Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and in particular relates to an anti-oxidation and heat-insulating feeding device. Background Technology

[0002] In the manufacturing of shaft parts and wires, extrusion is a highly efficient and low-cost processing method that can extrude bars into shape in a single step or with only a small amount of processing to obtain the target part. It is widely used in the manufacturing of automotive parts, instruments, and home appliances. In extrusion molding production lines, the feeding device is a crucial component, eliminating manual feeding, preventing safety accidents, and effectively improving production efficiency. Automated extrusion production lines require a precise feeding device that can work in tandem with the forming equipment to complete the required forming process. Currently, such feeding devices have certain limitations: firstly, to reduce extrusion pressure, the blank is often heated, but this temperature drops during feeding, accelerating oxide formation around the blank; secondly, due to the special properties of the material, the exposure time to air must be controlled during the manufacturing of certain special metal parts to prevent oxidation; and thirdly, transporting the blank to the extrusion center requires the cooperation of multiple actuators and detection elements, leading to component redundancy in the production line. All of these factors can seriously affect product quality and increase manufacturing costs. Utility Model Content

[0003] The purpose of this invention is to provide an anti-oxidation and heat-insulating feeding device that can keep the heated blank warm during the feeding process, significantly reduce the temperature drop during the feeding process, ensure stable extrusion pressure, and control the time the blank is exposed to air.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: an anti-oxidation and heat-insulating feeding device, comprising a transfer unit, a material support frame, a storage cylinder, and a sealing unit; the transfer unit is used to transfer the material support frame, the storage cylinder is fixed on the material support frame, the storage cylinder is provided with a feeding port, and the sealing unit can close the feeding port; the storage cylinder is provided with an insulation layer inside, and the insulation layer does not produce a chemical reaction with the heated blank; the storage cylinder is provided with an air inlet, and the air inlet is connected to a protective gas storage device.

[0005] Furthermore, the sealing unit includes a support base, a flip cover, and a sealing drive component. The support base is fixed on the storage cylinder, and the flip cover is rotatably connected to the support base. One end of the sealing drive component is rotatably connected to the material support frame, and the other end is rotatably connected to one side of the flip cover. The sealing drive component is used to drive the flip cover to rotate and seal the feed inlet.

[0006] Furthermore, the transfer unit includes a support base and a transfer drive component, the transfer drive component is mounted on the support base, and the drive end of the transfer drive component is connected to the material support frame.

[0007] Furthermore, the support seat is provided with a guide hole, and a guide rod is slidably connected in the guide hole, with one end of the guide rod connected to the material support frame.

[0008] Furthermore, a sensing head is provided on the side of the guide rod away from the material support frame, and a sensing frame is provided on the support base. The sensing frame is provided with a starting sensing element for sensing the material support frame and an ending sensing element for sensing the sensing head. The starting sensing element and the ending sensing element are respectively located on both sides of the support base. The starting sensing element and the ending sensing element are respectively used to limit the operating limit position of the transfer drive element.

[0009] Furthermore, the starting sensor and the ending sensor are respectively connected to the controller, which is used to control the movement of the transfer drive.

[0010] Furthermore, the starting sensing element includes a first limit switch and a second limit switch, which are distributed along the driving direction of the transfer drive element. The first limit switch is located on the side closer to the support seat. The controller decelerates the transfer drive element according to the sensing signal of the second limit switch and shuts down the transfer drive element according to the sensing signal of the first limit switch.

[0011] Furthermore, the end sensor includes a third limit switch and a fourth limit switch, which are distributed along the driving direction of the transfer drive, with the third limit switch located on the side closer to the support seat; the controller decelerates the transfer drive based on the sensing signal of the fourth limit switch and shuts down the transfer drive based on the sensing signal of the third limit switch.

[0012] Furthermore, the load-bearing seat is fixed to the bracket.

[0013] Furthermore, the storage cylinder is provided with inlets on both sides, and the sealing unit is provided in two sets.

[0014] The working principle of this technical solution is as follows: The sealing drive component rotates the flip cover, opening the feed inlet. The heated blank is then added into the storage cylinder through the feed inlet. During this process, the protective gas storage device is activated, filling the storage cylinder with protective gas. After feeding is complete, the sealing drive component is reversed, causing the flip cover to rotate in the opposite direction, closing the feed inlet and shutting off the protective gas storage device. The transfer drive component is then activated, its output driving the material support frame to move. During this process, the guide rod also moves with the material support frame. When the fourth limit switch no longer senses the sensing head, the controller sends a deceleration command to the transfer drive component, causing it to slow down. When the third limit switch no longer senses the sensing head, the controller sends a stop command to the transfer drive component, causing it to stop. At this point, the storage cylinder has reached the designated position, and the sealing drive component rotates the flip cover, opening the feed inlet and allowing the blank to be removed from the storage cylinder.

[0015] The reverse drive transfer drive unit drives the material carrier to move in the opposite direction. During this process, the second limit switch will sense the material carrier first, and the controller will send a deceleration command to the transfer drive unit, causing the transfer drive unit to decelerate. When the first limit switch senses the material carrier, the controller will send a stop command to the transfer drive unit, causing the transfer drive unit to stop.

[0016] The beneficial effects of this technical solution are as follows:

[0017] ① The storage cylinder is equipped with an insulation layer to keep the blank warm, significantly reducing temperature drop during the feeding process and ensuring stable extrusion pressure. Furthermore, a protective gas is introduced during feeding to reduce the blank's contact with air, thereby minimizing oxidation.

[0018] ② The guide rod can improve guiding accuracy, reduce wear on the seals of the transfer drive components, and improve the accuracy of the feeding device.

[0019] ③ The setting of the starting and ending sensors can control the deceleration, extension into position and retraction into position of the transfer drive, so as to achieve precise positioning. Attached Figure Description

The sensor frame 12 has a starting sensor for sensing the material support frame 6 and an ending sensor for sensing the sensor head 18. The starting sensor is located below the material support frame 6, and the ending sensor is located below the sensor head 18. The starting sensor and the ending sensor are respectively connected to a controller, which controls the movement of the transfer drive 3. The starting sensor and the ending sensor are located on both sides of the support base 2; the starting sensor and the ending sensor are used to limit the operating limit positions of the transfer drive 3. The starting sensor includes a first limit switch 13 and a second limit switch 14, which are distributed along the driving direction of the transfer drive 3.
