as shown in fig. 1-4, the utility model provides a splint machine, which comprises an operating platform 1 provided with a bracket 2, a hydraulic cylinder 3 fixed on the bracket 2, a pressing plate 5 and a cutter plate 6; the end part of a piston rod of the hydraulic cylinder 3 is provided with a connecting plate 4, the cutter plate 6 is fixed on the connecting plate 4, the pressing plate 5 is attached to the cutter plate 6, the lower end of the pressing plate 5 is lower than that of the cutter plate 6, and one side, attached to the cutter plate 6, of the pressing plate 5 is flush with the edge of the operating table 1; the guide rod 51 is vertically arranged between the pressing plate 5 and the connecting plate 4, one end of the guide rod 51 is fixed on the connecting plate 4, the other end of the guide rod 51 is connected in the pressing plate 5 in a sliding mode, the guide rod 51 is further sleeved with a compression spring 52, and two ends of the compression spring 52 are fixed on the connecting plate 4 and the pressing plate 5 respectively.

According to the above technical scheme, the utility model discloses a technical thought does: through clamp plate 5 and cutter board 6 respectively elastic connection on connecting plate 4, realize that a pneumatic cylinder 3 is to pressing earlier of panel and cut afterwards.

Preferably, the cutter plate 6 is fixed with a lifting rod 61, and the pressure plate 5 is provided with a strip hole 53 for the sliding of the lifting rod 61. The lifting rod 61 is perpendicular to the cutter plate 6 and the pressing plate 5, the pressing plate 5 penetrates through the strip hole 53, one end of the lifting rod is fixed on the cutter plate 6, and the end of the lifting rod 61 is provided with a nut, so that the pressing plate 5 is convenient to disassemble and overhaul. The lifting rod 61 is arranged so that when the piston rod of the hydraulic cylinder 3 is lifted, the pressure plate 5 can be lifted upwards by the lifting rod 61, rather than by the elastic force of the compression spring 52. Further, the compression spring 52 is always compressed to a certain degree, and does not expand or contract and shake, thereby ensuring the stability of the whole pressing plate 5.

Preferably, the pressing plate 5 and the cutter plate 6 are also slidably connected to the bracket 2 along the vertical direction, and the bracket 2 is provided with a sliding groove for the pressing plate 5 and the cutter plate 6 to slide. The movable directions of the pressing plate 5 and the cutter plate 6 are limited through the sliding grooves, so that the positions of the pressing plate 5 and the cutter plate 6 in the pressing process are more accurate.

Preferably, both sides of the cutter plate 6 are provided with side plates 62, the side surface of the operating platform 1 is provided with a contact switch 7, and the contact switch 7 is positioned below the side plates 62. The matching between the cutter plate 6 and the slide rail is also realized through the side plate 62, and the contact switch 7 comprises a supporting seat 72, an expansion rod 74 and a contact piece 71; the telescopic rod 74 is connected in the supporting seat 72 in a sliding manner, the contact piece 71 is positioned at the upper end of the telescopic rod 74, an extension spring 73 is sleeved outside the telescopic rod 74, and two ends of the extension spring 73 are respectively fixed on the contact piece 71 and the supporting seat 72; the lower end of the telescopic rod 74 is provided with a disc-shaped bulge, and a cavity 75 for the bulge to slide is arranged in the supporting seat 72. When the side plate 62 descends along with the tool plate 6, the side plate firstly contacts with the contact piece 71, the hydraulic cylinder 3 stops working, but the stopping is not realized immediately, the hydraulic rod can slide downwards for a little distance and can not be blocked by the contact piece 71, therefore, the contact piece 71 is connected in a sliding mode in the vertical direction, the contact piece 71 is supported by the telescopic spring 73, the telescopic rod 74 plays a guiding role, and the telescopic spring 73 is prevented from being laterally deviated due to long-term working.

Preferably, a material baffle plate is arranged in front of the cutter plate 6 along the feeding direction, and the material baffle plate is detachably fixed on the side plate 62. Through setting up the striker plate, can guarantee to cut equally many parts at every turn, also can be used to batch production. The striker plate can be detachably connected with the side plate 62 through the extension arm on the side, and different lengths can be cut by changing the length of the extension arm. The extension arms are positioned at two sides of the cutter plate 6 and are not positioned on the moving path of the cutter plate 6, so that the cutter plate is prevented from being damaged or the cut plates are prevented from falling.

It should be noted that two or more compression springs 52 are used in conjunction with the guide rods 51 to ensure that the pressure plate 5 is not prone to tilting during depression. Even can guarantee that the panel width is less, the horizontal degree of the lower pressure face of clamp plate 5 is also higher, and clamp plate 5 descends the in-process and is difficult for blocking. The matching between the lifting rod 61 and the bar hole 53 can be two or more, so that the lifting rod is not easy to be blocked when being lifted. The side plate 62 extends to some extent at the inner side of the contact switch 7, so that the contact switch 7 is shielded by the side plate 62, and the cut plate cannot be touched by mistake. The tool is mounted with a small spacing and inclination and does not touch the table 1. When the device works, the hydraulic cylinder 3 is pressed downwards, the pressing plate 5 is firstly contacted with the plate, in the process of continuously pressing downwards, the compression spring 52 is compressed, the pressing plate 5 is pressed against the plate by the force of the compression spring 52, and then the plate is cut by the shearing plate to fall on a storage or conveying device below.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will understand that the present invention can be modified or replaced with other embodiments without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
