The wheel guard 3102 is square, and is horizontally fixed at the front end of the telescopic rod, and can extend between the silver stamping surface die 306 and the silver stamping bottom die 3080. When the feeding booster 206 is used to drive the wheel blanks to quickly enter the silver ironing groove 3081 of the silver ironing bottom die assembly 308 by spraying high-pressure gas, the wheel guard cylinder 3100 drives the wheel guard plate 3102 to extend between the silver ironing surface die 306 and the silver ironing bottom die 3080, so that the wheel blanks in the silver ironing groove 3081 are completely covered, and the wheel blanks are prevented from being blown off by the high-pressure gas.

The first choke assembly 312 includes a first choke cylinder 3120 and a first choke member 3122, the first choke cylinder 3120 being secured to the top of the frame 10 and upstream of the silver stamping die assembly 308. The first choke cylinder 3120 has a telescoping rod that faces vertically upward. The first material blocking member 3122 includes a connecting rod horizontally fixed at the front end of the telescopic rod of the first material blocking cylinder 3120 and 4 first material blocking rods fixed at the first connecting rod, the first material blocking rods are vertically upward, and each first material blocking rod corresponds to a silver ironing groove 3081. When the first resistance cylinder 3120 drives the first resistance member 3122 vertically upward, the first resistance member 3122 restricts the flow of wheel blanks within the feed tank 200 into the silver-ironing tank 3081.

The second blocking assembly 314 includes a second blocking cylinder 3140 and a second blocking member 3142, the second blocking cylinder 3140 being fixed to the top of the frame 10 and downstream of the silver stamping die assembly 308. The second blocking cylinder 3140 has a telescoping rod that faces vertically upward. The second material blocking member 3142 comprises a connecting rod horizontally fixed at the front end of the telescopic rod of the second material blocking cylinder 3140 and 4 second material blocking rods fixed on the second connecting rod, the second material blocking rods are vertically upwards, and each second material blocking rod corresponds to one silver ironing groove 3081. When the second resistance cylinder 3140 drives the second resistance member 3142 to vertically move upward, the second resistance member 3142 restricts the wheel blank flow silver groove 3081 in the silver groove 3081.

Because the wheel blank is still in the in-process of removal when getting into the silver stamping groove 3081, when silver stamping briquetting 3060 presses silver stamping paper towards the wheel blank, the inaccurate counterpoint appears easily. To solve this problem, the silver ironing die assembly 308 of the silver ironing apparatus for model vehicle wheels includes a silver ironing die 3080 and a die transposition base 3082. Specifically, as shown in fig. 8, the silver stamping bottom die 3080 is specifically square, and a plurality of first silver stamping concave positions 3080a arrayed along the first direction D1 and the second direction D2 are arranged at the top of the silver stamping bottom die, and two opposite sides of the first silver stamping concave positions 3080a along the first direction D1 are open structures. A first sliding groove 3080b parallel to the second direction D2 is disposed between two adjacent first silver stamping concave positions 3080a along the first direction D1, so that two sides of each first sliding groove 3080b form a first protruding portion 3080c with a plurality of first silver stamping concave positions 3080a linearly arranged. The bottom die transposition base 3082 is specifically square, the top of the bottom die transposition base is provided with second silver stamping concave positions 3082a which are arrayed along the first direction D1 and the second direction D2, and two opposite sides of the second silver stamping concave positions 3082a along the first direction D1 are of opening structures. A second sliding groove 3082b parallel to the second direction D2 is disposed between two adjacent second silver stamping concave positions 3082a along the second direction D2, so that two sides of each second sliding groove 3082b form a second protruding portion 3082c with a plurality of second silver stamping concave positions 3082a arranged linearly. Wherein the second sliding groove 3082b is a through groove; each second sliding groove 3082b corresponds to a first protruding portion 3080c, and the width of the second sliding groove 3082b is slightly larger than the width of the first protruding portion 3080c, and the length thereof is larger than the length of the first protruding portion 3080c along the second direction D2. The bottom mold transposition base 3082 is combined on the silver stamping bottom mold 3080, each second sliding groove 3082b corresponds to a first protruding portion 3080c, and the first protruding portion 3080c penetrates through the second sliding groove 3082b and can slide in the second sliding groove 3082 b.

