Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, in particular to metal cutting equipment for casement window processing. Background Art

[0002] Casement doors and windows refer to doors and windows that are fixed on the side of holes or openings with two or more parallel or vertical points as the axis, and can be opened manually, electrically, by chain, twist, rotation, or magnetically. They have certain ventilation, lighting and locking functions. They are divided into inward-opening, outward-opening, free, top-hung, bottom-hung, center-hung, transfer, folding, and lifting.

[0003] As is known, aluminum alloy has high hardness, is not easy to deform, can withstand large wind pressure, and the surface of aluminum alloy is oxidized or sprayed, which is anti-oxidation, acid and alkali resistant, not easy to rust, and has high corrosion resistance. In summary, the material of casement windows is generally made of aluminum alloy. In order to meet the production and processing needs of casement windows, cutting equipment is required to cut aluminum.

[0004] The cutting equipment in the prior art, such as the Chinese patent with the authorization announcement number CN116765504B and the name of a fixed profile aluminum cutting device, discloses an aluminum cutting device that can fix profiles, including a frame, a workbench, a guide frame, an electric screw, a sliding frame and an electric saw blade, the frame is rotatably connected to the workbench, a long strip opening is opened in the middle of the workbench, the rear side of the workbench is connected to the guide frame, the rear side of the guide frame is installed with an electric screw, the electric screw is threadedly connected to the sliding frame, the sliding frame and the guide frame are slidably matched, the front side of the sliding frame is installed with an electric saw blade, and also includes a conveying mechanism and a limiting mechanism, the left side of the frame is provided with a conveying mechanism for conveying aluminum, and the frame is provided with a limiting mechanism for fixing and limiting the aluminum.

[0005] Another example is the Chinese patent with the authorization announcement number CN216462240U, entitled "An environmentally friendly aluminum cutting device". The above patent discloses an environmentally friendly aluminum cutting device, including a chassis, a cutting mechanism and a dust suction mechanism. The cutting mechanism is fixedly installed on the top of the chassis, and the dust suction mechanism is fixedly installed on the top of the cutting mechanism. The cutting mechanism includes a sound absorbing shell, which is fixedly installed on the top of the chassis, and the inner wall of the sound absorbing shell is rotatably connected to a cutting disc. In the above patent, by setting up a dust suction mechanism, the dust extraction fan is used to draw the waste generated by the cutting disc when it is working into the dust collection box through the dust suction head and the guide hose to prevent the waste from splashing to various places in the workshop.

[0006] In the prior art such as the above-mentioned patents, the cutting needs of metal parts can be satisfied to a certain extent. As is well known, waste chips are generated during the cutting of metal parts, and a large amount of heat is generated due to the intense friction between the cutting tool and the metal part during the cutting process of the metal part. At this moment, contact between the high-temperature waste chips and the skin may cause burns, especially the flying fine particles. Therefore, in the prior art such as the above-mentioned patents, a protection component is generally used to protect the cutting station during the cutting process. However, in the prior art such as the above, the surface of the metal part cannot be protected. At this moment, there is a situation where the high-temperature waste chip particles fall on the upper surface of the metal part, which will damage the protective layer on the surface of the metal part, not only affecting the service life of the metal part but also affecting the appearance. At the same time, during the cutting of the metal part, a fastening mechanism is required to fix the metal part to improve the stability during the cutting of the metal part. In the prior art, a separate drive source is used to drive the fastening mechanism to fix the metal part. At this moment, multiple hardware components and complex software algorithms need to be integrated, resulting in a significant increase in the initial R & D and deployment costs and being inconvenient for later maintenance.

[0007] Therefore, it can be seen that how to protect the surface of the metal part while passively fixing the metal part during the stroke of the cutting mechanism moving to the cutting station is a technical problem that urgently needs to be solved. Summary of the Invention

[0008] The purpose of the present invention is to provide a metal cutting device for processing flat windows to solve the problems raised in the above background technology.

