In the figure, 1, a female die, 2, a positioning plate, 3, a male die, 4, a male die fixing plate, 5, a positioning pin, 6, a positioning adjusting screw, 7, a ring part, 31, a guide section and 32, a male die edge are arranged.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model provides a manual gear cutting universal mould of lopps part, its structure is shown as figure 1-figure 3, including die 1 and the terrace die 3 of relative upper and lower setting, die 1 is located terrace die 3 under, and die 1 has the die edge of a knife, and terrace die 3 has the terrace die edge of a knife 32 relative with the die edge of a knife, and 1 up end of die is connected with mobilizable, circular shape locating plate 2, and the position that locating plate 2 corresponds the die edge of a knife is provided with the breach.

Furthermore, the front end of the male die 3 is provided with a guide section 31 facing the die edge for die alignment before processing the ring-like parts. The guide part at the front end of the male die 3 is firstly guided into the female die cutter edge, so that the female die cutter edge and the male die cutter edge 32 are well matched, the gap is stable and the gear cutting burr is small in the gear cutting process of the male die 3 and the female die 1.

Still include punch holder 4, terrace die 3 can dismantle and connect in punch holder 4. More specifically, the punch 3 is pressed into the hole of the punch retainer 4 with a tight fit. For example, a hole may be formed in the punch retainer 4, and the punches 3 of different sizes may be replaceably engaged in the hole of the punch retainer 4.

The punch retainer 4 is connected with at least two positioning pins 5 relative to the end surface of the female die 1, and the female die is provided with through holes opposite to the at least two positioning pins 5. The positioning pin 5 is in sliding fit with the through hole in a small gap, and plays a role in guiding and roughly positioning the male die blade 32 and the female die blade. In this embodiment, two positioning pins 5 are provided.

Still include positioning adjustment screw 6, be equipped with the bar hole that link up on locating plate 2, positioning adjustment screw 6 passes bar jogged joint in the up end of die 1, and the tooth height requirement of different lopps parts can be satisfied through the position of this bar hole removal regulation locating plate 2. And two locating pins 5 also pass locating plate 2, are carved with aforementioned bar hole syntropy, the bar hole that link up in the position that corresponds to two locating pins 5 on locating plate 2.

During gear cutting, the positioning adjusting screw 6 can be loosened, and then the positioning plate 2 is moved and adjusted, so that the distance from the sharp corner of the notch of the excircle of the positioning plate 2 to the edge of the female die with the R edge is consistent with the size of the tooth height. Then the adjusting screw 6 is screwed, the ring part 7 is put into the end face of the female die 1, and the die is manually closed, so that the scored line is aligned with the knife edges at two sides of the male die 3. Meanwhile, a polyurethane stick rubber is placed in the middle between the male die fixing plate 4 and the upper end face of the female die 1, and the die sinking effect is achieved after the teeth are cut. Then, the upper end face of the male die fixing plate 4 and the lower end face of the female die 1 are clamped by a vice, so that the two positioning pins 5 and the male die 3 are gradually guided into corresponding holes and knife edges of the female die 1, and the tooth cutting action is completed. And then loosening the vice, opening the die under the action of the elastic force of the polyurethane rubber, and then manually rotating the ring-shaped part 7 to repeat the operation process to finish the tooth cutting process of the next tooth. Repeating the steps to finish the cycle process of gear cutting of the next ring part.
