Description
Technical Field
The application belongs to the technical field of tool clamps, and particularly relates to a clamp structure for spray welding of a die cavity of a glass die.
Background
As is known in the art, glass molds are important equipment for manufacturing glass containers, and the aforementioned port molds are important components for controlling the molding of the mouth portions of glass containers in glass mold assemblies, and since the inner cavity of the port mold (commonly referred to as the port mold cavity) is matched with the port ring, the sleeve, the punch and the like, and the outer portion, i.e., the side facing away from the inner cavity, is matched with the primary mold, the mating surface of the port mold is the most well-known among all the components of the glass mold set, and the precision requirement is high. Meanwhile, in the use process, the heat of the die is concentrated, the abrasion is large, and particularly the inner cavity of the die is more easily worn, so that a hard alloy material layer such as nickel-based alloy welding powder is usually sprayed and welded in the inner cavity of the die, and the hard alloy material layer is used as a wear-resistant body to enhance the wear resistance of the inner cavity of the die, so that the service life of the die is prolonged.
Furthermore, as known in the art, it is necessary to fix the glass mold body and the die to the corresponding jigs in advance, and then spray-weld the die cavity by an automatic spray-welding device, both of the cavity of the glass mold body and the die cavity are spray-welded with a cemented carbide material layer (also referred to as "wear-resistant alloy material layer").
Technical information for clamping glass molds such as CN101659015B (tool jig for machining glass molds), CN101891373B (tool jig for machining glass molds), CN101891372B (tool jig for machining glass molds), CN101898311B (tool jig for milling positioning reference surface on glass mold blanks), CN102380777B (tool jig for machining glass molds), CN102443859B (tool jig for machining glass molds), CN102350650B (tool jig for machining glass molds), CN102350651B (tool jig for machining glass molds with improved structure), CN102689187a (tool jig for turntable for machining glass molds), CN102848039a (tool jig for machining glass mold punch cooling grooves arranged on electric spark machine), CN102837213A (tool jig for machining glass molds), CN102848246A (tool jig for machining glass molds), CN102848245A (tool jig for machining glass molds), CN103056695A (tool jig for machining inner cavity and joint surface), CN103084771a (tool jig for welding), and the like are widely known in the published chinese patent literature.
Technical information about clamping a glass die is also seen in the published chinese patent literature, such as CN104175153B (jig structure for processing a glass die), CN104162800B (jig for processing a glass die), CN205074839a (jig for processing a glass die), CN201736059U (die jig), and the like. Because the die clamps are all proposed for clamping during the metal processing of the die, the clamping during the spray welding of the die cavity of the die has no technical teaching for reference.
As can be seen from a reading of the patent literature, which is not limited to the above: the fixture has the special characteristics of aiming at the processing technology of a certain product or the processing technology of a certain product, thus belonging to non-standard devices (the non-standard devices are not in international and domestic standards or even industry standard specifications), and the non-standard devices have no technical universality and no technical borrowability, and are usually customized (including self-design and self-manufacture) by manufacturers producing products or using specific processes to produce products in a mode of tailoring and seating. Based on this situation, in particular, technical information of a tool fixture which is helpful for a laser automatic spray welding machine to spray weld a nickel-based alloy layer, namely the hard alloy material layer, to a die cavity in a reliable clamping state of a glass die is not found in the middle and outer patent and non-patent documents disclosed previously, so that a clamping mode of die metal processing is widely used, and specifically: the die to be spray welded is placed on a bracket with a V-shaped groove in cross section in a state that a die cavity is upwards, a pressing plate is placed on two sides of the die cavity opening of the die in the length direction, and the two pressing plates are fixed with the bracket by bolts at positions corresponding to bolt holes on the bracket. The clamping mode has at least the following disadvantages: firstly, the clamping efficiency is affected due to troublesome clamping, and finally the spray welding efficiency is improved; secondly, after the die is clamped at the V-shaped groove part on the bracket, the die is difficult to ensure to be in a desired horizontal state, however, whether the die is clamped horizontally or not can influence the consistency of the thickness of the nickel-based alloy layer sprayed and welded in the die cavity of the die and finally influence the service life of the die; thirdly, in order to ensure that the die is in a horizontal state on the clamp as far as possible, the clamping workers also need to observe by means of a level meter, so that the clamping operation strength of the clamping workers is enhanced, and the clamping efficiency is greatly influenced.
In view of the above prior art, the present inventors have made beneficial designs, which form the technical solutions described below and have made simulation tests in the test center of the present inventors with reasonable security measures, and as a result have proved to be practical.
