Abstract
The present invention relates to an electric heating type band saw welder, particularly to an electric heating welding machine used for repairing a band saw blade. An original electric heating type band saw welder mainly adopts two silicon carbide rods as an electric heating source, and thus, pressure resistance is lower than the traditionally used network voltage of 220V; moreover, because of the use of an autotransformer needs to be added for adjusting and reducing the resistance of the silicon carbide rods, the autotransformer occupies two thirds of the total cost. The electric heating type band saw welder is composed of a platform 1, a support 2 and a heating element, wherein the platform 1 is provided with pinch rollers; the support 2 is embedded in the platform 1; the heating element is arranged in the support 2 which is provided with a compressing handspike 21; the heating element comprises a refractory brick 3 and silicon carbide rods 4 arranged in the refractory brick 3, and a metal heat conducting plate 5 is arranged on a compressing surface among the silicon carbide rods 4. The product is used for welding fractures of band saw blades.
Description
Technical field:
The present invention relates to the electric heating electroplating equipment wielding machine that uses when a kind of saw blade is repaired.
Background technology:
Original hot type electric welding machine for band saw Elemas of two length 180mm that adopt as power supply more, because two Elemas are when normally generating heat to 1200-1300 ℃, single pressure drop is the 55-65 volt, is the 110-130 volt after two series connection, be lower than the 220v line voltage that tradition is used, need pressure regulation.And because the Elema resistance value raises after using a period of time, heating power reduces, and the auto-transformer that must add 5kw is adjusted, and auto-transformer accounts for about 2/3 of whole cost.
Summary of the invention:
The present invention will understand the technical problem of solution: a kind of hot type electric welding machine for band saw cheaply is provided.
The technical scheme that addresses the above problem:
Hot type electric welding machine for band saw, by the platform that pinch roller is housed, be set in the support in the described platform, and the heating member that is contained in the support is formed, be equipped with on the described support and compress thick stick, described heating member comprises refractory brick and the Elema that is contained in the described refractory brick, it is characterized in that: the stainless steel heat-conducting plate is housed on the stitching surface between the described Elema.
Above-mentioned hot type electric welding machine for band saw, polyphone connects between the described Elema, makes its dividing potential drop adapt to external voltage.
Above-mentioned hot type electric welding machine for band saw, series circuit one end of described Elema is equipped with the diode of halfwave rectifier, makes the dividing potential drop of each Elema adapt to external voltage.
Beneficial effect compared with prior art:
1. this product adopts the mode of many rod polyphones or diode polyphone, no longer requires to use auto-transformer, reduces separate unit cost 2/3, and cost is low.
2. the graphite guide plate in the existing product damages easily, has a strong impact on the service life of product, and this product adopts guide metal, as original graphite cakes of replacement such as corrosion resistant plates, reduces oxidation, improves working face intensity, the service life of having improved product.
3. simple in structure, volume is little, and the required heat that heats up is little, and heat radiation is few, and it is original about 2/3 that heating power is reduced to, good energy-conserving effect.
4. high efficiency is welded a band steel weld seam and is only needed 15 minutes, can satisfy and produce needs.
5. have artificial adjustment spiral thick stick and compress, the degree of compressing can freely be adjusted.

Embodiment 2:
Embodiment 1 described hot type electric welding machine for band saw, polyphone connects between the described Elema 4, makes its dividing potential drop adapt to external voltage.
Embodiment 3:
Embodiment 1 described hot type electric welding machine for band saw, series circuit one end of described Elema 4 is equipped with the halfwave rectifier diode, makes the dividing potential drop of each Elema adapt to external voltage.
Above-mentioned hot type electric welding machine for band saw, be connected in series between the described Elema 4, Elema is generally selected 4 65 watts just passable for use, the temperature of heating tube reaches 1150 when spending, temperature can reach the job requirement temperature of 950 degree in the stove, the withstand voltage of this moment is 260 volts, can use under the 220v common voltage.
Embodiment 4:
Above-mentioned hot type electric welding machine for band saw, an end of the series circuit of described Elema 4 is equipped with diode, carries out halfwave rectifier.
This product mainly is that the band saw fracture that uses in the woodenware process is welded, and specifically is the copper sheet that is clipped between fracture to be heated by heat-conducting plate with heating, and copper sheet is dissolved, and fracture is bonding.And product no longer needs to carry out self-coupling.
