DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a punching machine that is easy to clean, including a punching machine body 1, a punching head 101 is fixedly connected to the punching machine body 1, a fixed platform 2 is slidably installed on the punching machine body 1, a slide rail 102 is symmetrically fixedly connected to the front of the punching machine body 1, and a slider 203 is symmetrically fixedly connected to the bottom of the fixed platform 2. The slider 203 slides with the slide rail 102, and a rotating shaft 3 is rotatably installed on one side of the fixed platform 2. A limit block 303 is fixed on the rotating shaft 3, and a limit plate 4 is fixedly connected to one side of the punching machine body 1. Two limit slots 401 are provided on the limit plate 4, and the limit slots 401 cooperate with the limit block 303. A collection box 5 is placed in front of the punching machine body 1.

[0022] In this embodiment, the slider 203 slides with the slide rail 102, and the rotating shaft on the side of the slider 203 can slide inside the slide rail 102. The slider 203 is located at the center of the bottom of the fixed table 2. At this time, the front and rear centers of the fixed table 2 are balanced, which facilitates the rotation of the fixed table 2. After the fixed table 2 is moved to the front end, the slider 203 rests on the end of the slide rail 102. At this time, the fixed table 2 can rotate to a certain angle, such as Figure 3As shown, at this time, the waste chips on the fixed table 2 can be directly dumped into the collection box 5 for collection, which is convenient for cleaning the waste chips generated by stamping. At the same time, the limit card block 303 cooperates with the limit card slot 401. After the limit card block 303 is inserted into the limit card slot 401, the forward and backward movement of the fixed table 2 can be restricted. There are two limit card slots 401, which are respectively corresponding to the fixed table 2 located below the punching head 101. Figure 1 As shown, the fixing platform 2 moves forward and out from under the punching head 101, as shown in FIG. Figure 2 As shown, at this time, the slider 203 is not completely at the end of the slide rail 102. A part of the front end of the slide rail 102 will support the fixed table 2, thereby limiting the rotation of the fixed table 2. At this time, the fixed table 2 is moved out from under the punch head 101. First, there is more space, which is convenient for the operator to place and remove the workpiece. Secondly, it is staggered with the punch head 101, which can effectively avoid the problem of accidental start-up of the punch head 101 and causing serious safety accidents.

[0023] Among them, in order to achieve the purpose of sliding the fixed platform 2 on the punching machine body 1, this device adopts the following technical solution: a slide groove 103 is opened on the punching machine body 1, the slide groove 103 slides with the slider 203, the upper mold is fixedly connected to the bottom of the punching head 101, and the stamping lower mold 201 is fixedly connected to the top of the fixed platform 2.

[0024] By cooperating with the slide groove 103, the slide rail 102 and the slider 203, the fixed table 2 can be moved forward a certain distance, the workpiece is placed on the stamping lower die 201, and the punch head 101 is used to drive the upper die downward to stamp the workpiece.

[0025] Among them, in order to achieve the purpose of making the limit block 303 be stuck in the limit slot 401, this device adopts the following technical solution: a displacement handle 202 is fixedly connected to the front of the fixed platform 2, an interference block 204 is fixedly connected to one side of the fixed platform 2, a spring connecting piece 301 is fixedly connected to the rotating shaft 3, a torsion spring 302 is sleeved on the rotating shaft 3, one end of the torsion spring 302 is fixedly connected to the spring connecting piece 301, and the other end of the torsion spring 302 is fixedly connected to the side of the fixed platform 2, and a rotating handle 304 is fixedly connected to the rotating shaft 3.

[0026] The displacement handle 202 is used to facilitate pulling the fixed platform 2 to move, and the interference block 204 and the rotating handle 304 interfere with each other, limiting the rotation of the rotating shaft 3 for one circle, causing the torsion of the torsion spring 302 to be released. The torsion spring 302 can provide a certain torsion for the spring connecting piece 301. The spring connecting piece 301 will drive the rotating shaft 3 to rotate under the torsion, and the rotation of the rotating shaft 3 will cause the limiting block 303 to rotate, so that the limiting block 303 is stuck in the limiting slot 401, and the rotating handle 304 can be used to drive the rotating shaft 3 to rotate.

[0027] The working principle and use process of the present invention are as follows: when in use, it is first necessary to use the rotating handle 304 to drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 will drive the limit card block 303 to rotate out of the limit card slot 401, thereby releasing the restriction on the fixed platform 2. At this time, the displacement handle 202 can be used to drive the fixed platform 2 to move forward. Since the torsion spring 302 continuously provides torque for the rotating shaft 3, when the limit card block 303 moves to another limit card slot 401, the torsion spring 302 pushes the limit card block 303 to automatically snap into the other limit card slot 401, thereby fixing the position of the fixed platform 2 again. Figure 2 As shown, at this time, the fixed table 2 and the punching head 101 are horizontally offset. The operator can place the workpiece on the stamping lower die 201, repeat the above operation to reset the fixed table 2, start the punching head 101 to stamp the workpiece, and move the fixed table 2 forward after the stamping is completed. After the stamping is completed, the fixed table 2 is taken out and the fixed table 2 is continued to be moved forward so that the slider 203 is at the front end of the slide rail 102. At this time, the fixed table 2 can be rotated to a certain angle, and the waste chips on the fixed table 2 can be dumped into the collection box 5.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
