Automatic roll-pressing machine for holding rack

Abstract

The invention relates to an automatic roll-pressing machine for a holding rack, which comprises a transverse feeding mechanism, a support seat, a roller, a motor, a tray, a loading mechanism, an unloading mechanism, an alignment cylinder, a shift fork, a loading passage, an unloading passage, a machine frame, a drive shaft, a conveying mechanism, a returning mechanism and a rolling shaft, wherein the support seat is fixedly connected with the transverse feeding mechanism; the roller is connected with the support seat; the tray is fixedly connected with the machine frame through a support plate; the motor is in transmission connection with the tray; a plurality of accommodation holes uniformly distributed in a circumferential direction are formed in the tray; the loading mechanism comprises a loading mounting rack, a loading cylinder and a loading sleeve; the unloading mechanism comprises an unloading mounting rack, an unloading cylinder and an unloading sleeve; and the conveying mechanism comprises a conveying mounting plate, a conveying cylinder and a conveying sleeve. The automatic roll-pressing machine avoids safety accidents, saves energy and improves product quality.

Description

technical field [0001] The invention relates to a rolling machine, in particular to an automatic rolling machine for cages used in needle roller bearings. Background technique [0002] At present, the rolling forming process of M-shaped cage in the industry is carried out on ordinary lathes. The operator puts the workpiece on the roller that rotates with the main shaft with one hand, and rotates the handle of the small tool holder with the other hand to install it on the The rolling wheel on the tool rest pushes to the workpiece. When the rolling wheel, workpiece and roller contact in the horizontal direction at the same time, the rolling wheel starts to rotate while feeding. When the rolling reaches the specified window hole lock amount (this lock The amount is controlled by the feed scale of the handle of the small knife rest), the operator rotates the handle of the small knife rest in reverse with one hand, the rolling wheel is retracted, and the other hand unloads the ro...

Problems solved by technology

[0002] At present, the rolling forming process of M-shaped cage in the industry is carried out on ordinary lathes. The operator puts the workpiece on the roller that rotates with the main shaft with one hand, and rotates the handle of the small tool holder with the other hand to install it on the The rolling wheel on the tool rest pushes to the workpiece. When the rolling wheel, workpiece and roller contact in the horizontal direction at the same time, the rolling wheel starts to rotate while feeding. When the rolling reaches the specified window hole lock amount (this lock The amount is controlled by the feed scale of the handle of the small knife rest), the operator rotates the handle of the small knife rest in reverse with one hand, the rolling wheel is retracted, and the other hand unloads the rolled workpiece from the rotating roller, and then Then insert the workpiece to be rolled and enter the next cycle. The problems of this rolling method are as follows: the operator performs frequent loading and unloading operations on the rotating roller. Stable, prone to fatigue, and cause safety accidents; relying on manual control of the feed speed and feed stroke, the plastic deformation speed and plastic deformation amount of the workpiece are inconsistent, which eventually leads to the out-of-tolerance internal locking of the window hole, resulting in missing needles or stuck needles Phenomenon; the power of ordinary lathes is 7.5KW, the reactive power loss is too large, and energy is wasted
