[0002] As a common structure for connecting two plates, hinges are widely used in automotive interiors, spare tire covers, coat racks, trunk carpet front trims and other product structures. There are various ways to process hinges. At present, the most widely used methods for forming hinges for automobile trunk front trims are hot pressing creases and die cutting. The hot pressing crease process requires the heated blade to heat and pressurize the surface of the product, which has high requirements for the temperature consistency and heat resistance of the blade material. The formed hinge has poor consistency, long time and low efficiency. The die cutting process uses a die die and a press to punch the product to form a hinge. The parallelism of the die die and the press is very high. The depth uniformity of the die-cutting hinge is not high, and the appearance consistency of the formed hinge is poor after folding. The die die has short life and other disadvantages. In view of this, we propose a device for processing and forming hinges for automotive interiors. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] Reference Figure 1-Figure 3 A sliding cutting and forming device for hinges of an automobile trunk interior panel comprises a work surface 1, and a switch knob 3 arranged on the work surface 1 for starting a process, a pressing component 4 for fixing a product is arranged on the work surface 1, and a processing component 5 for manufacturing a hinge is arranged on the work surface 1. When the device is used, the product is first placed on the work surface 1, and then fixed by the pressing component 4, so as to ensure that the product does not shift during the sliding cutting process, and finally the operator gives a signal by starting the switch knob 3, and after the processing component 5 is exposed to the signal, it starts to operate automatically, thereby completing the production of the hinge.

[0022] The processing assembly 5 comprises a processing bracket 51 fixedly mounted on the worktable 1, a fixed screw 52 is rotatably mounted on the processing bracket 51, a servo motor 54 whose output end is coaxially fixed with the fixed screw 52 is fixedly mounted on the processing bracket 51, a displacement slider 53 is provided on the external thread sleeve of the fixed screw 52, ​​and a limiting protrusion is provided at the lower part of the displacement slider 53, a limiting slide groove for sliding the limiting protrusion is provided on the processing bracket 51, a sliding cutter 56 is provided at the lower part of the displacement slider 53, and an adjustment assembly 55 for hinge depth is provided on the displacement slider 53, and pulleys 57 for pressing and fixing the product are provided on both sides of the sliding cutter 56. During the processing, the adjustment assembly 55 is firstly adjusted to adjust the depth of the hinge. The distance between the sliding cutter 56 and the work surface 1 is adjusted so that the hinge can be adjusted according to the product requirements, and then the servo motor 54 is started to control the rotation of the fixed screw 52, ​​and the threaded connection between the displacement slider 53 and the fixed screw 52 is utilized to drive the sliding cutter 56 to move under the fixed screw 52, ​​so as to cut a hinge with uniform depth in the product. In addition, during the process of sliding cutting the hinge, the pulley 57 rolls with the sliding cutter 56 and presses the product, ensuring that the sliding cutter 56 presses the product tightly against the work surface 1 during the process of sliding cutting the hinge, preventing the product from moving or deforming during the cutting process, thereby ensuring the cutting accuracy and quality, and making the hinge line straight and not offset.

[0023] The adjustment component 55 includes a slide rail 551 arranged on the displacement slider 53, an adjustment slider 552 is slidably installed on the slide rail 551, and the adjustment slider 552 is fixedly connected to the sliding cutter 56. The displacement slider 53 is provided with an adjustment handle 553 for controlling the position of the adjustment slider 552 on the slide rail 551. During sliding cutting, the position of the adjustment slider 552 on the slide rail 551 can be controlled by the adjustment handle 553, thereby achieving the function of adjusting the hinge depth, expanding the application scope of the equipment, and facilitating the promotion of the equipment.

[0024] The sliding cutter 56 is detachably connected to the displacement slider 53 by installing screws. The design of the detachable connection between the sliding cutter 56 and the displacement slider 53 allows sliding cutters 56 of different specifications to be replaced accordingly, which simplifies the installation and disassembly process of the sliding cutter 56 and reduces labor intensity.

[0025] Embodiment 2

[0026] Reference Figure 1-Figure 3 This embodiment is basically the same as the first embodiment, and is more optimized in that the pressing assembly 4 includes a fixing frame 41 fixedly mounted on the work surface 1, a cylinder 42 is provided on the fixing frame 41, a pressing block 43 for pressing the product is provided at the output end of the cylinder 42, and the pressing block 43 is slidably connected to the fixing frame 41. After the product is placed, the pressing block 43 can be driven by starting the cylinder 42 to press the product, thereby reducing the probability of movement during the sliding cutting process, thereby ensuring the normal sliding cutting work, and the hinge produced has the advantage of high consistency.

[0027] The air pressure of cylinder 42 is 0.6Mpa-0.8Mpa. The significance of the air pressure of cylinder 42 being 0.6Mpa-0.8Mpa is that within this pressure range, the gas pressure in cylinder 42 is sufficient to drive the piston to move, so that the pressure block 43 can press the product without causing compression damage to the product, thereby protecting the product to a certain extent.

[0028] The work surface 1 is provided with a positioning pin 2 for positioning the product. The positioning pin 2 is mainly used to facilitate the positioning of the product, ensure the stability of its relative position with other components on the work surface 1, prevent loosening and displacement, and thus improve the manufacturing effect of the hinge.

[0029] Working principle:

[0030] When the device is used, the product is first placed on the work surface 1, and then fixed by the pressing component 4, that is, the pressure block 43 is driven by the start cylinder 42 to press the product, thereby reducing the probability of movement during the sliding cutting process, thereby ensuring the normal sliding cutting work, so that the hinge produced has the advantage of high consistency, and then the operator gives a signal by starting the switch knob 3. After the processing component 5 contacts the signal, the servo motor 54 is started to control the rotation of the fixed screw rod 52, and the threaded connection between the displacement slider 53 and the fixed screw rod 52 is used to drive the sliding cutter 56 to move in the fixed position. The fixed screw rod 52 moves downward, thereby cutting a hinge with uniform depth in the product. In addition, the pulley 57 rolls with the sliding cutter 56 and presses the product during the process of sliding cutting the hinge, ensuring that the sliding cutter 56 presses the product tightly against the work surface 1 during the process of sliding cutting the hinge, preventing the product from moving or deforming during the cutting process, thereby ensuring the cutting accuracy and quality, and making the hinge line straight and not offset. In addition, the distance between the sliding cutter 56 and the work surface 1 can be adjusted by the adjustment component 55 before production, so that the hinge can be adjusted according to product requirements, thereby completing the production of the hinge.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
