Abstract

The utility model relates to a machining device for the stirrup in the building construction which is characterized in connecting a transmission device moving back and forth on a gear box. The transmission device drives a transmission shaft whose upper part is fixed with a movable arm plate that is fixed with a movable arm; moreover, a curved core is arranged above a rotating plate and is fixed on the machine frame of the stirrup curving machine. Compared with the prior device, the stirrup curving machine provided by the utility model has high working efficiency and reduces labor intensity, being able to process two angles synchronously by further improvement.

Description

Bending machine for hooping

Technical field

The utility model relates to the process equipment of stirrup in the construction.

Background technology

Existing bending machine for hooping is made up of motor, reduction box, turning cylinder, swing arm dish, swing arm, curved core and limit switch.Motor drives turning cylinder by reduction box and rotates.One end of turning cylinder is fixed with the swing arm dish, is fixed with swing arm on the swing arm dish.Also be provided with curved core above the swing arm dish, curved core is fixed on the frame; The core of will bending that also has directly is fixed on the swing arm dish.When processed reinforcing bar places between curved core and the swing arm, the operator starts power switch, motor drives the swing arm dish by reduction box and turning cylinder and rotates, when going to certain angle, under the assistance of curved core, swing arm makes bar bending, and when extremely required angle, run into limit switch, at this moment, motor quits work.The operator is with the swing arm manual reset and take out processed reinforcing bar.

From above-mentioned prior art, there is following shortcoming:

1, the operator must manually reset the swing arm dish, and to carry out next operation, inefficiency rises construction cost;

2, operator's labour intensity is bigger;

3, a kind of bending machine for hooping can only be processed a kind of angle.

Technical scheme

The purpose of this utility model provides the bending machine for hooping of the continuous operation of a kind of energy, high efficiency.Further provide and to process the bending machine for hooping of two kinds of angles simultaneously.

The technical solution of the utility model is: be connected with the transmission device that moves reciprocatingly on reduction box, this actuator drives turning cylinder rotates; The upper fixed of this turning cylinder has a swing arm dish, is fixed with a swing arm on the swing arm dish; Above rolling disc, also has a curved core.

Owing to adopted the transmission device that moves reciprocatingly, realized the automated procedure of processing.

Improvement project on the basis of the above is: above-mentioned transmission device, turning cylinder, swing arm dish and swing arm are two covers.

Because the transmission device that has adopted two covers to move reciprocatingly in the utility model is so two swing arm dishes can both automatically reset.And, the stroke difference of transmission device, thus two angle differences that the swing arm dish rotates, thereby can process different angles, to satisfy the requirement of construction.

According to the requirement in the present construction, two kinds of processed angles of stirrup are 90 ° and 60 °, therefore when two swing arms be in rotary position the time, processed reinforcing bar between the two is bent to 60 ° and 90 ° respectively.

On the basis of technique scheme, preferred scheme is a transmission device when moving reciprocatingly, and the angle that two swing arms rotate is respectively 220 ° and 180 °.Like this when each swing arm dish is in the starting position, swing arm does not contact with processed reinforcing bar, promptly not crooked it, but after turning over 90 °, just begin processing.Put at this section reinforcing bar that the handled easily person will finish a procedure in the time.

But above-mentioned angle is a rough angle, in the middle of the reality certain variation can be arranged, and also is unlikely to influence the actual use of stirrup.These data can be used as the foundation of decision transmission device stroke and the position of swing arm on the swing arm dish.Conversely, by adjusting the stroke or the position of swing arm on the swing arm dish of transmission device, can control the angle that the swing arm dish rotates.

In sum, the more existing equipment high efficiency of the bending machine for hooping that the utility model provides has reduced labour intensity, can process two kinds of angles simultaneously.

Embodiment

The utility model embodiment mainly comprises motor 1, reduction box 3, rotating shaft 9, swing arm dish 13, curved core 14 and the transmission device of being made up of crank 4, connecting rod 6, sliding rack 8 as shown in Figure 1.

In conjunction with Fig. 2 and Fig. 3, motor 1 is connected with reduction box 3 by closed coupling 2; Be connected with a crank 4 respectively in the both sides of reduction box 3, be connected with connecting rod 6 by connecting pin 5 on each crank 4, the other end of connecting rod 6 is connected with sliding rack 8 respectively by connecting pin 7 activities; Sliding rack 8 is enclosed within the guide rail 11, and with rotating shaft 9 on gear 10 interlocks; Rotating shaft 9 is movable by last shaft seat 19 and lower rotary shaft seat 18 location; Last shaft seat 19, lower rotary shaft seat 18 and guide rail 11 are fixed on the frame 12.Upper fixed in rotating shaft 9 has swing arm dish 13, is fixed with swing arm 17 on the swing arm dish 13.

In conjunction with Fig. 4, on frame 12, also be fixed with and only expect piece 16 by fastening bolt 15, only expect to have on the piece 16 the curved core 14 of strip, the front end of curved core 14 is in the top in swing arm dish 13 centers of circle.

As shown in Figure 4, the swing arm dish is in initial state, and the operator is placed on processed reinforcing bar between swing arm and the curved core; As shown in Figure 5, the swing arm dish is in rotary position, and processed reinforcing bar is 60 °.

As shown in Figure 6, be the stirrup of processed moulding.

In actual use, can also by adjust rotating shaft 9 cog 10 with the occlusal position of sliding rack 8, the rotational angle of control swing arm dish 13, and can be so that two swing arm dishes 13 are in different duties.
