Description

Technical Field

[0001] This utility model relates to profile cutting in the field of picture frames and photo frames, and in particular to a 45° profile cutting saw. Background Technology

[0002] A picture frame or photo frame is a rectangular structure with blank space inside to hold a scroll or photograph. It is used to position the four sides of the scroll or photograph and enhance its aesthetics. The production of a picture frame or photo frame requires cutting a 45-degree angle at both ends of the strip of frame material.

[0003] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0004] Under current technology, factories typically use single-blade profile cutting machines for profile cutting, requiring at least two cuts per finished profile. In actual production, the profiles need to be manually flipped to process both ends separately, requiring a large processing space. Furthermore, operators must manually tighten the profiles, control the cutting position, and adjust the cutting angle during cutting, demanding not only high technical skills but also intense concentration. The close proximity of the hands to the cutting surface during processing poses a significant safety risk. Summary of the Invention

[0005] To address the shortcomings of existing technologies, particularly the difficulty in ensuring angular accuracy and low production efficiency during picture frame or photo frame cutting, this application provides a 45° profile cutting saw. This saw uses two cutting saws to simultaneously feed and cut, completing a 45° angle cut at one end of two finished products in a single cutting operation. This improves the speed and accuracy of profile cutting, solving the technical problems associated with picture frame or photo frame cutting.

[0006] The solution adopted by the embodiments of this application to solve the technical problem is:

[0007] The 45° profile cutting saw includes a saw frame, a feeding mechanism, a cutting saw, a discharging mechanism, a limiting mechanism, a pushing mechanism, and a control system.

[0008] A saw cover is installed on the upper part of the saw frame; the feeding mechanism is located at one end of the saw frame, with a feeding slide and a positioning platform. The feeding slide pulls the profile to the positioning platform for feeding the profile before cutting; the discharging mechanism is located at the other end of the saw frame, with a discharging slide whose center is collinear with the center of the feeding slide; the cutting saws are located on the saw frame and are staggered on both sides of the center lines of the discharging and feeding mechanisms. The cutting saws and the center lines of the discharging and feeding mechanisms are all inclined at 45°, and extend open towards the discharging mechanism. The cutting saws are each independently covered by the saw cover; the limiting mechanism is located next to the positioning platform, which abuts the profile against the positioning platform for horizontal positioning of the profile on the positioning platform; the pushing mechanism is located next to the tail end of the discharging mechanism, which pushes the cut profile downwards on the discharging slide; the control system is located on the saw cover and is electrically connected to the feeding mechanism, discharging mechanism, cutting saws, limiting mechanism, and pushing mechanism;

[0009] The two cutting saws cut simultaneously, completing a 45° angle cut at one end of each of the two finished products in a single cutting operation.

The feeding transmission assembly includes a feeding servo motor and a feeding screw. The output end of the feeding servo motor is connected to the feeding screw, which is mounted on the baffles at both ends. The feeding servo motor is fixed at the beginning of the feeding chute. The feeding slide has an L-shaped structure, with its flanges used for profile limiting. A feeding nut is suspended at the center of the bottom of the feeding slide and is screwed to the feeding screw. The feeding vertical clamping assembly is located on the feeding slide. A horizontal clamping assembly is located on one side of the feeding slide and moves with it, used for vertical positioning and fixing of the profile on the feeding slide; a horizontal clamping assembly is located on the other side of the feeding slide and moves with it, used for horizontal positioning and fixing of the profile on the feeding slide; a positioning platform is an L-shaped structure with a 45° angle, located at the end of the feeding slide, used for profile length positioning and cutting operations, and also has wings for profile positioning; a vertical locking assembly is located on one side of the positioning platform, used for vertical positioning and fixing of the profile on the positioning platform;

[0012] The feeding slide and the positioning platform are collinear, and their wing extensions coincide; the feeding vertical clamping assembly and the feeding vertical locking assembly are located on one side of the feeding slide, and the horizontal clamping assembly is located on the other side of the feeding slide.

