Description

Technical Field

[0001] This utility model relates to the field of advertising and lightbox manufacturing technology, specifically to a simple punching machine. Background Technology

[0002] In the advertising and lightbox industry, flip-top advertising frames are a common advertising display tool. Users can easily and quickly change the advertising content through a simple flip-top operation. During the production process, holes need to be drilled between opposite ends of the bottom frame to form mounting holes. Bolts and angle brackets can then be installed in these holes to secure the advertising frame to the billboard pillar.

[0003] In existing technologies, the bottom frame of an advertising frame is drilled directly using a bench drill or electric drill. Since the bottom frame cannot be clamped and precisely positioned during the drilling process, it is easy to drill in the wrong position, which may lead to the inability to install the corner brackets properly later. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of this utility model is to provide a simple drilling machine to solve the problem that the drilling of the bottom frame of the existing advertising frame is prone to incorrect position due to the inability to clamp and accurately position, which leads to the inability to install corner brackets properly later.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a simple puncture machine, comprising:

[0007] frame;

[0008] The stamping die core is fixedly installed on the top of the frame. The stamping die core has a through stamping hole at the top and bottom. The stamping die core is used to support the bottom frame of the positioning advertising frame on the side of the hole to be drilled.

[0009] A guide support plate is fixedly installed on the top of the frame. The guide support plate is positioned above the stamping die core and has a guide hole that runs vertically through the plate. The guide hole is positioned directly above the stamping hole.

[0010] The punch is vertically slidably installed inside the guide hole;

[0011] Punch fixing plate, which is fixedly installed on the top of the punch;

[0012] The lever device, installed at the top of the frame, is hinged to the punch fixing plate and is used to drive the punch to press down and enter the guide hole and punching hole in sequence.

[0013] Furthermore, the punch fixing plate is fixedly installed with multiple vertically downward extending sliding holes, and the top surface of the guide support plate is provided with multiple upward extending guide posts, the bottom ends of the multiple guide posts being slidably installed in the multiple sliding holes.

[0014] Furthermore, the simple punching machine also includes a top plate, which is fixedly installed on the top of the punch fixing plate. The lever device is hinged to the top plate. Multiple bolts are installed between the top plate and the guide support plate. The top plate and the punch fixing plate are slidably connected to the bolts in the vertical direction. The bottom end of the bolt is fixed to the guide support plate. A compression spring is fitted on the outer circumference of the part of the bolt located between the punch fixing plate and the guide support plate.

[0015] Furthermore, a bushing is fixedly installed on the inner wall of the guide hole.

[0016] Furthermore, the stamping die core includes a die core body and a die core mounting base. The die core mounting base is fixedly installed on the top of the frame. The die core body extends horizontally outward from one side of the die core mounting base. A stepped positioning part is formed at the joint between the die core body and the die core mounting base.

[0017] Furthermore, the lever device includes a lever support base and a lever. The bottom end of the lever support base is fixedly installed on the top of the frame. One end of the lever is rotatably connected to the top of the lever support base, which can be flipped up and down. The bottom of the lever is hinged to the top of the punch.

[0018] Furthermore, the bottom ends of both ends of the guide support plate are fixedly installed on the top of the frame by the installed shims.

[0019] The beneficial effects of this utility model are as follows:

[0020] By using the aforementioned simple punching machine, the punching die core is fixedly installed at the top of the frame. Thus, the inner cavity of one end of the bottom frame of the advertising frame, where a hole is to be drilled, can be directly fitted and positioned onto the punching die core, forming a clamping effect on the bottom frame. Simultaneously, the guide hole in the guide support plate is fixedly positioned directly above the punching hole on the punching die core, and the punch is slidably installed within the guide hole. When the lever device drives the punch to press down and punch, the punch always slides vertically along the guide hole and presses down onto the bottom frame to be processed on the outer surface of the punching die core, entering the punching hole on the punching die core. Since the guide hole and the punching hole remain fixed, the positional path of the punch during downward pressing is fixed. This ensures that the punching position on the bottom frame is fixed, thereby guaranteeing the processing accuracy of the drilling position on the bottom frame and solving the problem of normal installation of the corner bracket on the bottom frame.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0043] See appendix Figure 1 To be continued Figure 5 As shown, this embodiment provides a simple punching machine 10, including a frame 100, a punching die core 130, a guide support plate 300, a punch 800, a punch fixing plate 600, and a lever device 200.

