Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Features in the embodiments described below may be combined with each other without conflict.
The first embodiment is as follows:
as shown in fig. 1 and 2, the portable riveting machine for riveting color steel plates of the present invention comprises a machine body and a holding portion 3, wherein the holding portion 3 is arranged on the machine body; the machine body comprises a rack 1, and a clamp body 5, a movable riveting die 8, a fixed riveting die 7, a demoulding sleeve 9 and a driving device which are arranged on the rack 1; the driving device is a gas-liquid pressure cylinder 2 arranged at the rear end of the frame 1; the clamp body 5 is fixedly arranged on the rack 1, the fixed riveting die 7 is fixedly arranged on the clamp body 5, and the movable riveting die 8 and the fixed riveting die 7 are oppositely arranged; the movable riveting die 8 is in transmission connection with the driving device and is driven to do linear reciprocating motion in the demolding sleeve 9 so as to punch the color steel plate to form a riveting structure without riveting; the demolding sleeve 9 is fixedly arranged at the front end part of the frame 1; the fixed riveting die 7 is provided with a die cavity, and the movable riveting die 8 is provided with a punch head matched with the die cavity.
As shown in fig. 1 and 2, the pincer body 5 is C-shaped, and extends from the frame 1 to the opposite side of the movable riveting die 8 to form a supporting end for installing the fixed riveting die 7, and the fixed riveting die 7 is fixedly installed on the supporting end through a hexagon socket head cap screw; the output end of the gas-liquid pressure cylinder 2 is a push rod which does linear reciprocating motion, the push rod is coaxially and fixedly connected with the movable riveting die 8, and the movable riveting die 8 is pushed to stretch into the die cavity of the fixed riveting die 7 so as to punch and form the color steel plate.
In addition, it should be noted that the demolding sleeve 9 is a cylinder provided with a through hole for the dynamic riveting die 8 and the push rod to pass through, and the outer diameter of the demolding sleeve 9 is 4 times of the aperture of the through hole, that is, the demolding sleeve 9 has a larger supporting area for the color steel plate when the dynamic riveting die 8 is demolded, and the supporting area can provide a larger supporting force to better separate the color steel plate from the dynamic riveting die 8; in addition, this drawing of patterns sleeve 9 accessible hexagon socket head cap screw is fixed on frame 1, and it pass the hole with the push rod is in order to make the better colored steel sheet of punching press of dynamic riveting mould 8 with dynamic riveting mould 8 clearance fit.
In addition, in this embodiment, the gap between the rivet fixing die 7 and the demolding sleeve 9 is 5.0 times the thickness of the color steel plate to be riveted. When the thickness of the color steel plate to be riveted is 2.0mm, the gap between the fixed riveting die 7 and the demolding sleeve 9 is 10mm, and when the gap exists, the stamping stroke of the movable riveting die 8 needs to be set firstly, namely, the movable riveting die 8 can just stamp the color steel plate into the die cavity of the fixed riveting die 7 without damaging equipment and the color steel plate; secondly, when the gap exists, the gap distance between the color steel plate and the demolding sleeve 9 is 6mm, and the color steel plate is still in the elastic deformation range under the distance, so that if the gap distance is excessively increased, the color steel plate can be damaged due to plastic deformation; furthermore, the gap needs to be considered for the portable riveting machine to be put into or taken out of the doorframe, so the gap cannot be less than 6 mm.
It should be noted that the gas-liquid pressure cylinder 2 is only an embodiment of the present invention, and the gas-liquid pressure cylinder 2 is integrated with a pressure cylinder and a pressure cylinder, and uses a simple gas pressure as a power source, and works by utilizing the sectional area ratio of the large and small pistons of the pressure booster and the pascal energy balance principle, and increases the low pressure of the gas pressure by tens of times to supply to the oil pressure cylinder, thereby completing the operation. When the riveting die works, the pressurizing oil cylinder moves firstly, the hydraulic oil drives the piston rod to abut against a workpiece, the pressurizing air cylinder moves after the piston rod is in place, the pressurizing piston moves downwards to extrude hydraulic oil in the prepressing cavity by pushing of compressed air, the hydraulic oil expands, and high pressure is generated to achieve the aim of riveting forming. So that the push rod pushing the output end of the riveting device can reciprocate to complete the riveting work.
In addition, it should be noted that the gas-liquid pressure cylinder 2 can rivet a steel plate with a thickness of 2mm in a limited space, and correspondingly, the volume of the riveting machine can be reduced correspondingly. In particular, for the C-shaped portion which may protrude into the door frame, the maximum height of the caliper body 5 is 64mm and the maximum width thereof is 65 mm.
