Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipeline production equipment, specifically to a mandrel release agent coating device. Background Technology

[0002] Mandrels used in hydraulic pipe production are key tools for supporting and guiding pipes to maintain their shape during bending or extrusion. Their material, shape, and installation position directly affect quality indicators such as pipe ovality and wall thickness uniformity. Before use, mandrels need to be coated with a release agent to ensure smooth demolding of subsequent adhesive materials. However, existing release agent coating methods generally involve manual brushing, which is not precise and easily leads to uneven coating. In severe cases, this can cause subsequent demolding difficulties. Therefore, it is necessary to design a mandrel release agent coating device that can uniformly coat the release agent. Utility Model Content

[0003] The purpose of this invention is to provide a mandrel release agent coating device, which has the advantage of being able to uniformly coat the release agent.

[0004] The technical solution adopted is as follows: A mandrel release agent coating device includes a frame, a release agent supply unit, and a coating mechanism. The coating mechanism includes a mounting cylinder and a feeding brush. The mounting cylinder is horizontally arranged and rotatably connected to the frame. One end of the mounting cylinder is coaxially connected to a coating ring. The feeding brush contacts the upper end of the coating ring. The release agent supply unit includes a storage tank. A release agent delivery pump is connected inside the storage tank. The release agent delivery pump is provided with a delivery pipe connected to the feeding brush. A drive mechanism connected to the mounting cylinder is provided on the frame.

[0005] Preferably, the drive mechanism includes a motor, a drive gear, and a driven gear ring. The motor and the drive gear are connected, the driven gear ring is fixedly connected to the mounting cylinder, and the driven gear ring meshes with the drive gear.

[0006] Preferably, a curing ring is provided in front of the coating ring, and multiple sets of electric heating wires are uniformly arranged on the inner side of the curing ring.

[0007] Preferably, the coating ring is made of porous plastic material.

[0008] Preferably, the storage tank is equipped with a remaining capacity alarm.

[0009] Compared to existing technologies, the advantages are: This invention delivers the release agent to the feeding brush via a release agent supply unit. The feeding brush contacts the coating ring, thereby supplying the release agent to the coating ring. The mandrel passes through the coating ring, and the driving mechanism drives the coating ring to rotate. The coating ring evenly coats the mandrel with the release agent, resulting in uniform coating and excellent subsequent demolding effect. Attached Figure Description

[0011] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown: Example 1: A mandrel release agent coating device includes a frame 1, a release agent supply unit and a coating mechanism. The release agent supply unit and the coating mechanism are both mounted on the frame 1. The coating mechanism includes a mounting cylinder 2 and a feeding brush 3. The mounting cylinder 2 is horizontally arranged and rotatably connected to the frame 1. One end of the mounting cylinder 2 is coaxially connected to a coating ring 4.

[0012] The feeding brush 3 contacts the upper end of the coating ring 4. The mold release agent supply unit includes a storage tank 5, which contains mold release agent. A mold release agent delivery pump is connected to the storage tank 5. The mold release agent delivery pump is existing technology and will not be described in detail here. The mold release agent delivery pump is equipped with a delivery pipe 10 connected to the feeding brush 3. The mold release agent delivery pump delivers the mold release agent to the feeding brush 3. A drive mechanism connected to the mounting cylinder 2 is provided on the frame 1. The drive mechanism drives the mounting cylinder 2 to rotate.

[0013] The mold release agent supply unit delivers the mold release agent to the feeding brush 3, which contacts the coating ring 4 to supply the mold release agent to the coating ring 4. The mandrel passes through the coating ring 4, and the drive mechanism drives the coating ring 4 to rotate, so that the coating ring 4 evenly coats the mandrel with the mold release agent.

[0014] Example 2: A mandrel release agent coating device includes a frame 1, a release agent supply unit and a coating mechanism. The release agent supply unit and the coating mechanism are both mounted on the frame 1. The coating mechanism includes a mounting cylinder 2 and a feeding brush 3. The mounting cylinder 2 is horizontally positioned and rotatably connected to the frame 1. One end of the mounting cylinder 2 is coaxially connected to a coating ring 4, which is made of porous plastic material.

[0015] The feeding brush 3 contacts the upper end of the coating ring 4. The mold release agent supply unit includes a storage tank 5. The storage tank 5 is equipped with a level alarm. When the level of mold release agent is low, the level alarm will sound an alarm. The storage tank 5 contains mold release agent. The storage tank 5 is connected to a mold release agent delivery pump. The mold release agent delivery pump is existing technology and will not be described in detail here. The mold release agent delivery pump is equipped with a delivery pipe 10 connected to the feeding brush 3. The mold release agent delivery pump delivers the mold release agent to the feeding brush 3. The frame 1 is equipped with a drive mechanism connected to the mounting cylinder 2. The drive mechanism drives the mounting cylinder 2 to rotate.

[0016] The drive mechanism includes a motor 6, a drive gear 7, and a driven gear ring 8. The motor 6 and the drive gear 7 are connected. The driven gear ring 8 is fixedly connected to the mounting cylinder 2 and meshes with the drive gear 7. A curing ring 9 is provided in front of the coating ring 4. Multiple sets of electric heating wires are evenly arranged on the inner side of the curing ring 9. The electric heating wires heat and cure the core rod coated with the release agent.

[0017] The working principle is as follows: The electric heating wire is started, and the mold release agent delivery pump is started. The mold release agent supply unit delivers the mold release agent to the feeding brush 3. The feeding brush 3 contacts the coating ring 4 to supply the mold release agent to the coating ring 4. The mandrel passes through the coating ring 4. The drive mechanism drives the coating ring 4 to rotate. The coating ring 4 evenly coats the mold release agent on the mandrel. The electric heating wire heats and cures the mandrel after it has been coated with the mold release agent. The mold release agent is evenly coated, resulting in a good subsequent demolding effect.
