Abstract
The utility model relates to a sharpening machine pushes away steel hydro-cylinder device belongs to metallurgical machinery technical field. The steel billet feeding device comprises an oil cylinder and a steel pushing cross beam, wherein the oil cylinder is arranged on a support frame, the end part of a piston rod of the oil cylinder is arranged in the steel pushing cross beam, the contact surface of the oil cylinder and the contact surface of the oil cylinder is in spherical contact, a guide rod is fixed on the steel pushing cross beam and penetrates through the support frame, and the oil cylinder piston rod drives the steel pushing cross beam to push a steel billet when acting, so that the blanking of the steel billet is realized. The end parts of the piston rods of the oil cylinders are hooped in a pair of half shafts, the steel pushing cross beam is provided with a circular groove matched with the two half shafts, and the two half shafts are arranged in the circular groove. This application changes the contact surface of the tip of hydro-cylinder piston rod and pushing away the steel crossbeam into the sphere contact by the plane contact, not only reforms transform with low costsly, has avoided the hydro-cylinder sealed to damage moreover to appear the oil leak or push away the cracked phenomenon of messenger's hydro-cylinder bolt firmly, has improved the life and the production efficiency of hydro-cylinder.
Description
Technical Field
The utility model relates to a sharpening machine pushes away steel hydro-cylinder device belongs to metallurgical machinery technical field.
Background
The sharpening machine is a device for repairing the surface or the defect part of a casting blank after the casting blank is taken off line, and the normal operation of the device plays an important role in ensuring the production of the next procedure (steel rolling). Therefore, the sharpening machine used on line has higher and higher use requirements on the sharpening machine due to the continuous increase of the specifications of casting blanks; the production is directly influenced by the overhaul after the fault occurs. The steel pushing oil cylinder device is a part of key equipment of the sharpening machine, the steel pushing oil cylinder device is installed on the side face of the sharpening machine, after the sharpening of the casting blank is completed, an operation table is opened to control an electromagnetic valve of the steel pushing oil cylinder to be electrified, oil flows to the oil cylinder through a hydraulic valve block and then is pushed out by a piston rod, and the end face of the piston rod pushes a steel cross beam to push the casting blank to a blanking table. The end face of the piston rod is in plane contact with the contact surface of the steel pushing beam, and the steel pushing beam and the casting blank are not in the central position, so that the piston rod is unbalanced in stress, and the oil cylinder is damaged in sealing and oil leakage occurs; or the forced bottom plate bolt is broken due to hard pushing, and the steel pushing oil cylinder device has frequent faults, so that the sharpening machine must be stopped to use, and the production efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a coping machine pushes away steel hydro-cylinder device is provided to above-mentioned prior art, increase of service life prevents the hydro-cylinder oil leak, improves production efficiency.
The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a sharpening machine pushes away steel hydro-cylinder device, includes the hydro-cylinder and pushes away the steel crossbeam, the hydro-cylinder sets up on the support frame, in the hydro-cylinder piston rod tip was located and is pushed away the steel crossbeam and both contact surfaces are the sphere contact, push away fixed guide bar on the steel crossbeam, the guide bar is worn to locate in the support frame, and when the hydro-cylinder piston rod moved, the drive pushed away the steel crossbeam and pushes away to the steel billet, realizes the steel billet unloading.
The end parts of the piston rods of the oil cylinders are hooped in a pair of half shafts, the steel pushing cross beam is provided with a circular groove matched with the two half shafts, and the two half shafts are arranged in the circular groove.
Compared with the prior art, the utility model has the advantages of: the steel pushing oil cylinder device of the sharpening machine changes the contact surface of the end part of an oil cylinder piston rod and a steel pushing cross beam from plane contact to spherical contact, not only is the cost of transformation low, but also the phenomenon that oil leakage occurs when the oil cylinder is sealed and damaged or oil cylinder bolts are broken due to hard pushing is avoided, and the service life and the production efficiency of the oil cylinder are improved.
Drawings
FIG. 1 is a schematic view of a steel-pushing cylinder device of a sharpening machine according to an embodiment of the present invention;
FIG. 2 is an enlarged view of a half-cutting cylinder device of the sharpening machine according to an embodiment of the present invention;
in the figure, 1 guide rod, 2 oil cylinders, 3 support frames, 4 steel billets, 5 platforms, 6 steel pushing cross beams and 7 half are arranged.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the steel pushing cylinder device of the sharpening machine in the embodiment includes a cylinder 2 and a steel pushing beam 6, the cylinder 2 is disposed on a support frame 3, and the end of a piston rod of the cylinder 2 is hooped in a pair of half shafts 7, so that the surface of the end of the piston rod of the cylinder 2 is spherical. The steel pushing cross beam 6 is arranged at the front end of a piston rod of the oil cylinder 2, a circular groove is formed in the steel pushing cross beam 6, the end part of the piston rod of the oil cylinder 2 is placed in the circular groove, and the contact surface of the piston rod of the placed oil cylinder 2 and the steel pushing cross beam 6 is in spherical contact. Push away fixed 2 guide bars 1 on steel crossbeam 6, 2 guide bars 1 wear to establish in support frame 3, play the guide effect to pushing away steel crossbeam 6. When the piston rod of the oil cylinder 2 extends out, the steel pushing beam 6 is driven to move towards the steel billet 4 placed on the platform 5, and the steel billet 4 is pushed away from the platform 5, so that blanking of the steel billet 4 is realized.
The end face of the piston rod of the oil cylinder 2 is in spherical contact with the contact surface of the steel pushing cross beam 6, the end part of the piston rod of the oil cylinder 2 can be finely adjusted in the steel pushing cross beam 6, when the steel pushing cross beam 6 and the steel billet 4 are not in the central position, the stress balance of the piston rod of the oil cylinder 2 is ensured, the phenomenon that oil leakage occurs when the oil cylinder 2 is sealed and damaged or the oil cylinder bolt is broken due to hard pushing is avoided, and the service life and the production efficiency of the oil cylinder 2 are improved.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
