Description

Technical Field

[0001] This utility model relates to the field of abrasive technology, specifically to a hoisting spiral cooling device. Background Technology

[0002] In the industrial manufacturing sector, especially in high-temperature processing scenarios (such as metal casting, heat treatment, and mold processing), cooling of processing equipment or workpieces is a crucial step in ensuring production efficiency and product quality. With the increasing demand for automated production, traditional cooling methods, due to their cumbersome operation and uneven cooling effects, are gradually failing to meet the efficient and precise cooling requirements of modern industry. Therefore, there is an urgent need for a more integrated and automated cooling device to adapt to cooling operations under complex working conditions.

[0003] Currently, most cooling devices commonly used in industry adopt a fixed-installation nozzle structure. The cooling medium is transported to the nozzle through a straight pipe and then sprayed vertically onto the surface of the workpiece. These devices usually operate independently of the hoisting equipment. During cooling, the nozzle angle or workpiece position needs to be manually adjusted, making the operation process cumbersome. The working process is as follows: the coolant is stored in a fixed container, pressurized by a pump, and then transported to a nozzle at a fixed angle through a straight pipe. It is then sprayed onto the workpiece area to be cooled at a fixed flow rate and direction. Meanwhile, the hoisting equipment is only responsible for the up and down movement of the workpiece, and the cooling range and angle need to be repeatedly adjusted manually.

[0004] Existing technologies have several problems. Cooling operations require manual adjustment of the nozzle angle or workpiece position, resulting in complex procedures and low automation. Furthermore, the cooling range of the fixed nozzle is limited, making it difficult to cover the entire surface of the workpiece. This is especially problematic for complex-shaped or dynamically rotating workpieces, easily leading to cooling blind spots and localized overheating, which affects machining accuracy and equipment lifespan. Therefore, we propose a suspended spiral cooling device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a suspended spiral cooling device. By rotating the frame and linking the cooling nozzles to swing up and down, the cooling coverage area can be expanded, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hoisting spiral cooling device, comprising a frame, a rotating frame rotatably connected to the top wall of the frame, a hoisting assembly provided in the middle of the rotating frame, and further comprising a cooling assembly and a rotating assembly;

[0007] Cooling assembly: It includes a coolant tank, a spiral pipe, a hose and a cooling nozzle. The coolant tanks are respectively located on the left and right sides of the frame. The interior of each coolant tank is equipped with a spiral pipe. The lower end of each coolant tank is equipped with a hose. The hose is connected to the adjacent spiral pipe on the upper side. The lower end of each hose is equipped with a rotatable cooling nozzle.

[0008] Rotating components: These components are respectively located on the left and right sides of the frame. The rotating components are installed in conjunction with the adjacent cooling nozzles at the front and rear. The rotating components are set in conjunction with the rotating frame. The cooling nozzles swing up and down in linkage with the rotating frame, which can expand the cooling coverage area and improve uniformity and cooling efficiency.

[0009] Furthermore, a control switch group is provided on the right side of the frame, and the input end of the control switch group is electrically connected to an external power supply for stable control.

[0010] Furthermore, the cooling assembly also includes mounting plates and a rotating shaft. The front and rear inner walls of the frame are provided with symmetrically distributed mounting plates. The cooling nozzles are rotatably connected between two adjacent front and rear mounting plates via the rotating shaft, providing stable rotational support for the cooling nozzles.

[0011] Furthermore, the rotating assembly includes a driven gear, a rack plate, and a mounting bracket. The driven gear is fixedly connected to the rear end of the outer arc surface of the left rotating shaft and the front end of the outer arc surface of the right rotating shaft, respectively. The mounting bracket is respectively disposed on the upper surface of the mounting plate at the rear end of the left side and the upper surface of the mounting plate at the front end of the right side. The rack plate is slidably connected inside the mounting bracket, and the rack plate is meshed with the driven gear adjacent to the lower side, causing the cooling nozzle to swing up and down.

[0012] Furthermore, the rotating assembly also includes pins, connecting rods, drive rods, and connecting shafts. Pins are provided on the lower sides of the opposite inner ends of the rack plate, and connecting rods are rotatably connected to the outer arc surfaces of the pins. The lower side of the rotating frame is provided with symmetrically distributed drive rods, and the drive rods are rotatably connected to the adjacent connecting rods on the lower side through connecting rods, so as to facilitate synchronous rotation with the rotating frame.

