Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and in particular to a picture frame bending device. Background Technology

[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or for decorative purposes. The frames consist of two parts: the frame and the temples. They can be made of metal or cellulose acetate. When making eyeglass frames from cellulose acetate, the material needs to be cut into the shape of the frame, and then the frame is bent to a certain extent to fit the contours of the face.

[0003] For example, Chinese utility model patent CN218838035U discloses a hydraulic mold for bending mirror frames. This design facilitates the replacement of hydraulic molds of different specifications, thereby increasing bending efficiency, and allows for clamping and fixing of the hydraulic mold to prevent displacement during pressing. However, this structure still has the following significant drawbacks:

[0004] 1. Before bending, the frame needs to be heated in a bending machine to soften it before bending. After forming, it needs to be removed manually. When removing it, the frame is still very hot, which can easily burn the workers' hands. Therefore, thick gloves need to be worn, which makes the workers have a poor working experience.

[0005] 2. After bending the frame, most frame bending devices will cause the frame to stick to the workbench. Operators need to manually separate the frame from the workbench with tools in order to remove and collect the frame. This operation is troublesome and time-consuming, which can easily lead to low production efficiency. Summary of the Invention

[0006] This utility model aims to solve one of the technical problems existing in the prior art.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The following description, in conjunction with the accompanying drawings, details a picture frame bending device provided in this application through specific embodiments and application scenarios.

[0028] Example 1:

[0029] like Figures 1 to 3 As shown, this application embodiment provides a mirror frame bending device, including a workbench 1, a pressing structure 2, a guide rod 3, a cylinder 4, and a placement platform 6; the workbench 1 has an installation cavity 11, a cooling pipe 12 is fixedly installed in the installation cavity 11, an installation block 13 is fixedly installed on the side wall of the workbench 1, a conveying pipe 14 is fixedly installed on the installation block 13, a connecting groove 15 is provided in the installation block 13, the two ends of the connecting groove 15 are respectively connected to the water inlet end of the cooling pipe 12 and the conveying pipe 14, and a scale inhibitor 16 is provided on the installation block 13, which can prevent the formation of scale on the water cooling pipe.

[0030] Furthermore, the scale inhibition device 16 includes a storage chamber 161, a metering block 162, a rotating shaft 163, and a push rod 164. The mounting block 13 is provided with a storage chamber 161, which is connected to the connecting groove 15 through a discharge channel 165. The rotating shaft 163 is fixedly installed in the connecting groove 15. A metering block 162 for blocking the discharge channel 165 is rotatably installed on the rotating shaft 163. A metering groove is fixedly installed at the top of the metering block 162, and a push rod 164 is fixedly installed at the bottom of the metering block 162.

[0031] Furthermore, a rubber block 167 is fixed on the quantitative block 162.

[0032] Furthermore, the cooling pipe 12 inside the mounting cavity 11 is wavy.

[0033] Furthermore, the inlet and outlet of the cooling pipe 12 are located on the same side of the workbench 1.

[0034] Furthermore, the cooling pipe 12 is made of brass.

[0035] In this embodiment of the application, due to the above-mentioned structure, a cylinder 4 is fixedly installed on the workbench 1. The output shaft of the cylinder 4 is fixedly connected to the pressing structure 2. A guide rod 3 is fixedly provided at the top of the pressing structure 2. The workbench 1 is provided with a placement platform 6 made of aluminum alloy and a guide sleeve that slides with the guide rod 3. By placing the mirror frame on the placement platform 6 and starting the cylinder 4, the cylinder 4 will push the pressing structure 2 to slide downward, causing the mirror frame to bend until the mirror frame is bent into shape. The external control system automatically introduces cooling water. The cooling water enters the cooling pipe 12 through the delivery pipe 14 and the connecting groove 15 in sequence. During the flow of the cooling water in the cooling pipe 12, the heat of the placement platform 6 and the mirror frame can be carried away, thereby achieving the purpose of cooling down.

[0036] The mounting block 13 is provided with a storage chamber 161, which stores scale inhibitor. Under the action of gravity, the scale inhibitor will fill the metering tank. When cooling water passes through the connecting groove 15, the cooling water will push the push rod 164, causing the push rod 164 and the metering block 162 to rotate around the rotating shaft 163. The rotation of the metering block 162 causes the metering tank, which was originally facing the storage chamber 161, to turn towards the end of the conveying pipe 14, thereby allowing the scale inhibitor in the metering tank to enter the cooling water. The scale inhibitor effectively prevents the formation of scale in the cooling pipe 12, ensuring the heat conduction effect and further ensuring the cooling efficiency. After the operation is completed, under the influence of gravity, the push rod 164 and the metering block 162 reset, and the metering tank turns back towards the storage chamber 161.

[0037] The mounting block 13 is equipped with an openable cover plate, which allows scale inhibitor to be added to the storage chamber 161 by opening the cover plate;

[0038] A rubber block 167 is fixed on the metering block 162, and the rubber block 167 serves a sealing function.

[0039] The cooling pipe 12 inside the mounting cavity 11 is wavy. When the cooling water enters the cooling pipe 12, the cooling pipe 12 can extend the cooling water delivery time, so that the cooling water can absorb heat more fully.

[0040] The inlet and outlet of the cooling pipe 12 are located on the same side of the workbench 1, which facilitates the centralized arrangement of pipe interfaces, reduces pipe cross-interference, and improves the installation efficiency and space utilization of the cooling system.

[0041] The cooling pipe 12 is made of brass, which has high thermal conductivity and can quickly transfer heat to the cooling water inside the cooling pipe 12.

[0042] Example 2:

[0043] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, a positioning block 51 is fixed on the placement platform 6, and an ejector block 52 that slides with the positioning block 51 is provided on the worktable 1. Through the driving device 53, the driving device 53 can drive the ejector block 52 to slide synchronously after the pressing structure 2 slides upward a certain distance.

[0044] Furthermore, the ejection device includes a connecting rod 531 and a bottom block 532. The ejection block 52 is provided with a connecting hole 533 that slides with the connecting rod 531. The connecting rod 531 is fixedly mounted on the pressing structure 2. The bottom end of the connecting rod 531 passes through the connecting hole 533 through the ejection block 52 and is fixedly mounted on the bottom block 532.

[0045] In this embodiment of the application, due to the above-described structure, a pair of positioning blocks 51 are fixed on the top of the placement platform 6 and match the slots on the frame for installing lenses. The ejector block 52 is provided with a sliding groove, which slides in cooperation with the positioning block 51. After the frame is bent and cooled, the cylinder 4 can drive the pressing structure 2 to slide upward along the guide rod 3 until the top of the bottom plate contacts the bottom of the ejector block 52. The pressing structure 2 then slides upward to drive the ejector block 52 to slide upward, thereby ejecting the frame. The frame can be removed from the placement platform 6 without the need for other tools, making it convenient for operators to collect. After removal, the cylinder 4 pushes the pressing structure 2 downward a certain distance to reset the ejector block 52.
