Description

Technical Field

[0001] The present invention relates to the technical field of fixing and cutting plastic suction parts, and specifically provides a fixing and cutting tooling for plastic suction parts. Background Technique

[0002] Plastic suction is a plastic processing technology. The main principle is to heat and soften a flat plastic hard sheet, then use vacuum adsorption on the surface of the mold, and form it after cooling. It is a technical process applied in various industries. When tubular plastic suction parts are formed, there will be extra scraps at the edges of the plastic suction parts. Therefore, it is necessary to cut them according to certain dimensions according to production requirements.

[0003] A disclosed rapid cutting device for plastic suction parts in an existing patent (Publication No.: CN219806165U) includes a fixed base. A guiding and positioning assembly is arranged at the top of the fixed base. The guiding and positioning assembly includes two strip-shaped placing blocks, two gantry plates and two fixed clamping blocks. A cutting tool is arranged above the fixed base. Through the design of the guiding and positioning assembly, after placing the tubular plastic suction part on the two strip-shaped placing blocks, the user adjusts the cutting position with reference to the scale on the strip-shaped placing block, operates the electric telescopic rod until the tubular plastic suction part is clamped and fixed between the strip-shaped placing block and the fixed clamping block, operates the driving motor to drive the cutting tool to rotate, and at the same time operates the hydraulic cylinder to drive the mounting plate to move downward until the cutting tool realizes the cutting work on the tubular plastic suction part. This method effectively avoids situations such as angular deviation of the tubular plastic suction part during cutting and ensures the quality after cutting.

[0004] However, the above technical solution still has certain defects. The above technical solution cuts the plastic suction part with a cutting tool, and the cutting tool rotates rapidly during the cutting process, resulting in a semi-molten state due to friction at the contact position between the cutting tool and the plastic suction part, thus causing the cutting surface to be uneven, and the cutting tool cannot be adjusted and adapted according to different plastic suction parts. Therefore, a fixing and cutting tooling for plastic suction parts is proposed. Summary of the Invention

Two pull rods are fixedly connected to the side of the pressing plate close to the guide rails, and the positions of the two pull rods are respectively close to the two guide rails. The bottom end of each pull rod is fixedly connected with a first convex block, and the top end of each pull rod is fixedly connected with a second convex block. The first convex block and the second convex block are slidably connected to the inner wall of the guide rail.

[0008] As a preferred technical solution, a group of air exhaust ports are respectively opened on both sides of the bottom plate. The inner wall of each air exhaust port is rotatably connected with a group of impellers. Two motors are fixedly connected to the inner wall of the bottom plate, and the output ends of each motor are respectively coaxially fixed to the end of a group of impellers.

[0009] As a preferred technical solution, a group of downward - pressing springs are respectively fixedly connected to the inner wall of each group of frames, and the bottom ends of each group of downward - pressing springs are respectively fixedly connected to the top end of a group of connecting blocks.

[0010] As a preferred technical solution, multiple positioning columns are fixedly connected to the top end of the lower template.

The side ventilation holes on the inner wall of the multiple lower templates are interconnected.

[0011] As a preferred technical solution, a group of carbon strips are respectively slidably connected to the inner wall of each group of sliding strips.

[0013] As a preferred technical solution, each group of the cutting mechanisms further includes two groups of guard plates, and the guard plates are fixedly connected to the inner wall of the fixed plate.

[0014] As a preferred technical solution, a pressure bar is slidably connected to the inner wall of the sliding bar, a plurality of downward pressing seats are fixedly connected to the top of the pressure bar, the top of the downward pressing seats extends to the outside of the sliding bar, and a plurality of pulleys are respectively rotatably connected to the top of each group of the downward pressing seats, and the pulleys are attached to the bottom end of the pressing frame.

