[0002] When manufacturing circular cover products, in order to improve the utilization rate of stamping equipment, the prior art integrates multiple stamping stations and two groups of rolling stations on one stamping equipment for operation. The specific operation process is as follows Figure 1 , product blank 1 → product 2 after outer coiling line processing → product 3 after rib rolling line processing → product 4 after thread rolling processing → product 5 after punching and flanging processing → product 6 after inner coiling line processing. Among them, rib rolling line processing and thread rolling processing are rolling operations. In the prior art, rib rolling line processing and thread rolling processing are respectively set with independent motors for driving operations. In actual operation, the cost is relatively high, and due to the long-term operation of the rolling work, the transmission belt will become loose, which will cause defects in the rolled products. Therefore, it is urgent to develop a rolling working mechanism to ensure the tension state of the transmission belt and at the same time reduce the manufacturing cost of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] A rolling working mechanism of a multi-station stamping device, see Figures 2 - 7, which includes a stamping lifting plate 10, a bottom plate 20, a roll pressing working upper plate 30, a roll pressing drive motor 40, a first roll pressing die 50, and a second roll pressing die 60.

[0029] The stamping lifting plate 10 is connected to the upper punch. A number of processing stations with equal intervals are sequentially arranged on the bottom plate 20, specifically an outer coil line processing station 201, a bead rolling line processing station 202, a thread rolling processing station 203, a punching and flanging processing station 204, and an inner coil line processing station 205. Among them, a lifting mechanism 70 is arranged at the bottom of the bead rolling line processing station 202 and the thread rolling processing station 203. The lifting mechanism 70 is used to lift the cover body during roll pressing.

[0030] The first roll pressing die 50 corresponds to a bead rolling roll pressing die; the second roll pressing die 60 corresponds to a thread rolling roll pressing die.

[0031] An avoidance notch 11 is arranged at the position of the stamping lifting plate 10 corresponding to the roll pressing working upper plate. A part of the roll pressing working upper plate 30 is arranged in the avoidance notch 11. A side convex auxiliary support plate 21 is arranged on one side of the bottom plate 20.

[0032] The roll pressing working upper plate 30 is supported on the upper surface of the side convex auxiliary support plate 21 through a vertical frame 80. The bottom of the roll pressing drive motor 40 is fixedly arranged on the side convex auxiliary support plate 21. The upper output shaft of the roll pressing drive motor 40 penetrates through the roll pressing working upper plate 30 and then protrudes upward, and a first synchronous pulley 90 is fixedly sleeved. The first roll pressing die 50 and the second roll pressing die 60 are sequentially arranged at intervals along the corresponding station positions on the lower surface of the roll pressing working upper plate 30. The upper output shafts of the first roll pressing die 50 and the second roll pressing die 60 respectively protrude upward and are sleeved with corresponding second synchronous pulleys 100. The synchronous belt 110 is enclosed and sleeved on the first synchronous pulley 90 and two groups of second synchronous pulleys 100.

[0033] Two groups of belt tensioning wheels 120 are respectively arranged in the corresponding outer regions of the enclosed synchronous belt 110, and the pressing rollers 121 of each group of belt tensioning wheel groups 120 are arranged closely against the outer surface of the synchronous belt 110 at the corresponding positions.

[0034] During specific implementation, the vertical frame 80 includes an upper plate 81 and two side vertical plates 82. The upper plate 81 is used to support the roll pressing working upper plate 30. The two side vertical plates 82 are respectively supported on the upper surface of the side convex auxiliary support plate 21. The side convex auxiliary support plate 21 and the bottom plate 20 are of an integral structure.

[0035] During specific implementation, the belt tensioning wheel set 120 includes a mounting base 122, a linear spring 123, a pressing roller 121, and a mounting shaft 124. A positioning hole 125 is provided at one end of the mounting base 122 in the length direction. The bolt 130 is fixedly installed at the corresponding mounting position on the upper plate 30 of the roller pressing work through the positioning hole 125. The pressing roller 121 is arranged on the upper surface of the mounting base 122 facing the synchronous belt. The pressing roller 121 is sleeved on the upper end of the mounting shaft 124 through a bearing 126. A long slot hole 127 is provided at the position of the mounting base 122 corresponding to the mounting shaft 124. The linear spring 123 is arranged in the long slot hole 127. The lower part of the mounting shaft 124 is inserted into the long slot hole 127. The linear spring 123 is horizontally arranged, and the movable end abuts against a partial area of the lower part of the mounting shaft 124, which enables the pressing roller 121 to press the synchronous belt 110 tightly.

[0036] A spring installation cavity 128 is further provided in the inner cavity of the mounting base 122. The spring installation cavity 128 communicates with the long slot hole 127. The linear spring 123 is plugged into the spring installation cavity 128, and the exposed opening of the spring installation cavity 128 is sealed by a locking screw 140. The movable end of the linear spring 123 is located in the long slot hole 127.

[0037] The end face of the mounting shaft 124 facing the linear spring 123 is a vertical plane 1241, which ensures that the elastic force of the linear spring 123 acts on the mounting shaft 124 reliably and stably.

[0038] A guiding block 129 is fixedly sleeved at the bottom of the mounting shaft 124. A concave long guiding groove 1221 is provided at the position of the bottom of the mounting base 122 corresponding to the guiding block 129. The long guiding groove 1221 ensures the reliable and stable movement of the mounting shaft and prevents it from rotating, thereby ensuring the reliable application of force by the linear spring.

[0039] During specific implementation, the positioning hole 125 is specifically an oval hole, which enables the position of the belt tensioning wheel set 120 to be adjusted slightly as needed.

[0040] The working principle is as follows. A roller pressing drive motor drives the first roller pressing die and the second roller pressing die to perform synchronous roller pressing operations, which saves the cost of one motor. And since the two groups of belt tensioning wheel sets are respectively arranged in the corresponding outer regions of the closed synchronous belt, the pressing rollers of each group of belt tensioning wheel sets are arranged closely against the outer surface of the synchronous belt at the corresponding positions, which can ensure that the transmission belt is in a tensioned state during the roller pressing work.