[0009] To achieve the above purpose, the present invention provides the following technical solution: A metal cutting device for processing flat windows, including a frame and a working frame installed on the frame. A carrier table is slidably connected to the working frame through a power cylinder. A cutting mechanism is installed on the carrier table. A metal part to be cut is installed on the working frame below the cutting mechanism. Protection mechanisms are provided on both sides of the cutting mechanism, and a protection space is formed between the two protection mechanisms; The protection mechanism includes a backing plate, connecting seats are installed on both sides of the backing plate, and a protection buffer is provided between the carrier table and the connecting seats, and each connecting seat is connected to the backing plate through an extrusion protection part.

[0010] Further, the extrusion protection part includes an extrusion plate, and the backing plate is slidably connected to the extrusion plate through a connecting unit; A trigger part is fixedly connected to the extrusion plate, and a mounting seat is slidably connected to the connecting seat through a limiting part. The extrusion plate is slidably connected to the mounting seat through an adapter plate; And a butting block is installed on the frame, and the butting block intermittently butts against the trigger part.

[0011] Further, the protection buffer includes a connecting plate fixedly connected to the bottom of the carrier table. A protection plate is fixedly connected to the bottom of the connecting plate. The protection plate is slidably connected to the connecting seat through a buffer groove, and multiple buffer springs are further provided between the protection plate and the buffer groove.

[0012] Furthermore, a return spring is arranged between the connecting plate and the mounting seat, and the elastic force of the return spring drives the extrusion plate away from the metal part.

[0013] Furthermore, a gathering space is formed between the pad, the two protection buffer members, and the two extrusion protection parts, and a cleaning part is slidably connected inside the gathering space.

[0014] Furthermore, a positioning frame is fixedly connected between the two connecting seats, and a power mechanism for driving the cleaning part to slide in the gathering space is arranged between one of the protective buffer members and the positioning frame.

[0015] Furthermore, the power mechanism includes a reciprocating screw and a connecting rod rotatably connected to the positioning frame, the reciprocating screw is threadedly connected to the cleaning part, and the connecting rod and the reciprocating screw are transmission connected via an intermittent clamping part; a linkage rod is rotatably connected to the connecting seat, and the linkage rod and the connecting rod are transmission connected via a synchronization unit; a spur gear is installed on the linkage rod, and a rack is fixedly connected to the protective plate, and the rack is meshed with the spur gear.

[0016] Furthermore, the intermittent clamping portion includes a clamping slot provided on the connecting rod, and a wedge-shaped clamping rod is slidably connected to the reciprocating screw rod via a positioning spring, and the elastic force of the positioning spring drives the wedge-shaped clamping rod to be clamped in the clamping slot.

[0017] Furthermore, the cleaning part comprises a mounting plate, a driving frame is fixedly connected to the mounting plate, the reciprocating screw is threadedly connected to the driving frame; and a cleaning brush is mounted on the mounting plate through an elastic unit.

[0018] Furthermore, blocking plates are fixedly connected to both sides of the bearing platform, and the frame is provided with adapting grooves adapted to the blocking plates.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the casement window processing metal cutting equipment, more specifically, when the metal cutting equipment is used, the metal piece is mounted on the processing frame, and then the power cylinder is started to drive the carrier to move downward, and the carrier drives the cutting mechanism to move downward to a predetermined position, and then the cutting mechanism is started to cut the metal piece. During the downward movement of the carrier, an outer protective space is formed between the protective buffers on both sides, which can effectively prevent high-temperature waste chips from splashing and can protect the staff.

[0020] Meanwhile, during the downward movement of the carrier table, the cushioning protection member and the extrusion protection portion drive the backing plate to move downward. The two extrusion protection portions and the backing plate form an inner protection space on the outer side of the metal part.

