Technical field
The invention belongs to the metallic article production technical field, relate to the long-pending cable reel on a kind of wire drawing machine, group drum on the long-pending cable reel of specifically a kind of double-cylinder type.
Background technology
Along with the development of Steel Wire Products Industry, at a high speed, efficiently, low-cost, Technological adaptability become pursuing one's goal of manufacturing enterprise by force.Wire drawing machine is a kind of plant equipment of extensive use in industries such as machine-building, five metals processing, petrochemical industry, electric wire, it is used for that wire rod or bar are carried out drawing handles, and makes diameter, circularity, inner structure, surface smoothness and the aligning degree of wire rod or bar all reach the raw material processing requirements that metallic article production such as standard component needs.
On wire drawing machine, in order to realize long-pending line or the unwrapping wire requirement of steel wire on long-pending cable reel, long-pending line adjusting device must be arranged, dialling drum then is the important component part of long-pending line adjusting device.Because job specification determines, dial drum and must have advantages such as use is reliable, easy to adjust, if design improperly, certainly will influence production in the use.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the drum of dialling on the long-pending cable reel of a kind of double-cylinder type is provided, this group drum is used for steel wire is wound into long-pending cable reel from the following long-pending cable reel transfer that double-cylinder type amasss cable reel, it is simple in structure, ingenious, reasonable, can be when the full line of admission machine I-beam wheel receipts be changed I-beam wheel, make wire drawing machine not out of service, effectively enhance productivity.
According to technical scheme provided by the invention: dial drum on the long-pending cable reel of a kind of double-cylinder type, it is characterized in that: comprise the chassis, the periphery on chassis is provided with and is used to install the clutch seat of clutch and the wheel stand that is used to install guide wheel assembly; Described clutch comprises brake ribbon, bearing, screw rod, spring base, spring and knurled nut, bearing is installed on the clutch seat, screw rod slidably but be contained in the bearing un-rotatably, screw rod relies on the key restriction on it to rotate, described knurled nut is assemblied in the tail end of screw rod, described spring housing is at the screw rod rear portion, spring one end withstands the knurled nut by a spring base, the spring other end withstands bearing by another spring base, described brake ribbon is centered around the periphery on bottom, chassis and base top, brake ribbon one end and bearing are hinged, and the front end of the brake ribbon other end and described screw rod is hinged; Described guide wheel assembly comprises guide roller and wheel shaft, and wheel shaft is fixedly mounted on the wheel stand, and described guide roller is installed in rotation on the wheel shaft by bearing.
As a further improvement on the present invention, the end of described wheel shaft encapsulates by end cap, on the described guide roller wheel cover is installed.
As a further improvement on the present invention, the baffle plate that can follow the synchronous rotation in chassis is installed on the described wheel stand.Described baffle plate can with matching near switch in its vicinity is set, when dialling drum and rotate, detect the rotation direction of dialling drum near switch by baffle plate, and send signal and give controller, so that regulate take-up speed.
The present invention compared with prior art, advantage is: simple in structure, ingenious, reasonable, can when the admission machine I-beam wheel is received full line and changed I-beam wheel, make wire drawing machine not out of service, effectively enhance productivity.

The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: described group of drum is applied on the long-pending cable reel of double-cylinder type, and it is used to realize long-pending line or the unwrapping wire requirement of steel wire on long-pending cable reel.The drum of dialling among the embodiment mainly is made up of parts such as chassis 1, bearing 3, spring 4, knurled nut 5, screw rod 6, spring base 7, brake ribbon 8, baffle plate 9, wheel cover 10, guide roller 11, wheel shaft 13 and end caps 14.
As Fig. 1 ~ shown in Figure 3, the periphery on chassis 1 is provided with and is used to the wheel stand 12 the clutch seat 2 of clutch being installed and being used to install guide wheel assembly; Described clutch is mainly by brake ribbon 8, bearing 3, screw rod 6, spring base 7, spring 4 and knurled nut 5 form, bearing 3 is installed on the clutch seat 2 by screw, screw rod 6 slidably but be contained in un-rotatably in the bearing 3, screw rod 6 relies on the key restriction on it to rotate, described knurled nut 5 is assemblied in the tail end of screw rod 6, described spring 4 is enclosed within screw rod 6 rear portions, spring 4 one ends withstand knurled nut 5 by a spring base 7, spring 4 other ends withstand bearing 3 by another spring base 7, described brake ribbon 8 is centered around the periphery on 1 bottom, chassis and base 2 tops, brake ribbon 8 one ends and bearing 3 are hinged, and the front end of brake ribbon 8 other ends and described screw rod 6 is hinged.Rotation knurled nut 5 gives bearing 3 application of forces by spring 4, can make the interior gradually receipts of brake ribbon 8, thereby makes group drum connect transmission with following long-pending cable reel.Described guide wheel assembly comprises guide roller 11 and wheel shaft 13, and wheel shaft 13 is fixedly mounted on the wheel stand 12 by nut, and described guide roller 11 is installed in rotation on the wheel shaft 13 by bearing.
As Fig. 1 ~ shown in Figure 3, the end of described wheel shaft 13 is by end cap 14 encapsulation, and end cap 14 can prevent that extraneous dust dirt from entering, and guarantees that guide roller 11 rotates flexibly; The wheel cover 10 that shields also is installed on the described guide roller 11.
In addition, as shown in Figure 1 and Figure 2, also be equipped with on the described wheel stand 11 and can follow the baffle plate 9 that rotate synchronously on chassis 1 by screw.Described baffle plate 9 can with matching near switch in its vicinity is set, when dialling drum and rotate, detect the rotation direction of dialling drum near switch by baffle plate 9, and send signal and give controller, so that regulate take-up speed.
During concrete the application, dialling drum is arranged on the following long-pending cable reel of the long-pending cable reel of double-cylinder type and upward amasss between the cable reel, the clutch of dialling on the drum is used to make group drum to separate or connect with following long-pending cable reel, the guide wheel assembly of dialling on the drum is used for steel wire being wound into long-pending cable reel from amassing the cable reel transfer down, upward long-pending cable reel unwrapping wire under the pulling of admission machine.