[0013] Furthermore, a servo motor is mounted on the upper side of the frame. The output shaft of the servo motor is fixedly connected to the center of the upper end face of the rotating frame. The input end of the servo motor is electrically connected to the output end of the control switch group for stable driving.

[0014] Furthermore, the cooling assembly also includes a fan, which is installed on the upper side of the two coolant tanks respectively. The output port of the fan is fixedly connected to the upper end of the adjacent spiral pipe on the lower side, and the input end of the fan is electrically connected to the output end of the control switch group for induced airflow.

[0015] Furthermore, the hoisting assembly is an electric hoist, which is located in the middle of the rotating frame. The input end of the electric hoist is electrically connected to the output end of the control switch group for hoisting the mold.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This hoisting spiral cooling device has the following advantages:

[0017] When the rotating frame is driven by a servo motor to rotate 180 degrees in both directions, the drive rod on the lower side of the rotating frame pushes the rack plate to slide horizontally within the mounting frame through a linkage mechanism (connecting rod and pin). The meshing transmission between the rack plate and the driven gear drives the rotating shaft to rotate, which in turn causes the cooling nozzle to swing up and down around the rotating shaft. This linkage design can cover the cooling needs of different positions of the mold. Compared with the traditional fixed-angle cooling method, it significantly expands the spray range of the cooling medium, effectively avoids the problem of local overheating caused by uneven cooling on the surface of the mold, and improves the uniformity and comprehensiveness of the cooling operation.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This embodiment provides a technical solution: a hoisting spiral cooling device, including a frame 1, a control switch group 7 on the right side of the frame 1, the input end of the control switch group 7 being electrically connected to an external power source, a rotating frame 4 rotatably connected to the top wall of the frame 1, a servo motor 6 mounted on the upper side of the frame 1, the output shaft of the servo motor 6 being fixedly connected to the center of the upper end face of the rotating frame 4, the input end of the servo motor 6 being electrically connected to the output end of the control switch group 7, a hoisting assembly in the middle of the rotating frame 4, the hoisting assembly being an electric hoist 5, the electric hoist 5 being located in the middle of the rotating frame 4, the input end of the electric hoist 5 being electrically connected to the output end of the control switch group 7, and also including a cooling assembly 2 and a rotating assembly 3;

[0026] Cooling assembly 2 includes a coolant tank 21, a spiral pipe 22, a hose 23, and a cooling nozzle 24. The coolant tanks 21 are respectively located on the left and right sides of the frame 1 (each coolant tank 21 has a replenishment pipe at its upper end, through which coolant is poured into the coolant tank 21). Each coolant tank 21 has a spiral pipe 22 inside. Cooling assembly 2 also includes a fan 27, which is installed on the upper side of each of the two coolant tanks 21. The output port of each fan 27 is fixedly connected to the upper end of the adjacent spiral pipe 22 on the lower side. The input end of each fan 27 is electrically connected to the output end of the control switch group 7. Each coolant tank 21 has a hose 23 at its lower end, which is connected to the adjacent spiral pipe 22 on the upper side. 27 is started, and external air is forced into the spiral pipe 22. The spiral pipe 22 prolongs the residence time of the air in the coolant tank 21, enhancing the heat exchange efficiency between the air and the coolant in the coolant tank 21. The cooling medium is delivered to the cooling nozzle 24 through the hose 23. It is evenly sprayed onto the rotating mold surface as the nozzle swings. The up and down swing of the cooling nozzle 24 expands the cooling coverage area, avoids local overheating, and increases the heat exchange time between the air and the coolant. The lower end of the hose 23 is equipped with a rotatable cooling nozzle 24. The cooling assembly 2 also includes mounting plates 25 and a rotating shaft 26. The front and rear inner walls of the frame 1 are equipped with symmetrically distributed mounting plates 25. The cooling nozzles 24 are rotatably connected between two adjacent front and rear mounting plates 25 through the rotating shaft 26.

