Description

Technical Field

[0001] The invention relates to the field of workpiece processing, and in particular to a medium-frequency induction through-type tempering device for directional arrangement of workpieces. Background Art

[0002] Tempering is a metal heat treatment process that reheats the quenched workpiece to an appropriate temperature below the lower critical temperature Ac1 (the starting temperature of pearlite to austenite transformation during heating), keeps it warm for a period of time, and then cools it in air, water, oil or other media. Or the quenched alloy workpiece is heated to an appropriate temperature, kept warm for a certain period of time, and then slowly or quickly cooled. It is generally used to reduce or eliminate the internal stress in the quenched steel parts, or reduce its hardness and strength to improve its ductility or toughness. The quenched workpiece should be tempered in time. Only through the combination of quenching and tempering can the required mechanical properties be obtained.

[0003] At present, we usually use two methods in tempering equipment, induction tempering, mesh belt tempering furnace or various traditional tempering furnaces. In induction tempering equipment, for asymmetrical workpieces, we rotate the workpiece to reduce the impact of the shape on the heat treatment, but the production cycle is long, which seriously restricts productivity; in traditional tempering furnaces or mesh belt tempering equipment, although the amount of tempering is large at one time and there is no cycle problem, the consistency of the placement direction cannot be guaranteed, so the quality after tempering cannot be guaranteed. Today's workpieces (such as automobile hub shafts) have very fast production cycle requirements, and the tempering quality of all workpieces needs to be consistent, so some traditional methods can no longer meet production and process requirements. Summary of the invention

[0004] In order to solve the technical problem of inconsistent tempering quality of different workpieces, the present invention provides a medium-frequency induction through-type tempering device for directional arrangement of workpieces.

[0007] Through the above technical solution, the workpieces can be placed in the same direction during tempering, thereby ensuring quality consistency, shortening the cycle as much as possible, and improving production efficiency.

[0008] As a further improvement of the above scheme, the laser positioning mechanism includes a supporting bracket, a rotating shaft is rotatably arranged in the middle of the upper side of the supporting bracket, a rotating motor is fixedly connected to the lower side of the supporting bracket, the output end of the rotating motor drives the rotating shaft to rotate through a synchronous belt, a bracket for supporting the workpiece is arranged at the top of the rotating shaft, and a first laser probe, a second laser probe and a corresponding shooting switch are arranged circumferentially around the bracket on the upper side of the supporting bracket.

[0009] Through the above technical solution, it is possible to capture and set two specific adjacent points to ensure that the workpiece stops after turning to the same position each time, thereby ensuring the consistency of the direction of the workpiece each time it stops.

[0010] As a further improvement of the above scheme, the conveying mechanism includes a fixed bracket located on one side of the laser positioning mechanism, a second robotic arm that moves horizontally is provided at the upper end of the fixed bracket, a first robotic arm that moves up and down is provided at one end of the second robotic arm, and a three-jaw chuck that moves the workpiece on the support to the tempering induction mechanism is provided on the lower side of the first robotic arm.

[0011] Through the above technical solution, the workpiece can be clamped and taken out from the laser positioning mechanism and transported to the positioning sleeve on the tempering flat chain to ensure the accuracy of the tempering position.

[0012] As a further improvement of the above scheme, the sliding mechanism includes a flat chain arranged on the upper side of the tempering platform, a plurality of positioning sleeves for placing workpieces are arranged on the upper side of the flat chain, and a servo drive mechanism for driving the flat chain to rotate is arranged at one end of the tempering platform.

[0013] Through the above technical solution, the workpieces can pass through the tempering induction coil in sequence, so that the tempering is fully uniform.

[0014] As a further improvement of the above solution, the servo drive mechanism includes a servo motor fixedly connected to one end of the tempering platform, and the output end of the servo motor drives the flat chain to rotate through a synchronous belt and a synchronous pulley.

[0015] Through the above technical solution, the workpiece can be stably passed through the tempering coil, so that the tempering of different workpieces is consistent.

[0016] As a further improvement of the above scheme, the induction tempering mechanism includes a tempering induction coil arranged on the upper side of the tempering platform and located on both sides of the sliding mechanism, the height of the tempering induction coil is adjusted, and a plurality of first guide rods and a plurality of second guide rods are arranged on the upper side of the tempering platform, and the plurality of first guide rods and the second guide rods are respectively arranged on both sides of the sliding mechanism, and the lower sides of the plurality of first guide rods and the second guide rods are fixedly connected with vertical rods, and the bottoms of the plurality of vertical rods are provided with a base located on the upper side of the tempering platform.

[0017] Through the above technical solution, the workpiece can be tempered quickly to ensure that the tempering degree of each workpiece is consistent.

[0018] As a further improvement of the above scheme, the temperature measuring mechanism includes a vertically arranged guide shaft, two pillars are arranged on the upper side of the guide shaft, a scale plate is arranged between the two pillars, a fixing clamp is arranged on one side of the scale plate, and an infrared thermometer for measuring the temperature of the workpiece is arranged on the upper side of the fixing clamp.

[0019] Through the above technical solution, the temperature of the workpiece can be measured in real time, so that the tempering performance of the workpiece is better.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the laser positioning mechanism, the workpiece is driven by a rotating motor. During the rotation process, the first laser probe, the second laser probe and the shooting switch can capture and set specific adjacent two points to ensure that each time it rotates to the same position and then stops, thereby ensuring the consistency of the direction of the workpiece after each stop. The workpiece is then clamped out of the laser positioning mechanism by the first and second robotic arms and transported to the positioning sleeve on the tempering flat chain. The action is repeated, and the flat chain is set to a stepping movement mode through the servo reducer drive, so that the workpiece forms a directional arrangement, and then is tempered one by one through the medium-frequency tempering induction coil and discharged in an orderly manner, achieving the effect of stable tempering performance.

[0022] 2. By adjusting the height of the tempering induction coil, workpieces of different sizes can be subjected to induction tempering, making the tempering adaptation effect better to meet the tempering process requirements. BRIEF DESCRIPTION OF THE DRAWINGS
