Description

Technical Field

[0001] This utility model relates to a punching structure, and more specifically, to a punching device for metal shelves. Background Technology

[0002] In the production and processing of metal shelves, drilling holes in shelf components is involved. Shelves are typically assembled from round and rectangular tubes, requiring precise drilling into the tubes to ensure a tight connection between components and guarantee the structural stability and safety of the shelf. However, existing drilling methods have several drawbacks. First, operators must hold the drilling equipment while simultaneously stepping on the component to be drilled for stability before drilling. While this method has less impact on rectangular tubes, it significantly affects round tubes due to their tendency to slide. In practice, relying solely on foot to stabilize the round tube is ineffective, making it difficult to ensure the tube remains stable throughout the drilling process. This can lead to deviations in the drilling position and affect the assembly accuracy of the shelf. Second, operators must simultaneously hold the heavy drilling equipment and constantly monitor the tube's stability, resulting in extreme labor intensity. Prolonged operation can cause operator fatigue, further reducing accuracy and increasing the defect rate. In addition to manual fixing, a dedicated drilling workbench can be used, with the drilling equipment positioned alongside it. The operator holds the part to be drilled and moves it under the drilling equipment to drill. Compared with the first method, although the operator no longer needs to hold the drilling equipment, he still needs to manually support the round tube for positioning and operation. This not only fails to effectively reduce the operator's labor intensity, but also makes it difficult to guarantee the accuracy of positioning each time during the frequent movement of the round tube, and drilling deviation is still difficult to avoid. In addition, due to the need for frequent manual operation, the production efficiency is also low.

[0003] In summary, existing methods for drilling holes in the round tubes of metal shelving systems have shortcomings in terms of positioning accuracy, operator workload, and production efficiency. Therefore, those skilled in the art are dedicated to developing a drilling device that can effectively solve these problems. Utility Model Content

[0008] The upper part of the front half of the long strip-shaped stabilizing base is provided with a third support base, the third support base is provided with a second positioning groove, and the outer end of the third support base is provided with a limit end plate.

[0009] Furthermore, the operating box includes a base, and two side plates are arranged along the length of the base. Each side plate has a baffle detachably arranged at both ends, and windows are opened on both sides of each side plate.

[0010] The positioning cylinder is mounted on the base. Both sides of the first support and the second support are connected to the inner wall of each side plate through several side columns. The lower ends of the first support and the second support are connected to the base through several upright columns.

[0011] Furthermore, the displacement seat is slidably sleeved on the four columns located on the inner side;

[0012] Guide seats are provided on both sides of the first support and the second support, and each guide rod is slidably connected to the first support and the second support through the guide seats.

[0013] Furthermore, a third positioning groove is provided at the lower end of the upper positioning seat, and the third positioning groove, the second positioning groove, and the two first positioning grooves are all V-shaped.

[0014] Furthermore, two first weight-reducing holes are provided along the length of the elongated stabilizing base, and a second weight-reducing hole is provided on the third support base. A handle is provided on one side of the third support base.

[0015] Furthermore, both the lower ends of the first and second support seats are provided with guide channels, and both sides of the elongated stabilizing seat are provided with guide rails. The elongated stabilizing seat is slidably connected to the first and second support seats through the guide rails and guide channels.

[0016] Furthermore, an elongated through-hole is provided on the side plate, and a fixed seat is provided at the rear end of the elongated stabilizing seat. A locking screw is provided on one side of the fixed seat. The locking screw is slidably located at the elongated through-hole, and the outer half of the locking screw extends out of the operating box through the elongated through-hole and is threaded with a locking sleeve.

[0017] Furthermore, the base is provided with two pulley support seats, and each of the supporting pulleys is slidably located on the respective pulley support seat.

[0018] Furthermore, the first support base and the second support base are located in the middle section of the operating box.

[0045] Guide seats 26 are provided on both sides of the first support seat 6 and the second support seat 7, and each guide rod 5 is slidably connected to the first support seat 6 and the second support seat 7 through each guide seat 26.

[0046] The lower end of the upper positioning seat 8 is provided with a third positioning groove 27, and the third positioning groove 27, the second positioning groove 16 and the two first positioning grooves 11 are all V-shaped.

[0047] Two first weight-reducing holes 28 are provided along the length of the elongated stabilizing base 12, and a second weight-reducing hole 29 is provided on the third support base 15. A handle 30 is provided on one side of the third support base 15.

