Description

Technical Field

[0001] The utility model relates to the technical field of mechanical stamping, in particular to a manual stamping fixture device. Background Art

[0002] At present, stamping processing is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet metal to deformation force and deform it in the mold, thereby obtaining product parts with a certain shape, size and performance.

[0003] Among them, the stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die. Common stamping dies can be divided into manual stamping and automatic stamping.

[0004] Manual stamping dies are often used on small and high-precision workpieces. However, when in use, the workpiece after stamping is often adsorbed on the stamping head, requiring the operator to spend time and effort to remove the workpiece from the stamping head. This process not only increases the pressure operation steps, but is also time-consuming and labor-intensive, greatly reducing the stamping efficiency. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a manual punching fixture device to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: a manual stamping jig device, comprising a base, a fixing frame fixedly mounted on one side of the top of the base, a mounting piece fixedly mounted on the top of the side wall of the fixing frame, a connecting piece fixedly mounted on the top of the side wall of the mounting piece, a handle rod rotatably mounted on the top of the connecting piece, a driving arm rotatably mounted on the side wall of the handle rod, an extrusion rod rotatably mounted on the other end of the driving arm, a driving seat fixedly mounted on the other end of the extrusion rod via a fixing piece, and a pushing mechanism mounted on the driving seat;

[0007] The pushing mechanism includes piston holes opened at the four corners of the driving seat, piston rods movably installed in the four groups of piston holes, stripping plates fixedly installed at the bottom of the piston rods, extrusion rings fixedly installed at the tops of the four groups of piston rods, and a spring sleeved on the outer wall of each group of piston rods.

[0008] As an optional solution of the technical solution of the present application, the inner cavity of the extrusion ring is movably connected to the extrusion rod, and the two sides of each group of springs are fixedly installed on the driving seat and the side wall of the extrusion ring respectively.

[0009] As an optional solution of the technical solution of the present application, a limiting cylinder is fixedly installed on the bottom of the connecting member, and the inner cavity of the limiting cylinder is movably connected to the extrusion rod, which can limit the extrusion rod.

[0010] As an optional solution of the technical solution of the present application, a punch head is detachably mounted on the bottom of the driving seat by bolts, and the punch head is movably connected to the inner cavity of the stripping plate, so as to facilitate the removal and replacement of the punch head.

[0011] As an optional solution of the technical solution of the present application, a support frame is fixedly installed on the side wall of the fixing frame, and a protrusion is fixedly installed on the bottom of the other end of the support frame. The protrusion corresponds to the extrusion ring and can extrude the extrusion ring.

[0012] As an optional solution to the technical solution of the present application, four groups of equally spaced limit rods are fixedly installed on the top of the base, the tops of the four groups of limit rods are movably connected to the top of the drive seat, and the outer walls of the four groups of limit rods are all sleeved with buffer springs. Each group of buffer springs is fixedly installed on the side walls of the base and the drive seat respectively, and can support the drive seat.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The technical solution of the present application continuously presses down the handle rod so that the driving arm continuously squeezes the extrusion rod, pushes the punch head on the driving seat, and punches the workpiece. At the same time, when the punch head completes punching the workpiece, the workpiece will most likely be adsorbed on the punch head due to friction. The operator can press down the extrusion ring in the pushing mechanism, and the four groups of piston rods at the bottom of the extrusion ring will push the stripping plate, efficiently pushing the workpiece off the punch head and quickly separating the workpiece from the punch head, avoiding the operator spending time and effort to remove the workpiece from the punch head.

[0015] 2. The technical solution of the present application is to fix a protrusion on the bottom of the other end of the support frame, and the protrusion corresponds to the extrusion ring. When the operator releases the handle rod, the driving seat will slowly move up due to the buffer springs sleeved on the four sets of limit rods until it is reset. As the driving seat continues to rise, the extrusion ring on the driving seat will be continuously squeezed by the protrusion on one side of the support frame. The workpiece on the punching head can be automatically detached from the punching head without manual operation, thereby further improving the workpiece punching efficiency.

[0020] See also Figure 1-2 The utility model provides a technical solution: a manual stamping fixture device, including a base 1, a fixing frame 11 is fixedly installed on one side of the top of the base 1, a mounting member 12 is fixedly installed on the top of the side wall of the fixing frame 11, a connecting member 13 is fixedly installed on the top of the side wall of the mounting member 12, a handle rod 14 is rotatably installed on the top of the connecting member 13, a driving arm 15 is rotatably installed on the side wall of the handle rod 14, an extrusion rod 16 is rotatably installed on the other end of the driving arm 15, and the other end of the extrusion rod 16 is fixedly installed on the driving base 2 through a fixing member, and a pushing mechanism is installed on the driving base 2;

[0021] The pushing mechanism includes piston holes 21 opened at the four corners of the driving seat 2, piston rods 22 movably installed in the four groups of piston holes 21, stripping plates 23 fixedly installed at the bottom of the piston rods 22, extrusion rings 24 fixedly installed on the tops of the four groups of piston rods 22, and springs 25 sleeved on the outer wall of each group of piston rods 22. The inner cavity of the extrusion ring 24 is movably connected to the extrusion rod 16, and the two sides of each group of springs 25 are fixedly installed on the driving seat 2 and the side walls of the extrusion ring 24 respectively.

