Abstract
The utility model relates to a rotation feeding mechanism which comprises a bearing machine base, a crank gear, a connecting rod and a rack. The crank gear, the connecting rod and the rack are all installed in a corresponding groove formed in the bearing machine base, the crank gear is connected with a crank mechanism of an external device, the first end of the connecting rod is fixedly connected with a fixing shaft of the crank gear, the second end of the connecting rod is provided with a progressive gear, and the progressive gear is meshed with the rack. The rotation feeding mechanism has the advantages of being simple in structure, tight in connection with the external device and stable in rotation feeding movement, improving the accuracy, being large in tube damaging deformation, improving the cold rolling efficiency of a cold rolling machine, and improving the production benefit to some extent in the practical application.
Description
Technical field
The utility model relates to a kind of revolution feed mechanism.
Background technology
Cold pilger mill is to utilize annular distance shape hollow forging to be carried out to the process equipment of cold conditions rolling, these facility have cogging performance preferably, non-ferrous metal seamless pipe that also can the rolling general precision, the primary structure of cold pilger mill comprises lathe bed, revolution feed mechanism, frame, main motor, plug, transmission system and electrical system etc., wherein existing revolution feed mechanism is generally single revolution and singly sends formula mechanism to, but its shortcoming is rolling district flow of metal and stressed even not, rolling accuracy is not high, does not also have product or the method that can address these problems to occur at present.
The utility model content
The purpose of this utility model is to provide a kind of revolution feed mechanism, simple in structure, and stable action is sent in revolution to, manages bad deflection large, has improved the cold rolling efficiency of cold pilger mill, to overcome the currently available technology above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of revolution feed mechanism, comprise carrying support, crank gear, connecting rod and tooth bar, described crank gear, connecting rod and tooth bar all are installed in the corresponding recesses arranged in described carrying support, described crank gear is connected with the crank mechanism of external device (ED), the first end of described connecting rod is fixedly connected with the fixed axis of described crank gear, the second end of described connecting rod is provided with the gear that goes forward one by one, and the described wheel and rack that goes forward one by one is meshed.
Above-mentioned revolution feed mechanism, described carrying support bottom is provided with extension.
Above-mentioned revolution feed mechanism, described extension is provided with the horn shape draw-in groove equably.
Above-mentioned revolution feed mechanism, also be provided with support in described carrying support, and the axis of described gear is installed on described support.
The beneficial effects of the utility model are: simple in structure, tightr with being connected between external device (ED), stable action is sent in revolution to, improved precision, manage bad deflection large, improved the cold rolling efficiency of cold pilger mill, also improved to a certain extent in actual applications productivity effect.
The accompanying drawing explanation
Below with reference to the accompanying drawings the utility model is described in further detail.
Fig. 1 is the overall structure schematic diagram of the described revolution feed mechanism of the utility model embodiment.
In figure:
1, carrying support; 2, crank gear; 3, connecting rod; 4, tooth bar; 5, first end; 6, the second end; 7, the gear that goes forward one by one; 8, extension; 9, horn shape draw-in groove; 10, support.
The specific embodiment
As shown in Figure 1, the described a kind of revolution feed mechanism of the utility model embodiment, comprise carrying support 1, crank gear 2, connecting rod 3 and tooth bar 4, described crank gear 2, connecting rod 3 and tooth bar 4 all are installed in the corresponding recesses of described carrying support 1 interior setting, described crank gear 2 is connected with the crank mechanism of external device (ED), the first end 5 of described connecting rod 3 is fixedly connected with the fixed axis of described crank gear 2, the second end 6 of described connecting rod 3 is provided with the gear 7 that goes forward one by one, and the described gear 7 that goes forward one by one is meshed with tooth bar 4, described carrying support 1 bottom is provided with extension 8, described extension 8 is provided with horn shape draw-in groove 9 equably, also be provided with support 10 in described carrying support 1, the described axis that goes forward one by one gear 7 is installed on described support 10.
The described revolution feed mechanism of the utility model embodiment is the single feed mechanism of single revolution, the pipe of sending into this mechanism by between topping roll hole and bottom roll hole open roller power after deflection larger, precision is high; The horn shape draw-in groove 9 of described extension 8 and the projection which is provided with and external device (ED) corresponding position interlocking, can increase the integrally-built compactness of cold pilger mill, and its stability also is greatly improved; The described gear 7 that goes forward one by one increases it in the process of advancing can prevent that described going forward one by one from sliding phenomenon occurring between gear 7 and tooth bar 4.
Above-described embodiment is only for the utility model creation example clearly is described, and not the utility model is created the restriction of the specific embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.All any apparent variations of being extended out within spirit of the present utility model and principle or change are still among the utility model is created the protection domain of claim.
