Abstract
The utility model discloses a feed anti-reverse device of a cold heading forming machine, which comprises a feed wheel fixedly arranged on a feed wheel shaft, a ratchet wheel and a driving swing arm movably sheathed on the feed wheel shaft, wherein a pawl for pushing the ratchet wheel to rotate is connected with the driving swing arm, the driving swing arm and a transmission part are connected with the feed wheel shaft for reciprocating swing, the feed wheel shaft is in rotatable connection with a feed seat through bearing supports, and the feed anti-reverse device is characterized in that the bearing supports are arranged in two positions, wherein a bearing adopted by the bearing support which is arranged near to the ratchet wheel is an anti-reverse one-way bearing, and the rotation direction of the anti-reverse one-way bearing is consistent with the rotation feed direction of the feed wheel. The feed anti-reverse device can prevent the backing phenomenon of the feed wheel due to reciprocating motion of the driving swing arm during the feed process and further avoid the insufficiency in feed length.
Description
[technical field]
The utility model relates to a kind of cold-heading molding machine, is specifically related to a kind of feeding anti-reversing clutch of cold-heading molding machine.
[background technology]
The cold-heading molding machine is a kind of the various metal wire rods of handling well to be carried out cold extrusion, makes the equipment of wire rod cold-heading molding in mould, is used to process various standards, non-standard securing member and the vapour accessory that rubs.The feeding of cold-heading molding machine is to move back and forth by driving swing arm; driving ratchet promotion ratchet-gear wheel intermittently rotates; drive drawing-inroller rotation carrying out feeding at last; in the above-mentioned feeding process; owing to drive the reciprocating motion of swing arm, when ratchet idle stroke (sliding on the back of tooth of ratchet at ratchet-gear wheel), ratchet-gear wheel reverse, drawing-inroller to a certain degree occur through regular meeting and retreat phenomenon; it is not enough feed length to take place like this, causes product quality defective.
[summary of the invention]
In view of the deficiency that background technology exists, the purpose of this utility model is intended to provide a kind of can preventing to retreat phenomenon because drive the drawing-inroller of swing arm reciprocating motion generation in the feeding process, thereby avoids the not enough cold-heading molding machine feeding anti-reversing clutch of feed length.
The utility model is implemented by following technical solution:
The feeding anti-reversing clutch of cold-heading molding machine, comprise the drawing-inroller that is fixedly installed on the parts feeding axle, ratchet-gear wheel and be movably set in driving swing arm on the parts feeding axle, the ratchet that promotes described ratchet-gear wheel rotation is connected with described driving swing arm, drive swing arm and drive disk assembly and be connected reciprocally swinging on the parts feeding axle, described parts feeding axle is rotatably connected by bearings and material feeding seat, it is characterized in that: described bearings is provided with two places, wherein the bearing that bearings adopted near described ratchet-gear wheel setting is anti-reverse unilateral bearing, and the rotation direction of anti-reverse unilateral bearing is consistent with the rotation feed direction of described drawing-inroller.
In the said structure, being provided with of anti-reverse unilateral bearing stopped fully because ratchet-gear wheel reverses the generation that causes the phenomenon that drawing-inroller retreats, thereby thoroughly avoided the not enough of feed length.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structure chart of the present utility model
[specific embodiment]
With reference to accompanying drawing 1, the feeding anti-reversing clutch of this kind cold-heading molding machine, comprise the drawing-inroller 1 that is fixedly installed on the parts feeding axle 4, ratchet-gear wheel 2 and be movably set in driving swing arm 3 on the parts feeding axle 4, the ratchet (not drawing among the figure) that promotes described ratchet-gear wheel 2 rotations is connected with described driving swing arm 3, drive swing arm 3 and be connected reciprocally swinging on the parts feeding axle 4 with drive disk assembly, described parts feeding axle 4 by about two place's bearings and material feeding seat 6 be rotatably connected, wherein the bearing that bearings adopted 5 that is provided with near described ratchet-gear wheel 2 is anti-reverse unilateral bearing, and the rotation direction of anti-reverse unilateral bearing is consistent with the rotation feed direction of described drawing-inroller 1.The feeding process of said apparatus is such, drive the swing of swing arm 3 forwards, promoting ratchet-gear wheel 2 by ratchet rotates, ratchet-gear wheel 2 drives parts feeding axle 4 again and feeding is carried out in drawing-inroller 1 rotation, when driving swing arm 3 reverse swings, because the existence of anti-reverse unilateral bearing 5, so ratchet-gear wheel 2, parts feeding axle 4 and drawing-inroller 1 can reverse rollbacks, thereby avoided the not enough situation of feed length to take place, guaranteed the quality of cold-heading product.
Claims (1)
1. the feeding anti-reversing clutch of cold-heading molding machine, comprise the drawing-inroller that is fixedly installed on the parts feeding axle, ratchet-gear wheel and be movably set in driving swing arm on the parts feeding axle, the ratchet that promotes described ratchet-gear wheel rotation is connected with described driving swing arm, drive swing arm and drive disk assembly and be connected reciprocally swinging on the parts feeding axle, described parts feeding axle is rotatably connected by bearings and material feeding seat, it is characterized in that: described bearings is provided with two places, wherein the bearing that bearings adopted near described ratchet-gear wheel setting is anti-reverse unilateral bearing, and the rotation direction of anti-reverse unilateral bearing is consistent with the rotation feed direction of described drawing-inroller.
