Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a positioning and denting device for a metal plate. Background Art

[0002] Dimple of metal sheet is a processing technology, which means forming concave or convex local deformation on metal sheet by specific tools and methods. During the processing and assembly process, when the thickness of the metal sheet does not meet the dimple requirements, or when there are requirements such as connection force during assembly, dimple operation is required.

[0003] Traditional dimple pressing tools are generally made manually, for example, the dimple pressing handle is fixed on a vise, a metal plate is placed on the dimple pressing handle, the head of the dimple pressing handle is inserted into the hole on the metal plate, and then the tail of the dimple pressing handle is hit with a hammer to complete the dimple pressing. However, this method has problems such as uneven hammering force and difficulty in ensuring verticality, which can easily lead to the head of the dimple pressing handle breaking. There are also some improved dimple pressing tools, such as a dimple pressing tool including a rivet handle, a dimple pressing head and a dimple pressing handle. During operation, the dimple pressing handle is fixed by a vise, the workpiece is placed on the dimple pressing handle, and then the rivet gun is used to drive the rivet handle to move, thereby moving the dimple pressing head downward to complete the dimple pressing process. Both of the above methods have the disadvantages of unstable positioning during processing and a high rate of manual intervention. In order to address the above problems, a positioning dimple pressing device for metal plates is proposed herein. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3, a positioning and dimple pressing device for metal plates, the key structure of which includes a base 1. A lifting frame 4 is arranged above the base 1 through two lifting hydraulic cylinders 3. In order to ensure the stability and accuracy of the lifting frame 4 during the up and down movement, a set of stabilizing mechanisms is specially configured to cooperate with the base 1. This stabilizing mechanism is composed of two stabilizing rods 5 carefully arranged on the upper end surface of the base 1, and both stabilizing rods 5 can slide smoothly and unhindered through the lifting frame 4. This design effectively restrains any unnecessary shaking, deviation or tilting that may occur in the lifting frame 4, greatly enhancing the stability and reliability of the operation of the entire device.

[0021] At the bottom of the lifting frame 4, a dimple pressing assembly 11 is carefully installed through an efficient squeezing hydraulic cylinder 10. This assembly can perform dimple pressing operations on metal sheets according to precise settings and requirements.

[0022] On the upper end surface of the base 1, a placement groove 2 is designed for placing the metal sheet to be processed. Two clamping plates 7 are also arranged in this placement groove 2, and their function is to firmly clamp the metal sheet to ensure that the sheet will not be displaced during the processing. Two rotating chambers 12 and a transmission chamber 15 are arranged inside the base 1. In the rotating chamber 12, a screw 13 extending into the transmission chamber 15 is rotatably arranged. The screw 13 is connected to the lifting frame 4 through a transmission mechanism. This transmission mechanism specifically includes a rack 6 firmly connected to the bottom wall of the lifting frame 4. It is worth noting that a gear 16 that cooperates with the rack 6 is arranged on the portion of the screw 13 located in the transmission chamber 15. At the same time, in order to ensure that the rack 6 can run smoothly, an insertion hole 9 that precisely cooperates with the rack 6 is also specially provided on the base 1.

[0023] The screw rod 13 is also effectively connected to the clamping plate 7 through a connecting mechanism. This connecting mechanism mainly includes a nut 14 threadedly sleeved on the screw rod 13. Two connecting rods 8 connected to the clamping plate 7 are installed on the nut 14. When the screw rod 13 rotates, the nut 14 moves along the screw rod 13, thereby driving the clamping plate 7 to clamp or release the metal plate through the connecting rod 8, thereby realizing flexible control of the plate.

[0024] In order to protect the metal sheet from damage during the clamping process to the greatest extent, a protective pad is specially provided on the surface of the clamping plate 7 that contacts the metal sheet. The protective pad is made of a rubber material with good elasticity, flexibility and wear resistance. The rubber material can not only provide effective buffering and reduce the scratches and indentations that may be generated during the clamping process, but also increase the friction force to ensure that the sheet is more stable during clamping.

[0025] In addition, a plurality of support blocks 17 in direct contact with the ground are installed at the bottom of the base 1. These support blocks 17 are all made of antiseptic wood with excellent antiseptic properties. The use of antiseptic wood can not only provide stable and reliable support for the entire device, but also effectively prevent the erosion and damage to the base 1 caused by ground moisture, water and other possible corrosive factors, thereby significantly extending the service life of the equipment and reducing maintenance costs.

[0026] When the utility model is used, first, the metal sheet to be processed is placed in the placement groove 2 on the upper end surface of the base 1. When processing is ready, the lifting hydraulic cylinder 3 is started to push the lifting frame 4 to move up and down along the stabilizing rod 5. During the movement of the lifting frame 4, the rack 6 connected to its bottom wall also moves accordingly. The movement of the rack 6 drives the gear 16 matched with it to rotate, so that the screw 13 located in the rotating chamber 12 and the transmission chamber 15 rotates. As the screw 13 rotates, the nut 14 threadedly sleeved thereon will move axially along the screw 13. The nut 14 drives the clamping plate 7 to move through the connecting rod 8 to clamp the metal sheet in the placement groove 2 to ensure that the sheet will not be displaced during the processing. After the clamping is completed, the extrusion hydraulic cylinder 10 is started to push the dimple assembly 11 to perform a dimple operation on the clamped metal sheet. In the whole process, the rubber protective pad on the clamping plate 7 can not only reduce the damage to the sheet, but also increase the friction to ensure the stability of the clamping. The antiseptic wood support block 17 at the bottom of the base 1 provides stable support for the entire device and effectively resists erosion by factors such as ground moisture.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