[0015] In summary, the present invention mainly has the following beneficial effects: 1. In the present invention, the abutting frame pushes a plurality of metal heating wires downward, so that the metal heating wires pull the metal conductive blocks, thereby enabling the sliding bar to drive the slider to slide. The metal heating wires are pushed by the abutting frame and recessed downward into the fixed plate, so that the metal heating wires come into contact with the plastic suction piece. The metal heating wires are cut by means of heat melting. The temperature of the metal heating wires is relatively high, and the metal heating wires move vertically downward, so that the cut part of the plastic suction piece will not appear in a semi-melted state, making the cut part of the plastic suction piece relatively round and smooth. And for different plastic suction pieces, the distance between the metal heating wires can be changed by pushing the metal conductive blocks to slide inside the sliding bar, and the number of metal heating wires can be reduced or increased, so as to adapt to different plastic suction pieces; 2. In the present invention, during the process of the hydraulic rod pushing the pressing plate up or down, the first convex block and the second convex block slide inside the guide rail, so that the pull rod and the pressing plate flip during the rising process, and drive the fixed tooling to open and close during the rising or falling process of the pressing plate, increasing the degree of automation in the use process of the whole tooling and improving the convenience. The side ventilation holes opened on the side walls of the multiple lower templates are in a mutually connected state, and the bottom ventilation holes communicate with the inner wall of the bottom plate. The motor drives the impeller to rotate, so that the impeller discharges the air inside the bottom plate through the air outlet. The outside air enters the inside of the lower template through the side ventilation holes and then enters the inside of the bottom plate through the bottom ventilation holes. These airflows pass through the surface of the plastic suction piece during the above process, so as to cool the just-produced plastic suction piece during the cutting process; 3. After the plastic suction piece is clamped between the fixed plate and the lower template in the present invention, the frame continues to descend, causing the downward pressure spring to be compressed. At this time, the pressing frame presses against the outer wall of the pulley, applying a downward pressure to the pulley, so that the pressing strip tightly presses against the top of the metal conductive block, preventing the metal slider from shifting during cutting. After cutting is completed, the abutting frame separates from the metal heating wire, and the tension spring rebounds to push the sliding strip back to its original position, keeping the metal heating wire always in a taut state and preventing the metal heating wire from accidentally contacting the plastic suction piece in a relaxed state and causing damage to the plastic suction piece. During the process of the abutting frame pushing down the metal heating wire, the metal heating wire fits against the outer wall of the guard plate, and the outer wall of the guard plate is relatively round, avoiding wear between the metal heating wire and the inner wall of the fixed plate during cutting. The metal conductive block slides and fits against the side wall of the carbon strip, so the metal conductive block can obtain power supply through the carbon strip at different positions inside the sliding strip.

[0018] 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. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and cannot be understood as a limitation to the present invention.

[0019] Next, according to the overall structure of the present invention, its embodiments will be described.

[0020] A fixing and cutting tooling for plastic suction parts, as Figures 1 to 12 shown, includes an outer fixing seat 1. The outer fixing seat 1 includes a bottom plate 101. A set of hydraulic rods 107 are respectively rotatably connected to both sides of the bottom plate 101. The tops of the two sets of hydraulic rods 107 are rotatably connected to a pressing plate 103. A plurality of fixing toolings 2 are fixedly connected between the pressing plate 103 and the bottom plate 101; Each set of the fixing tooling 2 includes a lower template 201 and a connecting frame 207. A plurality of frames 208 are fixedly connected to the top of the connecting frame 207. The plurality of frames 208 are fixedly connected to the bottom end of the pressing plate 103. A plurality of connecting blocks 206 are slidably connected to the inner wall of the connecting frame 207. The bottom ends of the plurality of connecting blocks 206 are fixedly connected to a pressing frame 205. A plurality of sliding columns 204 are slidably sleeved on the inner wall of the pressing frame 205. The bottom ends of the plurality of sliding columns 204 are fixedly connected to a fixed plate 203. The bottom end of the connecting frame 207 is fixedly connected to an abutting frame 210. Two cutting mechanisms 3 are slidably connected to the top end of the fixed plate 203. The two cutting mechanisms 3 are vertically and crosswise arranged above the fixed plate 203; The cutting mechanism 3 includes two groups of sliding bars 301. The two groups of sliding bars 301 are respectively located on both sides of the fixed plate 203. The bottom ends of each group of sliding bars 301 are respectively fixedly connected with multiple groups of sliders 302. The sliders 302 are slidably connected to the top end of the fixed plate 203. Multiple groups of metal conductive blocks 304 are slidably connected to the inner wall of one group of sliding bars 301. The side walls of each group of metal conductive blocks 304 are respectively fixedly connected with a group of metal heating wires 305. The ends of each group of metal heating wires 305 are respectively fixedly connected with another group of metal conductive blocks 304. The other group of metal conductive blocks 304 are slidably connected to the inner wall of the other group of sliding bars 301.

