Description

A kind of wheel of wheeled engineering machinery of welding not uniform thickness

Technical field

The utility model belongs to mechanism wheel technical field, and in particular to be a kind of welding not uniform thickness wheeled engineering Mechanical wheel, for wheeled engineering truck, alternative traditional spoke, wheel rim, the wheeled engineering of bcad seats three-member type Combination Welding Mechanical wheel, and there is higher intensity.

Background technology

The wheel of wheeled engineering machinery of three group welderings of tradition（As shown in Figure 1）Production technology and product exist in itself it is more Limitation, the spoke wheel rim of this kind of wheel divide respectively from two kinds of different raw material, and by process routes such as clamping, positioning Do not make, finally assemble and be welded, manufacture production is divided into three spoke, wheel rim and assembly production lines, and technique is cumbersome, management Complexity, and the production environment for being related to welding is more severe, spark, splashing, dust etc. be present；In addition, the hot rolling of inner rim portion, weldering Connect and polish existing defects, and the link of assembly soldering has difficult point, after multiple assembly welding so that product is unable to reach more High accuracy；When driving, rupture easily is produced from wheel rim position while welding and spoke rim position while welding during wheel stress, causes traffic The hidden model of safety.

As shown in figure 1, the wheel of wheeled engineering machinery 1 of traditional three unit-weldeds is by traditional wheel rim cylinder 101, traditional tyre bead Seat 102 and the Combination Welding of traditional spoke 103 form.

The shaping of traditional wheel rim cylinder 101 is to carry out edge rolling and the butt welding at docking port using the flat board of certain length, should Secondary welding forms traditional wheel rim cylinder counterpart weld seam 104；Traditional wheel rim cylinder counterpart weld seam 104 is handled afterwards, then passed through Cross the techniques such as enlarging, shaping and form wheel rim cylinder, therefore have one of Welder in traditional wheel rim cylinder 101 separately formed stage Sequence, torn in enlarging and reforming process easily at traditional weld bond of wheel rim cylinder counterpart weld seam 104.

The profiled outline of traditional bcad seats 102 is then formed by steel plate rolling, carries out edge rolling and butt welding, this butt welding shape afterwards There is one of welding sequence again into traditional bcad seats counterpart weld seam 106, therefore in traditional bcad seats 102 separately formed stage.

Traditional spoke 103 is formed by hydraulic press blanking and turning.

Traditional wheel rim cylinder 101 carries out soldering, this time with traditional bcad seats 102 after rolling in whole circumference direction first Soldering forms traditional wheel rim cylinder and bcad seats circumferential weld 105, forms the wheel rim body of wheel, handled after weld seam again with biography Steerage spoke 103 carries out soldering, and this soldering forms traditional bcad seats and spoke circumferential weld 107；Therefore in the assembling soldering stage Shared twice welding sequence, during the use of wheel, traditional wheel rim cylinder and bcad seats circumferential weld 105 and traditional tyre bead Seat due to existing defects, can not bear a certain degree of circulation impact stress with the welding position of spoke circumferential weld 107, easily from Traditional wheel rim cylinder starts to split with bcad seats circumferential weld 105 and traditional bcad seats and the commissure of spoke circumferential weld 107 Trace, even it is kept completely separate when serious.

Four welding sequences are shared in the forming process of the wheel of wheeled engineering machinery 1 of traditional three unit-weldeds.

The content of the invention

The purpose of this utility model is the deficiency and defect for existing product, there is provided one kind is based on existing product installation chi Very little welding, not uniform thickness, high intensity, high accuracy, the wheel of wheeled engineering machinery for being easy to implement automated production.

The utility model is achieved through the following technical solutions：A kind of industrial wheeled equipment car of welding not uniform thickness Wheel, is made up of, described wheel body is a kind of overall structure shape without any weld mark wheel body；And the wheel Body is that same material is made of one piece；The wheel body includes welding wheel rim cylinder, in the welding wheel rim cylinder Outer ring set one circle welding bcad seats and at the end surfaces of the welding bcad seats set welding spoke.

The utility model uses one block of cake steel plate as blank, based on spinning, forging and stamping supplemented by moulding process one into Type forms.

The utility model have the beneficial effect that in：1st, this wheel passes through the multiple working procedure final molding based on spinning, Automated production is easy to implement, and machining accuracy is higher；2nd, spoke and wheel rim are same blank material rotary press modelling, without any Fit engagement face, sealing wire and fill solder thing, its fine and closely woven, intensity enhancing of tissue；3rd, not uniform thickness change integrally can be achieved in this wheel Section is molded, so as to reinforcement weak part, it is appropriate reduce that stress is small or material without force part, realize the light of wheel Quantify；4th, welding link, can solve the welding difficulty of high strength steel, there is no hot rolling, welding and polishing defect；5th, nothing Three traditional spoke, wheel rim and assembly production lines are integrated into a production line by the production line for welding not uniform thickness, are realized Continuous productive process is automated, simplifies technique, simplifies management；6th, welding link has been abandoned, has eliminated spark, dust caused by welding The problem of Deng polluting, while rupture being also easy to produce in the absence of wheel rim position while welding and spoke rim position while welding, greatly reduce traffic peace Full hidden danger.
