Description

Technical Field

[0001] The utility model relates to the technical field of extrusion piece processing devices, in particular to an automatic punching and cutting device for composite extrusion pieces. Background Art

[0002] Extrusion, also known as extrusion molding, is a manufacturing process that involves the process of isobaric quantitative extrusion of materials through the die mouth after they are heated and melted in the extruder, and finally forming a product with uniform cross-section. The process flow is as follows: plastic particles are fed into the barrel and then forced to be pushed toward the head of the extruder under the rotation of the screw. In this process, the originally loose solid raw materials are gradually compacted as they move forward. Thanks to the heating outside the barrel and the friction shear effect between the screw and the inner wall of the barrel, the temperature of the raw materials rises until they melt. The continuous and stable rotation of the screw pushes the molten material to the head position, at which time the material is isobarically extruded and then cooled and shaped to obtain the finished product. The shape of the extruded product is usually consistent with the shape of the die mouth and has a uniform cross-section. For example, the edges of PVC top trim strips, luggage rack longitudinal beams, sunroofs and seat rails in automotive interiors and exteriors are all typical application examples of this process. After these parts are formed, they often need to undergo subsequent processing such as stamping and sawing according to different vehicle models or design requirements.

[0003] However, traditional stamping and sawing equipment are mostly set up independently. When extrusion parts need to undergo these processes, the products must be transferred to the corresponding stamping workstation or sawing workstation in batches. Each workstation needs to be equipped with special equipment and tooling, which not only takes up a lot of workshop space, but also requires two clampings when extrusion parts need to be stamped and sawed continuously. This process is not only time-consuming, but may also introduce more processing errors. Utility Model Content

DETAILED DESCRIPTION

[0042] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0043] An automatic punching device for composite extrusions has a single punching state, a single cutting state and a punching composite state. The punching device comprises: a frame 1, on which a movable moving table 2 is arranged; a punching unit 3, which is arranged on the moving table 2, and the punching unit 3 has a positioning table 4 and a punch 5, the positioning table 4 is used to position the extrusion to be processed, and the punch 5 is movably arranged above the positioning table 4 in the vertical direction, and is used to punch the extrusion; a sawing unit 6, which is arranged on the moving table 2 and is located on the side of the punching unit 3, and the sawing unit 6 has a movable A saw blade 36 is arranged above the movable table 2, and is used for sawing the extruded piece; a central control unit 7 is arranged on the frame 1 and is electrically connected to the punching unit 3 and the sawing unit 6, and is used for controlling the working state of the punching device; when the punching device is in a single punching state, the punch 5 performs a punching operation on the extruded piece and the saw blade 36 does not move; when the punching device is in a single cutting state, the saw blade 36 performs a sawing operation on the extruded piece and the punch 5 does not move; when the punching device is in a punching composite state, the punch 5 and the saw blade 36 successively operate on the extruded piece.

[0044] Based on the above embodiments, an exemplary structure of the present invention is as follows: Figures 1 to 6 As shown, the movement of the mobile platform 2 on the frame 1 can be driven by a servo motor, that is, a screw rod with one end connected to the servo motor is set on the frame 1, the mobile platform 2 is threadedly connected to the screw rod, and the servo motor drives the screw rod to rotate to realize the movement of the mobile platform 2 on the frame 1.

[0045] Before starting work, first select the working state of the punching device through the central control unit 7 according to the processing content. For example, when the extrusion piece only needs to be punched, the central control unit 7 controls the punching unit 3 to start and the sawing unit 6 to turn off, and the punching unit 3 punches the extrusion piece through the punch 5; when the extrusion piece only needs to be sawed, the central control unit 7 controls the sawing unit 6 to start and the stamping unit 3 to turn off, and the sawing unit 6 cuts the extrusion piece through the saw blade 36; when the extrusion piece requires both stamping and sawing operations, the central control unit 7 controls the stamping unit 3 and the sawing unit 6 to move successively, and the stamping unit 3 and the sawing unit 6 are both set on a movable table 2 that can move relative to the frame 1, so as to perform stamping or sawing operations at different positions of the extrusion piece according to needs.

[0046] In the present solution, by simultaneously arranging the punching unit 3 and the sawing unit 6 on one machine platform, and controlling the opening and closing of the punching unit 3 and / or the sawing unit 6 through the central control unit 7, the processing technology of the extrusion part can be selected according to actual needs, which greatly saves the processing space required for the processing of the extrusion part. In addition, when the extrusion part is punched and sawed, there is no need to move the extrusion part, thereby improving the processing accuracy of the extrusion part.

[0047] The punching unit 3 includes: a first support frame 8, which is arranged on the moving platform 2, and a first driving member 9 is arranged on the first support frame 8; a first moving seat 10, which is movably arranged above the positioning platform 4 and connected to the output end of the first driving member 9, and the punch 5 is connected to the first moving seat 10; two first clamping blocks 11 arranged relatively on the positioning platform 4, the two first clamping blocks 11 are both movably arranged on the positioning platform 4 in the horizontal direction and the moving directions are opposite, and the moving directions of the two first clamping blocks 11 are perpendicular to the moving direction of the moving platform 2; two pushing blocks 12, which are connected to the first moving seat 10 and correspond to the first clamping blocks 11 one by one; a support block 13, which is arranged on the positioning platform 4 and is used to extend into the extrusion piece to provide support for the extrusion piece; at least two first limiting columns 14, which are arranged on the positioning platform 4, and the first moving seat 10 is provided with a second limiting column 15 corresponding to the first limiting column 14 one by one, and the first limiting column 14 and the second limiting column 15 are movably abutted against each other to provide a limit for the movement of the first moving seat 10.

