Abstract
The utility model discloses a cold header which is especially suitable for processing steel balls, screws, and rivets, belonging to forging molding equipment. The cold header is characterized in that one end of a crankshaft 1 is provided with a pair of bevel gears 2, 3; a cam device is arranged on a driven bevel gear shaft 5; a scissors slide block 9 is vertically arranged on the roller shaft 10 of the driven roller 8 of the cam device. The utility model overcomes the defects of the prior art. Running friction coefficient and impact force among each component of a feed cutting mechanism are small, which enables the cold header to stably run, effectively reduces running noise, and enhances product quality and productivity.
Description
The utility model relates to a kind of Cold header, and especially for the Cold header of processing steel ball, screw and rivet, it belongs to forging forming equipment.It comprises the feeding shut-off mechanism that is made of bent axle, bevel gear, cam gear and scissors slide block.
The present Cold header that generally uses, its feeding shut-off mechanism adopt structure shown in Figure 2 usually: be connected with slide block 1 on the eccentric wheel of bent axle one end, have curvilinear shaped slots 4 on the slide block 1, roller 2 is set in the groove, scissors shaft 5 is housed on the Roller Shaft 3.When slide block 1 straight line moved, roller 2 was done interrupted sliding friction motion in groove 4, and then drove the scissors shaft 5 realization feeding cutting-off processes that scissors bit is housed.The operation friction and the impulsive force of this feeding material cutting mechanism are big, and the rate that operates steadily is low, and the machining accuracy of Cold header is greatly affected.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and proposes a kind of novel Cold header.The operation friction and the impulsive force of feeding shut-off mechanism of the present utility model are little, and degree of operating steadily height has improved the machining accuracy of Cold header greatly.
The purpose of this utility model can reach by following measure:
The utility model Cold header comprises the feeding shut-off mechanism that is made of bent axle, bevel gear, cam gear and scissors slide block.Its concrete structure is: an end of bent axle is equipped with a pair of bevel gear, on its driven bevel pinion axle cam gear is installed, and is vertically installed with the scissors slide block on the Roller Shaft of the roller follower of cam gear.Be provided with scissors bit in the scissors slip front.In addition, the cam that is installed in the cam gear on the driven bevel pinion axle can be a disc cam, and its roller follower can be the moving roller of flat sided straight.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a general structure plane of the present utility model.
Fig. 2 is the feeding shut-off mechanism partial sectional view of prior art Cold header.
Fig. 3 is a feeding shut-off mechanism section plan of the present utility model.
Fig. 4 is the cam face curve map of feeding shut-off mechanism of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
As Fig. 1, shown in Figure 3, the utility model comprises by bent axle 1, bevel gear 2,3 and cam gear, scissors slide block 9 and being constituted.Its concrete structure is that an end of bent axle 1 is equipped with a pair of bevel gear 2 and 3, is fixed on the driven bevel pinion axle 5 on the bearing block 4 cam gear is installed, and is vertically installed with scissors slide block 9 on the Roller Shaft 10 of the roller follower 8 of cam gear.The leading section of scissors slide block 9 is equipped with carbide bit 12.Cam gear comprises and is installed in the cam chair 6 of axle on 5, is fixed in cam 7, roller follower 8 and Roller Shaft 10 on cam chair 6 end faces.Wherein, cam 7, roller follower 8 can adopt disc cam and the moving roller of flat sided straight respectively.
When the utility model Cold header is worked, under the effect of bent axle 1, driven bevel pinion axle 5 drives cam 7 rotations, making roller follower 8 carry out continuous rolling moves, its Roller Shaft 10 corresponding mobile drive the scissors slide block 9 that is installed in the scissors take-up housing 11 and slide in its guide rail, thereby make the scissors bit 12 that is positioned at scissors slide block 9 front ends realize feeding cut-out work.
The utility model has following advantage compared to existing technology:
Coefficient of friction between each parts of feeding shut-off mechanism of the present utility model is little, and impulsive force reduces, Thereby greatly improved the service life of each parts, equipment has been operated steadily, reducing noise.
In a word, the utility model machining accuracy height, good product quality, be specially adapted to produce steel ball, The good cold pier equipment of screw and rivet.
