Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a cold extrusion mold that facilitates material unloading. Background Technology

[0002] Cold extrusion is a common processing method in which a blank is placed in the cavity of a die or mold on a backing plate, and pressure is applied to the blank by an upper punch fixed on the press head of a pressure device at room temperature, thereby causing the blank to undergo plastic deformation and producing a part.

[0003] Most existing cold extrusion pressure equipment only has a simple upper punch for pressing down and a backing plate or lower die with a die cavity. During processing, the metal blank needs to be manually placed into the die cavity of the backing plate below the upper punch or the lower die, and then the upper punch is driven to move downward to complete the pressing. Finally, the formed workpiece is manually removed from the die cavity. Manual material feeding poses certain safety hazards and is not conducive to safe processing. Utility Model Content

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] Example 1: like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of a cold extrusion die for easy unloading. Figure 2 This is a front view of a cold extrusion die for easy unloading. The present invention provides a cold extrusion die for easy unloading, comprising a base 101, an upper punch 102, and auxiliary devices. The auxiliary devices include a turntable 103, a lower die 104, a gear 105, a rack 106, a drive assembly, a limiting assembly, and a lifting assembly. The drive assembly includes a guide rail 107 and a drive hydraulic cylinder 108. The limiting assembly includes a first support plate 109 and a first cylinder 110. The lifting assembly includes a lifting hydraulic cylinder 111 and a top plate 112. This design facilitates easy unloading of the finished product during cold extrusion processing and promotes safe processing.

[0018] In this embodiment, the upper punch 102 is located above the base 101. The base 101 is installed on the equipment workbench when it is working, and the upper punch 102 is installed on the equipment pressure head when it is working.

[0019] The turntable 103 is rotatably connected to the base 101 and is located on both sides of the base 101. The lower die 104 is fixedly connected to the turntable 103 and is located between the turntables 103. The gear 105 is fixedly connected to the turntable 103 and is located on the left side of the turntable 103. The rack 106 meshes with the gear 105 and is located below the gear 105. The drive assembly is located on the side of the base 101 near the rack 106. The limiting assembly is located on the side of the base 101 near the lower die 104. The lifting assembly is located on the side of the base 101 near the lower die 104. The turntable 103 has a T-shaped cross-section and is mounted on the base 101 via a rotating bearing. The lower die 104 is mounted on the turntable 103 via a positioning pin and bolts. The gear 105 is mounted on the mounting shaft end of the left side of the turntable 103 via a flat key and bolts. The rack 106 meshes with the gear 105. The drive assembly is located on the side of the base 101 near the rack 106 and is used to drive the rack 106 to move. The limiting assembly is located on the side of the base 101 near the lower die 104 and is used to improve the stability of the lower die 104. The lifting assembly is located on the side of the base 101 near the lower die 104 and is used to improve the stamping stability.

[0020] Secondly, the guide rail 107 is fixedly connected to the base 101 and slidably connected to the rack 106, and is located on the side of the base 101 closer to the rack 106; the driving hydraulic cylinder 108 is fixedly connected to the base 101, and the output end of the driving hydraulic cylinder 108 is fixedly connected to the rack 106 and located on one side of the base 101. The guide rail 107 is bolted to the base 101, and a sliding groove is provided on the guide rail 107 to facilitate the sliding of the rack 106. The driving hydraulic cylinder 108 is bolted to the base 101, and the output end of the driving hydraulic cylinder 108 is bolted to the rack 106.

[0021] Then, the first support plate 109 is fixedly connected to the base 101 and is located on the right front side and left rear side of the base 101; the first cylinder 110 is fixedly connected to the first support plate 109 and is located on the first support plate 109. The first support plate 109 is installed on the right front side and left rear side of the base 101 by positioning pins and bolts, so as not to affect the material picking. The first cylinder 110 is installed on the first support plate 109 by bolts. A circular abutment block is installed at the front end of the first cylinder 110, so that after the blank is placed in the lower die 104, the first cylinder 110 is activated, driving the circular abutment block to abut against the lower die 104, preventing it from shaking back and forth.

[0022] Finally, the lifting hydraulic cylinder 111 is fixedly connected to the base 101 and located on the base 101; the top plate 112 is connected to the output end of the lifting hydraulic cylinder 111 and located on the side of the lifting hydraulic cylinder 111 near the lower die 104. The lifting hydraulic cylinder 111 is symmetrically mounted on the base 101 by bolts, and the top plate 112 is connected to the output end of the lifting hydraulic cylinder 111 by bolts. When the lower die 104 is in the stamping position, the lifting hydraulic cylinder 111 is activated, pushing the top plate 112 to abut against the lower die 104, thereby improving stability during stamping.

[0023] When using this invention for cold extrusion processing of workpieces, it facilitates finished product unloading and ensures safe processing. During processing, the blank is placed in the lower die 104. At this time, the lifting hydraulic cylinder 111 is in the ejected state, the first cylinder 110 is in the extended state, and the driving hydraulic cylinder 108 is in the ejected state. Then, the control device press head moves, driving the upper punch 102 downward to cooperate with the lower die 104 to complete the cold stamping. Then, the press head moves upward to reset, driving the upper punch 102 to reset, the lifting assembly moves downward to reset, and the limit switch... After the components are reset, the driving hydraulic cylinder 108 actuates, driving the rack 106 to move, driving the gear 105 to rotate, and driving the turntable 103 to rotate, thereby rotating the lower die 104. At this time, the stamped part falls and is unloaded under the action of gravity. After completion, the driving hydraulic cylinder 108 actuates, thereby resetting the lower die 104, that is, the die cavity faces upward, and processing continues. The reset of the first cylinder 110 does not affect the rotation of the lower die 104, thus facilitating the unloading of finished products and ensuring safe processing during cold extrusion of workpieces.

[0024] Example 2: like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of a cold extrusion die that facilitates material unloading. Based on the first embodiment, this utility model provides a cold extrusion die that facilitates material unloading. The auxiliary device also includes a second support plate 201 and an oil pump 202.

[0025] The second support plate 201 is fixedly connected to the base 101 and located on the left side of the base 101; the oil pump 202 is fixedly connected to the second support plate 201 and located on the second support plate 201. The second support plate 201 is bolted to the base 101. The oil pump 202 is a centralized timed integrated oil pump, bolted to the second support plate 201. A copper pipe is provided at the oil outlet of the oil pump 202. The copper pipe is easy to shape. The oil outlet of the copper pipe is located at the top of the gear 105 but does not contact the gear 105, facilitating the dripping of lubricating oil. At the same time, an oil receiving tray is installed in the area below the guide rail 107 for oil collection.

[0026] In this embodiment, by setting the oil pump 202, oil can be drawn and transported at timed intervals to lubricate the transmission of the gear 105 and the rack 106.
