Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a clamping device for punching holes in hardware processing. Background Art

[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting, which are used to fix things, process things, and decorate. For example, angle brackets are a kind of hardware, which are mainly used to connect components that intersect at right angles of 90 degrees. They are an important connecting component in architecture. In the production and processing of angle brackets, punching equipment is needed to punch holes in them. In order to prevent them from shifting during the punching process, a clamping device is needed to limit and fix them when punching holes in the angle brackets. However, the current clamping device is not convenient for fixing according to angle bracket products of different lengths during use, which makes the device small in scope of application and low in work efficiency. Therefore, we propose a clamping device for hardware processing and punching to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a clamping device for hardware processing and punching proposed by an embodiment of the utility model comprises a support plate 1, a movable punching mechanism body 2 is installed on the top of the support plate 1, a mounting plate 3 is fixed at the through hole opened on the top of the support plate 1, two cross plates 4 are fixed at the bottom of the mounting plate 3, a bidirectional screw rod 5 is rotatably connected between the two cross plates 4 through a bearing, both ends of the bidirectional screw rod 5 are threadedly connected with a U-shaped plate 6 adapted to the surface thread thereof, a support rod 14 is fixed between the two cross plates 4, the two U-shaped plates 6 both slide on the surface of the support rod 14, and can play an auxiliary supporting role for the U-shaped plates 6, the U-shaped plates 6 both slide through the mounting plate 3 to extend above it and are fixed with a guide plate 7, a side wall of the U-shaped plate 6 is fixed with a connecting plate 8, two cylinders 9 are fixed on the top of the connecting plate 8, a movable frame 10 is fixed to the ejection end of the corresponding two cylinders 9, and a movable frame 10 is fixed to the bottom of the movable frame 10 The clamping plate 11 matched with the guide plate 7 and the bottom of the mounting plate 3 are provided with an adjusting plate assembly 12. When using this clamping device, the motor is started to drive the bidirectional screw rod 5 to rotate. After the bidirectional screw rod 5 rotates, it will drive the two U-shaped plates 6 to move in the opposite direction. After the U-shaped plate 6 moves, it will drive the guide plate 7 to move, so that the length of the corner code plate for punching and processing can be adjusted according to the needs. After the adjustment is completed, a certain number of corner code plates can be placed in the card slots on the two guide plates 7, and then the cylinder 9 can be started to drive the moving frame 10 to move downward. After the moving frame 10 moves downward, the corner code plate can be limited and fixed to prevent it from moving during the processing. After the processing is completed, the motor is started to drive the U-shaped plate 6 to move to the maximum distance on both sides. At this time, the processed corner code plate can be automatically unloaded, and with the cooperation of the adjusting plate assembly 12, the debris generated during the processing can be collected to facilitate the staff to clean it up later.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the adjustment plate assembly 12 includes a frame 1201 connected and fixed to the bottom of the mounting plate 3, and a buffer inclined plate 13 is fixed inside the frame 1201, which can buffer the falling of the punched hardware and reduce the collision between the hardware and the rotating plate 1203. The interior of the frame 1201 is rotatably connected to a rotating shaft 1202 through a bearing, and a rotating plate 1203 adapted to the frame 1201 is fixed on the surface of the rotating shaft 1202. Both sides of the frame 1201 are provided with a rotating plate 1203 adapted to the rotating plate 1203 is matched with the yield opening 1204. During the punching process of the corner code plate, a waste collection box and a product collection box can be placed on both sides of the bottom of the support plate 1 respectively. The motor is started to drive the rotating shaft 1202 to rotate left or right first. When the rotating shaft 1202 rotates, it will drive the rotating plate 1203 to tilt accordingly. At this time, the waste chips generated during the processing will fall into the waste collection box. After the punching is completed, only the rotating plate 1203 needs to be rotated in the opposite direction. At this time, the processed corner code plate will fall into the inside of the product collection box.

[0026] like Figure 2 As shown, in some embodiments, two strip grooves 15 adapted to the U-shaped plate 6 are opened on the top of the mounting plate 3, which play a role of giving way so that the U-shaped plate 6 will not be interfered with when moving, and can also play a role of limiting. When the bidirectional screw rod 5 rotates to drive the U-shaped plate 6 to move, it can prevent the U-shaped plate 6 from rotating synchronously with the bidirectional screw rod 5.

[0027] like Figure 5 As shown, in some embodiments, a first connecting rod 16 is equidistantly fixed to one side wall of one guide plate 7, and one side wall of the first connecting rod 16 is slidably connected to a second connecting rod 17, and one end of the second connecting rod 17 is fixedly connected to a side wall of another guide plate 7, which can provide auxiliary support for the angle code plate during processing and prevent it from deformation during the punching process.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
