Description

Technical Field

[0001] The invention relates to the technical field of heat treatment, in particular to a heat treatment device used for cold rolling roller surface spray forming. Background Art

[0002] Cold rolling rollers are tools used to press steel coils or other metal coils into the required thickness and flatness on the cold rolling production line. Cold rolling rollers are often subjected to high-intensity and high-temperature pressure during use. Therefore, injection molding heat treatment is used to improve the hardness, red hardness, wear resistance, fatigue resistance and service life of the rollers. The heat treatment operation can optimize the microstructure of the rollers, making them have better mechanical properties and thermal stability. Spray forming technology is a method of spraying molten or semi-molten metal or alloy onto the surface of the roll to form the desired coating or shape. In the manufacture of cold rolls, spray forming technology can be used to repair roll surface damage, enhance roll surface performance or change roll surface characteristics. The roll after spray forming needs to be heated to ensure a good metallurgical bond between the coating and the substrate. The heating temperature and time need to be precisely controlled according to the properties of the coating material and the substrate material. In combination with the above content, it should be explained that: during the use or production of traditional small cold rolling roller parts, the defective cold rolling roller needs to be surface treated. Affected by the treatment steps, the cold rolling roller after the spray treatment is easily affected by the external environment and uncertain factors during the transportation process while waiting or transporting for heat treatment, resulting in secondary defects, so that the treated cold rolling roller still has defects or quality control problems; In view of the above technical defects, a solution is now proposed.

When the cold rolling roller enters the feeding bin and is suspended between multiple groups of clamps, the cylinder is pushed to drive the moving cylinder to move along the axial direction of the clamp until the moving cylinder drives the rotating cylinder to cover and sleeve the two ends of the cold rolling roller, so as to realize the limited clamping of the single group of cold rolling rollers before the thermal repair treatment; Progressive injection: The upper and lower telescopic cylinders synchronously drive the upper arc frame and the lower arc frame to move closer to each other until a temporary cylindrical ring cover is formed, and the center frame moves along the frame body of the adjustment frame in an arc track until the P1 end section of the center frame can be inserted into the L2 end section of the adjustment frame in the rotating semicircular track; There are multiple groups of micro motors inside the driving seat. When Q1 and Q2 of the driving seat contact the two side frames of the adjusting frame, the micro motor inside the driving seat drives the driving seat to move along the inner wall of the adjusting frame. When Q2 of the driving seat contacts the center frame, the micro motor inside Q2 drives the driving seat to move along the inner wall of the center frame. After Q1 and Q3 gradually separate from the adjusting frame and are in an idle state, the micro motor inside the micro motor stops running, and the propulsion cylinder drives the adjusting frame to move axially along the inner wall of the upper arc frame through the slider, and drives the spray frame to rotate along the circular frame in combination with the driving seat. Compacting treatment: Multiple groups of regulating cylinders drive the pressure rollers to contact the surface of the cold rolling rollers, the driving motor drives the pressure rollers to rotate, the rotary cylinder inside the clamp starts synchronously, and drives the cold rolling rollers clamped by the limit position to rotate synchronously at a limited angle, the driving motor and the rotary cylinder synchronously drive the pressure rollers and the cold rolling rollers to rotate in opposite directions respectively, and the pressure rollers are used to spray the attached materials on the local area of ​​the cold rolling roller surface for compaction; Heat collection treatment: After compaction treatment, the cold rolling roller passes through the buffer bin 2 and enters the high-temperature bin. The outer resistance temperature rack and the inner resistance temperature rack are provided with heat-resistant cylinder parts connected with the outer arc pieces and the inner arc pieces. The heat-resistant cylinder parts drive the outer arc pieces and the inner arc pieces to slide along the outer resistance temperature rack and the inner resistance temperature rack until the end of the outer arc piece M1 is inserted into the top of the inner resistance temperature rack, and the end of the inner arc piece N1 is inserted into the bottom of the outer resistance temperature rack, so that the temperature cylinder mechanism forms a circular cylinder; The heater heats the cold rolling rollers retained inside the circular cylinder. Air pumps are arranged inside the frames of the two outer temperature resistance frames and the inner temperature resistance frame. The air pumps extract high-temperature gas inside the circular cylinder through micropores scattered around the heater, and multiple groups of jet nozzles guide the high-temperature gas to circulate inside the circular cylinder.

[0012] The beneficial effects of the present invention are: 1.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Example 1: Please refer to Figure 1 - Fig.10 As shown, this embodiment is a heat treatment device for cold rolling roller surface spray forming, comprising a temperature lock cylinder cover 1, a middle cylinder 5 is arranged at the center of the temperature lock cylinder cover 1, and a delivery mechanism 4 is arranged on the end surface of the middle cylinder 5; The delivery mechanism 4 includes a special-shaped guide rail 401 and a rotating motor 402, and the end face of the special-shaped guide rail 401 is provided with a clamping cylinder 404 extending to the interior of the temperature-locking cylinder cover 1.

The cold rolling roller is pulled by an external transportation device and fed along the feed cover 3 into the interior of the temperature-locking cylinder cover 1. When the cold rolling roller enters the feed bin 101 and is suspended between multiple groups of clamping cylinders 404, the push cylinder 405 drives the shifting cylinder 410 to move axially along the clamping cylinder 404 until the shifting cylinder 410 drives the rotating cylinder 411 to cover and sleeve the two ends of the cold rolling roller, thereby realizing the limited clamping of a single group of cold rolling rollers before the heat repair treatment; A feed cover 3 is provided on the top of the temperature-locking cylinder cover 1, and a discharge cover 6 is provided on the bottom of the temperature-locking cylinder cover 1.

When the cold rolling roller enters the feed bin 101, the top of the rotating telescopic frame 403 is extended outwards close to the feed cover 3 under the influence of the special-shaped guide rail 401, which is conducive to the connection between the clamping drum 404 and the external equipment to clamp the cold rolling roller; After the two ends of the cold rolling roller are calibrated with the rotating drum 411 in the clamp 404, the pushing cylinder 405 drives the moving drum 410 to approach the two ends of the cold rolling roller, causing the two ends of the cold rolling roller to enter the inside of the rotating drum 411, and the pressure plate 409 is pushed by the two ends of the cold rolling roller. The spring member connecting the pressure plate 409 and the rotating drum 411 is compressed, and the traction line 407 is dragged during the movement of the pressure plate 409. The traction line 407 is linked through multiple groups of guide wheels to drag the clamp 408 hinge to rotate. The clamp 408 hinge is disc-shaped, and several circles of traction line 407 are wrapped around the surface. The clamp 408 is pulled and rotated, and the two ends of the cold rolling roller located inside the rotating drum 411 are clamped in a multi-point wrapped manner.
