Description

Technical Field

[0001] The utility model relates to the technical field of welding rod processing, in particular to a straightening and cutting machine used for processing electric welding rods. Background Art

[0002] The welding rod used in manual arc welding consists of two parts: a coating and a core. The core is the metal core of the welding rod, and the core varies with different types of welding rods. When the welding rod is produced, the coating (coating) is usually evenly and centripetally pressed onto the core.

[0003] In the existing technology, when producing welding rods, the welding core raw material may be bent. If it is not straightened, the final welding rod will be unqualified. The existing straightening equipment used in welding rod processing requires a lot of effort to align the welding core with the groove of the straightening component. Moreover, at room temperature, the ductility of the metal welding core is low, and the straightening effect is not good. Therefore, we propose a straightening and cutting machine for electric welding rod processing. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a straightening and cutting machine for electric welding rod processing, which has a reliable welding core straightening unit. The welding core placed inside the metal material trough will automatically slide to the bottom of the trough under the action of gravity, so that when the pressure rod is pressed tightly inside the metal material trough, the welding core can be stuck in the inside of the clamping groove and pressed and straightened; under the action of the heater, the metal material trough transfers the temperature to the welding core, thereby improving the ductility of the welding core and being more conducive to the straightening operation; it also has a reliable cutting and pushing unit, which can cut off the end of the welding core and can push the welding core section left in the metal material trough after cutting outwards a certain distance, so that workers can receive the material on the right side, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a straightening and cutting machine for welding rod processing, comprising a base, a welding core straightening unit and a cutting and pushing unit;

[0006] Base: A square plate with a mounting bracket fixedly connected to the middle position of the rear side of the upper end. The mounting bracket is an inverted L-shaped structure.

[0007] The welding core straightening unit comprises a lifting and lowering pressure plate, a pressure rod, a clamping slot, a processing table, a metal material trough and a heater. The middle part of the upper end of the base is fixedly connected to a horizontal processing table, and a longitudinal row of mounting slots is opened in a linear array on the upper end of the processing table. A metal material trough is fixedly installed inside the mounting slot. The metal material trough is an arc-shaped structure of half a circle, and a heater is installed at the bottom of the metal material trough. The hot end of the heater is in contact with the bottom of the metal material trough. A lifting and lowering pressure plate is hoisted on the lower side of the horizontal end of the mounting frame. A longitudinal row of pressure rods is fixedly connected to the linear array on the lower side of the lifting and lowering pressure plate. Each horizontal pressure rod vertically corresponds to the mounting slot on the upper end of the processing table. The cross-section of the lower end of the pressure rod is a raised structure of half a circle, and a horizontal clamping slot is opened at the lower end of the raised structure.

[0008] Cutting and pushing unit: installed on the left and right sides of the processing table.

[0009] The mounting frame is used for the installation of the hydraulic cylinder, which is used to drive the lifting and lowering pressure plate to move up and down. After the lifting and lowering pressure plate drops to the bottom, the pressure rod is inserted into the mounting groove on the upper end of the processing table. The circular protrusion on the lower side of the pressure rod is tightly pressed against the inner side of the metal trough. The welding core placed inside the metal trough will automatically slide to the bottom of the trough under the action of gravity, so that when the pressure rod is pressed tightly against the inside of the metal trough, the welding core can be stuck in the inside of the slot and be pressed and straightened; under the action of the heater, the metal trough transfers the temperature to the welding core, thereby improving the ductility of the welding core and making it more conducive to straightening operations; the cutting and pushing unit is used to cut off the end of the welding core, and can push outward the welding core segment left in the metal trough after cutting, so that workers can take out the material.

[0010] Furthermore, the weld core straightening unit further includes a hydraulic cylinder and a connecting slide. The hydraulic cylinder is mounted vertically on the upper horizontal end of the mounting frame, with its base fixedly connected to the mounting frame via bolts. The connecting slide is slidably connected to the interior of the horizontal end of the mounting frame, and the telescopic end of the hydraulic cylinder is fixedly connected downward to the connecting slide. The hydraulic cylinder drives the lifting and lowering platen via the connecting slide to raise and lower the platen.

[0011] Furthermore, the cutting and pushing unit includes a punching machine and a fixed clamping block. The punching machine is installed on the right side of the upper end of the lifting and pressing plate. The punching machine's blade is arranged longitudinally and adjacent to the right end surface of the lifting and pressing plate. An L-shaped fixed clamping block is fixedly connected to the left and right sides of the upper end of the lifting and pressing plate. The fixed clamping block is clamped at the edge of the punching machine and is fixedly connected to the outer shell of the punching machine by bolts. The fixed clamping block is used to install and fix the punching machine, which is used to punch the end of the welding core extending from the metal material trough. The pressure rod can facilitate the punching operation while pressing the welding core.

[0012] Furthermore, the cutting and pushing unit also includes a mounting plate, a sleeve, a sliding frame, and a pusher block. The mounting plate is fixedly connected to the left side of the upper end of the base, and a row of sleeves is fixedly connected to the upper position of the mounting plate on the right side. The sliding frame is composed of five transverse rods and a longitudinal rod on the left side. The right end of each transverse rod is fixedly connected to a pusher block, and the five pusher blocks correspond horizontally to a metal trough. The mounting plate is used to install the sleeve and sliding frame. The sleeve allows the sliding frame to slide horizontally. By pushing the sliding frame from the outside, the pusher block can enter the metal trough, pushing the cut welding core outward a distance, making it easier for workers to receive the material on the right side.

[0013] Furthermore, the welding core straightening unit further includes limit rods and reinforcing back rods. The limit rods are fixedly connected to the left and right sides of the connecting slide. Both the limit rods and the connecting slide are vertically movably connected to the mounting frame. Four reinforcing back rods are fixedly connected to the outer circumference of the lower end of the connecting slide. The reinforcing back rods are arranged in an X shape and fixedly connected to the lower lifting and pressure plate. The limit rods enable the connecting slide to slide smoothly, and the reinforcing back rods provide a reinforced fixation effect on the back of the lifting and pressure plate, so that the thrust of the connecting slide is evenly applied to all parts of the lifting and pressure plate.

[0014] Furthermore, the cutting and pushing unit further comprises a receiving box, which is placed on the upper end of the base and on both sides of the processing table. The receiving box has a chamfered structure at one end close to the processing table. The receiving box is used to hold the cut welding core.
