Description

Technical Field

[0001] The utility model relates to the technical field of upsetting processing, in particular to a large-scale transverse upsetting device. Background Art

[0002] In construction projects, when connecting steel bar heads, in order to ensure that the strength of the steel bar connection is not lower than the strength of the parent steel bar, that is, to meet the equal strength connection requirements, the steel bar head needs to be upset so that the diameter of the upset part is increased to be larger than the diameter of the parent material, and then the upset part is threaded with a matching special threading machine, and then the threaded parts of the two processed steel bar heads are connected with a wrench using a sleeve of the same specification, thus completing the so-called steel bar butt connection.

[0003] The upsetting machines in the existing technology generally use single-cylinder hydraulic cylinders. Although they can meet the national standard requirements, the upsetting pressure is insufficient. After long-term use, both the pressure and the pressure are insufficient, resulting in poor upsetting forming quality and a high defective product rate, which reduces production efficiency and production quality. It cannot be promoted for use on non-standard steel bars with the same diameter and higher strength. For this reason, the utility model proposes a large-scale transverse upsetting equipment to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1 As shown in the figure, the utility model provides a technical solution: a large-scale transverse upsetting equipment, including: a workbench 1, a hydraulic system 2, a clamping device 3, and a placement rack 4.

[0021] Specifically, a workbench 1 is provided with a hydraulic system 2, which includes an upsetting hydraulic press 21, an auxiliary hydraulic press 22, and a pressure transmission device 23. The upsetting hydraulic press 21 and the auxiliary hydraulic press 22 are arranged in opposite directions, and the auxiliary hydraulic press 22 is arranged on both sides of the upsetting hydraulic press 21. The hydraulic system 2 is used for hydraulic upsetting of the workpiece. By setting the upsetting hydraulic press 21 and the auxiliary hydraulic press 22 in opposite directions, the pressure transmission device 23 can combine and transmit the pressure of the auxiliary hydraulic press 22 to the upsetting hydraulic press 21. 1 is provided with a clamping device 3, which includes a base 31 and a clamping hydraulic press 32. The base 31 is "concave" and is fixedly mounted on the workbench 1. The clamping device 3 is used to clamp the workpiece during upsetting to avoid bending of the workpiece due to excessive pressure during upsetting. The hydraulic system 2 and the clamping device 3 are connected at both ends through the auxiliary hydraulic press 22. The auxiliary hydraulic press 22 is set on one side of the clamping device 3 to save space. A placement rack 4 is fixedly welded on the workbench 1 for placing the workpiece during processing to facilitate processing.

[0022] In order to facilitate the pressure conversion of the hydraulic press, the pressure transmission device 23 of the present application is fixedly installed on the workbench 1. One side of the pressure transmission device 23 is connected to the hydraulic cylinder of the upsetting hydraulic press 21. The pressure transmission device 23 and the upsetting hydraulic press 21 are integrated into one. The integrated design of the upsetting hydraulic press 21 and the pressure transmission device 23 enhances the air tightness of the device and avoids insufficient pressure caused by pressure loss due to poor air tightness of the device.

[0023] In order to provide sufficient hydraulic pressure, the auxiliary hydraulic machine 22 of the present application is fixed to one side of the base 31 by bolts. The hydraulic rod of the auxiliary hydraulic machine 22 is connected to the pressure transmission device 23 by piston movement. The auxiliary hydraulic machine 22 transmits pressure to the pressure transmission device 23 through the piston movement of the hydraulic rod. The pressure transmission device 23 combines the pressure through pressure conversion. The pressure auxiliary hydraulic machine 22 is provided with an oil inlet and an oil return port. The auxiliary hydraulic machine 22 realizes the circulation of hydraulic oil through the oil inlet and the oil return port.

[0024] In order to facilitate the disassembly and replacement of the first fixed plate groove 33, a first fixed plate groove 33 is provided in the groove of the base 31 of the present application. The first fixed plate groove 33 is fixed in the groove of the base 31 by a countersunk screw, and the clamping hydraulic press 32 is fixedly connected to the second fixed plate groove 34 by a countersunk screw. The second fixed plate groove 34 is the same size as the first fixed plate groove 33 and is correspondingly arranged. The corresponding cooperation between the second fixed plate groove 34 and the first fixed plate groove 33 clamps the workpiece that needs to be upset. The connection method of the countersunk screw does not affect the clamping effect while facilitating disassembly. Fixed plate grooves of different sizes can be replaced to correspond to workpieces of different sizes.

[0025] In order to firmly clamp the workpiece during processing, a countersunk hole is provided on the first fixed plate groove 33 of the present application, and a semicircular groove with the same length as the plate surface is provided at the center line position of the first fixed plate groove 33. The setting of the semicircular groove facilitates the corresponding cooperation between the first fixed plate groove 33 and the second fixed plate groove 34 to clamp the upsetting workpiece.

[0026] In order to extrude and upset the workpiece, the end face of the pressure rod of the upsetting hydraulic press 21 of the present application is provided with an upsetting plate groove 211, and the upsetting plate groove 211 is fixed to the end face of the hydraulic rod of the upsetting hydraulic press 21 by bolts. A circular groove is provided in the center of the upsetting plate groove 211, and the upsetting plate groove 211 is used to extrude and upset the workpiece. The circular groove is designed to limit the size of the upsetting workpiece, avoid over-upsetting, protect the workpiece, and avoid bending of the workpiece. The bolt-fixed connection method can replace the upsetting plate groove 211 of different sizes as needed.

[0027] In order to facilitate the placement of workpieces during processing, the placement rack 4 of the present application is arranged at the center of the workbench 1. The placement rack 4 includes a column, a clamping frame and a roller 5. The column and the clamping frame are an integrated structure. The clamping frame is "concave" in shape. Holes are opened on both sides of the clamping frame. The bearings of the roller 5 are fixed in the holes on both sides of the clamping frame. The placement rack 4 is used to place the workpiece and align it with the fixed plate groove during upsetting processing. The design of the roller 5 makes it easy to push the workpiece into the clamping device 3.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
