Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a floating feeding mechanism outside a mold. Background Art

[0002] Existing hardware strips are often bent and cut by hardware molds. After the hardware is bent, if the bending feet affect the material strip from continuing to feed forward, it is necessary to first lift the material strip up to make the bending feet free from the interference of the mold, and then feed forward, and then enter the next cycle of bending and cutting. The shortcomings of the existing technology: 1. The lifting of the material strip and the opening and closing of the mold are not driven by the same power, so they are often not synchronized. The material strip tilts in the process, which can easily break the positioning pins; 2. The feeding mechanism is large and heavy, and occupies a lot of installation space. Summary of the invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present invention.

[0023] As Figures 1 to 3 shown, an external floating feeding mechanism for a mold includes: a support plate 1, a floating spring 2, a floating plate 3, a floating linear guide 4, a floating limit 5, a strip floating feeding track 6, a strip anti - detachment positioning mechanism 7, a strip feeding positioning mechanism 8, a strip feeding cylinder 9, a floating pressure rod 10, and a machine table 11; a support plate 1 is provided on the front side of the upper end of the machine table 11; a floating linear guide 4 is provided on the rear side of the support plate 1, and the use of the floating linear guide 4 ensures the overall stability of the structure without shaking; a floating plate 3 is provided at the rear end of the floating linear guide 4, and the bottom end of the floating plate 3 is fixed on the machine table 11; a floating spring 2 is provided at the bottom of the rear side of the floating plate 3; grooves are formed on the support plate 1 and the floating plate 3, and a floating limit 5 is provided in the grooves, and the floating limit 5 is fixed on the support plate 1 and the floating plate 3; by setting the floating limit 5, it is convenient to control the magnitude of the floating amount and ensure that the floating amount is consistent each time.

[0024] A strip floating feeding track 6 is provided at the upper end of the floating plate 3, and both the strip anti - detachment positioning mechanism 7 and the strip feeding positioning mechanism 8 are provided on the strip floating feeding track 6; a strip feeding cylinder 9 is provided on the side of the strip floating feeding track 6, and the strip feeding cylinder 9 is used in cooperation with the strip floating feeding track 6; a floating pressure rod 10 is provided at the upper end of the strip floating feeding track 6, and the floating pressure rod 10 is used in cooperation with the strip floating feeding track 6.

[0025] Furthermore, the device further includes a strip material shortage inductor 12; the strip material shortage inductor 12 is provided outside the strip floating feeding track 6 and is used in cooperation with the strip floating feeding track 6.

[0026] Furthermore, the floating pressure rod 10 is fixed to the mold template by bolts.

[0027] Furthermore, both the support plate 1 and the floating plate 3 are fixed to the machine table 11 by bolts.

[0028] Furthermore, the floating plate 3 is fixed to the strip floating feeding track 6 by bolts.

[0029] Furthermore, the height of the support plate 1 is less than the height of the floating plate 3.

[0030] Furthermore, the machine table 11, the support plate 1, and the floating plate 3 are all made of metal materials.

[0031] The usage method of this device:

[0032] Tape loading: The tape passes through the tape floating feeding track 6 and is positioned by the tape anti - detachment positioning mechanism 7. The tape material shortage inductor 12 constantly detects whether there is a shortage of tape. When there is a shortage of tape, an alarm signal is sent out.

[0033] Tape feeding: Both the tape anti - detachment positioning mechanism 7 and the tape feeding positioning mechanism 8 play a role in positioning the tape. This positioning is carried out alternately, and the power source is the tape feeding cylinder 9. The positioning is achieved by inserting the positioning pin into the tape hole. During feeding, the tape anti - detachment positioning mechanism 7 disengages from the tape, and the tape feeding positioning mechanism 8 positions the tape. The tape feeding cylinder 9 drives the tape and the tape feeding positioning mechanism 8 forward by a feeding step. Then the tape anti - detachment positioning mechanism 7 positions the tape, the tape feeding positioning mechanism 8 disengages from the tape, and the tape feeding cylinder 9 drives the tape feeding positioning mechanism 8 backward by a feeding step and returns to the feeding origin, completing a feeding cycle.

[0034] Tape floating:

[0035] When the mold is opened, the template of the mold rises, and the floating pressure rod 10 rises with the template of the mold. The floating plate 3 and the components installed thereon rise under the elastic force of the floating spring 2, finally achieving the purpose of tape floating.

[0036] When the mold is closed, the template of the mold descends with the upper mold of the mold. The power source is the power of the mold, which is an oil pressure intensifying cylinder. The floating pressure rod 10 descends with the template of the mold. There is a spring installed on the floating pressure rod 10, which provides elastic pressing power. This spring force is greater than the elastic force of the floating spring 2. The floating plate 3 and the components installed thereon descend under the elastic pressing force of the floating pressure rod 10, finally achieving the purpose of the tape descending to the cutting position.

[0037] Obviously, the above - mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to enumerate all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
