Multi-station integrated hydraulic trimming die machine

Abstract

The invention provides a multi-station integrated hydraulic trimming die machine. The machine comprises a base, a machine table, a left mounting shell, a right mounting shell, a top mounting plate, asliding rod, a two-stage hydraulic oil cylinder, a machine table sliding block, a die assembly and grating sensors, wherein the machine table is mounted above the base, the left mounting shell and theright mounting shell are arranged on the left side and the right side of the machine table, the top mounting plate is arranged at the tops of the left mounting shell and the right mounting shell, thetwo-stage hydraulic oil cylinder is mounted at the top of the top mounting plate, a sliding rod is mounted between the top mounting plate and the machine table, the machine table sliding block is mounted on the sliding rod, the grating sensors are arranged on the front sides of the left mounting shell and the right mounting shell, the die assembly is divided into an upper-pressing and upper-ejection type structure and an upper-pressing and lower-ejection pass-type structure, a workpiece can be trimmed in two different modes, a male die is located below and a female die is located above when the upper-pressing and upper-ejection type structure is adopted, pressure borne by the workpiece can be effectively reduced, the descending distance of a first-stage hydraulic rod can be recorded and modulated through a displacement sensor, and it is ensured that the shear force is of a suitable magnitude.

Description

Technical field [0001] The invention relates to the field of stamping and trimming equipment, in particular to a multi-station integrated hydraulic trimming die machine. Background technique [0002] In the production process of metal casting parts or products, according to relevant quality and technical requirements, the burrs and risers of rough products with uneven edges must be trimmed. Normally, the burrs and risers of the rough products must be trimmed. The process requires multi-machine and multi-station combination linkages such as milling machines, grinding wheel machines, angle grinders, and straight grinders to complete. It is time-consuming and labor-intensive, requires a large investment in manpower and equipment, and has low production efficiency and high cost, and the products produced The quality is uneven. [0003] The burr cutting process of existing metal castings is often completed by a punching and trimming machine. This cutting method has high stability, good...

Problems solved by technology

[0004] However, the existing punching and trimming machines all adopt the mold setting method in which the die is on the bottom and the punch is on the top, and the hydraulic system of the punching and trimming machine adopts high-pressure shearing. This shearing method causes pressure on the workpiece It is very large, and it is easy to cause damage to the workpiece, resulting in an increase in the scrap rate and an increase in production costs. Moreover, the existing punching and trimming machine can only perform trimming operations on a single workpiece at a time, which is inefficient

[0005] Existing punching and trimming machines cannot perform one-time punching and cutting on the risers of castings, and subsequent grinding and cutting are required, which wastes production time and reduces production efficiency, and the thickness of the risers is relatively wide. There is a cutting tool that cannot cut off the riser at one time. If it is cut at one time, the workpiece will be scrapped due to excessive shearing

[0006] The die of the existing punching and trimming machine is a pass-through type, and the blanking port is set in the center of the machine table. After the workpiece is punched and sheared, it falls directly from the central blanking hole. However, the pass-through die cannot cut the burrs in the middle of the workpiece, which has great limitations. , so the setting of the central blanking hole is also more limited for punching and trimming machines
