Description

Technical Field

[0001] The utility model relates to the field of license plate frame bending devices, in particular to a front license plate frame bending device. Background Art

[0002] The front license plate frame is a component used to mount the license plate on the front end of the vehicle through the mounting holes and bolts. Since the front end of the vehicle is curved, the front license plate frame needs to be bent using a bending device after it is formed.

[0003] A Chinese patent with announcement number CN111069374A discloses a bending device and method for a front license plate bracket of a car, including a base plate, columns arranged in parallel on the upper surface of the base plate, and a fixed plate provided at the upper end of the column. A driving cylinder is provided on the fixed plate, and the piston rod of the driving cylinder is connected to a bending head. A supporting mechanism is also provided on the upper surface of the base plate. The supporting mechanism includes a left supporting platform, a right supporting platform, a driving component that drives the right supporting platform toward the left supporting platform, and a guiding component that guides the front license plate bracket when it bends. A limiting mechanism is respectively provided on the left supporting platform and the right supporting platform to clamp and limit the front license plate bracket placed between the two.

[0004] In the above structure, the front license plate bracket needs to be placed on the upper surface of the left support platform and the right support platform before the bending process, and then the bending head is driven down by the driving cylinder to bend the front license plate bracket. However, since the driving cylinder is arranged above the left support platform and the right support platform, when the worker places the front license plate bracket on the two support platforms, the worker's hand is likely to come into contact with the bending head arranged below the driving cylinder and be injured. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that since the driving cylinder is arranged above the two supporting platforms, the hands of workers are easily injured by contact with the bending head when placing the front license plate bracket. The utility model provides a front license plate frame bending device which can improve the safety of workers in loading materials.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] A front license plate frame bending device includes a workbench, a lower mold arranged on the workbench for placing the front license plate frame, an upper mold arranged above the lower mold, and a lifting component that drives the upper mold to descend vertically and close the mold with the lower mold. After the upper and lower molds are closed, a bending cavity is formed between the two to give the front license plate frame a required curvature. The lower mold is horizontally guided and slid on the workbench and can be moved to just below the upper mold or moved to be completely offset from the upper mold. The movement of the lower mold is controlled by a driving component.

[0008] By adopting the above scheme, the driving component can be set up to drive the lower mold to move until the upper mold descends or moves to a position completely misaligned with the upper mold. When the driving component drives the lower mold to move to a position completely misaligned with the upper mold, the worker can place the front license plate frame on the lower mold. Because the lower mold and the upper mold are completely misaligned when the worker places the front license plate frame on the lower mold, the probability of accidental injury to the worker when placing the front license plate frame is reduced; when the driving component drives the lower mold to move to the bottom of the upper mold, the driving lifting component can drive the upper mold to descend and close the mold with the lower mold. Because a bending cavity is provided between the two to make the front license plate frame form the required curvature, the front license plate frame placed on the lower mold can be bent when the two are closed.

[0009] Preferably, the driving component includes a rodless cylinder arranged on the upper surface of the workbench, and the lower mold is fixedly connected to a slider of the rodless cylinder.

[0010] By adopting the above solution, the rodless cylinder drives the slider and the lower die fixed thereto to slide, so that the lower die slides below the upper die or slides to a position completely misaligned with the upper die.

[0011] Preferably, guide rails extending along the driving direction of the rodless cylinder are fixed in parallel on both sides of the rodless cylinder on the workbench, and a guide block is fixed on the bottom of the lower mold to be embedded and slidable with the guide rails.

[0012] With the above solution, the guide block arranged at the bottom of the lower die can slide on the guide rail when the rodless cylinder drives the lower die to move, thereby guiding the movement of the lower die.

[0013] Preferably, a plurality of mounting protrusions are provided on the back of the license plate frame with the mounting hole as the center, and a positioning structure for placing the mounting protrusions and using the mounting protrusions to quickly position the front license plate frame is provided on the lower mold.

[0014] Preferably, the positioning structure includes a positioning groove provided on the lower mold for the central mounting protrusion of the front license plate frame to be positioned and inserted, and a plurality of avoidance grooves for the remaining mounting protrusions of the front license plate frame to be inserted when deformed by bending.

[0015] By adopting the above solution, the mounting protrusion on the front license plate frame can be partially inserted into the positioning groove provided in the middle of the lower mold, thereby positioning the front license plate frame placed on the lower mold, making it convenient to bend the front license plate frame when the upper mold and the lower mold are subsequently closed.

[0016] Preferably, the upper surface of the lower mold is bent and convex toward the middle to form a mold closing convex surface, and the lower surface of the upper mold is bent and concave toward the middle to form a mold closing concave surface. The mold closing convex surface and the mold closing concave surface form the curved cavity when the mold is closed.

[0017] With the above solution, when the upper mold and the lower mold are closed, the mold closing convex surface on the lower mold cooperates with the mold closing concave surface on the upper mold, thereby bending the front license plate frame placed on the lower mold.

[0018] Preferably, the lifting component includes a mounting plate horizontally arranged above the upper mold, and a downwardly directed cylinder arranged at the protruding end of the mounting plate, the protruding end of the cylinder passes through the mounting plate and is fixed to the surface of the upper mold, and vertical guide components are respectively arranged on both sides of the cylinder to guide the lifting and lowering of the upper mold.

[0019] By adopting the above scheme, the cylinder can be set up to drive the upper mold to descend and close the mold with the lower mold when the lower mold moves to the bottom of the upper mold, thereby bending the front license plate frame placed on the lower mold, and the vertical guide components arranged on both sides of the cylinder can guide the lifting and lowering of the upper mold, so that the upper mold can be lifted and lowered in the vertical direction.

[0020] Preferably, the vertical guide component includes a guide column vertically arranged on both sides of the cylinder, one end of which is fixed to the upper mold surface and the other end extends outside the mounting plate, and a guide sleeve arranged on the mounting plate to guide the lifting and lowering of the guide column.

[0021] By adopting the above solution, the guide column can slide in the guide sleeve when the upper mold is raised or lowered, thereby guiding the raising and lowering of the upper mold and realizing the vertical raising and lowering of the upper mold.

[0022] Preferably, a plurality of insertion holes are arranged at intervals on the side wall of the lower mold and pass through the lower mold horizontally, and cooling water pipes are arranged in the insertion holes to cool the front license plate frame placed on the lower mold.

[0023] By adopting the above solution, the front license plate frame produced by molding and placed on the lower mold can be cooled by the cooling water pipe arranged in the lower mold socket.

[0024] Preferably, drag chains are provided on both sides of the lower mold to facilitate wiring for the operator.

[0025] By adopting the above solution, the interior of the drag chain can be used to install cables, thereby making the wiring more neat. At the same time, the cables installed therein can be protected and their service life can be increased.

[0026] Due to the adoption of the above technical scheme, the utility model has significant technical effects: the driving component is set to drive the lower mold to move until the upper mold descends or moves to a position completely misaligned with the upper mold. When the driving component drives the lower mold to move to a position where it is completely misaligned with the upper mold, the worker can place the front license plate frame on the lower mold. Because the lower mold and the upper mold are completely misaligned when the worker places the front license plate frame on the lower mold, the probability of accidental injury to the worker when placing the front license plate frame is reduced; when the driving component drives the lower mold to move to the bottom of the upper mold, the driving lifting component can drive the upper mold to descend and close the mold with the lower mold. Because a bending cavity is provided between the two to make the front license plate frame form the required curvature, the front license plate frame placed on the lower mold can be bent when the two are closed.
