Description
Technical Field
[0001] The utility model relates to the technical field of forklift production, in particular to a V-process casting line film processing device for producing forklift counterweights. Background Art
[0002] Both V-process casting and lost foam casting use vacuum forming, but there are significant differences in their process flows. V-process casting gets its name from the first letter "V" of the English word Vacuum (vacuum). The biggest advantage that distinguishes it from traditional sand casting is that it does not use adhesives. V-process casting uses a plastic film to seal the sand box, and relies on a vacuum pumping system to extract the air inside the mold. There is a pressure difference between the inside and outside of the mold, which makes the dry sand compact and form the required cavity. After core setting, mold closing, and pouring, vacuum is applied to solidify the casting. The negative pressure is released, and the molding sand collapses to obtain the casting. Most V-process casting lines need to process the film before use.
[0003] However, the existing technology still has the following problems:
[0004] Firstly, when the V-process casting line film processing device of the existing technology produces forklift counterweights, most of the V-process casting line film processing devices cannot unwind the film well, resulting in a situation where it is easy to be unable to fit due to the inconsistent width of the film during the unwinding process of the V-process casting line film processing device.
[0005] Secondly, when the V-process casting line film processing device of the existing technology produces forklift counterweights, most of the V-process casting line film processing devices cannot cut the film well, resulting in the film being easily cut obliquely or damaged during the cutting process of the V-process casting line film processing device, thus resulting in poor cutting effect of the V-process casting line film processing device.
[0006] In view of the above problems, the inventor proposes a V-process casting line film processing device for producing forklift counterweights to solve the above problems. Content of the Utility Model
[0007] In order to solve the problems that most of the V-process casting line film processing devices cannot unwind the film well and most of the V-process casting line film processing devices cannot cut the film well; the purpose of the utility model is to provide a V-process casting line film processing device for producing forklift counterweights.
[0008] To solve the above technical problems, the present utility model adopts the following technical solutions: A V-process casting line film processing device for producing forklift counterweights, including a chassis. A cutting mechanism is fixedly provided at the upper end of the chassis for cutting the film.
