Problems solved by technology

[0003] When the existing hydraulic riveting machine is riveting some relatively large hardware parts, it is necessary to first control the clamp body on the riveting machine to move to the riveting position, and then drive the movable mold through hydraulic pressure Squeeze to the static mold to flatten the rivet to play a role of fixed connection, but in this way, when riveting, the static mold is generally pressed against one end and the rivet that is kept facing the movable mold end extends for a long period, and the riveting is performed Sometimes, due to the high hydraulic pressure, it is easy to cause the rivet to be affected by the stress, such as tilting or cracking, which reduces the quality of the riveting. At the same time, it takes time to disassemble and re-riveting, which wastes a lot of time and further reduces the riveting efficiency. Moreover, it is necessary to move the pliers continuously during riveting. After the movement, the verticality between the pliers and the hardware is likely to change, which affects the subsequent riveting effect and also reduces the riveting efficiency;
[0004] When riveting, hydraulic pressure is used to control the riveting head to squeeze the rivet, and riveting requires a lot of force to squeeze and deform the rivet to the required Therefore, after riveting once, there will be more or less a certain deformation loss in the riveting head. Although it is small, as the number of riveting increases, the frequency of riveting needs to be replaced will increase, and there will be loss in the riveting head After the error, the distance moved by the hydraulic control is not the actual moving distance on the rivet. At this time, the quantitative movement through the hydraulic control will cause poor riveting effect and lead to unqualified hardware riveting quality.

Abstract

The invention relates to the technical field of riveting machines, and discloses a hydraulic riveting machine for hardware machining, a group of support arms are symmetrically and fixedly mounted on the two sides of a clamp body, a hydraulic balance groove is formed in the top of the clamp body and located between two second hydraulic cavities with the same height, and the middle of the top of the hydraulic balance groove is movably sleeved with a sliding block; a corrugated pipe sleeve is movably connected between the first piston and the inner wall of the first hydraulic cavity, a sliding barrel is fixedly installed at the top of the first piston, a fixing rod with the bottom end extending into the sliding barrel is fixedly installed on the top wall of the first hydraulic cavity, a resistor strip is fixedly installed on the inner wall of the sliding barrel, and a sliding piece in sliding contact with the resistor strip is fixedly installed at the bottom end of the fixing rod. Riveting heads are symmetrically designed at the upper end and the lower end of a clamp body, supporting arms are arranged on the outer sides of the riveting heads, rolling wheels are installed at the ends of the supporting arms in an interactive mode, a sliding block in a hydraulic balance groove is used for controlling on-off of a circuit, a hydraulic system is fed back for adjustment according to resistance changes, and the riveting quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of riveting machines, in particular to a hydraulic riveting machine for hardware processing. Background technique [0002] Hardware processing is to process raw materials (stainless steel, copper, aluminum, iron, etc.) into various parts with lathes, milling machines, drilling machines, polishing machines, etc. according to customers' drawings or samples, among which riveting is also very important. An important step, riveting is rivet connection, which uses axial force to thicken the nail rod in the rivet hole of the part and form a nail head, so as to connect multiple parts, using riveting can quickly connect multiple parts. The strength is generally relatively large, so the existing riveting equipment mostly adopts hydraulic riveting machine, but it still has certain shortcomings: [0003] When the existing hydraulic riveting machine is riveting some relatively large hardware parts, it is necessary to fi...