[0013] Furthermore, the horizontal clamping assembly includes a swing arm, a rotating arm, and rollers;

[0014] One end of the swing arm is rotatably connected to the side of the positioning platform, and the other end is rotatably connected to a rotating arm. A roller is mounted on the outer end of the rotating arm. The roller rolls and extrudes the profile, pressing it against the wing of the feeding slide table to horizontally limit the profile. A spring is provided between the swing arm and the rotating arm so that the roller is attached to the profile.

[0015] Furthermore, the limiting mechanism includes a limiting cylinder, a limiting seat, a limiting slider, a support arm, a roller, a guide rail, and a buffer cylinder;

A support arm is set on the side of the limiting seat, and a roller is mounted on the support arm to roll and compress the profile, pressing the profile against the wing of the positioning table and limiting the profile in the horizontal direction on the positioning table. A buffer cylinder is set at the end of the limiting seat, and the piston of the buffer cylinder presses down on the guide rail to increase the friction.

[0017] Positive effects:

[0018] The technical solutions provided in this application embodiment have at least the following technical effects or advantages:

[0019] 1. Because the embodiments of this application adopt the technical means of setting a positioning platform between the feeding mechanism and the discharging mechanism, the profile is controlled by the control system, avoiding manual adjustment and fastening of the length of the unprocessed profile. This effectively solves the technical problems of difficult cutting accuracy and low production efficiency in the prior art, thereby achieving the technical effect of improving the safety and efficiency in the profile processing process.

[0020] 2. Because the embodiments of this application adopt the technical means of cutting simultaneously with two cutting saws, a 45° angle cut is completed at one end of two finished products in one cutting operation, which effectively solves the technical problems of difficulty in ensuring cutting accuracy and low production efficiency in the prior art. It eliminates the steps of processing the two ends of the unprocessed profile separately and the profile flipping space required for profile processing in the original processing, thereby achieving the technical effect of improving the speed and accuracy of profile cutting processing.

[0021] 3. As this application embodiment adopts the technical means of providing a horizontal clamping component on the side of the feeding slide, one end of the swing arm is rotatably connected to the side of the positioning table, and the other end is rotatably connected to a rotating arm. A roller is assembled on the outer end of the rotating arm. The roller rolls and squeezes the profile, which effectively solves the technical problems of difficulty in ensuring cutting accuracy and low production efficiency in the prior art. The roller can not only improve the stability in the horizontal direction, but also suppress the generation of profile deviation, thereby achieving the technical effect of improving the cutting accuracy of the profile.

[0022] 4. Because the embodiments of this application adopt the technical means of providing a limiting mechanism on the side of the positioning table, the rollers abut against the positioning table, which can horizontally position the profile on the positioning table; effectively solving the technical problems of difficulty in ensuring cutting accuracy and low production efficiency in the prior art. When performing profile cutting operations, the rollers abut against the positioning table to position the profile in the horizontal direction; thereby achieving the technical effect of improving the profile cutting accuracy.

[0023] 5. As this application embodiment adopts the technical means of providing a buffer cylinder in the limiting mechanism, the piston of the buffer cylinder presses down on the guide rail, increasing the friction force of the limiting seat movement, effectively solving the technical problems of difficult to guarantee cutting accuracy and low production efficiency in the prior art, so that when the limiting cylinder pulls the limiting seat to move, it will not cause impact, avoid damaging the profile surface, and thus achieve the technical effect of improving the yield of cutting operations.

[0101] This application provides a 45° profile cutting saw, which solves the problems of low production efficiency and difficulty in ensuring angle accuracy in existing technologies. By using staggered dual cutting saws with synchronous feed during the cutting of picture frames or photo frames, it achieves accurate 45° cutting at both ends of the frame, thus improving production efficiency. In this embodiment, the picture frame or photo frame is referred to simply as a profile.

