Abstract
The utility model discloses a squaring mould for a big shifting-fork forging piece. The squaring mould comprises an upper mould and a lower mould; a lower end of the upper mould is provided with a punching head; an upper end of the lower mould is provided with a cavity which is matched with the punching head; and a material gathering groove is arranged below the cavity. In the traditional blank-forming, the squaring is carried out by using a flat mould, and subsequently, the upper mould is still a flat mould and the lower mould is a squaring mould with the material gathering groove. According to the squaring mould for the big shifting-fork forging piece, when the blank is squared, a material for the middle head of the blank can be guaranteed, and meanwhile, the materials for the fork parts of a shifting fork at two ends are squared and stretched; and the squaring mould for the big shifting-fork forging piece is a rapid and good blank-forming process.
Description
Technical field
The utility model relates to the die-forging forming technology that is applicable to big shift fork forging blank in the heavy type lorry transmission-gear box, specifically belongs to big shift fork forging with pressing Fang Mo.
Background technology
During blank-making technologies such as the pier that such shift fork is general as if employing is thick, pressure side, the pulling of pneumatic hammer two ends, pneumatic hammer open die forging operative employee is difficult to the size of control shift fork head blank.If it is few that the head blank stays, then the shift fork head is not fully filled and scraps during die forging; If the head blank stays many; Then shift fork prong part might lack material and is not fully filled and scraps; So having increased by one when pressure side, the thick back of pier, we gather hopper; Thereby guarantee just can gather the hopper moulding at 2-3 pressure side's occiput blank, thereby guarantee that whole shift fork forge piece blank reheating distribution is more even, die forging is accomplished smoothly.
The utility model content
The purpose of the utility model provides a kind of big shift fork forging with pressing Fang Mo, adopts flat-die pressures side during original base, after change patrix into and still be flat-die, counterdie is to be with the pressure Fang Mo that gathers hopper.To blank pressure side the time, the middle head materials of blank are guaranteed, simultaneously to the materials side of the pressure pulling of two ends shift fork fork portion, belong to a kind of faster and better blank-making technology again.
The technical scheme of the utility model is following:
Big shift fork forging includes upper die and lower die with pressing Fang Mo, and the lower end of patrix has drift, and the upper end of counterdie has the die cavity that is complementary with drift, and the below of die cavity is provided with gathers hopper.
The two ends of described patrix have rounded corner.
Adopt flat-die pressures side during the original base of the utility model, after change patrix into and still be flat-die, counterdie is to be with the pressure Fang Mo that gathers hopper.To blank pressure side the time, the middle head materials of blank are guaranteed, simultaneously to the materials side of the pressure pulling of two ends shift fork fork portion, belong to a kind of faster and better blank-making technology again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing, big shift fork forging includes patrix 1, counterdie 2 with pressing Fang Mo, and the lower end of patrix 1 has drift 3, and the upper end of counterdie 2 has the die cavity 4 that is complementary with drift, and the below of die cavity 4 is provided with gathers hopper 5, and the two ends of patrix have rounded corner 6.
Claims (2)
1. big shift fork forging includes upper die and lower die with pressing Fang Mo, and it is characterized in that: the lower end of patrix has drift, and the upper end of counterdie has the die cavity that is complementary with drift, and the below of die cavity is provided with gathers hopper.
2. use according to big shift fork forging according to claim 1 and press Fang Mo, it is characterized in that: the two ends of described patrix have rounded corner.
