Description

Technical Field

[0001] The utility model relates to the technical field of presses, in particular to an anti-pinch press for preparing sandwich composite panels. Background Art

[0002] Sandwich panel products are composed of two layers of formed metal panels and a polymer insulation core that is foamed and cured directly between the panels. These finished sandwich panels are easy to install, lightweight and highly efficient. Sandwich panels are used in large industrial plants, warehouses, gymnasiums, supermarkets, hospitals, cold storages, mobile homes, building mezzanines, clean workshops and places that require thermal insulation and fire protection. The sandwich panel has beautiful appearance, bright color and good overall effect. It integrates load-bearing, heat preservation, fire prevention and waterproofing, and does not require secondary decoration. The sandwich composite panel needs to be pressed with a press during the processing. After searching, the Chinese patent with publication number CN211942470U discloses a sandwich composite panel production press with anti-pinching function. It drives a lifting plate that can be lifted and lowered. When squeezing, the lifting plate is separated from the contact with the lower clamping plate. At the same time, the lifting plate will continue to move up and contact the upper clamping plate to complete the squeezing. In this way, the upper clamping plate will not contact the lower clamping plate. However, it has usage limitations. If the operator's hand is placed on the composite board, it can move up with the lifting plate. The operator is easily pinched by the lifting plate and the upper clamping plate inadvertently.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-6 A sandwich composite panel preparation anti-pinch press comprises a frame 1, a pressure-driven cylinder 2 is arranged on the top of the frame 1, an upper pressing plate 3 is fixedly installed on the bottom of the pressure-driven cylinder 2, a lower pressing plate 4 fixedly installed on the frame 1 is arranged below the upper pressing plate 3, a circle of outer concave ring groove 5 is arranged around the bottom of the upper pressing plate 3, a guide slide frame 6 with a body temperature sensor 7 installed on the bottom is slidably matched at the outer concave ring groove 5, an elastic mechanism is arranged between the top of the guide slide frame 6 and the upper pressing plate 3, a controller 11 is installed on the frame 1, the pressure-driven cylinder 2 and the body temperature sensor 7 are electrically connected to the controller 11, and further, the body temperature sensor 7 can be set to be multiple and arranged at the bottom of the guide slide frame 6 in a ring-shaped interval.

[0024] Specifically, the elastic mechanism is set to four groups and is arranged at the four corners of the upper pressure plate 3. The elastic mechanism includes a slide bar 8 that is guided and slidably matched with the upper pressure plate 3. The bottom end of the slide bar 8 is fixedly connected to the guide slide frame 6. The top end of the slide bar 8 is fixedly installed with a limit plate 9. A spring 10 is mounted on the slide bar 8. The top and bottom ends of the spring 10 are respectively fixedly connected to the limit plate 9 and the upper pressure plate 3. When the temperature sensor 7 moves downward with the upper pressure plate 3, the temperature sensor 7 first contacts the object. After it contacts the object, the temperature sensor 7 and the guide slide frame 6 can be integrally embedded in the outer concave ring groove 5 through the cooperation of the slide bar 8, the limit plate 9 and the spring 10. When in contact, under the action of the rebound force of the spring 10, the guide slide frame 6 and the temperature sensor 7 slide down along the outer concave ring groove 5 as a whole so that the bottom of the temperature sensor 7 is lower than the height of the bottom end surface of the upper pressure plate 3.

[0025] Specifically, a liftable embedded support plate 13 is embedded in the lower pressure plate 4, and an embedded groove 12 matched with the embedded support plate 13 is opened on the inner top of the lower pressure plate 4. A lifting drive cylinder 14 is fixedly installed on the bottom of the lower pressure plate 4, and the top output end is fixedly connected to the bottom of the embedded support plate 13. When the lifting drive cylinder 14 is started, the embedded support plate 13 embedded in the embedded groove 12 can be lifted up, so that the sandwich composite panel placed thereon is separated from the contact with the lower pressure plate 4, further reducing the possibility of being clamped.

[0026] Specifically, it also includes a horizontal moving mechanism, which includes a horizontal slide 16 that slides horizontally on the top of the frame 1, and the pressure drive cylinder 2 is fixedly installed on the horizontal slide 16. A moving drive component is arranged on the horizontal slide 16, and the upper pressure plate 3 is fixedly connected to the output end of the pressure drive cylinder 2 by bolts. The upper pressure plate 3 is fixedly connected to the output end of the pressure drive cylinder 2 by bolts, so that the upper pressure plate 3 can be easily replaced, so that it is convenient to replace upper pressure plates 3 of different specifications according to the size of the sandwich composite panel. Through the moving drive component, it is convenient to drive the horizontal slide 16 and the pressure drive cylinder 2 to move left and right as a whole, so that the position can be found according to the left and right position of the sandwich composite panel placed on the lower pressure plate 4.

[0027] Specifically, the mobile drive assembly includes a rotating shaft rotatably connected to the horizontal slide 16, and a gear 17 and an adjusting dial 18 are fixedly installed at both ends of the rotating shaft. A rack 15 meshing with the gear 17 is horizontally fixedly connected to the frame 1. By rotating the adjusting dial 18, the gear 17 is driven to rotate, so that the gear 17 is meshed with the rack 15, and the gear 17 is driven to move left and right on the rack 15, thereby driving the horizontal slide 16 and the pressure drive cylinder 2 to move left and right as a whole.

[0028] When in use, the sandwich composite panel to be extruded is placed on the lower pressing plate 4, and then the pressure driving cylinder 2 is started through the controller 11 to drive the upper pressing plate 3 to move downward. When moving downward, the body temperature sensor 7 first contacts the sandwich composite panel. If the operator's hand is placed on the sandwich composite panel, the body temperature sensor 7 senses the body temperature and then transmits the signal to the controller 11. The controller 11 controls the pressure driving cylinder 2 to stop, thereby preventing the upper pressing plate 3 from moving further downward, so that the extrusion can be stopped, the hand can be pulled out, and the extrusion operation can be continued.