[0021] Furthermore, when the carrier table moves downward, during the process of the extrusion protection portion approaching the metal part to form the inner protection space, the metal part will be passively fixed, avoiding the situation of the metal part shaking during cutting.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 12, the present invention provides a technical solution: a metal cutting device for processing flat windows, including a frame 1 and a working frame 2 installed on the frame 1. A bearing table 3 is slidably connected to the working frame 2 through a power cylinder 4. A cutting mechanism 5 is installed on the bearing table 3. A metal piece 16 to be cut is installed on the working frame 2 below the cutting mechanism 5. Protective mechanisms are arranged on both sides of the cutting mechanism 5, and a protective space is formed by the two protective mechanisms; the protective mechanism includes a backing plate 7. Connecting seats 6 are installed on both sides of the backing plate 7. A protective buffer member 9 is arranged between the bearing table 3 and the connecting seat 6. And each connecting seat 6 is connected to the backing plate 7 through an extrusion protection part 8.

[0028] Specifically, the metal cutting device for processing flat windows includes a frame 1 and a working frame 2 installed on the frame 1. A plurality of support members are arranged at the bottom of the frame 1. The support members can improve the stability of the cutting device during operation, and improve the cutting quality of the metal piece 16 from the side, with better effects. A bearing table 3 is slidably connected to the working frame 2 through a power cylinder 4. A cutting mechanism 5 is installed on the bearing table 3. The cutting mechanism 5 is a prior art, and its structure and working principle will not be described in detail here. At the same time, a cutting groove is opened on the frame 1, and the cutting groove is adapted to the cutting mechanism 5 to meet the cutting requirements of the metal piece 16.

[0029] A metal piece 16 to be cut is installed on the working frame 2 below the cutting mechanism 5. Protective mechanisms are arranged on both sides of the cutting mechanism 5. The structures and working principles of the two protective mechanisms are the same. Only one of them will be described in detail here, and the other will not be elaborated. A protective space is formed by the two protective mechanisms. The protective space is adapted to the operation of the cutting mechanism 5 and will not interfere with the cutting operation of the cutting mechanism 5. Since the protective space can protect the cutting mechanism 5 in all aspects, it can effectively prevent the high-temperature waste chips from splashing during the cutting operation of the cutting mechanism 5.

[0030] The protective mechanism includes a backing plate 7. Specifically, the backing plate 7 is made of high-temperature resistant metal material, which can effectively protect the metal piece 16. Connecting seats 6 are installed on both sides of the backing plate 7. Specifically, the structures and working principles of the two connecting seats 6 are the same. Only one of them will be described here in the same way. A protective buffer member 9 is arranged between the bearing table 3 and the connecting seat 6. The material of the protective buffer member 9 is also a high-temperature resistant material. Specifically, an outer protective space is formed between the two protective buffer members 9, which can effectively prevent the high-temperature waste chips from splashing and protect the staff.

[0031] Meanwhile, each connecting seat 6 is connected to the backing plate 7 through the extrusion protection part 8. That is, during the stroke when the servo cylinder drives the carrier table 3 to move downward so that the cutting mechanism 5 performs cutting operations on the metal part 16, the two sides of the metal part 16 are fixed through the extrusion protection part 8. In cooperation with the extrusion of the backing plate 17 on the metal part 16, it can avoid the situation that the metal part 16 shakes during the cutting operation, thereby greatly improving the cutting quality of the metal part 16. Moreover, the extrusion protection part 8 fixes the metal part 16 completely passively during the process of the carrier table 3 driving the cutting mechanism 5 to move downward and preparing to perform cutting operations on the metal part 16, without using a separate drive source to drive the fastening mechanism to fix the metal part 16. Not only is the reliability effectively improved, but also the cost can be greatly saved and the energy consumption can be reduced. At the same time, the two extrusion protection parts 8 and the backing plate 7 form an inner protection space on the outside of the metal part 16. At this moment, during the process of the cutting mechanism 5 performing cutting operations on the metal part 16, the inner protection space can effectively prevent high-temperature waste chips from splashing onto the surface of the metal part 16, achieving the effect of protecting the metal part 16 from being damaged.

