Description

Technical Field

[0001] The invention relates to the technical field of plastic sheet stamping and forming, in particular to a plastic sheet stamping and forming device. Background Art

[0002] The punching machine drives the flywheel through an electric motor, and drives the crank-connecting rod mechanism through a clutch and transmission gear to make the slider move up and down, driving the stretching die to form the steel plate. The stamping production is mainly for the plate. The design principle of the punching machine is to convert circular motion into linear motion. The main motor outputs power to drive the flywheel, and the clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to achieve the linear motion of the slider. The movement from the main motor to the connecting rod is a circular motion. Through the die, blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion can be made. The punching machine applies pressure to the material to make it plastically deformed and obtain the required shape and precision. Therefore, a set of dies (divided into upper and lower dies) must be used to place the material in between, and the machine applies pressure to make it deform. The reaction force caused by the force applied to the material during processing is absorbed by the punching machine body.

[0003] In the actual production process, the mold may stick together due to high temperature during the plastic sheet stamping process. This is mainly because the plastic becomes sticky at high temperatures and easily adheres to the mold surface, causing the plastic sheet to stick to the mold. Specific reasons include:

[0004] 1. Plastic decomposition due to heat: When plastic is heated at high temperature for too long, it may decompose and deteriorate, losing its original properties, resulting in breakage or fracture during the demolding process, causing mold sticking.

[0005] 2. Uneven cooling: If the feed port of the mold is unbalanced, the plastic will not be easy to cool after being filled into the mold cavity, and the cycle time needs to be extended, which not only affects production efficiency but may also cause the plastic to stick to the mold.

[0006] The adhesive force generated after the stamping plate and the plastic sheet are bonded together may cause the stamping plate to malfunction when it rises. The existing market cannot immediately sense and cut off the power supply for this problem, which may lead to an increase in production costs. In addition, after the plastic sheet is stamped and formed, a part of the formed sheet will be less strong due to prolonged heating, so it is necessary to test the strength of the plastic sheet and eliminate unqualified formed products.

[0019] The present invention has the following beneficial effects:

[0020] 1. By setting the detection component and the power-off component in this device, when the punching machine punches the plastic sheet, the temperature of the mold has a significant impact on the adhesion during the punching process of the plastic sheet. When the temperature of the mold is too high, the plastic sheet may adhere to the mold, resulting in the phenomenon of sticking to the mold. The too high surface temperature of the mold will cause the alloy material to easily adhere to the mold, thus generating the problem of sticking to the mold, making the punching machine and the punching seat stick together due to the plastic adhesion problem. At this moment, the detection component can detect whether an unexpected situation of adhesion occurs, and the power-off component can cut off the power supply of the punching machine to ensure that an emergency response can be made in case of an unexpected situation;

[0021] 2. By setting the detection mechanism, the moving component and the judging mechanism to form a large detection mode in this device. When the punching machine punches normally and no adhesion occurs, but after the plastic sheet is punched and formed, a part of the formed sheet may have a low firmness due to excessive heating. The detection mode is used to detect the firmness of the plastic sheet and eliminate unqualified formed products;

[0022] 3. By setting the induction component and the supporting component, since the plastic sheet is closely attached to the punching seat during punching and its hardness is low due to high temperature, it further causes that the plastic sheet cannot be easily clamped for detection during the detection process. By setting the induction component, when the punching seat is about to move to the detection position, the sheet to be detected is lifted by the supporting component, which is convenient for later detection;

[0023] 4. By setting up a classification mechanism, the qualified products and waste items are screened. Moreover, some sheets may be simultaneously stamped with other materials during the stamping process. After passing the inspection, during the classification process, the degree of adhesion between the adhesives can be preliminarily screened. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1

[0040] Reference Figure 1 - Figure 3, the adjusting component 6 includes a support frame 61, a first lead screw 62, a slide bar 63 and a first motor 64. There are two sets of support frames 61, and each set has two support frames 61. Between one set of support frames 61, the first lead screw 62 is rotatably arranged through a bearing, and the output end of the first motor 64 is fixedly arranged with the first lead screw 62, and the bottom of the first motor 64 is fixedly arranged with the bottom plate 2. Between the other set of support frames 61, the slide bar 63 is fixedly arranged. One side wall of the stamping seat 5 is threadedly connected with the first lead screw 62, and a hole for the slide bar 63 to slide is opened on the other side wall of the stamping seat 5.

