Description
Technical field
The utility model relates to the device that is used for clamping steel billet to be welded in a kind of endless rolling bonding machine, belongs to the metalworking technology field.
Background technology
The endless rolling bonding machine is being used for adjacent two equipment that rolled piece welds together of using when carrying out endless rolling of metallurgy industry.During the work of endless rolling bonding machine, at first utilize adjacent two rolled pieces of its steel billet clamping device clamping, make their relative position stable, utilize big electric current between two rolled pieces, to produce the flash of light high-temperature electric arc then, the rolled piece end face is dissolved the back upset, two rolled pieces are connected as a single entity, with the requirement of satisfying the different scale products of user and reduce the impact of steel part rolling equipment, also can reduce the cutting head cutting tail loss simultaneously, improve lumber recovery.
The steel billet clamping device of existing endless rolling bonding machine generally is made up of last clamping device and following clamping device, wherein, last clamping device generally comprises two vertical clamping limbs, the upper end of clamping limb links to each other with the piston rod that drives hydraulic cylinder, the lower end of each clamping limb is fixed with a clamping head that is connected with electrode welder, is provided with insulating materials between clamping head and the clamping limb.Because clamping device is in hot environment in welding process, the insulating materials between clamping head and the clamping limb is easy to be destroyed, and when serious even can come off, greatly reduces the reliability of clamping device, has shortened the service life of clamping device.In addition, the welding slag that splashes is easy to paste on the clamping limb, causes decreasing insulating, and the very difficult cleaning of this welding slag, has had a strong impact on normally carrying out of producing, and has reduced the operating efficiency of endless rolling.Adopt high temperature resistant exhausted gorgeous material and prevent that welding slag from pasting the bonding machine on the clamping limb though also have in the market, this bonding machine complex structure, cost is higher, and the user is difficult to accept.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of endless rolling bonding machine steel billet clamping device of simple in structure, with low cost and dependable performance is provided.
Problem described in the utility model realizes with following technical proposals:
A kind of endless rolling bonding machine steel billet clamping device, form by last clamping device and following clamping device, wherein, last clamping device comprises support and two vertical clamping limbs that are slidingly connected by clamping limb sliding sleeve and support, the upper end of each clamping limb drives hydraulic cylinder by one and is connected with support, the lower end is fixed with a clamping head that is electrically connected with electrode welder, be provided with insulation board between clamping head and the clamping limb, after the improvement, between two clamping limbs, be provided with cooling device, described cooling device is made of cooling water pipe and a plurality of cooling water nozzle, described cooling water pipe is fixed on the support and with the external refrigeration water source and links to each other, described cooling water nozzle is distributed on the cooling water pipe, and its spout is towards clamping limb.
Above-mentioned endless rolling bonding machine steel billet clamping device, end periphery is provided with insulation anticreep backplate under the described clamping limb, and described insulation anticreep backplate covers on the lapping defect of clamping limb and insulation board and with clamping limb fixedlys connected.
The utility model has been set up cooling device and insulation anticreep backplate on the basis of traditional endless rolling bonding machine steel billet clamping device, cooling device can spray cooling water to clamping limb in welding process, prevent that insulation board Yin Wendu is too high and damage, simultaneously welding slag can not be pasted on the clamping limb.Insulation anticreep backplate is used to stop insulation board to come off, and guarantees insulation effect.
The utility model is not only simple in structure, with low cost, and insulating materials is not fragile, has the reliability height, advantages such as long service life.Simultaneously, this device has also reduced the labour intensity that the worker clears up welding slag, has improved the operating efficiency of endless rolling bonding machine.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Each label is among the figure: 1, clamping limb; 2, cooling water pipe; 3, cooling water nozzle; 4, insulation board; 5, connecting plate; 6, clamping head; 7, hydraulic cylinder; 8, insulation anticreep backplate; 9, support; 10, clamping limb sliding sleeve; 11, steel billet; 12, following clamping device.
The specific embodiment
Referring to Fig. 1, the utility model comprises clamping device and following clamping device, and last clamping device mainly is made up of support 9, clamping limb 1, hydraulic cylinder 7, clamping limb sliding sleeve 10, insulation board 4, clamping head 6, insulation anticreep backplate 8, cooling water pipe 2 and cooling water nozzle 3.Connecting plate 5 among the figure is used to realize being electrically connected between clamping head 6 and the electrode welder between insulation board 4 and clamping head 6.
Clamping limb 1 can slide up and down in clamping limb sliding sleeve 10, and clamping limb 1 is connected with hydraulic cylinder 7, and flexible drive clamping limb 1, insulation board 4, connecting plate 5, the clamping head 6 of the piston rod by hydraulic cylinder 7 move up and down, thereby reaches the clamping of steel billet 11 and unclamp.Hydraulic cylinder 7 and cooling water pipe 2 all are fixed on the support 9 of endless rolling bonding machine (cooling water pipe 2 is connected with support 9 by clamping limb sliding sleeve 10 among Fig. 1).Clamping head 6 is a copper spare, and clamping head 6, connecting plate 5, insulation board 4, clamping limb 1 are bolted to connection; Insulation board 4 is between connecting plate 5 and clamping limb 1, by the insulation between insulation board 4 realization clamping heads 6 and the clamping limb 1.Insulation anticreep backplate 8 is by being bolted on the clamping limb 1, and it presses insulation board 4, insulation board 4 is carried out spacing, has eliminated insulation board 4 insulation values that causes that drops and has reduced problem.Cooling water pipe 2 links to each other with external water source, and cooling water nozzle 3 is installed on the cooling water pipe 2, and cooling water is sprayed on the clamping limb 1 by cooling water pipe 2 and cooling water nozzle 3, prevents that welding slag from high temperature pasting on the clamping limb 1.
