[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0035] like Figure 1-10The present embodiment shows a punching device for a metal identification plate, which is suitable for punching small batches of rectangular metal identification plates 6. The punching device includes a base 1, a carrying platform 4, a punching assembly 5 and other components or assemblies. Among them, tracks are installed on the left and right sides of the base 1. The track extends in the front-to-back direction. The aforementioned carrying platform 4 is arranged between the tracks on the left and right sides, and the carrying platform 4 slides with the track so that it can move back and forth on the base 1. The carrying platform 4 moves back and forth on the base 1 to have a material unloading position, a material loading position and a punching position arranged in sequence in the front-to-back direction. When the carrying platform 4 is at the loading position, the metal identification plate 6 can be placed on the carrying platform 4. When the carrying platform 4 is at the punching position, the metal identification plate 6 located on the carrying platform 4 can be punched. When the carrying platform 4 is at the unloading position, the metal identification plate 6 located on the carrying platform 4 can be driven to leave the carrying platform 4. In this embodiment, the unloading position is located at the front side of the base 1, the punching position is located at the rear side of the base 1, and the loading position is located between the punching position and the unloading position.

[0036] A push-pull handle 48 is installed on the carrying platform 4. By holding the push-pull handle 48, the carrying platform 4 can be pushed and pulled to move back and forth between the unloading position, the loading position and the punching position.

[0037] In this embodiment, a limiting area 411 is formed on the aforementioned supporting platform 4. The metal identification plate 6 can be laid flat in the limiting area 411. The limiting area 411 is used to limit the movement of the identification plate to the left and right and to the front. A first limiting member 2 is installed on the base 1 at the front side of the supporting platform 4, and a second limiting member 3 is installed on the rear side of the supporting platform 4. The first limiting member 2 is arranged corresponding to the unloading position, and the second limiting member 3 is arranged corresponding to the punching position. A plurality of first limiting members 2 and second limiting members 3 are arranged side by side in the left-right direction. A first blanking port 11 is arranged on the base 1 corresponding to the unloading position.

[0038] The first avoidance groove 45 and the second avoidance groove 46 extending in the front-to-back direction to the limiting area 411 are processed on the bearing platform 4. Among them, the first avoidance groove 45 is arranged corresponding to the first limiting member 2, the rear end of the first avoidance groove 45 extends to the predetermined position of the limiting area 411, and the front end thereof is open. The second avoidance groove 46 is arranged corresponding to the second limiting member 3, the front end of the second avoidance groove 46 extends to the predetermined position in the limiting area 411, and the rear end thereof is open. The first limiting member 2 is a rod-shaped structure, which is arranged on the front side of the bearing platform 4, and the top of the first limiting member 2 is higher than the limiting area 411. When the bearing platform 4 moves from the rear side of the base 1 toward the unloading position, the first limiting member 2 can enter the first avoidance groove 45 through the front end opening of the first avoidance groove 45, so that it can enter the limiting area 411 relative to the bearing platform 4. The second limiter 3 is a bent structural member formed by bending a thin sheet metal, which is arranged on the rear side of the bearing platform 4, and the top of the second limiter 3 is higher than the limit area 411. When the bearing platform 4 moves from the front side of the base 1 toward the punching position, the second limiter 3 can enter the second avoidance groove 46 through the rear end opening of the second avoidance groove 46, so that it can enter the limit area 411 relative to the bearing platform 4. Through the above-mentioned structural design, at the aforementioned unloading position, the first limiter 2 is accommodated in the first avoidance groove 45, and a disengagement spacing is formed between the first limiter 2 and the rear side of the limit area 411. The disengagement spacing is smaller than the width of the metal identification plate 6, so as to enable the metal identification plate 6 in the limit area 411 to be separated from the bearing platform 4 from the rear side of the limit area 411. In the specific design, the size of the disengagement spacing is smaller than half of the width of the metal identification plate 6. At the aforementioned material discharge position, the first material discharge opening 11 corresponds to the rear side of the limiting area 411 in upper and lower directions, so as to receive the metal identification plate 6 separated from the limiting area 411 .

[0039] When the carrying platform 4 moves to the loading position, the first limiting member 2 and the second limiting member 3 are both away from the limiting area 411 so as not to interfere with the metal identification plate 6 being placed in the limiting area 411 .

[0040] The aforementioned punching assembly 5 is arranged corresponding to the punching position. The punching assembly 5 is a conventional component of the prior art, and is used to punch the identification plate in the limit area 411 at the punching position. Specifically, the punching assembly 5 includes a punching support seat 51, a movable plate 52, a punch 53, a driver 54 and other components. The punching support seat 51 is fixed on the base 1. The movable plate 52 is mounted on the punching support seat 51 so as to be movable up and down through a guide rod. Punches 53 are fixed on the movable plate 52 at the punching positions corresponding to the four corners of the metal identification plate 6. The driver 54 is mounted on the punching support seat 51, and is preferably a hydraulic cylinder or a cylinder. The driver 54 is connected to the movable plate 52 to drive the movable plate 52 to move up and down.

