Abstract

The utility model discloses a double-end open power press with a fixed bed, in the technical scheme, a power press body is welded with a work bench into a whole body through steel plates, sliding blocks are arranged on the power press body and do reciprocating movement in a guideway, a square head screw is arranged at the side of the power press body, and an operational key connected with a crankshaft and a middle sleeve fixed with a flywheel are arranged in the flywheel hole at the upper part of the power press body; the sliding blocks are connected with ball head screws through connection rods and make the crankshaft do reciprocating movement; and an eccentric band brake is installed at the upper part of the power press body. The utility model has simple structure, the rotational motion of the crankshaft can make the two sliding blocks complete synchronous operation or separate operation according to the production requirements, so the work load of a pressing production process is reduced, the work intensity is greatly reduced, and the production efficiency is improved; and the utility model can be used for general presses pressed by sheets, and is applicable to sheet punching, blanking, trimming, bending, front stretching and other stamping technologies.

Description

A kind of double end open type power press with fixed bed

Technical field

The utility model relates to a kind of forcing press, relates in particular to a kind of double end open type power press with fixed bed.

Background technology

In the industry-by-industry at home, for enhancing productivity, various forcing presses are used widely.As in the refrigerator manufacturing industry, extensive use forcing press produce various parts.Using at present wider at home be single head open type power press with fixed bed, and it mainly relies on motor as power, by belt transmission, utilizes the crank-driven connecting rod to drive single slide block and moves back and forth and finish punching press and move; Existing its structure of single head open type power press with fixed bed mainly comprises fuselage, clutch, slide block, brake and executor etc., but the each motion of the slide block of this open type power press with fixed bed can only be finished single action, all very inconvenient when high for the dimensional requirement precision between in enormous quantities, porous and each hole like this, work to workpiece location and operator has all brought a lot of inconvenience, has also had a strong impact on the production efficiency and the quality of production simultaneously.In addition, because the limitation of 26S Proteasome Structure and Function own,, must substitute by forcing press more complete by function, that efficient is higher, larger at present and all seriously restricted the large-scale application of power press with fixed bed in the future in every profession and trade.

The utility model content

At above defective, the purpose of this utility model provides a kind of double end open type power press with fixed bed, the production of, porous in enormous quantities to realize, reduces the workload of production process, and guarantees the dimension precision requirement between each hole.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of double end open type power press with fixed bed, comprise that fuselage is welded into one by steel plate and workbench, slide block is arranged on the fuselage and is reciprocating in its guide rail, described fuselage side is provided with square head screw, and a job key that is connected with bent axle and a middle cover of fixing with flywheel are housed in the flywheel hole of back; Described slide block is connected with ball screw by connecting rod and makes bent axle be set to move back and forth; Back is equipped with eccentric band brake.

The beneficial effect of double end open type power press with fixed bed described in the utility model is: simple in structure, the rotatablely moving of bent axle can make two slide blocks finish and work simultaneously or work independently according to producing needs, reduced the workload of punching production process, greatly reduce working strength, improved production efficiency; Can be used for the universal forcing press of sheet-metal press working, be applicable to Sheet Metal Forming Technologies such as plate punching, blanking, side cut, bending, preceding stretching.

The specific embodiment

Shown in Fig. 1-5, double end open type power press with fixed bed described in the utility model, comprise that fuselage 1 adopts steel plate and workbench 2 to be welded into one, slide block 3 is arranged on the fuselage and is reciprocating in its guide rail, by the gap of fuselage 1 side square head screw adjusting guide rail and slide block 3; Body adopts the rigidity material, regulate on the lathe bed beat excellent screw position the time, pusher is moved betide slide block 3 strokes near upper dead center position; A job key 6 that is connected with bent axle 5 and a middle cover 7 of fixing with flywheel 4 are housed in flywheel 4 holes on fuselage 1 top, two ends, the left and right sides in its hole respectively are pressed into a copper bush, when bent axle 5 quits work, flywheel 4 freely put revolution interior, the key tail of described job key 6 is arranged at the bent axle 5 axle journal exposed uncovered positions places between fuselage 1 and the flywheel 4, have three grooves that can embed job key 6 on the cover 7 in described, the middle cover 7 outside tension springs 9 of installing; When not working, operation of cam 8 push and block key tails, make job key 6 leave in cover 7 grooves, then flywheel 4 idle running and bent axle 5 stops operating; Stepped on and changeed certain angle and after leaving the key tail, job key 6 has turned round an angle under the effect of tension spring 9 when handling cam 8, during job key 6 embeds behind cover 7 grooves, then flywheel 4 drives bent axles 5 and rotates, and forcing press is started working; Slide block 3 is connected with ball screw 11 by connecting rod 10 and rotatablely moving of bent axle 5 is changed into reciprocating motion, ball screw 11 lower ends are provided with the ball-type seat 12 of slide block, be provided with one in ball-type seat 12 bottoms and press the formula safety box that collapses, when forcing press overloads, protector is collapsed by pressure, thereby the parts that guarantee forcing press are not damaged, and must change safety box and could work this moment.When two slide blocks 3 of needs are worked simultaneously, regulate ball screw 11 and make ball-type seat 12 contour getting final product, during if will work independently, regulate ball screw 11 make needs the ball-type of work seat 12 highly to reduce, stagger in the position, shut height is inconsistent, do not interfere during work and get final product, the while is necessary proof strength and machining accuracy when machining crankshafts 5; Fuselage 1 top is equipped with eccentric band brake 13, and its effect is the inertia that overcomes moving components such as bent axle 5 and slide block 3, behind throw-out-of clutch, makes bent axle 5 stop at top dead-centre, the star nut on the tension force adjustable size joint pull bar of brake band.According to requirements of one's work, position that executor 14 can be by adjusting pull bar and tooth bar or pull bar with bend excellent single stroke or the continuous operation realized.
