Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a double-roller clamping spinning machine. Background Art

[0002] The spinning machine is a metal plastic forming machine. Its bed is equipped with an AC servo system, enabling automatic processing and control. It is a multifunctional, general-purpose device with high precision and reliability. It also features CAD drawing programming, core mold copying, and recording and replay functions.

[0003] According to a disclosed double-wheel spinning machine (Announcement No.: CN221675456U), the above application controls the lateral and longitudinal movement of the wheels respectively through the setting of the first screw transmission mechanism and the second screw transmission mechanism. At the same time, the wheels on both sides of the main shaft move synchronously, ensuring the processing accuracy. The adjustable setting of the tail rod connecting seat and the tail rod fixing seat can process large workpieces and fine-tune the position at the same time, thereby improving the clamping stability. The device is suitable for industrial production and has strong practicality.

[0004] However, in actual use of the above equipment, the size of the tail rod is fixed. When encountering some larger workpieces, the tail rod against the center of the workpiece is prone to insufficient friction, resulting in a decrease in the stability of the workpiece during processing. In view of this, we proposed a double-roller clamping spinning machine. Utility Model Content

At this time, the arc groove rotates with the turntable, so that the movement of the slide rod drives the fixed plate to move.

[0010] Preferably, a slider is provided on the outer wall of the slide rod, and the slider is slidably connected to the inner wall of the arc groove. The turntable is rotatably connected to the inner wall of the sleeve, so that when the turntable rotates, the arc groove rotates with the turntable, thereby causing the slider to rotate in the arc groove. Since the sleeve remains fixed, the fixed plate will be driven to rise when the slider moves.

[0011] Preferably, there are four groups of sliding rods, which are distributed in a circular array on the outer wall of the shell, and the ends of the sliding rods away from the shell are fixedly connected to a fixed plate, and the outer wall of the fixed plate is provided with a rotating wheel so that the workpiece can rotate during spinning.

[0014] Compared with the prior art, the present invention provides a double-roller clamping spinning machine with the following beneficial effects:

[0015] 1. In this double-roller clamping spinning machine, when the turntable moves, the moving tooth plate can drive the transmission gear to rotate, thereby rotating the pulley, and driving the turntable to rotate through the transmission belt.

[0016] 2. The double-roller clamping spinning machine fixes the workpiece by clamping the push rod and the pressure plate, and adjusts the motor to rotate the bidirectional screw, so that the slide drives the swivel to move, so that the pressure roller can spin workpieces of different diameters. The roller on the limit plate can make the swivel move more smoothly. At the same time, the movement of the limit plate drives the movement of the limit tooth plate, so that the limit gear rotates. At this time, the limit tooth plates on the two sets of swivels are engaged with the limit gears at the same time, so that the distance the swivel moves is always consistent, so that the workpiece is subjected to more uniform force during spinning.

At this time, the arc groove 87 rotates with the turntable 86, so that the slide bar 88 moves and drives the fixed plate 89 to move, so that the fixed plate 89 and the casing 85 can better fit the workpieces of different diameters, so that the electric push rod 3 can push the workpiece to be clamped more tightly with the casing 85, so that the workpiece remains in the center position.

[0028] In an embodiment of the present utility model, a slider is provided on the outer wall of the slide rod 88, and the slider is slidably connected to the inner wall of the arc groove 87.