[0041] In this embodiment, the first limiting side plates 42 are arranged on the left and right sides of the limiting area 411 on the carrying platform 4, and the spacing between the two first limiting side plates 42 is adapted to the length of the metal identification plate 6 so as to limit the left and right movement of the metal identification plate 6. The second limiting side plate 43 is arranged on the front side of the limiting area 411 on the carrying platform 4. The second limiting side plate 43 can limit the metal identification plate 6 in the limiting area 411 from moving forward. An extension plate 44 extending to the top of the limiting area 411 is arranged on the top of the aforementioned second limiting side plate 43. An upper and lower plug-in gap is formed between the extension plate 44 and the limiting area 411. When the metal identification plate 6 in the limiting area 411 moves toward the front, it can be inserted into the aforementioned plug-in gap and abut against the second limiting side plate 43. A plurality of spring structures 441 are processed on the aforementioned extension plate 44. The plurality of spring structures 441 are arranged at intervals along the left and right directions. The spring structure 441 is a cantilever structure, which has a fixed end fixedly connected to the extension plate 44, and a spring-pressing end extending from the fixed end toward the rear side. The spring-pressing end of the spring structure 441 extends into the upper and lower plug-in gaps. Through the above-mentioned structural design, when the metal identification plate 6 in the limiting area 411 is inserted into the aforementioned plug-in gap, the metal identification plate 6 is simultaneously inserted under the spring structure 441. The spring structure 441 provides a rebound force to press the metal identification plate 6 down on the supporting platform 4, so that the metal identification plate 6 is placed stably and reliably in the limiting area 411, and there will be no up and down fluctuations during the punching process, which effectively improves the stability of the punching process of the metal identification plate 6.

[0042] The bearing platform 4 of this embodiment includes a bearing base plate 41. The aforementioned limiting area 411 is formed on the bearing base plate 41. The bearing base plate 41, the first limiting side plate 42, the second limiting side plate 43, and the extension plate 44 are integrally formed by sheet metal bending. Specifically, the left and right sides of the bearing base plate 41 are bent upward to form two first limiting side plates 42, the rear side of the bearing base plate 41 is bent upward to form the second limiting side plate 43, and the end of the second limiting side plate 43 is bent toward the rear to form the extension plate 44. The bending angles of the above-mentioned first limiting side plate 42, the second limiting side plate 43, and the extension plate 44 are all 90 degrees.

[0043] In this embodiment, a first receiving plate 13 is fixedly installed on the base 1 below the first material drop opening 11. The first receiving plate 13 has a first receiving surface facing the first material drop opening 11. The first receiving surface is arranged up and down with the inclined upper end of the first receiving surface corresponding to the first material drop opening 11, and the inclined lower end extends toward the front side of the base 1, and forms a gap between the bases 1. The metal identification plate 6 falling through the first material drop opening 11 can be received by the first receiving plate 13, and slide to the front side of the base 1 under the guidance of the first receiving surface, so as to facilitate the operator to take the metal identification plate 6.

[0044] In this embodiment, a second blanking opening 12 is processed on the aforementioned base 1 corresponding to the punching position; a second receiving plate 14 is fixedly installed on the base 1 below the second blanking opening 12. The second receiving plate 14 has a second receiving surface facing the second blanking opening 12. The second receiving surface is arranged up and down with an inclined upper end of the second receiving surface corresponding to the second blanking opening 12, and the inclined lower end extends in the direction of the rear side of the base 1, and forms a spacing between the bases 1. The waste punched by the punching assembly 5 can enter the second blanking opening 12. The punching waste falling through the second blanking opening 12 can be received by the second receiving plate 14, and slide to the rear side of the base 1 under the guidance of the second receiving surface, so as to facilitate the centralized collection of the punching waste. A avoidance hole 47 for avoiding the punch 53 of the punching assembly 5 is processed in the limiting area 411 on the carrying platform 4. During the punching process, the punch 53 enters the avoidance hole 47.

[0045] When in use, the carrying platform 4 is moved to the loading position, and the metal identification plate 6 is placed in the limiting area 411, and the metal identification plate 6 is limited between the two first limiting side plates 42. When the carrying platform 4 is pushed to the rear side to move to the punching position, the second limiting member 3 enters the limiting area 411 through the second avoidance groove 46 to push the metal identification plate 6 in the limiting area 411 to move toward the front side and abut against the second limiting side plate 43 to be limited front and back, and then the metal identification plate 6 is limited and fixed in the limiting area 411 in four directions of front, back, left and right. At the same time, the metal identification plate 6 is inserted under the spring structure 441, and the spring structure 441 provides a rebound force to press the metal identification plate 6 down on the carrying platform 4. The punching assembly 5 is started to complete the punching, and the punching waste generated during the punching process enters the second blanking port 12. After punching is completed, the carrying platform 4 is pulled to move toward the front side, and when it moves to the loading position, the first limiting member 2 enters the limiting area 411 through the first avoidance groove 45 to push the metal identification plate 6 in the limiting area 411 to move toward the rear side and break away from the carrying platform 4 and fall into the first blanking port 11 to realize unloading.