[0021] The hydraulic rod 107 drives the pressing plate 103 to move up and down, so that the pressing plate 103 drives the connecting frame 207 to move up and down through the frame 208. During cutting, the plastic suction piece to be cut is placed inside the lower template 201. During the downward movement of the connecting frame 207, the fixed plate 203 descends and presses on the edge of the plastic suction piece. As the connecting frame 207 continues to descend, the connecting frame 207 compresses the downward pressing spring 209, and drives the abutting frame 210 to descend during the downward movement of the connecting frame 207, so that the abutting frame 210 pushes the multiple groups of metal heating wires 305 downward, causing the metal heating wires 305 to pull the metal conductive blocks 304, thereby causing the sliding bars 301 to drive the sliders 302 to slide. The metal heating wires 305 are pushed by the abutting frame 210 and sink downward into the fixed plate 203, so that the metal heating wires 305 contact the plastic suction piece, causing the contact position between the plastic suction piece and the metal heating wires 305 to melt, realizing the function of cutting the plastic suction piece. The metal heating wires 305 are cut by the hot melting method. The temperature of the metal heating wires 305 is relatively high, and the metal heating wires 305 move vertically downward, so the cut part of the plastic suction piece will not appear in a semi-melted state, making the cut part of the plastic suction piece relatively round and smooth. And for different plastic suction pieces, the distance between the metal heating wires 305 can be changed by pushing the metal conductive blocks 304 to slide inside the sliding bars 301. By pushing the metal conductive blocks 304 out of the sliding bars 301, the number of metal heating wires 305 can be reduced, and conversely, the number of metal heating wires 305 can be increased, so as to adapt to different plastic suction pieces.

[0022] Please refer specifically to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 12, on one side of the bottom plate 101, two groups of guide rails 102 are fixedly connected. On the side of the pressing plate 103 close to the guide rails 102, two groups of pull rods 104 are fixedly connected, and the positions of the two groups of pull rods 104 are respectively close to the two groups of guide rails 102. At the bottom end of each pull rod 104, a first convex block 105 is fixedly connected, and at the top end of each pull rod 104, a second convex block 106 is fixedly connected. The first convex block 105 and the second convex block 106 are slidably connected to the inner wall of the guide rail 102. On both sides of the bottom plate 101, a set of air vents 108 are respectively opened. Inside the inner wall of each air vent 108, an impeller 109 is rotatably connected. Inside the inner wall of the bottom plate 101, two groups of motors 110 are fixedly connected. The output ends of each group of motors 110 are coaxially fixed to the end of a group of impellers 109 respectively. Inside the inner wall of each group of frames 208, a set of downward pressure springs 209 are fixedly connected. The bottom ends of each group of downward pressure springs 209 are respectively fixedly connected to the top end of a group of connecting blocks 206. On the top end of the lower template 201, multiple positioning columns 202 are fixedly connected. On the top end of the fixing plate 203, positioning holes that match the positioning columns 202 are opened. At the bottom end of the lower template 201, a bottom ventilation hole 211 is penetrated and opened. On the side wall of the lower template 201, multiple side ventilation holes 212 are opened. The side ventilation holes 212 inside the inner walls of the multiple lower templates 201 communicate with each other.

[0023] During the process of the hydraulic rod 107 pushing the pressing plate 103 to rise, the pressing plate 103 drives the first convex block 105 and the second convex block 106 to slide inside the guide rail 102 through the pull rod 104. When the second convex block 106 slides to the bending part inside the guide rail 102, the first convex block 105 continues to slide along the guide rail 102, so that the pull rod 104 and the pressing plate 103 are flipped to the Figure 2 state in []. The side ventilation holes 212 on the side walls of the multiple lower templates 201 are in a mutually connected state, and a bottom ventilation hole 211 is penetrated and opened at the bottom end of the lower template 201. The bottom ventilation hole 211 communicates with the inner wall of the bottom plate 101. The motor 110 drives the impeller 109 to rotate, so that the impeller 109 discharges the air inside the bottom plate 101 through the air vent 108 out of the bottom plate 101, and the outside air enters the inside of the lower template 201 through the side ventilation holes 212 and then enters the inside of the bottom plate 101 through the bottom ventilation hole 211. These airflows pass through the surface of the plastic suction part during the above process, so as to cool the just-produced plastic suction part during the cutting process.