[0102] According to the instruction manual Figure 1-11 As shown, the 45° profile cutting saw includes a saw frame 100, a feeding mechanism 200, a cutting saw 300, a discharging mechanism 400, a limiting mechanism 500, a pushing mechanism 600, and a control system 700.

[0103] The saw frame 100 is a frame structure used to support the 45° profile cutting saw. A saw cover 110 is provided on the upper part, and a collection bag is provided at the lower part of the saw frame 100 to collect the waste material left after profile cutting.

[0104] The feeding mechanism 200 is located at one end of the saw frame 100 and has a feeding slide 230 and a positioning table 260. The feeding slide 230 moves linearly back and forth to pull the profile to the positioning table 260 for feeding the profile before cutting.

[0105] The discharge mechanism 400 is located at the other end of the saw frame 100 and has a discharge slide 430. The discharge slide 430 is adjacent to the platform 260 and moves linearly back and forth. The profile is discharged after being cut by the discharge slide 430. The center of the discharge slide 430 is collinear with the center of the feeding slide 230. Therefore, the discharge mechanism 400 and the feeding mechanism 200 are located on the same center line.

[0106] There are two cutting saws 300, located on the saw frame 100 and staggered on both sides of the center line of the discharge mechanism 400 and the feeding mechanism 200. The center lines of the cutting saws 300, the discharge mechanism 400 and the feeding mechanism 200 are inclined at an angle of 45° and extend open towards the discharge mechanism 400. The cutting saws 300 are fed synchronously to form 45° cut angles at both ends of the profile, so that the profile can be assembled into a rectangular structure. In this embodiment, the cutting saws 300 are independently covered by saw covers 110.

[0107] The limiting mechanism 500 is located beside the positioning platform 260 and abuts the profile against the positioning platform 260 for horizontal positioning of the profile on the positioning platform 260. When the profile is being cut, the limiting mechanism 500 abuts the profile against the positioning platform 260 for horizontal positioning of the profile.

[0108] The pushing mechanism 600 is located on the side of the tail end of the discharging mechanism 400 and is used to push the cut profiles laterally down on the discharging slide 430. The discharging slide 430 cyclically clamps the profiles.

[0109] The control system 700 is mounted on the saw cover 110 and electrically connected to the feeding mechanism 200, the discharging mechanism 400, the cutting saw 300, the limiting mechanism 500, and the pushing mechanism 600; it controls the length positioning of the profile and the cutting command to carry out the profile cutting operation.

[0110] Two cutting saws (300mm each) cut simultaneously, completing a 45° angle cut at one end of each of the two finished products in a single cutting operation.

[0111] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0112] Because a positioning platform 260 is provided between the feeding mechanism 200 and the discharging mechanism 400, the profile is controlled by the control system, avoiding manual adjustment and tightening of the length of the unprocessed profile, thus improving the safety and efficiency of the profile processing process.

[0113] Because the two cutting saws 300 cut simultaneously, a single cutting operation completes a 45° angle cut at one end of each of the two finished products. This eliminates the need for separate processing of the two ends of the unprocessed profile and the profile flipping space required for profile processing, thus improving the speed and accuracy of profile cutting.

[0114] To ensure the stability of the structure in this embodiment, please refer to the appendix to the specification. Figure 6 , 8 The feeding mechanism 200 includes a feeding transmission assembly 210, a feeding slide 220, a feeding slide table 230, a feeding vertical clamping assembly 240, a horizontal clamping assembly 250, a positioning platform 260, and a feeding vertical locking assembly 270.

[0115] The feeding chute 220 has a U-shaped structure and is located at one end of the saw frame 100. The feeding chute 220 has baffles at both ends and a guide rail at the bottom, which is not shown in the accompanying drawings of this embodiment.

[0116] The feeding transmission assembly 210 includes a feeding servo motor 211 and a feeding screw 212; the output end of the feeding servo motor 211 is connected to the feeding screw 212, the two ends of the feeding screw 212 are mounted on baffles, and the feeding servo motor 211 is fixed at the beginning of the feeding slide 220.

