Detailed Description

To explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following detailed description is made with reference to the accompanying drawings. The upper, lower, left, right, front and rear positional relationships described in this embodiment correspond to the positional relationships shown in fig. 1, respectively. The transverse direction refers to a direction extending from left to right.

As shown in fig. 1 to 5, the hot-sheet transverse cutting device is mainly used for cutting a hot sheet extruded from an outlet 31 of a forming die 3, and includes a cutting mechanism 1 and a lifting mechanism 2. Specifically, the cutting mechanism 1 includes a plurality of blades 11 and a cutting drive assembly 12. The lifting mechanism 2 comprises a lifting frame 21 and a lifting driving assembly 22 which are fixedly arranged on the forming die 3, the cutting mechanism 1 can be arranged on the lifting frame 21 along the up-down direction, and the lifting driving assembly 22 is used for driving the cutting mechanism 1 to move. Referring to fig. 6 and 7, the cutting driving assembly 12 includes a tool post 121 disposed on the crane 21 and capable of moving in an up-and-down direction, a driving sprocket 122 and a driven sprocket 123 mounted on the tool post 121, a chain 124 connected between the driving sprocket 122 and the driven sprocket 123 and arranged in a transverse direction, and a motor 125 mounted on the tool post 121 and in transmission connection with the driving sprocket 122, wherein a plurality of blades 11 are fixedly disposed on the chain 124 and extend in the up-and-down direction. As shown in fig. 3, 4 and 8, the lifting frame 21 is fixedly provided with a guide rail 211 extending up and down, and the tool post 121 is slidably connected to the guide rail 211. The lifting driving component 22 is a cylinder fixed on the lifting frame 21, and one end of a piston rod of the cylinder is fixedly connected with the tool rest 121. As shown in fig. 2 and 5, the plurality of blades 11 are arranged at equal intervals along the length direction of the chain 124. In order to facilitate the sheet material to be cut by the plurality of blades 11 before the sheet material is cut, cutting efficiency is improved, and it is more convenient to cut a wide sheet material. As shown in fig. 7, each blade 11 has a cutting edge portion 111 at one end and cutting edge portions 112 at opposite sides.

Since the chain 124 is long and is likely to shake during movement, in order to reduce the shaking of the chain 124 during movement, a plurality of limit baffles 126 are arranged on the tool holder 121 at equal intervals in the transverse direction, and each limit baffle 126 has a limit groove 1261 through which the chain 124 passes. Thus, when the chain 124 is circularly reciprocated in the lateral direction, the chain is limited in the limiting groove 1261 by the limiting baffle 126, so that the shaking of the chain 124 can be reduced as much as possible, the cut of the sheet can be ensured to be orderly when the sheet is cut, and the product quality can be improved.

The working principle of the utility model is as follows: the hot sheet is extruded from the outlet 31 side of the forming die 3, when the length of the sheet reaches the process requirement, the cylinder drives the knife rest 121 to move downward integrally, so that the plurality of blades 11 are inserted into the hot sheet, then the motor 125 drives the driving sprocket 122 and the driven sprocket 123 to rotate synchronously, the chain 124 moves back and forth along the transverse direction in a circulating manner, and then the plurality of blades 11 move along with the movement of the chain 124 to cut off the hot sheet along the transverse direction, thereby completing the cutting operation of the hot sheet.

Of course, in other embodiments, the driving structure for the blade to move in the transverse direction is not limited to the transmission structure of the sprocket and the chain, but a rodless cylinder may be used to drive the blade to move back and forth in the transverse direction, or a motor, a belt and a pulley structure may be used to drive the blade to move back and forth in the transverse direction, or a motor and a lead screw slider driving structure may be used to drive the blade to move back and forth in the transverse direction. In addition, the lifting mechanism is not limited to a pair of lifting frame structures arranged on the left side and the right side of the forming die, and can also be an integral lifting frame which is fixed on the forming die and extends along the transverse direction, and a driving structure for lifting the tool rest along the vertical direction can be provided, so that the tool rest is driven to move up and down firstly, a blade is used for inserting hot sheets, and then the cutting driving assembly is used for driving the blade to move along the transverse direction so as to cut off the sheets. The number of blades is not limited to a plurality, and only one blade structure may be provided, and the plurality of blades are provided for the purpose of improving cutting efficiency and are suitable for cutting a wide-sized thermal sheet.
