[0001] The invention relates to the technical field of sheet metal processing, in particular to a riveting machine used for sheet metal processing. Background Art

[0002] Sheet metal processing is the process of making metal sheets into products of desired shapes through a series of cold deformation processes. Common processing techniques include shearing, stamping, bending, welding, riveting, etc. Sheet metal products are widely used in the fields of electronics, communications, automotive industry, medical equipment, etc., such as computer cases, mobile phones, car bodies, etc. The riveting equipment is a pressure riveting machine. The pressure riveting machine (also known as a riveting machine, a rotary riveting machine, a riveting machine, a rolling riveting machine, etc.) is a new type of riveting equipment developed based on the principle of cold rolling. It is mainly used to form a rivet head by static pressure upsetting, thereby realizing the connection of parts. The pressure riveting machine has the characteristics of compact structure, stable performance and simple operation, and is widely used in occasions where riveting is required. ‌‌ Traditional riveting machines have poor clamping effect on irregular sheet metal parts (such as uneven ends or special-shaped parts), which can easily lead to riveting offset or deformation.

[0011] The present invention provides a riveting machine for sheet metal processing, which has the following beneficial effects: 1. When the riveting machine for sheet metal processing is used, the vibration motor is started, and the vibration of the vibration motor drives the vibration plate to vibrate, and the vibration of the vibration plate drives the material in the vibration plate to be vibrated out from the discharge pipe. The material falls into the T-shaped feeding trough under the action of inertia, and then the first piston rod begins to extend, and the extension of the first piston rod drives the material to move. When the material moves to the contact range of the second piston rod, the extension of the second piston rod drives the material to move to the retracting component, thereby completing the automatic loading operation, reducing manual intervention and improving work efficiency.

[0012] 2. The riveting machine for sheet metal processing, when in use, after the automatic loading operation, the material falls onto the placement slot, the stamping device is started, and the temperature detection probe begins to detect the temperature of the riveting position below. Since the human body temperature is different from the temperature of the workpiece and the material, it is possible to judge whether it is a workpiece by the temperature, thereby controlling the working state of the stamping device. If it is a workpiece, the third piston rod extends, and the extension of the third piston rod drives the stamping column to move up and down, and the up and down movement of the stamping column drives the magnetic riveting head to move up and down. When the magnetic riveting head presses on the material, it drives the first receiving plate and the second receiving plate to rotate around the first rotating rod and the second rotating rod. The first torsion spring and the second torsion spring generate torque to resist deformation. After the riveting operation is completed, it returns to the initial position, so that it can cooperate with the automatic loading device to automatically receive the material, reducing labor costs and reducing safety hazards. The setting of the temperature detection device avoids injuries caused by accidental touch by humans.

[0013] 3. When using the riveting machine for sheet metal processing, the riveting parameters are input in advance into the PID controller on the stamping device, and then the riveting operation is performed. After the stamping device is started, the third piston rod extends, and the extension of the third piston rod drives the stamping column to move up and down. The up and down movement of the stamping column drives the magnetic riveting head to move up and down. The magnetic riveting head thereby adsorbs the material and moves it to the riveting seat below for riveting operation. When the magnetic riveting head is pressed onto the pressure detection plate, the pressure detection plate moves downward to drive the spring telescopic rod to extend. The extension of the spring telescopic rod squeezes the pressure signal receiving plate. The pressure signal receiving plate receives the signal, so that the punching force can be adjusted according to the maximum pressure that the workpiece can withstand, thereby avoiding damage to the workpiece due to excessive punching force.

[0014] 4. When the riveting machine for sheet metal processing is used, the first motor and the second motor are started. The driving shaft of the first motor rotates to drive the first screw to rotate, and the rotation of the first screw drives the sliding bracket to slide on the first slide rail. The driving shaft of the second motor rotates to drive the second screw to rotate. The rotation of the second screw drives the sliding block to slide on the sliding rod. The sliding of the sliding block drives the sliding of the fixed component. The fixed component clamps and fixes the workpiece, thereby driving the workpiece to move in two axes, making it convenient to move the workpiece to the stamping position, thereby realizing convenient operation.

[0015] 5. When the riveting machine for sheet metal processing is used, the third motor starts to start, and the rotation of the drive shaft of the third motor drives the forward and reverse ball screws to rotate. The rotation of the forward and reverse ball screws drives the connecting rod on the fixed clamp to slide on the second slide rail. The sliding of the connecting rod on the fixed clamp drives the fixed clamp to move. The fixed clamp can clamp and fix workpieces of different regular sizes during the movement, and its fixing effect is better, avoiding riveting deviation or deformation caused by unstable clamping due to traditional manual clamping.