[0117] The feeding slide 230 has an L-shaped structure, and its wing is used for profile limiting. A feeding nut 231 is suspended at the bottom center of the feeding slide 230. The feeding nut 231 is screwed to the feeding screw 212. When the feeding servo motor 211 drives the feeding screw 212 to rotate, the feeding nut 231 pulls the feeding slide 230 to slide linearly along the guide rail to feed the profile.

[0118] The vertical clamping assembly 240 is disposed on one side of the feeding slide 230 and moves with it, and is used to limit and fix the profile in the vertical direction on the feeding slide 230;

[0119] The horizontal clamping assembly 250 is located on the other side of the feeding slide 230 and moves with it. It is used to limit and fix the profile in the horizontal direction on the feeding slide 230 and to hold the profile against the wing of the feeding slide 230.

[0120] The positioning platform 260 is an L-shaped structure with a 45° angle, located at the end of the feed slide 220, used for positioning the profile length and performing cutting operations, and also has wing edges for limiting the profile.

[0121] The feed vertical locking assembly 270 is disposed on one side of the positioning platform 260 and is used to limit and fix the profile in the vertical direction on the positioning platform 260.

[0122] Among them, the center of the feeding slide 230 and the positioning platform 260 are collinear, and their wing extension lines coincide; the feeding vertical clamping assembly 240 and the feeding vertical locking assembly 270 are located on one side of the feeding slide 220, and the horizontal clamping assembly 250 is located on the other side of the feeding slide 220, which facilitates the conveying of the profile.

[0123] To further ensure the stability of the structure in this embodiment, please refer to the appendix to the specification. Figure 4 The horizontal clamping assembly 250 includes a swing arm 251, a rotating arm 252, and a roller 253;

[0124] The swing arm 251 is a structural component. One end is rotatably connected to the side of the positioning platform 260, and the other end is rotatably connected to the rotating arm 252. A roller 253 is mounted on the outer end of the rotating arm 252. The roller 253 rolls and extrudes the profile, pressing it against the wing of the feeding slide 230 to limit the profile horizontally. A spring is provided between the swing arm 251 and the rotating arm 252 so that the roller 253 is attached to the profile.

[0125] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0126] Because a horizontal clamping assembly 250 is provided on the side of the feeding slide 230, one end of the swing arm 251 is rotatably connected to the side of the positioning table 260, and the other end is rotatably connected to the rotating arm 252. A roller 253 is assembled on the outer end of the rotating arm 252. The roller 253 rolls and extrudes the profile. Therefore, the roller 253 can not only improve the stability in the horizontal direction, but also suppress the generation of profile deviation and improve the accuracy of profile cutting.

[0127] As a standard technical option, see the appendix to the instruction manual. Figure 8 The vertical feeding clamping assembly 240 includes a vertical feeding clamping cylinder 241 and a vertical feeding clamping cylinder frame 242.

[0134] The discharge slide 430 is an L-shaped structure with a 45° angle, and its wing is used for profile limiting. A discharge nut 431 is suspended at the bottom center of the feed slide 230. The discharge nut 431 is screwed to the discharge screw 412. When the discharge servo motor 411 drives the discharge screw 412 to rotate, the discharge nut 431 pulls the discharge slide 430 to slide linearly along the guide rail to discharge the profile.

Figure 3 The limiting mechanism 500 includes a limiting cylinder 510, a limiting seat 520, a limiting slider 530, a support arm 540, a roller 550, a guide rail 560, and a buffer cylinder 570.

[0143] The limiting seat 520 has a plate-like structure. A limiting slider 530 is arranged at the lower part of the limiting seat 520 and is mounted on a guide rail 560, which is placed on the saw frame 100. A limiting cylinder 510 is provided on the side of the guide rail 560. The piston of the limiting cylinder 510 is connected to the limiting seat 520 and pulls it to extend and retract. A support arm 540 is provided on the side of the limiting seat 520, and a roller 550 is mounted on the support arm 540 to roll and compress the profile, pressing the profile against the wing of the positioning platform 260, thus limiting the profile horizontally on the positioning platform 260. A buffer cylinder 570 is provided at the end of the limiting seat 520. The piston of the buffer cylinder 570 presses down on the guide rail 560 to increase friction, preventing excessive pushing force from the roller 550 and thus avoiding damage to the profile when the limiting cylinder 510 pulls the limiting seat 520.

