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: 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.

[0004] 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.

[0005] 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.

[0017] The present invention has the following beneficial effects: 1. This device is equipped with a detection component and a power-off component. When the punching machine punches the plastic sheet, the mold temperature has a significant impact on the adhesion of the plastic sheet during the punching process. When the mold temperature is too high, the plastic sheet may adhere to the mold, resulting in mold sticking. If the mold surface temperature is too high, the alloy material will easily adhere to the mold, resulting in mold sticking. The punching machine and the punching seat will stick together due to the plastic sticking problem. At this time, the detection component can be used to detect whether an unexpected adhesion occurs, and the power-off component can be used to cut off the power of the punching machine to ensure that emergency response can be made in the event of an unexpected situation. 2. This device is equipped with a detection mechanism, a moving component and a judgment mechanism to form a large detection mode. When the punching machine is punching normally and no adhesion occurs, a part of the formed sheet will be less firm due to being heated for too long after the plastic sheet is punched. The firmness of the plastic sheet is tested through the detection mode to eliminate unqualified formed products. 3. By setting up the sensing component and the supporting component, since the plastic sheet is closely attached to the stamping seat during stamping, and the hardness is low due to the high temperature, it is further impossible to easily clamp the plastic sheet for inspection during the inspection process. By setting up the sensing component, when the stamping seat is about to move to the inspection position, the sheet to be inspected is vacated by the supporting component, which is convenient for later inspection; 4. By setting up a classification mechanism, qualified products and waste products can be screened. Some sheets may be stamped simultaneously with other materials during the stamping process. After passing the inspection, the degree of adhesion between the adhesives can be preliminarily screened during the classification process. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Reference Figure 4 The detection component 7 includes a positioning side plate 71, a cross bar 72, a rotating protrusion 73 and a first switch 74. There are two positioning side plates 71 and both are fixed to the bottom plate 2. The cross bar 72 is fixed between the two positioning side plates 71, and the cross bar 72 passes through the rotating protrusion 73 and is provided with a bearing at the connection with the rotating protrusion 73. A reset spring is fixed between the rotating protrusion 73 and the positioning. The first switch 74 is fixed to the bottom plate 2 and is located directly below the rotating protrusion 73.

[0025] Reference Figure 5-Figure 6 The power-off component 8 includes a positioning frame 81, a square frame 82, a T-shaped slide 83, a half-side gear 84, a second motor 85, a contact head 86, a vertical plate 87 and a second switch 88. The positioning frame 81 is fixed to the base 1, the top of the square frame 82 is fixed to the T-shaped slide 83, and a slide groove for the T-shaped slide 83 to slide is opened inside the positioning frame 81. Racks are fixed on both the upper and lower sides of the inner wall of the square frame 82. The half-side gear 84 is rotatably arranged with the inner wall of the positioning frame 81 through a bearing, and the half-side gear 84 extends between the upper and lower sides of the inner wall of the square frame 82 and is meshed with the rack. The second motor 85 is fixed to one side of the outer wall of the positioning frame 81 and the output end is fixed to the half-side gear 84. The contact head 86 is fixed to one side of the outer wall of the square frame 82, the vertical plate 87 is fixed to the base 1, and the second switch 88 is fixed to the vertical plate 87, and the second switch 88 and the contact head 86 are located on the same horizontal line.

[0026] In this embodiment: the initial position of the punching seat 5 is located at the top of the support seat 4, and the plastic sheet can be placed on the top of the punching seat 5. When the punching machine 3 is started to punch the plastic sheet, the mold temperature has a significant effect on the adhesion of the plastic sheet during the punching process. When the mold temperature is too high, the plastic sheet may adhere to the mold, resulting in mold sticking. The mold surface temperature is too high, which will cause the alloy material to easily adhere to the mold, thereby causing a mold sticking problem. The punching machine 3 and the punching seat 5 are stuck to each other due to the plastic sticking problem. At this time, the detection component 7 can be used to detect whether an unexpected adhesion occurs. Under normal circumstances, when the punch head descends, it will abut against the rotating The surface of the protrusion 73 provides pressure to drive the rotating protrusion 73 to rotate 90 degrees and touch the first switch 74 during continuous downward pressure. When the punch head is not normally adhered, it will be separated from the first switch 74 within a certain period of time (the time can be set according to the different punching machines 3). Assuming that the normal situation is two seconds, when adhesion occurs, the punch head and the punching seat 5 are adhered and cannot be easily separated. At this moment, the rotating protrusion 73 will continue to abut or 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), the power-off component 8 is activated to disconnect the power supply to check the situation at the 3rd second to avoid accidents. 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 at the upper part of the square frame 82 to engage and move, so that the T-shaped slide 83 moves smoothly inside the slide groove, driving the contact head 86 forward, so that the contact head 86 abuts against the second switch 88, thereby disconnecting the power supply of the punching 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 its initial position and then stop the rotation of the second motor 85, thereby realizing adhesion detection and power off.

The transmission switch 132 is fixed to the bottom wall of the transverse box 15 and is located directly below the movable rotating plate 131.

[0033] In this embodiment: when the punching machine 3 is punching normally and no adhesion occurs, after the plastic sheet is punched and formed, a part of the formed sheet will be less firm due to being heated for too long, so it is necessary to test the firmness of the plastic sheet and eliminate unqualified formed products. After the punching is completed, the first motor 64 is started to drive the first screw 62 to rotate, so that the punching seat 5 drives the punched plastic sheet to move to the testing position and then stops. Since the plastic sheet is tightly fitted with the punching seat 5 during punching, and the hardness is lower due to the high temperature, it further leads to During the detection process, it is not easy to clamp the plastic sheet for detection. By setting the sensing component 9, when the punching seat 5 is about to move to the detection position, the side wall of the punching seat 5 abuts against the surface of the triangular block 93. As the punching seat 5 moves, the triangular block 93 is pushed to move inside the slide slot, so that the triangular block 93 moves and touches the third switch 92 and then stops moving.

The movable rotating plate 131 squeezes the transmission switch 132 to trigger it, and the third motor 121 is started again to drive the second screw rod 122 to move, so that the movable plate 124 and the movable I-shaped plate 123 slide inside the slide groove. When the hardness of the sheet is qualified, the sheet cannot be pulled, and the switches in a group of judgment mechanisms 13 closest to the sheet will be continuously triggered. The switch trigger time can be set, and it is qualified within 3s 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 against the transmission switches 132 at the bottom of the other two groups of movable rotating plates 131.