[0032] More specifically, when the metal cutting device is in use, the metal part 16 is installed on the processing rack, and then the power cylinder 4 is started to drive the bearing platform 3 to move downward. After the bearing platform 3 drives the cutting mechanism 5 to move downward to a predetermined position, the cutting mechanism 5 is started to perform a cutting operation on the metal part 16. During the downward movement of the bearing platform 3, an outer protection space is formed between the two side protection and buffer members 9, which can effectively prevent high-temperature waste chips from splashing and can protect the staff. At the same time, during the downward movement of the bearing platform 3, the cushion plate 7 is driven to move downward through the protection and buffer members 9 and the extrusion protection parts 8. The two extrusion protection parts 8 and the cushion plate 7 form an inner protection space on the outer side of the metal part 16 (only leaving enough space for the cutting mechanism 5 to perform the cutting operation). At this moment, during the process of the cutting mechanism 5 performing a cutting operation on the metal part 16, the inner protection space can effectively prevent high-temperature waste chips from splashing onto the surface of the metal part 16, avoid high-temperature waste chips falling on the surface of the metal part 16 at a relatively high temperature, and protect the metal part 16 from being damaged. Further, when the bearing platform 3 moves downward, during the process of the extrusion protection part 8 approaching the metal part 16 to form the inner protection space, the metal part 16 will be passively fixed, avoiding the situation of the metal part 16 shaking during cutting. While greatly improving the cutting quality of the metal part 16, since the extrusion protection part 8 fixes the metal part 16 completely by using the downward movement of the bearing platform 3 driving the cutting mechanism 5 to prepare for the cutting operation on the metal part 16, without using a separate driving source and fastening mechanism to fix the metal part 16, not only the reliability is effectively improved, but also the cost can be greatly saved and the energy consumption can be reduced. Thus, it can be seen that the cutting device can improve the working effect while ensuring the cutting quality, and can also effectively reduce the cost and energy consumption, with excellent results.

[0033] In the embodiments provided by the present invention, the extrusion protection part 8 includes an extrusion plate 81. The backing plate 7 is slidably connected to the extrusion plate 81 through a connection unit 10. Specifically, the connection unit 10 includes a support rod fixedly connected to the extrusion plate 81, and a chute adapted to the support rod is provided on the backing plate 7. The support rod is slidably connected to the backing plate 7 through the chute. At this moment, when the extrusion plate 81 slides horizontally, it will drive the support rod to slide horizontally on the backing plate 7. When the extrusion plate 81 slides vertically, under the restriction of the support rod and the chute, it will drive the backing plate 7 to slide vertically together, which can adjust the state of the backing plate 7 to meet the working needs. A trigger part is fixedly connected to the extrusion plate 81. Specifically, the trigger part includes a connecting frame 83 fixedly connected to the extrusion plate 81, and a force-receiving block 84 is fixedly connected to the connecting frame 83, and the force-receiving block 84 is a wedge-shaped block. And an installation seat 86 is slidably connected to the connecting seat 6 through a limiting part 14. Specifically, when the limiting part 14 includes a trapezoidal block 141 fixedly connected to the installation seat 86, a trapezoidal groove adapted to the trapezoidal block 141 is provided on the connecting seat 6, and the trapezoidal block 141 is slidably connected in the trapezoidal groove. Specifically, a limiting spring 142 is provided between the trapezoidal block 141 and the trapezoidal groove, and the elastic force of the limiting spring 142 drives the installation seat 86 to be located at the bottom of the connecting seat 6. The extrusion plate 81 is slidably connected to the installation seat 86 through a connecting plate 82, so that the state of the extrusion plate 81 can be adjusted according to metal parts 16 of different sizes. And a contact block 15 is installed on the frame 1, and the contact block 15 is intermittently in contact with the trigger part.

