Description

Technical Field

[0001] This invention relates to the field of ice cone manufacturing technology, specifically to a stretching assembly process and equipment used in ice cone manufacturing. Background Technology

[0002] like Figure 1 The existing ice-making cylinders shown are composed of an outer shell 9 and an inner cylinder 10. The inner cylinder is inserted into the outer shell and then welded together. The spiral grooves on the outer wall of the inner cylinder and the inner wall of the outer shell are used to form a refrigerant flow channel. This processing method has high requirements for welding technology and is relatively difficult to process. It is easy for gas to cross between adjacent flow channels. In addition, welding rods need to be wrapped around the inner cylinder surface on both sides of the spiral grooves, which also increases the welding cost. Therefore, it is particularly important to design a stretching assembly process and equipment for ice-making cylinder manufacturing in order to solve the above problems. Summary of the Invention

[0003] To address the aforementioned problems, this invention presents a stretching assembly process and equipment for ice-making cone manufacturing. By stretching, the outer shell is contracted, thereby automatically and tightly adhering to the outer wall of the inner cylinder. This not only improves processing efficiency but also significantly reduces costs, thereby increasing practicality.

[0004] To solve the above-mentioned technical problems, the present invention provides a stretching assembly process for ice cone manufacturing, characterized by the following steps: S1: Visual inspection: Visually inspect the outer shell and inner cylinder of the ice maker to ensure that there are no defects on the surface; S2: Surface cleaning: Wipe the outer surface of the ice maker with a clean cloth; S3: Loading and positioning: The inner cylinder is inserted into the outer shell and placed uniformly on the support base plate of the stretching fixture. The ice cylinder to be stretched is positioned by the positioning groove on the support base plate. S4: Stretching Assembly: Start the drive hydraulic cylinder installed on the stretching fixture to complete the stretching assembly of the ice maker using the stretching fixture. S5: Material unloading inspection: Remove the ice cylinder that has been stretched and assembled in step S4 from the support base plate of the stretching fixture, and then send it into the real-time imaging system for imaging inspection. S6: Surface polishing: After the inspection in step S5 is completed without any problems, the surface of the ice cylinder is polished by a milling machine to remove the traces generated during the stretching process. After polishing, it is stored in the warehouse.

[0005] Furthermore, in step S2, a new wiping cloth is used after wiping every 50-60 outer casings.

[0006] Furthermore, in step S3, lubricating oil is applied to the stretching surface of the outer shell before the material is loaded and positioned.

[0007] Furthermore, the real-time imaging system in step S5 is a CCD inspection device. The image sensor in the CCD inspection device displays the assembly between the inner wall of the outer shell and the outer wall of the inner cylinder in the form of an image. During the inspection process, the ice-making cylinder is rotated, and the worker can intuitively observe whether the overall assembly after stretching meets the requirements.

[0008] The present invention also provides a stretching fixture for ice cone manufacturing, characterized in that it includes a supporting base plate, a stretching die assembly, a stretching die fixing plate, a transmission plate, and a mounting top plate. The mounting top plate is fixed above the supporting base plate by four supporting guide pillars located at the four corners of the bottom. The stretching die assembly is mounted on the stretching die fixing plate. The stretching die fixing plate has guide holes at positions relative to the four supporting guide pillars. A hydraulic cylinder assembly for stretching drive is fixed on the mounting top plate. The output shaft end of the hydraulic cylinder assembly passes through the mounting top plate and is connected to the transmission plate. The transmission plate is fixedly connected above the stretching die fixing plate by connecting pillars. The stretching die fixing plate slides up and down along the supporting guide pillars under the drive of the hydraulic cylinder assembly.

[0009] Furthermore, a U-shaped through groove is provided at the center of the supporting base plate, the front end of the U-shaped through groove is open, and a positioning groove matching the outer edge of the outer shell is also provided on the inner wall of the U-shaped through groove.

[0010] Furthermore, the stretching die assembly is composed of an annular upper seat, an annular lower seat, and a stretching head. The centers of the annular upper seat and the annular lower seat are on the same vertical line and connected as one unit. The stretching head is also annular in shape and is embedded in the lower end of the annular lower seat. The inner diameters of the annular lower seat and the annular upper seat above the stretching head are both larger than the inner diameter of the stretching head, and the outer diameter of the annular lower seat is smaller than the outer diameter of the annular upper seat.

[0011] Furthermore, the lower end of the inner ring of the stretching head is open and matches the chamfer at the upper end of the outer shell. Furthermore, a countersunk hole is provided at the center of the stretching die fixing plate, the annular upper seat is embedded and fixed in the upper end of the countersunk hole, and the lower end of the annular lower seat passes through the stretching die fixing plate along the countersunk hole.

[0012] Furthermore, the distance between the transmission plate and the stretching mold fixing plate is greater than the height of the ice-making cylinder outer shell.

