Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine for glasses processing. Background Technique

[0002] Glasses are simple optical devices made for correcting eyesight or protecting the eyes, consisting of lenses and frames. There are four types of glasses for correcting eyesight: myopia glasses, hyperopia glasses, presbyopia glasses, and astigmatism glasses. Other types of glasses include goggles, sunglasses, swimming goggles, etc., providing various protections for the eyes. Glasses are both tools for protecting the eyes and a kind of beauty decoration. When processing spectacle frames, in the current spectacle manufacturing and processing process, the whole spectacle frame needs to be bent to make it reach a suitable curvature for more comfortable wearing. When processing the spectacle frame, it is necessary to press the spectacle frame through a glasses bending machine.

[0003] The patent with the publication number CN219541582U proposes a glasses bending machine, which relates to the field of glasses processing equipment. The glasses bending machine includes a base and two pressing seats. A support frame is fixedly connected to the top of the base, and a pressing device for pressing the spectacle frame is installed on the top wall of the support frame. The bottoms of the two pressing seats are both fixedly connected to the top of the base. A positioning pad for positioning the spectacle frame is installed on the top of the pressing seat. An air inflation device for jacking up the spectacle frame is arranged on the pressing seat, and the bottom of the air inflation device is installed on the inner wall of the base. The glasses bending machine provided by the utility model, through the arranged air inflation device, ventilates into multiple air ducts through the air inlet assembly, enters the inner cavity of the placement groove through the ventilation holes, and under the action of air pressure, the fixing ring and the top plate move upward, and the elastic member is stretched. The upward moving top plate pushes the spectacle frame. Since there are multiple top plates, multiple points of the spectacle frame can be pushed, so that the spectacle frame is not easily deformed when taken.

[0004] When the above structure is in use, the size of the pressing die is fixed, which is not convenient to replace temporarily, not convenient to bend spectacle frames of different sizes, and has high limitations in use. Content of the Utility Model

Specific implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , a bending machine for glasses processing according to the present utility model includes a processing table 1, a fixed seat 3 and a thruster 14 are fixedly arranged at the upper end of the processing table 1, a limit seat 12 is arranged at the output end of the thruster 14, a first bending seat 13 is arranged on one side of the limit seat 12, a jack is arranged on the limit seat 12, a plug piece cooperating with the jack is arranged on the first bending seat 13, a second bending seat 4 is arranged on one side of the fixed seat 3 close to the first bending seat 13, a positioning groove 8 is arranged inside the fixed seat 3, a clamping groove is arranged on the inner wall of the positioning groove 8, a positioning block 5 cooperating with the positioning groove 8 is arranged on the second bending seat 4, cavities are arranged on both sides of the positioning block 5, a first spring 7 is arranged inside the cavities, a clamping block 6 cooperating with the clamping groove is arranged at one end of the first spring 7, and a push rod 9 capable of penetrating the positioning groove 8 is arranged outside the fixed seat 3;

[0024] When the present structure is in use, the cooperation between the first bending seat 13 and the limiting seat 12 is similar to the cooperation between a plug and a socket, and it is not necessary to make too much description here. The cooperation between the card block 6 and the card slot can fix the second bending seat 4 on the fixing seat 3. Starting the pusher 14 can make the limiting seat 12 drive the first bending seat 13 to move. Through the cooperation between the first bending seat 13 and the second bending seat 4, the frame can be bent. The limiting seat 12 has an independent power supply, and the first bending seat 13 has a heating module. When the first bending seat 13 is connected to the limiting seat 12, the heating module can heat the first bending seat 13, thereby softening the frame.

[0025] By pushing the push rod 9, when the thrust is greater than the elastic force of the first spring 7, the card block 6 can be disengaged from the card slot, so that the positioning block 5 can be pulled out of the positioning slot 8, and the second bending seat 4 can be easily replaced (different second bending seats 4 have mold slots of different sizes). By pulling the first bending seat 13, the insert piece can be disengaged from the plug hole, and the first bending seat 13 can be easily replaced (different first bending seats 13 have modules of different sizes), thereby facilitating the bending of frames of different sizes, and having low limitations during use.

[0026] In this structure, two guide blocks are symmetrically arranged at the outer end of the push rod 9, two guide rods 10 penetrating the guide blocks are symmetrically arranged on the outer wall of the fixed seat 3, and a second spring 11 penetrated by the guide rod 10 is arranged between the fixed seat 3 and the guide block. When the push rod 9 is pushed, the second spring 11 will be compressed, and the push rod 9 can be easily reset through the rebound effect of the second spring 11.

[0027] Furthermore, the card block 6 and the card slot may both be trapezoidal structures.

[0028] Furthermore, two clamping grooves are symmetrically arranged on the outer wall of the positioning groove 8 , and two clamping blocks 6 are symmetrically arranged on both sides of the positioning block 5 , so that the positioning block 5 and the positioning groove 8 can be more firmly matched.

[0029] Furthermore, an empty slot 15 is provided on the fixed seat 3, an inclined rod 16 is obliquely arranged inside the empty slot 15, a positioning shaft is provided in the middle part of the inclined rod 16, a positioning seat 2 is fixedly arranged on the outer side of the limiting seat 12, and both ends of the positioning shaft are rotatably connected to the positioning seat 2. Two empty slots 15 are symmetrically arranged on the limiting seat 12. When the outer end of the inclined rod 16 is moved, the front end of the inclined rod 16 will move in the empty slot 15, thereby providing a thrust to the first bending seat 13, making it convenient to disassemble the first bending seat 13 on the limiting seat 12.
