Problems solved by technology

[0004] However, when the oil pipe is stamped, after the stamped part is stressed and then subjected to the supporting force, the two sides are prone to warping (protrusion), and in the prior art, both ends are directly fixed, but After fixing, it is also necessary to consider the stamping deformation of the oil pipe, and the two sides will be retracted, which will cause damage to both ends of the oil pipe, and it needs to be fixed first, and cannot be fixed during the stamping process;
[0005] In addition, the existing stamping equipment cannot perform multi-stage stamping, let alone combine the process of multi-stage stamping with the fixing of oil pipes. In view of this, the present invention proposes a stamping equipment for anti-bulge oil pipes on both sides

Embodiment 1

[0050] see figure 1 and figure 2 As shown, the purpose of this embodiment is to provide a two-sided anti-bulge oil pipe stamping equipment, including a fuel pipe piece 100 and a stamping device 200 arranged outside the oil pipe piece 100 for stamping it. The stamping device 200 includes an external mechanism 210 and Stamping mechanism 220, external mechanism 210 comprises outer frame 211 and force-bearing support 212, and force-bearing support 212 is arranged on the bottom of outer frame 211, forms insertion cavity between outer frame 211 and force-bearing support 212, during use, oil The pipe 100 is inserted into the cavity and then stamped by a stamping mechanism 220, wherein:

[0051] see image 3 As shown, the stamping mechanism 220 includes a stamping part 221 and a side-end holding part 222. The stamping part 221 includes a primary stamping column 2211, a secondary stamping column 2212, and a stamping head 2213. The primary stamping column 2211 and the secondary stamp...

Embodiment 2

[0057] In order to ensure the force strength of the side pressure frame 2221, please refer to Figure 5 As shown, a pressure member 223 is set between the side pressure frame 2221 and the inner wall of the outer frame 211, please refer to Figure 6 As shown, the pressing part 223 includes a sliding sleeve 2231, the top of the sliding sleeve 2231 is rotatably connected with an adapter seat 2235, and the adapter seat 2235 is fixedly connected with the inner wall of the outer frame 211. The pressing part 223 also includes a sliding column 2232, and the sliding column 2232 It is arranged at the bottom of the sliding sleeve 2231 and is slidably connected with it. A pressurizing spring 2234 is also fixedly connected between the sliding sleeve 2231 and the sliding column 2232. During specific work, the bottom end of the sliding column 2232 is symmetrically provided with a sliding rod 2233, and the side pressure The frame 2221 is a hollow structure, and there are chute 2225 on the inn...

Embodiment 3

[0059] Considering that oil pipes 100 have different thicknesses, but the cross-sections are all circular, the limit strength of the plate structure and rollers is not enough, and it cannot be adjusted according to different thicknesses. For this, please refer to Figure 7 and Figure 8 As shown, the force supporting member 212 includes a support column 2121, the support column 2121 is fixedly connected with the outer frame 211, a shaping wheel 2123 is arranged on the middle position of the support column 2121, and the two sides of the shaping wheel 2123 are symmetrically provided with a force wheel 2122 , between the stressed wheel 2122 and the shaping wheel 2123 and the supporting column 2121 are rotationally connected, the stressed spring 2124 is arranged between the stressed wheel 2122 and the flange at the end of the supporting column 2121, and the stressed spring 2124 is connected to the supporting column 2121 The flange at the end is fixedly connected, and the stressed ...

Abstract

The invention relates to the technical field of oil pipe stamping, in particular to oil pipe stamping equipment capable of preventing protrusions on the two sides. The stamping device is arranged outside the oil pipe fitting and used for stamping the oil pipe fitting, the stamping device comprises an external mechanism and a stamping mechanism, and the external mechanism comprises an outer frame and a stress supporting piece. The stamping range of the stamping head is enlarged in a two-stage stamping mode, so that the deformation distance formed by stamping the oil pipe is increased, the main purpose of first-stage stamping is to reduce the height of the stamping head, the main purpose of second-stage stamping is to stamp the oil pipe, and meanwhile, the stamping efficiency is improved. In the first-stage stamping process, the side pressing spring generates elastic force to act on the side pressing frame, the elastic force acts on the oil pipe fitting through the side pressing frame, in this way, the two sides of the oil pipe can be pressed and limited without fixing the two ends of the oil pipe, the tilting phenomenon is prevented, and therefore utilization in the stamping process is achieved.

Description

technical field [0001] The invention relates to the technical field of oil pipe stamping, in particular to a stamping equipment for anti-bulge oil pipes on both sides. Background technique [0002] Oil pipes are usually used in hydraulic machinery, and their shape is changed by stamping. [0003] Stamping is to rely on presses and molds to apply external force to plates, strips, pipes and profiles, etc., to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to Plastic processing (or pressure processing) is collectively called forging, and the stamping of oil pipes is. [0004] However, when the oil pipe is stamped, after the stamped part is stressed and then subjected to the supporting force, the two sides are prone to warping (protrusion), and in the prior art, both ends are directly fixed, but After fixing, it is also necessary to consider the stamping deformation of the oil pipe, a...