[0013] With the above structure, the present invention has the following beneficial effects: This invention shrinks the outer shell by stretching, so that it automatically fits tightly against the outer wall of the inner cylinder. This not only improves processing efficiency but also greatly reduces costs, thus increasing practicality.

[0014] The tensioning fixture used in this invention is not only simple in structure and easy to manufacture, but also has the advantages of being convenient to use and highly efficient. Attached Figure Description

[0025] The present invention will be further described in detail below through specific embodiments.

[0026] This invention provides a stretching assembly process for ice cone manufacturing, specifically including the following steps: S1: Visual inspection: Visually inspect the outer shell and inner cylinder of the ice maker to ensure that there are no defects on the surface; S2: Surface cleaning: Wipe the outer surface of the ice maker with a clean cloth; S3: Loading and positioning: The inner cylinder is inserted into the outer shell and placed uniformly on the support base plate of the stretching fixture. The ice cylinder to be stretched is positioned by the positioning groove on the support base plate. S4: Stretching Assembly: Start the drive hydraulic cylinder installed on the stretching fixture to complete the stretching assembly of the ice maker using the stretching fixture. S5: Material unloading inspection: Remove the ice cylinder that has been stretched and assembled in step S4 from the support base plate of the stretching fixture, and then send it into the real-time imaging system for imaging inspection. S6: Surface polishing: After the inspection in step S5 is completed without any problems, the surface of the ice cylinder is polished by a milling machine to remove the traces generated during the stretching process. After polishing, it is stored in the warehouse.

[0027] This invention shrinks the outer shell by stretching, so that it automatically fits tightly against the outer wall of the inner cylinder. This not only improves processing efficiency but also greatly reduces costs, thus increasing practicality.

[0028] In step S2 above, replace the wiping cloth with a new one after wiping every 50-60 outer shells.

[0029] In step S3 above, lubricating oil is applied to the stretching surface of the outer shell before the material is loaded and positioned.

[0030] The real-time imaging system in step S5 above is a CCD inspection device. The image sensor in the CCD inspection device displays the assembly between the inner wall of the outer shell and the outer wall of the inner cylinder in the form of an image. During the inspection process, the ice cylinder is rotated, and the worker can intuitively observe whether the overall assembly after stretching meets the requirements.

[0031] like Figure 2 and Figure 3 The diagram illustrates a stretching fixture used in ice cylinder manufacturing, comprising a support base plate 1, a stretching die assembly, a stretching die fixing plate 2, a transmission plate 4, and a mounting top plate 3. The mounting top plate is fixed to the support base plate via four support guide posts 5 located at the four corners of the bottom. The stretching die assembly is mounted on the stretching die fixing plate, which has guide holes positioned relative to the four support guide posts. A hydraulic cylinder assembly for stretching is fixed to the mounting top plate, with its output shaft passing through the mounting top plate and connected to the transmission plate. The transmission plate is fixed to the top of the stretching die fixing plate via connecting posts 6. Driven by the hydraulic cylinder assembly, the stretching die fixing plate slides up and down along the support guide posts. The distance between the transmission plate and the stretching die fixing plate is greater than the height of the ice cylinder's outer shell. During operation, the ice cylinder to be stretched is placed on the support base plate, and then the hydraulic cylinder assembly is activated, using the stretching die fixing plate to press the stretching die assembly downwards, thus completing the stretching assembly of the ice cylinder. The tensioning fixture used in this invention is not only simple in structure and easy to manufacture, but also has the advantages of being convenient to use and highly efficient.

[0032] like Figure 2 The support base plate shown has a U-shaped through groove at its center, with the front end of the U-shaped through groove open. The inner wall of the U-shaped through groove also has a positioning groove 1-1 that matches the outer edge of the outer shell. During loading, the folded outer edge 9-1 of the outer shell is inserted into the support base plate along the positioning groove. This design allows for quick positioning of the ice-making cylinder with stretching. Furthermore, this structure allows the outer shell of the ice-making cylinder to automatically separate from the stretching mold assembly when the stretching mold assembly rises, increasing its practicality.

[0033] like Figure 4 and Figure 5 The stretching die assembly consists of an annular upper seat 7, an annular lower seat 11, and a stretching head 8. The centers of the annular upper seat and the annular lower seat are on the same vertical line and are connected as one unit. The stretching head is also annular in shape and is embedded in the lower end of the annular lower seat. The inner diameter of the annular lower seat and the annular upper seat above the stretching head is larger than the inner diameter of the stretching head, and the outer diameter of the annular lower seat is smaller than the outer diameter of the annular upper seat. The lower end of the inner ring of the stretching head is open and matches the chamfer of the upper end of the outer shell.

[0034] The aforementioned stretching die fixing plate has a countersunk hole at its center. The annular upper seat is embedded and fixed in the upper end of the countersunk hole, and the lower end of the annular lower seat passes through the stretching die fixing plate along the countersunk hole.
