As shown in fig. 3 to 8, the present embodiment provides a reinforcement cage auxiliary jig and a reinforcement cage manufacturing apparatus using the same.
Fig. 1 to fig. 2 show the structure of a reinforcement cage 10 suitable for the reinforcement cage auxiliary jig and the reinforcement cage production equipment provided in this embodiment. The reinforcement cage 10 includes angle bars 11, transverse bars 13, and longitudinal bars 12.
The angle bars 11 are provided in plurality and arranged at intervals in the front-rear direction, and each angle bar 11 includes a first reinforcing bar 111 extending in the left-right direction and a second reinforcing bar 112 connecting the right end surface of the first reinforcing bar 111 and extending upward.
The transverse ribs 13 are provided in plurality and are spaced apart along the upper layer longitudinal ribs 121.
The corner bars 11, the transverse bars 13 and the longitudinal bars 12 are bound and fixed at staggered positions to form the reinforcement cage 10.
Referring to fig. 3 and 4, the reinforcement cage auxiliary jig includes:
a first stopper structure 20 for upwardly supporting the first reinforcing bars 111 and restricting the first reinforcing bars 111 from moving in the front-rear direction;
A second stopper 30 for limiting the movement of the second reinforcing bar 112 to the right, forward and backward when the first reinforcing bar 111 is placed on the first stopper 20;
and a fixing structure 40 for driving the control rib 1201 to move towards the corner of each corner rib 11 so as to interfere with each corner rib 11.
Those skilled in the art can understand that the auxiliary jig for the reinforcement cage further comprises fixing structures respectively used for temporarily fixing the upper-layer longitudinal bar 121, the lower-layer longitudinal bar 122 and the transverse bar 13, and the fixing modes can be clamping, buckling, limiting and the like.
In this embodiment, in combination with the position relationship between the corner rib 11 and the control rib 1201, the first limiting structure 20 is disposed on the first steel bar 111 to limit the downward, forward and backward movement of the first steel bar, the second limiting structure 30 is disposed on the second steel bar 112 to limit the rightward, forward and backward movement of the second steel bar, and the control rib 1201 and the stabilizing structure are used to limit the upward movement of the first steel bar 111 and the leftward movement of the second steel bar 112. Specifically, the method comprises the following steps: the first reinforcement 111 and the second reinforcement 112 are perpendicular to the control rib 1201, and the control rib 1201 abuts against the corner of the corner rib 11 (i.e. the joint of the first reinforcement 111 and the second reinforcement 112), so that the upward movement of the first reinforcement 111 and the leftward movement of the second reinforcement 112 can be simultaneously limited. In other words, the position control of the control rib 1201 by the stabilizing structure 40 can simultaneously realize the upward limit of the first reinforcing bar 111 and the leftward limit of the second reinforcing bar 112, thereby facilitating the simplification of the structure.
Because angle muscle 11 has a plurality ofly and sets up (fore-and-aft direction) along control muscle 1201 interval, when control muscle 1201 supports the corner that holds each angle muscle 11, under stabilizing structure 40, first limit structure 20 and second limit structure 30's cooperation, each angle muscle 11 and control muscle 1201 overall structure realize stabilizing to effectively avoid overall structure to place at other reinforcing bars, fix or each reinforcing bar rock at the ligature in-process.
It should be noted that each of the corner ribs 11 abuts against the control rib 1201, in other words, the control rib 1201 is simultaneously limited by a plurality of corner ribs 11, so that the stability of each of the corner ribs 11 and the control rib 1201 can be simultaneously achieved by applying a downward oblique acting force to one acting point of the control rib 1201. That is, only one stabilizing structure 40 is needed to realize the position control of the control rib 1201 and all the corner ribs 11, thereby greatly simplifying the structure.
In the illustrated structure, there are two stabilizing structures 40, so that the control rib 1201 is subjected to two forces, which is beneficial to improve the stability of the overall structure formed by the corner ribs 11 and the control rib 1201. The number of the stabilizing structures 40 can be specifically set to one, three, five, etc. according to actual needs by those skilled in the art, and is not limited herein.