[0034] When the carrier table 3 moves downward, it drives the protective buffer member 9 to move downward. Specifically, it will drive the backing plate 7 to move downward together through the protective buffer member 9 and the extrusion protection part 8, so that the backing plate 7 abuts against the metal part 16, and the surface of the metal part 16 is covered by the backing plate 7. At this time, an inner protection space is formed outside the metal part 16 by the two extrusion protection parts 8 and the backing plate 7, preventing high-temperature waste chips from falling on the surface of the metal part 16 at a relatively high temperature, and achieving the effect of protecting the metal part 16 from being damaged. When the extrusion plate 81 does not contact the frame 1 during the downward movement, the abutting block 15 and the stress block 84 come into contact first. Therefore, the stress block 84 will drive the extrusion plate 81 to slide toward the metal part 16 through the connecting frame 83 to limit the position of the metal part 16. During the above process, due to the large elastic force of the limiting part 14, when the abutting block 15 abuts against the stress block 84, the stress block 84 can only drive the extrusion plate 81 to move toward the side close to the metal part 16 through the connecting frame 83. When the carrier table 3 continues to move downward, at this time, when the extrusion plate 81 abuts against the metal part 16 and cannot move, the mounting seat 86 will slide on the connecting seat 6 through the limiting part 14. That is, when the extrusion plate 81 stops sliding, the carrier table 3 will still drive the cutting mechanism 5 to move downward. At this time, the protective buffer member 9 is deformed to meet the cutting requirements of the metal part 16. And when the carrier table 3 continues to move, the side surface of the stress block 84 is continuously extruded under the action of the limiting part 14 and the like to improve the stability of the metal part 16 during cutting. And a relief groove 61 is provided at the bottom of the connecting seat 6 to facilitate the avoidance of the connecting frame 83.

[0035] In the embodiment provided by the present invention, the number of the abutting blocks 15 is the same as the number of the stress blocks 84. An adjusting member 18 is provided on the frame 1. The adjusting member 18 is used to drive the abutting blocks 15 on both sides to move toward each other to adjust the states of the two abutting blocks 15 according to the size of the metal part 16. Specifically, the adjusting member 18 includes a guide plate, and the abutting blocks 15 on the same side are connected by the guide plate. A bidirectional lead screw is rotatably connected to the frame 1, and the two guide plates are respectively threadedly connected to both sides of the bidirectional lead screw, and the states of the two abutting blocks 15 can be adjusted according to the size of the metal part 16 to better meet the fixing requirements of the metal part 16.

[0036] In the embodiment provided by the present invention, the protective buffer member 9 includes a connecting plate 91 fixedly connected to the bottom of the bearing platform 3. A protective plate 92 is fixedly connected to the bottom of the connecting plate 91. The protective plate 92 is slidably connected to the connecting seat 6 through a buffer groove 94, and a plurality of buffer springs 93 are further arranged between the protective plate 92 and the buffer groove 94. Preferably, a positioning unit is arranged between the protective plate 92 and the connecting seat 6 to ensure that the protective plate 92 does not disengage from the connecting seat 6. When the bearing platform 3 moves downward, the connecting seat 6 will be driven to move downward together through the protective plate 92. After the connecting seat 6 abuts against the frame 1, the protective plate 92 will slide inside the buffer groove 94 at this moment, and then compress the buffer springs 93 to meet the continuous downward movement of the bearing platform 3, and use the cutting mechanism 5 to perform cutting operations on the metal part 16 to meet the working requirements.

[0037] In the embodiment provided by the present invention, a return spring 85 is arranged between the connecting plate 82 and the mounting seat 86, and the elastic force of the return spring 85 drives the pressing plate 81 away from the metal part 16. At this moment, when the cutting operation of the metal part 16 is completed and the bearing platform 3 moves upward by a certain stroke, the abutting block 15 will stop contacting the stress block 84 at this time. Under the action of the elastic force of the return spring 85, the pressing plate 81 releases the restriction on the metal part 16 to facilitate the conveying of the metal part 16. Conveying members 19 for conveying the metal parts 16 are arranged on both sides of the frame 1. The conveying members 19 are prior art, and their structures and working principles will not be described in detail here. When the pressing plate 81 contacts and restricts the metal part 16, the conveying members 19 can be started to perform conveying operations on the metal part 16.