[0041] Refer to Figure 4 , the detection component 7 includes positioning side plates 71, a cross bar 72, a rotating convex block 73 and a first switch 74. There are two positioning side plates 71, and both are fixedly arranged with the bottom plate 2. The cross bar 72 is fixedly arranged between the two positioning side plates 71, and the cross bar 72 passes through the inside of the rotating convex block 73 and there is a bearing at the connection with the rotating convex block 73. A return spring is fixedly arranged between the rotating convex block 73 and the positioning. The first switch 74 is fixedly arranged with the bottom plate 2 and is located directly below the rotating convex block 73.

[0042] Refer to Figure 5 - Figure 6 , the power-off component 8 includes a positioning frame 81, a square frame 82, a T-shaped slide plate 83, a half gear 84, a second motor 85, a contact head 86, a vertical plate 87 and a second switch 88. The positioning frame 81 is fixedly arranged with the base 1. The top of the square frame 82 is fixedly arranged with the T-shaped slide plate 83, and a chute for the T-shaped slide plate 83 to slide is opened inside the positioning frame 81. Rack teeth are fixedly arranged on both the upper and lower sides of the inner wall of the square frame 82. The half gear 84 is rotatably arranged on the inner wall of the positioning frame 81 through a bearing, and the half gear 84 extends between the upper and lower sides of the inner wall of the square frame 82 and is meshed with the rack teeth. The second motor 85 is fixedly arranged on one side of the outer wall of the positioning frame 81 and the output end is fixedly arranged with the half gear 84. The contact head 86 is fixedly arranged on one side of the outer wall of the square frame 82. The vertical plate 87 is fixedly arranged with the base 1, and the second switch 88 is fixedly arranged with the vertical plate 87, and the second switch 88 and the contact head 86 are on the same horizontal line.

[0043] In this embodiment: The initial position of the stamping seat 5 is at the top of the support seat 4. A plastic sheet can be placed on the top of the stamping seat 5. When the stamping machine 3 is started to stamp the plastic sheet, the die temperature has a significant impact on the adhesion during the stamping process of the plastic sheet. When the die temperature is too high, the plastic sheet may adhere to the die, resulting in the phenomenon of sticking to the die. The too high surface temperature of the die will cause the alloy material to easily adhere to the die, thus generating the problem of sticking to the die, causing the stamping machine 3 and the stamping seat 5 to stick due to plastic adhesion. At this moment, the detection component 7 can be used to detect whether an accidental adhesion occurs. Under normal circumstances, when the stamping head descends, it will abut against the surface of the rotating convex block 73. During continuous downward pressure, it will provide pressure to drive the rotating convex block 73 to rotate by ninety degrees and touch the first switch 74. When the stamping head does not stick normally, it will disengage from the first switch 74 within a certain period of time (the time can be set according to different stamping machines 3). Assuming the normal situation is two seconds, when adhesion occurs and the stamping head and the stamping seat 5 adhere and cannot be easily separated, at this time, the rotating convex block 73 will continuously abut against or continuously trigger the first switch 74. When the time for triggering the first switch 74 exceeds 2 seconds (the time can be set to 3 seconds), when it reaches the 3rd second, the power-off component 8 is started to cut off the power supply to check the situation to avoid accidents;

[0044] After receiving the signal from the first switch 74, the power-off component 8 starts the second motor 85 to drive the half gear 84 to rotate. The half gear 84 drives the rack meshing movement of the upper part of the square frame 82, so that the T-shaped sliding plate 83 moves smoothly inside the chute, driving the abutting head 86 forward, so that the abutting head 86 abuts against the second switch 88, thereby cutting off the power supply of the stamping machine 3. After disconnection, the half gear 84 rotates to the rack at the lower part of the square frame 82 to drive the square frame 82 to return to the initial position and then stop the rotation of the second motor 85, thus realizing the detection and power-off of adhesion. Embodiment Two

[0045] Refer to Figure 7 - Figure 12 , the difference from Embodiment One is that: A horizontal box 15 is fixedly arranged between the base 1 and the bottom plate 2.

The number of the first electric push rods 101 is two and they are fixedly arranged inside the groove, and the output end of the first electric push rod 101 is fixedly arranged with the supporting plate 102.

[0048] Refer to Figure 9 - Figure 12 , the detection mechanism 11 includes an inverted L-shaped plate 111, a second electric push rod 112, a first clamping plate 113, a third electric push rod 114, a second clamping plate 115, and a first electric telescopic rod 116. The number of the inverted L-shaped plates 111 is two and they are located on both sides of the stamping seat 5. One side of the outer wall of the inverted L-shaped plate 111 is fixedly arranged with the output end of the first electric telescopic rod 116. The number of both the second electric push rod 112 and the third electric push rod 114 is multiple, and they are respectively located on both sides of the inner wall of the inverted L-shaped plate 111. The output end of the second electric push rod 112 is fixedly arranged with the first clamping plate 113, and the output end of the third electric push rod 114 is fixedly arranged with the second clamping plate 115.

