A semi-automatic straightening machine for I-shaped wheel

Abstract

The invention discloses a semi-automatic straightening machine of a spool and belongs to the field of spool straightening. The semi-automatic straightening machine of the spool comprises a rack, a hydraulic pump station, a hydraulic cylinder, a round pressing plate, a movable fixing frame and a bracket, wherein a semi-cylindrical groove is designed in the upper end face of the rack, top plates are disposed at two ends of the semi-cylindrical groove respectively, the hydraulic cylinder is disposed in middle of one top plate, the top end of a piston rod of the hydraulic cylinder is fixed at the circle center of the pressing plate, the bracket is fixed in the semi-cylindrical groove, a long semi-cylindrical groove is designed in middle of the bracket, the movable fixing frame is hinged to a plate surface through a hinge, a position of a lower pressing surface of the movable fixing frame, which corresponds to the long semi-cylindrical groove, is provided with a semi-circle pressing groove, and a locking supporting plate is fixed at the tail end of the movable fixing frame. According to the semi-automatic straightening machine of the spool, two sides of limiting protecting boards of the spool are extruded and straightened, the operation is simple, incomplete pressing or excessive pressing can be avoided, incomplete straightening of the spool or excessive downwards pressing is prevented, and thereby, the phenomenon that side plates of the spool are pressed to scroll ends and deformed can not occur.

Description

Technical field [0001] The invention belongs to the field of I-shaped wheel correction, and more specifically, relates to a semi-automatic I-shaped wheel correction machine. Background technique [0002] In the metal wire production industry such as copper wire and alloy wire, the I-shaped wheel is often used as a carrier for winding the wire, and some heat treatment processes are performed. During the heating process, the I-shaped wheel will be deformed by heat, so a correction is required I-shaped wheel deformation device, for mass-heated I-shaped wheels, there is a need for a correction device with simple structure, convenient operation, and mass correction of I-shaped wheel deformation. For example, Chinese patent 201310307054.8 discloses an I-shaped wheel. Although the wheel hydraulic correcting device can easily correct the spool, it has the following disadvantages. One is that it cannot well control the pressing distance of the hydraulic cylinder. In addition, the pressin...

Problems solved by technology

[0002] In the metal wire production industry such as copper wire and alloy wire, the I-shaped wheel is often used as the carrier of the wire, and some heat treatment processes are performed. During the heating process, the I-shaped wheel will be deformed by heat. Therefore, a correction is required. The device for deforming the I-shaped wheel needs a correction device that is simple in structure, easy to operate and capable of correcting the deformation of the I-shaped wheel in large quantities. For example, Chinese patent 201310307054.8 discloses an I-shaped wheel Although the wheel hydraulic correction device can easily correct the I-shaped wheel, it has the following defects. One is that it cannot well control the distance of the hydraulic cylinder.

And the pressing distance is manually controlled by the switch to press and stop the action of the hydraulic cylinder, which is prone to poor operation and accidents, and has high requirements for the operation of the operator, so it is easy to appear under-press or over-press, resulting in I-shaped The wheel is not corrected completely, or the transition is under pressure, and the side plate of the I-shaped wheel is pressed to the end of the reel until it is deformed; the second is that four hydraulic cylinders are required to work at the same time, and the cost is relatively high
