Description

Technical Field

[0001] This utility model belongs to the field of bucket processing technology, specifically relating to a heat treatment device for excavator buckets after welding. Background Technology

[0002] As a core piece of construction machinery, the performance of the excavator's bucket directly affects construction efficiency and reliability. Welding, a key process in bucket manufacturing, can lead to structural deformation, reduced fatigue life, and even cracking failure due to residual stress after welding. Therefore, post-weld heat treatment is a necessary step to eliminate stress, improve microstructure, and enhance overall performance.

[0003] Traditional box furnaces use single-sided heating or natural convection. As the workpieces are large, irregularly shaped components, the furnace bucket is prone to excessive temperature gradients, leading to incomplete stress relief and affecting material stability. Traditional overhead crane hoisting methods require manual alignment, which is time-consuming and prone to large positioning errors, easily causing workpiece collisions and deformation, impacting production cycle and product quality.

[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a post-weld heat treatment device for excavator buckets, comprising:

[0027] The heat treatment assembly 100 includes a base 101, a bracket 102 fixedly connected to the side wall of the base 101, a housing 103 fixedly connected to the side wall of the bracket 102, a heat treatment host 104 encapsulated inside the housing 103, and a door 105 hinged to the side wall of the housing 103.

[0028] The feeding assembly 200 includes a track 201 fixedly connected to the side wall of the base 101, a track carriage 202 adapted to be installed on the side wall of the track 201, a pad 203 inserted into the upper end of the track carriage 202, and a sealing plate 204 installed on the upper end of the pad 203. The side wall of the sealing plate 204 is used in conjunction with the bottom opening of the box 103.

[0029] The excavator bucket post-weld heat treatment equipment adopts a modular design, mainly consisting of a heat treatment component 100 and a feeding component 200. The heat treatment component 100 is vertically fixed to one side of the base 101 via a bracket 102, forming a stable heat treatment station. The feeding component 200 is arranged along the length of the base 101, with its track 201 extending to the outside of the bracket 102, connecting external feeding and internal processing of the bucket. The base 101 serves as the equipment foundation, ensuring it can withstand vibrations and loads during the heat treatment process. The bracket 102 is connected to the base 101 via a full penetration weld, providing rigid support for the housing 103. The housing 103 adopts a double-layer jacket structure, with an inner layer of high-temperature resistant stainless steel plate and an outer layer of carbon steel protective shell, filled with an aluminum silicate fiber cotton insulation layer to effectively reduce heat loss. The heat treatment host 104 integrates an electric heating tube array, a circulating fan, and a temperature sensor, achieving temperature control through a control system to perform heat treatment on the bucket. Door 105 is used to enclose chamber 103, maintaining a stable heat treatment environment. Rail 201 is used to move the railcar 202, facilitating the loading of heat-treated components. A liftable pad 203 mounted on the upper end of the railcar 202 is used to install a sealing plate 204. The sealing plate 204 is a circular heat-resistant steel plate with beveled sealing edges, forming a seal with the bottom opening of chamber 103 to reduce heat leakage. This facilitates heat treatment of materials placed on the sealing plate 204.

[0030] Specifically, the feeding assembly 200 also includes a support rod 205 hinged to the side wall of the railcar 202, and a connecting rod 206 hinged to the end of the support rod 205, with the end of the connecting rod 206 hinged to the lower side wall of the pad 203.

[0031] Among them, the support rod 205 and the connecting rod 206 form a parallelogram mechanism, which is made of high-strength alloy steel pipe. Both ends are connected to the railcar 202 and the pad 203 through spherical bearings to realize the smooth lifting and lowering of the pad 203.

[0032] Furthermore, a shaft 207 is rotatably installed at the connection between the support rod 205 and the connecting rod 206. The support rod 205 and the connecting rod 206 are symmetrically installed at both ends of the shaft 207. An adjusting seat 208 is rotatably installed in the middle of the shaft 207. A double-ended lead screw 209 is threadedly connected to the middle of one set of adjusting seats 208, and another set of adjusting seats 208 is threadedly connected to the other end of the double-ended lead screw 209. A handle 210 is fixedly connected to the end of the double-ended lead screw 209, and the handle 210 extends to the outside of the railcar 202.

[0033] The adjusting seat 208 is clamped to the shaft 207 by bolts. The double-ended lead screw 209 and the handle 210 have opposite threads at both ends. By rotating the handle 210, the two sets of adjusting seats 208 are driven to move towards or away from each other, thereby adjusting the angle of the support rod 205.

[0034] It should be noted that the side wall of the railcar 202 is rotatably mounted with rollers that cooperate with the rail 201, and the end of the rail 201 extends to the outside of the support 102. The feeding assembly 200 also includes a transfer frame 211 fixedly connected in the middle of the support 102, and an auxiliary car 212 adapted to be installed in the middle of the rail 201. The auxiliary car 212 and the transfer frame 211 are used in conjunction with the railcar 202.

[0035] Among them, the adapter frame 211 and the auxiliary vehicle 212 are L-shaped steel structures with transition guide rails on the top; the auxiliary vehicle 212 has a similar structure to the railcar 202, but the lifting mechanism is eliminated, and it is used for intermediate transfer of the machine bucket to improve the equipment utilization rate.

[0036] During use, in the loading stage: the railcar 202 moves along the rail 201 to the loading position outside the support 102, and the handle 210 is rotated to drive the adjusting seat 208 to move via the double-headed lead screw 209. The pad 203 is lowered to its lowest position through the parallelogram mechanism formed by the support rod 205 and the connecting rod 206. The overhead crane lifts the welded bucket onto the pad 203, and precise positioning is achieved through the positioning pin hole and the positioning boss at the bottom of the bucket.

[0037] Feeding stage: The railcar 202 carries the bucket along the rail 201 toward the box 103, while rotating the handle 210 to raise the pad 203 until the sealing plate 204 is tightly fitted with the bottom opening of the box 103 to form a sealed space.

[0038] Heat treatment stage: Close door 105, start heat treatment host 104, electric heating tubes heat up to the set temperature, circulating fan forces hot air convection inside the chamber to ensure uniform temperature in all parts of the chamber. Temperature sensor monitors temperature data in real time and feeds it back to the control system for adjustment to ensure precise execution of the heat treatment process.

[0039] Unloading stage: After heat treatment, the railcar 202 exits the box 103, the pad 203 is lowered to the lowest position, and the crane lifts the treated bucket away from the equipment.

[0040] In summary, the beveled sealing design of the sealing plate 204 and the bottom opening of the housing 103, combined with the lifting and adjusting mechanism of the pad 203, effectively reduces heat leakage. The engagement of the positioning pin holes on the pad 203 with the positioning bosses at the bottom of the bucket, along with the guide rail system of the railcar 202, ensures the positioning accuracy of the bucket and improves the stability of heat treatment quality. The separate structure of the heat treatment components and the feeding components facilitates the transportation, installation, and maintenance of the equipment, and the layout can be flexibly adjusted according to production needs. The parallelogram linkage mechanism, combined with the double-headed screw adjustment, keeps the pad 203 horizontal during lifting and lowering, avoiding safety hazards caused by bucket tilting. The adapter frame 211 and the auxiliary car 212 enable the coordinated operation of multiple devices, adapting to the heat treatment requirements of buckets of different specifications and improving the flexibility of the production line.
