Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a laser heat treatment device for mold manufacturing. Background Technology

[0002] Mold heat treatment is a crucial step in mold manufacturing, directly affecting the mold's service life, precision, and performance. There are many types of mold heat treatment processes, which can be broadly categorized into three types based on their purpose and characteristics: overall heat treatment, surface heat treatment, and chemical heat treatment. Among these, laser heat treatment is an advanced surface modification technology. It uses a high-energy laser beam to rapidly scan the workpiece, causing the surface temperature of the irradiated metal or alloy to rise extremely quickly above its phase transition point. When the laser beam leaves the irradiated area, the cooled substrate undergoes rapid cooling due to heat conduction, resulting in self-cooling quenching and a finer hardened layer structure. The hardness is generally higher than that of conventional quenching, and the workpiece deformation during the process is minimal. It is suitable for surface strengthening of certain workpieces or localized areas of workpieces that cannot be achieved or are difficult to achieve with other quenching techniques. Laser heat treatment has a high degree of automation, and the depth and area of ​​the hardened layer are well-controllable. Its application in mold manufacturing is increasingly widespread, especially suitable for localized strengthening and the processing of complex-shaped molds.

[0003] The main components of laser heat treatment equipment include: CNC machine tool, laser, beam transmission and focusing system, temperature monitoring and control system, auxiliary system and safety protection system. During operation, the mold to be treated is fixed on the machine tool's worktable. The machine tool spindle raises and lowers the laser to adjust its height. Then, the worktable moves along the X-axis or Y-axis to perform heat treatment, and drives the spindle to rotate at a certain angle to adjust the laser's irradiation direction.

[0004] Due to the wide variety of mold types and their different structures, the laser irradiation angle is generally difficult to adjust for some molds or inserts with tilt angles. Usually, appropriate fixtures are used to adjust the tilt surface of the mold or insert to be parallel to the horizontal plane of the worktable to facilitate laser irradiation. However, as the mold type and structure change, appropriate fixtures need to be made or purchased, which increases the cost of use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the irradiation angle of the laser is inconvenient to adjust in the prior art, and that it requires the use of fixtures to adjust the angle of the mold or insert, which leads to increased usage costs. Therefore, this invention proposes a laser heat treatment device for mold production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser heat treatment device for mold production includes a fixed plate mounted on a machine tool spindle, a laser body disposed on the fixed plate, and a vertical plate fixedly disposed on one side of the fixed plate. The fixed plate and the vertical plate form an L-shaped structure. A mounting plate is rotatably disposed on the end of the vertical plate away from the fixed plate. The laser body is mounted on the end face of the mounting plate away from the fixed plate, and a driving part for driving the mounting plate to rotate is disposed on the vertical plate.

[0008] To ensure reliable rotation of the mounting plate, preferably, a rotation groove is provided at the end of the vertical plate away from the fixed plate, a rotating block is fixedly provided at one end of the mounting plate, and a rotating shaft is fixedly provided on both sides of the rotating block, with the rotating shaft rotatably disposed in the rotation groove.

[0009] To facilitate the rotation of the drive plate to adjust the irradiation angle of the laser body, the drive unit further includes a worm gear. The outer wall of the vertical plate is provided with a mounting groove. One end of a set of rotating shafts extends into the mounting groove and is fixedly connected to the worm gear. A servo motor is fixedly installed in the mounting groove, and a fixed shaft is fixedly installed at the output end of the servo motor. A worm is fixedly installed at the end of the fixed shaft away from the servo motor, and the worm meshes with the worm gear.

[0010] To facilitate the assembly and disassembly of the fixing plate and the machine tool spindle, preferably, the fixing plate has a first central hole, a positioning sleeve is fixedly installed at the bottom of the machine tool spindle, the positioning sleeve is slidably installed in the first central hole, and the fixing plate has a first through hole, and the fixing plate is fixedly installed at the bottom of the machine tool spindle by a first bolt.

[0011] Furthermore, a limiting block is fixedly installed inside the first central hole, and a limiting groove is formed on the outer wall of the positioning sleeve, with the limiting block slidably disposed within the limiting groove.

[0012] Furthermore, a second through hole is provided on the mounting plate, the laser body is fixedly mounted on the mounting plate by a second bolt, and a second center hole coaxial with the first center hole is provided on the mounting plate. A power connection post is fixedly provided on the top of the laser body, and the power connection post is slidably mounted in the second center hole by a connecting key. A connecting wire electrically connected to the power connection post is provided on the machine tool spindle.

[0013] Compared with the prior art, this utility model provides a laser heat treatment device for mold production, which has the following beneficial effects:

[0014] 1. This laser heat treatment device for mold production has a fixed plate fixed on the machine tool spindle, a vertical plate fixed on the fixed plate, and a mounting plate rotatably mounted on the bottom of the vertical plate. The laser body is fixed on the mounting plate. The servo motor is started to drive the worm gear to rotate. Through the meshing of the worm gear and the worm wheel, the mounting plate can be driven to rotate around the axis of the rotating shaft, thereby adjusting the irradiation angle of the laser body. This reduces the use of special fixtures and helps to reduce the cost of use.

[0015] 2. The laser heat treatment device for mold production can ensure the installation angle of the fixed plate by fixing a limiting block that matches the upper limit groove of the positioning sleeve in the first central hole. Since the rotation of the machine tool spindle can change the irradiation direction of the laser body, the parameters for adjusting the irradiation direction of the laser body by rotating it can remain unchanged, thus improving the performance.

