Description

One-step forming stamping die for filter press transportation lifting hook

Technical Field

The utility model belongs to the technical field of cold stamping forming machines, and relates to a punch forming die for a lifting hook (for short, a transportation lifting hook) for loading and unloading a filter press.

Background

The cold stamping forming is a machining method with less or no cutting scraps, and is a part machining method with energy saving, low consumption and high efficiency. The cold-punching forming machine is matched with the punching die, and pressure is applied to the material at normal temperature to separate or generate plastic deformation so as to obtain a product with a certain shape and size; mainly comprises a stamping mechanism, a double-column rack and a control cabinet; the cold stamping forming machine and the one-time stamping forming lifting hook die are matched for use, so that a product is quickly formed, and labor force is liberated.

The filter press is a pressurized filtering device with multiple filter chambers operated intermittently, and consists of a machine base, a thrust plate, a pressing plate, a main beam, a pulling plate system, a hydraulic system, a filter plate and an electric control system, wherein most of all components of the filter press are steel parts, heavy and large in size, and can be conveniently transported only by installing a lifting hook; the existing lifting hook is complex in production process, can not be formed once after being bent and cut through two processes, and seriously hinders the improvement of the production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the processing degree of difficulty of current pressure filter transportation lifting hook, solving corresponding technical problem, providing a pressure filter transportation lifting hook stamping forming mould.

The utility model provides an innovation technical scheme that prior art problem adopted is: the press filter transportation lifting hook stamping forming die has the main points of the overall technical scheme that the innovative overall structure is compared with the prior art, and the press filter transportation lifting hook stamping forming die has the prominent substantive characteristics that: the round steel rod is placed on the stamping die and directly stamped to be formed in one step, so that two processes of bending and cutting are omitted, the production efficiency is improved, and the labor force is liberated.

Furthermore, the stamping die comprises an upper die and a lower die, the upper die is provided with an upper die connecting plate and a flat semicircular stamping knife, the upper die connecting plate is a thick steel plate and is connected with an upper die base and the flat semicircular stamping knife and is also provided with sharp side edges (at the edges of two sides of the connecting plate), when the upper die descends, the flat semicircular stamping knife stamps the steel rod into a U shape, the two side edges of the upper die connecting plate cut off the steel rod, and the length of the upper die connecting plate is equal to the length of the material bearing plate and the length of the transportation lifting hook; the diameter of the flat semicircular stamping knife is equal to that of the transportation lifting hook, the thickness of the stamping knife is certainly larger than that of the steel rod, the cutting edge of the stamping knife is ensured to completely cover the steel rod, and the stamping forming is carried out at one time; the material bearing plate of the lower die corresponds to the connecting plate of the upper die in position, the material bearing plate is designed on the lower die base and just corresponds to the punching knife and the connecting plate of the upper die, the shape of a groove formed in the central line of the material bearing plate is similar to that of a transportation lifting hook, linear grooves are symmetrically arranged on two sides of the material bearing plate, the linear grooves on the two sides are equal in size and identical in structure, the width of each groove is slightly larger than the diameter of the steel stick, the depth of each groove is slightly larger than the radius of the steel stick, and the steel stick is guaranteed to be placed on the material bearing plate stably and not to fall off; a flat U-shaped groove is dug in the center of the material bearing plate, the depth and the width of the groove are slightly larger than the radius of the outer ring of the transportation lifting hook and the diameter of the outer ring, so that smooth punching and blanking can be ensured, and the phenomenon that a punching knife flashes a knife edge and is hard to bump is avoided, so that the punching quality is influenced; the lifting hook is often impacted in the operation process and needs to be made of high-quality carbon steel with good toughness; from the descending stroke of the upper die punching cutter, the descending stroke of the punching cutter is certainly smaller than the depth of the U-shaped groove of the material bearing plate, one is convenient for manually taking a piece, and the other is capable of preventing the punching cutter from colliding with the material bearing plate to cause accidents.

The utility model provides a pressure filter transportation lifting hook one shot forming stamping die, the progress that is showing reduces manufacturing procedure, has improved production efficiency, has satisfied mass production's demand, reduces workman intensity of labour.
