Description

Technical Field

[0001] This application relates to the field of cold shear machine frame technology, specifically a cold shear machine frame. Background Technology

[0002] A cold shear is a piece of equipment used in metal processing, primarily for shearing bar-shaped materials, profiles, or other metal materials. Unlike a hot shear, a cold shear does not require heating the metal during the shearing process; instead, it relies on mechanical force to cut the metal.

[0003] The frame of the cold shear machine is the main supporting structure of the cold shear machine. It is usually made of high-strength materials to withstand the shearing force and vibration generated during operation, and to ensure the stability of the blades, hydraulic system and other components during operation.

[0004] When bar-shaped materials are sheared in a cold shearing machine, a locking device is usually installed to ensure that the round bars are stably sheared inside the cold shearing machine.

[0005] However, when short round bars are cut in a cold shearing machine, the locking device cannot effectively clamp the bars due to the short length of the remaining bars. This causes the ends of the shorter bars to curl up during cutting, making it impossible to cut the shorter bars, affecting cutting efficiency and wasting materials. Therefore, it is necessary to provide a cold shearing machine frame to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a cold shearing machine frame that supports shorter round bars through support components, thereby preventing the shorter round bars from warping during cutting.

[0008] The technical solution adopted by this application to solve its technical problem is: a cold shear machine frame, comprising:

[0009] Bed frame;

[0010] The lower tool holder is located at the lower end of the bed, and a lower shear is installed at the upper end of the lower tool holder. An upper shear is provided on one side of the upper end of the lower shear.

[0011] A support assembly disposed on one side of the lower tool holder, the support assembly having:

[0012] A base plate is installed on one side of the lower tool holder, and fixing posts are installed on both sides of the end of the base plate near the lower tool holder;

[0013] A vertical plate is rotatably connected between the fixed columns. A pipe-laying groove is provided at the upper end of the vertical plate. The vertical plate is located on one side of the upper shears, and the height of the pipe-laying groove is the same as the height of the lower shears.

[0014] Furthermore, the base plate has a first bolt threaded to both ends, a fixing plate is sleeved between the first bolt and the base plate, a connecting hole is opened at the other end of the fixing plate, and a threaded hole is opened on the upright plate. A second bolt is threadedly connected to the threaded hole and the connecting hole.

[0015] Furthermore, placement holes are provided on both sides of the upright plate, the placement holes are adapted to the second bolt, and a handle is fixedly installed on the side of the upright plate away from the lower blade holder.

[0016] Furthermore, a control box is provided on one side of the bed, and a transmission device is provided inside the control box and the bed, which is used to drive the upper scissors to move up and down.

[0017] Furthermore, a locking mechanism is provided on one side of the bed.

[0018] The beneficial effects of this application are: the cold shear machine frame provided by this application is equipped with a support component, so that when the locking mechanism cannot clamp the shorter bar, the support component supports the shorter round bar, preventing the end of the shorter bar from curling up during cutting, thus ensuring cutting efficiency and preventing material waste.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figures 1-2 As shown, this application provides a cold shear machine frame, including a bed 1, a lower blade holder 2 fixedly installed at the lower end of the bed 1, a lower shear 21 fixedly installed at the upper end of the lower blade holder 2, and an upper shear 14 provided on one side of the upper end of the lower shear 21, the upper shear 14 being located inside the bed 1.

[0032] Meanwhile, a control box 11 is provided on one side of the bed 1. In this application, a transmission device 12 is provided inside the control box 11 and the bed 1. The transmission device 12 is used to drive the upper scissors 14 to move up and down. It should be noted that the transmission device 12 is prior art. The transmission device 12 has a high-speed shaft assembly, which is equipped with a brake, a clutch, and a flywheel. The high-speed shaft is driven to rotate by a motor, and the transition shaft is driven by a gear. The transition shaft drives the crank-connecting rod mechanism, and the upper scissors 14 performs the cutting action through the crank-connecting rod mechanism.

[0033] Furthermore, a locking mechanism 13 is provided on one side of the bed 1, which is used to press and lock the pipe to be cold-sheared.

[0034] To facilitate the cutting of shorter round bars, such as Figure 3 As shown, a support assembly 3 is provided on one side of the lower tool holder 2. The support assembly 3 has a base plate 31 fixedly installed on one side of the lower tool holder 2. Fixed columns 32 are fixedly installed on both sides of the base plate 31 near the lower tool holder 2. A vertical plate 33 is rotatably connected between the fixed columns 32. A tube slot 331 is opened at the upper end of the vertical plate 33.

[0035] It should be noted that when the vertical plate 33 is in a vertical state, it is located on one side of the upper scissors 14, and the height of the tube placement groove 331 is the same as the height of the lower scissors 21, so the round bar is placed.

[0036] Meanwhile, a handle 38 is fixedly installed on the side of the upright plate 33 away from the lower tool holder 2, so that the angle of the upright plate 33 can be easily controlled by the handle 38.

[0037] To ensure the stability of the upright plate 33, the two ends of the base plate 31 are threaded with first bolts 35, and a fixing plate 34 is sleeved between the first bolts 35 and the base plate 31. The other end of the fixing plate 34 is provided with a connecting hole 37. At the same time, the upright plate 33 is provided with a threaded hole 333. In this application, when the threaded hole 333 and the connecting hole 37 correspond to each other, the threaded hole 333 and the connecting hole 37 are internally threaded with a second bolt 36.

[0038] Furthermore, the upright plate 33 is provided with placement holes 332 on both sides. The placement holes 332 are adapted to the second bolt 36. When the second bolt 36 is not in use, it is temporarily placed into the placement holes 332.

[0039] In summary: When cutting a long circular bar, the second bolt 36 should be removed and placed in the placement hole 332, as follows: Figure 4 As shown, at this time, the fixing plate 34 is retracted to be parallel to the base plate 31, and the upright plate 33 is adjusted downward to be parallel to the base plate 31 by the handle 38, so as not to affect the collection and transmission of the finished product after cutting.

[0040] When cutting shorter round bars, manually adjust the vertical plate 33 to be vertical and rotate the fixing plate 34 until the connecting hole 37 corresponds to the threaded hole 333. Then, take out the second bolt 36 in the placement hole 332 and thread it into the threaded hole 333 to fix and support the vertical plate 33. Then, place the shorter round bar on the tube groove 331 and the lower shear 21, and start the transmission device 12 to drive the upper shear 14 to cut the shorter bar. When the locking mechanism 13 cannot clamp the shorter bar, the support component 3 supports the shorter round bar to prevent the end of the shorter bar from lifting during cutting, thus ensuring cutting efficiency and preventing material waste.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