In addition, it should be considered that, in the production process of the reinforcement cage 10, the reinforcement bars are generally placed on the reinforcement cage auxiliary jig from the upper side to the lower side, and if the first limiting structure 20 is replaced by a fixing structure which simultaneously limits the first reinforcement bar 111 from the upper side to the lower side, the structure is complicated by the arrangement; for example, in the present embodiment, since the first limiting structure 20 only needs to limit the first steel bar 111 in the downward, forward, and backward directions, a simple Y-shaped supporting member can be used, and if the four directions are limited and fixed, only more complicated structures such as clamps can be selected; furthermore, the fixing structure for limiting the four directions may hinder the upward moving-out operation of the reinforcement cage 10 after the bundling is completed; finally, because the fixing structures are relatively independent and have no integral coordination relationship (the relatively independent and the integral coordination relationship means that each fixing structure can only influence a single steel bar fixed by the fixing structure but cannot influence other steel bars), in the process of binding the steel bars, if the size deviation of individual fixing structures or the matching problem between the individual fixing structures and the steel bars exists, the steel bars are loosened and shaken; the stabilizing structure 40 of the present embodiment acts on the control rib 1201, and can limit the corner ribs 11 at the same time, so as to stabilize the overall structure, and reduce the influence of the size deviation of the individual first limiting structure 20 or the second limiting structure 30 on the stability of the overall structure.
In another embodiment of the present application, the stabilizing structure 40 includes a hooking member 41 and a driver 42, the hooking member 41 is used for hooking the control rib 1201, and the controller is used for driving the hooking member 41 to move so that the control rib 1201 moves to the corner of the corner rib 11.
The hooking member 41 has a hook-shaped structure, and may be an arc or a frame shape having an opening. The hook piece 41 and the driver 42 are adopted to control the movement of the control rib 1201, and the structure is simple.
In another embodiment of the present application, referring to fig. 4 and fig. 5, the hooking element 41 includes a carrier 411 disposed horizontally, a push plate 412 connected to a left end surface of the carrier 411 and extending upward, and a guide plate 413 connected to the push plate 412 and disposed obliquely rightward, an avoiding space for the control rib 1201 to be inserted is left between the guide plate 413 and the carrier 411, and the driver 42 drives the carrier 411 to move rightward to make the control rib 1201 abut against each of the corner ribs 11.
In this embodiment, the upper surface of the carrier 411 and the upper surface of the first steel bar 111 have the same horizontal position, when the hooking element 41 hooks the control rib 1201, the control rib 1201 abuts against the first steel bar 111, and when the hooking element 41 moves to the right, the control rib 1201 abuts against the second steel bar 112 to the right. In other words, in the present embodiment, the hook 41 moves left and right. By the height design of the hooking member 41, the effect that the control rib 1201 abuts against the first reinforcing steel bar 111 is achieved. In other embodiments, the hook 41 moves in a downward and rightward direction, and a downward and rightward force is applied to the angle iron to press the control rib 1201 against the first and second reinforcing bars 111 and 112 simultaneously.
In this embodiment, the guide plate 413 is obliquely disposed, so that the control rib 1201 is guided downward by the guide plate 413 to a position abutting against the push plate 412 as the hook 41 moves rightward after passing through the escape space, and is pushed to a position abutting against the second reinforcing bar 112 by the push plate 412 as the hook 41 moves further rightward. The guide 413 is provided to guide insertion of the control rib 1201.
In another embodiment of the present application, referring to fig. 4 and 7, the second limiting structure 30 includes a front left clamping member 31, a right rear clamping member, and a control member 33 for driving the left front clamping member and the right rear clamping member to move toward or away from each other, and the front clamping member and the rear clamping member move toward each other, so that the left clamping member 31 and the right clamping member 32 can clamp the second steel bar 112. The front and rear clamp left and right clamp members 31 and 32 are disposed in front of and behind each other, and the second reinforcing bars 112 enter the front and rear clamp members from the left side and are clamped by the front and rear clamp members 112.
Preferably, referring to fig. 6, a plurality of the second limiting structures 30 are fixed on a cross beam 50, and the cross beam 50 is driven by an air cylinder 60 to move up and down. The operator can adjust the height of the second position limiting structure 30 according to the length of the second reinforcing bars 112. The height of each second limiting structure 30 is adjusted through the up-and-down movement of the cross beam 50, and the structure and the control are simplified.
Referring to fig. 4, in the embodiment, the first limiting structure 20 has two structures, the first structure includes at least one Y-shaped supporting member with an upward Y-shaped opening (see fig. 8). The second kind includes the stand and locates the stand and last fagging and lower fagging that set up from top to bottom, and lower fagging is used for supporting first reinforcing bar 111 to carry on spacingly to first reinforcing bar 111 front and back direction together with the stand, go up the fagging and have two and be used for the horizontal muscle 13 of backup pad jointly and restrict the back-and-forth movement of horizontal muscle 13.