[0027] Rotating assembly 3: This assembly includes components respectively disposed on the left and right sides of the frame 1. Each rotating assembly 3 is installed in conjunction with adjacent cooling nozzles 24. The rotating assembly 3 includes a driven gear 31, a rack plate 32, and a mounting bracket 33. The driven gear 31 is fixedly connected to the rear end of the outer arc surface of the left rotating shaft 26 and the front end of the outer arc surface of the right rotating shaft 26. The mounting bracket 33 is disposed on the upper surface of the mounting plate 25 at the rear end of the left side and the upper surface of the mounting plate 25 at the front end of the right side. The internal components of each rack 32 are slidably connected to a rack plate 32, which meshes with the adjacent driven gear 31 on the lower side. (The mounting bracket 33 has a through hole in the middle, which is rotatably connected to the outer arc surface of the adjacent rotating shaft 26.) The rotating assembly 3 is configured to cooperate with the rotating frame 4. The rotating assembly 3 also includes a pin 34, a connecting rod 35, a drive rod 36, and a connecting shaft 37. The lower side of the opposite inner end of each rack plate 32 is provided with a pin 34, and the outer arc surface of each pin 34 is rotatably connected to a connecting rod 37. 5. The lower side of the rotating frame 4 is provided with symmetrically distributed drive rods 36. The drive rods 36 are all rotatably connected to the adjacent lower connecting rods 35 through connecting rods 35. After the control switch group 7 is connected to the external power supply, the electric hoist 5 descends to complete the hoisting and fixing of the mold. The servo motor 6 is started to drive the rotating frame 4 to rotate 180 degrees in both directions. The drive rods 36 on the lower side of the rotating frame 4 push the pin shaft 34 through the connecting rod 35, so that the rack plate 32 slides horizontally in the mounting frame 33. It meshes with the driven gear 31 to drive the rotating shaft 26 to rotate, thereby allowing the cooling nozzle 24 to swing up and down around the rotating shaft 26. At the same time, the fan 27 is started, which presses the cooling medium in the coolant tank 21 into the spiral pipe 22, and delivers it to the cooling nozzle 24 through the hose 23. The cooling nozzle 24 is sprayed onto the rotating surface of the mold as it swings. Every time the rotating frame 4 completes one forward and reverse rotation, the cooling nozzle 24 synchronously completes one swing cycle, realizing all-round cooling of the mold. After cooling is completed, the equipment is shut down, the electric hoist 5 descends to unload the mold, and the device is reset to wait for the next cycle.

[0028] The working principle of the hoisting spiral cooling device provided by this utility model is as follows: After the control switch group 7 is connected to the external power supply, the electric hoist 5 is started, and its hook descends to the position of the grinding mold to be cooled, completing the hoisting and fixing of the grinding mold. The electric hoist 5 can accurately control the hoisting height and position to adapt to grinding molds of different sizes. Then the electric hoist 5 lifts the grinding mold. The servo motor 6 is in the off state by default, the rotating frame 4 remains horizontal and stationary, and the cooling nozzle 24 is fixed between the mounting plates 25 through the rotating shaft 26, with the initial angle vertically downward (or adjusted according to the preset). The servo motor 6 is started by the control switch group 7, and its output shaft drives the rotating frame 4 to rotate 180 degrees in both directions. Then, the electric hoist 5 drives the grinding mold to rotate synchronously. When the rotating frame 4 rotates, the drive rod 36 on its lower side pushes the connecting rod 35 through the connecting shaft 37. The connecting rod 35 pulls or pushes the rack plate 32 to slide horizontally in the mounting frame 33 through the pin shaft 34. The rack plate 32 and the driven gear 3 1. Engagement drives the rotating shaft 26 to rotate, causing the cooling nozzle 24 to swing up and down around the rotating shaft 26. When the rotation direction of the rotating frame 4 changes, the drive rod 36 moves in the opposite direction, causing the rack plate 32 to slide in the opposite direction through the connecting rod 35. The swing direction of the cooling nozzle 24 changes accordingly, realizing periodic up and down swing. While the cooling nozzle 24 swings, the fan 27 starts, forcing external air into the spiral pipe 22. The spiral pipe 22 prolongs the residence time of the air in the coolant tank 21, enhancing the heat exchange efficiency between the air and the coolant in the coolant tank 21. The cooling medium is delivered to the cooling nozzle 24 through the hose 23 and sprayed evenly onto the rotating mold surface as the nozzle swings. The up and down swing of the cooling nozzle 24 expands the cooling coverage area and avoids local overheating. The spiral pipe 22 and the fan 27 work together to ensure that the cooling medium is output at a stable pressure. After the mold is cooled, the servo motor 6 and the fan 27 are turned off, and the electric hoist 5 descends to the designated position to unload the mold.

[0029] It is worth noting that the fan 27 disclosed in the above embodiments can be of the HTFC series, the electric hoist 5 can be of model CD1-5T-12M, the servo motor 6 can be of model MSMF042P1 U, and the control switch group 7 is provided with control buttons that correspond one-to-one with the fan 27, the electric hoist 5 and the servo motor 6 and are used to control their switching.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
