Description

Technical Field

[0001] The utility model relates to the field of air-conditioning equipment, in particular to a manufacturing tool for air-conditioning clamp parts. Background Art

[0002] Air conditioning clamp parts are usually used in the installation of central air conditioning pipes to fix the pipes. Clamp parts are generally formed by stamping sheet metal parts and then bending them. Traditionally, they are produced by open molds, and at least 3 stamping dies are required to complete the complete processing of a part. For some special models of air conditioners, corresponding air conditioning clamps are required. In this case, there are very few orders for air conditioning clamps. If the open mold production method is adopted, the manufacturing cost of the parts will be too high. Therefore, it is necessary to study a tool suitable for small-batch production of air conditioning clamp parts. Utility Model Content

[0003] In order to overcome the disadvantages of the existing method of producing air conditioner clamp parts by using open molds, which leads to high costs, the technical problem to be solved by the utility model is to provide a low-cost production tool for air conditioner clamp parts.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not for the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0019] like Figure 1-5As shown, the utility model is a tool for making air conditioner clamp parts, including a profiling mold 1, the cross-section of the profiling mold 1 is formed by a 3 / 4 arc and two right-angled sides tangent to the ends of the 3 / 4 arc, a support seat 2 is provided at the intersection of the two right-angled sides, the support seat 2 includes a positioning plate 21 and a bottom plate 22, the lower surface of the positioning plate 21 is flush with the surface where one of the right-angled sides is located, the positioning plate 21 is provided with a positioning hole 23, the bottom plate 22 is provided with a positioning groove 24 corresponding to the positioning hole 23, and also includes a positioning rod 3, the lower end of the positioning rod 3 passes through the positioning hole 23 and is inserted into the positioning groove 24.

[0020] The profiling die 1 can be made of metal or plastic and other materials, and can be machined or injection molded. The width of the profiling die 1 is slightly larger than the width of the clamp part, so that the sheet metal 5 can be bent along the shape of the profiling die 1. The sheet metal 5 is used to make the clamp part, and is stamped according to the unfolded size of the clamp part, such as Figure 5 As shown, in order to be able to be manually bent, the thickness of the sheet metal 5 is preferably controlled between 0.4-1 mm, and the thickness of the common clamp parts is also within this range. The spacing between the positioning plate 21 and the bottom plate 22 can be slightly larger than the thickness of the sheet metal 5. The two sides of the positioning plate 21 and the bottom plate 22 should be open structures to facilitate the removal of the clamp parts after subsequent molding. The outer diameter of the positioning rod 3 should be the same as the aperture of the mounting hole 51 on the sheet metal 5 to ensure the positioning effect of the positioning rod 3 on the two ends of the sheet metal 5.

[0021] The use process of the utility model is as follows: first, the lower end of the sheet metal 5 is placed between the bottom plate 22 and the positioning plate 21, so that the mounting hole 51 on the sheet metal 5 is aligned with the positioning hole 23, and then the positioning rod 3 is inserted along the positioning hole 23, so that the lower end of the positioning rod 3 passes through the mounting hole 51 and enters the positioning groove 24, and the lower end of the sheet metal 5 is fixed, and then the sheet metal 5 is bent along the shape of the profiling mold 1, and when the upper end of the sheet metal 5 returns to one side of the support seat 2, the mounting hole 51 at the upper end of the sheet metal 5 is inserted into the upper end of the positioning rod 3, as shown in FIG. Figure 2 As shown, the sheet metal 5 is then pressed down along the positioning rod 3 by hand or other tools to make the sheet metal 5 abut against the positioning plate 21, thereby completing the production of the clamp part. Figure 1 Finally, the positioning rod 3 is taken out, and the clamp part is taken out from the side. The manufacturing tool of the present application can ensure that the mounting holes 51 at both ends of the sheet metal 5 can be aligned after bending, so as to facilitate the subsequent insertion of bolts to tighten the clamp part.

[0022] According to the change of the end position of the sheet metal 5 when it is pressed down and deformed, the present application sets the lower half of the positioning rod 3 as a straight segment, and the upper half as an arc segment that bends away from the profiling die. In this way, the sheet metal 5 can be better inserted into the positioning rod 3 before pressing down, and during the pressing process, it can be ensured that the end of the sheet metal 5 is always in a tensioned state, and the sheet metal 5 will not be deformed additionally.

[0023] In order to ensure that the positioning rod 3 does not rotate when pressing down the sheet metal 5, the positioning groove 24 can be set as a square groove, and the lower end of the positioning rod 3 is a square column matching the square groove, thereby preventing the positioning rod 3 from rotating.

[0024] Some clamp parts are relatively wide and need to be connected with two bolts. To facilitate positioning, the positioning holes 23 and positioning grooves 24 each include two, and each positioning hole 23 is provided with a positioning rod 3.

[0025] Further, such as Figure 4 As shown, one end of the profiling die 1 is provided with a support column 11, and the profiling die 1 is clamped on the vise 4 through the support column 11. Of course, the profiling die 1 can also be fixed to other structures by welding, bolt connection, etc. By fixing the profiling die 1, the labor intensity of the workers can be reduced and the molding quality of the clamp parts can be ensured.

[0026] The utility model sets a profiling die 1 with the same shape as the clamp part, and uses a support seat 2 and a positioning rod 3 to fix and position the end of the sheet metal 5, so that the sheet metal 5 is bent along the outer surface of the profiling die 1 to form an air conditioner clamp part. The entire tool has a simple structure and low cost, and can realize the flexible production of small and medium batches of clamp parts, solving the manufacturing problem that clamp parts must be produced and processed by opening a stamping die, and has good practicality and application value.
