Abstract

The invention relates to a four-hammerhead mechanical precision forging machine. The invention provides a four-hammerhead mechanical precision forging machine which is superior in performance, simple in structure and low in manufacturing costs. The four-hammerhead mechanical precision forging machine is characterized in that firstly, workpiece size adjusting oil cylinders are connected to a rack slidingly; pistons are installed in the workpiece size adjusting oil cylinders; the workpiece size adjusting oil cylinders are fixedly connected with connecting rods; the pistons are fixedly connected with hammer rods and hammerheads; secondly, a drive motor is a common motor. The four-hammerhead mechanical precision forging machine has the advantages that an eccentric sleeve and a mechanical adjusting mechanism do not need to be arranged, so the structure is simple, and the manufacture cost is low and is lower by 70% than that of the traditional four-hammerhead mechanical precision forging machine.

Description

Four tup machinery precise forging machine
Technical field:
The present invention relates to a kind of four tup machinery precise forging machine.
Background technology:
At present the too complicated manufacturing cost of four tups machinery precise forging machine structures of various countries is high especially, and China was hundred million yuans of 1-3.5 from the price of four tups machinery precise forging machine of European import such as nearly ten years.This makes many enterprises of China originally should use precise forging machine to forge the enterprise of its product, as produced the steel mill of steel alloy and the tools factory of various places, but have to drop owing to cannot afford, and has so just seriously affected the industrial development of China.
Summary of the invention:
The four tup machinery precise forging machine that the object of this invention is to provide a kind of superior performance, low cost of manufacture simple in structure make China should use the enterprise of precise forging machine all to can use.
Content of the present invention is achieved in that one is the workpiece size adjustment oil cylinder (5) that is being slidably connected in frame (1), workpiece size is adjusted (5) in oil cylinder piston (6) is housed, workpiece size is adjusted (5) in oil cylinder and is fixedly connected with connecting rod (4), piston (6) is fixedly connected with hammer stem (7) and tup (8), and piston (6) is adjusted oil cylinder (5) with workpiece size and is slidably connected, is fixedly connected with hammer stem (7).The 2nd, drive motor (12) is common threephase motor.Little 45 degree bevel gears (9) are fixedly connected with drive motor (10).Drive motor (10) is fixedly connected with frame (1).
Advantage of the present invention is that eccentric bushing and mechanical Tiao Chi mechanism needn't be set, so simple in structure, manufacturing cost is also low by 70% than four traditional tups machinery precise forging machine
Brief description of the drawings:
Fig. 1 is structural representation of the present invention, and Fig. 2 is hydraulic principle figure of the present invention.Fig. 3 is tup position and the drafts graph of a relation of tup to workpiece, and the two-dot chain line in Fig. 3 represents that tup advances after 2E stroke and enters the position after workpiece.
Detailed description of the invention:
With reference to accompanying drawing, concrete structure of the present invention, hydraulic principle and the course of work are described.In Fig. 1, express each four tups machinery precise forging machine required four groups of striking mechanisms, each group striking mechanism is to be all the flywheel (2) of 45 degree bevel gears by periphery, eccentric shaft (3), piston (6) connecting rod (4), hammer stem (7), tup (8), workpiece size is adjusted the compositions such as oil cylinder (5), periphery is that the pinion (9) of 45 degree bevel gears is fixedly connected with drive motor (10) flywheel (2) that the pinion that periphery is 45 degree bevel gears (9) is 45 degree bevel gears with periphery and engages, workpiece size is adjusted oil cylinder (5) and is slidably connected with frame (1).Fig. 2 is hydraulic principle figure of the present invention, on the oil-out of oil pump (17), be connected to check valve (18), Pressure gauge (19), overflow valve (20), three-position four-way valve (13), two actuator ports of three-position four-way valve (13) join with two logical hydraulic fluid ports (9) and (10) of workpiece size adjustment oil cylinder (5) respectively, lead on the oil circuit of logical hydraulic fluid port (10) and be connected in series digital flow control valve (16), on hydraulic fluid port (9), be also connected to hydraulic pressure accumulator (21) workpiece size adjust oil cylinder (5) rodless cavity on be connected to pressure switch (14) and load releasing valve (15).
The course of work:
First to drive motors (10) and oil pump (17) energising, and give after three-position four-way valve (13 energising) energising because eccentric shaft of four groups of striking mechanisms of effect of each 45 degree bevel gear can be simultaneously by predefined synchronization rotation, and the eccentric shaft eccentric shaft of often going around will drive workpiece size to adjust oil cylinder (5) by connecting rod (4) hydraulic oil in its rodless cavity to be compressed and promote piston (6) and advance, the eccentric shaft piston (6) of often going around has the advance amount (E is eccentric shaft offset) of a 2E, because connecting rod is to be fixedly connected with tup, so piston (6) will make tup hit workpiece when advancing, if tup flat side of a hammer before strike is M with forging the distance at center, the drafts S=2E-(M-R) of tup to workpiece as shown in Figure 3 after hitting, after so each drafts S hitting determines, the distance M=2E-S+R specific works program of the flat side of a hammer and the centre of percussion:
Four tup machinery precise forging machine specific works programs have four steps: the one, adjust adjusted size tup position by preliminary election aperture, and the 2nd, hit continuously by the drafts of preliminary election, the 3rd, measure into hammer by the hammer that enters of preliminary election, the 4th, overload protection.
The one, by preliminary election aperture adjusted size tup position:
If outer piston and the outer end inner wall of adjusting oil cylinder (5) with workpiece size while contact tup outside and forging center apart from injecting Q1=(M-N) S (formula S is workpiece size adjustment oil cylinder (5) effective area) in workpiece size is adjusted the rodless cavity of oil cylinder (5) for N, then, tup outside and forging center apart from being M, it is that energising makes hydraulic oil that oil pump (17) pumps lead to actuator port of logical hydraulic fluid port (10) by it and to select flow be that the digital flow control valve (16) of Q1 is to having injected the hydraulic oil that flow is Q1 in the rodless cavity of workpiece size adjustment oil cylinder (5) through giving to three-position four-way valve (13) that rodless cavity from oil cylinder (5) to workpiece size that adjust injects the process of Q1.
The 2nd, hit continuously by the drafts S of preliminary election. adjust after M eccentric shaft by M=S-(2E+R) and often turn around and will on workpiece (22), have a drafts S.
The 3rd, measure into hammer by the hammer that enters of preliminary election: the hammer amount of entering of establishing choosing is H, enter to hammer into shape number of times and be n and adjust M value by drafts S=H/n and then hit continuously n each tup by the second work step and obtain into hammer amount H.
The 4th, overload protection: the hitting power while strike if actual exceedes predetermined value, the oil pressure of oil pocket (15) also can exceed predetermined value with workpiece size adjust normally opened contact in the pressure switch (17) that the rodless cavity of oil cylinder (5) connects connect make load releasing valve (18) thus off-load at once reaches safeguard protection effect.
