Description

Technical Field

[0001] The utility model relates to the technical field of punching dies, in particular to a punching die for a hemp fiber seat backboard. Background Art

[0002] Hemp fiber seat back punching dies are used to produce hemp fiber seat backs, commonly found in furniture such as car seats and office chairs. Hemp fiber seat backs offer excellent breathability and comfort. Punching dies are tools used to perform punching, shearing, bending, and stretching operations on metal or other materials. These dies can be used to create hemp fiber seat backs in various shapes and sizes to meet design requirements. These dies typically consist of a base plate, upper and lower dies, and guide posts. Mechanical or hydraulic equipment moves the upper and lower dies back and forth to produce the hemp fiber seat backs.

[0003] When using some existing hemp fiber seat back panel punching molds, they usually punch around the four sides of the back panel, so that some docking holes on the surface of the back panel need to be punched again later. Because of the need for repeated punching, the back panel takes a lot of time to process. Therefore, this problem needs to be solved. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a punching die for a hemp fiber seat back panel.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A hemp fiber seat backboard punching mold includes an operating table, a top mold is provided on the top of the operating table, a lifting mechanism for raising and lowering the top mold is provided on the top of the top mold, a storage groove is provided at the bottom of the top mold, a tool is slidably connected to the inside of the storage groove, a plurality of limit rods are fixedly connected to the top of the tool, and a reset mechanism for resetting the tool is provided on the surface of the plurality of limit rods, a plurality of slide grooves are provided on the top of the top mold, a plurality of punching columns are slidably connected to the inside of the plurality of slide grooves, and an adjustment mechanism for adjusting the punching columns is provided on the top of the plurality of punching columns. By setting the punching columns, the backboard surface can be punched.

[0007] As a further solution of the present invention, the lifting mechanism includes a gantry, which is fixedly connected to the top of the operating table. Two hydraulic rods are fixedly connected to the top of the gantry, and the top mold is fixedly connected to the bottom of the two hydraulic rods. The top of the operating table close to the top mold is fixedly connected to the bottom mold. The top mold and the bottom mold are arranged to cooperate with each other. The top mold can be controlled to rise and fall through the setting of the hydraulic rod.

[0008] As a further solution of the present invention, the reset mechanism includes a limit plate, which is fixedly connected to the top of the limit rod. A spring is provided on the surface of the limit rod close to the limit plate. The bottom end of the spring is fixedly connected to the top of the top mold, and the top end of the spring is fixedly connected to the limit plate. The tool can be reset by setting the spring.

[0009] As a further solution of the present invention, the adjustment mechanism includes a constraint disk, which is rotatably connected to the top of the punching column, and the top of the top mold close to the constraint disk is fixedly connected to a support column, and the top of the support column is hinged with a support arm, and both ends of the support arm are slidably connected with extension arms, the constraint disk is hinged to one end of one of the extension arms, and the other end of the extension arm is hinged to a connecting rod away from the constraint disk. The connecting rod is fixedly connected to the top of the tool, and a rotating mechanism for rotating the punching column is provided on the surface of the punching column. The punching column can be adjusted by setting the support arm.

[0010] As a further solution of the present invention, the rotating mechanism includes a thread groove, which is opened on the surface of the punching column. A constraint column is slidably connected inside the thread groove, and the constraint column is fixedly connected to one side of the inner part of the slide groove. Through the setting of the constraint column, the punching column can be rotated.

[0011] The beneficial effects of the utility model are:

[0012] 1. By setting the punching column, the surface of the backboard can be punched. The punching column is installed on the other side of the support arm, so that as the tool continues to move upward, the punching column will contact the backboard and punch it, so as to avoid secondary punching of the backboard at a later time.

[0013] 2. The setting of the thread groove can make the punching effect of the punching column better. A thread groove is installed on the surface of the punching column, and a constraint column is installed inside the thread groove. Because the constraint column is installed on one side of the top mold, when the punching column moves downward, it can also rotate, so that the punching column can punch more smoothly.

Through the setting of the spring 303, the tool 3 can be reset.

[0024] Reference Figure 2-Figure 4 In a preferred embodiment, the adjustment mechanism includes a restraining disk 403, which is rotatably connected to the top of the punching column 404. The top of the top mold 202 close to the restraining disk 403 is fixedly connected to a support column 402, and the top of the support column 402 is hinged with a support arm 401. Both ends of the support arm 401 are slidably connected to an extension arm 407.

[0025] Reference Figure 2 and Figure 4 In a preferred embodiment, the rotating mechanism includes a thread groove 405, which is opened on the surface of the punching column 404. A constraint column 406 is slidably connected inside the thread groove 405. The constraint column 406 is fixedly connected to one side of the inner part of the slide groove 204. Through the setting of the constraint column 406, the punching column 404 can be rotated.

[0026] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when in use, the back plate is placed on the top of the bottom die 101, and then the hydraulic rod 201 is started, and a top die 202 is installed at the bottom of the hydraulic rod 201, so that as the hydraulic rod 201 continues to move downward, the top die 202 can be matched with the bottom die 101, and a tool 3 is installed at the bottom of the top die 202, so that when the top die 202 contacts the bottom die 101, the tool 3 can punch the back plate, and a support arm 401 is installed on the top of the tool 3, because the tool 3 is connected to the top die 202 through the spring 303, so that when the tool 3 contacts the back plate, it will continue to move upward, because the support arm 401 is installed on the top of the top mold 202 through the support column 402, so that when one end of the support arm 401 moves up, the other end will move down accordingly. A punching column 404 is installed on the other side of the support arm 401, so that as the tool 3 continues to move up, the punching column 404 will contact the back plate and punch it to avoid secondary punching of the back plate later. A threaded groove 405 is installed on the surface of the punching column 404, and a constraint column 406 is installed inside the threaded groove 405. Because the constraint column 406 is installed on one side of the inside of the top mold 202, the punching column 404 can also rotate when it moves down, so that the punching column 404 can punch more smoothly.
