Rapid hot forging forming process of forklift release fork

Abstract

The invention discloses a rapid hot forging forming process of a forklift release fork. According to the hot forging forming process, the forklift release fork with excellent performance is rapidly manufactured, one-step forming is achieved, the labor cost and the production cost are saved, and the production efficiency is improved. According to the hot forging forming process, the forklift release fork is forged through hot forging forming equipment, the hot forging forming equipment conducts extrusion forming on heated raw material steel through extrusion among a shaping plate, lower formingdie heads and a bearing base, a forklift release fork semi-finished product is obtained, the automatic forming process is achieved, the lower forming die heads are connected through a supporting mechanism, and the lower forming die heads are lifted, so that the forklift release fork semi finished product is placed on the top of the bearing base, the forklift release fork semi finished product ispushed onto a plate chain conveyor through operation of a discharging air cylinder, and the automatic discharging process is completed; and the equipment is simple in structure, the forging process can be completed through one piece of equipment, the automation degree is high, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the production field of forklift parts, in particular to a rapid hot forging forming process of a separation fork of a forklift. Background technique [0002] Industrial handling vehicles are widely used in ports, stations, airports, freight yards, factory workshops, warehouses, distribution centers and distribution centers, etc., for loading, unloading and handling of pallet goods in cabins, carriages and containers, which is a must in pallet transportation and container transportation. Indispensable equipment, among them, forklifts play a very important role in the logistics system of enterprises and are the main force in material handling equipment, but the existing forklift separation forks are prone to defects such as surface cracks, rough surfaces and grooves. [0003] Hot forging is a forging forming process that is carried out after heating the forging billet to a certain temperature, including free forging, tire die fo...

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
