[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] like Figures 1 to 9 The hot pressing mechanism of the bending machine shown in the figure comprises: a frame 1, a heating mechanism 2 and a bending mechanism 3 fixedly connected to the frame 1. Figure 1 As shown, the heating mechanism 2 and the bending mechanism 3 are arranged in parallel, and a panel can pass between the two. The panel is first heated by the heating mechanism 2, and then bent by the bending mechanism 3.

[0033] Continue to refer Figure 1 , Figure 3 and Figure 4 As shown, the heating mechanism 2 includes a first heating module 21 and a second heating module 22 fixed on the frame 1. The first heating module 21 and the second heating module 22 are arranged opposite to each other and can be relatively close to or far away from each other. Since the enclosure has a certain thickness, in order to make the bending part of the enclosure evenly heated during the heating process, the enclosure is heated by two sets of heating modules arranged opposite to each other up and down, so as to achieve the effect of even heating of the enclosure.

[0034] The bending mechanism 3 includes a bottom plate 31 fixedly mounted on the frame 1, and a bending module 32 fixedly mounted on the frame 1 and capable of approaching or moving away from the bottom plate 31. Figure 1 , Figure 5 As shown, the heated enclosure needs to be pressed by placing the enclosure between the bending module 32 and the bottom plate 31 and using the punching force generated by the downward pressing of the bending module 32 to press the enclosure.

[0035] The heating mechanism 2 also has a heating fixed module 23, and the bending mechanism 3 also has a bending fixed module 33. Figure 1 , Figure 4 , Figure 5 As shown, in order to prevent the enclosure from being offset in position during the operation of the heating mechanism 2 and the bending mechanism 3, a heating fixed module 23 and a bending fixed module 33 are provided to fix the enclosure, thereby achieving precise positioning of the enclosure and improving the production accuracy of the enclosure bending to improve production efficiency.

[0036] like Figure 1 As shown, the utility model first fixes the enclosure by the heating fixed module 23 on the frame 1, and the fixed enclosure is heated on both sides of the enclosure by the first heating module 21 and the second heating module 22, and the heated enclosure is moved to the bottom of the bending mechanism 3, and the heated enclosure is fixed by the bending fixed module 33, and the punching force of the bending module 32 close to the bottom plate 31 is used to make the bending module 32 press the heated enclosure, so as to realize hot pressing of the enclosure, and the accuracy of hot pressing is improved by each fixed module, thereby improving the qualified rate of the product.

[0037] like Figure 3 , Figure 4As shown, in some embodiments of the utility model, the first heating module 21 includes a heating component 21a, a connecting rod 21b fixedly connected to the heating component 21a, and a plurality of driving components 21c fixedly connected to the connecting rod 21b at one end and fixedly connected to the frame 1 at the other end, wherein the second heating module 22 has the same structure as the first heating module 21. The enclosure is heated by the first heating module 21 and the second heating module 22 arranged relatively to each other, and the driving component 21c fixedly connected to the frame 1 is used to drive the fixedly connected connecting rod 21b and the heating component 21a, and the driving component 21c applies pressure to the connecting rod 21b so that the two connecting rods 21b move smoothly and parallelly toward each other to ensure the stability of the heating component 21a during the heating process, and to ensure that the height of the heating component 21a from the enclosure is the same when the enclosure is heated. It should be pointed out here that the driving component 21c has many forms, which can be a DC servo motor, an AC servo motor, or a stepper motor. The plurality of driving components 21 c are driven synchronously, so that the connecting rod 21 b moves in a direction perpendicular to the bottom plate 31 .

[0038] Through the above arrangement, when the heating component 21a heats the enclosure, in order to make the heating component 21a heat only the portion of the enclosure that needs to be bent, such as Figure 4 As shown, the heating assembly 21a includes a heat insulating plate 21a1 fixedly connected to the connecting rod 21b, and a heating lamp tube 21a2 arranged inside the heat insulating plate 21a1 and fixedly connected to the connecting rod 21b. The heat insulating plate 21a1 has an opening 21a3, the width of the opening 21a3 is the same as the width of the heating part of the enclosure, and the height of the heating lamp tube 21a2 is lower than the height of the opening 21a3. The heating lamp tube 21a2 is arranged inside the heat insulating tube. When the heating lamp tube 21a2 is powered on for heating, the heat is transferred to the enclosure through the opening 21a3 of the heat insulating tube. The heating width of the enclosure is controlled by adjusting the size of the opening 21a3 of the heat insulating plate 21a1. It should be pointed out here that the heat insulating plate 21a1 has many shapes, which can be a U-shaped plate, a V-shaped plate, or other shapes with an opening 21a3.

[0039] When the first heating module 21 and the second heating module 22 heat the enclosure, in order to keep the position of the enclosure unchanged, in some embodiments of the present invention, such as Figure 4As shown, the heating fixing module 23 is divided into a first heating fixing component 23a and a second heating fixing component 23b. The first heating fixing component 23a and the second heating fixing component 23b have the same structure and are arranged opposite to each other. The first heating fixing component 23a includes a fixing rod 23a1 which is parallel to and fixedly connected to the connecting rod 21b. The opposite surfaces of the two fixing rods 23a1 are fixing surfaces 23a2. The height of the fixing surface 23a2 is slightly higher than the height of the opening 21a3. The enclosure is fixed by the first heating fixing component 23a and the second heating fixing component 23b which are arranged opposite to each other, so that the position of the enclosure remains unchanged during the heating process. The enclosure is clamped by the fixing surface 23a2 on the fixing rod 23a1. The height of the fixing surface 23a2 is higher than the height of the opening 21a3. When the enclosure is clamped between the two fixing surfaces 23a2, the openings 21a3 of the two heat insulation boards 21a1 are used to accommodate the enclosure and will not contact each other, so as to prevent the heat insulation boards 21a1 from contacting the enclosure.

