Detailed Implementation

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , 2 As shown, a double-roll extrusion press for sheet metal production includes two opposing uprights 100. A fixed roller 170 is positioned between the two uprights 100, and a movable roller 180 is positioned above the fixed roller 170. Both the fixed roller 170 and the movable roller 180 are connected to a rotary drive device 190, which is a geared rotary motor. The rotary drive device 190 drives the fixed roller 170 and the movable roller 180 to rotate in opposite directions, thereby extruding the material entering between the rollers. The uprights 100 include a first support portion 110 and a second support portion 120. The end of the fixed roller 170 is rotatably connected to the first support portion 110. A lifting drive device 121 is mounted on the second support portion 120, and the lifting drive device 121 is connected to a connecting member 122. The end of the movable roller 180 is rotatably connected to the connecting member 122. The lifting drive device 121 can drive the movable roller 180 to perform lifting movements and automatically complete the gap adjustment between the movable roller 180 and the fixed roller 170. In practical applications, the lifting drive device 121 can be equipped with various power devices such as pneumatic cylinders and hydraulic cylinders. In this embodiment, one of the connecting members 122 is also connected to a mounting bracket 123. The reduction geared rotary motor connected to the movable roller 180 is mounted on the mounting bracket 123 to ensure that the movable roller 180 always remains connected to the rotary drive device 190.

[0024] like Figure 2 , 3As shown in Figure 4, a guide rod assembly 140 for preventing the connector 122 from tilting and a limiting assembly 150 for preventing the movable roller 180 from axially moving are provided between the upright frame 100 and the connector 122. The guide rod assembly 140 includes a movable rod 141 and a sleeve 142 sleeved on the movable rod 141. The movable rod 141 and the sleeve 142 are fixedly connected to the upright frame 100 and the connector 122, respectively. The sleeve 142 is fixed to the second support part 120, and one end of the movable rod 141 is fixedly connected to the connector 122. There are four sets of guide rod assemblies 140, and the four sets of guide rod assemblies 140 are respectively connected to both ends of two connectors 122. The guide rod assembly 140 can effectively prevent the connector 122 from tilting, improve the connection stability between the connector 122 and the lifting drive device 121, and avoid equipment damage. The limiting component 150 includes two opposing limiting grooves 151, each connected to a slider 152. The limiting grooves 151 are V-shaped grooves. The support frame 100 also includes two vertical support portions 160. The connecting member 122 is located between the two vertical support portions 160. The two limiting grooves 151 are respectively located on opposite surfaces of the two vertical support portions 160, and the two sliders 152 are respectively located at both ends of the connecting member 122. Through the cooperation of the limiting grooves 151 and the sliders 152, axial movement of the movable roller 180 can be prevented, further improving the stability of the movable roller 180, while not affecting its lifting and lowering movement.

[0025] like Figure 3 As shown, a synchronous lifting assembly 130 is provided between the two connecting members 122. The synchronous lifting assembly 130 is used to ensure that the lifting amplitude of the two connecting members 122 is consistent, thereby ensuring that the adjustment amount at both ends of the movable roller 180 is consistent and that the gap between the movable roller 180 and the fixed roller 170 is uniform. The synchronous lifting assembly 130 includes two racks 131 and a connecting rod 132. Both ends of the connecting rod 132 are provided with gears 133, and the two gears 133 are respectively connected to the two racks 131. The two racks 131 are respectively set on the two uprights 100. Both ends of the connecting rod 132 are rotatably connected to the two connecting members 122. When one connecting member 122 is raised or lowered, the connecting rod 132 will rotate due to the interaction of the gears 133 and the racks 131. Both ends of the connecting rod 132 will move up and down simultaneously. Furthermore, the connecting rod 132 can drive the other connecting member 122 to move up and down, thereby realizing the synchronous lifting and lowering of the two connecting members 122. When adjusting the gap between rollers, the two lifting drive devices 121 operate simultaneously, and the synchronous lifting component 130 can counteract the effect of inconsistent driving amounts of the two lifting drive devices 121.

[0026] like Figure 1As shown, the embodiment further comprises a feeding conveyor belt 200 and a discharging conveyor belt 210, which are respectively arranged on two sides of the fixed roller 170, and the feeding conveyor belt 200 and the discharging conveyor belt 210 can conveniently convey the material into the fixed roller 170 and the movable roller 180 for extrusion.

[0027] The above embodiment is a preferred implementation manner of the utility model, and is not a limitation on the utility model, and any obvious replacement without departing from the utility model concept of the utility model is within the protection scope of the utility model.
