Embodiment 1

[0021] Embodiment one, see figure 1 , figure 2 , a spring press machine with a horizontal strong press structure, that is, the pressure head 3 is arranged horizontally. The workbench 9 is provided with a concave notch, the depth of which is greater than the radius of the circle formed by the drive disc 5 plus the workpiece string 4, and the two ends of the drive disc 5 are respectively fixed on the two ends of the workbench 9 concave notch by bearing seats. On the other hand, the driving disc 5 is vertically arranged, and 6 workpiece strings 4 are evenly distributed on its circumference, that is, the angle between the 6 workpiece strings 4 is 60 degrees. The drive disc 5 is connected with the speed reducer 6 of the drive device through the brake disc 7 .

[0022] The pressure head 3 is connected on the cylinder 2, and the cylinder 2 is fixed on the cylinder base 1, and the cylinder base 1 is installed horizontally against the concave notch.

[0023] When working, drive the...

Embodiment 2

[0024] Embodiment two, see image 3 , a spring strong press machine with a vertical strong pressing structure, that is, the pressure head 3 is placed vertically. In order to ensure the balanced operation of the rotating drive disc 5, a concave gap is provided on the workbench 9. The drive disc 5 and the workpiece string rod 4 are fixed on both sides of the concave notch of the workbench 9 through the bearing seat, and the drive disc 5 is evenly distributed on the circumference of 6. The workpiece string rod 4, the drive disc 5 is connected with the speed reducer 6 of the driving device through the brake disc 7. The pressure head 3 is connected on the cylinder 2, and the cylinder 2 is fixed on the vertical cylinder base 11, and the bottom of the vertical cylinder base 11 is installed against the end of the concave notch.

[0025] The working process is basically the same as that of the first embodiment, the difference is that the pressure head 3 driven by the cylinder 2 recipr...

Abstract

The invention relates to a spring pressing machine. In order to solve the problem of cold pressing of cylindrical, conical and other compression springs, it includes a workbench and a driving device. It is characterized in that the driving device drives a driving disc, A plurality of workpiece string rods are evenly arranged, and a pressure head is set corresponding to the workpiece string rods. It can pressurize horizontally and vertically, and is positioned by the workpiece string rod to prevent radial movement of the workpiece and ensure compression accuracy; free-fall blanking, various assembly forms; as long as the pressure head or workpiece string rod is replaced, it can be suitable for various specifications The cold and forced compression of cylindrical, conical and other helical compression springs of the model has high efficiency and low labor intensity.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a spring press machine for manufacturing cylindrical and conical helical compression springs. Background technique [0002] The strong press is used to press the spring to enhance its fatigue strength, or for inspection. Existing strong pressing machine is also varied according to the concrete form structure of spring. Such as the patent publication number is CN101966758A a kind of strong pressing machine, adopts the strong pressing mechanism that is made up of strong pressure head-pressure adjusting device-force arm-positioning adjusting device-main rod-universal joint-connecting rod-main eccentric wheel-main shaft; Main shaft - bevel gear set - secondary shaft - secondary eccentric wheel - lever - toggle head - toggle gear - station shaft - station disc - station hole is composed of a toggle mechanism; the main shaft is powered by a motor-reducer . This structur...