[0022] In this technical solution, by continuously pressing down the handle rod 14, the driving arm 15 continuously squeezes the extrusion rod 16, pushing the punch head on the driving seat 2 to punch the workpiece. At the same time, when the punch head completes punching the workpiece, the workpiece will most likely be adsorbed on the punch head due to friction. The operator can press down the extrusion ring 24 in the pushing mechanism, and the four groups of piston rods 22 at the bottom of the extrusion ring 24 will push the stripping plate 23, efficiently pushing the workpiece off the punch head and quickly detaching the workpiece from the punch head, avoiding the operator spending time and effort to remove the workpiece from the punch head.

[0023] In some technical solutions, a support frame 3 is fixedly installed on the side wall of the fixing frame 11, and a protrusion 31 is fixedly installed on the bottom of the other end of the support frame 3. The protrusion 31 corresponds to the extrusion ring 24 and can extrude the extrusion ring 24.

[0024] In this technical solution, when the operator releases the handle rod 14, the drive seat 2 will slowly move up until it is reset due to the buffer springs sleeved on the four sets of limit rods 32. As the drive seat 2 continues to rise, the extrusion ring 24 located on the drive seat 2 will be continuously squeezed by the protrusion 31 on one side of the support frame 3. The workpiece on the punching head can be automatically detached from the punching head without manual operation, thereby further improving the workpiece punching efficiency.

[0025] In some technical solutions, four groups of equally spaced limit rods 32 are fixedly installed on the top of the base 1. The tops of the four groups of limit rods 32 are movably connected to the top of the drive seat 2. The outer walls of the four groups of limit rods 32 are all sleeved with buffer springs. Each group of buffer springs is fixedly installed on the side walls of the base 1 and the drive seat 2, respectively, to support the drive seat 2.

[0026] In this technical solution, when the drive seat 2 is squeezed by the extrusion rod 16, the four sets of limit rods 32 can be used to limit the drive seat 2 to ensure that the drive seat 2 moves up and down vertically. At the same time, the buffer spring installed on the limit rod 32 can automatically reset the drive seat 2.

[0027] In some technical solutions, a punch head is detachably mounted on the bottom of the driving seat 2 by means of bolts, and the punch head is movably connected to the inner cavity of the stripper plate 23, so as to facilitate the removal and replacement of the punch head.

[0028] In this technical solution, when the operator is punching different workpieces, he or she can install different types of punching heads by cooperating with the installation slots provided at the bottom of the drive seat 2 and quickly positioning them through bolts.

[0029] In some technical solutions, a limiting cylinder 33 is fixedly installed at the bottom of the connecting member 13 , and the inner cavity of the limiting cylinder 33 is movably connected to the extrusion rod 16 , which can limit the extrusion rod 16 .

[0030] In this technical solution, when the operator drives the handle rod 14 to squeeze the extrusion rod 16, the limiting cylinder 33 at the bottom of the connecting member 13 can effectively limit the extrusion rod 16 to ensure that the extrusion rod 16 moves up and down vertically.

[0031] When a manual stamping jig device is used, it should be noted that the utility model is a manual stamping jig device, and each component is a universal standard part or a component known to technical personnel in this field. Its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.

[0032] When in use, first use the hexagonal wrench to install the corresponding punching heads on the bottom of the driving seat 2, place the workpiece to be punched on the bottom of the driving seat 2, and align it with the punching heads. While holding the handle rod 14 and turning the handle rod 14, continuously press the handle rod 14 downward so that the driving arm 15 continuously squeezes the extrusion rod 16 to push the punching head on the driving seat 2 and punch the workpiece. At the same time, when the punching head completes the punching of the workpiece, the workpiece will most likely be adsorbed on the punching head due to friction. The operator can press down the extrusion ring 24 in the pushing mechanism, and the four groups of piston rods 22 at the bottom of the extrusion ring 24 will push the stripping plate 23, which is efficient. The workpiece on the punching head is pushed out and quickly separated from the punching head, avoiding the operator to waste time and effort to remove the workpiece from the punching head. At the same time, a protrusion 31 is fixedly installed at the bottom of the other end of the bracket 3, and the protrusion 31 corresponds to the extrusion ring 24. When the operator releases the handle rod 14, the driving seat 2 will slowly move up until it is reset due to the buffer springs sleeved on the four sets of limit rods 32. As the driving seat 2 continues to rise, the extrusion ring 24 on the driving seat 2 will continue to be squeezed by the protrusion 31 on one side of the bracket 3, and the workpiece on the punching head can be automatically separated from the punching head without manual operation, thereby further improving the workpiece stamping efficiency.
