A rapid hot forging process for forklift separation fork

Abstract

The invention discloses a rapid hot forging forming process of a forklift release fork. The hot forging forming process can quickly produce a forklift release fork with excellent performance, and can be formed in one step, saving labor and production costs and improving production efficiency; the hot forging forming process By using hot forging equipment to forge the separation fork of the forklift, the hot forging equipment extrudes the heated raw steel through the extrusion between the shaping plate, the lower forming die and the load-bearing base to obtain the semi-finished product of the separation fork of the forklift. The automatic forming process is realized, the lower forming die is connected through the support mechanism, and the lower forming die is lifted, so that the semi-finished product of the forklift separation fork is placed on the top of the load-bearing base, and the semi-finished product of the forklift separation fork is pushed to the plate chain through the operation of the unloading cylinder. On the conveyor, the process of automatic unloading is completed; the equipment has a simple structure, and one piece of equipment can complete the forging process, and the degree of automation is high, which effectively improves the production efficiency.

Description

Technical field [0001] The present invention relates to the field of production of the forklift parts, and more particularly to a fast thermal forged process of a forklift separation fork. Background technique [0002] Industrial handling vehicles are widely used in port, station, airport, vendum, factory workshop, warehouse, circulation center and distribution center, etc. In the cabin, carriages and containers, handling, handling operation, is tray transport, container transportation An indispensable device, where the forklift plays a very important role in the logistics system of the enterprise, which is the main force in the material handling equipment, but the existing forklift separation is easy to show defects such as surface cracks, surface roughness and trenches. [0003] Hot forging is the forged forming process that heats the forging blank to a certain temperature, including free forging, fetal mold wying and die forging, and die forging uses the blowing force or press...

Problems solved by technology

[0006] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a rapid hot forging process for the separation fork of a forklift: (1) by heating the raw steel of the separation fork of the forklift in stages, the raw steel of the separation fork of the forklift is progressively During the process, stable processing performance is gradually formed, avoiding the instability of material properties caused by instantaneous high temperature, unstable grain size and shape of processed products, and even defects such as surface cracks, surface roughness and grooves, which solves the existing problems Some forklift separation forks are prone to defects such as surface cracks, rough surfaces, and grooves; (2) Forge the forklift separation fork by using hot forging forming equipment, and place the heated raw steel in the inner cavity of the lower forming die In the process, the piston connecting rod of the transport hydraulic cylinder shrinks and pulls the sliding base to slide in the first combination slide rail and the second combination slide rail until the sliding base touches the limit plate, and the forging hydraulic cylinder extends to push the mounting seat and upper hot forging The height of the die head is lowered, and the guide plate is inserted into the guide groove for guidance, which drives the shaping plate to extend into the inner cavity of the lower forming die head. Under the interaction of the heated raw steel, the heated raw steel is forged and formed, and the semi-finished product of the forklift separation fork is obtained. The C-shaped fork plate is pushed forward through the extension of the support cylinder, and the C-shaped fork plates on both sides are respectively extended to both sides of the lower forming die head. In the fork groove of the fork, the forging hydraulic cylinder shrinks, and the lower forming die head is driven up by the support mechanism, and the lower forming die head leaves the top of the load-bearing base. Push the semi-finished product of the forklift separation fork to move on the top of the load-bearing base, pass through the transfer plate and drop onto the plate chain conveyor, and then transport the semi-finished product of the forklift separation fork to the bending machine and the drilling machine for drilling through the operation of the plate chain conveyor, and then put it into cold water Cooling and oxygen isolation to obtain the finished forklift separation fork, which solves the problems of large number of machines, high cost of use, large space occupation, complicated blanking process and low production efficiency in the existing hot forging process
