Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of production of support rod housings, and specifically relates to a production process for gas strut housings. Background Art
[0002] A support rod is a rod with a supporting effect and is widely used in the home and furniture fields. The support rod housing is an important protective component in the support rod;
[0003] In the production process of the support rod housing in the prior art, it is necessary to cut the original rod into the required length, and a set of mounting screws need to be welded at one end of the housing after cutting. However, there are still certain deficiencies in the cutting process and welding process in the prior art;
[0004] In the prior art during cutting, the two ends of the cut pipe body are of the same size. In the prior art during welding, manual welding is generally used. If the opening at one end of the cut pipe body is too large, it may affect the subsequent welding of the screws, and when the opening at one end of the pipe body is too large, during the subsequent welding process of the screws, the welding repair may be incomplete due to the large opening, and incomplete welding repair may easily cause the loosening and falling off of the screws. Summary of the Invention

[0008] To solve the above problems, the present invention adopts the following technical solutions.
[0009] A production process for gas strut housings includes a stretching step and a welding step, and the specific process steps are as follows:
[0010] Step 1: Feed the electrolytic plate into the feeding module for feeding;
[0011] Step 2: Cut the electrolytic plate fed in Step 1 using the cutting module;
[0012] Step 3: Transport the cut electrolytic plate in Step 2 to the stretching module and output it after multiple stretches;
[0013] Step 4: Pour the stretched finished housing into the feeding module;
[0014] Step 5: Use the lifting module to lift and place the finished housing in the feeding module;
[0015] Step 6: Use the clamping module to clamp and install the placed finished shell on the welding module;
[0016] Step 7: Use the feeding module to place screws on the finished shell in Step 6;
[0017] Step 8: Use the welding head on the welding module to weld the screws to the finished shell;
[0018] Step 9: After quality inspection, store out of the warehouse.
[0019] Preferably, the specific steps of the multiple stretching in Step 3 include:
[0020] S1: Use the first cold drawing module to perform primary stretching on the electrolytic plate to obtain a prototype shell;
[0021] S2: Use the conveying module to send the prototype shell after primary stretching under the second cold drawing module, and use the second cold drawing module to perform secondary stretching on the prototype shell to obtain a secondary stretched shell;

[0024] S5: Use the conveying module to send the quaternary stretched shell under the fifth cold drawing module, and use the fifth cold drawing module to perform quinary stretching on the quaternary stretched shell to obtain a quinary stretched shell;
[0025] S6: Use the conveying module to send the quinary stretched shell under the sixth cold drawing module, and use the sixth cold drawing module to perform senary stretching on the quinary stretched shell to obtain a senary stretched shell;
[0026] S7: Use the conveying module to send the senary stretched shell under the seventh cold drawing module, and use the sixth cold drawing module to perform final stretching on the senary stretched shell to obtain the finished shell.
[0027] Further, during the final stretching in Step S7, shell cutting is also required, and the specific steps are as follows:
[0028] S701: Use the conveying module to convey the finished shell after final stretching into the cutting module;
[0029] S702: Use the cutting module to cut off the curled edge on the finished shell.
[0030] Further, the sensor component module includes a first pressure sensor, a temperature sensor, a second pressure sensor, a flow sensor, a third pressure sensor, a fourth pressure sensor, and a fifth pressure sensor;

[0044] Further, before the feeding module places the screws on the finished product housing, it is also necessary to preprocess the pipe orifice of the finished product housing, which specifically includes: cleaning the pipe orifice of the finished product housing by using the dust suction module.
[0045] Further, the welding temperature in the step eight is 150 - 250 °C.
[0046] Beneficial Effects
[0047] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0048] (1) The production process in the present invention can stretch the electrolytic plate into the required length by performing seven cold draws after cutting the electrolytic plate. And during the last draw, the finished shell is cut, and the pipe orifice is compressed and pressed during the cutting process, and an inner groove is formed after pressing. The inner groove formed by pressing saves the time of full sealing. At the same time, the inner groove formed by pressing matches the screw, so that during the subsequent screw welding process, it is convenient for the welding head to perform laser welding, and it is more beneficial for the screw to bear the weight.
[0049] By using a laser welding head to weld the screw on the inner groove, manual welding is no longer required, reducing the production cost. At the same time, the design of the inner groove on the pipe body is adopted to solve the problem that the welding repair is incomplete due to too large an opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Step 3: Transport the cut electrolytic plate in Step 2 to the stretching module, and output it after multiple stretches.
[0060] Step 4: Pour the stretched finished housing into the feeding module.
[0061] Step 5: Use the lifting module to lift and place the finished housing in the feeding module.
[0062] Step 6: Use the clamping module to clamp and install the placed finished housing on the welding module.
[0063] Step 7: Use the feeding module to place screws on the finished housing in Step 6.
[0064] Step 8: Use the welding head on the welding module to weld the screws to the finished housing.
[0065] Step 9: After quality inspection, store it out of the warehouse.
[0066] The specific steps of the multiple stretches in Step 3 of the production process include:
[0067] S1: Use the first cold drawing module to conduct the initial stretch on the electrolytic plate to obtain a prototype housing.
[0068] S2: Use the conveying module to send the prototype housing after the initial stretch under the second cold drawing module, and use the second cold drawing module to conduct the second stretch on the prototype housing to obtain a second-stretched housing.
[0069] S3: Use the conveying module to send the second-stretched housing under the third cold drawing module, and use the third cold drawing module to conduct the third stretch on the second-stretched housing to obtain a third-stretched housing.
[0070] S4: Use the conveying module to send the third-stretched housing under the fourth cold drawing module, and use the fourth cold drawing module to conduct the fourth stretch on the third-stretched housing to obtain a fourth-stretched housing.
[0071] S5: Use the conveying module to send the fourth-stretched housing under the fifth cold drawing module, and use the fifth cold drawing module to conduct the fifth stretch on the fourth-stretched housing to obtain a fifth-stretched housing.
[0072] S6. Use the conveying module to send the five - times - stretched outer shell under the sixth cold - drawing module, and use the sixth cold - drawing module to perform the sixth stretch on the five - times - stretched outer shell to obtain a six - times - stretched outer shell;
[0073] S7. Use the conveying module to send the six - times - stretched outer shell under the seventh cold - drawing module, and use the seventh cold - drawing module to perform the final stretch on the six - times - stretched outer shell to obtain the finished outer shell.
[0074] During the final stretch in production process step S7, the outer shell also needs to be cut. The specific steps are as follows:
[0075] S701. Use the conveying module to transport the finished outer shell after the final stretch into the cutting module;
[0076] S702. Use the cutting module to cut off the curled edge on the finished outer shell.

And during the last stretch, the finished outer shell is cut, and during the cutting process, the pipe opening is compressed and pressed, and an inner groove is formed after the pressing. Through the inner groove formed by the pressing, the time for full sealing is saved. At the same time, the inner groove formed by the pressing matches the screws, so that during the subsequent screw welding process, it is convenient for the welding head to perform laser welding, and it is more beneficial for the load - bearing of the screws.
