Description

Electronic gantry frame type mould bases

The utility model relates to the device, particularly electric press mould bases of hardware machinery processing.

The equipment that mould bases is five metals processing, machine industry is commonly used plays guiding, matched moulds punching press to mould up and down.Traditional mould bases adopts foot-propelled or manually punching press, as Chinese patent 96237780.5 and 96237781.3 disclosed " foot-operated gantry frame type mould bases " and " manually gantry frame type mould bases ", owing to adopting manually or foot-operated being used as power, labor strength is bigger, production efficiency is not high, and is relatively poor to the punching press effect of thick and heavy material.

The purpose of this utility model is the weak point that overcomes above-mentioned prior art, and the electronic gantry frame type mould bases that a kind of processing dimension scope is big, effective, production efficiency is high is provided.

The purpose of this utility model is achieved by the following technical solution: electronic gantry frame type mould bases, including frame, upper rack places the two vertical chutes that are parallel to each other on the workbench of counterdie, the workbench, slide block that patrix is installed on chute top, is hinged to the pull bar of rocker-slider mechanism with slide block, chute and is loaded on motor and transmission device below the workbench, a main shaft is equipped with in the workbench below, the main shaft two ends are fixed with eccentric wheel, and eccentric wheel is hinged with pull bar again; The reduction gearing of transmission device is loaded on the main shaft by bearing, and the clutch transmission that cooperates with reduction gearing also is housed on the main shaft.Further, clutch transmission by the runner of band dead slot, be loaded on push rod in the runner dead slot and spring, the wedge shape clutch that cooperates with the push rod upper inclined surface is pitched and be with the foot-operated connecting rod of back-moving spring to constitute, have on the reduction gearing and the flexible semi-circular groove that is clasped of push rod, wedge shape clutch fork is close on the runner excircle, and under the drive of foot-operated connecting rod, can interact with the inclined-plane of push rod, change the position that push rod inserts the semi-circular groove of reduction gearing.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are described further.

Ginseng Fig. 1-Figure 10, the frame 1 of present embodiment is the shaped as frame structure, top is the fixing workbench 2 of counterdie, two mutual parallel chutes 3 vertically are housed on the workbench 2, slide block 4 is assemblied between two chutes 3 and forms and is slidingly matched, slide block 4 two ends are hinged pull bar 5 (as shown in Figure 2) respectively, pull bar 5 extend frame 1 bottom and eccentric wheel 6 hinged, two eccentric wheels 6 are fixed in the two ends of main shaft 8, when main shaft 7 rotates, by the rocker-slider mechanism of eccentric wheel 6, pull bar 5, slide block 4, one group of symmetry of chute 3 formation, realize the folding up and down of module 4.For control operation better, the bottom of frame 1 is fixed with motor 8, motor 8 is by belt pulley 9 and gear drive deceleration main shaft 7, wherein reduction gearing 10 is loaded on the main shaft 7 by bearing, coaxial mounted with reduction gearing 10 is a runner 11, runner 11 is close to reduction gearing 10, but with main shaft 7 be connected (as shown in Figure 4), have dead slot 12 on the runner 11, one spring 13 and " L " shape push rod 14 are housed (as Fig. 7 in the dead slot 12, shown in 8), be close on runner 11 excircles is that wedge shape clutch fork 15 is (as Fig. 9, shown in 10), the wedge shape clutch is pitched 15 tops and is cooperated with the inclined-plane 16 of push rod 14, the bottom then with foot-operated connecting rod 17 be connected (as shown in Figure 3), like this, runner 11, spring 13, push rod 14, wedge shape clutch fork 15, the semi-circular groove 18 that has on foot-operated connecting rod 17 and the reduction gearing 10 constitutes clutch transmission.

The course of work is such: initial state such as Fig. 4, Fig. 5, wedge shape clutch fork 15 acts on the inclined-plane 16 of push rod 14, extruding push rod 14 and spring 13, make push rod 14 break away from the semi-circular groove 18 of reduction gearing 10 fully, runner 11 is separate with reduction gearing 10, when motor 8 rotated, reduction gearing 10 dallied on main shaft 7, and main shaft 7, runner 11 etc. are all static.When stepping on foot-operated connecting rod 17, wedge shape clutch fork 15 moves down and separates with push rod 14, fail to keep an appointment bundle and be subjected to the elastic force effect of spring 13 to stretch the semi-circular groove 18 that injects reduction gearing 10 of push rod 14, reduction gearing 10 links (as shown in Figure 6) with runner 11 like this, thereby drive main shaft 7 rotations, main shaft 7 makes slide block 4 actions by eccentric wheel 6, pull bar 5.In case unclamp foot-operated connecting rod 17, be subjected to move on the foot-operated connecting rod 17 of effect of back-moving spring 19 and reset, wedge shape clutch fork 15 is close on the excircle of runner 11 again, and 16 effects of the inclined-plane when push rod 14 forwards to and on the push rod 14 are pushed push rod 14 and spring 13 again, make push rod 14 withdraw from the semi-circular groove 18 of reduction gearing 10 once more fully, make runner 11 and reduction gearing 10 break away from interlock, only remaining reduction gearing 10 idle running, main shaft 7 is static.

Structural advantages of the present utility model is:

1, adopts foot-operated solenoidoperated cluthes, control easily the duty of mould bases, by motor Drive, production efficiency is higher;

2, greatly reduce that labour intensity, more convenient operation are simple, crudy is more guaranteed;

3, swing-bar mechanism ensuring smooth transmission, mobile range are big, and the range of work is enlarged.