[0049] The moving component 12 includes a third motor 121, a second lead screw 122, a moving I-shaped plate 123, a moving plate 124, a first air cylinder 125, an abutting plate 126, a second electric telescopic rod 127, and a touch plate 128. The third motor 121 is fixedly arranged on one side wall of the horizontal box 15. The second lead screw 122 is rotatably arranged on both sides of the inner wall of the horizontal box 15 through bearings. The moving plate 124 is threadedly connected to the second lead screw 122. The top of the moving plate 124 is fixedly arranged with the moving I-shaped plate 123. A chute for the moving I-shaped plate 123 to slide is opened on the bottom plate 2. The bottom of the first electric telescopic rod 116 is fixedly arranged with the moving I-shaped plate 123. The bottom of the moving plate 124 is fixedly arranged with the first air cylinder 125, and the output end of the first air cylinder 125 is fixedly arranged with the abutting plate 126. The bottom of the abutting plate 126 is rotatably arranged with the touch plate 128 through a rotating shaft. The second electric telescopic rod 127 is fixedly arranged on one side of the outer wall of the abutting plate 126, and the output end of the second electric telescopic rod 127 is fixedly arranged with one side of the outer wall of the touch plate 128.

[0050] There are two sets of judgment mechanisms 13 which are symmetrically arranged. Each set has a plurality of judgment mechanisms 13 which are evenly and fixedly arranged inside the horizontal box 15. The judgment mechanism 13 includes a movable rotating plate 131 and a transmission switch 132. One end of the movable rotating plate 131 is rotatably arranged on the inner bottom wall of the horizontal box 15 through a rotating shaft, and a spring is fixedly arranged between the bottom of the movable rotation and the inner wall of the horizontal box 15. The transmission switch 132 is fixedly arranged on the bottom wall of the horizontal box 15 and is located directly below the movable rotating plate 131.

[0051] In this embodiment: When the stamping machine 3 is stamping normally and no adhesion occurs, after the plastic sheet is stamped and formed, a part of the formed sheet has a low firmness due to excessive heating, so it is necessary to detect the firmness of the plastic sheet and eliminate unqualified formed products. After stamping, the first motor 64 is started to drive the first lead screw 62 to rotate, so that the stamping seat 5 drives the stamped plastic sheet to move to the position for detection and then stops. Since the plastic sheet is in close contact with the stamping seat 5 during stamping and its hardness is low due to high temperature, it is further difficult to easily clamp the plastic sheet for detection during the detection process. By setting the induction component 9, when the stamping seat 5 is about to move to the detection position, one side wall of the stamping seat 5 abuts against the surface of the triangular block 93. As the stamping seat 5 moves, it pushes the triangular block 93 to move inside the chute, so that the triangular block 93 moves to touch the third switch 92 and then stops moving. The third switch 92 provides a signal to the supporting component 10, and the first electric push rod 101 is started to drive the supporting plate 102 to rise, so that the supporting plate 102 lifts the stamped sheet, making both ends of the sheet empty, which is convenient for later detection;

[0052] Start the detection mechanism 11 for detection. Start the first electric telescopic rod 116 to drive the inverted L-shaped plate 111 to adjust the clamping height. After the adjustment is completed, start the second electric push rod 112 to drive the first clamping plate 113 to insert into the bottom of the vacated sheet. Subsequently, start the third electric push rod 114 to drive the second clamping plate 115 to press down on the top of the sheet, so that the two clamping plates clamp the sheet. After the clamping is completed, start the first cylinder 125 to drive the abutting plate 126 to descend, and stop when the touch plate 128 can trigger the judgment mechanism 13. Start the second electric telescopic rod 127 to drive the touch plate 128 to rotate. The rotation of the touch plate 128 drives the movable rotating plate 131 to rotate, so that the movable rotating plate 131 presses the transmission switch 132 to trigger it. Start the third motor 121 again to drive the second lead screw 122 to move, so that the moving plate 124 and the moving I-shaped plate 123 slide inside the chute. When the hardness of the sheet is qualified, the sheet cannot be pulled, and the switch in the nearest set of judgment mechanisms 13 to the sheet will continue to be triggered. The switch trigger time can be set, and it is qualified within 3 s of the trigger time. When the hardness of the sheet is unqualified, the sheet will be pulled, and during the movement of the touch plate 128, it will abut the transmission switches 132 at the bottoms of the other two sets of movable rotating plates 131. Different switches have different functions, and different switches indicate the qualification of the product. Embodiment 3
