Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder manufacturing technology, specifically a device for roughing and hot working of hydraulic cylinder barrel. Background Technology

[0002] In the production process of hydraulic cylinder barrels, it is usually necessary to go through working steps such as upsetting and hot working. First, the pipe end or the whole section is "upset" in the mold, so that the metal fibers are redistributed and the wall thickness at the end or middle is increased, leaving enough allowance for subsequent processing. Then, high temperature quenching and hardening are carried out. This process refines the grains, so that the cylinder barrel can obtain a matrix hardness of about 25-30 HRC, while maintaining sufficient toughness.

[0003] The current processing method is a production line consisting of multiple machines to turn ordinary seamless steel pipes into high-strength, high-wear-resistant cylinder blanks. It requires processing by various machines and multiple transfers to change processing equipment. There is still room for improvement in overall work efficiency. Utility Model Content

[0010] Furthermore, the base plate has support frames fixedly installed on both sides of its bottom edge, and the hydraulic rod output end has a punch head fixedly installed relative to it via a flange.

[0011] Furthermore, electric actuators are fixedly inserted and installed on both sides of the substrate, and the output end of the electric actuator is fixedly connected to a hanger, which is fixedly installed on the upper edge of both sides of the protective shell.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 In this embodiment of the present invention, a hydraulic cylinder barrel upsetting and hot working hardening device includes a stamping upsetting structure 1, a limiting clamping structure 2, and a quenching structure 3. The stamping upsetting structure 1 includes a base plate 101, a hydraulic rod 103 fixedly installed in the middle of the base plate 101, a protective shell 107 suspended at the bottom of the base plate 101, and an induction coil 108 embedded inside the protective shell 107. The limiting clamping structure 2 includes a replaceable clamp 207, which is movably installed below the base plate 101. The quenching structure 3 includes a base 301, which is fixedly installed at the bottom of the limiting clamping structure 2, and a quenching pool 303 is clamped in the middle of the base 301.

[0026] Specifically, the cylinder barrel is first clamped and limited using the replaceable clamp 207. The protective shell 107 is lowered, and the cylinder barrel is softened by induction heating using the induction coil 108. Then, the induction coil 108 is turned off, and the hydraulic rod 103 is used for stamping and upsetting. Then, the limiting clamping structure 2 is opened, allowing the high-temperature cylinder barrel to fall directly into the quenching tank 303, which contains quenching oil. The cylinder barrel is then directly quenched and hardened, integrating heating, upsetting, and quenching into one process and eliminating the need for other steps, thus greatly improving the efficiency of the entire process.

[0027] Example 1

[0028] like Figure 1 , 2As shown, in this embodiment, support frames 102 are fixedly installed on both sides of the bottom of the substrate 101, and a punch head 104 is fixedly installed at the output end of the hydraulic rod 103 via a flange; electric push rods 105 are fixedly inserted on both sides of the substrate 101, and hangers 106 are fixedly connected to the output end of the electric push rods 105, and hangers 106 are fixedly installed on the upper edges of both sides of the protective shell 107.

[0029] In this embodiment, the stamping head 104 is designed to be replaceable, which can meet the upsetting requirements of different cylinder models. At the same time, the lifting and lowering of the protective shell 107 is controlled by the electric push rod 105 pulling the hanger 106. The limit clamping structure 2 is made of austenitic stainless steel, which ensures the pressure bearing strength while avoiding induction heating by the induction coil 108. It is also designed to be lifting, just like the stamping head 104, so that it is not at the same height as the stamping head 104 and avoids affecting the stamping head 104.

[0030] like Figure 1 , 4 As shown, in this embodiment, a shaft seat 201 is fixedly installed on the front and rear edges of the upper surface of the base 301, a pool body slot 302 is opened at the bottom of the base 301, the quenching pool 303 is inserted into the pool body slot 302, an inclined chute 304 is fixedly installed on the front side of the quenching pool 303, and a discharge conveyor belt 305 is fixedly installed on the upper surface of the inclined chute 304.

[0031] In practice, after quenching is completed, the discharge conveyor belt 305 is started. The lower half of the discharge conveyor belt 305 directly covers the bottom of the quenching pool 303, which can directly pull out the cylinder that has fallen into the quenching pool 303 and transport it to the next processing equipment such as the cleaning equipment.

[0032] Example 2

[0033] Based on Embodiment 1, in order to supplement the specific clamping method of the cylinder barrel by the limiting clamping structure 2, which was not mentioned in Embodiment 1.

[0034] like Figure 1 , 3 As shown, in this embodiment, there are two replaceable clamps 207, which are respectively fixedly clamped in two clamp mounting seats 206. The clamp mounting seats 206 are opened on the upper surface of the force seat 205, and the force seat 205 is fixedly installed on the upper surface of the sliding seat 204. The two ends of the two sets of sliding seats 204 are respectively screwed to the two ends of two bidirectional lead screws 202. An external toothed ring 203 is fixedly sleeved in the middle of the bidirectional lead screw 202, and the middle of the bidirectional lead screw 202 is rotatably connected to the shaft seat 201. A synchronizer 306 is fixedly installed on the upper edge of one side of the base 301. A drive motor 307 is embedded in the front and rear edges of the upper side of the base 301. A gear 308 is fixedly installed at the output end of the drive motor 307, and the gear 308 meshes with the external toothed ring 203.

[0035] In practice, the synchronizer 306 synchronously controls two sets of drive motors 307 to rotate gears 308, which in turn rubs the external gear ring 203 to control the rotation of two bidirectional lead screws 202, thereby rubbing the two sets of external gear rings 203 to slide in opposite directions synchronously. This, combined with the replaceable clamp 207, clamps and limits the cylinder. Alternatively, after the upsetting is completed, the cylinder can be directly unfolded and released, allowing it to fall directly into the quenching pool 303.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
