Description

Technical Field

[0001] The utility model relates to the technical field of punching of pine needle boards, in particular to a punching and forming device for pine needle boards. Background Art

[0002] When processing pine needle lumber, punching and shearing are performed according to customer requirements. Existing punching and shearing machines are essentially processing tables with a punching cylinder mounted on one side. This cylinder drives a punching head to punch the lumber. During punching, workers manually move or secure the lumber. The punching head rises, carrying the lumber with it. A retaining frame on the outside of the punching head pushes the lumber down. This significant displacement of the lumber after movement and punching requires significant time for workers to adjust the lumber's punching position. Utility Model Content

[0003] The purpose of the present invention is to provide a pine needle board punching and forming device to solve the problem in the above background technology that the displacement amplitude of the board after moving and punching is large, which causes workers to spend a lot of time to adjust the board punching position.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A pine needle board punching and forming device comprises a punching cylinder, an inner rod end of the punching cylinder is fixedly installed with a punching head, a wing plate is provided at the port position of the punching cylinder, a threaded through hole is provided on the wing plate, a screw is installed at the position of the threaded through hole, a hexagonal column handle is fixedly installed on the upper end of the screw, the lower end of the screw is movably connected to a sleeve, a hidden groove connected to the inner cavity of the sleeve is provided in the screw, a spring is installed in the hidden groove, the upper end of the spring is fixedly connected to the top of the hidden groove, a clamping frame is provided below the sleeve, a column is provided on the upper side of the clamping frame, the column is inserted into the inner cavity of the sleeve, the spring is pressed on the top of the column, and a roller is movably installed on the inner side of the clamping frame through an axis.

[0006] As a further description of the above technical solution:

[0007] There is a distance between the punching head and the roller.

[0008] As a further description of the above technical solution:

[0009] The extended length of the spring is greater than the total height of the hidden groove and the inner cavity of the sleeve.

[0010] As a further description of the above technical solution:

[0011] The inner cavity of the sleeve is rectangular.

[0012] As a further description of the above technical solution:

[0013] The upright column is a rectangular column that matches the shape of the sleeve.

[0014] As a further description of the above technical solution:

[0015] The height of the column is greater than the height of the inner cavity of the sleeve.

[0016] Compared with the prior art, the present invention provides a pine needle board punching and forming device, which has the following beneficial effects:

[0017] 1. In this utility model, the limit frame on the outside of the punching head of the original punching cylinder is removed and replaced with a roller. The roller can be adjusted up and down according to the thickness of the plate. The roller presses on the plate and can be slightly moved up and down. The worker can move the plate in the rolling direction of the roller. After the punching head goes up, the plate is separated from the punching head, and the displacement of the plate is reduced, which shortens the time for workers to adjust the plate.

[0018] 2. In the present invention, the column can move up and down in the sleeve, but will not rotate. The position of the roller is fixed, and the spring presses down the column, exerting pressure on the roller. The roller will generate a force to press down and fix the plate, so that the plate will not be greatly tilted on the other side due to the force of pushing on one side.

[0023] 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.

[0024] Example:

[0025] See also Figure 1-Figure 2The utility model provides a pine needle board punching and forming device, including a punching cylinder 1, a punching head is fixedly installed at the inner rod end of the punching cylinder 1, a wing plate 2 is provided at the port position of the punching cylinder 1, a threaded through hole is provided on the wing plate 2, a screw rod 3 is installed at the position of the threaded through hole, the upper end of the screw rod 3 is fixedly installed with a hexagonal column handle 4, the lower end of the screw rod 3 is movably connected to the sleeve 5, a hidden groove communicating with the inner cavity of the sleeve 5 is provided in the screw rod 3, a spring 6 is installed in the hidden groove, the upper end of the spring 6 is fixedly connected to the top of the hidden groove, a clamping frame 7 is provided below the sleeve 5, and a column 8 is provided on the upper side of the clamping frame 7. The column 8 is inserted into the inner cavity of the sleeve 5, the spring 6 is pressed on the top of the column 8, and a roller 9 is movably installed on the inner side of the clamping frame 7 through the axis.

[0026] Specifically, a distance is left between the punching head and the roller 9 to avoid being stuck to each other.

[0027] Specifically, the extended length of the spring 6 is greater than the total height of the hidden groove and the inner cavity height of the sleeve 5, so that the column 8 can be adjusted in position and pushed out.

[0028] Specifically, the inner cavity of the sleeve 5 is rectangular, and the column 8 is a rectangular column that matches the shape of the sleeve 5 to limit the rotational displacement of the roller 9.

[0029] Specifically, the height of the column 8 is greater than the inner cavity height of the sleeve 5, which is convenient for adjustment.

[0030] Working principle:

[0031] When in use, according to the thickness of the plate, the hexagonal column handle 4 can be operated by hand or with a wrench to rotate the adjusting screw 3 until the roller 9 can contact the plate. Since the spring 6 has the telescopic self-adjusting property, the column 8 can be adjusted up and down along the sleeve 5, but the adjustment range is also limited by the height of the inner cavity of the sleeve 5. When the worker moves the plate, the roller 9 presses the plate, but not tightly, and it can be moved smoothly to the bottom of the punching head. Then the punching head rises after cutting, and moves up with the plate. When moving up, it is blocked by the roller 9, and the plate moves up slightly, and the amplitude is very small and it will break away from the punching head.

[0032] 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.
