Description

Technical Field

[0001] This utility model relates to the field of laser cladding preheating, specifically to a laser cladding preheating device with a heat preservation mechanism. Background Technology

[0002] Laser cladding preheating equipment is a key auxiliary device in the laser cladding process. It is mainly used to preheat the substrate or cladding material before laser cladding to reach the preset temperature, thereby reducing the temperature gradient during the laser cladding process, reducing the accumulation of thermal stress, and avoiding cracking or peeling of the cladding layer, so as to reduce thermal stress, reduce crack generation, and improve the quality of the cladding layer.

[0003] A search revealed a utility model patent with publication number CN220468156U, which discloses a preheating device for laser cladding. This patent addresses the issue that while the heating device is designed for cylindrical objects, it cannot accommodate larger blocky objects, thus failing to meet heating requirements. Furthermore, it cannot adjust its position to change heating direction. The laser cladding machine is equipped with a preheating mechanism on one side, with an electrically powered heating block installed below it. A fixed sleeve is fitted around the laser cladding machine and rotatably connected to it via bearings. One end of the fixed sleeve is fixedly connected to one side of the upper part of the preheating mechanism. A servo motor is installed on the other side of the upper part of the laser cladding machine, with a first sprocket fitted around its output end. A second sprocket is fitted around the upper part of the fixed sleeve.

[0004] In existing laser cladding preheating devices, preheating is usually performed in advance, so laser cladding processing is not carried out immediately after preheating. A short waiting period is required, during which the preheating temperature is prone to drop, thus affecting the laser cladding processing. Existing laser cladding preheating devices do not have effective heat preservation measures, so they cannot solve the problem of temperature loss during the waiting period after preheating.

[0005] Therefore, it is necessary to invent a laser cladding preheating device with a heat preservation mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a laser cladding preheating device with a heat preservation mechanism. After preheating, a few groups of heating rods can be independently controlled to be turned on, thereby achieving heat preservation while reducing energy consumption, thus solving the problem that preheated materials cannot be kept warm in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a laser cladding preheating device with a heat preservation mechanism, including a base, a preheating cylinder installed on one side above the base, four sets of connecting plates arranged in a ring inside the preheating cylinder, three sets of heating rods installed on one side of each of the four sets of connecting plates, and a material guide platform installed on one side above the base.

[0008] The adjustment component installed inside the preheating cylinder includes a rotating cylinder, which is installed through the preheating cylinder. A positioning ring is fixedly fitted onto the rotating cylinder. An annular groove is provided on the inner wall of the preheating cylinder, and the positioning ring is slidably connected to the annular groove.

[0009] The drive assembly located above the base includes a servo motor, which is mounted above the preheating cylinder. A gear is installed at the output end of the servo motor, and a gear ring is fitted and fixed on the rotating cylinder, with the gear ring meshing with the gear.

[0010] Preferably, the adjustment assembly further includes extension plates, which are symmetrically installed in a ring at the edge of the rotating cylinder, and each set of extension plates has an annular groove.

[0011] Preferably, each of the extension plates in each group is connected through an internally threaded cylinder, and each of the internally threaded cylinders is fitted with a positioning ring two, which is slidably connected to the corresponding annular groove two.

[0012] Preferably, a screw is screwed into the internal threaded cylinder, and the lower part of the screw is rotatably connected to the side of the corresponding connecting plate away from the heating rod. Limiting rods are symmetrically installed on the side of the connecting plate near the screw, and the limiting rods are connected through the inner wall of the rotating cylinder.

[0013] Preferably, the drive assembly further includes a feeding box, which is installed on the side of the base away from the preheating cylinder. A second screw is rotatably connected inside the feeding box. A feeding platform is provided inside the feeding box, and the feeding platform is threaded through and screwed to the second screw. A guide platform is also installed above the feeding platform.

[0014] Preferably, guide rods are symmetrically installed inside the feeding box, and the guide rods are connected through the feeding table. A second gear is rotatably connected to the outside of the feeding box, and the second gear is axially connected to the second screw. The second gear meshes with the gear ring.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By rotating the internal threaded cylinder and pushing the screw, the position of the heating rod is changed by the connecting plate, thus achieving adjustment according to the size of the material. Furthermore, through independent control of the heating rods, some heating rods can be activated to achieve a heat preservation effect. This structure allows the equipment to be adjusted according to the size of the material, thereby improving the preheating effect. Preheating can be fully automatic, and after preheating, the number of activated heating rods can be reduced to achieve a better heat preservation effect while significantly reducing energy consumption. The rotary heating during the heating process greatly improves the uniformity of preheating. Finally, the modular design of the heating rods significantly reduces the later maintenance costs of the equipment. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-4 The laser cladding preheating device with a heat preservation mechanism shown includes a base 001, a preheating cylinder 101 installed on one side above the base 001, four sets of connecting plates 102 arranged in a ring inside the preheating cylinder 101, three sets of heating rods 103 installed on one side of each of the four sets of connecting plates 102, and a guide platform 104 installed on one side above the base 001.

