Description
Technical Field
The utility model relates to a quenching heat treatment clamping device of scraper blade belongs to instrument heat treatment processing technology field in the pit.
Background
A scraper blade of a part of a scraper of a downhole casing cleaning tool is a plate-shaped special-shaped piece, the outer surface of the scraper blade is provided with square threads, the scraper blade is required to be high-hardness and wear-resistant, a matrix keeps certain obdurability, the size difference in the length direction and the height direction is large, and the wall thickness size difference of the whole structure is large. The heat treatment process comprises the steps of carburizing, quenching and tempering in a salt bath furnace, binding the scraper blade with iron wires during quenching, suspending the scraper blade on a simple cross tool, suspending the cross tool on a crane, and immersing the scraper blade in the salt bath furnace for quenching and heating. The scraper blade subjected to heat treatment in the furnace charging mode generates bending deformation along the length direction, so that the scraper blade cannot be assembled and fails, and the crane is positioned above the salt bath furnace at high temperature (more than or equal to 800 ℃) for a long time and is easily damaged.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the invention provides the clamping device for quenching heat treatment of the scraper blade, which has a simple structure, is easy to operate, is safe and reliable, and is used for reducing the heat treatment deformation of the scraper blade, ensuring the quality of the scraper blade and prolonging the service life of a crane.
The technical scheme of the utility model: the utility model provides a quenching heat treatment clamping device of scraper blade, includes U-shaped support frame I and U-shaped support frame II, be in the same place through fixing bolt hinged joint between U-shaped support frame I and the U-shaped support frame II, constitute "X" shape movable support, be provided with the supporting seat at the lower part both ends of "X" shape movable support symmetrically, seted up the through-hole on the supporting seat, penetrated the vaulting pole in the through-hole, there is the tip screw at the both ends threaded connection of vaulting pole.
Furthermore, a group of baffle rings are sleeved on the support rod.
Further, rings are symmetrically welded on the top of the X-shaped movable support.
Due to the adoption of the technical scheme, the utility model has the advantages of: the utility model discloses effectively solve the bending deformation problem when scraper blade thermal treatment, strictly guaranteed heat treatment quality, improved the assembly qualification rate of sleeve pipe burnisher in the pit. The device clamping is convenient, simple structure, easily operation, and safe and reliable can not occupy the crane for a long time, has reduced the corruption of salt bath stove fused salt to the crane, improves production efficiency, extension crane life. Furthermore, the utility model discloses can carry out the multilayer clamping according to the size of salt bath stove, also can be used to other types of stoves like protective atmosphere stove etc. easily realize mass production.

Description of the reference numerals: 1-stay bar, 2-end screw, 3-baffle ring, 4-U-shaped support frame I, 5-hoisting ring, 6-U-shaped support frame II, 7-support seat, 8-fixing bolt and 9-scraper blade.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail with reference to the accompanying drawings and embodiments.
The embodiment of the utility model provides a: referring to fig. 1-3, the utility model discloses a quenching heat treatment clamping device of scraper blade, including U-shaped support frame I4 and U-shaped support frame II 6, together through 8 hinged joint of fixing bolt between U-shaped support frame I4 and the U-shaped support frame II 6, constitute "X" shape movable support, be provided with supporting seat 7 at the lower part both ends of "X" shape movable support symmetrically, seted up the through-hole on supporting seat 7, penetrated vaulting pole 1 in the through-hole, there is tip screw 2 at vaulting pole 1's both ends threaded connection. A group of baffle rings 3 are sleeved on the support rod 1. The top of the X-shaped movable support is symmetrically welded with hanging rings 5.
The utility model discloses a theory of operation:
the clamping device is placed on a charging platform, the scraper blade 9 is penetrated onto two supporting rods 1 corresponding to the lower part of the X-shaped movable support by using holes at two ends of the scraper blade 9, and the scraper blade 9 is separated by placing the baffle ring 3 between the scraper blades 9, so that a certain gap is formed between the scraper blades 9, the heating and cooling effects are prevented from being influenced, and the heat treatment quality is strictly ensured. In order to maintain balance, the number of scraper blades 9 before and after the stay bar 1 is the same, i.e. 4 scraper blades at each end of the stay bar 1. After the scraper blade 9 is installed, the upper end part screws 2 are installed at two ends of the two support rods 1, the crane hooks the hanging ring 5 to lift the scraper blade 9 to dip into the salt bath furnace, the U-shaped support frame I4 and the U-shaped support frame II 6 are placed on a furnace body at a furnace mouth of the salt bath furnace, and the crane moves away. U-shaped support frame I4 and U-shaped support frame II 6 receive scraper blade 9 and the effect of self gravity, to the effort that two vaulting poles 1 had outwards to drag, produce certain restraint to scraper blade 9 because the bending that self structure leads to reduce the bending deformation of scraper blade 9.