[0024] Please refer specifically to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 ,Figure 11 Inside the inner wall of each sliding bar 301, a set of carbon strips 306 are respectively slidably connected. The metal conductive block 304 is slidably attached to the side wall of the carbon strip 306. At both ends of the carbon strip 306, a set of tab ears 307 are respectively fixedly connected. On the side wall of the carbon strip 306, two sets of spring pieces 308 are fixedly connected. The other side of the spring piece 308 is fixedly connected to the inner wall of the sliding bar 301. On the side wall of each slider 302, a set of tension springs 303 are respectively fixedly connected. The end of the tension spring 303 is fixedly connected to the top end of the fixed plate 203. Each cutting mechanism 3 further includes two sets of guard plates 312. The guard plates 312 are fixedly connected to the inner wall of the fixed plate 203. A pressure strip 309 is slidably connected to the inner wall of the sliding bar 301. At the top end of the pressure strip 309, multiple sets of downward pressing seats 310 are fixedly connected. The top end of the downward pressing seat 310 extends to the outside of the sliding bar 301. At the top end of each downward pressing seat 310, multiple sets of pulleys 311 are respectively rotatably connected. The pulley 311 is attached to the bottom end of the pressing frame 205.

[0025] After the fixed plate 203 and the lower template 201 clamp the plastic suction part, the frame 208 continues to descend, causing the downward pressing spring 209 to be compressed. At this time, the pressing frame 205 presses against the outer wall of the pulley 311, applying a downward pressure to the pulley 311, so that the pressure strip 309 tightly presses against the top end of the metal conductive block 304, preventing the metal slider 302 from displacing during cutting. When the abutting frame 210 pushes the metal heating wire 305 downward, it pulls the sliding bar to slide, causing the pulley 311 to roll on the bottom end of the pressing frame 205. After the abutting frame 210 separates from the metal heating wire 305, the tension spring 303 rebounds to push the sliding bar to reset, keeping the metal heating wire 305 always in a taut state. And on the inner wall of the pressing frame 205, there is a guard plate 312, so that during the process of the abutting frame 210 pushing the metal heating wire 305 downward, the metal heating wire 305 fits against the outer wall of the guard plate 312. The outer wall of the guard plate 312 is relatively round, avoiding wear between the metal heating wire 305 and the inner wall of the fixed plate 203 during the cutting process. At both ends of the carbon strip 306, a set of tab ears 307 are respectively provided. The tab ears 307 can be electrically connected to an existing power adapter through a wire. And the metal conductive block 304 is slidably attached to the side wall of the carbon strip 306. Therefore, when the metal conductive block 304 slides to different positions inside the sliding bar 301, it can obtain power supply through the carbon strip 306.

[0026] During use, by pushing a plurality of groups of metal heating wires 305 downward through the abutting frame 210, the metal heating wires 305 are caused to pull the metal conductive blocks 304, so that the sliding bar 301 drives the slider 302 to slide. The metal heating wires 305 are pushed by the abutting frame 210 and recessed downward into the fixing plate 203, so that the metal heating wires 305 come into contact with the plastic suction piece. The metal heating wires 305 are cut by means of heat melting. The temperature of the metal heating wires 305 is relatively high, and the metal heating wires 305 move vertically downward, so that the cut part of the plastic suction piece will not appear in a semi-melted state, making the cut part of the plastic suction piece relatively round and smooth. Moreover, for different plastic suction pieces, the distance between the metal heating wires 305 can be changed by pushing the metal conductive blocks 304 to slide inside the sliding bar 301, and the number of metal heating wires 305 can be reduced or increased, so as to adapt to different plastic suction pieces. The parts not involved in this device are the same as or can be implemented by using the prior art.
