Embodiment 1

[0026] refer to figure 1 and figure 2 , a bar pulling device shown, including a support 1 and a pulling roller assembly, the pulling roller assembly includes an upper pulling roller 2, a lower pulling roller 3 and a driving device that drives the lower pulling roller 3 to rotate, and the upper pulling roller 2 is located at the bottom Just above the traction roller 3, an upper bearing 21 is installed on the rotating shaft of the upper traction roller 2, and a lower bearing 31 is installed on the rotating shaft of the lower traction roller 3. The opposite surface of 11 is provided with mounting groove 111 along the height direction of support plate 11, and upper bearing 21 and lower bearing 31 are installed in the mounting groove 111 at intervals up and down, and there is an elastic member pressed between upper bearing 21 and lower bearing 31 4. The elastic member 4 elastically props up the upper bearing 21, and the top of the support plate 11 is provided with an adjustment m...

Embodiment 2

[0036] refer to figure 2 , The difference between this embodiment and Embodiment 1 is that the adjusting part 5 is only a screw rod, and a cover plate 6 is provided on the notch of the installation groove 111, and the screw rod is screwed to the cover plate 6, and the cover plate 6 is provided with a screw hole , the bottom of the screw mandrel passes through the screw hole to offset the top of the upper bearing 21, and when the screw mandrel is rotated, the screw mandrel moves along the axial direction of the screw hole to realize lifting, thereby adjusting the height of the upper bearing 21 and the upper traction roller 2. In this embodiment The structure is simple and the cost is low.

Abstract

The invention discloses a bar draw gear, and belongs to the field of bar processing, which solves the technical problem that in the prior art, the bar draw gear is complicated in structure and only can deliver a single-specification bar. The bar draw gear comprises a bracket and a drawing roll subassembly, wherein the drawing roll subassembly comprises an upper drawing roll, a lower drawing roll and a driving device driving the lower driving roll to be rotated; an upper bearing is mounted on a rotating shaft of the upper drawing roll; a lower bearing is mounted on a rotating shaft of the lower drawing roll; two support plates are arranged on the bracket at intervals; mounting grooves are formed in the opposite sides of the support plates in the height directions of the support plates; the upper bearing and the lower bearing are mounted in the mounting grooves at intervals up and down; an elastic element is arranged between the upper bearing and the lower bearing; regulating elements capable of going up and down are arranged at the top parts of the support plates, and push down the top part of the upper bearing. The bar draw gear disclosed by the invention is applied to draw and feed of the bar.

Description

【Technical field】 [0001] The invention relates to a rod pulling device, which belongs to the field of rod processing. 【Background technique】 [0002] At present, the horizontal continuous casting process of copper alloy rods adopts the old-fashioned gear-shifting traction device or the automatic traction device using PLC as the main controller. [0003] The old-fashioned traction device uses a worm gear reducer to drive the shift fork to perform reciprocating motion, and the ratchet is driven to drive the traction roller to run, so as to achieve the purpose of copper rod traction. The device controls the traction speed by controlling the rotation speed of the excitation motor through the governor, and controls the pitch of the bar traction by adjusting the reciprocating distance of the fork. However, the device lacks controllability, and the speed of the equipment will change due to the voltage level, which will have a great impact on product quality. [0004] The automati...
