DETAILED DESCRIPTION

[0019] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0020] Please see attached Figure 1-3As shown, a device for correcting the side bending of an arc-shaped cutting edge comprises molds symmetrically arranged for fixing the two ends of the arc-shaped cutting edge 12 and a correction mechanism arranged in the side bending direction of the arc-shaped cutting edge 12, wherein the structure of the arc-shaped cutting edge 12 is as shown in the attached Figure 1 As shown, the arc-shaped scraping edge 12 is easily bent sideways into the arc-shaped dotted line state in the figure after heat treatment, and the mold includes an upper die 2 and a lower die 3, wherein the upper die 2 and the lower die 3 are provided with a contour cavity matching the shape of the arc-shaped scraping edge 12, and the upper die 2 and the lower die 3 are connected by a plurality of positioning pins 10, and the two ends of the arc-shaped scraping edge 12 are respectively placed in the contour cavity and pressed by the cooperation of the upper die 2 and the lower die 3, and then fixed by the positioning pins 10;

[0021] As attached Figure 4 As shown, the correction mechanism includes a fixed block 4, a slide rail 5 and a movable block 6 that moves along the slide rail 5. The slide rail 5 is arranged along the side bending direction of the arc-shaped shovel blade 12, that is, the direction of the slide rail 5 is perpendicular to the length direction of the arc-shaped shovel blade 12. Preferably, the slide rail 5 is a slide groove composed of two symmetrically arranged sliders 51, and the front end of the movable block 6 is provided with a top block 61 that matches the bucket tooth spacing on the arc-shaped shovel blade 12, and the bottom of the top block 61 moves in the slide groove. Through the two sliders 51, the top block 61 can only move along the length direction of the slide groove to prevent the top block 61 from shifting. A push rod 7 for pushing the movable block 6 to move along the slide rail 5 is provided on the movable block 6 and the fixed block 4.

[0022] In the above embodiments, preferably, as shown in the attached Figure 4 As shown, the push rod 7 includes a hinged connecting rod 1 71 and a connecting rod 2 72, and one end of the connecting rod 1 71 and the connecting rod 2 72 are respectively hinged to the top of the movable block 6 and the fixed block 4, so that when the connection between the connecting rod 1 71 and the connecting rod 2 72 is pressed downward, the movable block 6 is pushed to move along the slide rail 5 toward the arc-shaped scraper edge 12, and a pressure ring 73 is coaxially arranged at the hinge of the connecting rod 1 71 and the connecting rod 2 72. Specifically, the side of the arc-shaped shovel blade 12 with the bucket teeth is placed toward the side of the correction mechanism and fixed by the upper die 2 and the lower die 3, and then the hydraulic press is moved downward to press on the pressure ring 73 to prevent the hydraulic press from directly pressing on the push rod 7 and causing damage to the device. Since the connecting rod 1 71 and the connecting rod 2 72 are hinged, and the fixed block 4 is fixed, the connecting rod 1 71 extends to the side away from the fixed block 4, thereby driving the movable block 6 and the top block 61 to move. The top block 61 gradually abuts against the gap between the bucket teeth of the arc-shaped shovel blade 12, and gradually pushes the side bending part to move in the opposite direction of the side bending to complete the correction. The operation is simple and manpower is saved.

[0023] The side bending correction device also includes a base 1, and the fixed block 4 and the slide rail 5 are fixed on the base 1. Because the two ends of the arc-shaped scraping edge 12 are fixed, when the top block 61 is corrected, the arc-shaped scraping edge 12 is fixed and has no movable distance, so it is easy to cause other deformations besides correction. Therefore, a positioning shaft 11 extending into the base 1 is fixed at the bottom of the lower die 3, and an movable hole (not shown in the accompanying drawings) that cooperates with the positioning shaft 11 is provided in the base 1. The positioning shaft 11 can rotate in the movable hole. When the two ends of the arc-shaped scraping edge 12 are fixed, when the top block 61 is corrected, the arc-shaped scraping edge 12 will be slightly diffused toward the two ends by the force, thereby driving the molds on both sides to rotate slightly, reducing deformation besides correction, as shown in the attached figure. Figure 1 The direction of rotation is shown by the arrow in the figure.

[0024] In the above embodiment, preferably, the correction mechanism further includes an elastic member 8 for connecting the movable block 6 and the fixed block 4, and the elastic member 8 is a reset spring; specifically, after pushing the movable block 6 and the top block 61 to correct the lateral bending, the hydraulic press moves upward, and the movable block 6 automatically retreats to the initial position under the action of the reset spring, without the need for manual reset, thereby improving the work efficiency and the automation of the device. At the same time, the correction mechanism further includes a limit pin 9 fixed on the movable block 6, and the limit pin 9 is set toward the fixed block 4. When one end of the limit pin 9 abuts against the fixed block 4, the movable block 6 stops retreating.

[0025] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0026] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
