Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of punching devices, and in particular relates to a punching device for sign processing. Background Technology
[0002] Metal signs are widely used for road guidance, safety warnings, and public information dissemination. To meet the needs of different application scenarios, signs require a series of processing steps during production, including drilling holes in specific locations for installation or other functional purposes. Traditional sign punching equipment typically uses fixed molds or simple limiting seats to support and position the signs to be processed, ensuring that the punching operation is performed accurately in the preset positions.
[0003] For example, according to publication number CN220681037U, titled "A punching device for sign production," it includes a worktable, a punching assembly disposed on the worktable, and a positioning member disposed on the worktable. The positioning member has a positioning surface, and the corner of the sign abuts against the positioning surface to achieve positioning of the required punching position at the corner of the sign.
[0004] The aforementioned patent has some defects in the sign punching equipment: when the sign is placed on the positioning part to prepare for punching, the positioning part is designed only to fit the outline of the sign and fails to provide effective positioning function in the vertical direction. This may cause the sign to shift slightly or vibrate during the punching process, thereby affecting the punching accuracy and possibly causing scrap. Utility Model Content
[0005] The purpose of this utility model is to provide a punching device for sign processing, so as to solve the technical problem of not being able to position signs as mentioned in the background art.

[0008] Preferably, a limiting plate is fixed on the outer peripheral surface of the punching rod, and symmetrical grooves are provided on both sides of the outer peripheral surface of the punching rod. A lower pressure plate for pressing and positioning is sleeved on the outer peripheral surface of the punching rod, and one end of the slider fixed on the inner ring wall of the lower pressure plate extends into the groove.
[0009] Preferably, a spring is sleeved on the outer circumferential surface of the punched rod between the lower pressure plate and the limiting plate.
[0010] Preferably, the positioning component is formed by a slot formed inward on the surface of the card holder, and the depth of the slot is sufficient to engage the signboard inside, so as to prevent the signboard from tilting or shifting upward.
[0011] Preferably, the positioning component is composed of an electromagnet inside the limiting seat, and a slot is provided inside the limiting seat to house the electromagnet.
[0012] Preferably, the positioning component consists of an adsorption hole on the surface of the limiting seat and an air pump, and an air suction chamber is provided inside the limiting seat, with the adsorption hole and the air suction chamber communicating with each other.

[0030] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a punching device for processing nameplates.
[0031] like Figures 1-2 As shown, the present invention discloses a punching device for processing signs. Its main technical content includes a base frame 1 with a flat top surface. A hydraulic press 13 for providing power for punching can be connected above the base frame 1. The hydraulic press 13 is fixedly connected to a top frame 12 fixedly connected above the base frame 1. The output end of the hydraulic press 13 passes through one side of the top frame 12. At the same time, a punching base 131 is fixed at its free end. The punching base 131 moves up and down as the hydraulic press 13 runs.
[0032] A punching rod 132 is fixed to the bottom surface of the stamping base 131. A limiting seat 2 is fixed to the surface of the base frame 1 below the punching hole of the punching rod 132. The punching rod hole 21, which is opened through the surface of the limiting seat 2, is coaxially opposite to the punching rod 132. The waste material falling through the punching rod hole 21 is discharged through the discharge pipe 11 connected to the bottom of the base frame 1. At the same time, a retaining seat 22 is fixed at the upper edge of the limiting seat 2. The retaining seat 22 can limit the forward displacement of the sign.
[0033] like Figure 9 As shown, a limiting plate 133 is fixed to the upper part of the outer peripheral surface of the punching rod 132, and symmetrical grooves 134 are provided on both sides of the outer peripheral surface of the punching rod 132. A pressing plate 135 for pressing and positioning is sleeved on the outer peripheral surface of the punching rod 132, and one end of the slider fixed to the inner ring wall of the pressing plate 135 extends into the groove 134. A spring 136 is sleeved on the outer peripheral surface of the punching rod 132 between the pressing plate 135 and the limiting plate 133. Therefore, when the sign needs to be punched, the punching rod 132 moves downward through the hydraulic press 13. After the bottom surface of the pressing plate 135 contacts the surface, the punching rod 132 continues to punch and press down, thereby enabling the pressing plate 135 to press down on the surface of the sign, achieving the effect of pressing and positioning.
[0034] like Figure 3 As shown, the main technical content of the first specific embodiment is illustrated. In the first embodiment, the main technical solution includes a positioning component on the limiting seat 2 for limiting the upward tilting of the sign. This positioning component is composed of a slot 221 formed inward on the surface of the slot 22. The depth of the slot 221 allows the sign to be engaged internally to prevent displacement of the sign during upward tilting.
[0035] like Figures 4-5 As shown, the main technical content of the second specific embodiment is illustrated. Although it maintains the same core design concept as the first embodiment, the positioning component has been improved. The positioning component is composed of an electromagnet 231 inside the limiting seat 2. A slot 23 is provided inside the limiting seat 2 to place the electromagnet 231. The opening and closing of the electromagnet 231 is achieved by a switch. After the sign is placed above the limiting seat 2, the switch is pressed to turn on the power. At this time, the electromagnet 231 runs and attracts the sign, thereby attracting and fixing the sign to the surface of the limiting seat 2 to prevent the sign from tilting or shifting upwards.
[0036] like Figures 6-8As shown, the main technical content of the third specific embodiment is illustrated. The positioning component consists of an adsorption hole 3 on the surface of the limiting seat 2 and an air pump 33. An air suction chamber 31 is provided inside the limiting seat 2, and the adsorption hole 3 communicates with the air suction chamber 31. The air pump 33 is fixed to one side of the surface of the base frame 1, and the air suction inlet of the air pump 33 is connected to the air suction chamber 31 through a suction pipe 32. Therefore, when the sign needs to be punched, the sign is placed above the limiting seat 2, and then the air pump 33 operates, adsorbing and fixing the sign through the suction pipe 32 and the adsorption hole 3, thereby allowing the sign to be adsorbed and fixed on the surface of the limiting seat 2 to prevent the sign from tilting upwards and shifting during punching.
[0037] like Figures 6-9 As shown, an exhaust pipe 331 is connected to the exhaust end of the vacuum pump 33, and an air blowing chamber 4 is provided inside the punching rod 132. The interior of the air blowing chamber 4 communicates with one end of the exhaust pipe 331, and an air blowing hole 41 opened on the bottom surface of the punching rod 132 communicates with the interior of the air blowing chamber 4. Therefore, when the vacuum pump 33 is running, the gas discharged from its exhaust end is blown into the air blowing chamber 4 through the exhaust pipe 331 and blown out from the air blowing hole 41, thereby achieving dust removal treatment on the surface of the sign before punching the punching rod 132.
[0038] The working principle of a punching device for sign processing: When a sign needs to be punched, the sign can be placed above the limiting seat 2. Then, the sign can be pre-positioned by the positioning component to prevent displacement during the punching process. After the pre-positioning, the punching rod 132 moves downward through the hydraulic press 13. After the bottom surface of the pressure plate 135 contacts the surface, the punching rod 132 continues to punch and press down, thereby enabling the pressure plate 135 to press down on the surface of the sign, achieving the effect of pressing and positioning.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
