Description

Technical Field

[0001] The utility model relates to a punching device, specifically, a die used for punching four walls of the end of a square tube serving as a photovoltaic component support. Background Art

[0002] It is well known in the photovoltaic bracket production industry that photovoltaic brackets are mostly square tubes. In order to facilitate on-site installation, it is necessary to process through holes for connection on the four tube walls at its end. At present, the through hole processing method on the four walls of the end of the photovoltaic bracket is to use a single punch die to punch the four walls of the end of the photovoltaic bracket four times. In this way, after the through hole on one wall is punched, the processed bracket needs to be pulled out of the mold, rotated 90 degrees and then loaded into the mold before punching the other side. In this way, to complete the punching of the four walls at the end of a bracket, it is necessary to pull the bracket out of the mold three times, rotate three times, load the bracket into the mold three times, and punch four times. Since it is necessary to pull out three times, rotate three times, load three times, and punch four times to complete the through hole processing on the four walls of the same end of a bracket, there are many operation steps and low production efficiency. Utility Model Content

[0003] The problem to be solved by the utility model is to overcome the above-mentioned shortcomings and provide a die for punching holes around the end of a photovoltaic bracket. The use of this die can reduce the operation steps and improve production efficiency.

[0004] The above-mentioned problems to be solved by the utility model are achieved by the following technical solutions:

[0005] The utility model discloses a punching die for the ends of a photovoltaic bracket, comprising a bottom plate and a top plate, wherein the bottom plate is rectangular and characterized in that: a core is provided on the bottom plate. The cross section of the core is rectangular, and its longitudinal direction is parallel to the short side of the bottom plate. There is a step on the bottom plate corresponding to the middle of the core, and there is a groove on the lower surface of the core before the step, and there is a first through groove on the bottom plate corresponding to the groove. One end of the photovoltaic bracket is sleeved on the front section of the core and abuts against the step. Baffles are connected to the bottom plates on both sides of the core, and the baffles are arranged vertically, and an upper inclined wedge, a slider, a lower inclined wedge and a guide plate are arranged between the baffles and the vertical wall of the photovoltaic bracket in sequence. Punches are provided on the two side walls of the core adjacent to the step, and the punches are connected to the grooves. There are axial holes on the guide plates corresponding to the punches, and punches are provided in the axial holes, and the outer ends of the punches abut against the corresponding sliders. There are rod holes on the baffles, and there are pull rods in the rod holes, and the two are in a movable fit. The inner end of the pull rod is connected to the corresponding slider, and a nut is provided at the outer end. There is a spring on the pull rod between the nut and the corresponding baffle. The upper part of the lower inclined wedge is a flat plate, the upper side of which is connected to the top plate, and the side adjacent to the slider has a protrusion, the cross section of which is a trapezoid, and the bottom plate corresponding to the protrusion has a first through groove. The thickness of the slider is smaller than the thickness between the lower inclined wedge and the baffle, and the upper and lower sides of the slider are both inclined, and the lower side is adapted to the upper inclined surface of the protrusion. The upper inclined wedge is block-shaped, the upper side of which is connected to the top plate, and the inner edge of the lower side is an inclined surface and adapted to the inclined surface of the upper side of the slider. There is a pressing plate in the middle of the lower surface of the top plate, which is connected to the punch press.

[0006] A further improvement of the utility model is that a first guide mechanism is provided between the front ends of the two baffles. The first guide mechanism comprises two shaft seats, which are respectively fixed on the long sides of the bottom plate on both sides of the photovoltaic bracket, and a rotating shaft is provided between them. Both ends of the rotating shaft are rotatably connected to the corresponding shaft seats, and two guide wheels are connected thereto, and the two guide wheels are arranged symmetrically and leave a spacing adapted to the photovoltaic bracket.

[0007] A further improvement of the utility model is that a second guide mechanism is provided between the first guide mechanism and the two baffles. The second guide mechanism comprises two roller frames, which are respectively connected to the bottom plates on both sides of the photovoltaic support. The roller frames are provided with guide rollers, and the roller surfaces of the guide rollers are in rolling cooperation with the outer wall of the photovoltaic support during operation.

[0008] A further improvement of the utility model is that a blanking plate is provided in the groove, and the blanking plate is arranged in an inclined shape along the length direction of the groove.

[0009] A further improvement of the utility model is that a die handle for connecting to a punch press is provided at the center of the upper surface of the top plate, and pressure blocks are provided on a pair of opposite sides thereof.

[0010] The pressing blocks are in an inverted L shape, the outer ends of their horizontal parts are arranged opposite to each other, and the outer ends of their vertical parts are connected to the top plate.

[0011] A further improvement of the utility model is that a cover plate is provided on the core behind the step, and two sides of the cover plate adjacent to two sides of the core are connected to the bottom plate through connecting plates.

[0012] A further improved solution of the utility model is that a pad is connected to the bottom of the bottom plate, and a second through groove is formed on the pad corresponding to the first through groove.

[0013] It can be seen from the above scheme that when working, the front end of the photovoltaic bracket is first placed on the rotating shaft between the two guide wheels of the first guide mechanism. After that, the photovoltaic bracket is pushed to move forward, and under the action of the two guide rollers of the second guide mechanism, the photovoltaic bracket continues to move forward until the end of the photovoltaic bracket to be punched is against the step on the bottom plate. After that, the punch press is started and the pressure plate is driven downward through the top plate until the pressure plate presses the upper wall of the bracket with the punching end. At the same time, the upper and lower inclined wedges also move down with the top plate. As the top plate moves downward, the slider is also driven to move inward a certain distance, and the punch is pushed inward until coaxial through holes are punched out on both side walls of the end of the photovoltaic bracket to be punched. After that, the punch press is released and the top plate and the pressure plate are driven to rise, so that the pressure plate leaves the photovoltaic bracket. After that, the photovoltaic bracket is taken out from the core and rotated 90 degrees, and the above actions are repeated to punch out coaxial through holes on the other two side walls of the end of the photovoltaic bracket to be punched. It can be seen that, by adopting the utility model, to complete the four wall punching of the end of a bracket, it is only necessary to pull the bracket out of the mold once, rotate it once, put the bracket into the mold twice, and punch it twice. Compared with the background technology which requires three times of pulling out, three times of rotating, three times of putting in, and four times of punching, the operation steps are reduced and the production efficiency is improved.