[0048] The lower ends of the first support base 6 and the second support base 7 are provided with guide channels 31, and the two sides of the elongated stabilizing base 12 are provided with guide rails 32.

The outer half of the locking screw 36 extends out of the operating box 1 through the elongated through-hole 33 and is threaded with a locking sleeve 37.

[0050] The base 18 is provided with two pulley support seats 38, and each of the supporting pulleys 13 is slidably located on each of the pulley support seats 38.

[0051] The first support base 6 and the second support base 7 are located in the middle section of the operating box 1. A storage rack 50 is provided on one side of the front half of the operating box 1. The lower end of the operating table 51 is connected to both the operating box 1 and the upper end of the storage rack 50. The operating table 51 is divided into a temporary storage area 53 and an operating area 55 by several support rods 52.

[0052] A drilling machine 56 is provided on one side of the operating box 1. A drilling bit 57 is provided on the drilling machine 56. The drilling machine 56 is used to drive the drilling bit 57 to rotate and move up and down. The drilling bit 57 is located directly above the drilling opening 10.

[0053] The optimal working principle of this utility model is as follows:

[0054] Place the round tube to be drilled (not shown in the figure) in the operation area 55. The temporary storage area 53 can hold the round tube to be processed or processed. The operator pushes the third support seat 15 of the round tube in the direction until the part of the round tube to be drilled is between the two lower positioning seats 9 and directly below the drilling opening 10. When the tube is long or multiple holes need to be drilled along the length of the round tube, one end of the tube can be placed in the second positioning groove 16 of the third support seat 15 to reduce the shaking of the tube during drilling and improve stability. At this time, there is no need to use the over-positioning long strip type stabilizing seat 12 to limit the position of the third support seat 15. The third support seat 15 plays a supporting role.

[0055] Then, the positioning cylinder 2 is activated, and its output end pulls the displacement seat 3 downward. The moving displacement seat 3 drives the guide rods 5 at the four corners to slide down along the guide seats 26 on both sides of the first support seat 6 and the second support seat 7, causing the upper positioning seat 8 to descend. The third positioning groove 27 at the lower end of the upper positioning seat 8 contacts the pipe, working in conjunction with the first positioning groove 11 and the second positioning groove 16 to stabilize the pipe from multiple directions, preventing it from moving during drilling. Drilling can then be performed by the operator using a handheld drilling device, or directly by using the drilling machine 56. Both the handheld drilling device and the drilling machine 56 are existing technologies and can be selected according to needs.

[0056] As a further preferred embodiment of this invention, before drilling, the support base 15 can be adjusted according to the drilling length. Specifically, the operator holds the handle 30 on one side of the third support base 15 and pushes the elongated stabilizing base 12. The guide rails 32 on both sides of the elongated stabilizing base 12 slide within the guide channels 31 at the lower ends of the first support base 6 and the second support base 7. The support pulley 13 at the lower end rolls on the pulley support 38 of the base 18 to achieve position adjustment. After the position is adjusted, the locking sleeve 37 on the locking screw 36 is tightened to position the elongated stabilizing base 12. Since the elongated stabilizing base 12 is positioned at this time, the third support base 15 located on the elongated stabilizing base 12 is also positioned. The operator directly pushes the round tube from the operating area 55 towards the third support 15 until it contacts the limiting end plate 17. The limiting end plate 17 restricts the round tube from moving forward. At this time, the position of the round tube to be drilled is exactly below the drilling opening 10. Through this setting, not only can the extended part of the round tube be supported by the third support 15 to improve stability, but also the drilling position of the round tube can be quickly moved below the drilling opening 10 by adjusting the position of the third support 15, which improves the drilling efficiency. The efficiency improvement is particularly obvious when drilling multiple round tubes in the same batch. In addition, the third support 15 not only reduces manufacturing costs, but also reduces the scratches caused by the movement to the surface of the round tube.

[0057] The storage rack 50 on one side of the front half of the control box 1 stores the pipes to be drilled for easy access. The control table 51 is divided into a temporary storage area 53 and an operation area 55 by a support rod 52. The temporary storage area 53 is used to place pipes that have completed some processes or are waiting to be processed. The operator performs pipe positioning, adjustment and other operations in the operation area 55. The window 21 not only facilitates the cleaning of waste, but also facilitates the maintenance of the equipment.

[0058] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
