DETAILED DESCRIPTION

[0041] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or there can be one or more centered elements therebetween. The terms "upper", "lower", "left", "right", "upper end", "lower end", "top" and "bottom" used in this specification indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] In the prior art, the gap between the upper and lower rubber rollers for pressing the flexible board is small, and it is inconvenient to manually insert the starting end of the flexible board into the gap. The efficiency is low and the unevenness of the surface of the flexible board is easily aggravated during the loading process, thereby affecting the efficiency and quality of punching. In order to solve the above problems, the utility model provides a co-position pressing device and a punching machine.

[0044] The following will be combined with the Figures 1 to 8 A co-position pressing device and a punching machine provided in an embodiment of the utility model are described in detail.

[0045] See also Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of a co-position pressing device of the utility model. Figure 2 This is the first exploded view of a co-location pressing device of the present invention.

[0046] A co-position pressing device, comprising:

[0047] The mounting plate 1 is provided with a rotating hole 11 and a riveting hole 12. The riveting hole 12 is located above the rotating hole 11.

[0048] The connecting plate 2 includes an abutting portion 21 and a connecting portion 22. The abutting portion 21 includes an upper side edge 211 and a lower side edge 212. The upper side edge 211 is recessed inward relative to the lower side edge 212. The connecting portion 22 includes a connecting area 221 and a protruding area 222. The connecting area 221 is raised on the surface of the abutting portion 21, and the protruding area 222 protrudes from the side of the abutting portion 21. The protruding area 222 is correspondingly provided with a mounting hole 2221. The connecting portion 22 is nested in the rivet hole 12 to cooperate with the connecting plate 2 and the mounting plate 1.

[0049] The support rod 3 is rotatably mounted on the rotating hole 11;

[0050] The pressure rod assembly 4 includes a pressure rod 41, a rotating member 42 and a fixed shaft 43. Upper rotation holes 421 and lower rotation holes 422 are provided at both ends of the rotating member 42. One end of the fixed shaft 43 is fixedly connected to the mounting hole 2221, and the other end can be rotatably mounted in the upper rotation hole 421. The end of the support rod 3 can be rotatably nested in the lower rotation hole 422. The pressure rod 41 and the rotating member 42 can be rotated around the fixed shaft 43 from a first position to a second position and abut against the abutment 21, or rotated from the second position to the first position. The first position is above the support rod 3, and the second position is the upper side edge 211 of the abutment 21. A gap is provided between the first position and the support rod 3 for squeezing the flexible plate through.

[0051] Specifically, the supporting rod 3 and the pressing rod 41 include rubber rollers, the supporting rod 3 is the lower rubber roller, and the pressing rod 41 is the upper rubber roller. In the prior art, the upper and lower rubber rollers are fixedly arranged and their relative positions are also fixed. A gap is set between the upper and lower rubber rollers for the flexible plate to pass through. After manually inserting the starting end of the flexible plate into the gap, the flexible plate is pulled forward and the starting end of the flexible plate is wound on the reel of the driving mechanism. The starting end of the flexible plate is rolled by the driving mechanism, and then the flexible plate is pulled forward by rolling friction in the gap between the upper and lower rubber rollers. The upper and lower rubber rollers squeeze the flexible plate to reduce the concave and convex points and concave and convex areas of the flexible plate. Since the relative positions of the upper and lower rubber rollers are fixed, the gap between them cannot be changed. When it is necessary to pass the starting end of a roll or a sheet of flexible plate through the gap, the manual filling efficiency is low, and it will also aggravate the unevenness of the surface of the flexible plate, thereby causing uneven force on the workpiece and affecting the punching quality. If the fixed position relationship between the upper and lower rubber rollers is changed to a changeable position relationship, the size of the gap can be adjusted. When the starting end of a roll or a sheet of flexible board needs to be passed through the gap, the gap is first increased, and the surplus of the starting end of the flexible board is passed through the increased gap and wound on the reel of the driving mechanism. At this time, the flexible board has contacted the rubber roller below, and then the upper rubber roller is adjusted to its original position to generate pressure on the flexible board. The driving mechanism pulls the flexible board forward, and then the concave and convex points and concave and convex areas of the flexible board are squeezed by the upper and lower rubber rollers to be flat, thereby improving the punching quality.

[0052] The operation process is as follows: when the starting end of the flexible plate needs to be inserted into the gap, the pressure rod assembly 4 is rotated from the first position to the second position, abutting against the upper edge 211 of the abutting portion 21, and the surplus of one end of the flexible plate is placed on the supporting rod 3. The pressure rod assembly 4 is rotated from the second position to the first position to press the flexible plate. During the rotation process, the rotating member 42 and the pressure rod 41 rotate around the fixed axis 43. Compared with the process of manually inserting the starting end of the flexible plate into the gap in the prior art, this process greatly improves the punching efficiency, avoids aggravating the unevenness of the flexible plate surface, makes the workpiece evenly stressed, and improves the punching quality.

[0053] See also Figure 2 and Figure 3 , Figure 3 This is a schematic diagram of the three-dimensional structure of a mounting plate 1 of a co-position pressing device of the present invention.

[0056] Specifically, the support rod 3 and the pressure rod assembly 4 have two ends, and the first mounting plate 14 and the second mounting plate 15 can be symmetrically set at the two ends to support the support rod 3 and the pressure rod assembly 4, so as to quickly adjust the relative position between the pressure rod assembly 4 and the support rod 3, and then adjust the distance of the gap, so that the starting end of the flexible plate can quickly pass through the adjusted gap and be wound on the reel of the driving mechanism, thereby improving the punching efficiency.
