Technical field
The utility model relates to a kind of thermal treatment equalizing device that is heated, and especially relates to the device that is heated evenly in a kind of pick-like bit heat treatment process.
Background technology
At present, coal in China is produced the main Mechanical Crushing that adopts, the on-the-spot main coalcutter that adopts, and plough, development machines etc. are exploited.Pick is the vitals of coal winning machinery working mechanism, pick is in the process of mining, operating mode is severe, bear higher stress, shear-stress and impact load, cause pick easily to produce the problems such as cutter head comes off, cutter head is cracked, tool bit abrasion, reduced work-ing life, become the most fragile and replacing in coal production and measure maximum part.The quality of pick quality and performance directly affects throughput and the working efficiency in colliery, in the process of coal production, a large amount of pick consumption not only increases cost of ton coal, affects the economic benefit that coal is produced, but also can reduce production efficiency because changing the time increase of pick.At home in pick production technique, the general method of high Frequency Induction Heating that adopts is heat-treated pick, automatization because pick is produced, makes pick in heat treated process, near the part of thermal source, is heated larger, the part of stow away from heat is heated less, the inequality thereby the each side that causes pick is heated, makes the thermal treatment of pick not reach expected effect, and interior tissue is comparatively complicated, affect the thermal treatment quality of pick, reduced the work-ing life of pick.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of pick-like bit thermal treatment equalizing device that is heated.This device makes by two taper roller bearings are installed on firm banking that the heat treatment process of pick in flow production line is proal realizes rotation simultaneously, pick each position in heat treated process is heated and reaches balanced, improve the internal organizational structure of pick, improve the thermal treatment quality of pick, strengthen the work-ing life of pick.
A kind of pick-like bit thermal treatment equalizing device that is heated, comprise carrier bar, base, bolt, bearing, bearing, pick clamping device, axle sleeve, sleeve, snap ring, roller, base plate, rubber plate and iron angle, described base plate middle part is provided with iron angle, described set square is covered with rubber plate and is connected with described set square by screw, described rubber plate and roller contact, the bracing frame that position, described bearing axis is provided with pillar and is positioned at described pillar one side, described bearing below is provided with base, described bearing below is provided with two bearings that distribute up and down, described two symmetrical carrier bars are secured by bolts in respectively described base below.
Described pick clamping device comprises pillar and bracing frame.
Described bearing adopts axle sleeve and sleeve to fix, and the below contact of described bearing is provided with snap ring, and described snap ring is fixed on described bearing, is convenient to location, installation and the dismounting of bearing.
Described pick clamping device peripheral hardware wearing layer.
Described pillar is more than three or three.
By described bolt, be connected with described carrier bar, under chaindriven effect, drive the base of pick clamping device to travel forward, base is connected by bearing with bearing, because base plate is fixed and base drives pick in the proal while, under the effect of taper roller bearing, realize the rotation of pick self, make being heated evenly of pick everywhere, improve the thermal treatment quality of pick.
In such scheme, bracing frame adopts the mode being threaded to be connected with pillar and bearing, is convenient to like this change the shape of bracing frame, can process polytype pick, has reduced tooling cost.Simultaneously also can effectively to bracing frame and pillar, repair, overcome pick distortion of bracing frame and pillar in heat treatment process excessive, and cause the decline of working accuracy, improve working accuracy.
In such scheme, carrier bar is connected with base by bolt, and chain, under the drive of sprocket wheel, drives base to carry out translational motion.Meanwhile, because bearing contacts with base plate, thereby cause frictional power, bearing contacts by bearing again with between base, realizes the spinning motion of pick, makes being heated evenly of pick everywhere.
In such scheme, between two bearings, adopt axle sleeve and sleeve to coordinate location, be convenient to location, installation and the dismounting of bearing.
In such scheme, roller contacts with rubber plate, thereby utilizes both frictional force to drive pick to be rotated, and roller adopts and is threaded with bearing, and the heat treated speed of rotation of pick can be adjusted by changing the diameter of roller.
In such scheme, rubber sheet is connected with iron angle by screw, and the position of rubber sheet can be by manually carrying out suitable adjustment, and can change timely, to adapt to the normal operation of equipment.
The beneficial effects of the utility model are: compared with prior art, the utility model has the advantage of and eliminated the uneven problem of being heated in traditional pick heat treatment process, improved the thermal treatment quality of pick, extended the work-ing life of pick.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details.
Embodiment: as shown in Figure 1 and Figure 2, the thermal treatment equalizing device that is heated, comprises carrier bar 1, base 2, bolt 3, bearing 4, bearing 5, bracing frame 6, pillar 7, axle sleeve 8, sleeve 9, snap ring 10, roller 11, base plate 12, rubber plate 13 and iron angle 14.Bracing frame 6 is pick clamping devices 15 with pillar 7, plays the fixedly effect of pick; The outer wearing layer 16 that is provided with of pick clamping device 15, wear prevention increases work-ing life; Bearing 5 plays and drives the effect that pick travels forward and rotatablely move and contact with the rubber plate 13 on base plate 12; Axle sleeve 8 and sleeve 9, between two bearings, play the role of positioning; Bearing 4 is enclosed within on bearing 5 and with base 2 and carries out shrink-fit; Snap ring 10 is fixed on bearing 4 below carrier bars 1 and is fixed on chain by chain connector, and is connected with base 2 by bolt 3; Rubber plate 13 is fixed on iron angle, mainly plays increasing friction force, and iron angle 14 utilizes groove to be stuck on base plate 12, realizes the position that regulates rubber plate 13 by the position of rotating guide adjusting triangle iron; Roller 11 mainly works to adjust rotating speed, adjusts the speed of rotation of pick by changing the diameter of roller 11.
Use the pick-like bit thermal treatment of the present embodiment equalizing device that is heated, carrier bar 1 under power-actuated effect, the motion of translation that drives base to circulate, thus realize moving forward of pick; Meanwhile, because the roller 11 on bearing 5 contacts with the rubber plate 13 on iron angle 14, on rubber plate 13 under the effect of huge frictional force, roller 11 is rotated, roller 11 drives bearing 5 to carry out circumferential motion, thereby realizes the rotation of pick, and each position of pick is heated evenly.
When rubber plate 13 weares and teares excessive, and the frictional force between roller 11 does not reach while requiring, bearing 5 just can not be realized and rotatablely moving, we utilize rubber plate setting device like this, thereby by regulating the length of guide rod to promote (retreating) iron angle 14, rubber plate 13 is engaged closely with roller 11, thereby meet the requirement of the power of pushing rolling wheels rotation.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; in the prerequisite that does not depart from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent.