[0038] In the embodiment provided by the present invention, an aggregation space is formed between the backing plate 7 and the two protective buffer members 9 and the two extrusion protection parts 8. Specifically, this aggregation space can collect the waste chips generated after the cutting of the metal part 16. As is well known, most of the waste chips will fly to the front and rear sides of the cutting mechanism 5 during the cutting process. However, both the front and rear sides of the cutting mechanism 5 are blocked by the protective buffer members 9. At this moment, the flying waste chips will be blocked by the protective buffer members 9 and fall into the aggregation space, thereby being able to collect the waste chips generated after the cutting of the metal part 16 and avoiding the random flying of the waste chips to ensure that the cutting station is in a clean state. And a cleaning part 11 is slidably connected inside the aggregation space. By setting the cleaning part 11, the waste chips inside the aggregation space can be cleaned in time to reduce the accumulation of waste chips.

[0039] In the embodiments provided by the present invention, a positioning frame is fixedly connected between two connecting seats 6. A power mechanism 12 for driving the cleaning part 11 to slide in the gathering space is arranged between one of the protective buffer parts 9 and the positioning frame. By setting the power mechanism 12, power can be provided for the sliding of the cleaning part 11, thereby improving the cleaning efficiency of the cleaning part 11 and having an excellent use effect. The power mechanism 12 includes a reciprocating lead screw 121 rotatably connected to the positioning frame and a connecting rod 126. The reciprocating lead screw 121 is threadedly connected to the cleaning part 11, and the connecting rod 126 is drivingly connected to the reciprocating lead screw 121 through an intermittent clamping part 127. The pitch on the reciprocating lead screw 121 is designed according to the working needs, and it can be ensured that within a certain stroke of the rotation of the reciprocating lead screw 121, the cleaning part 11 moves back and forth inside the gathering space, and can be reset after cleaning the waste chips located inside the gathering space. A linkage rod 122 is rotatably connected to the connecting seat 6, and the linkage rod 122 is drivingly connected to the connecting rod 126 through a synchronization unit 125. A spur gear 124 is installed on the linkage rod 122, and a rack 123 is fixedly connected to the protective plate 92. The rack 123 meshes with the spur gear 124. Specifically, during the use process, when the carrier 3 moves downward until the connecting seat 6 abuts against the frame 1, and then the carrier 3 continues to move downward, at this moment, the protective plate 92 will slide inside the buffer groove 94, that is, at this moment, the rack 123 meshes with the spur gear 124 to drive the spur gear 124 to rotate, and further drives the connecting rod 126 to rotate through the synchronization unit 125. However, at this moment, the connecting rod 126 is connected to the reciprocating lead screw 121 through the intermittent clamping part 127, that is, the reciprocating lead screw 121 cannot rotate at this moment, that is, the cleaning part 11 is in a static state. On the contrary, when the carrier 3 moves upward, when the elastic force of the buffer spring 93 drives the protective plate 92 to move away from the connecting seat 6, the rack 123 meshes with the spur gear 124 to drive the spur gear 124 to rotate, and further drives the connecting rod 126 to rotate through the synchronization unit 125. At this moment, the connecting rod 126 will drive the reciprocating lead screw 121 to rotate through the intermittent clamping part, so as to realize the sliding of the cleaning part 11 to clean the inside of the gathering space.

[0040] Preferably, the synchronization unit 125 is a prior art, and it can be a pulley assembly, etc. When the synchronization unit 125 is a pulley assembly, it includes two pulleys with different diameters. The pulley with a larger diameter is installed on the linkage rod 122, and the pulley with a smaller diameter is installed on the connecting rod 126. The two pulleys are drivingly connected by a belt. At this moment, according to the principle of transmission ratio, when the linkage rod 122 rotates a certain stroke, the rotation amplitude of the connecting rod 126 will be greater than the movement amplitude of the linkage rod 122, further improving the cleaning efficiency of the cleaning part 11 and having an excellent use effect.

