuous punching process, as the number of punching points increases, this deformation becomes more and more significant, which not only makes it difficult to ensure the accuracy of the punching position, resulting in the inability to accurately match the hole position with other components during subsequent assembly, but may also cause internal stress concentration in the material due to workpiece deformation, reducing the mechanical properties and service life of the accessories. Utility Model Content

[0005] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that the existing elevator accessories punching device lacks an effective support and protection mechanism for the processing of long-sized accessory strip workpieces.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-6 A punching device for elevator accessories is shown, comprising a punching equipment body 1, a lower mold 2 is provided at the upper end of the punching equipment body 1, an upper mold 3 is connected to the upper end of the lower mold 2, an accessory strip workpiece 5 is placed between the lower mold 2 and the upper mold 3, a supporting follower base plate 6 is provided at the left end of the lower mold 2, and the end of the supporting follower base plate 6 away from the punching equipment body 1 is fixedly connected to the abutting protruding horizontal bar 7, a strip-shaped opening blanking groove 11 is provided in the middle of the supporting follower base plate 6, a pair of self-rebounding hinges 12 are installed on the rear inner wall of the strip-shaped opening blanking groove 11, and self-resetting bottom opening plates 8 are installed on the outer ends of the two self-rebounding hinges 12, and mutually synchronized telescopic connecting sleeves 13 are provided at the middle position of the self-resetting bottom opening plate 8 and the supporting follower base plate 6, a pair of transverse spring connectors 16 are fixedly connected to the left end of the lower mold 2, and lower protruding columns 15 are symmetrically fixedly connected to the front and rear ends of the lower end of the abutting protruding horizontal bar 7.

[0027] Figure 1-6 It is shown that the two lower protruding columns 15 and the transverse spring connecting member 16 are connected to each other correspondingly. The transverse spring connecting member 16 is located directly below the supporting follower base plate 6. The lower end of the upper mold 3 is fixedly connected to the hydraulic drive member 9. The accessory strip workpiece 5 moves to directly above the self-resetting bottom opening plate 8. The output end of the hydraulic drive member 9 is fixedly connected to the punching head 10. The upper end of the lower mold 2 is provided with a blanking knife groove 14. The blanking knife groove 14 is located directly below the punching head 10. The accessory strip workpiece 5 passes through the position between the punching head 10 and the blanking knife groove 14. The self-resetting bottom opening plate 8 and the strip-shaped opening blanking groove 11 match each other. The end of the accessory strip workpiece 5 away from the punching equipment body 1 abuts against the abutting protruding horizontal bar 7.

[0028] Figure 1-6It is shown that in the operation process of this scheme, the accessory strip workpiece 5 passes through the area between the punching head 10 and the blanking knife groove 14 inside the punching equipment body 1, and the hydraulic drive part 9 stably drives the punching head 10 to press vertically downward to perform the punching operation on the accessory strip workpiece 5. After the punching is completed, the waste generated slides down the blanking knife groove 14 to the corresponding waste collection tank by gravity, ensuring the cleanliness of the processing area and avoiding the accumulation of waste to interfere with the subsequent punching operation. At the same time, the accessory strip workpiece 5 is pushed at a uniform speed by the external drive device.