As shown in fig. 9, when the silver-ironing bottom die 3080 moves along the second sliding groove, such that the first silver-ironing recess 3080a on the first protruding portion 3080c slides to align with the second silver-ironing recess 3082a on the second protruding portion 3082c, a silver-ironing groove 3081 is formed, and the wheel base can move within the silver-ironing groove 3081. As shown in fig. 10, when the wheel blanks in the silver plating groove 3081 enter the first silver plating concave position 3080a and the second silver plating concave position 3082a, the silver plating bottom die 3080 is driven to move along the second direction D2, so that the first silver plating concave position 3080a and the second silver plating concave position 3082a are dislocated, the silver plating bottom die 3080 and the bottom die transposition base 3082 which are overlapped together form a lattice surface, and the first silver plating concave position 3080a and the second silver plating concave position 3082a are distributed in an array. At this time, since the wheel blanks located in the first silver-plating concave portion 3080a are blocked by the second protruding block 3082c on both sides in the first direction D1, the wheel blanks are restricted in the first silver-plating concave portion 3080a and do not move forward any more. Similarly, since the wheel blanks located in the second silver plating concave portion 3082a are blocked by the first protruding block 3080c on both sides in the first direction D1, the wheel blanks are also restricted in the second silver plating concave portion 3082 a. At this time, the silver stamping press 3060 is opposite to the wheel blank in the first silver stamping concave 3080a, so when the die assembly 302 drives the silver stamping face die 306 to move downwards, the silver stamping press 3060 presses the silver stamping paper to the wheel blank in the first silver stamping concave 3080a, and the silver stamping process is completed. Then, the silver-ironing bottom die 3080 is reset, so that the first silver-ironing concave position 3080a is aligned with the second silver-ironing concave position 3082a again, the wheel blank originally positioned in the second silver-ironing concave position 3082a enters the adjacent first silver-ironing concave position 3080a, at this time, the silver-ironing bottom die 3080 moves along the second sliding groove 3082b again, the first silver-ironing concave position 3080a and the second silver-ironing concave position 3082a are dislocated again, and the pressing block presses the silver-ironing paper to the wheel blank positioned in the first silver-ironing concave position 3080a again, so that silver ironing is completed, and the cycle is completed.

Further, the silver plating bottom die assembly 308 further includes a transposition cylinder 3084 and a transposition connecting plate 3086 disposed on one side of the silver plating bottom die 3080. The index cylinder 3084 has an index telescopic rod facing the silver-ironing bottom die 3080 and parallel to the second direction D2. Here, the transposition telescopic rod may be directly fixed to the silver stamping bottom die 3080, or may be fixedly connected to the silver stamping bottom die 3080 through a transposition connecting plate 3086 as shown in fig. 9 and 10, so as to drive the silver stamping bottom die 3080 to move along the second sliding groove 3082 b.

When the silver stamping mechanism 30 works, the guard wheel assembly 310, the first material blocking assembly 312 and the first material blocking assembly 314 cooperate, before a wheel blank enters the silver stamping groove 3081, the first material blocking cylinder 3120 drives the first material blocking member 3122 to move upwards along the third direction D3, meanwhile, the guard wheel cylinder 3100 drives the guard wheel plate 3102 to extend into the upper part of the silver stamping groove 3081, and the second material blocking cylinder 3140 simultaneously drives the second material blocking member 3142 to move upwards along the third direction D3, so that the wheel blank is limited to flow out of the silver stamping groove 3081. Then, the feeding booster 206 sprays high-pressure gas to drive the wheel blank in the feeding groove 200 to flow into the silver plating groove 3081, and after the wheel blank fills the silver plating groove 3081, the first material blocking cylinder 3120 drives the first material blocking member 3122 to move upwards along the third direction D3 so as to limit the wheel blank to flow into the silver plating groove 3081 again. Then, the transposition cylinder 3084 drives the silver stamping bottom die 3080 to move along the second direction D2 to form a lattice surface, so that the wheel blank positioned at the first silver stamping concave position 3080a is opposite to the pressing die convex block 3060. At this time, the wheel guard cylinder 3100 and the second blocking cylinder 3140 respectively drive the wheel guard 3102 and the second blocking member 3142 to reset at the same time, and the die assembly 302 drives the silver stamping face die 306 to press the silver stamping paper to the wheel blank, thereby finishing silver stamping. After finishing the silver stamping, the first moving cylinder 800 drives the cleaning rod 804 to move along the first direction D1, sweeps off the wheel finished product adhered on the silver stamping paper to the feed opening 10a, and then discharges from the feed chute 60. After the wheel blank is completely swept, the first material blocking cylinder 3120 drives the first material blocking piece 3122 and the second material blocking piece 3142 to reset, and at the same time, the transposition cylinder 3084 drives the silver ironing bottom die 3080 to reset, so that the silver ironing groove 3081 is formed again. The wheel base flows into the silver plating tank 3081 again and moves in the silver plating tank 3081, and then starts the next silver plating process.

Further, the silver plating apparatus for model vehicle wheels further includes two wheel screening mechanisms 90 disposed upstream of the wheel feeding mechanism 20. The wheel screening mechanism 90 includes a hopper tank 900 and a screening vibration generator 902, the hopper tank 900 being located upstream of the feed tank 200 for holding wheel blanks to be silver-stamped. The inner side wall of the funnel groove 900 is provided with a spiral wheel channel, and the top of the funnel groove 900 is provided with a notch which is communicated with the two channels 200a of the feed groove 200. The screening vibration generator 902 is disposed at the bottom of the hopper tank 900, and is used for driving the wheel blank in the hopper tank 900 to move to the top of the hopper tank 900 along the wheel channel through vibration, and enter the channel 200a of the feed tank 200 through a notch at the top of the hopper tank 900.

In practical application, the wheel channel (not shown) is set to be in a special shape, so that the wheel blank with the outer side always facing upwards is screened out and driven into the feed tank 200, and the subsequent silver stamping process is facilitated. Since the screening method belongs to the prior art, the screening method can be adjusted according to actual needs, and therefore, the screening method is not described in detail herein.
