Description

Technical Field

[0001] The utility model relates to a processing device for shaft end sheaths, in particular to a device for processing anti-slip grooves on shaft end sheaths. Background Art

[0002] The shaft end sheath is a common device used in bearings. In order to prevent the rubber inside the sheath from slipping, anti-slip grooves need to be stamped on the working cylinder of the shaft end sheath. The existing process uses upper and lower mating stamping, which needs to be carried out multiple times, resulting in obvious transition marks on the stamping edge. Position conversion is also required in the middle, making the operation troublesome and the accuracy low. In order to facilitate the production of shaft end sheaths and improve the accuracy, a device for processing shaft end sheaths based on the squeezing and rolling method needs to be designed. Summary of the Invention

[0003] The utility model is directed at the existing process of using upper and lower mating stamping for production, which needs to be carried out multiple times, resulting in obvious transition marks on the stamping edge. Position conversion is also required in the middle, making the operation troublesome and the accuracy low. A device for processing anti-slip grooves on shaft end sheaths based on the squeezing and rolling method is designed.

[0004] The utility model provides a device for processing anti-slip grooves on shaft end sheaths, including: a turntable, a driving die, a downward pressing device, a horizontal pressing table, and a driven die;

[0005] The driving die is arranged on the rotating shaft of the turntable, the downward pressing device is arranged above the driving die, and the working end of the downward pressing device cooperates with the driving die;

[0006] The horizontal pressing table is arranged on the side of the turntable, a rotating shaft is arranged on the horizontal pressing table, the driven die is sleeved on the rotating shaft, and the driven die cooperates with the driving die;

[0007] The central axis of the rotating shaft of the turntable is on the same axis as the telescopic axis of the downward pressing device;

[0008] The top surface of the driving die is on the same horizontal plane as the top surface of the driven die.

[0009] The die patterns of the driving die and the driven die are set according to the shape required for the anti-slip grooves of the finished shaft end sheath.

[0010] Preferably, the downward pressing device includes: a telescopic cylinder, a pressing cover, and an inner cover;

[0011] The pressing cover is in the shape of a cylindrical cover, the inner cover is installed inside the cover, the pressing cover and the inner cover are coaxial and rotate relative to each other; the outer top surface of the pressing cover is fixedly connected to the telescopic end of the telescopic cylinder;

[0012] The telescopic cylinder is fixed above the driving die through a frame, and the telescopic end faces downward;

[0013] A circle of protrusions is arranged along the edge of the bottom surface of the inner cover.

[0014] Since the inner wall of the side wall of the shaft end sheath to be processed also needs to be processed together or in cooperation with the outer wall. Therefore, the diameter of the shaft end sheath to be processed is larger than that of the active mold, that is, during processing, the central axis of the shaft end sheath to be processed does not overlap with the central axis of the active mold, and due to the extrusion of the driven mold, the shaft end sheath to be processed will keep sliding on the active mold during processing. Therefore, the use of the protrusion can reduce the friction area between the shaft end sheath to be processed and the inner cover, thereby reducing the influence of friction on processing.

[0015] Preferably, the diameter of the inner cover is greater than or equal to the diameter of the top surface of the active mold.

[0016] Preferably, the horizontal pressing table includes: a horizontal sliding table, a telescopic oil cylinder, a rotating shaft bracket, and an adjusting rotating shaft;

[0017] The sliding axis of the horizontal sliding table passes through the central axis of the turntable. The surface adjacent to the turntable is set as the first end, and the surface far from the turntable is set as the second end;

[0018] The telescopic oil cylinder is arranged on the second end. The telescopic oil cylinder is relatively fixed to the fixed part of the horizontal sliding table through a bracket, and the telescopic end of the telescopic oil cylinder is in transmission with the sliding part of the horizontal sliding table to push the sliding part to slide;

[0019] The rotating shaft bracket is fixed on the top of the sliding part of the horizontal sliding table;

[0020] The rotating shaft bracket is in the shape of a C-shaped table, and the opening part faces the turntable;

[0021] The adjusting rotating shaft is arranged in the opening of the rotating shaft bracket and penetrates through the top surface of the rotating shaft bracket;

[0022] The driven mold is sleeved inside the adjusting rotating shaft;

[0023] The through hole on the top surface of the rotating shaft bracket is an internal thread hole;

[0024] The upper section of the adjusting rotating shaft is a threaded rod, and the adjusting rotating shaft cooperates with the rotating shaft bracket to adjust the vertical height of the driven mold.

[0025] Preferably, the adjusting rotating shaft includes:

[0026] A hollow threaded rod, a positioning rod, and a bearing turntable;

[0027] The positioning rod is fixed on the rotating shaft bracket. The hollow threaded rod is sleeved on the positioning rod. The hollow threaded rod is an external threaded rod, and the thread of the hollow threaded rod cooperates with the through hole of the rotating shaft bracket;

[0028] The inner ring of the bearing turntable is fixed to the hollow threaded rod, and the outer ring cooperates with the driven mold.

[0029] Preferably, a protective sleeve is also sleeved on the turntable. The vertical height of the upper edge of the protective sleeve is greater than the supporting part of the lower edge of the shaft end sheath in the driving die for the shaft end, and the vertical height of the upper edge of the protective sleeve is less than the vertical setting height of the die pattern in the driving die.

[0030] The device is used as follows: Place the shaft end sheath to be processed on the driving die. The telescopic cylinder extends, and the pressing cover presses above the shaft end sheath to be processed. The shaft end sheath to be processed is positioned in terms of vertical height through the cooperation of the inner cover and the driving die to avoid height errors during extrusion processing. Then the turntable rotates. Due to the assistance of the inner cover, the shaft end sheath to be processed rotates together with the driving die. At the same time, the driven die of the horizontal pressing table part approaches the driving die, and the driving die and the driven die cooperate to extrude the shaft end sheath to be processed inside and outside, and process the shaft end sheath to be processed until the shaft end sheath to be processed is completed and becomes the target product.

[0031] After the processing is completed, the horizontal pressing table returns to its original position, the turntable decelerates and stops rotating, and finally the telescopic cylinder retracts and returns to its original position, waiting for blanking and loading.

[0032] The beneficial effects of the present utility model are as follows: A device for processing anti-slip grooves on the shaft end sheath based on the extrusion rolling method is provided, which is simple to operate, has high precision, and is convenient for production compared with the traditional stamping method.
