Abstract
Description
Technical Field
[0001] This invention relates to the field of blow molding machine technology, and in particular to a method for processing a blow molding machine frame. Background Technology
[0002] Plastic bottles have important applications in the liquid packaging industry. Among them, the blow molding machine is the equipment used to manufacture plastic bottles. The core component of the blow molding machine is its frame, which supports the plastic bottle forming molds (composed of left, right, and bottom molds). These single-mold, single-cavity frames are assembled within the main frame and precisely positioned using an indexing plate. During high-speed operation, the frame must not only support the weight of the mold frame and molds but also withstand the workload. Therefore, the quality of the frame directly affects the stable operation, efficiency, and durability of the blow molding machine.
[0003] During the manufacturing process of the frame, because the frame is made of cast blanks with irregular shape and large differences in the distribution of casting allowance, and there is no relatively flat clamping reference surface, manual positioning is required repeatedly during the processing, resulting in low production efficiency of the frame.
[0004] Therefore, a method for processing the blow molding machine frame is needed to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a method for processing a blow molding machine frame, which can improve the processing efficiency of the frame.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] The processing method for the blow molding machine frame includes the following steps:
[0008] S1. Draw a baseline on the frame blank, and draw a first positioning point and a second positioning point on both sides of the frame blank.
[0009] S2. Place the machine frame blank on the adjusting support of the milling reference fixture, and adjust the adjusting support so that the reference line of the machine frame blank is horizontal.
[0010] S3. The fixed rod tip on the milling reference fixture abuts against the first positioning point, and the movable tip on the milling reference fixture abuts against the second positioning point, thereby fixing the frame blank on the milling reference fixture;
[0011] S4. Mill the first reference surface and machine the first process hole on the frame blank using machining equipment;
[0012] S5. Using the first reference surface and the first process hole for positioning, fix the frame blank on the roughing fixture, rough mill the frame blank, finish mill the second reference surface and process the second process hole;
[0013] S6. Using the second reference surface for positioning, the frame blank is fixed on the finishing fixture through the second process hole, and the frame blank is finished to complete the processing of the frame.
[0014] In some embodiments, in step S1, a first central crosshair is drawn on one side of the frame blank to determine the first positioning point, and a second central crosshair is drawn on the other side of the frame blank to determine the second positioning point.
[0015] In some embodiments, in step S2, a height gauge is used to adjust the adjusting support.
[0016] In some embodiments, the height gauge is disposed on the adjusting support.
[0017] In some embodiments, a plurality of height gauges are spaced apart on the adjusting support.
[0018] In some embodiments, in step S4, a bottom hole is machined on the end face of the frame blank.
[0019] In some embodiments, in step S5, fastening bolts are used to pass through the first process hole to fix the frame blank on the roughing fixture.
[0020] In some embodiments, in step S6, fastening bolts are used to pass through the second process hole to fix the frame blank onto the finishing fixture.
[0021] In some embodiments, a fixture mother plate is installed on the rotary table of all the processing equipment, the origin coordinates of the fixture mother plate are calculated, and the origin coordinates of the fixture mother plate are copied into the working coordinate system of the processing equipment.
[0022] In some embodiments, the cutting tools of the processing equipment are assembled and pre-adjusted before being put into use to ensure that the cutting tools meet the processing requirements.
[0023] The beneficial effects of this invention are:
[0024] The present invention provides a method for machining a blow molding machine frame. First, a baseline is drawn on the frame blank, and a first positioning point and a second positioning point are drawn on both sides of the frame blank. Then, the frame blank is placed on the adjusting support of a milling reference fixture, and the adjusting support is adjusted so that the baseline of the frame blank is horizontal. The fixed rod tip on the milling reference fixture abuts against the first positioning point, and the movable tip on the milling reference fixture abuts against the second positioning point, thus fixing the frame blank on the milling reference fixture. A first reference surface is milled on the frame blank using machining equipment, and a first process hole is machined. Using the first reference surface and the first process hole, the frame blank is positioned and fixed on a roughing fixture, and a second reference surface and a second process hole are machined. The frame blank is positioned and fixed on a finishing fixture using the second reference surface and the second process hole. Finally, the frame blank is finished, completing the machining of the frame. By designing the processing steps in the above manner, the frame blank is accurately positioned using the datum line, the first positioning point, and the second positioning point. Then, the first datum surface and the first process hole are machined. The second datum surface and the second process hole are machined using the first datum surface and the first process hole. The frame blank is then precision machined, which ensures the machining accuracy. Moreover, each process has accurate positioning, eliminating the need for repeated adjustments to the positioning position and improving the machining efficiency of the frame.