[0048] During operation, the first driving member 9 arranged on the first supporting frame 8 drives the first movable seat 10 to move in the direction of the positioning platform 4, thereby driving the punch 5 and the pushing block 12 to move. When the pushing block 12 moves, it pushes the two first clamping blocks 11 to approach each other and press on the side wall of the extrusion, thereby fixing the extrusion on the positioning platform 4. At the same time, the punch 5 moves in the direction of the extrusion to perform a stamping operation on the extrusion. After the first movable seat 10 moves to the first limit column 14 and the second limit column 15 to abut against the punch 5, the punch 5 completes the stamping operation on the extrusion, and the first driving member 9 drives the first movable seat 10 to reset.

[0049] Preferably, the stamping unit 3 also includes a spring arranged between the first clamping block 11 and the positioning platform 4. When the two first clamping blocks 11 are close to each other, the spring is in a stretched state. When the first movable seat 10 drives the pushing block 12 to reset, the spring resets and drives the first clamping block 11 to reset. The first driving member 9 is a cylinder.

[0050] Furthermore, a guide channel 16 is provided in the positioning platform 4 , and the two first pressing blocks 11 are movably provided in the guide channel 16 to provide guidance for the first pressing blocks 11 .

[0051] The two push blocks 12 are each provided with a first inclined surface 17 on one side opposite to the other, and the two first pressing blocks 11 are each provided with a second inclined surface 18 . The first inclined surface 17 corresponds to the second inclined surface 18 one by one and is movable against each other.

[0052] When the first movable seat 10 drives the pushing block 12 to move toward the first pressing block 11 , the first inclined surface 17 and the second inclined surface 18 first contact each other, and the first pressing blocks 11 are pushed closer to each other through the interaction between the first inclined surface 17 and the second inclined surface 18 .

[0053] The sawing unit 6 includes: a fixed seat 19, which is fixedly connected to the movable table 2, and a third inclined surface 20 is arranged on the fixed seat 19; a second driving member 21, which is connected to the third inclined surface 20; a second movable seat 22, which is movably arranged on the third inclined surface 20 and connected to the output end of the second driving member 21, and the second driving member 21 is used to drive the second movable seat 22 to move along the third inclined surface 20; a third driving member 23, which is connected to the second movable seat 22, and a saw blade 36 is connected to the output end of the third driving member 23; two clamping members 24, both of which are arranged on the movable table 2 and are arranged on both sides of the saw blade 36, and the clamping members 24 are used to press on both sides of the extruded member where it needs to be sawed off.

[0054] During operation, the second driving member 21 drives the third driving member 23 to move by driving the second movable seat 22 to move on the third inclined plane 20. When the third driving member 23 moves, it drives the saw blade 36 to move closer to or away from the extruded member. The setting of the third inclined plane 20 is used to prevent the third driving member 23 and the saw blade 36 from interfering with other parts of the punching device when the second movable seat 22 moves. The two clamping members 24 are used to prevent the extruded member from jumping when the saw blade 36 is sawing the extruded member, so as to improve the sawing accuracy of the extruded member. Preferably, the second driving member 21 and the third driving member 23 are both motors.

[0055] The clamping member 24 includes: a second support frame 25; a fourth driving member 26, which is connected to the moving platform 2; and a second pressing block 27, which is movably arranged above the second support frame 25, and the output end of the fourth driving member 26 passes through the moving platform 2 and the second support frame 25 in sequence and is connected to the second pressing block 27.

[0056] During operation, the fourth driving member 26 drives the second pressing block 27 to move toward the extrusion member, so that the second pressing member is pressed on the end surface of the extrusion member to fix the extrusion member. Preferably, the fourth driving member 26 is a cylinder.

[0057] The present solution also includes a storage piece 28, which is arranged on the frame 1 and is located below the movable platform 2. The storage piece 28 is used to store waste generated when the saw blade 36 cuts the extruded piece. The storage piece 28 has: a material receiving channel 29, the material receiving channel 29 has a feeding part 30 and a discharging part 31, the height of the feeding part 30 in the vertical direction is greater than the height of the discharging part 31, and a through groove is provided on the movable platform 2 between the two clamping parts 24, and the through groove is located directly above the feeding part 30; a material receiving frame 32, which is inserted on the frame 1 and is located directly below the discharging part 31.

[0058] During the sawing process of the extruded parts, the generated debris passes through the through groove and falls onto the feed part 30 of the receiving channel 29. Since the height of the feed part 30 is greater than the height of the discharge part 31, the debris that falls into the receiving channel 29 moves to the receiving frame 32 under the action of its own weight.

[0059] The present solution also includes: two first rollers 33 arranged at intervals, both of which are rotatably arranged on the frame 1 and arranged in the vertical direction; two second rollers 34 arranged at intervals, both of which are rotatably arranged on the frame 1 and arranged in the vertical direction, and the second rollers 34 are located on the side of the first rollers 33; an encoder 35, which is arranged on the frame 1 and on one side of the second roller 34, and the encoder 35 is electrically connected to the stamping unit 3, the central control unit and the sawing unit 6, and is used to record the length of the extrusion piece moving.

[0060] During operation, one end of the extruded piece passes through between the two first rollers 33, the two second rollers 34, the punching unit 3 and the sawing unit 6 in sequence, and is driven by other power mechanisms (not shown in the figure) along the Figure 1 Moving from left to right, the two first rollers 33 are used to provide support for the extrusion, and the encoder 35 is used to record the number of revolutions of one of the second rollers 34. The distance moved by the extrusion can be obtained by multiplying the number of revolutions by the circumference of the second roller 34, so as to improve the accuracy of stamping and / or sawing of the extrusion.

[0061] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).
