Description

Technical Field

[0001] The utility model relates to the technical field of bending equipment, in particular to a bending equipment for hardware parts. Background Art

[0002] In the field of hardware part processing, in order to meet various application requirements, hardware parts usually need to go through a bending process to form a specific shape. With the development of automation technology, realizing automatic loading and unloading of hardware parts has become the key to improving production efficiency and reducing labor costs. However, in existing hardware part processing equipment, the loading mechanism and the unloading mechanism usually adopt an independent and separated design, and this design has several significant problems.

[0003] First of all, the independent and separated design makes it difficult to ensure the coherence of the loading and unloading actions. During the loading and unloading process, it is necessary to coordinate and ensure the actions of the two mechanisms to ensure the smooth loading and unloading of the hardware parts. Once the actions are not continuous, problems such as material jamming and dislocation often occur during the transfer process, affecting production efficiency.

[0004] Secondly, the independent and separated design results in too high a cost for the equipment. Each loading and unloading mechanism requires an independent drive system and control system, which not only increases the complexity and maintenance difficulty of the equipment, but also raises the manufacturing cost of the equipment. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned drawbacks existing in the prior art, and to provide a bending equipment for hardware parts.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A forming seat is fixedly installed in front of the lower die base, and the forming seat is opposite to the bending head up and down;

[0009] Among them, a feeding channel and a discharging channel communicating with the feeding channel are arranged on the side of the lower die base. The discharging channel is opposite to the forming seat front and back. A pushing mechanism for pushing a plate member along the discharging channel into the forming seat is further installed at the rear side of the lower die base. A blanking component is further arranged on the pushing mechanism, and the blanking component is used for ejecting the bent plate member on the forming seat.

[0010] Furthermore, a guiding block is rotatably connected to the front side of the lower die base, and tension springs are connected between the guiding block and the lower die base, and between the bending head and the upper die base respectively.

The shaft end of the cylinder is fixedly installed with a mounting plate, and two push plates extending into the discharge channel are fixed on the mounting plate.

[0012] Further, the blanking assembly includes a blanking rod fixed on the mounting plate. The blanking rod penetrates through the lower die base and ejects the plate on the forming seat. The length of the blanking rod is greater than the length of the push plate.

[0013] Further, the lower die base includes a base, a mounting seat fixed on the base, and a cover plate connected to the mounting seat. The feeding channel and the discharge channel are both formed below the cover plate.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Referring to Figures 1-5 An embodiment of the present invention discloses a hardware part bending device, which includes an upper die holder 1 and a lower die holder 2. Specifically, at least one bent head 11 is rotatably connected below the upper die holder 1;

[0025] A forming seat 21 is fixedly installed in front of the lower die holder 2, and the forming seat 21 is vertically opposite to the bent head 11;

[0026] Among them, a feeding channel 22 and a discharging channel 23 communicating with the feeding channel 22 are arranged on the side of the lower die holder 2. In this embodiment, the feeding channel 22 and the discharging channel 23 are distributed in an L-shaped structure. Obviously, the feeding channel 22 and the discharging channel 23 should be distributed on two adjacent vertical planes of the lower die holder 2. The discharging channel 23 is vertically opposite to the forming seat 21. A pushing mechanism 3 for pushing a plate member to enter the forming seat 21 along the discharging channel 23 is further installed at the rear side of the lower die holder 2.

[0027] In some embodiments, a guide block 24 is further rotatably connected to the front side of the lower die holder 2 in the present invention. A tension spring (not shown in the figure) is connected between the guide block 24 and the lower die holder 2, and between the bent head 11 and the upper die holder 1. Both ends of the tension spring can be fixed by bolts. Its design purpose is to realize the reset of the guide block 24 and the bent head 11 after movement. It should be specifically noted that in this embodiment, the hardware part is bent in a two-end bending manner. Therefore, two bent heads 11 should be provided above. Of course, two guide blocks 24 should also be provided correspondingly to respectively guide and drive the two bent heads 11 to rotate before the initial bending of the hardware part to complete the bending operation of the hardware part.

