Description
Technical field
The present invention relates to a kind of thermal treatment to be heated equalizing device, especially relate to and be heated evenly device in a kind of pick-like bit heat treatment process.
Background technology
At present, coal in China is produced and is mainly adopted Mechanical Crushing, and scene mainly adopts coalcutter, plough, and development machine 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, the problems such as cutter head comes off, cutter head is cracked, tool bit abrasion that cause pick easily to produce, reduce work-ing life, become the most fragile in coal production and measure maximum part with replacing.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 of coal production, but also can reduce production efficiency because changing the time increase of pick.At home in pick production technique, the method of the high Frequency Induction Heating of general employing is heat-treated pick, due to the automatization that pick is produced, make pick in heat treated process, the portions under heat near thermal source is larger, the portions under heat of stow away from heat is less, thus cause each side of pick to be heated inequality, make the thermal treatment of pick not reach expected effect, interior tissue is comparatively complicated, have impact on the thermal treatment quality of pick, reduce the work-ing life of pick.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of pick-like bit thermal treatment and to be heated equalizing device.By installing two taper roller bearings on firm banking, this device makes that the heat treatment process of pick in flow production line is proal realizes rotation simultaneously, the each position of pick 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 is heated equalizing device, comprise carrier bar, base, bolt, bearing, bearing, pick clamping device, axle sleeve, sleeve, snap ring, roller, base plate, rubber plate and iron angle, iron angle is provided with in the middle part of described base plate, described set square is covered with rubber plate and is connected with described set square by screw, described rubber plate and roller contact, position, described bearing axis is provided with pillar and is positioned at the bracing frame of described pillar side, base is provided with below described bearing, two bearings distributed up and down are provided with below described bearing, described two symmetrical carrier bars are fixed on below described base respectively by bolt.
Described pick clamping device comprises pillar and bracing frame.
Described bearing adopts axle sleeve and sleeve to fix, and described bearing lower contact is provided with snap ring, and described snap ring is fixed on described bearing, is convenient to the location of bearing, installation and dismounting.
Described pick clamping device peripheral hardware wearing layer.
Described pillar is more than three or three.
Be connected with described carrier bar by described bolt, under chaindriven effect, the base of pick clamping device is driven to travel forward, base is connected by bearing with bearing, due to base plate fix and base drive pick 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 be threaded to be connected with pillar and bearing, is convenient to the shape changing bracing frame like this, can processes, reduce tooling cost to polytype pick.Also can effectively repair bracing frame and pillar, the distortion overcoming pick bracing frame and pillar in heat treatment process is excessive, and causes the decline of working accuracy, improves working accuracy simultaneously.
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, thus cause frictional power, bearing is contacted by bearing with between base again, realizes the spinning motion of pick, makes being heated evenly of pick everywhere.
In such scheme, adopt axle sleeve and sleeve to carry out cooperation location between two bearings, be convenient to the location of bearing, installation and dismounting.
In such scheme, roller contacts with rubber plate, the frictional force of both utilizations thus drive pick to be rotated, and roller adopts with bearing and is threaded, and the heat treated speed of rotation of pick can be adjusted by the diameter of change roller.
In such scheme, rubber sheet is connected with iron angle by screw, and the position of rubber sheet by manually carrying out suitable adjustment, and can be changed, to adapt to the normal work of equipment timely.
Beneficial effect of the present invention is: compared with prior art, the invention has the advantages that and eliminates in traditional pick heat treatment process uneven problem of being heated, improve the thermal treatment quality of pick, extend the work-ing life of pick.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details.
Embodiment: as shown in Figure 1 and Figure 2, a kind of pick-like bit thermal treatment is heated equalizing device, 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 and pillar 7 are pick clamping devices 15, play the effect of fixing pick; Be provided with wearing layer 16 outside pick clamping device 15, prevent wearing and tearing from increasing work-ing life; Bearing 5 plays and drives pick travel forward with the effect of rotary motion 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 to be enclosed within bearing 5 and to carry out shrink-fit with base 2; Snap ring 10 is fixed on carrier bar 1 below bearing 4 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 by the position of rotating guide adjusting triangle iron the position regulating rubber plate 13; Roller 11 mainly plays a part to adjust rotating speed, is adjusted the speed of rotation of pick by the diameter changing roller 11.
Use the pick-like bit thermal treatment of the present embodiment to be heated equalizing device, carrier bar 1, under power-actuated effect, drives base to carry out the motion of translation circulated, thus realizes moving forward of pick; Meanwhile, because the roller 11 on bearing 5 contacts with the rubber plate 13 on iron angle 14, under the effect of frictional force huge on rubber plate 13, roller 11 is rotated, roller 11 drives bearing 5 to carry out circumferential motion, thus realizes the rotation of pick, and each position of pick is heated evenly.
When rubber plate 13 weares and teares excessive, and when the frictional force between roller 11 does not reach and requires, bearing 5 just can not realize rotary motion, we utilize rubber plate setting device like this, by regulating the length of guide rod thus promoting (retrogressing) iron angle 14, rubber plate 13 is engaged closely with roller 11, thus meets the requirement of the power that pushing rolling wheels rotates.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; do not departing from the prerequisite of spirit and scope of the invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent.
