Description

Technical Field

[0001] The invention relates to the technical field of polytetrafluoroethylene plate stamping, in particular to a stamping forming machine for processing polytetrafluoroethylene plates which is convenient for material cutting. Background Art

[0002] Polytetrafluoroethylene (PTFE) is a polymer made from tetrafluoroethylene. It is a white, odorless, tasteless, non-toxic powder with a density of about 2.1-2.3 g / cm 3 It is solid and flexible at room temperature. It has excellent thermal properties and can be used for a long time at -180℃-260℃. For example, it can withstand high temperatures in high-temperature cooking utensils coatings. Polytetrafluoroethylene has a low friction coefficient and is self-lubricating. It is used to manufacture bearings, piston rings, etc. in mechanical manufacturing to reduce wear. It has extremely high chemical stability and is almost not corroded by chemical reagents except molten alkali metals. It is used in the chemical industry to manufacture corrosion-resistant pipes, containers, valves, etc. For example, polytetrafluoroethylene pipes in sulfuric acid production workshops can safely transport sulfuric acid; it has strong weather resistance and can resist ultraviolet rays, ozone, etc., and can be used for outdoor building materials, antenna covers, etc. Polytetrafluoroethylene sheets are sheets made of polytetrafluoroethylene resin by molding, turning and other processes;

[0003] In the prior art, since polytetrafluoroethylene has a relatively low surface energy, the workpiece after stamping is easily adhered to the polytetrafluoroethylene plate. When the staff manually removes it, a large external force is required, and it is difficult to ensure that the demoulding force acts evenly on the workpiece. The uneven force will cause the wall of the workpiece to bend, affecting the dimensional accuracy and performance of the workpiece. In addition, since there is no special storage structure inside the cart after the polytetrafluoroethylene is stamped, the workpiece can only be stacked on the cart at will, resulting in the workpieces after the polytetrafluoroethylene plate is stamped to collide with each other on the cart, causing scratches or slight deformation on the surface of the workpiece.

The first motor 29 drives the internal lead screw of the lead screw assembly 28 to rotate under the transmission of the transmission belt assembly 210, so that the internal lead screw nut of the lead screw assembly 28 drives the first mounting plate 211. The first mounting plate 211 moves forward and backward under the limiting action of the limiting guide rail assembly 27, so that the upper lifting seat 217 is aligned with the processing position of the polytetrafluoroethylene plate. The first electric telescopic rod 212 is extended to drive the second mounting plate 213 to move upward to a specified height position, so that the upper surface of the support plate 215 is in contact with the lower surface of the polytetrafluoroethylene plate. The second electric telescopic rod 218 is extended to drive the lifting seat 217 to move upward in the inner cavity of the insert cylinder 216 to eject the molded workpiece inside the polytetrafluoroethylene plate, so that it falls off from the inside of the polytetrafluoroethylene plate and falls into the housing 21.

[0034] Step 2: The workpiece moving robot 6 moves the polytetrafluoroethylene plate back to the inside of the plate punching machine 1 for further processing until the inside of the polytetrafluoroethylene plate is completely stamped and formed. The material moving component 3 drives the workpiece moving robot 6 to move to the rear of the right electric conveyor belt 7. The workpiece moving robot 6 places the remaining polytetrafluoroethylene plate on the surface of the right electric conveyor belt 7. The right electric conveyor belt 7 moves the remaining polytetrafluoroethylene plate to the inside of the external waste collection equipment for processing. The prefabricated program inside the main controller 4 remotely controls the sub-controller 34 to start. The prefabricated program inside the sub-controller 34 controls the slot seat 36, the electric suction cup 314, the fourth electric telescopic rod 312 and the second motor 322 to start. The slot seat 36 extends to drive the moving frame 38 to move to the left on the inside of the slot seat 36, so that the moving frame 38 drives the bottom frame 39 to pass through the inner cavity of the slot body 35 and move to the outside. The prefabricated program inside the main controller 4 controls the three-axis handling module 23 to start. The three-axis handling module 23 moves the formed workpiece to the top of the top frame 313. The electric suction cup 314 is used to control the forming workpiece. The workpiece is adsorbed and fixed, the slot seat 36 is shortened to move the workpiece to the inner cavity of the van trolley 31, the fourth electric telescopic rod 312 is extended to drive the top frame 313 to move upward to the inside of the mounting rod 315, and the second motor 322 drives the second rotating shaft 320 to rotate under the transmission of the transmission gear set 323, so that the second rotating shaft 320 drives the first rotating shafts 316 at the bottom on the left and right sides to rotate synchronously in the opposite direction under the transmission of the bevel gear sets 321 on both sides, and the first rotating shaft 316 at the bottom drives the sprockets 317 on the front and rear sides to rotate, so that the chains 317 on both sides are connected. 18 rotates circumferentially under the action of the rotational force of the bottom sprocket 317 and the limiting action of the top sprocket 317, and the chains 318 on the left and right sides drive several brackets 319 to move circumferentially in the counterclockwise direction, so that the brackets 319 on the left and right sides lift the workpieces on the surface of the electric suction cup 314 upward to a specified height position for storage. After a sufficient number of formed workpieces are stored in the box trolley 31, the staff moves the box trolley 31 out of the inner side of the shell 21 and replaces the empty material moving component 3 to realize the cyclic operation.