[0028] Further, in this embodiment, the pushing mechanism 3 includes a bracket 31 fixed to the rear side of the lower die base 2. A cylinder 32 is fixed on the bracket 31. Wherein, a mounting plate 33 is fixedly installed at the shaft end of the cylinder 32. Two push plates 34 extending into the discharge channel 23 are fixed on the mounting plate 33. That is, during operation, the sheet to be bent enters along the feeding channel 22. At this time, the cylinder 32 pushes the mounting plate 33 to move, so as to cooperate with the push plates 34 to push the sheet in the feeding channel 22 along the discharge channel 23 onto the forming seat 21. Thereafter, the upper die base 1 is controlled to move downward by the driving unit of the stamping machine to complete the bending operation on the metal sheet on the forming seat 21.

[0029] On the basis of the above embodiment, a blanking assembly is further provided on the pushing mechanism 3 in this embodiment. The blanking assembly is used to eject the bent sheet on the forming seat 21. The design purpose of adopting the pushing mechanism 3 is to push out the formed metal parts, so as to facilitate the entry of subsequent sheets and realize continuous bending operations.

[0030] Preferably, in this embodiment, the blanking assembly includes a blanking rod 35 fixed on the mounting plate 33. The blanking rod 35 penetrates through the lower die base 2 and ejects the sheet on the forming seat 21. Wherein the length of the blanking rod 35 is greater than the length of the push plate 34. That is to say, since the length of the blanking rod 35 is greater than that of the push plate 34, before the push plate 34 pushes the subsequent sheet onto the forming seat 21, the blanking rod 35 acts first to eject the bent metal part on the forming seat 21. In this way, the connection feeding and blanking operations of the sheet can be realized, greatly improving the processing efficiency of the sheet.

[0031] In some embodiments, the lower die base 2 in the present utility model includes a base 25, a mounting seat 26 fixed on the base 25, and a cover plate 27 connected to the mounting seat 26. The feeding channel 22 and the discharge channel 23 are both formed below the cover plate 27.

[0032] On the basis of the above embodiment, in order to position the sheet when it enters, a positioning block 28 is further fixed above the mounting seat 26 in this embodiment. The positioning block 28 is used to stop the sheet to realize pre-ejection positioning. In addition, in order to realize induction before positioning, a sensor 29 is fixedly installed on the positioning block 28 in this embodiment. The sensor 29 can be set as a photoelectric sensor or a proximity switch, and can be specifically selected adaptively by those skilled in the art. Of course, the sensor 29 should be externally connected to a control unit to realize the state display when the sheet arrives.

[0033] In addition, in the present utility model, an alignment structure 4 is provided between the upper die base 1 and the lower die base 2. As a preferred embodiment, the alignment structure 4 includes guide rods fixed to the bottom of the upper die base 1, and positioning holes are provided at the upper end of the lower die base 2. The guide rods are inserted into the positioning holes to ensure accurate up-and-down die closing and die opening actions of the two. In the middle of the upper die base 1, a pressing block 13 is also movably inserted through a spring 2. The movably inserted pressing block 13 is used to press the plate on the forming seat 21 to optimize the stability of the plate position during the bending operation.

[0034] In summary, in the present utility model, the feeding channel 22 and the discharging channel 23 are used to guide the transfer of the metal sheet. With the design of the pushing mechanism 3, automatic feeding of the metal part before bending and forming can be achieved. In addition, the push plate 34 integrated on the pushing mechanism 3 can also push out the metal part formed on the forming seat 21 before feeding. In this way, a continuous feeding and discharging operation can be completed by one pushing mechanism 3. The structure design is simple and the manufacturing cost is low, which can greatly improve the stability of the metal part bending operation.

[0035] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
