DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a frame forming mechanism, comprising:

[0025] The inner mold 100 is controlled to move by a linear mechanism 101;

[0026] Two clamping blocks 200 are arranged at a relative interval, the clamping blocks 200 are arranged on the sliding part 201, and a cushion block 202 is arranged between the clamping blocks 200 and the sliding part 201;

[0027] The wedge block 300 and the two connecting rods 301 are connected to the sliding part 201 . The movement of the wedge block 300 drives the two connecting rods 301 to move closer to / away from each other, thereby driving the two clamping blocks 200 to hold / move away from the inner mold 100 .

[0028] In this embodiment, the inner mold 100 moves downward to press the b side of the frame K, the wedge block 300 moves to drive the two connecting rods 301 to approach, and drives the two clamping blocks 200 to hold the inner mold 100, so that the frame K enters the two clamping blocks 200, and the a side and c side of the frame K are turned over to approach the two sides of the inner mold 100, and the d side of the frame K is blocked due to sinking and surrounds the top side of the inner mold 100, and the frame K is initially formed. It should be noted that at this time, the d side of the frame K is in a preliminary overlapping state;

[0029] Since the clamping block 200 is arranged on the sliding part 201, the sliding part 201 can drive the clamping block 200 to hold / move away from the inner mold 100, that is, the frame is enclosed and then formed on the inner mold, and by replacing the pads 202 with different thicknesses, a small range of adjustment of the clamping size can be achieved, thereby adapting to the clamping and forming operation of frames K of different sizes, and the overall structure is simple, which is convenient for pre-adjustment and maintenance in the later stage, reducing costs.

[0030] In one embodiment, a fixing portion 204 is disposed at the outer end of the sliding portion 201 , and the sliding portion 201 and the fixing portion 204 are connected via an elastic member 203 .

[0031] This embodiment is configured such that when the wedge block 300 moves to drive the two connecting rods 301 to move closer / away and drive the two clamping blocks 200 to clamp / move away from the inner mold 100, the elastic member 203 can provide the clamping blocks 200 with a certain buffer stroke and can assist in automatically resetting the clamping blocks 200. Most importantly, the distance range that the sliding portion 201 can move outward can be adjusted by adjusting the elastic member 203. For example, when the size of the frame becomes smaller, the distance range that the sliding portion 201 can move outward can be limited by tightening the elastic member 203 to adapt to the smaller size of the frame. When the size of the frame becomes larger, the distance range that the sliding portion 201 can move outward can be loosened by loosening the elastic member 203 to adapt to the larger size of the frame. That is, by adjusting the elastic member 203, the clamping size can be adjusted within a larger range.

[0032] Specifically, the elastic member 203 may be a spring, a telescopic cylinder or the like.

[0033] In one embodiment, the wedge block 300 is controlled to move linearly through the driving mechanism 302. In this embodiment, by controlling the wedge block 300 to actively move vertically and contact the connecting rod 301, the two clamping blocks 200 are controlled to clamp / leave the inner mold 100, thereby realizing the opening and closing operation of the clamping action of the surrounding frame K, which is simple, fast and efficient.

[0034] Specifically, the driving mechanism 302 may be a cylinder, a linear motor or the like.

[0035] In one embodiment, a support plate 500 is further included to receive the inner mold 100;

[0036] Specifically, a support member 501 is provided at the bottom thereof, and the support member 501 is provided on a bracket 502 .

[0037] This embodiment is configured such that the support plate 500 is used to receive the b side of the surrounding frame K when the surrounding frame K is pressed down by the inner mold 100 , and together with the inner mold 100 and the clamping block 200 , the surrounding frame K is formed on the outer side of the inner mold 100 .

[0038] Preferably, the support member 501 has a retractable function, and specifically can adopt a spring or a combination structure of a small cylinder and a large cylinder or other achievable structures.

[0039] In one embodiment, a reference plate 400 is further included, on which a slide rail 401 is disposed, the inner mold 100 and the support plate 500 are both disposed on the slide rail 401 through a connecting piece, the wedge block 300 is disposed on the reference plate 400, and the sliding portion 201 is slidably disposed on the reference plate 400. Specifically, in this technical solution, the support plate 500 is connected to the slide rail 401 through a bracket 502.

[0040] This arrangement of the present embodiment can unify the longitudinal reference. When processing the enclosures K of different sizes, it is only necessary to adjust the transverse dimensions of the forming mechanism to adapt, thereby reducing the difficulty of pre-adjustment and improving efficiency.

[0041] In one embodiment, the linear mechanism 101 may adopt a linear module / cylinder / linear motor.

[0042] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that satisfy both A and B. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