[0016] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model fixes a fixed plate on the machine tool spindle, fixes a vertical plate on the fixed plate, and rotatably sets a mounting plate at the bottom of the vertical plate. The laser body is fixed on the mounting plate, and the mounting plate is driven by the drive unit to rotate around the axis of the rotating shaft, thereby adjusting the irradiation angle of the laser body. This reduces the use of special fixtures and helps to reduce the cost of use. Attached Figure Description

[0024] Example:

[0025] Reference Figures 1-4 A laser heat treatment device for mold production includes a fixed plate 1 mounted on a machine tool spindle, a laser body 4 disposed on the fixed plate 1, and a vertical plate 2 fixedly disposed on one side of the fixed plate 1. The fixed plate 1 and the vertical plate 2 form an L-shaped structure, and the joint between the vertical plate 2 and the fixed plate 1 is transitioned by a rounded corner. A mounting plate 3 is rotatably disposed at the end of the vertical plate 2 away from the fixed plate 1. The laser body 4 is mounted on the end face of the mounting plate 3 away from the fixed plate 1. The vertical plate 2 is provided with a driving part for driving the mounting plate 3 to rotate. In the initial state, the mounting plate 3 is directly below the fixed plate 1. The top and bottom faces of mounting plate 3 are parallel to the top and bottom faces of fixing plate 1. In use, fixing plate 1 is mounted on the machine tool spindle, and then laser body 4 is mounted on mounting plate 3. Then, the drive unit drives mounting plate 3 to rotate laser body 4 by a certain angle, thereby adjusting the irradiation angle of laser body 4 and irradiating the inclined surface of mold or insert. Due to its own weight, mold or insert can be placed directly on the machine tool worktable or fixed on the worktable using a pressure plate. The fixing method is simple, which can reduce the use of special fixtures and help reduce the cost of use.

[0026] Reference Figures 2-4 A rotating groove 201 is provided at the end of the vertical plate 2 away from the fixed plate 1. A rotating block 301 is fixedly installed at one end of the mounting plate 3. A rotating shaft is fixedly installed on both sides of the rotating block 301. The rotating shaft is rotatably installed in the rotating groove 201. In use, by fixing the rotating block 301 on the mounting plate 3 and fixing the rotating shaft on the rotating block 301, the rotating shaft is rotatably installed in the rotating groove 201, which can ensure that the mounting plate 3 can rotate reliably and prevent it from falling off the vertical plate 2 and affecting normal use.

[0027] Reference Figure 3Here, we design the drive unit as a worm gear 302. A mounting groove 202 is provided on the outer wall of the vertical plate 2. One end of a set of rotating shafts extends into the mounting groove 202 and is fixedly connected to the worm gear 302. A servo motor 502 is fixedly installed in the mounting groove 202, and a fixed shaft 5 is fixedly installed at the output end of the servo motor 502. A worm 501 is fixedly installed at the end of the fixed shaft 5 away from the servo motor 502. The worm 501 meshes with the worm gear 302. In use, by starting the servo motor 502, the worm 501 is rotated. Through the meshing of the worm 501 and the worm gear 302, the mounting plate 3 can be driven to rotate around the axis of the rotating shaft, thereby adjusting the irradiation angle of the laser body 4 and improving the usage effect.

[0028] Reference Figures 1-3 A first central hole 101 is provided on the fixed plate 1, and a positioning sleeve is fixedly provided at the bottom of the machine tool spindle. The positioning sleeve is slidably disposed in the first central hole 101. A first through hole 102 is provided on the fixed plate 1, and the fixed plate 1 is fixedly disposed at the bottom of the machine tool spindle by a first bolt. That is, the first bolt passes through the first through hole 102 and is fixedly connected to the machine tool spindle. The fixed plate 1 is easy to install and remove and is reliably fixed. A limit block 103 is fixedly provided in the first central hole 101. The limit block 103 extends along the axial direction of the first central hole 101. A limit groove is provided on the outer wall of the positioning sleeve. The limit block 103 is slidably disposed in the limit groove. By fixing the limit block 103 in the first central hole 101 and matching the limit groove of the positioning sleeve, the installation angle of the fixed plate 1 can be guaranteed. Since the rotation of the machine tool spindle can change the irradiation direction of the laser body 4, the parameters for adjusting the irradiation direction of the laser body 4 by rotation can remain unchanged, thereby improving the performance.

[0029] Reference Figures 1-3 A second through hole is provided on the mounting plate 3. The laser body 4 is fixed on the mounting plate 3 by a second bolt. That is, one end of the second bolt passes through the second through hole and is threaded to the laser body 4, thereby fixing the laser body 4 to the mounting plate 3. A second center hole coaxial with the first center hole 101 is provided on the mounting plate 3. A power supply post is fixedly provided on the top of the laser body 4. The power supply post is slidably set in the second center hole by a connecting key. That is, a connecting key is fixedly provided in the second center hole. The connecting key can limit the installation position of the laser body 4, corresponding to the limiting groove on the limiting block 103 and the positioning sleeve. A connecting wire electrically connected to the conductive post is provided on the machine tool spindle. The connecting wire passes out from the positioning sleeve and then plugs into the conductive post to provide power to the laser body 4. Since the rotation range of the machine tool spindle is generally within the range of 0°-180°, the connecting wire is less likely to get tangled, thus improving the performance.

[0030] In this invention, a fixing plate 1 is fixedly mounted on the machine tool spindle, a vertical plate 2 is fixedly mounted on the fixing plate 1, and a mounting plate 3 is rotatably mounted at the bottom of the vertical plate 2. The laser body 4 is fixed on the mounting plate 3. When the servo motor 502 is started, it drives the worm gear 501 to rotate. Through the meshing of the worm gear 501 and the worm wheel 302, the mounting plate 3 can be driven to rotate around the axis of the rotating shaft, thereby adjusting the irradiation angle of the laser body 4. This reduces the use of special fixtures and helps to reduce the cost of use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
