Description

Technical Field

[0001] The utility model belongs to the technical field of cone crusher cone processing equipment, and particularly relates to a mechanical hammering device used for hardening treatment of the cone working surface of the cone crusher. Background Art

[0002] Cone crushers are core equipment in the mining and construction industries. The wear resistance of their cone working surface directly determines the equipment's lifespan and crushing efficiency. Hammer hardening is a common process used in the industry. This process uses repeated impacts to plastically deform the surface metal, forming a hardened layer to improve wear resistance.

[0003] At present, hammer hardening mainly relies on manual operation, which has significant disadvantages: first, the quality is uneven, and the force, frequency and angle of manual hammering are difficult to unify, and local underhardening or overhardening is prone to occur, affecting the balanced force on the cone; second, the efficiency is low, and a skilled worker can only complete 1-2 small and medium-sized cones in a single day. Large cones with a diameter of more than 1.5m require 2-3 people to cooperate, which is difficult to meet the needs of large-scale production; third, the labor intensity is high and the safety risks are high. During operation, the vibration is severe and the noise exceeds 110 decibels, which can easily cause occupational diseases. The reaction force of the tool may also cause accidents of slipping out of the hand; fourth, it relies on operating skills. Novices need 3-6 months of training before they can take up their posts, and the processing quality varies greatly among workers, making standardization difficult; fifth, the adaptability is poor. The cones are mostly conical or stepped cones. It is difficult to accurately control the hammering point manually, and the curved transition area is prone to missed or repeated hammering.

[0004] The few existing mechanical hammering devices have simple structures and limited adjustment flexibility: some can only hammer in a single direction and cannot adapt to the curvature of the cone surface; some can adjust the angle, but the operation is cumbersome, and the hammering parameters are fixed, making it difficult to adapt to cones of different materials and thicknesses. Therefore, developing a semi-automated hammering device that combines manual adjustment with automated control to achieve uniform hammering and adapt to cones of different sizes has become the key to solving these existing pain points.

[0078] (2) Working principle and operation steps

[0079] 1. Working Principle

[0080] This equipment achieves hardening of the working surface of the cone (moving cone 60 or fixed cone 70) through the coordinated action of the cone rotating mechanism 10, hammer arm driving mechanism 20, turntable 30, telescopic arm 40 and air hammer 50:

[0081] The cone rotating mechanism 10 drives the cone to rotate at a constant speed, ensuring that each area of ​​the working surface is hit in sequence;

[0082] The hammer arm drive mechanism 20 adjusts the height and horizontal position of the air hammer 50, and the turntable adjusts the tilt angle of the telescopic arm 40 so that the hammer head of the air hammer 50 fits in with the working surface of the cone;

[0083] The telescopic arm 40 controls the displacement of the air hammer 50 in a fully manual or semi-automatic mode, and cooperates with the cone rotation to achieve full coverage hammering of the working surface;

[0084] In the fully manual mode, the displacement of the air hammer 50 is controlled by the manually operated telescopic hand wheel; in the semi-automatic mode, the displacement of the air hammer 50 is controlled by the microprocessor (STM32F103ZET6 single chip microcomputer) according to the preset logic (the pallet is extended and retracted 2-3cm after 1-3 turns), and it stops automatically after triggering the telescopic travel switch 45.

[0085] 2. Operation steps

[0086] (1) Preliminary preparation

[0087] ① Cone installation: Hoist the cone to be processed (moving cone 60 or fixed cone 70) to the center of the pallet 11, rotate the tightening screw 134 of each tightening assembly 13, and push the movable block 133 to move radially to clamp the cone, ensuring that the cone is concentric with the pallet 11 and there is no shaking;

[0088] ② Equipment inspection: Check whether the air pressure of the air hammer 50 (0.6-0.8MPa), the bolt connections (tightening screw 221, turntable bolt 34, etc.) are tight, and whether the circuit and air path are unobstructed.

[0089] (2) Full manual mode operation

[0090] ①Adjust the position:

[0091] Synchronously operate the hand chain hoists 25 on both sides to adjust the height of the slide rail 23 until the hammer head of the air hammer 50 is close to the working surface of the cone. Use a spirit level to check that the slide rail 23 is level, and tighten the tightening screws 221 to lock it.

[0092] Turn the translation hand wheel 27 to move the slider 24 along the slide rail 23 until the air hammer 50 is aligned with the starting position of the working surface;

[0093] Loosen the turntable bolt 34, rotate the telescopic arm 40 to make it parallel to the generatrix of the cone working surface, bring the hammer head of the air hammer 50 close to the working surface, and tighten the turntable bolt 34 to lock the angle.

[0094] ②Start the operation:

[0095] Turn on the turntable motor 12 and adjust the speed of the tray 11 to 1-2 r / min;

[0096] Start the air hammer 50 and start hammering;

[0097] Every 1-3 rotations of the tray 11, manually rotate the telescopic hand wheel to extend / retract the movable arm 42 by 2-3 cm (matching the diameter of the hammer head) to ensure full coverage of the working surface;

[0098] ③ Stop the operation: After visually confirming that all hammering of the working surface is completed, turn off the air hammer 50 and the turntable motor 12, and rotate the telescopic hand wheel in the reverse direction to reset the movable arm 42.

[0099] (3) Semi-automatic mode operation

[0100] ①Parameter setting: Input parameters into the microprocessor through the keyboard (tray rotation number 1-3 circles, extension distance 2-3cm, air hammer frequency 100-200 times / minute), and confirm the parameters on the display;

[0101] ② Adjust the position: Same as step 1 of the full manual mode (height, horizontal position, tilt angle adjustment); ③ Automatic operation:

[0102] Press the "auto start" button, the turntable motor 12 drives the cone to rotate, and the air hammer 50 starts;

[0103] The microprocessor controls the telescopic motor 44 according to preset logic, driving the movable arm 42 to automatically extend and retract, coordinating with the cone rotation to achieve full coverage hammering;

[0104] When the movable arm 42 triggers the telescopic travel switch 45, the equipment automatically stops the telescopic motor 44 and the air hammer 50 to complete the operation.

[0105] (4) End of work

[0106] ① Turn off the main power supply and air supply of the equipment, loosen the tightening screw 134 of the tightening assembly 13, and lift the cone off the machine;

[0107] ② Clean the iron filings from the hammer head of the air hammer 50, check the moving parts (telescopic screw 43, translation screw 26, etc.) and add grease to ensure smooth use next time.