[0144] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0145] Because a limiting mechanism 500 is provided on the side of the positioning table 260, and the roller 550 abuts the profile against the positioning table 260, the profile can be horizontally positioned on the positioning table 260. When the profile is being cut, the roller 550 abuts the profile against the positioning table 260 to position the profile horizontally. The roller 550 not only improves the horizontal stability, but also suppresses the profile offset and improves the accuracy of profile cutting.

[0146] Because a buffer cylinder 570 is provided in the limiting mechanism 500, and the piston of the buffer cylinder 570 presses down on the guide rail 560, the buffer cylinder 570 increases the friction force of the limiting seat 520, so that when the limiting cylinder 510 pulls the limiting seat 520 to move, no impact will be caused, thus avoiding damage to the profile surface and improving the yield of the cutting operation.

[0147] To further optimize the structure of this embodiment, please refer to the appendix to the specification. Figure 4 The cutting saw 300 includes a cutting motor 310, a cutting saw blade 320, a cylinder 330, a slider 340, a slide rail 350, and a base 360;

[0148] The 320 cutting saw blade is used to cut profiles, forming a 45° angle at both ends of the profile and assembling it into a rectangular frame;

[0149] The output end of the cutting motor 310 is equipped with a cutting saw blade 320, which drives the cutting saw blade 320 to rotate and perform profile cutting.

[0150] The slider 340 is located at the bottom of the cutting motor 310 and is used for the movement of the cutting motor 310 to feed the cutting.

[0151] The slide rail 350 is used to assemble the slider 340, so that the cutting motor 310 can move linearly.

[0152] The base 360 ​​is a plate-shaped structure used to fix the slide rail 350 on the saw frame 100;

[0153] One end of the cylinder 330 is fixed on the saw frame 100, and the other end is connected to the cutting motor 310, which is used to drive the cutting motor 310 to perform cutting feed along the slide rail 350.

[0154] As a standard technical option, see the appendix to the instruction manual. Figure 6 The pushing mechanism 600 includes a pushing cylinder 610, a pushing cylinder frame 620, and a pushing plate 630;

[0155] A pusher cylinder frame 620 is provided on the side of the end of the discharge slide 420, and the pusher cylinder frame 620 is located on the same side as the discharge vertical locking assembly 450 and the discharge vertical clamping assembly 440. A pusher cylinder 610 is mounted on the pusher cylinder frame 620. The piston end of the pusher cylinder 610 is connected to a pusher plate 630. The pusher plate 630 is a strip plate used to push the cut profile out of the discharge slide 420, which facilitates continuous profile cutting operations.

[0156] The working process of this embodiment:

[0157] After the control system 700 adjusts to the required processing length of the profile, the unprocessed profile is fed into the positioning table 260 through the feeding slide 230. After being positioned at the designated cutting position, the unprocessed profile is clamped, and the control system 700 issues a cutting command. The two cutting saws 300 cut the profile at a 45° angle at one end of the two finished products in one processing cycle. After one processing cycle, the processed profile is sent to the pushing mechanism 600 for unloading through the discharge slide 430. The unprocessed profile continues to advance through the feeding slide 230 to the next designated cutting position. This process is repeated until all the unprocessed profiles are processed.

[0158] In this embodiment, the feeding vertical clamping cylinder 241, the feeding vertical locking cylinder 271, the cylinder 330, the discharging vertical clamping cylinder 441, the discharging vertical locking cylinder 451, the limiting cylinder 510, the buffer cylinder 570, and the pushing cylinder 610 are all connected to the air source.
