Description

Technical Field

[0001] The utility model relates to the technical field of steel sleeve processing, in particular to an anti-extrusion steel sleeve product processing jig. Background Art

[0002] Steel sleeves can be made into various oil grooves and oil holes inside and outside. Through machining, heat treatment and other processes, the products are more wear-resistant and impact-resistant, with good product strength and long service life. The manufacturing of steel sleeve products mainly uses surface treatment processes such as stamping, rolling, machining, and electroplating. The stamping process requires the use of molds to form. This processing method mainly realizes the processing of the shape of the object by changing the physical state of the formed material.

[0003] During the processing and forming of existing products with steel sleeves, if there is an offset between the mold and the steel sleeve, the mold is easily squeezed and damaged, which not only increases the cost but also reduces the production efficiency; and the existing mechanism for clamping the steel sleeve is complicated and troublesome to operate. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide an anti-extrusion steel sleeve product processing jig, which can quickly clamp the steel sleeve by means of a clamping mechanism. The steel sleeve is first placed on a placement block, and then the handle is turned to rotate the threaded rod, and then the four bevel gears are meshed and driven to rotate the four threaded rods at the same time, and the four slide blocks slide toward the steel sleeve along the slide groove at the same time until the steel sleeve is clamped. Not only is the clamping effect good, but also steel sleeves of different diameters can be clamped; the anti-extrusion mechanism can prevent the upper mold from being pressed against the steel sleeve. When the lower mold is closed, the position of the steel sleeve deviates from the upper mold, causing the device to be squeezed and damaged. When it is necessary to check whether the clamping mechanism has deviations, the upper mold is lowered. If there is a deviation, the bottom end of the upper mold will first contact the anti-extrusion plate and move downward to compress the second spring. When the pressure rod follows the anti-extrusion plate and moves downward for a certain distance, the bottom end of the pressure rod will touch the stop switch to stop the hydraulic rod from extending. Then the position of the upper mold on the mounting seat is adjusted to ensure that the upper mold just passes through the limit hole when it descends to close the mold, avoiding damage to the device caused by squeezing the upper and lower molds.

There are four bevel gears 9 and they mesh with each other. The outer surface of the threaded rod 4 is rotatably connected to the lower mold 2, and the end of the threaded rod 4 away from the bevel gear 9 is fixedly connected with a handle 10. When clamping the steel sleeve, first place the steel sleeve on the placement block 3, and then rotate the handle 10 to rotate the threaded rod 4, and then the four bevel gears 9 mesh and transmit, so that the four threaded rods 4 rotate at the same time, and the four sliders 6 slide along the slide groove 5 toward the steel sleeve at the same time until the steel sleeve is clamped. Not only is the clamping effect good, but also steel sleeves of different diameters can be clamped. When the mold is closed, the clamping plate 8 will compress the first spring 7 and enter the inside of the slider 6 to avoid affecting the mold closing effect.

[0023] A first protrusion 17 is fixedly connected to the side surface of the base 1, a guide rod 18 is fixedly connected to the upper surface of the first protrusion 17, a second protrusion 19 is slidably connected to the outer surface of the guide rod 18, a mounting seat 21 is fixedly connected to the side surface of the second protrusion 19, an upper mold 22 is fixedly connected to the lower surface of the mounting seat 21, a hydraulic rod 23 is fixedly connected to the upper surface of the mounting seat 21, a third spring 20 is fixedly connected to the upper surface of the first protrusion 17, and the top of the third spring 20 is fixedly connected to the second protrusion 19. The hydraulic rod 23 extends under the action of the hydraulic cylinder to push the mounting seat 21 and the upper mold 22 to move downward until the upper mold 22 and the lower mold 2 are molded together. The guide rod 18 is used to improve the stability of the upper mold 22 when it descends. When the mold is closed, the third spring 20 plays a certain buffering role.

[0024] An anti-extrusion mechanism is arranged above the lower mold 2, and the anti-extrusion mechanism includes an anti-extrusion plate 11, a pressure rod 12, a second spring 13 and an emergency stop switch 14. A circular hole groove is arranged on the upper surface of the lower mold 2, and the bottom inner wall of the circular hole groove is fixedly connected to the second spring 13, and the top of the second spring 13 is fixedly connected to the anti-extrusion plate 11, and the lower surface of the anti-extrusion plate 11 is fixedly connected to the pressure rod 12, and the bottom inner wall of the circular hole groove is fixedly connected to the emergency stop switch 14. A limiting hole 16 is arranged on the outer surface of the anti-extrusion plate 11. When the upper mold 22 is lowered for mold closing, when the clamping mechanism clamps the steel sleeve, as long as the steel sleeve is located just below the limiting hole 22 The lower mold 22 passes through the limiting hole 16 to process the steel sleeve on the placement seat 3. In order to check whether there is a deviation between the steel sleeve and the upper mold 22, the hydraulic rod 23 is extended to lower the upper mold 22. When a deviation occurs, the bottom end of the upper mold 22 will contact the anti-extrusion plate 11 and move downward to compress the second spring 13. When the pressure rod 12 moves downward a certain distance following the anti-extrusion plate 11, the bottom end of the pressure rod 12 will touch the stop switch 14 to stop the hydraulic rod 23 from extending and adjust the position of the upper mold 22 on the mounting seat 21 to avoid damage to the device caused by the extrusion of the upper mold 22 and the lower mold 2.

[0025] A countersunk hole is provided on the upper surface of the anti-extrusion plate 11, and a fixing bolt 15 is provided inside the countersunk hole. The stud of the fixing bolt 15 passes through the anti-extrusion plate 11 and extends into the interior of the pressure rod 12. The fixing bolt 15 is used to install the pressure rod 12 on the anti-extrusion plate 11, which facilitates the disassembly of the anti-extrusion plate 11.

[0026] Working principle: When the steel sleeve needs to be processed, first place the steel sleeve on the placement block 3, then turn the handle 10 to rotate the threaded rod 4, and then the four bevel gears 9 are meshed and transmitted to make the four threaded rods 4 rotate at the same time, and the four sliders 6 slide along the slide groove 5 toward the steel sleeve at the same time until the steel sleeve is clamped. Not only is the clamping effect good, but also steel sleeves of different diameters can be clamped. When the clamping mechanism clamps the steel sleeve, as long as the steel sleeve is located directly below the limiting hole 22, it means that the processing position is correct. The lower mold 22 passes through the limiting hole 16 to process the steel sleeve on the placement seat 3. In order to check whether there is a deviation between the steel sleeve and the upper mold 22, the hydraulic rod is extended. 23 makes the upper mold 22 descend. When deviation occurs, the bottom end of the upper mold 22 will contact the anti-extrusion plate 11 and move downward to compress the second spring 13. When the pressure rod 12 moves downward a certain distance following the anti-extrusion plate 11, the bottom end of the pressure rod 12 will touch the stop switch 14 to stop the hydraulic rod 23 from extending and adjust the position of the upper mold 22 on the mounting seat 21 to avoid damage to the device caused by the squeezing of the upper mold 22 and the lower mold 2. Then the hydraulic rod 23 extends under the action of the hydraulic cylinder, pushing the mounting seat 21 and the upper mold 22 to move downward, and the lower mold 22 passes through the limiting hole 16 until the upper mold 22 and the lower mold 2 are completely molded.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