[0044] The stamping die core 130 is fixedly installed on the top of the frame 100. The stamping die core 130 is used to support and position the side of the bottom frame 20 of the advertising frame to be drilled. The inner cavity of the side of the bottom frame 20 to be drilled is fitted onto the outer surface of the stamping die core 130. The outer dimensions of the stamping die core 130 match the inner wall of the inner cavity of the side of the bottom frame 20 to be drilled. In this way, the bottom frame 20 can be stably placed on the stamping die core 130. During the placement of the bottom frame 20 on the stamping die core 130, the stamping die core 130 can also position the placement position of the bottom frame 20 to ensure that the placement position of the bottom frame 20 is consistent each time.

[0045] See attached document Figure 5 and attached Figure 8 As shown, the stamping die core 130 has a through-hole 133. When the punch 800 presses down to punch the bottom frame 20, the punch 800 will pass through the bottom frame 20 and enter the punch hole 133, thereby forming a punch on the bottom frame 20.

[0046] The guide support plate 300 is fixedly installed on the top of the frame 100 and is arranged above the stamping die core 130. The guide support plate 300 has a guide hole that runs vertically through the machine and is arranged directly above the stamping hole 133, that is, the axial direction of the guide hole and the stamping hole 133 is the same axis.

[0047] In this embodiment, the lever device 200 serves as the power source for the punch 800 when it is pressed down. The operator presses down the lever device 200, causing the punch 800 to move downwards and punch a hole in the bottom frame 20. Using the lever device 200 as the power source for the punch 800 allows for better adaptation to outdoor operations, enabling manual punching and adapting to outdoor working environments without electricity. Furthermore, the lever device 200 is a labor-saving mechanism, reducing the operator's workload.

[0048] The bottom of the lever device 200 is fixedly connected to the punch fixing plate 600, and the top of the punch 800 is fixed on the punch fixing plate 600. In this way, when the lever device 200 is pressed down, it can simultaneously drive the punch 800 to move downward and press down.

[0049] See attached document Figure 4 Appendix Figure 6 Appendix Figure 7 and appendix Figure 9 As shown, the punch 800 is vertically slidably installed in the guide hole of the guide support plate 300. That is, during the up and down movement of the punch 800 following the lever device 200, the punch 800 is always in the guide hole. Since the guide hole and the punching hole 133 are always in a fixed state, the position path of the punch 800 when it is pressed down is fixed. This ensures that the punching position of the punch 800 on the bottom frame 20 is fixed, thereby ensuring the processing accuracy of the drilling position on the bottom frame 20 and solving the problem of normal installation of the corner bracket on the bottom frame 20.

[0050] See attached document Figure 5 and attached Figure 8 As shown, in some embodiments, the stamping die core 130 includes a die core body 132 and a die core mounting base 131. The die core mounting base 131 is fixedly mounted on the top of the frame 100. The die core body 132 extends horizontally outward from one side of the die core mounting base 131, and a stepped positioning portion 900 is formed at the junction of the die core body 132 and the die core mounting base 131. The stepped positioning portion 900 can be used to position the mounting position of the bottom frame 20. Specifically, the cross-sectional dimension of the mold core body 132 can be designed to be smaller than the cross-sectional dimension of the mold core mounting base 131. In this way, during the process of fitting the inner cavity of the bottom frame 20 onto the mold core body 132, when the front end of the bottom frame 20 moves to the step positioning part 900, the front end of the bottom frame 20 will come into contact with the mold core mounting base 131. Since the cross-sectional dimension of the mold core mounting base 131 is larger than the cross-sectional dimension of the mold core body 132, a step will be formed at the joint between the mold core mounting base 131 and the mold core body 132. The mold core mounting base 131 will prevent the front end of the bottom frame 20 from moving forward, thus forming a positioning function. At this time, it means that the bottom frame 20 has been installed in place on the mold core body 132.