For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.
[0030] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.
[0031] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.
[0032] In the process of machining the frame of a blow molding machine, in order to improve the machining efficiency of the frame, such as... Figure 1 As shown, the present invention provides a method for processing a blow molding machine frame. The method for processing the blow molding machine frame includes the following steps:
[0033] S1. Draw a baseline on the frame blank, and draw the first positioning point and the second positioning point on both sides of the frame blank.
[0034] S2. Place the machine frame blank on the adjusting support of the milling reference fixture, and adjust the adjusting support so that the reference line of the machine frame blank is horizontal.
[0035] S3. The fixed rod center on the milling reference fixture abuts against the first positioning point, and the movable center on the milling reference fixture abuts against the second positioning point, thus fixing the machine frame blank on the milling reference fixture.
[0036] S4. Use machining equipment to mill the first reference surface of the frame blank and machine the first process hole;
[0037] S5. Using the first reference surface and the first process hole for positioning, fix the frame blank on the roughing fixture, rough mill the frame blank, finish mill the second reference surface and machine the second process hole;
[0038] S6. Using the second reference plane for positioning, the frame blank is fixed on the finishing fixture through the second process hole, and the frame blank is finished to complete the machining of the frame.
[0039] By designing the processing steps in the above manner, the frame blank is accurately positioned using the datum line, the first positioning point, and the second positioning point. Then, the first datum surface and the first process hole are machined. The second datum surface and the second process hole are machined using the first datum surface and the first process hole. The frame blank is then precision machined, which ensures the machining accuracy. Moreover, each process has accurate positioning, eliminating the need for repeated adjustments to the positioning position and improving the machining efficiency of the frame.
[0040] In some embodiments, in step S1, a first central crosshair is drawn on one side of the frame blank to determine a first positioning point, and a second central crosshair is drawn on the other side of the frame blank to determine a second positioning point. This method facilitates the fitter in machining and marking the first and second positioning points on the frame blank.
[0041] In some embodiments, in step S2, a height gauge is used to adjust the adjustable support. By using a height gauge for measurement, it can be ensured that the baseline remains horizontal, thereby facilitating the adjustment of the adjustable support and ensuring that the final support blank is in a horizontal state during processing.
[0042] In some embodiments, a height gauge is mounted on the adjusting support. By integrating the height gauge into the adjusting support, there is no need to locate it on-site during the fixing of the support blank, saving time spent adjusting the adjusting support and thus improving processing efficiency.
[0043] In some embodiments, multiple height gauges are spaced apart on the adjustment support. By setting multiple height gauges, it is convenient to measure different positions of the support blank, thereby quickly determining the levelness of the baseline.
[0044] In some embodiments, in step S4, a bottom hole is machined on the end face of the frame blank. The bottom hole is machined simultaneously with the first process hole and the first reference surface, achieving the machining of the first process hole, the first reference surface, and the bottom hole in a single clamping and positioning operation. This avoids repeated clamping and positioning, thus ensuring machining efficiency and eliminating errors caused by repeated positioning. In this embodiment, the machining equipment is a machining center, which can simultaneously complete milling, drilling, and turning operations.
[0045] In some embodiments, in step S5, fastening bolts are passed through the first process hole to fix the machine frame blank onto the roughing fixture. This method ensures the machine frame blank is stably fixed on the roughing fixture, preventing it from shaking during subsequent processing.
[0046] In some embodiments, in step S6, fastening bolts are passed through the second process hole to fix the frame blank onto the finishing fixture. This method ensures the frame blank is stably fixed on the finishing fixture, preventing it from shaking during subsequent processing.
[0047] In some embodiments, a fixture mother plate is installed on the rotary table of all processing equipment, the origin coordinates of the fixture mother plate are calculated, and the origin coordinates of the fixture mother plate are copied into the working coordinate system of the processing equipment. By setting the fixture mother plate, since the position of the fixture mother plate relative to the rotary table of the processing equipment is fixed, after the fixture holding the machine frame blank is set on the fixture mother plate, processing can be performed without repeated positioning. Through the above method, processing efficiency can be further improved.
[0048] In some embodiments, the cutting tools of the machining equipment are assembled and pre-adjusted before use to ensure that the tools meet the machining requirements. Specifically, necessary tool machining parameters such as tool compensation and tool deviation are obtained. Sufficient tools are prepared in the tool magazine based on the standard tool life and 24-hour machining time. Simultaneously, the program length is adjusted according to the actual tool machining time and standard tool life to ensure that machining is completed within the tool life.
[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