[0026] The guide plate 104 can support the preheated material, and the four sets of connecting plates 102 are arranged in a ring, with the heating rods 103 distributed around the material to achieve the preheating effect. Furthermore, the heating rods 103 of the four sets of connecting plates 102 can be controlled independently.

[0027] The adjustment component 002 installed in the preheating cylinder 101 includes a rotating cylinder 201, which is installed through the preheating cylinder 101. A positioning ring 202 is sleeved and fixed on the rotating cylinder 201. An annular groove 203 is provided on the inner wall of the preheating cylinder 101, and the positioning ring 202 is slidably connected to the annular groove 203.

[0028] The positioning ring 202 and the annular groove 203 work together to make the rotating drum 201 rotate stably inside the preheating drum 101.

[0029] The drive assembly 003, located above the base 001, includes a servo motor 301. The servo motor 301 is mounted above the preheating cylinder 101. A gear 302 is mounted on the output end of the servo motor 301. A gear ring 303 is sleeved and fixed on the rotating cylinder 201, and the gear ring 303 meshes with the gear 302.

[0030] The servo motor 301 can drive the gear 302 to rotate, which in turn drives the rotating drum 201 to rotate via the gear ring 303.

[0031] Furthermore, in the above structure, the adjustment component 002 also includes an extension plate 204, which is symmetrically installed in a ring at the edge of the rotating cylinder 201, and each set of extension plates 204 has an annular groove 205.

[0032] Furthermore, in the above structure, each set of extension plates 204 is connected through an internal threaded cylinder 206, and each set of internal threaded cylinders 206 is fitted with a positioning ring 207, and the positioning ring 207 is slidably connected to the corresponding annular groove 205.

[0033] The internal threaded cylinder 206 can rotate at a fixed point within the extension plate 204 through the cooperation of the positioning ring 207 and the annular groove 205.

[0034] Furthermore, in the above structure, a screw rod 208 is screwed into the internal threaded cylinder 206. The lower part of the screw rod 208 is rotatably connected to the side of the corresponding connecting plate 102 away from the heating rod 103. Limiting rods 209 are symmetrically installed on the side of the connecting plate 102 near the screw rod 208, and the limiting rods 209 are connected through the inner wall of the rotating cylinder 201.

[0035] The screw 208 can be moved by the internal threaded cylinder 206, thereby changing the position of the connecting plate 102 in the rotating cylinder 201, and changing the position between the heating rod 103 and the material. This allows for adjustment according to the size of the material, and the limiting rod 209 ensures the stable movement of the connecting plate 102.

[0036] Furthermore, in the above structure, the drive assembly 003 also includes a feeding box 304, which is installed on the side above the base 001 away from the preheating cylinder 101. A screw 305 is rotatably connected inside the feeding box 304, and a feeding platform 306 is provided inside the feeding box 304. The feeding platform 306 is threaded through and screwed to the screw 305, and a guide platform 104 is also installed above the feeding platform 306.

[0037] The screw 305 can drive the feeding table 306 to move, so that the guide table 104 above the feeding table 306 can push the material through the inside of the rotating drum 201.

[0038] Furthermore, in the above structure, guide rods 307 are symmetrically installed inside the feeding box 304, and the guide rods 307 are connected through the feeding table 306. Gear 2 308 is rotatably connected to the outside of the feeding box 304, and gear 2 308 is shaft-connected to screw 2 305. Gear 2 308 meshes with gear ring 303.

[0039] The stable movement of the feeding box 304 is achieved through the cooperation of the guide rod 307 and the feeding table 306, and the cooperation of the gear 2 308 and the gear ring 303 can transmit the power of the servo motor 301 to the screw 2 305.

[0040] The working principle of this practical application is as follows:

[0041] Refer to the instruction manual appendix Figure 1-4The rotation of the internal threaded cylinder 206 pushes the screw 208 to move, thereby causing the connecting plate 102 to move the heating rod 103 within the rotating drum 201. This allows the position of the heating rod 103 to be adjusted according to the material size for better preheating. The material is then placed and fixed above the guide table 104, and the servo motor 301 is activated, causing it to drive the gear 302 to rotate. The gear 302, through the gear ring 303, drives the rotating drum 201 to rotate. Simultaneously, the gear ring 303 drives the gear 308 to rotate, causing the screw 305 to move the feeding table 306 within the feeding box 304, thus allowing the material to enter the positions between the heating rods 103. The feeding table 306 reciprocates to achieve preheating. After preheating, the heating rods 103 on one side of the two sets of connecting plates 102 are turned on, and the above action is repeated to achieve heat preservation and effectively reduce energy consumption. This structure allows the equipment to be adjusted according to the size of the material, thereby improving the preheating effect. Preheating can be fully automatic. After preheating, the number of heating rods 103 turned on can be reduced to achieve heat preservation while greatly reducing energy consumption. The rotational heating during the heating process can greatly improve the uniformity of preheating. Finally, the modular design of the heating rods 103 can greatly reduce the maintenance cost of the equipment in the later stage.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
