Description

Technical Field

[0001] This utility model belongs to the field of metal forming technology, and in particular relates to a vertical forging press. Background Technology

[0002] Forging equipment is a type of mechanical equipment used for metal forming and separation. It shapes metal by applying pressure, and its basic characteristics are high forming speed and high pressure, making it mostly heavy-duty equipment. It is suitable for different types of metal processing, including free forging, die forging, and other processes. For example, forging hammers are suitable for both free forging and die forging, and can process metal billets of various shapes. Die forging equipment can place heated billets in a forging die to form the shape, and is widely used in industries such as aerospace, automotive, and medical, producing various die forgings such as turbine blades, engine valves, and surgical forceps. In the forging equipment manufacturing industry, market competition is fierce, and companies need to continuously launch innovative and competitive products to stand out from the competition.

[0003] Chinese patent document CN204524135U discloses a horizontal parting multi-station flat forging machine, including a frame, a base on one side of the frame, a mold mounted on the base, a clamping device on the frame near the mold, and a forging slide connected to a power unit on the frame near the mold. A punch matching the mold is mounted on the front end of the forging slide. During operation, an electric motor drives a flywheel equipped with a pneumatic clutch. Upon a signal from the operator, a hydraulic station supplies high-pressure oil to the cylinder, pushing a double-acting lever to lower the clamping slide and clamp the mold and workpiece. The crankshaft, via a connecting rod, drives the forging slide and punch forward to perform the stamping operation. The clamping slide also maintains the clamping position. After the forging slide completes the stamping operation and returns to its top dead center, the lever is pulled to raise the clamping slide and release the workpiece, completing the operation. This achieves the clamping-stamping-releasing process requirements, significantly improving production efficiency.

[0004] In existing technologies, as described in the aforementioned patent, the punch of the forging equipment applies pressure from the side after the mold is closed, causing the metal roller to be molded. Due to the high pressure of the punch, the driving mechanism of the punch is correspondingly heavy and bulky. In order to reduce the transmission mechanism, the driving mechanism of the punch is often directly placed horizontally on the side of the mold, which also results in a large lateral dimension of the existing flat forging machine. The huge space occupation is equivalent to indirectly increasing the operating cost of the equipment. Utility Model Content

[0005] To overcome the problem that in existing forging equipment, the punch drive mechanism is horizontally positioned on one side of the die, resulting in a large lateral footprint and increased operating costs, this invention aims to provide a vertical forging equipment. By placing the rectangular slider for driving the punch movement below the worktable, the lateral space occupied is reduced. Furthermore, two right-angle slide rails and two detachable inclined slide rails facilitate the installation and maintenance of the rectangular slider.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a vertical forging press, comprising a vertical bed frame; a worktable, the worktable being horizontally arranged in the middle of the vertical bed frame; a first mold, the first mold being arranged at the center of the upper end of the worktable; a hydraulic cylinder, the hydraulic cylinder being longitudinally arranged at the upper end of the vertical bed frame; a second mold, the second mold being arranged at the lower end of the hydraulic cylinder; a punch, the punch being at least one, the punch being horizontally slidably connected to the upper end of the worktable; a rectangular slider, the rectangular slider being longitudinally slidably connected to the lower end of the vertical bed frame, the rectangular slider being drively connected to the punch; wherein, the rectangular slider is located directly below the worktable; two right-angle slide rails are longitudinally arranged at the rear of the lower part of the vertical bed frame; the two vertical sides of the rectangular slider at the rear are respectively located within the two right-angle slide rails; the two vertical sides of the rectangular slider at the front are respectively provided with guide angles; two inclined slide rails are detachably connected to the front of the lower part of the vertical bed frame; the two guide angles respectively abut against the two inclined slide rails.

[0007] The rectangular slider needs to provide enormous pressure to the punch; the two right-angle slide rails and the two inclined slide rails form the movement track of the rectangular slider, providing stable support and guidance for the rectangular slider, and also facilitating the installation, debugging and maintenance of the rectangular slider.

[0008] Furthermore, the lower end of the vertical bed frame is rotatably connected to a crankshaft located directly below the rectangular slider; an eccentric shaft is eccentrically arranged in the middle of the crankshaft; a second connecting rod is arranged between the eccentric shaft and the rectangular slider; the lower end of the second connecting rod is rotatably connected to the outer periphery of the eccentric shaft, and the upper end is rotatably connected to the rectangular slider.

[0009] Specifically, a speed-changing shaft is rotatably connected to the lower part of the vertical bed frame; a speed-changing gear is provided at one end of the crankshaft and is driven by the speed-changing shaft; a motor is provided at the lower end of the vertical bed frame; and the motor is driven by the end of the speed-changing shaft away from the speed-changing gear.

[0010] Furthermore, the worktable is provided with a lever rotatably connected to the worktable in the middle, and the number of levers is the same as the number of punches; a first connecting rod is provided between the lower end of the lever and the rectangular slider, the upper end of the first connecting rod is rotatably connected to the lower end of the lever, and the lower end is rotatably connected to the upper end of the rectangular slider; the upper end of the lever is used to drive the punches to slide back and forth.

[0011] Optionally, the lower end of the punch is provided with a driven groove; the upper end of the lever abuts against the inner wall of the driven groove.

[0012] Optionally, a transmission block is slidably connected longitudinally to the punch; the transmission block is rotatably connected to the upper end of the lever.

[0013] Preferably, the lever is L-shaped; the distance between the lever's rotating shaft and its upper end is less than the distance between the lever's rotating shaft and its lower end.

[0014] The L-shaped lever can also reduce the longitudinal height of the forging equipment, making the structure more compact.

[0015] Furthermore, a mounting plate is provided on the moving end of the hydraulic cylinder; the second mold is located at the lower end of the mounting plate; two guide columns are longitudinally arranged on the upper end of the mounting plate; and two guide seats are provided on the upper end of the vertical bed frame, which are respectively slidably connected to the two guide columns.

[0016] Specifically, a discharge rod is slidably connected longitudinally on the mounting plate; at least one support rod is provided on the discharge rod, and the support rod can optionally extend from below the second mold; a top rod for pushing down the discharge rod is provided on the upper part of the vertical bed frame.

[0017] After forging is completed, the formed workpiece may adhere to the bottom of the second mold. When the second mold rises, the push rod restricts the rise of the discharge rod, causing the support rod to extend from the bottom of the second mold and push the adhered workpiece downwards, causing it to fall off.

[0018] Furthermore, the punch has four punches evenly distributed along the circumference; the first mold is located at the center of the four punches.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model can be equipped with punches on all four sides of the mold, which can increase the number of parts processed in a single operation, and the pressure distribution is more uniform, ensuring structural strength and helping to increase the service life of the mold and equipment.

[0021] 2. This utility model is arranged from top to bottom as a punch, lever, rectangular slider and crankshaft, which reduces the horizontal space occupied by the equipment and makes the structure more compact; in addition, the lever can increase the pressure of the punch, which reduces the requirements for the motor.