[0040] Through the above arrangement, in order to minimize the wear when the first heating and fixing assembly 23a and the second heating and fixing assembly 23b fix the enclosure, as shown in FIG. Figure 4 As shown, the fixing surface 23a2 is a rubber strip 23a3. The rubber strip 23a3 can reduce the damage to the enclosure plate caused by vibration and reduce the impact when the driving mechanism clamps the enclosure plate.

[0041] like Figure 5 , Figure 6 As shown, the bending module 32 includes a bending beam 32a arranged parallel to the bottom plate 31, a replaceable bending knife 32b fixed on the bending beam 32a and facing the bottom plate 31, and a plurality of driving members 32c connected to the frame 1 at one end and fixedly connected to the bending beam 32a at the other end. The heated enclosure is transported to the bottom of the bending module 32, and the driving member 32c drives the bending beam 32a close to the bottom plate 31. The bending knife 32b on the bending beam 32a presses the heated part of the enclosure to achieve the bending of the enclosure. It should be pointed out here that the shape of the bending knife 32b is changed according to the actual requirements for the bending part of the enclosure.

[0042] Through the above arrangement, the driving member 32c drives the bending beam 32a, and the multiple groups of driving members 32c are all servo cylinders 32c1, and the connection points between the multiple groups of servo cylinders 32c1 and the bending beam 32a are all rotational connections. The servo motor can make the movement of the bending beam 32a more synchronous, avoiding the bending beam 32a and the bottom plate 31 from being non-parallel, and the thickness of the bending part of the enclosure plate is different during pressing; the rotational connection method prevents the driving member 32c and the bending beam 32a from generating a force when the bending beam 32a is not parallel to the bottom plate 31, thereby damaging the driving member 32c and the bending beam 32a.

[0043] Similarly, if Figure 6 , Figure 8 , Fig. 9As shown, the bending and fixing module 33 is divided into a first bending and fixing component 33a and a second bending and fixing component 33b which are arranged in parallel on both sides of the bending beam 32a. The first bending and fixing component 33a and the second bending and fixing component 33b have the same structure. The first bending and fixing component 33a includes a fixed beam 33a1 connected to the bending beam 32a, and an anti-slip strip 33a2 arranged on the fixed beam 33a1 toward the bottom plate 31. The height of the anti-slip strip 33a2 toward the bottom plate 31 is slightly lower than the height of the bending knife 32b toward the bottom plate 31. The first bending and fixing assembly 33a and the second bending and fixing assembly 33b arranged on both sides of the bending knife 32b fix the heated enclosure, and the fixed beam 33a1 is movably connected with the bending beam 32a. When the bending beam 32a drives the two fixed beams 33a1 to move toward the bottom plate 31, the anti-slip strip 33a2 first contacts the enclosure, and the anti-slip strip 33a2 and the bottom plate 31 fix the enclosure. The bending knife 32b continues to press down to press the heated part of the enclosure. After the pressing is completed, all of them are retracted and moved to the next workstation.

[0044] In some embodiments of the present invention, the fixed beam 33a1 is movably connected to the bending beam 32a, so that when the enclosure is fixed, the fixed beam 33a1 is parallel to the extension direction of the bottom plate 31, such as Figure 7 As shown, there are multiple sets of elastic connectors 34 between the fixed beam 33a1 and the bending beam 32a, and the elastic connector 34 includes a connecting plate 34a fixedly connected to the bending beam 32a and provided with a through hole 34a1, a guide rod 34b fixedly connected to the fixed beam 33a1 at one end and passing through the through hole 34a1 at the other end, a spring 34c sleeved on the guide rod 34b, one end of which abuts against the fixed beam 33a1 and the other end passes through the through hole 34a1, and a stopper 34d fixed outside the spring 34c away from one end of the fixed beam 33a1 and fixedly connected to the connecting plate 34a. Multiple sets of elastic connectors 34 are evenly distributed on the fixed beam 33a1, and when the fixed beam 33a1 contacts the enclosure, the spring 34c is compressed, one end of the spring 34c abuts against the fixed beam 33a1, and the other end abuts against the stopper 34d, and the compressed spring 34c applies pressure to the fixed beam 33a1 to fix the enclosure.

[0045] In some embodiments of the present invention, Figure 1 , Figure 2As shown, the bending module 32 also has a guide assembly 35, which is arranged at both ends of the extension direction of the bending beam 32a. The bending module 32 includes a guide groove 35a fixed on the frame 1, and a guide block 35b fixedly connected to the fixed beam 33a1. The guide block 35b extends into the guide groove 35a and can slide relatively in the direction close to or away from the bottom plate 31. The bending beam 32a is connected to the driving member 32c. When the driving member 32c drives the bending beam 32a, the bending beam 32a is guided by the guide assembly 35 to make the movement trajectory of the bending knife 32b perpendicular to the bottom plate 31. The guide block 35b slides in the guide groove 35a to improve the bending accuracy.

The above embodiments and the description are only for explaining the principle of the present invention.
