[0016] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0017] See also Figures 1 to 6The utility model provides a material pulling mechanism for the production of compressor spiral blades, which is installed on a punching machine and includes a horizontally arranged flat plate 1, a stacking plate 2 is fittedly installed on the upper side of the right end of the flat plate 1, a groove for thin steel to pass through is opened at the lower end of the stacking plate 2, and the thin steel passes through the groove in a close relationship with the flat plate to ensure that the thin steel passes straightly, side plates 3 are symmetrically arranged on the front and rear sides of the flat plate 1, and a first mounting block 4 which is T-shaped and can be mounted on the workbench of the punching machine is arranged on the right end of the two side plates 3, a motor 5 is arranged on the upper end of the flat plate 1, and an upper roller 6 is keyed on the output shaft of the motor 5, and a lower roller 7 which is transmission-connected with the upper roller 6 and passes through the flat plate is rotatably arranged between the two side plates 3, and the thin steel moves to the left through the rolling upper roller 6 and lower roller 7. A frame plate is longitudinally arranged on the left side of the upper end of the two side plates 3, and a cylinder 8 is arranged downward on the upper end of the frame plate. The piston rod end of the cylinder 8 is connected with a cutter 9 for cutting thin steel. The thin steel pulled over will be scattered all over the ground. The cylinder drives the cutter to cut the thin steel pulled over, so that the thin steel can be collected in sections. The motor drives the upper roller to rotate, and the upper roller drives the lower roller to rotate in the opposite direction through two gears. The thin steel is formed into a rotary sheet after stamping. The thin steel after punching moves to the left through the two rollers, thereby pulling the unpunched thin steel to move to the left. It has a small size, occupies a small space, has a simple structure, and is easy to operate and maintain.

[0018] The rear sides of the upper roller 6 and the lower roller 7 are coaxially connected with gears, and the two gears are meshed with each other.

[0019] See also Figure 1 , Figure 5 , and also includes a pressing stop assembly 10, which includes a pressing wheel 10.1 twisted to the two side plates 3 through a rotating shaft, a longitudinal plate 10.2 for pressing the thin steel material is longitudinally and elastically arranged above the flat plate 1, a second mounting block 10.3 that can be mounted on the punch of the punching machine is arranged above the pressing wheel 10.1, and a lower pressing rod 10.4 for pressing and rotating the pressing wheel 10.1 is arranged on the second mounting block 10.3. The lower pressing rod is a screw rod screwed to the second mounting block and its bottom is semicircular. The lower pressing rod can be adjusted up and down by rotating the screw rod, and the pressing wheel pressed and rotated by the lower pressing rod drives the longitudinal plate to press down the thin steel material passing below, thereby pressing and stopping the thin steel material, so that the punching machine can punch out the rotary blade.

[0020] The cross-sectional line of the pressing wheel 10.1 is composed of an arc line coaxially arranged on the upper side with the rotating shaft connected to a horizontal line on the lower side. The outer ring of the pressing wheel 10.1 is obliquely provided with an extension plate, and the lower pressing rod 10.4 rotates the pressing wheel 10.1 by pressing the extension plate. When the punch of the punching machine descends with the lower pressing rod, the lower pressing rod rotates the pressing wheel by pressing the extension plate.

[0021] The upper ends of the two side plates 3 are horizontally provided with a cover plate covering the motor 5, the upper roller 6, and the lower roller 7. The cover plate setting can prevent sundries from being rolled into the motor and the roller, thereby damaging the equipment.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention.
