Abstract
The utility model discloses a pulling device, in particular to the pulling device for a bearing. The pulling device for quickly dismounting and mounting the bearing of a hot straightening machine comprises a base, a front end plate, a rear end plate, four pull rods, a support roller bracket and a hydraulic top bracket, wherein the front end plate and the rear end plate are vertically arranged on the base; the front end plate is provided with a through hole for accommodating the bearing; the four pull rods are respectively positioned at four corners of the front end plate and the rear end plate and can be connected with the front end plate and the rear end plate in a front-back moving manner; the supporting roller bracket is positioned in front of the front end plate; the hydraulic top bracket is positioned between the front end plate and the rear end plate; and a hydraulic top is arranged on the hydraulic top bracket. According to the pulling device, the work efficiency and the work quality of bearing dismounting and mounting work are improved and the safety of bearing dismounting and mounting work is improved.
Description
Technical field
The utility model relates to and draws the horse device, and what relate in particular to that a kind of bearing uses draws the horse device.
Background technology
Thermal straightening machine is to be indispensable core on the steel rolling production-line, plays crucial effects.Be characterized in device fabrication precision height, complex structure, the operating temperature height, single devices is heavy, assembly technology complexity, required precision height.
Thermal straightening machine is at the disassembling, assembling and replacing that carries out whole parts under the situation of work one-period with regard to machine under needing.Thermal straightening machine on the production line assembles this work and exists a lot of weak points at present.As working condition, detection means, technical specification can not satisfy the high-quality assembling of thermal straightening machine far away.
Current, remove the thermal straightening machine bearing and be used man-hour 5 people/8 and hour can only remove 10 cover bearings.11 roller thermal straightening machines have 142 bearings just needs 5 people/80 hour, the old-fashioned method that adopts when returning dress thermal straightening machine supporting roller bearing seat is beaten bump with very thick copper rod to bearing block and is forced bearing block to return to install to the position, will cause connecting shaft bearing gross distortion like this and also can make high-accuracy piece bearing seating face form rough result, have a strong impact on the service life of the flattening precision and the equipment of sheet material.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and provides a kind of heat rectification machine bearing fast assembling-disassembling with drawing the horse device.The utility model improves bearing dismantling operating efficiency and work quality, has improved the security of bearing dismantling work.
The utility model is achieved in that a kind of heat rectification machine bearing fast assembling-disassembling with drawing the horse device, and it comprises a base, and it also comprises and being arranged on the base:
Forward and backward end plate, they vertically are arranged on the base, and front end-plate is provided with the through hole that holds bearing;
Four pull bars, they are divided into four jiaos that are positioned at the front and back end plate, and end plate before and after can connecting movably forward and backward;
A backing roll carriage and a hydraulic pressure jacking frame, described backing roll carriage are positioned at front end-plate side before, and described hydraulic pressure jacking chord position which is provided with a hydraulic pressure top between forward and backward end plate.
The utility model backing roll all will enter fast hydraulic pressure and draw horse equipment from moving to slide into, the automatic centering, plane with clamp chucking bearing, the primer fluid press pump, the reversing valve operated oil cylinder that makes is reciprocating, thereby simple, quick, can guarantee the integrity of bearing again and bearing is pulled out from roller.
More reasonable with the assembling bearing by the utility model dismounting, safety both can guarantee to alleviate personnel labor, can guarantee bearing indeformable, injury-free in the process of pulling out again, utilized again.Not only guaranteed straightener roller box bearing dismantling quality, changed old-fashioned dismounting process and improved the security of dismounting greatly, used the special bearing fast hydraulic pressure to draw the horse isolated plant to have certain experiences and dissemination similar straightener roller box bearing dismantling.
Description of drawings
Below, in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is the utility model schematic diagram.
The specific embodiment
As shown in Figure 1, a kind of heat rectification machine bearing fast assembling-disassembling is with drawing the horse device, and it comprises a base 1, and it also comprises and being arranged on the base 1:
Forward and backward end plate 2,3, they vertically are arranged on the base 1, and front end-plate 2 is provided with the through hole that holds bearing;
Four pull bars 7, they are divided into four jiaos that are positioned at front and back end plate 2,3, and end plate 2,3 before and after can connecting movably forward and backward;
A backing roll carriage 4 and a hydraulic pressure jacking frame 5, described backing roll carriage 4 are positioned at front end-plate 5 side before, and described hydraulic pressure jacking frame 5 which is provided with a hydraulic pressure top 6 between forward and backward end plate 2,3.