[0051] Continue to refer to the appendix Figure 5 and attached Figure 8As shown, the punch fixing plate 600 has multiple vertically downward extending sliding holes fixedly installed on it, and the top surface of the guide support plate 300 has multiple upward extending guide posts 140. The bottom ends of the multiple guide posts 140 are slidably installed in the multiple sliding holes. By installing guide posts 140 between the punch fixing plate 600 and the guide support plate 300, the punch fixing plate 600 can slide up and down along the guide posts 140 when it slides up and down. The guide posts 140 are fixedly installed on the guide support plate 300 below, which ensures the accuracy of the position of the punch fixing plate 600 when it moves up and down, and thus ensures the accuracy of the position of the punch 800 during its up and down movement.

[0052] See attached document Figure 7 As shown, in some embodiments, a bushing 400 is installed on the inner wall of the guide hole to improve the wear resistance of the guide hole and avoid the need to frequently replace the guide support plate 300 due to wear caused by direct contact between the punch 800 and the guide hole.

[0053] See attached document Figure 1 Appendix Figure 4 and appendix Figure 7 As shown, the simple punching machine 10 also includes a top plate 700, which is fixedly installed on the top of the punch fixing plate 600. The lever device 200 is hinged to the top plate 700. Multiple bolts 110 are installed between the top plate 700 and the guide support plate 300. The top plate 700 and the punch fixing plate 600 are respectively slidably connected to the bolts 110 in the vertical direction. The bottom end of the bolt 110 is fixed to the guide support plate 300. A compression spring 120 is fitted on the outer circumferential surface of the part of the bolt 110 located between the punch fixing plate 600 and the guide support plate 300.

[0054] As the lever device 200 moves the top plate 700 and the punch fixing plate 600 downward, the punch fixing plate 600 compresses the compression spring 120 downward, causing the punch fixing plate 600 to gradually move closer to the guide support plate 300. After the punch 800 completes the punching operation on the bottom frame 20, the operator removes the downward pressure applied to the lever device 200. Since the compression spring 120 is in a compressed state at this time, the compression spring 120 extends and resets, causing the punch 800 and the punch fixing plate 600 to move upward automatically, thus realizing the automatic reset of the punch fixing plate 600 and the top plate 700.

[0055] See attached document Figure 1As shown, in this embodiment, the lever device 200 includes a lever support 201 and a lever 202. The bottom end of the lever support 201 is fixedly mounted on the top end of the frame 100. One end of the lever 202 is rotatably connected to the top end of the lever support 201, and the bottom end of the lever 202 is hinged to the top end of the punch. When punching is required on the bottom frame 20, the operator presses the lever 202 downward, causing the lever 202 to flip downward relative to the lever support 201, thereby driving the punch 800 to punch holes in the bottom frame 20 below.

[0056] See attached document Figure 2 As shown, in some embodiments, the bottom ends of both ends of the guide support plate 300 are fixedly mounted to the top of the frame 100 by mounting shims 500. The shims 500 increase the distance between the guide support plate 300 and the top of the frame 100, which facilitates the placement of the bottom frame 20 on the frame 100. Furthermore, by installing shims 500 only at the bottom of the opposite ends of the guide support plate 300, the installation height of the guide support plate 300 can be increased without making the overall thickness of the guide support plate 300 too thick, thus saving material. It is also understood that the bottom of the opposite ends of the guide support plate 300 can be made thicker, while the middle part has a slotted structure.

[0057] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