[0041] In the embodiment provided by the present invention, the intermittent clamping portion 127 includes a clamping groove 1272 formed on the connecting rod 126, and a wedge-shaped clamping rod 1273 is slidably connected to the reciprocating lead screw 121 through a positioning spring 1273. The elastic force of the positioning spring 1273 drives the wedge-shaped clamping rod 1271 to be clamped in the clamping groove 1272. When the carrying platform 3 continues to move downward at this moment, the protective plate 92 will slide inside the buffer groove 94 at this moment, that is, the rack 123 meshes with the spur gear 124 to drive the spur gear 124 to rotate, and further drives the connecting rod 126 to rotate through the synchronization unit 125. Refer to Figure 11 , when the connecting rod 126 rotates, the wedge-shaped surface of the clamping groove 1272 contacts the wedge-shaped clamping rod 1271. When the wedge-shaped clamping rod 1271 is squeezed, it will squeeze the positioning spring 1273 to retract. Therefore, the reciprocating lead screw 121 cannot be driven to rotate by the wedge-shaped clamping rod 1271, that is, the reciprocating lead screw 121 cannot rotate at this moment, that is, the cleaning part 11 is in a static state. On the contrary, when the carrying platform 3 moves upward, the elastic force of the buffer spring 93 drives the protective plate 92 to move away from the connecting seat 6, the rack 123 meshes with the spur gear 124 to drive the spur gear 124 to rotate, and further drives the connecting rod 126 to rotate through the synchronization unit 125. Refer to Figure 12 , when the connecting rod 126 rotates at this moment, the straight surface of the clamping groove 1272 contacts the straight surface of the wedge-shaped clamping rod 1271, and the connecting rod 126 will drive the reciprocating lead screw 121 to rotate through the intermittent clamping part, so as to realize the sliding of the cleaning part 11 to clean the inside of the aggregation space. Therefore, in the stroke of the reset of the protective plate 92, the cutting device can drive the cleaning part 11 to slide inside the aggregation space through the linkage mechanism, so as to realize the aggregation and removal of waste chips, thereby greatly improving the practicability of the cutting device.

[0042] In the embodiment provided by the present invention, the cleaning part 11 includes a mounting plate, on which a driving frame 112 is fixedly connected, and the reciprocating lead screw 121 is threadedly connected to the driving frame 112; and the mounting plate is provided with a cleaning brush 111 through an elastic unit. The elastic unit is a prior art, which can ensure that the cleaning brush 111 better abuts against the aggregated metal parts 16 to improve the cleaning efficiency of the cutting equipment. Preferably, the cleaning brush 111 can be segmented to better adapt to each component in the aggregation space, thereby improving the cleaning efficiency to a certain extent. Further, additional cleaning units can be installed on both sides of the cleaning part 11 through elastic telescopic rods, which can better adapt to the change of the aggregation space to meet the cleaning needs of the cleaning part 11 and avoid the situation that the cleaning part 11 cannot work due to the reduction of the aggregation space. Preferably, a collection box 13 is detachably arranged on the positioning frame. When the cleaning part 11 slides inside the aggregation space, the waste chips can be cleaned into the collection box 13, and the use effect is better, which can greatly improve the practicability of the cutting equipment. Therefore, after the cutting equipment is used for a period of time, the collection box 13 can be disassembled, the waste chips inside the collection box 13 can be poured out, and the inside of the aggregation space can be thoroughly cleaned by using equipment such as dust suction in the prior art.

[0043] In the embodiment provided by the present invention, sealing plates 17 are also fixedly connected to both sides of the bearing table 3, and an adaptation groove adapted to the sealing plates 17 is provided on the frame 1. When the bearing table 3 moves downward, the sealing plates 17 are slidably connected to the frame 1 through the adaptation groove. By setting the sealing plates 17, the sealing performance of the cutting mechanism 5 during the cutting operation can be further improved, and the situation of waste chips splashing onto the frame 1 can be further reduced.

[0044] In another embodiment provided by the present invention, extension pages are also provided on the side wall of the protection plate 92, and mounting grooves adapted to the extension pages are also provided on the connection seat 6. The function of the extension pages is the same as that of the sealing plates 17, further playing a sealing effect to prevent waste chips from splashing.
